[0031] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The terms used in this embodiment, such as "upper," "above," "lower," and "below," which indicate spatial relative positions, are used for ease of explanation 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 position" may be intended to include different orientations of the equipment during use or operation besides those shown in the figures. For example, in this embodiment, "upper," "lower," "left," "right," "horizontal," and "vertical" all refer to the spatial relative positions of the horizontal freezer under normal operating conditions.

[0033] The terms "first," "second," "third," "fourth," etc., used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] To enable those skilled in the art to better understand the technical solutions of this utility model, the appendices in the embodiments of this utility model will be described below. Figures 1 to 10 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0035] One embodiment of this utility model provides a horizontal freezer, particularly a wind-cooled horizontal freezer.

[0036] Reference Figure 1The freezer includes a cabinet 10 and a door 20, with the door 20 located above the cabinet 10. The door 20 may include, for example, transparent glass, through which the user can observe the items stored inside the cabinet 10.

[0037] Reference Figure 2 and Figure 3 The enclosure 10 includes, for example, a shell 11, a foam layer (not shown), and an inner liner 12. A gap 13 is provided between the shell 11 and the inner liner 12, and the foam layer is filled in the gap 13. The foam layer is made of thermal insulation material.

[0038] Reference Figure 3 and Figure 4 The inner liner 12 is embedded in the accommodating space of the outer shell 11. The inner liner 12 includes a bottom plate 121, two first side plates 122 and two second side plates 123. The two first side plates 122 are parallel, the two second side plates 123 are parallel, and the two first side plates 122 and the two second side plates 123 are perpendicular to the bottom plate 121.

[0039] The base plate 121, two first side plates 122 and two second side plates 123 enclose a storage room 14, which is used to store items.

[0040] It should be noted that both the first side plate 122 and the second side plate 123 extend vertically. Furthermore, the first side plate 122 and the second side plate 123 can be a single-piece cast wall or a cast wall formed by splicing multiple plates. This embodiment does not specifically limit this aspect.

[0041] Reference Figures 5 to 7 The inner liner 12 has a stepped portion 124, which includes a top wall 1241 and a bottom wall 1244.

[0042] The top wall 1241, the bottom wall 1244, and the base plate 121 of the steps are arranged in the horizontal direction.

[0043] In the vertical direction, the bottom wall 1244 of the step is higher than the base plate 121, and the bottom wall 1244 of the step is lower than the top wall 1241 of the step.

[0044] The horizontal freezer also includes an evaporator compartment 30, which is located inside the inner liner 12, that is, the evaporator compartment 30 is located on one side of the storage compartment 14.

[0045] The evaporator compartment 30 is formed on the upper side of the bottom wall 1244 of the step, and the bottom wall 1244 of the step is directly set as the bottom wall of the evaporator compartment 30, so that the bottom of the evaporator compartment 30 is higher than the bottom plate 121 and lower than the top wall 1241 of the step.

[0046] There is a height difference between the bottom of the evaporator compartment 30 and the bottom plate 121 of the inner liner 12. This height difference allows water in the evaporator compartment 30 to drain more smoothly, and the bottom of the evaporator compartment 30 is less likely to accumulate water.

[0047] The step portion 124 also includes a first step sidewall 1242, which connects the top wall 1241 and the bottom wall 1244 of the step. The top wall 1241 extends generally horizontally, and the first step sidewall 1242 extends generally vertically, with the top wall 1241 and the first step sidewall 1242 being perpendicular to each other.

[0048] Thus, the top wall 1241 of the step and the side wall 1242 of the first step make the inner liner 12 form a stepped structure that is concave inward toward the storage chamber 14.

[0049] The evaporator compartment 30 and the step portion 124 are arranged horizontally. The evaporator compartment 30 and the step portion 124 are arranged side by side, so that the top of the evaporator compartment 30 and the step portion 124 together form a storage area, making reasonable use of the space in the storage room 14.

[0050] Please refer to again Figure 3 and Figure 4 The horizontal freezer also includes a compressor compartment 40, and the stepped portion 124 of the inner liner 12 is configured as a reserved space for installing a compressor. The compressor compartment 40 is formed between the outer shell 11 and the inner liner 12 at the stepped portion 124.

[0051] The compressor compartment 40 is located below the top wall 1241 of the step, and the compressor compartment 40 is located on the side of the evaporator compartment 30 away from the bottom plate 121.

[0052] The compressor compartment 40 and the evaporator compartment 30 are arranged side by side. The evaporator and the compressor are close to each other, which makes it easy to connect pipes and also makes it easy to guide the water in the evaporator compartment 30 into the compressor compartment 40.

