Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, and more specifically, to a portable microwave oven. Background Art
[0002] With the acceleration of the pace of life, people's lifestyles have become more diverse. Especially for groups such as travelers and outdoor explorers, they need to quickly heat food in outdoor environments. As a common household kitchen appliance, a microwave oven is usually large in size, heavy in weight and inconvenient to move, which greatly limits its flexibility and portability in use. Therefore, a portable microwave oven has emerged as the times require.
[0003] For the convenience of interaction, the keys of a portable microwave oven are usually arranged on the top plate. When a user sets parameters, the keys will be pressed downwards and a gap will be generated between the keys and the top plate. At this time, if external water droplets enter from the gap and drip onto the internal circuit board, serious safety hazards will occur.
[0004] In view of this, the present utility model is specifically proposed. Summary of the Utility Model
[0005] The problem solved by the present utility model is that the waterproof effect of the existing microwave oven is poor, and there are certain safety hazards when used in outdoor scenarios.
[0006] To solve the above problems, the present utility model provides a portable microwave oven, which includes a top cover. The top cover is provided with an interaction component. The interaction component includes an interaction part and a circuit board. The interaction part protrudes partially from the top cover. The circuit board is located below the top cover. The interaction part can selectively contact the circuit board, and a waterproof part is arranged between the interaction part and the circuit board.
[0007] This setting can ensure that the gap between the interaction part and the top cover when the user presses the interaction part is blocked by the waterproof part, preventing external water vapor from directly dripping down from the edge of the interaction part onto the circuit board, meeting the use requirements in outdoor environments and having strong reliability.
[0008] Preferably, an assembly post is arranged on the lower side of the top cover. A fixing seat is arranged on the waterproof part. One side of the fixing seat abuts against the circuit board. The fixing seat is partially recessed downward to form an installation groove. The assembly post is embedded in the installation groove. The assembly post, the fixing seat and the circuit board are assembled by a second fastener. This setting can strengthen the assembly post by using the fixing seat, and at the same time, the fixing seat also increases the contact area with the circuit board, with reliable and firm connection and high assembly efficiency.
[0009] Preferably, the waterproof member includes a bottom plate, a folding edge is provided at the outer edge of the bottom plate, an avoidance hole is provided on the bottom plate, an annular rib is provided around the avoidance hole, the fixing seats are respectively provided on both sides of the bottom plate, and there is a height difference between the lowest point of the fixing seat and the bottom plate.
[0010] Even if external water vapor enters the bottom plate of the waterproof member, the folding edge and the annular rib can restrict the flow of the water vapor so that it enters the installation groove, and even if it flows out, it is on both sides of the circuit board, with good safety; in addition, there is a height difference between the fixing seat and the bottom plate, which can form an avoidance for the circuit board and make the overall structure compact.
[0011] Preferably, the folding edges are in the same plane and are in contact with the lower surface of the top cover, and the folding edges are located on the outer peripheral side of the interaction member. This setting can ensure that all the water entering the interaction member is collected by the waterproof member, and the waterproof effect is good.
[0012] Preferably, the top cover is provided with an installation opening, one end of the interaction member passes through the installation opening, and the other end of the interaction member is provided with an annular folding edge, and the diameter of the annular folding edge is D 1 , and the diameter of the installation opening is D 2 , where D 1 > D 2 is set. This setting can ensure that the interaction member is limited by the top cover and the waterproof member, with a simple structure and convenient for production and processing.
[0013] Preferably, the interaction member is provided with a connecting rod, and a spring is sleeved outside the connecting rod, and one end of the spring is in contact with the waterproof member. This setting can ensure that the interaction member is always in close contact with the top cover when not being pressed, and the waterproof effect is good.
[0014] Preferably, the top cover is provided with a groove, a telescopic handle is arranged in the groove, the groove includes an assembly bottom plate, assembly columns are arranged on the upper surface of the assembly bottom plate, the telescopic handle is provided with a fitting sleeve, and the fitting sleeve is sleeved outside the assembly column and the two are connected by a first fastener.
[0015] Through the socket connection of the fitting sleeve and the assembly column, the connection hole of the assembly column is located away from the assembly bottom plate and at a higher position, so that even if water enters the groove, it will not enter the interior from the screw hole; at the same time, it plays a pre-positioning role during the assembly process, avoiding misassembly and improving the convenience of assembly; in addition, it further increases the contact area between the handle slide rail and the groove, which is beneficial to improving the force distribution between the two.
