Description

Technical Field

[0001] This utility model belongs to the technical field of snow removal devices, specifically relating to a snow removal device, a fan, and an air conditioner. Background Technology

[0002] In cold regions, frequent snowfall in winter can severely impact transportation and daily life. Common methods for removing snow from vehicles rely mainly on manual labor and machinery, which are often insufficient for timely and convenient snow removal. Vehicles are frequently left outdoors, and vehicle air conditioners are typically installed on the roof. In snowy conditions, snow can easily accumulate on the surface of the air conditioner, clogging the fan and preventing it from rotating. This can easily damage the air conditioner.

[0003] To overcome the above problems, this utility model provides a snow-blocking mechanism on the outside of the air conditioner fan to prevent snow from accumulating on the fan blades; and uses a guide channel in the snow-blocking mechanism to guide the melted snow to prevent the air conditioner fan from becoming blocked and unable to rotate. Utility Model Content

[0004] The purpose of this utility model is to address the problems of existing common vehicle snow removal methods, which mainly rely on manual and mechanical methods and often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often placed in the outdoor environment, while vehicle air conditioners are usually installed on the roof of the vehicle. In the case of snow in the outdoor environment, snow easily accumulates on the surface of the vehicle air conditioner, which can block the air conditioner fan, prevent the air conditioner fan from rotating, and easily damage the air conditioner. The present invention provides a snow removal device, a fan, and an air conditioner.

[0005] On the one hand, this utility model provides a snow removal device, including a housing covering the outside of a fan, and a snow blocking mechanism inside the housing to prevent snow from accumulating on the fan blades; the snow blocking mechanism is provided with a guide groove, and the housing is provided with a guide port communicating with the guide groove;

[0006] When in use, the snow on the snow-blocking mechanism melts and flows out from the guide port through the guide channel.

[0007] When using the snow removal device provided by this utility model, the housing is placed outside the fan. When it snows, the snow-blocking mechanism inside the housing catches the falling snow, preventing snow accumulation on the fan surface, which could cause fan blockage, prevent the fan from rotating, and ultimately damage the air conditioner. After the snow melts, the melted water can flow out through the guide channel in the snow-blocking mechanism. The snow removal device provided by this utility model can prevent snow accumulation simply by installing a snow-blocking mechanism inside the housing. It has a simple structure, low energy consumption, and is characterized by high efficiency, environmental friendliness, and low maintenance costs.

[0008] Furthermore, the shell is a frame structure.

[0009] In the snow removal device provided by this utility model, the shell is a frame structure with openings at the top and bottom and enclosed on all four sides. The frame shape can be circular or square; to facilitate the installation of the snow-blocking mechanism and mass production, a square frame structure is preferred in this utility model. In use, one end of the shell is placed on the outside of the fan, which is the bottom end, and the opposite end is the top end. The snow-blocking mechanism is installed inside the shell, and the opening at the top of the shell ensures ventilation for the air conditioning fan.

[0010] Furthermore, the snow-blocking mechanism includes a baffle, and a flow channel is formed on the baffle.

[0011] Furthermore, the guide channel is opened along the axial direction of the baffle.

[0012] In the snow removal device provided by this utility model, the guide channel is mainly used for the snow water to flow out through the guide port after the snow melts. Its layout position and cross-sectional shape are not limited. It can be curved, parallel to the baffle or opened along the axial direction. This utility model adopts the method of opening along the two sides of the baffle along the axial direction.

[0013] Furthermore, the snow-blocking mechanism includes at least two baffles, and all the baffles are staggered.

[0014] In the snow removal device provided by this utility model, the snow-blocking mechanism includes at least two baffles, which are arranged in a staggered manner. On the one hand, this arrangement can catch more falling snow in the horizontal direction, preventing snow from falling onto the fan blades and affecting its normal operation. On the other hand, this structural layout can reduce the impact of the baffles on the ventilation volume of the air conditioning fan. To ensure the ventilation volume of the air conditioning fan, there is an optimal distance between the bottom baffle and the fan, between the upper and lower baffles, and between baffles in the same layer. In actual working conditions, these three optimal distances can be adjusted according to the actual dimensions. This utility model has the advantage of protecting the ventilation volume of the air conditioning system while having snow removal capabilities. Furthermore, the snow removal device provided by this utility model is lightweight, convenient, easy to mass-produce, and highly adaptable.

