As shown in FIG. 2, an upper partition portion 30 for partitioning these lateral directions is arranged between the refrigerating chamber 13 and the vegetable compartment 14. Between the vegetable compartment 14, the ice making chamber 15, and the upper freezing chamber 16, a central partition portion 31 that partitions these laterally is arranged. Between the ice making chamber 15, the upper freezing chamber 16 and the lower freezing chamber 17, a lower partition portion 32 for partitioning these lateral directions is arranged. Further, a vertical partition portion (not shown) for partitioning the vertical direction is arranged between the ice making chamber 15 and the upper freezing chamber 16.

A machine room 33 is provided on the back side of the upper end of the cabinet 12. In the machine room 33, a compressor 34 for compressing the refrigerant gas, a condenser for liquefying the high-pressure refrigerant gas (not shown), a cooling fan for cooling them, and the like are arranged. The compressor 34 arranged in the machine room 33 is not located exactly in the center in the left-right direction when viewed from the front of the refrigerator, but is arranged unevenly on the left side opposite to the right side of the refrigerator provided with the chilled chamber 27.

FIG. 4 is an enlarged view of the chilled chamber 27 shown in FIG. FIG. 5 is a view seen from the upper surface of FIG.

The chilled chamber 27 is composed of a ceiling plate 41, a left side plate 42, a right side plate 121, a partition wall 43, and an upper partition portion 30. The ceiling plate 41 and the left side plate 42 are arranged facing the refrigerating chamber 13. The right side plate 121 is configured to also serve as the left side surface constituting the cabinet 12. The partition wall 43 is arranged at a position facing the back plate 122 constituting the cabinet 12.

In the chilled chamber 27, a box-shaped, for example, resin chilled case 45 shown in FIGS. 6 and 7 is housed. FIG. 6 is a front view of the chilled case 45, and FIG. 7 is a view seen from the right side of FIG.

The chilled case 45 has an opening 451 on the front surface. Rails 452a and 452b extending to the back side are integrally formed below both inner side surfaces of the chilled case 45. The rails 452a and 452b are in a positional relationship facing each other. The rails 452a and 452b are composed of upper and lower rails, respectively.

The container 46 is freely put in and taken out of the opening 451 of the chilled case 45. The container 46 is integrally configured with the door cover 47 to form a drawer-type door. A handle 471 is integrally formed on the door cover 47. Guides (not shown) are integrally formed on both side surfaces of the container 46. The guide slides between the rails 452a and 452b, respectively. A roller may be attached to the guide to enable smooth movement on the rails 452a and 452.

A door panel 48 provided with an air layer is attached to the door cover 47. The door panel 48 is formed to have a size slightly wider than the opening 451 of the chilled case 45. The door cover 47 and the door panel 48 have a double structure with respect to the chilled chamber 27, which contributes to the improvement of the heat insulating effect and the energy saving.

A packing 49 is further attached to the outer periphery of the door panel 48. When the door cover 47 is closed, the packing 49 comes into contact with the open end surface 453 of the chilled case 45 in a slightly pressure-welded state.

The locking portions 50 are integrally formed in the directions orthogonal to both ends in the width direction of the door panel 48. As shown in FIG. 8, the locking portions 50 are formed by the first inclined portions 50B1 and 50B2 whose width gradually narrows as they approach the tip 50A, and the second inclined portions 50B1 and 50B2 which are slightly wider than the tip 50A near the tip. The inclined portions 50C1 and 50C2 are provided.

The upper and lower surfaces, the left and right side surfaces, and the back surface of the chilled case 45 are covered with a cooling cover 61 as shown in FIGS. 6 and 7. The cooling cover 61 is integrally formed of, for example, aluminum made of a metal having high thermal conductivity.