[0016] Preferably, the first fastener is located above the assembly bottom plate. This setting can avoid punching holes in the assembly bottom plate, so that the assembly bottom plate is always in a closed state and will not leak water into the interior at all.
[0017] Preferably, the telescopic handle includes a handle member and a handle slide rail. The handle member is connected to the handle slide rail in such a way that it can move relative to the handle slide rail in the vertical direction, and the fitting sleeve is arranged on the handle slide rail. This setting improves the convenience and practicality of the portable microwave oven. When the telescopic handle is not in use, the handle structure will not protrude outside the microwave oven, avoiding collisions between the telescopic handle and external objects and saving a certain amount of space.
[0018] Preferably, the handle member has a sliding arm corresponding to the handle slide rail. The sliding arm can move along the handle slide rail in the vertical direction. A slideway cavity is arranged inside the sliding arm. At least the upper end of the handle slide rail is arranged inside the slideway cavity. An inward flanging is arranged at the lowermost end of the sliding arm, and an outward flanging is arranged at the uppermost end of the handle slide rail. The inward flanging can abut against the outward flanging.
[0019] This setting enables the sliding arm to be sleeved outside the handle slide rail, which is beneficial to improving the smoothness of the up and down movement of the sliding arm and also beneficial to improving the structural reliability of the abutment between the inward flanging and the outward flanging. At the same time, the handle member can shield the handle slide rail through the sliding arm, as much as possible to prevent users from seeing internal structural components such as the handle slide rail, so as to improve the aesthetics of the microwave oven near the handle structure.
[0020] Compared with the prior art, the portable microwave oven of the present invention has the following beneficial effects: 1) By providing a waterproof member, it can prevent external water vapor from directly dripping down from the edge of the interaction member to the circuit board, enabling the microwave oven to have a certain waterproof performance and meeting the use requirements in outdoor environments; 2) Through the socket connection between the fitting sleeve and the fitting post, the connection hole of the fitting post is located far from the fitting bottom plate and at a relatively high position, so that even if water enters the groove, it will not enter the interior through the screw hole, and the safety is good; 3) The structure is compact and convenient for production and processing.

[0039] Embodiment 2
[0040] Since the telescopic handle 2 of the portable microwave oven is provided on the top cover 1, in bad weather such as rain outdoors, a certain amount of water will accumulate in the groove 11 for accommodating the telescopic handle 2. Once it enters the interior of the portable microwave oven, there will be certain potential safety hazards. Therefore, on the basis of Embodiment 1, the applicant proposes the following technical solution:
[0041] As Figures 5-7 shown, the telescopic handle 2 includes a handle member 22 and a handle slide rail 23. The handle member 22 is connected to the handle slide rail 23 in a manner that can move relative to the handle slide rail 23 in the vertical direction. The groove 11 has an assembly cavity 111 corresponding to the handle slide rail 23. An assembly bottom plate 112 is provided at the bottom of the assembly cavity 111, and an assembly post 113 is provided on the upper surface of the assembly bottom plate 112. The handle slide rail 23 is provided with a fitting sleeve 232. The fitting sleeve 232 is sleeved outside the assembly post 113 and the two are connected by a first fastener 24.
[0042] By sleeving the fitting sleeve 232 with the assembly post 113, it is possible to avoid drilling holes in the assembly bottom plate 112, so that the assembly bottom plate 112 is always in a closed state and will not leak water into the interior. At the same time, it plays a role of pre-positioning during the assembly process, avoiding misassembly and improving the convenience of assembly; in addition, it further increases the contact area between the handle slide rail 23 and the groove 11, which is beneficial to improving the force distribution between the two.
[0043] When it is necessary to move the portable microwave oven, the user inserts a finger into the groove 11 and applies an upward force to the handle member 22, so that the handle member 22 extends upward. By firmly holding the handle member 22, the microwave oven can be lifted (as Figure 5 shown); when the handle member 22 is released, the handle member 22 will slide down along the handle slide rail 23 into the groove 11 under the action of its own gravity (as Figure 7 shown), which improves the convenience and practicality of the microwave oven. When the telescopic handle 2 is not in use, the handle structure will not protrude outside the microwave oven, avoiding collisions between the telescopic handle 2 and external objects, and also saving a certain amount of space.
