Abstract

PROBLEM TO BE SOLVED: To reduce cost of a vegetable container and to enhance space efficiency of a vegetable chamber. SOLUTION: A cold storage chamber 2 and a vegetable chamber 3 are provided in communication therebetween in the refrigerator 1. A cold storage cooler 26 is disposed on a back surface of the chamber 2, and a refrigerant is supplied selectively to a deep freezing cooler 51. Cold air generated by the cooler 26 is circularly supplied also to the chamber 3 via the chamber 2 by a cold storage cooling fan 28. Here, the fan 28 is driven by extending for a predetermined time from when supply of the refrigerant to the cooler 26 is stopped. Thus, since frost adhered to the cooler 26 is evaporated and a humidity of the cold air supplied to the chamber 2 is raised, an upper surface open type can be used as a vegetable container 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a vegetable compartment in a refrigerator compartment.

[0002]

Conventionally, in a refrigerator, cold air generated by a cooler is circulated and blown to a freezing room, and
The air outlet to the refrigerator compartment is opened and closed by a damper according to the set temperature of the refrigerator compartment (for example, 2 ° C.), so that the cool air is appropriately circulated and blown into the refrigerator compartment.

By the way, when a refrigerator is provided with a vegetable room,
If the cool air that was dried by cooling by the cooler was blown into the vegetable compartment, the vegetables would dry in a short time, so by covering the top surface of the vegetable container stored in the vegetable compartment with a moisture-permeable cover. Moderate humidity (about 90
%). However, since the cost of the moisture-permeable cover is high, its reduction has been desired. On the other hand, the vegetable room has a drawer structure, and the space above it is not being used effectively, so its use is desired.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refrigerator that can reduce the cost of vegetable containers and increase the space efficiency of the vegetable room.

[0005]

The refrigerator of the present invention has a vegetable compartment in a refrigerator compartment, a cooler compartment partitioned by a cooler compartment cover on the back of the vegetable compartment, and is housed in the cooler compartment. A refrigeration cooler to which a refrigerant is supplied is provided, and a cooling fan that circulates and sends the cool air generated by the refrigeration cooler to the refrigeration room and the vegetable room is provided, and supply of the refrigerant to the refrigeration cooler is provided. When stopped, a cooling unit for performing a humidifying operation for evaporating frost attached to the refrigeration cooler by continuing to drive the cooling fan is provided, and a top-open vegetable container stored in the vegetable compartment is provided. It is provided (claim 1).

According to such a configuration, when the refrigerant is supplied to the refrigerator cooler housed in the cooler room, the refrigerator cooler is cooled. When the cooling fan is driven in this state, the cool air generated by the cooling cooler is blown to the vegetable compartment through the refrigerator compartment, so that the temperature of the vegetable compartment decreases.

[0007] When the temperature of the refrigerating compartment falls to the set temperature, the cooling unit stops the supply of the refrigerant to the refrigerating cooler, but executes the humidifying operation by continuing to drive the cooling fan.

At this time, since the refrigeration cooler is frosted by the supply of the refrigerant, when the refrigeration unit executes the humidifying operation, the frost adhering to the refrigeration cooler evaporates.
This increases the humidity of the cool air circulated through the refrigerator compartment and the vegetable compartment, thereby preventing the vegetables stored in the vegetable compartment from drying out. Therefore, an inexpensive top open type vegetable container can be used.

In the above configuration, the cooling unit may perform the humidification operation by stopping the supply of the refrigerant to the refrigeration cooler and continuing to drive the cooling fan for a predetermined time. ).

According to such a configuration, when the supply of the refrigerant to the refrigeration cooler is stopped, the cooling unit performs the humidification operation by continuing to drive the cooling fan for a predetermined time from that timing. Thus, it is possible to prevent an excessive rise in the temperature of the refrigeration cooler due to the circulating airflow of the cool air while increasing the humidity of the cool air circulated through the refrigerator compartment and the vegetable room in a short time.

