Description

Technical Field

[0001] The present application belongs to the technical field of refrigeration equipment, and in particular relates to an air duct module and a horizontal refrigerator. Background Art

[0002] A freezer is a specialized storage device used to store various items that require refrigeration. It keeps food and other items frozen and is available in both home and commercial formats. A freezer's refrigeration system consists of a compressor, condenser, capillary tubes, and evaporator. Through the continuous circulation of refrigerant, heat is drawn from the freezer to the outside, achieving a cooling effect.

[0003] To improve the temperature uniformity inside the freezer, air cooling can be used. A fan circulates cold air into the freezer. However, in related technologies, the different positions of multiple air vents result in unstable air volumes, which in turn easily leads to local temperature differences caused by varying cooling volumes, resulting in poor cooling performance inside the freezer.

[0050] A freezer is a specialized storage device used to store various items that require refrigeration. It keeps food and other items frozen and is available in both home and commercial formats. A freezer's refrigeration system consists of a compressor, condenser, capillary tubes, and evaporator. Through the continuous circulation of refrigerant, heat is drawn from the freezer to the outside, achieving a cooling effect.

[0051] In order to improve the uniformity of the temperature inside the freezer, air cooling can be used. The cold air is circulated into the freezer by a fan. However, in the related art, due to the different positions of multiple air vents, the air volume of the multiple air vents will be unstable, and local temperature differences caused by different local cooling amounts will still easily occur, resulting in poor cooling effect inside the freezer. The air duct module and horizontal freezer provided in the embodiments of the present application can improve the above problems. The air duct module and horizontal freezer provided in the embodiments of the present application can make the air volume blown to the refrigeration equipment roughly stable, thereby ensuring the cooling amount at different heights in the refrigeration equipment and improving the cooling effect of the refrigeration equipment.

[0052] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0053] See also Figure 1 and Figure 2 The embodiment of the present application also provides an air duct module 100. The air duct module 100 provided in the embodiment of the present application is mainly used in refrigeration equipment. The air duct module 100 provided in the embodiment of the present application can make the air volume blown to the refrigeration equipment roughly stable, thereby ensuring the cooling capacity at different heights in the refrigeration equipment and improving the refrigeration effect of the refrigeration equipment.

[0054] The air duct module 100 includes: a shell 120, a flow guide 130 and a flow guide 140. The shell 120 includes a front shell 121 and a rear shell 123. The front shell 121 and the rear shell 123 are connected to form an installation cavity 124. The front shell 121 is provided with a first air outlet 112 and a second air outlet 113 connected to the installation cavity 124. The rear shell 123 is provided with an air inlet 115. The flow guide 130 is provided in the installation cavity 124. The flow guide 140 is provided in the installation cavity 124, which can distribute the air volume to the first air outlet 112 and the second air outlet 113.

[0055] The air duct module 100 is applied to the refrigeration equipment and is installed in the cabinet 200 of the refrigeration equipment. It can make the air in the refrigeration equipment flow, so that the air in the refrigeration equipment can be blown to the frozen items after being cooled by the evaporator 320. That is, it can be considered that the air duct module 100 is mainly used to blow cold air into the refrigeration equipment, so that the cold air can circulate inside the refrigeration equipment, and ensure that the temperature in the same chamber of the refrigeration equipment is roughly the same as much as possible, reducing the temperature difference in the same chamber.

[0056] The housing 120 is the main body 220 of the entire duct module 100 and serves as the foundation for the module, providing a mounting base for other components of the module. Structures such as the flow guide 130 can be mounted on the housing 120, forming a cohesive unit for the duct module 100 and facilitating its installation and transportation. Furthermore, the housing 120 protects the flow guide 130 and other components, minimizing damage to them from external structures.

[0057] The flow guide 130 is mainly used for disturbing the flow so that the air can circulate in the refrigeration device, that is, the air in the refrigeration device can continuously flow to the evaporator 320, and then be blown to the frozen items again after being cooled by the evaporator 320.

[0058] Among them, the front shell 121 and the rear shell 123 are relative to the cabinet body 200 of the refrigeration equipment. Among the front shell 121 and the rear shell 123, the rear shell 123 is arranged closer to the cabinet body 200, that is, the rear shell 123 is located behind the front shell 121, and the front shell 121 and the rear shell 123 are connected to form an installation cavity 124.

