Have been. This application includes a dehumidifying operation mode (hereinafter, referred to as a “land re-dry” mode) that makes the laundry dry and dry so that the laundry can be dried indoors, and a mite that dries indoors when going out. Dehumidification operation mode (hereinafter referred to as "outing" mode) that can prevent the occurrence of mold and mold (for example, dew condensation on windows and walls in winter, etc.) This is an operation mode (hereinafter, referred to as “condensation suppression” mode).

[0005] Here, the "landry" mode is for continuously operating the compressor and increasing the wind speed of the indoor fan so that the humidity is as low as possible. In the same manner as in the “standard” mode, and reduces the wind speed of the indoor fan. In the "condensation suppression" mode, the compressor is continuously operated and the wind speed of the indoor fan is reduced.

[0006]

In a conventional air conditioner, the temperature can be set arbitrarily, as described in Japanese Patent Application Laid-Open No. 61-59134, but the humidity of the user can be set. It could not be done arbitrarily. This is generally because air conditioners, especially small air conditioners, have many simple dehumidifying functions such as cooling operation with reduced air volume, and sufficient dehumidifying performance has not been obtained. Could not be done.

In the air conditioner described in JP-A-8-86494, various dehumidifying operation modes can be selected and set, and a normally used dehumidifying capacity (hereinafter referred to as a "standard" dehumidifying mode). The humidity is set lower than the humidity (in this case, 50%) obtained in the dehumidifying operation mode (hereinafter, referred to as “standard” mode) in the capacity, for example, a dehumidifying capacity of 50% humidity. The above-mentioned "Landry" mode and "Outing" mode,
This mode allows the air conditioner to be used in a special way, such as the "condensation suppression" mode.In such an environment where the air conditioner is performing a dehumidifying operation, the user can comfortably use it. Not something you can spend.

On the other hand, a sufficient amount of dehumidification can be obtained with the adoption of a reheating method and the like, and the need for comfort has increased. Control has come to be required.

[0009] An object of the present invention is to provide an air conditioner which can adjust the temperature and humidity according to the user's preference in order to meet such needs, thereby forming a more comfortable air-conditioning environment. To provide.

[0010]

In order to achieve the above object, the present invention provides a "standard" dehumidifying capability and a "strong" dehumidifying capability for lowering the humidity than the "standard" dehumidifying capability. Means are provided for enabling the user to arbitrarily select and set the dehumidifying capacity and the "holding" dehumidifying capacity that makes the humidity higher than the "standard" dehumidifying capacity.

The dehumidifying capacity can be arbitrarily selected and set by one operating means, and the "standard" dehumidifying capacity is automatically set at the start of the dehumidifying operation. By operating, any dehumidifying capacity can be selected and set. In addition, the selected and set dehumidifying capacity is displayed on the display unit of the remote controller as, for example, the humidity achieved by the dehumidifying capacity, so that the user can easily know the currently set dehumidifying capacity. Therefore, it is easy to determine what dehumidifying ability can be selected in accordance with the humidity desired by the user.

Also, by linking with a humidifier,
For example, even when it is very dry, such as in winter,
The user can set the humidity according to his / her preference.

The microcomputer 13 comprises a CPU 20 and a storage unit 21 for storing preset operation mode information.

The operation mode buttons for setting the cooling and heating operations and the buttons for setting the temperature which are usually provided are omitted.

In this embodiment, each of the cooling, heating and dehumidifying operations may be possible, or only the cooling and dehumidifying operations may be possible. Further, in addition to these operations, the vehicle may have a humidification or ventilation function, and the operation and functions are not limited.

Here, as the dehumidifying function, a dehumidifying ability for ensuring a sufficient amount of dehumidifying is required to enable humidity control. In addition, a reheating type dehumidifying function that can adjust the temperature of the air blown out from the air conditioner body 1 is desirable. Of course, a simple system may be used as long as the room temperature can be controlled by other means.

In the cooling operation and the heating operation,
Since it is performed in the same way as a normal air conditioner,
A description thereof will be omitted.

