  In the refrigerator disclosed in Patent Document 1, it is desired that the cooling efficiency of food in the storage room can be improved while paying attention to the handling of the refrigerant piping so as not to interfere with surrounding components.

  The present invention has been made under such a background, and an object of the present invention is to provide a refrigerator capable of improving the cooling efficiency while preventing interference between a flow path for flowing a refrigerant and surrounding components.

  The present invention includes a main body in which a storage chamber for storing articles to be cooled and stored, a compressor provided in the main body for compressing a refrigerant, a cooler provided in the main body for evaporating the refrigerant, A flow path that is provided in the main body and circulates the refrigerant between the compressor and the cooler, a first mounting member to which the cooler is mounted, and the cool air around the cooler by being driven to rotate. A second mounting member to which the fan is mounted, wherein a space for disposing the cooler is formed between the fan to be fed into the storage chamber and the first mounting member so as to be opposed to the first mounting member; A protrusion provided on one attachment member, projecting toward the second attachment member, contacting the second attachment member, and disposed between a portion around the cooler in the flow path and the fan; It is characterized by including It is a storehouse warehouse.

  In the present invention, the cooler includes a pipe that extends while meandering and allows a refrigerant to flow. The cooler is provided on the first mounting member, and the pair of linear portions extending in parallel in the pipe is widened. And a first support portion inserted between the straight portions to support the pipe.

  In addition, the present invention includes a second support portion that is provided on the first attachment member and wraps and supports a curved portion that is curved so as to make a U-turn in the pipe.

  Moreover, this invention includes the defrost member which removes the frost adhering to the said cooler, and is provided in the said 1st attachment member, It has a through-hole by which the said defrost member is inserted from the longitudinal direction of the said defrost member. A ring-shaped third support portion is included.

  In the present invention, the main body includes an outer box constituting an outer shell of the main body, and an inner box housed in the outer box and having the storage chamber and the cooler therein. A side wall portion having a through hole, and a side wall portion attached to the side wall portion from the outside of the inner box, through the through hole and into the inner box. Covering the second mounting member from a side opposite to the first mounting member side, a stopper having a protruding convex portion, an engaging portion provided on the second mounting member and engaging the convex portion, And a cover member engaged with the convex portion.

According to the present invention, in the refrigerator, when the refrigerant flowing through the flow path and circulating between the compressor and the cooler evaporates in the cooler, the air around the cooler is cooled and becomes cold air. The cool air around the cooler is sent to the storage room by a fan to cool the articles in the storage room. The cooler is attached to the first attachment member, and the fan is attached to the second attachment member.
The second mounting member is disposed to face the first mounting member, and forms an arrangement space for the cooler between the second mounting member and the first mounting member. The protrusion provided on the first attachment member protrudes toward the second attachment member and contacts the second attachment member. Thereby, the dimension of the arrangement | positioning space in the opposing direction of a 1st attachment member and a 2nd attachment member is defined by the protrusion amount of a protrusion part. Therefore, if the size of the arrangement space in the facing direction is made as small as possible by reducing the protruding amount of the protruding portion, it is possible to prevent the useless space in which cool air stays on both sides of the cooler in the facing direction. As a result, since the cool air around the cooler arranged in the arrangement space can be sent to the storage room with almost no leakage and used for cooling the articles in the storage room, the cooling efficiency can be improved.

Support the pipe. Thus, if it is the structure which press-fits a 1st support part between adjacent pipes, since a pipe becomes difficult to remove | deviate from a 1st support part, the cooler containing a pipe can be firmly attached to a 1st attachment member. .

Moreover, according to this invention, the 2nd support part provided in the 1st attachment member wraps and supports the curved part curved so that it may make a U-turn in a pipe. Thereby, since a curved part becomes difficult to remove | deviate from a 2nd support part, the cooler containing a pipe can be firmly attached to a 1st attachment member.
In addition, since the curved portion is covered by the second support portion, it is possible to prevent the air that is desired to be guided to the straight portion to be cooled from passing through the curved portion side from being efficiently cooled. Therefore, since the air to be cooled can be effectively guided to the straight portion and cooled around the straight portion, the cooling efficiency can be further improved.

  Further, according to the present invention, the defrosting member is inserted in the through hole of the ring-shaped third support portion provided in the first mounting member from the longitudinal direction of the defrosting member so as not to be displaced. It can be firmly attached to one attachment member.

  Further, according to the present invention, in the configuration in which the first attachment member is attached to the side wall portion of the inner box of the main body and the cover member covers the second attachment member from the side opposite to the first attachment member side, It is attached to the side wall portion from the outside of the inner box, and the convex portion of the stopper protrudes into the inner box through the through hole of the side wall portion. If the engaging part provided in the 2nd attachment member is engaged with a convex part, and a cover member is engaged with a convex part, a 2nd attachment member and a cover member can be fixed to a side wall part. Thereby, even if it does not use many fastening members, such as a screw, a 2nd attachment member and a cover member can be fixed to a side wall part.