[0059] The air inlet 115 is arranged on the rear shell 123, and the first air outlet 112 and the second air outlet 113 are arranged on the front shell 121. After being cooled by the evaporator 320, the air can be blown from the first air outlet 112 and the second air outlet 113 to the cabinet 200 of the refrigeration equipment through the guide member 130. The air blown out from the first air outlet 112 and the second air outlet 113 is cold air.

[0060] Since refrigeration equipment generally has a certain height, in order to allow the cold air to be blown to different heights within the cabinet 200 as much as possible, the first air outlet 112 and the second air outlet 113 can be arranged at different heights. That is, the first air outlet 112 can be arranged above the second air outlet 113, or the second air outlet 113 can be arranged above the first air outlet 112.

[0061] That is, the first air outlet 112 and the second air outlet 113 are located at different positions of the shell 120. After the guide member 130 is installed in the installation cavity 124, the position of the guide member 130 is determined. Due to factors such as the direction of the guide member 130, the rotation speed of the guide member 130, the position between the first air outlet 112 and the guide member 130, and the position between the second air outlet 113 and the guide member 130, the air volume of the first air outlet 112 and the second air outlet 113 is unstable.

[0062] A guide member 140 is provided in the installation cavity 124. The guide member 140 can guide the cold air entering the installation cavity 124 to the first air outlet 112 and the second air outlet 113 respectively. The air volume in the installation cavity 124 can be distributed by the guide member 140, so that the air volume of the cold air flowing to the first air outlet 112 and the second air outlet 113 can be roughly stable, thereby making the air volume blown to the refrigeration equipment roughly stable, thereby ensuring the cooling capacity at different heights in the refrigeration equipment and improving the refrigeration effect of the refrigeration equipment.

[0063] Specifically, since users generally place frozen items at the bottom first, there will be more frozen items piled up at the bottom, so the demand for cooling capacity at the bottom is greater. The guide member 140 can be used to guide more cooling capacity to the bottom of the refrigeration device. Furthermore, since the cabinet 200 of the refrigeration device is roughly rectangular (long), the duct module 100 is mounted on one side wall of the cabinet 200, so that the other side wall is farthest from the duct module 100. Consequently, the frozen items near the opposite side wall absorb less cooling capacity. Alternatively, the air outlet at the top can be enlarged so that the cold air flows to a farther location, thereby freezing the frozen items farther from the duct module 100.

[0064] In some embodiments, the air guide 140 is mounted on the rear housing 123 and is sealed with the front housing 121. Since the air flows from the air inlet 115 to the first air outlet 112 and the second air outlet, the air guide 140 can be mounted on the rear housing 123 and is sealed with the front housing 121, so that the rear housing 123, the front housing 121 and the air guide 140 can form an air guide channel to guide the cold air to the first air outlet 112 and the second air outlet 113 respectively.

[0065] Specifically, the air guide 140 and the rear shell 123 are integrally formed, which can reduce the processing costs of the air guide 140 and the rear shell 123, reduce the sealing process between the rear shell 123 and the air guide 140, and reduce the manufacturing cost.

[0066] In some embodiments, the air inlet 115 is staggered with the first air outlet 112 and the second air outlet 113. This means that in the direction from the front shell 121 to the rear shell 123, the air inlet 115 is staggered with the first air outlet 112, and the air inlet 115 is staggered with the second air outlet 113. This means that the air inlet 115 and the first air outlet 112 are not directly connected, and the air inlet 115 and the second air outlet 113 are not directly connected. In the process of flowing to the first air outlet 112 and the second air outlet 113, the cold air may collide with the front shell 121 or the rear shell 123, thereby losing kinetic energy. The guide member 140 is provided in the installation cavity 124 to guide the cold air in the installation cavity 124, thereby reducing the loss of the cold air's kinetic energy and allowing the cold air to blow farther into the cabinet 200, thereby maximizing the uniformity of the cooling capacity in the cabinet 200 and improving the cooling effect of frozen items.

[0067] See also Figure 3 、 Figure 4 and Figure 5 In some embodiments, the first air outlet 112 includes a first left air outlet 112c and a first right air outlet 112d, the second air outlet 113 includes a second left air outlet 113c and a second right air outlet 113d, and the air guide 140 includes a first air guide portion 142 and a second air guide portion 145. The first air guide portion 142 and the second air guide portion 145 are respectively arranged on both sides of the air inlet 115, the first air guide portion 142 is arranged corresponding to the first left air outlet 112c and the second left air outlet 113c, and the second air guide portion 145 is arranged corresponding to the first right air outlet 112d and the second right air outlet 113d.

