[0036] In the prior art, a microwave oven / steamer / bake combination includes a housing, a magnetron, an antenna, and a stirring motor. The housing includes a cooking chamber and a mounting chamber. The magnetron, stirring motor, and other related electrical components are located within the mounting chamber. The antenna is located at the top of the cooking chamber and connected to the stirring motor. When the microwave oven / steamer / bake combination is in operation, the stirring motor drives the antenna to rotate. The microwave output waveguide generated by the magnetron couples with the antenna, allowing the microwaves to radiate into the chamber through the antenna to heat the food. However, the magnetron's microwave power, frequency, and phase are difficult to adjust, resulting in poor cooking results when combined with a steam oven / steamer combination.

[0037] To address the above-mentioned problems, the present application provides a cooking device comprising a microwave solid-state source and at least two antenna units. The microwave solid-state source has at least two microwave output ports. The at least two antenna units are respectively disposed on different sides of the outer periphery of the microwave solid-state source and connected to the corresponding microwave output ports via cables. The microwave solid-state source is configured to generate microwaves, which are transmitted via cables to the at least two antenna units via the microwave output ports. The microwaves are then radiated into a cooking cavity via the at least two antenna units to provide cooking energy for food within the cooking cavity. Thus, on the one hand, radiating microwaves into the cooking cavity via the at least two antenna units can improve the uniformity of the microwaves within the cooking cavity. On the other hand, the microwaves generated by the microwave solid-state source can be adjusted to adjust parameters such as microwave frequency, phase, and power to improve the cooking effect when combined with functions such as steaming and baking. Furthermore, the at least two microwave output ports are disposed on different sides of the microwave solid-state source and connected to the antenna units on the corresponding sides via cables to prevent signal interference and loss between the cables.

[0038] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] The present application provides a cooking device, including but not limited to a microwave oven, steamer, and oven. The microwave oven is a kitchen cooking device that integrates multiple functions such as a microwave oven, steamer, and oven. The following description will take the microwave oven as an example.

[0040] Please refer to Figure 1 and Figure 2 As shown, the cooking device 100 provided in an embodiment of the present application includes a device body 110, and the device body 110 has a cooking cavity 111. The cooking cavity 111 is used to place food to be cooked. When the cooking device 100 is running, the food in the cooking cavity 111 can be heated, steamed, baked, etc.

[0041] In some embodiments, please refer to Figure 1 As shown, the cooking device 100 also includes a microwave solid-state source 120, which is a solid-state active device for generating microwave signals. The microwave solid-state source 120 has at least two microwave output ports 121 to facilitate the transmission of the generated microwave signals through the microwave output ports 121. The microwave power, frequency and phase of the microwave solid-state source 120 can be adjusted to facilitate combination with functions such as steaming and baking, thereby improving the cooking effect.

[0042] In some embodiments, at least two microwave output ports 121 may be disposed on different sides of the microwave solid-state source 120. For example, the at least two microwave output ports 121 may be located on opposite sides, adjacent sides, etc. of the microwave solid-state source 120, as long as the at least two microwave output ports 121 are located on different sides of the microwave solid-state source 120. In this way, mutual interference of microwave signals between the at least two microwave output ports 121 may be avoided.

[0043] For example, in Figure 1 In the figure, the outline shape of the microwave solid-state source 120 is a rectangular or approximately rectangular structure. The microwave solid-state source 120 has two microwave output ports 121. The two microwave output ports 121 are symmetrically arranged on opposite sides of the microwave solid-state source 120 to avoid mutual interference of microwave signals between the two microwave output ports 121.

