Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a top-vented head cover assembly and cooking appliance. Background Technology

[0002] In the existing technology, some cooking appliances have the opening set on the top. However, with this setting, the heating device is directly discharged through the air outlet without guidance, which causes heat flow to accumulate inside the cover at the position corresponding to the air outlet, generating eddies and affecting the air output effect. Utility Model Content

[0003] The purpose of this invention is to provide a top-vented cover assembly and cooking utensils. Through the air guide mechanism extending to the bottom of the liner, the heat generated by the heating component can be guided out, avoiding hot air vortices, etc.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] On one hand, the top-vented head cover assembly includes an upper cover and an inner liner located below the upper cover and forming an assembly cavity with the upper cover. A first cooling fan and a heating component are sequentially arranged below the inner liner. The inner liner extends partially to form a heat dissipation channel communicating with the air outlet at the upper cover. An air guide mechanism extending to the lower part of the inner liner is provided in the heat dissipation channel. The air guide mechanism divides the entrance of the heat dissipation channel into a horizontal heating trajectory trend and an upward air outlet trajectory trend.

[0006] Furthermore, the air guide mechanism located in the liner extends upwards on the side, forming a division of the space below the liner, and after the division, the airflow in part of the space is guided into the baffle in the heat dissipation channel.

[0007] Furthermore, the baffle extends upward and bends to form an overlap portion that overlaps with the inner lining.

[0008] Furthermore, it also includes a heat dissipation hood covering the inner lining, wherein the heat dissipation hood has a heat dissipation opening at its center facing the inner wall of the upper cover.

[0009] Furthermore, the side of the heat sink is connected to the heat dissipation channel, and the heat sink and the heat dissipation channel form an integral structure.

[0010] Furthermore, a second cooling fan is provided inside the heat sink, and a drive mechanism is provided above the heat sink. The air guide mechanism is connected to the bracket of the drive mechanism near the inner lining.

[0011] Furthermore, an arc-shaped transition surface is formed between the top of the heat dissipation shroud and the heat dissipation channel, and the arc-shaped transition surface forms a guiding trajectory toward the air outlet.

[0012] Furthermore, the heat dissipation channel and air outlet are positioned off-center from the head cover.

[0013] On the other hand, the cooking appliance includes a top-vented cap assembly as described above, and a pot body that matches the cap assembly, the pot body having a handle on its side.

[0014] Furthermore, the handle is located on one side of the cooking appliance, while the heat dissipation channel and air outlet are located near the other side of the cooking appliance.

[0015] The beneficial effects of this utility model are as follows: In this invention, by adding a wind guide mechanism and extending it below the liner, the heat generated by the heating component can be guided into the heat dissipation channel and air outlet, avoiding heat accumulation and the generation of eddies, and improving the flow efficiency of airflow.

[0016] In this invention, due to the setting of baffles, etc., the heat flow after diversion is blocked, and then flows upward into the heat dissipation channel along the air guide mechanism, thereby ensuring heat dissipation. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0019] See attached document Figure 1-8 As shown, the top-vented head cover assembly in this embodiment includes an upper cover 100 and an inner liner 200 located below the upper cover 100 and forming an assembly cavity with the upper cover 100. Other structures can be assembled into the assembly cavity. A first cooling fan 210 and a heating component 220 are sequentially arranged below the inner liner 200. In this embodiment, the upper cover 100 can be a panel or similar structure. A heat dissipation channel 300 is provided on the inner liner 200. Specifically, the inner liner 200 partially extends to form an air outlet 110 communicating with the upper cover 100. The heat dissipation channel 300 has an opening at the inner lining 200, allowing it to connect with the heating cavity formed by the heating component 220. An air guide mechanism 400 is then installed within the heat dissipation channel. Unlike direct installations, in this embodiment, the air guide mechanism 400 extends below the inner lining 200 after passing through the heat dissipation channel 300. This air guide mechanism 400 divides the airflow at the entrance of the heat dissipation channel and within the heating cavity below the inner lining, creating a horizontal heating trajectory and an upward air outlet trajectory. This division reduces airflow accumulation, especially when the air outlet and heat dissipation channel are located on the side, preventing accumulation due to obstruction by the inner wall. Furthermore, it promptly directs airflow to the heat dissipation channel, facilitating the fulfillment of airflow requirements during cooking.

[0020] In this embodiment, in order to improve the guiding efficiency and ensure that hot air does not mix below the liner 200 and can enter the heat dissipation channel 300, the side of the air guiding mechanism 400 located at the liner 200 extends upward to form a division of the space below the liner 200. After the division, the airflow in part of the space is guided into the baffle 500 in the heat dissipation channel 300. At this time, the baffle 500 can not only divide the heating chamber, but also guide the hot air into the heat dissipation channel 300, thereby achieving the effect of guiding the air into the air outlet 110.