[0068] There are two first air outlets 112, namely a first left air outlet 112c and a first right air outlet 112d, which are located at the same height of the front shell 121. There are two second air outlets 113, namely a second left air outlet 113c and a second right air outlet 113d, which are located at the same height of the front shell 121.

[0069] For ease of description, with the view from the front housing 121 toward the rear housing 123, the first left air vent 112c and the second left air vent 113c are respectively located on the left side of the air inlet 115, and the first right air vent 112d and the second right air vent 113d are respectively located on the right side of the air inlet 115. The first left air vent 112c is located above the second left air vent 113c, and the first right air vent 112d is located above the second right air vent 113d.

[0070] Similarly, the first guide portion 142 is located on the left side of the air inlet 115, and the second guide portion 145 is located on the right side of the air inlet 115. The first guide portion 142 is used to guide air to the first left air outlet 112c and the second left air outlet 113c, and the second guide portion 145 is used to guide air to the first right air outlet 112d and the second right air outlet 113d.

[0071] Specifically, the shape of the first air guide portion 142 can be set according to the height of the first left air port 112c and the second left air port 113c and their positions relative to the air guide member 130. Similarly, the shape of the second air guide portion 145 can be set according to the height of the first right air port 112d and the second right air port 113d and their positions relative to the air guide member 130.

[0072] In some embodiments, the minimum distance between the first flow guide portion 142 and the flow guide member 130 is a first distance, and the minimum distance between the second flow guide portion 145 and the flow guide member 130 is a second distance;

[0073] When the flow guiding member 130 turns from the second flow guiding portion 145 to the first flow guiding portion 142 , the first distance is greater than the second distance.

[0074] The guide member 130 may be a centrifugal wind wheel, and the air inlet 115 may be roughly circular. The guide member 130 may be installed at the air inlet 115. The first left air inlet 112c, the first right air inlet 112d, the second left air inlet 113c, and the second right air inlet 113d are roughly distributed at the four symmetrical corners of the air inlet 115. The distance between the first guide portion 142 and the guide member 130 may be roughly considered to be the distance between the first guide portion 142 and the air inlet 115. Specifically, the distance between the first guide portion 142 and the air inlet 115 refers to the distance between any point on the first guide portion 142 and the edge of the air inlet 115 along the radial direction of the air inlet 115. The minimum distance between the first guide portion 142 and the guide member 130 may be considered to be the minimum distance between the first guide portion 142 and the edge of the air inlet 115.

[0075] Since the first air guide portion 142 extends from the air inlet 115 to the first left air port 112 c and the second left air port 113 c respectively, it can be considered that the minimum distance between the first air guide portion 142 and the flow guiding member 130 is the first flow channel between the first air guide portion 142 and the air inlet 115 .

[0076] Similarly, the distance between the second air guide portion 145 and the air guide member 130 can be roughly considered to be the distance between the second air guide portion 145 and the air inlet 115. Specifically, the distance between the second air guide portion 145 and the air inlet 115 refers to the distance between any point on the second air guide portion 145 and the edge of the air inlet 115 along the radial direction of the air inlet 115. The minimum distance between the second air guide portion 145 and the air guide member 130 can be considered to be the minimum distance between the second air guide portion 145 and the edge of the air inlet 115.

[0077] Since the second guide portion 145 extends from the air inlet 115 to the first right air port 112 d and the second right air port 113 d respectively, it can be considered that the minimum distance between the second guide portion 145 and the flow guide member 130 is the second flow channel between the second guide portion 145 and the air inlet 115 .

[0078] The flow guide 130's rotation from the second guide portion 145 to the first guide portion 142 refers to the direction from the front housing 121 toward the rear housing 123, and the flow guide 130 rotates counterclockwise. During the rotation of the flow guide 130, air entering the accommodating chamber 211 from the air inlet 115 first flows toward the second guide portion, and then toward the first guide portion 142. If the first distance is greater than the second distance, it indicates that the first flow path is greater than the second flow path. Generally, the flow rate in the second guide portion 145 that passes first will be slightly greater than the flow rate in the first guide portion 142. The first flow channel is larger than the second flow channel, so that the wind speed flowing through the first guide part 142 and the second guide part 145 may be roughly the same, that is, the air volume blown out from the first left air port 112c, the second left air port 113c, the first right air port 112d and the second right air port 113d is roughly the same, and the air volume of different air outlets is made roughly the same as much as possible, so as to ensure that the cooling amount of cold air blown to various parts of the refrigeration equipment is the same as much as possible, thereby improving the freezing effect of the refrigeration equipment.

