Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a drawer-type microwave oven. Background Technology

[0002] As modern families increasingly demand higher performance from kitchen appliances, microwave ovens, as commonly used kitchen heating devices, are gradually becoming a focus of user attention.

[0003] Existing microwave ovens are inconvenient for taking items out and putting them in, making drawer-type microwave ovens a focus of user attention.

[0004] The prior art patent application CN201420532834.2 discloses a drawer-type microwave oven, including: a cooking cavity, a drive device, a drawer, a door, a control panel, and a controller; the door is provided with a hook, the cooking cavity is provided with a slot that cooperates with the hook, and a micro switch is provided in the slot. The hook and the slot can cooperate or separate to make the micro switch conduct or disconnect. The control panel is provided with a locking switch. The controller can control the operation of the drive device according to the instructions of the control panel. When the locking switch is open, the controller cannot receive instructions from the control panel. At this time, if the micro switch is disconnected and / or the drive device is activated, the controller will lock the drive device.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] In existing technologies, the door hook itself lacks elasticity, resulting in: 1) difficulty in opening and closing the door; 2) the door cannot automatically spring back to the closed position, requiring the user to manually push it tight, increasing operational complexity; and 3) the hard collision between the door hook and the furnace body causes abnormal noise between the door and the machine body, which not only reduces user comfort but also increases equipment wear and tear and shortens its service life.

[0046] To solve the above technical problems, such as Figures 1-10 As shown, this embodiment proposes a drawer-type microwave oven 100.

[0047] The drawer-type microwave oven 100 includes:

[0048] Furnace body 1, a slot 71 is provided on the furnace body 1, and a micro switch 72 is provided in the slot 71;

[0049] Drawer assembly 2 is provided on the furnace body 1 in a push-pull manner. The drawer assembly 2 includes a door 21, on which an elastic door hook 61 and an elastic element 62 are provided. One end of the elastic element 62 is connected to the elastic door hook 61, and the other end of the elastic element 62 is connected to the door 21, forming a lever structure.

[0050] The resilient door hook 61 includes:

[0051] The hook part 611, which engages or disengages with the slot 71, can turn the micro switch 72 on or off.

[0052] The rotating hole 612 serves as a pivot point, enabling the elastic door hook 61 to rotate around the door portion 21. The elastic door hook 61 is rotatably connected to the door portion 21 through the rotating hole 612.

[0053] A connecting hole 613 is provided for mounting the elastic element 62, and the connecting hole 613 is located below the rotating hole 612.

[0054] The flexible door hook 61 and the flexible element 62 work together to achieve multiple functions: First, they improve the smoothness of opening and closing the door; second, after the drawer assembly 2 is pulled out, the flexible element 62 pulls the flexible door hook 61 to reset, and the door 21 automatically rebounds, reducing user operation; third, they reduce the impact noise between the door 21 and the furnace body 1, which not only improves user comfort but also avoids mechanical wear caused by hard collisions, reduces equipment wear, and extends service life.

[0055] The connecting hole 613, located below the rotating hole 612, serves multiple purposes: First, the pulling direction of the elastic element 62 forms a reasonable torque with the rotation center (rotating hole 612) of the elastic door hook 61, reducing lateral offset and improving locking stability; Second, the pulling direction of the elastic element 62 is consistent with the pushing and pulling direction of the drawer assembly 2, reducing operating resistance and further improving operational smoothness; Third, the installation path of the elastic element 62 is shorter, reducing the assembly difficulty of the elastic element 62.

[0056] In summary, this embodiment proposes a drawer-type microwave oven 100, in which the elastic door hook 61 and the elastic element 62 cooperate, and the connecting hole 613 is located below the rotating hole 612, which serves multiple purposes: First, it improves the smoothness of opening and closing the door; second, after the drawer assembly 2 is pulled out, the elastic element 62 pulls the elastic door hook 61 to reset, and the door 21 automatically rebounds, reducing user operation; third, it reduces the impact noise between the door 21 and the oven body 1, which not only improves user comfort but also avoids mechanical wear caused by hard collisions, reduces equipment wear, and extends lifespan; fourth, the pulling direction of the elastic element 62 and the rotation center (rotating hole 612) of the elastic door hook 61 form a reasonable torque, reducing lateral offset and improving locking stability; fifth, the installation path of the elastic element 62 is shorter, reducing the assembly difficulty of the elastic element 62.

[0057] Specifically, the hook portion 611 is located on the side away from the door portion 21, and the rotating hole 612 and the connecting hole 613 are located on the side closer to the door portion 21.

[0058] Specifically, such as Figure 7 As shown, the drawer assembly 2 also includes a mounting portion and a support portion 23. The mounting portion is capable of mounting the heated object, and the support portion 23 is capable of supporting the mounting portion.

[0059] As a preferred example of this application, such as Figure 5 and Figure 6 As shown, a first reinforcing protrusion 614 is provided on the elastic door hook 61, extending upwards towards the elastic door hook 61. The rotating hole 612 is provided on the first reinforcing protrusion 614. This arrangement improves the structural strength at the rotating hole 612, thereby improving the rotational stability of the elastic door hook 61.

