[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figure 1 , Figure 1 A partial structural diagram of an air conditioning device provided in an embodiment of the utility model, wherein the air conditioning device is provided with a chassis 101, and a drain port 102 is provided on the chassis 101. It is understandable that the air conditioning device may be an electrical appliance such as an air conditioner or a dehumidifier, and the embodiment of the utility model does not limit this. The embodiment of the utility model takes the air conditioning device as an example for explanation.

[0030] Reference Figure 1 As shown, it can be understood that the chassis 101 is arranged below the evaporator 103. When the hot air passes through the evaporator 103, its temperature decreases and then condenses into liquid water. The function of the chassis 101 is to collect and discharge the condensed water generated by the evaporator 103. When the air conditioner is in operation, the evaporator 103 will generate a large amount of condensed water. If it is not discharged in time, it will cause the air conditioner to leak. The chassis 101 is usually designed as an inclined panel to allow water to flow naturally to the drain port 102 to prevent water from being retained in the chassis 101, causing the chassis 101 to overflow or leak.

[0031] However, in some cases, a small amount of accumulated water may still cause fermentation, and microorganisms may produce flocculent sticky substances, which may cause water molecules to gather together to form a water film, and the water film may form a thin film on the surface of the drain outlet 102. The surface tension of this thin film may cause the drain outlet 102 to be blocked. Or there may be other small objects in the bottom plate 101 that stick to the drain outlet 102.

[0032] Reference Figure 1 and Figure 2 As shown, it can be understood that the air conditioning device provided by the embodiment of the utility model includes a dredging component 104, the dredging component 104 is located near the drain outlet 102, and the dredging component 104 includes a dredging piece 105. Figure 1 In the state shown, the dredging member 105 is located outside the drain port 102. At this time, the water in the bottom plate 101 normally flows to the drain port 102 and is discharged outside the air conditioner. Figure 2 In the state shown, the dredging member 105 moves to the drain outlet 102. When there is a water film or a blockage at the drain outlet 102, the dredging member 105 can destroy the water film or push away the blockage, thereby dredging the drain outlet 102 to avoid the hidden danger of water leakage caused by the blockage. After the dredging work is completed, the dredging member 105 can retreat and resume operation. Figure 1Status shown.

[0033] It can be understood that the above-mentioned dredging component 104 has two states, namely a first state and a second state, the first state is the open state of the dredging component 104, and the second state is the closed state of the dredging component 104. In the first state, the dredging member 105 enters the drain port 102 to dredge the drain port 102. In the second state, the dredging member 105 is separated from the drain port 102, and the drain port 102 drains normally.

[0034] It is understandable that in order to enable the dredging assembly 104 to achieve the above two states, the dredging member 105 needs to be driven by a power mechanism to perform telescopic movement along the axis direction of the drain outlet 102. The following technical solutions of power mechanisms may be adopted in the related art.

[0035] In one technical solution, the air conditioning device includes a bottom shell, a guide rail is provided on the bottom shell, the end of the guide rail is arranged corresponding to the drain port 102, and a dredging member 105 is arranged in the guide rail; wherein, when the drain port 102 is detected to be blocked, the dredging member 105 is driven by a motor to move along the guide rail to dredge the drain port 102. The dredging member 105 is in a strip shape, and the dredging member 105 includes a toothed section and a dredging section arranged at the end of the toothed section, and the dredging section is used to dredge the drain port 102. It can be understood that the dredging section is arranged corresponding to the drain port 102. The motor includes a bearing, a driving gear is formed on the bearing, and a toothed structure matched with the driving gear is provided on the toothed section. Through the driving gear and the toothed structure, the motor can drive the dredging member 105 to move along the guide rail. More specifically, a groove is also provided on the toothed section, and a protrusion is provided in the area corresponding to the toothed section on the guide rail, and the groove and the protrusion are engaged, so that the dredging member 105 is installed in the guide rail. It should be noted that in this embodiment, the dredging member 105 is a soft dredging member 105, and the dredging section is formed by bending the end of the tooth-shaped section to match the shape of the guide rail. However, this solution occupies a large space, and the tooth structure on the tooth-shaped section is prone to tooth slippage and breakage, and has low reliability.

