Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and more specifically, to a dual-fan air guide driving device and method for a duct fan. Background Art

[0002] Duct air conditioner, full name is duct air conditioning unit, is a part of a central air conditioning system. It is usually used for air conditioning in large spaces such as commercial buildings, office buildings, shopping malls, hospitals, schools, etc. Duct air conditioner delivers processed air to various rooms or areas through pipes (ducts) to achieve the purpose of cooling, heating, ventilation and air purification. The indoor unit of the duct air conditioner system is installed in the ceiling or wall, responsible for sucking in indoor air and heating or cooling it through the internal heat exchanger, and then sending the processed air back to the corresponding area through the pipe.

[0003] Among them, the pipeline is connected to the indoor unit according to actual needs, and the air outlet is set in the corresponding area of ​​the pipeline to output the air processed by the air-conditioning system. For example, for some small projects, the space in the factory is large and the cost of heat pump central air-conditioning is high, so duct machine will be selected as temperature control equipment, and an indoor unit will be installed in the workshop. In addition, pipelines covering the workshop area will be installed in the workshop, and air outlets will be set at corresponding positions on the pipeline to achieve full coverage of the workshop area by the air-conditioning system.

[0004] Among them, compared with scenes such as office buildings, schools, and family homes, a single space area in a small factory is relatively large, and the wind pressure obtained by the fan drive of the indoor unit itself is relatively small. In particular, the more air outlets are set on a single pipe, the smaller the wind speed at the air outlet is, which leads to insufficient air outlet and a longer cooling or heating effect. If only the fan power of the indoor unit itself is enhanced, it is easy to cause the fan system to overload. Therefore, in order to improve the use effect of the duct air-conditioning system, corresponding fan drive devices can be set at each air outlet on the duct pipeline to accelerate the air outlet at the air outlet, improve the temperature control efficiency and effect, and cooperate with the air guide mechanism to adjust the air outlet direction according to needs (for example, by adjusting the up and down inclination of the guide plate, the air is blown upward when cold air is discharged, and the air is blown downward when hot air is discharged).

[0005] However, in some areas, the humidity is high all year round, and the air outlet temperature of the air conditioning system itself is opposite to the indoor ambient temperature. For example, when the duct air conditioning system discharges cold air, especially the temperature at the pipe mouth and the guide plate at the air outlet is relatively low, the high-humidity and high-temperature air outside is easily exposed to the low-temperature air here, which is easy to form water mist, and the water droplets are easy to gather on the inner wall of the pipe mouth and the surface of the guide plate to form water droplets (especially some air outlets are often closed and opened. When they are closed, due to the influence of the low-temperature air during the previous air outlet, the temperature of the outer wall of the guide plate and the inner wall of the outlet pipe is changed, and it is easier to form water droplets on the outside. When the air outlet is opened for the second time, the water droplets are easily carried away by the airflow). Since the above-mentioned air outlet has a fan drive device, its air outlet is stronger than that of an ordinary duct air conditioning system. Therefore, the strong air flow can easily blow the water droplets away and fall on employees, processing equipment or products, bringing certain impacts. In severe cases, it may even cause failure or damage of processing equipment in the workshop, resulting in property losses. Summary of the invention

[0018] A dual-fan air guide driving method for a duct fan comprises the following steps:

This can prevent the water droplets from being carried away by the strong airflow and blown onto the production equipment or products to cause an impact. At the same time, the water droplets on the inner wall of the air outlet pipe will also be absorbed when they are carried outward by the airflow and pass through the first water absorption structure. This avoids the phenomenon that the strong outlet airflow blows the water droplets away, thereby improving the safety of the equipment. In addition, two sets of fan components can be arranged in each air outlet pipe of the present invention, which can enhance the outlet airflow, increase the airflow coverage, increase the air adjustment area, and improve the practicability of the equipment.

