Description

Technical Field

[0001] This application belongs to the technical field of electrical appliances, and particularly relates to a horizontal freezer. Background Art

[0002] With the continuous increase in the demand for refrigeration and freezing equipment in commerce and households, horizontal dual-temperature freezers are widely popular because they can meet the storage functions of different temperature requirements simultaneously. However, currently, horizontal dual-temperature freezers on the market generally use the coil winding method to control the temperatures of the freezer compartment and the refrigerator compartment. Among them, the temperature of the freezer compartment is adjusted by controlling the start and stop of the compressor, while the temperature of the refrigerator compartment is indirectly controlled by adjusting the number of coil windings and the coil winding spacing.

[0003] However, in the prior art, since the refrigerator compartment and the freezer compartment share a set of coil winding systems, the temperature control of the refrigerator compartment is directly subject to the refrigeration demand of the freezer compartment. When the freezer compartment needs to cool down quickly, the refrigerator compartment will also be greatly affected, resulting in large temperature fluctuations in the refrigerator compartment, unstable temperature in the refrigerator compartment, affecting the freshness preservation effect of the stored items, and thus causing customer complaints. Summary of the Utility Model

[0004] To solve the above technical problems, the present utility model provides a horizontal freezer, aiming to at least solve the technical problem of unstable temperature in the refrigerator compartment to a certain extent.

[0005] The technical solution of the present utility model is as follows:

[0006] A horizontal freezer, characterized in that it includes: an inner container; a partition member disposed inside the inner container to form a refrigerator compartment and a freezer compartment, and the partition member is provided with an air supply channel and a return air channel communicating with the refrigerator compartment; an air duct module disposed inside the freezer compartment and having an air supply port communicating with the freezer compartment, a return air port communicating with the freezer compartment, a first communication port communicating with the air supply channel, and a second communication port communicating with the return air channel; an evaporator disposed inside the freezer compartment and used for heat exchange with the air in the air duct module.

[0007] Since the partition is disposed inside the inner container to form a refrigerating chamber and a freezing chamber, the partition is provided with an air supply channel and a return air channel communicating with the refrigerating chamber. The air duct module is disposed inside the freezing chamber and has an air supply port communicating with the freezing chamber, a return air port communicating with the freezing chamber, a first communication port communicating with the air supply channel, and a second communication port communicating with the return air channel. The evaporator is disposed inside the freezing chamber and is used for exchanging heat with the air inside the air duct module. Therefore, the air duct module can send the air that has exchanged heat with the evaporator into the refrigerating chamber through the first communication port and the air supply channel, and then send the hot air inside the refrigerating chamber to the evaporator through the return air channel and the second communication port to exchange heat with the evaporator, so as to maintain a constant low temperature environment inside the refrigerating chamber, realizing an independent path for the air circulation in the refrigerating chamber, ensuring that the refrigerating chamber can be temperature-controlled independently of the freezing chamber, improving the accuracy and stability of temperature control, and ensuring the stability of the temperature inside the refrigerating chamber. Moreover, since the refrigerating chamber and the freezing chamber are physically separated by the partition, and the air circulation in the refrigerating chamber does not directly depend on the refrigeration effect of the freezing chamber, the direct contact opportunity between the wet air inside the refrigerating chamber and the cold surface inside the freezing chamber is reduced. At the same time, the temperature of the air inside the air duct module is precisely controlled after exchanging heat with the evaporator, reducing the possibility of condensate water forming on the surface of the inner container, thereby effectively avoiding the problem of frosting on the inner container. The air duct module can send the air that has exchanged heat with the evaporator into the freezing chamber through the air supply port, and then send the hot air inside the freezing chamber to the evaporator through the return air port to exchange heat with the evaporator, so as to maintain a constant low temperature environment inside the freezing chamber, realizing an independent path for the air circulation in the freezing chamber, making the temperature control of the freezing chamber and the temperature control of the refrigerating chamber independent of each other, improving the accuracy and stability of temperature control, and ensuring the stability of the temperature inside the freezing chamber.

[0008] In some embodiments, the air duct module is disposed at an angle with the partition to facilitate the arrangement of the air duct module.

