Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a microwave oven. Background Art

[0002] A microwave oven is a household appliance that can heat food using microwaves, steam, or bake.

[0003] For example, Figure 1 As shown, in the Chinese patent document with publication number CN217959649U, a microwave oven is disclosed, which includes a cavity 1', a waveguide box 2', and a magnetron 3'. The waveguide box 2' and the magnetron 3' are placed on the cavity 1'. The arrangement of the waveguide box 2' and the magnetron assembly 3' makes the upper part of the door panel of the microwave oven too large to be opened, which is not beautiful, and the volume ratio of the microwave oven is low. Utility Model Content

[0004] The utility model aims to provide a microwave oven, aiming to solve the above problems of unsightly appearance and low volume ratio.

[0005] In order to achieve the above object, the present application provides a microwave oven, comprising:

[0006] The heating cavity comprises a top plate and a back plate, wherein the connection between the top plate and the back plate is concave to form a receiving space, and a microwave inlet is arranged on the top plate;

[0007] A microwave assembly, the microwave assembly comprising a microwave generator and a waveguide box;

[0008] Wherein, the microwave component is at least partially located in the accommodating space, and the waveguide box connects the microwave generator and the microwave inlet.

[0009] Compared with the prior art, the present application provides a heating cavity, and the connection between the top plate and the back plate of the heating cavity is concave to form a storage space. Since the volume of the microwave component is relatively large, the microwave component is partially arranged in the storage space, which reduces the space occupied by the microwave component above the heating cavity, so that the height of the upper part of the microwave oven door panel that cannot be opened is shortened, which is more beautiful. And under the premise of maintaining the inconvenient external dimensions of the microwave oven, the space occupied above the heating cavity is reduced, and the space of the microwave oven is further converted into the volume of the heating cavity, thereby improving the volume ratio of the microwave oven. At the same time, the waveguide box is connected to the microwave inlet of the top plate, so that the microwave enters the heating cavity from the top, which provides the possibility for microwave conduction and microwave heating.

[0010] In some embodiments, the vertical cross-section of the accommodating space is stepped, including a first step formed by the back plate being recessed toward the heating cavity, and a second step formed by the top plate being recessed toward the heating cavity;

[0011] The microwave generator is at least partially located on the first step of the back plate, and the waveguide box is at least partially located on the second step of the top plate.

[0012] By setting the vertical cross-section of the accommodating space to be stepped, and the back plate is concave into the heating cavity to form a first step, and the top plate is concave into the heating cavity to form a second step, the microwave generator is at least partially located on the first step of the back plate, and the waveguide box is at least partially located on the second step of the top plate, so that the accommodating space formed by the heating cavity fits with the microwave component, the space can be effectively utilized, and the volume ratio of the whole machine is improved.

[0013] In some embodiments, the waveguide box includes a first section and a second section, the first section and the second section are arranged at an angle; the first section and the second section are connected at their ends to the microwave generator and the second section respectively; the first section and the second section are connected at their ends to the microwave inlet respectively;

[0014] The first section is at least partially located on the second step of the accommodating space, and the second section is located above the top plate.

[0015] By dividing the waveguide box into a first section and a second section, the first section and the second section are arranged at an angle, and the head and tail of the first section are respectively connected to the microwave generator and the second section; the head and tail of the second section are respectively connected to the first section and the microwave inlet, it is possible for the microwave to be transmitted from the microwave generator located in the accommodating cavity to the second section of the waveguide box located above the top rod. At the same time, the first section is at least partially located on the second step of the accommodating space, and the second section is located above the top plate, which further makes the waveguide box fit with the heating cavity, effectively utilizes the space, and improves the volume ratio of the whole machine.

[0016] In some embodiments, the waveguide box includes a first section and a second section, wherein the first section is arranged at an angle to the second section;

[0017] The first section is located in the accommodation space, and the head and tail of the first section are respectively connected to the microwave generator and the second section;

[0018] The second section is located above the top plate and is arranged parallel to the top plate. The head and tail of the second section are respectively connected to the first section and the microwave inlet.

[0019] By dividing the waveguide box into a first section and a second section, the first section is tilted relative to the microwave generator, and the first section and the second section are arranged at an angle, which provides the possibility for microwaves to be transmitted from the microwave generator located in the accommodating cavity to the second section of the waveguide box located above the top rod. By arranging the second section parallel to the top plate, the second section of the waveguide box is attached to the top plate, which further makes the structure compact and improves the volume ratio.