[0044] In some embodiments, please refer to Figure 1 As shown, the cooking device 100 also includes at least two antenna units 130, which are arranged on the outer peripheral side of the microwave solid-state source 120 and are arranged one-to-one corresponding to at least two microwave output ports 121 of the microwave solid-state source 120, wherein one antenna unit 130 is connected to one microwave output port 121 through a cable 140, so that the microwave signal generated by the microwave solid-state source 120 is transmitted to the antenna unit 130 via the microwave output port 121 and the cable 140, and the antenna unit 130 is used to radiate the microwave signal generated by the microwave solid-state source 120 into the cooking cavity 111 to provide cooking energy for the food to be cooked in the cooking cavity 111.

[0045] In an embodiment of the present application, at least two antenna units 130 are provided to radiate the microwave signal generated by the microwave solid-state source 120 into the cooking cavity 111. In this way, the radiation area of the antenna unit 130 in the cooking cavity 111 can be increased, and the uniformity of the microwave in the cooking cavity 111 can be improved, thereby improving the cooking effect of the cooking device 100.

[0046] In some embodiments, as Figure 1 and Figure 2 As shown in the figure, the antenna unit 130 includes an antenna connector 131 and an antenna bracket 132 connected to the antenna connector 131. The antenna connector 131 is connected to the microwave output port 121 via a cable 140. The antenna bracket 132 is arranged in the cooking cavity 111 and connected to the antenna connector. In this way, the microwave signal generated by the microwave solid-state source 120 is transmitted to the antenna bracket 132 in sequence through the microwave output port 121, the cable 140 and the antenna connector 131. The antenna bracket 132 radiates the received microwave signal into the cooking cavity 111 to provide cooking energy for the food to be cooked in the cooking cavity 111.

[0047] In some embodiments, the antenna connector 131 and the corresponding microwave output port 121 are located on the same straight line. Thus, the antenna connector 131 and the corresponding microwave output port 121 can be connected via a coaxial cable 140 to save the connection length of the cable 140 and thus improve the compactness of the structure.

[0048] Of course, the antenna connector 131 and the corresponding microwave output port 121 may not be located on the same straight line, and can be adaptively configured according to actual needs, and no specific limitation is made here.

[0049] It can be understood that the antenna bracket 132 is made of a material that has the function of radiating microwave signals. For example, the antenna bracket 132 can be a rod-shaped structure, and the rod-shaped structure can be a straight line, a broken line, a curve, a ring, etc., so as to increase the radiation area of the antenna bracket 132, improve the uniformity of microwaves in the cooking cavity 111, and thus improve the cooking effect.

[0050] In some embodiments, as Figure 1 and Figure 2 As shown in the figure, there are two antenna units 130, and the two antenna units 130 are symmetrically arranged on opposite sides of the microwave solid-state source 120. In this way, the microwave solid-state source 120 is arranged between the two antenna connectors 131, and the corresponding microwave output ports 121 on the microwave solid-state source 120 are connected through a cable 140 to transmit the microwave signal generated by the microwave solid-state source 120 to the antenna bracket 132, so as to be radiated into the cooking cavity 111 through the antenna bracket 132.

[0051] In the embodiment of the present application, by arranging two antenna units 130 on opposite sides of the microwave solid-state source 120, and connecting the antenna unit 130 and the microwave output port 121 located on the same side of the microwave solid-state source 120 through the cable 140, the mutual interference between the cables 140 can be reduced, and the length of the cable 140 can be shortened, thereby reducing the loss of the cable 140.

[0052] Thus, in the embodiment of the present application, a microwave solid-state source 120 and at least two antenna units 130 are designed. The microwave solid-state source 120 has at least two microwave output ports 121. The at least two antenna units 130 are respectively arranged on different sides of the periphery of the microwave solid-state source 120 and connected to the corresponding microwave output ports 121 through cables 140. The microwave solid-state source 120 is used to generate microwaves, and transmit them to the at least two antenna units 130 through the microwave output ports 121 through the cables 140, so that the microwaves are radiated to the cooking cavity 111 through the at least two antenna units 130 to control the cooking cavity 111. The cooking cavity 111 is provided with cooking energy for the food therein. Thus, on the one hand, microwaves are radiated into the cooking cavity 111 by at least two antenna units 130, so that the uniformity of the microwaves in the cooking cavity 111 can be improved. On the other hand, microwaves are generated by the microwave solid-state source 120, so that parameters such as microwave frequency, phase and power can be adjusted to improve the cooking effect when combined with functions such as steaming and baking. On the other hand, at least two microwave output ports 121 are arranged on different sides of the microwave solid-state source 120 and connected to the antenna units 130 on the corresponding sides through cables 140 to prevent signal interference and loss between the cables 140.

