[0042] Example 1

[0043] like Figure 1-5 As shown, a microwave oven cooking device according to an exemplary embodiment of the present application comprises: a door 1.

[0044] The main body part 2 comprises: a cavity 100 having a first inner wall and a top wall 110 , wherein the first inner wall and the top wall 110 are located at different sides of the cavity.

[0045] The convection system 200 includes an inner heat insulation board 210 and at least one set of fan blade assemblies 220. The inner heat insulation board divides the cavity into a heating cavity 162 and an inner heat insulation cavity 161. The inner heat insulation cavity is formed between the inner heat insulation board 210 and the first inner wall 140. The inner heat insulation board 210 is provided with an air inlet 211 and an air outlet 212. The at least one set of fan blade assemblies is partially placed in the inner heat insulation cavity. When the fan blade assemblies are working, the gas enters the inner heat insulation cavity from the air inlet and flows back to the heating cavity through the air outlet, forming at least one circulating airflow in the cavity to promote the flow of gas in the cavity, and heats the items in the cavity by forced heat convection.

[0046] The microwave system 300 includes a microwave generating assembly and a microwave stirring assembly. A microwave exit area 111 is provided on the top wall 110. The microwave generated by the microwave generating assembly is stirred by the microwave stirring assembly and then emitted into the cavity from the microwave exit area 111.

[0047] The first heating element 400 is disposed in the heating zone 112 . The heating zone 112 is disposed on the top wall 110 and outside the microwave emission zone 111 . The first heating element 400 heats the objects in the cavity by means of heat radiation.

[0048] Compared with the prior art, the microwave steam-bake cooking device of the embodiment of the present application sets the microwave exit area on the top wall, which effectively solves the problem in the prior art that microwaves emitted from the bottom are easily affected by water or residue at the bottom of the cavity, or even the microwave function is damaged.

[0049] Furthermore, through a microwave system with a microwave stirring assembly, the microwaves are stirred evenly and then emitted into the cavity from the microwave exit area of ​​the top wall, thereby eliminating the turntable in the prior art while ensuring that the microwaves heat the food evenly, and also avoiding the problem of water generated during the cooking process damaging the bottom turntable.

[0050] Furthermore, a first heating element is arranged on the top wall, and the first heating element is arranged in a heating zone outside the microwave exit zone. While achieving thermal radiation heating of the food in the cavity, the microwaves can be prevented from being blocked or reflected by the first heating element, thereby effectively improving the uniformity and conduction efficiency of the microwaves when entering the cavity.

[0051] Furthermore, a convection system is arranged on the first inner wall, and the circulating airflow formed by the convection system promotes the flow of gas in the cavity so that the heat at each position in the cavity is uniform, thereby ensuring the cooking effect. In addition, since the convection system and the microwave exit area are arranged on the first inner wall and the top wall on different sides, on the one hand, the first inner wall can be left to the convection system as much as possible, so that when the distance between the inner insulation board and the first inner wall is constant, the size of the inner insulation board can be increased to enlarge the inner insulation cavity, which improves the convection effect of the airflow to a certain extent, and also relatively increases the volume of the heating cavity; on the other hand, it can prevent the convection system from interfering with the microwave system.

[0052] The microwave oven cooking device of the embodiment of the present application also includes a steam system, which includes a steam generator, a water tank, a water pipeline connecting the water tank, the steam generator and the water tank, and a steam pipeline connecting the steam generator and the cavity. The water in the water tank enters the steam generator through the water pipeline to generate steam, which enters the cavity through the steam pipeline to steam cook the food in the cavity. The steam system is not shown in the figure without affecting understanding.

[0053] In the embodiment of the present application, the first inner wall is the rear wall 140 of the cavity, and the convection system 200 is arranged on the rear wall.

[0054] In the embodiment of the present application, the convection system 200 includes: an inner heat insulation board 210 and a set of fan blade components 220. The inner heat insulation board divides the cavity into a heating cavity 162 and an inner heat insulation cavity 161. Figure 5 As shown, the heating chamber 162 is located at the front of the chamber, and the inner heat insulation chamber 161 is located at the rear of the chamber. The inner heat insulation chamber 161 is formed between the inner heat insulation board 210 and the rear wall 140, and the inner heat insulation board is provided with a group of air inlets 211 and air outlets 212.

[0055] The fan blade assembly 220 is partially placed in the inner insulation cavity 161. Specifically, the fan blade assembly 220 includes a motor shaft 221 passing through the first inner wall, a motor 222 connected to one end of the motor shaft, and a fan blade 223 connected to the other end of the motor shaft. The fan blade 223 is located in the inner insulation cavity 161, and the motor 222 is located outside the cavity. When the fan blade assembly is working, the gas enters the inner insulation cavity 161 from the air inlet 211 and flows back to the heating cavity 162 through the air outlet 212, forming a circulating airflow in the cavity to promote the flow of gas in the cavity, and heat the items in the cavity by forced heat convection.

