Description

Technical Field

[0001] The present invention relates to the technical field of bathroom heaters, in particular to a bathroom heater with an automatic constant temperature function. Background Art

[0002] Bathroom heaters are designed for humid environments and are designed to increase bathroom temperature by heating air or radiating heat while taking into account moisture resistance, safety and convenience.

[0003] After searching, the patent number is CN219063572U and its name is a dual-outlet bathroom heater. The air duct is connected to the outside through a ventilation port and two blowing ports. The two blowing ports are arranged at the long sides of the bathroom heater box and are not coaxial. The ventilation port is arranged on the side of the bathroom heater box, and a heating module is installed in the blowing port area. The air duct is "S"-shaped as a whole. The left and right ventilation ducts formed around the two wind wheels are connected to the ventilation port in a "Y" shape. The left and right blowing ducts formed around the two wind wheels are connected to a blowing port respectively. Compared with the prior art, the utility model lengthens the length of the air blowing port and the heating module, thereby improving the air blowing and heating effects of the bathroom heater. The "S" shape ensures that the left and right air ducts can blow air and / or heat and ventilate at the same time without interfering with each other, and the "Y" shape can ensure that there is only one ventilation port, which does not affect the installation form of the existing bathroom heater ventilation pipeline. Through research and analysis, it is found that although the air blowing and heating effects of the bathroom heater are improved, the following disadvantages still exist to a certain extent.

[0004] For example, the bathroom heater cannot be automatically adjusted to maintain a constant temperature, causing it to be in operation all the time, resulting in the temperature in the bathroom constantly rising. Excessively high temperatures can easily cause discomfort to users. To solve the above technical problems, we have designed a bathroom heater with an automatic constant temperature function. Summary of the Invention

[0022] See also Figure 1-Figure 5, a bathroom heater with automatic constant temperature function, including a shell 20, one end of the shell 20 is connected to a connecting ring plate 15, the inner wall of the shell 20 is connected to a partition 17, and a blowing fan 16 and an exhaust fan 19 are respectively installed on both sides of the partition 17, and the blowing fan 16 and the exhaust fan 19 can be supported by the partition 17, and the installation of the blowing fan 16 and the exhaust fan 19 is convenient; a cover plate 18 is connected to the center of the top of the partition 17 by bolts, and a connecting ring plate 2 is inserted into the end of the inner wall of the shell 20 near the connecting ring plate 15. Through the cooperation of the connecting ring plate 15 and the connecting ring plate 21, the installation of the bathroom heater is convenient, one end of the connecting ring plate 21 passes through the connecting ring plate 15 and is connected to the packaging panel 1. After the packaging panel 1 is connected to the shell 20, the surfaces of the connecting ring plate 21 and the opposite ends of the connecting ring plate 15 are in contact; Air blowing windows 14 and air intake windows 3 are respectively provided on both sides. The air blowing windows 14 facilitate the blowing out of hot air, and the air intake windows 3 can be used to suck away the dirty air in the bathroom when the exhaust fan 19 is turned on; the end of the packaging panel 1 close to the connecting ring plate 2 11 is connected to a blowing frame 26 used in conjunction with the air blowing window 14, and the inner wall of the blowing frame 26 is connected to a PTC ceramic heater 25. The end of the packaging panel 1 away from the connecting ring plate 2 11 is inlaid with a display screen 2 and a status light 12 respectively. Various types of operating data can be displayed through the display screen 2, and the operating status of the bathroom heater can be displayed using the status light 12; a temperature sensor 21 is installed at the end of the packaging panel 1 close to the connecting ring plate 2 11, and the center of the bottom of the shell 20 is respectively connected to the transmission line 1 9 and the transmission line 2 8, and the side of the transmission line 1 9 away from the shell 20 is connected to the control panel 10. The PTC ceramic heater 25 generates stable heat through electric current and has adaptive temperature regulation characteristics. When the temperature is too high, the resistance increases to reduce the current and avoid the risk of overheating; the temperature sensor 21 is used to monitor the bathroom environment temperature in real time.

[0023] The two sides of the bottom of the shell 20 are respectively connected to an air inlet pipe 22 used in conjunction with the blowing fan 16 and an air outlet pipe 23 used in conjunction with the exhaust fan 19. The inner walls of the air inlet pipe 22 and the air outlet pipe 23 are connected with a grid plate 24; through the air inlet pipe 22, when the blowing fan 16 is turned on, the outside air is introduced into the shell 20; through the air outlet pipe 23, when the exhaust fan 19 is turned on, the dirty air in the bathroom can be discharged; through the grid plate 24, large foreign objects with an outer diameter can be easily introduced into the air inlet pipe 22 and the air outlet pipe 23.

