Description

Technical Field

[0001] The present invention belongs to the field of microwave ovens, and particularly relates to a box-type microwave oven for prefabricated dishes. Background Art

[0002] A microwave oven is a common cooking appliance used to cook or heat food. It uses microwave energy to heat the food placed in the microwave oven cavity. The prefabricated food industry is currently mainly divided into four categories: ready-to-eat, ready-to-heat, ready-to-cook, and ready-to-prepare. Among them, the bagged ready-to-heat prefabricated food is favored by users because of its simple cooking method. The characteristics of the bagged ready-to-heat prefabricated food are "microwave heating and instant consumption inside the bag". Bagged prefabricated foods are usually stored under frozen conditions. Before eating, users need to put the prefabricated food into the microwave oven for heating.

[0003] In the existing solutions, traditional microwave ovens are usually used to heat prefabricated dishes. However, the reflection surface of the microwave in the traditional structure is fixed, and the side wall surface causes the microwave reflection to form a standing wave pattern in the oven, resulting in an uneven energy distribution in the heating space. The formation of this standing wave field usually manifests as excessive energy (heat concentration) in some areas, while insufficient energy (insufficient heating) in other areas. This uneven heating not only affects the heating effect of prefabricated dishes, but may also cause local overheating or even coking, while other parts may not be fully heated, thus affecting the taste and nutrition of the food.

[0052] Compared with the prior art, the traditional box-type microwave oven for prefabricated dishes can only perform microwave heating on prefabricated dishes. Standing waves will be formed during the use of the microwave oven. Standing waves are formed by the reflection and superposition of microwaves in the oven cavity. After the microwaves are emitted, they are repeatedly reflected between the metal walls and superposed with the incident waves to form standing waves, resulting in strong microwave energy (antinodes) in some areas and weak (nodes) in some areas. Standing waves will cause the uneven distribution of microwave energy in the oven body, resulting in uneven heating of prefabricated dishes and energy waste. However, the formation of a standing wave field can be avoided by setting a wave disturbing sheet, and the existence of an eccentric bushing can cause the wave disturbing sheet to form dynamic deformation, thereby diversifying the propagation of microwaves in the oven body, enabling uniform heating and cooking of prefabricated dishes, saving heating time, having high heating efficiency, and reducing energy consumption.

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Please refer to Figures 1-11 As shown, the specific embodiments provided by the present invention are as follows:

[0068] The box-type microwave oven for prefabricated dishes is widely used in places such as families and offices and can quickly heat prefabricated dishes, which include ready-to-eat foods: ready to eat after opening the bag, such as canned foods and marinated flavors. Heat-instant foods: need to be heated, such as frozen dumplings and instant noodles. Ready-to-cook foods: need simple cooking, such as semi-finished steaks and cut vegetables. Ready-to-assemble foods: already cut and need to be cooked by oneself, such as fresh-cut vegetables;

[0069] When the traditional box-type microwave oven for prefabricated dishes heats food, since its heating space and heating inner wall surface are both fixedly arranged, and the fixedly arranged heating inner wall surface serves as a reflecting surface, it will cause the microwave to form regular reflections, making it easier to form standing waves. Standing waves will lead to uneven heating of the food. The food is heated faster at the antinode and slower at the node, resulting in a lower heating efficiency of the furnace body for the food, prolonging the complete heating time, and also causing waste of energy.

[0070] The inner wall surface of the microwave oven body 1 is provided with a groove, and the groove has a certain depth for placing the wave disturbing component 2 without affecting the original heating space of the microwave oven body 1;

[0071] Among them, multiple groups of wave disturbing sheets 201 are hinged to each other to form a dynamic reflecting surface. The driving member 202 drives some of the wave disturbing sheets 201 arranged in abutment to displace them towards or away from the food side. The displacement of the wave disturbing sheets 201 causes the propagation path of the microwave in the cavity to change continuously, reducing the formation of fixed reflection points, thereby reducing the possibility of standing wave generation. When the microwave contacts the wave disturbing sheet 201, the presence of the wave disturbing sheet 201 can disrupt the reflection law of the microwave, making the interference pattern of the incident wave and the reflected wave no longer fixed, thereby reducing the formation of standing waves;

