Technical field

The present invention relates to a refrigerator having a refrigerating compartment with an opening and closing door on the upper part of the main body, and in particular to a refrigerator having a voice device which is easy to check the operation status of the refrigerator and has good operability.

current technology

The refrigerator, which is called the current main refrigerator, has a refrigerator compartment at the top, a freezer compartment at the bottom, a vegetable compartment between the freezer compartment and the refrigerator compartment, and a compressor behind the vegetable compartment and the freezer compartment. Heat exchangers, fans and cold air distributors. In this conventional refrigerator, cool air generated in a heat exchanger is supplied to each chamber through a fan and a cool air passage. In particular, for supplying cool air to the refrigerator compartment, the cool air passage formed behind the refrigerator compartment is generally branched to both sides with the lighting device in the center, and cool air is supplied to the refrigerator compartment from the branched cool air passage. In addition, there is also a refrigerator in which a duct extending up and down is formed between the branched ventilation passages, a circulation fan is installed in the duct, and the cold air in the refrigerating room sucked by the circulation fan is blown out through the duct to make the cold air circulate in the air. Circulation in the refrigerator. Such a refrigerator is described, for example, in JP-A-9-42820 (Conventional Example 1) and the like.

In addition, conventionally, there is a refrigerator in which an operation display unit is provided on the surface of an opening and closing door, and the operation display unit has lamps for displaying various switches and switching states of storage compartments, and the like. Such refrigerators are described, for example, in JP-A-11-118312 (conventional example 2), JP-A 2000-88445 (conventional example 3), JP-A 2000-74548 (conventional example 4), and the like.

In particular, in Conventional Example 4, it is disclosed that an operation panel is provided on the door of the refrigerator compartment, a liquid crystal display device is arranged in the center of the operation panel, and a plurality of operation switches are provided around the liquid crystal display device. The switch is used to set the indoor temperature of the freezer, switching room, and refrigerating room. The liquid crystal display device and the setting switch are connected to the control device, and the control device controls the compressor, the fan, the shock absorber motor (Dampamo-ta), etc. In order to make each room become the indoor temperature set by the operation switch, its operating status is displayed on multiple areas of the liquid crystal display device, and the lighting of the liquid crystal display device is only turned on for the necessary time.

In addition, refrigerators that automatically issue a voice warning when the door is forgotten to be closed are known, and such refrigerators are described in, for example, JP-A-60-42577 (Conventional Example 5).

In the refrigerator of this conventional example 5, when the freezer door or the refrigerator door is opened, the door detection device is turned on, and the output is output from the OR circuit. According to this, one pulse is output from the one pulse generator, and thus the voice storage device outputs Corresponding speech (for example " please note, filling is too much ") and send out voice by loudspeaker. In addition, when the state of the freezer door or the refrigerator door being opened continues, the voice storage device operates with the output from the AND circuit after a certain period of time (about 30 seconds) has elapsed by means of the pulse generator and the delay circuit, and the output is consistent with the above-mentioned pronunciation. Speeches of different content (eg "the door is open, please close") are repeated by the speaker. Moreover, when the two doors are closed, the door detection device is disconnected, the output from the OR circuit disappears, and the inputs of the 1 pulse generator, the delay circuit, and the pulse generation circuit are all 0, and are reset.

Also, there is known a refrigerator in which a teaching function can be set by short-circuiting pins for setting a control board provided on the back of the refrigerator (conventional example 6). As the pin method short-circuiting, there is a method to insert a set pin by preparing an exclusive connector.

In the above-mentioned conventional example 1, when the amount of cool air supplied to the refrigerator compartment is increased, there is a problem that food stored in the refrigerator compartment freezes, and it is necessary to supply cool air with a controlled supply amount. Therefore, food stored in the refrigerator cannot be cooled in a short time. In addition, in order to cool the refrigerator evenly, a circulating fan is installed in the refrigerator, but since the air outlet on the duct is fixed at a specific position, for example, when placing high-temperature food that causes uneven temperature in the refrigerator, , the temperature unevenness cannot be quickly eliminated.

