Detailed ways

The first invention is characterized in that it includes: a main box with heat insulation performance; a partition body that partitions the above-mentioned main box up and down to form storage rooms with different temperature zones; A door which can be opened and closed separately; and a suppression part formed by the structure of the partition which suppresses the heat intrusion into at least one said storage chamber.

Accordingly, it is possible to provide a refrigerator capable of suppressing heat intrusion from the outside of the box and heat exchange between storage rooms in different temperature ranges, and reducing power consumption.

It is also possible to further include: a metal abutting member arranged on the door-side front surface of the partition body; a gasket arranged between the abutting member and the door to improve the airtightness of the storage room, and the suppressing The portion is disposed at least one of above and below the contact member.

Thereby, it is possible to provide a refrigerator capable of suppressing the intrusion of heat into the box from the above-mentioned metal contact member in contact with the outside air and reducing power consumption.

In addition, the shape of the box outer side of the said suppressing part may be rectangular.

Thereby, it is possible to suppress a decrease in overall appearance quality at the time of door opening, which is caused by the front surface portion of the partition constituting the space being conspicuous from surrounding structures.

In addition, the separator may have an upper partition, a lower partition, and vertical fitting portions for fixing the upper partition and the lower partition in the vertical direction.

Thereby, the up-and-down fitting after assembly of the components which comprise a space can be ensured, and it can achieve ensuring heat insulation performance and improving an external appearance quality.

In addition, the separator may have an upper partition, a lower partition, and front and rear fitting portions for fixing the upper partition and the lower partition in the front-rear direction.

Thereby, the front-rear fit after assembly of the components constituting the space can be ensured, and it is possible to ensure heat insulation performance and improve appearance quality.

In addition, the said suppressing part may have a foam heat insulating material inside by filling.

Thereby, the refrigerator which has the suppressing part with a high energy-saving effect can be provided.

In addition, the separator may have air holes communicating the internal space and the outside.

As a result, since the fluidity of the heat insulating foam material flowing into the space is ensured, the heat insulating foam material can be reliably filled in the entire space, and mass production of refrigerators with high energy-saving effects can be stably carried out. It is possible to suppress the deviation of each product.

Moreover, the said partition body may have the heat insulating material storage space which accommodates the excess foam heat insulating material in the periphery of the said air hole.

Thereby, by making the overflowed heat insulating foam material actively flow into places that are difficult to see from the outside, it is possible to suppress a decrease in appearance quality due to leakage of the heat insulating foam material on the exterior side or in the storage compartment.

In addition, the suppressing portion may form a closed space at a junction between the partition body and the main case.

This forms a space where gas does not convect between the storage rooms in different temperature ranges, and the air flowing in the gap between the partition body and the main box acts as an obstacle, thereby suppressing mutual heat intrusion between the storage rooms.

It may also have: an inner box hole, which communicates with the inner space of the above-mentioned separator and the inner space of the main box on the surface where the above-mentioned separator is in contact with the main box; When the foam heat insulating material is filled inside, it is filled in the inside of the said separator via the said inner tank hole.

Thereby, the foam heat insulating material flowing in from the inner box acts as an obstacle to the air flowing in the gap, and the heat insulating effect is further improved, so that the heat intrusion can be suppressed.

Furthermore, the suppressing portion may be formed by a rib which is a plate-shaped rib which abuts against the inner surface of the main case to form a space, and which protrudes from the peripheral edge of the partition.

Thereby, a space can be easily configured, and a complex shape can be configured, so that heat intrusion can be suppressed in various shapes.

In addition, the suppressing portion may form a closed space inside the separator.

Thereby, in the shape of the inner surface of the main case, a closed space can be formed in a part that cannot be formed, so that the suppression of heat intrusion can be improved.

The suppression part may form a plurality of closed spaces.

Thereby, the resistance due to the obstacle becomes larger with respect to the air flowing in the gap, and the effect of suppressing the intrusion of heat can be enhanced.

In addition, the above-mentioned suppressing portion may be provided with a convex shape protruding toward the separator side in a part of the inner case.