It is distinguished from the refrigerated inner box 16. A refrigerator compartment 4 </ b> A is formed inside the refrigerator compartment 15. The opening 13A of the refrigerated inner box 15 is the opening 8 of the refrigerator compartment 4A. An ice making room 4B, a variable temperature room 4C, a first freezing room 4D, and a second freezing room 4E are formed inside the freezing inner box 16. The opening 13A of the freezer inner box 16 is divided into the respective openings 8 of the ice making room 4B, the variable temperature chamber 4C, the first freezing room 4D, and the second freezing room 4E.

  A plate-like partition member 17 that is thin in the up-down direction Z and extends in the horizontal direction H and a plate-like partition member 18 that is thin in the left-right direction X and extends in the front-rear and up-down directions are provided in the freezer inner box 16. The partition member 17 is disposed between the ice making room 4B and the variable temperature room 4C and the first freezing room 4D in a state of being laid between both side walls in the left-right direction X of the freezing inner box 16. Thereby, the partition member 17 partitions between the ice making chamber 4B and the first freezing chamber 4D adjacent in the vertical direction Z, and between the variable temperature chamber 4C and the first freezing chamber 4D adjacent in the vertical direction Z. Partition (see FIG. 2). The partition member 18 is disposed between the ice making chamber 4B and the variable temperature chamber 4C in a state of being laid between the substantially central portion of the partition member 17 in the left-right direction X and the upper wall 16A of the freezer inner box 16. Thereby, the partition member 18 partitions between the ice making chamber 4B and the variable temperature chamber 4C which adjoin in the left-right direction X (refer FIG. 2). Further, a partition member 19 that partitions the first freezer compartment 4D and the second freezer compartment 4E is provided in the freezer inner box 16. A columnar partition member 21 elongated in the left-right direction X is provided at a position spaced from the partition member 19 to the front Y1 in the main body 2.

  The refrigerated inner box 15 and the frozen inner box 16 are arranged adjacent to each other in the vertical direction Z in the outer box 12. The lower wall 15A of the refrigerated inner box 15 is disposed in the upper Z1 with a gap with respect to the upper wall 16A of the frozen inner box 16. Between the front end portions of the lower wall 15A and the upper wall 16A, a plate-like connecting portion 20 extending in the left-right direction X is installed. Thereby, the refrigerated inner box 15 and the frozen inner box 16 are in a state of being connected to each other.

  The heat insulating member 14 is made of urethane, for example. When the main body 2 is manufactured, the foamable urethane foams after being injected into the gap between the outer box 12 and the inner box 13 or the gap between the refrigerated inner box 15 and the frozen inner box 16 and is filled in these gaps. Thus, the heat insulating member 14 is obtained.

The heat insulating member 14 is arranged in advance in each internal space when the partition members 17 and 18 are in the state of parts before being incorporated into the main body 2. Thus, the partition member 17 insulates the ice making chamber 4B and the variable temperature chamber 4C from the first freezing chamber 4D, and the partition member 18 insulates the ice making chamber 4B and the variable temperature chamber 4C. In addition, as the heat insulation member 14 in each of the partition members 17 and 18, a foamed polystyrene molded product can be used instead of foaming urethane. Moreover, the hatching (refer FIG. 5) which shows the cross section of the heat insulation member 14 is abbreviate | omitted in FIG. 4 for convenience of explanation.

  The refrigerator 1 generates cool air for cooling the articles in each storage chamber 4 by a vapor compression refrigeration circuit using a refrigerant such as isobutane. The refrigerator 1 includes a compressor 25, a flow path 26, a cooler 27, a condenser 29, a dryer 30 and the like that constitute the refrigeration circuit.

  As the compressor 25, a known component for compressing the refrigerant is used. The compressor 25 is disposed at the lower end of the rear Y2 of the main body 2. The flow path 26 is configured by, for example, a metal pipe, and is a circulation flow path that returns the refrigerant to the compressor 25 again after taking out the refrigerant from the compressor 25. The flow path 26 is disposed so as to go around the main body 2 and the partition member 17 as indicated by a dotted line in FIG. Specifically, the flow path 26 is stretched over the entire region of the heat insulating member 14 of the main body 2 and the partition member 17. The direction in which the refrigerant flows in the flow path 26 is indicated by a dotted arrow.

