Cooking appliances with microwave heating function

Abstract

The present invention relates to a cooking appliance with a microwave heating function, comprising a box, a first fan, a second fan, a variable frequency power supply and a magnetron. When the above-mentioned cooking appliance with a microwave heating function is working, on the one hand, the first fan draws air from the outside of the box through the side air inlet mesh and the bottom air inlet mesh, and blows it to the variable frequency power supply to dissipate heat for the variable frequency power supply. The large amount of air entering has a good heat dissipation effect on the variable frequency power supply. The second fan draws air from the outside of the box through the bottom air inlet mesh or the side air inlet mesh, and blows it to the magnetron to dissipate heat, thereby achieving a good heat dissipation effect for the magnetron. On the other hand, since the first fan is tilted relative to the bottom cover plate with the surface where its air inlet is located, the horizontal space occupied by the first fan can be reduced to a certain extent relative to the horizontal setting, thereby increasing the volume of the cooking cavity while reducing the heat dissipation effect.

Description

Technical Field

[0001] The invention relates to a cooking appliance, in particular to a cooking appliance with a microwave heating function. Background Art

[0002] Cooking appliances, especially cooking appliances with microwave heating function, such as microwave ovens with simple microwave heating function, microwave grills with heating tube grilling function, microwave steamers with steam heating function or microwave steamers and grills with three functions, are described below using microwave ovens as an example. Microwave ovens use magnetrons to generate high-frequency microwaves to heat food. The heat generated by the microwave oven itself mainly comes from the magnetron and the power supply. It is necessary to focus on the heat dissipation of these two components, otherwise it is easy to reduce the service life of the microwave oven. However, under the premise that the volume of the entire microwave oven is fixed, in order to increase the volume of the cooking cavity inside the microwave oven for placing food, it is necessary to reduce the space used to place other components, which will cause the heat dissipation space of these components to become smaller, thereby reducing the heat dissipation effect.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0025] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0027] In one embodiment, see Figures 1 to 3 , Figure 5A cooking appliance with a microwave heating function comprises: a box 10, a first fan 20, a second fan 30, a variable frequency power supply 40 and a magnetron 50. The box 10 comprises a shell 11 and a cooking cavity 12 arranged in the shell 11. The shell 11 comprises a first side cover plate 111, a rear cover plate 112 and a bottom cover plate 113. The first side cover plate 111 is connected to the rear cover plate 112, and the first side cover plate 111 and the rear cover plate 112 are both connected to the bottom cover plate 113. The first side cover plate 111 is close to the rear cover plate 112 and one of the corners of the bottom cover plate 113 and is provided with a side air inlet mesh 1111. The bottom cover plate 113 is close to the first side cover plate 111 and one of the corners of the rear cover plate 112 and the bottom cover plate 113 and is provided with a bottom air inlet mesh 1131. The first fan 20, the second fan 30, the variable frequency power supply 40 and the magnetron 50 are all arranged in the interval area between the rear wall of the cooking cavity 12 and the rear cover 112, the surface where the air inlet of the first fan 20 is located is inclined relative to the bottom cover 113, the surface where the air inlet of the first fan 20 is located faces the side air inlet mesh 1111 and the bottom air inlet mesh 1131, the surface where the air outlet of the first fan 20 is located faces the variable frequency power supply 40, the surface where the air inlet of the second fan 30 is located faces the bottom air inlet mesh 1131 or the side air inlet mesh 1111, and the surface where the air outlet of the second fan 30 is located faces the magnetron 50.

[0028] When the above-mentioned cooking appliance with microwave heating function is working, on the one hand, the first fan 20 draws air from the outside of the box 10 through the side air inlet mesh 1111 and the bottom air inlet mesh 1131, and blows it onto the variable frequency power supply 40 to dissipate heat for the variable frequency power supply 40. The large amount of air entering has a good heat dissipation effect on the variable frequency power supply 40. The second fan 30 draws air from the outside of the box 10 through the bottom air inlet mesh 1131 or the side air inlet mesh 1111, and blows it onto the magnetron 50 to dissipate heat, thereby achieving a good heat dissipation effect for the magnetron 50. On the other hand, since the first fan 20 is inclined relative to the bottom cover plate 113 with the surface where its air inlet is located, the horizontal space occupied by the first fan 20 can be reduced to a certain extent compared with the horizontal setting, thereby increasing the volume of the cooking cavity 12 while reducing the heat dissipation effect.