As shown in FIGS. 4 and 5, a cooling fan 62 for a chilled chamber is arranged at a cold air outlet 43a formed on a partition wall 43 facing the back surface of the chilled case 45. The cooling fan 62 for the chilled chamber serves to directly apply the cold air generated by the refrigerating evaporator 21 from the outside of the cooling cover 61. A temperature sensor 63 for a chilled chamber is installed on the upper surface of the chilled case 45 near the back surface. The chilled chamber temperature sensor 63 detects whether the temperature inside the chilled case 45 is at a set value, and uses it as a signal to control the chilled chamber cooling fan 62 based on the detection information.

The temperature sensor 63 for the chilled chamber was installed in the chilled case 45. When the metal cooling cover 61 is installed outside the chilled case 45, the temperature inside the chilled case 45 is difficult to read. By installing it in the chilled case 45, it is possible to read the accurate temperature.

The cooling fan 62 for the chilled chamber is smaller than the cooling fan 22 for the refrigerating chamber. The small size here means that at least the maximum power consumption by design is small and the air volume is also small.

As shown in FIGS. 6 and 7, resin catchers 51a and 51b are attached to both outer side surfaces of the chilled case 45. The catchers 51a and 51b serve to lock the locking portion 50 in a pressure-welded state between the packing 49 and the opening end surface 453.

The catchers 51a and 51b are attached to both outer surfaces of the chilled case 45, respectively. The catchers 51a and 51b have the same configuration. FIG. 8 shows the catcher 51b.

In FIG. 8, the movable portion 81 of the catcher 51b is rotatably supported around a support shaft 82 attached to the outer surface of the chilled case 45. Elastic members 83a and 83b are integrally formed in the rotation direction of the movable portion 81. A first piece 84a of the U-shaped stationary member 84 is arranged at a position facing the elastic member 83a. A second piece 84b of the stationary member 84 is arranged at a position facing the elastic member 83b. The stationary member 84 is integrally formed on the side surface of the chilled case 45. The stationary member 84 limits the movement of the elastic members 83a and 83b and prevents the movable portion 81 from rotating more than necessary.

An engaging roller 86a is rotatably attached to a position extending upward from the movable portion 81 in the left direction in the drawing via an integrally formed connecting rod 85a. An engaging roller 86b is rotatably attached to a position extending downward from the movable portion 81 in the left direction in the drawing via an integrally formed connecting rod 85b. The connecting rods 85a and 85b have elasticity.

When these intervals when the engaging rollers 86a and 86b are not engaged are set to S1, the relationship between the second inclined portions 50C1 and 50C2 and the interval S2 is set to S2 <S1. The interval S1 when the locking portion 50 is not engaged between the engaging rollers 86a and 86b may not be provided. That is, the engaging rollers 86a and 86b when not engaged may be in contact with each other.

The engaging rollers 86a and 86b in a state of being locked to the locking portion 50 are designed to be located at the second inclined portions 50C1 and 50C2.

Here, the operation of putting the container 46 in and out of the chilled case 45 will be described. First, the guide of the container 46 integrally configured with the door cover 47 is engaged with the rails 452a and 452b of the chilled case 45. When the door cover 47 is pushed along the rails 452a and 452b, the tips 50A of the left and right locking portions 50 reach the catchers 51a and 51b. When the door cover 47 is further pushed in, the tip 50A expands against the elasticity of the engaging rollers 86a and 86b in the directions of the arrows A1 and A2. When further pushed in, the engaging rollers 86a and 86b reach the second inclined portions 50C1 and 50C2 of the locking portion 50.

The engaging rollers 86a and 86b in the second inclined portions 50C1 and 50C2 urge the locking portion 50 in the direction of the arrow A3 based on the urging force in the directions of the arrows A1 and A2. The urging force in the direction of the arrow A3 is a force that presses the packing 49 against the open end surface 453 of the chilled case 45, and serves to seal the chilled case 45.