[0024] The inner wall of the air blowing window 14 is connected with a second grid plate 13, and the number of the status lights 12 is several; the air blown out of the air blowing window 14 can be separated by the second grid plate 13, thereby improving the comfort of blowing.

[0025] The inner wall of the air intake window 3 is connected to several positioning blocks 6, and the inner wall of the positioning blocks 6 is connected to the LED light board 4; the LED light board 4 can be supported and positioned by the positioning blocks 6; the output end of the micro-control center 28 is electrically connected to the input end of the LED light board 4.

[0026] The side of the transmission line 2 8 away from the housing 20 is connected to a test plug 7, and the packaging panel 1 is provided with several detection holes used in conjunction with the temperature sensor 21; the test plug 7 is a temporary interface used by manufacturers to quickly test the basic functions of the equipment, such as verifying whether the operation of the PTC ceramic heater 25, the blowing fan 16 and the exhaust fan 19 and the circuit connection are normal. By plugging into an ordinary socket, the core functions of the heater such as heating and ventilation can be powered on and tested without complicated wiring operations. The material and structure of the test plug 7 do not meet the safety standards of the bathroom (such as the lack of waterproofing and leakage protection mechanisms), and are only suitable for short-term testing scenarios.

[0027] The output end of the control panel 10 is electrically connected to the signal processor 27 and the micro-control center 28, respectively. The output end of the micro-control center 28 is electrically connected to the power regulator 29 and the timer 5, respectively. The output end of the micro-control center 28 is electrically connected to the input end of the temperature sensor 21, the status light 12, the display screen 2, the exhaust fan 19, the PTC ceramic heater 25 and the blowing fan 16; the signal processor 27 converts the analog signal of the temperature sensor 21 into a digital signal for processing by the micro-control center 28.

[0028] The output end of the temperature sensor 21 is electrically connected to the input end of the signal processor 27, the output end of the signal processor 27 is electrically connected to the input end of the micro-control center 28, and the output end of the power regulator 29 is electrically connected to the input ends of the exhaust fan 19, the PTC ceramic heater 25 and the blowing fan 16 respectively.

[0029] The output end of the PTC ceramic heater 25 is electrically connected to the input end of the timer 5 , and the output end of the timer 5 is electrically connected to the input end of the blowing fan 16 .

[0030] During use, commands are sent via the control panel 10, and the micro-control center 28 turns on the status light 12, LED light board 4, and display screen 2 according to the corresponding command information. To ventilate the bathroom, a command to turn on the exhaust fan 19 is sent via the control panel 10, and the micro-control center 28 controls the exhaust fan 19 to turn on. To increase the exhaust speed, a command is sent via the control panel 10, and the micro-control center 28 receives the command and adjusts the operating power of the exhaust fan 19 via the power regulator 29, increasing the operating power of the exhaust fan 19 and thereby increasing the exhaust volume.

[0031] When heating is needed in the bathroom, the control panel 10 sends a command to the fan 16 and the PTC ceramic heater 25 to turn on. The micro-control center 28 first controls the PTC ceramic heater 25 to enter the heating state and the timer 5 to start. When the timer 5 reaches the time, the fan 16 turns on, using air to remove the heat from the surface of the PTC ceramic heater 25, forming hot air. This prevents the fan 16 from turning on directly after the PTC ceramic heater 25 turns on. If the surface temperature of the PTC ceramic heater 25 is low, the air blown out through the air window 14 is low, causing discomfort to the human body. To increase the speed of the hot air flow, after sending a command using the control panel 10, the micro-control center 28 receives the command and uses the power regulator 29 to adjust the operating power of the PTC ceramic heater 25 and the fan 16. The power regulator 29 controls the operating power of the fan 16 and the PTC ceramic heater 25 to increase, thereby increasing the heating speed of the bathroom.

[0032] When the temperature sensor 21 detects that the temperature in the bathroom has reached a set value, it sends a command to the signal processor 27. The signal processor 27 sends a command to the micro-control center 28. The micro-control center 28 controls the PTC ceramic heater 25 to first stop running. Then, when the timer 5 reaches the timer duration, the blowing fan 16 is turned off. During this time, the blowing fan 16 removes the heat from the PTC ceramic heater 25, preventing the PTC ceramic heater 25 from being overheated for a long time, thereby reducing its service life. When the temperature sensor 21 subsequently detects that the temperature in the bathroom is lower than the set value, the blowing fan 16 and the PTC ceramic heater 25 enter the normal operation step.

[0033] In summary, the bathroom heater with automatic constant temperature function solves the problem of failure to perform automatic constant temperature adjustment, which causes the bathroom heater to be in operation all the time and causes the temperature in the bathroom to continue to rise. Excessively high temperatures can easily cause discomfort to users.