[0009] In some embodiments, the air duct module is located on one side in the thickness direction of the inner container, and the partition is disposed along the thickness direction of the inner container to facilitate the communication between the first communication port and the air supply channel and the communication between the second communication port and the return air channel.

[0010] In some embodiments, the air supply channel is located above the partition, and the return air channel is located below the partition to ensure that the items inside the refrigerating chamber can be cooled. The air supply port is located above the air duct module, and the return air port is located below the air duct module to ensure that the items inside the freezing chamber can be cooled.

[0011] In some embodiments, a communication groove communicating the second communication port and the return air channel is formed on the inner container; wherein, the length of the communication groove matches the thickness of the partition to facilitate the communication between the second communication port and the return air channel.

[0012] In some embodiments, the horizontal freezer further includes: a control valve disposed in the air duct module and located at the first communication port for controlling the opening and closing of the first communication port, thereby further ensuring that the refrigerating chamber can be temperature-controlled independently of the freezing chamber.

[0013] In some embodiments, the first communication port and the air supply port are located in the same area of the air duct module to achieve rapid refrigeration of the refrigerating chamber.

[0014] In some embodiments, an air outlet is formed in the air supply channel, and the horizontal freezer further includes: a first air outlet adjusting member disposed on the partition member and located at the air outlet for adjusting the opening degree of the air outlet; a second air outlet adjusting member disposed in the air duct module and located at the air supply port for adjusting the opening degree of the air supply port to control the amount of cold air entering the refrigerating chamber and the freezing chamber.

[0015] In some embodiments, the horizontal freezer further includes: a first anti-blocking member disposed on the partition member and located above the return air channel; a second anti-blocking member disposed in the air duct module and located above the return air port to prevent the return air channel and the return air port from being blocked by objects.

[0016] In some embodiments, an installation groove is formed in the side wall of the inner container, and the air duct module includes: a housing embedded in the installation groove to form a first accommodation cavity and a second accommodation cavity communicating with the first accommodation cavity; a fan assembly disposed in the first accommodation cavity; wherein, an evaporator is disposed in the second accommodation cavity to facilitate the installation of the air duct module.

[0032] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0033] A horizontal freezer provided in this embodiment aims to at least solve the technical problem of unstable temperature in the refrigerating chamber to a certain extent.

[0034] Figure 1 It is a schematic structural diagram of a horizontal freezer in some embodiments; Figure 2 is Figure 1 The layout schematic diagram of the air duct module of the horizontal freezer in. Combining Figure 1 and Figure 2 , the horizontal freezer of the embodiment of the present application includes: an inner container 10, a partition 20, an air duct module 30, and an evaporator 40. The partition 20 is disposed in the inner container 10 to form a refrigerating chamber 101 and a freezing chamber 102. The partition 20 is provided with a supply air channel 201 and a return air channel 202 that communicate with the refrigerating chamber 101. The air duct module 30 is disposed in the freezing chamber 102 and has a supply air port 301 communicating with the freezing chamber 102, a return air port 302 communicating with the freezing chamber 102, a first communication port 303 communicating with the supply air channel 201, and a second communication port 304 communicating with the return air channel 202. The evaporator 40 is disposed in the freezing chamber 102 and is used for heat exchange with the air in the air duct module 30.

[0035] The partition 20 can be a middle partition or a foaming layer.