By the way, the cooling cover 61 of the chilled case 45 is exposed to cold air through the cold air outlet 43a by the operation of the cooling fan 62 for the chilled chamber. The cooling fan 62 for the chilled chamber rapidly cools the cooling cover 61 and forcibly generates convection in the chilled chamber 27, whereby the food can be rapidly cooled and the cooling time can be shortened. can. Since the cold air is not sent directly into the chilled chamber 27, it is possible to prevent the food from drying and the occurrence of temperature unevenness between the place where the cold air hits and the place where the cold air does not hit.

FIG. 9 schematically shows the electrical configuration of the refrigerator 11 centered on the control unit 91. The fans here are a cooling fan 22 for a refrigerating room, a cooling fan 26 for a freezing room, and a cooling fan 62 for a chilled room.

The control unit 91 follows a pre-stored operation control program, and based on signals from each sensor or the like, has a refrigerating room (refrigerating room 13 and vegetable room 14), a freezing room (ice making room 15, upper freezing room 16, and lower freezing). The chamber 17), the chilled chamber 27, and the like are controlled.

The sensors here are a refrigerating room temperature sensor 92, a freezing room temperature sensor 93, and a chilled room temperature sensor 63. The temperature information from these sensors is input to the control unit 91, respectively. The control unit 91 can perform operation according to the operation control program based on the temperature information of each sensor.

The refrigerating room temperature sensor 92 is installed in, for example, the refrigerating room 13 to obtain temperature information of the refrigerating room 13 and the vegetable room 14. Although the temperature sensor 92 for the refrigerating room is also used for detecting the temperature of the refrigerating room 13 and the vegetable room 14, the sensors may be installed individually.

The freezing room temperature sensor 93 is installed in any of the ice making room 15, the upper freezing room 16, and the lower freezing room 17, and obtains temperature information thereof. Sensors may be individually installed in the ice making chamber 15, the upper freezing chamber 16, and the lower freezing chamber 17.

Further, the temperature information in the chilled chamber 27 is obtained from the temperature sensor 63 for the chilled chamber.

The control unit 91 controls the cooling fan 22 for the refrigerating room, the cooling fan 26 for the freezing room, and the cooling fan 62 for the chilled room based on the set temperature information. In the control unit 91, the operation of the refrigerating room cooling fan 22 is synchronized with the operation of the refrigerating evaporator 21, and the operation of the freezing room cooling fan 26 is synchronized with the refrigerating evaporator 25.

The touch panel 28 includes a display unit 281 and an operation unit 282. The display unit 281 displays the temperature of the refrigerating room (refrigerating room 13 and vegetable room 14), the freezing room (ice making room 15, upper freezing room 16, lower freezing room 17), chilled room 27, and the like. The operation unit 282 manually sets the temperature of the refrigerating room (refrigerating room 13 and vegetable room 14), freezing room (ice making room 15, upper freezing room 16, lower freezing room 17), and chilled room 27 with respect to the control unit 91. Give instructions.

FIG. 10 shows a flowchart of the first embodiment in which the cooling fan 62 for the chilled chamber is controlled and the temperature of the chilled chamber 27 is controlled.

When the temperature setting of the chilled chamber 27 is set to, for example, 0 ° C., the control unit 91 recognizes the set temperature (step S1).

The control unit 91 determines whether or not the temperature information from the chilled chamber temperature sensor 63 of the chilled chamber 27 is the preset temperature of the chilled chamber 27 (step S2).

If it is determined in step S2 that the temperature of the chilled chamber 27 is not the set value (No), the process proceeds to step S3.

The control unit 91 determines in step S3 whether the chilled chamber 27 is higher or lower than the set temperature.

If it is determined in step S3 that the temperature of the chilled chamber 27 is lower than the set temperature (low), the chilled chamber cooling fan 62 is stopped (step S4), and the process proceeds to step S2.

