[0039] The present application provides a kind of refrigeration equipment, refrigeration equipment can be refrigerator, freezer.

[0040] Please refer to Figure 1 、 Figure 2 And Figure 3 , Figure 1 the structure diagram of the refrigeration equipment of the embodiment of the present application, Figure 2 the assembly structure diagram of the gallbladder and evaporator and fan of the embodiment of the present application, Figure 3 the structure diagram of the gallbladder of the embodiment of the present application, refrigeration equipment 10 includes gallbladder 200 and the cover plate assembly and fan 500 arranged in gallbladder 200, cover plate assembly includes cover plate 300.

[0041] Among them, cover plate 300 and gallbladder 200 define heat exchange chamber 202 and storage room 201, heat exchange chamber 202 is located at the bottom of storage room 201. Heat exchanger can be arranged in heat exchange chamber 202, for example, the evaporator of refrigeration equipment 10 can be installed in heat exchange chamber 202, storage room 201 is used to store goods, and storage drawer can be arranged in storage room 201.

[0042] Heat exchange chamber 202 is located at the bottom of storage room 201, i.e. heat exchange chamber 202 and storage room 201 are arranged along the height direction of gallbladder 200, such asFigure 2 The middle upper and lower direction is arranged, which is different from the traditional refrigerator that arranges the storage chamber and the heat exchange chamber along the depth direction of the cabinet body. For example, the cover plate 300 can extend along the depth direction of the cabinet body 200 (as shown by the middle front and rear direction), which divides the cabinet body 200 into two spaces in the upper and lower directions, and the upper side space of the cover plate 300 forms the storage chamber 201, and the lower side space of the cover plate 300 forms the heat exchange chamber 202. Figure 2

[0043] The fan 500 is installed on the cover plate assembly and is arranged in the heat exchange chamber 202. The fan 500 can adopt an axial flow fan or a centrifugal fan, and the embodiments of the present application do not make any limitation thereon.

[0044] In the related art, the traditional refrigerator generally arranges the fan in the air duct, and the air duct is generally installed on the rear wall of the cabinet body. Since the fan occupies the internal space of the air duct, the thickness of the air duct is relatively large, which reduces the length of the storage chamber along the depth direction of the cabinet body, and causes the length of the storage drawer to be relatively short. The embodiments of the present application arrange the fan 500 in the heat exchange chamber 202, and the heat exchange chamber 202 is located at the bottom of the storage chamber 201. The fan 500 utilizes the space at the bottom of the storage chamber 201. Compared with the traditional refrigerator that arranges the fan in the air duct, the fan 500 does not occupy the internal space of the air duct, which reduces the design thickness of the air duct and can increase the length of the storage chamber 201 along the depth direction of the cabinet body 200, thereby increasing the length of the storage drawer.

[0045] Moreover, the embodiments of the present application install the fan 500 on the cover plate assembly, and the fan 500 and the cover plate assembly can be connected as a whole. Therefore, during the assembly process of the refrigeration equipment 10, the fan 500 and the cover plate assembly can be integrally installed in the cabinet body 200. Compared with the traditional refrigerator that connects and fixes the fan with the cabinet body, the step of separately installing the fan 500 and the cabinet body 200 is omitted, and the production efficiency of the refrigeration equipment 10 can be improved.

[0046] Reference Figure 2 As shown in the figure, the refrigeration equipment 10 includes a refrigeration air duct 700, which is installed on the rear wall 210 of the cabinet body 200. The refrigeration air duct 700 is provided with an air inlet (not shown in the figure) and a first air outlet (not labeled). The air inlet is in communication with the heat exchange chamber 202, and the first air outlet is in communication with the storage chamber 201. Under the action of the wind power of the fan 500, the cold air in the heat exchange chamber 202 can enter the refrigeration air duct 700 through the air inlet, and then be sent into the storage chamber 201 through the first air outlet, so as to realize the refrigeration of the storage chamber 201.

[0047] Please continue to refer to Figure 2 ​The refrigeration equipment 10 further comprises an evaporator 600, which is arranged in the heat exchange chamber 202, i.e., the evaporator 600 is arranged at the bottom of the storage chamber 201. Compared with the conventional refrigerator, the evaporator 600 is arranged close to the rear wall 210 of the barrel body 200, and no installation space is reserved between the refrigeration air duct 700 and the rear wall 210 of the barrel body 200, so that more space can be left on the front side of the refrigeration air duct 700, and the length of the storage chamber 201 in the depth direction of the barrel body 200 can be further increased, and the length of the storage drawer can be further increased.

