Abstract
A toilet air heating device, control method and a toilet including such device/method, which include an air heating fan, an external air duct, an internal air duct, an air heating wire component, a drive mechanism, and a controller. The internal air duct is accommodated inside the external air duct and telescopes, as driven by the drive mechanism, along the extension direction of the external air duct. An air outlet of the air heating fan is sequentially in communication with the air heating wire component, the external air duct, and the internal air duct. An internal air duct outlet of the internal air duct includes an auxiliary heater. The controller is in communication connection with each of the air heating wire component, the air heating fan, the drive mechanism and the auxiliary heater.
Claims20
A toilet air heating device, comprising:
- an air heating fan;
- an external air duct;
- an internal air duct located inside the external air duct and selectively repositionable between an extended position and a retracted position, wherein an internal air duct outlet of the internal air duct includes an auxiliary heater;
- an air heating wire component, wherein an air outlet of the air heating fan is sequentially in communication with the air heating wire component, the external air duct, and the internal air duct;
- a drive mechanism configured to telescopically move the internal air duct relative to the external air duct along an extension direction of the external air duct;
- and
- a controller in communication connection with each of the air heating wire component, the air heating fan, the drive mechanism, and the auxiliary heater and configured to, in response to a start instruction, actuate the auxiliary heater and cause the drive mechanism to move the internal duct into the extended position.
A toilet, comprising:
- a toilet body;
- a seat disposed on the toilet body, wherein the toilet body at the back of the seat includes an accommodating cavity having a through hole;
- and
- a toilet air heating device integrated with at least one of the toilet body and the seat, wherein the toilet air heating device comprises:
- an air heating fan;
- an external air duct;
- an internal air duct located inside the external air duct, wherein an internal air duct outlet of the internal air duct includes an auxiliary heater;
- an air heating wire component, wherein an air outlet of the air heating fan is sequentially in communication with the air heating wire component, the external air duct, and the internal air duct;
- a drive mechanism configured to telescopically move the internal air duct relative to the external air duct along an extension direction of the external air duct;
- and
- a controller in communication connection with each of the air heating wire component, the air heating fan, the drive mechanism, and the auxiliary heater and configured to, in response to a start instruction, actuate the auxiliary heater and cause the drive mechanism to move the internal duct into an extended position;
- and
- wherein the internal air duct outlet of the internal air duct of the toilet air heating device can extend out from the through hole, and wherein the auxiliary heater is coupled to the internal air duct outlet to form an integral piece with the internal air duct outlet.
