The present invention relates to a refrigerator having a freezer storage space and a cold storage space, and having a cooler for cooling them and a cold air circulation fan.

In recent years, as shown in the longitudinal cross-sectional view of Fig. 17, the most frequent and large-capacity refrigerating chamber 55 is arranged at the top, and the ice making chamber 56 and the temperature switching chamber (not shown) are juxtaposed at the bottom thereof. Moreover, the type which arrange | positions the freezer compartment 59 in the lower part is provided with the vegetable compartment 58 which is the same refrigeration space as the refrigerating compartment 55, and accommodates vegetables.

On the back of the refrigerating chamber 55, a refrigerating cooler 63 and a fan 65 for cooling the refrigerating space are arranged, and the ice making chamber 56 and the ice cream chamber 56 are located at a position corresponding to the distribution of the vegetable chamber 58 below. A refrigeration cooler 64 and a fan 66 for cooling a freezing space such as a freezing chamber 59 are provided, and the refrigerant from the compressor 82 installed in the machine room at the lower part of the main body is provided for the refrigerating and The cold air generated by alternately flowing into the freezing coolers 63 and 64 and cooling each to a predetermined temperature was circulated through the respective storage spaces by the fans 65 and 66.

Since the refrigerating and freezing coolers 63 and 64 are cooled at a low temperature near -13 ° C or -30 ° C, respectively, it is necessary to reliably insulate the outside air, thereby improving the storage volume efficiency of the storage compartment with respect to the external shape. In order to increase, heat insulation performance was improved by arrange | positioning the vacuum insulation panel 70 of predetermined thickness as disclosed in Unexamined-Japanese-Patent No. 2005-69448 in the heat insulation wall 54 which consists of foam insulation materials, such as urethane foam normally. .

In addition, the refrigerating chamber 55 closes the front opening with a rotating door, and the vegetable chamber 58, the ice making chamber 56, the temperature conversion chamber, and the freezing chamber 59 are pulled forward by the pull-out door, the container, and the rail. I'm trying to.

The refrigeration and freezing coolers 63 and 64 are cooled to low temperatures around -13 ° C or -30 ° C, respectively, so that the coolers 63 and 64 need to be properly shielded from each cooler and the high outside and the inside of the storage compartment. The thickness of the heat insulation wall between the inner side and the outer side becomes thick, and there is a problem that the food storage volume in the storage compartment with respect to the outer shape becomes smaller.

On the other hand, in order to increase the storage volume efficiency in a storage chamber, the vacuum insulation panel 70 of predetermined thickness with high heat insulation performance is arrange | positioned in the heat insulation wall 54 which consists of foam insulation materials, such as urethane foam normally, and makes the heat insulation wall thickness thinner. As a result, the storage volume was increased (see Japanese Patent Laid-Open No. 2005-69448).

However, the vacuum insulation panel 70 is very expensive compared to the foam insulation, and as in the conventional refrigerator, the refrigerator cooler 63 and the refrigerator cooler 64 each have a refrigerator compartment 55 at the top of the body and a lower portion thereof. When arranged in the state of spaced up and down on the back of the vegetable chamber 58, the vacuum insulation panel 70 must be installed so as to cover at least the entire back surface in order to cover both coolers 63 and 64. There was a problem that the manufacturing cost increases due to the increase. In addition, when the upper and lower sides are arranged separately, the vacuum insulation panel becomes two parts, which is more expensive, and the cost increases inevitably in view of increasing the number of complicated manufacturing assembly steps.

On the other hand, as shown in FIG. 18, since the refrigeration cooler 64 of a lower temperature is arrange | positioned at the distribution of the said vegetable chamber 58 with a high set temperature, the temperature influence by the heat leakage resulting from the big temperature difference between them is reduced. In order to prevent it from being received, the front cover 68 having a thick heat insulation thickness is provided on the indoor side, and the heat insulation wall 54 on the outdoor side is also combined to increase the heat insulation thickness, thereby reducing the storage volume in the refrigerator.

In addition, the vacuum insulation panel 70 is very expensive compared to the foam insulation, and the problem is not solved only by installing it. Especially, in the refrigerating chamber 55 requiring a large capacity, a cooler disposed at the rear of the room is provided. Due to the thickness occupied by (63) and the heat insulator, the entire rear wall surface combined with the duct became an ineffective volume and still greatly reduced the effective volume for storing food.