[0079] In some embodiments, the first guide portion 142 includes a first upper guide section 142a and a first lower guide section 142b, one end of the first upper guide section 142a and one end of the first lower guide section 142b are connected to form a first connection point 142c, one end of the first upper guide section 142a away from the first connection point 142c extends to the first left air outlet 112c, and one end of the first lower guide section 142b away from the first connection point 142c extends to the second left air outlet 113c.

[0080] The first connection point 142c is the point on the first air guide portion 142 closest to the air inlet 115. That is, the first connection point 142c is the point on the entire first air guide portion 142 closest to the guide member 130. The first upper guide section 142a extends from the air inlet 115 to below the first left air outlet 112c, directing cool air toward the first left air outlet 112c. The first lower guide section 142b extends from the air inlet 115 to above the second left air outlet 113c, directing cool air toward the second left air outlet 113c. Specifically, the first upper guide section 142a and the first lower guide section 142b are disposed between the first left air outlet 112c and the second left air outlet 113c.

[0081] The shape of the first upper guide section 142a can be straight, curved, or a combination of straight and curved shapes, and is not specifically limited. Similarly, the shape of the first lower guide section 142b can be straight, curved, or a combination of straight and curved shapes.

[0082] In some embodiments, along the height direction Z of the housing 120 , the inclination angle of the first upper guide section 142 a is greater than the inclination angle of the first lower guide section 142 b .

[0083] The height direction Z of the housing 120 refers to the height direction Z (vertical direction) of the entire air duct module 100 after being installed in the refrigeration equipment. Along the height direction Z of the housing 120, the inclination angle of the first upper air guide section 142a can be considered as the angle of the first upper air guide section 142a in the vertical direction. A larger inclination angle of the first upper air guide section 142a indicates a flatter first upper air guide section 142a and a slower air diversion. A smaller inclination angle of the first upper air guide section 142a indicates a steeper first upper air guide section 142a and a faster air diversion.

[0084] Similarly, the greater the inclination angle of the first lower guide section 142b in the height direction Z of the housing 120, the flatter the first lower guide section 142b is, and the slower the flow diversion is. The smaller the inclination angle of the first lower guide section 142b is, the steeper the first lower guide section 142b is, and the faster the flow diversion is.

[0085] The greater inclination angle of the first upper guide section 142a than the first lower guide section 142b indicates that the first upper guide section 142a is flatter than the first lower guide section 142b. Since the first upper guide section 142a is located above the first lower guide section 142b, the flow guide 130 turns from the first upper guide section 142a to the first lower guide section 142b. The flow velocity through the upper section is greater than that through the lower section. This means that the first lower guide section 142b is steeper, balancing the flow difference between the upper and lower sections, ensuring that the airflow volumes of the first left air outlet 112c and the second left air outlet 113c are approximately the same.

[0086] In some embodiments, the angle between the first upper guide section 142a and the first lower guide section 142b is 0 to 90 degrees. Since the first upper guide section 142a and the first lower guide section 142b are connected at the first connection point 142c and extend upward and downward respectively (in different directions), the smaller the angle between the first upper guide section 142a and the first lower guide section 142b, the closer the distance between the first upper guide section 142a and the first lower guide section 142b is, so that the space above the first upper guide section 142a and / or below the first lower guide section 142b is larger, and more cold air can be directed to the first left air outlet 112c and the second left air outlet 113c, thereby increasing the airflow volume of the first left air outlet 112c and the second left air outlet 113c.

[0087] Specifically, the included angle between the first upper guide section 142a and the first lower guide section 142b may be 25°, 30°, 35°, 45°, 60°, 65°, etc.

[0088] In some embodiments, the included angle between the first upper guide section 142a and the first lower guide section 142b is 30° to 60°.

[0089] In some embodiments, the second guide portion 145 includes a second upper guide section 145a and a second lower guide section 145b, one end of the second upper guide section 145a and one end of the second lower guide section 145b are connected to form a second connection point 145c, one end of the second upper guide section 145a away from the second connection point 145c extends to the first right air outlet 112d, and one end of the second lower guide section 145b away from the second connection point 145c extends to the second right air outlet 113d.

