Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a box-type industrial microwave oven. Background Technology

[0002] As an important industrial production equipment, the box-type industrial microwave oven consists of multiple components such as a microwave oven cavity and a microwave generator. It works based on the principle that microwaves cause polar molecules in materials to generate heat through friction. It has the performance characteristics of efficient and rapid heating, uniform heating, energy saving and environmental protection. It is widely used in many fields such as food processing, chemical industry, ceramics, and pharmaceuticals. For example, it is used for drying and sterilizing food, drying and accelerating reactions of chemical raw materials, processing ceramic blanks and drying and sterilizing pharmaceuticals. It plays a key role in improving the production efficiency and product quality of various industries.

[0003] Current box-type industrial microwave ovens face a significant challenge during prolonged continuous operation: the objects being heated often splatter, and this splatter accumulates on the inner walls of the microwave oven, forming a large amount of hard, sticky dirt. This dirt is not only tightly adhered but also hard, making subsequent cleaning extremely inconvenient and often requiring substantial manpower and time. Furthermore, in terms of heating principles and efficiency, existing microwave ovens primarily rely on the refraction of microwaves on the inner walls to heat materials, employing diffuse reflection. This heating mode has certain limitations. During energy transfer, due to the characteristics of diffuse reflection, microwaves cannot be efficiently concentrated on the heated material, resulting in a relatively low overall heating efficiency. This makes it difficult to meet the needs of some industrial production scenarios with high heating efficiency requirements, thus limiting the wider and more efficient application and development of box-type industrial microwave ovens in the industrial field.

[0004] Therefore, this utility model provides a box-type industrial microwave oven to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a box-type industrial microwave oven, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a box-type industrial microwave oven, including a microwave oven structure, wherein the microwave oven structure includes a microwave oven body, characterized in that: a cladding sheet is provided inside the microwave oven body along the internal path of the box, and a rotating tray is rotatably provided at the center position of the lower part of the microwave oven body;

[0007] The rotating tray has a prism-shaped rotating shaft integrally formed at the center of its lower surface. The shaft slides through an upward-opening prism hole at the center of the rotating base, and is slidably connected to the rotating base. A connecting spring sleeved on the outside of the prism-shaped rotating shaft provides buffering and connection. Several rods are fixed in a ring array along the axis on the circumferential side of the prism-shaped rotating shaft. The rotating base has a C-shaped air passage extending from the slot into which the prism-shaped rotating shaft slides downwards to the centrifugal direction. A lifting air pipe is fixed at one end of the air passage, and a top rod is slidably fixed inside the lifting air pipe.

[0008] The outer periphery of the package has a gasket evenly fixed between it and the wall of the microwave oven body. The surface of the package that is attached to the wall has evenly cut holes without affecting the gasket. The surface of the package facing the rotating tray has a centripetal refraction groove evenly formed between the cut holes to refract microwaves emitted by the microwave oven body towards the rotating tray. The middle bottom plate of the package has a through hole corresponding to the rotating tray. Several elastic brackets are fixed in a circular array along the axis on the ring wall of the through hole. Several lifting rod grooves are formed on the surface of the package around the through hole where the elastic brackets are located.

[0009] Preferably, the microwave oven body has a control panel on the upper front side, and a window that opens into the microwave oven body is provided on the front side, and the window is rotatably connected to the sealing door through a connector.

[0010] Preferably, the rotating tray is connected to a drive assembly disposed inside the microwave oven body and is driven by the rotation of the drive assembly.

[0011] Preferably, the upper end of the push rod is provided with a ball bearing, and the position of the push rod corresponds to that of the lifting rod groove. The lower end of the lifting rod groove has rounded corners on the edge of the annular path.

[0012] Preferably, the cut hole has rounded corners at the port away from the box wall, so that the port of the cut hole close to the box wall has a cutting edge.

[0013] Preferably, the elastic bracket and the hitting rod are initially in the same plane.

[0014] Beneficial effects

[0015] This utility model provides a box-type industrial microwave oven, which has the following advantages compared with the prior art:

[0016] (1) During the heating process, the rotating tray of this box-type industrial microwave oven rotates under the drive of the drive component, which makes the material constantly turn over and ensures that the material is heated evenly. At the same time, the centripetal refractive groove on the plate can effectively change the direction of microwave refraction, concentrate the microwaves and refract them towards the rotating tray position, so that the microwave energy acts on the material more accurately and reduces energy dispersion. Moreover, as the rotating tray rotates, the top rod moves along the lifting rod groove and lifts the plate, so that the microwave intersection point moves up with the plate, further realizing focused heating of different positions of the material. This multi-faceted synergistic effect effectively overcomes the problem of low efficiency of diffuse reflection heating in traditional microwave ovens, greatly shortens the heating time, and improves production efficiency. In industrial production, it can complete material processing tasks faster, such as drying and sterilization in food processing, drying and reaction acceleration of chemical raw materials, etc., saving time costs for enterprises and increasing production capacity.