[0056] Preferably, the air inlet is located in the middle of the inner heat insulation board, and the air outlet is located around the inner heat insulation board. The fan blade assembly adopts a centrifugal fan blade. When the centrifugal fan blade is working, the gas in the heating chamber is sucked from the air inlet into the inner heat insulation chamber, diffused to the surroundings after passing through the centrifugal fan blade, and returned to the heating chamber from the air outlet located around the inner heat insulation board.

[0057] In some preferred embodiments, the micro-steaming and baking cooking device of this embodiment further includes a second heating element 230, which is arranged in the inner insulation cavity 161 and combined with the convection system to form a hot air convection system for secondary heating of the gas entering the inner insulation cavity from the heating cavity to improve the heating efficiency. When used in conjunction with the first heating element 400, the adjustment range of the heating power can be increased to achieve a better cooking effect. Preferably, the second heating element 230 is a heating tube, which is arranged around the fan blades, and when the gas diffuses from the centrifugal fan blades to the surroundings, it is heated again. Of course, the heating tube can also be arranged only on the inner insulation cavity, and it is not necessarily required to be arranged around the fan blades. It is feasible to arrange the heating tube in front of the fan blades and on the periphery. The second heating element can also be other heat sources, such as heating wires, heating plates, heating films, etc.

[0058] In other preferred embodiments, the air inlet 211 and the air outlet 212 of this embodiment are both composed of a plurality of through holes, and the diameter of each through hole is less than or equal to 5 mm. On the one hand, the multiple through hole design can compress the gas to form forced convection, and on the other hand, setting the through hole diameter to less than 5 mm can effectively prevent the microwave in the heating cavity 162 from entering the inner insulation cavity 161 through the through hole when the microwave function is used, and then leaking out of the cavity from the gap between the motor shaft 221 of the fan blade assembly and the first inner wall 140, thereby improving the microwave leakage prevention effect of the microwave steaming and baking cooking device of this embodiment.

[0059] In other preferred embodiments, the microwave oven cooking device of this embodiment includes a second heating element 230, and the air inlet 211 and the air outlet 212 on the inner insulation board 210 are composed of multiple through holes, and the diameter of each through hole is less than or equal to 5 mm.

[0060] In the embodiment of the present application, the microwave system 300 includes a microwave generating component and a microwave stirring component. A microwave exit area 111 is provided on the top wall 110. The microwaves generated by the microwave generating component are stirred by the microwave stirring component and then emitted into the cavity from the microwave exit area.

[0061] Specifically, the microwave system 300 includes a microwave generating assembly, which includes a magnetron (not shown in the figure), a waveguide 310, etc. One end of the waveguide is connected to the magnetron, and the other end is connected to the top of the cavity. In the embodiment of the present application, the microwave generating assembly is preferably placed at the top or back of the cavity to shorten the length of the waveguide as much as possible, shorten the propagation distance of the microwave from the magnetron outlet to the top of the cavity, and reduce microwave consumption. The microwave stirring assembly 320 includes a stirring blade 321 and a motor 322 connected to the stirring blade. The stirring blade is located in the microwave containing cavity 170 of the cavity. After the microwave enters the microwave containing cavity from the waveguide, it is stirred evenly by the stirring blade in the microwave containing cavity, and finally emitted from the microwave exit area 111 into the heating cavity 162 of the cavity.

[0062] The microwave exit area 111 is a microwave exit port opened on the top wall 110. Specifically, in the embodiment of the present application, the top of the cavity 100 has a microwave accommodating cavity 170 recessed into the inner surface of the top wall, the microwave accommodating cavity has a lower opening 172 facing the heating cavity, and an upper opening 171 connected to the waveguide, the lower opening 172 is the microwave exit port, forming the microwave exit area 111 described in the embodiment of the present application.

[0063] After the microwave enters the microwave holding cavity from the upper opening, it is stirred evenly by the stirring blade, and then emitted from the microwave exit area and diffused evenly in the heating cavity, which effectively improves the microwave uniform heating effect on the food, and eliminates the turntable provided in the prior art. After eliminating the turntable, the problem of water or residue at the bottom of the cavity affecting or damaging the turntable is naturally avoided. At the same time, the microwave exit area is arranged on the top wall of the top of the cavity, which naturally avoids the water or residue at the bottom of the cavity affecting or damaging the microwave inlet or microwave component at the bottom of the cavity. In addition, since the microwave exit area is arranged on the top wall of the cavity, when the microwave steaming and baking cooking device of the embodiment of the present application is used, when the baking pan or grill is placed on both sides of the cavity, it naturally overcomes the problem of microwave transmission efficiency being blocked or reflected by the baking pan or grill when the microwave is emitted from the side.

[0064] The first heating element 400 is disposed in the heating zone 112, which is disposed on the top wall 110 and outside the microwave exit zone 111. The first heating element 400 heats the items in the cavity by heat radiation. Preferably, the first heating elements 400 are evenly arranged in the heating zone.