[0090] The second connection point 145c is the point on the second air guide portion 145 closest to the air inlet 115, that is, the second connection point 145c is the point on the entire second air guide portion 145 closest to the guide member 130. The second upper guide section 145a extends from the air inlet 115 to below the first right air outlet 112d, directing the cool air to the first right air outlet 112d. The second lower guide section 145b extends from the air inlet 115 to above the second right air outlet 113d, directing the cool air to the second right air outlet 113d. Specifically, the second upper guide section 145a and the second lower guide section 145b are disposed between the first right air outlet 112d and the second right air outlet 113d.

[0091] The shape of the second upper guide section 145a can be straight, curved, or a combination of straight and curved shapes, and is not specifically limited. Similarly, the shape of the second lower guide section 145b can be straight, curved, or a combination of straight and curved shapes.

[0092] In some embodiments, along the height direction Z of the housing 120 , the inclination angle of the second upper guide section 145 a is greater than the inclination angle of the second lower guide section 145 b .

[0093] The height direction Z of the housing 120 refers to the height direction Z (vertical direction) of the entire air duct module 100 after being installed in the refrigeration equipment. Along the height direction Z of the housing 120, the inclination angle of the second upper air guide section 145a can be considered as the angle of the second upper air guide section 145a in the vertical direction. The larger the inclination angle of the second upper air guide section 145a, the flatter the second upper air guide section 145a, and the slower the air diversion. The smaller the inclination angle of the second upper air guide section 145a, the steeper the second upper air guide section 145a, and the faster the air diversion.

[0094] Similarly, the greater the inclination angle of the second lower guide section 145b in the height direction Z of the housing 120, the flatter the second lower guide section 145b is, and the slower the flow diversion is. The smaller the inclination angle of the second lower guide section 145b is, the steeper the second lower guide section 145b is, and the faster the flow diversion is.

[0095] The greater inclination angle of the second upper guide section 145a than the second lower guide section 145b indicates that the second upper guide section 145a is flatter than the second lower guide section 145b. Since the second upper guide section 145a is located above the second lower guide section 145b, the flow guide 130 is directed from the first lower guide section 142b to the second upper guide section 145a. The flow velocity through the upper section is greater than that through the lower section. This is because the lower second lower guide section 145b is steeper, balancing the flow difference between the upper and lower sections, ensuring that the air volumes of the first right air outlet 112d and the second right air outlet 113d are approximately the same.

[0096] In some embodiments, the angle between the second upper guide section 145a and the second lower guide section 145b is 0 to 90 degrees. Since the second upper guide section 145a and the second lower guide section 145b are connected at the second connection point 145c and extend upward and downward respectively (in different directions), the smaller the angle between the second upper guide section 145a and the second lower guide section 145b, the closer the distance between the second upper guide section 145a and the second lower guide section 145b is, resulting in a larger space above the second upper guide section 145a and / or below the second lower guide section 145b, which can guide more cold air to the first right air outlet 112d and the second right air outlet 113d, thereby increasing the airflow volume of the first right air outlet 112d and the second right air outlet 113d.

[0097] Specifically, the included angle between the second upper guide section 145a and the second lower guide section 145b may be 25°, 35°, 40°, 45°, 55°, 60°, 65°, 70°, 80°, etc.

[0098] In some embodiments, the included angle between the second upper guide section 145a and the second lower guide section 145b is 40° to 70°.

[0099] In some embodiments, when the air guide member 130 is turned from the second air guide portion 145 to the first air guide portion 142 , the air guide angle of the first air guide portion 142 is smaller than the air guide angle of the second air guide portion 145 .

[0100] Among them, the wind guide angle of the first guide portion 142 refers to the angle between the first upper guide section 142a and the first lower guide section 142b. Since the first upper guide section 142a and the first lower guide section 142b are not in the same shape (part of the first upper guide section 142a is straight and part is arc-shaped, and the curvature of different sections may be different; part of the first lower guide section 142b is straight and part is arc-shaped, and the curvature of different sections may be different), the angle between the first upper guide section 142a and the first lower guide section 142b refers to the angle at the first connection point 142c.

