[0019] In this embodiment 1,

[0020] like Figures 1 to 3 As shown, the utility model provides a heater for household appliances, including a shell 1 and an electric heating tube 2 arranged in the shell 1, characterized in that: at least one thermostat 3 and / or thermal fuse assembly 4 is provided at any position on the shell 1; the electric heating tube 2 is provided with a contact end 7; the contact end 7 is in contact connection with the shell 1; the thermostat 3 or the thermal fuse assembly 4 is arranged on the outer surface of the shell 1 adjacent to the contact end 7.

[0021] By arranging at least one thermostat 3 and / or thermal fuse assembly 4 at any position on the housing 1, accurate monitoring of the heater temperature can be achieved, and the power supply can be cut off in time under abnormal circumstances to ensure safe use.

[0022] The electric heating tube 2 is provided with abutting ends 7 which are in abutting connection with the shell 1, thereby enhancing the heat transfer efficiency and making the heating more rapid and uniform.

[0023] The temperature controller 3 is arranged on the outer surface of the shell 1 adjacent to the abutting end 7 to facilitate real-time monitoring of the temperature of the electric heating tube 2.

[0024] The thermal fuse assembly 4 includes a thermal fuse 5 and a pressure plate fixing member 6 ; the thermal fuse 5 is disposed on the housing 1 via the pressure plate fixing member 6 .

[0025] The thermal fuse assembly 4 includes a thermal fuse 5 and a pressure plate fixing member 6. Through this structure, the thermal fuse 5 can be firmly fixed on the housing 1, ensuring that the power supply is reliably cut off when melting is required, thereby improving safety.

[0026] The shell 1 is provided with a water outlet pipe 9 and a water inlet pipe 10 which are in communication with the shell 1 ; the electric heating pipe 2 passes through the shell 1 and extends outwards to be provided with a connecting end 8 .

[0027] A water outlet pipe 9 and a water inlet pipe 10 are provided on the shell 1 and communicated with the inside of the shell 1 , thereby realizing the circulation of the fluid and ensuring a continuous heating effect.

[0028] The electric heating tube 2 extends outward through the housing 1 to provide a connection end 8, which is convenient for connection with an external power source or other components, thereby improving the scalability and compatibility of the device.

[0029] A wire 11 is provided at either end of the thermal fuse 5 and the thermostat 3 . The other ends of the thermostat 5 and the thermal fuse 3 are respectively connected to a power source. The thermal fuse 5 and the thermostat 3 are respectively electrically connected to the connection end through the wire 11 .

[0030] The other ends of the thermostat 5 and the thermal fuse 3 are respectively connected to the power supply, which can provide power to the heater and quickly cut off the power supply, ensuring the heating effect and reliability of the heater;

[0031] The thermal fuse 5 and the temperature controller 3 are electrically connected to the connection terminal 8 through the wire 11, respectively, so that the temperature of the heater can be accurately monitored, thereby improving stability and reliability.

[0032] The inner diameter of the water inlet pipe 10 is larger than the inner diameter of the water outlet pipe 9 .

[0033] The inner diameter of the water inlet pipe 10 is larger than that of the water outlet pipe 9, so that the water inlet flow rate is greater than the water outlet flow rate, which prolongs the residence time of the fluid in the shell 1, thereby being able to absorb heat more fully and improving the heating efficiency and effect.

[0034] like Figures 1 to 3 As shown, in actual use, the thermostat 3 monitors the temperature in real time. When the temperature reaches the set value, the thermostat 3 is activated to cut off the power supply. If the thermostat 3 fails, the temperature of the electric heating tube 2 will continue to rise, causing the thermal fuse 5 to melt, also cutting off the power supply and providing safety protection. By providing the thermostat 3 and thermal fuse assembly 4 on the heater, dual over-temperature protection is achieved. The large inner diameter design of the water inlet pipe 10 enables rapid introduction of water flow, and the relatively small inner diameter of the water outlet pipe 9 ensures that the water flow has sufficient residence time in the housing 1 to be fully heated.

[0035] In this embodiment 2,

[0036] like Figures 1 to 3 As shown, the temperature controller 3 is arranged on the outer surface of the shell 1 adjacent to the abutment end 7, which is convenient for real-time monitoring of the temperature of the electric heating tube 2. In conjunction with the thermal fuse assembly, it can realize accurate monitoring of the heater temperature and timely cut off the power supply under abnormal circumstances to ensure safe use.

[0037] In this embodiment, the power supply is a conventional component in this field and is not marked in the drawings or described in the specification.

[0038] In the description of this specification, reference is made to the terms "one embodiment", "some embodiments", "examples", "specific examples", etc.

[0039] Descriptions such as "example" or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in an appropriate manner. In addition, those skilled in the art can combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without contradiction.

[0040] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as bolts, rivets, welding, and bonding in the existing technology, which will not be described in detail here.
