Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In an embodiment, referring to fig. 1, fig. 2, fig. 3 and fig. 5, a heat dissipation mechanism 110 includes: a hot air motor 111, a heat radiation fan 113 and an air guide cover 115. The hot air motor 111 is sleeved with a hot air cover 112. A fan cover 114 is sleeved on the heat radiation fan 113. The fan cover 114 and the hot air cover 112 are arranged oppositely at intervals, and an air outlet 1141 is arranged on the fan cover 114. An air guide channel 1151 is arranged in the air guide cover 115. The first end of the air guiding channel 1151 is communicated with the air outlet 1141, and the second end of the air guiding channel 1151 is communicated with the hot air cover 112.

In the heat radiation mechanism 110, an air guide cover 115 is provided between the hot air motor 111 and the heat radiation fan 113. When the cooking appliance 100 normally operates, the cool air generated by the heat dissipation fan 113 flows out of the air outlet 1141. Because the two ends of the air guide channel 1151 are respectively communicated with the air outlet 1141 and the hot air cover 112, the cold air flowing out of the air outlet 1141 can sequentially flow through the air guide channel and the hot air cover 112, so that the cold air in the heat dissipation fan 113 is stably blown to the hot air motor 111 under the guidance of the air guide cover 115, the working temperature of the hot air motor 111 is effectively reduced, the heat dissipation of the hot air motor 111 is realized, and the service life of the hot air motor 111 is prolonged. In addition, the heat dissipation mechanism 110 utilizes the wind scooper 115 to guide the hot wind motor 111, so that the stable cooling of the hot wind motor 111 is ensured, the structure in the cooking appliance 100 is kept relatively simple, and the phenomenon that the cooking appliance 100 is heavy as a whole due to the additional structure is avoided.

It should be noted that the air guide channel 1151 is communicated with the air outlet 1141 in a direct or indirect manner. Wherein, the direct communication mode is that the first end of the air guide channel 1151 is directly buckled on the air outlet 1141. The indirect communication mode is that an intermediate structure is communicated between the air guide channel 1151 and the air outlet 1141, for example: pipes, box-like structures, hood-like structures, etc. Similarly, the air guide channel 1151 can be in direct communication or indirect communication with the hot air hood 112. Such as: the direct communication between the wind guide channel 1151 and the hot air cover 112 is that the second end of the wind guide channel 1151 is directly communicated with the opening on the hot air cover 112. The indirect communication between the wind guiding channel 1151 and the hot air cover 112 may be a communication between the two, such as an intermediate pipe, an intermediate box-shaped structure, an intermediate cover-shaped structure, etc. Of course, the indirect communication between the wind guide channel 1151 and the hot air hood 112 can also be achieved by directly arranging the second end of the wind guide channel 1151 towards the opening on the hot air hood 112.

It should be noted that, in this embodiment, the specific shape of the air guide channel 1151 is not limited, and it is only necessary that the cool air can flow into the hot air cover 112 through the air guide channel 1151.

Further, referring to fig. 3, a side of the hot air hood 112 facing the air guiding hood 115 is provided with an air inlet 1121. The second end of the air guiding channel 1151 is disposed toward the air inlet 1121. Therefore, when the cold air in the air guiding channel 1151 flows out from the second end, the cold air stably flows into the air inlet 1121 of the hot air hood 112 under the action of the inertial flow velocity, so as to achieve effective heat dissipation and cooling of the heat dissipation fan 113.

The power cover 117 is used to flow at least a portion of the air flowing out of the air outlet 1141 to the heat sink 1181. When the cold air flows into the power supply cover 117, the cold air flows onto the heat sink 1181 on the magnetron 118 in addition to the power supply 116 under the guidance of the power supply cover 117, so as to dissipate the heat of the magnetron 118.

It should be noted that there are various ways for the power supply housing 117 to flow the cool air to the heat sink 1181, such as: the heat sink 1181 is housed in the power cover 117; alternatively, the power cover 117 is opened and the opening is disposed toward the heat sink 1181; alternatively, an intermediate structure, such as: a duct, a box-like structure, a hood-like structure, etc., and guides the cool air inside the power source cover 117 to the heat sink 1181, etc. through the intermediate structure.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed 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 such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the present application, unless expressly stated or limited otherwise, the first feature may be directly on or directly under the second feature or indirectly via intermediate members. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
