[0036] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0037] The application provides a kind of refrigeration equipment, refrigeration equipment can be refrigerator, freezer.

[0038] Please refer to Figure 1 , Figure 1 It is the partial structure schematic view of the refrigeration equipment of the first embodiment of the utility model. The refrigeration equipment 10 includes the body 100, evaporator 200 and liquid accumulator 300. The body 100 is internally provided with storage chamber 101 and heat exchange chamber 102, and the evaporator 200 is arranged in the heat exchange chamber 102. The liquid accumulator 300 is connected with the evaporator 200. Generally, the refrigeration equipment 10 can also include a compressor, a condenser, a throttling element such as a capillary tube, since the working principle of the refrigeration system is well known to those skilled in the art, and will not be described here. The liquid accumulator 300 is a kind of gas-liquid separation piece, in the refrigeration circuit, the liquid accumulator 300 is arranged between the compressor and the evaporator 200, the refrigerant flowing from the evaporator 200 to the compressor is gas-liquid separated, the gaseous refrigerant therein flows into the compressor, and the unvaporized refrigerant liquid remains in the liquid accumulator 300, avoiding the liquid refrigerant from entering the compressor to affect the normal operation of the compressor.

[0039] In the related art, most of the evaporators of the current refrigerator are arranged vertically, and correspondingly, the liquid accumulator is installed in adaptation to the arrangement mode of the evaporator. When the evaporator is installed horizontally or obliquely in the heat exchange chamber, if the liquid accumulator is not treated in any way, the unvaporized refrigerant liquid in the evaporator can easily flow into the liquid accumulator and accumulate in the liquid accumulator in large quantities, so that the refrigerant cannot be fully evaporated, affecting the vaporization amount of the refrigerant and the refrigeration effect.

[0040] In the embodiments of the present application, please refer to Figure 1 and referenceFigure 2 , Figure 2 This is a schematic diagram of the connection structure between the evaporator and the liquid receiver according to an embodiment of the present invention. The liquid receiver 300 includes a first refrigerant inlet 320 and a second refrigerant outlet 330. It can be understood that the first refrigerant inlet 320 is the inlet end of the liquid receiver 300 (e.g., ...). Figure 1 (As shown at point A), the second refrigerant output terminal 330 is the outlet terminal of the liquid receiver 300. The evaporator 200 includes a first refrigerant output terminal 210 and a second refrigerant input terminal 220. The first refrigerant output terminal 210 is the output terminal of the evaporator 200 (e.g., ...). Figure 1 (As shown at point B), the second refrigerant input terminal 220 is the input terminal of the evaporator 200. The first refrigerant input terminal 320 of the receiver 300 is connected to the first refrigerant output terminal 210 of the evaporator 200 through the first connecting pipe 810. The second refrigerant input terminal 220 of the evaporator 200 is connected to the condenser through the second connecting pipe 820. The second refrigerant output terminal 330 of the receiver 300 is connected to the compressor through the return pipe 830.

[0041] The position of the first refrigerant input terminal 320 is higher than the position of the first refrigerant output terminal 210, such as Figure 1 As shown, point A is higher than point B, meaning the inlet of the receiver 300 is higher than the outlet of the evaporator 200. Therefore, if there is incompletely vaporized refrigerant liquid in the evaporator 200, because the outlet of the evaporator 200 is lower than the inlet of the receiver 300, the incompletely vaporized refrigerant liquid in the evaporator 200 is less likely to enter the receiver 300. This reduces the accumulation of refrigerant in liquid form in the receiver 300, ensuring sufficient evaporation in the evaporator 200 and allowing the refrigerant to fully participate in the refrigeration cycle, thus guaranteeing the evaporator 200's efficiency and improving the cooling effect. Furthermore, the reduced amount of refrigerant liquid entering the receiver 300 lowers the risk of refrigerant liquid entering the compressor, preventing liquid slugging and extending the compressor's lifespan.