[0053] The bottom wall 1244 of the steps gradually slopes downward from the bottom plate 121 toward the compressor chamber 40. The evaporator chamber 30, with its sloping bottom, can guide the water flow, allowing it to be discharged into the compressor chamber 40 more quickly.

[0054] In an alternative embodiment, the bottom of the evaporator compartment 30 may also be horizontal.

[0055] The compressor compartment 40 is equipped with a water receiving part 41, and the bottom of the evaporator compartment 30 is higher than the water receiving part 41. The water receiving part 41 in the compressor compartment 40 can be a water tank, water tank or other structure, mainly used to store water from the evaporator compartment 30.

[0056] Specifically, the bottom of the evaporator compartment 30 gradually slopes downward toward the water receiving part 41. The sloping bottom of the evaporator compartment 30 toward the water receiving part 41 can smoothly guide the water in the evaporator compartment 30 to the side of the water receiving part 41, making drainage fast and smooth.

[0057] The ratio of the maximum distance H1 between the bottom wall 1244 and the base plate 121 to the minimum distance H2 between the bottom wall 1244 and the top wall 1241 of the step is in the range of 1:2 to 1:6.

[0058] The maximum distance H1 between the bottom wall 1244 of the step and the base plate 121 is the distance between the highest point of the bottom wall 1244 of the step and the base plate 121.

[0059] The minimum distance H2 between the bottom wall 1244 and the top wall 1241 of the step is the distance between the highest point of the bottom wall 1244 and the top wall 1241 of the step.

[0060] With this configuration, the distance between the bottom wall 1244 and the top wall 1241 of the step is relatively large, and sufficient space is reserved between the bottom wall 1244 and the top wall 1241 of the step for installing the evaporator.

[0061] At the same time, there will be no large height difference between the bottom wall 1244 of the step and the bottom plate 121, and there will be no large height difference between the top of the evaporator compartment 30 and the top wall 1241 of the step, making the internal structure of the freezer more compact and making full use of the space of the freezer.

[0062] The inner liner 12 also includes a second stepped sidewall 1243, which connects the bottom plate 121 and the stepped bottom wall 1244. The second stepped sidewall 1243 extends generally in a vertical direction, that is, the second stepped sidewall 1243 is located on the highest side of the bottom of the evaporator compartment 30, and the bottom of the evaporator compartment 30 forms a height difference with the bottom plate 121 through the second stepped sidewall 1243.

[0063] Reference Figure 7 A water receiving tray 32 is formed on the bottom wall 1244 of the step. The water receiving tray 32 can be formed directly during the forming process of the bottom wall 1244 of the step.

[0064] The bottom wall 1244 of the step, the first side wall 1242 of the step, and the second side wall 1243 of the step are integrally formed. Furthermore, the bottom wall 1244 of the step, the first side wall 1242 of the step, and the second side wall 1243 of the step are all made of plastic.

[0065] The drip tray 32 is formed directly on the bottom wall 1244 of the step. The drip tray 32 is made of metal and can be a sheet metal part. Before forming the inner liner 12, the drip tray 32 can be pre-set in the forming mold. During the forming process of the inner liner 12, the drip tray 32 is formed directly on the inner liner 12.

[0066] The metal drip tray 32 has good thermal conductivity, allowing frost to melt quickly after falling onto it. Due to structural differences, thermal resistance exists at the connection between the drip tray 32 and the plastic material, making it difficult for heat from the drip tray 32 to transfer to the plastic component. The heat from defrosting the drip tray 32 is also not easily conducted through the inner liner 12 to the storage compartment 14.

[0067] Reference Figures 8 to 10 The water receiving tray 32 includes a flow guiding part 321 and two receiving parts, which are integrally formed.

[0068] Along the front-back direction of the inner liner 12, two receiving parts are respectively provided on both sides of the guide section 321. The two receiving parts are referred to as the first receiving part 322 and the second receiving part 323.

[0069] The two receiving portions gradually slope downwards towards the guide portion 321; that is, the first receiving portion 322 slopes downwards towards the guide portion 321, and the second receiving portion 323 slopes downwards towards the guide portion 321. The slope angles of the first receiving portion 322 and the second receiving portion 323 are the same. Thus, the water receiving tray 32 is arranged in a V-shape.

[0070] The first receiving part 322 and the second receiving part 323 are used to receive the frost that melts and falls from the evaporator. The inclined first receiving part 322 and the second receiving part 323 can also guide the water from the melted frost to the guide part 321 to achieve rapid defrosting and drainage.

[0071] Along the front-to-back direction of the horizontal freezer, the lengths of the first receiving portion 322 and the second receiving portion 323 can be the same or different, and the lengths of the first receiving portion 322 and the second receiving portion 323 are set according to the shape of the evaporator. In this embodiment, the length of the first receiving portion 322 is greater than the length of the second receiving portion 323.

