冷蔵庫の開口側に垂直に温度調節器６を設置し、温度調節つまみ７を開口側に近づけ、温度調節器カバー４と内箱２との間にリード線５を通している。
【０００５】
【発明が解決しようとする課題】
従来の冷蔵庫では温度調節つまみ７の付く面の幅を狭めて低温保存室トレイ２６をできるだけ広くした場合、温度調節器カバー４の横幅は温度調節つまみ７を操作するために最低限必要な幅か、温度調節器６の幅により決まってくるため限界があった。
【０００６】
この発明は以上のような問題点を解決するためになされたもので、低温保存室側壁である温度調節器カバーの横幅が温度調節器や温度調節器つまみの大きさによらず低温保存室を広くすることが出来る冷蔵庫を得ることを目的とする。
【０００７】
また、貯水タンク保持器の横幅が小さく、冷蔵庫内が有効に活用できる冷蔵庫を得ることを目的とする。
【０００８】
また、凹形状カバーを取り付けた部分の外箱と内箱との間に配管を通さず、断熱幅が充分に確保され、発泡前の配管と内箱当たりが起こりづらくなる冷蔵庫を得ることを目的とする。
【０００９】
また、凹形状カバーと外箱との間に内箱を無くして断熱材の幅を広くして、成形圧力による凹形状カバーの変形を考えなくてすみ、断熱材により凹形状カバーが強固に固定される冷蔵庫を得ることを目的とする。
【００１０】
また、仕切りと凹形状カバーが一体に成形して部品点数が減り安価で、凹形状カバーを取り付ける作業がいらない冷蔵庫を得ることを目的とする。
【００１１】
また、リード線しか通っていなかった内箱と凹形状カバーとの間に電気部品を収納することにより無駄な空間を有効活用できる冷蔵庫を得ることを目的とする。
【００１２】
また、自動製氷機能がありながら低温保存室が広く活用できる冷蔵庫を得ることを目的とする。
【００１３】
また、自動製氷機能がありながら低温保存室が広く活用でき、凹形状カバーを内箱成形前に取り付けるため断熱材の漏れがなく、内箱の成形圧・発泡圧にも変形しにくい冷蔵庫を得ることを目的とする。

Further, by transmitting the heat of condensation of the pipe 14 to the outer case 1 via the aluminum tape 15, dew on the outer case 1 can be prevented.
In addition, since the concave portion is formed of a synthetic resin, deformation due to the molding pressure of the inner box 2 and the foaming pressure of the heat insulating material 27 can be prevented. There is no need for any tools, and it is inexpensive with no work steps and jig costs.
[0033]
Embodiment 2 FIG.

FIG. 6 is a sectional view of a main part of a refrigerator according to Embodiment 3 of the present invention. In the figure, the concave shape of the first embodiment is obtained by providing an opening 16 of the inner box 2 and attaching a concave concave cover 13 formed of a synthetic resin component to the opening 16 with a sealing material 17. is there.
[0034]
There is no inner box between the concave cover 13 and the outer box 1, and only the heat insulator is used. Thereby, the width of heat insulation can be widened.
[0035]
Embodiment 3 FIG.
Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 7 is a cross-sectional view of a main part of a refrigerator according to Embodiment 3 of the present invention. In the figure, the concave shape of the first embodiment is formed integrally with a partition 9 for partitioning the refrigerator 8.
[0036]
As a result, the cost is reduced as compared with the case where the concave cover is formed as a separate part, and the mounting work can be reduced.
[0037]
Embodiment 4 FIG.
Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a perspective view of a main part of a refrigerator according to a fourth embodiment of the present invention, and FIG. 9 is a sectional view of a main part of the refrigerator.
[0038]
9 is a refrigerator with an automatic ice making function, 8 is a refrigerator main body, 10 is a refrigerator room, 42 is a freezer room, 20 is a refrigerator room door that can open and close the refrigerator room 10, 43 is a refrigerator room door that can open and close the refrigerator room 42, Reference numeral 19 denotes a water storage tank for storing water, 44 denotes a water absorption pipe provided in the water storage tank 19 and erected in the supply water, 45 denotes a pump for sucking supply water from the water storage tank 19 through the water absorption pipe 44, and 46 denotes a pump discharged by the pump 45. A water supply pipe through which supply water passes, 47 is an ice tray for making the supply water discharged from the water supply pipe 46 into ice by the cool air in the freezing room 42, and 48 is an ice tray 47 for emptying the ice formed by the ice tray 47 downward. Is an ice storage case in which ice formed in the ice tray 47 falls and is stored.
[0039]
In FIG. 8, reference numeral 18 denotes a water storage tank holder disposed in the refrigerator compartment 10, and 19 denotes a water storage tank for automatic ice making. The water storage tank retainer 18 is integrally formed with the temperature controller cover shape 4a and the rail shape 12. Reference numeral 7 denotes a temperature control knob, which is formed on the inner box 2 side of the temperature controller cover 4a by the temperature controller and the concave shape described in the first embodiment. The cross-sectional structure is the same as that of FIG.
[0040]
The temperature controller cover shape 4a protrudes from the water storage tank retainer 18 toward the opening side of the inner box 2, and the temperature control knob 7 is provided at the opening side.
[0041]
The wall on the temperature controller side attached to the water storage tank holder 18 can be made thinner, and the storage space for food in the refrigerator can be widened. The temperature controller knob 7 approaches the opening side and is easy to operate. Since the water storage tank retainer 18 and the temperature controller cover 4 are integrally formed, the number of parts is small, the cost is low, and the mounting operation is easy.
[0042]
【The invention's effect】
The refrigerator according to the present invention has improved usability because the temperature controller is closer to the refrigerator compartment opening side, and the width of the temperature control cover, which is the side wall of the low-temperature storage room, does not depend on the size of the temperature controller or the like. Can be wider.
[0043]
Further, in the refrigerator according to the present invention, the width of the water storage tank retainer is reduced, and the inside of the refrigerator can be effectively used.
[0044]
Further, in the refrigerator according to the present invention, since the pipe does not pass between the outer box and the inner box in the portion where the concave cover is attached, a sufficient heat insulation width is secured, and the pipe and the inner box before foaming come into contact. It will not be difficult.
[0045]
Further, in the refrigerator according to the present invention, since the inner box is not provided between the concave cover and the outer box, the width of the heat insulating material is widened, so that the deformation of the concave cover due to the molding pressure does not need to be considered, and the heat insulating material is used. The shape cover is firmly fixed.
[0046]
Further, in the refrigerator according to the present invention, since the partition and the concave cover are integrally formed, the number of parts is reduced, the cost is low, and there is no need to attach the concave cover.
[0047]
Further, in the refrigerator according to the present invention, wasteful space is effectively utilized by storing electric components between the inner box through which only the lead wires pass and the concave cover.
[0048]
Further, the refrigerator according to the present invention can widely utilize a low-temperature storage room while having an automatic ice making function.
[0049]
In addition, the refrigerator according to the present invention has an automatic ice making function, and can be widely used in a low-temperature storage room. Since the concave cover is attached before the inner box is formed, there is no leakage of the heat insulating material. Is also difficult to deform.
[0051]
Further, the refrigerator according to the present invention has a small number of parts and is inexpensive, and the width of the temperature controller cover can be reduced, and the food storage space in the refrigerator can be expanded.
[0052]
In addition, the refrigerator according to the present invention has a small number of parts and is inexpensive, the temperature controller can be easily operated , the width of the temperature controller cover can be reduced, and the food storage space in the refrigerator can be expanded.
