Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a refrigeration device. Background Technology

[0002] Refrigerators are an essential household appliance in people's daily lives. Because frost-free refrigerators are less likely to frost up inside, they currently occupy the main position in the refrigerator consumer market. Frost-free refrigerators need to be equipped with an air duct system to control the circulation of cold air.

[0003] In related technologies, dampers and air supply / return ducts are important structures for most refrigerators to achieve complete air circulation between different compartments. Some refrigerators embed structures such as air ducts and dampers in the foam layer of the refrigerator, resulting in an increase in the thickness of the foam layer. Especially for some multi-functional refrigerators, some functional structures are also embedded in the foam layer along with air ducts and dampers, which greatly increases the thickness of the foam layer and affects the storage capacity of the refrigerator. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a refrigeration device that integrates air ducts, dampers, and water injection pipes into a partition, thereby reducing the thickness of the foam layer and increasing storage space.

[0005] A refrigeration device according to an embodiment of the present invention includes a tank, a partition assembly, and functional components. The partition assembly includes a partition, an air damper, and a water injection pipe. The air damper and the water injection pipe are disposed on the partition. The partition is installed inside the tank and divides the tank into a first compartment and a second compartment. The functional components are disposed in the first compartment. The water injection pipe is used to connect the functional components. The partition is provided with an air duct that connects the first compartment and the second compartment. The air damper is disposed in the air duct.

[0056] This application provides a refrigeration device 10, which can be a refrigerator, freezer, or other similar equipment.

[0057] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigeration device according to an embodiment of the present invention. The refrigeration device 10 includes a tank 100, a partition assembly 200, a first air duct body 300, and a second air duct body 400.

[0058] The partition assembly 200 includes a partition 210 installed inside the inner chamber 100, dividing the inner chamber 100 into a first compartment 101 and a second compartment 102. By supplying different amounts of cooling to the first compartment 101 and the second compartment 102, the first compartment 101 and the second compartment 102 can be kept in different temperature environments, achieving different storage temperature zones within the same inner chamber 100 to meet the user's storage needs for different items. In one embodiment, the cooling temperature of the first compartment 101 is lower than that of the second compartment 102; the first compartment 101 serves as a freezer compartment, and the second compartment 102 can serve as a refrigerator compartment or a variable temperature compartment.

[0059] In one embodiment, the partition 210 is along the width direction of the bladder body 100 (i.e., Figure 1 Extending in the left-right direction, the partition 210 divides the bladder 100 into sections along the height direction of the bladder 100 (i.e., ...). Figure 1 The first compartment 101 and the second compartment 102 are arranged vertically in the middle. For ease of explanation, the compartment located below the partition 210 is defined as the first compartment 101, and the compartment located above the partition 210 is defined as the second compartment 102.

[0060] The first air duct 300 is located in the first compartment 101, and the second air duct 400 is located in the second compartment 102. For details, please refer to... Figure 2 , Figure 2 for Figure 1 A partial cross-sectional view of the refrigeration equipment along section AA shows that the first air duct body 300 and the rear wall of the bladder body 100 define a heat exchanger chamber 1011. A first storage chamber 1012 is formed on the side of the first air duct body 300 away from the rear wall of the bladder body 100. An evaporator 500 is disposed in the heat exchanger chamber 1011. The first air duct body 300 can send cold air from the heat exchanger chamber 1011 into the first storage chamber 1012. The second air duct body 400 can be used to send cold air into the second chamber 102.

[0061] To allow cold air from heat exchanger chamber 1011 to enter the second chamber 102, in this embodiment of the invention, partition 210 is provided with an air duct connecting the first chamber 101 and the second chamber 102. The refrigeration equipment 10 can use the air duct to deliver and return cold air to the second chamber 102. (Please refer to...) Figure 2 And refer to Figure 3 , Figure 3 for Figure 1 A partial sectional view of the refrigeration equipment along section BB shows that the air duct may include a supply air duct 210a and a return air duct 210b. Both the supply air duct 210a and the return air duct 210b connect the first chamber 101 and the second chamber 102. The cold air in the heat exchanger chamber 1011 can be sent into the second chamber 102 through the supply air duct 210a to cool the second chamber 102. At the same time, the air in the second chamber 102 that has undergone heat exchange can be returned to the heat exchanger chamber 1011 through the return air duct 210b to achieve air return.