Accordingly, since the gap between the partition body and the inner box can be partially closed, the movement of the air flowing in the gap can be prevented, and thus the mutual heat intrusion suppression effect between the storage compartments can be enhanced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In some cases, the same structures as those in conventional examples or previously described embodiments will be given the same reference numerals, and detailed descriptions thereof will be omitted. In addition, this invention is not limited to this embodiment.

As shown in Figure 1, the main box 101 of the refrigerator 100 includes an outer box 102 mainly made of steel plates and an inner box 103 molded with resin such as ABS, and between the outer box 102 and the inner box 103 is filled with, for example, rigid polyurethane foam, etc. Foam insulation. Refrigerator 100 is mainly insulated from surroundings by main cabinet 101 . The main box 101 is divided into a plurality of storage compartments. Refrigerator 104 is arranged as a storage room at the uppermost part of main cabinet 101, vegetable room 105 is arranged as a storage room at the lower part of this refrigerator room 104, and freezer room 106 is arranged as a storage room at the lowermost part.

The front openings of the storage compartments are closed by doors 117 , 118 , and 119 so that opening and closing is possible.

Refrigerating room 104 sets the temperature that does not freeze to the lower limit for cold storage, and usually sets it in the range of 1°C to 5°C. Vegetable compartment 105 is set at a temperature equal to or slightly higher than that of refrigerator compartment 104, and is usually set within a range of 2°C to 7°C. The freezer compartment 106 is set in a freezing temperature range for cryopreservation, and is usually set in a range of -22°C to -15°C. In addition, the freezer compartment 106 may be set at a low temperature of, for example, -30°C or -25°C in order to improve the cryopreservation state. In addition, although the vegetable compartment 105 can also switch the temperature range to the freezer compartment and set it to -18 degreeC, it demonstrates as a vegetable compartment in this following description.

A machine compartment 107 is provided in the area behind the freezer compartment 106 at the lowermost portion of the main cabinet 101 . High-pressure-side components of the refrigeration cycle, such as a compressor 108 and a dryer (not shown) for removing moisture, are housed in the machine compartment 107 .

As shown in FIG. 2 , a cooling room 109 for generating cold air is provided on the back of the freezing room 106 . Between the freezer compartment 106 and the cooling compartment 109, an inner partition wall 110 having heat insulation properties is provided. The inner partition wall 110 forms a conveyance air path for conveying cold air to each chamber, and is used for thermally insulating and partitioning each chamber. A cooler 111 is arranged in the cooling chamber 109 . The upper space of cooler 111 is equipped with cooling fan 112 that sends the cold air cooled by cooler 111 into refrigerator compartment 104 , vegetable compartment 105 , and freezer compartment 106 by forced convection. In the lower space of the cooler 111, a glass-tube radiant heater 113 for removing frost and ice adhering to the cooler 111 and its periphery during cooling is provided. Furthermore, a drain receiving pan 114 for receiving defrosted water generated during defrosting and discharging it out of the box is provided under the radiation heater 113, and an evaporating pan 116 is provided outside the box on the downstream side.

Inner partition wall 110 is provided with outlet 115 for guiding cold air generated by cooler 111 to freezer compartment 106 by cooling fan 112 and inlet 117 for returning cold air circulating in freezer compartment 106 to cooler 111 .

Moreover, the storage box 126 which stores foodstuffs is arrange|positioned in the freezer compartment 106. As shown in FIG. The storage box 126 is drawn together with the drawer.

As shown in FIG. 3A, the end part of the inner surface of the door 119 is provided with the gasket 121 over the whole circumference (it is the same in the refrigerator compartment 104 and the vegetable compartment 105). Gasket 12 prevents cold air inside freezer compartment 106 and vegetable compartment 105 from leaking to the outside by being in close contact with metal contact member 123 provided on the front surface of divider 122 . Here, partition body 122 is formed of resin as a member that partitions vegetable compartment 105 and freezer compartment 106 up and down.

Furthermore, in the separator 122 , the suppressing portion 124 is formed in the vicinity of the contact member 123 (downward in the case of the present embodiment). Suppressing portion 124 is a portion of partition 122 for preventing contact member 123 from directly contacting the internal spaces of vegetable compartment 105 and freezer compartment 106 , and suppresses temperature rise in vegetable compartment 105 and freezer compartment 106 by heat conduction. Among the suppressing parts that suppress heat intrusion in this way, the suppressing part 124 is a heat conduction suppressing part that suppresses heat conduction that occurs when objects, that is, solid objects abut against each other.

