Description

[Detailed description of the invention] (a) Industrial application field The present invention comprises a first storage chamber at a freezing temperature and a second storage chamber at a higher temperature,
It relates to a cooling storage where each is cooled by a separate cooler.

(b) Conventional technology In conventional refrigerators of this type, as shown in Utility Model Publication No. 3405/1983, cold air from the cooler is distributed and circulated between the freezer compartment and the refrigerator compartment to cool the compartments to their respective temperatures. . However, with this configuration, the relatively odor-laden air inside the refrigerator passes through the cooler and is also circulated to the freezer compartment, which causes the odor to transfer to the water used to make ice in the freezer compartment, degrading the flavor. Therefore, it has been proposed to provide separate coolers for each chamber and circulate cold air in each chamber, as disclosed in Japanese Utility Model Publication No. 43-25181.

(c) Problems to be solved by the invention The cooler must be defrosted periodically, and this defrosting water is led to the evaporation tray in the machine room through a drain pipe as in the above-mentioned Japanese Utility Model Publication No. 43-25181. However, if the drain pipe from the refrigerator compartment is simply connected to the drain pipe from the freezer compartment as in the publication, the freezer compartment and the refrigerator compartment will be communicated via the drain pipe, and the above-mentioned inconvenience will not occur. There were still problems that occurred.

The present invention has been made to solve this problem.

(d) Means for Solving the Problems The present invention has a first storage compartment that is at a freezing temperature, a second storage compartment that is at a higher temperature, and a first storage compartment that cools the first storage compartment. In the cooling storage, which is equipped with a cooler and a second cooler that cools the second storage chamber, each of which uses a blower to circulate cold air to cool each chamber, and an evaporation tray is arranged in the machine room. , a first drain pipe extending through the insulation material to lead the defrosting water from the first cooler to the machine room; and a first drain pipe extending through the insulation material to lead the defrosting water from the second cooler to the machinery room. a second drain pipe leading to the drain pipe, a water storage part installed on the ceiling wall of the machine room to create a water level into which the tips of both drain pipes are immersed, and a collective member consisting of a water guide part extending from the top of the water storage part to above the evaporating dish. It is something.

(E) Effect According to the present invention, since the first drain pipe and the second drain pipe are submerged in the water storage part, no air circulation occurs, and
There is no need to lead both drain pipes onto the evaporating dish.

(F) Embodiments Next, embodiments will be explained with reference to the drawings. FIG. 1 shows a longitudinal cross-sectional view of the cooling storage 1 of the present invention, and FIG. 2 shows the doors 4 and 5 of the freezing room 2 as the first storage room, the ice room 3 as the second storage room, and the quenching. A perspective view of the cooling storage 1 excluding the inner door 7 of the chamber 6 is shown. Reference numeral 8 denotes an insulating box body that opens to the front and is filled with a heat insulating material 47. The inside of the box is divided into upper and lower sections by a partition wall 9, with a freezer compartment 2 at the top that is cooled to freezing temperature and a freezer compartment 2 at the bottom that is cooled to 0°C. An ice chamber 3 is formed which is maintained at a freezing storage temperature of about -5°C. The quenching chamber 6 is formed at the upper left corner of the freezing chamber 2 by a vertical partition 10 and a horizontal partition 11. A heat insulating board 12 is attached to the back of the ice chamber 3 with a gap between them, and this gap is used as the cooling chamber 13.
A cooler 14 for the icehouse is vertically installed here.
Reference numeral 15 denotes a blower for the icehouse placed above the cooler 14 for the icehouse. The blower 15 for the icehouse is a propeller fan, which rotates and blows the cooler 14 for the icehouse.
The cold air that has exchanged heat with the cold air is accelerated, discharged from the front discharge port 16 into the ice room 3, and sucked through the suction port 17 at the lower end of the heat insulating plate 12. Reference numeral 18 designates a second refrigerant circuit, which includes a second compressor 20 installed in a machine room 19 formed at the bottom of the cooling storage 1, an evaporation condenser 21 in front of the second compressor 20, and a main condenser disposed in the insulation box 8. 22, a pressure reducer 23 and an icehouse cooler 14 are successively connected to each other.

