Description

Technical Field

[0001] The present invention relates to the field of smart home appliances, and in particular to an intelligent temperature-controlled bathroom heater. Background Art

[0002] A bathroom heater is a common device installed in the bathroom. When the heater is turned on, the heater draws in air from the bathroom, heats it, and then blows it back into the bathroom to prevent the indoor temperature from being too low. Application number CN202310358648.5 provides a warm current series of heat ring bathroom heaters that use PTC (a ceramic heating element) as the heating element.

[0003] Specifically, heating is achieved by using a heating element, PTC ceramic or carbon fiber; when the drive motor rotates, the drive motor drives the No. 1 drum to rotate, and when the No. 1 drum rotates, the fan blades inside the No. 1 drum rotate, and when the fan blades rotate, the fan blades agitate the airflow below. When the airflow below flows, cold air enters from the gap between the installation box and the lower panel and flows through the PTC ceramic or carbon fiber heating element, and is blown out as warm air. After the hot air passes through the heating element, the warm air enters the air outlet and contacts the diverter plate. The diverter plate prevents the warm air from blowing out directly from the top, forcing the warm air to blow out from the annular gap between the diverter plate and the cylindrical slot, thereby heating the interior of the bathroom;

[0004] The air inlet is located in the gap between the concealed box and the lower panel. If the indoor air is to enter the columnar groove, the lower panel needs to protrude downward from the indoor ceiling, which is not only unsightly but also poses a potential risk of falling.

[0005] In addition, although the indoor temperature can be quickly raised, the "warm air is blown out from the annular gap between the diverter plate and the cylindrical groove", and the area of ​​the "thermal energy ring" is limited, which easily makes the wind speed blown out high, and the heating area of ​​different parts of the body is different, resulting in uneven body temperature; and the wind blown out over a large area is blown out in a ring shape due to its special air outlet structure, which makes it difficult to achieve the ideal heating effect and user experience; for this reason, the present invention provides an intelligent temperature-controlled bathroom heater.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention has a simple structure. By adding a slow wind device, the wind speed of the warm air blown into the room is reduced, making the human body feel more comfortable. By adding a strengthening device, the wind volume of the warm air blown into the room is increased. The cooperation with the slow wind device reduces the wind speed and makes the body heated more evenly. The rectangular slow wind device can increase the area where the warm air is blown out, achieving the effect of rapid temperature increase. The air inlet and the slow wind device are on the same side, which facilitates the installation of the present invention and ensures the aesthetics of the ceiling.

[0021] Through the connection between the threaded shaft and the threaded hole, the motor can drive the main fan and the secondary fan to rotate, thereby increasing the air volume generated and helping to quickly heat up the room. Due to the elasticity of the spring, the threaded hole has a certain buffering effect when it contacts the threaded shaft. In conjunction with the thrust brought by the electric push rod, a slight abutting force is formed on the threaded hole, so that the threaded connection with the threaded shaft can be made without stopping the motor, ensuring the continuity of the warm air supply.

[0022] The temperature of the warm air is controlled by multiple buffer fans. The buffer fans reduce the wind speed of the warm air and also reduce the temperature of the warm air. The warm air blows on the buffer fans, causing the buffer fans to rotate and blow the warm air into the room, reducing the wind speed, making the warm air blowing towards the human body softer and more comfortable. The temperature control effect is better, the operation is convenient and more intelligent, and the operation can be completed with only a controller. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 3-5 As shown, the strengthening device 5 includes a plurality of transversely arranged gears 51, a chain 52, a pushing structure 53 and a fixed plate 54; the fixed plate 54 is rotatably connected to the rotating rod 43 and the outer wall of the pushing structure 53, and the fixed plate 54 located at the rotating rod 43 extends downward with a protective ring 541, which is sleeved on the outer wall of the rotating rod 43 to make the rotating rod 43 more stable when rotating. The outer circumference of the fixed plate 54 extends toward the inner wall of the mounting groove 11 and is fixedly connected; a plurality of gears 51 are located on the upper side of the fixed plate 54 and correspond to the fan 41. The gear 51 in the middle is fixedly connected to the end of the pushing structure 53 away from the fan 41, and the gears 51 on both sides are fixedly connected to the rotating rod 43; the plurality of gears 51 are transmission-connected to the chain 52, and the rotation of the chain 52 drives the gear 51 to rotate, and the rotation of the gear 51 drives the rotating rod 43 to rotate;