[0053] In order to improve the overall aesthetics and safety and reliability of the cooking device 100, in some embodiments, the device body 110 further includes a mounting cavity 112, for example, Figure 1As shown in FIG, the device body 110 includes a rear side panel 117, a left side panel 118, a right side panel 119 and a glass panel 116 located at the front side, which are arranged at the top of the cooking cavity 111. The rear side panel 117, the left side panel 118, the glass panel 116 and the right side panel 119 are connected end to end to form a mounting cavity 112 with a rectangular structure. The left side panel 118 and the right side panel 119 are arranged opposite to each other, and the rear side panel 117 and the glass panel 116 are arranged opposite to each other. The mounting cavity 112 is arranged at the top of the cooking cavity 111, and the microwave solid-state source 120 and the antenna connector 131 are arranged in the mounting cavity 112. 12, the antenna bracket 132 is located in the cooking cavity 111 and is arranged on the top of the cooking cavity 111, so that the radiated microwaves cover the entire cooking cavity 111. By arranging the microwave solid-state source 120 and the antenna connector 131 in the installation cavity 112, a top cover can be provided on the top of the installation cavity 112, so that the components installed in the installation cavity 112 are not exposed to the outside, thereby improving the overall aesthetics of the cooking device 100, and also protecting the microwave solid-state source 120, the antenna connector 131 and the cable 140, thereby improving the overall safety and reliability of the cooking device 100.

[0054] Please refer to Figure 3 As shown, the installation cavity 112 also has an air duct 113, and the microwave solid-state source 120 and the antenna connector 131 are both arranged in the air duct 113. The side wall of the device body 110 has an air inlet and an air outlet 115 connected to the air duct 113. In this way, the airflow entering the air duct 113 through the air inlet can carry the heat of the microwave solid-state source 120 and the antenna connector 131 and be discharged to the outside of the installation cavity 112 (i.e., the outside of the cooking device 100) through the air outlet 115, so that the components such as the microwave solid-state source 120 and the antenna connector 131 wrapped in the air duct 113 can be cooled to avoid the temperature of the components such as the microwave solid-state source 120 and the antenna connector 131 being too high and affecting their working reliability.

[0055] In some embodiments, except for the contact portion of the cable 140 with the antenna connector 131, the other portions of the cable 140 are located outside the air duct 113. In this way, the heat in the air duct 113 can be prevented from damaging the cable 140, thereby extending the service life of the cable 140. In addition, arranging the cable 140 outside the air duct 113 can reduce the cross-sectional size of the air duct, increase the flow rate of the air flow in the air duct, and improve the heat dissipation efficiency.

[0056] In some embodiments, as Figure 3As shown in the figure, the cooking device 100 also includes a fan 150, which is arranged in the installation cavity 112 and docked with the air inlet of the air duct 113. In this way, when the fan 150 is in operation, it can provide driving force for the airflow in the air duct 113 to increase the flow rate of the airflow in the air duct 113, so that the airflow can take away the heat generated by components such as the microwave solid-state source 120 and the antenna connector 131 in the air duct 113, thereby improving the safety, reliability and working reliability of each component in the installation cavity 112.

[0057] The fan 150 includes but is not limited to a double-headed fan 150 , and is not limited here as long as it can provide driving force for the airflow in the air duct 113 and increase the flow velocity of the airflow in the air duct 113 .