[0015] Furthermore, in the arrangement direction of the baffles, at least one baffle has its edge abutting against the inner wall of the housing.

[0016] In the snow removal device provided by this utility model, the housing covers the outside of the fan, and a snow-blocking mechanism is installed inside the housing. The snow-blocking mechanism can catch falling snow and prevent snow from accumulating on the surface of the fan. The snow-blocking mechanism includes at least two baffles, which are arranged in a staggered manner. In the baffle arrangement direction, at least one baffle is installed close to the inner wall of the housing on both sides of the edge. This installation can prevent falling snow from falling onto the fan blades along the inner wall of the housing, thereby affecting its normal operation.

[0017] Furthermore, a heating film is provided on the baffle.

[0018] Furthermore, the baffle is made of metal.

[0019] Furthermore, the baffle is an aluminum plate, and the heating film is an electric heating film.

[0020] In the snow removal device provided by this utility model, the baffle is made of a metal material with high rigidity, hardness, and good thermal conductivity, preferably aluminum; the heating film is further selected as an electric heating film, which can adhere more firmly to the metal baffle. When the vehicle's air conditioning is turned on, if there is snow accumulated on the baffle of the snow removal device provided by this utility model, it can automatically identify and activate the electric heating film. Because the metal material has good thermal conductivity, the baffle can be heated quickly, thereby causing the snow on the baffle to melt quickly, achieving the purpose of rapid snow removal. After the snow melts, it flows out through the guide channel and guide port. The snow removal device provided by this utility model can activate the electric heating film at any time as needed to quickly remove snow. This utility model has the advantages of high efficiency and environmental protection.

[0021] Furthermore, the heating film is disposed on the inner and / or outer side of the baffle.

[0022] In the snow removal device provided by this utility model, the heating film is adhered to the surface of the baffle, on the inner and / or outer sides. Preferably, from the perspective of aesthetics and protection, the heating film is adhered to the inner side of the baffle, which is the side of the baffle facing the fan.

[0023] Furthermore, the bottom surface of the guide channel is horizontally arranged, and both ends of the guide channel are connected to guide ports.

[0024] Furthermore, the bottom surface of the guide channel is inclined, and the lower end of the guide channel is connected to a guide port.

[0025] In the snow removal device provided by this utility model, the guide channel is mainly used to allow melted snow water to flow out through the guide port after the snow melts. The bottom surface of the guide channel is inclined, allowing the melted snow water to flow more quickly along the inclined guide channel to the guide port. This structural design increases the guiding capacity of the guide channel.

[0026] Furthermore, the bottom surface of the guide channel is high in the middle and low at both ends, and both ends of the guide channel are connected to guide ports.

[0027] In the snow removal device provided by this utility model, the guide channel is mainly used to allow melted snow water to flow out through the guide port after the snow melts. The bottom surface of the guide channel is designed to be high in the middle and low at both ends, so that the melted snow water can flow more quickly along the inclined guide channel to the guide port. This structural design can increase the guiding capacity of the guide channel.

[0028] Furthermore, the cross-sectional shape of the guide channel is V-shaped or U-shaped.

[0029] In the snow removal device provided by this utility model, the melted snow water flows out from the guide port along the guide channel. The main function of the guide channel is to guide the snow water. Its internal shape does not affect the guidance of the snow water. This utility model uses the commonly used V-shaped or U-shaped design in industry.

[0030] On the other hand, the present invention also provides a fan, including the fan and the above-mentioned snow removal device, wherein the housing of the snow removal device is disposed on the outside of the fan.

[0031] Since the fan provided by this utility model includes the aforementioned snow removal device, when the fan is in use, the housing of the snow removal device is placed outside the fan. When it snows in the external environment, the snow-blocking mechanism inside the housing catches the falling snow, preventing snow accumulation on the fan surface, which could cause fan blockage, prevent the fan from rotating, and thus damage the air conditioner. After the snow melts, the snow water can flow out through the guide port along the guide channel in the snow-blocking mechanism. The snow-blocking mechanism includes at least two baffles, all of which are staggered vertically. This arrangement ensures that the fan's ventilation volume is not affected. An electric heating film is attached to the inner side of the baffle. When the air conditioner is started and detects snow accumulation on the baffle surface, the electric heating film can be automatically activated to heat the baffle, causing the snow on the baffle to melt quickly, thus achieving the purpose of quickly clearing the snow. The bottom of the guide channel can be set to be horizontal, inclined, or high in the middle and low at both ends. When the bottom of the guide channel is set to be inclined, the guide channel's ability to guide snow water is stronger. The fan provided by this utility model first avoids the problem of snow accumulation through structural layout, and then quickly melts the snow by installing an electric heating film heating baffle to achieve the purpose of quickly clearing the snow. This utility model has a simple structure, low energy consumption, and can carry out snow removal work at any time as needed.

