Description

Technical Field

[0001] The utility model relates to cooking equipment, in particular to an air intake structure of cooking equipment. Background Art

[0002] Generally, microwave ovens with air fryers require timely cooling of the air fryer motor during operation, so they are equipped with cooling fan blades and require additional air intakes on the outside of the microwave oven. In microwave ovens with air fryers, the air fryer motor is located at the top of the product's cooking cavity, and because the front of the product is the main exterior surface, the air intakes are generally located on the top, left or right sides, or back of the product. Products with air intakes at the top have limitations on appearance and must reserve a convex air intake. For products with air intakes on the left and right sides and back, air flow may be affected by the external environment, which can affect air intake. This means that when the product is placed close to the user's cabinet or wall, if there is only a small amount of space between the outside of the product and the user's cabinet or wall, the outside air intake will be poor, affecting the air intake volume. Utility Model Content

[0003] The purpose of the present utility model is to provide an air intake structure for a cooking device, wherein the air intake end of the cooking device product is arranged at an upper position on the front surface of a front panel. Compared with other cooking device products, the top appearance of this cooking device product does not need to be compromised, and no convex structure or the like is required, thereby effectively reducing the height of the entire device. Furthermore, the front of this cooking device product is an interface that requires operation, so when a user places the cooking device product, there is definitely enough space reserved for operation. When the amount of external air intake is sufficient, it will not affect the amount of air intake into the cooking device, thereby improving the internal cooling effect of the cooking device.

[0004] The purpose of this utility model is achieved in this way:

[0005] An air intake structure of a cooking device includes an air intake end for connecting external air with a heat dissipation channel inside the cooking device. The cooking device includes a front panel, and the air intake end is arranged on the upper part of the front surface of the front panel.

[0006] The air inlet end is set above the user's operating space. When the user places the cooking equipment, there must be enough space reserved for operation. If the outside air intake is sufficient, it will not affect the air intake into the cooking equipment, and the internal cooling effect of the cooking equipment will be better.

[0007] The cooking device further includes a decorative cover disposed on the front panel, the decorative cover covering and shielding the air inlet of the front panel. The decorative cover covers and shields the air inlet of the front panel, making it difficult for a user to see the air inlet of the front panel during operation or when standing directly in front of the product, and making it difficult for a user to see the internal structure of the product through the air inlet, thereby maintaining the overall appearance of the product.

[0008] The front panel is provided with a decorative cover at the air inlet end, and the decorative cover is provided with ventilation holes connecting the air inlet end with the outside air, so as to prevent the decorative cover from completely blocking the air inlet end and affecting the air intake into the cooking appliance.

[0009] A plurality of ventilation holes are provided on the front end surface of the decorative cover, and a protrusion is provided on the inner side of the decorative cover corresponding to each ventilation hole. An upper air inlet gap is formed between the top of each protrusion and the inner top wall of the corresponding through hole, and a lower air inlet gap is formed between the bottom of each protrusion and the inner top wall of the corresponding through hole; the upper air inlet gap and the lower air inlet gap are respectively connected to the air inlet end of the front panel.

[0010] The outside cold air enters the air inlet end of the front panel through the upper air inlet gap and the lower air inlet gap respectively. On the one hand, the outside air is diverted and enters the air inlet end of the front panel. On the other hand, the protrusion effectively blocks the air inlet end of the front panel without affecting the air intake of the front panel. It is not easy for the user to observe the air inlet end of the front panel when operating or standing directly in front of the product, and it is not easy to see the internal structure of the product through the air inlet end, thereby ensuring the overall appearance of the product.

[0011] The protrusion is protrudingly arranged on the inner side of the decorative cover and forms a reinforcing rib portion for increasing the mechanical strength of the decorative cover, and a ventilation distance is left between the protrusion and the front surface of the front panel.

[0012] The ventilation holes and / or protrusions are provided with an air guiding slope for guiding outside air into the air inlet end of the front panel, and the air guiding slope effectively reduces wind resistance.

[0013] The decorative cover is provided with a positioning portion for positioning and mounting on the front panel, and the decorative cover is provided with a fixing portion for fixing on the front panel.

[0014] The front panel is provided with an opening corresponding to the cooking cavity of the cooking device, and the cooking device further includes a door body for opening and closing the opening, and a control box located on one side of the door body, and the air inlet end is located above the opening, the door body and the control box;

[0015] The control box is provided with buttons, knobs or a touch-type control display screen.

[0016] A plurality of air inlet holes arranged at intervals and forming an air inlet end are provided on the front surface of the front panel.

[0017] The cooking device includes a microwave oven, an oven, or a microwave oven with an air fryer function;

[0018] The microwave oven with air fryer function includes a hot air assembly arranged on the top of the cooking cavity. The hot air assembly includes a cooling fan arranged on the heat insulation cover and used to drive external air along the air inlet end into the internal heat dissipation channel of the cooking device. When the cooling fan is running, the external cold air is sucked into the internal heat dissipation channel of the cooking device to dissipate heat from the electrical components in the heat dissipation channel, thereby improving the service life of the product.

[0019] The beneficial effects of the utility model are as follows:

[0020] This cooking equipment product sets the air intake end connected to the outside air at the upper front position in the main viewing direction (the air intake end is set at the upper front surface of the front panel). Compared with other cooking equipment products, the top appearance of this cooking equipment product does not need to be compromised, and no convex structure is required, which effectively reduces the height of the entire machine. In addition, the front of this cooking equipment product is the interface that requires operation. When the user places the cooking equipment product, there will definitely be enough space reserved for operation. Therefore, the air intake is more direct, the fluidity is better, and the cooling effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
