[0052] A freezer is a professional storage tool used to store 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 the 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.

[0053] In order to improve the uniformity of the temperature inside the freezer, the air-cooled method can be used for refrigeration. The cold air is circulated to each corner through a fan to ensure that food and beverages can maintain approximately the same temperature throughout the freezer, avoiding the situation of too high or too low local temperature.

[0054] In the related art, a fan is integrated into a duct module. Since the duct module needs to blow cold air into the freezer, the duct module needs to be fixed inside the freezer, which may cause the fixing parts to be exposed. When the user opens the freezer, the fixing parts are exposed, affecting the appearance neatness. The duct module provided by the embodiment of the present application can solve the above problems. The duct module and the horizontal freezer provided by the embodiment of the present application can solve the above problems. The duct module and the horizontal freezer provided by the embodiment of the present application can make the appearance of the entire duct module neat.

[0055] The present application will be described below in conjunction with the drawings and specific embodiments:

[0056] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a duct module 100. The duct module 100 provided by the embodiment of the present application is applied to a refrigeration device. The duct module 100 provided by the embodiment of the present application can make the appearance of the entire duct module 100 neat.

[0057] Among them, the refrigeration device can be a refrigerator or a freezer. Specifically, the freezer can be a horizontal freezer 10 or a vertical freezer.

[0058] In the embodiment of the present application, the duct module 100 includes: a housing 120, a diversion member 130, a fixing member 150, and a cover plate 160. The housing 120 has an installation cavity 124. The diversion member 130 is installed in the installation cavity 124. The housing 120 has an installation groove 128; the fixing member 150 is disposed in the installation groove 128 and is used for fixedly connecting the housing 120 to the cabinet body 200 of the refrigeration device. The cover plate 160 covers the installation groove 128.

[0059] The duct module 100 is applied to a refrigeration device and is installed in the cabinet body 200 of the refrigeration device, which can make the air in the refrigeration device flow, so that the air in the refrigeration device can be blown to the frozen items after being refrigerated by the evaporator 320. That is, it can be considered that the duct module 100 is mainly used to blow cold air into the refrigeration device, so that the cold air can circulate inside the refrigeration device, and as much as possible to ensure that the temperature in the same chamber of the refrigeration device is roughly the same, reducing the temperature difference in the same chamber.

[0060] The housing 120 is the main body 220 of the entire duct module 100 and is the basic component of the duct module 100, which can provide an installation basis for other structures of the duct module 100. Structures such as the diversion member 130 can be installed on the housing 120, so that the duct module 100 can form a whole, which is convenient for the installation and transportation of the duct module 100. At the same time, the housing 120 can also play a protective role for structures such as the diversion member 130, and can reduce the damage of external structures to the diversion member 130, etc.

[0061] The flow guide 130 is mainly used for disturbing the flow so that the air can circulate in the refrigeration device, that is, the air in the refrigeration device can continuously flow to the evaporator 320, and then be blown to the frozen items again after being cooled by the evaporator 320.

[0062] 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 guide member 130 is installed inside the installation cavity 124 and the air duct module 100 is fixed to the refrigeration equipment, the guide member 130 will not be exposed to the outside, which can avoid damage to the guide member 130 during the assembly of the air duct module 100 as much as possible.

[0063] Of course, in some other embodiments, the installation cavity 124 and the installation groove 128 may also be partially connected, and there is no specific limitation on this.

[0064] In the embodiment of the present application, for the convenience of description, the height direction, width direction X and thickness direction Y of the shell 120 are defined. As shown in the figure, the mounting groove 128 can be set at the top of the entire shell 120. In the process of installing the air duct module 100 to the refrigeration equipment, the mounting groove 128 is set close to the door body 230 of the refrigeration equipment, that is, the mounting groove 128 is closest to the door body 230 of the refrigeration equipment. During installation, after the door body 230 is opened, it is convenient for the fixing part 150 to pass through the shell 120 and the cabinet body 200 of the refrigeration equipment, thereby facilitating the assembly of the air duct module 100.