[0032] Furthermore, this utility model also provides an air conditioner, including the aforementioned fan.

[0033] Since the air conditioner provided by this utility model includes the aforementioned fan, when the air conditioner is in use, the snow removal device housing is installed outside the fan. When it snows in the external environment, the snow-blocking mechanism inside the housing catches the falling snow, preventing snow accumulation on the fan surface, which could cause fan blockage, prevent the fan from rotating, and thus damage the air conditioner. After the snow melts, the snow water can flow out through the guide port along the guide channel in the snow-blocking mechanism. The snow-blocking mechanism includes at least two baffles, all of which are staggered vertically. This arrangement ensures that the fan's ventilation volume is not affected. An electric heating film is attached to the inner side of the baffle. When the air conditioner is started and detects snow accumulation on the baffle surface, the electric heating film can be automatically activated to heat the baffle, causing the snow on the baffle to melt quickly, thus achieving the purpose of quickly clearing the snow. The bottom of the guide channel can be set to be horizontal, inclined, or high in the middle and low at both ends. When the bottom of the guide channel is set to be inclined, the guide channel's ability to guide snow water is stronger. The air conditioner provided by this utility model first avoids the problem of snow accumulation through structural layout, and then quickly melts the snow by installing an electric heating film heating baffle to achieve the purpose of quickly clearing the snow. This utility model has a simple structure, low energy consumption, and can carry out snow removal work at any time as needed.

[0034] The beneficial effects of this utility model are as follows:

[0035] In the snow removal device provided by this utility model, a housing is installed on the outside of the blower, and a snow-blocking mechanism is provided inside the housing. This snow-blocking mechanism is used to prevent snow from falling onto the blower blades. The snow-blocking mechanism has a guide groove, and a guide port connected to the guide groove is opened on the housing. During use, the snow on the snow-blocking mechanism melts and flows out through the guide groove and guide port. The structural layout avoids snow accumulation on the surface of the blower.

[0036] Furthermore, the snow removal device provided by this utility model includes at least two baffles arranged vertically and vertically in a staggered manner. There is a certain gap between the fan and the bottom baffle, as well as between the baffles in the same layer and between the upper and lower baffles. This gap, combined with the top-opening shell, ensures the ventilation volume of the air conditioning fan. Simultaneously, a heating film is adhered to the inner side of the baffles. When the vehicle's air conditioning is activated, if snow accumulates on the baffles of the snow removal device, it can automatically identify and activate the heating film. As a metal material, the baffles can quickly conduct heat, thereby melting the snow. After melting, the snow flows out from the guide port along the guide channel, thus achieving the purpose of quickly melting and clearing the snow.

[0037] Compared with existing vehicle snow removal methods, the snow removal device provided by this utility model can carry out snow removal work at any time and in a timely manner, no longer relying on manual or other mechanical operations. It is timely and efficient, and at the same time, it has a simple structure, low energy consumption, is easy to mass-produce and has low maintenance costs. It is suitable for various vehicle-mounted roof snow removal devices. Attached Figure Description

[0048] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0049] Example 1

[0050] To address the issues that existing common vehicle snow removal methods mainly rely on manual and mechanical methods, which often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often left in outdoor environments, and vehicle air conditioners are commonly installed on the roof of vehicles, snow easily accumulates on the surface of the air conditioner in snowy conditions, clogging the air conditioner fan, causing the fan to malfunction and potentially damaging the air conditioner, this embodiment 1 provides a snow removal device. This device consists of a housing covering the outside of the fan, with a snow-blocking mechanism installed inside. This snow-blocking mechanism prevents snow from falling onto the fan blades. The snow-blocking mechanism has a guide channel, and the housing has a guide port communicating with the guide channel. During use, the snow on the snow-blocking mechanism melts and flows out through the guide channel and guide port, thus preventing snow accumulation, clogging the air conditioner fan, preventing the fan from rotating, and ultimately damaging the air conditioner.