When the dehumidification button 14 of the remote controller 2 is pressed, the dehumidification operation starts. Here, a dedicated dehumidifying button 14 is provided for simplicity of description, but it may be used also as another operation button.

The dehumidifying button 14 has two functions. One is a function for starting the dehumidifying operation, and the other is a function for switching the dehumidifying ability.
When the dehumidification button 14 is pressed while the operation is stopped, the dehumidification operation is started at a specific dehumidification capacity (here, the set humidity is, for example, a “standard” dehumidification capacity of 50%). Each time the dehumidification button 14 is pressed, the "humidity" dehumidification ability to set the humidity to, for example, 40%, the "hold" dehumidification ability to set the humidity to, for example, 60%, and the "standard" dehumidification ability in this order. Ability switches cyclically.

The setting of the dehumidifying capacity by such an operation is performed as follows. That is, when the dehumidification button 14 is pressed on the remote controller 2, the storage unit 2 in the microcomputer 13
The set humidity is determined by the CPU 20 of the microcomputer 13 in consideration of the immediately preceding set humidity, which is the data stored in the storage unit 1, and the data representing the dehumidifying ability is displayed on the display unit 17 and the set humidity is displayed. The humidity information is transmitted from the transmission circuit 18 to the air conditioner body 1. In the air conditioner body 1, this information is received by the receiving circuit 4, and the CPU 10 of the microcomputer 3 checks the indoor humidity with the humidity detector 6, and performs the dehumidifying operation with the dehumidifying capacity according to the set humidity based on the received information. Is performed.

At this time, the room temperature is set by another means, or the microcomputer 3 of the air conditioner body 1 or the microcomputer 13 of the remote controller 2 determines an appropriate set temperature based on the surrounding environmental conditions and the set humidity. Is calculated automatically.

Thus, in the air conditioner body 1,
Along with the temperature, the humidity can be switched in multiple stages, and the dehumidifying operation of the dehumidifying capacity according to the set humidity and the set temperature is performed.

The operation / stop button 15 is used for starting operations other than the dehumidifying operation such as heating and cooling operations, and for stopping all operations. To start the dehumidification operation, the user presses the dehumidification button 14, and to stop the dehumidification operation, presses the operation / stop button 15.

FIG. 2 is an external view showing a front portion of the remote controller 2 shown in FIG. 1 where the operation section and the display section 17 are provided, and portions corresponding to FIG. 1 are denoted by the same reference numerals.

In the figure, a dehumidification button 14 is provided on the front of the remote controller 2, and here, "dehumidification"
It is assumed to be written.

The display section 17 shows all display contents displayed here, and actually, only those corresponding to the operation mode at that time are displayed.

"Standard" shown in the upper right part of the display unit 17,
The display contents of “strong” and “hold” indicate the dehumidifying ability set by operating the dehumidifying button 14 during the dehumidifying operation. When the dehumidification button 14 is pressed to start the dehumidification operation, "dehumidification" shown on the upper right portion of the display unit 17 is displayed, the dehumidification operation is started, and the dehumidification set at this time is performed as described above. Since the capacity is the “standard” dehumidification capacity, “standard” is displayed in the upper right portion of the display unit 17. During the dehumidifying operation, each time the dehumidifying button 14 is pressed, the dehumidifying capacity is switched as described above, and accordingly, the dehumidifying capacity is displayed in the order of "strong", "hold", and "standard" and cyclically. Is changed.

FIG. 3 is a flowchart showing the operation of the dehumidifying operation, and FIG.
FIG. 6 is a diagram showing a display example in FIG.

In FIG. 3, the air conditioner body 1 is
When the dehumidifying button 14 of the remote controller 2 (FIG. 2) is pressed (FIG. 1) in a stopped state (step 100), the dehumidifying operation is started (step 101), and “standard” dehumidifying is set and the remote controller 2 is set. As shown in FIG. 4 (a), the characters "standard" indicating the set dehumidification are displayed on the display section 17 of. This state continues unless the run / stop button 15 is pressed (step 103), and continues unless the dehumidification button 14 is pressed (step 104).