In addition, a heat radiation pipe 131 is disposed on a portion of the separator 122 that is in contact with the back surface of the contact member 123 . The heat radiation pipe 131 is a pipe body for preventing dew condensation on the contact member 123 which is the front part of the partition body 122, and the heat radiation pipe 131 circulates high-temperature refrigerant in a refrigeration cycle (not shown) inside. Therefore, the contact member 123 is heated by heat exchange with the high-temperature refrigerant, and the occurrence of dew condensation is suppressed.

As shown in FIGS. 4 and 5 , the suppression portion 124 is located below the contact member 123 and is provided over the entire width direction of the separator 122 . In addition, openings 128 are provided at both ends in the width direction of the suppressing portion 124 . The opening 128 has a protrusion shape protruding outward in the width direction, and is inserted into an insertion hole 127 provided at a portion corresponding to both side walls of the inner case 103 . By inserting the opening portion 128 into the main case 101 as described above, the front portion of the partition body 122 is fixed to the main case 101 .

As shown in FIG. 6 , a heat insulating material 134 is arranged inside the case of the heat radiation pipe 131 arranged on the back surface of the contact member 123 . The heat insulator 134 suppresses the intrusion of heat from the heat radiation pipe 131 through the partition body 122 into the case. Furthermore, the suppressing part 124 provided in the lower part of the contact member 123 is filled with the foam heat insulating material 130. As shown in FIG. Thereby, the heat insulation efficiency of the suppressing part 124 is improved, and the direct intrusion of heat from the contact member 123 into the box is suppressed.

In addition, the separator 122 has, in addition to the opening 128 , an air hole 132 that communicates the inside and outside of the suppressing portion 124 , thereby improving the fluidity of the foam heat insulating material 130 filled through the opening 128 on the side surface of the separator 122 . , the foamed heat insulating material 130 is reliably filled in the suppressing part 124 as a whole, and heat insulation is ensured. The air hole 132 is provided toward the back side of the refrigerator 100 from the suppressing part 124, and the partition body 122 also has a foam heat insulating material storage space 133 on the back side of the air hole 132, so as to prevent the foam heat insulating material 130 from entering the exterior side and the storage room. side overflow.

As shown in FIG. 7, the partition body 122 has the upper partition board 135 and the lower partition board 136, and is formed by combining the upper partition board 135 and the lower partition board 136 up and down. In addition, the suppressing portion 124 is also constituted by an upper partition plate 135 and a lower partition plate 136 . The partition body 122 suppresses the heat exchange between the upper and lower storage compartments in different temperature ranges by interposing the heat insulating member 137 between the upper partition plate 135 and the lower partition plate 136 .

As shown in FIG. 8 and FIG. 9 , the upper partition plate 135 has a convex portion 140 , and by fitting into a concave portion 142 of the lower partition plate 136 , position regulation in the front-rear direction of the upper and lower partition plates is performed. Through the fitting of the convex part 140 and the concave part 142, it is possible to ensure the appearance quality and suppress the outflow of the foamed heat insulating material. In addition, by fitting the claw portion 141 provided on the upper partition plate 135 and the recessed portion 143 provided on the lower partition plate 136, the position of the upper and lower partition plates in the vertical direction is restricted, ensuring the appearance quality and suppressing foaming partitions. Hot material flows out.

The operation and function of the refrigerator configured as above will be described below.

First, the flow of cool air in freezer compartment 106 will be described. Cooled air cooled by cooler 111 is forcibly blown out from outlet 115 to the upper, middle, and lower sections of freezer compartment 106 by cooling fan 112 that rotates with the rotation of the motor. The blown cold air is sprayed to the storage box 126 to cool the stored food. The cold air for cooling food, as shown by the arrow, is inhaled by the suction port 117 through the gap between the storage box 126 and the bottom wall of the inner box, and returns to the cooler 111 in the air path structure.

