[0055] A freezer is a professional storage tool for storing various items that need to be frozen, which can keep food or other items in a frozen state, and is divided into household and commercial types. The refrigeration system of a freezer consists of parts such as a compressor, a condenser, a capillary tube, and an evaporator. Through the continuous circulation of the refrigerant, the heat inside the freezer is brought outside the freezer to achieve the purpose of cooling.

[0056] In order to reduce the problem of condensation inside the freezer, the air-cooling method can be adopted for refrigeration. The cold air is circulated through the fan to ensure that the food and beverages can maintain a roughly consistent temperature throughout the freezer. However, in the related art, the cold air mode of the air duct module of the freezer is prone to a large temperature difference inside the freezer, resulting in poor refrigeration effect. The horizontal freezer provided by the embodiment of the present application can cover different areas of the horizontal freezer as much as possible, thereby improving the freezing effect.

[0057] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0058] Please refer to Figure 1 and Figure 2 . The embodiment of the present application provides a horizontal freezer 10. The horizontal freezer 10 provided by the embodiment of the present application can cover different areas of the horizontal freezer 10 as much as possible, thereby improving the freezing effect.

[0059] Refer to Figure 3 . In the embodiment of the present application, the horizontal freezer 10 includes: a cabinet body 200, an air duct module 100, an evaporator 320 and a refrigeration component 330. The cabinet body 200 has a receiving cavity 211 for accommodating frozen items; both the air duct module 100 and the evaporator 320 are installed in the receiving cavity 211; the refrigeration component 330 is wound around the side wall of the receiving cavity 211.

[0060] The horizontal freezer 10 is mainly used for refrigerating items. The cabinet body 200 is the main structure of the entire horizontal freezer 10, which can provide an installation foundation for structures such as the air duct module 100, the compressor 310, the evaporator 320, and the condenser 340, and can also play a role in protecting the above-mentioned electronic components.

[0061] Among them, the cabinet body 200 includes a main body 220 and a door body 230 connected to the main body 220. The door body 230 covers the opening of the main body 220. The receiving cavity 211 is arranged in the main body 220, and the items to be refrigerated are arranged in the receiving cavity 211. The items are frozen by the cold air blown out by the air duct module 100. The main body 220 includes an inner liner 221 and an outer shell 223. The inner liner 221 and the outer shell 223 are filled with a foaming layer 370. There is an electrical cavity 215 for accommodating the compressor 310 between the inner liner 221 and the outer shell 223, and the electrical control component 350 is also arranged in the electrical cavity 215.

[0062] The main body 220 is generally a cuboid. For the convenience of description, the height direction Z, the width direction X and the thickness direction Y are respectively defined. Among them, in the use state of the horizontal freezer 10, the vertical direction is the height direction Z, and the projection of the main body 220 in the vertical direction is a rectangle. The direction where the long side is located is the width direction X, and the direction where the wide side is located is the thickness direction Y.

[0063] Since the thickness of the air duct module 100 is relatively small compared to its width, and the width of the air duct module 100 is basically equal to the thickness of the cabinet body 200, the air duct module 100 can be installed on one side of the cabinet body 200 in the width direction X, so that the air blown out from the air duct module 100 can cover the side surface formed by the length direction and the width direction X as much as possible. Furthermore, the air blown out from the air duct module 100 can cover the entire interior of the cabinet body 200, thereby improving the uniformity of freezing as much as possible.

[0064] Similarly, for the convenience of description, six directions, namely up, down, left, right, front, and back, are defined. Among them, in the height direction Z, the side close to the opening is up, and the side far from the opening is down. The two directions in the width direction X are respectively left and right. The installation position of the air duct module 100 is right, and the opposite side is left. In the thickness direction Y, the connection between the door body 230 and the main body 220 is the back, and the opposite side is the front.

[0065] Since the air duct module 100 is arranged on the right side inside the accommodation cavity 211, the condenser 340 can be wound around the front, back, and left sides of the cabinet body 200, thereby increasing the heat dissipation area of the condenser 340 and accelerating heat dissipation.

[0066] The refrigeration component 330 is wound around the outer side wall of the accommodation cavity 211, which means that the refrigeration component 330 is arranged between the inner liner 221 and the outer shell 223, that is, it can be arranged in the foaming layer 370 and wound around the inner liner 221, and is used to provide cold for the items in the accommodation cavity 211 to freeze the items in the accommodation cavity 211. The cold is provided to the accommodation cavity 211 in a liquid cooling manner. The air duct module 100 and the evaporator 320 cooperate to make the air duct module 100 blow cold air into the accommodation cavity 211, and refrigerate in an air cooling manner. By combining the two methods of air cooling and liquid cooling, the refrigeration effect can be improved while minimizing the condensation in the accommodation cavity 211.

[0067] In some embodiments, the accommodation cavity 211 has a bottom surface 213 and a stepped surface 214 higher than the bottom surface 213. The air duct module 100 is installed on the stepped surface 214, and the refrigeration component 330 is at least wound between the bottom surface 213 and the stepped surface 214.

[0068] When the user places items in the accommodation cavity 211, they usually start piling up from the bottom of the accommodation cavity 211. That is, the bottom of the accommodation cavity 211 is the easiest to be filled with items. If the air duct module 100 is directly arranged at the bottom of the accommodation cavity 211, the items are likely to block the air outlet of the air duct module 100, resulting in the inability of the gas in the accommodation cavity 211 to return, which is likely to cause the gas in the accommodation cavity 211 to not circulate, and further cause the lack of cold in the accommodation cavity 211, affecting the refrigeration effect.

[0069] In the embodiment of the present application, when the air duct module 100 is arranged on the step surface 214, it means that the air outlet of the air duct module 100 is at least above the step surface 214. The height of the step surface 214 is higher than the bottom surface 213 of the accommodation cavity 211, so that there is a certain height from the bottom surface 213 of the accommodation cavity 211, and there is a certain height between the air outlet of the air duct module 100 and the bottom surface 213. During the process of stacking items by the user, the air outlet with a certain height is not easily blocked, so that the gas in the accommodation cavity 211 can circulate, improving the refrigeration effect of the entire horizontal freezer 10.

[0070] The refrigerating member 330 is wound around the inner container 221 and at least wound in the area between the step surface 214 and the bottom surface 213. Since the air duct module 100 is arranged on the step surface 214, there may be a situation where the cold air cannot reach the area between the step surface 214 and the bottom surface 213. By arranging the refrigerating member 330 in the area between the step surface 214 and the bottom surface 213, this area can be cooled by the refrigerating member 330, thus ensuring the refrigeration effect of the entire horizontal freezer 10.

[0071] The refrigerating member 330 is at least wound in the area between the step surface 214 and the bottom surface 213 means that the refrigerating member 330 can be only wound between the step surface 214 and the bottom surface 213, or can be wound between the step surface 214 and the bottom surface 213 and also arranged above the step surface 214 at the same time.

[0072] Among them, the refrigerating member 330 can be a refrigerating coil or a patch evaporator, etc. The evaporator 320 can be a fin evaporator or a patch evaporator.

[0073] Please refer to Figure 3 and Figure 4 , in some embodiments, the cabinet 200 further includes an electrical cavity 215 for accommodating the compressor 310, and the step surface 214 is located above the electrical cavity 215.

[0074] Since the overall appearance of the entire cabinet 200 is approximately a cuboid, after the electrical cavity 215 is arranged between the inner container 221 and the outer shell 223, the inner container 221 is not a regular cuboid, that is, a step surface 214 will be formed above the electrical cavity 215. By arranging the return air outlet 114 at this position, the existing structure of the horizontal freezer 10 can be utilized, without separately arranging a step surface 214 higher than the bottom surface 213 in the accommodation cavity 211. This can not only improve the problem of blockage of the air outlet of the air duct module 100, but also reduce the number of components in the horizontal freezer 10 and reduce the occupation of the volume of the accommodation cavity 211.

[0075] Please refer to Figure 5, in some embodiments, the horizontal freezer 10 further includes an electric control component 350. The electric control component 350 is installed in the electrical cavity 215. There is an installation in the cabinet body 200, and the electric control component 350 is snap-connected to the installation part 361.