Further, a vegetable compartment may be provided in a lower portion of the refrigerator compartment, and the refrigerator compartment and the vegetable compartment may be separated by a transparent partition plate. According to such a configuration,
Because the refrigerator compartment and the vegetable compartment are separated by a transparent partition,
When the door of the refrigerator compartment is opened, the vegetables stored in the vegetable compartment can be confirmed through the transparent partition plate, which is excellent in usability. In this case, since the temperature of the refrigerator compartment and the temperature of the vegetable compartment are substantially the same, the transparent partition plate does not fog.

A low-temperature storage container may be arranged above the vegetable container, and a part of the cool air blown by the cooling fan may be directly blown into the low-temperature storage container. According to such a configuration, since an unused space exists above the vegetable container, the space efficiency of the vegetable room can be increased by disposing the low-temperature storage container in that space.

Here, a part of the cool air blown by the cooling fan is directly blown into the low-temperature storage container.
The temperature of the low-temperature storage container can be adjusted to a lower temperature than the vegetable room.

On the front surface of the cooler compartment cover, ribs are formed to protrude forward to prevent cool air blown from the refrigerator compartment to the vegetable compartment from being blown along the front surface of the cooler compartment cover. (Claim 5).

According to such a configuration, when air is blown from the refrigerator compartment to the vegetable compartment, the air tends to be blown along the front face of the cooler compartment cover located at the back of the vegetable compartment, but the front face of the cooler compartment , The rib is formed so as to protrude forward, so that the blowing path of the cool air blown along the front surface of the cooler chamber cover is changed to the front side by the rib. Thus, it is possible to prevent the cold air from returning to the refrigerator cooler in a short-circuit manner, thereby preventing the cooling efficiency from being reduced.

Further, the cooler room is formed such that a gap between a heat insulating material disposed on the front side of the cooler and the cooler room cover forms a suction path for cool air to the cooler. It may be constituted (claim 6).

According to such a configuration, a heat insulating material is arranged on the front surface of the refrigerator for cooling arranged in the cooler room, thereby insulating the vegetable room from the vegetable room. Now,
The cool air blown from the refrigerator compartment to the vegetable compartment is sucked into the cooler room through a suction port formed in the cooler room cover. At this time, since the suction passage leading to the refrigerator cooler is formed by the gap between the cooler room cover and the heat insulating material, the structure of the cooler room can be simplified, and the cost of the cooler room can be reduced. And miniaturization can be achieved.

Further, the refrigerator of the present invention is provided with a refrigerating cycle having a refrigerating cooler for generating cold air for freezing by driving a compressor and a refrigerating cooler for generating cold air for refrigerating. Refrigerator compartment with
When a freezing room in which the freezing cooler is arranged is provided, and a cooling fan that circulates and blows the cool air generated by the freezing cooler to the cold room is provided, and supply of the refrigerant to the cooler is stopped. Is provided with a cooling unit for performing a humidifying operation for evaporating frost adhering to the refrigeration cooler by continuing to drive the cooling fan, providing a vegetable room provided in the refrigeration room, and storing in the vegetable room. The present invention is provided with an open top vegetable container (claim 7).

According to such a configuration, the cooling unit selectively supplies the refrigerant to the refrigerating cooler and the refrigerating cooler, so that the refrigerating room and the freezing room are cooled by one cooler. In comparison, a low-power cooling unit can be used.

C), a chilled room (about 0 ° C), a refrigerator room (about 2 ° C), a vegetable room (about 3 ° C), and a wine cooling room (about 8 ° C).

FIG. 8 schematically shows a cooling unit of the refrigerator 1. In FIG. 8, the cooling unit 53 includes:
The inverter compressor 54, the condenser 55, the R-eva 26, and the F-eva 51 are connected to each other. That is,
An inverter compressor 54 is disposed in a machine room provided on the bottom surface of the refrigerator 1, and a discharge side of the inverter compressor 54 is connected to an inflow side of a condenser 55 disposed on the bottom surface of the refrigerator 1.