As described above, when the cold air circulates in the freezer compartment 106, it is heated by exchanging heat with relatively high-temperature parts such as wall surfaces. The contact member 123 heated by the radiating pipe 131 has a high temperature relative to the cold air, but by providing the restraining portion 124 under the contact member 123, the direct contact between the contact member 123 and the cold air is avoided. Thereby, heating of cold air can be suppressed, and cooling efficiency can be improved, and as a result, power consumption can be reduced.

In addition, since the cold air can be suppressed from being heated and the cold air circulates at a low temperature, the temperature distribution in the entire freezer compartment 106 can be kept uniform.

Moreover, by providing the suppressing part 124 at the lower part of the contact member 123, the contact of the packing 121 and cold air can be reduced, and the heat exchange via the packing 121 can be suppressed. Furthermore, since the packing 121 suppresses the contact with the cold air which becomes high temperature by contacting the contact member 123, the heat exchange suppression effect can be further improved. In order to exhibit this effect, it is preferable that the step difference in the front-rear direction between the contact member 123 and the separator front surface portion 122a is 5 mm or less. If the above-mentioned level difference becomes large, it becomes difficult to close the space between the spacer 121 and the separator front surface portion 122 a in terms of the flexibility of the spacer 121 , and the effect of suppressing heat exchange decreases.

Through the above effects, the contact member 123 is cooled by exchanging heat with the cold air, and the sharp temperature difference between the inside and outside can also prevent dew condensation on the contact surface of the contact member 123 and the outside of the box.

In addition, by filling the suppressing portion 124 provided under the abutment member 123 with the foam heat insulating material 130 having high heat insulating efficiency, heat exchange from the radiation pipe to the surface in contact with the cool air can be further suppressed.

The partition body 122 is comprised by the upper partition board 135, the lower partition board 136, and the assembly heat insulating member 137 sandwiched between this upper and lower partition body.

The separator 122 has a convex opening 128 on both side surfaces of the suppressing portion 124 , and the convex opening 128 is inserted and fixed into an insertion hole 127 provided in the inner case 103 . Since the partition body 122 has the convex opening 128 , the opening 128 can protrude from the inner case 103 toward the outer case 102 , so that the suppressing part 124 can be easily filled with the heat insulating foam material 130 . Therefore, the fillability of the heat insulating foam material 130 in the suppression part 124 can be improved. In addition, by setting the gap between the convex opening 128 and the insertion hole 127 to be 1 mm or less, the foam insulation material 130 flowing in from the opening 128 is prevented from leaking into the storage room of the refrigerator and impairing the quality of the inside of the box. By fixing the convex opening 128 to the insertion hole 127, the front-rear positional relationship between the partition body 122 and the inner box 103 is determined, so that the front-back position of the partition body 122 can also be regulated.

Since the foamed heat insulating material 130 injected from the openings 128 at both ends of the suppressing part 124 has the property that it is difficult to flow in a closed space, by having an air hole 132 in the center of the suppressing part 124 for releasing the air in the space, The heat insulating foam material 130 can be reliably filled into the suppressing portion 124 . In the present embodiment, the air hole 132 is provided at one center, but it may be provided at a place other than the center or at multiple places according to the flow state of the heat insulating foam material 130 . Since the heat insulating foam material 130 filled in the suppressing portion 124 leaks to the outside from the void existing in the suppressing portion 124 , there is a high possibility of leaking through the pores 132 . Then, by providing the heat insulating foam storage space 133 capable of storing the leaked heat insulating foam 130 on the side of the storage compartment of the air hole, the heat insulating foam 130 having a volume equal to or greater than the volume of the inflow suppressing portion 124 is positively released. It flows into the foam heat insulating material storage space 133, and it suppresses that the foam heat insulation material 130 leaks to the appearance side or the storeroom side, and reduces the appearance quality.

Moreover, in the process of filling the heat insulating foam material 130 between the outer case 102 and the inner case 103, by also filling the suppressing part 124, it is possible to reduce man-hours and the number of parts.