Thereafter, when the dehumidification button 14 is pressed (step 104), the set dehumidification shifts to "strong", and the changed setting is displayed on the display section 17 of the remote controller 2 as shown in FIG. The letters "strong" indicating dehumidification are displayed (step 105). This state continues unless the run / stop button 15 is pressed (step 106), and continues unless the dehumidification button 14 is pressed (step 1).
07).

Thereafter, when the dehumidification button 14 is pressed again (step 107), the set dehumidification shifts to "hold".
As shown in FIG. 4C, the display unit 17 of the remote controller 2
The character "hold" indicating the switched set dehumidification is displayed (step 108). This state continues unless the run / stop button 15 is pressed (step 1).
09), and continue as long as the dehumidification button 14 is not pressed (step 110).

Then, when the dehumidification button 14 is pressed again (step 110), the set dehumidification shifts to "standard", and the display is displayed on the display unit 17 of the remote controller 2 as shown in FIG. The character "standard" indicating the set dehumidification is displayed (step 102).

In the same manner, as long as the dehumidifying operation continues, the set dehumidification shifts in the order of "standard", "strong", "hold" and cyclically each time the dehumidification button 14 is pressed.

As described above, in this embodiment, since each humidity can be set, at the start of the dehumidifying operation, the dehumidifying capacity is set to "standard" where the set humidity is 50%. In the dehumidifying operation of the dehumidifying ability, for example, when there are many people in the room or the people move around and the humidity is felt high and the comfort is impaired, or when going home with such dehumidifying operation going out If you feel insufficient dehumidification, such as when you feel sweaty,
By pressing 4, the dehumidification capacity is switched to "strong", and the operation shifts to a dehumidification operation in which the set humidity is set to 40%.
When the dehumidifying operation of the "standard" dehumidifying capacity is performed, if the room feels too dry, or if it is desired to reduce the power consumption when performing the dehumidifying operation for a long time, the dehumidifying switch 14 is pressed twice. As a result, the dehumidifying ability is switched to "hold", the operation shifts to a dehumidifying operation in which the set humidity is set to 60%, and the dehumidifying ability can be properly used according to the user's preference.

As described above, the set humidity (dehumidification ability) can be switched and changed by operating the dehumidification button 14, but the order of changing the set humidity is not limited to this. Further, the expression of the dehumidifying ability is not limited to “standard”, “strong”, and “hold” as described above, and other expressions, for example, the value of the set humidity, that is, “standard” is “50”
% ”,“ Power ”is“ 40% ”, and“ Repression ”is“ 6 ”.
0% "may be expressed.

In a case where the region where the device is used does not become relatively hot and humid, a combination of “standard” and “hold” can simplify the selection operation and prevent unnecessary dehumidification operation due to erroneous selection. Power can be prevented.

FIG. 5 is a diagram showing the temperature distribution in the room in the dehumidifying operation and the normal cooling operation. FIG. 5 (a) shows the temperature distribution in the "standard" dehumidifying operation, and FIG. (B)
Indicates a normal cooling operation, in which case the set temperature is 28 ° C. automatically or by another means.

As is apparent from a comparison between FIGS. 5A and 5B, in the case of the dehumidifying operation, the flow of the air blown out from the outlet of the air conditioner main body is different from the set temperature. Although it is 27 ° C slightly lower by 1 ° C, the temperature is 28 ° C as a whole, but in the case of normal cooling operation, the cool and heavy air blown out from the outlet of the air conditioner body is It can be seen that the water flows toward the floor and a large temperature difference occurs between the floor and the upper part. For this reason, people feel as if their feet are cold, and comfort is impaired.

Of course, when the temperature is sufficiently high, such as in summer, the room can be cooled appropriately by the cooling operation, thereby providing a comfortable indoor environment. Driving provides a more comfortable indoor environment.

