Description

Technical Field

[0001] This invention belongs to the field of microwave baking technology, specifically relating to a microwave baking device and a method for adjusting the microwave baking device. Background Technology

[0002] Microwave radiation is a form of physical pollution that is not easily detected by people. Therefore, controlling microwave leakage in microwave products is of paramount importance in related designs. Whether it is the flow channel in the door design or the metal casing of the microwave generator, the purpose is to prevent microwave leakage and avoid harm to the human body during use.

[0003] The main outlet for microwave leakage is the door itself. The door design incorporates yoke channels in the door frame and a mesh plate with densely packed small holes to effectively control microwave leakage. However, some hidden issues remain at the fit between the door and the inner liner, potentially leading to leakage. In previous microwave products, whether side-opening or bottom-opening, the fit between the door and the inner liner frame, controlled by the hinges, depended on the dimensional tolerances of relevant parts and the installation of the sealing strips. In such cases, errors in tolerances and sealing strips can result in a loose fit, making it difficult to prevent microwave leakage.

[0004] Accordingly, there is a need in the art for a new microwave baking device and a method for adjusting the microwave baking device to solve the problem in the prior art where microwave products are prone to microwave leakage due to poor fit between the door and the inner liner caused by factors such as dimensional tolerances.

[0048] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the specification describes the invention using six second through holes and six second threaded holes as an example, the invention can obviously employ other similar means, such as two or four second through holes and four second threaded holes, as long as the number of second through holes and two threaded holes facilitates adjustment of the hinge assembly's position.

[0049] It should be noted that in the description of this invention, terms such as "inner side" indicating direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "equipped," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, etc. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] like Figure 1-7 As shown, Figure 1 This is a structural diagram of one embodiment of the microwave baking equipment of the present invention. Since the present invention addresses the problem of microwave leakage in microwave products due to poor fit between the door and inner cavity caused by dimensional tolerances and other factors, therefore… Figure 1Only relevant partial structures are shown. This invention provides a microwave baking apparatus, which can be a microwave oven, microwave oven, or similar device. Figure 1-5 As shown, the microwave baking equipment includes a door 1, a side wall assembly 2, a hinge assembly 3, and an adjusting component. One end of the hinge assembly 3 is fixedly connected to the door 1. The hinge assembly 3 includes a hinge body 34 and an adjustable bracket 35 fixedly connected. The hinge body 34 is fixedly connected to the door 1. The side wall assembly 2 includes a detachable and fixedly connected side plate 24 and a decorative plate 25. The decorative plate 25, the adjustable bracket 35, the side plate 24, and the hinge body 34 are arranged sequentially. The hinge assembly 3 is slidably disposed within a hinge body groove 37 on the side wall assembly 2, and the hinge body groove 37 is fixedly disposed on the inner side of the side wall assembly 2.

[0052] The decorative panel 25 is provided with a first through hole 21, a second through hole 22, and a third through hole 23. The first through hole 21 and the second through hole 22 are round holes, and the third through hole 23 is an oblong hole. The center line of the third through hole 23 is parallel to the line connecting the centers of the first through hole 21 and the second through hole 22, so that the hinge assembly 3 can be translated as a whole along the direction of a predetermined center line of the third through hole 23. In this embodiment, the center line of the third through hole 23 refers to the virtual line connecting the longest two ends of the third through hole 23. Multiple second through holes 22 are provided, preferably, such as... Figure 5 As shown, there are six second through holes 22, which are equally spaced on both sides of the first through hole 21, such that the distance between any two adjacent second through holes 22 and the distance between any two adjacent second through holes 22 and the first through hole 21 are the same. Figure 3 As shown, preferably, the number of third through holes 23 is two.

[0053] At the other end of the hinge assembly 3, multiple mounting structures are provided, each consisting of a first threaded hole 31, a second threaded hole 32, and a third threaded hole 33. For example... Figure 3 As shown, the adjustable bracket 35 is provided with a first threaded hole 31 and a second threaded hole 32, and also has a fourth through hole 36 that matches the third through hole 23. The fourth through hole 36 is a round hole. Multiple second threaded holes 32 are provided; preferably, there are six second threaded holes 32. The six second threaded holes 32 are equally spaced on both sides of the first threaded hole 31, so that the distance between any two adjacent second threaded holes 32 and the distance between adjacent second threaded holes 32 and the first threaded hole 31 are the same.

[0054] A fifth through hole 26 matching the third through hole 23 is provided on the side plate 24. The fifth through hole 26 is an elongated hole. A clearance hole 27 is also provided on the side plate 24. The clearance hole 27 is an elongated hole.

[0055] The hinge body 34 is provided with a third threaded hole 33 that matches the third through hole 23. There are two third threaded holes 33.