In addition, in the upper partition plate 135 and the lower partition plate 136 constituting the suppressing portion 124, the upper partition plate 135 is provided with a convex portion 140 and a claw portion 141 for fitting respectively, and the lower partition plate is provided with a concave portion 142, 143. This is because in this specification, in order to minimize the amount of material used without increasing the number of parts, the suppressing portion 124 is composed of only the upper partition plate 135 and the lower partition plate 136, thereby suppressing the assembly of the upper and lower partition plates. A gap between components is generated in the restraining portion 124 during this time. By fitting the convex portion 140 provided on the upper partition plate and the concave portion 142 provided on the lower partition plate, the upper and lower partitions are suppressed from being squeezed by the foaming pressure when filling the foam heat insulating material 130 into the suppressing portion 124 . The plate creates a gap between the two members, and prevents the metal abutment member 123 from pressing against the front side due to the deformation of the separator front surface portion 122a on the appearance side, thereby preventing deterioration of the appearance quality due to deformation. Furthermore, by fitting the claw portion 141 provided on the upper partition plate and the concave portion 143 provided on the lower partition plate, similarly to the above, the occurrence of a gap between the members of the upper and lower partition plates constituting the suppressing portion 124 is suppressed, and the The foaming pressure deforms downward.

Furthermore, in the deformation caused by the foaming pressure of the upper and lower partition plates constituting the suppressing part 124, the partition body 122 constituting the suppressing part 124 is pressed from the front by the foaming jig together with the improvement of the strength of the member, and further Press also from below with the movable jig. Thereby, leakage of foam heat insulating material 130 to the appearance side or deformation of separator 122 constituting suppressing portion 124 due to foaming pressure can be suppressed, thereby ensuring appearance quality.

By making the exterior shape of the partition body front surface portion 122a on the exterior side of the partition body 122 constituting the suppressing portion 124 of the present invention rectangular, it has a sense of unity with surrounding members such as the contact member 123 and the inner box 103 . This is for not impairing the appearance quality when the periphery of the separator is exposed when the door 119 is opened, and for exerting the effect of suppressing heat exchange after the door is closed. In addition, in the appearance design of the separator front surface portion 122a, the rectangular shape is considered to be the best looking, but depending on the shape of peripheral parts, etc., as long as the shape other than the rectangular shape such as a curved shape has a sense of unity as a whole and looks good, it is also acceptable. Other configurations are conceivable.

In addition, the heat insulating member 137 is sandwiched between the upper and lower partition plates in the partition body 122, but instead of the heat insulating member 137, a heat insulating effect may be obtained by filling a foam heat insulating material.

As mentioned above, the refrigerator 100 of this Embodiment uses the partition body 122 to divide the inside of the main cabinet 101 up and down into a plurality of storage rooms supplied with cold air. The front surface of each store room has the door which can be opened and closed. The door has a gasket 121 in close contact with a metal abutment member 123 formed on the door-side front surface of the partition body 122 .

In this refrigerator 100, it has a structure which heats contact member 123 and pad 121, and is provided with the suppression part 124 which suppresses heat exchange between the cold air in a storage room, and contact member 123. The heat insulating material can be arranged between the contact member 123 and the storage room by the suppressing part 124, so the heat transfer to the contact surface of the contact member 123 which becomes high temperature due to the heat radiation pipe 131 and the cold air is transferred, and the thermal conductivity of the gap is low. The temperature of the surface in contact with cold air can be prevented from rising, and heat exchange can be suppressed. Thereby, heating of cold air can be suppressed, and cooling efficiency can be improved, and as a result, power consumption can be reduced.

In addition, as shown in FIG. 3A , the suppressing portion 124 may be arranged not only above or below the contact member 123 but also above and below the contact member 123 as shown in FIG. 3B .

As shown in FIG. 10, the inner surface of the door 119 is provided with a gasket 121 over the entire periphery (the same applies to the refrigerator compartment 104 and the vegetable compartment 105). Partition body 122 is made of resin and partitions vegetable compartment 105 and freezer compartment 106 up and down. In addition, a metal contact member 123 is provided on the front surface of the divider 122 , and the storage compartment is hermetically sealed by the contact member 123 and the packing 121 being in close contact.

In addition, a heat radiation pipe 131 is disposed on the back of the contact member 123 .

Furthermore, the suppressing part 124 which consists of the spacer 122 is formed under the contact member 123 via the spacer 122. As shown in FIG.
