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, most horizontal dual-temperature freezers on the market commonly use the method of winding pipes to control the temperatures of the freezer compartment and the refrigerating 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 refrigerating compartment is indirectly controlled by adjusting the number of winding pipes and the winding pipe spacing.

[0003] However, in the prior art, since the refrigerating compartment and the freezer compartment share a set of winding pipe systems, the temperature control of the refrigerating compartment is directly restricted by the refrigeration demand of the freezer compartment. When the freezer compartment needs to cool down quickly, the refrigerating compartment will also be greatly affected, resulting in large temperature fluctuations in the refrigerating compartment, unstable temperature in the refrigerating compartment, affecting the freshness preservation effect of the stored items, and thus triggering 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 refrigerating 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; an air duct module disposed inside the inner container to form a refrigerating compartment and a freezer compartment, and air ducts communicating with the refrigerating compartment and the freezer compartment are provided in the air duct module; an evaporator disposed inside the inner container and used for heat exchange with the air in the air duct module; and a refrigeration component communicating with the evaporator and wound around the freezer compartment.

[0007] Since the air duct module is disposed inside the inner container to form a refrigerating chamber and a freezing chamber, and an air duct communicating with the refrigerating chamber and the freezing chamber is provided in the air duct module, and the evaporator is disposed inside the inner container and is used for heat exchange with the air in the air duct module, therefore, the air duct module can send the air heat-exchanged with the evaporator into the refrigerating chamber and the freezing chamber respectively through the air duct, and then send the hot air in the refrigerating chamber and the freezing chamber to the evaporator through the air duct for heat exchange to maintain a constant low-temperature environment in the refrigerating chamber and the freezing chamber. The refrigerating chamber and the freezing chamber are two independent compartments, realizing an independent path for the air circulation in the refrigerating chamber and an independent path for the air circulation in the freezing chamber, ensuring that the temperature of the refrigerating chamber can be controlled independently of the freezing chamber, improving the accuracy and stability of temperature control, and ensuring the stability of the temperature in the refrigerating chamber. Since the refrigerating chamber and the freezing chamber are physically isolated through the air duct module, the temperature control of the freezing chamber and the temperature control of the refrigerating chamber are independent of each other, improving the accuracy and stability of temperature control and also ensuring the stability of the temperature in the freezing chamber. And the air circulation in the refrigerating chamber does not directly depend on the refrigeration effect of the freezing chamber. Therefore, the direct contact opportunity between the wet air in the refrigerating chamber and the cold surface in the freezing chamber is reduced. At the same time, the temperature of the air in the air duct module is precisely controlled after heat exchange with the evaporator, reducing the possibility of condensate formation on the surface of the inner container, thereby effectively avoiding the problem of frosting of the inner container. The temperature control of the freezing chamber and the temperature control of the refrigerating chamber are independent of each other, improving the accuracy and stability of temperature control and ensuring the stability of the temperature in the freezing chamber. Since the refrigerating component is communicated with the evaporator and is wound around the freezing chamber, when the air duct module sends the air heat-exchanged with the evaporator into the freezing chamber through the air duct respectively, the refrigerating component can simultaneously refrigerate the freezing chamber, making the contact between the refrigerating component and the freezing chamber sufficient, increasing the heat exchange area. The refrigerant in the evaporator flows in the refrigerating component, continuously absorbing the heat of the air in the freezing chamber, and cooperating with the cold air entering the freezing chamber, can quickly cool down the freezing chamber and improve the user experience.

[0008] In some embodiments, the inner container has a bottom surface and a stepped surface higher than the bottom surface. The air duct module is disposed on the bottom surface, and the air duct module and the stepped surface form a refrigerating chamber, and the air duct module and the bottom surface form a freezing chamber, so as to facilitate the arrangement of the air duct module.

[0009] In some embodiments, at least part of the refrigerating component is disposed below the stepped surface to ensure the refrigeration effect of the freezing chamber.

[0010] In some embodiments, the air duct module is provided with a first air supply outlet, a first air return outlet, a second air supply outlet and a second air return outlet that communicate with the air duct. The first air supply outlet and the first air return outlet are both in communication with the refrigerating chamber, and the second air supply outlet and the second air return outlet are both in communication with the freezing chamber. Among them, the first air supply outlet and the second air supply outlet are both located above the air duct module, and the first air return outlet and the second air return outlet are both located below the air duct module to cool the refrigerating chamber and the freezing chamber.