[0042] In one embodiment, the storage chamber 101 and the heat exchange chamber 102 are arranged along the height direction of the bladder 100, that is, they are arranged along... Figure 1The heat exchange chamber 102 is arranged below the storage chamber 101 in the vertical direction. Specifically, a partition plate can be arranged inside the body 100, and the body 100 can be divided into the storage chamber 101 and the heat exchange chamber 102 by the partition plate. The storage chamber 101 is arranged above the partition plate, and the heat exchange chamber 102 is arranged below the partition plate. In a conventional refrigerator, the heat exchange chamber is generally formed between the freezing air duct and the rear wall of the body, and the heat exchange chamber and the storage chamber are arranged in front of and behind the depth direction of the body. In the embodiment, the heat exchange chamber 102 is arranged at the bottom of the storage chamber 101, and the heat exchange chamber 102 and the storage chamber 101 are arranged in the vertical direction of the height of the body 100. The length of the storage chamber 101 in the depth direction of the body 100 is increased, and the length of the storage drawer can be increased.

[0043] Correspondingly, the evaporator 200 can be designed as a flat cuboid, as shown in the drawings. Figure 1 The evaporator 200 can be arranged horizontally in the heat exchange chamber 102. Generally, the maximum size of the evaporator 200 is the size in the length or width direction, and the thickness size is generally the smallest. By arranging the evaporator 200 horizontally (compared with the vertical arrangement of the conventional evaporator), the thickness direction of the evaporator 200 is arranged in the vertical direction or at a small angle relative to the vertical direction, so that the height of the heat exchange chamber 102 is not increased.

[0044] In this way, when the evaporator 200 is arranged horizontally, the position of the first refrigerant input end 320 is higher than the position of the first refrigerant output end 210, and the inlet end of the liquid accumulator 300 is higher than the output end of the evaporator 200, which can effectively reduce the refrigerant liquid entering the liquid accumulator 300, so that the refrigerant can fully participate in the refrigeration cycle in the evaporator 200, ensure the working efficiency of the evaporator 200, and improve the refrigeration effect.

[0045] Please refer to Figure 2, the evaporator 200 includes an evaporating coil 201 made of multiple layers of evaporating tubes (not shown) coiled to form the evaporating coil 201, and the evaporating coil 201 is provided with the first refrigerant outlet 210 and the second refrigerant inlet 220. To further reduce the liquid refrigerant entering the liquid accumulator 300, in an embodiment, the first refrigerant inlet 320 is located higher than the highest point of the evaporating coil 201. It can be understood that when the evaporating coil 201 is provided with multiple layers, the first refrigerant outlet 210 can be located at the uppermost layer of the evaporating coil 201 or at the lowermost layer of the evaporating coil 201. In the present embodiment, no matter which layer the first refrigerant outlet 210 is located at, the first refrigerant inlet 320 of the liquid accumulator 300 is located higher than the highest point of the entire evaporating coil 201, which can greatly reduce the liquid refrigerant entering the liquid accumulator 300. For example, when the first refrigerant outlet 210 is located at the lowermost layer of the evaporating coil 201, at this time, the height difference between the first refrigerant inlet 320 and the first refrigerant outlet 210 is very large, and the liquid refrigerant is difficult to flow to the first refrigerant inlet 320, effectively reducing the liquid refrigerant entering the liquid accumulator 300.

[0046] In an embodiment, the second refrigerant inlet 220 is located lower than the first refrigerant outlet 210. That is, the input end of the evaporator 200 is lower than the output end of the evaporator 200, and in the opposite case, the output end of the evaporator 200 is higher than the input end of the evaporator 200. When there is unvaporized liquid refrigerant in the evaporating coil 201, the liquid refrigerant is more likely to stay in the evaporating coil 201 under the action of its own gravity rather than flowing to the liquid accumulator 300, until it is vaporized into refrigerant gas in the evaporating coil 201.

[0047] In an embodiment, the second refrigerant outlet 330 is located higher than the first refrigerant inlet 320, that is, the outlet end of the liquid accumulator 300 is located higher than the inlet end of the liquid accumulator 300. Then the liquid refrigerant entering the liquid accumulator 300 is also not easy to flow out through the outlet end of the liquid accumulator 300, further preventing the liquid refrigerant from entering the compressor through the return pipe 830, reducing the risk of liquid hammering.

[0048] Please refer to Figure 1 , the liquid accumulator 300 includes a tank body 310 provided with the first refrigerant inlet 320 and the second refrigerant outlet 330, and the axial direction of the tank body 310 is arranged along the height direction of the shell body 100, that is, the tank body 310 is arranged in the vertical direction. That is, in the case of transverse arrangement of the evaporator 200, the liquid accumulator 300 is arranged in the vertical direction.