[0036] In another technical solution, the air conditioning device includes a linear motor and a bottom shell, a guide rail is provided on the bottom shell, the end of the guide rail is arranged corresponding to the drain port 102, and the dredging member 105 is arranged in the guide rail; the linear motor is connected to the dredging member 105 through a transmission rod, and when the drain port 102 is detected to be blocked, the linear motor drives the dredging member 105 to move along the guide rail through the transmission rod to dredge the drain port 102. Since the linear motor is arranged in the moving direction of the dredging member 105, the space required in the moving direction of the dredging member 105 is relatively large, which is not suitable for equipment with a small internal space.

[0037] Reference Figure 3 and Figure 4As shown, it can be understood that the air conditioning device provided by the embodiment of the utility model includes a driving member 301 and a transmission mechanism, the driving member 301 drives the dredging member 105 to move through the transmission mechanism, the transmission mechanism includes a worm 302, a screw 303 and a worm wheel 304, the worm 302 is meshed with the worm wheel 304, the dredging member 105 and the worm wheel 304 are installed on the screw 303, and the dredging member 105 is located at one end of the screw 303 close to the drain outlet 102. The driving member 301 is connected to the worm 302 and is used to drive the worm 302 to rotate, and the worm 302 rotates and then drives the worm wheel 304 to rotate. The two axes driven by the worm wheel 304 and the worm 302 intersect and are perpendicular to each other. In other words, the driving member 301 is set along the first direction, and the clearing member 105 moves along the second direction. The first direction is perpendicular to the second direction. By changing the transmission direction, the space required for the driving member 301 in the movement direction of the clearing member 105 is saved, thereby increasing the stroke of the clearing member 105 and achieving a better clearing effect.

[0038] Reference Figure 3 and Figure 4 As shown, it can be understood that the dredging component 104 also includes a fixing seat 305, and the fixing seat 305 can be fixed to the chassis 101, or fixed to other parts of the housing of the air conditioning equipment. The fixing seat 305 includes a first fixing portion 306, and the first fixing portion 306 is provided with a threaded hole 401. The screw rod 303 is inserted into the threaded hole 401, and the threaded hole 401 cooperates with the screw rod 303, so that the dredging member 105 can rotate while moving toward the drain outlet 102, so that the dredging member 105 can rotate with the dredging member while pushing the blockage, thereby enhancing the dredging effect. However, the solution of a linear motor pushing the dredging member 105 and the solution of a gear rack pushing the dredging member 105 can only push the blockage, but cannot rotate with the blockage.

[0039] Reference Figure 3 and Figure 4As shown, it can be understood that the fixing seat 305 includes a second fixing portion 307, and the second fixing portion 307 is provided with a receiving cavity 402, which is cylindrical, and the worm 302 is located in the receiving cavity 402, and the receiving cavity 402 allows the worm 302 to rotate therein, and the second fixing portion 307 can protect the worm 302, because the gear parts must be coated with silicone grease, and the second fixing portion 307 can try to prevent dust from falling on the worm 302 and contaminating the silicone grease. The peripheral wall of the second fixing portion 307 is provided with a connecting hole 403, and the connecting hole 403 penetrates the peripheral wall of the second fixing portion 307 to communicate with the receiving cavity 402, and the worm wheel 304 meshes with the worm 302 after passing through the connecting hole 403. The second fixing part 307 is connected to the first fixing part 306, and the second fixing part 307 and the first fixing part 306 are an integral injection molding structure. A special mold is designed and manufactured, the raw material is placed in the mold, and then the material is molded into a fixing seat 305 by heating, pressurizing, injection molding, etc. The integral molding technology can greatly shorten the production cycle and improve production efficiency, because all parts are completed in one step, without the cumbersome procedures of multiple steps. The integral molding technology can reduce production costs, because all parts are completed in the same mold, there are no steps of mold separation and splicing, saving mold costs and production time. The integrally molded product or component has high overall strength and is not prone to breakage or damage because there is no trace of splicing or welding. Since there is no process of assembling multiple parts, the integrally molded product or component has higher reliability, reduces the risk of assembly errors or part mismatches, and ensures the installation accuracy of the worm wheel 304 and the worm 302. In addition, the integrally molded product or component has a neat and beautiful appearance, no traces of splicing or welding, and improves the overall quality of the product.

