Description
Technical Field
[0001] The utility model relates to the field of electrical equipment, in particular to a blowing device. Background Art
[0002] A common bathroom heater (or heating ventilation fan, bathroom heater, etc.) includes a fan, an air duct connected to the fan, an air outlet matched with the outer end of the air duct, and an air guide vane matched with the air outlet. The air guide vane is rotated (rotation is electrically controlled) to adjust the direction of the air guide vane, and the size of the air outlet is controlled by the air guide vane and the air outlet. The air outlet direction is controlled by the air guide vane, and the air outlet direction can only rotate along the rotation direction of the air guide vane. Therefore, there are the following problems: 1. The air outlet direction is only adjusted along the rotation direction of the air guide vane, resulting in a relatively small air outlet angle and range, which is not suitable for use in larger spaces. It can only blow to local areas, and other areas cannot be blown by wind, or it is too diffuse and cannot be gathered to blow to the surrounding distant areas, affecting the overall comfort of use; 2. It is not conducive to controlling the blowing range, especially when you don’t want the wind to blow to people (bathing), or you want the wind to blow to people and the surrounding areas (before or after bathing), it is difficult to meet the requirements. Summary of the invention
[0003] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and to provide a blowing device. At least through a rotating device, the direction of the air outlet of the air guide device is adjusted toward the direction of the first end of the air guide body or the direction of the second end of the air guide body. By facing the directions of different ends respectively, the wind can be focused in one direction to blow farther. The rotation can make the wind blow over a larger range, so that it is suitable for use in a larger space. It is also easy to control the wind direction to be toward a specific area without blowing on people or blowing on people, thereby improving the flexibility and comfort of use.
[0004] The above technical purpose of the utility model is mainly solved by the following technical solutions: a blowing device, comprising an air guide device arranged on a base, the air guide device having an air inlet and an air outlet, characterized in that the air guide device is arranged on the base by a rotating device, and the rotating device is used to adjust the direction of the air outlet of the air guide device toward the direction of the first end of the air guide device or toward the direction of the second end of the air guide device. The air outlet direction of the air guide device is set to face the first end, and the air guide device is driven to rotate along the axis of the length direction by the rotating device. When rotating 180 degrees, the original air inlet is changed to the air outlet, and the original air outlet is changed to the air inlet, so that the air outlet faces the second end, achieving the purpose of adjusting the air outlet direction from the first end to the second end, and can be used in a larger space (such as a bathroom with dry and wet separation, the direction can be adjusted to blow toward the wet area, or the direction can be adjusted to blow toward the dry area, and the adjustment angle is 360 degrees, that is, the blowing direction is changed by 180 degrees). When you don't want the wind to blow on the human body, you can achieve the purpose by controlling the rotating device to adjust the appropriate wind direction (including the lateral angle and the inclination angle toward one end) (for example, when showering in a wet area, adjust the wind guide device to a suitable angle (usually the adjusted angle is between 0 and 180 degrees) through the rotating device, so that the wind only blows on the wet area and not on the human body).
[0005] That is to say, at least the direction of the air outlet of the air guide device is adjusted toward the direction of the first end of the air guide body or the direction of the second end of the air guide body through the rotating device. By facing the directions of different ends respectively, the wind can be focused in one direction to make the wind blow farther. The rotation can make the wind blow over a larger range, so that it is suitable for use in a larger space, and the wind direction can be easily controlled to be directed toward a specific area without blowing on people or blowing on people, thereby improving the flexibility and comfort of use.
[0006] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: in order to facilitate the control of wind direction and to facilitate concentrated blowing, the wind guide device includes a long wind guide body, a plurality of wind guide pieces arranged in the inner cavity of the wind guide body, the wind guide pieces are arranged obliquely toward the first end of the wind guide body, the first end of the wind guide body is adapted to the first end of the wind guide device, and the second end of the wind guide body is adapted to the second end of the wind guide device. The arrangement of the wind guide pieces enables blowing to be directed toward one end of the wind guide device, making it possible to adjust the blowing direction at a large angle.
[0007] From the first end to the second end of the air guide body, the inclination angle of the air guide piece decreases in sequence, and the first end and the second end are arranged opposite to each other. That is, with the center line of the length direction of the air guide device as the center line, the accumulated inclination angle on one side of the air guide device is greater than the accumulated inclination angle on the other side, so that the blowing direction is always toward one end of the air guide device, which is convenient for changing the blowing direction by 180 degrees.