[0065] In an embodiment of the present application, the fixing member 150 is arranged in the mounting groove 128 and can fix the shell 120 and the cabinet 200, and the cover 160 covers the mounting groove 128, which can shield the fixing member 150 in the mounting groove 128, so that the cover 160 and the shell 120 can form a whole, and the fixing member 150 can be hidden in the mounting groove 128, avoiding the fixing member 150 from being exposed, so that the appearance of the entire air duct module 100 is neat.

[0066] In addition, the cover 160 shields the fixing member 150 in the installation groove 128 to prevent the fixing member 150 from being exposed, and can also reduce the corrosion of the fixing member 150 due to the low temperature or condensed water in the refrigeration equipment, and can also increase the service life of the fixing member 150.

[0067] See also Figure 3 In some embodiments, the shell 120 is provided with a fixing hole 129a, which is connected to the installation groove 128. Part of the fixing member 150 is accommodated in the installation groove 128, and part of the fixing member 150 is passed through the fixing hole 129a for fixed connection with the cabinet 200.

[0068] 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 penetrates through the fixing hole 129a and is fixedly connected to the cabinet body 200.

[0069] 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 be provided or not provided on the inner wall of the fixing hole 129a. During the assembly process, the fixing member 150 is first inserted into the fixing hole 129a, and then the fixing member 150 is rotated so that the fixing member 150 can be locked in the cabinet body 200.

[0070] It should be noted that the air duct module 100 is installed in the cabinet body 200 and placed on the bearing surface. The fixing member 150 only plays a fixing role and basically does not bear the gravity of the air duct module 100.

[0071] 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, so that the cover plate 160 is snap-connected to the housing 120, and then the cover plate 160 is installed on the housing 120.

[0072] As for the way of snap-connection 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 made.

[0073] Taking the example that the snap-connection portion 162 is provided on the cover plate 160 and the snap-connection hole 129b is provided on the housing 120 for specific illustration. The snap-connection portion 162 is provided below the cover plate 160. After the cover plate 160 is snap-connected to the housing 120, the cover plate 160 can also block the snap-connection portion 162, which can prevent the connection position of the snap-connection portion 162 and the snap-connection hole 129b from being exposed, and can improve the appearance beauty of the entire air duct module 100.

[0074] Please refer to Figure 3 and Figure 4 , specifically, the snap-connection portion 162 can include a connection segment 162a and a snap-connection segment 162b. One end of the connection segment 162a is connected to the cover plate 160, and the other segment is connected to the snap-connection segment 162b. The connection segment 162a penetrates through the snap-connection hole 129b, and the snap-connection segment 162b abuts against the side of the snap-connection hole 129b away from the cover plate 160, so that the cover plate 160 can be snap-connected to the housing 120.

[0075] Among them, multiple engaging portions 162 and engaging holes 129b can be provided. For example, if the cover plate 160 is rectangular, at least one engaging portion 162 can be provided on each side of the cover plate 160. Correspondingly, multiple engaging holes 129b are also provided, and one engaging portion 162 is engaged with one engaging hole 129b. The number of engaging portions 162 and engaging holes 129b can be set according to actual situations, and the specific number can be not limited.

[0076] Please refer to Figure 5 and Figure 6 , 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.

[0077] Among them, the housing 120 can 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 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 an installation cavity 124.

[0078] 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, disposing the installation groove 128 on the rear housing 123 can facilitate the assembly between the rear housing 123 and the cabinet 200.

[0079] In some embodiments, the rear housing 123 includes a main body 123a and a fixing portion 123b protruding from the main body 123a, and the installation groove 128 is provided on 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 housing 121. Of course, in order to adapt to the fixing portion 123b, a groove 121d can be provided on the front housing 121, and the fixing portion 123b can be disposed in the groove 121d.

[0080] Since the thickness of the main body 123a is very thin and an installation groove 128 capable of accommodating the fixing member 150 cannot be directly formed on the main body 123a, the installation groove 128 can be provided on the fixing portion 123b, which can set an installation groove 128 capable of accommodating the fixing member 150 without increasing the thickness of the rear housing 123, simplifying the process and the structure is also relatively simple.

[0081] Specifically, the main body 123a and the fixing portion 123b can be integrally formed, so as to reduce the manufacturing process of the entire rear housing 123 and reduce the manufacturing cost of the housing 120.