[0049] By vertically arranging the liquid accumulator 300 instead of horizontally laying the liquid accumulator 300 together with the evaporator 200, on one hand, the non-gasified refrigerant liquid in the evaporator 200 is not easy to enter the liquid accumulator 300, further reducing the accumulation of refrigerant liquid in the liquid accumulator 300, on the other hand, the refrigerant liquid entering the liquid accumulator 300 is easy to flow back to the evaporator 200 to evaporate again, improving the evaporation amount, improving the efficiency of the evaporator 200, and improving the refrigeration effect. Moreover, the vertical arrangement of the liquid accumulator 300 is more suitable for the internal structure of the liquid accumulator 300 itself, does not affect the gas-liquid separation capability of the liquid accumulator 300, can effectively prevent the refrigerant liquid from entering the compressor, prevent the occurrence of liquid hammering, and effectively improve the service life of the compressor.

[0050] Please refer to Figure 1 The refrigeration equipment 10 includes a first cover plate 400, the first cover plate 400 is arranged between the storage chamber 101 and the heat exchange chamber 102, the first cover plate 400 plays a role of isolation, so that the evaporator 200 is hidden under the first cover plate 400, preventing the user from directly touching the evaporator 200.

[0051] The refrigeration equipment 10 further includes a heater (not shown), the heater is installed on the evaporator 200, the heater is used for heating the evaporator 200, so as to melt the frost condensed on the evaporator 200 when needed, the heater is configured to generate heat in the powered state, for example, the heater can be an electric heating pipe. The refrigeration equipment 10 further includes a heat insulation piece 700, the heat insulation piece 700 is arranged between the first cover plate 400 and the evaporator 200, the heat insulation piece 700 is made of a material with good heat insulation property, the heat insulation piece 700 can block the heat generated by the heating piece from being transmitted to the first cover plate 400, preventing the heat from being transmitted to the storage chamber 101 through the first cover plate 400, and avoiding affecting the temperature in the storage chamber 101.

[0052] Please continue to refer to Figure 1 The refrigeration equipment 10 further includes a second cover plate 500, the second cover plate 500 is connected to one side of the first cover plate 400 facing the storage chamber 101, the second cover plate 500 is spaced from the rear wall 110 of the barrel body 100 and defines an air passing cavity 510, the air passing cavity 510 is in communication with the heat exchange chamber 102. In an embodiment, the liquid accumulator 300 is arranged on the side of the evaporator 200 close to the rear wall 110 of the barrel body 100, and at least part of the liquid accumulator 300 is located in the air passing cavity 510.

[0053] As the above embodiment limits the height position of the first refrigerant input end 320 of the liquid accumulator 300, the liquid accumulator 300 is relatively high, and the liquid accumulator 300 is higher than the evaporator 200. In the above embodiment, at least part of the liquid accumulator 300 is arranged in the air passing cavity 510, and at least part of the liquid accumulator 300 utilizes the space of the air passing cavity 510, so that the first cover plate 400 can be arranged close to the evaporator 200, and the height of the heat exchange chamber 102 can be designed according to the height required by the evaporator 200, without increasing the height of the heat exchange chamber 102 due to the arrangement of the liquid accumulator 300, thereby avoiding reducing the size of the storage space in the storage chamber 101.

[0054] It is easy to understand that the above second cover plate 500 can be used to form a refrigeration air duct of the refrigeration device 10. For example, in an embodiment, the refrigeration device 10 comprises a refrigeration air duct, the refrigeration air duct is arranged on the rear wall 110 of the tank body 100, the refrigeration air duct comprises the above second cover plate 500, that is, the second cover plate 500 is used as an air duct cover plate of the refrigeration air duct, the refrigeration air duct and the rear wall 110 of the tank body 100 define the above air passing cavity 510 through the second cover plate 500, the refrigeration air duct can be provided with an air outlet, and the air passing cavity 510 can be communicated with the storage chamber 101 through the air outlet, so that the air passing cavity 510 can communicate the heat exchange chamber 102 and the storage chamber 101. Then, the cold air in the heat exchange chamber 102 after heat exchange by the evaporator 200 can be sent into the storage chamber 101 through the air passing cavity 510 and the air outlet, so as to realize refrigeration of the storage chamber 101.

[0055] Of course, in other embodiments of the present application, the second cover plate 500 can also be used as an independent assembly, and at this time, the refrigeration device 10 can be provided with an additional refrigeration air duct, the refrigeration air duct can be connected to the end of the second cover plate 500 away from the first cover plate 400, and the refrigeration air duct can be provided with an air supply cavity to communicate with the air passing cavity 510.