[0072] The material of the wave disturbing sheet 201 is food-grade stainless steel. It not only has excellent corrosion resistance, can effectively resist the erosion of water vapor and acidic and alkaline substances in food, ensuring long-term stable operation, but also has good microwave reflection characteristics. Its high reflectivity helps to enhance the multiple reflections of the microwave in the microwave oven body 1, making the microwave energy evenly distributed, avoiding the formation of a standing wave field, thereby improving the uniformity and heating efficiency of food heating. Among them, the edges of the wave disturbing sheet 201 are rounded. The purpose of rounding is to prevent tip discharge. Simply put, when the microwave oven is working, there is a high-intensity electromagnetic field in the cavity (such as 2.4 GHz microwave). The sharp edges or corners of the metal wave disturbing sheet 201 are prone to form electric field concentration, resulting in air breakdown and even spark generation. The rounding treatment can smooth the electric field distribution, reduce the discharge risk, improve safety, and the rounded wave disturbing sheet 201 can avoid the direction of microwave reflection from being too concentrated at the sharp edges, making the microwave reflection softer, reducing local hot spots, and improving the uniformity of food heating;

[0073] Furthermore, the wave disturbing sheet 201 includes a main sheet and coupling sheets connected to its ends. The main sheets and between the main sheet and the coupling sheets are hinged, and the hinging is fixed by a hinge or a ball joint hinge, etc. The advantage of this hinging method is that it allows the wave disturbing sheet 201 to rotate flexibly within a certain range, facilitating the optimization of the microwave reflection path, improving the heating uniformity, and the hinging installation is convenient, suitable for the environment with limited internal space of the microwave oven body 1, and is also convenient for installation and maintenance and suitable for the wave disturbing sheet 201 that moves frequently. Multiple brackets are arranged inside the microwave oven body 1 for supporting the pre-prepared dishes. The brackets are arranged in the microwave oven body 1 at intervals of a certain distance from top to bottom. The interval distance facilitates the placement of the pre-prepared dishes, and the multi-layer brackets can heat and cook multiple pre-prepared dishes simultaneously, with higher heating efficiency;

[0074] Inside the microwave oven body 1, there are also a microwave guiding device, a microwave stirrer, a control system, and a gallium nitride control circuit. The microwave stirrer is used to disperse the distribution of microwaves in the cavity to ensure uniform heating of food. The microwave stirrer is usually installed on the top of the microwave oven and makes the microwaves evenly distributed in the cavity by reflecting them. The control system includes functions such as time setting, power adjustment, and preset programs. Microwave ovens are usually equipped with a digital display screen and a touch panel, allowing users to conveniently select the heating time and mode, saving time and effort;

[0075] The role of the gallium nitride control circuit is especially the optimization of key links such as radio frequency signal generation, power amplification, output matching, and microwave coupling, which overall improves the heating efficiency and stability of the microwave oven. Compared with the traditional magnetron system, it not only improves the energy transmission efficiency and reduces the reflection loss, but also provides a more stable and uniform microwave energy distribution during the heating process, thus improving the heating effect and energy-saving performance of the microwave oven;

[0076] The gallium nitride control circuit includes a radio frequency signal generation unit, a power amplification unit, an output matching network, a microwave output port module, a waveguide, a microwave coupler, a transmitting antenna, and coupling holes. The radio frequency signal generation unit is used to convert the input direct current signal into a radio frequency signal in the microwave band. The specific implementation method can adopt an oscillation circuit, such as a crystal oscillator or a voltage-controlled oscillator (VCO), to generate a microwave signal with a specific frequency (for example, 2.45 GHz). The power amplification unit consists of a radio frequency power amplifier based on gallium nitride (GaN) material. This unit is responsible for amplifying the low-power radio frequency signal to the required power output level to meet the heating requirements. Generally speaking, this unit has the characteristics of high power density, high thermal stability, and high efficiency, effectively reducing the working temperature of the device, reducing heat loss, and extending the service life. In addition, this unit has excellent anti-aging ability and environmental adaptability, and can maintain a stable power output during long-term operation to ensure the continuous and efficient operation of the system.