  The cooler 27 is also called an evaporator, and a known component is used for the cooler 27 as a component for evaporating the refrigerant. One cooler 27 is provided for each of the refrigerated inner box 15 and the frozen inner box 16. The cooler 27 of the refrigerated inner box 15 is hereinafter referred to as a first cooler 27A, and the cooler 27 of the refrigerated inner box 16 is hereinafter referred to as a second cooler 27B. The first cooler 27 </ b> A and the second cooler 27 </ b> B are provided in the middle of the flow path 26. The first cooler 27A is accommodated in, for example, a box-shaped first cooling chamber 31, and the second cooler 27B is accommodated in, for example, a box-shaped second cooling chamber 32. The first cooling chamber 31 is disposed in the refrigerated inner box 15. The first cooling chamber 31 has an outlet 31A and an inlet 31B, and the outlet 31A is provided with a fan 33 that is rotationally driven. The second cooling chamber 32 is disposed in the freezer inner box 16. The second cooling chamber 32 has an outlet 32A and an inlet 32B, and the outlet 32A is provided with a fan 34 that is rotationally driven.

  The condenser 29 is a component that condenses the refrigerant, and is provided between the compressor 25 and the cooler 27 in the flow path 26. The dryer 30 is a component that dries the refrigerant, and is provided between the condenser 29 and the cooler 27 in the flow path 26. A part of the flow path 26 between the dryer 30 and the cooler 27 is configured as a capillary tube.

  The refrigerant is compressed into a high-temperature and high-pressure gas refrigerant by being compressed by the compressor 25, and then liquefies while dissipating heat when passing through the condenser 29. The liquefied refrigerant is decompressed when passing through the dryer 30 and then through the capillary tube, and then evaporates in the first cooler 27A and the second cooler 27B. Incidentally, the flow path 26 is provided with a branch path 26A that is shortcutted to the second cooler 27B without passing through the first cooler 27A. Therefore, a part of the refrigerant decompressed by the capillary tube goes directly to the second cooler 27B through the branch path 26A as indicated by a dotted arrow A1.

  When the refrigerant evaporates in the first cooler 27A, the air around the first cooler 27A in the first cooling chamber 31 is cooled to become cool air. The cold air in the first cooling chamber 31 is pushed out of the first cooling chamber 31 from the outlet 31A by the rotating fan 33 and flows through the refrigerating chamber 4A of the refrigerating inner box 15 as indicated by the solid line arrow. It returns to the 1st cooling chamber 31 from 31B, and is cooled again by the 1st cooler 27A. While the fan 33 is rotating, the cold air circulates between the refrigerating room 4A and the first cooling room 31 to cool the articles in the refrigerating room 4A. In this way, the fan 33 is driven to rotate to feed the cool air around the first cooler 27A into the refrigerating chamber 4A.

  When the refrigerant evaporates in the second cooler 27B, the air around the second cooler 27B in the second cooling chamber 32 is cooled to become cool air. The cold air in the second cooling chamber 32 is pushed out of the second cooling chamber 32 from the outlet 32A by the rotating fan 34, and as shown by the one-dot chain line arrow, in the first freezing chamber 4D of the freezing inner box 16 Then, after flowing through the second freezing chamber 4E, it returns from the inlet 32B into the second cooling chamber 32 and is cooled again by the second cooler 27B. In this way, the fan 34 is driven to rotate to feed the cool air around the second cooler 27B into the first freezer compartment 4D and the second freezer compartment 4E. During the rotation of the fan 34, the cold air circulates between the first freezing chamber 4D and the second freezing chamber 4E and the second cooling chamber 32 to cool the articles in the first freezing chamber 4D and the second freezing chamber 4E. To do. Since the flow rate of the cold air in the freezer inner box 16 is set to be larger than the flow rate of the cold air in the refrigerating inner box 15, the articles in the freezer inner box 16 are stored frozen.

  Since the ice making room 4B (see FIG. 2) and the first freezing room 4D are always in communication, the cold air in the first freezing room 4D always flows into the ice making room 4B while the fan 34 is rotating. Thereby, the production | generation and preservation | save of ice in the ice making chamber 4B are implement | achieved.

  On the other hand, the variable temperature chamber 4C and the first freezer compartment 4D are in communication with each other through a through hole 17A penetrating the rear end of the partition member 17 in the vertical direction Z. The through hole 17A is a circuit called a damper. It is opened and closed by a movable plate-like opening and closing member 35. Therefore, when the opening / closing member 35 closes the through hole 17A in the posture along the horizontal direction H as shown by the solid line, the temperature between the variable temperature chamber 4C and the first freezing room 4D is blocked, so the first freezing room The cold air in 4D does not flow into the temperature changing room 4C. On the other hand, in the state where the opening / closing member 35 is rotated upward Z1 and the through hole 17A is opened as shown by the dotted line, the temperature changing chamber 4C and the first freezer compartment 4D communicate with each other. As shown by the two-dot chain line arrow, the cold air flows through the through-hole 17A and flows into the variable temperature chamber 4C to cool the articles in the variable temperature chamber 4C. When the opening / closing time of the opening / closing member 35 is changed to adjust the opening degree of the through hole 17A, the flow rate of the cold air from the through hole 17A toward the variable temperature chamber 4C is adjusted. Thereby, the room temperature of the variable temperature room 4C can be set arbitrarily.

