Description

Technical Field

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

[0002] Most existing horizontal freezers are single-walled units and cannot be partitioned. Some horizontal freezers achieve partitioning by adding dividers in the middle or by adding food trays, but adding dividers in the middle takes up cabinet volume and increases costs; adding food trays can only achieve partitioning near the cabinet opening, and partitioning at the bottom of the cabinet is still not possible. Summary of the Invention

[0003] The purpose of this application is to provide a horizontal freezer that solves the problem that existing horizontal freezers cannot achieve space-saving design and bottom partitioning.

[0004] To achieve one of the above-mentioned objectives, one embodiment of this application provides a horizontal freezer, comprising:

[0005] The housing includes an inner liner forming a refrigeration chamber and an outer shell fitted over the inner liner. A compressor compartment is formed at the bottom of the housing. The inner liner has a stepped portion located at the bottom of one end of the refrigeration chamber. The stepped portion includes a stepped top plate located above the compressor compartment.

[0006] An evaporator compartment is formed within a refrigeration room. The evaporator compartment and the step portion are arranged side by side and adjacent to each other in a first direction. The top of the evaporator compartment is higher than the top plate of the step portion.

[0007] In one embodiment of this application, the inner liner further includes a bottom plate. In a first direction, the bottom plate is located on the side of the evaporator compartment away from the step. In the vertical direction, the height difference between the evaporator compartment and the top plate of the step is not greater than 1 / 2 of the height difference between the top plate of the step and the bottom plate.

[0008] In one embodiment of this application, the inner liner further includes two first side walls, which are parallel to a first direction; the horizontal freezer further includes an evaporator compartment cover plate fixed to the inner liner, which, together with the two first side walls and the step portion, encloses the evaporator compartment, and the evaporator compartment cover plate includes a first compartment side wall and a second compartment side wall that are both perpendicular to the first direction.

[0009] In one embodiment of this application, the lower end of the first cabin sidewall is fixedly connected to the step portion and extends upward from the step portion.

[0010] In one embodiment of this application, a partition is also included, the partition extending upward from the top of the first compartment sidewall and / or the top of the second compartment sidewall.

[0011] In one embodiment of this application, an air duct is further included. The air duct is fixed relative to the first sidewall and communicates with the evaporator compartment. The air duct includes an upper air duct, a lower air duct, and a vertical air duct. The upper air duct and the lower air duct are arranged at intervals in the vertical direction. The vertical air duct connects the upper air duct and the evaporator compartment. The upper air duct and the lower air duct are both arranged horizontally and have multiple air outlets arranged at intervals.

[0012] In one embodiment of this application, the upper air duct and the vertical air duct are disposed between the inner liner and the outer shell, and the lower air duct is disposed on the side of the inner liner away from the outer shell.

[0013] In one embodiment of this application, an evaporator and a fan assembly are further disposed within the evaporator chamber, wherein the evaporator and the fan assembly are arranged side by side in a second direction, wherein the second direction is horizontal and perpendicular to the first direction.

[0014] In one embodiment of this application, the fan assembly includes a volute and an evaporating fan disposed within the volute. The volute is provided with a first air inlet facing the evaporator and a second air inlet and a third air inlet that are open upwards and horizontally, respectively.

[0015] In one embodiment of this application, the volute is at least partially disposed between the inner liner and the outer liner; the volute includes a front cover with the first air vent and a rear cover opposite to the front cover, the end of the front cover near the second air vent extends toward the outer liner to be flush with the first side wall of the inner liner, and the end of the rear cover near the third air vent extends toward the interior of the refrigeration room to be flush with the first side wall of the inner liner.

[0016] In one embodiment of this application, a drainage hole is provided at the bottom of the volute.

[0017] In one embodiment of this application, the air duct is configured as an air outlet duct, and the vertical air duct is provided with a side air outlet. In a first direction, the air outlet of the side air outlet is directed toward one side of the stepped portion.