The dehumidifying capacity "standard", "strong" and "hold" in the above-mentioned dehumidifying operation means the rotational speed and operating rate of the compressor forming the refrigeration cycle (operation of the compressor per unit time). (Percentage of time) is set differently.

FIG. 6 is a diagram showing a dehumidifying operation mode of the second embodiment of the air conditioner according to the present invention. This second embodiment also has the same configuration as that of FIG.

In the figure, the dehumidifying operation mode in this embodiment is a mode classified as a difference in the use of an air conditioner, that is, a mode in addition to a mode based on a difference in dehumidifying ability in the first embodiment. Three modes of “landing”, “outing”, and “coupling suppression” are added, and each time the dehumidification button 14 (FIG. 1) is pressed, the six modes are switched in the direction of the arrow. Except for this, the configuration is the same as that of the first embodiment described above.

The dehumidifying operation mode according to the above is based on the result of the investigation of the needs of the user, as shown in FIG. In other words, the “landry” mode satisfies the needs of users who want to dry laundry indoors by the dehumidifying function of the air conditioner, and the “outing” mode is indoors even when going out. Is to satisfy the needs of users who want to reduce the proliferation of mites and molds by drying the water, and the "condensation suppression" mode is a user's need to prevent condensation that forms on window glass etc. in winter etc. Is satisfied.

FIG. 8 is a diagram showing conditions in the dehumidifying operation mode according to the above.

In the figure, the "standard" mode is a dehumidifying operation mode with the "standard" dehumidifying capacity set at the start of the previous operation. As described above, the set humidity is 50%, and the set temperature is set. This mode is continued unless the mode is switched to another mode by setting the room temperature at the start of operation and the wind speed of the indoor fan to be low, and unless the operation is stopped.
The dehumidifying operation of each of the “strong” and “hold” dehumidifying capabilities is the same as the dehumidifying operation mode with the “standard” dehumidifying capability only by changing the set humidity and the wind speed of the indoor fan.

In the "Landry" mode, the set temperature is set to the room temperature at the start of the operation, but the compressor is continuously rotated to keep the humidity as low as possible, and the wind speed of the indoor fan is also made strong. The operation time in this mode is limited to three hours in consideration of the drying time of the laundry and the like. When this operation time elapses, the dehumidification operation is stopped.

In the "outing" mode, the set temperature is set to approximately 5
0%, and the set temperature is the outside air temperature. This mode continues unless the wind speed of the indoor fan is reduced and the mode is not switched to another mode, and unless the operation is stopped.

In the "condensation suppression" mode, the compressor is continuously rotated ignoring the temperature, the humidity is reduced as much as possible, and the wind speed of the indoor fan is reduced. The operation time in this mode is limited to 2 hours in consideration of the time when the dew condensation disappears and the fact that if the operation is continued forever, the cooling state continues. In this mode, the dehumidifying operation is stopped after the operation time elapses.

As described above, in the second embodiment, it is possible to set the humidity switching for obtaining a comfortable indoor environment, and to set the air conditioner to dry clothes and mite.
It can also be used for applications such as indoor drying to prevent mold and air drying to prevent condensation.
In addition, only by operating the same dehumidifying switch 14, selection and setting of these modes can be easily performed.

FIG. 9 is an external view showing a third embodiment of the air conditioner according to the present invention, wherein reference numeral 22 denotes a humidifying unit, and portions corresponding to those in FIG.

In the figure, a humidifying unit 22 operable in conjunction with the air conditioner body 1 according to the third embodiment is provided in the air conditioner body 1 of the first or second embodiment. Are combined. Humidification unit 22
Is operated by a command from the air conditioner body 1 or a remote controller (not shown) during the dehumidifying operation.