[0008] The rotating device includes a rotating shaft respectively arranged at the first end and the second end of the air guide body, and the air guide body is rotated around the rotating shaft through the rotating shaft. In practical applications, the rotating device also includes a driving motor, and the driving motor only needs to drive the rotating shaft at any end to rotate the air guide body. Of course, the technical solution of setting driving motors at both ends of the rotating shaft is not excluded, and setting driving motors at both ends also falls within the protection scope of the utility model.
[0009] The rotating device drives the rotating shaft to rotate, and the air guide body is rotated through the rotating shaft, which can conveniently change the blowing direction by 180°, and conveniently control the blowing angle and blowing range while keeping blowing in one direction. That is, when blowing toward the wet area (or dry area), while keeping blowing toward the wet area (or dry area), the blowing direction and blowing range are adjusted within the wet area (or dry area), for example, from the direction toward the sprinkler head to the direction away from the sprinkler head, and away from the sprinkler head, but still blowing toward the wet area, and the blowing width range can be adjusted (the width direction is the same as the width direction of the air guide body).
[0010] As a priority, the air guide is fixed to the air guide body so that the air guide moves synchronously with the air guide body, and the rotation range of the air guide body is 0-360 degrees. Compared with the prior art, the air guide structure of this technical solution is simple, easy to assemble, and the assembly is stable and reliable (in the prior art, the air guide is pivotally connected to the air guide body, and the wind direction is adjusted by adjusting the direction of the air guide. The air guide structure is complex, the assembly process is more, and the assembly stability and operation stability are not very good.)
[0011] Preferably, when the air guide body rotates at an angle greater than 180°, the direction of the air outlet changes from a direction toward the first end to a direction toward the second end.
[0012] As a priority, when the rotation range of the air guide body is 0-180°, the air outlet is oriented toward the first end, and the air outlet is adjusted laterally within a certain width range. That is, while keeping blowing toward one end (i.e. one end in the length direction), the air outlet direction and air outlet range can be changed in the width direction.
[0013] As a priority, when the rotation range of the air guide body is 180° to 360°, the air outlet is oriented toward the second end, and the air outlet is adjusted laterally within a certain width range. While the air outlet direction is adjusted from one end to the other end, the air outlet direction and air outlet range can also be changed in the width direction.
[0014] Preferably, an air supply channel is arranged on the base, and the cross-section of the inner cavity of the air supply channel is a trapezoid with a larger inner end and a smaller outer end. The air guide device is arranged in the inner cavity of the air supply channel, the length of the air supply channel is adapted to the length of the air guide device, the outer end width of the air supply channel is adapted to the width of the air guide device, and the rotating shafts arranged at both ends of the air guide device are pivotally connected to the end walls at both ends of the air supply channel.
[0015] As a preference, a heating device is provided at the air inlet of the air guide body to heat the air and blow out warm air. The heating device can be provided above one end of the air guide body, or above the middle area of the air guide body, or above the entire air guide body. No specific requirements are made for the specific location of the heating device. The setting of the heating device is used to enable the blowing device to blow hot air.
[0016] The utility model has the following beneficial effects: 1. At least by adjusting the direction of the air outlet of the air guide device toward the direction of the first end of the air guide body or the direction toward the second end of the air guide body through the rotating device, the direction toward different ends can be used in a larger space, and the blowing can be changed at a large angle of 180° to meet the needs of users in different areas. 2. Under the premise of maintaining the general direction of blowing toward one end unchanged, the blowing angle and blowing range are controlled in the width direction, and the wind direction of the wind is easily controlled without blowing people, thereby improving the flexibility and comfort of use. 3. By changing the blowing angle and blowing range by 180° reversal or maintaining the blowing direction of one end, accurate blowing is achieved, which is conducive to improving energy utilization, that is, by changing the cumulative angle of the air guide plate by tilting the air guide plate or by gradually changing the tilt angle, the air guide plate controls the main direction of the blowing to blow toward one end of the air guide body. At the same time, in conjunction with the lateral rotation of the air guide body, the adjustment of the blowing angle and blowing range is achieved under the premise of keeping the main direction of the blowing unchanged. 4. The air guide piece is fixed in the air guide body, which simplifies the structure, improves assembly efficiency, improves operation stability and reduces maintenance rate.