FIG. 9 shows the control timing of the cooling unit 53. In FIG. 9, the cooling unit 53
Executes the refrigerator compartment cooling mode (hereinafter, R cooling mode) when the temperature of the refrigerator compartment 2 becomes higher than the set temperature of 2 ° C., and the temperature of the freezer compartment 6 becomes higher than −20 ° C. At that time, a freezing room cooling mode (hereinafter, F cooling mode) is executed. That is, when the R-cooling mode is executed, the inverter compressor 54 is operated at an output of 140 W with the refrigerant supplied to the R-eva 26 by switching the three-way valve 56, and when the F-cooling mode is executed, the three-way valve 56
The inverter compressor 54 is operated at an output of 90 W while the refrigerant is supplied to the F-eva 51 by the switching.

Here, the cooling unit 53 includes the R fan 2
8 and the F fan 52 are driven in accordance with the execution of the R cooling mode and the F cooling mode. However, in the R fan 28, the supply of the refrigerant to the R evaporator 26 is stopped for a predetermined time (for example, 5 minutes). ) To perform the humidification operation that is continuously performed. This is to evaporate the frost adhering to the R-eva 26 to increase the humidity of the cool air blown from the refrigerator 1, and the fact that the humidity of the cool air blown to the refrigerator compartment 2 is increased as described above It is a feature of.

Further, by selectively supplying the refrigerant to the R-eva 26 and the F-eva 51, these evaporators 26 and 5
Since the cooling unit 1 is cooled in a time-sharing manner, the refrigeration capacity of the refrigeration unit can be reduced as compared with a configuration in which the refrigerator and the freezing room are cooled by one cooler. It is possible to use a compressor that consumes power, which is also a feature of the refrigerator.

Next, the operation of the above configuration will be described. When the temperature of the refrigerator compartment 2 exceeds the set temperature of 2 ° C,
The cooling unit 53 executes the R cooling mode. That is,
By switching the three-way valve 56, the inverter compressor 54 is operated at an output of 140 W with the refrigerant supplied to the R-eva 26. In such an operating state, the R-eva 26 is cooled to about −18 ° C. Therefore, when the R fan 28 is driven according to the execution of the R cooling mode, cool air of about −18 ° C. is blown into the refrigerator compartment 2. You.

Here, although the refrigerator compartment 2 and the vegetable compartment 3 are partitioned by a transparent partition plate 47, a communication port 48 is formed at a predetermined portion of the transparent partition plate 47 and communicates therewith.
By executing the cooling mode, the cool air blown to the refrigerator compartment 2 is also blown to the vegetable compartment 3 and the temperature of the vegetable compartment 3 decreases. In this case, the cold air blown into the vegetable compartment 3 slightly absorbs heat when passing through the refrigerator compartment 2 and rises in temperature.
When the refrigerator compartment 2 is cooled to 2 ° C., the temperature of the vegetable compartment 3 is cooled to 3 ° C., which is slightly higher than the temperature of the refrigerator compartment 2.

On the other hand, the temperature of the freezer 6 is the set temperature.
When the temperature exceeds 20 ° C., the cooling unit 53 executes the F cooling mode. That is, by switching the three-way valve 56, the inverter compressor 54 is operated at an output of 90 W while the refrigerant is supplied to the F-eva 51. In such an operating state, the F-eva 51 is cooled to about −25 ° C., and when the F fan 52 is driven according to the execution of the F cooling mode, the cool air of about −25 ° C. Room 6
It is blown to.

In the temperature switching chamber 5, a temperature corresponding to the set use is set to about -25 with opening and closing of the damper.
The temperature is adjusted to the temperature according to the use set by the user by blowing the cool air of ° C.