[0076] The installation part 361 can be embedded in the foaming layer 370. When assembling the electric control component 350, the electric control component 350 can be directly snap-connected to the installation part 361, and then the electric control component 350 is locked by screws, which can facilitate the assembly of the entire electric control component 350.

[0077] Please refer to Figure 6 , in some embodiments, a water collecting groove 216 is provided on the stepped surface 214. The horizontal freezer 10 further includes a water collecting box 362 and a connecting water pipe 363. The water collecting groove 216 is communicated with the water collecting box 362 through the connecting water pipe 363.

[0078] The water collecting groove 216 can be set as a V-shaped groove, and the connecting water pipe 363 can be arranged at the lowest point of the water collecting groove 216, so that all the condensed water in the water collecting groove 216 can enter the water collecting box 362 through the connecting water pipe 363.

[0079] In some embodiments, the horizontal freezer 10 further includes a positioning post 364. The positioning post 364 is connected to the connecting water pipe 363, and the positioning post 364 abuts against the lower part of the water collecting groove 216.

[0080] Among them, the water collecting box 362 can be arranged in the electrical cavity 215. Part of the connecting water pipe 363 is arranged in the foaming layer 370, part is arranged in the accommodating cavity 211, and part is arranged in the electrical cavity 215. Arranging the positioning post 364 on the connecting water pipe 363 can facilitate the assembly of the inner liner 221. When assembling, if the water collecting groove 216 touches the positioning post 364, it means that the inner liner 221 has been assembled in place in the height direction Z, which can facilitate the assembly of the entire cabinet body 200.

[0081] In some embodiments, the refrigeration component 330 is connected in series or in parallel with the evaporator 320. Parallel connection means that the compressor 310, the condenser 340, and the refrigeration component 330 form a refrigeration circuit, and the compressor 310, the condenser 340, and the evaporator 320 form another refrigeration circuit. Series connection means that the compressor 310, the condenser 340, the evaporator 320, and the refrigeration component 330 form the same refrigeration circuit.

[0082] Please refer to Figure 7 and Figure 8 , in some embodiments, the air duct module 100 includes a housing 120 and a drainage member 130. The housing 120 has an accommodating cavity 211, and the drainage member 130 is arranged in the accommodating cavity 211.

[0083] The housing 120 is the main body 220 of the entire air duct module 100 and is the basic component of the air duct module 100. It can provide an installation basis for other structures of the air duct module 100. Structures such as the flow guiding member 130 can be installed on the housing 120, enabling the air duct module 100 to form an integral whole, which facilitates the installation and transportation of the air duct module 100. At the same time, the housing 120 can also protect structures such as the flow guiding member 130 and reduce damage to the flow guiding member 130 and the like from external structures.

[0084] The flow guiding member 130 is mainly used for flow disturbance, enabling air to circulate in the refrigeration device, that is, the air in the refrigeration device can continuously flow to the evaporator 320, and after being cooled by the evaporator 320, it is blown towards the frozen items again.

[0085] Among them, the flow guiding member 130 can be a fan. Specifically, it can be a centrifugal fan, an axial flow fan, or a cross-flow fan.

[0086] The air outlet area of the first air outlet 112 being arc-shaped means that the air outlet area in the height direction Z of the horizontal freezer 10 is arc-shaped. The air outlet area in the height direction Z being arc-shaped enables the cold air blown out from the first air outlet 112 to have multiple different directions in the height direction Z. Furthermore, the cold air blown out from the first air outlet 112 can blow to different heights inside the horizontal freezer 10, enabling the cold air to flow at different heights inside the horizontal freezer 10 and covering as many different areas of the horizontal freezer 10 as possible, thereby improving the freezing effect.

[0087] In addition, since the air duct module 100 is applied to the horizontal freezer 10, the air outlet area of the first air outlet 112 is arc-shaped in the height direction Z of the horizontal freezer 10, that is, the air outlet area of the first air outlet 112 is arc-shaped in the vertical plane.

[0088] Among them, the air outlet area of the first air outlet 112 being arc-shaped can be that the shape of the first air outlet 112 is arc-shaped, or a wind sweeping member can be provided at the first air outlet 112 to form an arc-shaped air outlet area through the wind sweeping of the wind sweeping member.

[0089] In some embodiments, the air duct module 100 is installed on one side in the width direction X of the horizontal freezer 10. When the air duct module 100 is disposed inside the horizontal freezer 10, the first air outlet 112 is located above the return air outlet 114, and the air outlet area of the first air outlet 112 is arc-shaped, enabling the cold air blown out from the first air outlet 112 to have an upward flow trend. After the upward cold air is guided by the door body 230 of the horizontal door body 230, it can flow to the other side in the width direction X of the accommodation cavity 211, enabling the side of the accommodation cavity 211 far from the air duct module 100 to be blown by the cold air, thereby improving the uniformity of the cold air inside the accommodation cavity 211 as much as possible and further improving the refrigeration effect.

[0090] Since the air outlet direction of the first air outlet 112 is arc-shaped, while having an upward air outlet direction, it also has a leftward air outlet direction, that is, the first air outlet 112 also has a substantially horizontal air outlet direction, so that the cold air blown out from the first air outlet 112 can directly blow into the area around the air duct module 100, and further enables the first air outlet 112 to discharge air at different levels and freeze items at different positions.

[0091] The first air outlet 112 is located above the second air outlet 113, and the second air outlet 113 is located above the air return port 114.

[0092] Among them, the first air outlet 112, the second air outlet 113 and the air return port 114 are arranged in order from high to low. The first air outlet 112 is close to the top of the accommodation cavity 211, the air return port 114 is close to the bottom of the accommodation cavity 211, and the second air outlet 113 is roughly arranged in the middle area of the accommodation cavity 211, so that the cold air can form multiple different circulation areas and improve the refrigeration effect.

[0093] Specifically, when the user places items, they basically stack them from bottom to top. There are more items at the bottom and more cold air is needed. By arranging the second air outlet 113 between the first air outlet 112 and the air return port 114, the cold air can be discharged from the middle area of the cabinet body 200 approximately, and can blow into the bottom area of the accommodation cavity 211 as soon as possible. Through the cooperation of the first air outlet 112 and the second air outlet 113, the cold air can be blown more evenly into different areas of the accommodation cavity 211, and further the refrigeration effect is better.

[0094] The air duct module 100 is arranged on one side of the accommodation cavity 211 in the width direction X, and the first air outlet 112 is roughly arranged at the top of the accommodation cavity 211, and the second air outlet 113 is roughly arranged in the middle of the accommodation cavity 211. Since there is less possibility of placing items at the top of the accommodation cavity 211, the cold air blown out from the first air outlet 112 can be blown as much as possible to the other side of the accommodation cavity 211 in the width direction X, so that the area far from the air duct module 100 can be blown by the cold air. The second air outlet 113 is roughly arranged in the middle area of the accommodation cavity 211, so that the cold air blown out from the second air outlet 113 can directly blow onto the items near the air duct module 100, and further all the items in the accommodation cavity 211 can be blown by the cold air as much as possible, thereby improving the refrigeration effect of the entire horizontal freezer 10.

[0095] That is to say, in the embodiment of the present application, the first air outlet 112 is located above the second air outlet 113, and the air outlet area of the first air outlet is arc-shaped, so that the cold air blown out from the air duct module 100 can be blown to different heights in the accommodation cavity 211, so that the items in different areas can be directly blown by the cold air as much as possible, thereby improving the freezing effect.

[0096] Please refer to Figure 9 and Figure 10 , in some embodiments, at least a part of the first air outlet 112 is arc-shaped. The first air outlet 112 is located at the top of the housing 120. At least a part of the first air outlet 112 being arc-shaped can mean that the entire first air outlet 112 is arc-shaped, or a part of the first air outlet 112 is arc-shaped and the other part is linear. Specifically, it can be not limited.