[0040] It should be noted that, in some other embodiments, the second fixing portion 307 and the first fixing portion 306 may also be a split structure, both of which are respectively connected to the chassis 101 or the casing of the air conditioning equipment, or the second fixing portion 307 and the first fixing portion 306 are connected by screws.

[0041] Reference Figure 3 and Figure 4As shown, it can be understood that the second fixing part 307 is cylindrical, the first fixing part 306 is box-shaped, the first fixing part 306 is connected to the outer wall of the second fixing part 307, and the first fixing part 306 is located below the second fixing part 307, and the connection hole 403 on the second fixing part 307 is opened downward. The first fixing part 306 can cover the side of the worm wheel 304 facing the dredging member 105, and can also cover the two sides of part of the worm wheel 304 arranged along the axis direction of the second fixing part 307, and cover the lower side of part of the worm wheel 304, while the second fixing part 307 can cover the upper side of the worm wheel 304. At this time, the side of the worm wheel 304 away from the dredging member 105 is open, mainly to leave enough operating space for the convenience of installing components such as the worm wheel 304 and the screw rod 303. However, when the dredging component 104 is working, this partially open space will cause impurities such as moisture and dust to enter, so this space is needed. The closed worm wheel 304 can prevent external factors such as dust and oil from damaging the surface of the worm wheel 304 , thereby effectively extending the service life of the worm wheel 304 .

[0042] Reference Figure 3 and Figure 4 As shown, it can be understood that the dredging component 104 also includes a fixed cover 308, and the fixed cover 308 and the first fixing part 306 are jointly arranged around the outer periphery of the worm wheel 304, that is, the fixed cover 308 mainly covers the side of the worm wheel 304 away from the dredging member 105. Of course, the fixed cover 308 can also cover the two sides of the worm wheel 304 arranged along the axial direction of the second fixing part 307, and cover part of the lower side of the worm wheel 304, so that the angle of covering the worm wheel 304 is more comprehensive, which helps to extend the service life of the worm wheel 304. The fixed cover 308 is installed on the fixing seat 305. For example, the upper end of the fixed cover 308 is welded or bonded to the second fixing part 307, so that the gap between the fixed cover 308 and the fixing seat 305 is smaller, and the sealing effect is improved.

[0043] It can be understood that in order to save installation space and make the structure more compact, the fixed cover 308 should be as close to the fixed seat 305 as possible, that is, in the direction of movement of the dredging member 105, the distance between the fixed cover 308 arranged on the opposite sides of the worm gear 304 along the axis of the screw rod 303 and the first fixed portion 306 should be as small as possible. At this time, the fixed cover 308 may block the movement of the screw rod 303. Therefore, the fixed cover 308 is provided with a through hole 309 at the position corresponding to the screw rod 303. The diameter of the through hole 309 is larger than the maximum diameter of the screw rod 303. Therefore, the through hole 309 can allow the screw rod 303 to pass through. Figure 1 By providing a through hole 309 in the fixed cover 308 to allow the screw rod 303 to pass through, the overall structure of the dredging component 104 can be made more compact, the occupied space can be reduced, and the normal use of the dredging component 104 can be not affected, so that it can be better applied to equipment with smaller internal space.