[0048] In an embodiment, the refrigeration equipment 10 further comprises a cabinet 100 and a door body 900, and the barrel body 200 is installed in the cabinet 100. The bottom of the cabinet 100 is provided with a first mechanical chamber 101, which is formed between the barrel body 200 and the cabinet 100, and is located on the side of the cabinet 100 close to the door body 900, i.e., the first mechanical chamber 101 is located on the front side of the cabinet 100. In an embodiment, the compressor, the condenser, the heat dissipation fan and the water pan are arranged in the first mechanical chamber 101, i.e., the first mechanical chamber 101 is used as a compressor compartment of the refrigeration equipment 10.

[0049] It can be understood that by arranging the first mechanical chamber 101 on the side of the cabinet 100 close to the door body 900, the conventional compressor compartment is moved to the front, and the first mechanical chamber 101 is away from the wall or the cabinet, which greatly reduces the influence of the wall or the cabinet on the heat dissipation of the condenser. The opening of the first mechanical chamber 101 can face the open space on the front side of the cabinet 100, so that the first mechanical chamber 101 is directly communicated with the open space on the front side of the cabinet 100, and the air flow is good. Especially for the 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 cabinet 100 in time, and the heat dissipation efficiency can be improved.

[0050] Please refer to Figure 2 The heat exchange chamber 202 is located on the side of the first mechanical chamber 101 away from the door body 900, i.e., the heat exchange chamber 202 is located on the rear side of the first mechanical chamber 101. Therefore, by moving the conventional compressor compartment to the front, the heat exchange chamber 202 can be arranged in the space left by the movement of the compressor compartment to the front, and the heat exchange chamber 202 and the first mechanical chamber 101 are arranged in the front-rear direction of the cabinet 100, so that the bottom of the storage chamber 201 is as flat as possible, instead of being greatly protruded on the rear side of the storage chamber 201 due to the arrangement of the compressor compartment in the related art, which is beneficial to the storage of the refrigeration equipment 10.

[0051] As the first mechanical chamber 101 is arranged at the front side of the heat exchange chamber 202, to facilitate the defrosting water of the evaporator 600 to flow forward to the water pan in the first mechanical chamber 101, in an embodiment, the cover plate 300 comprises a first cover plate 310 extending along the depth direction of the shell body 200, the first cover plate 310 separates the shell body 200 into the heat exchange chamber 202 and the storage chamber 201, the shell body 200 comprises a bottom wall 220 and a rear wall 210, the distance between the bottom wall 220 and the first cover plate 310 increases from the end of the bottom wall 220 close to the rear wall 210 to the end of the bottom wall 220 away from the rear wall 210. As shown in Figure 2 the bottom wall 220 of the shell body 200 is arranged to be inclined downward, so that the defrosting water can flow into the water pan in the first mechanical chamber 101 under the action of gravity.

[0052] In an embodiment, the fan 500 is located at the side of the evaporator 600 away from the rear wall 210 of the shell body 200, that is, the fan 500 is arranged at the front side of the evaporator 600.

[0053] As the distance between the bottom wall 220 and the first cover plate 310 increases from the end of the bottom wall 220 close to the rear wall 210 to the end of the bottom wall 220 away from the rear wall 210, the front side space of the heat exchange chamber 202 is greater than the rear side space of the heat exchange chamber 202, by arranging the fan 500 at the front side of the evaporator 600, that is, the evaporator 600 is located at the rear side space of the heat exchange chamber 202 and the fan 500 is located at the front side space of the heat exchange chamber 202, the front side of the heat exchange chamber 202 has relatively larger space, which is conducive to the arrangement of the fan 500. In particular for the axial flow fan 501, the axial flow fan can make full use of the front side space of the heat exchange chamber 202 to be arranged vertically, adapt to the air inlet and outlet mode of the axial flow fan, and fully exert the air outlet efficiency of the axial flow fan.

[0054] In an embodiment, the fan 500 is arranged spaced apart from the evaporator 600, and an air passing gap is formed between the fan 500 and the evaporator 600. As the fan 500 is arranged at the front side of the evaporator 600, the fan 500 blows air to the evaporator 600, if the fan 500 is arranged close to the evaporator 600, the fan 500 can only blow air to a small part of the evaporator 600 facing the fan 500. In this embodiment, the fan 500 is arranged spaced apart from the evaporator 600, the air blown out of the fan 500 flows into the air passing gap, the air is more easily diffused to the surroundings, so that the air can blow to more areas of the evaporator 600 for heat exchange, effectively increasing the heat exchange area of the air and the evaporator 600, improving the utilization rate of the evaporator 600, and improving the heat exchange efficiency. On the other hand, by arranging the fan 500 at a certain distance from the evaporator 600, the influence of the overcooling of the evaporator 600 on the start of the fan 500 can be avoided.

[0055] In an embodiment, the minimum distance between the fan 500 and the evaporator 600 is 50 mm.