[0077] The microwave output port module is connected to the microwave guiding device and is used to output a stable radio frequency signal to the waveguide or other guiding structures. The waveguide is a metal pipe specially used for transmitting microwaves. The microwave coupler is used to achieve efficient coupling between the power amplification unit and the waveguide, which can reduce the reflection loss and ensure the efficient transfer of energy;

[0078] The driving member 202 is a driving motor for driving the linkage member 203. There is a transmission structure between the driving member 202 and the linkage member 203. The transmission structure is connected to the output end of the driving member 202 and can drive the linkage member 203 to rotate. The transmission structure includes a transmission rod and a rotating shaft. The rotating shaft is arranged at the end of the transmission rod, and the transmission rod can drive the rotating shaft to rotate;

[0079] The linkage member 203 includes a shaft structure and an eccentric bushing 206 sleeved thereon. The number of linkage members 203 is multiple groups. The multiple groups of shaft structures are fixed as a whole by means of gears, chains or sprockets. The end of the shaft structure is connected to the rotating shaft. The driving member 202 can drive the shaft structure to rotate. At least part of the structure of the eccentric bushing 206 abuts against the wave disturbing piece 201. Specifically, when the shaft structure rotates, the eccentric bushing 206 rotates synchronously, and then displaces the abutted wave disturbing piece 201 towards or away from the food side, connecting the wave disturbing piece 214 and the secondary wave disturbing piece 213 to tilt synchronously. Thus, the overall microwave reflecting surface formed by multiple groups of wave disturbing pieces 201 will present a continuous concave-convex shape. This reflecting surface structure can change the reflection path of microwaves and avoid the generation of standing wave fields;

[0080] In addition, due to the characteristics of its own structure, when the eccentric bushing 206 rotates, the eccentricity continuously changes, so that the displacement amount of the wave disturbing piece 201 abutted against the eccentric bushing 206 continuously changes. Thus, multiple groups of wave disturbing pieces 201 form a dynamically changing microwave reflecting surface, further disrupting the reflection law of microwaves, making the microwaves in the microwave oven body 1 evenly distributed, reducing energy waste, improving the heating efficiency, shortening the heating time, effectively avoiding the formation of standing wave fields, and ensuring more uniform food heating;

[0081] Specifically, the change in the shape of the wave disturbing piece 201 can change the reflection, refraction and path of microwaves, directly affecting the distribution of microwaves in the oven cavity, and avoiding the appearance of local overcooled or overheated areas. The existence of local overcooled or overheated areas will affect the heating of food, resulting in uneven heating or uneven cooking of food. Therefore, the existence of the wave disturbing piece 201 can effectively solve such problems, greatly improving the heating efficiency of the furnace body and reducing energy consumption.

[0082] As Figures 1 to 10 shown, the second embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. The number of linkage shafts 204 is multiple groups. The multiple groups of linkage shafts 204 are arranged at a certain distance. The distance between them can ensure that the eccentric bushings 206 rotate independently without contacting and colliding with each other. The eccentric bushing 206 is of an elliptical cylindrical structure. Anti-slip stripes are provided at the connection between the eccentric bushing 206 and the linkage shaft 204. The anti-slip stripes can improve the coupling stability between the linkage shaft 204 and the eccentric bushing 206. A detachable clamping member is provided at the end of the linkage shaft 204. The clamping member is connected to the linkage shaft 204 by plugging or clamping. The clamping member is at least provided at the end of the linkage shaft 204 to limit the position of the eccentric bushing 206 without affecting the disassembly of the eccentric bushing 206;

[0083] The linkage wheel 205 is used to assist the linkage shaft 204 in rotating, thereby improving the rotational stability of the linkage shaft 204. The chain belt 207 can fix multiple linkage shafts 204 into a whole, so that the driving member 202 drives multiple groups of linkage shafts 204 to rotate synchronously. The eccentric bushing 206 makes an asymmetric movement to dynamically adjust the shape of the wave disturbing sheet 201. The deformed wave disturbing sheet 201 can effectively avoid the formation of a standing wave field, thereby improving the heating uniformity and heating efficiency of the microwave oven.