[0036] Since the partition member 20 is disposed inside the inner container 10 to form the refrigerating chamber 101 and the freezing chamber 102, the partition member 20 is provided with an air supply passage 201 and a return air passage 202 communicating with the refrigerating chamber 101. The air duct module 30 is disposed inside the freezing chamber 102. The air duct module 30 has an air supply port 301 communicating with the freezing chamber 102, a return air port 302 communicating with the freezing chamber 102, a first communication port 303 communicating with the air supply passage 201, and a second communication port 304 communicating with the return air passage 202. The evaporator 40 is disposed inside the freezing chamber 102 and is used for exchanging heat with the air inside the air duct module 30. Therefore, the air duct module 30 can send the air exchanged with the evaporator 40 into the refrigerating chamber 101 through the first communication port 303 and the air supply passage 201, and then send the hot air inside the refrigerating chamber 101 to the evaporator 40 through the return air passage 202 and the second communication port 304 to exchange heat with the evaporator 40, so as to maintain a constant low-temperature environment inside the refrigerating chamber 101, realize an independent path for the air circulation in the refrigerating chamber 101, ensure that the temperature control of the refrigerating chamber 101 can be independent of the freezing chamber 102, improve the accuracy and stability of the temperature control, and ensure the stable temperature of the refrigerating chamber 101. Moreover, since the refrigerating chamber 101 and the freezing chamber 102 are physically isolated by the partition member 20 and the air circulation in the refrigerating chamber 101 does not directly depend on the refrigeration effect of the freezing chamber 102, the direct contact opportunity between the wet air inside the refrigerating chamber 101 and the cold surface inside the freezing chamber 102 is reduced. At the same time, after the air inside the air duct module 30 exchanges heat with the evaporator 40, the temperature is precisely controlled, reducing the possibility of condensate water forming on the surface of the inner container 10, thereby effectively avoiding the problem of frosting on the inner container 10. The air duct module 30 can send the air exchanged with the evaporator 40 into the freezing chamber 102 through the air supply port 301, and then send the hot air inside the freezing chamber 102 to the evaporator 40 through the return air port 302 to exchange heat with the evaporator 40, so as to maintain a constant low-temperature environment inside the freezing chamber 102, realize an independent path for the air circulation in the freezing chamber 102, make the temperature control of the freezing chamber 102 and the temperature control of the refrigerating chamber 101 independent of each other, improve the accuracy and stability of the temperature control, and ensure the stable temperature of the freezing chamber 102.

[0037] Combined with Figure 2 , in some embodiments, since the evaporator 40 is disposed inside the freezing chamber 102, the evaporator 40 can absorb the heat of the surrounding air and convert it into cold air to work, which can ensure that the cold air directly acts on the freezing chamber 102, thereby improving the refrigeration efficiency, reducing the loss of cold air during the transmission process, and enabling the freezing chamber 102 to reach and maintain the set low-temperature state more quickly.

[0038] Combined with Figure 1, in some embodiments, to facilitate the arrangement of the air duct module 20, the air duct module 30 is arranged at an angle with the partition 20, so that the air duct module 20 can flexibly adapt to the spatial structure inside the inner container 10, which helps to maximize the utilization of the space inside the inner container 10, ensuring that both the refrigerating chamber 101 and the freezing chamber 102 can obtain sufficient volume, while not affecting the arrangement and performance of the air duct module 20.

[0039] In some embodiments, the included angle between the air duct module 30 and the partition 20 can be an acute angle, a right angle or an obtuse angle. When the air duct module 30 is perpendicular to the partition 20, the perpendicular relationship between the air duct module 30 and the partition 20 is not an absolute perpendicular in the geometric sense, and the angular relationship between the air duct module 30 and the partition 20 can be in the range of 90±3°.

[0040] Combined with Figure 1 and Figure 2 , in some embodiments, to facilitate the connection between the first communication port 303 and the air supply channel 201 and the connection between the second communication port 304 and the air return channel 202, the air duct module 30 is located on one side of the inner container 10 in the thickness direction, and the partition 20 is arranged along the thickness direction of the inner container 10. That is to say, the air duct module 30 is not arranged on one side of the inner container 10 in the width direction, which can enable the first communication port 303 to be directly connected to the air supply channel 201, and the second communication port 304 to be directly connected to the air return channel 202, without the need for additional air ducts or complex connecting parts to realize the functions of air supply and air return, reducing the material cost and the complexity of processing and installation. Moreover, the air duct module 30 does not occupy the width space inside the inner container 10, improving the space utilization rate of the inner container 10.

[0041] In some embodiments, the horizontal freezer includes a main body, and the main body includes a housing and an inner container disposed inside the housing. The main body is generally a cuboid. For the convenience of description, the height direction, width direction and thickness direction are respectively defined. Among them, in the use state of the horizontal freezer, the vertical direction is the height direction of the inner container 10, and the projection of the inner container 10 in the vertical direction is a rectangle. The direction where the long side of the inner container 10 is located is the width direction of the inner container 10, and the direction where the wide side of the inner container 10 is located is the thickness direction of the inner container 10. The main body is rotatably connected to the door body, generally connected to the opening of the main body. Specifically, it is connected to a side edge in the width direction, so that one end of the door body rotates along the thickness direction during the opening process of the door body.