On the other hand, since the refrigeration cooler 64 of lower temperature is arrange | positioned in the distribution of the vegetable chamber 58 with high set temperature, a thicker heat insulating material is installed in the room side so that it may not be influenced by the thermal leakage caused by the large temperature difference between them. In addition, since the heat insulation wall 54 of the outdoor side is also added and the heat insulation thickness becomes thick, there existed a fault which reduces the storage volume in the inside by that much.

The present invention has been made in view of the above circumstances, and by arranging the freezing and refrigerating coolers in accordance with the positions of the freezing or refrigerating storage space or the heat insulation wall, the effective thickness reduction is achieved, and the volume of the high internal storage space is increased accordingly. It is an object to provide a refrigerator which can be increased.

In addition, the present invention has been made in consideration of the above circumstances, by arranging the refrigerating and freezing chillers, cooling fans, cooling ducts, etc. in consideration of the location of the cooling storage space or the heat insulation wall, to achieve compactness and insulation thickness and duct An object of the present invention is to provide a refrigerator capable of effectively increasing the volume of an indoor storage space by arranging the space effectively.

In order to solve the above problems, the present invention provides a freezing and refrigerating cooler for cooling the freezing storage space and the refrigerating storage space, respectively, and a refrigerator provided with a fan for circulating cold air in each cooling space, the distribution of the storage space At least a part of the above-mentioned freezing and refrigerating coolers provided in close proximity to each other so as to overlap in the front-rear direction.

In addition, in order to solve the above problems, the present invention provides a refrigerating and freezing cooler for cooling each of the refrigerated storage space and the freezing storage space, which are insulated with a plurality of independent rooms, and a fan for circulating cold air in each cooling space. The refrigerator is characterized in that the refrigerator and the freezer for cooling, each fan and the duct are unitized and installed on the rear surface of a plurality of storage compartments partitioned up and down by a heat insulating wall.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described based on drawing. In addition, the same code | symbol is attached | subjected to the same component throughout the whole figure. 1 is a longitudinal sectional view of the refrigerator, and FIG. 2 is a front view thereof, wherein the refrigerator main body is formed of a heat insulating box made of an outer box 2 and an inner box 3 and a heat insulating material 4 filled in a space between these inner and outer boxes. The inside of (1) as a storage space is provided with the refrigerating chamber 5 at the uppermost part, the ice-making chamber 6 equipped with the automatic ice-making machine 6 and the temperature conversion chamber 7 below the heat insulating partition wall 10 below, and below these, In the vegetable chamber 8 and the lowermost part, the freezing chamber 9 is arrange | positioned independently, respectively. An insulating partition wall 10 is also provided between the vegetable chamber 8 and the freezing chamber 9, and a dedicated door is provided at the front opening of each storage chamber to open and close freely.

However, in the distribution of the vegetable compartment 8 located below the central part of the main body, there is a refrigeration refrigerator 13 for cooling the refrigerating compartment 5 or the refrigerating storage space 11 of the vegetable compartment 8, and the ice making chamber 6 and the temperature. The freezer cooler 14 which cools the freezer storage space 12, such as the switching chamber 7 and the freezing chamber 9, is arrange | positioned so that it may overlap back and front with respect to the depth direction, and is arrange | positioned so that it may shift to the left and right slightly.

As shown in Fig. 3, each of the storage chambers is formed from a compressor 22, a condenser 23, and a three-way valve 24 serving as a switching device for the refrigerant flow path, which are installed in the machine chamber 20 formed on the lower rear surface of the main body. The first throttle device 25 is formed by connecting the first throttle device 25 and the refrigeration cooler 13 on the high temperature side in series and returning to the compressor 22. And the second throttle device 26, the refrigeration cooler 14 on the low temperature side, the accumulator 27, and the check valve 28 in order, in parallel with the refrigerating side circuit composed of the cooler 13 on the high temperature side. It is cooled by the refrigeration cycle 21 which connected the connected refrigeration side circuit.

