Description

Technical Field

[0001] This utility model relates to an automatic shower machine, and specifically to a shower machine air circuit system, belonging to the technical field of shower machines. Background Technology

[0002] An automatic shower machine typically consists of a main unit and a trolley for entering and exiting the main unit. The user lies on the trolley to enter and exit the main unit. The upper part of the main unit is a rectangular, enclosed cavity containing the shower chamber (upper shell), while the lower part (inside the lower shell) houses the necessary electromechanical equipment. Rectangular windows with curtains are located on both sides of the shower chamber. Lighting and disinfection systems are installed on the ceiling of the shower chamber. The lower part of the shower chamber contains a water tank, and shower heads are located both above and below the shower chamber. To ensure proper temperature control and timely removal of steam during showering, typical shower machines also include a heating system and an exhaust system (i.e., a gas system). Currently, the mainstream installation method for the heating system in shower machines is to mount the main unit on the top of the machine. The purpose of this design is primarily for waterproofing. This method requires a significant amount of space, increasing the overall height of the shower unit. Since the upper components of the shower unit are all built into the top, and the bathroom ceiling is streamlined, maintenance and disassembly are inconvenient in this case. For the ventilation system, a typical approach is to use an exhaust fan installed on the side wall of the bathroom. While simple, this method is problematic due to the small size of the bathroom, resulting in significant noise and a poor user experience. Direct exhaust from the fan also disrupts airflow within the bathroom, causing excessively rapid air movement in certain areas, leading to lower perceived temperatures and discomfort for the user. Furthermore, the installation of the exhaust fan compromises the overall integrity of the upper part of the bathroom. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in the existing air circuit system of a shower machine and to provide a shower machine air circuit system.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a shower machine air circuit system, the shower machine including an upper shell and a lower shell, windows on both sides of the upper shell, curtains on the windows, a water tank fixedly installed in the lower part of the upper shell, a heating system and an exhaust system installed in the lower shell, the heating system including a heating protective cover fixedly connected to the air inlet side of the heater, a PTC heater fixedly installed in the heating protective cover, the PTC heater having a temperature sensor connected to a heating controller, the heating protective cover having an air inlet hole, the exhaust pipe of the heater being connected to the upper part of the upper shell through the heating pipe, the exhaust direction of the heating pipe being front and back; the exhaust system including an exhaust pipe located in the upper shell, the exhaust pipe being connected to an air inlet box, two fans installed on the air inlet box, an exhaust box installed at the air outlet of the two fans, the two fans on the exhaust box being separated by a partition, two exhaust pipes connected to the exhaust box, the two exhaust pipes corresponding to the two fans respectively.

[0005] Furthermore, an electric control valve is installed on the air outlet pipe of the heater, and the electric control valve is connected to the controller.

[0006] Furthermore, the inlet of the exhaust pipe faces downwards.

[0007] The positive and beneficial technical effects of this utility model are as follows: the main unit of this gas circuit system is installed in the lower shell, which avoids the problems of large height and poor overall integrity caused by installing it on the upper shell. The heater can be waterproofed through the electric valve, and the exhaust fan draws gas from the bathroom through the air inlet box. The airflow is less disturbed during the extraction, resulting in a better user experience. Attached Figure Description

[0013] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0014] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: upper shell; 2: lower shell; 3: window; 4: exhaust system; 5: heating system; 6: exhaust pipe; 7: heating pipe; 8: heating protective cover; 9: air inlet; 10: PTC heater; 11: temperature sensor; 12: heater; 13: electric control valve; 14: heating air outlet pipe; 15: exhaust pipe; 16: air inlet box; 17: fan A; 18: exhaust pipe A; 19: fan B; 20: exhaust pipe B; 21: exhaust box; 22: partition; 23: water tank.

[0015] As shown in the attached diagram; a shower machine air circuit system, the shower machine includes an upper shell 1 and a lower shell 2, with windows 3 on both sides of the upper shell, and curtains installed in the windows. A water tank 23 is fixedly installed in the lower part of the upper shell. A heating system 5 and an exhaust system 4 are installed in the lower shell 2. The heating system includes a heating protective cover 8 fixedly connected to the air inlet side of the heater, and a PTC heater 10 fixedly installed inside the heating protective cover. The PTC heater has a temperature sensor 11 (temperature protection switch). The temperature protection switch can effectively prevent the PTC heater from continuing to work and causing damage in the event of fan failure. The temperature sensor is connected to the heater. The heat controller has an air inlet 9 on its heating protective cover. The air outlet 14 of the heater is connected to the upper part of the upper shell through the air outlet 7. Warm air is blown out through the air outlet 7 in a front-to-back direction. An electric control valve 13 is installed on the air outlet 13 of the heater. As an optimization, a temperature sensor can be installed on the air outlet 13 to detect the temperature of the air outlet. By detecting the temperature value, the PTC heating power and the fan speed can be adjusted. If the temperature is low, the PTC heating power is high and the fan speed is high. The electric control valve is connected to the controller. Closing the electric control valve can prevent water from flowing into the heater and causing damage. The exhaust system includes an exhaust pipe 6 located inside the upper casing. The inlet of the exhaust pipe faces downward to prevent water from entering. The exhaust pipe 6 is connected to an air inlet box 16, on which two fans are installed. The two fans in the figure are fan A17 and fan B19. An exhaust box 21 is installed at the outlet of the two fans. The two ends of the fans are connected to the air inlet box and the exhaust box, respectively. The two fans on the exhaust box are separated by a partition 22 to prevent the airflow of the two fans from interfering with each other. Two exhaust pipes are connected to the exhaust box. The two exhaust pipes are exhaust pipe A18 and exhaust pipe B20, respectively. The two exhaust pipes correspond to the two fans. The two sets of fans work simultaneously to provide greater suction power. Even if one set of fans fails, it will not affect the normal use of the equipment.

[0016] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