[0042] Combined with Figure 1 and Figure 2, in some embodiments, to ensure that the items in the refrigerating chamber 101 can be cooled, the air supply channel 201 is located above the partition member 20, and the air return channel 202 is located below the partition member 20. After being cooled by the evaporator 40, the air forms cold air. The cold air enters the air supply channel 201 through the air duct module 30, and then enters the refrigerating chamber 101 from above the partition member 20, which helps to form natural convection, that is, the cold air sinks and the hot air rises, thereby accelerating the heat exchange process in the refrigerating chamber 101, improving the refrigeration effect, enabling the cold air to be directly and efficiently sent into the refrigerating chamber 101, reducing the resistance and heat exchange of the cold air during the transmission process, ensuring the refrigeration efficiency. The air that exchanges heat with the items in the refrigerating chamber 101 forms hot air. The hot air can pass through the air return channel 202 and smoothly return to the evaporator 40 through the air duct module 30 from below the partition member 20 for re-cooling, avoiding the retention and accumulation of cold air in the refrigerating chamber 101, ensuring the uniformity and stability of the temperature in the refrigerating chamber 101. At the same time, by utilizing the natural upward characteristic of the hot air, the hot air can naturally flow towards the air return channel 202, further improving the heat exchange efficiency.

[0043] Combined with Figure 1 and Figure 2 , in some embodiments, to ensure that the items in the freezing chamber 102 can be cooled, the air supply port 301 is located above the air duct module 30, and the air return port 302 is located below the air duct module 30. After being cooled by the evaporator 40, the air forms cold air. The cold air reaches the air supply port 301 through the air duct module 30, and then enters the freezing chamber 102 from above the air duct module 30, which helps to form natural convection, that is, the cold air sinks and the hot air rises, thereby accelerating the heat exchange process in the freezing chamber 102, improving the refrigeration effect, enabling the cold air to be directly and efficiently sent into the freezing chamber 102, reducing the resistance and heat exchange of the cold air during the transmission process, ensuring the refrigeration efficiency. The air that exchanges heat with the items in the freezing chamber 102 forms hot air. The hot air can pass through the air return port 302 and smoothly return to the evaporator 40 through the air duct module 30 from below the air duct module 30 for re-cooling, avoiding the retention and accumulation of cold air in the freezing chamber 102, ensuring the uniformity and stability of the temperature in the freezing chamber 102. At the same time, by utilizing the natural upward characteristic of the hot air, the hot air can naturally flow towards the air return port 302, further improving the heat exchange efficiency.

[0044] Combined with Figure 2 , in some embodiments, to facilitate the connection between the second communication port 304 and the air return channel 202, a connection groove 103 connecting the second communication port 304 and the air return channel 202 is formed on the inner container 10. The connection groove 103 serves as a direct connection channel, which can significantly reduce the obstruction and resistance of the air flow when entering the air return channel 202 from the second communication port 304, enabling the air flow to flow more smoothly and quickly.

[0045] In some embodiments, in order to prevent air leakage from the communication groove 103, the length of the communication groove 103 matches the thickness of the partition member 20. By sealing the opening of the communication groove 103 with the side wall of the partition member 20, the possibility of air leakage from the communication groove 103 can be reduced or eliminated, forming an effective sealing barrier, ensuring the directional flow of air, avoiding unnecessary energy loss and efficiency reduction, achieving the sealing of the communication groove 103, preventing air leakage, maintaining the air pressure stability inside the freezer compartment 102, and ensuring the efficient circulation of air along the designed path. At the same time, the partition member 20 can not only divide the inner container 10 into the refrigerating compartment 101 and the freezer compartment 102, but also close the opening of the communication groove 103, achieving dual functions with one component and reducing costs.

[0046] Combined with Figure 2 , in some embodiments, in order to further ensure that the refrigerating compartment 101 can be independently temperature-controlled from the freezer compartment 102, the horizontal freezer further includes: a control valve 50. The control valve 50 is disposed in the air duct module 30 and is located at the first communication port 303 for controlling the opening and closing of the first communication port 303.