In addition, in recent refrigerators, while increasing the number of operation switches, product functions consisting of multiple operating functions, timing functions, teaching functions, alarm functions, button lock functions, etc. have become complicated. Ease of use becomes important.

However, in the above-mentioned conventional example 2, the operating state of the refrigerator is set and displayed by the operation display unit, but the content of the display is simple, and the operating state such as the cooling air supply state of the refrigerator cannot be displayed. In addition, in Conventional Example 3, the specific internal structure of the operation display unit is described, but since the content of the display is not described, the display of the operating state is not considered.

In the above-mentioned prior art example 4, although the operating state is displayed in a plurality of regions of the liquid crystal display device with the necessary time, and the usability is improved, but only the improvement of the visibility of the operating state is stopped, so only There is a limit to the improvement of usability by the display of the liquid crystal display device.

In addition, in the above-mentioned prior art example 5, a warning is automatically generated by voice only when the door is forgotten to be closed, and no voice is generated for setting a variety of operating functions with a plurality of operation switches, and the various product functions related to the refrigerator have not been improved. Ease of use.

In Conventional Example 6, in order to set or cancel the teaching function, it is necessary to prepare a dedicated connector to short-circuit and release the pins of the control board housed on the back of the refrigerator compartment, which is very troublesome.

In addition, some refrigerators sold on the market are equipped with a technology that positively and automatically changes the supply direction of cold air to quickly eliminate temperature unevenness in the refrigerator room, but there is no such thing as setting the temperature through the user's operation operation part. The supply direction of cold air, and the technology to monitor or observe its status from outside the refrigerator.

FIG. 33 is a front view of the refrigerator which concerns on one embodiment of this invention. Fig. 34 is a longitudinal sectional view showing a schematic structure of the refrigerator.

The refrigerator body 1c is formed of an outer case 2c, an inner case 3c, and a heat insulating material 4c filled therebetween, and has a box-like shape. The main body 1c of the refrigerator forms a plurality of storage rooms that can accommodate storage items. These store rooms have a refrigerating room 5c, a vegetable room 6c, a switch room 7c, an ice making room 8c, and a freezing room 9c from above.

In addition, an ice-cooling room (hereinafter referred to as an ice room) 5a is provided at the bottom of the refrigerating room 5c.

Doors 10e-14e which open and close the storage rooms are provided on the front side of these storage rooms 5c-9c. In this embodiment, a revolving door 10e rotatably supported by a supporting part provided on either side of the refrigerator is provided in front of the refrigerator compartment 5c. And the front surface of the freezer compartment 9c is provided with the drawer doors 11e-14e supported by guide rail etc. so that it can draw out freely. In addition, the revolving door 10e forming the refrigerator compartment 5c is provided with a plurality of grooves 5b that swell toward the inside of the refrigerator compartment 5c in a closed state.

The refrigerating compartment 5c, the vegetable compartment 6c, the switch compartment 7c, the ice making compartment 8c and the freezing compartment 9c are divided by a heat insulating partition wall 15c having a heat insulating material in order to reduce heat transfer between the two compartments. A cooler room 18c in which a cooler 16c and a cooler fan 17c are arranged is formed behind the refrigerator compartment 5c, the vegetable compartment 6c, the switching compartment 7c, the ice making compartment 8c, and the freezer compartment 9c. In order to interpose the heat insulation partition wall 15c between this cooler chamber 18c and the vegetable compartment 6c, the heat insulation partition wall 15c is extended in the up-down direction behind the vegetable compartment 6c.

In the cooler chamber 18c, the fan 17c for coolers is arrange|positioned above the cooler 16c. Above the cooler chamber 18c, a cold air passage 19c that communicates with the refrigerating chamber 6c and the cooler chamber 18c, in which the cold air cooled by the cooler 16c flows, is formed. The fan 17c rotated by 20c supplies cool air to the refrigerator compartment 5c through the cool air passage 19c. In order to adjust the temperature of the refrigerating room 5c to an appropriate range, the cooling air passage 19c is provided with an air flow adjustment damper 21c for adjusting the amount of cooling air supplied to the refrigerating room 5c.