[0051] like Figures 1 to 6 As shown, the snow removal device provided in this embodiment 1 includes a housing 1 and a snow blocking mechanism 7.

[0052] In this embodiment 1, the bottom of the housing 1 covers the outside of the fan, and a snow-blocking mechanism 7 is installed inside the housing 1. When it snows in the external environment, the snow-blocking mechanism 7 is used to prevent snow from falling onto the fan blades. The top of the housing 1 is open. The snow-blocking mechanism 7 is also provided with a guide channel, and a guide port 3 communicating with the guide channel is opened on the housing 1. When the snow on the snow-blocking mechanism 7 melts, it flows out from the guide port 3 through the guide channel.

[0053] In this embodiment 1, by installing a snow-blocking mechanism 7 inside the housing 1, external snow can be caught at any time to prevent snow from accumulating on the fan blades, thus ensuring that the normal operation of the fan is not affected by snow accumulation.

[0054] like Figure 1 As shown, in this embodiment 1, the snow-blocking mechanism 7 includes at least two baffles 2, which are staggered vertically. This arrangement allows for more comprehensive snow catchment in the arrangement direction. The staggered arrangement also creates a certain distance between all the baffles 2, allowing for ventilation. Simultaneously, in the arrangement direction of the baffles 2, at least one baffle 2 is installed close to the inner wall of the housing 1 to prevent snow from falling onto the fan blades along the inner wall of the housing 1. To ensure the ventilation volume of the air conditioning fan and the snow removal capacity of this embodiment 1, there is an optimal distance between the bottom baffle 2 and the fan blades, the distance between baffles 2 in the same layer, and the distance between upper and lower baffles 2. In actual working conditions, this distance can be adjusted according to the actual dimensions. Embodiment 1 has a simple structure and strong adaptability.

[0055] To further clear snow accumulation, in this embodiment 1, a heating film 6 is adhered to the surface of the baffle 2. For aesthetic and protective purposes, in this embodiment 1, the heating film 6 is adhered to the inner wall of the baffle 2, specifically the inner wall facing the fan. The baffle 2 is made of a metal material with high rigidity, hardness, and good thermal conductivity. When the vehicle's air conditioning is activated, if snow accumulation is detected on the snow-blocking mechanism 7, the heating film 6 can be automatically activated. Due to the thermal conductivity of the metal material, the baffle 2 will be rapidly heated, thus melting the snow on the baffle 2. This embodiment 1 first prevents snow accumulation on the fan blades through structural layout, and then achieves rapid snow clearing by installing the heating film 6 on the baffle 2. This allows for timely and effective snow melting for the roof-mounted air conditioning system in cold regions or snowy outdoor environments.

[0056] Furthermore, the baffle can be an aluminum plate, and the heating film can be an electric heating film. In this embodiment 1, the baffle 2 is made of a metal material with high rigidity, hardness and good thermal conductivity, preferably aluminum; the heating film is further selected as an electric heating film, which can be more firmly adhered to the baffle 2.

[0057] In this embodiment 1, the housing 1 is preferably a frame structure. Specifically, the housing 1 can be a frame structure with openings at the top and bottom and enclosed on all four sides. The frame shape can be circular or square. To facilitate the installation and mass production of the snow-blocking mechanism 7, a square frame structure is preferred in this embodiment 1. In use, the end of the housing 1 that covers the outside of the fan 4 is called the bottom end, and the opposite end is called the top end. The snow-blocking mechanism 7 is installed inside the housing 1, and the opening at the top of the housing 1 ensures ventilation for the air conditioning fan.

[0058] In this embodiment 1, the bottom surface of the guide channel 8 is arranged horizontally, as follows: Figure 7 As shown, a guide channel 8 is opened on both sides of the edge of the baffle 2 along the axial direction. Both ends of the guide channel 8 are connected to the guide port 3. When the snow melts, it can flow out along the guide channel 8 to the guide port 3 at both ends.