[0047] In some embodiments, the control valve 50 can be used to open or close the first communication port 303 as needed, enabling the refrigerating compartment 101 and the freezer compartment 102 to maintain their respective required temperature environments independently of the temperature fluctuations of each other, achieving the simultaneous storage of foods with different temperature requirements. When the temperature in the refrigerating compartment 101 has reached the set value and is stable, the first communication port 303 can be closed through the control valve 50, causing all the air cooled by the evaporator 40 to enter the freezer compartment 102, achieving the rapid freezing of the items in the freezer compartment 102. Moreover, independent temperature control means that the refrigerating compartment 101 and the freezer compartment 102 can optimize their storage environments respectively. For the refrigerating compartment 101, maintaining appropriate temperature and humidity is crucial for keeping the freshness and taste of food. By adjusting the flow rate of the air cooled by the evaporator 40 entering the refrigerating compartment 101 through the control valve 50, the environmental parameters inside the refrigerating compartment 101 can be better controlled, improving the preservation effect. Users can freely adjust the temperatures of the refrigerating compartment 101 and the freezer compartment 102 according to actual needs without worrying about the mutual influence between the two, enhancing user satisfaction and usage experience.

[0048] In some embodiments, to achieve rapid refrigeration in the refrigerating chamber 101, the first communication port 303 and the air supply port 301 are located in the same area of the air duct module 30. That is to say, the heights of the first communication port 303 and the air supply port 301 on the air duct module 30 are similar. The air cooled by the evaporator 40 will enter the first communication port 303 and the air supply port 301 respectively, so that the temperature and flow rate of the cold air entering the first communication port 303 and the air supply port 301 are less different, which can help balance the cold quantity distribution of the two refrigerating chambers 101 and the freezing chamber 102, reduce the temperature fluctuation caused by too large a cold quantity difference, and ensure that the refrigerating chamber 101 can quickly and stably reach the required temperature.

[0049] Combined with Figure 1 , in some embodiments, to control the cold quantity entering the refrigerating chamber 101 and the freezing chamber 102, the air supply channel 201 is provided with an air outlet 203. The horizontal freezer further includes: a first air outlet adjusting member 60 and a second air outlet adjusting member 70. The first air outlet adjusting member 60 is disposed on the partition member 20 and is located at the air outlet 203 for adjusting the opening degree of the air outlet 203. The second air outlet adjusting member 70 is disposed on the air duct module 30 and is located at the air supply port 301 for adjusting the opening degree of the air supply port 301. Among them, the first air outlet adjusting member 60 and the second air outlet adjusting member 70 can be manual air supply paddles or automatic air dampers.

[0050] In some embodiments, the first air outlet adjusting member 60 can adjust the opening degree of the air outlet 203, thereby controlling the cold air flow rate passing through the air outlet 203. This enables the user or the control system to flexibly adjust the cold quantity entering the refrigerating chamber 101 according to the actual needs of the refrigerating chamber 101. When rapid refrigeration or maintaining a specific temperature is required, the supply of cold air can be increased or decreased accordingly. When the temperature of the refrigerating chamber 101 has reached the set value and is stable, the first air outlet adjusting member 60 can reduce the opening degree of the corresponding air outlet 203 to reduce the cold air supply, reduce unnecessary cold air waste, improve the overall energy efficiency, and thus save energy. At the same time, the first air outlet adjusting member 60 can adjust the air outlet direction of the air outlet 203 according to the indoor layout and the characteristics of the stored items to achieve uniform diffusion of cold air and avoid local overcooling or overheating phenomena, so that the cold air entering the refrigerating chamber 101 is evenly distributed, ensuring the stability and consistency of the internal temperature of the refrigerating chamber 101.