[0062] In this embodiment of the invention, by setting an air duct in the partition 210, that is, the air duct is integrated into the partition 210, compared with the traditional refrigerator that pre-embeds pipes in the foam layer for air supply and return, there is no need to bury pipes in the foam layer, which reduces the thickness of the foam layer. Moreover, the air duct is set up using the space inside the partition 210, and does not occupy the internal space of the liner 100, which can increase the storage space of the refrigeration equipment 10.

[0063] Please combine Figure 2 And refer to Figure 4 , Figure 4 This is a schematic diagram of the partition assembly according to an embodiment of the present invention. The partition assembly 200 also includes a damper 220, which is disposed within an air duct. The damper 220 is used to control the opening or closing of the air duct, thereby controlling the communication state between the first compartment 101 and the second compartment 102. For example, the damper 220 can be disposed within an air supply duct 210a. The damper 220 can open or close the air supply duct 210a according to cooling requirements. Specifically, when cooling is required for the second compartment 102, the damper 220 opens the air supply duct 210a, allowing cold air to enter the second compartment 102 through the air supply duct 210a. When cooling is not required for the second compartment 102, the damper 220 closes the air supply duct 210a, preventing cold air from entering the second compartment 102.

[0064] By placing the damper 220 within the air duct of the partition 210, i.e., integrating the damper 220 into the partition 210, compared to some refrigerators in related technologies where the damper is embedded in the foam layer along with the air duct, the thickness of the foam layer is reduced, which can further improve the volume ratio of the storage space of the refrigeration equipment 10.

[0065] The refrigeration equipment 10 also includes functional components housed within the first compartment 101. These functional components may include, but are not limited to, an ice maker and an atomizing device. For example, if the functional component is an ice maker, it can utilize the cold air within the first compartment 101 to freeze the collected water into ice cubes, thus achieving the ice-making function. If the functional component is an atomizing device, it can spray water mist onto the food stored in the first compartment 101 as needed, using the cold air within the first compartment 101 to form a layer of ice on the food, thereby achieving the freezing and preservation function. The following explanation will use an ice maker as an example.

[0066] To supply water to the ice maker, such as Figure 4 As shown, the partition assembly 200 also includes a water injection pipe 240, which is used to connect to the ice maker. In this embodiment of the invention, the water injection pipe 240 is disposed on the partition 210, that is, the water injection pipe 240 is integrated into the partition 210.

[0067] By integrating the water inlet pipe 240 into the partition 210, instead of burying the entire water inlet pipe within the foam layer as in some refrigerators of the same technology, the thickness of the foam layer can be reduced, thus increasing storage space. Furthermore, integrating the water inlet pipe 240 into the partition simplifies its assembly. For example, the water inlet pipe 240 can be installed as a single unit with the partition 210. During the assembly of the refrigeration equipment 10, the water inlet pipe 240 can be installed together with the partition 210 into the inner tank 100, eliminating the need for separate installation of the water inlet pipe. This simplifies assembly and improves production efficiency.

[0068] The partition assembly 200 of this invention includes a partition 210 with an air duct, an air damper 220, and a water injection pipe 240. These components are integrated into the partition 210. Compared to some refrigerators in related technologies where all these components are embedded within the foam layer, this reduces the thickness of the foam layer. Furthermore, these components can be arranged using the space within the partition 210 itself, without additionally occupying space inside the liner 100, thus increasing the storage space of the refrigeration equipment 10. Moreover, by integrating the air duct, air damper 220, and water injection pipe 240 into the partition 210, the integration of the partition assembly 200 is improved, and the number of components is reduced. Simultaneously, the air duct, air damper 220, and water injection pipe 240 can be installed into the liner 100 along with the partition 210, reducing the assembly steps required for separate installation of individual parts and improving the production efficiency of the refrigeration equipment 10.