  As described above, the refrigerant evaporated in the first cooler 27 </ b> A and the second cooler 27 </ b> B continues to flow through the flow path 26, returns to the compressor 25, and is compressed again by the compressor 25. That is, the refrigerant repeats compression, heat dissipation, decompression, and evaporation while circulating between the compressor 25 and the cooler 27 by flowing in the flow path 26.

  Since the second cooler 27 </ b> B of the second cooling chamber 32 generates cold air for freezing, frost can be generated on the surface of the second freezer 28. Therefore, the second cooling chamber 32 is provided with a defrost heater 36 as a defrosting member for removing frost attached to the surface of the second refrigerator 28. When the defrost heater 36 is energized and generates heat, the frost on the surface of the second cooler 27B melts and flows down as water. For example, an evaporating dish 37 opened to the upper side Z <b> 1 is provided at the lower end of the main body 2. The water that has flowed down from the surface of the second cooler 27 </ b> B accumulates in the evaporating dish 37 through a water channel 38 (see FIG. 5) that extends from the second cooling chamber 32 to the lower Z <b> 2 and is connected to the evaporating dish 37. The water accumulated in the evaporating dish 37 evaporates due to the refrigerant that has become high temperature by the compressor 25 and the heat of the flow path 26. A defrost heater (not shown) having the same function as the defrost heater 36 is also provided in the first cooling chamber 31.

  Referring to FIG. 6, which is a block diagram showing the electrical configuration of the refrigerator 1, the refrigerator 1 includes a fan drive motor 41 and a damper in addition to the compressor 25 and the defrosting heater 36 described above as the above-described electrical components. A switching motor 42 and a temperature sensor 43 are included. The fan drive motor 41 is provided in each of the fans 33 and 34, and rotates the corresponding fan. The damper switching motor 42 opens and closes the opening / closing member 35. The temperature sensor 43 is provided in each storage chamber 4 and detects the room temperature of the corresponding storage chamber 4. The control unit 11 is electrically connected to these electrical components, controls the operation of the compressor 25, the defrost heater 36, the fan drive motor 41 and the damper switching motor 42, and inputs the detection result of the temperature sensor 43. Or accept.

  The above is the outline of the refrigerator 1, and the configuration of the cooler 27 and its periphery will be described in detail below. In the following description, among the coolers 27, the second cooler 27B disposed in the refrigerated inner box 16 will be described. However, the following configuration also applies to the first cooler 27A disposed in the refrigerated inner box 15. Is possible.

  Referring to FIG. 7 which is a plan sectional view of the main body 2 of the refrigerator 1, the rear wall 16B which is a side wall portion constituting the rear Y2 side wall of the freezing inner box 16 is recessed from the front side surface to the rear Y2. A recess 16C is provided. The refrigerator 1 includes a cooling unit 50 that closes the recess 16C from the front Y1. Referring to FIG. 8, which is an exploded perspective view of the cooling unit 50, the cooling unit 50 includes the second cooler 27 </ b> B, a part of the flow path 26, the defrost heater 36, the first attachment member 51, and the like. The 2nd attachment member 52 and the cover member 53 are included.

  Referring to FIG. 9 which is a perspective view of the first mounting member 51, the second cooler 27B, and the defrost heater 36, the second cooler 27B includes a pair of left and right side plates 55, pipes 56, and fins 57. Including. The pair of side plates 55 is a plate shape that is thin in the left-right direction X and is long in the up-down direction Z, and is opposed to the left-right direction X with an interval.

  The pipe 56 is a part of the flow path 26. That is, the pipe 56 is a part constituting the second cooler 27 </ b> B in the flow path 26. Therefore, the refrigerant flowing through the flow path 26 also flows through the pipe 56. The pipe 56 extends downward Z2 while meandering so as to alternately pass through the pair of side plates 55, and then extends upward Z1 while meandering so as to alternately pass through the pair of side plates 55. Therefore, the pipe 56 includes a plurality of linear portions 56A that extend linearly along the left-right direction X, and a plurality of curved portions 56B that are curved to make a U-turn. There are twelve straight line portions 56A in total, for example, six rows in the upper and lower rows and two rows in the front and rear, and these straight line portions 56A are arranged in parallel. The curved portion 56 </ b> B is disposed outside the pair of side plates 55 in the left-right direction X. Each curved portion 56 </ b> B connects the left ends and the right ends of a pair of adjacent pipes 56.