In the present embodiment, when the execution of the R cooling mode is completed as described above, the cooling unit 53 sets the R fan 2 for a predetermined time (for example, 5 minutes).
8 is continued. As a result, the R-evaver 26, which has been cooled to about −18 ° C. by executing the R-cooling mode, supplies the refrigerator compartment 2 and the vegetable compartment 3 with the supply of the refrigerant stopped.
The cold air of about 2 to 3 ° C., which has been circulated, is blown, so that the frost adhering to the R-eva 26 evaporates in a short time. As a result, the refrigerator compartment 2 and the vegetable compartment 3
The humidity of the cool air circulated through the air quickly rises from about 35% to 70% or more.

As a result of the high humidity cool air being blown into the vegetable compartment 3, the vegetables stored in the open top vegetable container 30 are prevented from drying out. It becomes possible.

On the other hand, the chilled case 31 placed on the upper part of the vegetable container 30 is directly blown by cold air of about −18 ° C. from the R-eva 26. At this time, the chilled case 31
Is closed by the cover 36 and the return hole 46 is formed in the cover 36, so that the cool air blown to the chilled case 31 is blown to the vegetable compartment 3 through the hole 46 formed in the cover 36. You. As a result, the temperature of the chilled case is 1 temperature lower than the temperature of the vegetable room 3 (about 3 ° C.).
Cool to ~ 2 ° C lower temperature (about 1-2 ° C). In this case, since the hole 46 formed in the cover 36 also serves as a handle, there is no need to specially form a handle for the handle on the cover 36.

As described above, since a part of the cool air from the R evaporator 26 is blown to the chilled case 31 in the vegetable compartment 3, the pressure on the suction side of the R fan 28 can be increased. Compared to a configuration in which all of the cool air from 26 is blown to the refrigerator compartment 2, the pressure loss difference of the R fan 28 can be reduced, and the cooling efficiency can be increased.

When the vegetable container 30 is pulled out, the chilled case 31 mounted on the upper portion of the vegetable container 30 is also pulled out as shown in FIG. In this state,
When taking out the food stored in the chilled case 31, the cover 36 covering the chilled case 31 is pushed backward.
Then, the cover 36 locked by the first stopper 37 of the chilled case 31 gets over the first stopper 37, and the cover 36 slides backward as shown in FIG. The cover 36 is positioned relative to the chilled case 31 when the cover 36 is locked to the portion 38. At this time, the cover 36 slides while sliding on the ridge 39 having a height of 0.5 mm and a width of 2 mm formed on the flange 31 b of the chilled case 31. The range is limited to an extremely narrow range corresponding to the ridge portion 39. Thus, even if the entire chilled case 31 is formed of a transparent resin, the appearance of the chilled case 31 does not deteriorate.

When taking out the vegetables stored in the vegetable container 30, the chilled case 31 located above the vegetable container 30 is pushed backward. Then, the pulley 33 provided on the bottom surface of the chilled case 31 escapes from the stopper portion 34 of the pulley bead 32 formed on the inner wall surface of the vegetable container 30 and advances on the pulley bead 32, as shown in FIG. As shown, it is positioned when it comes into contact with the rear end of the pulley bead 32. In this state, the upper surface of the chilled case 31 is completely closed by the cover 36.

When the cover 36 of the chilled case 31 is moved to the back in a closed state or a half-open state, the guide portion 41 formed on the chilled case 31 as shown in FIG. Guide 4 formed
As the chilled case 31 moves to the back, the cover 36 moves to the back along the inner box bead 43 as the chilled case 31 moves to the back.

When the vegetable container 30 is moved backward in order to store the vegetable container 30 in the vegetable compartment 3, the vegetable container 30 moves backward with the chilled case 31 stopped.
When the pulley 33 of the chilled case 31 is located at the rear end of the stopper portion 34 of the pulley bead 32 of the vegetable container 30, the chilled case 31 is integrally formed with the vegetable container 30.
Will be positioned within.