[0056] The distance between the first threaded hole 31 and the second threaded hole 32 is not equal to the distance between the first through hole 21 and the second through hole 22. This means the distance between the first threaded hole 31 and the adjacent second threaded hole 32 is not equal to the distance between the first through hole 21 and the adjacent second through hole 22. Alternatively, the distance between the first threaded hole 31 and the second threaded hole 32 can be greater than the distance between the first through hole 21 and the second through hole 22, ultimately forming a... Figure 5 The misalignment scheme is shown. The adjusting components include a first bolt 4 and a second bolt 5. The first bolt 4 passes through the first through hole 21 and is connected to the first threaded hole 31. The second bolt 5 passes through the third through hole 23 and is connected to the third threaded hole 33 to adjust and fix the position of the hinge assembly.

[0057] The above content describes the microwave baking apparatus of the present invention. Next, the method for adjusting the microwave baking apparatus of the present invention will be described.

[0058] like Figure 8 As shown, the control method of the present invention includes the following steps:

[0059] S1. Measure the gap between the opening / closing door 1 and the side wall assembly 2.

[0060] During the design and manufacturing of the hinged door 1, due to factors such as dimensional tolerances of related parts, it is difficult to ensure that the manufactured hinged door 1 and the side wall assembly 2 achieve a perfectly appropriate fit. Therefore, there may be cases where the gap between the hinged door 1 and the side wall assembly 2 is too large or too small. When the gap between the hinged door 1 and the side wall assembly 2 is too large, it will be difficult to prevent microwave leakage; while when the gap is too small, it will affect the normal opening of the hinged door 1. In this invention, the gap between the hinged door 1 and the side wall assembly 2 is measured first, so that the hinged door 1 can be adjusted according to the actual gap.

[0061] S2. When the gap size does not meet the preset value, loosen the second bolt 5.

[0062] If the gap between the opening / closing door 1 and the side wall assembly 2 measured in the previous step does not meet the preset value, loosen the second bolt 5 but do not remove it. At this time, the second bolt 5 will not prevent the hinge assembly 3 from moving the opening / closing door 1 to adjust the gap, and it can also prevent the hinge assembly 3 from completely disengaging from the side wall assembly 2.

[0063] S3. Unscrew the first bolt 4 from the first through hole 21 and the first threaded hole 31, and screw it back into a suitable set of second through holes 22 and second threaded holes 32.

[0064] Based on the measured gap between the opening / closing door 1 and the side wall assembly 2, the distance between the first threaded hole 31 and the second threaded hole 32, and the distance between the first through hole 21 and the second through hole 22, the unscrewed first bolt 4 is re-screwed into the misaligned second through hole 22 and the matching second threaded hole 32 located on one side of the first through hole 21 and the first threaded hole 31, as shown below. Figure 5 As shown, this includes six sets of second through holes 22 and second threaded holes 32, each of which enables the door 1 and hinge assembly 3 to move left or right, and the moving distances are all different. During the process of screwing the first bolt 4 into the second through holes 22 and second threaded holes 32, because the distance between the first threaded holes 31 and second threaded holes 32 is not equal to the distance between the first through holes 21 and second through holes 22, as the first bolt 4 is gradually screwed in, the hinge assembly 3 drives the door 1 to move in the corresponding direction until the second through holes 22 and second threaded holes 32 are completely aligned and the first bolt 4 is fully screwed in.

[0065] S4. Tighten the second bolt 5.

[0066] After adjusting the position with the first bolt 4, tighten the second bolt 5 to adjust the overall position of the opening and closing door 1.

[0067] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios. These adjustments do not depart from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0068] For example, in an alternative embodiment, the number of the second through hole 22 and the second threaded hole 32 described in the current embodiment, which is six, can be replaced by two or four (not shown in the figure), as long as the number of the second through hole and the second threaded hole facilitates the adjustment of the position of the hinge assembly. These changes do not depart from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0069] For example, in another alternative embodiment, the third through hole 23 and the fifth through hole 26 described in the current embodiment, which are both oblong holes, can be replaced with rectangular holes (not shown in the figure), as long as the hinge body can slide. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0070] For example, in another alternative embodiment, the number of both the third through hole 23 and the third threaded hole 33 described in the current embodiment can be replaced with one each (not shown in the figure), which can also achieve the effect of facilitating the sliding of the hinge body. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0071] For example, in another alternative embodiment, the distance between the first threaded hole 31 and the second threaded hole 32 described in the current embodiment, which is greater than the distance between the first through hole 21 and the second through hole 22, can be replaced by a distance between the first threaded hole and the second threaded hole that is smaller than the distance between the first through hole and the second through hole (not shown in the figure). These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0072] For example, in another alternative embodiment, the structure described in the current embodiment can be replaced with a structure that does not include the decorative panel and adjustable bracket, and other structures are adjusted accordingly. The adjusted structure, excluding the opening and closing door, is as follows: Figure 6-7 As shown:

[0073] A first threaded hole 31, a second threaded hole 32, and a third threaded hole 33 are provided on the hinge body 34. Multiple second threaded holes 32 are provided; preferably, there are six second threaded holes 32, which are equally spaced on both sides of the first threaded hole 31. The hinge body 34 is slidably disposed within a hinge body groove 37 on the side plate 24, and the hinge body groove 37 is fixedly disposed on the inner side of the side plate 24.