[0058] In some embodiments, the side wall of the installation cavity 112 has an air inlet hole connected to the outside world. The natural cold air entering the installation cavity 112 is sucked into the air duct 113 by the fan 150 to form a flowing airflow with a certain intensity in the air duct 113. The airflow through the flow channel takes away the heat generated by components such as the microwave solid-state source 120 and the antenna connector 131 located in the air duct 113, so as to achieve the purpose of heat dissipation and cooling of various components in the air duct 113.

[0059] In some embodiments, please refer to Figure 3 As shown, the air duct 113 includes a first sub-air duct 1131 and at least two second sub-air ducts 1132 that are interconnected, and the at least two second sub-air ducts 1132 are respectively located on the outer peripheral side of the first sub-air duct 1131, the microwave solid-state source 120 is located in the first sub-air duct 1131, and at least two antenna connectors 131 are respectively located in at least two second sub-air ducts 1132, wherein one antenna connector 131 is located in one second sub-air duct 1132. It can be understood that by setting the air duct 113 as multiple sub-air ducts, the air flow entering the air duct 113 can be guided through each sub-air duct, and each component can be placed in a different sub-air duct. In this way, the heat dissipation efficiency of each component can be improved, and the influence of the heat generated by each component on other components can be avoided, thereby improving the heat dissipation efficiency.

[0060] For example, in Figure 3In the figure, the air duct 113 includes a first sub-air duct 1131 and two second sub-air ducts 1132, and the two second sub-air ducts 1132 are respectively arranged on opposite sides of the first sub-air duct 1131, and the microwave solid-state source 120 is arranged in the first sub-air duct 1131. The two antenna connectors 131 arranged on opposite sides of the microwave solid-state source 120 are respectively located in the two opposite second sub-air ducts 1132. In this way, the airflow entering the air duct 113 enters the first sub-air duct 1131 and the two second sub-air ducts 1132 respectively, so as to guide the airflow entering the air duct 113 through the first sub-air duct 1131 and the two second sub-air ducts 1132. In this way, the airflow entering the air duct 113 is concentrated in the first sub-air duct 1131 and the two second sub-air ducts 1132 for flow, thereby improving the heat dissipation efficiency of the microwave solid-state source 120 and the two antenna connectors 131.

[0061] It should be noted that the first sub-duct 1131 and the two second sub-ducts 1132 can be independent of each other or interconnected, as long as they can guide the airflow in the duct 113 and improve the heat dissipation efficiency, and there is no limitation here.

[0062] Please refer to Figure 4 As shown, the top of the first sub-duct 1131 is interconnected with the tops of at least two second sub-ducts 1132. Since the height of the microwave solid-state source 120 is greater than the height of the antenna connector 131, the airflow in the flow channel of the air duct 113 can exchange heat with the microwave solid-state source 120 at a high level, thereby facilitating heat dissipation of the microwave solid-state source 120. However, the height of the antenna connector 131 is relatively low, and the heat exchange between the antenna connector 131 and the airflow in the air duct 113 is relatively poor. To improve the efficiency and effect of heat exchange between the antenna connector 131 and the airflow in the second sub-duct 1132, in this embodiment of the present application, the top of the first sub-duct 1131 is higher than the tops of each second sub-duct 1132. In this way, wind pressure can be generated in each second sub-duct 1132, thereby facilitating heat exchange between the antenna connector 131 in the second sub-duct 1132 and the airflow in the air duct 113, thereby improving the heat exchange efficiency and effect, so that the flowing airflow can carry the heat of the antenna connector 131 out of the cooking device 100.