[0038] The pushing structure 53 includes an electric push rod 531, a turntable 532, a plurality of fixed rods 533 and a threaded shaft 534. The electric push rod 531 is rotatably connected to the fixed plate 54. The driving end of the electric push rod 531 is fixedly connected to the turntable 532. One end of the fixed rod 533 is slidably connected to the threaded shaft 534, and the other end is fixedly connected to the turntable 532 facing the side of the motor 42. The plurality of fixed rods 533 are arranged in a ring along the outer circumference of the threaded shaft 534; the outer wall of the threaded shaft 534 close to the turntable 532 has no threads, so that the fixed rod 533 can slide, and the end of the threaded shaft 534 away from the motor 42 is fixedly connected to a limiting disk 5341 for limiting the sliding distance of the fixed rod 533; the limiting disk 5341 is fixedly connected to one end of a spring 61, and the other end of the spring 61 is fixedly connected to the turntable 532. The elastic extension distance of 1 is greater than or equal to the sliding distance of the fixing rod 533; the middle part of the rotating shaft of the motor 42 near the threaded shaft 534 is provided with a threaded hole for matching with the threaded shaft 534, so that after the electric push rod 531 pushes the threaded shaft 534 to move to the threaded hole, when it continues to move, the spring 61 begins to be compressed, so that there is a slight abutment force between the threaded shaft 534 and the threaded hole, and under the rotation of the rotating shaft driven by the motor 42, the threaded shaft 534 begins to be threadedly connected with the threaded hole, thereby driving the pushing structure 53 to rotate, thereby driving the middle gear 51 to rotate, and the middle gear 51 mobilizes the chain 52 to rotate, and finally drives the secondary fan 412 to rotate; the diameter of the end of the threaded shaft 534 facing the threaded hole is slightly smaller than the diameter of the end of the threaded hole, so that the threaded shaft 534 is easy to align with the threaded hole.

[0039] like Figure 3 As shown, the heating device 3 includes multiple heating rings 31 and a pair of heating rods 32, the heating rings 31 correspond to the fan 41; the pair of heating rods 32 penetrate the multiple heating rings 31 to connect the multiple heating rings 32, and the ends of the heating rods 32 extend to the inner wall of the mounting groove 11 and are fixedly connected.

[0040] like Figure 3 and 6 -8, the wind slowing device 2 includes a fixed frame 21 and multiple connecting rods 22 inside the fixed frame 21, multiple rotating rings 23 and multiple buffer fans 24. The fixed frame 21 is a rectangular frame, and the buffer fans 24 are arranged in a rectangular shape inside the fixed frame 21. There is a certain gap between adjacent buffer fans 24. The rotating ring 23 is rotatably connected to the outer wall of the buffer fan 24. The inner wall of the fixed frame 21 and the rotating ring 23 are fixedly connected by the connecting rod 22. The rotating rings 23 adjacent to each other in the horizontal or vertical direction are fixedly connected by the connecting rod 22, so that the air volume blown from the direction of the heating device 3 is adjusted by the buffer fan 24; the end of the buffer fan 24 facing the heating ring 31 is fixedly connected with a wind resistance part 62, and the wind resistance part 62 is conical, and the sharp end faces the heating ring 31, so as to reduce the loss of the blowing air volume.

[0041] Working principle: The threaded shaft 534 is disengaged from the threaded hole, which serves as the initial state. When using the bathroom heater, the operator turns on the switch on the wall or turns on the bathroom heater through the controller. The heating ring 31 and the heating rod 32 start to heat up, and the motor 42 starts to rotate. The motor 42 drives the main fan 411 to rotate, and the indoor wind enters the upper side of the main fan 411 through the air inlet 121 and the flow channel 13. The air volume formed by the main fan 411 blows toward the buffer fan 24. After passing through the heating ring 31 and the heating rod 32, the air volume is heated to form warm air. The air volume continues to move and blows toward the buffer fan 24. A part of the warm air passes between adjacent buffer fans 24. The buffer fan 24 rotates, and as the buffer fan 24 rotates, new buffer warm air is formed and blown into the room; the wind speed of the buffer warm air is lower than the warm air, and then it is mixed with a part of the warm air 1 blown out first in the room, which reduces the wind speed of the warm air 1, thereby making the overall wind speed softer, making it more comfortable to blow towards the human body, and the heating effect more uniform, and will not affect the user experience due to overheating of the warm air. Since the wind resistance portion 62 is conical and the sharp end faces the heating ring 31, unnecessary wind loss can be reduced and the utilization efficiency of the wind volume can be improved.

