Description

Technical Field

[0001] The utility model relates to a refrigerator. Background Art

[0002] For a long time, existing refrigerators generally use iron tube heaters to defrost the evaporator. As the volume of the water accumulation tray is reduced to increase the volume ratio of the compartment, the iron tube heater on the water accumulation tray is too close to the inner tank. The heat from the iron tube heater is quickly transferred to the inner tank, causing the temperature of the inner tank to greatly exceed the maximum temperature limit of the inner tank material. After a long time, the life of the inner tank is shortened, and it is easy to deform and bubble, posing a safety hazard. Utility Model Content

[0003] The utility model is the result of careful research in view of the above problems, and its purpose is to provide a refrigerator capable of reducing the temperature of the inner tank during defrosting to improve safety.

[0004] In order to achieve the above-mentioned purpose, the refrigerator involved in the utility model includes a box body, a compressor, an inner tank, a water collection tray, an evaporator, a heater and a heat-insulating component. The water collection tray is located below the evaporator, the heater heats the evaporator to defrost the evaporator, and the heat-insulating component insulates the heater from the inner tank.

[0005] That is, the utility model designs a new heat-insulating component, which effectively suppresses the temperature rise of the inner tank through the performance of the heat-insulating component, so that the constituent materials of the inner tank meet the maximum temperature limit of the material, thereby ensuring safety. Specifically, the constituent materials of the inner tank can also meet the maximum temperature limit of the material (for example, 85°C), greatly improving the safety of the refrigerator.

[0006] In addition, in the refrigerator involved in the above-mentioned utility model, the inner liner may include a first inner liner arranged on the back of the evaporator and a second inner liner located at the bottom of the evaporator, and the heat insulating component insulates the heater from the first inner liner and the second inner liner. In this way, the heat insulating component has the effect of lowering the temperature of the inner liner on the back of the evaporator and the inner liner in the water pan area below the evaporator, thereby lowering the temperature of the inner liner, especially the inner liner on the back of the evaporator and the inner liner in the water pan area below the evaporator during defrosting to improve safety.

[0007] In addition, in the refrigerator involved in the above-mentioned utility model, the heat insulating component can also be attached to the water collection tray and the first inner pot, and the heater can be mounted on the heat insulating component. In this way, by attaching the designed heat insulating component around the water collection tray and the first inner pot, the temperature rise of the inner pot, especially the inner pot on the back of the evaporator and the inner pot in the water collection tray area under the evaporator, can be further effectively suppressed, so that the constituent material of the inner pot more reliably meets the maximum temperature limit of the material, thereby further ensuring safety.

[0008] In addition, in the refrigerator involved in the above-mentioned utility model, the water accumulation tray may include a first inclined surface and a second inclined surface, and the heat insulation component may include: a first insulation surface attached along the first inclined surface, a second insulation surface attached along the second inclined surface, and a third insulation surface extending upward from the edges of the first insulation surface and the second insulation surface and attached along the first liner. In this way, by attaching the heat insulation component along the first inclined surface and the second inclined surface of the water accumulation tray and the surface of the first liner respectively, the temperature rise of the liner, especially the liner on the back of the evaporator and the liner in the water accumulation tray area below the evaporator, can be further effectively suppressed, so that the constituent material of the liner more reliably meets the maximum temperature limit of the material, thereby further ensuring safety.

[0009] In addition, in the refrigerator of the utility model, an opening may be formed at the intersection of the first insulation surface and the second insulation surface, so that the defrosted water of the evaporator can flow into the water storage pan through the opening formed at the intersection of the first insulation surface and the second insulation surface.

[0010] In addition, in the refrigerator involved in the above-mentioned utility model, the heat insulating component may also include a fixing portion, and the heat insulating component is fixed by the fixing portion being engaged with a protrusion provided on the inner container. In this way, the heat insulating component can be firmly fixed by a simple structure. However, the fixing method of the heat insulating component is not limited to this, and may be any method such as bonding with an adhesive, screw fastening, welding, etc.

[0011] In addition, in the refrigerator of the utility model, the heat insulating component may be made of aluminum. In this way, by making the heat insulating component of aluminum, the heat insulating performance of the heat insulating component can be reliably achieved. However, the constituent material of the heat insulating component is not limited to aluminum, and may be any material such as plastic, resin, etc. that can achieve a heat insulating effect.

[0012] In addition, in the refrigerator related to the above-mentioned utility model, the heater may be an iron pipe heater. In this way, by forming the heater with a meandering iron pipe, the heater can be arranged in a narrow space to save space.

[0013] In addition, in the refrigerator of the utility model, the compressor may be located at the top of the refrigerator. However, the installation position of the compressor is not limited to the top of the refrigerator, but may also be the bottom of the refrigerator.

[0014] According to the utility model, a refrigerator can be provided which can reduce the temperature of the inner container during defrosting to improve safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Furthermore, it should be understood that the embodiments listed in this specification are only for illustrative purposes and are not intended to limit the present invention to these embodiments. On the contrary, as understood by those skilled in the art, the present invention includes various alternatives, modifications and equivalents.

[0024] In this specification, it should be understood that terms such as “includes,” “comprising,” and “having” refer to the existence of stated features, quantities, steps, operations, elements, parts, or a combination thereof, but do not exclude the existence of one or more other features, quantities, steps, operations, elements, parts, or a combination thereof.

