Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to an air-cooled horizontal freezer. Background Technology

[0002] Currently, most commercial glass-door freezers on the market are direct-cooling freezers. The most direct problem is that commercial freezers are used in harsh environments. First, they face high temperature and high humidity outdoor environments. Second, they are frequently opened by customers to select goods and by merchants to restock. Both of these scenarios cause severe frost formation on the internal walls and water vapor to form on the door of the direct-cooling freezer. Summary of the Invention

[0003] The purpose of this application is to provide an air-cooled horizontal freezer that uses a top air duct located at the top and protruding from the inner liner to support the heat insulation plate, thereby solving the problems of wall frost and water mist on the door in the prior art.

[0004] To achieve one of the aforementioned objectives, one embodiment of this application provides an air-cooled horizontal freezer, comprising:

[0005] The enclosure includes an inner liner that forms the accommodating compartments;

[0006] An evaporator compartment cover is provided in the receiving chamber and divides the receiving chamber into a refrigeration chamber and an evaporator compartment;

[0007] An air duct is located inside the inner liner and protrudes inward from the inner liner. The air duct and the inner liner cooperate to form an air duct cavity. The air duct cavity connects the refrigeration compartment and the evaporator compartment. The air duct includes two top air ducts near the top of the cabinet and located on opposite sides of the cabinet.

[0008] Insulation panels are supported by two top air ducts.

[0009] In one embodiment of this application, the heat insulation plate is provided with a plurality of ventilation holes.

[0010] In one embodiment of this application, two heat insulation panels are provided, and the sum of the lengths of the two heat insulation panels is greater than the length of the accommodating chamber in the length direction of the top air duct.

[0011] In one embodiment of this application, both heat insulation plates are provided with handle holes, and the two handle holes are far apart from each other.

[0012] In one embodiment of this application, the inner liner includes sidewalls formed around the accommodating chamber, and the sidewalls are provided with air ducts extending along the depth direction of the refrigeration chamber.

[0013] In one embodiment of this application, the air duct includes a groove formed by the recess in the side wall and a cover plate covering the groove. The groove and the cover plate together form an airflow channel, and the two ends of the airflow channel are connected to the refrigeration room.

[0014] In one embodiment of this application, the air duct includes a top air duct disposed near the top of the housing, the top air duct serving as an air outlet duct, the top air duct including a plurality of air outlets facing the refrigeration room, and the air inlet duct and the air outlets being arranged alternately.

[0015] In one embodiment of this application, the air duct includes a top air duct, a bottom air duct, and a vertical air duct. The top air duct and the bottom air duct are arranged at intervals in the vertical direction, and the vertical air duct connects the top air duct and the evaporator compartment.

[0016] In one embodiment of this application, the inner liner is provided with a stepped portion located at the bottom of one end of the accommodating chamber, the evaporator chamber and the stepped portion are parallel and adjacent in a first direction, and the vertical air duct is provided with a side air vent, which faces the stepped portion in the first direction.

[0017] In one embodiment of this application, an auxiliary air vent is provided at one end of the evaporator compartment cover near the vertical air duct.

[0018] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0019] In the air-cooled horizontal freezer provided in this application, the air duct is set to protrude from the inner liner, and a top air duct is set at the top. A heat insulation board is also set on the top air duct. The heat insulation board and the door work together to separate the interior of the refrigeration room from the outside. The temperature above the heat insulation board is higher than the temperature below the heat insulation board, but lower than the ambient temperature, forming a temperature gradient, which makes it less likely for water vapor to form on the door and affect the user's vision.

[0027] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise) and the spatially related descriptive terms used herein will be interpreted accordingly.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first air vent may be referred to as a second air vent, and similarly, a second air vent may be referred to as a first air vent, without departing from the scope of protection of this application.

[0030] This application provides an air-cooled horizontal freezer, such as... Figure 1 , 3 As shown in Figure 4, it includes a housing, an evaporator compartment cover 2 installed inside the housing, and an air duct 3.

[0031] The housing includes an inner liner 1 forming a receiving chamber, an evaporator compartment cover 2 disposed inside the receiving chamber, and dividing the receiving chamber into a refrigeration compartment 10 and an evaporator compartment 20.

[0032] The air duct 3 is located inside the inner liner 1 and protrudes inward from the inner liner 1. The air duct 3 and the inner liner 1 cooperate to form an air duct cavity 34, which connects the refrigeration chamber 10 and the evaporator chamber 20. The air duct 3 includes two top air ducts 31 located near the top of the box and on opposite sides of the box.

[0033] The heat insulation panel 4 is supported by two top air ducts 31.

[0034] The air duct 3 has a receiving groove with an opening facing the inner liner 1, and one end of the opening of the receiving groove of the air duct 3 is fixed to the inner liner 1, so that the inner liner 1 covers the opening to form the aforementioned air duct cavity 34.

[0035] In this application, the air duct 3 protrudes from the inner liner 1, and a top air duct 31 is provided near the top of the box to support the heat insulation board 4, so there is no need to set up a separate support structure to support the heat insulation board 4.