[0072] The flow guide 321 includes a flow guide bottom wall 3211 and two flow guide side walls. Along the front-rear direction of the inner liner 12, two receiving parts are respectively arranged on both sides of the flow guide 321. The two flow guide side walls are respectively referred to as the first flow guide side wall 3212 and the second flow guide side wall 3213.

[0073] The two guide sidewalls gradually slope downward toward the guide bottom wall 3211, that is, the first guide sidewall 3212 slopes downward toward the guide bottom wall 3211, and the second guide sidewall 3213 slopes downward toward the guide bottom wall 3211. The first guide sidewall 3212 and the second guide sidewall 3213 have the same slope angle.

[0074] The inclined first guide sidewall 3212 and second guide sidewall 3213 can further serve the purpose of drainage, making the drainage speed of the guide section 321 faster.

[0075] The inclination angle α of the guide sidewall is greater than the inclination angle β of the receiving part. More specifically, the angle difference between the inclination angle α of the guide sidewall and the inclination angle β of the receiving part is 10° to 50°.

[0076] The inclination angle α of the guide sidewall is the angle between the extending plane containing the guide sidewall and the horizontal plane. The inclination angle β of the receiving part is the angle between the extending plane containing the receiving part and the horizontal plane.

[0077] Because the angle of inclination of the guide sidewall is greater, the flow velocity of the water at the bottom of the evaporator chamber 30 will further increase as it flows from the guide sidewall to the guide bottom wall 3211, so as to achieve rapid drainage.

[0078] From the bottom plate 121 toward the top plate of the step, the dimensions of the guide bottom wall 3211 gradually decrease along the front-to-back direction of the freezer.

[0079] A drain outlet 125 is provided on the side wall 1242 of the first step. The drain outlet 125 protrudes outward from the side wall 1242 of the first step. The drain outlet 125 is integrally formed with the side wall 1242 of the first step.

[0080] The drain outlet 125 is positioned to match the guide section 321. In the front-to-back direction of the horizontal freezer, the drain outlet 125 is located within the guide section 321. More specifically, the drain outlet 125 is positioned to match the bottom wall 3211 of the guide section.

[0081] The diameter of the drain outlet 125 gradually decreases from the evaporator compartment 30 toward the top wall 1241 of the step. That is, the flow channel inside the drain outlet gradually decreases along the direction of drainage.

[0082] Water from the guide section 321 can smoothly enter from the larger diameter end of the drain outlet 125. During the drainage process, the flow channel inside the drain outlet 125 gradually narrows, and the water flow rate gradually increases, achieving rapid drainage.

[0083] The maximum diameter of the drain outlet 125 is not less than the minimum width of the guide bottom wall 3211. Water in the guide section 321 can flow smoothly from the end with the larger diameter of the drain outlet 125 to achieve rapid drainage.

[0084] A drain pipe (not shown) can be connected between the drain outlet 125 and the water receiving part 41, and water in the evaporator compartment 30 can be discharged to the water receiving part 41 through the drain pipe.

[0085] As a further limitation, refer to Figure 7 The horizontal freezer also includes an evaporator cover 50, which is fixed to the inner liner 12. The evaporator cover 50, together with the two first side plates 122 and the step portion 124, forms an evaporator compartment 30. The evaporator is installed inside the evaporator compartment 30.

[0086] The evaporator cover 50 includes a side wall 51 and a top wall 52, which can be integrally formed.

[0087] In one embodiment, the top wall 52 of the compartment and the top wall 1241 of the step can be flush, forming a storage platform in the storage room 14 composed of the top wall 52 of the compartment and the top wall 1241 of the step, which facilitates users to store and retrieve items.

[0088] In one embodiment, the top wall 52 may be higher than the top wall 1241 of the step, so that the space above the step portion 124 is isolated by the evaporator compartment 30.

[0089] Therefore, the storage chamber 14 can be divided into sections by adjusting the position and height of the evaporator compartment 30.

[0090] This invention employs a stepped inner liner 12 structure, arranging the evaporator compartment 30 and the stepped portion 124 side-by-side, resulting in a more compact internal structure for the freezer. The bottom wall 1244 of the stepped section at the bottom of the evaporator compartment 30 is higher than the bottom plate 121, allowing for faster drainage of water from melting frost within the evaporator compartment 30, thus ensuring effective drainage. Furthermore, the bottom wall 1244 is lower than the top wall 1241, creating space within the stepped portion 124 for evaporator installation, thus making efficient use of the horizontal freezer's installation space and further enhancing its compact internal structure.

[0091] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