[0025] Figure 1 It is a schematic diagram showing a schematic structure of a refrigerator according to the present embodiment. Figure 2 It is a front view showing a schematic structure of the refrigerator involved in this embodiment. Figure 3 It is a front view showing a schematic structure of the refrigerator involved in this embodiment.

[0026] like Figure 1 to Figure 3 As shown, the refrigerator 1 involved in this embodiment includes a box body 10, a compressor (not shown), an inner tank 20, a water collection tray 30, an evaporator 40, a heater 50 and a heat insulation component 60.

[0027] The water collecting pan 30 is located below the evaporator 40 and receives defrosting water of the evaporator 40. The heater 50 heats the evaporator 40 to defrost the evaporator 40. The heat insulating member 60 insulates the heater 50 from the inner container 20.

[0028] That is, the utility model designs a new heat-insulating component, which effectively suppresses the temperature rise of the inner tank through the performance of the heat-insulating component, so that the constituent materials of the inner tank meet the maximum temperature limit of the material, thereby ensuring safety. Specifically, the constituent materials of the inner tank can also meet the maximum temperature limit of the material (for example, 85°C), greatly improving the safety of the refrigerator.

[0029] As a specific example of the heat insulating member 60 isolating the heater 50 from the inner container 20, Figure 2 As shown, the inner liner 20 includes a first inner liner 201 disposed on the back of the evaporator 40 and a second inner liner 202 located at the bottom of the evaporator 40, and the heat insulating component 60 insulates the heater 50 from the first inner liner 201 and the second inner liner 202. In this way, the heat insulating component has the effect of lowering the temperature of the inner liner on the back of the evaporator and the inner liner in the water collection tray area at the bottom of the evaporator, thereby lowering the temperature of the inner liner, especially the inner liner on the back of the evaporator and the inner liner in the water collection tray area at the bottom of the evaporator during defrosting to improve safety.

[0030] In addition, if Figure 1 and Figure 2As shown, the heat insulating member 60 is attached to the water collecting pan 30 and the first inner liner 201, and the heater 50 is mounted on the heat insulating member 60. In this way, by attaching the designed heat insulating member around the water collecting pan and the first inner liner, the temperature rise of the inner liner, especially the inner liner at the back of the evaporator and the inner liner in the water collecting pan area below the evaporator, can be further effectively suppressed, so that the constituent material of the inner liner more reliably meets the maximum temperature limit of the material, thereby further ensuring safety.

[0031] Hereinafter, an example of a specific structure of the heat insulating member 60 will be described. However, the structure of the heat insulating member 60 is not limited to the following structure, and the structure of the heat insulating member 60 may be any structure as long as the heater 50 and the liner 20 can be reliably insulated.

[0032] Figure 4 2 is a perspective view showing a schematic structure of a heat insulating member provided in a refrigerator according to the present embodiment. Figure 4 As shown, the thermal insulation component 60 includes: a first thermal insulation surface 601 attached along the first inclined surface 301 of the water collection tray 30, a second thermal insulation surface 602 attached along the second inclined surface 302 of the water collection tray 30, and a third thermal insulation surface 603 extending upward from the edges of the first thermal insulation surface 601 and the second thermal insulation surface 602 and attached along the first inner liner 201.

[0033] In this way, by attaching the insulation component along the first inclined surface and the second inclined surface of the water collection tray and the surface of the first inner liner respectively, the temperature rise of the inner liner, especially the inner liner on the back of the evaporator and the inner liner in the water collection tray area under the evaporator can be further effectively suppressed, so that the constituent material of the inner liner can more reliably meet the maximum temperature limit of the material, thereby further ensuring safety.

[0034] In addition, in this embodiment, an opening 604 is formed at the intersection of the first insulation surface 601 and the second insulation surface 602. Thus, defrosted water generated by defrosting the evaporator can flow into the water storage pan through the opening formed at the intersection of the first insulation surface and the second insulation surface.

[0035] In addition, in the present embodiment, the heat insulating component 60 further includes a fixing portion 605. The heat insulating component 60 is fixed by engaging the fixing portion 605 with a protrusion provided on the inner liner 20. In this way, the heat insulating component can be firmly fixed by a simple structure. However, the fixing method of the heat insulating component 60 is not limited thereto, and may be any method such as bonding with an adhesive, screw fastening, welding, etc.

[0036] In addition, in the present embodiment, as the constituent material of the heat insulating member 60, materials such as aluminum can be cited. In this way, by constituting the heat insulating member with aluminum, the heat insulating performance of the heat insulating member can be reliably achieved. However, the constituent material of the heat insulating member 60 is not limited to aluminum, and can also be any material that can achieve a heat insulating effect, such as plastic, resin, etc.

[0037] In addition, in this embodiment, the heater 50 is preferably an iron pipe heater. In this way, by forming the heater with a meandering iron pipe, the heater can be installed in a narrow space to save space.

[0038] In addition, in the present embodiment, the compressor is located at the top of the refrigerator 1. However, the installation position of the compressor is not limited to the top of the refrigerator, and may be the bottom of the refrigerator.

[0039] According to the utility model, a refrigerator can be provided which can reduce the temperature of the inner container during defrosting to improve safety.

[0040] The embodiments of the present invention are described above, but the present invention is not limited to the above embodiments. Those skilled in the art can modify and change the present invention as needed without departing from the essential spirit and scope of the present invention. These modifications and changes all fall within the scope of the present invention.