[0056] In an embodiment, please refer to Figure 1 and refer to Figure 3 , Figure 3 for Figure 1 the structure shown in the sectional view along the section C-C, the width of the tank body 310 along the first direction is smaller than the width of the tank body 310 along the second direction, the first direction is parallel to the depth direction of the tank body 100, and the second direction is parallel to the width direction of the tank body 100. The width of the tank body 310 along the first direction is defined as D1, and the width of the tank body 310 along the second direction is defined as D2, then D1 < D2.

[0057] As at least part of the tank body 310 is located in the air passing cavity 510, the greater the width of the tank body 310 along the first direction, the greater the size of the air passing cavity 510 along the first direction in order to avoid interference between the liquid accumulator 300 and the second cover plate 500. In the embodiment, the width of the tank body 310 along the first direction is less than the width of the tank body 310 along the second direction, and the tank body 310 mainly utilizes the space of the air passing cavity 510 along the second direction. Compared with the traditional liquid accumulator adopting a cylindrical tank body, the tank body 310 of the embodiment is relatively flat in shape, reduces the occupation of the space in the air passing cavity 510 in the first direction, and can reduce the size of the air passing cavity 510 along the first direction and increase the length of the storage chamber 101 along the depth direction of the tank body 100.

[0058] In an embodiment, as shown in Figure 3 , the tank body 310 is configured as an elliptical cylinder.

[0059] Please refer to Figure 4 , Figure 4 , it is a partial structure diagram of the refrigeration equipment of the second embodiment of the utility model. The refrigeration equipment 10 comprises a box body 600 and a door body (not shown in the figure), the tank body 100 is arranged in the box body 600, and a compressor compartment 610 is arranged between the box body 600 and the tank body 100. The compressor compartment 610 is located at the side of the box body 600 close to the door body. It can be understood that the compressor, the condenser, the cooling fan and the water pan are arranged in the compressor compartment 610.

[0060] By arranging the compressor compartment 610 at the side of the box body 600 close to the door body, the traditional compressor compartment is equivalent to being front-mounted, and the compressor compartment 610 is away from the wall or the cabinet, thereby greatly reducing the influence of the wall or the cabinet on the heat dissipation of the condenser. In addition, the opening of the compressor compartment 610 can be directed to the open space in front of the box body 600, so that the compressor compartment 610 is directly communicated with the open space in front of the box body 600, and the air flow is good. In particular, when the refrigeration equipment 10 is an embedded refrigerator, the air inlet and outlet resistance during heat dissipation is reduced, the heat generated by the condenser and the compressor can be dissipated to the outside of the box body 600 in time, and the heat dissipation efficiency can be improved.

[0061] In an embodiment, please continue to refer to Figure 4 , the heat exchange chamber 102 is located at the side of the compressor compartment 610 away from the door body, i.e. the heat exchange chamber 102 is located at the rear side of the compressor compartment 610. Then, by front-mounting the compressor compartment 610, the heat exchange chamber 102 can be arranged in the space left by the front-mounting of the compressor compartment 610, so that the heat exchange chamber 102 and the compressor compartment 610 are arranged in the front-rear direction of the box body 600, and the bottom of the storage chamber 101 is as flat as possible, instead of being greatly protruded at the rear side due to the arrangement of the compressor compartment as in the related art, which is beneficial to the storage of the refrigeration equipment 10.

[0062] In an embodiment, the evaporator 200 is arranged obliquely along the depth direction of the shell body 100, and the end of the evaporator 200 away from the rear wall 110 of the shell body 100 is lower than the end of the evaporator 200 close to the rear wall 110 of the shell body 100, that is, the rear end position of the evaporator 200 is higher than the front end position of the evaporator 200.

[0063] By arranging the evaporator 200 obliquely, the defrosting water of the evaporator 200 can be discharged in time, and the defrosting water is prevented from staying at the evaporator 200 to be condensed into ice again. Since the compressor compartment 610 is arranged at the front side of the box body 600, by arranging the rear end position of the evaporator 200 to be higher than the front end position of the evaporator 200, the defrosting water can flow to the front side under the action of gravity, so as to flow into the water pan of the compressor compartment 610 through the drain pipe.

[0064] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