[0020] In some embodiments, the second section is flat.

[0021] By setting the second section to be flat, the height occupied by the waveguide box is reduced, and the height of the space above the heating cavity is further reduced, so that the upper part of the door panel is shortened.

[0022] In some embodiments, the top of the microwave generator and the top of the waveguide box are located at the same horizontal plane.

[0023] By locating the top of the microwave generator and the top of the waveguide box at the same horizontal plane, no unusable space is generated in the microwave steam oven due to inconsistent heights of the microwave generator and the waveguide box, further making the structure of the microwave steam oven compact and improving the volume ratio of the whole machine.

[0024] In some embodiments, the outer surface of the top plate includes a raised portion, and the raised portion is formed by the outer surface of the top plate protruding outward.

[0025] By providing the raised portion of the top plate, the top plate can fill the unused gap on the top of the microwave oven, thereby effectively utilizing the space, increasing the volume of the heating cavity that can be used to place food, and improving the volume ratio of the entire machine.

[0026] In any of the above embodiments, the microwave oven comprises: a baking component, which is arranged in the heating cavity and is used to bake and heat the heating cavity;

[0027] A convection component, which is arranged in the heating cavity and is used to form a circulating hot air flow in the heating cavity;

[0028] The steam component is arranged in the heating cavity and is used for performing steam heating on the heating cavity.

[0029] By setting the baking component, convection component and steam component, it is possible for the microwave oven to perform baking, circulating hot air heating and steam heating.

[0030] In some embodiments, the convection assembly is disposed on a back plate.

[0031] Since the fan of the convection component is relatively large, it is set on the back plate, which can effectively utilize the unused space of the microwave component on the back plate, making the microwave oven structure more compact and the volume ratio larger; at the same time, it can also only change the depth of the heating cavity while keeping the total volume unchanged, without affecting the height and width of the heating cavity, making the door panel larger and more beautiful.

[0047] The microwave oven is a three-in-one kitchen appliance that combines microwave heating, steam heating, and baking heating. The microwave oven can use the above three heating methods at the same time. However, due to the large volume of the microwave component, after the microwave component is installed in the microwave oven, the volume of the whole machine remains unchanged, and the microwave component occupies a large volume, which makes the volume of the heating cavity for heating food smaller, and the overall volume ratio is low. The door panel of the microwave oven is divided into two parts, the upper part of the door panel is a control panel or handle that cannot be opened, which can hide internal components such as the microwave component; the lower part of the door panel is a door that can be opened. After the lower door is opened, the user can directly observe the heating cavity. After the microwave component is installed, because the microwave component occupies a large volume, the user observes from the door panel that the area of ​​the upper part of the door panel that cannot be opened is too large and unsightly.

[0048] like Figure 1 As shown, for example, a microwave oven includes a cavity 1', a waveguide box 2', and a magnetron 3'. An installation space is set between the cavity 1' and the housing, and the waveguide box 2' and the magnetron 3' are set in the installation space. Specifically, the waveguide box 2' and the magnetron assembly 3' are installed above the cavity 1'. The magnetron assembly 3' occupies a large space of the microwave oven, making the upper part of the door panel of the cavity 1' that cannot be opened larger, which is not beautiful, and the layout is not compact, and the idle space is large, so that the volume ratio of the microwave oven is low.

[0049] To this end, the present application provides a microwave oven, the structure of which can effectively improve the above-mentioned problems. Specific embodiments will be provided below for illustration.

[0050] Specifically, Figure 2As shown, a microwave oven comprises a heating cavity 1 and a microwave component 2.

[0051] like Figure 3 As shown, the heating cavity 1 includes a top plate 11 and a back plate 12, and the connection A between the top plate 11 and the back plate 12 is concave to form a storage space 13, and a microwave inlet 111 is provided on the top plate 11. Specifically, the heating cavity 1 is a hexahedral square box as a whole, which includes a top plate 11 and a bottom plate above and below, side plates on the left and right sides, and a door plate and a back plate 12 at the front and back. The top plate 11, the back plate 12, the side plates, etc. can be connected by welding, or fixed by screws, or fixed by riveting. Of course, the top plate 11, the back plate 12, etc. can also be integrally formed, and the entire heating cavity is directly die-cast as one. The top plate 11 and the back plate 12 are concave inward to form a storage space 13, and various components can be placed in the storage space 13. In this embodiment, the storage space 13 is located in the middle of the upper part of the back plate 12. Of course, in other embodiments, it can also be located on the left or right side of the upper part of the back plate 12.