[0011] In some embodiments, the air duct module is provided with a third air supply outlet that communicates with the air duct and the freezing chamber. The third air supply outlet is located between the second air supply outlet and the second air return outlet to ensure the refrigeration effect of the freezing chamber.

[0012] In some embodiments, along the height direction of the inner container, the third air supply outlet is located at 3 / 5 to 4 / 5 of the inner container to further ensure the refrigeration effect of the freezing chamber.

[0013] In some embodiments, the horizontal freezer further includes: a first air outlet adjusting member disposed on the air duct module and located at the first air supply outlet for adjusting the opening degree of the first air supply outlet; a second air outlet adjusting member disposed on the air duct module and located at the second air supply outlet for adjusting the opening degree of the second air supply outlet to achieve control of the cold quantity entering the refrigerating chamber and the freezing chamber.

[0014] In some embodiments, the refrigerating chamber is provided with a third air return outlet that is angled with the first air supply outlet. The horizontal freezer further includes: a connecting member that is inclined and communicates with the third air return outlet and the first air return outlet to guide the air that has exchanged heat with the items in the refrigerating chamber 101 to the evaporator.

[0015] In some embodiments, the third air return outlet is located on one side in the thickness direction of the inner container, and the second air supply outlet is arranged along the thickness direction of the inner container to facilitate the arrangement of the evaporator.

[0016] In some embodiments, the horizontal freezer further includes: a first anti-blocking member disposed on the air duct module and located outside the air duct. The first anti-blocking member is located above the third air return outlet; a second anti-blocking member disposed on the air duct module and located outside the air duct. The second anti-blocking member is located above the second air return outlet to prevent the second air return outlet and the third air return outlet from being blocked by items.

[0017] In some embodiments, the air duct assembly includes: a housing having a first chamber and disposed in the inner container, the housing and the inner container forming a second chamber communicating with the first chamber; a fan assembly disposed in the first chamber; wherein, the evaporator is disposed in the second chamber to further improve the refrigeration efficiency.

[0037] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0038] 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.

[0039] Figure 1 is a structural schematic diagram of a horizontal freezer for some embodiments; Figure 2 is Figure 1 a layout schematic diagram of the refrigerating chamber of the horizontal freezer in Figure 3 is Figure 1Top view of the connecting member of the horizontal freezer. In combination with Figure 1 , Figure 2 and Figure 3 , the horizontal freezer of the embodiment of the present application includes: an inner container 10, an air duct module 20, an evaporator 30 and a refrigerating member 40. The air duct module 20 is arranged in the inner container 10 to form a refrigerating chamber 101 and a freezing chamber 102. An air duct 201 communicating with the refrigerating chamber 101 and the freezing chamber 102 is opened in the air duct module 20. The evaporator 30 is arranged in the inner container 10 and is used for exchanging heat with the air in the air duct module 20. The refrigerating member 40 is communicated with the evaporator 30 and is wound around the freezing chamber 102.

[0040] The refrigerating member 40 can be a refrigerating coil or a patch evaporator, etc.