[0097] The first air outlet 112 is located at the top of the housing 120 and is arc-shaped. The arc-shaped first air outlet 112 has multiple different air outlet directions. Since the first air outlet 112 is also located at the top of the housing 120, the cold air blown out from the first air outlet 112 can be blown upward and to the left. The upward cold air can flow to the left side of the cabinet 200 after being guided by the door body 230, and the cold air blown to the left can directly blow to the area near the air duct module 100. Furthermore, the cold air can flow as much as possible inside the entire cabinet 200, improving the refrigeration effect.

[0098] In some embodiments, the radian of the first air outlet 112 is 80 degrees to 100 degrees. The radian of the first air outlet 112 refers to the radian in the vertical plane. Specifically, the radian of the first air outlet 112 can be 80 degrees, 82 degrees, 85 degrees, 90 degrees, 95 degrees, etc.

[0099] The radian of the first air outlet 112 is 80 degrees to 100 degrees, so that the first air outlet 112 can cover the upper part and the left side of the air duct module 100 as much as possible. The first air outlet 112 can have a vertically upward air outlet direction at the top of the housing 120 as much as possible, a horizontally upper-left air outlet direction at the side of the housing 120, and also have multiple inclined upward-left air outlet directions between the vertically upward and the horizontally leftward. Furthermore, the cold air can flow to different areas inside the cabinet 200, and the cold air can circulate inside the cabinet 200, improving the refrigeration effect.

[0100] In some embodiments, the housing 120 has a first surface 126a and a second surface 126b that are arranged at an angle to each other. The first air outlet 112 is located on the first surface 126a and the second surface 126b respectively.

[0101] Among them, the first surface 126a is located at the top of the housing 120, the second surface 126b is located at the side of the housing 120, and the first air outlet 112 extends from the first surface 126a to the second surface 126b, so that part of the first air outlet 112 is located at the top of the housing 120 and part is located at the side of the housing 120. The middle transition region is connected by an arc transition, so that the entire first air outlet 112 is arc-shaped.

[0102] In some embodiments, there are multiple first air outlets 112. The multiple first air outlets 112 are located at the same height of the air duct module 100, and the multiple first air outlets 112 are all arc-shaped. That is, the cross-sections of the multiple first air outlets 112 in the vertical plane are all arc-shaped. The radian of the multiple first air outlets 112 can be the same or different, and can be set according to the actual situation.

[0103] The multiple first air outlets 112 are sequentially spaced apart in the thickness direction Y, so that the first air outlets 112 are arranged as much as possible in the thickness direction Y of the cabinet 200. Then, the air blown out from the multiple first air outlets 112 can cover as much as possible the plane formed by the width direction X and the thickness direction Y, improving the coverage area of the cold air, and thus improving the refrigeration effect.

[0104] In some embodiments, the second air outlet 113 is located on the second surface 126b. So that the first air outlet 112 and the second air outlet 113 can be located on the same side of the housing, and the first air outlet 112 and the second air outlet 113 can blow air in the width direction X of the cabinet 200, so that the cold air can flow as much as possible in the width direction X of the cabinet 200, can blow to a farther place, so that items in different regions can be blown by the cold air, and the situation of uneven temperature inside the cabinet 200 can be reduced as much as possible, improving the refrigeration effect.

[0105] In some embodiments, the first air outlet 112 is provided with an air outlet grille 112a. Since the first air outlet 112 is arc-shaped and has an upwardly disposed portion, in order to ensure the cold air volume of the first air outlet 112, the opening area of the first air outlet 112 will not be set particularly small. Also, since the first air outlet 112 is provided at the top of the cabinet 200, it is easy for some small-sized items to enter the interior of the housing 120 from the first air outlet 112 during the process of users taking and placing things. Setting the air outlet grille 112a on the first air outlet 112 can reduce the opening area of a single hole of the first air outlet 112, and thus can reduce the risk of small-sized items entering the housing 120 from the first air outlet 112.

[0106] In some embodiments, the air outlet grille 112a is injection-molded and connected to the housing 120. The air outlet grille 112a can be integrally formed with the housing 120 directly by injection molding, so that the air outlet grille 112a and the housing 120 form a whole, which can reduce the risk of the air outlet grille 112a falling off the housing 120, reduce the risk of the air outlet grille 112a falling into the housing 120, reduce the failure rate of the air duct module 100, and improve the service life of the air duct module 100.

[0107] In some embodiments, the air outlet grille 112a has a plurality of mesh holes 112b, and the plurality of mesh holes 112b are arranged at intervals, and the maximum width of each mesh hole 112b is less than or equal to 1.5 mm.

[0108] Wherein, the width of the mesh hole 112b can be the distance between any two points on the mesh hole 112b, and the maximum width is the two points with the farthest distance in the mesh hole 112b. Since the length of the rice grain is approximately 1.5 mm and the maximum width of the mesh hole 112b is less than or equal to 1.5 mm, it is possible to avoid rice grains or objects of the same volume level as rice grains from entering the housing 120 as much as possible, reduce the failure rate of the air duct module 100, and improve the service life of the air duct module 100.

[0109] In some embodiments, the air outlet grille 112a is at least disposed in the upper region of the first air outlet 112.

[0110] The upper region of the first air outlet 112 means that the air outlet direction of this region has an upward component, that is, the air outlet direction in this region can be vertically upward, can also be inclined upward, or can be partially vertically upward and partially inclined upward. The upper region of the first air outlet 112 faces the door body 230. After the door body 230 is opened, impurities are most likely to enter the housing 120 through this upper region. By arranging the air outlet grille 112a in the upper region, the risk of impurities entering the housing 120 can be reduced as much as possible.

[0111] The air outlet grille 112a being at least disposed in the upper region of the first air outlet 112 can be only disposed in the upper region of the first air outlet 112, or can be disposed in the upper region of the first air outlet 112 and in other regions of the first air outlet 112 except the upper region.

[0112] In some embodiments, the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 includes a first housing section 121a, a second housing section 121b, and a third housing section 121c. The second housing section 121b connects the first housing section 121a and the third housing section 121c respectively. The rear housing 123 is connected to the first housing section 121a to form an installation cavity 124. The second housing section 121b and the third housing section 121c are used to form a fixed cavity 125 for installing the evaporator 320 with the cabinet 200. Among them, the first air outlet 112 is provided on the first housing section 121a, and the air return opening 114 is provided on the third housing section 121c.

[0113] Please refer to Figure 8 and Figure 11 , the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 and the rear housing 123 are connected. The front housing 121 further includes a first housing section 121a, a second housing section 121b, and a third housing section 121c. The first housing section 121a is located above the second housing section 121b, and the second housing section 121b is located above the third housing section 121c. The first housing section 121a and the rear housing 123 form an installation cavity 124 for accommodating the drainage member 130. An air inlet 115 is provided on the rear housing 123. The air return opening 114 is provided on the third housing section 121c and is communicated with the fixed cavity 125.

[0114] Among them, when the air in the accommodation cavity 211 enters the fixed cavity 125 through the air return opening 114, under the action of the drainage member 130, it will flow towards the air inlet 115, so that the air entering the fixed cavity 125 will flow through the evaporator 320 for refrigeration and then flow into the installation cavity 124, and then blow into the accommodation cavity 211 through the first air outlet 112. That is to say, the evaporator 320 is arranged between the air return opening 114 and the air inlet 115 and refrigerates during the process of air circulation, so that the air blown out from the first air outlet 112 is always cold air, improving the refrigeration effect.

[0115] It should be noted that the evaporator 320 is fixed in the fixed cavity 125 jointly formed by the second housing section 121b, the third housing section 121c and the cabinet 200, which is convenient for the assembly of the air duct module 100 and the evaporator 320. During assembly, first assemble the air duct module 100 into a whole, assemble the evaporator 320 at the set position in the accommodation cavity 211, and then assemble the whole air duct module 100 into the accommodation cavity 211, so that the second housing section 121b and the third housing section 121c cover the evaporator 320 to form a closed fixed cavity 125 with the main body 220, so that the air in the accommodation cavity 211 can enter the fixed cavity 125 through the air return opening 114, flow through the evaporator 320 for refrigeration and then flow to the first air outlet 112.