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

[0019] In the horizontal freezer provided in this application, the evaporator compartment and the stepped section are arranged side by side in the horizontal direction, and the height of the evaporator compartment is set to be higher than the height of the stepped section, so that a low-lying area is formed above the stepped section to achieve partitioning. At the same time, because the evaporator compartment is taller, its thickness along the first direction can be reduced, thereby reducing the space occupied by the evaporator compartment.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0039] 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.

[0040] 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.

[0041] 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 sidewall may be referred to as a second sidewall, and similarly, a second sidewall may be referred to as a first sidewall, without departing from the scope of protection of this application.

[0042] This application provides a horizontal freezer, such as... Figures 1-3 As shown, the device includes a housing and an evaporator compartment 30. The housing includes an inner liner 1 and an outer shell 2. The inner liner 1 forms a refrigeration chamber 11. The outer shell 2 is fitted over the inner liner 1. A compressor compartment is formed at the bottom of the housing. The inner liner 1 has a stepped portion 12. The stepped portion 12 is located at the bottom of one end of the refrigeration chamber 11. The stepped portion 12 includes a stepped top plate 121 located above the compressor compartment.

[0043] Evaporator compartment 30 is formed in refrigeration compartment 11. Evaporator compartment 30 and step portion 12 are arranged side by side and adjacent to each other in a first direction. The top of evaporator compartment 30 is higher than the top plate 121 of step portion 121.

[0044] The step section 12 inside the refrigeration compartment 11 of the horizontal freezer is reserved for the space to house the compressor, that is, a compressor compartment is set below the step section 12.

[0045] In this application, the evaporator compartment 30 is arranged side by side and adjacent to the step portion 12 in the horizontal direction, and the top height of the evaporator compartment 30 is set higher than the top plate 121 of the step portion, so that the space above the step portion 12 is isolated by the evaporator compartment 30.

[0046] This application utilizes the adjustment of the position and height of the evaporator compartment 30 to achieve the division of the refrigeration chamber 11. On the one hand, it avoids the need to design a thicker partition due to the fixed problem, thus occupying space in the refrigeration chamber 11.

[0047] On the other hand, the evaporator compartment 30 was changed from being located above the step 12 to being located beside the step 12. The evaporator compartment 30 occupies part of the bottom space of the refrigeration compartment 11, freeing up the space above the step 12, making it easier for users to access.

[0048] Furthermore, since the evaporator compartment 30 is designed to be relatively high, its thickness can be designed to be relatively thin, and the space size of the refrigeration compartment 11 will not be reduced due to the increase in the height of the evaporator compartment 30.

[0049] In some embodiments of this application, the inner liner 1 further includes a bottom plate 13. In a first direction, the bottom plate 13 is located on the side of the evaporator compartment 30 away from the step portion 12. In the vertical direction, the height difference between the evaporator compartment 30 and the top plate 121 of the step is not greater than 1 / 2 of the height difference between the top plate 121 of the step and the bottom plate 13.

[0050] The base plate 13 is the bottom wall of the refrigeration chamber 11 located on the side of the evaporator compartment 30 away from the step 12. The height of the evaporator compartment 30 is the difference in vertical distance between the top of the evaporator compartment 30 and the base plate 13.

[0051] The portion of the evaporator compartment 30 that is higher than the top plate 121 of the step is no more than 1 / 2 of the height difference between the top plate 121 and the bottom plate 13, that is, the height of the evaporator compartment 30 is no more than 1.5 times the height of the step portion 12.

[0052] This is due to considerations regarding the height of the evaporator 6 installed inside the evaporator compartment 30. If the evaporator 6 has a certain height, setting the evaporator compartment 30 too high would occupy space inside the refrigeration room 11.

[0053] In some embodiments of this application, the inner liner 1 further includes two first sidewalls 14, which are parallel to a first direction and are disposed opposite to each other.

[0054] The horizontal freezer also includes an evaporator compartment cover 3 fixed to the inner liner 1, and the evaporator compartment cover 3, together with the two first side walls 14 and the step portion 12, forms an evaporator compartment 30.