[0029] For further information, see Figures 1 to 3 and Figure 5The rear cover plate 112 is provided with a first rear air inlet mesh 1121 at one of the corners close to the first side cover plate 111 and the bottom cover plate 113. Thus, when the first fan 20 and the second fan 30 are working, the outside air of the box body 10 can also enter the box body 10 through the first rear air inlet mesh 1121, so as to increase the air volume and ensure a better heat dissipation effect.

[0030] For further information, see Figures 1 to 3 and Figure 5 , the first fan 20 is arranged above the second fan 30, and the angle A between the central axis 21 of the first fan 20 and the central axis 33 of the second fan 30 is less than 90°. It should be explained that the central axis 21 of the first fan 20 refers to the axis line of the surface perpendicular to the air inlet of the first fan 20, and the central axis 33 of the second fan 30 refers to the axis line of the surface perpendicular to the air inlet of the second fan 30. Specifically, the angle A between the central axis 21 of the first fan 20 and the central axis 33 of the second fan 30 is 30° to 40°, and preferably, A is 36°.

[0031] For further information, see Figures 2 to 6 The second fan 30 is a vortex fan, and both the upper surface and the lower surface of the vortex fan are provided with air inlets, and the lower surface of the vortex fan is connected to a first air guide cover 60. The top plate of the first air guide cover 60 is provided with a first ventilating port connected to the air inlet of the lower surface of the vortex fan, and the fan motor 31 of the vortex fan is arranged in the first air guide cover 60, and the first air guide cover 60 is provided in a part of the bottom air inlet mesh 1131, and the projection of the first fan 20 on the bottom cover plate 113 along the vertical direction is located in another part of the bottom air inlet mesh 1131. In this way, the first air guide cover 60 can divide the air entering the outer shell 11 from the bottom air inlet mesh 1131 into two independent and isolated winds, one of which is sucked in by the air inlet of the first fan 20, and the other is sucked in by the air inlet of the second fan 30. The two wind flows will not be confused and partially offset, thereby improving the utilization rate of cold air and ensuring the heat dissipation effect; in addition, the fan motor 31 of the vortex fan is arranged in the first air guide cover 60, and the wind flow entering the first air guide cover 60 has a heat dissipation effect on the fan motor 31, thereby improving the service life of the fan motor 31.

[0032] Specifically, see Figures 4 to 6The first air guide cover 60 includes two baffles 61 arranged at intervals and a mounting plate 62 connecting the two baffles 61. The first vent is formed on the mounting plate 62. The baffles 61 are respectively connected to the rear wall of the cooking cavity 12 and the rear cover 112. The fan motor 31 of the second fan 30 is arranged between the two baffles 61. The area between the two baffles 61 is opposite to the first rear air inlet mesh 1121 of the rear cover 112, and the outside air can enter between the two baffles 61 through the first rear air inlet mesh 1121. In addition, the mounting plate 62 is opposite to the bottom air inlet mesh 1131 of the bottom cover 113, and the outside air can also enter the first air guide cover 60 through the bottom air inlet mesh 1131.

[0033] In one embodiment, see Figures 4 to 6 , a ventilation gap 32 is provided between the first fan 20 and the second fan 30. In this way, a part of the wind enters the first air guide cover 60 through the bottom air inlet mesh 1131 and enters the air inlet on the lower surface of the second fan 30, and another part of the wind enters the housing 11 through the bottom air inlet mesh 1131 and the side air inlet mesh 1111, and enters the air inlet on the upper surface of the second fan 30 from the ventilation gap 32 between the first fan 20 and the second fan 30, thereby increasing the cold air intake of the second fan 30 and having a better heat dissipation effect.

[0034] In one embodiment, see Figures 4 to 6 The housing 41 of the variable frequency power supply 40 is provided with a first transverse ventilation channel, and the air outlet of the first fan 20 is connected to one of the ports of the first transverse ventilation channel. The outer wall of the other port of the first transverse ventilation channel is connected with a vertical partition 71 and a transverse partition 72. The vertical partition 71 and the transverse partition 72 are arranged on the periphery of the magnetron 50, and a second ventilation port 711 is provided on the vertical partition 71, and the air outlet of the second fan 30 is connected to the second ventilation port 711. In this way, on the one hand, the cold air sent out from the air outlet of the first fan 20 enters the first transverse ventilation channel to achieve better heat dissipation of the variable frequency power supply 40; on the other hand, under the action of the vertical partition 71 and the transverse partition 72, the two wind flows will not be chaotic and partially offset, thereby improving the utilization rate of the cold air and ensuring the heat dissipation effect.

