Description

Technical Field

[0001] The invention belongs to the field of clothing processing equipment, and in particular, relates to a spray head for a washing device and the washing device. Background Art

[0002] Ultraviolet rays are generated by the outer electrons of atoms being excited. They refer to light with a wavelength of 10 to 400 nanometers. They can be divided into UVA (wavelength 320 to 400 nanometers, long wave), UVB (wavelength 290 to 320 nanometers, medium wave), and UVC (wavelength 100 to 290 nanometers, short wave). Ultraviolet rays in the range of 254 to 257 nm have the best sterilization effect. After absorbing ultraviolet rays, the DNA, nucleic acid and nucleoprotein of bacteria cause DNA chain breakage, resulting in the cross-linking of nucleic acid and protein rupture, killing the biological activity of nucleic acid and causing the death of bacteria.

[0003] At present, UV lamps are developing rapidly. Compared with quartz UV lamps, UV lamps have many advantages. The spectrum they produce is relatively fixed and the efficiency is high. The light intensity output per unit area is high and the response is stable. The volume is small and easy to integrate; the service life is long and the price is low compared with quartz UV lamps.

[0004] There are also some problems with the use of UV lamps in sterilization. As the distance of UV lamp action increases, the intensity of UV light decreases significantly, and the sterilization effect is greatly reduced. In addition, when UV sterilization is performed during the fabric washing process, the UV sterilization effect will be further attenuated by the influence of water mist and droplets in the washing barrel. Moreover, the light of UV LED lamps is relatively scattered, making it difficult to focus on specific parts of clothing for sterilization.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a spray head for sterilizing clothes while spraying them and a washing device having the spray head.

[0012] Further optionally, the first curved surface is parallel to the second curved surface.

[0013] Further optionally, the ultraviolet lamp is located on the second curved surface, and the critical incident angle at which the ultraviolet rays emitted by the ultraviolet lamp are totally reflected when they are emitted from water into the air is θ0.

[0038] Example 1

[0039] This embodiment provides a spray head for washing equipment, such as Figure 1-6As shown, the shower head includes a shower head body and an ultraviolet lamp 5. The shower head body includes a shower head shell 2. A shower head cavity 6 is formed inside the shower head shell 2. The shower head cavity 6 is connected to the water inlet pipe 1 of the washing device. The shower head shell 2 is also provided with a plurality of spray holes 4. The water in the water inlet pipe 1 enters the shower head cavity 6 and is sprayed out through the spray holes 4 to spray the clothes 8 in the washing device. The ultraviolet lamp 5 is arranged in the shower head cavity 6. During the spraying process, the water in the shower head cavity 6 flows out through the spray holes 4 to form a water flow. The ultraviolet light emitted by the ultraviolet lamp 5 is injected into the water flow through the spray holes 4 and propagates to the surface of the clothes 8 with the water flow to sterilize the clothes 8. The ultraviolet lamp 5 in this embodiment is an ultraviolet LED lamp. In this embodiment, by arranging an ultraviolet LED lamp in the shower head cavity, ultraviolet rays can be propagated to the surface of the clothes 8 along the ejected water flow, and the clothes 8 are sterilized while being sprayed.

[0040] Specifically, Figure 1-6 As shown, the shower head housing 2 includes a shower head front housing 201 and a shower head rear housing 202, the shower head cavity 6 is composed of the shower head front housing 201 and the shower head rear housing 202, a plurality of spray holes 4 are formed on the shower head front housing 201, and the ultraviolet lamp 5 is arranged on the inner wall of the shower head rear housing 202. The plurality of spray holes form a spray surface 3 on the shower head front housing 201, the spray surface 3 is recessed toward the inside of the shower head cavity 6 to form a first arc surface, the shower head rear housing 202 is protruded toward the outside of the shower head cavity 6 to form a second arc surface, and the centers of the first arc surface and the second arc surface are located on the same side of the shower head front housing 201. Preferably, the first arc surface is parallel to the second arc surface. In this embodiment, the spray surface 3 of the spray head is set to be concave inwards and the rear shell 202 of the spray head is convex outwards, so that a double C-shaped mirror structure is formed between the spray surface 3 and the rear shell of the spray head. This is more conducive to the gathering of the spray surface 3 where the ultraviolet rays are concentratedly distributed toward the spray holes 4 after reflection, thereby increasing the efficiency of ultraviolet utilization.