In addition, the cold air cooled by the cooler 16c simultaneously flows out from the fan 17c toward the front, and descends in the cold air passage 22c arranged between the cooler compartment 18c and the vegetable compartment 6c or the switching compartment 7c, the ice making compartment 8c, and the freezing compartment 9c. And flow into the switching chamber 7c, the ice making chamber 8c, and the freezing chamber 9c, and cool the switching chamber 7c, the ice making chamber 8c, and the freezing chamber 9c.

In order to make the cold air passing through the air volume adjustment damper 21c through the cold air passage 19c pass through the air volume adjustment damper 21c from the cooler chamber 18c to rise along the wall surface of the inner box 3c on the back side of the refrigerator compartment 5c, the cold air passage 19c is formed. In addition, this cool air passage 19c branches into a plurality of passages at the rear of the refrigerator compartment 5c. The branched cold air passage extends up and down on both sides of the back surface of the refrigerator compartment 5c. In the refrigerator compartment 5c, a plurality of shelf plates 23c arranged at intervals in the vertical direction are arranged, and a space in the refrigerator compartment 5c is vertically partitioned. This divided space communicates up and down through the gap between the groove 5b of the door and the shelf 23c. A plurality of cold air outlets are formed vertically to communicate with each space formed by the shelves 23c and the branched cold air passages to allow the cold air to flow out toward the cooling groove 5b.

A substantially cylindrical ventilation duct 25c and a refrigerator fan 26c for supplying cool air from the refrigerator compartment 5c to the ventilation duct 25c are disposed at the rear central portion of the refrigerator compartment 5c between the plurality of cool air passages. The ventilation duct 25c is vertically long, and the fan 26c for refrigerator compartments is arrange|positioned under it, and these are extended up and down in the back center part of the refrigerator compartment 5c.

The fan 26c for a refrigerating room sucks in the cold air of the refrigerating room 5c from the refrigerating room cooling air inlet provided in the left and right sides, and supplies the blown cold air to the ventilation duct 25c. The ventilation duct 25c is formed in a hollow shape, and air flows inside, and a plurality of duct outlets are formed along the upper and lower sides corresponding to the space divided by the shelves 23c of the refrigerator compartment 5c, and are supplied by the fan 26c for the refrigerator compartment. The cold air is discharged into the refrigerating chamber 5c from the duct outlet as shown by the arrow in FIG. 2 . Ventilation duct 25c, fan 26c for a refrigerator, and other configurations are set so that the discharge speed of cold air discharged from the duct discharge port is higher than the discharge speed of cool air from the cool air discharge port. The cold air sent to the space divided by each shelf 23c in the refrigerator compartment 5c flows to the front of the refrigerator compartment 5c, and when passing through the front end of each shelf 23c, it flows from between the shelf 23c and the groove 5b as shown by the arrow. The gap between drops. The descending cold air flows toward the rear of the refrigerator compartment 5c above the shelf surface on the upper side of the ice chamber 5a as indicated by the arrow, and is sucked by the fan 26c for the refrigerator compartment through the suction port. Thus, the fan 26c for refrigerator compartments and the ventilation duct 25c are means which circulate the cold air in the refrigerator compartment 5c. The cold air ventilation path of the refrigerator compartment 5c constituted by the fan 26c for the refrigerator compartment and the ventilation duct 25c does not pass through the cooler 16c, and is independent from the cooler 16c. Refrigerator room fan 26c is a centrifugal fan that sucks cold air from the front side of the refrigerator room that flows in from lower suction inlets on both sides of the back side of refrigerator room 5c, and blows it toward upper air duct 25c.

A motor 29c for driving the ventilation duct 25c is disposed above the ventilation duct 25c, and rotates the cylindrical ventilation duct 25c extending vertically along an axis in the vertical direction. The direction of the discharge port is changed by the rotation of the ventilation duct 25c, and the direction of the cold air discharged from the duct discharge port into the refrigerator compartment 5c is adjusted.