[0041] Since the air duct module 20 is disposed inside the inner container 10 to form the refrigerating chamber 101 and the freezing chamber 102, and the air duct 201 communicating with the refrigerating chamber 101 and the freezing chamber 102 is provided in the air duct module 20, and the evaporator 30 is disposed inside the inner container 10 and is used for heat exchange with the air in the air duct module 20, therefore, the air duct module 20 can send the air after heat exchange with the evaporator 30 into the refrigerating chamber 101 and the freezing chamber 102 respectively through the air duct 201, and then send the hot air in the refrigerating chamber 101 and the freezing chamber 102 to the evaporator 30 through the air duct 201 for heat exchange with the evaporator 30 to maintain a constant low temperature environment in the refrigerating chamber 101 and the refrigerating chamber 101. The refrigerating chamber 101 and the freezing chamber 102 are two independent compartments, realizing an independent path for the air circulation in the refrigerating chamber 101 and an independent path for the air circulation in the freezing chamber 102, ensuring that the refrigerating chamber 101 can be temperature-controlled independently of the freezing chamber 102, improving the accuracy and stability of temperature control, and ensuring the stable temperature of the refrigerating chamber 101. Since the refrigerating chamber 101 and the freezing chamber 102 are physically isolated through the air duct module 20, the temperature control of the freezing chamber 102 and the temperature control of the refrigerating chamber 101 are independent of each other, improving the accuracy and stability of temperature control, and also ensuring the stable temperature of the freezing chamber 102. And the air circulation in the refrigerating chamber 101 does not directly depend on the refrigeration effect of the freezing chamber 102. Therefore, the direct contact opportunity between the wet air in the refrigerating chamber 101 and the cold surface in the freezing chamber 102 is reduced. At the same time, the temperature of the air in the air duct module 20 is precisely controlled after heat exchange with the evaporator 30, reducing the possibility of condensate water forming on the surface of the inner container 10, thus effectively avoiding the problem of frosting of the inner container 10. The temperature control of the freezing chamber 102 and the temperature control of the refrigerating chamber 101 are independent of each other, improving the accuracy and stability of temperature control, and ensuring the stable temperature of the freezing chamber 102. Since the refrigerating component 40 is communicated with the evaporator 30 and is wound around the freezing chamber 102, therefore, when the air duct module 20 sends the air after heat exchange with the evaporator 30 into the freezing chamber 102 through the air duct 201 respectively, the refrigerating component 40 can refrigerate the freezing chamber 102 at the same time, making the refrigerating component 40 in full contact with the freezing chamber 102, increasing the heat exchange area. The refrigerant in the evaporator 30 flows in the refrigerating component 40, continuously absorbing the heat of the air in the freezing chamber 102, and cooperating with the cold air entering the freezing chamber 102, can quickly cool down the freezing chamber 102 and improve the user experience.

[0042] In some embodiments, a foaming layer may be provided outside the air duct module 20 for heat insulation, which can effectively isolate the heat exchange between the refrigerating chamber 101 and the freezing chamber 102 to ensure the temperature stability in the refrigerating chamber 101 and the freezing chamber 102.

[0043] In some embodiments, the air duct module 20 can not only serve as a partition to divide the inner container 10 into a refrigerating chamber 101 and a freezing chamber 102, but also guide the air to circulate in the refrigerating chamber 101 and the freezing chamber 102, achieving dual functions with one component and reducing costs. Moreover, the need for additional installation of a partition and an air duct 201 can be avoided, thus saving valuable internal space, maximizing the effective volume of the refrigerating chamber 101 and the freezing chamber 102, enabling users to store more food, improving the storage efficiency, and enhancing the user experience.

[0044] Combined with Figure 1 and Figure 2 , in some embodiments, for the convenience of arranging the air duct module 20, the inner container 10 has a bottom surface 103 and a stepped surface 104 higher than the bottom surface 103. The air duct module 20 is disposed on the bottom surface 103. The air duct module 20 and the stepped surface 104 form the refrigerating chamber 101, and the air duct module 20 and the bottom surface 103 form the freezing chamber 102. The stepped surface 104 can reasonably divide the internal space of the inner container 10. The air duct module 20 can be closely arranged against the bottom surface 103, and the stepped surface 104 naturally forms the boundary of the refrigerating chamber 101 with the air duct module 20 without additional partitions, thus saving space. When the user looks down from top to bottom, the steps cannot be directly seen, which maintains the cleanliness and beauty of the internal space of the inner container 10 and improves the overall design quality. Moreover, since the steps formed by the height difference between the stepped surface 104 and the bottom surface 103 can be hidden by the air duct module 20, the user will not be disturbed by the steps when accessing food, and can more conveniently pick up and place items.

[0045] Figure 4 For Figure 3 the A - A cross-sectional view of the horizontal freezer. Combined with Figure 1 , Figure 2 and Figure 4 , in some embodiments, for the convenience of installing the compressor 50, the horizontal freezer further includes: a compressor 50. The compressor 50 is disposed below the stepped surface 104. The height difference between the stepped surface 104 and the bottom surface 103 can serve as the installation space for the compressor 50, enabling the efficient utilization of the internal space of the horizontal freezer and avoiding occupying additional space by separately setting an installation area for the compressor. Moreover, placing the compressor 50 below the stepped surface 104 can make the overall structure of the horizontal freezer more compact, reduce the external dimensions of the horizontal freezer, and make it more suitable for the space limitations of modern kitchens or home environments.