[0051] In some embodiments, the second air outlet adjusting member 70 can adjust the opening degree of the air outlet 301, thereby controlling the cold air flow rate passing through the air outlet 301. This enables the user or the control system to flexibly adjust the amount of cold air entering the freezer compartment 102 according to the actual needs of the freezer compartment 102. When rapid refrigeration is required or a specific temperature needs to be maintained, the supply amount of cold air can be increased or decreased accordingly. When the temperature in the freezer compartment 102 has reached the set value and is stable, the opening degree of the corresponding air outlet 301 can be reduced through the second air outlet adjusting member 70 to reduce the cold air supply, reducing unnecessary cold air waste, improving the overall energy efficiency, and thus saving energy. At the same time, the second air outlet adjusting member 70 can adjust the air outlet direction of the air outlet 301 according to the indoor layout and the characteristics of the stored items to achieve uniform diffusion of cold air, avoiding the occurrence of local overcooling or overheating phenomena, enabling the uniform distribution of the cold air entering the freezer compartment 102, and ensuring the stability and consistency of the internal temperature of the freezer compartment 102.

[0052] Since the return air passage 202 is located below the partition member 20 and the return air outlet 302 is located below the air duct module 30, when placing items into the refrigerating compartment 101 and the freezer compartment 102, the items may block the return air passage 202 and the return air outlet 302, affecting the return air. In some embodiments, to prevent the return air passage 202 and the return air outlet 302 from being blocked by items, the horizontal freezer further includes: a first anti-blocking member and a second anti-blocking member. The first anti-blocking member is provided on the partition member 20 and is located above the return air passage 202. The second anti-blocking member is provided on the air duct module 30 and is located above the return air outlet 302. Among them, the first anti-blocking member and the second anti-blocking member can be ribs.

[0053] In some embodiments, when the user or operator places or removes items, if the items accidentally approach or contact the return air passage 202, the first anti-blocking member will act as a barrier to prevent the items from directly falling into or blocking the return air passage 202, reducing the risk of the return air passage 202 being accidentally blocked by the items stored in the freezer, ensuring the smooth circulation of the cold air in the refrigerating compartment 101, ensuring uniform temperature in the refrigerating compartment 101, ensuring the refrigeration efficiency and performance of the horizontal freezer, ensuring the refrigeration effect, and maintaining the normal operation and high efficiency of the horizontal freezer. Moreover, if the return air passage 202 is blocked and the cold air circulation is obstructed, the horizontal freezer may require a longer time or higher power to reach the set temperature, which will increase the burden on key components such as the evaporator 40 and shorten its service life. By reducing the risk of the return air passage 202 being blocked through the first anti-blocking member, the internal refrigeration components (such as the evaporator 40, etc.) of the freezer can be protected, and the service life of the overall equipment can be extended.

[0054] In some embodiments, when a user or operator places or removes an item, if the item accidentally approaches or touches the air return opening 302, the second anti-blocking member will act as a barrier to prevent the item from directly falling into or blocking the air return opening 302, reducing the risk of the air return opening 302 being accidentally blocked by items stored in the freezer, ensuring smooth circulation of cold air in the freezer compartment 102, ensuring uniform temperature in the freezer compartment 102, ensuring the refrigeration efficiency and performance of the horizontal freezer, ensuring the refrigeration effect, and maintaining the normal operation and high efficiency of the horizontal freezer. Moreover, if the air return opening 302 is blocked and the cold air circulation is hindered, the horizontal freezer may require a longer time or higher power to reach the set temperature, which will increase the burden on key components such as the evaporator 40 and shorten its service life. By reducing the risk of the air return opening 302 being blocked by the second anti-blocking member, the internal refrigeration components of the freezer (such as the evaporator 40, etc.) can be protected, and the service life of the overall equipment can be extended.

[0055] Combined with Figure 1 and Figure 2 , in some embodiments, to facilitate the installation of the air duct module 30, an installation groove 104 is formed in the side wall of the inner container 10. The air duct module 30 includes: a housing 305 and a fan assembly 306. The housing 305 is embedded in the installation groove 104 to form a first accommodation cavity 307 and a second accommodation cavity 308 communicating with the first accommodation cavity 307. The fan assembly 306 is disposed in the first accommodation cavity 307. Among them, an evaporator 40 is disposed in the second accommodation cavity 308. Among them, the first accommodation cavity 307 communicates with the air supply opening 301 and the first communication port 303, and the second accommodation cavity 308 communicates with the air return opening 302 and the second communication port 304.