[0021] In this embodiment, in order to fix and stabilize the guide mechanism 400, the baffle 500 can be extended and bent upward to form an overlap portion 510 that overlaps with the inner lining 200. In this embodiment, the overlap portion 510 and the baffle 500 can form an L-shaped structure, with one part perpendicular to the inner lining and the other part parallel to the inner lining. Specifically, the baffle can also be set as a triangle, and the three sides of the triangle can form a dividing hypotenuse, an overlap side, and a connecting side connecting the heating cavity and the inner lining, respectively.

[0022] To prevent excessive heat from directly contacting the top cover 100 and affecting it, a heat dissipation shroud 600 is also included, which is placed on the inner liner 200. The heat dissipation shroud 600 has a heat dissipation opening 610 at its center facing the inner wall of the top cover. In this embodiment, the heat dissipation opening 610 also prevents the accumulation of airflow inside the heat dissipation shroud 600.

[0023] In this embodiment, the heat dissipation area formed by the heat dissipation vent 610 is larger than the heat dissipation area formed by the cross-section of the heat dissipation channel 300. In actual use, the heat dissipation channel only partially discharges some of the hot air to avoid excessive accumulation that would affect the taste of the food. Therefore, at this time, the heat dissipation channel 300 and the vent 110 only discharge a portion of the hot air.

[0024] To facilitate production, the side of the heat sink 600 is connected to the heat dissipation channel 300. At this point, some hot air will also flow into the heat dissipation channel 300 from below the heat sink 600. Then, during manufacturing, the heat sink 600 and the heat dissipation channel 300 can be produced as a single unit, forming an integrated structure. This method saves costs and speeds up assembly.

[0025] To achieve heat dissipation, a second cooling fan 620 is provided inside the heat sink 600, and a drive mechanism 630 is provided above the heat sink 600. The air guide mechanism 400 is connected to the bracket of the drive mechanism 630 near the inner liner 200. At this time, the air guide mechanism 400 is fixedly assembled through the bracket connection.

[0026] Referring to the accompanying drawings, an arc-shaped transition surface 310 is formed between the top of the heat dissipation shroud 600 and the heat dissipation channel 300, and the arc-shaped transition surface 310 forms a guiding trajectory towards the air outlet. In this way, hot air is guided upwards from the bottom and then into the shroud.

[0027] Preferably, in this embodiment, the heat dissipation channel 300 and the air outlet 110 are positioned off-center from the head cover. In this embodiment, they are positioned closer to the side, especially closer to the rear, so that the air is thrown out to the side. Therefore, compared to the center position, the off-center side is a more suitable location for air outlet.

[0028] In this embodiment, the air guiding mechanism is actually an air guiding plate. The air guiding plate is then integrally bent to form an overlapping part 510 and a baffle 500. The air guiding plate then protrudes along its length to form reinforcing ribs 410. The number and length of the reinforcing ribs 410 can be adjusted according to requirements. In this embodiment, a first cooling fan 210 and a second cooling fan 620 are respectively provided above and below the liner 200. The first cooling fan 210 is positioned above the heating component 220 to accelerate the heat flow of the heating component. At this time, a drive mechanism 630 formed by a motor can be provided at the heat sink 600. The projection of the drive mechanism 630 is located at the heat dissipation port 610, which can also assist in heat dissipation.

[0029] In this embodiment, the entire air guide plate forms an arc-shaped air guide trajectory within the heat dissipation channel 300, allowing hot air to slowly enter along this trajectory with a certain transition space. If a straight plate is used, although the guiding effect is strong, the airflow is prone to generating impact force, resulting in a poor experience.

[0030] See attached document Figure 4 As shown in this embodiment, the entire air guide plate, from the inner lining to the top cover, exhibits a trend of first widening and then narrowing in width. This trend creates a flow pattern where the airflow first diffuses to avoid accumulation, and then narrows and exits through a small air outlet.

[0031] See attached document Figure 5-8 As shown, this embodiment also discloses a cooking appliance, including a top-vented cover assembly and a pot body 700 that matches the top-vented cover assembly. The pot body 700 has a handle 710 on its side. This allows for direct handling from the side, rather than the top, thus avoiding the top vent 110 and ensuring safety.

[0032] To enhance safety, the handle 710 is positioned on one side of the cooking appliance, while the heat dissipation channel 300 and air outlet 110 are located near the other side of the cooking appliance. This separation of the two sides improves safety.

[0033] In the prior art, when the top air outlet causes heat to accumulate in the lining, a partition needs to be installed on the back of the cooking appliance to create a gap between it and the wall, so as to prevent the accumulated heat from affecting the wall. However, in this embodiment, due to the addition of the guiding mechanism, the heat under the lining can be discharged in time, reducing the generation of eddies, etc., so there is no need to install a partition, and the whole structure is simpler.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
