[0026] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. In addition, for the convenience of describing the refrigerator 1, the side of the refrigerator 1 provided with the door 16 can be described as the front of the refrigerator 1, and the side opposite to the door 16 can be described as the back of the refrigerator 1, that is, Figure 1 The back side of the refrigerator 1 is shown in FIG. The refrigerator 1 of the present application can be used as a display refrigerator 1. Of course, it can also be a refrigerator 1 with other functions, and the above is not restrictive.

[0027] like Figure 1 As shown, the present application provides a freezer 1, comprising a first box body 11 and a second box body 12, wherein the first box body 11 and the second box body 12 are stacked up and down and the first box body 11 is arranged above the second box body 12, the freezer 1 also comprises a first drain pipe 110 and a drain port 13, the drain port 13 is arranged below the second box body 12, the first drain pipe 110 connects the drain end 113 of the first box body 11 with the drain port 13, and an insulation layer is arranged between the first drain pipe 110 and the second box body 12, and the insulation layer is used to separate the first drain pipe 110 from the second box body 12. Since the first box body 11 is arranged above the second box body 12, and the drain outlet 13 is arranged below the second box body 12, the first drain pipe 110 needs to bypass the second box body 12 and be connected with the drain outlet 13. In order to prevent the water flowing in the first drain pipe 110 from freezing due to the low temperature of the second box body 12, an insulation layer is arranged between the first drain pipe 110 and the second box body 12. The insulation layer can prevent the first drain pipe 110 from contacting the second box body 12, and at the same time, it can block the cold air of the second box body 12 from being transmitted to the first drain pipe 110, thereby preventing the water in the first drain pipe 110 from freezing.

[0028] It should be noted that the “first box body 11 ”, “second box body 12 ” and similar terms used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0029] It should also be noted that the directions and positional relationships indicated by “above” and “below” are based on the attached Figure 1 In the orientation or position relationship shown, the direction indicated by the x-direction is upward, and the direction opposite to the x-direction is downward. The upward and downward are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the first box body 11 and the second box body 12 must have a specific orientation or be constructed and operated in a specific orientation.

[0030] In addition, the freezer 1 of the present application includes two boxes stacked up and down, and the first box 11 and the second box 12 can be used as a refrigerator or a freezer. Of course, one of them can be set as a refrigerator and the other as a freezer. The above is not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the scope of protection of the present application. For the convenience of subsequent introduction, the following is an example of setting the first box 11 as a refrigerator and the second box 12 as a freezer.

[0031] In one embodiment, if Figure 2 , Figure 3As shown, the first drain pipe 110 includes a first water pipe 111 and a second water pipe 112 connected to each other, the first water pipe 111 is connected to the drain end 113 of the first box body 11, and the second water pipe 112 is connected to the drain port 13. An insulating layer is arranged between the first water pipe 111 and the back side 122 of the second box body 12. The back side 122 of the second box body 12 is a side of the second box body 12 away from the door 16 of the freezer 1. Compared with arranging the first water pipe 111 on the side close to the second box body 12, arranging the first water pipe 111 on the side close to the back side 122 of the second box body 12 will not increase the width of the freezer 1, thereby reducing the overall occupied space of the freezer 1. Figure 3 As shown, the distance between the first water pipe 111 and the plane where the back side 122 of the second box body 12 is located gradually increases from the first end 111a of the first water pipe 111 to the second end 111b. The first end 111a is the end where the first water pipe 111 is connected to the drainage end 113 of the first box body 11, and the second end 111b is the end where the first water pipe 111 is connected to the second water pipe 112.

[0032] When the second box 12 is set as a freezer, the second box 12 can release more cold air. In order to ensure that the water in the first water pipe 111 does not freeze in the process of flowing to the second water pipe 112, the first water pipe 111 is tilted, and the distance between the first water pipe 111 and the plane where the back side 122 of the second box 12 is located gradually increases from the first end 111a of the first water pipe 111 to the second end 111b. At this time, the distance between the first end 111a and the back side 122 of the second box 12 is the shortest, and the distance between the second end 111b and the back side 122 of the second box 12 is the farthest, that is, Figure 3 As shown in , the distance d1 between the first water pipe 111 near the first end 111a and the second box 12 is smaller than the distance d2 between the first water pipe 111 near the second end 111b and the second box 12. At this time, the water in the first water pipe 111 is getting farther and farther away from the second box 12 during the process of flowing to the second water pipe 112, and thus, the probability of the water in the first water pipe 111 being frozen by the cold air released by the second box 12 is getting lower and lower. Therefore, the tilted arrangement of the first water pipe 111 further reduces the risk of the water in the first water pipe 111 freezing.