The wind direction plate 30c arranged in the ventilation duct 25c is located at a position corresponding to each duct outlet, such as directly above the duct outlet, crosses the passage in the ventilation duct 25c, and directs the refrigerated air flowing from the bottom to the top in the ventilation duct 25c. A part of indoor cold air changes direction to the direction of the refrigerator compartment 5c and easily flows out from the duct outlet at a high speed.

The cold air discharged into the refrigerator compartment 5c from the outlet for blowing the cool air supplied from the cooler compartment 18c and the duct outlet for blowing the cool air sucked in from the refrigerator compartment 5c is partially passed through the fan 26c for the refrigerator compartment and the ventilation duct 25c in the refrigerator compartment. 5c, however, a part of the remaining cold air flows into the vegetable compartment 6c from the opening 31c formed under the refrigerator compartment 5c and communicated with the vegetable compartment 6c. The cold air flowing into the vegetable compartment 6c flows toward the front of the refrigerator above the container in the vegetable compartment 6c, and after the front portion of the container descends, it flows toward the rear through the lower part of the container, and passes through a return channel (not shown) formed in the vegetable compartment 6c. The opening and the cold air return path return to the cooling chamber 18c.

In this way, the cold air in the refrigerator has: the cold air cooled by the cooler 16c returns to the cooler chamber 18c from the cooler chamber 18c by the rotation of the cooler fan 17c through the refrigerator chamber 5c or the vegetable chamber 6c; The cold air is sucked in by the fan 26c for a refrigerator and flows out from the outlet of the cold air through the ventilation duct 25c into the refrigerator chamber 5c and flows into the circulation path of the fan 26c for a refrigerator again.

The centrifugal fan 26c is arranged below the ventilation duct 25c, and cool air inlets are formed on the left and right sides of the fan 26c for a refrigerator. An inflow passage 35c is formed between the suction port and the fan 26c for the refrigerator compartment. Furthermore, a refrigerator compartment temperature sensor which is a temperature detecting device for detecting the temperature of the cool air flowing through the inflow path 35c is arranged. Based on the temperature detected by the refrigerating compartment temperature sensor, the temperature in the refrigerating compartment 5c is determined, and the flow of cold air is regulated by the air volume regulating damper 21c. For example, when the determined temperature is higher than a predetermined temperature and cooling of the refrigerator compartment 5c is required, the air volume adjustment damper 21c is opened. In addition, when the determined temperature is lower than a predetermined temperature and cooling of the refrigerator compartment 5c is unnecessary, the air volume adjustment damper 21c is closed.

In addition, in order to detect the temperature of the storage space divided by each shelf 23c in the refrigerator compartment 5c, at the height positions corresponding to the storage spaces of each shelf 23c and on the left and right side wall surfaces between the shelf 23c and the groove 5b, A direction determination sensor 37c as a temperature detection means is arranged on the upper side. This direction determination sensor 37c detects the temperature of the cool air flowing forward in the storage space partitioned by the shelf 23c. When the cold air reaches the front end of the shelf 23c, it cools the groove 5b and descends toward the bottom of the refrigerator in the space between the groove 5b, toward the cold air inlet 27c of the refrigerator fan 26c disposed below and formed in the ice chamber 5a. Go below the opening 31c.

The direction determination sensor 37c detects the temperature of cool air flowing through the storage space partitioned by the shelf 23c. When the stored items are placed on the upper surface of the shelf 23c, the flowing cool air exchanges heat with the stored items, and the temperature changes. Since the direction determination sensors 37c are arranged vertically and vertically on the wall surfaces forming the left and right sides of the refrigerating chamber 5c, the temperature of the cold air flowing on both sides above each shelf 23c is detected, and the left and right sides are detected by comparing the temperatures on both sides. side temperature is high. When the temperature of the detected high side is higher than the set temperature of the refrigerating chamber 5c, the ventilation duct 25c is rotated so that the direction of the cold air discharge port of the ventilation duct 25c is towards the predetermined direction of the high side of the detected temperature, Then stop turning. Then, the cold air supplied to the ventilation duct 25c is blown out from the outlet toward the side of the refrigerator compartment 5c where the detected temperature is high by the rotation of the refrigerator fan 26c.