DETAILED DESCRIPTION

[0039] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Refer to the instruction manual Figures 1 to 12 A dual-fan air guide driving device for a duct fan comprises an air duct pipe 1, an air outlet pipe 3, a fan assembly 4 and an air guide assembly 5. The air duct pipe 1 is connected to the output end of an air conditioning assembly 2 (i.e., an indoor unit of the duct air conditioner). The air duct pipe 1 is provided with a plurality of groups of air outlets 11, wherein the air outlets 11 can be provided on one side or on both sides at the same position, depending on the specific usage scenario. The air outlet pipe 3 is fixedly installed in the air outlet 11, the fan assembly 4 and the air guide assembly 5 are provided in the air outlet pipe 3, and the air guide assembly 5 is provided at the output port of the air outlet pipe 3, and the fan assembly 4 is provided in the port of the air outlet pipe 3 corresponding to the inner cavity of the air duct pipe 1.

[0041] The wind guide assembly 5 includes a plurality of wind guide plates 51, which are rotatably mounted in the air outlet pipe 3 via a rotating shaft 52. The rotating axis of the wind guide plates 51 is arranged horizontally. The wind guide assembly 5 also includes a direction adjustment drive assembly for driving the wind guide plates 51 to rotate to adjust the output wind direction. In order to simultaneously rotate and drive the plurality of wind guide plates 51, refer to the attached manual. Figure 4, each rotating shaft 52 is fixedly connected with a swing rod 521, and each swing rod 521 is commonly connected to a connecting rod 522, and the swing rod 521 is rotatably connected to the connecting rod 522, and each swing rod 521 is arranged in parallel with each other, so that a group of parallelogram structures are formed between two adjacent swing rods 521 and the connecting rod 522 and the frame structure of the air outlet duct 3, and then only by driving a group of rotating shafts 52 to rotate, the rotation drive of all air guide plates 51 can be realized, and one group of rotating shafts 52 can be driven to rotate by a motor, or other connecting rod structures can be used to cooperate with a driving device such as a motor or a cylinder to drive and rotate, so as to realize the up and down adjustment of the air outlet direction of the air outlet 11 to fully meet the use requirements.

[0042] Refer to the instruction manual Figure 3 In order to prevent the water droplets formed by the water mist inside the air outlet duct 3 or on the surface of the air guide plate 51 due to the temperature difference in a high humidity environment from being blown out, in this embodiment, a first water absorption structure 6 is provided at the output port of the air outlet duct 3 (i.e., the air outlet port), and a second water absorption structure 7 is provided at the tail end of the air guide plate 51 along the air outlet conveying direction (i.e., the end away from the inner cavity of the air duct pipe 1 after each air guide plate 51 is flipped open).

[0043] In the above embodiment, the first water absorption structure 6 and the second water absorption structure 7 can be solid structures such as sponges, cotton cloth, paper, etc., or they can be used in combination with filters and other granular water absorption materials. The first water absorption structure 6 can be embedded in the inner wall of the output port of the air outlet pipe 3, and the second water absorption structure 7 can also be embedded in the air guide plate 51. However, it should be noted that the exposed parts of the first water absorption structure 6 and the second water absorption structure 7 need to be relatively smooth, and the shape needs to adapt to the shape of the inner wall of the air outlet pipe 3 and the surface of the air guide plate 51 to reduce the impact of airflow on them.

[0044] The above scheme can simply absorb water for air-conditioning equipment that produces less water droplets. For example, the air-conditioning system and the air outlet 11 need to be used for a long time without stopping or closing. Therefore, only a small amount of water droplets will be generated when the air-conditioning system is turned on or just used. The above scheme can be used. However, for scenes that need to be turned on repeatedly or other scenes that produce more water droplets, it is difficult to meet the needs by simply mounting the smaller first water absorption structure 6 and the second water absorption structure 7. Therefore, this embodiment makes the first improvement to the air guide plate 51, referring to the attached manual. Figures 5 to 7The air guide plate 51 includes an outer shell 511 and an inner guide plate 512. The inner guide plate 512 is fixedly connected to the rotating shaft 52, that is, the inner guide plate 512 is directly connected to the air outlet pipe 3. The inner guide plate 512 is slidably matched with the inner cavity of the outer shell 511. The second water absorption structure 7 is filled and installed in the inner cavity of the outer shell 511, and the second water absorption structure 7 is arranged near the tail end of the outer shell 511. The second water absorption structure 7 is preferably a sponge structure. Water permeable channels 513 are arranged on both sides of the outer shell 511 near the tail end. The water permeable channels 513 are used to allow water droplets to enter and contact with the second water absorption structure 7, and then be absorbed by the second water absorption structure 7.