[0056] In an embodiment, the fan 500 adopts an axial fan, and a rotation axis direction of the axial fan is parallel or inclined to a depth direction of the tank body 200. It should be noted that the parallel herein can be that the two are exactly parallel or that the two are approximately parallel, and absolute parallel is not required. Due to manufacturing precision and assembly precision, a small-angle deviation of the rotation axis of the axial fan relative to the depth direction of the tank body 200 can also be regarded as parallel.

[0057] Please combine Figure 2 and refer to Figure 4 and Figure 5 , Figure 4 the assembly schematic view of the axial fan and the cover plate of the embodiment of the utility model, Figure 5 the structure schematic view of the cover plate, the cover plate 300 includes a first cover plate 310, the first cover plate 310 extends along the front-back direction of the tank body 200, that is, the horizontal direction in the figure, the first cover plate 310 is connected with the tank body 200 and separates the tank body 200 into a heat exchange chamber 202 and a storage chamber 201, the storage chamber 201 is located on the upper side of the first cover plate 310, and the heat exchange chamber 202 is located on the lower side of the first cover plate 310. The cover plate assembly further includes a support plate 400, the support plate 400 is connected to one side of the first cover plate 310 facing the heat exchange chamber 202, the support plate 400 is arranged opposite to the evaporator 600, and the axial fan 501 is installed on the support plate 400.

[0058] As Figure 4 indicated, the support plate 400 is arranged opposite to the evaporator 600, that is, the support plate 400 is a plate arranged along the vertical direction (may be slightly inclined relative to the vertical plane), by installing the axial fan 501 on the support plate 400, the axial air inlet and outlet of the axial fan 501 can be exactly used, so that the return air entering the heat exchange chamber 202 can be blown horizontally to the evaporator 600, which is beneficial to heat exchange between the return air and the evaporator 600. Moreover, since the axial fan 501 is arranged vertically, and the support plate 400 is arranged along the vertical direction, the axial fan 501 and the support plate 400 have a large installation contact surface, so that the axial fan 501 can be firmly installed on the support plate 400, and the operation of the axial fan 501 is facilitated.

[0059] The support plate 400 is provided with a wind passing hole (not labeled), and the axial flow fan 501 can be installed on the side of the support plate 400 facing the evaporator 600, the air inlet of the axial flow fan 501 communicates with the wind passing hole, and when the axial flow fan 501 operates, negative pressure is generated to suck the air in the storage chamber 201 into the heat exchange chamber 202, and then into the axial flow fan 501 from the wind passing hole of the support plate 400, and then blown to the evaporator 600 through the air outlet of the axial flow fan 501. Of course, the axial flow fan 501 can also be installed on the side of the support plate 400 away from the evaporator 600, and at this time the air outlet of the axial flow fan 501 communicates with the wind passing hole. The drawings of the present embodiment only illustrate the former as an example and cannot be regarded as a limitation of the present application.

[0060] Please refer to Figure 2 and Figure 4 , the support plate 400 divides the heat exchange chamber 202 into a cooling cavity 2021 and a return air cavity 2022, the cooling cavity 2021 and the return air cavity 2022 are arranged along the depth direction of the gallbladder body 200, the evaporator 600 is arranged in the cooling cavity 2021, the first cover plate 310 is provided with a return air opening 311, and the return air opening 311 communicates the return air cavity 2022 and the storage chamber 201. Specifically, during the refrigeration process, the air in the storage chamber 201 after heat exchange is sucked into the return air cavity 2022 through the return air opening 311 under the action of negative pressure, and then enters the cooling cavity 2021 through the wind passing hole of the support plate 400 to exchange heat with the evaporator 600.

[0061] It can be understood that the return air opening 311 needs to be arranged in the area of the first cover plate 310 facing the return air cavity 2022, so that the storage chamber 201 only communicates with the return air cavity 2022 through the return air opening 311, and will not communicate with the cooling cavity 2021 through the return air opening 311, preventing the return air flow from the return air cavity 2022 into the cooling cavity 2021 from being reheated by the evaporator 600 and returning to the storage chamber 201.

[0062] The fan 500 will vibrate during operation, and the fan 500 is installed on the cover plate assembly. If the cover plate assembly is not stably installed, the fan 500 will shake the cover plate assembly when it vibrates, which in turn aggravates the vibration of the fan 500, generates vibration noise, and affects the normal operation of the fan 500. For this purpose, please refer to Figure 5 , the first cover plate 310 is provided with a connecting portion 312, and the first cover plate 310 is connected to the gallbladder body 200 through the connecting portion 312. The connecting portion 312 can be provided with a connecting hole, and the first cover plate 310 is fixed to the gallbladder body 200 by means of fasteners penetrating the connecting hole. Among them, the fastener can be a screw or a rivet.