[0060] As a preferred example of this application, such as Figure 5 and Figure 6 As shown, a second reinforcing protrusion 615 is provided on the elastic door hook 61, extending downwards from the elastic door hook 61. The rotating hole 612 is provided on the second reinforcing protrusion 615. This arrangement improves the structural strength at the connecting hole 613, thereby enhancing the connection stability between the elastic door hook 61 and the elastic element 62.

[0061] As a preferred example of this application, such as Figure 5 As shown, a third reinforcing protrusion 616 is provided on the first reinforcing protrusion 614. The third reinforcing protrusion 616 extends in a direction away from the center of the door portion 21, and the rotating hole 612 passes through the third reinforcing protrusion 616. This arrangement further improves the structural strength at the rotating hole 612, thereby further improving the rotational stability of the elastic door hook 61.

[0062] As a preferred example of this application, such as Figure 6 As shown, a fourth reinforcing protrusion 617 is provided on the first reinforcing protrusion 614. The fourth reinforcing protrusion 617 extends toward the center of the door portion 21, and the rotating hole 612 passes through the fourth reinforcing protrusion 617. This arrangement further improves the structural strength at the rotating hole 612, thereby further improving the rotational stability of the elastic door hook 61.

[0063] As a preferred example of this application, such as Figure 6 As shown, the third reinforcing protrusion 616 and the fourth reinforcing protrusion 617 are symmetrically arranged on the left and right sides of the first reinforcing protrusion 614. This arrangement improves the balance of structural strength at the rotating hole 612, thereby further improving the rotational balance and stability of the elastic door hook 61.

[0064] As a preferred example of this application, such as Figure 4 As shown, a connector 70 is installed on the furnace body 1, a slot 71 is provided on the connector 70, and a micro switch 72 is installed on the connector 70, as shown. Figure 4 and Figure 8 As shown, a beveled portion 73 is provided on the connector 70, such as... Figure 4 As shown, the slot 71 is located on the rear side of the inclined surface 73.

[0065] The slot 71, micro switch 72, and beveled surface 73 are integrated onto a single connector 70, avoiding the need for multiple components to be installed separately on the furnace body 1, reducing assembly complexity, and improving installation efficiency. The beveled surface 73 serves as a guide structure for the insertion of the elastic door hook 61 into the slot 71, optimizing operational smoothness. The beveled surface 73 also prevents hard collisions between the elastic door hook 61 and the edge of the slot 71, reducing noise and extending component life.

[0066] Specifically, the elastic element 62 is not limited in its specific form.

[0067] As a preferred example of this application, such as Figure 4 As shown, the elastic element 62 is a spring. The spring has a fast response speed and smooth operation. The elastic potential energy of the spring is released quickly, and the elastic door hook 61 can be instantly reset, improving the smoothness of the push-pull drawer assembly 2. The spring can absorb the impact force between the elastic door hook 61 and the slot 71, reducing abnormal noise and wear. In addition, the spring has a simple structure and low cost.

[0068] As a preferred example of this application, such as Figure 9 As shown, the furnace body 1 includes an inner liner 12, such as Figure 10As shown, a heating cavity 3 is formed inside the inner liner 12, and a microwave heating assembly 4 is installed on the furnace body 1. The microwave heating assembly 4 is used to supply microwaves to the heating cavity 3, such as... Figure 9 and Figure 10 As shown, the microwave heating component 4 is disposed on the top wall 121 of the inner liner 12.

[0069] This design has several advantages: First, it allows microwaves to cover the food inside the heating cavity 3 more evenly, improving the uniformity of food heating; second, the structure is reasonably laid out, with the microwave heating component 4 placed on the top wall 121, which does not occupy the side or rear wall space of the inner liner 12, making the internal space of the heating cavity 3 more regular, which is conducive to the placement of food and the cooking process; third, the position of the top wall 121 is relatively open, which facilitates the installation and disassembly of the microwave heating component 4.

[0070] As a preferred example of this application, such as Figure 9 As shown, a convection component 5 is provided on the furnace body 1, and the convection component 5 is used to form circulating air in the heating chamber 3.

[0071] In this application, the convection component 5 and the microwave heating component 4 work together to achieve a dual heating method of microwave heating and convection heating. Microwave heating can quickly penetrate food, causing the interior of the food to heat up rapidly, while convection heating can create a caramelized crust on the surface of the food, while ensuring uniform heating inside the food. This synergistic effect greatly improves cooking efficiency and cooking quality.

[0072] The drawer-type microwave oven 100 also includes other related components. Since the specific structure and assembly relationship of these components are existing technologies, they will not be described in detail here.

[0073] This embodiment proposes a drawer-type microwave oven 100, in which a flexible door hook 61 and a flexible element 62 cooperate, and a connecting hole 613 is located below the rotating hole 612, serving multiple functions: First, it improves the smoothness of opening and closing the door; second, after the drawer assembly 2 is pulled out, the flexible element 62 pulls the flexible door hook 61 to reset, and the door 21 automatically rebounds, reducing user operation; third, it reduces the impact noise between the door 21 and the oven body 1, which not only improves user comfort but also avoids mechanical wear caused by hard collisions, reduces equipment wear, and extends lifespan; fourth, the pulling direction of the flexible element 62 and the rotation center (rotating hole 612) of the flexible door hook 61 form a reasonable torque, reducing lateral offset and improving locking stability; fifth, the installation path of the flexible element 62 is shorter, reducing the assembly difficulty of the flexible element 62.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
