[0001] The invention belongs to the technical field of range hoods, and in particular relates to a cleaning nozzle structure and a range hood using the same. Background Art

[0002] The range hood can be said to be one of the essential household appliances in modern family kitchens. The performance and ease of use of the range hood largely determine the quality of the air in the home and the health of housewives, so it must not be ignored. After long-term use of the range hood, the surface and inner cavity will be filled with oil and dirt, affecting its normal exhaust effect, so regular and correct cleaning of the range hood is a prerequisite for ensuring the normal operation of the range hood.

[0003] Most people are used to disassembling the range hood for cleaning, which is time-consuming and easy to damage the parts. Therefore, the automatic cleaning range hood came into being.

[0004] The traditional automatic cleaning structure is only designed with an impeller blade cleaning nozzle, which can automatically clean the impeller blades. Considering the water leakage prevention limitations of the cleaning process, a simple slit structure is generally adopted, which can only clean part of the blade area. There are few cleaning nozzles that can cover the upper and lower edges of the blades and the middle disk of the impeller. The cleaning effect on the impeller disk and the overall blades is not good, and the cleaning area is limited. Summary of the invention

[0005] The purpose of the present invention is to provide a cleaning nozzle structure and a range hood using the same, so as to solve the problem in the technical field of existing range hoods that the cleaning area of ​​the nozzle with a slit structure is limited and the cleaning effect is poor.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A cleaning nozzle structure comprises an impeller blade cleaning nozzle and an impeller disc cleaning nozzle arranged on a water inlet pipe, wherein the impeller blade cleaning nozzle is provided with a first water injection hole, the impeller disc cleaning nozzle is provided with a second water injection hole, and the central axis of the impeller blade cleaning nozzle is arranged at an angle to the central axis of the impeller disc cleaning nozzle.

[0008] A further technical solution of the present invention is:

[0009] The impeller blade cleaning nozzle is in a conical shape.

[0010] The cone opening of the impeller blade cleaning nozzle is between 35° and 50°.

[0011] The impeller blade cleaning nozzle is provided with at least two rows of first water jet holes from top to bottom; the first water jet holes in each row are evenly arranged around the conical impeller blade cleaning nozzle.

[0012] The cone top of the impeller blade cleaning nozzle faces the impeller blade of the range hood, the first water jet holes are arranged in four rows, and the opening diameter of the first water jet holes is 0.8mm-1.2mm.

[0013] The impeller mid-disk cleaning nozzle is in a frustum shape.

[0014] The impeller center disk cleaning nozzle is used for spraying a bottom circular plane toward the impeller center disk of the range hood.

[0015] The second water jet holes are arranged at the center of the bottom circular plane and are provided in at least two rows. The third water jet holes are arranged at the edge of the jet surface of the impeller mid-disk cleaning nozzle.

[0016] The central axis of the impeller blade cleaning nozzle is arranged perpendicularly to the central axis of the impeller mid-disk cleaning nozzle.

[0017] The present invention further provides a range hood, comprising the above-mentioned cleaning nozzle structure and a mounting member, wherein one end of the mounting member is sleeved on the water inlet pipe, and the other end is fixed on the housing of the range hood.

[0018] Compared with the prior art, the technical effect of the present invention is mainly reflected in: the cleaning nozzle structure has two cleaning nozzles, one nozzle for cleaning the impeller blades, and the other nozzle for cleaning the impeller center plate, which expands the cleaning area of ​​the range hood and significantly improves the cleaning effect of the range hood.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] Example 1

[0026] Embodiment 1 of the present invention provides a cleaning nozzle structure, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an impeller blade cleaning nozzle 1 and an impeller disk cleaning nozzle 2 arranged on a water inlet pipe 4, the impeller blade cleaning nozzle 1 is provided with a first water injection hole 11, the impeller disk cleaning nozzle 2 is provided with a second water injection hole 21, and the central axis of the impeller blade cleaning nozzle 1 is arranged at an angle to the central axis of the impeller disk cleaning nozzle 2. The cleaning nozzle structure in the present invention includes two cleaning nozzles: an impeller blade cleaning nozzle 1 and an impeller disk cleaning nozzle 2, and these two cleaning nozzles can clean the impeller blades 5 and the impeller disk 6 at the same time, thereby expanding the cleaning area and significantly improving the cleaning effect.

[0027] Furthermore, the impeller blade cleaning nozzle 1 is in a conical shape, and in the present embodiment, the cone top of the conical nozzle faces the impeller blade 5 of the range hood. The conical cleaning nozzle can cover a wider cleaning area and improve the cleaning effect.

[0028] Preferably, the cone opening of the impeller blade cleaning nozzle 1 is between 35° and 50°, which can cover a wider cleaning area.

[0029] On the impeller blade cleaning nozzle 1, at least two rows of first water injection holes 11 are provided from top to bottom. In the present embodiment, four rows of first water injection holes 11 are provided to ensure that all areas of the impeller blades 5 are covered and the cleaning is more thorough; the first water injection holes 11 are evenly arranged around the conical impeller blade cleaning nozzle 1; the opening diameter of the first water injection holes 11 is 0.8 mm to 1.2 mm. The purpose of providing such a size of aperture is to ensure a high water and gas outlet speed and a better cleaning effect.

[0030] Furthermore, the impeller center disk cleaning nozzle 2 is in the shape of a truncated cone, and the injection bottom circular plane 22 of the truncated cone faces the impeller center disk 6 of the range hood.

[0031] The second water injection holes 21 are arranged in at least two rows, and in this embodiment, three rows are arranged evenly at the center of the bottom circular plane 22 of the impeller mid-disk cleaning nozzle 2, which can cover the main area of ​​the impeller mid-disk 6 and focus on cleaning this area.

[0032] A third water injection hole 23 is also provided on the impeller disc cleaning nozzle 2. The third water injection hole 23 is located at the edge of the injection surface of the impeller disc cleaning nozzle 2. It can clean the edge area of ​​the impeller disc 6 to improve the cleaning efficiency.

[0033] In order to adapt to the position structure of the impeller and the impeller disc of the existing range hood and improve the cleaning effect, the central axis of the impeller blade cleaning nozzle 1 and the central axis of the impeller disc cleaning nozzle 2 are vertically arranged.