When the control unit 91 determines that the temperature of the chilled chamber 27 is higher than the set temperature (high), the control unit 91 operates the cooling fan 62 for the chilled chamber (step S5), applies cold air to the cooling cover 61, and applies the cold air to the chilled chamber 27. The room temperature is controlled to be lowered, and the process proceeds to step S2.

In this way, the cooling fan 62 for the chilled chamber, which is exclusively provided for the chilled chamber 27, is controlled based on the temperature information of the temperature sensor 63 for the chilled chamber. This makes the temperature control of the chilled chamber 27 more reliable. Further, since the cooling fan 62 for the chilled room is smaller than the cooling fan 22 for the refrigerating room, it also contributes to the reduction of power consumption due to the operation.

When the operation of step S4 is stopped, the operation of the refrigerating evaporator 21 may be stopped at the same time. In this case, the transition to the set temperature of the chilled chamber 27 is accelerated, which contributes to the improvement of food preservation.

The cooling cover 61 does not necessarily have to be integrally formed, and the upper and lower surfaces, the left and right side surfaces, and the back surface are configured to be independent of each other, and a state in which a plurality of independent cooling covers 61 are in contact with each other is maintained. It may be configured to transfer cold heat.

Further, since the compressor 34 arranged in the machine room 33 is not exactly in the center position in the left-right direction when viewed from the front of the refrigerator, but is biased to the side opposite to the side provided with the chilled chamber 27, the center of gravity of the refrigerator is almost in the left-right direction. It can be positioned in the center and prevent the refrigerator from tipping over.

Further, the cooling cover 61 does not necessarily have to be configured to cover the upper and lower surfaces, the left and right side surfaces, and the back surface, and if it is possible to cool to the chilled temperature, it is configured to cover only the back surface and the upper surface. The area covered by the cooling cover 61 may be appropriately reduced. In particular, by adopting a configuration in which the upper surface is covered with the cooling cover 61, the air on the upper surface of the chilled chamber 27 is cooled, and a temperature difference is created between the air located on the lower surface and the air located on the upper surface in the chilled chamber 27. As a result, cooling can be effectively performed by causing vertical air convection in the chilled chamber 27.

Further, in the above embodiment, the machine room 33 is provided on the back side of the upper end portion of the cabinet 12, and the compressor 34 and the like are arranged in the machine room 33. It may be configured to be provided on the back side of the lower end portion.

(Embodiment 2)
The refrigerator of the second embodiment will be described. In this embodiment, while the chilled chamber cooling fan 62 is in operation, the rotation speed of the refrigerating chamber cooling fan 22 that cools the inside of the refrigerating chamber 13 is controlled to be reduced.

When the chilled chamber 27 is in the cooling mode, the rotation speed of the cooling fan 62 for the chilled chamber is increased to accelerate the cooling of the chilled chamber 27. At this time, the rotation speed of the cooling fan 22 for the refrigerating chamber was controlled to be reduced.

As described above, the air volume of the chilled chamber cooling fan 62 is smaller than that of the refrigerating chamber cooling fan 22. When the chilled chamber 27 enters the cooling mode, the cooling fan 22 for the refrigerating chamber is not good depending on the operating condition. That is, a phenomenon occurs in which the air volume of the chilled chamber cooling fan 62 is carried in the air blowing direction of the refrigerating chamber cooling fan 22 having a large air volume.

In this embodiment, in order to reduce the phenomenon that the air volume of the chilled chamber cooling fan 62 decelerates, the rotation speed of the refrigerating chamber cooling fan 22 is reduced, and cold air is surely blown to the chilled chamber 27 that needs to be cooled. Can be done.

(Embodiment 3)
The refrigerator of the third embodiment will be described. In this embodiment, when the refrigerating evaporator 21 is defrosted, the refrigerating chamber cooling fan 22 is controlled to rotate in the reverse direction.