[0063] Since the axial flow fan 501 is installed on the support plate 400, the vibration generated during the operation of the axial flow fan 501 mainly acts on the support plate 400. In order to prevent the axial flow fan 501 from driving the support plate 400 to shake, in an embodiment, the bottom wall 220 of the tank body 200 is provided with a limiting portion (not shown in the figure), and the end of the support plate 400 away from the first cover plate 310 is clamped with the limiting portion.

[0064] In an embodiment, the bottom wall 220 of the tank body 200 can form a limiting groove, and the end of the support plate 400 away from the first cover plate 310 is inserted into the limiting groove. The limiting groove limits the freedom of the end of the support plate 400 to move back and forth along the depth direction of the tank body 200. Then, the upper end of the support plate 400 is fixedly connected with the first cover plate 310, and the lower end of the support plate 400 is limitedly matched with the limiting groove, so that the upper and lower ends of the support plate 400 are both limited, thereby enhancing the installation stability of the support plate 400. At the same time, the vibration of the axial flow fan 501 acting on the support plate 400 can be transmitted to the tank body 200, which can greatly improve the situation that the support plate 400 shakes due to the vibration of the axial flow fan 501, avoid intensifying the vibration of the axial flow fan 501, and effectively reduce the vibration noise.

[0065] In an embodiment, the support plate 400 is integrally formed with the first cover plate 310. Then, the support plate 400 and the first cover plate 310 are an integral whole, which saves the connection step of the support plate 400 and the first cover plate 310, and further improves the production efficiency.

[0066] In an embodiment, please refer to Figure 2 and Figure 5 The cover plate 300 can further include a second cover plate 320, which is connected to the end of the first cover plate 310 close to the refrigeration air duct 700. The second cover plate 320 is located in the storage compartment 201 and abuts against the refrigeration air duct 700. The refrigeration air duct 700 can support the second cover plate 320, so that the cover plate 300 is stably installed in the tank body 200.

[0067] In another embodiment, please refer to Figure 6 , Figure 6 is a schematic assembly view of the centrifugal fan and the cover plate of the embodiment of the utility model. The fan 500 adopts a centrifugal fan 502, and the rotation axis direction of the centrifugal fan 502 is parallel to the height direction of the tank body 200, that is, the rotation axis of the centrifugal fan 502 is arranged along the vertical direction in the figure. As above, the parallel here can mean that the two are exactly parallel, or that the two are approximately parallel, and does not require absolute parallelism. Due to the influence of manufacturing precision and assembly precision, a small angle of inclination of the rotation axis of the centrifugal fan 502 relative to the vertical direction can also be regarded as parallel.

[0068] In the embodiment, the cover plate 300 comprises a first cover plate 310, the first cover plate 310 extends along the front-rear direction of the shell body 200, that is Figure 6 The first cover plate 310 is connected with the shell body 200 and divides the shell body 200 into the heat exchange chamber 202 and the storage chamber 201, the storage chamber 201 is located at the upper side of the first cover plate 310, and the heat exchange chamber 202 is located at the lower side of the first cover plate 310. The first cover plate 310 is provided with a return air port 311, and a centrifugal fan 502 is installed on the side of the first cover plate 310 facing the heat exchange chamber 202, the air inlet of the centrifugal fan 502 is communicated with the return air port 311, and the air outlet of the centrifugal fan 502 faces the evaporator 600.

[0069] Since the first cover plate 310 is a plate arranged along the horizontal direction, by installing the centrifugal fan 502 in a transverse arrangement on the first cover plate 310, the air inlet and air outlet mode of the axial air inlet and radial air outlet of the centrifugal fan 502 is utilized, the maximum air outlet efficiency of the centrifugal fan 502 can be achieved, the return air can be blown to the evaporator 600, and the return air efficiency is improved. Moreover, since the centrifugal fan 502 is arranged in a transverse arrangement and the first cover plate 310 is arranged along the horizontal direction, by installing the centrifugal fan 502 on the first cover plate 310, the centrifugal fan 502 has a large installation contact area with the support plate 400, the stable installation of the centrifugal fan 502 on the first cover plate 310 can be ensured, and the operation of the centrifugal fan 502 is facilitated.

[0070] The refrigeration equipment 10 further comprises a heater, the heater is used for heating the evaporator 600, so that the frost condensed on the evaporator 600 is melted. In an embodiment, the heater is configured as an electric heating pipe, the electric heating pipe generates heat in the electrified state.

[0071] In order to prevent the heat generated by the heater from affecting the temperature in the storage chamber 201, in an embodiment, referring to Figure 4 and Figure 6 The refrigeration equipment 10 further comprises a heat insulation piece 800, the heat insulation piece 800 is arranged between the first cover plate 310 and the evaporator 600.
