Description

Technical Field

[0001] This utility model belongs to the field of heater technology, and specifically relates to a novel variable wind heater main unit. Background Technology

[0002] Bathroom heaters are heating devices specifically designed for bathroom spaces. Their main function is to provide a fast and even warm environment in the bathroom during cold seasons. They heat the air through electric heating elements and use a fan to deliver the warm air, effectively solving the problem of coldness when showering in winter.

[0003] Currently, Chinese utility model patent CN217357016U discloses a heater main unit, including a shell and a cover plate. The cover plate has a first volute and a second volute located inside the shell. The first volute has a first air inlet on the cover plate and a first air outlet on its side. The cover plate has an exhaust port connected to the first air outlet, and a PTC heating element is installed on the exhaust port. The second volute has a second air inlet on the cover plate and a second air outlet on its side. The shell has a ventilation vent connected to the second air outlet. Both the first and second volutes are integrally formed with the cover plate. The first and second volutes respectively have a fan wheel and a fan for controlling the rotation of the fan wheel. This heater main unit has the characteristics of simple structure, good heat dissipation effect, complete overall function, and strong practicality.

[0004] Traditional heaters typically use a fixed air duct design with limited air delivery distance. Some products increase the air delivery distance by increasing the motor power and fan speed, but this leads to increased energy consumption. To solve the above problems, we provide a new type of variable wind heater main unit. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of variable wind heater main unit to solve the problem mentioned in the background art: traditional heaters usually adopt a fixed air duct design and have a limited air delivery distance. Some products increase the air delivery distance by increasing the motor power and fan speed, but this leads to increased energy consumption.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel variable wind heater main unit, including a housing, a cover plate bolted to the top of the housing, a volute hot air chamber integrally injection molded inside the housing, a first motor bolted inside the volute hot air chamber, a PTC ceramic heater bolted to the air outlet of the volute hot air chamber, and a variable wind mechanism provided on one side of the PTC ceramic heater;

[0007] The variable air mechanism includes an air outlet shell, the bottom of which is bolted to the housing. An integrally molded rectifier plate is installed inside the air outlet shell. Two air guide plates are installed inside the air outlet shell, and rotating rods are integrally molded at both ends of each air guide plate. The surfaces of the rotating rods are rotatably sleeved with the air outlet shell. A connecting rod is integrally molded at one end of each air guide plate. A sliding groove adapted to the connecting rod is provided on the top of the air outlet shell. A third motor is bolted to the front of the air outlet shell. A swing plate is fixedly sleeved at the output end of the third motor. A pin is sleeved at the other end of the swing plate. Two swing arms are rotatably sleeved on the surface of the pin. A slot is provided at one end of each swing arm, and the interior of the slot engages with the connecting rod. The surface of the connecting rod is rotatably connected to the swing arm.

[0008] Preferably, the housing has an integrally injection-molded volute ventilation chamber, and a second motor is bolted inside the volute ventilation chamber.

[0009] Preferably, the output ends of both the first motor and the second motor are fitted with impellers, and the output ends of both the first motor and the second motor are threaded with fixing nuts.

[0010] Preferably, the cover plate has two integrally injection-molded circular grooves that are adapted to the impeller, and the cover plate also has an integrally injection-molded through groove that is adapted to the air outlet shell.

[0011] In summary, this utility model has the following beneficial effects:

[0012] The device generates airflow by driving a fan wheel to rotate using a first motor. This airflow is then heated by a PTC ceramic heater to produce a stable hot air output. Simultaneously, a third motor drives a swing plate and swing arm, which in turn drive a guide plate to rotate in opposite directions. Without changing the power of the first motor, the air pressure at the outlet can be altered simply by adjusting the mechanical structure, allowing the hot air to cover a greater distance. This significantly improves the heating range and comfort. This mechanical air pressure regulation method avoids the increased energy consumption problem associated with traditional variable frequency speed control. It ensures the stability of heat output while reducing energy consumption, effectively solving the problem of short air delivery distance in traditional heaters while maintaining low cost.