[0101] The wind guide angle of the second air guide portion 145 refers to the angle between the second upper air guide section 145a and the second lower air guide section 145b. Since the second upper air guide section 145a and the second lower air guide section 145b are not in the same shape (part of the second upper air guide section 145a is straight and part is arc-shaped, and the curvature of different sections may be different; part of the second lower air guide section 145b is straight and part is arc-shaped, and the curvature of different sections may be different), the angle between the second upper air guide section 145a and the second lower air guide section 145b refers to the angle at the second connection point 145c.

[0102] The wind guide angle of the first guide portion 142 is smaller than that of the second guide portion 145 , which means that the distance between the first upper guide section 142a and the first lower guide section 142b is closer, and the space above and below the first upper guide section 142a and the first lower guide section 142b is relatively large. On the contrary, it shows that the distance between the second upper guide section 145a and the second lower guide section 145b is closer, and the space above and below the second upper guide section 145a and the second lower guide section 145b is relatively small. Since the second guide part 145 turns to the first guide part 142, the corresponding position of the second guide part 145 is the air inlet side, and the corresponding position of the first guide part 142 is the air outlet side. The air volume on the air inlet side is greater than the air volume on the air outlet side, and the space above and below the first upper guide section 142a and the first lower guide section 142b is relatively large, and the space above and below the second upper guide section 145a and the second lower guide section 145b is relatively small, which can balance the air volume flowing to the first left air outlet, the second left air outlet 113c, the first right air outlet and the second right air outlet, so that the air volume of the four air outlets is roughly balanced and stable.

[0103] In some embodiments, the air guide 140 further includes a third air guide portion 146 . The third air guide portion 146 is disposed below the air guide 130 and is configured to guide the air to the second left air outlet 113 c and the second right air outlet 113 d .

[0104] The third air guide portion 146 is located below the rear shell 123 and can guide the cold air to the second left air port 113c and the second right air port 113d, so that the air volume of the second left air port 113c and the second right air port 113d is roughly the same, thereby improving the uniformity of the air outlet as much as possible.

[0105] In some embodiments, the front shell 121 includes a first shell section 121a, a second shell section 121b and a third shell section 121c, the second shell section 121b is respectively connected to the first shell section 121a and the third shell section 121c, the rear shell 123 is connected to the first shell section 121a to form an installation cavity 124, the second shell section 121b and the third shell section 121c are used to form a fixed cavity 125 for installing the evaporator 320 with the cabinet body 200; wherein, the first air outlet 112 is arranged on the first shell section 121a, and the return air outlet 114 is arranged on the third shell section 121c.

[0106] See also Figure 6 The shell 120 includes a front shell 121 and a rear shell 123. The front shell 121 and the rear shell 123 are connected. The front shell 121 includes a first shell segment 121a, a second shell segment 121b and a third shell segment 121c. The first shell segment 121a is located above the second shell segment 121b, and the second shell segment 121b is located above the third shell segment 121c. The first shell segment 121a and the rear shell 123 form an installation cavity 124 for accommodating the guide member 130. The rear shell 123 is provided with an air inlet 115, and the return air outlet 114 is provided in the third shell segment 121c and is connected to the fixed cavity 125.

[0107] When the air in the accommodating chamber 211 enters the fixed chamber 125 through the return air port 114, it flows toward the air inlet 115 under the action of the flow guide 130. The air entering the fixed chamber 125 is cooled by the evaporator 320 before flowing toward the mounting chamber 124 and finally blown into the accommodating chamber 211 through the first air outlet 112. In other words, the evaporator 320 is disposed between the return air port 114 and the air inlet 115, providing cooling during the air circulation process. This ensures that the air blowing out of the first air outlet 112 is always cold air, thereby improving the freezing effect.

[0108] It should be noted that the evaporator 320 is fixed within the fixed cavity 125 formed by the second shell section 121b, the third shell section 121c, and the cabinet body 200, which facilitates the assembly of the duct module 100 and the evaporator 320. During assembly, the duct module 100 is first assembled into a whole, the evaporator 320 is mounted at a set position in the accommodating cavity 211, and the entire duct module 100 is then assembled into the accommodating cavity 211. The second shell section 121b and the third shell section 121c are then mounted over the evaporator 320, forming a closed fixed cavity 125 with the main body 220. This allows air within the accommodating cavity 211 to enter the fixed cavity 125 through the return air port 114, be cooled by the evaporator 320, and then flow to the first air outlet 112.