The operation panel 56c is arranged on the front portion of the refrigerator door 10e located at the front upper part of the refrigerator, and the operation switch 60c and the display part 70c are placed side by side on the operation panel 56c. The display part 70c is formed in a vertical shape, and the operation switch 60c is displayed along A plurality of portions 70c are provided in the longitudinal direction. The detailed structure thereof will be described later.

The compressor 38c is arranged on the lower rear surface of the refrigerator main body 1c, forms a part of the refrigeration cycle, and compresses the refrigerant. In addition, in the control device 39c (see FIG. 5 ), the main microcomputer 51c is arranged on the upper back of the refrigerator main body 1, and the operation unit microcomputer 52c is arranged on the back side of the operation panel 56c.

Hereinafter, the driving operation of the compressor 38c will be described with reference to FIGS. 35 and 36 . Fig. 35 is a circuit diagram showing a driving device for a compressor according to the present invention, and Fig. 36 is a characteristic diagram showing DC voltage and flow rate with respect to the rotational speed of the compressor.

The compressor 38c has a compressor driving motor 44y connected to a commercial power supply 41y through an inverter circuit 42y and an inverter circuit, and a compression mechanism 45y that is rotated by the motor 44y to compress refrigerant. The commercial power supply 41y is an outlet in a general household in the case of a household refrigerator, and supplies power to the refrigerator through a plug (not shown) inserted into the refrigerator side.

The frequency conversion circuit 42y has diodes 42a to 42d constituting a rectification circuit, a reactor 42e constituting a step-up clipping circuit, a diode 42f, and a switching element 42g which is a power supply device such as a transistor. The rectification circuit converts the received AC power into DC power and outputs it to the boost clipping circuit. This step-up clipping circuit is connected to the output side of the rectifier circuit, and the voltage is raised by forcibly flowing an input current due to the switching operation of the switching element 42g and the energy storage effect of the reactor 42e. The boosted DC voltage is supplied to the smoothing capacitor 46y, and a stable DC power is output.

Hereinafter, this step-up operation will be described in more detail. The side of the diode 42a is positive, and when the switching element 42g is turned on, the current is in the form of the AC power supply 41y, the diode 42a, the reactor 42e, the switching element 42g, the diode 42d, and the AC power supply 41y. Flowing in sequence, electromagnetic energy is accumulated in the reactor 42e. At this time, when the switching element 42g is turned off, a current flows from the reactor 42e to the smoothing capacitor 46y through the diode 42f for preventing backflow, and the electromagnetic energy is transferred to the capacitor 46y, and the voltage of the capacitor 46y rises. As a result, the DC stage voltage is increased.

An inverter 43y is connected to the capacitor 46y for converting a direct current into an alternating current for generating a rotating magnetic field. This rotating magnetic field is used to rotate the motor 44y. The compression mechanism 45y driven by the motor 44y is not shown in detail, but it is housed in an airtight container together with the motor 44y, and is mainly a reciprocating compression mechanism. In addition, a rotary type or a scroll type compression mechanism may be used.

When the time setting switch 65y is pressed, the timer display portion 75c of the display portion 70c lights up, and the refrigerating compartment temperature display portion 76b of the refrigerating compartment display portion 76c and the freezer compartment temperature display portion 77b of the freezer compartment display portion 77c are changed to Displays generated by timer functions. That is, after pressing the time setting switch 65y, the minute can be set when the refrigerating compartment temperature setting switch 66y is pressed, and the second can be set when the freezing compartment temperature setting switch 67y is pressed. Then, when the time setting switch 65y is pressed again, the timer mode is set, and counting of the set time is started. In addition, during timing operation, LED65c lights up. When the timing setting switch 65y is pressed again, the set timing is reset.

The refrigerating compartment temperature display part 76b and the freezer compartment temperature display part 77b are 7-segment display modes with two digits, and they are placed adjacently up and down. The order is easy to confirm both. In particular, by arranging the timer display part 75c, the refrigerator compartment temperature display part 76b, and the freezer compartment temperature display part 77b up and down, the visibility can be improved remarkably. And the setting of the second of the freezer compartment temperature display part 77b is performed by the length (10 seconds in this Example) of the multiple of 5 seconds divided into 60 seconds in multiple stages. Thereby, the setting of the second can be performed in a short time, and good usability can be obtained.