[0059] In this embodiment 1, at least one baffle 1 has its edge abutting against the inner wall of the housing 1 in the arrangement direction of the baffles 2. The housing 1 covers the outside of the fan 4, and a snow-blocking mechanism 7 is installed inside the housing 1. The snow-blocking mechanism 7 can catch falling snow and prevent snow from accumulating on the surface of the fan 4. In the arrangement direction of the baffles 2, at least one baffle 1 is installed against the inner wall of the housing 1 on both sides of the edge. This installation arrangement can prevent falling snow from falling along the inner wall of the housing 1 onto the fan blades of the fan 4, thereby affecting its normal operation.

[0060] Example 2

[0061] To address the issues that existing common vehicle snow removal methods mainly rely on manual and mechanical methods, which often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often left in outdoor environments, and vehicle air conditioners are commonly installed on the roof of vehicles, snow easily accumulates on the surface of the air conditioner in snowy conditions, clogging the air conditioner fan, causing the fan to malfunction and potentially damaging the air conditioner, this embodiment 2 provides a snow removal device. This device consists of a housing covering the outside of the fan, with a snow-blocking mechanism installed inside. This snow-blocking mechanism prevents snow from falling onto the fan blades. The snow-blocking mechanism has a guide channel, and the housing has a guide port communicating with the guide channel. During use, the snow on the snow-blocking mechanism melts and flows out through the guide channel and guide port, thus preventing snow accumulation, clogging the air conditioner fan, preventing the fan from rotating, and ultimately damaging the air conditioner.

[0062] The snow removal device provided in this embodiment 2 differs from the snow removal device provided in embodiment 1 in that the bottom surface of the guide channel 8 in this embodiment 2 is arranged at an angle.

[0063] like Figure 7As shown, the bottom surface of the guide channel 8 is inclined, with one end higher than the other. The lower end is connected to the guide port 3, and the melted snow water flows out from the guide port 3 at the lower end.

[0064] Example 3

[0065] To address the issues that existing common vehicle snow removal methods mainly rely on manual and mechanical methods, which often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often left in outdoor environments, and vehicle air conditioners are commonly installed on the roof of vehicles, snow easily accumulates on the surface of the air conditioner in snowy conditions, clogging the air conditioner fan, causing the fan to malfunction and potentially damaging the air conditioner, this embodiment 3 provides a snow removal device. This device consists of a housing covering the outside of the fan, with a snow-blocking mechanism installed inside. This snow-blocking mechanism prevents snow from falling onto the fan blades. The snow-blocking mechanism has a guide channel, and the housing has a guide port communicating with the guide channel. During use, the snow on the snow-blocking mechanism melts and flows out through the guide channel and guide port, thus preventing snow accumulation, clogging the air conditioner fan, preventing the fan from rotating, and ultimately damaging the air conditioner.

[0066] The snow removal device provided in this embodiment 3 differs from the snow removal device provided in embodiment 1 in that the bottom surface of the guide channel 8 in this embodiment 3 is high in the middle and low at both ends.

[0067] like Figure 8 As shown, the bottom surface of the guide channel 8 is high in the middle and low at both ends. Both ends of the guide channel 8 are connected to the guide port 3. This method can make the guide channel 8 more effective.

[0068] Example 4

[0069] To address the issues that existing common vehicle snow removal methods mainly rely on manual and mechanical methods, which often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often left in outdoor environments, and vehicle air conditioners are commonly installed on the roof of vehicles, snow easily accumulates on the surface of the air conditioner in snowy conditions, clogging the air conditioner fan, causing the fan to malfunction and potentially damaging the air conditioner, this embodiment 4 provides a fan. This fan is covered by a housing, inside which a snow-blocking mechanism is installed. This snow-blocking mechanism prevents snow from falling onto the fan blades. The snow-blocking mechanism has a guide channel, and the housing has a guide port communicating with the guide channel. During use, the snow on the snow-blocking mechanism melts and flows out through the guide channel and guide port, thus preventing snow accumulation, clogging the air conditioner fan, preventing the fan from rotating, and ultimately damaging the air conditioner.

[0070] The fan provided in this embodiment 4 includes a fan 4 and a snow removal device described in any of embodiments 1 to 3.