[0052] The microwave assembly 2 includes a microwave generator 21 and a waveguide box 22. Specifically, the microwave generator 21 is a magnetron, and the microwave generating end of the magnetron is connected to the waveguide box 22. In order to transmit microwaves, the waveguide box 22 is designed to be bent. In order to make the structure more compact, the waveguide box 22 is flat. The microwave assembly 2 may also include a heat sink or a heat dissipation duct, which dissipates heat from the microwave generator 21 to prevent the microwave generator 21 from overheating.

[0053] The microwave component 2 is at least partially located in the accommodating space 13, and the waveguide box 22 connects the microwave generator 21 and the microwave inlet 111. Specifically, part of the top plate 11 and part of the back plate 12 form a continuous step, so that the heating cavity 1 is concave, the microwave generator 21 of the microwave component 2 is located on the step of the back plate 12, and the waveguide box 22 is located on the step of the top plate 11, that is, the microwave component 2 is located in the accommodating space 13, and the microwave component 2 and the heating cavity 1 as a whole are still a hexahedral square box. At the same time, the waveguide box 22 connects the microwave generator 21 and the microwave inlet 111, so that the microwave can enter the heating cavity 1 from the top plate 11 to achieve the effect of microwave heating. Figure 1 , 2 By comparison, it can be seen that the upper space of the microwave oven in this embodiment is significantly reduced, that is, the upper part of the door panel 14 becomes shorter, more beautiful, and more compact. In addition, under the premise of maintaining the external dimensions of the microwave oven, the space above the microwave oven becomes smaller, thereby improving the volume ratio of the microwave oven.

[0054] Preferably, the vertical cross-section of the accommodating space 13 is stepped, including a first step 121 formed by the back plate 12 being recessed toward the heating cavity 1, and a second step 112 formed by the top plate 11 being recessed toward the heating cavity 1. The microwave generator 21 is at least partially located on the first step 121 of the back plate 12, and the waveguide box 22 is at least partially located on the second step 112 of the top plate 11. Specifically, the microwave generator 21 is a magnetron, part of the magnetron is square, and part of the back plate 12 is designed in a stepped shape, that is, the back plate 12 has a first step 121, and the magnetron is placed exactly on the first step 121. Part of the waveguide box 22 is square, and part of the top plate 11 is designed in a stepped shape, and the waveguide box 22 is placed exactly on the second step 112.

[0055] Furthermore, the waveguide box 22 includes a first section 221 and a second section 222. The first section 221 and the second section 222 may be independent components connected together, or may be directly formed as one piece.

[0056] The first section 221 is located in the accommodation space 13 and is tilted relative to the microwave generator 21. Specifically, the first section 221 has a flat microwave channel, which is at an angle of 45 degrees to the microwave generator 21 and faces upward, so that the first section 221 can transport the microwaves generated by the microwave generator 21 to the second section 222 above the top plate 11.

[0057] Further, the first section 221 is at least partially located on the second step 112 of the accommodation space 13. Specifically, the first section 221 has a square protrusion, so that the first section 221 can be placed and engaged on the second step 112.

[0058] Among them, the second section 222 is located above the top plate 11. Specifically, the second section 222 can be directly installed on the top plate 11 by screws; or a fixing frame can be placed on the top plate 11, and the second section 222 is installed on the fixing frame, so that the second section 222 is not released from the top plate 11, is not easy to deform, and achieves a shock-absorbing effect.

[0059] Preferably, in order to prevent the waveguide box 22 from having an irregular shape that affects the utilization of space, the second section 222 is arranged parallel to the top plate 11.

[0060] Preferably, in order to further reduce the height of the waveguide box 22, the second section 222 is flat.

[0061] The first section 221 and the second section 222 are arranged at an angle; the first section 221 is connected to the microwave generator 21 and the second section 222 at its head and tail, respectively; the second section 222 is connected to the first section 221 and the microwave inlet 111 at its head and tail. Specifically, the first section 221 and the second section 222 intersect at 45°. The microwaves emitted horizontally by the microwave generator 21 are reflected by the first section 221, and the direction of the microwaves is inclined 45° to the horizontal direction and faces upward; then, the microwaves are reflected by the second section 222, and the direction of the microwaves becomes horizontal, and enter the heating cavity 1 from the microwave inlet 111 along the second section 222.