[0116] In some embodiments, the third housing segment 121c protrudes from the second housing segment 121b, and the air return opening 114 is disposed at one end of the third housing segment 121c away from the second housing segment 121b.

[0117] The third housing segment 121c protruding from the second housing segment 121b means that the third housing 120 protrudes from the second housing segment 121b in the width direction X. That is, in the width direction X, the third housing segment 121c is disposed to the left of the second housing segment 121b, and the third housing segment 121c is closer to the central region of the accommodation cavity 211. The air return opening 114 is disposed at one end of the third housing segment 121c away from the second housing segment 121b and the first air outlet 112 is disposed on the first housing segment 121a. It can be considered that in the width direction X, among the air return opening 114 and the first air outlet 112, the air return opening 114 is disposed closer to the central region of the accommodation cavity 211, so that the gas in the accommodation cavity 211 can more easily enter the fixed cavity 125 through the air return opening 114, enabling the gas to stay and grow in the fixed cavity 125, thereby increasing the heat exchange time with the evaporator 320, improving the refrigeration effect on the air, and further improving the freezing effect.

[0118] Please refer to Figure 12 , in some embodiments, the air duct module 100 further includes a flow guiding member 140 disposed in the installation cavity 124, which can distribute the air volume to the first air outlet 112 and the second air outlet 113.

[0119] Among them, the front housing 121 and the rear housing 123 are in terms of the positions relative to the cabinet 200 of the refrigeration device. Among the front housing 121 and the rear housing 123, the rear housing 123 is disposed closer to the cabinet 200, that is, the rear housing 123 is located behind the front housing 121, and the front housing 121 and the rear housing 123 are connected to form the installation cavity 124.

[0120] The air inlet 115 is disposed on the rear housing 123, and the first air outlet 112 and the second air outlet 113 are disposed on the front housing 121. After being cooled by the evaporator 320 and through the action of the flow guiding member 130, the air can be blown from the first air outlet 112 and the second air outlet 113 into the cabinet 200 of the refrigeration device, and the cold air is blown out from the first air outlet 112 and the second air outlet 113.

[0121] Since the refrigeration device generally has a certain height, in order to enable the cold air to blow to different heights inside the cabinet 200 as much as possible, the first air outlet 112 and the second air outlet 113 can be disposed at different heights. That is, the first air outlet 112 can be disposed above the second air outlet 113, or the second air outlet 113 can be disposed above the first air outlet 112.

[0122] That is, the first air outlet 112 and the second air outlet 113 are located at different positions on the housing 120. After the diversion member 130 is installed in the installation cavity 124, the position of the diversion member 130 is determined. Due to factors such as the turning of the diversion member 130, the rotation speed of the diversion member 130, the position between the first air outlet 112 and the diversion member 130, and the position between the second air outlet 113 and the diversion member 130, the air volume of the first air outlet 112 and the second air outlet 113 is unstable.

[0123] A flow guide member 140 is arranged in the installation cavity 124. The flow guide member 140 can respectively guide the cold air entering the installation cavity 124 to the first air outlet 112 and the second air outlet 113. The air volume in the installation cavity 124 can be distributed through the flow guide member 140, so that the air volume of the cold air flowing to the first air outlet 112 and the second air outlet 113 can be approximately stable, thereby making the air volume blown to the refrigeration device approximately stable, and further ensuring the cold quantity at different heights in the refrigeration device and improving the refrigeration effect of the refrigeration device.

[0124] Specifically, since users generally place frozen items at the bottom first when placing them, there will be more frozen items piled up at the bottom. Therefore, the cold quantity demand at the bottom is relatively large. More cold quantity can be guided to the lower part of the refrigeration device through the diversion of the flow guide member 140. In addition, since the cabinet 200 of the refrigeration device is generally in a cuboid shape (long strip shape), and the air duct module 100 is installed on one side wall of the cabinet 200, the other opposite side wall is the farthest from the air duct module 100. As a result, the frozen items near the opposite side wall can absorb less cold quantity. The air outlet at the upper part can also be enlarged, so that the cold air can flow to a farther position, and then freeze the frozen items farther from the air duct module 100.

[0125] In some embodiments, the flow guide member 140 is installed on the rear shell 123 and is hermetically connected to the front shell 121. Since the air flow direction is from the air inlet 115 to the first air outlet 112 and the second air outlet, the flow guide member 140 can be installed on the rear shell 123 and hermetically connected to the front shell 121, so that the rear shell 123, the front shell 121 and the flow guide member 140 can form a diversion channel to respectively guide the cold air to the first air outlet 112 and the second air outlet 113.

[0126] Specifically, the flow guide member 140 is integrally formed with the rear shell 123, which can not only reduce the processing cost of the flow guide member 140 and the rear shell 123, but also reduce the sealing process between the rear shell 123 and the flow guide member 140, and further reduce the manufacturing cost.

[0127] In some embodiments, the air inlet 115 is arranged in a staggered manner with the first air outlet 112 and the second air outlet 113. This means that in the direction from the front housing 121 towards the rear housing 123, the air inlet 115 is arranged in a staggered manner with the first air outlet 112, and the air inlet 115 is arranged in a staggered manner with the second air outlet 113. This indicates that there is no direct through connection between the air inlet 115 and the first air outlet 112, and there is no direct through connection between the air inlet 115 and the second air outlet 113. When the cold air flows towards the first air outlet 112 and the second air outlet 113, it may collide with the front housing 121 or the rear housing 123, resulting in loss of kinetic energy. By arranging a flow guiding member 140 in the installation cavity 124, the cold air in the installation cavity 124 can be guided, reducing the loss of kinetic energy of the cold air, enabling the cold air to blow further into the cabinet 200, and thus improving the uniformity of the cold quantity in the cabinet 200 as much as possible and enhancing the refrigeration effect of the frozen items.

[0128] Please refer to Figure 13 、 Figure 14 and Figure 15 , in some embodiments, the first air outlet 112 includes a first left air outlet 112c and a first right air outlet 112d, the second air outlet 113 includes a second left air outlet 113c and a second right air outlet 113d, the flow guiding member 140 includes a first flow guiding portion 142 and a second flow guiding portion 145. The first flow guiding portion 142 and the second flow guiding portion 145 are respectively arranged on both sides of the air inlet 115. The first flow guiding portion 142 is correspondingly arranged with the first left air outlet 112c and the second left air outlet 113c, and the second flow guiding portion 145 is correspondingly arranged with the first right air outlet 112d and the second right air outlet 113d.

[0129] Among them, there are two first air outlets 112, namely the first left air outlet 112c and the first right air outlet 112d, and the first left air outlet 112c and the first right air outlet 112d are at the same height of the front housing 121. There are two second air outlets 113, namely the second left air outlet 113c and the second right air outlet 113d, and the second left air outlet 113c and the second right air outlet 113d are at the same height of the front housing 121.

[0130] For the convenience of description, taking the direction from the front housing 121 towards the rear housing 123 as the view direction, the first left air outlet 112c and the second left air outlet 113c are respectively located on the left side of the air inlet 115, and the first right air outlet 112d and the second right air outlet 113d are respectively located on the right side of the air inlet 115. The first left air outlet 112c is located above the second left air outlet 113c, and the first right air outlet 112d is located above the second right air outlet 113d.

[0131] Similarly, the first air guiding portion 142 is located on the left side of the air inlet 115, and the second air guiding portion 145 is located on the right side of the air inlet 115. The first air guiding portion 142 is configured to guide air to the first left air outlet 112c and the second left air outlet 113c, and the second air guiding portion 145 is configured to guide air to the first right air outlet 112d and the second right air outlet 113d.

[0132] Specifically, the shape of the first air guiding portion 142 can be set according to the heights of the first left air outlet 112c and the second left air outlet 113c and their positions relative to the air guiding member 130. Similarly, the shape of the second air guiding portion 145 can be set according to the heights of the first right air outlet 112d and the second right air outlet 113d and their positions relative to the air guiding member 130.

[0133] In some embodiments, the minimum distance between the first air guiding portion 142 and the air guiding member 130 is the first distance, and the minimum distance between the second air guiding portion 145 and the air guiding member 130 is the second distance;

[0134] When the air guiding member 130 turns from the second air guiding portion 145 to the first air guiding portion 142, the first distance is greater than the second distance.