A heat insulating plate 25 is attached to the back surface of the freezer compartment 2 with a gap therebetween, and this gap is used as a cooling chamber 26, and a freezer compartment cooler 27 is installed vertically therein. A freezer compartment blower 29 constituted by a propeller fan is disposed in the cooler 26 above the freezer compartment cooler 27.
In addition, a discharge port 30 with a relatively large opening area is bored in the upper left part of the heat insulating board 25 located in front of this, corresponding to the back of the quenching chamber 6, and a discharge port 30 with a relatively large opening area is bored in the part other than the part of the quenching chamber 6 on the right side. Discharge ports 31 with relatively small opening areas are provided in parallel at positions corresponding to the freezing chambers 2 . 32 is a suction port formed at the lower end of the heat insulating plate 25. Further, 33 is a first refrigerant circuit, which is installed in the machine room 19 similarly to the compressor 20.
A compressor 34, an evaporation compressor 42, a main condenser 35 disposed in a heat insulating box 8, a pressure reducer 36, and a freezer cooler 27 are connected in sequence. The freezer compartment blower 29 rotates to accelerate the cold air that has exchanged heat with the freezer compartment cooler 27, discharges it from the front discharge ports 30 and 31 into the quenching compartment 6 and the freezer compartment 2, and sucks it from the suction port 32. It is. The first refrigerant circuit 33 is filled with a refrigerant having a boiling point lower than that of the second refrigerant circuit 18, and the evaporation condenser 42 is placed above the evaporation condenser 21.

An evaporation plate 38 is placed on the evaporation condenser 42 . Furthermore, a dew pan 39 is arranged below the cooler 14 for the icehouse, and a drain pipe 40 for the icehouse extends downward from the dew pan 39 inside the back wall insulating material 47 of the heat insulating box 8 to connect the machine room 19. Its tip is exposed to the inside of the machine room 19 from the top wall 19A. Further, from below the cooling room 26, a drain pipe 46 for the freezing room extends downward inside the back wall insulation material 47, and its tip is connected to the machine room 19 from the ceiling wall 19A near the drain pipe 40 for the ice room.
It is open to the inside. Both drain pipes 40, 46
Further, the tip of the assembly member 4 provided on the lower surface of the ceiling wall 19A
9 is inserted into the water storage section 50.

FIG. 3 is a longitudinal sectional view of the heat insulating box 8 of the gathering member 49 portion, and FIG. 4 is a perspective view of the gathering member 49. The gathering member 49 has a container-shaped water storage portion 50 that opens upward.
A water guide portion 51 is integrally formed in the center of the water storage portion 50 and opens to the upper part of the water storage portion 50 and extends downward from there. Drain pipe 4 on ceiling wall 19A
There is a machine room 19 around the lead-out parts 52 and 53 of 0 and 46.
A claw 54 protruding inward is formed, and a flange 50A on the upper edge of the water storage portion 50 is engaged with the claw 54, so that the gathering member 49 is attached to the ceiling wall 19A. In this state, the ends of both drain pipes 40 and 46 are inserted into the lower part of the water storage part 50 on both sides of the upper end of the water guide part 51 as shown by the arrows in FIG. The plate 38 is opened upward.

Freezer room cooler 27 or ice room cooler 14
The defrosting water flows down through the drain pipe 46 for the freezing room or the drain pipe 40 for the freezing room, respectively, and flows into the collecting member 49.
The defrosting water W flows into the water storage section 50 and is temporarily stored therein, and when the water surface of the defrosting water W reaches the upper end of the water guide section 51, it flows into the water guide section 51 and is discharged into the evaporation tray 38. As a result, a water level L is formed in the water storage portion 50, and both drain pipes 40 and 46 are immersed below the water level L. Therefore, the drain pipes 40 and 46 do not communicate with each other, and the cold air in the freezing chamber 2 and the cold air in the freezing chamber 3 do not mix with each other, and the odor in the freezing chamber 3 does not mix with the ice in the freezing chamber 2. It does not transfer to. In addition, low-temperature cold air in the freezer compartment 2 does not flow into the ice room 3 due to the operation of the blower 15 and cause supercooling, and
The comparatively high-temperature cold air in the ice room 3 is sucked by the operation of the blower 29 and does not flow into the freezing chamber 2 and adversely affect the freezing capacity. Furthermore, since the gathering member 49 is attached to the ceiling wall 19A of the machine room 19,
If the ends of the drain pipes 40 and 46 face the machine room, they can be easily inserted into the water storage part 50 and assembly is easy. Also, since it is not necessary to lead both the drain pipes 40 and 46 to the evaporating dish 38, manufacturing work efficiency is improved. It also improves. Furthermore, the water level L in the water storage section 50 prevents outside air from flowing into the drain pipes 40 and 46 from the water guide section 51.

In the embodiment, the second storage room is an ice room, but the second storage room is not limited to this, and may be used as a normal refrigerator room.

(g) Effects of the invention Since the invention is constructed as described above, the cold air in the first storage chamber and the cold air in the second storage chamber do not mix with each other via the defrosting water drain pipe. Therefore, independent temperature control of both storage compartments is possible,
Further, it is also possible to prevent the odor in the second storage chamber from transferring to the ice or the like in the first storage chamber. Furthermore, it has great practical effects, such as improving assembly workability.