[0035] For further information, see Figures 4 to 6 The horizontal partition 72 is also connected to the rear wall of the cooking cavity 12 and the rear cover 112. Similarly, the vertical partition 71 is also connected to the rear wall of the cooking cavity 12 and the rear cover 112.

[0036] In one embodiment, see Figures 4 to 6, the power connection connector 51 of the magnetron 50 is arranged adjacent to the transverse partition 72. The transverse partition 72 is provided with a third vent 721 corresponding to the power connection connector of the magnetron 50, and the third vent 721 is located on the transverse partition 72 on one side close to the vertical partition 71. In this way, after the cold air of the first fan 20 flows out through the first transverse ventilation channel, a part of the air flows into the space area where the magnetron 50 is located through the third vent 721, and when it flows into the area where the magnetron 50 is located from top to bottom, it fully exchanges heat with the magnetron 50, which can better reduce the temperature of the magnetron 50. In addition, it can avoid the generation of whirlwind in the area where the magnetron 50 is located.

[0037] In one embodiment, see Figures 4 to 6 The cooking appliance with microwave heating function further includes a second air guide cover 73. The heat sink housing 52 of the magnetron 50 is provided with a second transverse ventilation channel, the rear wall of the cooking cavity 12 is provided with a second rear air inlet mesh 121, and the second air guide cover 73 is covered by the second rear air inlet mesh 121. The second vent 711, the second transverse ventilation channel, and the air inlet of the second air guide cover 73 are connected in sequence. In this way, the cold air of the second fan 30 enters the second air guide cover 73 through the second vent 711 and the second transverse ventilation channel, and then enters the interior of the cooking cavity 12 through the second rear air inlet mesh 121.

[0038] In one embodiment, see Figures 4 to 6 The second air guide cover 73 is provided with a heat conducting edge 731 at the air inlet, and the heat conducting edge 731 is in contact with the magnetron 50. Specifically, the heat conducting edge 731 is in contact with the heat sink housing 52 of the magnetron 50, and the heat on the heat sink housing 52 of the magnetron 50 is transferred to the second air guide cover 73 by the heat conduction principle, thereby improving the heat dissipation effect of the magnetron 50.

[0039] In a specific embodiment, see Figures 4 to 6, the power connection connector 51 of the magnetron 50 is arranged adjacent to the transverse partition 72. The transverse partition 72 is provided with a third vent 721 corresponding to the power connection connector of the magnetron 50, and the third vent 721 is located on the transverse partition 72 on one side close to the vertical partition 71. The cooking appliance with microwave heating function also includes a second air guide cover 73, the radiator housing 52 of the magnetron 50 is provided with a second transverse ventilation channel, the rear wall of the cooking cavity 12 is provided with a second rear air inlet mesh 121, the second air guide cover 73 is covered by the second rear air inlet mesh 121, and the second vent 711, the second transverse ventilation channel, and the air inlet of the second air guide cover 73 are connected in sequence. In this way, when the second air guide 73 contains only the wind blown by the second fan 30, it is easy to generate vortex wind in the second air guide 73. After the third vent 721 is provided on the transverse partition 72, the wind blown by the first fan 20 can enter the area where the magnetron 50 is located from top to bottom through the third vent 721, and enter the second air guide 73, thereby helping to avoid the generation of vortex wind and having a better heat dissipation effect on the magnetron 50.

[0040] In one embodiment, see Figures 4 to 6 The cooking appliance with microwave heating function is a drawer-type microwave oven. The drawer-type microwave oven further includes a door body 80 and a container for placing cooking objects connected to the door body 80, and the door body 80 is connected to the side wall of the cooking cavity 12 through a slide rail. In addition, the box body 10 is provided with an opening, and the door body 80 is arranged corresponding to the opening.

[0041] For further information, see Figures 4 to 6 The housing 11 further includes a second side cover plate 114 and a top cover plate 115. The second side cover plate 114 is arranged opposite to the first side cover plate 111, and the second side cover plate 114 is respectively connected to the rear cover plate 112 and the bottom cover plate 113. The three sides of the top cover plate 115 are respectively connected to the first side cover plate 111, the rear cover plate 112 and the second side cover plate 114.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