[0074] A first through hole 21, a second through hole 22, and a third through hole 23 are provided on the side plate 24. The first through hole 21 and the second through hole 22 are circular holes, and the third through hole 23 is an elongated hole. The center line of the third through hole 23 is parallel to the line connecting the centers of the first through hole 21 and the second through hole 22. Multiple second through holes 22 are provided; preferably, there are six second through holes 22, which are equally spaced on both sides of the first through hole 21. There are two third through holes 23.

[0075] The distance between the first threaded hole 31 and the second threaded hole 32 is not equal to the distance between the first through hole 21 and the second through hole 22. The first bolt 4 passes through the first through hole 21 and is connected to the first threaded hole 31. The second bolt 5 passes through the third through hole 23 and is connected to the third threaded hole 33.

[0076] These do not deviate from the principles of the present invention, and therefore all fall within the protection scope of the present invention.

[0077] For example, in another alternative embodiment, based on the structure described in the previous alternative embodiment, the second bolt 5 and the hinge body 34 can be configured as an integral structure (not shown in the figure). That is, during the adjustment process, the second bolt 5 is not operated, and only the first bolt 4 needs to be operated to achieve the same effect of adjusting the hinge body 34. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0078] For example, in another alternative embodiment, the structure described in the current embodiment can be replaced by having a plurality of evenly distributed first polygonal holes (not shown in the figure) on the hinge assembly and a plurality of evenly distributed second polygonal holes (not shown in the figure) on the sidewall assembly 2, wherein the spacing between two adjacent first polygonal holes is different from the spacing between two adjacent second polygonal holes; at least one of the first and second polygonal holes is provided with a hole connector (not shown in the figure), which can be either a slot or a buckle; the adjusting member is a wedge (not shown in the figure), and the wedge is provided with a wedge connector (not shown in the figure), which can be either a slot or a buckle; since the wedge is a structure with one end smaller than the other and the side is inclined, during the process of passing the smaller end of the wedge through the second and first polygonal holes, the inclined surface of the wedge can also move the hinge 34 to drive the opening and closing door 1 to move. And after the wedge has completed its movement, the hole connector engages with the wedge connector to prevent the wedge from coming out again. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0079] For example, in another alternative embodiment, the oblique hole 27 described in the current embodiment can be replaced with a rectangular hole (not shown in the figure), which can also achieve the effect of facilitating the movement of the hinge body. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0080] For example, in another alternative embodiment, the obstruction hole 27 described in the current embodiment can be replaced with another regular or irregular shape, such as an ellipse (not shown in the figure), as long as it does not hinder the movement of the hinge body. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0081] For example, in another alternative embodiment, the detachable fixed connection between the side panel 24 and the decorative panel 25 described in the current embodiment can be replaced by an integral structure of the side panel and the decorative panel (not shown in the figure). These modifications do not deviate from the principles of the present invention and therefore fall within the protection scope of the present invention.

[0082] For example, in another alternative embodiment, the hinge assembly 3, which is slidably disposed within the hinge body groove 37 on the side wall assembly 2 as described in the current embodiment, can be replaced by the hinge assembly being slidably disposed within a sliding plate (not shown in the figure) on the side wall assembly, which can also achieve the effect of facilitating the sliding of the hinge body. These modifications do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0083] In summary, the microwave baking equipment of the present invention can adjust the gap between the opening and closing door and the side wall assembly without disassembling the entire opening and closing door and hinge assembly, based on the actual situation after the door is installed. This reduces the labor cost of adjusting the microwave baking equipment. Furthermore, during the adjustment process, the operator only needs to rotate the first and second bolts on the side wall assembly from the side of the microwave baking equipment to conveniently adjust the gap between the opening and closing door and the side wall assembly, without applying any additional force to the opening and closing door.

[0084] The microwave baking apparatus of this invention solves the problem of microwave leakage when the gap between the opening / closing door and the side wall assembly is too large, and also solves the problem of the door being unable to open normally when the gap is too small. The microwave baking apparatus of this invention can effectively protect the personal safety of personnel near the microwave baking apparatus without hindering the opening and closing of the door.

[0085] Furthermore, the microwave baking equipment of the present invention can appropriately reduce the dimensional tolerance requirements of the relevant parts of the opening and closing door, thereby reducing the production cost. It also increases the range of opening and closing doors to be selected when maintenance or replacement is required, and reduces the difficulty of replacing the opening and closing door.

[0086] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0087] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