According to the present embodiment, in addition to the F-eva 51, the R-eva 26 is provided independently as the cooling unit 53, and the vegetable compartment 3 is provided below the refrigeration compartment 2 so as to communicate with it. At the end of the mode, the operation of the R fan 28 is continued for a predetermined time to execute the humidification mode in which the frost attached to the R-eva 26 is evaporated in a short time, so that the refrigeration room 2 and the vegetable room 3 are circulated and blown. The humidity of cold air can be increased. Therefore, as compared with the conventional configuration in which the upper surface of the vegetable container is covered with the moisture-permeable cover, the moisture-permeable cover can be omitted, the cost of the vegetable container 30 can be reduced, and the space for disposing the moisture-permeable cover can be reduced. As a result, the space efficiency of the vegetable room 3 can be increased.

Since the refrigerator compartment 2 and the vegetable compartment 3 are partitioned by the transparent partition plate 47, when the door 7 of the refrigerator compartment 2 is opened, the vegetable compartment 30 is connected to the vegetable compartment 30 via the transparent partition plate 47. The stored vegetables can be checked, and the structure is excellent for use.

Further, a chilled case 31 is mounted on the upper part of the vegetable container 30, and cool air from the R
Since the air is blown directly to the container 1, the space above the vegetable container 30 can be used to expand the chilled room.

Further, in the R-evaporation chamber 20, the suction path 25 leading to the R-evapor 26 is formed by the R-evaporation chamber cover 21 and the heat-insulation material 24 by devising the arrangement of the heat-insulating material 24. The structure of the chamber 20 can be simplified, the cost can be reduced, and the size can be reduced.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. 14. The same parts as those in the first embodiment are denoted by the same reference numerals. Description is omitted. The second embodiment is characterized in that the R fan 28 of the R-evacuation chamber 20 is attached from the front side of a heat insulating material for forming the R-evacuation chamber 20.

That is, a heat insulating material 61 for forming the suction passage 60 is integrated with the heat insulating material 59 attached to the back surface of the R-evaporation chamber cover 21.
8 is mounted from the front side. Thus, when the R fan 28 is driven, the cool air is blown forward as indicated by the arrow in the drawing.

On the other hand, an air outlet 62 is formed in the heat insulating material 59, and the air outlet 62 communicates with the air outlet 22 formed in the R-evaporation chamber cover 21. Then, cool air is blown to the chilled case 31 from the outlet 22 of the R-evaporation chamber cover 21.

According to the second embodiment, even if the air flow path is reversed by attaching the R fan 28 to the heat insulating material 61 for forming the R evaporator chamber 20 from the front side. Since the ventilation path is formed by devising the shape of the heat insulating material 61, similar to the first embodiment,
The configuration of the R-evaporation chamber 20 can be simplified and the size can be reduced.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. The present invention may be applied to a refrigerator having only the refrigerator compartment 2 and the vegetable compartment 3. When driving the R cooling fan in a state where the supply of the refrigerant to the R evaporator is stopped, the rotation speed of the R cooling fan may be increased. In this case, the humidity of the cool air circulated and blown to the refrigerator compartment and the vegetable compartment can be increased in a short time.

[0065]

As is apparent from the above description, according to the refrigerator of the present invention, the cold air generated by the cooling cooler disposed in the cooler room is blown by the cooling fan so that the refrigerator room and the vegetables are cooled. When circulating air to the room, the cooling fan is driven in a state where the supply of the refrigerant to the refrigerator cooler is stopped to evaporate frost adhering to the refrigerator cooler, thereby circulating the refrigerator room and the vegetable room. Since the humidity of the cool air to be blown is increased, the vegetable container housed in the vegetable room can be of an open-top type, so that the cost of the vegetable container can be reduced and the space of the vegetable room can be reduced. It has an excellent effect that the efficiency can be increased.