[0135] Wherein, the air guiding member 130 can be a centrifugal impeller, and the air inlet 115 is generally circular. The air guiding member 130 can be installed at the air inlet 115. The first left air outlet 112c, the first right air outlet 112d, the second left air outlet 113c and the second right air outlet 113d are generally distributed at the four symmetric corners of the air inlet 115. The distance between the first air guiding portion 142 and the air guiding member 130 can be generally regarded as the distance between the first air guiding portion 142 and the air inlet 115. Specifically, the distance between the first air guiding portion 142 and the air inlet 115 refers to the distance between any point on the first air guiding portion 142 and the edge of the air inlet 115 along the radial direction of the air inlet 115. The minimum distance between the first air guiding portion 142 and the air guiding member 130 can be regarded as the minimum distance between the first air guiding portion 142 and the edge of the air inlet 115.

[0136] Since the first air guiding portion 142 extends from the air inlet 115 to the first left air outlet 112c and the second left air outlet 113c respectively, the minimum distance between the first air guiding portion 142 and the air guiding member 130 can be regarded as the first flow path between the first air guiding portion 142 and the air inlet 115.

[0137] Similarly, the distance between the second air guiding portion 145 and the air guiding member 130 can be approximately regarded as the distance between the second air guiding portion 145 and the air inlet 115. Specifically, the distance between the second air guiding portion 145 and the air inlet 115 refers to the distance between any point on the second air guiding portion 145 and the edge of the air inlet 115 along the radial direction of the air inlet 115. The minimum distance between the second air guiding portion 145 and the air guiding member 130 can be regarded as the minimum distance between the second air guiding portion 145 and the edge of the air inlet 115.

[0138] Since the second air guiding portion 145 extends from the air inlet 115 to the first right air outlet 112d and the second right air outlet 113d respectively, the minimum distance between the second air guiding portion 145 and the air guiding member 130 can be regarded as the second flow channel between the second air guiding portion 145 and the air inlet 115.

[0139] The air guiding member 130 turning from the second air guiding portion 145 to the first air guiding portion 142 means that in the direction from the front housing 121 to the rear housing 123, the air guiding member 130 rotates counterclockwise. During the rotation of the air guiding member 130, the air entering the accommodation cavity 211 from the air inlet 115 first flows to the second guiding portion and then to the first air guiding portion 142. If the first distance is greater than the second distance, it means that the first flow channel is greater than the second flow channel. Generally, the flow velocity of the air passing through the second air guiding portion 145 first will be slightly greater than that of the first air guiding portion 142. The first flow channel being greater than the second flow channel enables the air speeds flowing through the first air guiding portion 142 and the second air guiding portion 145 to be approximately the same, that is, the air volumes blown out from the first left air outlet 112c, the second left air outlet 113c, the first right air outlet 112d, and the second right air outlet 113d are approximately the same, as much as possible making the air volumes of different air outlets approximately the same, and as much as possible ensuring that the cold air has the same amount of cold for each part of the refrigeration device, improving the refrigeration effect of the refrigeration device.

[0140] In some embodiments, the first air guiding portion 142 includes a first upper air guiding section 142a and a first lower air guiding section 142b. One end of the first upper air guiding section 142a and one end of the first lower air guiding section 142b are connected to form a first connection point 142c. The end of the first upper air guiding section 142a away from the first connection point 142c extends to the first left air outlet 112c, and the end of the first lower air guiding section 142b away from the first connection point 142c extends to the second left air outlet 113c.

[0141] The first connection point 142c is the point on the first diversion part 142 closest to the air inlet 115, that is, the first connection point 142c is the point on the entire first diversion part 142 closest to the diversion member 130. The first upper diversion section 142a extends from the air inlet 115 to below the first left air outlet 112c, and can divert the cold air to the first left air outlet 112c. The first lower diversion section 142b extends from the air inlet 115 to above the second left air outlet 113c, and can divert the cold air to the second left air outlet 113c. That is, the first upper diversion section 142a and the first lower diversion section 142b are arranged between the first left air outlet 112c and the second left air outlet 113c.

[0142] As for the shape of the first upper diversion section 142a, it can be linear, arc-shaped, or a combination of linear and arc-shaped, and no specific limitation is required. Similarly, as for the shape of the first lower diversion section 142b, it can be linear, arc-shaped, or a combination of linear and arc-shaped.

[0143] In some embodiments, along the height direction Z of the housing 120, the inclination angle of the first upper diversion section 142a is greater than the inclination angle of the first lower diversion section 142b.

[0144] Wherein, the height direction Z of the housing 120 refers to the height direction Z (vertical direction) after the entire air duct module 100 is installed in the refrigeration equipment. Along the height direction Z of the housing 120, the inclination angle of the first upper diversion section 142a can be regarded as the angle of the first upper diversion section 142a in the vertical direction. The larger the inclination angle of the first upper diversion section 142a, the flatter the first upper diversion section 142a is, and the slower the diversion is. The smaller the inclination angle of the first upper diversion section 142a, the steeper the first upper diversion section 142a is, and the faster the diversion is.

[0145] Similarly, the larger the inclination angle of the first lower diversion section 142b in the height direction Z of the housing 120, the flatter the first lower diversion section 142b is, and the slower the diversion is. The smaller the inclination angle of the first lower diversion section 142b, the steeper the first lower diversion section 142b is, and the faster the diversion is.

[0146] The fact that the inclination angle of the first upper diversion section 142a is greater than the inclination angle of the first lower diversion section 142b indicates that the first upper diversion section 142a is relatively flatter than the first lower diversion section 142b. Since the first upper diversion section 142a is located above the first lower diversion section 142b and the diversion member 130 turns from the first upper diversion section 142a to the first lower diversion section 142b, the flow rate above is relatively larger than that below. That is, the first lower diversion section 142b below is set steeper, which can balance the flow difference between the upper and lower parts, so that the air volumes of the first left air outlet 112c and the second left air outlet 113c are approximately the same.

[0147] In some embodiments, the included angle between the first upper diversion section 142a and the first lower diversion section 142b is 0° to 90°. Since the first upper diversion section 142a and the first lower diversion section 142b are connected at the first connection point 142c and extend upward and downward respectively (extend in different directions), the smaller the included angle between the first upper diversion section 142a and the first lower diversion section 142b, the closer the distance between the first upper diversion section 142a and the first lower diversion section 142b, resulting in a larger space above the first upper diversion section 142a or / and below the first lower diversion section 142b, enabling more cold air to be diverted to the first left air outlet 112c and the second left air outlet 113c, and increasing the air output of the first left air outlet 112c and the second left air outlet 113c.

[0148] Specifically, the included angle between the first upper diversion section 142a and the first lower diversion section 142b can be 25°, 30°, 35°, 45°, 60°, 65°, etc.

[0149] In some embodiments, the second diversion part 145 includes a second upper diversion section 145a and a second lower diversion section 145b. One end of the second upper diversion section 145a and one end of the second lower diversion section 145b are connected to form a second connection point 145c. The end of the second upper diversion section 145a far from the second connection point 145c extends to the first right air outlet 112d, and the end of the second lower diversion section 145b far from the second connection point 145c extends to the second right air outlet 113d.

[0150] The second connection point 145c is the point on the second diversion part 145 closest to the air inlet 115, that is, the second connection point 145c is the point on the entire second diversion part 145 closest to the diversion member 130. The second upper diversion section 145a extends from the air inlet 115 to the lower part of the first right air outlet 112d, diverting cold air to the first right air outlet 112d. The second lower diversion section 145b extends from the air inlet 115 to the upper part of the second right air outlet 113d, diverting cold air to the second right air outlet 113d. That is, the second upper diversion section 145a and the second lower diversion section 145b are arranged between the first right air outlet 112d and the second right air outlet 113d.

[0151] As for the shape of the second upper diversion section 145a, it can be linear, arc-shaped, or a combination of linear and arc-shaped, and no specific limitation is required. Similarly, as for the shape of the second lower diversion section 145b, it can be linear, arc-shaped, or a combination of linear and arc-shaped.