And the refrigerating side which consists of the 1st throttle device 25 and the refrigeration cooler 13 by the said three-way valve 24 by the detection temperature of the temperature sensor which is not shown in the refrigerator compartment 5 or the freezer compartment 8 etc. Cooling operation is performed by supplying a refrigerant by alternately switching a flow path to a freezing circuit including a circuit or a second throttle device 26, a freezing cooler 14, an accumulator 27, and a non-return valve 28. At the same time, the refrigerating storage space of the refrigerating compartment 5 or the vegetable compartment 8 on the high temperature side is rotated by the rotation of the fans 15 and 16 disposed in the vicinity of the refrigerating cooler 13 and the refrigerating cooler 14, respectively. 11) and each of the freezer storage spaces 12 such as the freezing chamber 9 and the ice making chamber 6 on the low temperature side are independently cooled and controlled to a predetermined temperature.

Each of the coolers 13 and 14 is installed exclusively for a freezing storage space and a cold storage space, and evaporation as close as possible to the corresponding storage temperature of -13 ° C for refrigeration and -30 ° C for freezing. By setting it as temperature, energy efficiency operation | movement is performed by keeping refrigeration cycle efficiency high.

Specifically, as shown in the perspective view of FIG. 4, the refrigeration cooler 13 at the high temperature side is provided at the vegetable chamber 8 side at the front side, and the refrigeration cooler 14 at the low temperature side is installed at the rear side. And the refrigeration coolers 13 and 14 juxtapose back and forth through the insulating cover 17 formed of a molded insulating material such as foamed styrol, respectively, to form independent cold air ducts, and the front side of the front refrigeration cooler 13 is It is integrated with the cooler unit 19 by covering it with the front cover 18 with relatively low heat insulation thickness. In addition, when the temperature difference between the refrigeration cooler 13 and a storage chamber, for example, the vegetable compartment 8 is very small, the said front cover may be formed with the sheet board about the synthetic resin panel board, not the cover body which consists of what is called a heat insulation body.

And above each of the coolers 13 and 14, fan 15, 16, Bellemouth, etc. which eject and circulate the cold air generated by the cooler in each storage space are provided, and together with the cooler unit 19, The integrated body is installed on the inner side of the rear heat insulation wall of the main body, and the front surface is covered with the air cover 30 to supply the cool air from the cooler to each storage space 11 and 12 by a refrigeration cycle operation. Each is cooled to a predetermined temperature.

At this time, the cold air discharged from the fan 16 is divided into upper and lower parts in the insulating cover 17 disposed between the refrigerating coolers 13 at the front of the refrigerating cooler 14 located at the rear side. The discharge duct 31 sent to the upper ice-making chamber 6, the temperature switching chamber 7, and the lower freezing chamber 9 is formed. In addition, a return duct or freezing chamber 9 from the ice making chamber 6 or the temperature conversion chamber 7 to the freezing cooler 14 is provided in a space formed on one side (the left side in FIG. 2) of the refrigerating cooling machine 13 located in front. Return duct 32 from the refrigerator or the return duct 33 for returning the cold circulated from the refrigerating chamber 5 to the vegetable chamber 8 and circulated to the refrigerating cooler 13, and the like. ), The fan 15 is arranged above and connected to the cold air jet duct 34 formed on the rear surface of the refrigerating chamber 5.

The cold air discharged from the freezer cooler 14 by the fan 16 is classified into an upper portion of the lowermost freezing chamber 9 by the discharge duct 31, and one side of the cold air blown upward is an ice making chamber 6. ) To promote ice making and to enter the temperature conversion chamber (7) through the damper (35) to control the cooling of the room to a predetermined set temperature. The return duct 32 returns to the cooler 14 again.

The cool air generated in the refrigerating cooler 13 is discharged into the cold air jet duct 34 by the fan 15 and is blown into the refrigerating chamber 5 from the cold air jet 36 provided up and down on the duct 34. The indoor storage is cooled, introduced into the vegetable compartment 8 through the duct from the lower suction port and cooled, and then circulated to return to the refrigerating cooler 13.

According to the above configuration, as shown in FIG. 5, which is a schematic longitudinal sectional view of the cooler installation portion, a difference in temperature almost occurs between the indoor refrigerator temperatures of all the refrigeration coolers 13 and the vegetable chamber 8 on the indoor side where the evaporation temperature is increased. Since it does not exist, the insulation thickness A, which is the size of the thickness of the front cover 18, which is a heat insulation partition wall for preventing water droplets or freezing, is clear as compared with FIG. In the case of a cooler and a vegetable compartment, the thickness can be remarkably thin, and the heat insulation thickness A which was 70 mm conventionally required as a in FIG. 18 is good also as 10 mm thickness.

