The embodiment of the utility model provides an ultra-thin type thawing apparatus and device integration in method of refrigerator for solve among the prior art with thawing apparatus integration lead to the space of storage to diminish or increase the volume of refrigerator, have technical problem such as cold-hot separation and heat dissipation channel on the refrigerator box.

Fig. 1 and 2 are a front view and an oblique view of a refrigerator according to an embodiment of the present invention. Referring to fig. 1 and 2, the refrigerator 1 has a thawing device 11, and the thawing device 11 is integrated on a refrigerator door 10 of the refrigerator 1.

Preferably, the refrigerator door 10 of the integrated defrosting device 11 is a refrigeration door. Because the margin of the foaming layer in the refrigerator liner 16 (shown in fig. 4) on the refrigerating door body is large, the space of the foaming layer is easy to utilize, the temperature difference is small compared with that of freezing, and the influence of heat generated in the unfreezing process on the temperature in the refrigerating chamber of the refrigerator 1 is small. The refrigerator door 10 is used for isolating the internal space of the refrigerator 1 from the external environment, and plays a role in maintaining the internal temperature of the refrigerator 1. The refrigerator door 10 according to the present invention will be further described with reference to fig. 3 to 5.

The refrigerator door body 10 is provided with:

the defrosting device 11 is embedded in the refrigerator door body 10, and the defrosting device 11 is separated from the inside of the refrigerator 1 by a heat insulation bubble layer. (the cold area and the hot area are separated by a heat insulation layer to avoid the cold loss of the refrigerator 1, which causes poor refrigeration effect and unnecessary energy consumption.)

The heat dissipation holes 12 are disposed on the frame of the refrigerator door 10 corresponding to the thawing device 11, and are used for discharging heat generated by the microwave generating device (magnetron) during operation to the outside of the refrigerator 1. The scope of protection is not limited thereto as long as the roles of the heat dissipation holes 12 are the same.

The thawing device door 13 is openably and closably connected to the lower end of the refrigerator door 10 by a hinge, and is made of a metal material for shielding electromagnetic waves radiated from the thawing device 11 during thawing. In some embodiments, the opening limit angle is 24 ° -30 °. Here, the opening limit angle is set to 24 ° to 30 ° because a user can take out the food shelf 1122 for washing in this angle range, and too large an opening angle causes an increase in the force applied to the hinge. The opening limit angle of the door body 13 of the thawing device is only required to be within an angle range that the food material can not fall within the range as long as the food material can be placed and taken out conveniently by a user, and the protection range is not limited to the range. The opening mode of the door body 13 of the thawing device can be a push-spring mode or a pull-handle mode, and the opening mode of the door body 13 of the thawing device is not limited to this as long as normal opening and locking can be ensured.

And the safety switch 14 is arranged on the refrigerator door body 10, is made of a metal proximity switch and is used for sensing the opening and closing state of the unfreezing device door body 13 made of metal. When the safety switch 14 senses that the door 13 of the thawing device made of metal is in an open state, even if a user sends a thawing command to the thawing device 11, for example, the thawing command is controlled by a button on a panel of a refrigerator, the thawing device 11 does not work; when the safety switch 14 senses that the door body 13 of the thawing device made of metal is in a closed state, an instruction sent by a user to the thawing device 11 is enabled, so that the thawing device 11 can work. This can avoid electromagnetic leakage caused when thawing is performed in a state where the thawing apparatus door 13 is not closed.

The thawing apparatus 11 according to the present invention will be further explained with reference to fig. 5.

The thawing device 11 comprises a thawing device fixing part 111 and a thawing device movable part 112. The thawing device fixing portion 111 is fixed to the refrigerator door 10, and some parts of the thawing device fixing portion 111 may be integrally formed with the thawing device door 13. The thawing device movable unit 112 may be placed in the thawing device fixing unit 111, or may be detached from the thawing device fixing unit 111 to perform an operation such as cleaning.

The interior 1111 is for holding a food rack 1122. Here, the forward opening means an opening facing a user, so that the user can easily put the food shelf 1122 into the inner cavity 1111 after opening the thawing apparatus door 13. The thickness of the cavity 21 is preferably between 120mm and 100mm to avoid taking up too much refrigerator volume; the material is preferably 304 stainless steel, followed by a precoat plate.

The dynamic mirror 1112 is a metal mirror with 1 rotational degree of freedom, and is disposed on the inner wall of the inner cavity 1111, and is configured to change the electromagnetic wave direction and avoid a thawing blind spot. The dynamic reflector 1112 is detachably mounted on the inner cavity through a rotating shaft, is driven by a motor to rotate at a constant speed in a reciprocating manner, and when necessary for maintenance, the dynamic reflector 1122 can be detached from the thawing apparatus 11. Since the thawing means 11 is integrated with the refrigerator door 10, the size of the inner cavity 11 in the thickness direction of the refrigerator door 10 is relatively narrow, and thus if it is desired to thaw the food material uniformly, it is necessary to make the microwave distribution uniform in the direction parallel to the refrigerator door 10 when thawing the food material. The dynamic mirror 1112 may be made of a non-toxic and high-gloss metal with stable physical and chemical properties, which is beneficial for the microwave to be reflected inside the inner cavity 1111, so that the distribution path of the microwave emitted from the dynamic mirror 1112 is more uniform.

The emitting module 1113 is preferably made of a small magnetron with power preferably within 400w because the device is only used for unfreezing and unfrozen food and food materials have small volume. When receiving an instruction of thawing, microwaves for thawing the food material can be emitted downward, and the reflection angle of the microwaves can be adjusted by the dynamic reflector 1112, so that the thawed food material is uniformly heated.

The thawing device movable portion 112 includes:

an outer cavity 1121, made of metal (preferably 304 stainless steel) for receiving a food shelf 1122, the outer cavity 1121 capable of being received in the inner cavity 1111. The benefit of this arrangement is that a reliable faraday cage is formed, preventing microwave leakage.

And a food shelf 1122 for storing food and food materials to be thawed. Because the food shelves 1122 are in direct contact with food and food materials, the food shelves 1122 are kept clean so as not to contaminate the food or food materials. The user can take the food shelf 1122 out of the outer cavity 1121 and wash it, and the thawing apparatus movable part 112 is designed to be the metal outer cavity 1121 nested with the food shelf 1122 and placed in the inner cavity 1111, so that the benefits of the structure 1122 are: the heating device can ensure that the unfreezing device 11 forms a reliable Faraday cage for the food and food heating part, and is convenient to disassemble and clean. The food shelf 1122 can be placed in the outer cavity 1121. In some embodiments, the food shelves 1122 are made of engineering plastic (preferably transparent PP), and the food shelves 1122 are made of microwave transparent material, but the scope of protection is not limited thereto.

When a user needs to quickly thaw food, the door 13 of the thawing apparatus needs to be opened first, and then the food and the food material are put into the food shelf 1122, and the door 13 of the thawing apparatus needs to be closed. The weight of the food product is then set, for example controlled by a button on the refrigerator panel (not shown in the figures) or the like, for calculating the thawing time, or the running time is directly set and the thawing means 11 is started. After thawing, the controller on the main control panel 15 controls the speaker or the indicator light (not shown in the figure) to emit sound and light prompts. In some embodiments, an aspect of the sound such as a general "ding" sound of a microwave oven, or playing a special music to alert the end of the thawing process. The aspect of the light is that the internal illumination lamp is off indicating the end of the thawing process.