[0055] The evaporator compartment cover 3 includes a first compartment sidewall 31 and a second compartment sidewall 33, both of which are perpendicular to the first direction.

[0056] like Figure 3 In the middle, the first side wall 14 are the two longer side walls of the horizontal freezer. When the freezer is used in the bedroom, these two first side walls 14 are the front wall and the back wall.

[0057] In addition to the first sidewall 14, the inner liner 1 also includes two second sidewalls 15 that are connected to and opposite to the two first sidewalls 14. The step portion 12 is disposed against one of the second sidewalls 15. The two second sidewalls 15 are the left wall and the right arm.

[0058] That is, the first direction is the left and right direction.

[0059] The evaporator compartment cover 3 also includes a top wall 32, with the first compartment side wall 31 and the second compartment side wall 33 connected to its two ends respectively.

[0060] The inner liner 1 also includes a support member 4, which includes a side part 41 and a bottom part 42.

[0061] The side portion 41 is formed as part of the side wall of the evaporator compartment 30 near the step portion 12, and is also formed as the side wall of the step portion 12 near the evaporator compartment 30. The bottom portion 42 is disposed at the bottom of the evaporator compartment 30 and formed on its bottom wall.

[0062] like Figure 3 In the middle, the top of the side portion 41 bends toward the step portion 12 and forms a mounting slot 411, into which the top plate 121 of the step is inserted.

[0063] In some embodiments of this application, the lower end of the first compartment sidewall 31 is fixedly connected to the step portion 12 and extends upward from the step portion 12.

[0064] This allows the first compartment side wall 31, the second compartment side wall 33, and the top wall 32 of the evaporator compartment cover plate 3 to form the evaporator compartment 30 together with the two first side walls 14 and the side part 41 and bottom part 42 of the support member 4.

[0065] In some embodiments of this application, the horizontal freezer also includes a partition 34 that extends upward from the top of the first compartment sidewall 31 and / or the top of the second compartment sidewall 33.

[0066] A partition 34 extends upward from the top of the first compartment sidewall 31 and / or the top of the second compartment sidewall 33, further dividing the space within the refrigeration compartment 11. For example:

[0067] When a partition 34 is installed extending upward from the top of the first compartment sidewall 31, the space inside the refrigeration compartment 11 is divided into: the space above the step 12 and the space above the evaporator compartment 30 + the space of the evaporator compartment 30 on the side away from the step 12.

[0068] When a bulkhead 34 is installed extending upward from the top of the second compartment sidewall 33, for example... Figure 3 As shown, the space inside the refrigeration chamber 11 is divided into: the space of the evaporator compartment 30 on the side away from the step 12 and the space above the step 12 + the space above the evaporator compartment 30.

[0069] Furthermore, the space above the stepped section 12 can be divided into sections due to the higher evaporator compartment 30.

[0070] When partitions 34 are provided extending upward from the top of the first compartment sidewall 31 and the top of the second compartment sidewall 33, the space inside the refrigeration chamber 11 is divided into: the space above the step 12, the space above the evaporator chamber 30, and the space of the evaporator chamber 30 away from the step 12. The division of the space above the step 12 and the space above the evaporator chamber 30 is more precise.

[0071] Furthermore, the bulkhead 34 can be integrally formed with the first compartment sidewall 31 and / or the second compartment sidewall 33, so there is no need to consider the issue of fixing the bulkhead 34. The thickness of the bulkhead 34 is approximately the same as that of the first compartment sidewall 31 and / or the second compartment sidewall 33, so it will not cause the problem of occupying space in the refrigeration compartment 11.

[0072] In some embodiments of this application, the horizontal freezer also includes an air duct, which is fixed relative to the first side wall 14 and communicates with the evaporator compartment 30.