By pressing the refrigerating compartment temperature setting switch 66y, the refrigerating compartment temperature setting mode is set, and by repeatedly pressing the refrigerating compartment temperature setting switch 66y, the temperature setting of the refrigerating compartment 5c is set to 5 stages from weak to strong, and the other steps are performed. At the same time as the cooling operation at the set intensity, the cursor of the refrigerator compartment setting display 76a (weak to strong) moves. As mentioned above, this refrigerating compartment temperature setting switch 66y also serves as a sub-setting switch of the timer. The temperature of the refrigerator compartment 5c detected by the temperature sensor is displayed on the refrigerator compartment temperature display part 76b.

When the freezer compartment temperature setting switch 67y is repeatedly pressed, the temperature setting of the freezer compartment 9c is set in five stages from strong to weak, and the cooling operation of the set intensity is carried out, and the freezer compartment setting of the freezer compartment display part 77c The cursor of the fixed display 77a (weak to strong) is moved.

The ice making switch 68y also serves as an ice making and cleaning switch, and the ice maker can be cleaned by pressing the ice making switch 68y for a long time, for example, for 5 seconds. During ice machine cleaning, the cleaning display 78c is illuminated.

The operation switches 61y to 68y have three types of buttons 61b to 68b in combinations of shapes and sizes. Thereby, the types of the operation switches 61y to 68y can be easily recognized from the buttons 61b to 68b, and the operations can be reliably performed. In particular, the three types of buttons 61b to 67b of the operation switches 61y to 68y are made into different shapes from the buttons 61b to 63b for setting the rapid cooling operation and the buttons 66b and 67b for setting the temperature of the storage room, and the settings are switched. The button 64b for different operation functions of the chamber 70c is made smaller than the other buttons 61b-63b, 66b, 67b. Thereby, the buttons 61b to 63b, 66b, and 67b that are generally used frequently can be easily operated, and the possibility of erroneously operating the button 64b that particularly affects the cooled food that is generally used less frequently can be reduced. In addition, specifically, the buttons 61b to 63b are large substantially elliptical buttons, the buttons 66b and 67b are large substantially rectangular buttons, and the buttons 64b and 68b are small substantially rectangular buttons.

Here, the voice output of the voice device 80c will be described. When the rapid cooling switch 61y is pressed, the rapid cooling and thawing display 71a of the display unit 70c lights up, the buzzer 54c outputs a buzzer, and then the speaker 83c outputs, for example, "Rapid cooling starts." Then, when the setting of the rapid cooling operation is completed after a predetermined period of time, the speaker 83c outputs, for example, "rapid cooling complete."

Similarly, when the rapid freezing switch 63y is pressed, the rapid freezing display part 73a of the display part 70c lights up, the buzzer 54c outputs a buzzer, and then the speaker 83c outputs a voice such as "Start rapid freezing." Then, when the setting of the rapid cooling operation ends after a predetermined time, the speaker 83c outputs, for example, a voice saying "quick freezing is completed."

In addition, the 7 temperature zones of freezing, soft freezing, slight freezing, ice temperature, lower temperature refrigeration, refrigeration, and wine refrigeration can be switched by the switching chamber setting switch 64. After the beep is output, a voice such as "Set to slightly chilled. Meat and fish are suitable for processing. Since they are kept slightly frozen, they are suitable for boiled or grilled food" is output. The operation function and its specific content can be notified. In this way, in this embodiment, there is a function of notifying the operating function of the set switch chamber 7c and its specific content by voice.

When the setting of the operation switch is completed, even in any setting, a voice corresponding to each setting function is output after the buzzer is output.