[0071] Since the fan provided in Embodiment 4 includes any of the snow removal devices described in Embodiments 1 to 3, the fan provided in Embodiment 4 can be used by covering the outside of the fan 4 with a housing 1. The top of the housing 1 is open, and a snow-blocking mechanism 7 is installed inside the housing 1. This snow-blocking mechanism 7 is used to prevent snow from falling onto the fan blades. A guide groove 8 is provided on the snow-blocking mechanism 7, and a guide port 3 communicating with the guide groove 8 is opened on the housing 1. When the snow melts, it flows out from the guide port 3 along the guide groove 8. The snow-blocking mechanism 7 includes at least two baffles 2, and all the baffles 2 are arranged vertically in a staggered manner. The arrangement allows for greater horizontal obstruction of the fan blades 4, and the staggered arrangement ensures adequate ventilation for the fan while maintaining snow removal capability. Furthermore, a heating film 6, an electrically heated film, is adhered to the inner side of the baffle 2. This film is securely attached to the metal baffle 2. When the vehicle's air conditioning is activated, if snow accumulates on the baffle 2, the heating film is automatically activated. Because the baffle 2 has excellent thermal conductivity, the heating film 6 quickly transfers heat to the snow accumulation, causing it to melt rapidly and flow out through the guide channel 8 and guide port 3. This structural layout physically prevents snow accumulation on the fan blades, and the heating film 6 on the baffle 2 quickly clears the snow, thus solving the problem of snow accumulation on the air conditioning surface, which can clog the air conditioning fan, prevent it from rotating, and damage the air conditioning system. This embodiment 4 is characterized by high efficiency and environmental friendliness.

[0072] Example 5

[0073] To address the issues that existing common vehicle snow removal methods mainly rely on manual and mechanical methods, which often cannot remove snow in a timely and convenient manner, and the fact that vehicles are often left in outdoor environments, and vehicle air conditioners are commonly installed on the roof of vehicles, snow easily accumulates on the surface of the air conditioner in snowy conditions, clogging the air conditioner fan, causing the fan to malfunction and potentially damaging the air conditioner, this embodiment 5 provides an air conditioner that uses a housing to cover the outside of the air conditioner fan. Inside the housing, a snow-blocking mechanism is installed to prevent snow from falling onto the fan blades. The snow-blocking mechanism has a guide channel, and the housing has a guide port communicating with the guide channel. During use, the snow on the snow-blocking mechanism melts and flows out through the guide channel and guide port, thus preventing snow accumulation, clogging of the air conditioner fan, and ultimately, damage to the air conditioner.

[0074] This embodiment 5 also provides an air conditioner, including an outdoor unit 5 and the fan from embodiment 4.

[0075] Since the air conditioner provided in Embodiment 5 includes the fan in Embodiment 4, the fan provided in Embodiment 5 can be used by covering the outside of the fan 4 with the housing 1. The top of the housing 1 is open, and a snow-blocking mechanism 7 is installed inside the housing 1. This snow-blocking mechanism 7 is used to prevent snow from falling onto the fan blades. The snow-blocking mechanism 7 is provided with a guide groove 8, and a guide port 3 communicating with the guide groove 8 is opened on the housing 1. When the snow melts, it flows out from the guide port 3 along the guide groove 8. The snow-blocking mechanism 7 includes at least two baffles 2, and all the baffles 2 are arranged vertically in a staggered manner. This arrangement can... The horizontal obstruction of the fan blades 4 and the staggered arrangement ensure that the snow removal device can guarantee the fan's ventilation volume while still having snow removal capabilities. Furthermore, a heating film 6 is adhered to the inner side of the baffle 2. This heating film 6 is an electric heating film, which can be firmly adhered to the metal baffle 2. When the vehicle's air conditioning is started, if there is snow accumulation on the baffle 2, it can automatically identify and activate the heating film. Because the baffle 2 has good thermal conductivity, when the heating film 6 is activated, it can quickly transfer heat to the snow accumulation, causing the snow to melt rapidly and flow out from the guide port 3 along the guide groove 8. Firstly, the structural layout physically prevents snow accumulation on the fan blades. Secondly, by setting the heating film 6 on the baffle 2 to quickly clear the snow, this solves the problem of snow accumulation on the air conditioning surface, which can clog the air conditioning fan, prevent the fan from rotating, and easily damage the air conditioning system. This embodiment 5 is characterized by high efficiency and environmental friendliness.