[0065] In some specific embodiments, the heating zone 112 is arranged around the microwave exit zone 111. With such an arrangement, microwaves can be emitted from the middle of the top to heat the food. The first heating element is arranged around the microwave exit zone of the top wall to heat the food in the heating cavity by thermal radiation, and the thermal radiation is relatively uniform, the area is also large, and the heating effect is good. Specifically, when microwaves are emitted from the microwave exit zone in the middle of the top, a part of the microwaves directly contact and heat the top of the food placed in the heating cavity, another part of the microwaves are reflected by the side walls of the cavity and contact and heat the side of the food placed in the heating cavity, and another part of the microwaves are reflected by the bottom wall of the cavity and contact and heat the bottom surface of the food, so that the food is evenly heated. It should be noted that the above is only an explanation of the microwave propagation path, and does not represent a limitation on the microwave propagation path. In actual use, the microwave propagation path is more complex and changeable. In addition, the heating zone 112 is arranged around the microwave emission zone 111. When the first heating element 400 is arranged in the heating zone, the first heating element heats and radiates heat downward toward the heating cavity, forming a heat radiation zone surrounding the heating zone. The food placed in the heating cavity is generally placed in the middle of the heating cavity, which is just surrounded by the heat radiation zone, and the heating is more uniform. It should be noted that the above exemplary description of the heat radiation method of the first heating element does not represent a limitation on the heat radiation method of the first heating element. For example, when the first heating element is used in combination with the convection system of the embodiment of the present application for heating, a forced hot air convection cycle will be formed in the heating zone, and the food will be heated by the forced hot air circulation.

[0066] Preferably, in some preferred embodiments, there is a first distance D from the center of the top wall to the edge of the microwave exit zone 111, and there is a second distance d from the edge of the microwave exit zone 111 to the edge of the top wall, and D / d=a, where a ranges from 0.5 to 2. For example, D is 1, d is 2; or D is 1, d is 1; or D is 2, d is 1. Preferably, in the embodiment of the present application, the first distance D is equal to the second distance d; such a setting can ensure that the microwave exit zone is within a preferred size range, thereby ensuring that the microwave can reach all angles of the heating cavity with a shorter path when it is emitted from the exit zone; at the same time, a relatively sufficient area is reserved for the heating zone, and the heating zone is arranged around the microwave exit zone. The first heating element arranged in the heating zone generates heat, and can radiate heat downward from all sides of the top wall toward the heating cavity, so that the heat can be quickly diffused to all corners of the heating cavity.

[0067] In some preferred embodiments, the first heating element 400 includes at least one heating tube 410, and a portion of the heating tube 410 is bent to form a microwave emission port 420; the microwave emission port corresponds to the position of the microwave outlet port, so as to allow the microwave emitted from the microwave outlet port to pass through, and the microwave will not be blocked or reflected by the heating tube, which affects the microwave conduction efficiency. Specifically, the first heating element includes at least two heating tubes, one of which is partially bent to form the microwave emission port, and the remaining portion is bent and arranged in the heating zone; the other heating tube is bent and arranged in the heating zone. The first heating element can also be other heat sources, such as heating wires, heating plates, heating films, etc.

[0068] In the embodiment of the present application, the cavity further has a bottom wall 150, and the bottom wall 150 is located on a different side of the cavity from the first inner wall and the top wall 110; an evaporation area 151 is provided on the bottom wall, and the evaporation area is provided with a third heating element for evaporating the liquid in the evaporation area. The third heating element can be a heating tube installed at the bottom of the evaporation area, and of course, it can also be other heat sources, such as a heating wire, a heating plate, a heating film, etc.

The inner heat insulation board 210 divides the cavity into a heating cavity 162 and an inner heat insulation cavity 161, and the inner heat insulation cavity is formed between the inner heat insulation board 210 and the rear wall 140. Figure 6As shown, the heating chamber is located at the front of the cavity, and the inner insulation chamber is located at the rear of the cavity.

[0072] The inner heat insulation board is provided with two groups of air inlets 211 and air outlets 212. The two groups of fan blade components are partially placed in the inner heat insulation cavity, and one group of fan blade components corresponds to one group of air inlets and air outlets; when the two groups of fan blade components work at the same time, two circulating airflows are formed. As can be seen from the figure, each circulating airflow can also include two small circulating airflows.

[0073] Preferably, two groups of air inlets 211 are symmetrically arranged on the inner heat insulation board, and two groups of air outlets are arranged around the inner heat insulation board. When one group of fan blade assemblies is working, the gas in the heating chamber is sucked into the inner heat insulation chamber from the air inlet corresponding to the group of fan blade assemblies, and then diffused around the fan blades and sent to the heating chamber from the air outlet corresponding to the group of fan blade assemblies, forming a circulating airflow; when the two groups of fan blade assemblies are working at the same time, two circulating airflows are formed.

[0074] In some embodiments, the microwave oven cooking device of this embodiment further includes a second heating element 230, which is a group of heating tubes arranged around the two fan blade assemblies.