[0044] Reference Figure 4 As shown, it can be understood that the dredging component 104 also includes a sealing cover 404, which is arranged at the connection between the driving member 301 and the worm 302, that is, the sealing cover 404 is sleeved on the worm 302, and the sealing cover 404 is provided with a spiral groove matched with the worm 302, and the sealing cover 404 is located at one end of the worm 302 close to the driving member 301. The sealing cover 404 is arranged as a whole on the outside of the second fixing part 307 and connected to the end of the second fixing part 307. The sealing cover 404 includes a first sealing part 405 and a second sealing part 406, the outer diameter of the first sealing part 405 is larger than the outer diameter of the second sealing part 406, and the first sealing part 405 abuts on the end of the second fixing part 307, which can prevent impurities such as moisture and dust from entering the accommodating cavity 402. The second sealing part 406 is close to the driving member 301 and is mainly used to protect the driving member 301.

[0045] It is understandable that the purpose of designing the sealing cover 404 is mainly to provide sealing and protection to prevent moisture, dust and other impurities from entering the interior of the driver 301, thereby ensuring the normal operation of the driver 301 and extending its service life. For example, the driver 301 can be a motor, and the internal components of the motor are made of many metal materials. Moisture entering the interior of the motor may cause the internal components of the motor to rust and corrode, thereby affecting the normal operation and service life of the motor. The sealing cover 404 can effectively prevent moisture from entering the interior of the motor. Dust and other impurities entering the interior of the motor may affect the heat dissipation effect of the motor, and may also cause wear and damage to the internal components of the motor, thereby affecting the performance and service life of the motor. The sealing cover 404 can effectively prevent dust and other impurities from entering the interior of the motor.

[0046] It should be noted that, in some other embodiments, the worm 302 and the worm wheel 304 can also have other installation methods. For example, the dredging member 105 is installed on the worm 302, and a bearing is installed on the worm 302, and the worm 302 is installed on the chassis 101 or installed on the housing of the air conditioning device through the bearing. The driving member 301 is connected to the worm wheel 304, and the driving member 301 drives the worm wheel 304 to rotate, and then the worm wheel 304 transmits power to the worm 302, and the worm wheel 304 only rotates while the position remains unchanged. While the worm 302 rotates, it can move along the axis direction of the worm 302. Therefore, the worm 302 can drive the dredging member 105 to advance and retreat along the axis of the drain outlet 102, and can also drive the dredging member 105 to rotate around the axis of the drain outlet 102, so that it can rotate with the blockage while pushing the blockage, thereby enhancing the dredging effect.

[0047] It is understandable that the dredging piece 105 is made of rubber material, and the rubber material has good wear resistance and can resist friction and wear. The dredging piece 105 of the embodiment of the utility model has the characteristics of linear motion and rotational motion when working, and has more friction with the inner wall or edge of the drain port 102, requiring the dredging piece 105 to have good wear resistance, so the rubber material is suitable for manufacturing the dredging piece 105 of the embodiment of the utility model. In addition, the rubber material has good elasticity and can absorb shock and vibration. In order to better dredge the drain port 102, the dredging piece 105 needs to be squeezed and contacted with the inner wall or edge of the drain port 102. When the dredging piece 105 has good elasticity, it can better allow the dredging piece 105 to enter the drain port 102 and reduce the resistance to advancement. In particular, when the position of the dredging member 105 and the drain outlet 102 is misaligned due to manufacturing errors, assembly errors, etc., if the dredging member 105 is a rigid member, the dredging member 105 cannot enter the drain outlet 102 for dredging. If the dredging member 105 has good elasticity, it can enter the drain outlet 102 for dredging by extrusion deformation. In addition, the rubber material has good corrosion resistance and can resist the erosion of various chemical substances. When a small amount of water accumulates in the chassis 101, causing fermentation, and microorganisms produce corrosive chemical substances, the dredging member 105 will come into contact with the chemical substances. The dredging member 105 made of rubber material can increase the service life.