When the refrigerating evaporator 21 is defrosted, the refrigerating chamber cooling fan 22 is rotated in the reverse direction, and the air from the refrigerating chamber, which is much higher than the temperature of the refrigerating evaporator 21, hits the refrigerating evaporator 21. This makes it possible to defrost the ice adhering to the refrigerating evaporator 21 without heating the defrosting heater.

(Embodiment 4)
11 and 12 describe the refrigerator of the fourth embodiment. FIG. 11 is a front view of the chilled chamber. FIG. 12 is a cross-sectional view taken along the line I-II of FIG.

As shown in FIGS. 11 and 12, this embodiment is made of a material having high thermal conductivity integrated with the inner back surface 45a, the upper surface 45b, the bottom surface 45c, and the left and right side surfaces 45d and 45e of the resin chilled case 45. The aluminum panel 111, which is the configured cooling cover, was arranged so as to cover the inside of the chilled case 45. The rails 452a and 452b on the left and right side surfaces 45d and 45e are not arranged.

In this embodiment, the aluminum panel 111 arranged inside the chilled case 45 exerts a wide cooling capacity in the chilled case 45, and it is possible to suppress temperature fluctuations in the chilled case 45. That is, it is possible to quickly cool from a state where the temperature is uneven in the chilled case 45 to a uniform chilled temperature range, such as when food is added or immediately after the start of cooling. Therefore, the chilled case 45 can improve the storage stability of the stored food.

The aluminum panel 111, which is a metal having high thermal conductivity, can suppress the influence of temperature from the refrigerating chamber 13 having a higher set temperature than the chilled chamber 27 even when the upper surface 45b is covered. In this case as well, the chilled case 45 can improve the storage stability of the stored food.

(Embodiment 5)
The refrigerator of the fifth embodiment will be described. In this embodiment, the outer surface other than the opening 451 of the chilled case 45 covered with the cooling cover 61 and the surface to be directly cooled from the cooling fan 62 for the chilled chamber is covered with a heat insulating material.

In this embodiment, the heat insulating material covering the outer surface of the chilled case 45 can suppress the temperature fluctuation in the chilled case 45. In this case, the chilled case 45 can improve the storage stability of the stored food.

It is not limited to the above-described embodiment. For example, as shown in FIG. 4, the upper partition portion 30 that partitions the refrigerating chamber 13 and the vegetable compartment 14 may be close to the temperature zone, and is not provided with heat insulation like the middle partition portion 31 and the lower partition portion 32. .. Therefore, the heat insulating material 71 is arranged on the vegetable chamber 14 side of the upper partition portion 30 corresponding to the chilled chamber 27, and the cover 72 is covered on the outside (lower side). This makes it possible to prevent the occurrence of dew condensation in the vegetable chamber 14 due to the temperature difference between the chilled chamber 27 at about 0 ° C. to 1 ° C. and the vegetable chamber 14 at about 5 ° C. to 7 ° C. Further, the heat insulating material 71 can suppress the temperature influence from the chilled chamber 27 to the vegetable chamber 14 or in the opposite direction.

The cooling fan 62 for the chilled chamber allows the rotation speed to be changed stepwise. The cooling fan 62 for the chilled chamber can improve the energy saving effect by adjusting according to the rotation speed setting. When the temperature setting of the chilled chamber 27 is the weakest mode, that is, when the refrigerating evaporator 21 is weak, the energy saving effect can be improved by stopping the cooling fan 62 for the chilled chamber.

Further, the operation of the cooling fan 62 for the chilled chamber can be controlled by manual operation. In this case, regardless of the operating state of the refrigerating evaporator 21, the temperature of the chilled chamber 27 can be lowered by operating the cooling fan 62 for the chilled chamber and sending cold air.

The cooling cover 61 does not have to be aluminum. The cooling cover 61 can prevent the food from drying by simply covering the chilled chamber 27 with another metal material having a high thermal conductivity so that the food is not directly exposed to cold air, and can improve the food storage stability. ..

Although some embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. These embodiments and variations thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