[0041] like Figure 5 As shown in the ultraviolet light path diagram, after the ultraviolet rays are irradiated on the inner wall of the spray surface 3 and the inner wall of the front shell 201 of the shower head, if there is a spray hole 4 at the irradiated part, as shown in the light path a, the light is emitted along the water flow; if there is no spray hole 4 at the irradiated part, as shown in the light path b, the light is reflected back and irradiates the inner wall of the rear shell 202 of the shower head, and is reflected again. The reflected light is irradiated on the inner wall of the spray surface 3 and the inner wall of the front shell 201 of the shower head again, part of which is emitted along the water flow through the spray hole 4, and part of which is reflected back and reflected by the inner wall of the rear shell 202 of the shower head again, and in this cycle, most of the ultraviolet rays can be emitted along the water flow through the spray hole 4, acting on the surface of the clothes 8, and sterilizing the clothes 8.

[0042] Further optionally, the ultraviolet lamp 5 is located on the second curved surface, and the critical incident angle at which the ultraviolet light emitted by the ultraviolet lamp 5 is totally reflected when it is injected into the air from water is θ0. The angle between the ultraviolet light emitted by the ultraviolet lamp 5 and the tangent line of the first curved surface at the spray hole when irradiating the farthest spray hole on the first curved surface 3 is set to θ. In this embodiment, the setting position of the ultraviolet lamp 5 needs to satisfy θ≥θ0. Figure 6 In the optical path diagram of ultraviolet light shown in the figure, optical path C is the optical path irradiated to the farthest spray hole, and the angle between optical path C and the tangent line at the farthest spray hole is θ≥θ0. For example, when the critical incident angle for ultraviolet light to be totally reflected from water into air is 45°, θ≥45° must be satisfied. In this way, when sterilizing clothes 8, water flows into the spray head cavity 6 from the water inlet pipe 1, and then sprays water from the spray hole 4. The ultraviolet LED lamp is powered on, emitting ultraviolet light, which enters the water flow through the spray hole 4, and is totally reflected on the inner surface of the water flow, and propagates to the surface of the clothes 8 with the water flow without attenuation, so that the sprayed water flow 7 becomes a purple light column, and forms a purple light spot on the surface of the clothes 8. While washing, the clothes 8 can be sterilized, and have a good visualization effect.

[0043] Further optionally, in order to have a stronger reflection effect on ultraviolet light and allow more light to be transmitted to the surface of clothing 8 through water flow after reflection, the inner wall of the spray head cavity 6 is preferably made of mirror material, or the inner wall of the spray head cavity 6 is coated with a mirror material coating.

[0044] The ultraviolet lamp 5 of this embodiment includes an ultraviolet lamp packaging structure 501, ultraviolet lamp beads 502, ultraviolet lamp bead connecting wires 503 and ultraviolet lamp power cord 504. The ultraviolet lamp beads 502 are packaged inside the ultraviolet lamp packaging structure 501, and the ultraviolet lamp bead connecting wires 503 connect the ultraviolet lamp beads 502 to the ultraviolet lamp power cord 504. The ultraviolet lamp power cord 504 is connected to an external power supply via the rear shell 202 of the spray head and the water inlet pipeline 1. Preferably, a closed pipeline for routing the ultraviolet lamp power cord 504 is provided on the rear shell 202 of the spray head and the water inlet pipeline 1.

[0045] Example 2

[0046] The difference between this embodiment and embodiment 1 is that one or more conduits are provided on the spray head, one end of the conduit is connected to the spray hole, and the other end extends to the vicinity of the surface of the clothes in the washing device to perform close-range spraying and sterilization on the clothes. One possible implementation is that a conduit is provided on the spray head, one end of the conduit is connected to the entire spray surface, and the other end extends to the vicinity of the surface of the clothes. Another possible implementation is that a plurality of conduits are provided on the spray head, each conduit corresponds to a spray hole one-to-one, or one conduit corresponds to a plurality of spray holes. In order to enhance the reflection effect of ultraviolet light on the inner wall of the conduit, it is preferred that the inner wall of the conduit is made of a mirror material, or the inner wall of the conduit is coated with a mirror material coating.