[0026] The technical solution of the utility model is further specifically described below through embodiments and in combination with the accompanying drawings. The first end and the second end mentioned herein refer to the two ends of the long strip air guide body in the length direction.
[0027] Example 1: Figure 1-Figure 3 As shown, a blowing device includes an air guide device 2 arranged on a base 1, and the air guide device 2 has an air inlet 3 and an air outlet 4. In specific use, a fan is arranged in the base 1, and an air duct connected to the air outlet 4 of the fan, and the air outlet 4 of the air duct cooperates with the air inlet 3 of the air guide device 2. In order to improve the visual effect and quality of the blowing device, a panel 9 is arranged on the base 1.
[0028] The main difference between the present technical solution and the prior art is that the rotating device is at least used to adjust the direction of the air outlet 4 of the air guide device 2 toward the direction of the first end of the air guide body 5 or toward the direction of the second end of the air guide body 5.
[0029] Specifically, the air outlet direction of the air guide device 2 is set toward the first end, and the rotating shaft is driven to rotate by the driving motor on the rotating device, and the air guide device 2 is driven to rotate along the axis in the length direction by the rotating shaft. When rotating 180 degrees, the original air inlet 3 is changed to the air outlet 4, and the original air outlet 4 is changed to the air inlet 3, so that the air outlet 4 is directed toward the second end, so as to achieve the purpose of adjusting the air outlet direction from the first end to the second end. By facing the directions of different ends respectively, the wind can be focused in one direction, so that the wind blows farther, and the wind can be blown in a wider range with the rotation, so that it is suitable for use in a larger space, and it is easy to control the wind outlet direction to be directed to a specific area without blowing on people or blowing on people, thereby improving the flexibility and comfort of use.
[0030] For example, in a bathroom with dry and wet separation, the direction of the air blowing can be adjusted to the wet area, or the direction of the air blowing can be adjusted to the dry area, and the adjustment angle is 360°, that is, the blowing direction can be changed by 180°. When you don't want the wind to blow on the human body, you can achieve the purpose by controlling the rotating device to adjust the appropriate wind direction. For example, when taking a shower in the wet area, the wind guide device 2 can be adjusted to a suitable angle by the rotating device. The angle is usually adjusted between 0 and ±90° or ±90 and 360°, so that the wind only blows on the wet area and does not blow on the human body. Figure 4 As shown, the special-shaped curved surface below the blowing device is a schematic diagram of the air outlet range 11, that is, the area range where the air outlet angle and range can be conditioned.
[0031] In order to facilitate the control of wind direction and to facilitate concentrated blowing, the wind guide device 2 includes a long wind guide body 5, a plurality of wind guide pieces 6 arranged in the inner cavity of the wind guide body 5, and the wind guide pieces 6 are arranged obliquely toward the first end. The wind guide pieces 6 are arranged obliquely toward the first end of the wind guide body, the first end of the wind guide body 5 is adapted to the first end of the wind guide device, and the second end of the wind guide body 5 is adapted to the second end of the wind guide device. The arrangement of the wind guide pieces 6 enables blowing to be done toward one end of the wind guide device 2, making it possible to adjust the blowing direction at a large angle.
[0032] In order to simplify the structure, facilitate assembly, and improve working stability, the air guide plate 6 is fixed on the air guide body 5, so that the air guide plate 6 and the air guide body 5 move synchronously, and the rotation range of the air guide body 5 is 0-360°. Among them, the air guide plate has a zero-point positioning function of 0°, and generally starts at the zero-point positioning position and rotates in one direction, and generally the rotation angle does not exceed 350°.
[0033] Compared with the prior art, the present technical solution has a simple structure of the air guide piece 6, is easy to assemble, and is stable and reliable to assemble (in the prior art, the air guide piece 6 is pivotally connected to the air guide body 5, and the wind direction is adjusted by adjusting the direction of the air guide piece 6. The air guide piece 6 has a complex structure, many assembly steps, and poor assembly stability and operation stability.)
[0034] Specifically, when the air guide body 5 rotates 180°, the direction of the air outlet 4 changes from the direction toward the first end to the direction toward the second end.
[0035] When the rotation range of the air guide body 5 is 0-180°, the air outlet 4 faces the first end, and the air outlet 4 can be adjusted laterally within a certain width range. That is, while blowing air toward one end (i.e., one end in the length direction), the air outlet direction and air outlet range can be changed in the width direction.