Hereinafter, the teaching function will be described. The teaching function is a function to improve the teaching effect when displaying on the storefront as described above. That is, when a customer purchases a refrigerator, he or she actually purchases a refrigerator by confirming the specifications and design of the refrigerator from a real product or a product sample in a store or the like. Therefore, a teaching function is provided so that customers can easily understand the functions and features of the refrigerator. In this teaching function, in the state where the door 10e of the refrigerator compartment is opened, by simultaneously pressing the ice making switch 68y and the freezer compartment temperature setting switch 67y for several seconds (for example, 5 seconds), the teaching mode is determined and the display unit 70c is activated. 79c is displayed during teaching.

As a teaching function, for example, during the rapid cooling operation of cooling the food in the aforementioned refrigerator compartment 5c or the rapid defrosting operation of putting frozen food in the refrigerator compartment 5c for thawing, the fan 26c and the cylindrical ventilation duct 25c are placed in the refrigerator compartment 5c. They are operated with the refrigerator door closed, but in this way, customers do not understand how they operate. Therefore, when the teaching function is set, the fan 26c and the cylindrical ventilation duct 25c can be operated even when the refrigerator compartment door 10e is opened.

When teaching the function, for example, when the temperature switch 66y of the refrigerator is pressed, the voice output "refrigerator is in rapid state. If it is beer, it only needs to be placed in the refrigerator for 30 minutes before drinking. It only takes 15 minutes from rapid defrosting to cutting. Of course, it is amazingly energy-efficient because it is dual-PAM. Advertisement of the functions or features of such a refrigerator as the world's first dual-PAM refrigerator.

Considering that the teaching function is mostly used in a large place with a noise of about 80dB, the state of the teaching function is confirmed by the operation unit microcomputer 52c of the operation board 55c, and the audio signal is amplified by the amplifier 82c to increase the volume. In addition, when using in a place where the noise is relatively small, the volume of the voice during the teaching function can be set to the level of normal use by pressing the rapid freezing switch 63y for a long time, for example, for a set time (for example, 3 seconds). By pressing the button again for a long time, the volume can be set to a high level.

In addition, during the teaching function, the switching room display part 74c of the display part 70c flashes the display of freezing, soft freezing, slight freezing, ice temperature, low-temperature refrigeration, refrigeration, and wine refrigeration in a period of 1 second, for example, to attract customers. Attention. At this time, when it is set as the switch room of the switch room setting switch 64y, the set switch room display lights up for a predetermined time, and at the same time, the function of the set switch room is output by voice from the speaker 83c. After the specified time, the display will be blinked periodically. Thereby, the teaching effect can be further improved.

When the rapid freezing switch 63y is pressed for a long time, the voice volume can be changed as described above in the teaching function, but in normal use, ON and OFF of the voice output can be set. However, since the teaching function is a function for explaining the product to the customer, it is set so that it does not turn OFF even if the above-mentioned operation voice output is performed during the teaching function. This prevents the voice output from being turned off by mistake during the teaching function.

Similarly, when the rapid cooling switch 61y is pressed for a long time, the button lock function of button lock is set so that even if a child fiddles with the switch, the indoor state will not be changed. Nor does it become a button lock. In this way, it is possible to prevent button locks from being erroneously performed during the teaching function.

The above-mentioned teaching function has conventionally been switched by short-circuiting the pins set on the control board provided on the back of the refrigerator. In order to short-circuit this pin, it is necessary to prepare a special connector. In addition, when selling a refrigerator displayed on the storefront, it sometimes happens that the special connector is forgotten to be removed, which causes abnormal operation in the customer's home. Therefore, by setting the teaching function using the switch of the operation board 55 in the operation panel 56 as described above, the conventional dedicated connector can be eliminated.

In addition, in a store or the like, in a state where the teaching function is set, etc., the refrigerator is often turned off after the store is closed. In this case, the teach function must be set again the next day. Therefore, when the teaching function is set once, even if the power of the refrigerator is cut off, the state of the teaching function will be stored in the storage part 53c of the non-volatile memory, and even if the power is turned on again, it can be operated as the teaching function. The state of the refrigerator is stored in the base plate 55c.

