Description

Technical Field

[0001] This utility model belongs to the technical field of toilet cleaning, and relates to a swing flushing and drying structure for a self-cleaning toilet. Background Technology

[0002] As a core component of modern sanitary ware, the cleaning performance of toilets directly impacts users' health and safety. Traditional toilets often leave stains, bacteria, and watermarks on the seat surface after use, requiring frequent manual wiping and disinfection—a cumbersome process that also poses a risk of cross-infection. While self-cleaning toilets have emerged in recent years, their technological solutions still have significant shortcomings:

[0003] Insufficient cleaning coverage: Most products use a fixed spray structure, with the nozzles stationary or only able to swing at a small angle. This results in water and air flow not being able to fully cover the curved surface of the seat, leaving many cleaning dead spots and affecting the sterilization effect.

[0004] Low functional integration: The flushing and drying modules usually operate independently, requiring separate operations and extending the cleaning cycle; moreover, the nozzle layout is scattered, taking up a lot of space and making it difficult to adapt to compact toilet designs.

[0005] Low drive efficiency: Existing drive mechanisms mostly rely on single-dimensional rotation, making it difficult to achieve complete coverage of the seat surface. At the same time, the mechanical structure is complex, the failure rate is high, and the maintenance cost is large. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the background art by proposing a swing-flush and blow-dry structure for a self-cleaning toilet.

[0007] To achieve the technical objective, the technical solution adopted by this utility model is as follows:

[0008] The self-cleaning toilet uses a swing-flush and dry structure, including a cleaning chamber located behind the toilet body. The toilet body has an openable toilet seat that can rotate into the cleaning chamber. The cleaning chamber contains a drive unit and a flushing and drying unit. The flushing and drying unit includes at least one flushing pipe and a drying pipe. The flushing pipe is connected to an external pressurized water source, and the drying pipe is connected to a fan. The outlets of both the flushing pipe and the drying pipe face the toilet seat located in the cleaning chamber. The drive unit is connected to the flushing and drying unit and can drive the flushing pipe and the drying pipe to rotate, so that the outlets of the flushing pipe and the drying pipe can cover the entire surface of the toilet seat located in the cleaning chamber.

[0009] To optimize the aforementioned technical solution, the specific measures also include:

[0010] The aforementioned cleaning chamber includes a chamber frame and a chamber panel. The chamber frame is made of rigid material and forms the sides of the cleaning chamber. The chamber panel is fixed to the chamber frame and forms the surfaces of the cleaning chamber.

[0011] The aforementioned drive unit includes a front-to-back rotation drive motor, a mounting base, and a left-to-right rotation drive motor. The front-to-back rotation drive motor is fixedly mounted on the housing frame, and its output shaft is connected to the mounting base. The front-to-back rotation drive motor can drive the mounting base to rotate back and forth. The left-to-right rotation drive motor is fixedly mounted on the mounting base, and its output shaft is connected to the air drying duct. The left-to-right rotation drive motor can drive the air drying duct to rotate left and right.

[0012] The number of flushing pipes mentioned above is several, and they are installed on the mounting base at equal intervals in the left and right directions. The water flow from the flushing pipes can cover the left and right width of the toilet seat in the left and right directions.

[0013] The aforementioned cleaning chamber is equipped with a positioning frame. The upper end of the positioning frame is fixed to the chamber frame. The left end of the mounting base is connected to the front and rear rotation drive motor, and the right end of the mounting base is hinged to the lower end of the positioning frame.

[0014] The number of flushing tubes mentioned above is three.

[0015] The toilet body is equipped with a seat ring motor at the rear. The seat ring motor is connected to the toilet seat ring and can drive the toilet seat ring to open and close.

[0016] The self-cleaning toilet described above uses a swing flushing and drying structure, and also includes a controller. A control valve is installed on the flushing pipe. The control valve can control the opening and closing of the flushing pipe. The controller is connected to the control valve, the fan, the front-to-back rotation drive motor and the left-to-right rotation drive motor respectively, and controls the opening and closing of the control valve, the start and stop of the fan, and the rotation of the front-to-back rotation drive motor and the left-to-right rotation drive motor.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a drive unit to drive the flushing pipe and the drying pipe to perform multi-degree-of-freedom composite motion, thereby achieving three-dimensional dynamic coverage of the toilet seat surface by spray water and hot air. It achieves a large flushing and drying area with a small flushing and drying unit structure, eliminates blind spots in cleaning, and enables the toilet seat surface to be cleaned without dead angles.

[0019] 2. This utility model integrates rinsing and drying functions into a single module. Through the controller, the rinsing valve is opened and closed, the fan is started and stopped, and the movement of the two motors is coordinated to realize the full automation of the "rinsing-drying" process, which is fast and highly automated.

[0020] 3. This utility model features dual motors that independently control forward / backward and left / right rotation. Combined with the hinged support of the positioning frame and the mounting base, it significantly improves motion accuracy, avoids deviation caused by mechanical vibration, and enhances the precision and stability of the drive structure.