There are as many sets of fins 57 that are overlapped in the left-right direction X as many as the upper and lower rows of the straight portion 55A of the pipe 56 (here, six). Each pair of fins 57 is in a state of being skewered by two linear portions 56A arranged in the front-rear direction.

  Low-temperature and low-pressure refrigerant flows through the pipe 56 of the second cooler 27B. At that time, heat is exchanged between the air around the straight portions 56A and the fins 57 and the refrigerant. As a result, the refrigerant in the pipe 56 evaporates, and this air is cooled to cool air.

  The defrost heater 36 is formed in a stick shape elongated in the left-right direction X. Electric wires 58 for supplying power to the defrost heater 36 are connected to both ends in the left-right direction X of the defrost heater 36.

A convex portion 61B that protrudes upward Z1 is provided at a position adjacent to the recess 61A from the rear Y2 on the upper surface portion of the first support portion 61. The depression 61A on the lower surface portion of the first support portion 61 penetrates the first support portion 61 in the left-right direction X while being depressed upward Z1. A convex portion 61B that protrudes downward Z2 is provided at a position adjacent to the recess 61A from the rear Y2 in the lower surface portion of the first support portion 61.

  One second support portion 62 is provided at each of the left end portion and the right end portion of the front surface portion of the first mounting member 51. Each of the second support portions 62 includes a substantially semi-cylindrical bag-shaped first portion 62A that bulges outward in the left-right direction X of the first mounting member 51, and the upper end portion of the first portion 62A to the outside. And a plate-like second portion 62B extending obliquely upward Z1. The internal space 62C of the first portion 62A is formed in a substantially semi-cylindrical shape similar to the first portion 62A, and is opened toward the inner side in the left-right direction X of the first attachment member 51. The left and right second support portions 62 are disposed at midway positions in the vertical direction Z of the first mounting member 51, but the positions in the vertical direction Z may not be the same. The second support portion 62 on the right side X2 is located below the first support portion 61 in the lower Z2.

  One third support portion 63 is provided at each lower end portion of the left end portion and the right end portion of the front surface portion of the first mounting member 51. Each of the third support portions 63 is thin in the left-right direction X, has a ring shape when viewed from the left-right direction X, and is provided to protrude from the front surface portion of the first mounting member 51 to the front Y1 and the lower Z2. The ring-shaped third support portion 63 is formed with a through hole 63A that is bordered by the inner edge thereof. The through hole 63A penetrates the third support part 63 in the left-right direction X.

  The first attachment member 51 is attached to the rear wall 16B from the front Y1 with a screw or the like in a state along the bottom 16D of the recess 16C of the rear wall 16B of the refrigerated inner box 16 (see FIG. 7). The second cooler 27 </ b> B and the defrost heater 36 are attached to the front surface portion of the first attachment member 51 from the front Y <b> 1. Referring to FIG. 10, which is a front view of the state in which the second cooler 27 </ b> B and the defrost heater 36 are attached to the first attachment member 51, in the first attachment member 51, the protruding portion 60 is the first in the flow path 26.

Referring to FIG. 11, which is a cross-sectional view taken along the line B-B in FIG. 10, among these pair of straight portions 56 </ b> A, the straight portion 56 </ b> A of the upper Z1 The straight portion 56 </ b> A of the lower Z <b> 2 fits from the lower Z <b> 2 in the first support portion 61 from the lower Z <b> 2. In the first support portion 61, the convex portion 61B of the rear Y2 of each recess 61A is located at the rear Y2 of the straight portion 56A, so that the straight portion 56A is prevented from coming off from the recess 61A to the rear Y2.

  The first support portion 61 is in a state of being press-fitted between the pair of linear portions 56A so as to increase the vertical distance K between the pair of linear portions 56A. Thereby, the pipe 56 is supported by the first support portion 61. If the first support portion 61 is press-fitted between the adjacent pipes 56 in this way, the pipe 56 is unlikely to be detached from the first support portion 61, so the cooler 27 including the pipe 56 is connected to the first mounting member 51. The position of the cooler 27 after the attachment can be stabilized. Therefore, after the cooler 27 is attached to the first attachment member 51, the pipe 56 is connected to the first support portion 61 in the operation of welding the third portion 26 </ b> D (see FIG. 10) of the flow passage 26 to the other flow passage 26. It can be prevented from coming off. Further, the pipe 56 can be connected to the first support portion 61 by an easy operation of simply press-fitting the first support portion 61 between the pair of linear portions 56A.