However, when the refrigerator is sold with the teaching function set, the refrigerator will not work normally even if the customer connects it to the refrigerator for normal operation. When the refrigerator is powered on, the buzzer 54c outputs a buzzer for a predetermined time (for example, 10 seconds), and then outputs a voice, for example, "The teaching function is set." In addition, a teaching-in-progress display 79c is displayed on the display unit 70c. Thereby, even if it is sold with the teaching function set, when the customer turns on the power of the refrigerator, it is possible to notify the state of setting the teaching function. In addition, the cancellation of the teaching function can be performed by performing the same operation as the setting again.

Next, the alarm function will be described. As mentioned above, the alarm function is a function to call attention based on the detection results of various sensors. For example, when a door is forgotten to be closed or a malfunction occurs, an alarm is issued by a buzzer or voice.

In addition, when refrigerator compressor noise is generated, it has not been possible to easily know at what compressor rotation speed the noise is generated in the past. Therefore, in this embodiment, the 7 segments of the refrigerating compartment temperature display part 76b and the freezing compartment temperature display part 77b can represent the rotational speed of the compressor currently in operation or the characters or numbers matched with the rotational speed. As a method of displaying it, it can be displayed by simultaneously pressing, for example, the refrigerating compartment setting switch 86c and the freezing compartment setting switch 87c for a few seconds using the switches of the operation board 55 . In addition, since this operation is performed by maintenance service personnel when a failure occurs, in order not to display the compressor rotation speed even if the customer performs this operation by mistake, for example, it is set to perform the above-mentioned operation with the refrigerating compartment door 10e of the refrigerator open. The compressor speed is displayed when the switch is operated.

Hereinafter, the basic control operation of the operating unit microcomputer 52c will be described with reference to FIGS. 41 to 44 . 41 to 44 are flow charts of the operation of the control unit microcomputer in the refrigerator of the present invention.

If it is not pressed for a long time in this determination, the rapid freezing operation mode is activated (step 142c). The action of this rapid freezing operation mode, when setting, at the same time as setting the rapid freezing operation function, light the rapid freezing display 73a, and then output the voice in conjunction with the output of the buzzer, and after a predetermined time, Turn off the blast freeze display 73a.

When pressing for a long time in step 141c, after the voice/buzzer switching mode is activated (step 143c), the process proceeds to step 140c. This voice/buzzer switching mode, as previously mentioned, whenever the rapid freezing switch 63y is pressed for a long time, the switching voice/buzzer is all output, only the buzzer is output, and both are not output. Certainly.

In step 150c, it is determined whether the switching chamber setting switch 64y is pressed, and when the switching chamber setting switch 64y is not pressed, it proceeds to step 160c, and when pressed, the switching chamber operation mode is activated (step 151c), and then it proceeds to step 160c. The action of switching the chamber setting operation mode, every time the switching chamber setting switch 64y is pressed, the switching chamber 7c will be switched to freezing, soft freezing, slight freezing, ice temperature, lower temperature refrigeration, refrigeration, wine refrigeration. Simultaneously with the operation of the seven temperature zones, at the time of setting, voice output is performed in conjunction with the output of the buzzer sound, and the set switching room display part 74c is turned off.

In step 160c, the temperature display of the refrigerator compartment 5c and the freezer compartment 9c is carried out. The temperature display detects the temperature of the refrigerator compartment 5c and the freezer compartment 9c by the temperature sensor, receives the temperature data from the main microcomputer 51c, and displays them in the refrigerator compartment. On the temperature display part 76b and the freezer compartment temperature display part 77b.

Next, in step 161c, it is determined whether the refrigerating compartment temperature setting switch 66y has been pressed, and if not pressed, it proceeds to step 163c, and when pressed, the refrigerating compartment temperature setting mode is activated (step 162c). In this refrigerating compartment temperature setting mode, each time the refrigerating compartment temperature setting switch 66y is pressed, the cooling intensity of the refrigerating compartment 5c is switched and set in five steps, and the set refrigerating compartment setting display 76a is illuminated. When it is set, the output of the voice is performed in conjunction with the output of the buzzer.

Next, in step 163c, it is determined whether the freezer compartment temperature setting switch 67y has been pressed, and if not pressed, it proceeds to step 170c, and when pressed, the freezer compartment temperature setting mode is activated (step 164c).