[0069] In one embodiment, please refer to Figure 5 , Figure 5 for Figure 1 A cross-sectional view of the refrigeration equipment along section CC shows that the air ducts include supply air duct 210a and return air duct 210b, which are arranged along the width direction of the bladder 100.

[0070] By arranging the supply air duct 210a and return air duct 210b along the width direction of the duct body 100, that is... Figure 5 Instead of arranging them along the front and back of the duct 100, the air supply duct 210a and return air duct 210b are arranged in the left and right direction, so that they can make full use of the same layer of space inside the partition 210. For example, both the air supply duct 210a and return air duct 210b are set close to the rear wall 110 of the duct 100, so that the air supply duct 210a and return air duct 210b use the rear space of the second chamber 102 for air supply and return, so that the front and middle space of the second chamber 102 can be used entirely for storing items, thereby improving the effective utilization rate of the space of the second chamber 102 and increasing the effective storage volume.

[0071] In one embodiment, please refer to the reference Figure 2 and Figure 3 The first air duct body 300 is provided with a first air supply cavity 310 and a return air cavity 320. The first air supply cavity 310 and the return air cavity 320 are located on the same side of the heat exchanger chamber 1011. The first air supply cavity 310 is connected to the air supply duct 210a, and the return air cavity 320 is connected to the return air duct 210b.

[0072] Understandably, both the first air supply chamber 310 and the return air chamber 320 are connected to the heat exchanger chamber 1011. Cold air in the heat exchanger chamber 1011 can be sent into the second chamber 102 through the first air supply chamber 310 and the air supply duct 210a to cool the second chamber 102. The air in the second chamber 102 that has undergone heat exchange flows back into the heat exchanger chamber 1011 through the return air duct 210b and the return air chamber 320. Of course, the first air duct body 300 is provided with a first air outlet (not shown). The first air supply chamber 310 is connected to the first storage chamber 1012 through the first air outlet. Cold air in the heat exchanger chamber 1011 is sent into the first storage chamber 1012 through the first air supply chamber 310 and the first air outlet.

[0073] Since the partition 210 integrates the return air duct 210b, this embodiment designs the first air duct body 300 in conjunction with the partition 210. By setting the return air cavity 320 in the first air duct body 300, that is, the first air duct body 300 integrates the return air cavity 320, the air after heat exchange in the second compartment 102 is returned through the first air duct body 300. Compared with the traditional refrigerator that embeds the return air cavity in the foam layer, the thickness of the foam layer is further reduced, thereby increasing the internal space of the inner chamber 100 without changing the overall volume of the refrigeration equipment 10, which can increase the storage space.

[0074] Furthermore, since the above embodiments arrange the return air duct 210b and the supply air duct 210a along the width direction of the heat exchanger chamber 100, this embodiment also designs the positions of the first supply air chamber 310 and the return air chamber 320 in conjunction with the return air duct 210b and the supply air duct 210a, so that the first supply air chamber 310 and the return air chamber 320 are also arranged along the width direction of the heat exchanger chamber 100, and the first supply air chamber 310 and the return air chamber 320 are both located on the same side of the heat exchanger chamber 1011, that is, the first supply air chamber 310... Both the return air cavity 320 and the return air cavity 320 are located on the front side of the evaporator 500. Compared to some refrigerators in related technologies that place the return air duct on the rear side (i.e., the back) of the evaporator, there is no need to reserve installation space on the rear side of the evaporator 500. Furthermore, the return air cavity 320 utilizes the internal space of the first air duct body 300. The arrangement of the return air cavity 320 does not require additional internal space of the liner 100. Therefore, the extra space due to the reduced foam layer thickness can be used for storage, thereby effectively increasing the storage space of the refrigeration equipment 10. In addition, compared to some refrigerators in related technologies that place the return air cavity on the left / right side of the evaporator, the return air cavity 320 does not require the installation space of the evaporator 500, and there is no need to reduce the size of the evaporator 500, ensuring that the evaporator 500 has sufficient heat exchange area and can guarantee the refrigeration efficiency of the refrigeration equipment 10.