[0084] Multiple groups of raised blocks with different sizes or shapes can also be arranged on the outer wall surface of the eccentric bushing 206. The purpose of the raised blocks is to enable the wave disturbing sheet 201 to form a dynamic deformation. When the linkage shaft 204 rotates, due to the existence of the eccentric bushing 206 and the raised blocks, the acting force on the wave disturbing sheet 201 is different when the linkage shaft 204 rotates to different angles, thereby causing the deformation displacement and direction of the wave disturbing sheet 201 to be different, effectively avoiding the formation of standing waves, and improving the heating efficiency and heating uniformity of the furnace body for food.

[0085] As Figures 1 to 8 shown, the third embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. The installation chamber 208 is independently arranged from the original heating space of the microwave oven body 1, avoiding occupying the original heating space of the furnace body. The elastic member 209 can be an elastic band or a spring structure. The elastic member 209 can provide elastic force for the deformation of the wave disturbing sheet 201. The function of the elastic force is to ensure that a part of the structure of the wave disturbing sheet 201 is always in contact with the eccentric bushing 206. The purpose of always being in contact is that when the driving member 202 drives the linkage shaft 204 to rotate, the eccentric bushing 206 can always change the shape of the wave disturbing sheet 201, thereby effectively avoiding the formation of a standing wave field so that the microwaves are evenly distributed in the cavity of the microwave oven body 1.

[0086] The shape and size of the installation hole 210 are adapted to the shape and size of the elastic member 209. The installation hole 210 allows a part of the structure of the elastic member 209 to pass through. The elastic member 209 is arranged at both ends of the wave disturbing sheet 201 to provide elastic force for its deformation. The sealing member 211, as a sealing structure, can seal the installation hole 210 to avoid microwave leakage, which may cause adverse effects on human health, equipment performance, and the surrounding environment.

[0087] The sealing member 211 is made of a material that is resistant to high temperature, water vapor, and aging, and materials such as silicone rubber can be selected. Multiple groups of shallow grooves can be arranged on the inner wall of the installation hole 210. Raised portions are provided on the outer wall of the sealing member 211, which are adapted to the size and quantity of the shallow grooves. The raised portions can be coupled with the shallow grooves to further improve the sealing effect. Connecting members are provided on both side walls of the sealing member 211 to connect with the elastic member 209.

[0088] Specifically, the deformation of the spoiler 201 drives the sealing member 211 to slide within the mounting hole 210. On the one hand, the sealing member 211 does not affect the tensile deformation of the elastic member 209, and on the other hand, it does not affect its sealing effect on the mounting hole 210.

[0089] As Figures 2 to 3 shown, the fourth embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. A through hole is provided on the main spoiler 212, and the through hole allows microwaves to pass through or penetrate. The setting of the through hole helps to diversify the propagation path of microwaves in the furnace body, thereby further breaking the formation of the standing wave field and avoiding local heat concentration:

[0090] The secondary spoiler 213 is rotatably connected to the microwave oven body 1, and the rotational connection is achieved by means of a rotating shaft rod or a shaft pin structure. The rotatably connected secondary spoiler 213 can assist the main spoiler 212 in deforming and displacing. The connecting spoiler 214 can connect multiple secondary spoilers 213 into a whole. The number of spoilers 201 installed is determined according to the size and energy consumption of the microwave oven body 1. Too many spoilers 201 may cause loss of microwave energy, reduce efficiency, and even cause local overheating or equipment failure, etc.;

[0091] Among them, the connecting spoiler 214 and the secondary spoiler 213 are hinged by means of a roller bearing or a shaft pin and an elastic hinge. This hinged method, on the one hand, allows a certain distance of movement between adjacent secondary spoilers 213, and on the other hand, facilitates installation and maintenance;

[0092] The driving member 202 is used to drive the main spoiler 212 to move towards or away from the food direction. Due to the existence of the secondary spoiler 213 and the connecting spoiler 214, the driving member 202 only needs to be connected to a part of the main spoiler 212 to drive the whole spoiler 201 to displace and deform, thereby disturbing the microwaves in the furnace body and effectively avoiding the formation of the standing wave field;

[0093] All in all, multiple groups of spoilers 201 can form dynamic deformation, which helps to diversify the propagation path of microwaves in the furnace body, avoid local heat concentration, and improve the heating uniformity of prefabricated dishes.