[0152] In some embodiments, along the height direction Z of the housing 120, the inclination angle of the second upper diversion section 145a is greater than the inclination angle of the second lower diversion section 145b.

[0153] Among them, the height direction Z of the housing 120 refers to the height direction Z (vertical direction) after the entire air duct module 100 is installed in the refrigeration equipment. Along the height direction Z of the housing 120, the inclination angle of the second upper diversion section 145a can be considered as the angle of the second upper diversion section 145a in the vertical direction. The larger the inclination angle of the second upper diversion section 145a, the flatter the second upper diversion section 145a is, and the slower the diversion is. The smaller the inclination angle of the second upper diversion section 145a, the steeper the second upper diversion section 145a is, and the faster the diversion is.

[0154] Similarly, the larger the inclination angle of the second lower diversion section 145b in the height direction Z of the housing 120, the flatter the second lower diversion section 145b is, and the slower the diversion is. The smaller the inclination angle of the second lower diversion section 145b, the steeper the second lower diversion section 145b is, and the faster the diversion is.

[0155] That the inclination angle of the second upper diversion section 145a is greater than the inclination angle of the second lower diversion section 145b indicates that the second upper diversion section 145a is relatively flatter than the second lower diversion section 145b. Since the second upper diversion section 145a is located above the second lower diversion section 145b, the turning of the diversion member 130 is from the first lower diversion section 142b to the second upper diversion section 145a. The flow rate above is larger than that below. That is, the second lower diversion section 145b below is set steeper, which can balance the flow difference between the upper and lower parts, so that the air volumes of the first right air outlet 112d and the second right air outlet 113d are approximately the same.

[0156] In some embodiments, the included angle between the second upper diversion section 145a and the second lower diversion section 145b is 0° to 90°. Since the second upper diversion section 145a and the second lower diversion section 145b are connected at the second connection point 145c and extend upward and downward respectively (extend in different directions), the smaller the included angle between the second upper diversion section 145a and the second lower diversion section 145b, the closer the distance between the second upper diversion section 145a and the second lower diversion section 145b is, making the space above the second upper diversion section 145a or / and below the second lower diversion section 145b larger, and more cold air can be diverted to the first right air outlet 112d and the second right air outlet 113d, increasing the air output of the first right air outlet 112d and the second right air outlet 113d.

[0157] Specifically, the included angle between the second upper diversion section 145a and the second lower diversion section 145b can be 25°, 35°, 40°, 45°, 55°, 60°, 65° and 70°, etc.

[0158] In some embodiments, when the air guiding member 130 turns from the second air guiding portion 145 to the first air guiding portion 142, the air guiding angle of the first air guiding portion 142 is smaller than that of the second air guiding portion 145.

[0159] The air guiding angle of the first air guiding portion 142 refers to the included angle between the first upper air guiding section 142a and the first lower air guiding section 142b. Since the first upper air guiding section 142a and the first lower air guiding section 142b are not of the same shape (part of the first upper air guiding section 142a is linear and part is arc-shaped, and the radian of different sections may be different; part of the first lower air guiding section 142b is linear and part is arc-shaped, and the radian of different sections may be different), the included angle between the first upper air guiding section 142a and the first lower air guiding section 142b refers to the included angle at the first connection point 142c.

[0160] The air guiding angle of the second air guiding portion 145 refers to the included angle between the second upper air guiding section 145a and the second lower air guiding section 145b. Since the second upper air guiding section 145a and the second lower air guiding section 145b are not of the same shape (part of the second upper air guiding section 145a is linear and part is arc-shaped, and the radian of different sections may be different; part of the second lower air guiding section 145b is linear and part is arc-shaped, and the radian of different sections may be different), the included angle between the second upper air guiding section 145a and the second lower air guiding section 145b refers to the included angle at the second connection point 145c.

[0161] The air guiding angle of the first air guiding portion 142 being smaller than that of the second air guiding portion 145 indicates that the distance between the first upper air guiding section 142a and the first lower air guiding section 142b is relatively close, and the space above and below the first upper air guiding section 142a and the first lower air guiding section 142b is relatively large. On the contrary, it indicates that the distance between the second upper air guiding section 145a and the second lower air guiding section 145b is relatively close, and the space above and below the second upper air guiding section 145a and the second lower air guiding section 145b is relatively small. Since the second air guiding portion 145 turns to the first air guiding portion 142, the corresponding position of the second air guiding portion 145 is the air inlet side, and the corresponding position of the first air guiding portion 142 is the air outlet side. The air volume on the air inlet side is greater than that on the air outlet side. And the space above and below the first upper air guiding section 142a and the first lower air guiding section 142b is relatively large, while the space above and below the second upper air guiding section 145a and the second lower air guiding section 145b is relatively small, which can balance the air volume flowing to the first left air outlet, the second left air outlet 113c, the first right air outlet and the second right air outlet, making the air volume of the four air outlets roughly balanced and stable.

[0162] In some embodiments, the air guiding member 140 further includes a third air guiding portion 146, and the third air guiding portion 146 is disposed below the air guiding member 130 and is used for guiding air to the second left air outlet 113c and the second right air outlet 113d.

[0163] The third air guide part 146 is located below the rear shell 123 and can guide the cold air to the second left air outlet 113c and the second right air outlet 113d, so that the air volumes of the second left air outlet 113c and the second right air outlet 113d are approximately the same, thereby being able to improve the uniformity of the air outlet as much as possible.

[0164] Please refer to Figure 16 and Figure 17 , in some embodiments, the air duct module 100 further includes a fixing part cover plate 160 and a fixing part 150, and the housing 120 has an installation groove 128; the fixing part 150 is arranged in the installation groove 128 and is used for fixedly connecting the housing 120 and the cabinet body 200 of the refrigeration device, and the cover plate 160 covers the installation groove 128.

[0165] The installation cavity 124 and the installation groove 128 can be two independent cavities, that is, the installation cavity 124 and the installation groove 128 are not connected. When the drainage part 130 is installed inside the installation cavity 124 and the air duct module 100 is fixed to the refrigeration device, the drainage part 130 will not be exposed, and the damage to the drainage part 130 during the assembly of the air duct module 100 can be avoided as much as possible.

[0166] Of course, in some other embodiments, the installation cavity 124 and the installation groove 128 can also be partially communicated, and no specific limitation is made thereto.

[0167] In the embodiments of the present application, in order to facilitate description, the height direction, width direction X and thickness direction Y of the housing 120 are defined. As shown in the figure, the installation groove 128 can be arranged at the top of the entire housing 120. When the air duct module 100 is installed on the refrigeration device, the installation groove 128 is arranged close to the door body 230 of the refrigeration device, that is, the installation groove 128 is closest to the door body 230 of the refrigeration device. During installation, after the door body 230 is opened, it is convenient for the fixing part 150 to pass through the housing 120 and the cabinet body 200 of the refrigeration device, so as to facilitate the assembly of the air duct module 100.

[0168] In the embodiments of the present application, the fixing part 150 is arranged in the installation groove 128 and can fixedly connect the housing 120 and the cabinet body 200, while the cover plate 160 covers the installation groove 128 and can block the fixing part 150 in the installation groove 128, so that the cover plate 160 and the housing 120 can form a whole, the fixing part 150 can be hidden in the installation groove 128, and the fixing part 150 can be prevented from being exposed, making the appearance of the entire air duct module 100 neat.

[0169] In addition, the cover plate 160 shields the fixing member 150 within the installation groove 128, preventing the fixing member 150 from being exposed, reducing corrosion of the fixing member 150 caused by the low temperature or condensate water inside the refrigeration device, and increasing the service life of the fixing member 150.

[0170] Please refer to Figure 18 , in some embodiments, the housing 120 is provided with a fixing hole 129a. The fixing hole 129a communicates with the installation groove 128. A part of the fixing member 150 is received in the installation groove 128, and a part of the fixing member 150 passes through the fixing hole 129a for fixedly connecting with the cabinet body 200.

