Embodiment 1

[0031] The preferred embodiment discloses a self-cleaning nozzle for a range hood. Such as figure 1 As shown, the spray head 1 includes a liquid inlet portion 12 , a connecting portion 13 and an end cap 11 which are sequentially connected. At the connection between the base and the end cover 11 , the base is concave and the end cover 11 is convex, and a slit nozzle 2 for spraying cleaning agent is formed between the connection part 13 and the end cover 11 . The wide-mouth end 21 of the slit-type spout 2 is located on the outer peripheral surface of the base, and the narrow-mouth end 22 of the slit-type spout 2 is connected to the cleaning agent channel 3 .

[0032] The base is connected to a detergent storage device, and the detergent can be led to the slotted spout 2 through a detergent channel 3 in the base. The dot spray of the existing cleaning nozzle is converted into surface spray to ensure that the cleaning agent can cover the entire oil screen and thoroughly clean th...

Embodiment 2

[0038] The preferred embodiment discloses a self-cleaning nozzle for a range hood. The spray head includes a connected base and an end cover, and a slit nozzle for spraying cleaning agent is formed between the base and the end cover; the base is connected to the cleaning agent storage device, and the cleaning agent can be introduced through the cleaning agent channel in the base to the slit spout.

[0039] The specific structure of the base is not limited, as long as a slit nozzle for spraying cleaning agent can be formed between the end cover and the cleaning agent can be guided to the slit nozzle through the cleaning agent channel in the base.

Embodiment 3

[0041] This preferred embodiment discloses a range hood. Such as Figure 6 and Figure 7 As shown, the range hood includes a housing (not shown in the figure), on which an oil net 5 is arranged; the cross section of the oil net 5 is concave, and the oil net 5 is provided with a concave structure such as preferred embodiment 1 or The spray head 1 described above; the spray head 1 is connected to the cleaning agent storage device through the connecting piece 6 . The slit nozzle 2 of the spray head 1 is adjacent to the oil screen 5, and the cleaning agent can be sprayed on the oil screen 5 through the slit nozzle 2 to realize the self-cleaning of the range hood. In order to obtain a better cleaning effect, the included angle between the spray angle of the slit nozzle 2 and the oil screen 5 to be cleaned is 25° to 35°. Preferably, the included angle between the spray angle and the oil screen 5 to be cleaned is 30°.

Abstract

The invention discloses a self-cleaning spray nozzle for a range hood and the range hood with the self-cleaning spray nozzle, which belong to the field of range hoods and fittings thereof and are designed for solving the problem that existing devices have a poor cleaning effect. The self-cleaning spray nozzle for the range hood comprises a base and an end cover which are connected, wherein a slit-type spray orifice for spraying a cleaning agent is formed between the base and the end cover; the base is connected to a cleaning agent storage device; and the cleaning agent can be led to the slit-type spray orifice by a cleaning agent channel in the base. The self-cleaning spray nozzle for the range hood has the beneficial effects that the range hood cleaning agent can be sprayed out through the slit-type spray orifice, the point-like spray of the cleaning agent is converted into the surface-like spray of the cleaning agent to ensure that the cleaning agent can cover the whole oil screen, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the field of a range hood and its accessories, in particular to a self-cleaning nozzle for a range hood and a range hood provided with the nozzle. Background technique [0002] Range hood is a common household appliance used to remove kitchen fumes. Long-term smoking of oil fume will cause some oil stains to remain on the oil net, and the effect of oil fume absorption will become poor. The range hood with self-cleaning function can generate high-temperature steam or spray decontamination gas liquid to clean the oil screen. [0003] Most of the existing nozzles of range hoods with self-cleaning function are devices including one or more point-shaped (hole-shaped) nozzles. Even if multiple nozzles are installed, it is impossible to ensure the comprehensive cleaning of the oil screen; and the sealing is poor, and it is easy to leak water, Leakage. Contents of the invention [0004] One object of the present invention is to pr...