In this case, in the configuration of the present invention, since the refrigerating and freezing coolers 13 and 14 are overlapped and installed, the new insulating cover 17, which is a new insulating cover 17, is required between the two coolers. On the other hand, since the rear surface of the refrigerating chamber 5 does not require a thermal insulation thickness d (10 mm) equivalent to the thermal insulation thickness a that was conventionally installed between the refrigerators for refrigerators 63, the thermal insulation thickness D is basically zero. In addition, since the heat insulation thickness E with the external air in the rear part of the refrigerating chamber 5 does not exist in the location, the heat insulation performance can be reduced and it becomes 10 mm thin and 40 mm.

Moreover, although the heat insulation thickness C of the back side of the main body of the cooling and freezing coolers 13 and 14 back surface is 70 mm which is the same conditions as the conventional case, as a total of the reduction amount by the above, about 55 mm heat insulation compared with a conventional structure The thickness can be reduced, and the high internal volume can be increased by about 22 L (liter) as compared with the conventional one under the same conditions in the state of maintaining the external size.

Next, another embodiment of the present invention will be described. In the said embodiment, although the cooler 13 and 14 juxtaposed back and forth were arrange | positioned on the back of the vegetable chamber 8, as shown in FIG. 6 described similarly to FIG. 5, in this embodiment, this is the back of the freezer compartment 9 And a refrigeration cooler (14) provided through the front cover (18 ') inside the freezer compartment on all sides, and the refrigeration cooler (13) is arranged via an insulating cover (17). will be.

In this case, the insulation thickness B '(25 mm), which is the insulation cover 17 between the freezing and refrigerating coolers 13 and 14, which are provided in front and rear, is the same as in the above embodiment, and the cooler on all sides has an evaporation temperature. Is a refrigeration cooler 14 having a low temperature, but since the corresponding indoor side is the freezing chamber 9 cooled to -18 ° C or lower, there is only a relatively small temperature difference between the two as in the above-described embodiment, so that heat leakage Insulation thickness A 'of the front cover 18' which cut | disconnects can be made into 10 mm similarly to the said Example, and can be made remarkably thin with respect to the insulation thickness a in the case of the conventional refrigeration cooler and a vegetable compartment.

In the case of the present embodiment, the rear side cooler is the refrigerating cooler 13, and since the temperature difference with the external air temperature is smaller than that of the freezer cooler, the insulation thickness C 'can be made thin. Insulation performance can be obtained by 50 mm, which is reduced by 20 mm compared with the above-described embodiment or the conventional example, and the total reduction amount can be reduced to the largest in the insulation thickness of 75 mm with respect to the conventional configuration shown in FIG. Compared with this, it can increase the internal volume by about 27 liters (liters).

In addition, as shown in FIG. 7, even when the refrigeration and refrigeration coolers arranged on the back of the vegetable compartment 8 are arranged so as to be the refrigeration cooler 14 and the refrigeration cooler 13 at the rear of the room. Since the evaporation temperature of the vegetable refrigerator 8 adjacent to the vegetable chamber 8 with a high setting room temperature is low, and the evaporation temperature of this part is low, the heat insulation thickness A ″ of the front cover 18 ″ of this portion is 70 mm as in the prior art. Although the thickness is required and the insulation thickness B ″ for insulation between the two coolers is equal to 25 mm as described above, the insulation thickness C ″ with the external air is determined by the fact that the rear cooler is the refrigerator cooler 13. 50 mm may be sufficient.

In addition, the heat insulation of the back side of the refrigerator compartment 5 side is not required similarly to each said Example, without requiring the heat insulation thickness d (10 mm) provided between the back surface of the refrigerator compartment 55 and the refrigerator cooler 63 conventionally. Since the cooling refrigerator 13 for the thickness E "does not exist in the place, heat insulation performance can be reduced and it can be made 10 mm thin and 40 mm, and as a total, the heat insulation thickness can be made 15 mm thinner compared with the former, and It can increase about 10L (liters) in volume.