[0044] Preferably, when the handle member 22 slides down along the handle slide rail 23 into the groove 11, or in other words, when the telescopic handle 2 is in the retracted state, the upper surface of the telescopic handle 2 is flush with the top cover 1. Thus, after the telescopic handle 2 is retracted, the telescopic handle 2 does not protrude from the microwave oven, and a relatively flat upper surface can be formed on the upper side of the microwave oven, which is beneficial to improving the aesthetic performance of the microwave oven and also facilitates the user to temporarily place items.
[0045] Regarding the setting between the handle member 22 and the handle slide rail 23, the handle member 22 has a slide arm 221 corresponding to the handle slide rail 23. The slide arm 221 can move vertically along the handle slide rail 23. As the slide arm 221 moves upward, the lower end of the slide arm 221 can abut and be limited by the upper end of the handle slide rail 23. Thus, after the handle member 22 moves upward along the handle slide rail 23 to a certain height, it will abut against the handle slide rail 23. At this time, when a person pulls up the handle member 22 upward, the entire microwave oven can be lifted, which is convenient for the user's operation convenience.
[0046] Preferably, a slideway cavity 223 is provided inside the slide arm 221. At least the upper end of the handle slide rail 23 is arranged inside the slideway cavity 223. An inward flanging 222 is provided at the lowermost end of the slide arm 221, and an outward flanging 231 is provided at the uppermost end of the handle slide rail 23. The inward flanging 222 can abut against the outward flanging 231, so that the slide arm 221 can be sleeved outside the handle slide rail 23, which is beneficial to improving the smoothness of the vertical movement of the slide arm 221 and also beneficial to improving the structural reliability of the abutment between the inward flanging 222 and the outward flanging 231. At the same time, the handle member 22 can shield the handle slide rail 23 through the slide arm 221, and as much as possible prevent the user from seeing internal structural parts such as the handle slide rail 23, so as to improve the aesthetics of the microwave oven near the handle structure.
[0047] In order to facilitate the telescopic operation of the telescopic handle 2, in the projection on the vertical direction, the minimum projected area of the assembly cavity 111 ≥ the maximum projected area of the slide arm 221. Thus, when the slide arm 221 moves up and down along the handle slide rail 23, the slide arm 221 will not have spatial interference with the side wall of the assembly cavity 111, so as to ensure the normal telescoping of the telescopic handle 2.
[0048] The handle member 22 and the handle slide rail 23 are preferably both hollow members. On the one hand, it is convenient for production and manufacturing, reducing costs. On the other hand, it is beneficial to reduce the weight of related components, facilitating the reduction of the weight of the entire microwave oven and making it more portable. On this basis, the slideway cavity 223 of the handle member 22 can be regarded as a part of its hollow structure and does not need to be set separately. Correspondingly, the hollow cavity of the handle member 22 communicates with the hollow cavity of the handle slide rail 23; the fitting sleeve 232 can also be arranged inside the hollow cavity of the handle slide rail 23. At the same time, a handle cover 21 is arranged on the top of the handle member 22, and the handle cover 21 is connected to the handle member 22 in a detachable manner. For example, the handle cover 21 is snap-connected to the handle member 22. On the one hand, it shields the internal hollow structure of the handle member 22 and can also improve the aesthetics of the upper surface of the telescopic handle 2. On the other hand, when it is necessary to disassemble and assemble the telescopic handle 2, after removing the handle cover 21, the fastener 6 located in the hollow cavity of the handle slide rail 23 can be directly disassembled and assembled, so that the entire telescopic handle 2 can be disassembled, assembled and maintained simply and conveniently.
[0049] In the present utility model, for any microwave oven, it may include the relevant structures and assembly relationships provided in this embodiment to achieve the portable function of the microwave oven. In addition, on this basis, the microwave oven further includes a housing 4, a door assembly 5, a magnetron, a heating cavity and other conventional components of the microwave oven. For example, the door assembly 5 is arranged on the front side of the housing 4, etc. Since they are all prior arts, they will not be elaborated here.
[0050] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