[0082] In some embodiments, the cover plate 160 is snap-fitted 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 snap-fitting of the cover plate 160 to both the front shell 121 and the rear shell 123 can improve the stability of the fixation of the cover plate 160 and reduce the risk of the cover plate 160 detaching.

[0083] Of course, in addition to this, it can also be that the cover plate 160 is only snap-fitted to the front shell 121, or it can be that the cover plate 160 is only snap-fitted to the rear shell 123. The snap-fitting methods of the cover plate 160 to the front shell 121 and the rear shell 123 can be the same or different, and no specific limitation is required.

[0084] The above 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-fitted to the rear shell 123. As for the specific snap-fitting method, it can be that snap holes are provided on the front shell 121 and snap portions are provided on the rear shell 123, and the snap holes and the snap portions are snap-fitted. 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-fitted.

[0085] 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.

[0086] 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 1 ), and the connecting member 170 passes through the first connection hole and the second connection hole.

[0087] The connecting member 170 can be a screw or a nut. Threads can be provided on the inner walls of the first connection hole and the second connection hole, and the front shell 121 and the rear shell 123 are locked through the connecting member 170.

[0088] It should be noted that the above introduced 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, it can be that both the snap-fitting and the connecting member 170 connect the front shell 121 and the rear shell 123, or it can be that the front shell 121 and the rear shell 123 are only connected by snap-fitting, or it can be that the front shell 121 and the rear shell 123 are only connected by the connecting member 170. The specific method can be not limited.

[0089] In some embodiments, the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 includes a first housing segment 121a, a second housing segment 121b, and a third housing segment 121c. The second housing segment 121b connects the first housing segment 121a and the third housing segment 121c respectively. The rear housing 123 is connected to the first housing segment 121a to form an installation cavity 124. The second housing segment 121b and the third housing segment 121c are used to form a fixing cavity 125 for installing the evaporator 320 with the cabinet body 200. Among them, the first air outlet 112 and the second air outlet 113 are provided on the first housing segment 121a, and the air return port 114 is provided on the third housing segment 121c.

[0090] 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 segment 121a, a second housing segment 121b, and a third housing segment 121c. The first housing segment 121a is located above the second housing segment 121b, and the second housing segment 121b is located above the third housing segment 121c. The first housing segment 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, and the air return port 114 is provided on the third housing segment 121c and is communicated with the fixing cavity 125.

[0091] Among them, when the air in the accommodation cavity 211 enters the fixing cavity 125 through the air return port 114, under the action of the drainage member 130, it will flow towards the air inlet 115, so that the air entering the fixing 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 and the second air outlet 113. That is to say, the evaporator 320 is arranged between the air return port 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 and the second air outlet 113 is always cold air, improving the refrigeration effect.

[0092] It should be noted that the evaporator 320 is fixed in the fixing cavity 125 jointly formed by the second housing segment 121b, the third housing segment 121c and the cabinet body 200, which can facilitate 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 of the accommodation cavity 211, and then assemble the whole air duct module 100 into the accommodation cavity 211, so that the second housing segment 121b and the third housing segment 121c cover the evaporator 320, forming a closed fixing cavity 125 with the main body 220, so that the air in the accommodation cavity 211 can enter the fixing cavity 125 through the air return port 114, flow through the evaporator 320 for refrigeration and then flow to the first air outlet 112.

[0093] In some embodiments, the third housing segment 121c protrudes from the second housing segment 121b, and the air return opening 114 is provided at one end of the third housing segment 121c away from the second housing segment 121b.

[0094] The fact that the third housing segment 121c protrudes from the second housing segment 121b means that in the width direction X, the third housing 120 protrudes from the second housing segment 121b. 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 provided at one end of the third housing segment 121c away from the second housing segment 121b and the first air outlet 112 is provided 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 and improving the refrigeration effect on the air, and further improving the freezing effect.