  Referring to FIG. 10, in the first mounting member 51, the left and right curved portions 56 </ b> B of the pipe 56 of the second cooler 27 </ b> B are provided one by one in the internal space 62 </ b> C of the first portion 62 </ b> A of the left and right second support portions 62.

Accordingly, the curved portion 56 </ b> B is unlikely to be detached from the second support portion 62, so that the cooler 27 including the pipe 56 can be firmly attached to the first attachment member 51.

  In addition, since the curved portion 56B is covered by the second support portion 62, the air to be guided to the straight portion 56A for cooling from now on, the curved portion 56B side, more specifically, the concave portion 16C of the rear wall 16B of the freezer inner box 16 and the second Passing through the left and right gaps 64 (see FIG. 13 to be described later) with the two coolers 27B can be prevented from being efficiently cooled. Incidentally, the gap 64 is a portion unnecessary for heat exchange in the second cooler 27B. Therefore, since the air to be cooled can be effectively guided to the straight portion 56A and cooled around the straight portion 56A, the cooling efficiency can be further improved.

  Moreover, in each 2nd support part 62, the 2nd part 62B opposes the curved part 56B located right above from the lower Z2, and this curved part 56B is prevented from shifting | deviating to the downward Z2.

  In the defrost heater 36, the left end portion is inserted into the through hole 63 </ b> A of the third support portion 63 on the left side X <b> 1 in the first mounting member 51 from the right side X <b> 2 in the left-right direction X that is the longitudinal direction of the defrost heater 36. . Similarly, the right end portion of the defrost heater 36 is inserted from the left side X1 in the left-right direction X into the through hole 63A of the third support portion 63 on the right side X2 in the first mounting member 51. Thereby, the defrost heater 36 is supported by these 3rd support parts 63 in the state constructed between the 3rd support parts 63 on either side, and is firmly attached to the 1st attachment member 51 so that it may not shift | deviate up and down and back and forth.

FIGS. 12A and 12B are perspective views of the stopper 66 viewed from different directions.

  The stopper 66 has a plate-like base portion 66A that is thin in the front-rear direction Y and long in the vertical direction Z, and a convex portion 66B that protrudes forward Y1 from the front side surface portion of the base portion 66A. The convex portion 66B is formed in a block shape that is long in the up-down direction Z, and is formed to become narrower to the left and right as it goes to the front Y1. In the middle of the convex portion 66B in the vertical direction Z, a through hole 66C that penetrates the convex portion 66B to the left and right is formed. 12B, both the base portion 66A and the convex portion 66B are cut at the same time along the front-rear direction Y on both sides of the through hole 66C in the vertical direction Z in the convex portion 66B with reference to the posture of the stopper 66 in FIG. One notch 66D is formed one by one. Inside each notch 66D, there is provided an engaging portion 66E that extends continuously from the base portion 66A to the front Y1 and then folded back to the right X2 to extend to the rear Y2. The engaging portion 66E is formed in a substantially V shape when viewed in the vertical direction Z, and can be elastically deformed so as to be closed or opened. In the case of FIG. 12B, the distal end portion 66F of the engaging portion 66E is the right end portion of the engaging portion 66E and is formed in a claw shape. The left side surface portion of the front end portion of the convex portion 66B in FIG. 12A is a flat contact portion 66G along the up and down direction.

  Referring to FIG. 13, which is a front view of the lower part of the main body 2 of the refrigerator 1, in the rear wall 16 </ b> B of the freezing inner box 16, two through holes 16 </ b> E are arranged vertically on both sides of the recess 16 </ b> C in the left-right direction X. Formed one by one. In this embodiment, there are a total of four through holes 16E, and each through hole 16E is formed in a slit shape elongated in the vertical direction Z. The above-described stoppers 66 are used in the same number as the through holes 16E, and are attached to the rear wall 16B from the rear Y2 that is the outside of the freezing inner box 16. The projection 66B of the corresponding stopper 66 is passed from the rear Y2 to each through hole 16E, and the projection 66B protrudes from the rear Y2 into the inside of the freezing inner box 16.

  In each stopper 66, the distal end portion 66F of the engaging portion 66E is disposed so as to face the concave portion 16C of the rear wall 16B of the freezing inner box 16. Therefore, in the stopper 66 on the left side X1 from the recessed portion 16C, the distal end portion 66F of the engaging portion 66E faces the right side X2, and in the stopper 66 on the right side X2 from the recessed portion 16C, the distal end portion of the engaging portion 66E. 66F is facing left X1. In each stopper 66, the base portion 66A engages with the peripheral portion of the through hole 16E in the rear wall 16B from the rear Y2, and the tip portion 66F of the engaging portion 66E engages with the peripheral portion from the front Y1. At the same time, it is engaged from either side in the left-right direction X (see also FIG. 14 described later). Thereby, the stopper 66 is fixed to the rear wall 16B so as not to be detached.