[0073] The air duct includes an upper air duct 51, a lower air duct 52 and a vertical air duct 53. The upper air duct 51 and the lower air duct 52 are arranged at intervals in the vertical direction. The vertical air duct 53 connects the upper air duct 51 and the evaporator compartment 30. Both the upper air duct 51 and the lower air duct 52 are arranged horizontally and have multiple air outlets arranged at intervals.

[0074] The upper air duct 51 and the lower air duct 52 extend along the first direction, and both ends of the upper air duct 51 and the lower air duct 52 are close to the second side wall 15. In other words, the upper air duct 51 and the lower air duct 52 extend from one end of the refrigeration room 11 to the other end.

[0075] The air duct can be either an exhaust air duct or a return air duct. Two horizontal air ducts, one high and one low, are set on the first side wall 14 to ensure the uniformity of airflow in the refrigeration room 11 in both the length and height directions.

[0076] Of course, on one of the two first sidewalls 14, the air duct may be provided with only one upper air duct 51 and connected to the evaporator compartment 30 through the vertical air duct 53, or only one lower air duct 52 may be provided and connected to the evaporator compartment 30.

[0077] You can also set only one located in, such as Figure 3 The horizontal air duct between the upper-middle air duct 51 and the lower-middle air duct 52, or in Figure 3 A horizontal air duct is added between the upper-middle air duct 51 and the lower-middle air duct 52.

[0078] In some embodiments of this application, the upper air duct 51 and the vertical air duct 53 are disposed between the inner liner 1 and the outer shell 2, and the lower air duct 52 is disposed on the side of the inner liner 1 away from the outer shell 2.

[0079] In horizontal freezers, food baskets are usually hung above the refrigeration compartment 11 to increase partitioning. The upper air duct 51 and the vertical air duct 53 are hidden between the inner liner 1 and the outer shell 2, so they will not interfere with the installation of the food baskets, nor will the protruding air ducts at the top reduce the distance between the front and back of the food baskets.

[0080] The downdraft duct 52 protrudes from the outer shell 2 into the refrigeration chamber 11, and can serve as a mounting bracket for the food basket, thus sharing some of the support force for the food basket.

[0081] Regarding the installation of the upwind duct 51 and the downwind duct 52, the specifics are as follows: Figure 4 middle.

[0082] The upper air duct 51 includes an upper air duct shell 511 and an upper air duct cover 512. The upper air duct shell 511 forms an upper air duct cavity with an opening facing the refrigeration chamber 11, and the upper air duct cover 512 covers the opening of the upper air duct cavity.

[0083] The upper air duct shell 511 is provided with a first upper slot 5111 and a first lower slot 5112. The first upper slot 5111 and the first lower slot 5112 are located at the top and bottom of the upper air duct shell 511, and the openings of the first upper slot 5111 and the first lower slot 5112 both face the refrigeration chamber 11.

[0084] The upper air duct cover 512 is provided with an upper flange 5121 and a lower flange 5122. The upper flange 5121 and the lower flange 5122 are provided at the top and bottom of the upper air duct cover 512. The upper flange 5121 and the lower flange 5122 are respectively provided in the first upper slot 5111 and the first lower slot 5112, so that the upper air duct cover 512 is fixed to the upper air duct shell 511.

[0085] The bottom of the upper air duct housing 511 extends downward near the opening of the upper air duct cavity and is provided with a fixing slot 5113. The top of the first side wall 14 is disposed in the fixing slot 5113, so that the upper air duct 51 is fixed to the first side wall 14. Furthermore, the upper air duct cover plate 512 is flush with the first side wall 14.

[0086] The downdraft duct 52 includes a downdraft duct cover 521, an upper reinforcing strip 522, and a lower reinforcing strip 523.

[0087] The cross-section of the downdraft cover 521 is C-shaped, and both the upper reinforcing strip 522 and the lower reinforcing strip 523 are L-shaped.

[0088] One end of the L-shaped upper reinforcing strip 522 is fixed to the first side wall 14, and the other end has a second upper slot 5221 with an opening facing the refrigeration chamber 11.