That is, for example, when the user presses the dehumidification switch 14 (FIG. 1) in a very dry season such as winter,
The dehumidifying operation start mode is set to the “standard” dehumidifying capacity. At this time, the room humidity is lower than the set humidity of the “standard” dehumidifying capacity. At this time, the microcomputer 3 (FIG. 1) operates the humidifying unit 22 to increase the humidity. When the humidity increases and exceeds the set humidity, the microcomputer 3 stops the humidifying unit 22 and rotates the compressor. The air conditioner main body 1 starts the dehumidifying operation. and again,
When the dehumidification is performed and the humidity becomes lower than the set humidity, the humidifying unit 22 starts operating and the compressor of the air conditioner main body 1 stops, and thereafter, the set humidity is maintained in this manner. A dehumidification operation is performed. The same applies to the case of the dehumidifying operation of each of the "strong" and "hold" dehumidifying capabilities.

In general, it is considered that humidification and humidity control are rarely performed in a humid climate region such as Japan. However, in the Pacific Ocean side in winter, there is a case where the humidity becomes dry and low. . In such a case, as described above,
The combination of the air conditioner body 1 and the humidification unit 22 is effective.

In the third embodiment, the humidifying function is provided in a separate unit. Of course, the humidifying function may be integrated into the air conditioner body or combined with the humidifying function in FIG. Needless to say, the setting of humidity by the remote controller 2 as shown is similarly possible.

FIG. 10 is a block diagram showing a specific example of the refrigeration cycle in the air conditioner main body 1 described above, where 23 is a four-way valve, 24 is an outdoor heat exchanger, 25 is an electric expansion valve, and 26 is an electric expansion valve. Indoor heat exchanger, 26a is heating side, 26b is cooling side, 2
Reference numeral 7 denotes an expansion valve for dehumidification, reference numeral 28 denotes a refrigerant pipe, and portions corresponding to those in FIG.

This specific example is a reheating method using a refrigeration cycle capable of ensuring a sufficient amount of dehumidification and controlling the temperature of blown air.

Referring to FIG. 10, in this refrigeration cycle, the compressor 9, the four-way valve 23, the outdoor heat exchanger 24, the electric expansion valve 25, and the indoor heat exchanger 26 are sequentially connected by a refrigerant pipe 28. The indoor heat exchanger 26 is divided into a heating side 26a and a cooling side 26b in a refrigeration cycle by a dehumidification expansion valve 27.

Here, as the heat exchanger, a so-called cross-fin tube type heat exchanger comprising a large number of thin aluminum plates laminated and a copper pipe penetrated at right angles to this aluminum plate is assumed. The same applies to other types of heat exchange. The electric expansion valve 25 and the dehumidification expansion valve 27 are valves capable of adjusting the throttle action, and operate as follows.

That is, during the cooling or heating operation, the dehumidifying expansion valve 27 is fully opened (to the extent that the throttling effect is not caused or the throttling effect is minimal), and the electric expansion valve 25 is set to the throttling amount appropriate for cooling or heating. . At this time,
The indoor heat exchanger 26 functions as one evaporator or condenser on the refrigeration cycle.

During the dehumidifying operation, on the contrary, the electric expansion valve 25 is fully opened, and the dehumidifying expansion valve 27 is set to a throttle amount suitable for the dehumidifying operation. The refrigerant is condensed on the heating side 26a of the indoor heat exchanger 26 to heat the air, and evaporates on the cooling side 26b of the indoor heat exchanger 26 to cool the air. Thereby, dehumidification is performed. Then, by mixing these two airs and sending them out of the room, the temperature and humidity in the room are adjusted. In this case, the amount of dehumidification and the temperature of the blown air are adjusted by the rotation speed of the compressor 9, the rotation speed of the outdoor fan (not shown), the rotation speed of the indoor fan, the degree of throttle of the dehumidifying expansion valve 27, and the like. be able to.

[0065]

As described above, according to the present invention,
Along with the room temperature, the room humidity can be adjusted according to the user's preference, the room conditions, and the need to reduce power consumption. In addition, in the case of continuous use for a long time, etc., a dehumidifying operation that can obtain the effect of reducing power consumption without impairing comfort is also possible.

The switching of the room humidity can be performed by operating one operating means, and the dehumidifying operation of the currently set humidity is displayed on the display unit. It is possible to easily know if there is any, and it is possible to easily obtain an indoor environment that is surely suited to the user's preference.