[0109] In some embodiments, the third shell segment 121c is protruded from the second shell segment 121b, and the return air port 114 is disposed at an end of the third shell segment 121c away from the second shell segment 121b.

[0110] The third shell segment 121c protrudes from the second shell segment 121b, meaning that the third housing 120 protrudes from the second shell segment 121b in the width direction X. Specifically, the third shell segment 121c is positioned to the left of the second shell segment 121b in the width direction X, closer to the center of the accommodating chamber 211. The return air port 114 is positioned at the end of the third shell segment 121c away from the second shell segment 121b, and the first air outlet 112 is positioned on the first shell segment 121a. It can be considered that, in the width direction X, of the return air port 114 and the first air outlet 112, the return air port 114 is positioned closer to the center of the accommodating chamber 211. This allows the gas within the accommodating chamber 211 to more easily enter the fixed chamber 125 through the return air port 114, allowing the gas to remain in the fixed chamber 125 for an extended period. This increases the heat exchange time with the evaporator 320, improves the cooling effect on the air, and thus enhances the freezing effect.

[0111] In some embodiments, the shell 120 also includes an insulation layer 126, which is arranged in the installation cavity 124 and is in contact with the front shell 121. Since the wind in the installation cavity 124 is cooled by the evaporator 320, the temperature is relatively low and has a certain temperature difference with the accommodating cavity 211. The insulation layer 126 is arranged on the inner side of the front shell 121, which can make the temperature of the front shell 121 roughly consistent with the temperature of the accommodating cavity 211, thereby reducing the risk of condensation on the front shell 121 due to the temperatures inside and outside the front shell 121.

[0112] In addition, the housing 120 further includes a sealing layer 127 . The sealing layer 127 is disposed at the connection between the front housing 121 and the rear housing 123 to seal the front housing 121 and the rear housing 123 .

[0113] See also Figure 7 and Figure 8Based on the same inventive concept, an embodiment of the present application further provides a horizontal freezer 10 , which includes a cabinet body 200 and the above-mentioned air duct module 100 , and the air duct module 100 is installed in the cabinet body 200 .

[0114] The horizontal freezer 10 is mainly used for refrigerating items. The cabinet body 200 is the main body 220 structure of the entire horizontal freezer 10. It can provide an installation basis for structures such as the air duct module 100, compressor 310, evaporator 320, condenser, etc., and can also protect the above-mentioned electronic components.

[0115] The cabinet 200 includes a main body 220 and a door 230 connected to the main body 220. The door 230 covers the opening of the main body 220. A refrigerated chamber 211 is provided within the main body 220, and the items to be refrigerated are placed within the refrigerated chamber 211. The cold air blown out by the air duct module 100 freezes the items. The main body 220 includes an inner liner 221 and an outer shell 223. The space between the inner liner 221 and the outer shell 223 is filled with a foam layer. An electrical chamber 215 is located between the inner liner 221 and the outer shell 223, which accommodates a compressor 310. The electrical control box 340 is also located within the electrical chamber 215.

[0116] In some embodiments, the cabinet 200 includes a main body 220 and a door 230 rotatably connected to the main body 220 . Of the first left air vent 112 c and the first right air vent 112 d , the first right air vent 112 d is closer to the connection between the door 230 and the main body 220 .

[0117] The main body 220 is roughly a rectangular parallelepiped. For ease of description, the height direction Z, width direction X, and thickness direction Y are defined separately. When the chest freezer 10 is in use, the vertical direction is the height direction Z, and the projection of the main body 220 in the vertical direction is a rectangle. The direction along the long side is the width direction X, and the direction along the wide side is the thickness direction Y. The main body 220 and the door body 230 are pivotally connected, generally at the opening of the main body 220, specifically at one side along the width direction X, so that one end of the door body 230 rotates along the thickness direction Y during opening.

[0118] Since the first left air vent 112c and the first right air vent 112d are both disposed near the top of the cabinet 200, that is, the first left air vent 112c and the first right air vent 112d are disposed near the opening of the cabinet 200, and the first left air vent 112c and the first right air vent 112d are spaced apart in the width direction X, the first right air vent 112d is closer to the connection between the door body 230 and the main body 220, that is, the first left air vent 112c is closer to the door opening side. The air volume of the first right air vent 112d is greater than the air volume of the first left air vent 112c, so that the air volume of the first left air vent 112c is smaller during the door opening process, reducing the user's sense of wind during the door opening process and improving the user experience.