[0075] In one embodiment, please refer to the reference Figure 3 and Figure 5 The second air duct body 400 is provided with a second air supply cavity 410 and a second air outlet (not shown) connected to the second air supply cavity 410. The second air duct body 400 is connected to the air supply duct 210a through the second air supply cavity 410. The cold air in the heat exchanger chamber 1011 is sent into the second chamber 102 through the first air supply cavity 310, the air supply duct 210a, the second air supply cavity 410, and the second air outlet.

[0076] In one embodiment, reference Figure 5 As shown, the second air duct body 400 protrudes from the rear wall 110 of the bladder body 100, and the return air duct 210b is disposed on at least one side of the second air duct body 400 along the width direction of the bladder body 100.

[0077] Along the width direction of the gallbladder body 100, i.e. Figure 5In the left-right direction, the second air duct body 400 only protrudes from the middle part of the rear wall 110 of the duct body 100. There is space on the left and right sides of the second air duct body 400. In this embodiment, the return air duct 210b is set on at least one side of the second air duct body 400 along the width direction of the duct body 100, that is, the return air duct 210b is located on the left and / or right side of the second air duct body 400, which improves the utilization rate of the space in the second compartment 102. Moreover, since the space above the partition 210 corresponding to the position of the return air duct 210b is used for the return air to enter, there must be no obstruction in the space above the return air duct 210b. In this embodiment, by setting the return air duct 210b on the left or right side of the second air duct body 400, the space on the left and right sides of the second air duct body 400 is used for return air, without occupying the storage space on the front side of the second air duct body 400. This allows the space in front of the first return air duct 210b to be used entirely for storing items, which can increase the effective storage volume of the second compartment 102.

[0078] In one embodiment, please refer to Figure 6 , Figure 6 This is a cross-sectional view of the partition assembly according to an embodiment of the present invention. The partition 210 includes an upper cover 211 and a lower cover 212. The upper cover 211 has a first protrusion 2111 protruding from the side opposite to the lower cover 212, and the lower cover 212 has a second protrusion 2121 protruding from the side facing the upper cover 211. Both the first protrusion 2111 and the second protrusion 2121 are constructed as cylindrical structures with open ends. The first protrusion 2111 and the second protrusion 2121 are joined together to form the aforementioned air supply duct 210a. The bottom end of the second air duct body 400 is connected to the first protrusion 2111. Specifically, a first channel is formed inside the first protrusion 2111, and a second channel is formed inside the second protrusion 2121. The first channel and the second channel communicate with each other to form the air supply duct 210a.

[0079] In one embodiment, the damper 220 is installed in the first channel of the first protrusion 2111. By forming the first protrusion 2111 through the protrusion of the upper cover 211 (making the partition 210 partially thicker), and installing the damper 220 in the first protrusion 2111, the damper 220 utilizes the space formed by the upward protrusion of the upper cover 211 for installation. It is not necessary to make the partition 210 very thick as a whole for installing the damper 220. Moreover, the first protrusion 2111 is used to connect with the second air duct 400. The upward protrusion of the first protrusion 2111 utilizes the space originally used for the installation of the second air duct 400 (equivalent to making the height of the second air duct 400 smaller to leave space for the first protrusion 2111). Thus, it does not occupy additional storage space in the second compartment 102. Therefore, in this embodiment, through the above arrangement, it is not necessary to make the partition 210 as a whole thicker, which can effectively increase the storage space.

[0080] It should also be noted that a mating surface is formed at the connection between the second air duct body 400 and the first protrusion 2111. In this embodiment, the damper 220 is set in the air supply duct 210a of the partition 210, specifically installed in the first protrusion 2111, rather than directly installed in the second air duct body 400. When the damper 220 is closed, the cold air is blocked by the damper 220 in the first channel of the first protrusion 2111. The cold air is located on the side of the mating surface away from the second air duct body 400, and the cold air will not enter the second air duct body 400 from the first channel. This effectively reduces the risk of cold air leaking from the connection between the partition 210 and the second air duct body 400 to the second compartment 102, prevents the temperature of the second compartment 102 from being affected, and avoids icing.