[0036] The heat insulation board 4 is located near the top of the cabinet, dividing the refrigeration chamber 10 into an isolation area above the heat insulation board 4 and below the door, and a refrigeration area below the heat insulation board 4.

[0037] The temperature in the cooling zone is extremely low due to the cooling effect of the evaporator in the evaporator compartment 20; the temperature in the isolation zone is between the cooling zone and the ambient temperature due to the influence of the cooling zone and the ambient temperature. That is, a temperature gradient is formed between the cooling zone, the isolation zone and the outside air, which reduces the temperature difference between the two sides of the door and prevents water mist or condensation from forming on the door at the low temperature of the cooling zone and the high temperature of the environment, thus avoiding affecting the user's vision.

[0038] In one embodiment of this application, the heat insulation plate 4 is provided with a plurality of ventilation holes 41.

[0039] When the door of the air-cooled horizontal freezer is opened and closed frequently, a large amount of hot air will still enter the isolation zone, causing water mist or condensation to form on the outer surface of the insulation board 4.

[0040] Ventilation holes 41 are provided on the heat insulation board 4 to allow heat exchange with the cooling zone when the door is opened, thereby reducing the temperature difference between the top and bottom of the heat insulation board 4 and preventing water mist or condensation. After the door is closed, the hot air in the isolation zone can also be carried away by the air circulation through the ventilation holes 41.

[0041] In one embodiment of this application, the vents 41 are arranged along the length of the air-cooled horizontal freezer and also along the width of the air-cooled horizontal freezer, with evenly spaced distribution, which facilitates the uniform entry of hot air from the isolation zone into the air circulation.

[0042] In one embodiment of this application, two heat insulation panels 4 are provided, and the sum of the lengths of the two heat insulation panels 4 is greater than the length of the accommodating chamber in the length direction of the top air duct 31.

[0043] The top air duct 31 can extend along the length of the air-cooled horizontal freezer or along its width, such as... Figure 4 In the middle, the top air duct 31 extends along the length of the air-cooled horizontal freezer, and the two heat insulation plates 4 are arranged along the length of the top air duct 31. Therefore, the length and width of the two heat insulation plates 4 are appropriate and they will not be slender structures that are difficult to transport.

[0044] If the sum of the lengths of the two heat insulation panels 4 along the length of the top air duct 31 is greater than the length of the accommodating chamber, then the two heat insulation panels 4 can partially overlap after covering the opening of the accommodating chamber. When the door is opened and items need to be retrieved, it is convenient to slide one of the heat insulation panels 4, and after sliding, the two heat insulation panels 4 can form a natural superimposed structure without the user having to lift the heat insulation panels 4 upwards.

[0045] In one embodiment of this application, both heat insulation plates 4 are provided with handle holes 42, and the two handle holes 42 are far apart from each other.

[0046] By opening a handle hole 42 on the heat insulation plate 4, it is convenient for the user to push the heat insulation plate 4 left and right through the handle hole 42.

[0047] like Figure 2 In the middle, the handle hole 42 on the left heat insulation plate 4 is located near the left end of the heat insulation plate 4, and the handle hole 42 on the right heat insulation plate 4 is located near the right end of the heat insulation plate 4.

[0048] When the left door is opened, the left heat insulation plate 4 is opened through the handle hole 42 on the left heat insulation plate 4. When the right door is opened, the right heat insulation plate 4 is opened through the handle hole 42 on the right heat insulation plate 4.

[0049] In one embodiment of this application, the inner liner 1 includes sidewalls 11 formed around the accommodating chamber, and the sidewalls 11 are provided with air ducts 5 extending along the depth direction of the refrigeration chamber 10.

[0050] The refrigeration chamber 10 is used to store items and refrigerate the stored items. When a large number of items are placed in the refrigeration chamber 10, the cold air above cannot be discharged and the cold air above accumulates, which easily causes condensation to form on the heat insulation plate 4 / door near the top.

[0051] A vertical air duct 5 is provided on the side wall 11, which can utilize the dynamic pressure difference between the top and bottom of the cooling chamber 10 to transfer the cold energy from the top to the bottom through the air duct 5, avoiding the accumulation of cold energy at the top and ensuring a uniform temperature distribution in the cooling chamber 10.

[0052] Multiple air ducts 5 are spaced along the length of the air-cooled horizontal freezer, making the cold air distribution in the refrigeration chamber 10 more uniform.

[0053] In one embodiment of this application, the air duct 5 includes a groove 111 formed by the recess of the side wall 11 and a cover plate 51 covering the groove 111. The groove 111 and the cover plate 51 together form an airflow channel 52, and the two ends of the airflow channel 52 are connected to the cooling room 10.

[0054] The side wall 11 can be made of sheet metal or plastic. Taking sheet metal as an example, the groove 111 is produced by stamping. Taking plastic as an example, the groove 111 is produced by injection molding or vacuum forming.