[0033] It should be noted that the “connection” between the first water pipe 111 and the second water pipe 112 may be a fixed connection, a detachable connection, or an integral connection, and therefore, may be configured according to the needs of those skilled in the art.

[0034] It should also be noted that the first drain pipe 110 can be configured to include a first water pipe 111 and a second water pipe 112, and the distance between the first water pipe 111 and the plane where the back side 122 of the second box body 12 is located gradually increases from the first end 111a to the second end 111b. Of course, the first drain pipe 110 can also be configured in other forms. For example, the distance between any position of the first water pipe 111 and the back side 122 of the second box body 12 is the same, and the first water pipe 111 is away from the back side 122 of the second box body 12. At this time, the distance between the first water pipe 111 and the back side 122 of the second box body 12 can be set according to the needs of technical personnel in this field, and at this time, the first water pipe 111 and the drainage end 113 of the first box body 11 need to be connected with an additional water pipe.

[0035] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the direction indicated by the x direction is upward, and the direction indicated by the y direction is the first direction, that is, the direction perpendicular to the door 16 of the second box body 12, and also the direction perpendicular to the back side 122 of the second box body 12. Figure 1 The freezer 1 shown in the figure is a projection diagram of the freezer 1 along the first direction. Along the first direction, the second end 111b of the first water pipe 111 is located below the second box body 12. Under the above arrangement, even if water leakage occurs at the connection position between the first water pipe 111 and the second water pipe 112, the leaked water will not fall on the second box body 12 to cause the back side 122 of the second box body 12 to freeze. In addition, since the drain outlet 13 is also below the second box body 12, it is more convenient to connect the second water pipe 112 to the first water pipe 111 and the drain outlet 13, thereby preventing the second box body 12 from affecting the installation of the second water pipe 112.

[0036] In one embodiment, along the first direction, the end of the second water pipe 112 connected to the first water pipe 111 is higher than the drain port 13, that is, Figure 1 It is shown that the height h1 of the second end 111b of the first water pipe 111 is higher than the height h2 of the drain outlet 13. At this time, when the water in the first water pipe 111 flows to the second water pipe 112, the water can flow directly from the second water pipe 112 to the drain outlet 13 under the action of gravity. Therefore, the above arrangement does not require additional drainage power to discharge the water in the first box 11 to the drain outlet 13, thereby saving costs.

[0037] In one embodiment, if Figure 4 , Figure 5As shown, the second housing 12 is provided with a second drain pipe 121, and a multi-way pipe 14 is provided at the drain port 13. The multi-way pipe 14 at least includes a first water inlet 141, a second water inlet 142 and a water outlet 143. The first water inlet 141 is connected to the first drain pipe 110, the second water inlet 142 is connected to the second drain pipe 121, and the water outlet 143 is connected to the drain port 13. At this time, the water in the first drain pipe 110 is discharged from the first water inlet 141 to the water outlet 143 and then discharged from the drain port 13, and the water in the second drain pipe 121 is discharged from the second water inlet 142 to the water outlet 143 and then discharged from the drain port 13. When the first drain pipe 110 or the second drain pipe 121 is blocked by ice, the drainage of the other drain pipe will not be affected. Therefore, the setting of the multi-way pipe 14 ensures efficient drainage. In addition, when a drain pipe is blocked, the user can quickly and accurately determine the blocked drain pipe and clear it.

[0038] It should be noted that the water outlet 143 of the multi-way pipe 14 and the drain port 13 can be connected by threaded fitting, and of course, can also be connected by snap-fit ​​or other means. It should also be noted that the multi-way pipe 14 can include more than the first water inlet 141 and the second water inlet 142. When there can be other drainage points in the freezer 1, the multi-way pipe 14 can also include other water inlets to connect with other drainage points, and then guide the water from other drainage points to other water inlets and then collect them at the water outlet 143 for discharge. The above is not restrictive and can be set according to the needs of those skilled in the art. The above is within the protection scope of this application. The above is not restrictive.