[0095] Please refer to Figure 1 and Figure 2 , in some embodiments, the housing 120 further includes a heat insulation layer 126. The heat insulation layer 126 is disposed in the installation cavity 124 and is adhered to the front housing 121. Since the air in the installation cavity 124 is cooled by the evaporator 320, the temperature is relatively low and there is a certain temperature difference from the accommodation cavity 211. By providing the heat insulation layer 126 on the inner side of the front housing 121, the temperature of the front housing 121 can be kept substantially consistent with the temperature of the accommodation cavity 211, thereby reducing the risk of condensation on the front housing 121 due to the temperature difference between the inside and outside.

[0096] In addition, the housing 120 further includes a sealing layer 127. The sealing layer 127 is disposed at the connection between the front housing 121 and the rear housing 123 for sealing the front housing 121 and the rear housing 123.

[0097] Please refer to Figure 7 and Figure 8 , based on the same inventive concept, the embodiment of the present application further provides a horizontal freezer 10. The horizontal freezer 10 includes a cabinet 200 and the above-mentioned air duct module 100. The air duct module 100 is installed in the cabinet 200.

[0098] The horizontal freezer 10 is mainly used for refrigerating items. The cabinet 200 is the main body 220 structure of the entire horizontal freezer 10, which can provide an installation basis for structures such as the air duct module 100, the compressor 310, the evaporator 320, and the condenser, and can also play a role in protecting the above-mentioned electronic components.

[0099] 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 accommodation cavity 211 is arranged inside the main body 220, and the items to be refrigerated are arranged in the accommodation cavity 211. The cold air blown out by the air duct module 100 freezes the items. The main body 220 includes an inner liner 221 and an outer shell 223. The space between the inner liner 221 and the outer shell 223 is filled with a foaming layer. There is an electrical appliance cavity 215 for accommodating the compressor 310 between the inner liner 221 and the outer shell 223, and the electronic control box 340 is also arranged in the electrical appliance cavity 215.

[0100] 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 defined respectively. 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. The air duct module 100 is arranged on one side of the width direction X.

[0101] Please refer to Figure 9 , in some embodiments, a strengthening part 240 is arranged on the cabinet body 200, and the fixing part 150 is fixedly connected to the housing 120 and the strengthening part 240.

[0102] 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 and improves the fixing effect of the fixing part 150.

[0103] Please refer to Figure 10 , 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.

[0104] 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.

[0105] Among them, the first positioning portion 250 is disposed 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 200 is generally a cuboid, after the electrical cavity 215 is provided 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 disposing 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 provide 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 return air port 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.

[0106] Please refer to Figure 11 and Figure 12 , in some embodiments, the housing 110 is provided with a return air port 114, and the second positioning portion 129c includes a connecting section 129d and a positioning section 129e connected to the connecting section 129d. The connecting section 129d is connected to the housing 120 and is located at the return air port 114.

[0107] Among them, the connecting section 129d is connected to the third housing section 121c and is disposed inside the third housing section 121c. Since the return air port 114 is provided on the side wall of the third housing section 121c, the connecting section 129d can be connected to the grille ribs of the return air port 114, thereby increasing the connection strength of the connecting section 129d and improving the strength of the entire second positioning portion 129c.

[0108] There may be multiple connecting sections 129d, and the multiple connecting sections 129d are all connected to the positioning section 129e, which can increase the strength of the positioning section 129e and reduce the risk of fracture of the entire second positioning portion 129c.

[0109] Please refer to Figure 13 and Figure 14 , in some other embodiments, the housing 120 is provided with a return air port 114, the second positioning portion 129c includes a connecting section 129d and a positioning section 129e connected to the connecting section 129d. A connecting plate 129f is provided on the lower end surface of the housing 120, and the connecting plate 129f is respectively connected to both sides of the housing 120. The connecting section 129d is connected to the connecting plate 129f, and the connecting section 129d is located at the grille ribs of the return air port 114.

[0110] The connecting plate 129f is arranged below the third housing segment 121c. Since the connecting plate 129f is arranged below the third housing segment 121c and is connected to the lower edge of the third housing segment 121c, that is, the connecting plate 129f can be parallel to the air inlet direction of the air return port 114 and will not block the air return area of the air return port 114. The connecting section 129d is arranged at the grille ribs of the air return port 114, and the grille ribs are used to fix the connecting section 129d, so that the connecting section 129d will not block the air return area of the air return port 114, and thus the air return volume can be increased.