[0046] Since items will accumulate in the freezing chamber 102, the cold air entering the freezing chamber 102 through the air duct 201 cannot reach the bottom area of the freezing chamber 102 well from the top area of the freezing chamber 102, resulting in a large temperature difference between the top area and the bottom area of the freezing chamber 102 and affecting the refrigeration effect of the freezing chamber 102. Combined withFigure 1 and Figure 2 , in some embodiments, to ensure the refrigeration effect of the freezer compartment 102, the refrigerating member 40 is at least partially disposed below the stepped surface 104. When the cold air after exchanging heat with the evaporator 30 enters the top region of the freezer compartment 102, the refrigerating member 40 can cool the bottom region of the freezer compartment 102. By directly cooling the bottom region of the freezer compartment 102 with the refrigerating member 40, the refrigerating member 40 can effectively reduce the temperature of the bottom region of the freezer, reduce the temperature difference between the top region and the bottom region of the freezer compartment 102, make the temperature distribution in the freezer compartment 102 uniform, and ensure the stable temperature of the freezer compartment 102. Moreover, when cooling the bottom region of the freezer compartment 102 through the refrigerating member 40, the cold air after exchanging heat with the evaporator 30 simultaneously enters the top region of the freezer compartment 102. Under the combined action of the two, the refrigeration time of the freezer compartment 102 can be shortened and the refrigeration efficiency can be improved. At the same time, since the cold air after exchanging heat with the evaporator 30 will enter the top region of the freezer compartment 102, the refrigerating member 40 does not need to be wound around the entire freezer compartment 102, which can reduce costs and facilitate the arrangement of the refrigerating member 40.

[0047] Combined with Figure 1 and Figure 2 , in some embodiments, to cool the refrigerating compartment 101 and the freezer compartment 102, the air duct module 20 is provided with a first air supply port 202, a first air return port 203, a second air supply port 204 and a second air return port 205 that communicate with the air duct 201. The first air supply port 202 and the first air return port 203 both communicate with the refrigerating compartment 101, and the second air supply port 204 and the second air return port 205 both communicate with the freezer compartment 102. Among them, the first air supply port 202 and the second air supply port 204 are both located above the air duct module 20, and the first air return port 203 and the second air return port 205 are both located below the air duct module 20.

[0048] In some embodiments, to ensure that the items in the refrigerating chamber 101 can be cooled, the first air supply outlet 202 is located above the air duct module 20, and the first air return outlet 203 is located below the air duct module 20. After being cooled by the evaporator 30, the air forms cold air. The cold air enters the air inlet passage 201 through the air duct module 30, and then enters the refrigerating chamber 101 from above the air duct module 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 has exchanged heat with the items in the refrigerating chamber 101 forms hot air. The hot air can pass through the first air return outlet 203 and smoothly return to the evaporator 30 through the air duct module 30 from below the air duct module 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 rising characteristic of the hot air, the hot air can naturally flow towards the first air return outlet 203, further improving the heat exchange efficiency.

[0049] Combined with Figure 1 and Figure 2 , in some embodiments, to ensure that the items in the freezing chamber 102 can be cooled, the second air supply outlet 204 is located above the air duct module 30, and the second air return outlet 205 is located below the air duct module 30. After being cooled by the evaporator 30, the air forms cold air. The cold air reaches the second air supply outlet 204 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 has exchanged heat with the items in the freezing chamber 102 forms hot air. The hot air can pass through the second air return outlet 205 and smoothly return to the evaporator 30 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 rising characteristic of the hot air, the hot air can naturally flow towards the second air return outlet 205, further improving the heat exchange efficiency.