[0062] Preferably, the top of the microwave generator 21 and the top of the waveguide box 22 are located in the same horizontal plane. Specifically, the top of the microwave generator 21 is a horizontal plane, and the top of the waveguide box 22 is also a horizontal plane. The two are located in the same horizontal plane, which can effectively reduce the space waste caused by the irregular shape. For example, the top of the microwave component 2 is a horizontal plane as a whole, so that the shell of the microwave oven can be directly covered on the horizontal plane, and the structure is more compact.

[0063] Preferably, the outer surface of the top plate 11 of the heating cavity 1 includes a raised portion 113, which is formed by protruding outward from the outer surface of the top plate 11. Specifically, the raised portion 113 is designed to be in a shape that matches the waveguide box 22. For example, the waveguide box has a square cross section, and the raised portion 113 is also designed to be square in cross section. Since the waveguide box 22 needs to transmit microwaves, the waveguide box 22 is designed according to the path of microwave transmission, so that the shape of the waveguide box 22 is relatively fixed, and all are in a broken line shape. The raised portion 113 can raise the horizontal position of the waveguide box 22, so that the horizontal position of the microwave generator 21 fixedly connected to the waveguide box 22 is also raised, so that the space above the waveguide box 22 is reduced, and the space of the heating cavity 1 becomes larger, that is, the upper height of the door panel 14 can be effectively reduced. At the same time, the raised portion 113 can also be arranged around the waveguide box 22, so that the raised portion 113 converts the unused space above the heating cavity 1 into the internal space of the heating cavity 1, thereby making the volume of the heating cavity larger.

[0064] Preferably, the microwave inlet 111 is located at the center of the top plate 11. Specifically, the microwave inlet 111 located at the center of the top plate 11 can emit microwaves from above to the food, covering a larger and more uniform area, avoiding the phenomenon of uneven heating of food due to microwaves emitted from the side or bottom.

[0065] like Figure 4As shown, preferably, the microwave assembly 2 also includes a microwave stirrer 23, which is located at the microwave inlet 111. Specifically, the microwave stirrer 23 includes a motor 231 and a stirring blade 232. The motor is located in the waveguide box, and the motor 231 has a motor shaft, and the motor shaft is connected to the stirring blade 232, and the stirring blade 232 extends into the heating cavity 1 through the microwave inlet 111 to facilitate stirring the microwave entering the heating cavity 1 from the waveguide box 22. A microwave penetration plate is also provided below the stirring blade 232, so that microwaves can penetrate, but air and steam cannot pass through, so as to prevent water vapor in the heating cavity from entering the microwave assembly 2 through the microwave inlet 111, thereby avoiding affecting the microwave assembly 2.

[0066] like Figure 5 As shown, preferably, the microwave oven further includes a baking component 3, a convection component 4, and a steam component 5.

[0067] The baking component 3 is arranged in the heating cavity to bake and heat the heating cavity. Specifically, the baking component 3 may include a heating tube, which is arranged on the top plate, the back plate and the bottom plate of the heating cavity 1 to bake and heat the heating cavity 1.

[0068] The convection assembly 4 is arranged in the heating cavity 1 to form a circulating hot air flow in the heating cavity 1. The convection assembly 4 includes a fan, which can form a circulating hot air flow in the heating cavity 1, so that the hot air in the heating cavity 1 circulates and heats the food. Of course, a heating pipe can also be arranged next to the fan to make the effect of circulating hot air better.

[0069] Preferably, the convection assembly 4 is arranged on the back plate 12. Specifically, the convection assembly 4 has a fan, which occupies a large volume and is arranged on the back plate 12. Although the depth of the accommodating space 1 is reduced, the length and height of the heating cavity 1 can be ensured, making it more beautiful when observed from the door body.

[0070] The steam component 5 is arranged in the heating cavity 1 to steam heat the heating cavity 1. Specifically, the steam component 5 includes a steam generator and a water tank. The steam generator converts water in the water tank into steam, and transports it to the heating cavity from the steam hole to steam heat the food.
