Description

Technical Field

[0001] This invention relates to the field of electrical appliances, and more particularly to a lifting heater structure. Background Technology

[0002] Integrated bathroom heaters are installed in the bathroom during home renovations, integrated with the ceiling. They provide heating and lighting functions, saving space and offering greater safety and convenience. The installation structure of the integrated bathroom heater and the ceiling affects the ease of use.

[0003] For aesthetic and moisture-proof purposes, existing integrated ceiling heaters are generally installed with concealed air outlets. This means the air outlet overlaps with the ceiling surface and is covered and its direction adjusted via flaps. However, this type of ceiling heater has significant limitations on the airflow direction and angle. Therefore, lift-up panel designs have emerged, but these are typically bulky and unsuitable for small ceiling spaces. Thus, a ceiling heater with a liftable panel that occupies less space is urgently needed in the market. Summary of the Invention

[0004] A retractable heater structure includes a housing and a panel, with the opening of the housing sealed by the panel. A first air duct is provided inside the housing, with a first fan at one end and a second fan at the other end. The first fan is connected to the first air duct, and the second air duct is connected to a ventilation port on the side wall of the housing. A second air duct is provided outside the first fan, and a third air duct is provided outside the second fan. The second and third air ducts have the same structure, and both the second and third air ducts include an upper air duct and a lower air duct. The upper air duct is positioned at the front and rear... The wall is provided with guide blocks, and the front and rear walls of the lower air duct are provided with guide grooves corresponding to the guide blocks. When the upper air duct and the lower air duct are fastened together, the guide blocks are embedded in the guide grooves and can slide along the guide grooves. The top of the upper air duct is fixedly connected to the bottom surface of the panel. A lifting structure is provided between the second air duct and the side wall of the box, and between the third air duct and the first air duct. The fixed end of the lifting structure is fixed to the bottom surface of the box, and the moving end of the lifting structure is fixedly connected to the panel. A heating device is provided in the first air duct. An air outlet is opened on the panel corresponding to the first air duct, and a swivel structure is provided in the air outlet.

[0005] Furthermore, the lifting structure includes a guide rail, a guide rail motor, and a guide rail bracket. The guide rail motor is disposed inside the guide rail bracket, and the output end of the guide rail motor is connected to a guide screw. The guide screw is upwardly positioned and connected to the guide rail. A guide sleeve is disposed inside the guide rail, and the guide sleeve is screwed to the guide screw.

[0006] Furthermore, guide rail connecting surfaces are provided between the second air duct and the side wall of the housing, and between the third air duct and the first air duct. Guide rail mounting holes are opened on the guide rail connecting surfaces. After the guide rail passes through the guide rail mounting holes, the guide rail fixing ring is fitted around the outside of the guide rail.

[0007] Furthermore, the panel is fitted with a panel frame, and panel fasteners are provided between the left and right ends of the panel and the panel frame; the fasteners include a magnet and an iron piece that cooperate with each other, the magnet is set in a magnet fixing piece and connected to the top surface of the guide rail, and the iron piece is set in an iron piece connector and fixed to the bottom surface of the panel; the magnet and the iron piece attract each other to connect the panel to the guide rail.

[0008] Furthermore, the page-swinging structure includes a page swing, a page swing frame, and a page swing motor; the page swing frame is disposed inside the air inlet, the page swing is disposed inside the page swing frame, and rotating shafts are provided at the left and right ends of the page swing, the rotating shafts passing through the page swing frame and connected to the page swing motor.

[0009] Furthermore, the heating device includes a heating bracket, a PTC heating block, and a heating cover. The heating bracket is located at the top outlet of the first air duct, the PTC heating block is located inside the heating bracket, and the top of the heating bracket is sealed by the heating cover.

[0010] Furthermore, a limit switch is provided at the bottom of the first air duct, and a limit switch lever is provided on the side wall of the guide rail to cooperate with the limit switch. The limiting distance between the limit switch and the limit switch lever is the lifting stroke of the lifting structure.

[0011] The beneficial effects of this invention are as follows: 1. The panel can move up and down under the action of the lifting structure. After the panel is raised, the fan inside the box starts to operate, and heating or ventilation begins. When no work is needed, the panel can be retracted and hidden.

[0012] 2. As the panel rises and falls, the upper air duct moves up and down accordingly. When it reaches its highest point, the inner cavity of the second air duct expands to its maximum to meet the ventilation space requirements. When the panel is no longer needed, it descends simultaneously, reducing the inner cavity of the second air duct, and the second fan stops working, thus saving space. Attached Figure Description