[0094] As Figure 5 shown, the fifth embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. The sliding member 215 facilitates the movement of the main spoiler 212. A coupling groove is provided on the side of the main spoiler 212. A ball-headed connecting rod can also be added between the coupling groove and the sliding block 217. The ball part of the ball-headed connecting rod is movably connected to the coupling groove, the shape of the coupling groove is adapted to the shape of the ball part, and the rod part is movably connected to the sliding block 217. The setting of the ball-headed connecting rod can ensure that when the main spoiler 212 displaces, the ball-headed connecting rod displaces, thereby facilitating the sliding block 217 to slide along the sliding groove 216 direction;

[0095] The number of the sliding blocks 217 and the sliding grooves 216 can be set in multiple groups. The arrangement of the sliding blocks 217 and the sliding grooves 216 can assist the main spoiler 212 in displacement, and the sliding manner makes it easier for the driving member 202 to drive the main spoiler 212. A fixing groove is provided on the inner wall of the cavity of the microwave oven body 1 for fixing the sliding groove 216;

[0096] Wherein, detachable stopper structures are further provided on both sides of the opening of the sliding groove 216. The detachable connection can be a snap connection or a plug connection. The detachable connection method facilitates the coupling or separation of the sliding block 217 and the sliding groove 216, which is convenient for installation and later maintenance. At least part of the stopper structure can limit the sliding of the sliding block 217 to prevent the two from slipping and separating, and the sliding stability and reliability are higher;

[0097] Such as Figure 2 As shown, the sixth embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. A connection groove is provided at the corresponding position on the top or bottom of the inner wall of the microwave oven body 1 for fixing the limiting member 218;

[0098] The limiting member 218 is in an overall strip structure. The strip structure can reduce the space occupation and avoid affecting the energy consumption of the furnace body for heating food. A plurality of through holes are provided on the strip structure, and the through holes allow microwaves to pass through. The shapes of the through holes are set in multiple different types. The through holes with different shapes can further adjust the reflection of microwaves, thereby effectively avoiding the formation of a standing wave field, changing the propagation path of microwaves in the furnace cavity, avoiding the formation of hot spots and cold spots, making the food heated more evenly, and at the same time improving the heating efficiency and safety of the equipment;

[0099] At least part of the limiting member 218 can limit the displacement amplitude of the connecting spoiler 214. The function of limiting the displacement of the connecting spoiler 214 is that when a main spoiler 212 is displaced by the external force of the driving member 202 at a certain place, it will drive the secondary spoilers 213 coupled on both sides of the connecting spoiler 214 to make synchronous displacement. At this time, due to the existence of the limiting member 218, the position of the connecting spoiler 214 can be limited, and then the main spoiler 212 in contact with the driving member 202 and the adjacent main spoilers 212 form a concave-convex shape similar to a wave.

[0100] Such as Figures 1 to 7As shown, the seventh embodiment of the present invention proposes a box-type microwave oven for pre-prepared dishes. The hinged manner facilitates the displacement of the main spoiler plate 212 under the action of external force. A fixing frame is provided in the cavity of the microwave oven body 1 for fixing the sliding rail 221. The number of the sliding rail 221 and the hinge claw 220 can be set in multiple groups to be connected to the auxiliary spoiler plates 213 respectively, or one group can be set to connect multiple groups of auxiliary spoiler plates 213 into a whole at the same time. The setting of the hinged portion 219 will not affect the displacement of the spoiler plate 201 on the one hand, and can improve the stability of the overall structure on the other hand.

