Example one

Referring to fig. 1 to 3, embodiments of the present application provide a heat dissipation assembly for a cooking apparatus that cooks with steam to cool an outer discharge steam and then discharge the cooled outer discharge steam out of the cooking apparatus.

The heat dissipation assembly provided by the present embodiment includes a heat dissipation air duct 2 and a fan 23. The heat dissipation air duct 2 is provided with an air outlet 3 and a steam inlet 24, the discharged steam of the cooking device enters the heat dissipation air duct 2 through the steam inlet 24, the fan 23 is air-out towards the air outlet 3, the steam inlet 24 is positioned between the air outlet 3 and the fan 23, that is, the position where the steam enters the heat dissipation air duct 2 is positioned between the air outlet 3 and the fan 23, so that the air supply range of the fan 23 covers all the steam entering the heat dissipation air duct 2.

The cool air blown by the fan 23 has the functions of cooling the steam and driving the steam to flow to the air outlet 3, so that the steam is condensed in the heat dissipation air duct 2 to form condensed water, and in order to collect the condensed water, a concave water collection portion 22 is formed on the bottom wall of the heat dissipation air duct 2, the concave water collection portion 22 is sunken relative to the bottom wall of the heat dissipation air duct 2, so that the condensed water falls into, flows into and is collected in the concave water collection portion 22 under the action of gravity.

The drainage hole 222 is formed in the concave water collecting part 22, the drainage hole 222 is communicated with the outside of the heat dissipation air duct 2, one end of the drainage tube 4 is communicated with the drainage hole 222, and the other end of the drainage tube 4 extends out of the heat dissipation air duct 2, so that accumulated water in the concave water collecting part 22 is timely drained out of the heat dissipation air duct 2 through the drainage tube 4, and the influence of the accumulated water on the operation safety of the cooking device is effectively reduced.

Optionally, the discharge hole 222 is connected with the drainage tube 4 through an interface with a flow control function, so as to avoid the situation that the connection between the discharge hole 222 and the drainage tube 4 fails due to excessive water accumulation.

Optionally, the junction between the discharge hole 222 and the drain tube 4 may be sealed to reduce the risk of water seepage or water leakage therethrough.

In this embodiment, the inner wall of recessed sump portion 22 includes a guide slope 220, and guide slope 220 is inclined downward from the edge of recessed sump portion 22 toward discharge hole 222, thereby enabling accumulated water to flow and collect along guide slope 220 toward discharge hole 222 more efficiently.

Optionally, the number of the guide inclined planes 220 may be multiple, the plurality of guide inclined planes 220 are sequentially arranged from top to bottom, a buffer plane 221 is connected between adjacent guide inclined planes 220, when the condensed water is generated more in a unit time, the condensed water flows to the discharge hole 222 at a larger flow rate, which easily causes untimely drainage at the discharge hole 222 and splashing of the condensed water, and by providing the buffer plane 221, the flow speed of the condensed water on the guide inclined planes 220 can be reduced to a certain extent, and splashing of the condensed water can be reduced.

In this embodiment, at least a portion of the concave water collecting portion 22 is located between the steam inlet 24 and the air outlet 3, that is, a portion or all of the concave water collecting portion 22 is located between the steam inlet 24 and the air outlet 3, so that the concave water collecting portion 22 is disposed corresponding to a flow path of steam, and most of the steam is directly condensed in the concave water collecting portion 22 during the flowing process.

Further, if a situation occurs in which the steam condensation position is located outside the recessed water collection part 22, the condensed water can flow into the recessed water collection part 22 by the blowing of the fan 23.

Alternatively, since the amount of water accumulated in the recessed water collection part 22 is greater than that of other positions of the heat dissipation duct 2, rust prevention and leakage prevention reinforcement treatment may be performed on the recessed water collection part 22. For example, a rust and leak proof coating is applied.

In this embodiment, the distance between the concave water collecting portion 22 and the steam inlet 24 is greater than the distance between the concave water collecting portion 22 and the air outlet 3, that is, the concave water collecting portion 22 is disposed near the air outlet 3, so as to increase the condensation stroke of the steam, improve the collection amount of the condensed water, and avoid causing the steam to directly discharge outwards through the air outlet 3 to wet the front area of the air outlet 3.

In the alternative of this embodiment, heat radiation assembly still includes the water receiving container 5 that is linked together with the other end of drainage tube 4, and water receiving container 5 is located the below of discharge hole 222 to make ponding can converge in water receiving container 5 along drainage tube 4 under the effect of gravity, reach the effect that ponding limit gathering was discharged, furthest shortens the dwell time of comdenstion water in sunken water-collecting part 22, further reduces the risk that the comdenstion water caused the influence to cooking device operation security.

In this embodiment, the water receiving container 5 is in the shape of a groove, which is not only convenient for observing the water amount, but also convenient for cleaning accumulated water and the inner wall of the groove-shaped water receiving container 5.

In an alternative of this embodiment, the other end of the drainage tube 4 is provided with a switch valve, so that the accumulated water in the recessed water collecting part 22 can be periodically discharged by opening and closing the switch valve, and the discharged accumulated water can be received by other containers in the kitchen.

In an alternative of this embodiment, a distance between the steam inlet 24 and the air outlet 3 along the extending direction of the heat dissipation air duct 2 is defined as a first distance, a distance between the steam inlet 24 and the fan 23 along the extending direction of the heat dissipation air duct 2 is defined as a second distance, and a ratio of the first distance to the second distance is not less than 1.

That is, the steam inlet 24 is disposed closer to the fan 23, so that the flow path of the steam in the heat dissipation air duct 2 can be longer, the condensation amount of the steam in the heat dissipation air duct 2 can be increased, the temperature and the total amount of the steam discharged from the air outlet 3 of the heat dissipation air duct 2 can be reduced, and the fumigation and other influences of the steam on the indoor space and the user can be reduced.

In contrast, in the case of the heat dissipation duct 2 without the recessed water collection portion 22 and the discharge hole 222, in order to reduce the influence of the accumulated water on the cooking device, it is necessary to minimize the generation of condensed water, and therefore, the steam inlet 24 needs to be disposed as close as possible to the air outlet 3, which results in an increase in the amount of discharged steam, and the temperature of the discharged steam is too high, which aggravates the fumigation and other influences on the indoor furnishings and users, and even easily burns the users.

In this embodiment, the ratio of the distance between the first distance and the second distance is not less than 3, and the flow path of the discharged steam is further extended, so that the steam can be condensed and cooled to the maximum extent. For example, the ratio between the first distance and the second distance is 3, 4 or 5.