[0050] Combined with Figure 1 and Figure 2, in some embodiments, the first air supply outlet 202 and the first air return outlet 203 are located on the same side of the air duct module 20, the second air supply outlet 204 and the second air return outlet 205 are located on the same side of the air duct module 20, and the first air supply outlet 202 and the second air supply outlet 204 are respectively located on opposite sides of the air duct module 20, realizing an independent path for the air circulation in the refrigerating chamber 101 and an independent path for the air circulation in the freezing chamber 102, ensuring that the temperature of the refrigerating chamber 101 can be controlled independently of the freezing chamber 102, improving the accuracy and stability of temperature control, and also ensuring the stable temperature of the refrigerating chamber 101.

[0051] Since items will accumulate in the freezing chamber 102, the cold air entering the freezing chamber 102 from the air duct 201 cannot reach the middle area of the freezing chamber 102 well, resulting in a large temperature difference between the top area and the middle area of the freezing chamber 102, which affects the refrigeration effect of the freezing chamber 102. Figure 5 For Figure 3 The B-B cross-sectional view of the medium horizontal freezer. Combining Figure 1 , Figure 2 , Figure 3 and Figure 5 , in some embodiments, in order to ensure the refrigeration effect of the freezing chamber 102, the air duct module 20 is provided with a third air supply outlet 206. The third air supply outlet 206 is communicated with the air duct 201 and the freezing chamber 102. The third air supply outlet 206 is located between the second air supply outlet 204 and the second air return outlet 205. Under the action of the air duct module 20, the air after exchanging heat with the evaporator 30 can directly send the cold air into the middle area of the freezing chamber 102 through the third air outlet 206, which can quickly reduce the temperature of the middle area of the freezing chamber 102 to reduce the temperature difference between the top area and the middle area of the freezing chamber 102. Moreover, after the cold air enters the freezing chamber 102 from the third air supply outlet 206, it will mix with the cold air sent into the freezing chamber 102 by the second air supply outlet 204 and sink, so as to form a more uniform temperature distribution in the whole freezing chamber 102, reduce the temperature difference between the top area and the middle area in the freezing chamber 102, improve the refrigeration uniformity. At the same time, the coordinated action of the second air supply outlet 204 and the third air supply outlet 206 can make the cold air reduce the temperature in the freezing chamber 102 faster, so as to shorten the overall cooling time and improve the refrigeration efficiency.

[0052] In some embodiments, to further ensure the refrigeration effect of the freezer compartment 102, along the height direction of the inner liner 10, the third air outlet 206 is located at 3 / 5 to 4 / 5 of the inner liner 10. The air after heat exchange with the evaporator 30, under the action of the air duct module 20, can directly send cold air into the middle area of the freezer compartment 102 through the third air outlet 206, which can quickly reduce the temperature of the middle area of the freezer compartment 102, so as to reduce the temperature difference between the top area and the middle area of the freezer compartment 102. Moreover, after the cold air enters the freezer compartment 102 from the third air outlet 206, it will mix with the cold air sent into the freezer compartment 102 by the second air outlet 204 and sink, thereby forming a more uniform temperature distribution in the entire freezer compartment 102, reducing the temperature difference between the top area and the middle area in the freezer compartment 102, improving the refrigeration uniformity. At the same time, the cooperation of the second air outlet 204 and the third air outlet 206 can enable the cold air to more quickly reduce the temperature in the freezer compartment 102, thereby shortening the overall cooling time and improving the refrigeration efficiency.

[0053] Combined with Figure 1 and Figure 2 , in some embodiments, to control the cold quantity entering the refrigerating compartment 101 and the freezer compartment 102, the horizontal freezer also includes: a first air outlet adjusting member 60 and a second air outlet adjusting member 70. The first air outlet adjusting member 60 is arranged in the air duct module 20 and is located at the first air outlet 202 for adjusting the opening degree of the first air outlet 202. The second air outlet adjusting member 70 is arranged in the air duct module 20 and is located at the second air outlet 204 for adjusting the opening degree of the second air outlet 204. Among them, the first air outlet adjusting member 60 and the second air outlet adjusting member 70 can be manually adjustable air supply paddles or automatically adjustable air doors. Among them, the first air outlet adjusting member 60 and the second air outlet adjusting member 70 can be manually adjustable air supply paddles or automatically adjustable air doors.