[0045] In the above scheme, the water permeable channel 513 can adopt a simple window structure, that is, a window that penetrates the inner cavity of the outer shell 511 is opened on the surface of the outer shell 511, and the second water absorption structure 7 can extend into the water permeable channel 513, and its shape is adapted to the surface structure of the outer shell 511 to form a smooth plane structure. When water droplets are generated on the surface of the outer shell 511, the water droplets are blown by the air flow, and the water droplets adhere to the surface of the outer shell 511 due to the tension. When they flow to the water permeable channel 513, they come into contact with the second water absorption structure 7 and are absorbed by the second water absorption structure 7, which can prevent the water droplets from being carried away by the strong airflow and blown onto the production equipment or products to cause impact. Since the outer shell 511 is hollow, the internal space is relatively large, and the volume of the second water absorption structure 7 is also relatively large, so it can absorb more water and improve the treatment effect.

[0046] Among them, the two sides of the second water absorption structure 7 can be fixedly connected to the inner guide plate 512 and the outer shell 511 respectively. When a sponge is selected as the second water absorption structure 7, the sponge itself has a certain elasticity and buffering effect. In addition, the outer shell 511 can slide relative to the inner guide plate 512, thereby reducing the impact vibration of the outlet airflow on the air guide plate 51 during actual use, reducing damage and reducing vibration noise.

[0047] It should be noted that in order to improve the buffering effect, an elastic lining 514 can be further provided between the outer shell 511 and the inner guide plate 512. The elastic lining 514 surrounds the inner guide plate 512 and is a rubber structure, thereby enabling buffering in more directions between the outer shell 511 and the inner guide plate 512 to adapt to the strong airflow formed after the fan assembly 4 is added to the present invention.

[0048] Furthermore, during continuous use, the water content of the second water absorbing structure 7 gradually increases, which is not conducive to long-term use. Figure 5 and Figure 7The air outlet 3 is also provided with a lifting driving structure 8, which is used to lift the outer shell 511 upward when the air guide plate 51 swings downward to a vertical state to close the air outlet 3, so that the outer shell 511 and the inner guide plate 512 can squeeze the second water absorption structure 7, squeeze out the water in the second water absorption structure 7, and make it flow downward, so as to facilitate the next use of the second water absorption structure 7, and the lifting driving structure 8 can adopt a drive structure such as a cylinder, and when the air guide plate 51 is turned down to a vertical state, each outer shell 511 is first lifted upward, and also A simple structure can be used. For example, the lifting drive structure 8 is a pad structure 81, which is fixedly installed at the bottom of the air outlet duct 3. An inclined transition portion is provided on the pad structure 81 at a position corresponding to the outer shell 511. As the air guide plate 51 swings downward, the outer shell 511 gradually contacts the top of the pad structure 81, thereby realizing the lifting of the outer shell 511, and each group of air guide plates 51 moves synchronously. Therefore, the outer shell 511 at the bottom will also form a lifting force on the upper outer shells 511, thereby realizing the squeezing of all the second water absorption structures 7.

[0049] It should be noted that in order to reduce the impact on the air flow, please refer to the attached manual. Fig.11 The pad structure 81 is composed of a plurality of flat structures, and the flat structures are arranged parallel to the air outlet direction.

