[0037] Reference Figures 1 to 3 This utility model provides a household appliance heating tube with automatic water level monitoring, including: heating component 1, automatic water level monitor 2, temperature control component 4, NTC component 6, high temperature resistant ceramic plug 7, and leak-proof pipe joint component;

[0038] The heating assembly 1 includes a sleeve 101, a tube 102 disposed inside the sleeve 101, a heating wire 103 wound around the tube 102, and a lead rod 7 penetrating the tube 101; the heating assembly 1 is responsible for generating heat to heat the water in the washing machine; the heating wire 103 is made of a metal or alloy wire, which generates heat when an electric current passes through it, and is used to heat the water.

[0039] The NTC component 6, temperature control component 4, automatic water level monitor 2, and leak-proof pipe joint component are all placed on the sleeve 101;

[0040] The high-temperature resistant ceramic plugs 7 are installed at both ends of the sleeve 101 to protect the heating wire 103 and prevent water or impurities from entering the sleeve 101, thereby extending the service life of the heating tube and ensuring safety.

[0041] The corresponding ends of the temperature control component 4 are electrically connected to the NTC component 6 and the heating wire 103, respectively, and are used to adjust the working state of the heating wire 103 according to the water temperature monitored by the NTC component 6, so as to maintain the preset water temperature and ensure the safety and efficiency of the heating process.

[0042] Furthermore, the heating element of the household appliance is installed inside a household washing machine, which can provide hot water during the washing process, which helps to improve washing efficiency, especially when cleaning stubborn stains or in areas with limited cold water supply.

[0043] Furthermore, the leak-proof pipe connector assembly includes a leak-proof pipe connector 3 and a leak-proof pipe connector 5 to ensure a seal at the connection with the washing machine and prevent water leakage; the automatic water level monitor 2 and the leak-proof pipe connector 3 are located at one end of the sleeve 101, and the NTC component 6 and the leak-proof pipe connector 5 are located at the other end of the sleeve 101; the temperature control component 4 is installed in the middle of the sleeve 101; one end of the automatic water level monitor 2 passes through the sleeve 101 and is installed on one end of the guide rod 7; one end of the NTC component 6 passes through the sleeve 101 and is installed on the other end of the guide rod 7.

[0044] Furthermore, the automatic water level monitor 2 is connected to the water inlet valve of the washing machine and automatically adjusts the opening and closing of the water inlet valve according to water level changes to maintain a suitable water level. Based on the monitored water level changes, the automatic water level monitor 2 automatically adjusts the opening and closing of the water inlet valve. When the water level is lower than a preset level, the water inlet valve opens, allowing water to enter the washing machine; when the water level reaches the required level, the water inlet valve closes to prevent overfilling.

[0045] The automatic water level monitor 2 includes a water level sensor for real-time monitoring of the water level inside the washing machine, and the NTC component 6 includes an NTC thermistor for monitoring water temperature. The NTC component 6 utilizes the characteristics of a negative temperature coefficient thermistor to monitor changes in water temperature within the heating element; when the water temperature rises or falls, the resistance value of the NTC thermistor changes accordingly, thus providing real-time data on temperature changes.

[0046] Furthermore, the temperature control assembly 4 includes several thermostats 401 arranged side by side, and a temperature control bracket 402 fitted onto the lower half of the sleeve 101. The thermostats 401 are placed on top of the sleeve 101 and fixed to the temperature control bracket 402 by bolts 403. This fixation ensures the stability and reliability of the thermostats during the operation of the heating element. The thermostats 401 receive temperature signals from the NTC assembly 6 and adjust the operating state of the heating wire 103 according to a preset temperature range. When the water temperature reaches or exceeds the set value, the thermostat 401 automatically disconnects or reduces heating to prevent overheating. The temperature control bracket 402 provides a stable mounting platform for the thermostats 401, ensuring their fixed position within the heating element and facilitating maintenance and replacement. Lead-out tabs 8 are also installed at both ends of the lead rod 7.

[0047] This invention enables automatic water level monitoring and control: the automatic water level monitor can monitor and adjust the water level in the washing machine in real time to ensure the appropriate water level during the washing process, thus avoiding water waste and the risk of overflow.

[0048] This invention enables precise temperature control: through the coordinated operation of the NTC component and the temperature control component, precise control of the water temperature inside the heating element is achieved, improving washing efficiency while avoiding damage to clothes or energy waste caused by overheating.

[0049] This utility model has a simple structure and is easy to maintain: the heating tube is designed simply, and each component is easy to install and maintain, which reduces production and maintenance costs.

[0050] The use of the high-temperature resistant ceramic plug and leak-proof pipe joint assembly of this utility model enhances the safety of the heating tube, prevents water or impurities from entering the heating tube, and reduces malfunctions and safety hazards.

[0051] This invention can improve the quality of laundry: hot water washing can better activate detergent, remove stains from clothes, and provide a higher quality laundry experience.