[0054] In some embodiments, the first air vent adjusting member 60 can adjust the opening degree of the first air supply vent 202, thereby controlling the cold air flow rate passing through the first air supply vent 202. This enables the user or the control system to flexibly adjust the amount of cold air entering the refrigerating chamber 101 according to the actual needs of the refrigerating chamber 101. When rapid refrigeration is required or a specific temperature needs to be maintained, 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 opening degree of the corresponding first air supply vent 202 can be reduced through the first air vent adjusting member 60 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 first air vent adjusting member 60 can adjust the air outlet direction of the first air supply vent 202 according to the indoor layout and the characteristics of the stored items to achieve uniform diffusion of cold air, avoiding local overcooling or overheating, and enabling uniform distribution of the cold air entering the refrigerating chamber 101, ensuring the stability and consistency of the internal temperature of the refrigerating chamber 101.

[0055] In some embodiments, the second air vent adjusting member 70 can adjust the opening degree of the second air supply vent 204, thereby controlling the cold air flow rate passing through the second air supply vent 204. This enables the user or the control system to flexibly adjust the amount of cold air entering the freezing chamber 102 according to the actual needs of the freezing chamber 102. When rapid refrigeration is required or a specific temperature needs to be maintained, the supply of cold air can be increased or decreased accordingly. When the temperature of the freezing chamber 102 has reached the set value and is stable, the opening degree of the corresponding second air supply vent 204 can be reduced through the second air vent 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 vent adjusting member 70 can adjust the air outlet direction of the second air supply vent 204 according to the indoor layout and the characteristics of the stored items to achieve uniform diffusion of cold air, avoiding local overcooling or overheating, and enabling uniform distribution of the cold air entering the freezing chamber 102, ensuring the stability and consistency of the internal temperature of the freezing chamber 102.

[0056] Combined with Figure 2 and Figure 4 In some embodiments, in order to guide the air that has exchanged heat with the items in the refrigerating chamber 101 to the evaporator 30, the refrigerating chamber 101 is provided with a third air return vent 105 that is arranged at an angle with the first air supply vent 202. The horizontal freezer further includes: a connecting member 80. The connecting member 80 is inclined and communicates with the third air return vent 105 and the first air return vent 203.

[0057] In some embodiments, due to the presence of the stepped surface 104, the bottom of the refrigerating chamber 101 is higher than the bottom of the freezing chamber 102. For the refrigeration effect, the area of the evaporator 30 is relatively large, resulting in a part of the evaporator 30 being located below the bottom of the refrigerating chamber 101. The third air return opening 105 is opened at the bottom of the refrigerating chamber 101. The connecting member 80 is inclined and communicates with the third air return opening 105 and the first air return opening 203, so as to guide the air that has exchanged heat with the items in the refrigerating chamber 101 to the first air return opening 203 through the connecting member 80. Under the action of the air duct module 20, the air that has exchanged heat with the items in the refrigerating chamber 101 can reach the bottom of the evaporator 30, so that the air that has exchanged heat with the items in the refrigerating chamber 101 can fully exchange heat with the evaporator 30, improving the heat exchange efficiency and ensuring the heat exchange effect.

[0058] In some embodiments, the included angle between the first air supply opening 202 and the third air return opening 105 can be an acute angle, a right angle or an obtuse angle. When the first air supply opening 202 is perpendicular to the third air return opening 105, the perpendicular relationship between the first air supply opening 202 and the third air return opening 105 is not an absolute perpendicular in the geometric sense. The angular relationship between the first air supply opening 202 and the third air return opening 105 can be in the range of 90±3°.

[0059] In some embodiments, for the convenience of arranging the evaporator 30, the third air return opening 105 is located on one side in the thickness direction of the inner container 10. The second air supply opening 204 is arranged along the thickness direction of the inner container 10. The third air return opening 105 does not need to occupy the complete area directly adjacent to the evaporator 30, which can provide more installation space for the evaporator 30 to facilitate the installation of the evaporator 30. Moreover, it can make the air supply and air return in the refrigerating chamber 101 stagger in the vertical direction, reducing the mutual interference between airflows to form a smooth air flow path and improving the efficiency and uniformity of air flow.

[0060] 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.