[0081] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the gallbladder 100 according to an embodiment of the present invention. The gallbladder 100 is provided with a mounting groove 130, which is recessed towards the outer side of the gallbladder 100. The mounting groove 130 may include a first groove portion recessed in the side wall 120 of the gallbladder 100 and a second groove portion recessed in the rear wall 110 of the gallbladder 100. The cross-sectional shape of the mounting groove 130 is approximately U-shaped. The partition 210 can be inserted along the mounting groove 130 and fully engaged into the gallbladder 100. The mounting groove 130 provides support and positioning for the partition 210, enabling the partition 210 to be quickly installed to the required design position.

[0082] To prevent the partition 210 from sliding out of the mounting groove 130, please refer to the reference. Figure 4 and Figure 7 A limiting part 2116 is provided on the side of the partition 210 facing the side wall 120 of the bladder 100, and a second limiting groove 150 is provided on the side wall 120 of the bladder 100, and the limiting part 2116 is inserted into the second limiting groove 150.

[0083] like Figure 4 As shown, the limiting part 2116 protrudes from the side surface of the partition 210, and the limiting part 2116 is located near the end of the partition 210 away from the rear wall 110 of the bladder 100. The second limiting groove 150 can be recessed into the bottom of the mounting groove 130. During installation, the limiting part 2116 deforms and gets stuck in the second limiting groove 150. The second limiting groove 150 restricts the degree of freedom of the limiting part 2116 to move in the front-back direction of the bladder 100, thereby restricting the movement of the partition 210 and making the partition 210 firmly installed in the mounting groove 130, preventing the partition 210 from sliding out of the mounting groove 130 due to vibration or tilting.

[0084] To further ensure that the partition 210 is securely installed in the mounting groove 130, in one embodiment, please refer to... Figure 4 and Figure 7A latch 2115 is provided on the partition 210 facing the rear wall 110 of the bladder body 100, and the partition 210 is engaged with the rear wall 110 of the bladder body 100 through the latch 2115. The number of latches 2115 can be one or more, and this embodiment does not limit this. Specifically, the latch 2115 has a protruding hook portion, and the rear wall 110 of the bladder body 100 has a locking hole 140. When the partition 210 is fully engaged in the mounting groove 130, the latch 2115 passes through the locking hole 140, causing the hook portion to abut against the outer surface of the rear wall 110 of the bladder body 100, thereby locking the partition 210 with the rear wall 110 of the bladder body 100 through the latch 2115, ensuring a firm connection between the partition 210 and the bladder body 100.

[0085] Understandably, since the cooling temperatures of the first chamber 101 and the second chamber 102 are different, an insulation layer (not shown in the figure) is provided inside the partition 210 to prevent the temperatures of the first chamber 101 and the second chamber 102 from affecting each other. The insulation layer serves to insulate and prevent heat transfer between the first chamber 101 and the second chamber 102. Specifically, the partition 210 includes an upper cover 211 and a lower cover 212. The upper cover 211 and the lower cover 212 are connected and enclose to form an insulation cavity (not shown). The insulation layer is disposed inside the insulation cavity and can be formed by foaming with foaming liquid filled inside the insulation cavity.

[0086] In one embodiment, reference Figure 4 As shown, the partition 210 has an injection port 210c on at least one side along its circumference, through which the foaming liquid can be injected into the insulation cavity. For example, a first injection port can be provided on the side of the partition 210 facing the rear wall 110 of the liner 100, and a second injection port can be provided on the side of the partition 210 facing the side wall 120 of the liner 100. The number of both the first and second injection ports can be multiple.

[0087] A foamed layer is provided on the outside of the tannery 100. In order to improve the production efficiency of the refrigeration equipment 10, the partition 210 can be foamed together with the foamed layer on the outside of the tannery 100 after being assembled into the tannery 100.