[0089] One end of the L-shaped lower reinforcing strip 523 is fixed to the first side wall 14, and the other end has a second lower slot 5231 with an opening facing the refrigeration chamber 11.

[0090] The upper and lower ends of the downdraft cover 521 are respectively inserted into the second upper slot 5221 and the second lower slot 5231, so that the downdraft cover 521 is fixed to the first side wall 14 and together with the first side wall 14 to form a downdraft cavity.

[0091] like Figure 7 In the middle, the vertical air duct 53 includes a vertical air duct shell 531 and a vertical air duct cover 532. The vertical air duct shell 531 forms a vertical air duct cavity with an opening facing the refrigeration chamber 11, and the vertical air duct cover 532 covers the opening of the vertical air duct cavity.

[0092] Similar to the structure of the upper air duct 51, the vertical air duct cover 532 is provided with a left flange and a right flange. The left flange and the right flange are provided on the left and right sides of the vertical air duct cover 532, respectively, and are positioned inside the vertical air duct cavity for positioning the vertical air duct cover 532.

[0093] like Figure 5 In the middle, the upper air duct shell 511, the vertical air duct shell 531 and the support member 4 are integrated into one piece, which is a plastic part and serves as part of the inner liner 1.

[0094] The upper air duct cover plate 512 and the vertical air duct cover plate 532 are integrated and are installed together on the upper air duct cavity and the vertical air duct cavity.

[0095] The inner liner 1 also includes a U-shaped large enclosure 16, a U-shaped small enclosure 18, and a small bottom plate 19. The large enclosure 16, the bottom plate 13, the small enclosure 18, and the small bottom plate 19 are all sheet metal parts.

[0096] The inner liner 1 is composed of the large enclosure panel 16, the bottom plate 13, the small enclosure panel 18, the small bottom plate 19, the upper air duct shell 511, the vertical air duct shell 531, and the support member 4.

[0097] The evaporator compartment 30 is located on the side away from the step portion 12 in the refrigeration chamber 11 formed by the large enclosure 16 and the bottom plate 13; the portion above the step portion 12 in the refrigeration chamber 11 is formed by the small enclosure 18 and the small bottom plate 19.

[0098] In some embodiments of this application, such as Figure 6 The horizontal freezer provided in this application also includes an evaporator 6 and a fan assembly 7, which are disposed within the evaporator compartment 30.

[0099] In the second direction, the evaporator 6 and the fan assembly 7 are arranged side by side, wherein the second direction is horizontal and perpendicular to the first direction.

[0100] Evaporator 6 is located in evaporator compartment 30 to provide cooling capacity to cooling room 11, and fan assembly 7 is used to blow the cooling capacity generated by evaporator 6 to cooling room 11.

[0101] The fan assembly 7 is arranged side by side with the evaporator 6 in the second direction, which can reduce the space of the evaporator compartment 30.

[0102] In some embodiments of this application, such as Figure 9 , 10 The fan assembly 7 includes a volute 71 and an evaporator fan 72. The evaporator fan 72 is disposed inside the volute 71. The volute 71 is provided with a first air outlet 713, a second air outlet 714 and a third air outlet 715. The first air outlet 713 faces the evaporator 6, the second air outlet 714 opens upward, and the third air outlet 715 opens horizontally.

[0103] The first air vent 713 faces the evaporator 6 and is used to draw the cold energy of the evaporator 6 into the volute 71 and then discharge it through the second air vent 714 and the third air vent 715.

[0104] Alternatively, the air in the cooling chamber 11 can be blown to the evaporator 6 through the first air vent 713 for heat exchange.

[0105] The second air vent 714 and the third air vent 715 are connected to the vertical air duct 53 and the downwind duct 52, respectively.

[0106] The fan assembly 7 can be set up in one set or in two sets.

[0107] When a fan assembly 7 is set up, a duct is also set up, and it is located on the same side of the evaporator 6 as the fan assembly 7.

[0108] When two sets of fan assembly 7 are set, such as Figure 7 In the middle, two sets of fan assemblies 7 are respectively set on both sides of the evaporator 6, and correspondingly, two air ducts are respectively fixed to two oppositely arranged first side walls 14.