According to each of the above embodiments, the refrigerating and freezing coolers 13 and 14 are juxtaposed back and forth corresponding to the storage compartment allocation, and the coolers located at all sides and the corresponding storage compartments are arranged in a small temperature difference so that the storage compartment and the refrigerating compartment Each cooler for refrigeration can be made into an optimal heat insulation relationship, and it becomes possible to reduce the thickness of the heat insulation layer inside a storage compartment and the outside of a main body, and can enlarge the volume of a storage space in the inside by that much, and also Since the cooler area corresponding to the upper and lower lengths becomes small, for example, even when a vacuum insulation panel is employed, the size to be installed can be minimized, thereby reducing the material cost and effectively installing it.

In addition, by integrally uniting the freezing and refrigerating coolers 14 and 13, the assembling work and transportation can be facilitated and the productivity and service work can be improved. In addition, the insulating cover member which forms the duct formed from molded heat insulating material, such as foamed plastic, unites the damper 34 which controls the refrigeration and refrigeration fans 16 and 15 or the cold air flow to each storage compartment, integrally. By integrating the units 19 of the freezing and refrigerating coolers, the arrangement of the components is integrated to obtain an energy saving effect.

Moreover, in the said embodiment, the layout of each storage chamber is arranged in the refrigerator compartment 5 at the top, next to the ice-making chamber 6 and the temperature switching chamber 7, and the vegetable chamber 8 in the lower part, and the refrigerator chamber 9 in the lower part. Although arrange | positioned as follows, this invention is not limited to this.

EMBODIMENT OF THE INVENTION Hereinafter, based on drawing, 4th Embodiment of this invention is described. 8 is a longitudinal sectional view of the refrigerator, and FIG. 9 is a front view thereof. In the following description, description of the same parts as in the first embodiment will be omitted to avoid duplication.

Since the refrigerating chamber 5 has the largest storage capacity and a high frequency of use, the opening is closed freely by pivotally supporting the Kannon-open door with hinges provided on both sides of the front opening, and the refrigerating chamber disposed below. The storage rooms such as the ice making chamber 6, the temperature changing chamber 7, the vegetable chamber 8, the freezing chamber 9, etc. other than (5) have a smaller storage volume than the refrigerating chamber, and the convenience of use due to the installation height position thereof. , The container held in the support frame fixed to the door is slid back and forth by the rail member provided on the interior wall surface, the door is drawn out to the outside with the door opening operation, and the drawer door method is used for storing and extracting food from the top opening of the container.

As shown in FIG. 3, the respective storage chambers are cooled by the refrigerating cycle 21 as in the first embodiment.

In this embodiment, as shown in FIG. 9 which is a cross-sectional view of the cooler part in the pretreatment step of foam-filling the heat insulating material 4 between the inner box 3 and the outer box 2, the refrigeration cooler 13 which is high temperature side is shown. ) Is on the front side of the vegetable chamber 8, and the refrigeration cooler 14 on the low temperature side is provided on the rear side, and these refrigeration and freezing coolers 13 and 14 are formed of a molded insulating material such as foamed plastic. It juxtaposes back and forth via the cover 17, and all the refrigeration coolers 13 are arrange | positioned so that it may shift to the left and right to the right side, and the rearward refrigeration cooler 14 to the left side.

FIG. 10 is a cross-sectional view of the cooling fans 15 and 16 corresponding to the rear surfaces of the ice making chamber 6 and the temperature switching chamber 7 above the FIG. 9 and filled with the foam insulation 4. And FIG. 11, which is a longitudinal cross-sectional view of the vicinity of the refrigeration cooler 14, and FIG. 12, which is a longitudinal cross-sectional view of the portion of the refrigeration cooler 13, the refrigeration cooler 13 in the front has a rear refrigeration. The fan 15 and the fan 16 are disposed in correspondence with the upper portions of the cooling and freezing coolers 13 and 14 while being positioned below the cooling cooler 14. And the low temperature cold air on the freezing side sucked up from the rear part of the fan 16 to the ejecting side, and part of the damper 118 to the front ice making chamber 6 and the temperature switching chamber 7, respectively. Is introduced through, and most of the other cold air is formed on the front surface of the refrigeration cooler (14) by the insulating cover (17). The freezing chamber is ejected to 9 in the downward direction from frozen blow-out duct 129 for controls cool the inside of each room to a predetermined temperature.

The cold air circulated through the ice making chamber 6 and the temperature switching chamber 7 passes through the I return duct 130 and the S return duct 131 formed in the heat insulation space on the left side of the refrigerating cooler 13 which is set to the right side. Then, it is led to the freezing suction port 132 below the freezing cooler 14, joins the freezer circulated in the freezing chamber 9, and returns to the freezing cooler 14.