[0088] In one embodiment, please refer to Figure 7The inner chamber 100 is provided with a through hole 160. The above-mentioned liquid injection port 210c of the partition 210 is connected to the through hole 160. The heat insulation layer is connected to the foaming layer through the liquid injection port 210c and the through hole 160. Specifically, during the production process of the refrigeration equipment 10, the partition 210 is first installed inside the bladder 100, so that the liquid injection port 210c of the partition 210 is connected to the through hole 160 of the bladder 100. Then, the refrigeration equipment 10 is foamed. During the foaming process, the foaming liquid injected into the outside of the bladder 100 can flow into the interior of the partition 210 through the through hole 160 and the liquid injection port 210c. After the foaming liquid in the partition 210 expands and solidifies, it forms the above-mentioned heat insulation layer. The heat insulation layer is connected to the foaming layer on the outside of the bladder 100 through the liquid injection port 210c and the through hole 160 to form a whole. The heat insulation layer and the foaming layer play a restraining role on the partition 210, which can greatly enhance the firmness of the connection between the partition 210 and the bladder 100.

[0089] Furthermore, during the foaming process, the foaming liquid can seep into the space between the partition 210 and the mounting groove 130 of the inner chamber 100, filling the gap between the partition 210 and the groove wall of the mounting groove 130. This allows the partition 210 and the foaming layer to separate the upper and lower first chambers 101 and second chambers 102, preventing cold leakage between the first chamber 101 and second chamber 102.

[0090] The following is a detailed description of the specific structure of the water injection pipe 240 integrated into the partition 210. Please refer to [link / reference]. Figure 8 , Figure 8 This is a cross-sectional view of the water injection pipe and partition assembly according to an embodiment of the present invention. Part of the water injection pipe 240 is disposed within the insulation cavity of the partition 210, while another part extends outside the partition 210. Specifically, the end of the water injection pipe 240 furthest from the water source needs to extend into the first compartment 101 and connect to the ice maker. By placing part of the water injection pipe 240 inside the partition 210, the water injection pipe 240 utilizes the internal space of the partition 210, reducing the occupancy of storage space in the first compartment 101 or the second compartment 102.

[0091] To prevent the cold air from the first chamber 101 from being transferred to the water injection pipe 240 and freezing, at least a portion of the outer peripheral wall of the water injection pipe 240 is covered with a heating element (not shown in the figure). By covering the outer peripheral wall of the water injection pipe 240 with a heating element, the temperature of the water injection pipe 240 can be increased by heating the water injection pipe 240, preventing the water supply from freezing when flowing through the water injection pipe 240 and avoiding blockage of the water injection pipe 240. In one embodiment, the heating element is configured to generate heat when energized, and the heating element can be a heating wire or a heating foil.

[0092] Please combine Figure 8 And refer to Figure 9 , Figure 9The exploded view shows the assembly of the water injection pipe and the lower cover of the partition in an embodiment of the present invention. The lower cover 212 is provided with a first through hole 2122. The first through hole 2122 extends through the lower cover 212 along the thickness direction of the lower cover 212 and connects the heat preservation cavity and the first chamber 101. The water injection pipe 240 includes a first pipe portion 241, which passes through the first through hole 2122. The portion of the first pipe portion 241 extending out of the lower cover 212 is connected to the ice maker so that water is injected into the ice maker.

[0093] Since the insulation layer inside the insulation cavity is foamed together with the foaming layer outside the bladder 100, in order to prevent the foaming liquid from leaking into the first chamber 101 through the first through hole 2122, the first through hole 2122 and the first tube 241 need to have a good sealing assembly structure.

[0094] In one embodiment, please refer to Figure 10 , Figure 10 for Figure 8 The enlarged view at point D shows that the partition assembly 200 includes a seal 250, which includes a first sealing part 251. The first sealing part 251 is disposed between the wall of the first tube 241 and the first through hole 2122, and surrounds the outer peripheral wall of the first tube 241. The first sealing part 251 is used to seal the gap between the first tube 241 and the first through hole 2122.