[0055] By pre-processing a groove 111 extending along the wind direction on the side wall 11, the depth and width of the groove 111 are optimized to ensure the formation of an airflow channel 52 of sufficient size; then, a cover plate 51 with appropriate rigidity and sealing performance is installed at the top of the groove 111, so that the airflow channel 52 is formed after the groove 111 and the cover plate 51 are closed.

[0056] In addition, by reasonably setting the gap between the cover plate 51 and the side wall 11, two different air vents are formed: the first air vent 521 is provided between the end near the top of the box and the side wall 11, while the second air vent 522 is formed between the cover plate 51 and the side wall 11 at the end away from the top of the box.

[0057] Figure 3 In the middle, the first air vent 521 is located above the second air vent 522. The first air vent 521 is used for air intake, and the second air vent 522 is used for air exhaust.

[0058] This allows airflow to flow from top to bottom from the inside of the side wall 11 without being blocked by the items stored in the refrigeration chamber 10.

[0059] Of course, the air duct 5 can also be set to protrude from the inner liner 1. By fixing a shell with an opening facing the inner liner 1 to the side wall 11, the shell and the side wall 11 enclose an airflow channel 52. A first air vent 521 and a second air vent 522 are opened at the top and bottom of the shell respectively so that the airflow channel 52 is connected to the refrigeration chamber 10.

[0060] In one embodiment of this application, the top air duct 31 serves as the air outlet duct 3. The top air duct 31 includes a plurality of air outlets facing the cooling room 10, and the air intake duct 5 and the air outlets are arranged alternately.

[0061] When the top air duct 31 is used as the outlet air duct 3, the intake air duct 5 and the outlet air vent are staggered. Specifically, it can be set as follows: Figure 4 In the case of a horizontal air-cooled freezer, the air duct 5 is located between two air outlets along the length of the freezer. In other words, the air outlets are located between two air ducts 5. This can prevent short-circuiting of the airflow. For example, the air blown out by the top air duct 31 may not have time to sink or cool the stored items before it is directly blown into the air duct 5 and transmitted to the bottom.

[0062] In addition, this staggered arrangement can create an ideal temperature gradient in the cooling room 10. Areas with excessive pressure are more likely to appear between adjacent air outlets. The air flows out through the air duct 5, ensuring the uniform distribution of cold air in the cooling room 10.

[0063] In one embodiment of this application, the air duct 3 includes a top air duct 31, a bottom air duct 32 and a vertical air duct 33. The top air duct 31 and the bottom air duct 32 are arranged at intervals in the vertical direction, and the vertical air duct 33 connects the top air duct 31 and the evaporator compartment 20.

[0064] The top air duct 31 and the bottom air duct 32 are horizontally arranged and are located near the top and bottom of the housing, respectively. The top air duct 31 is connected to the evaporator compartment 20 through the vertical air duct 33, and the bottom air duct 32 is directly connected to the evaporator compartment 20.

[0065] The air duct 3 can be an exhaust air duct 3 or a return air duct 3, or the air duct 3 set on one side of the box is the exhaust air duct 3, and the air duct 3 set on the other side of the box is the return air duct 3.

[0066] In one embodiment of this application, the inner liner 1 is provided with a step portion 12 located at the bottom of one end of the accommodating chamber, the evaporator chamber 20 is parallel and adjacent to the step portion 12 in a first direction, and the vertical air duct 33 is provided with a side air vent 331, which faces the step portion 12 in the first direction.

[0067] like Figure 4 In the middle, the evaporator compartment cover 2 is L-shaped, which together with the bottom wall of the inner liner 1 and the side wall of the step part 12 forms the evaporator compartment 20.

[0068] The step 12 is used to make way for the compressor of the refrigeration system. The evaporator compartment 20 and the step 12 are arranged side by side and adjacent to each other, which can raise part of the bottom wall of the refrigeration compartment 10 so that items stored above the evaporator compartment 20 and above the step 12 do not need to bend over excessively when they are retrieved.

[0069] The vertical air duct 33 is connected to the evaporator compartment 20. A side air vent 331 is provided on the vertical air duct 33, and the side air vent 331 faces the side of the step 12. When the air duct 3 is an outlet air duct 3, air is discharged above the step 12 through the side air vent 331 to avoid insufficient cooling above the step 12. When the air duct 3 is a return air duct 3, air is drawn from above the step 12 through the side air vent 331 to avoid untimely return air above the step 12.

[0070] In one embodiment of this application, an auxiliary air vent (not shown) is provided at one end of the evaporator compartment cover plate 2 near the vertical air duct 33.

[0071] Similarly, when the vertical air duct 33 connected to the evaporator compartment 20 is an outlet air duct 3, the auxiliary air outlet discharges air to provide sufficient cooling capacity to the top of the evaporator compartment 20. When the vertical air duct 33 connected to the evaporator compartment 20 is a return air duct 3, the auxiliary air outlet returns air, drawing the cold air above the evaporator compartment 20 into the evaporator compartment 20 to achieve return air.

[0072] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0073] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