[0056] In some embodiments, by accommodating the housing 305 through the installation groove 104, the installation groove 104 can provide a clear positioning and guidance for the housing 305, enabling the position of the housing 305 to be quickly and accurately found and fixed during installation, reducing the adjustment and calibration work during the installation process, improving the installation efficiency. Since the housing 305 is directly embedded in the installation groove 104, the installation steps are simplified. The installer only needs to align the housing 305 with the installation groove 104 and then firmly install it in place through appropriate fixing methods (such as screws, buckles, etc.), reducing the requirements for the installer's skill level and also reducing problems caused by improper installation. The groove wall of the installation groove 104 can provide stable support and protection for the housing 305, reducing potential damage during the installation process. At the same time, the tight fit between the groove wall of the installation groove 104 and the housing 305 can ensure that the housing 10 remains stable after installation, is not easily loosened or displaced, and ensures the stability of the installation of the housing 10.

[0057] In some embodiments, the inner container 10 has a first side wall, a second side wall, a third side wall, and a fourth side wall that are sequentially connected end to end. The first side wall and the third side wall are both parallel to the partition member 20, and the second side wall and the fourth side wall are both arranged at an angle to the partition member 20. Among them, the installation groove 104 can be opened on the second side wall or the fourth side wall, and the installation groove 104 is located in the freezer compartment 102.

[0058] In some embodiments, the included angle between the second side wall and the fourth side wall and the partition member 20 can be set at 45° to 135°. In this embodiment, only the included angle between the second side wall and the fourth side wall and the partition member 20 is 90°, that is, the second side wall and the fourth side wall are perpendicular to the partition member 20 as an example for illustration, and it should not be construed as a limitation to this application.

[0059] In some embodiments, by accommodating the housing 305 through the installation groove 104, the additional space occupied by the housing 305 inside the freezer compartment 102 can be reduced, thereby maximizing the effective volume of the freezer compartment 102, enabling users to store more food, improving the storage efficiency, and enhancing the user experience.

[0060] In some embodiments, when refrigeration is to be performed, the fan assembly 306 and the evaporator 40 are started, so that air enters the second accommodation chamber 308 from the air return port 302 and the second communication port 304 to exchange heat with the evaporator 40. The air after heat exchange enters the first accommodation chamber 307, and then enters the freezer compartment 102 through the air supply port 301, and enters the refrigerating chamber 101 through the first communication port 303 and the air supply channel 201, making the air flow smoothly, and the air can flow efficiently along the set path, thereby improving the refrigeration efficiency.

[0061] In some embodiments, by arranging the fan assembly 306 in the first accommodation chamber 307, it is ensured that the air can be effectively and centrally accelerated into the second accommodation chamber 308, making the heat exchange process more efficient. The air after heat exchange can smoothly enter the first accommodation chamber 307 and then be discharged through the air supply port 301 and the first communication port 303, which can avoid the disorder and vortex of the air flow, ensure the stability of the air flow, enable the air to flow efficiently along the set path, and thus improve the overall efficiency of the system. Moreover, the first accommodation chamber 307 provides a relatively closed and stable operating environment for the fan assembly 306, reducing the performance fluctuations caused by external interference. At the same time, the second accommodation chamber 308 can prevent the air flow from directly impacting the evaporator 40 or other components, further reducing the generation of noise and vibration.

[0062] In some embodiments, along the height direction of the inner container 10, the blower assembly 306 and the evaporator 40 are arranged in sequence from top to bottom, such that air enters the second accommodation chamber 308 from the air return port 302 and the second communication port 304 to exchange heat with the evaporator 40. The air after heat exchange enters the first accommodation chamber 307, and then enters the freezer compartment 102 through the air supply port 301, and enters the refrigerator compartment 101 through the first communication port 303 and the air supply channel 201, such that the air flows smoothly, and the air can flow efficiently along the set path, thereby improving the refrigeration efficiency.

[0063] In some embodiments, the thickness of the housing 305 matches the depth of the installation groove 104, such that the housing 305 is flush with the inner surface of the inner container 10, ensuring that the housing 305 remains flush with the inner surface of the inner container 10. While ensuring aesthetics, it also avoids the housing 305 occupying additional space inside the freezer compartment 102, thereby maximizing the effective volume of the freezer compartment 102, enabling users to store more food, improving the storage efficiency, and enhancing the user experience.
