[0002] Yuba is generally installed in the bathroom and integrates functions such as blowing, ventilation, and heating. Yuba is equipped with a fan for air supply and an electric heating component for heating. For a single-fan Yuba, the air path needs to be switched through an air path switching structure to achieve ventilation and heating functions. Existing Yuba switches through air guide plates, which are mostly simple metal straight plate structures. The structure is relatively thin and cannot guarantee structural strength and stability. Under the wind pressure of the fan, it is easy to vibrate and deform, thereby generating noise. There is no corresponding sealing rib position for cooperation, and air is prone to leakage during the switching process, and the air flow direction cannot be accurately controlled.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-10 The utility model provides a technical solution: an air path switching structure, comprising:

[0041] The air guide plate 1 is a plate-shaped workpiece with an angle in the middle; the connecting shaft 104 is welded to the end of the air guide plate 1; the power output end of the power unit 2 is fixedly connected to the connecting shaft 104, which is used to drive the connecting shaft 104 to rotate, and the No. 2 sealing rib structure 5 is placed under the air guide plate 1 and fixedly connected to the shell, which is used to seal the bottom of the air guide plate 1; the end of the No. 1 sealing rib structure 4 is fixedly connected to the end of the No. 2 sealing rib structure 5 and extends outward from the center of the connecting shaft 104, and an acute angle structure is formed between the No. 1 sealing rib structure 4 and the No. 2 sealing rib structure 5.

[0042] It should be noted that the utility model No. 1 plate 101 is installed on one side of the exhaust outlet, and one end of the air guide plate 1 rotates in place as the center of the circle, and the other end swings around the center of the circle with the length as the radius. When ventilation is required, one end of the air guide plate 1 is sealed with the end of the heater, so that the air outlet of the fan is connected with the exhaust outlet. Under the action of the fan, the wind enters from the middle of the fan and passes through the blowing port and is discharged from the exhaust outlet. When heating is required, the power unit 2 drives the air guide plate 1 to rotate to one side of the exhaust outlet, so that the air guide plate 1 blocks the exhaust outlet, so that the air outlet of the fan is connected with the air inlet of the heater, and the wind is blown to the heater for heating and then discharged.

[0043] like Figure 3 , 7 As shown in 8, it also includes a No. 3 sealing rib position structure 8, which is located on the outside of the connecting shaft 104. The horizontal cross-section of the No. 3 sealing rib position structure 8 is an arc structure. The center of the arc of the No. 3 sealing rib position structure 8 is concentric with the connecting shaft 104, and the two ends of the rib are respectively connected to the ventilation opening and the heater opening combination.

[0044] It should be noted that the No. 3 sealing rib structure 8 of the utility model is an arc-shaped structure, and its two connecting ends are respectively extended to connect with the ventilation opening and one end of the heater, thereby increasing the sealing of the overall air duct, preventing wind from passing through the connection when the connecting shaft 104 rotates to reduce the wind pressure, and making the overall connection of the air duct tighter.

[0045] like Figure 1 , 3 As shown in Figures 9 and 10, the wind guide plate 1 is placed at the position of the air outlet, and the wind guide plate 1 includes a No. 1 plate 101 and a No. 2 plate 102. The No. 2 plate 102 is placed at the end of the No. 1 plate 101. There is an obtuse angle structure between the No. 1 plate 101 and the No. 2 plate 102. The No. 2 plate 102 is an arc structure. The arc-shaped effect is set to reduce the impact of wind at the windward position and maintain the consistency of the ventilation channel area and the smoothness of the air duct.

[0046] It should be noted that the obtuse angle structure between the first plate 101 and the second plate 102 of the utility model allows the wind guide plate to adjust the wind direction more accurately; by rotating the wind guide plate 1, the wind direction can be accurately controlled to make the air flow more in line with the needs; one end of the second plate 102 with an arc design can help to achieve uniform distribution of wind force; in the heating state, the flat surface at the front end of the wind guide plate 1 is more inclined, that is, the angle with the wind path is larger, so that the wind pressure on the wind guide plate 1 is greater (the larger the angle, the greater the wind pressure, the maximum at 90° is 0. ), which fits better with the ventilation outlet to reduce air leakage; and allows the wind at the front to change direction in advance, so that the wind on the windward side of the rear heater is more uniform; this is beneficial to improving the air volume performance during heating and reducing noise; in the ventilation state, the angle setting of the air guide plate 1 makes the wind path concave, making the entrance of the wind path smoother and reducing wind resistance noise, and the ventilation area of ​​the middle channel of the wind path is equivalent to that of the entrance (if it is a straight plate, the area of ​​the middle channel is about 5% smaller than that of the entrance), making the ventilation smoother, increasing the air volume and reducing noise.

[0047] like Figure 1 , 2 As shown in FIGS. 4 , 5 and 9 , the power unit 2 includes a mounting frame 21 , a driving motor 22 is fixedly connected to the top of the mounting frame 21 , and an output end of the driving motor 22 is fixedly connected to the connecting shaft 104 .

[0048] It should be noted that the output end of the driving motor 22 of the utility model is fixedly connected to the connecting shaft 104, and the position of the air guide plate 1 can be adjusted by the forward and reverse rotation of the power unit 2, so as to realize the switching of the entire air path.

[0049] like Figure 3 As shown, one end of the No. 1 sealing rib structure 4 away from the connecting shaft 104 and one end of the No. 2 sealing rib structure 5 away from the connecting shaft 104 are connected with an arc guide rail 3 .

[0050] It should be noted that the arc guide rail 3 of the utility model fits the rotation path of the air guide plate 1, which can enhance the movement accuracy of the air guide plate and ensure that it can follow the designed path when rotating, making the air flow direction adjustment more accurate.

[0051] like Figure 1 , 2 As shown in Figures 4, 5, 6, 7 and 9, a first vertical rib 6 is vertically provided at the end of the No. 1 sealing rib structure 4 close to the arc guide rail 3, and a second vertical rib 7 is vertically provided at the end of the No. 2 sealing rib structure 5 close to the arc guide rail 3.

[0052] It should be noted that the first vertical rib position 6 and the second vertical rib position 7 of the utility model are both the switching end points of the air guide plate, and effective sealing is provided at the end points to prevent air leakage during the switching process, better guide the wind flow and reduce air leakage.

[0053] like Figure 3 As shown, the reinforcement structure is a guide rib 103, which is a rectangular strip fitted with the outer side of the air guide plate 1, and both ends of the guide rib 103 are inclined structures.

[0054] It should be noted that the main function of the guide rib 103 of the utility model is to guide the air flow direction. The end inclined structure allows the air to form a certain streamline around the air guide plate 1, thereby more accurately controlling and guiding the air; the guide rib 103 can increase the structural strength and stability of the air guide plate; by adding guide ribs 103 on the side, the air guide plate can be made more stable, thereby reducing vibration and deformation, and improving its stability during operation. Reducing vibration can reduce the noise that may be generated when air flows through the air guide plate, and by optimizing the air flow path, the speed at which turbulence is generated can be slowed down.