  As shown in FIG. 8, the unitized second cooler 27B, defrost heater 36, and first attachment member 51 are accommodated in the recess 16C of the rear wall 16B, as shown in FIG. The attachment member 52 and the cover member 53 are attached to the first attachment member 51 and the rear wall 16B from the front Y1 in this order. FIG. 7 shows a state where the attachment of the second attachment member 52 and the cover member 53 is completed. Referring to FIG. 7, in the second mounting member 52, the main body portion 52 </ b> A is in a state of being opposed to the first mounting member 51 from the front Y <b> 1, and the cover member 53 is on the first mounting member 51 side. The main body 52A of the second mounting member 52 is covered from the front Y1 opposite to the rear Y2.

  Referring to FIG. 14, which is an enlarged view of a main part surrounded by a broken-line square in FIG. 7, there are two engaging portions 52 </ b> F provided at both left and right edges of the main body portion 52 </ b> A of the second mounting member 52. Each of the stoppers 66 is engaged with the convex portion 66B by being fitted one by one from the inside in the left-right direction X into the through hole 66C of the convex portion 66B. Further, the left and right engaging portions 53E in the main body portion 53A of the cover member 53 are from the outside in the left-right direction X with respect to the contact portions 66G of the convex portions 66B of the two upper and lower stoppers 66 at the same position in the left-right direction X By contacting, it is in a state of being engaged with the convex portion 66B.

  Thus, the second attachment member 52 and the cover member 53 are fixed to the rear wall 16B. Accordingly, the second mounting member 52 and the cover member 53 can be fixed to the rear wall 16B without using many fastening members such as screws. Thereafter, when the screw 65 (see FIG. 8) is assembled into the recess 53C of the cover member 53 from the front Y1, the cooling unit 50 is completed. The positions of the second attachment member 52 and the cover member 53 are stabilized by the stopper 66, and the insertion hole 53D at the bottom of the recess 53C and the insertion hole 52E at the front end of the protrusion 52D of the second attachment member 52 are not displaced. Since they are overlapped, the screws 65 can be easily inserted into these insertion holes (see FIG. 16 described later). The engaging portions 52F other than the engaging portion 52F engaged with the stopper 66 in the main body portion 52A are engaged with engaging holes 53F provided in the upper end edge and the left and right end edges of the main body portion 53A of the cover member 53. Therefore, the second mounting member 52 and the cover member 53 are fixed to each other (see FIG. 8).

  Referring to FIG. 15, which is a right side view of a vertical section of the completed cooling unit 50, a first attachment member 51 and a main body portion of a second attachment member 52 that is disposed to face the first attachment member 51 from the front Y1. 52A constitutes a part of the second cooling chamber 32 (see FIG. 4) described above. Specifically, the first attachment member 51 constitutes the rear side wall of the second cooling chamber 32, and the main body 52 </ b> A constitutes the front side wall of the second cooling chamber 32. In the recess 16C of the rear wall 16B, portions other than the bottom 16D constitute upper, lower, left and right side walls of the second cooling chamber 32 (see FIG. 13).

  An arrangement space 70 in which the second cooler 27 </ b> B and the defrost heater 36 are arranged is formed between the first attachment member 51 and the main body 52 </ b> A of the second attachment member 52. Referring to FIG. 16, which is an enlarged view of a main part surrounded by a broken-line square in FIG. 15, the protrusion 60 provided on the first mounting member 51 is directed substantially horizontally toward the main body 52 </ b> A of the front Y <b> 1. The front end of the protrusion 60 is fitted from the rear Y2 into the protrusion 52D of the main body 52A, and is in contact with the front end of the protrusion 52D from the rear Y2. Further, the bottom of the concave portion 53C of the main body portion 53A of the cover member 53 is in a state of being in contact with the front end portion of the protruding portion 52D from the front Y1. At this time, the screw hole 60B in the front end surface 60A of the protrusion 60, the insertion hole 53D in the bottom of the recess 53C, and the insertion hole 52E in the front end of the protrusion 52D overlap in the front-rear direction Y, and the screw 65 described above. Is assembled in the screw hole 60B through the insertion hole 52E and the insertion hole 53D. Thereby, the 1st attachment member 51, the 2nd attachment member 52, and the cover member 53 are integrated.