[0050] In the above embodiment, the water permeable channel 513 is a simple through-hole structure, the structure of the second water absorption structure 7 shall not protrude from the water permeable channel 513, and the sponge surface has many micropores and the material is relatively soft. When the airflow directly flows through the protruding plate 518, it will cause a certain disturbance to the second water absorption structure 7, which will affect the airflow to produce noise, and the water on the surface of the second water absorption structure 7 will be easily vibrated out and taken away. For this reason, the present embodiment also makes a second improvement to the air guide plate 51. For details, refer to the attached manual. Figures 8 to 9The tail end of the outer shell 511 is open, and a tail shell 515 is installed at the tail end of the outer shell 511. A protruding plate 518 is arranged on the tail shell 515 corresponding to the surface of the outer shell 511. A reserved spacing is arranged between the protruding plate 518 and the outer shell 511, and the reserved spacing forms a water-permeable channel 513. The two ends of the second water-absorbing structure 7 along the air flow direction are respectively fixedly connected to the inner guide plate 512 and the tail shell 515, and the remaining parts are in a non-connected state, which does not affect the subsequent extrusion of the second water-absorbing structure 7. A water-permeable cloth 516 is connected between the protruding plate 518 and the surface of the outer shell 511. Since the protruding plate 518 is inclined relative to the outer shell 511, the water-permeable cloth 516 is in an inclined state. Therefore, the protruding plate 518 and the water-permeable cloth 516 are formed near the tail end of the outer shell 511. The outer shell 511 is formed into a micro-convex structure, which also includes a gap. In actual use, water droplets on the outer surface of the outer shell 511 will be carried by the airflow to move backward. When moving to the vicinity of the tail end of the wind guide plate 51, the water droplets can penetrate into the protruding plate 518 through the water-permeable cloth 516, and contact the second water-absorbing structure 7 to be received by the second water-absorbing structure 7. The water-permeable cloth 516 is in an inclined state. Therefore, when the airflow passes through this place, it has a tendency to blow the water droplets laterally to the inside of the water-permeable cloth 516, so that the water absorption effect is better, the water droplets will not accidentally fall off, and the water-permeable cloth 516 is used to transition between the outer shell 511 and the protruding plate 518. The overall fluid line will not be too abrupt, and the impact on the airflow is small. At the same time, the airflow will not directly flow through the second water-absorbing structure 7, and will not cause mutual influence, thereby enhancing the use effect.

[0051] Furthermore, in the above-mentioned embodiment, the water absorbed by the second water absorption structure 7 is mainly discharged through the water permeable channel 513 when squeezed, and needs to flow through the outer surface of the outer shell 511 when discharged. If the wind guide plate 51 is closed and not used for a long time, the water on the surface of the wind guide plate 51 will gradually evaporate, but if it is used again immediately, it may be blown out before being absorbed by the second water absorption structure 7. For this reason, the present embodiment also provides the following technical solutions. Specifically, the tail shell 515 is slidably matched with the outer shell 511, and when the tail shell 515 is away from the outer shell 511, there is a space between the tail shell 515 body and the outer shell 511, and the space between the protruding plate 518 and the outer shell 511 is connected, that is, the water permeable channel 513 is connected, and the second water absorption structure 7 can be used normally. When the tail shell 515 approaches the outer shell 511 and completely contacts the outer shell 511, the water permeable channel 513 is blocked. A drain port 517 is provided at the end of the tail shell 515 at a position corresponding to the inner wall of the air outlet pipe 3 (i.e., corresponding to the connection between the rotating shaft 52 and the air outlet pipe 3), and a drainage interface 33 is provided on the side wall of the air outlet pipe 3 at a position corresponding to the drain port 517. Combined with the scheme of the above-mentioned lifting drive structure 8, when the air outlet pipe 3 is temporarily closed and the air guide plate 51 is flipped and swung downward, the tail shell 515 contacts the pad structure 81 and is pushed upward. The tail shell 515 first approaches the outer shell 511 so that it blocks the water permeable channel 513. At the same time, the drain port 517 is docked with the drainage interface 33. When the outer shell 511 is further pushed up, the second water absorption structure 7 is squeezed, and the water in the second water absorption structure 7 will not flow out from the outer side wall of the original outer shell 511, but will be squeezed out from the drain ports 517 at both ends and then flow out through the drainage interface 33, thereby avoiding water residue on the surface of the air guide plate 51.

[0052] It should be noted that in the above scheme, since the sponge itself has a certain elasticity, when the wind guide plate 51 swings upward and the tail shell 515 is separated from the pad structure 81, the tail shell 515 can automatically pop outward to open the water permeable channel 513, and during use, since the protruding plate 518 is relatively protruding, it will be pushed backward when the airflow passes through. Therefore, the stronger the airflow, the greater the force with which the protruding plate 518 and the tail shell 515 are blown backwards. After the displacement occurs, the water permeable channel 513 can also be enlarged. At this time, the tail shell 515 will also form a certain pull on the second water absorption structure 7, making the sponge more fluffy and further enhancing the water absorption effect. That is, the greater the wind force, the greater the water absorption effect will be, further improving the protective effect.