[0109] When two sets of fan components 7 are set, both air ducts can be either supply air ducts or return air ducts, or one can be a supply air duct and the other a return air duct.

[0110] In some embodiments of this application, the volute 71 is at least partially disposed between the inner liner 1 and the outer shell 2; the volute 71 includes a front cover 711 and a rear cover 712, the front cover 711 has a first air vent 713, and the rear cover 712 is disposed opposite to the front cover 711.

[0111] like Figure 7 In the middle, the front cover 711 extends towards the outer shell 2 from the end near the second air vent 714 until it is flush with the first side wall 14 of the inner liner 1.

[0112] like Figure 8 In the middle, the rear cover 712 extends towards the interior of the refrigeration chamber 11 at one end near the third air vent 715 until it is flush with the first side wall 14 of the inner liner 1.

[0113] It should be noted that the "front" and "rear" in the front cover 711 and rear cover 712 here are not directional. The front cover 711 refers only to the cover on the side closer to the evaporator 6, and the rear cover 712 refers only to the cover on the side away from the evaporator 6. This is different from the directional indication of the front and rear in the front and rear walls of the aforementioned refrigeration chamber 11.

[0114] The vertical air duct 53 extends from the inner liner 1 to the outer shell 2 and is disposed between the inner liner 1 and the outer shell 2. The wall of the vertical air duct 53 near the refrigeration chamber 11 is flush with the inner liner 1.

[0115] The lower air duct 52 extends from the inner liner 1 into the refrigeration compartment 11, and the wall of the lower air duct 52 near the outer shell 2 is flush with the inner liner 1.

[0116] The vertical air duct 53 and the downwind duct 52 are not coplanar, which also means that the second air outlet 714 and the third air outlet 715, which are connected to the vertical air duct 53 and the downwind duct 52 respectively, are also not coplanar.

[0117] The volute 71 is at least partially disposed between the inner liner 1 and the outer liner 2. The front cover 711 of the volute 71 is disposed on the side of the inner liner 1 near the refrigeration chamber 11, and the rear cover 712 of the volute 71 is disposed on the side of the inner liner 1 near the outer liner 2.

[0118] Extend the end of the front cover 711 near the second air vent 714 toward the outer shell 2 until it is flush with the first side wall 14, so that the second air vent 714, like the vertical air duct 53, is located between the inner liner 1 and the outer shell 2.

[0119] Extend the end of the back cover 712 near the third air vent 715 toward the side of the refrigeration chamber 11 until it is flush with the first side wall 14, so that the third air vent 715, like the downdraft duct 52, is located on the side of the inner liner 1 near the refrigeration chamber 11.

[0120] In some embodiments of this application, a drainage hole 716 is provided at the bottom of the volute 71.

[0121] The evaporator fan 72 may frost during the evaporator 6 cooling process, and defrosting is required by the heating wire.

[0122] To prevent defrost water from being unable to drain and causing secondary icing during the subsequent evaporator 6 cooling process, which could affect the operation of the evaporator fan 72, a drain hole 716 is added to the bottom of the volute 71 to drain the defrost water.

[0123] In some embodiments of this application, the rear cover 712 of the volute 71 is provided with a wire outlet 717 for the outlet of the evaporator fan 72.

[0124] In some embodiments of this application, the air duct is configured as an air outlet duct, and the vertical air duct 53 is provided with a side air outlet 533. In the first direction, the air outlet 533 is directed toward the side of the step portion 12.

[0125] When the air duct is set as an outlet air duct, the vertical air duct 53 not only connects to the evaporator compartment 30, but also has a side air outlet 533. The air outlet 533 is directed from the vertical air duct 53 to the stepped part 12 and is blown out at an angle.

[0126] This allows the cold air generated by the evaporator 6 to be blown into the space above the step 12, avoiding the risk of insufficient cold air in the space above the step causing the product to melt.
