Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a protective cover for an air conditioner negative ion generator and an air conditioner. Background Technology

[0002] Negative air ions are primarily composed of negative oxygen ions, but also include other negatively charged ions formed when gas molecules gain excess electrons. Because of their negative charge, negative air ions cause normally positively charged indoor dust, smoke, viruses, and bacteria to gather together, losing their ability to float freely in the air and quickly settling down, thus purifying the air. The high-voltage carbon brushes of negative ion generators discharge at high voltage, ionizing the air and producing negative ions. Air conditioners often have negative ion generators installed to purify the air; the high-voltage carbon brushes of these generators are usually located at the air conditioner's air outlet, and the air conditioner's fan blows the negative ions into the room.

[0003] Because high-voltage carbon brushes carry high voltage, touching them could cause skin burns or electric shocks. Therefore, a protective cover is installed on the outside of the high-voltage carbon brush. In existing technology, the protective cover for negative ion generators is mostly made of ordinary ABS plastic. These materials have high surface resistance and easily accumulate electrostatic fields. This accumulation of electrostatic fields not only causes negative ions to be bound during diffusion, making it difficult for them to distribute evenly in the air and thus reducing air purification efficiency, but it can also attract dust, generate sparks, and pose safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective cover for an air conditioner negative ion generator and an air conditioner, which solves the problems of static electricity accumulation in the protective cover of the negative ion generator leading to reduced negative ion diffusion effect and safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective cover for an air conditioner negative ion generator includes: a protective cover body, the interior of which is hollow, an opening at the bottom of which is provided, a plurality of holes on which are provided, and a plurality of recesses and / or protrusions on which are provided on the surface of which are provided.

[0007] Preferably, the bottom of the protective cover body is provided with an opening, and the opening of the protective cover body is provided with a fixing structure for connecting with the air conditioner casing.

[0008] Preferably, the fixing structure is a connecting ear plate, which is fixed to the edge of the opening and is arranged vertically downward.

[0009] Preferably, two connecting ear plates are provided, and the two connecting ear plates are respectively provided on the two sides corresponding to the opening.

[0010] Preferably, a limiting cross plate is provided on one end of one of the connecting ear plates that is connected to the protective cover body and on the side away from the other connecting ear plate.

[0011] Preferably, the protective cover body and the connecting ear plate are integrally formed.

[0012] Preferably, the limiting cross plate and the connecting ear plate are integrally formed.

[0013] Preferably, the protective cover body includes four side protective plates and a top protective plate that is connected to the four side protective plates simultaneously, and the left and right side protective plates are configured as arc-shaped.

[0014] Preferably, one of the arc-shaped side protective plates is provided with an opening for cleaning the high-voltage carbon brush of the negative ion generator.

[0015] This utility model has the following beneficial effects:

[0016] This invention features several recesses and / or protrusions on the surface of the protective cover, increasing the surface area and making the charge distribution on the protective cover surface uneven. This disrupts the accumulation of electrostatic field, reduces the adsorption of dust on the protective cover surface, helps keep the negative ion generator clean, and avoids safety hazards such as sparks.

[0017] In the injection molding process of the protective cover body, antistatic material is uniformly added, which can effectively reduce the surface resistance of the protective cover and reduce the binding of negative ions by the electrostatic field during diffusion.

[0018] An air conditioner is also provided, including a protective cover for the air conditioner negative ion generator as described in any of the above.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1 to 5 As shown, a protective cover for an air conditioner negative ion generator includes: a protective cover body 1, the interior of which is hollow, and several holes are provided on the body. The surface of the protective cover body 1 has several recesses and / or protrusions. The hollow interior of the protective cover body 1 provides space for the high-voltage carbon brush 4 of the negative ion generator, which is located inside the protective cover body 1 after installation. The uneven surface of the protective cover body 1 increases the surface area, making the charge distribution on the surface of the protective cover body 1 uneven, disrupting the accumulation of electrostatic field, reducing dust adsorption on the protective cover surface, helping to keep the negative ion generator clean, and avoiding safety hazards such as sparks. When manufacturing the protective cover body 1, corresponding uneven structures can be designed on the surface of the injection mold cavity, or ABS material with moderate shrinkage can be selected, which helps to form a stable uneven structure during injection molding. Additionally, antistatic materials, such as 3%–5% nano-level conductive carbon powder, can be uniformly added during injection molding, controlling the surface resistance of the protective cover to within 10 ohms. 6 ~10 9 The Ω effectively reduces the surface resistance of the protective cover, breaking the electrostatic field's binding effect on negative ions. This allows negative ions to diffuse more freely into the air, thereby increasing the concentration of negative ions and improving air purification efficiency.

[0028] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the bottom of the protective cover body 1 has an opening, and a fixing structure for connecting to the air conditioner housing is provided at the opening of the protective cover body 1. During installation, the fixing structure is connected to the air conditioner housing, and the high-pressure carbon brush 4 is located inside the protective cover body 1 through the opening. The fixing structure is a connecting lug 2, which is fixed to the edge of the opening and is vertically downward. The air conditioner housing has a space for the connecting lug 2 to extend into. The connection method can be adhesive or other existing methods, so that when the connecting lug 2 is connected to the air conditioner housing, the opening of the protective cover body 1 contacts the air conditioner housing, thereby allowing the high-pressure carbon brush 4 to be located within the space formed by the protective cover body 1 and the air conditioner housing.

[0029] Furthermore, to improve the reliability of the connection, two connecting lugs 2 are provided for connection, and the two connecting lugs 2 are respectively located on the two sides of the opening to improve stability.

[0030] Furthermore, a limiting plate 3 is provided on one end of one of the connecting ear plates 2 that is connected to the protective cover body 1 and on the side away from the other connecting ear plate 2. The air conditioner housing is also provided with a groove that cooperates with the limiting plate 3, so as to play a limiting role when installing the protective cover body 1, and facilitate quick installation.

[0031] Furthermore, the protective cover body 1 and the connecting ear plate 2 are integrally formed, and the limiting cross plate 3 and the connecting ear plate 2 are integrally formed.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the protective cover body 1 includes four side protective plates and a top protective plate 11 connected to the four side protective plates simultaneously. The left and right side protective plates are designed in an arc shape. Since the protective cover body 1 is located at the air conditioner outlet, which is also equipped with air guide vanes, the arc-shaped side protective plates ensure that the protective cover body 1 as a whole does not obstruct the rotation of the air guide vanes.

[0033] Furthermore, such as Figure 4 As shown, one of the arc-shaped side protective plates has an opening, and the air conditioner negative ion generator protective cover is set near the air conditioner air guide blades, so that when the air conditioner air guide blades rotate, the tail of the air guide blades can extend into the negative ion generator protective cover to clean the dust from the high-pressure carbon brush 4 and increase the amount of negative ions generated.

[0034] An air conditioner is also disclosed, including any of the air conditioner negative ion generator protective covers described in the claims, which incorporate all the beneficial effects of the air conditioner negative ion generator protective cover, which will not be elaborated here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