[0042] When the outdoor temperature is extremely low and more warm air is needed to ensure the indoor temperature, the strengthening device 2 can be started to increase the warm air; the electric push rod 531 is started by the controller, and the driving end of the electric push rod 531 begins to drive the threaded shaft 534 to move toward the direction of the motor 42, so that the end of the threaded shaft 534 contacts the end of the threaded hole; the electric push rod 531 continues to drive the threaded shaft 534 to move, the spring 61 is compressed, and the fixing rod 533 slides from close to the limit plate 5341 to close to the threaded hole, so that the threaded shaft 534 and the threaded hole are slightly abutted, which facilitates the matching of the threaded hole and the threaded shaft 534 for threaded connection; as the motor 42 continues to rotate, the threaded hole and the end of the threaded shaft 534 begin to be threadedly connected, and under the continuous push of the electric push rod 531 on the threaded shaft 534, the threaded shaft 534 is placed in the threaded hole and is completely threadedly connected with the threaded hole; the electric push rod 531 stops pushing, and the electric push rod 53 In the process of driving the threaded shaft 534 to move, it always moves at a low speed to ensure the smooth progress of the threaded connection; then, under the rotation of the motor 42, the threaded shaft 534 is driven to rotate, the threaded shaft 534 drives the fixed rod 533 to rotate, the fixed rod 533 drives the turntable 532 and the electric push rod 531 to rotate, the end of the electric push rod 531 away from the threaded hole drives the gear 51 to rotate, the gear 51 drives the chain 52 to rotate, the chain 52 drives another gear 51 to rotate, thereby driving the rotating rod 43 to rotate, and finally driving the secondary fan 412 to rotate, and together with the main fan 411 to generate more air volume, the remaining flow process is as described above; it should be noted that due to the addition of the additional secondary fan 412, the overall speed of the fan 41 is inevitably reduced, thereby reducing the wind speed of the generated air volume, which has a certain effect on decelerating the warm air blown into the room, thereby ensuring that the indoor warmth rises peacefully. After use, when closing the reinforcing device 5, the motor 42 is turned off through the controller, and then turned on again, and the motor 42 is rotated in the reverse direction, and then the electric push rod 531 is started, so that the driving end of the electric push rod 531 moves toward the fixed rod 54. As the motor 42 rotates in the reverse direction, the threaded shaft 534 gradually moves out of the threaded hole until it disengages, and the spring 61 returns to the uncompressed state. Finally, the electric push rod 531 and the motor 42 are turned off.

[0043] If the indoor temperature is too high or it is stuffy, you can open the air exchange port 121, close the heating ring 31 and the heating rod 32, and turn on the motor 42, so that the outdoor space enters the installation groove 11 and is blown into the room through the buffer fan 24 to regulate the indoor air.

[0044] Example 2

[0045] On the basis of Example 1, Figure 9 and Figure 5As shown, a detection rod 71 is fixedly connected to the middle of the rotating shaft of the motor 42 near the threaded shaft 534. The detection rod 71 is located in the middle of the threaded hole, and a correction hole 55 is opened in the middle of the corresponding threaded shaft 534 to match the detection rod 71.

[0046] The cross-section of the end of the detection rod 71 away from the motor 42 is triangular, so that before the threaded shaft 534 is inserted into the threaded hole, the detection rod 71 is first inserted into the correction hole 55, ensuring that the threaded hole and the threaded shaft 534 maintain the same axial direction when threaded together. Even if the threaded shaft 534 deviates when moving toward the motor 42, the tapered end of the detection rod 71 can still be smoothly threaded into the threaded hole.

[0047] A sensor is installed at the tapered end of the detection rod 71, and the sensor is electrically connected to the alarm; a telescopic rod 56 is rotatably connected to the middle of the correction hole 55, and the length of the telescopic rod 56 is the same as the length of the correction hole 56; when the end of the detection rod 71 enters the correction hole 55, the end of the telescopic rod 56 first contacts the tapered end of the detection rod 71 and triggers the sensor, indicating that it is working normally; when the threaded shaft 534 descends, it deviates, and the end of the telescopic rod 56 does not contact the sensor, but contacts the tapered side of the detection rod 71. The sensor sends a signal to the alarm, indicating that the driving end of the electric push rod 531 has deviated, and the alarm reminds the user that there is a problem with the electric push rod 531 and it needs maintenance.
