Description

Technical Field

[0001] This utility model relates to the technical field of heating devices, and in particular to a tankless, rapid-heating, anti-dry-burning heating device. Background Technology

[0002] A water heater is a device that supplies electricity to a heating element, causing it to heat up and raise the temperature of cold water to hot water within a certain time. Existing water heaters have the following problems: (1) Existing water heaters rely solely on a temperature sensor to detect temperature and control the heating element. If this temperature sensor fails, the heating element will continue to heat, causing dry burning and potentially leading to a safety accident. Therefore, existing water heaters have low safety. (2) The outer shell of existing water heaters is made of metal, resulting in rapid heat dissipation and poor heat insulation. Therefore, the structure of existing water heaters needs further improvement. Utility Model Content

[0003] The purpose of this invention is to provide a tankless, rapid-heating, anti-dry-burning heating device with high safety and good heat preservation performance.

[0004] The purpose of this utility model is achieved as follows: A tankless, rapid-heating, anti-dry-burning heating device includes a heating element, an inner shell, an outer layer, an anti-dry-burning device, and insulation paper. The inner shell is equipped with a water inlet, a water outlet, a water level sensor, and a temperature sensor. The heating element extends into the inner shell from one end. The outer layer is wrapped around the outer wall of the inner shell. The anti-dry-burning device is located on the outer wall of the inner shell. The water inlet, water outlet, water level sensor, temperature sensor, and anti-dry-burning device are exposed outside the outer layer. The outer layer is made of foam. Insulation paper covers the outer wall of the outer layer. The anti-dry-burning device includes a base, a thermostat, a first terminal block group, and a second terminal block group. The thermostat, the first terminal block group, and the second terminal block group are located on the base, which is located on the inner shell. The probe of the thermostat extends into the inner shell. The thermostat is connected to the first terminal block group and the second terminal block group respectively. The first terminal block group and the second terminal block group are electrically connected to the mains power and the heating element respectively. This invention provides dual protection with its temperature sensor and anti-dry-burning device. Even if the temperature sensor fails, the anti-dry-burning device disconnects the power supply to the heating element, effectively preventing continuous heating and potential dry-burning. Furthermore, the outer layer of this invention is a foamed layer, which offers excellent thermal insulation and heat preservation.

[0005] The present invention can be further improved in the following ways.