[0017] (2) The box-type industrial microwave oven uses a control device to make the rotating tray rotate in a low-temperature heating mode. At this time, the striking rod will intermittently strike the elastic corner frame, and the vibration will be transmitted to the packing plate. The continuously vibrating packing plate can remove the dirt attached to its own surface on the one hand, and on the other hand, in conjunction with the cutting hole, vibrate and cut off the dirt on the inner wall of the microwave oven body. This vibration cleaning method does not require manual cleaning, reduces manpower input and cleaning time, avoids the problem of equipment performance degradation caused by untimely or incomplete manual cleaning, ensures the long-term stable operation of the equipment, reduces equipment maintenance costs, extends equipment service life, and keeps the equipment in good working condition during long-term operation, thus improving the reliability and economy of the equipment.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-6 A box-type industrial microwave oven includes a microwave oven structure 1, which includes a microwave oven body 11. The upper front side of the microwave oven body 11 has a control panel, and a window that opens into the microwave oven body 11 is provided on the front side. The window is rotatably connected to a sealing door 12 via a connector. Inside the microwave oven body 11, a cover plate 15 is provided against the wall according to the internal path. A rotating tray 13 is rotatably provided at the center of the lower part of the microwave oven body 11. The rotating tray 13 is connected to a drive assembly configured inside the microwave oven body 11 and is driven by the rotation of the drive assembly.

[0028] The rotating tray 13 is a grid-shaped tray frame. A prism rotating shaft 131 is integrally provided at the center of the lower surface of the frame. The prism rotating shaft 131 slides into the upward-opening prism hole at the center of the rotating seat 132 and is sealed and slidably connected to the rotating seat 132. A connecting spring 133 sleeved and connected to the outside of the prism rotating shaft 131 provides buffering and connection limitation. A C-shaped air passage 1321 is provided inside the rotating seat 132 from the slot into which the prism rotating shaft 131 slides downward to the centrifugal direction. A lifting air pipe 1322 is fixedly provided at one end of the air passage 1321. A top rod 1323 is slidably limited inside the lifting air pipe 1322. A ball bearing is rolled at the upper end of the top rod 1323.

[0029] A gasket 153 is evenly fixed between the outer peripheral surface of the cover plate 15 and the wall of the microwave oven body 11. The surface of the cover plate 15 that is attached to the wall is evenly provided with holes 151 without affecting the gasket 153. The ends of the holes 151 that are far from the wall are rounded so that the ends of the holes 151 that are close to the wall have a cutting edge. The surface of the cover plate 15 facing the rotating tray 13 is evenly provided with centripetal refractive grooves 152 between the holes 151 to refract microwaves emitted by the microwave oven body 11 to the position of the rotating tray 13.

[0030] The surface of the cover piece 15 has several lifting rod grooves 154 around the through hole where the elastic corner bracket 155 is located, and the lower end of the lifting rod groove 154 is rounded to the edge on the annular path.

[0031] During operation, the material is first placed on the rotating tray 13. The weight of the material causes the rotating tray 13 to move the prism shaft 131 downward, compressing the connecting spring 133. The striking rod 1311 moves out of the plane of the elastic bracket 155. The downward movement of the prism shaft 131 allows the safety gas in the air passage 1321 to enter the lifting air pipe 1322, pushing the top rod 1323 into the lifting rod groove 154. Then, the sealing door 12 is closed and the heating program is started. The microwave generator works to generate microwaves, and the drive component drives the rotating tray 13 to rotate. The top rod 1323 moves along the lifting rod groove 154 and lifts the package 15, so that the microwave intersection point moves upward with the package 15, realizing focused heating of different positions of the material.

[0032] In summary, during the heating process, the rotating tray 13 rotates under the drive of the drive assembly, causing the material to tumble continuously and ensuring uniform heating. Simultaneously, the centripetal refractive groove 152 on the package 15 effectively changes the microwave refraction direction, concentrating the microwaves towards the rotating tray 13, allowing the microwave energy to act more precisely on the material and reducing energy dispersion. Furthermore, as the rotating tray 13 rotates, the top rod 1323 moves along the lifting rod groove 154 and lifts the package 15, causing the microwave intersection point to move upwards with the package 15, further achieving focused heating of different positions on the material. This multi-faceted synergistic effect effectively overcomes the low efficiency problem of diffuse reflection heating in traditional microwave ovens, significantly shortening heating time and improving production efficiency. In industrial production, it enables faster completion of material handling tasks, such as drying and sterilization in food processing, and drying and reaction acceleration of chemical raw materials, saving enterprises time and increasing production capacity.