[0095] Understandably, the first sealing part 251 is hollow and annular in design. A mating hole (not shown) is formed in the center of the first sealing part 251 for the first tube part 241 to pass through. The wall of the mating hole is interference-fitted with the outer peripheral wall of the first tube part 241, meaning they are tightly fitted, eliminating any gap between the first tube part 241 and the wall of the mating hole, thus preventing foaming liquid from leaking out between the first tube part 241 and the first sealing part 251. Correspondingly, the outer periphery of the first sealing part 251 and the wall of the first through hole 2122 can also be interference-fitted to eliminate any gap between them, preventing foaming liquid leakage.

[0096] To further improve sealing, please refer to [the relevant documentation / reference]. Figure 10 In one embodiment, the inner surface of the lower cover 212 is provided with a first annular protrusion 2117, and the first annular protrusion 2117 forms a first through hole 2122 (the inner wall of the first annular protrusion 2117 is the hole wall of the first through hole 2122). The sealing member 250 also includes a second sealing part 252, which is connected to the first sealing part 251 and is disposed around the outer peripheral wall of the first annular protrusion 2117.

[0097] With this configuration, the fit gap between the seal 250 and the first annular protrusion 2117 is inverted U-shaped, with multiple bends. The multiple bends significantly increase the difficulty for the foaming liquid to enter, thereby enhancing the sealing performance. If the foaming liquid is to enter and reach the inner wall between the first seal 251 and the first annular protrusion 2117, it must complete at least three bends and have sufficiently strong flow capacity. In reality, when the foaming liquid reaches the position of the first tube 241, its flowability has been greatly reduced. Therefore, the fit between the second seal 252 and the first annular protrusion 2117 can effectively prevent the foaming liquid from entering, effectively reducing the risk of foaming liquid leakage.

[0098] Please continue to refer to this. Figure 10 In one embodiment, the inner surface of the lower cover 212 is further provided with a second annular protrusion 2118, and the second sealing part 252 is disposed between the first annular protrusion 2117 and the second annular protrusion 2118, with the second annular protrusion 2118 surrounding the outer peripheral wall of the second sealing part 252.

[0099] Therefore, by setting the second annular protrusion 2118, the mating gap between the entire sealing element 250 and the first annular protrusion 2117 and the second annular protrusion 2118 is approximately an inverted S-shape, increasing the number of bends and thus further increasing the difficulty for the foaming liquid to enter, thereby further enhancing the sealing performance. Moreover, during the foaming process, the second annular protrusion 2118 can separate the outer peripheral wall of the second sealing part 252 from the foaming liquid, so that the foaming liquid only contacts the top of the sealing element 250, which can prevent the foaming liquid on the side from pushing the sealing element 250 up when it expands; at the same time, the foaming liquid on the top of the sealing element 250 exerts a compressive force on the sealing element 250, ensuring that the sealing element 250 is stably located between the first annular protrusion 2117 and the second annular protrusion 2118, ensuring the sealing effect.

[0100] Please combine Figure 8 , Figure 9 And refer to Figure 11 , Figure 11 This is a schematic diagram of the assembly of the water injection pipe and the lower cover of the partition in an embodiment of the present invention. The partition 210 includes a first fixing member 260, which is disposed in the heat preservation cavity and close to the first pipe 241. The first fixing member 260 is fixed to the upper cover 211 or the lower cover 212. The first fixing member 260 is provided with a slot 261, and the first fixing member 260 is engaged with the water injection pipe 240 through the slot 261.

[0101] By setting the first fixing member 260 to engage with the water injection pipe 240, the first fixing member 260 is stably and firmly installed on the partition plate 210, preventing the water injection pipe 240 from shaking due to external force or vibration. Especially during the foaming process, the expansion of the foaming liquid will exert a squeezing force on the water injection pipe 240. In this embodiment, the first fixing member 260 is set close to the first pipe section 241, which can ensure that the first pipe section 241 is firmly fixed, prevent the first pipe section 241 from being squeezed and displaced, ensure the sealing of the first pipe section 241 and the first through hole 2122, and prevent the foaming liquid from leaking out.