[0171] During the installation process, the fixing member 150 can be first placed in the installation groove 128, and then the fixing member 150 is pushed towards the cabinet body 200, so that the fixing member 150 passes through the fixing hole 129a and is fixedly connected with the cabinet body 200.

[0172] Specifically, the fixing member 150 can be a structure such as a screw or a bolt. Threaded holes can be provided on the cabinet body 200, and threads can or cannot be provided on the hole wall of the fixing hole 129a. During the assembly process, the fixing member 150 is first passed through the fixing hole 129a, and then the fixing member 150 is rotated so that the fixing member 150 can be locked within the cabinet body 200.

[0173] It should be noted that the air duct module 100 is installed within the cabinet body 200 and placed on the bearing surface. The fixing member 150 only serves a fixing function and basically does not bear the gravity of the air duct module 100.

[0174] In some embodiments, the cover plate 160 is snap-connected to the housing 120. After the housing 120 is fixed to the cabinet body 200, the cover plate 160 is then covered on the installation groove 128, such that the cover plate 160 is snap-connected to the housing 120, thereby installing the cover plate 160 on the housing 120.

[0175] As for the snap-connection method between the cover plate 160 and the housing 120, one of the cover plate 160 and the housing 120 can be provided with a snap-connection portion 162, and the other can be provided with a snap-connection hole 129b, and the snap-connection portion 162 is snap-connected to the snap-connection hole 129b. That is, the snap-connection portion 162 can be provided on the cover plate 160 and the snap-connection hole 129b can be provided on the housing 120. It can also be that the snap-connection hole 129b is provided on the cover plate 160 and the snap-connection portion 162 is provided on the housing 120, and no specific limitation is required.

[0176] Taking the example that the clamping portion 162 is provided on the cover plate 160 and the clamping hole 129b is provided on the housing 120 for specific illustration. The clamping portion 162 is provided below the cover plate 160. After the cover plate 160 is clamped with the housing 120, the cover plate 160 can also block the clamping portion 162, which can prevent the connection position of the clamping portion 162 and the clamping hole 129b from being exposed, and can improve the appearance beauty of the entire air duct module 100.

[0177] Please refer to Figure 18 and Figure 19 Specifically, the clamping portion 162 may include a connecting section 162a and a clamping section 162b. One end of the connecting section 162a is connected to the cover plate 160, and the other section is connected to the clamping section 162b. The connecting section 162a passes through the clamping hole 129b, and the clamping section 162b abuts against the side of the clamping hole 129b away from the cover plate 160, so that the cover plate 160 can be clamped with the housing 120.

[0178] Wherein, a plurality of clamping portions 162 and clamping holes 129b may be provided. For example, if the cover plate 160 is rectangular, at least one clamping portion 162 may be provided on each side of the cover plate 160. Correspondingly, a plurality of clamping holes 129b are also provided, and one clamping portion 162 is clamped with one clamping hole 129b. The number of the clamping portions 162 and the clamping holes 129b can be set according to the actual situation, and the specific number may not be limited.

[0179] Please refer to Figure 18 and Figure 20 In some embodiments, the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 and the rear housing 123 are connected to form an installation cavity 124, and the installation groove 128 is provided on the rear housing 123.

[0180] Wherein, the housing 120 may be a two-section housing 120 or a three-section housing 120. The front housing 121 and the rear housing 123 are relative to the position of the cabinet 200 of the refrigeration device. Among the front housing 121 and the rear housing 123, the rear housing 123 is closer to the cabinet 200, that is, the rear housing 123 is located behind the front housing 121, and the front housing 121 and the rear housing 123 are connected to form the installation cavity 124.

[0181] Since the installation groove 128 is mainly used to accommodate the fixing member 150, and the rear housing 123 is fixedly connected to the cabinet 200, arranging the installation groove 128 on the rear housing 123 can facilitate the assembly between the rear housing 123 and the cabinet 200.

[0182] In some embodiments, the rear shell 123 includes a main body 123a and a fixing portion 123b protruding from the main body 123a, and the mounting groove 128 is provided in the fixing portion 123b. The fixing portion 123b protruding from the main body 123a means that the fixing portion 123b protrudes from the main body 123a in the direction of the front shell 121. Of course, in order to adapt to the fixing portion 123b, a groove 121d can be provided on the front shell 121, and the fixing portion 123b can be arranged in the groove 121d.

[0183] Since the thickness of the main body 123a is very thin and it is impossible to directly form a mounting groove 128 on the main body 123a that can accommodate the fixing member 150, the mounting groove 128 can be arranged on the fixing portion 123b, which can not only not increase the thickness of the rear shell 123, but also set a mounting groove 128 that can accommodate the fixing member 150, simplifying the process and the structure is also relatively simple.

[0184] Specifically, the main body 123a and the fixing portion 123b can be integrally formed, which can reduce the manufacturing process of the entire rear shell 123 and reduce the manufacturing cost of the housing 120.

[0185] In some embodiments, the cover plate 160 is snap-connected to both the front shell 121 and the rear shell 123. Since the thicknesses of the front shell 121 and the rear shell 123 are relatively thin, the cover plate 160 being snap-connected to both the front shell 121 and the rear shell 123 can improve the fixing stability of the cover plate 160 and reduce the risk of the cover plate 160 detaching.

[0186] Of course, in addition to this, it can also be that the cover plate 160 is only snap-connected to the front shell 121, or the cover plate 160 is only snap-connected to the rear shell 123. The snap-connection methods of the cover plate 160 with the front shell 121 and the rear shell 123 can be the same or different, and no specific limitation is required.

[0187] The foregoing introduced the connection method between the cover plate 160 and the housing 120. Next, the connection method between the front shell 121 and the rear shell 123 will be introduced. In some embodiments, the front shell 121 can be snap-connected to the rear shell 123. As for the specific snap-connection method, snap holes can be provided on the front shell 121 and snap portions can be provided on the rear shell 123, and the snap holes and the snap portions are snap-connected. It can also be that snap holes are provided on the rear shell 123 and snap portions are provided on the front shell 121, and the snap portions and the snap holes are snap-connected.

[0188] Similarly, multiple snap holes and snap portions can be provided, and they can be respectively arranged along the edges of the front shell 121 and the rear shell 123.

[0189] In some other embodiments, it can also be that the front shell 121 has a first connection hole, the rear shell 123 has a second connection hole, and the air duct module 100 further includes a connecting member 170 (see Figure 7 ), and the connecting member 170 passes through the first connection hole and the second connection hole.

[0190] The connecting member 170 can be a screw or a nut. Threads can be provided on the inner walls of the first connecting hole and the second connecting hole, and the front shell 121 and the rear shell 123 are locked by the connecting member 170.

[0191] It should be noted that the above describes two connection methods between the front shell 121 and the rear shell 123. The two connection methods can exist simultaneously or only one of them can be selected. That is, the front shell 121 and the rear shell 123 can be connected by both snap connection and the connecting member 170, or the front shell 121 and the rear shell 123 can be only snap-connected, or the front shell 121 and the rear shell 123 can be only connected by the connecting member 170. The specific method can be not limited.

[0192] Please refer to Figure Figure 1 and Figure 21 , in some embodiments, the accommodation cavity 211 has a bottom surface 213 and a step surface 214 higher than the bottom surface 213, and the air return port 114 is located on the step surface 214.

[0193] When the user places an item in the accommodation cavity 211, it usually starts to pile up from the bottom of the accommodation cavity 211, that is, the bottom of the accommodation cavity 211 is the easiest to be filled with items. If the air return port 114 is directly arranged at the bottom of the box body, the item is likely to block the air return port 114, resulting in the inability of the gas in the accommodation cavity 211 to return, which is likely to cause the gas in the accommodation cavity 211 to not circulate, and further cause insufficient cold quantity in the accommodation cavity 211, affecting the refrigeration effect.

[0194] In the embodiment of the present application, the air return port 114 is located on the step surface 214, and the height of the step surface 214 is higher than the bottom surface 213 of the accommodation cavity 211, so that the air return port 114 has a certain height from the bottom surface 213 of the accommodation cavity 211. When the user stacks items, the air return port 114 with a certain height is not easily blocked, and further the gas in the accommodation cavity 211 can circulate, improving the refrigeration effect of the entire horizontal freezer 10.