[0033] Example 2:

[0034] Please see Figure 5-6 This embodiment provides a technical solution based on embodiment one: the prism pivot 131 is convex, and several striking rods 1311 are fixed in a ring array along the axis on the circumferential side of the column with a larger radius.

[0035] The bottom plate in the middle of the package 15 is convex in the shape of an arch bridge, and a through hole of a specified radius is opened at the center of the convex plate corresponding to the rotating tray 13. Several elastic brackets 155 are fixed in a ring array along the axis on the ring wall of the through hole. Initially, the elastic brackets 155 and the striking rod 1311 are on the same plane.

[0036] After prolonged use and heating, when there is no material on the rotating tray 13, the rotating tray 13 is idled by low-temperature heating through the control device. Since the striking rod 1311 and the elastic bracket 155 are coplanar, the striking rod 1311 will intermittently strike the elastic bracket 155 when the prism shaft 131 rotates, causing it to vibrate and transmit the vibration to the cover plate 15. The continuously vibrating cover plate 15 can remove the dirt attached to the surface. At the same time, in conjunction with the cutting hole 151, the dirt on the inner wall of the microwave oven body 11 is vibrated and cut off, thereby achieving vibration cleaning of the inside of the microwave oven body 11.

[0037] In summary, by using a control device to make the rotating tray 13 idle in a low-temperature heating manner, the striking rod 1311 intermittently strikes the elastic bracket 155, and the vibration is transmitted to the covering plate 15. The continuously vibrating covering plate 15 can remove dirt attached to its own surface on the one hand, and on the other hand, in conjunction with the cutting hole 151, vibrate and cut off the dirt on the inner wall of the microwave oven body 11. This vibration cleaning method does not require manual cleaning, reduces labor input and cleaning time, avoids the problem of equipment performance degradation caused by untimely or incomplete manual cleaning, ensures long-term stable operation of the equipment, reduces equipment maintenance costs, extends equipment service life, and keeps the equipment in good working condition during long-term operation, thus improving the reliability and economy of the equipment.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working Principle: During operation, the material to be heated is first placed on the rotating tray 13. Under the influence of gravity, the rotating tray 13 is forced to move downwards along the slot of the air passage 1321, causing the prism shaft 131 to move linearly downwards. During this movement, the connecting spring 133 is compressed, and the push rod 1311 moves out of the plane of the elastic bracket 155. Simultaneously, as the prism shaft 131 moves downwards, the safety gas stored inside the air passage 1321 is forced to enter the lifting air pipe 1322 along the air passage 1321. The push rod 1323, located inside the lifting air pipe 1322, moves upwards along the lifting air pipe 1322 under the action of the safety gas and extends into the slot of the lifting rod groove 154. Then, the sealing door 12 is closed, and the heating program is started through the control device on the control panel above the front of the microwave oven body 11. At this time, the microwave generator starts working and generates microwaves. At the same time, the drive assembly of the microwave oven body 11 starts to drive the rotating tray 13 to rotate through the turntable 132. During the rotation, the push rod 1323 moves along the air passage 1321 to enter the lifting air pipe 1322. The lifting rod groove 154 moves, and after contacting the edge of the groove, it gradually supports the packing plate 15 upwards. At this time, the microwave intersection point, which was originally refracted onto the material surface by the centripetal refraction groove 152, will move upwards as the packing plate 15 moves upwards, thereby performing focused heating of the material at different positions and improving heating efficiency. After long-term use, without placing any material on the rotating tray 13, the device can be used to drive the rotating tray 13 to perform low-temperature heating via the control device on the upper front panel of the microwave oven body 11. When the turntable 13 is idling, since the striking lever 1311 and the elastic bracket 155 are on the same plane, the striking lever 1311, which rotates with the prism axis 131, will intermittently strike the elastic bracket 155, causing the elastic bracket 155 to vibrate and transmit the vibration to the cover plate 15. The continuously vibrating cover plate 15 will remove the dirt attached to the surface. At the same time, it will work with the cutting hole 151 to vibrate and cut off the dirt on the inner wall of the microwave oven body 11, thereby performing vibration cleaning of the inside of the microwave oven body 11.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
