The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figure 1-4 As shown, a microwave defrosting device installed in a cabinet includes a microwave generating component 2, a safety protection component, and a replacement cabinet door component 4 installed in the cabinet 1. The top of the cabinet 1 is provided with a mounting hole 1a.

[0033] The microwave generating assembly 2 includes a protective shell 21 and a microwave generator 22. The protective shell 21 is wrapped around the microwave generator 22, and the protective shell 21 has an installation port 21a at the microwave emitting end of the microwave generator 22.

[0034] The microwave generator 22 is connected to the outer top of the housing 1 through the protective shell 21, and the microwave emitting end extends into the housing 1 after passing through the mounting hole 1a;

[0035] The safety protection components include flange 3 and protective seals (not shown in the figure);

[0036] A flange 3 is provided between the mounting port 21a and the mounting hole 1a of the protective housing 21, and protective seals are provided between the flange 3 and the protective housing 21 and between the flange 3 and the mounting hole 1a.

[0037] The replacement cabinet door assembly 4 includes a protective cabinet door 41, a sealing ring 42, and a hinge (not shown in the figure). The protective cabinet door 41 is rotatably hinged to the cabinet body 1 via the hinge, and a sealing ring 42 is provided around the outer perimeter of the protective cabinet door 41 and the cabinet door of the cabinet body 1.

[0038] In this embodiment, the housing 1 is the housing 1 of a cold storage or freezer, etc. A microwave defrosting device is installed on the existing housing 1 of the cold storage or freezer. The installation steps are as follows:

[0039] Step 1: Cut a circular mounting hole 1a with a diameter of 52mm on the top of the housing 1;

[0040] Step 2: Based on the dimensions of the box 1, connect the microwave generator 22 to the upper outer side of the box 1 through the protective shell 21, and extend its microwave emitting end from the mounting hole 1a into the box 1, ensuring that the microwave emitting port corresponds to the item to be thawed inside the box 1.

[0041] Step 3: Install flange 3 and sealing mesh at the connection between the microwave transmitting end of microwave generator 22 and the mounting hole 1a of housing 1, so that they fit tightly to prevent microwave leakage.

[0042] Step 4: Remove the original cabinet door of box 1, install the designed protective cabinet door 41 on box 1 using special hinges, adjust the position of the protective cabinet door 41, and ensure that the sealing ring 42 is in close contact with the door frame of box 1.

[0043] This allows the microwave defrosting device to be installed on cold storage or freezers. Compared to existing technologies that use separate microwave defrosting equipment, users do not need to purchase a complete set of microwave defrosting equipment. They can simply add this device to the existing cabinet 1 to achieve the microwave defrosting function, which greatly reduces the equipment purchase cost.

[0044] Furthermore, by replacing the cabinet door assembly 4 with a leak-proof and sealing structure, the installation of the microwave defrosting device is ensured to be safe and reliable, effectively preventing microwave leakage.

[0045] In this embodiment, when the protective cabinet door 41 is closed, the sealing ring 42 is in close contact with the door of the cabinet 1, forming a good electromagnetic seal, which further prevents microwaves from leaking from the gap between the protective cabinet door 41 and the cabinet 1.

[0046] In this embodiment, the microwave frequency range generated by the microwave generator 22 can be customized and adjusted according to different thawing needs. In this embodiment, a 500W (direct start) microwave generator 22 is used, which can generate microwaves with a frequency of 2450 MHz.

[0047] Furthermore, such as Figure 1 , 2 As shown, in order to concentrate more microwaves on the thawing object and improve thawing efficiency and uniformity, the microwave generating component 2 also includes at least two layers of reflective plates 23 disposed inside the housing 1, which are used to change the microwave reflection path.

[0048] In this embodiment, the reflector 23 can be adjusted in its installation position and tilt angle within the housing 1 as needed.

[0049] In this embodiment, the combination of the position of the reflector 23 and the mounting hole 1a allows the microwave emitting end to be aligned with the object to be thawed, and more microwaves are reflected and concentrated on the object to be thawed, achieving rapid and uniform thawing, avoiding damage to the object due to uneven local heating, and ensuring the quality of the object.

[0050] Furthermore, such as Figure 2 As shown, in order to achieve a reliable connection between the reflector 23 and the interior of the housing 1, the reflector 23 is provided with a bent structure 23a that connects to the inner wall of the housing 1.

[0051] The reflector 23 is screwed or welded to the inner wall of the box 1 via a bending structure 23a.

[0052] Furthermore, the safety protection component also includes a microwave detection sensor (not shown in the figure), which is used to detect whether there is microwave leakage at the mounting hole 1a and the cabinet door. The microwave detection sensor is electrically connected to the microwave generator 22.

[0053] In this embodiment, a microwave detection sensor automatically detects whether there is microwave leakage at the mounting hole 1a or cabinet door, and automatically controls the microwave generator 22 to work or stop, thereby accurately and quickly detecting leakage and greatly ensuring the safety of operators.

[0054] Furthermore, such as Figure 1 , 4 As shown, in order to improve the microwave shielding performance and heat preservation performance of the protective cabinet door 41, the protective cabinet door 41 includes a double-layer metal plate 41a and a microwave absorbing material 41b disposed between the double-layer metal plate 41a; the microwave absorbing material 41b is polyurethane material.

[0055] Furthermore, in order to ensure good conductivity and form a continuous electrical connection between the protective cabinet door 41 and the cabinet body 1, which helps to enhance the shielding effect against microwaves, the hinge is made of metal.

[0056] Furthermore, in order to meet the needs of different cold storage, freezer and other cabinet structures, the protective cabinet door 41 is an integrated single cabinet door or an upper and lower double cabinet door structure.

[0057] Furthermore, in order to improve the electromagnetic shielding effect and effectively prevent microwave leakage, the sealing ring 42 is a metal wire mesh sealing ring 42.

[0058] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