[0048] Reference Figure 3 and Figure 4 As shown, it can be understood that the dredging member 105 includes a mounting portion 310, a connecting portion 311 and a dredging portion 312. The mounting portion 310 is columnar, and the dredging portion 312 is cylindrical. The mounting portion 310 is used to connect the screw rod 303, and the dredging portion 312 is arranged around the outer periphery of the mounting portion 310. The dredging portion 312 is used to destroy the water film formed by impurities or push away the blockage. The connecting portion 311 connects the mounting portion 310 and the dredging portion 312, and allows the mounting portion 310 and the dredging portion 312 to have a gap in the direction perpendicular to the axis of the screw rod 303. When the dredging portion 312 contacts the inner wall of the drain port 102 or contacts other harder objects, the dredging portion 312 can shrink inward to avoid, reduce the resistance encountered by the dredging member 105 when it moves forward, and also provide avoidance protection for the dredging member 105. In addition, the gap between the mounting portion 310 and the dredging portion 312 in the direction perpendicular to the axis of the screw rod 303 can also increase the elasticity of the dredging portion 312, allowing the dredging portion 312 to better fit the inner wall of the drain outlet 102. In other words, compared with the solid structure of the dredging member 105, Figure 3 and Figure 4 The shown clearing piece 105 can save materials and reduce costs on one hand, and can also reduce the resistance encountered by the clearing piece 105 when moving forward on the other hand, thereby providing avoidance protection for the clearing piece 105.

[0049] Reference Figure 3As shown, it can be understood that the outer diameter of the dredging portion 312 gradually increases in the direction close to the transmission mechanism, that is, the dredging portion 312 is in a frustum shape, and the cross-sectional area of ​​the end of the dredging portion 312 close to the drain outlet 102 is smaller than the cross-sectional area of ​​the end of the dredging portion 312 away from the drain outlet 102. When the dredging member 105 moves toward the drain outlet 102, the smaller end of the dredging portion 312 first enters the drain outlet 102, and then the portion of the dredging portion 312 that is substantially equal to the inner wall diameter of the drain outlet 102 contacts the inner wall of the drain outlet 102, which facilitates the dredging member 105 to find the position of the drain outlet 102 and enter the drain outlet 102 more easily, avoiding the problem that the cylindrical dredging member 105 is blocked outside the drain outlet 102, that is, the conical structure allows the dredging member 105 to more easily penetrate into the drain outlet 102, which is convenient for cleaning.

[0050] Reference Figure 1 and Figure 2 As shown, it can be understood that the drainage direction of the drain outlet 102 is set to be inclined downward. Due to the effect of gravity, water will naturally flow downward. The inclined drain outlet 102 can better utilize the effect of gravity to drain water more quickly and improve drainage efficiency. The inclined drain outlet 102 can avoid water accumulation at the drain outlet 102, prevent the breeding of bacteria and dirt, and keep the drainage system clean and sanitary. The inclined drain outlet 102 can better utilize the flushing effect of the water flow during cleaning, making the drain outlet 102 easier to clean. The inclined drain outlet 102 can reduce the accumulation of debris and dirt at the drain outlet 102, prevent the occurrence of blockage, and ensure the smooth flow of the drainage system.

[0051] Reference Figure 1 and Figure 2 As shown, it can be understood that a guide portion 106 is provided at the edge of the drain port 102, and the diameter of the end of the guide portion 106 close to the transmission mechanism is the largest, and the diameter of the end of the guide portion 106 away from the transmission mechanism is the smallest, and is equal to the inner wall diameter of the drain port 102. By providing the guide portion 106, it is convenient for the dredging member 105 to move along the inner wall surface of the guide portion 106, thereby guiding the dredging member 105 to enter the drain port 102. The guide portion 106 can be a chamfer or rounded corner at the edge of the drain port 102, and the chamfer can make the drainage orifice smoother, reduce the resistance of the water flow when it is discharged, and make the water flow discharge more smoothly. The chamfered design can make the drainage orifice more inclined, thereby avoiding water accumulation at the orifice. This can prevent the growth of bacteria and dirt, and keep the drainage system clean and hygienic.