[0036] When the rotation range of the air guide body 5 is 180° to 360°, the air outlet 4 faces the second end, and the air outlet 4 can be adjusted laterally within a certain width range. While the air outlet direction is adjusted from one end to the other end, the air outlet direction and air outlet range can also be changed in the width direction.
[0037] The rotating device includes a rotating shaft 7 respectively arranged at the first end and the second end of the air guide body 5, and the air guide body 5 is rotated around the rotating shaft 7 through the rotating shaft 7. In practical applications, the rotating device also includes a driving motor, and the driving motor only needs to drive the rotating shaft at any end to rotate the air guide body. Of course, the technical solution of setting driving motors at both ends of the rotating shaft is not excluded, and setting driving motors at both ends also falls within the protection scope of the utility model.
[0038] The driving motor drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the air guide body 5 to achieve a 180° change in the blowing direction. When blowing in one direction, the rotation amplitude of the rotating shaft is controlled to control the rotation angle of the air guide body 5, so that the blowing angle and blowing range can be controlled while blowing in one direction (such as Figure 8 That is, when blowing toward the wet area (or dry area), while keeping blowing toward the wet area (or dry area), the blowing direction and blowing range are adjusted within the wet area (or dry area), for example, the blowing direction is adjusted from the direction toward the shower head to the direction away from the shower head, and away from the direction of the shower head, but still toward the wet area, and the blowing width range can be adjusted (the width direction is the same as the width direction of the air guide body 5 as the width direction).
[0039] The base 1 is provided with an air supply channel 8 , and the cross section of the inner cavity of the air supply channel 8 is a trapezoid with a larger inner end and a smaller outer end, that is, the air inlet 3 of the air supply channel 8 is larger than the air outlet 4 of the air supply channel 8 .
[0040] The air guiding device 2 is arranged in the inner cavity of the air supply channel 8, the length of the air supply channel 8 is adapted to the length of the air guiding device 2, the outer end width of the air supply channel 8 is adapted to the width of the air guiding device 2, and the rotating shafts 7 arranged at both ends of the air guiding device 2 are pivotally connected to the end walls at both ends of the air supply channel 8.
[0041] In order to enable the blowing device involved in the technical solution to blow both normal temperature wind and warm wind, and to further improve the function of the blowing device, a heating device 10 is arranged at the air inlet 3 of the air guide body 5, which is used to heat the air and blow out warm wind. The heating device 10 can be arranged above one end of the air guide body 5, or above the middle area of the air guide body 5, or above the entire air guide body 5. There is no specific requirement for the specific setting position of the corresponding heating device 10. The setting of the heating device 10 is used to enable the blowing device to blow hot wind.
[0042] Example 2: Figure 4-Figure 7 As shown, the technical solution involved in this embodiment is different from that in Embodiment 1 in that:
[0043] From the first end to the second end of the air guide body 5, the inclination angle of the air guide piece 6 decreases in sequence, and the first end and the second end are arranged opposite to each other. That is, with the center line of the length direction of the air guide device 2 as the center line, the accumulated inclination angle on one side of the air guide device 2 is greater than the accumulated inclination angle on the other side, so that the blowing direction is always toward one end of the air guide device 2, which is convenient for changing the blowing direction by 180 degrees and makes it easier to focus the blowing.
[0044] In this technical solution, the air guide piece 6 can adopt a technical solution of a flat plate structure (such as Figure 4 and Figure 5 ), you can also choose the curved surface structure technology solution (such as Figure 6 and Figure 7 ).