[0053] In addition, in order to adapt to the position change of the protruding plate 518, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Fig. 9One end of the water-permeable cloth 516 is fixedly connected to the surface of the outer shell 511, and the other end of the water-permeable cloth 516 is fitted on the outer surface of the tail shell 515 and slidably cooperates with the tail shell 515. An elastic connecting piece 519 is fixedly connected to the tail shell 515, and the elastic connecting piece 519 is fixedly connected to the water-permeable cloth 516. Then, under the elastic connection of the elastic connecting piece 519, the water-permeable cloth 516 can be pulled, and then when the position of the tail shell 515 changes, the water-permeable cloth 516 can still be kept in a taut and smooth state.

[0054] The above scheme mainly introduces the treatment of water droplets formed on the surface of the air guide plate 51. The treatment of water droplets on the inner wall of the air outlet pipe 3 can be improved by combining appropriate technical solutions, for example, referring to the attached manual. Figure 3 and Figure 5 In order to improve the water absorption effect of the first water absorption structure 6, an inner convex portion 31 is provided on the inner wall of the air outlet port of the air outlet pipe 3, and the inner convex portion 31 protrudes from the inner wall of the flow channel of the air outlet pipe 3. An inclined transition section is provided between the inner convex portion 31 and the inner wall of the air outlet pipe 3, and the first water absorption structure 6 is provided at the inclined transition section. The first water absorption structure 6 can use a sponge structure like the second water absorption structure 7.

[0055] In order to facilitate the treatment of the first water absorbing structure 6 absorbing water, refer to the attached manual. Fig.10 , an extrusion plate 32 is slidably arranged outside the air outlet port of the air outlet pipe 3, and the first water absorption structure 6 is arranged between the extrusion plate 32 and the air outlet pipe 3. Then, in actual use, the extrusion plate 32 can be squeezed manually or by setting a driving device regularly. Although the first water absorption structure 6 is arranged in a quadrilateral shape surrounding the inner wall of the air outlet pipe 3, a drain port can be directly arranged on the air outlet pipe 3. When the first water absorption structure 6 is squeezed, the water inside it is discharged through the drain port. Since the tiny water droplets at the top wall of the air outlet pipe 3 are in a vertical rotation state and are almost difficult to adhere to, the water droplets at the top are The first water absorbing structure 6 absorbs less water, and since the positions of the first water absorbing structures 6 on all sides are basically the same, when the first water absorbing structure 6 is squeezed, even if water is squeezed out of the first water absorbing structure 6 at the top, the water will fall down to the first water absorbing structure 6 below and be absorbed again, and will not fall on the wind guide plate 51 to form residue. Moreover, referring to the structure of the protruding plate 518 and the tail shell 515, a corresponding blocking structure can be set on the extrusion plate 32. When the extrusion plate 32 is squeezed, the exposed surface of the first water absorbing structure 6 is blocked to prevent water from seeping out in the opposite direction.

[0056] Furthermore, the pad structure 81 is slidably installed in the air outlet duct 3, and a cable structure is provided on the pad structure 81, which is fixedly connected to the extrusion plate 32. When the air outlet duct 3 is closed and the air guide plate 51 flips and swings downward, a certain reverse shifting will be generated on the pad structure 81, thereby pulling the extrusion plate 32 to produce automatic extrusion.

[0057] In the above embodiment, the fan assembly 4 includes a motor 41 and fan blades 42. The motor 41 is fixedly installed in the air outlet pipe 3, and the fan blades 42 are fixedly installed on the output end of the motor 41. In order to enhance the air outlet area of ​​the air outlet pipe 3, two groups of fan assemblies 4 can be arranged in each air outlet pipe 3, thereby increasing the air outlet range and air outlet effect. At the same time, since the fan blades 42 will bring a certain rotational inertia when rotating, thereby causing irregular impact on the air outlet pipe 3, for this reason, the blade designs of the two groups of fan blades 42 are opposite, and the rotation directions of the two groups of fan blades 42 are opposite, thereby balancing the rotational inertia and making the equipment more stable.

[0058] Through the above-mentioned settings, in actual use, through the action of the fan components 4 and the air guide components 5 at each position, the air outlet effect of the air outlet 11 can be increased, the airflow can be enhanced, the airflow coverage range can be increased, the air adjustment area can be increased, and the practicality of the equipment can be improved. At the same time, the air guide component 5 can freely adjust the up and down directions of the airflow to enhance the practicality and adaptability of the equipment.