[0063] In order to further increase the heat exchange effect and efficiency in the air duct 113, in some embodiments, please refer to Figure 5As shown, the cross-sectional size of the first sub-duct 1131 gradually decreases along the direction from the air inlet to the air outlet 115. For example, the height of the first sub-duct 1131 gradually decreases along the direction from the air inlet to the air outlet 115, that is, the height of the first sub-duct 1131 near the air outlet 115 is smaller than the height near the air inlet. In this way, the flow velocity at the air outlet 115 in the first sub-duct 1131 can be reduced, and the wind pressure in the first sub-duct 1131 can be increased, so that the natural cold air flow in the duct 113 can fully exchange heat with the heat generated by the microwave solid-state source 120, so that the heat of the microwave solid-state source 120 is carried by the air flow and discharged to the external environment through the air outlet 115, so as to dissipate heat and cool the microwave solid-state source 120, thereby improving the working reliability of the microwave solid-state source 120.

[0064] For example, in Figure 5 In the figure, the height of the first sub-duct 1131 near the air outlet 115 is represented by H1, and the height of the first sub-duct 1131 near the air inlet is represented by H2. Obviously, the height of H1 is much smaller than the height of H2.

[0065] Similarly, if Figure 4 As shown in , the cross-sectional dimensions of each second sub-duct 1132 gradually decrease along the direction from the air inlet to the air outlet 115. Exemplarily, the height of the second sub-duct 1132 gradually decreases along the direction from the air inlet to the air outlet 115, i.e., the height of the second sub-duct 1132 at one end near the air outlet 115 is less than the height at the end near the air inlet. This reduces the flow rate at the air outlet 115 in the second sub-duct 1132 and increases the wind pressure in the second sub-duct 1132, allowing the natural cooling airflow in the duct 113 to fully exchange heat with the heat generated by the antenna connector 131 in the second sub-duct 1132. The heat from the antenna connector 131 is carried by the airflow and discharged to the external environment through the air outlet 115, thereby dissipating heat and cooling the antenna connector 131, thereby improving the operational reliability of the antenna connector 131.

[0066] For example, in Figure 4 In the figure, the height of the second sub-duct 1132 near the air outlet 115 is represented by H3, and the height of the first sub-duct 1131 near the air inlet is represented by H4. Obviously, the height of H3 is much smaller than the height of H4.

[0067] In addition, in order to further increase the heat carried by the air flow flowing in the air duct 113 to the various components in the air duct 113, in the embodiment of the present application, the air outlet end of the fan 150 is tightly connected to the air inlet of the air duct 113 to ensure that all the wind blown out by the air outlet end of the fan 150 enters the air duct 113, so as to dissipate the heat of the microwave solid-state source 120 and the antenna connector 131 in the air duct 113, and discharge the heat to the outside of the cooking device 100 through the air outlet 115.

[0068] In some embodiments, the air outlet 115 can be a slender opening with a relatively small height, so that the air outlet rate can be reduced, the wind pressure in the air duct 113 can be increased, and the heat exchange effect in the air duct 113 can be improved; for example, the fan 150 can be arranged at a position near the rear side of the installation cavity 112, and the air outlet 115 is arranged on one side of the glass panel 116 on the front side, for example, at Figure 3 In the figure, the air outlet 115 is arranged on the lower side of the glass panel 116, and the air outlet 115 is an elongated opening with the same length as the glass panel 116. In this way, under the action of the fan 150, the air flow in the air duct 113 flows from the rear side to the front side of the cooking device 100, and is discharged from the elongated air outlet 115 on the front side of the cooking device 100, thereby achieving the purpose of heat dissipation and cooling in the installation cavity 112.

[0069] In summary, in the cooking device provided in the embodiment of the present application, microwave radiation is performed into the cooking cavity by at least two antenna units, so that the uniformity of the microwaves in the cooking cavity can be improved; in addition, microwaves are generated by a microwave solid-state source, so that parameters such as microwave frequency, phase and power can be adjusted to improve the cooking effect when combined with functions such as steaming and baking; and at least two microwave output ports are arranged on different sides of the microwave solid-state source and connected to the antenna units on the corresponding sides through cables to prevent signal interference and loss between the cables.