[0045] For Example 1 or Example 2, in actual application, a bathing intelligent control mode is set for the hair dryer, and the heating sequence of the bathroom is controlled by a program. According to the bathing logic, air is supplied (hot air or natural air, and the following description takes hot air supply as an example, and the control mode of natural air supply is the same as that of hot air supply). Before bathing, the hot air is mainly supplied to the human body, and the cold area of the bathroom is blown to concentrate the heat, which can quickly heat up. After bathing, the hot air is mainly supplied to the non-human body direction, which can not only continuously heat the bathroom area, but also avoid the discomfort caused by continuous blowing on the human body, which is conducive to improving the user experience. Its control schemes include at least the following:
[0046] Solution 1: If Fig. 9As shown, the intelligent bathing control mode is turned on, the blower blows hot air, and the rotating device makes the air guide blow towards the undressing area (referred to as area D) in the bathroom space, and at the same time controls the lateral swing angle of the air guide to ±A°, which is used to evenly heat area D, which is conducive to improving the comfort of this area. When the time module in the control system detects that the heating time reaches t1 (this time can be set to a fixed time or temporarily adjusted according to actual conditions), the blowing direction of the blower is adjusted, and the rotating device is rotated 180°. At the same time, the lateral swing angle of the air guide is controlled to ±A°, and the wind direction is toward the bathing area (referred to as area B), and area B is evenly heated; on the contrary, if the time does not reach t1, area A continues to be blown and heated continuously. When the time module in the control system detects that the heating time reaches t2 (this time can be set as a fixed time or temporarily adjusted according to actual conditions), the blowing direction is adjusted horizontally, and the wind guide device is controlled to swing within the horizontal swing angle A° or -A° range (angle A° or -A° is determined according to actual conditions, mainly to avoid area C when the human body is bathing), so that the hot air blows to area B while avoiding area C where the human body is located, avoiding blowing to the wet human body and causing discomfort, which is conducive to maintaining continuous heating of area B and avoiding discomfort to the human body, achieving windless bathing, and thus achieving maximum comfort. On the contrary, if the time does not reach t2, the entire area B will continue to be evenly and continuously heated.
[0047] Solution 2: If Fig.10 As shown, the difference between Scheme 2 and Scheme 1 is that the temperature detection condition is added:
[0048] Turn on the intelligent bathing control mode, the blower blows hot air, the rotating device makes the air guide blow towards the undressing area (referred to as area D) in the bathroom space, and at the same time controls the lateral swing angle of the air guide to ±A°, which is used to evenly heat area D, which is beneficial to improving the comfort of this area. When the time module in the control system detects that the heating time reaches t1 or the temperature reaches T1 (the time and temperature can be set as fixed time, or can be temporarily adjusted according to actual conditions), the blowing direction of the blower is adjusted, and the rotating device is rotated 180°. At the same time, the lateral swing angle of the air guide is controlled to ±A°, and the wind direction is toward the bathing area (referred to as area B), and area B is evenly heated; on the contrary, if the time does not reach t1 or the temperature does not reach T1, area A continues to be blown and heated. When the time module in the control system detects that the heating time reaches t2 or the temperature reaches T2 (the time and temperature can be set as fixed time or temporarily adjusted according to actual conditions), the blowing direction is adjusted horizontally, and the wind guide device is controlled to swing within the horizontal swing angle A° or -A° range (the angle A° or -A° is determined according to actual conditions, mainly to avoid area C when the human body is bathing), so that the hot air blows to area B while avoiding area C where the human body is located, avoiding blowing to the wet human body and causing discomfort, which is conducive to maintaining continuous heating of area B and avoiding discomfort to the human body, achieving windless bathing, and thus achieving maximum comfort. On the contrary, if the time does not reach t2, the entire area B will continue to be evenly and continuously heated.
[0049] Solution 3: If Fig.11 As shown, the difference between Scheme 3 and Scheme 1 is that a human body position detection procedure is added:
[0050] The intelligent bathing control mode is turned on, the blower blows hot air, and the rotating device makes the air guide blow towards the undressing area (referred to as area D) in the bathroom space, and at the same time controls the lateral swing angle of the air guide to ±A°, which is used to evenly heat area D, which is beneficial to improving the comfort of this area. When the time module in the control system detects that the heating time reaches t1 (this time can be set to a fixed time, or it can be temporarily adjusted according to actual conditions) or a human body is detected in the bathing area (referred to as area B), the blowing direction of the blower is adjusted, and the rotating device is rotated 180°. At the same time, the lateral swing angle of the air guide is controlled to ±A°, and the wind direction is toward the bathing area (referred to as area B), and area B is evenly heated; on the contrary, if the time does not reach t1 or the human body is not detected in area B), area A continues to be blown and heated. When the time module in the control system detects that the cumulative time of human body detection in area B reaches t2 (this time can be set as a fixed time or temporarily adjusted according to actual conditions), the blowing direction is adjusted horizontally, and the wind guide device is controlled to swing within the horizontal swing angle A° or -A° range, so that the hot air blows to area B while avoiding area C where the human body is located, avoiding blowing to the wet human body and causing discomfort, which is conducive to maintaining continuous heating of area B and avoiding human discomfort, achieving windless bathing, and thus achieving maximum comfort. On the contrary, if the time does not reach t2, the entire area B will continue to be evenly and continuously blown and heated.