[0061] Since the second air return opening 205 is located below the freezer compartment 102 and the third air return opening 105 is located below the refrigerating compartment 101, when items are placed into the refrigerating compartment 101 and the freezer compartment 102, the items may block the second air return opening 205 and the third air return opening 105, affecting the air return. In some embodiments, to prevent the second air return opening 205 and the third air return opening 105 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 disposed in the air duct module 20 and outside the air duct 201, and the first anti-blocking member is located above the third air return opening 105. The second anti-blocking member is disposed in the air duct module 20 and outside the air duct 201, and the second anti-blocking member is located above the second air return opening 205. Wherein, the first anti-blocking member and the second anti-blocking member may be ribbed bars.

[0062] In some embodiments, when a user or an operator places or removes items, if an item accidentally approaches or contacts the third air return opening 105, the first anti-blocking member will act as a barrier to prevent the item from directly falling into or blocking the third air return opening 105, reducing the risk that the third air return opening 105 is accidentally blocked by items stored in the freezer, ensuring smooth air circulation 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 third air return opening 105 is not blocked and the air circulation is blocked, 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 30 and shorten its service life. By reducing the risk of the third air return opening 105 being blocked by the first anti-blocking member, the refrigeration components inside the freezer (such as the evaporator 30, etc.) can be protected, and the service life of the overall equipment can be extended.

[0063] In some embodiments, when a user or an operator places or removes items, if an item accidentally approaches or contacts the second air return opening 205, the second anti-blocking member will act as a barrier to prevent the item from directly falling into or blocking the second air return opening 205, reducing the risk that the second air return opening 205 is accidentally blocked by items stored in the freezer, ensuring smooth air circulation 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 second air return opening 205 is not blocked and the air circulation is blocked, 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 30 and shorten its service life. By reducing the risk of the second air return opening 205 being blocked by the second anti-blocking member, the refrigeration components inside the freezer (such as the evaporator 30, etc.) can be protected, and the service life of the overall equipment can be extended.

[0064] Combined with Figure 1 and Figure 5, in some embodiments, to further improve the refrigeration efficiency, the air duct 201 assembly includes: a housing 207 and a fan assembly 208. The housing 207 has a first chamber 209 and is disposed in the inner container 10, and a second chamber 210 communicating with the first chamber 209 is formed between the housing and the inner container 10. The fan assembly 208 is disposed in the first chamber 209. Among them, the evaporator 30 is disposed in the second chamber 210.

[0065] In some embodiments, when refrigeration is to be performed, the fan assembly 208 and the evaporator 30 are started, so that air enters the second chamber 210 from the first air return opening 203 and the second air return opening 205 to exchange heat with the evaporator 30. The air after heat exchange enters the first chamber 209, and then enters the freezer 102 through the second air supply opening 204 and enters the refrigerator compartment 101 through the first air supply opening 202, making the air flow smoothly. The air can flow efficiently along the set path, thereby improving the refrigeration efficiency.

[0066] In some embodiments, by disposing the fan assembly 208 in the first chamber 209, it is ensured that the air can be effectively and centrally accelerated into the second chamber 210, making the heat exchange process more efficient. The air after heat exchange can smoothly enter the first chamber 209 and then be discharged from the first air supply opening 202 and the second air supply opening 204, which can avoid the disorder and vortex of the air flow, ensure the stability of the air flow, make the air flow efficiently along the set path, and thus improve the overall efficiency of the system. Moreover, the first chamber 209 provides a relatively closed and stable operating environment for the fan assembly 208, reducing the performance fluctuations caused by external interference. At the same time, the second chamber 210 can prevent the air flow from directly impacting the evaporator 30 or other components, further reducing the generation of noise and vibration.

[0067] In some embodiments, along the height direction of the inner container 10, the fan assembly 208 and the evaporator 30 are arranged in sequence from top to bottom, so that air enters the second chamber 210 from the first air return opening 203 and the second air return opening 205 to exchange heat with the evaporator 30. The air after heat exchange enters the first chamber 209, and then enters the freezer 102 through the second air supply opening 204 and enters the refrigerator compartment 101 through the first air supply opening 202, making the air flow smoothly. The air can flow efficiently along the set path, thereby improving the refrigeration efficiency.

[0068] In some embodiments, the first chamber 209 communicates with the first air supply opening 202 and the second air supply opening 204, and the second chamber 210 communicates with the first air return opening 203 and the second air return opening 205.