[0102] In one embodiment, the first fixing member 260 is fixed to the lower cover 212 to facilitate the engagement of the first fixing member 260 with the first tube portion 241. It is understood that there can be various methods for fixing the first fixing member 260 to the lower cover 212. The first fixing member 260 can be fixed to the lower surface of the lower cover 212 through a connecting structure, or it can be integrally injection molded with the lower cover 212 using an injection molding process. This embodiment does not limit the specific method used.

[0103] Please refer to Figure 8 A second through hole 2112 is provided on the side of the partition 210 facing the rear wall 110 of the tank 100. The water injection pipe 240 includes a second pipe portion 242, which passes through the second through hole 2112. Understandably, the portion of the second pipe portion 242 extending out of the partition 210 is used to connect with the upstream water supply pipe.

[0104] A limiting member 2113 is provided on the side of the partition 210 facing the rear wall 110 of the bladder body 100. The limiting member 2113 is provided with a first limiting groove 2114. The limiting member 2113 surrounds part of the outer peripheral wall of the second tube section 242 through the first limiting groove 2114.

[0105] The first limiting groove 2114 is roughly fitted to the outer peripheral wall of the second pipe section 242. The groove wall of the first limiting groove 2114 is arc-shaped, which can limit the second pipe section 242. The limiting member 2113 restricts the degree of freedom of the second pipe section 242 to move laterally (i.e., the degree of freedom of movement along the width direction of the bladder body 100) through the first limiting groove 2114, preventing the second pipe section 242 from shifting. Thus, the limiting member 2113 limits the second pipe section 242, and the first fixing member 260 fixes the part near the first pipe section 241. The cooperation of the limiting member 2113 and the first fixing member 260 enhances the firmness of the assembly between the water injection pipe 240 and the partition 210, preventing the water injection pipe 240 from shaking due to external force or vibration.

[0106] In one embodiment, the partition assembly 200 further includes a second fixing member 270, which is fixed to the upper cover 211 or the lower cover 212. The second fixing member 270 is provided with a limiting hole 271, and the second tube 242 passes through the limiting hole 271.

[0107] The limiting hole 271 restricts the degree of freedom of the second tube 242 to move along the height direction of the bladder 100 (i.e., restricts the vertical movement of the second tube 242) and the degree of freedom of movement of the second tube 242 along the width direction of the bladder 100 (i.e., restricts the lateral movement of the second tube 242), further preventing the second tube 242 from shifting. Through the cooperation of the first fixing member 260, the second fixing member 270 and the limiting member 2113, the firmness and stability of the assembly of the water injection pipe 240 and the partition 210 are greatly enhanced, preventing the water injection pipe 240 from shaking due to external force or vibration.

[0108] In one embodiment, please refer to Figure 6 The partition assembly 200 also includes a heat insulation element 230, which is disposed in the air supply duct 210a. The heat insulation element 230 is provided with a receiving groove 231 and an air passage 232 communicating with the receiving groove 231. A damper 220 is installed in the receiving groove 231 and is used to cover or expose the air passage 232.

[0109] By installing a heat insulation component 230 within the air supply duct 210a, the heat insulation component 230 isolates the high-temperature environment of the second compartment 102 from the low-temperature environment of the first compartment 101, preventing the storage temperatures of the first compartment 101 and the second compartment 102 from affecting each other through the air supply duct 210a. Furthermore, by installing the damper 220 within the receiving groove 231 of the heat insulation component 230, condensation at the damper 220 can be reduced, mitigating the tendency for icing at the damper 220 and preventing interference with its normal operation. Moreover, the heat insulation component 230 can be made of materials such as heat-insulating foam, resulting in better sealing between the damper 220 and the heat insulation component 230 compared to directly assembling the damper 220 to the air supply duct 210a of the partition 210. When the damper 220 is closed, it effectively prevents cold air from entering the second air duct body 400.

[0110] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