[0101] The articulated claw 220 is provided with a plurality of rotation connection points, which facilitate the displacement of the spoiler plate 201 on the one hand, and facilitate the sliding of the articulated claw 220 along the sliding track 221 on the other hand. The sliding connection can be in the form of a pulley and a track;

[0102] The sliding track 221 disposed on the side away from the food is convenient for reflecting microwaves and will not affect the microwave heating of food. The structure of the sliding track 221 on the food side is provided with a raised stopper, which can limit the sliding of the hinge claw 220 to prevent the two from slipping and separating, thereby affecting subsequent use;

[0103] like Figures 2 to 3 As shown, the eighth embodiment of the present invention provides a box-type microwave oven for pre-prepared dishes, wherein the driving part 222 is a driving motor or an electromagnetic structure, etc., and an installation space is provided on the inner wall of the microwave oven body 1 for placing the driving part 222, and the transmission part 223 can transmit the force of the driving part 222 to the linkage shaft 204 to drive it to rotate;

[0104] The driving part 222 is also provided with a control device, which can control the rotation and rotation rate of the driving part 222 driving the linkage shaft 204. The control device can dynamically control the driving part 222 to make the linkage shaft 204 rotate dynamically, thereby making the whole spoiler plate 201 dynamically deformed.

[0105] The control device may adopt a PLC controller to control the rotation speed, rotation direction, etc. of the linkage shaft 204 in a periodic, linear, or nonlinear manner, thereby improving the distribution of microwaves and ensuring uniform heating of food.

[0106] like Figure 11 As shown, the ninth embodiment of the present invention provides a box-type microwave oven for pre-prepared dishes, wherein the mounting hole 210 is for the elastic member 209 to pass through, one end of the elastic member 209 is connected to the inner wall of the mounting chamber 208, and the other end is connected to the spoiler plate 201, and the blocking member 211 is used as a sealing structure to seal the mounting hole 210 to prevent safety accidents caused by microwave leakage;

[0107] Specifically, the driving member 202 drives the linkage shaft 204 to rotate, thereby driving the eccentric bushing 206 to rotate synchronously. At this time, the partial spoiler 201 in contact with the eccentric bushing 206 moves away from or towards the food side, thereby stretching the elastic member 209. The stretched elastic member 209 drives the sealing member 211 to slide within the mounting hole 210. The mounting hole 210 has certain dimensional limitations. Therefore, it is necessary to limit the sliding of the sealing member 211 within a specific range. Therefore, it is necessary to use the retaining piece 224 to limit the sliding of the sealing member 211 to limit its sliding range within the mounting hole 210 to avoid slipping and separation, causing microwave leakage;

[0108] The connection between the retaining piece 224 and the mounting hole 210 can be plug-in or socket connection. At least part of the structure of the retaining piece 224 serves as a cross-section for limiting the movement of the sealing member 211, thereby improving the overall sealing performance of the furnace body and having a higher safety factor.

[0109] As Figures 2 to 8 shown, the tenth embodiment of the present invention proposes a box-type microwave oven for prefabricated dishes. The auxiliary structure 225 is used to assist the elastic member 209 in stretching and deforming. One end of the elastic member 209 is wound around the rotating shaft 226. The elastic member 209 has a certain length, and at least part of the structure is wound around the rotating shaft 226. When the spoiler 201 is displaced, the elastic member 209 is stretched and drives the rotating shaft 226 to rotate in the stretching direction. The rotating shaft 226 is provided with a clamping groove for clamping the end of the elastic member 209;

[0110] The torsion spring 227 is sleeved on the rotating shaft 226. The outer wall surface of the rotating shaft 226 is provided with a clamping groove for clamping the extended structure of the torsion spring 227. The other end structure of the torsion spring 227 is fixed on the wall of the installation chamber 208. When the rotating shaft 226 rotates under the stretching of the elastic member 209, the clamping groove drives the torsion spring 227 to rotate synchronously, thereby stretching the torsion spring 227. The torsion spring 227 will recover to its initial state under the action of its own elastic force, thereby providing an opposite acting force to the rotating shaft 226. The setting of the torsion spring 227 can ensure that the elastic member 209 is always in contact with the spoiler 201;

[0111] All in all, due to the presence of the eccentric bushing 206, when the eccentric bushing 206 rotates, the deformation amount of the spoiler 201 is different. There are theoretically minimum and maximum deformations. At this time, the stretching force acting on the elastic member 209 has minimum and maximum values, and the elastic force of the elastic member 209 itself has a maximum value. To avoid the situation that the elastic member 209 loses its elastic force and cannot be restored due to excessive stretching, the rotating shaft 226 and the torsion spring 227 are provided to ensure its appropriate stretching and not exceeding the limit.