[0059] In actual use, the air outlet duct 3 can be distributed on one side or on both sides at the same position, so as to cover a wider area. However, for the air outlet duct 3 distributed on both sides at the same position, since the output wind force of the fan assembly 4 is relatively large, although the air conditioning assembly 2 itself has a corresponding fan device that can transport the airflow in the air duct pipe 1, the efficient operation of the fan assembly 4 is likely to affect the air outlet volume of the air outlet duct 3 at the rear position, and is likely to form air turbulence in the air duct pipe 1. For this reason, the present embodiment also provides the following technical solutions, refer to the attached manual Fig.12 Two groups of air outlet pipes 3 are arranged in the same area of ​​the air duct pipe 1, and the two groups of air outlet pipes 3 are symmetrically arranged. Two groups of diverter plates 12 are arranged between the two groups of air outlet pipes 3. The diverter plates 12 are fixedly installed in the air duct pipe 1, and then the airflow transported in the air duct pipe 1 is diverted by means of the diverter plates 12, so as to ensure that under the air outlet conditions of the air outlet pipes 3 at the corresponding positions, there can also be sufficient airflow transported backwards, and an inclined guide plate 13 is arranged on one side of the diverter plate 12 corresponding to the air outlet pipe 3, and the inclined guide plate 13 is arranged gradually close to the inclined guide plate 13 along the air flow direction in the air duct pipe 1, so as to improve the transfer effect of the airflow to the air outlet pipe 3.

[0060] Furthermore, in the above-mentioned embodiment, if a group of air outlet pipes 3 needs to suddenly increase the air outlet speed, and the increase is relatively large, at the moment when the fan assembly 4 increases its strength, the air near it is difficult to be supplied in time, forming an instantaneous pressure difference, which is likely to cause a reverse effect on the air duct 1, such as causing direct pressure vibration, and the instantaneous pressure difference will also affect the air flow transportation in the air duct 1, causing air flow turbulence, further increasing the vibration impact on the air duct 1, and forming noise. For this reason, refer to the attached manual Fig.12The inclined guide plate 13 is rotatably connected to the diverter plate 12, and an elastic hollow bag 14 is fixedly connected between the inclined guide plate 13 and the diverter plate 12. A connecting pipe 15 is arranged on the elastic hollow bag 14, and one end of the connecting pipe 15 is connected to the inner cavity of the elastic hollow bag 14, and the other end is connected to the external atmosphere. The elastic hollow bag 14 is a rubber structure, and the elastic hollow bag 14 has the elasticity to support the inclined guide plate 13 to maintain the initial position. When the strength of the fan assembly 4 is suddenly increased, if the air pressure in the air duct pipeline 1 is instantly reduced, the elastic hollow bag 14 is in a normal pressure state. Therefore, when the external air pressure is reduced, it can produce a certain expansion, thereby compensating for the above-mentioned air pressure change, reducing the influence of the air pressure change on the air duct pipeline 1, and further improving the stability and safety of the equipment.

[0061] Refer to the instruction manual Fig.13 The present invention also provides a dual-fan air guide driving method for a duct fan, comprising the following steps:

[0062] Step 1: Turn on the air conditioning assembly 2 to deliver the temperature-adjusted airflow into the air duct 1;

[0063] Step 2: According to the desired air outlet position, drive the air guide plate 51 in the air outlet pipe 3 at that position to flip to a horizontal state;

[0064] Step 3: Turn on the two sets of fan assemblies 4 in the air outlet duct 3 at the position, and the blades 42 of the two sets of fan assemblies 4 rotate in opposite directions;

[0065] Step 4: After the air outlet of the air outlet pipe 3 is stable, adjust the rotation angle of the air guide plate 51 according to the use requirements to adjust it to the required air outlet angle state;

[0066] Step 5: After use, first turn off the fan assembly 4, and after the fan blades 42 completely stop rotating, drive the air guide plates 51 to gradually swing downward, so that the air guide plates 51 are connected in sequence up and down, and the air outlet duct 3 is closed.

[0067] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