The cooling on the side of the refrigerating space uses a duct extending from the top to the rear of the refrigerating cooler 13 installed on the right side as the suction duct 133 to the fan, and blows the cool air upward from the fan 15, and blows off the refrigeration. It flows in and rises into the back duct 135 formed widely from the duct 134 over the whole back surface of the refrigerating chamber 5, and it blows off in the room from the cooling outlet 136, such as an upper surface, a back center, and a back side edge part, It is cooled to a predetermined temperature.

The cold air circulated in the refrigerating chamber 5 is sucked into the refrigerating suction duct 137 which is installed to be inclined forward from the interior bottom to the whole of the refrigerating jet duct 134, and the insulation of the back of the temperature switching chamber 7 is insulated. The cold air introduced into the vegetable chamber 8 through the V duct 138 formed in the cover 17 and circulating-cooled in the vegetable chamber 8 is sucked into the lower part of the refrigerating cooler 13 from the bottom of the vegetable chamber. To repeat the cycle.

According to the above configuration, the cool air from the refrigerating cooler 13 is ejected upward from the position on the right side in the rear width direction in which the cooler is installed, on the same side, and flows into the back duct 135 and circulates in the refrigerating chamber 5. Afterwards, the V duct 138 flows to the vegetable chamber 8 formed in all of the refrigeration blow-out ducts 134 and all of the fan 15 suction portions. In an approximation, the thickness between adjacent ducts can be made thin and an effective duct structure can be obtained.

In addition, the refrigeration blowout duct 134 and the refrigeration suction duct 137 from the fan 15 to the rear duct 135 are the refrigerating chamber 5, the lower ice making chamber 6, and the rear part of the temperature conversion chamber 7. It is integrally installed in the molding insulation material 139 forming the partition wall, and the molding insulation material 139 is inserted into the partition wall part 10 from the distribution of the inner box 3 in the pretreatment step before the foam filling of the urethane foam insulation material. By attaching, the clearance of the partition wall 10 can be maintained reliably, the positioning of the ducts 134 and 137 is made easy, and it can be fixed to the inner box 3 reliably.

As described above, the refrigerating cooler 13 and the freezing cooler 14 are overlapped with each other on the rear surface of the vegetable chamber 8, and are arranged by shifting each side to the left and right. The temperature of the fan is minimized and the cooling fans 15 and 16 corresponding to the respective coolers are disposed in parallel with each of the coolers 13 and 14, and the fan 16 ejects the directions of the cooling air of each of the fans in the reverse direction. I'm going to squirt forward.

Therefore, the front side of the fan 16 and the refrigeration cooler 14 is equipped with a refrigeration blowout duct so that the cool air generated by the coolers 13 and 14 can flow in a good positional relationship to the corresponding cooling fans 15 and 16. 129 is formed and the refrigeration cooler 13 is installed through the insulating cover 17, so that the thickness of the heat insulating material of the insulating cover 17 can be reduced.

Moreover, the return ducts 130 and 131 from the ice-making chamber 6 and the temperature conversion chamber 7 are installed in the heat insulation wall by the side of the refrigeration cooler 13 installed in the front side, and are installed in other parts, such as an indoor side. It is possible to prevent the reduction of the storage compartment volume by

As shown in FIG. 13, which is an exploded perspective view of each component, the refrigeration cooler 13 and the refrigeration cooler 14 cover the front surface of the freezer cooler 14 or the freezing ever cover 141. The front surface of the refrigeration cooler 13 is covered with the refrigeration ever cover 142 through the insulating cover 17 to form an ever assembly 140, which is an ice making chamber 6, a temperature conversion chamber 7, and a vegetable chamber 8. It is attached to the piping of the space which comprises this, and it joins with the piping edge part of the said refrigeration cycle introduce | transduced into the room from outside the main body. At this time, as described above, since the front refrigeration cooler 13 is installed at a lower position than the rearward refrigeration cooler 14, pipe joining and welding of the upper part of the refrigeration cooler 14 can be easily performed. Can be.

And in this state, the Ever which installed each cold air suction inlet or blowout port shown by the exploded perspective view in FIG. 14, and the cold air duct to each chamber so that each cooling fan 15 and 16 may be located in the upper part of the coolers 13 and 14 in this state.