[0039] In one embodiment, if Figure 4 As shown, the connection between any two of the first water pipe 111, the second water pipe 112, the drainage end 113 of the first box 11, and the drainage port 13 is detachable. When any of the first water pipe 111 and the second water pipe 112 is blocked or damaged, only the first water pipe 111 or the second water pipe 112 can be disassembled and the corresponding water pipe can be cleaned or replaced. When the drainage end 113 of the first box 11 or the drainage port 13 is blocked, the first water pipe 111 and the drainage end 113 of the first box 11 can be disassembled and the drainage end 113 of the first box 11 can be cleaned, or the second water pipe 112 and the drainage port 13 can be disassembled and the drainage port 13 can be cleaned. The above arrangement can reduce the difficulty of repairing the freezer 1, thereby saving the maintenance cost.

[0040] In one embodiment, if Figures 6 to 8As shown, the refrigerator 1 further includes a connection assembly 15, which includes a connection member 151, one end of which is provided with a flange 1511, which extends into the drainage end 113 of the first box body 11 and abuts against the drainage end 113 of the first box body 11, and the other end of the connection member 151 extends from the drainage end 113 and is detachably connected to the first water pipe 111. The flange 1511 of the connection member 151 abuts against the drainage end 113 to prevent the drainage end 113 of the first box body 11 from leaking, thereby ensuring that the water in the first box body 11 flows into the first water pipe 111 along the connection member 151, and the detachable connection between the connection member 151 and the first water pipe 111 can also facilitate subsequent maintenance, and at the same time, it can also facilitate the installation of the first water pipe 111 and the first box body 11.

[0041] In one embodiment, if Figures 6 to 8 As shown, the connection assembly 15 also includes a locking member 152, the locking member 152 is provided with an internal thread 1521, the connection member 151 is provided with an external thread 1512, the locking member 152 is screwed on the connection member 151, and the drainage end 113 is located between the locking member 152 and the flange 1511. The locking member 152 can make the connection member 151 and the drainage end 113 tightly combined, thereby further avoiding water leakage at the drainage end 113. It should be noted that the locking member 152 and the connection member 151 of the present application are connected by threads, and of course, other connection methods can also be set, such as clamping, which is not restrictive and can be set according to the needs of those skilled in the art, and the above are all within the protection scope of the present application.

[0042] In one embodiment, if Figures 6 to 8 As shown, the locking member 152 is provided with a plurality of protrusions 1522, and the protrusions 1522 are arranged along the circumference of the locking member 152, and the end of the protrusion 1522 close to the drainage end 113 is flush with the end of the locking member 152 close to the drainage end 113. The arrangement of the protrusions 1522 can save more effort when screwing the locking member 152, and at the same time, the flush arrangement of the protrusions 1522 and the end of the locking member 152 close to the drainage end 113 can more easily determine whether the locking member 152 is screwed into place. It should be noted that the plurality of protrusions 1522 on the locking member 152 means that two or more protrusions 1522 are provided. In addition, the "circumferential" in the circumferential arrangement of the protrusions 1522 along the locking member 152 is based on the attached Figure 7 The orientation or position relationship shown is only for the convenience of describing the present application and simplifying the description.

[0043] In one embodiment, if Figure 7 , Figure 8As shown, the connection assembly 15 further includes a gasket 153, which is sleeved on the connection member 151 and located between the flange 1511 and the drainage end 113. The gasket 153 is disposed in the first box body 11 and located between the flange 1511 and the drainage end 113 to further prevent the first box body 11 from leaking water from the drainage end 113.

[0044] In one embodiment, the thickness of the insulation layer is not less than 40 mm. The thickness of the insulation layer is not less than 40 mm, which can ensure that there is a sufficient distance between the first drain pipe 110 and the second box body 12 to prevent the water in the first drain pipe 110 from being frozen by the cold air released by the second box body 12.

[0045] In one embodiment, the heat insulating layer is a foaming layer, and the foaming layer is polyurethane foam, or the foaming layer is formed by foaming a mixture of polyether, cyclopentane and isocyanate. The heat insulating layer formed by foaming is dense and has a good heat insulating effect. Of course, in addition to using the above-mentioned foaming material, the foaming layer can also be formed by foaming other foaming materials. The above is not limiting and can be set according to the needs of those skilled in the art, and the above are all within the scope of protection of this application.