[0195] Among them, the air return port 114 is located on the step surface 214, which does not mean that the air return port 114 is provided on the step surface 214, but means that the position of the air return port 114 is on the step surface 214, that is, the air return port 114 can be arranged above the step surface 214 or one side edge can be abutted against the step surface 214.

[0196] The main body 220 is roughly a cuboid. For the convenience of description, the height direction Z, the width direction X and the thickness direction Y are defined respectively. When the horizontal refrigerator 10 is in use, the vertical direction is the height direction Z, and the projection of the main body 220 in the vertical direction is a rectangle. The direction where the long side is located is the width direction X, and the direction where the wide side is located is the thickness direction Y.

[0197] Since the thickness of the air duct module 100 is smaller than the width, and the width of the air duct module 100 is substantially equal to the thickness of the cabinet 200, the air duct module 100 can be installed on one side of the cabinet 200 in the width direction X, so that the wind blown out from the first air outlet 112 can cover the side formed by the length direction and the width direction X as much as possible. The wind blown out from the first air outlet 112 can cover the interior of the entire cabinet 200, thereby improving the uniformity of freezing as much as possible.

[0198] Similarly, for the convenience of description, six directions are defined, namely, top, bottom, left, right, front, and back. In the height direction Z, the direction close to the opening is top, and the direction close to the bottom surface 213 is bottom. The two directions in the width direction X are left and right, respectively. The installation position of the air duct module 100 is right, and the opposite side is left. In the thickness direction Y, the connection between the door body 230 and the main body 220 is back, and the opposite side is front.

[0199] In some embodiments, the return air outlet 114 is tilted along the height direction Z of the cabinet 200 .

[0200] For the convenience of description, the return air outlet 114 is defined as having a first side 114a and a second side 114b that are relatively arranged, the second side 114b is located above the first side 114a, and the first side 114a abuts against the step surface 214. Along the height direction Z of the cabinet 200, the inclined arrangement of the return air outlet 114 means that the first side 114a and the second side 114b are staggered in the width direction X or the thickness direction Y, that is, along the height direction Z, the projections of the first side 114a and the second side 114b on the bottom surface 213 are staggered.

[0201] Specifically, the inclination direction of the return air outlet 114 can be toward the bottom surface 213 of the accommodating cavity 211 (that is, the second side 114b is set on the left side of the first side 114a), or toward the opening of the accommodating cavity 211 (that is, the first side 114a is set on the left side of the second side 114b).

[0202] The return air outlet 114 is tilted so that it has a certain angle in the height direction Z. The return air outlet 114 can form a smaller cavity with the step surface 214, thereby providing space for the gas in the accommodating cavity 211 to flow toward the return air outlet 114, reducing the risk of the return air outlet 114 being blocked, allowing cold air to circulate in the accommodating cavity 211, thereby improving the refrigeration effect of the entire horizontal freezer 10.

[0203] In some embodiments, the air return opening 114 is arranged facing the bottom surface 213, which means that the air return opening 114 is arranged to incline downward, that is, the second side 114b is located above the first side 114a and to the left of the first side 114a at the same time. The air return opening 114 being arranged facing the bottom surface 213 makes the air return direction of the air return opening 114 have a downward inclination trend.

[0204] Since the air return opening 114 is arranged on the stepped surface 214 and has a certain height from the bottom surface 213 of the accommodating cavity 211, cold air may not be able to flow into the area between the stepped surface 214 and the bottom surface 213. Arranging the air return opening 114 facing the bottom surface 213 makes the air return direction downward, so that cold air can flow into the area between the stepped surface 214 and the bottom surface 213, and can freeze the items placed between the stepped surface 214 and the bottom surface 213, thereby improving the freezing effect.

[0205] In some embodiments, along the height direction Z of the cabinet body 200, the air return opening 114 and the projection of the stepped surface 214 on the bottom surface 213 at least partially overlap.

[0206] Since the air return opening 114 is inclined, the projection of the air return opening 114 on the bottom surface 213 is also generally rectangular. The air return opening 114 and the projection of the stepped surface 214 on the bottom surface 213 are arranged to at least partially overlap, that is, the second side 114b may be located within the projection of the stepped surface 214 on the bottom surface 213, or may be located outside the projection of the stepped surface 214 on the bottom surface 213.

[0207] The fact that the air return opening 114 and the projection of the stepped surface 214 on the bottom surface 213 at least partially overlap means that it is sufficient to ensure that the first side 114a is located on the stepped surface 214. The second side 114b can be located within the area of the stepped surface 214 or to the left of the stepped surface 214, and the position of the first side 114a may not be specifically limited.

[0208] In some embodiments, along the height direction Z of the cabinet body 200, the second air outlet 113 is located at 3 / 5 to 4 / 5 of the cabinet body 200.

[0209] Among them, the second air outlet 113 is arranged at 3 / 5 to 4 / 5 of the cabinet body 200, that is, in the height direction Z of the cabinet body 200 and in the upward direction from the bottom, the second air outlet 113 is generally located at 0.6 to 0.8 of the cabinet body 200, so that the second air outlet 113 is generally located in the middle area of the horizontal freezer 10 in the height direction Z, so that the horizontal freezer 10 can directly blow to the items in the accommodating cavity 211, and can freeze the items in the area close to the air duct module 100, improving the refrigeration effect.

[0210] In some embodiments, along the height direction Z of the cabinet body 200, the air return opening 114 is located at the 1 / 4 to 1 / 2 position of the cabinet body 200. It means that in the vertical direction and from bottom to top, the air return opening 114 is located within the 1 / 4 to 1 / 2 area of the cabinet body 200, that is, the air return opening 114 is generally located in the lower area of the entire cabinet body 200 but there is still a certain distance from the bottom surface 213 of the accommodation cavity 211, so that the air return opening 114 is in the bottom area near the accommodation cavity 211. Without increasing the risk of blockage of the air return opening 114, cold air can flow to the bottom of the accommodation cavity 211 as much as possible, so that the cold air can penetrate the internal space of the entire accommodation cavity 211 as much as possible, thereby improving the refrigeration effect.

[0211] Please refer to Figure 22 and Figure 23 In some embodiments, a strengthening part 240 is provided on the cabinet body 200, and the fixing part 150 is fixedly connected to the housing 120 and the strengthening part 240.

[0212] The cabinet body 200 includes an inner liner 221 and an outer shell 223, and a foaming layer is filled between the inner liner 221 and the outer shell 223. Generally, the thickness of the inner liner 221 is relatively thin. The strengthening part 240 is arranged between the inner liner 221 and the outer shell 223, which enables the fixing part 150 to pass through the strengthening part 240, improving the fixing effect of the fixing part 150.

[0213] Please refer to Figure 24 In some embodiments, the cabinet body 200 is provided with a first positioning part 250, and the housing 120 is provided with a second positioning part 129c, and the first positioning part 250 and the second positioning part 129c cooperate with each other.

[0214] The first positioning part 250 can be a positioning groove, and the second positioning part 129c can be a protrusion. During the process of assembling the air duct module 100 into the accommodation cavity 211, the second positioning part 129c can be inserted into the first positioning part 250 first, so as to position the air duct module 100 and facilitate the installation of the air duct module 100.

[0215] Among them, the first positioning part 250 is arranged on the step surface 214, and the step surface 214 is higher than the bottom surface of the accommodation cavity 211. Since the overall appearance of the cabinet body 200 is generally a cuboid, after the electrical cavity 215 is arranged between the inner liner 221 and the outer shell 223, the inner liner 221 is not a regular cuboid, that is, a step surface 214 will be formed above the electrical cavity 215. By arranging the entire air duct module at this position, the existing structure of the horizontal freezer 10 can be utilized, and there is no need to separately set a step surface 214 higher than the bottom surface 213 in the accommodation cavity 211. This can not only improve the problem of blockage of the air return opening 114, but also reduce the number of components in the horizontal freezer 10 and reduce the occupation of the volume of the accommodation cavity 211.