  In the configuration in which the protruding portion 60 of the first mounting member 51 protrudes toward the second mounting member 52 and contacts the second mounting member 52, the front-rear direction, which is the opposing direction of the first mounting member 51 and the second mounting member 52 The dimension Q of the arrangement space 70 in Y is determined by the protrusion amount of the protrusion 60, that is, the dimension of the protrusion 60 in the front-rear direction Y. Therefore, if the dimension Q of the arrangement space 70 in the front-rear direction Y is reduced as much as possible by reducing the protrusion amount of the protrusion 60, useless spaces in which cool air stays are generated on both sides of the second cooler 27B in the front-rear direction Y. Can be prevented. As a result, the cool air around the second cooler 27B arranged in the arrangement space 70 can be sent to the storage chamber 4 with almost no leakage and used for cooling the articles in the storage chamber 4, thereby improving the cooling efficiency. I can plan.

Since the second portion 26C of the flow path 26 is located below the projecting portion 60 Z2 and the fan 34 is located above the projecting portion 60 Z1, the projecting portion 60 is located between the second portion 26C and the fan 34. It is in a state of being placed. Thereby, since the movement of the second portion 26C to the upper Z1 is suppressed, it is possible to prevent interference between the flow path 26 and the fan 34, which is a component around it.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.

  For example, the fixture 75 for attaching the temperature sensor 43 described above to the main body 2 may be provided as a single component as shown in FIG. Referring also to FIG. 18, which is an exploded perspective view of temperature sensor 43 and fixture 75, fixture 75 includes a main body portion 76 and a seal member 77. The main body portion 76 includes a substantially rectangular plate-shaped base portion 78 and a semi-cylindrical storage portion 79 provided so as to bulge from one side surface 78A of the base portion 78. The body portion 76 is provided with a recess 76A that is recessed from the other side surface 78B of the base portion 78 to the inside of the storage portion 79, and the temperature sensor 43 is stored in the recess 76A. Two claw-like engaging portions 78C are provided, for example, on both sides of the recess 76A on the side surface 78B. A plurality of intake ports 80 for taking in the cold air to be detected are formed on the curved surface of the storage unit 79, and these intake ports 80 communicate with the recess 76A. The seal member 77 has a plate shape, is attached so as to be in surface contact with the side surface 78B of the base portion 78, and closes the recess 76A from the side surface 78B side. Note that a part of the recess 76 </ b> A may not be blocked by the seal member 77, and the wiring 44 of the temperature sensor 43 may be drawn out from this part.

  The attachment 75 is attached to the inner box 13 of the main body 2 with the intake port 80 facing the inside of the storage chamber 4. When the engaging portion 78 </ b> C is engaged with the inner box 13, the fixture 75 is fixed to the inner box 13. Accordingly, the seal member 77 is securely sandwiched between the base portion 78 of the main body portion 76 and the inner box 13, so that the seal member 77 is not peeled off from the main body portion 76 and maintains a state where the concave portion 76 </ b> A is closed. . This prevents erroneous detection of the temperature sensor 43 due to air that is not a detection target flowing into the recess 76A from the side surface 78B of the base portion 78, and the temperature sensor 43 can accurately detect the room temperature in the storage chamber 4.

  The fixture 75 and the temperature sensor 43 accommodated in the recess 76 </ b> A constitute a sensor unit 81. The sensor unit 81 may be attached to the second attachment member 52 described above in order to detect the room temperature of the first freezer compartment 4D and the second freezer compartment 4E (see FIG. 8). As shown in FIG. 19, as another example, the sensor unit 81 may be attached to the refrigerating chamber duct 82 that partitions the refrigerating inner box 15 from the rear Y2 as indicated by broken line arrows. The refrigerator compartment duct 82 is a part constituting the front wall of the first cooling chamber 31 (see FIG. 4) described above, and the fan 33 is attached to the refrigerator compartment duct 82. As yet another example, the sensor unit 81 may be provided on the lower surface of the partition member 17 as shown in FIG. 20 to detect the room temperature in the first freezer compartment 4D.

  The refrigerator 1 may also include an interior lamp 100 that lights up when the door 3 is opened. The interior lamp 100 is connected to the control unit 11 (see FIG. 6), and the control unit 11 controls lighting, extinction, illuminance, luminance, and the like of the interior lamp 100. The interior lamp 100 is provided, for example, over the entire front surface portion of the refrigerator compartment duct 82 (see FIG. 5). In this case, when the door 3 is opened and the interior lamp 100 is turned on, the illuminance in the refrigerator compartment 4A is improved and the appearance in the refrigerator compartment 4A is also improved. In addition, if it is set as the structure which raises the brightness | luminance of the interior lamp 100 when it lights up in several seconds, the appearance in the refrigerator compartment 4A can be improved further. Such an interior lamp 100 may be provided in all the storage rooms 4 other than the refrigerator compartment 4A. In this case, the interior lamp 100 in each storage chamber 4 is disposed on the lower surface of each of the upper wall 16A, the partition member 17, and the partition member 21 of the freezer inner box 16 so as to illuminate the target storage chamber 4 from above Z1.
