[0002] With the improvement of living standards, intelligent sanitary wares have been widely used. At present, the main components of the heater market are composed of a heating element, a ceramic tube, a 47°C temperature switch, a 70°C temperature switch, an inlet water temperature sensor, and an outlet water temperature sensor. The dry-burning protection device mainly relies on the 70°C temperature switch to achieve. When heating is in use, the temperature switch has a thermal fuse, which senses the temperature of the ceramic tube or ceramic chip heating through heat transfer. When the temperature reaches the limit, the thermal fuse disconnects, and the ceramic tube stops heating to play a protective role.

[0003] However, in the prior art, the overall structure of the heater is complex, the assembly efficiency is low, the production cost is increased, and during the process of the temperature of the ceramic tube being transmitted to the thermal fuse, it has to pass through the ceramic tube, the medium heat-conducting copper plate in the heating cavity, and the copper plate conducts heat to the temperature switch. There is a large amount of heat loss in the whole process, and the thermal fuse cannot be reset after disconnection. Summary of the Utility Model

[0025] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a cross-sectional view of a heating device provided by the present application.

[0026] The present application provides a heating device. As Figure 1 shown, the heating device of this embodiment includes: a housing 10, a heating element 20, and a control element (not shown in the figure). Combining Figure 2 with Figure 3As shown, a housing 10 is formed with an accommodation space 101. A heating element 20 is disposed within the accommodation space 101. A heating body 201 and a temperature sensing body 202 are uniformly arranged within the heating element 20. A control member is coupled to the heating body 201 and the temperature sensing body 202. Among them, the accommodation space 101 is formed within the housing 10 and is an integrally formed structure. The heating element 20 is in a flat plate shape and is horizontally and uniformly inserted into the accommodation space 101 along the axial direction of the housing 10. A liquid flow channel is provided between the heating elements 20. When heating the liquid, the liquid can be uniformly heated. The heating element 20 can also be vertically inserted into the accommodation space 101 along the axis direction of the housing 10, and specific limitations are not made in this application. Among them, as the temperature changes, the temperature sensing body 202 generates different temperature sensing signals. When the control member detects the temperature sensing signal generated by the temperature sensing body 202 at a preset temperature, the control member controls the heating body 201 to stop heating. Among them, the temperature sensing body 202 is a temperature sensing wire and can be made of conductive materials such as copper, nickel, and platinum with good electrical conductivity and stable resistance characteristics. When the temperature of the heating body 201 rises, the resistance of the temperature sensing body 202 rises and is synchronously fed back to the control member, so that the control member controls the heating body 201 to stop heating. It can also be a thermistor, and specific limitations are not made in this application.

[0027] In an alternative embodiment, the housing 10 forms the accommodation space 101. The heating element 20 is horizontally and uniformly inserted into the accommodation space 101 along the axial direction of the housing 10. The control member is disposed outside the housing 10 and is respectively connected to the heating body 201 and the temperature sensing body 202 through lines. For example, the heating body 201 is connected through a power line to control the working state of the heating body 201, and the temperature sensing body 202 is connected through a signal line to receive the temperature signal of the heating element 20. After liquid is introduced into the housing 10, the control member controls the heating body 201 to heat. The temperature rise of the heating body 201 causes the heating element 20 to heat the liquid. Specifically, the temperature sensing body 202 generates different temperature sensing signals as the temperature changes. After the liquid in the housing 10 is discharged, in order to prevent the heating device from dry burning, the temperature sensing body 202 can feedback the surface temperature of the heating element 20 to the control member. When the control member detects through the temperature sensing body 202 that the heating element 20 reaches the preset temperature, the control member controls the heating body 201 to stop heating. Similarly, when a fault occurs in the heating device and the heating element 20 continuously heats and dry burns, the control member obtains the temperature sensing signal fed back by the temperature sensing body 202 and thus controls the heating body 201 to stop heating.

[0028] In this embodiment, the temperature sensor 202 is a temperature sensing wire disposed inside the heating element 20. Specifically, a sampling resistor is arranged inside the heating element 20. When the heating element 201 heats up, the resistance value of the sampling resistor changes to monitor the surface temperature of the heating element 20. When heating the liquid inside the housing 10, after the liquid inside the housing 10 is heated to the required temperature and discharged, the sampling resistor feeds back the resistance value to the control element. When there is no liquid in the housing 10 and the heating element 20 continues to heat, since the resistance value change of the temperature sensor 202 can monitor the surface temperature of the heating element 20, and during the heating process, the resistance value of the temperature sensing resistor of the heating element 201 and the heating temperature of the heating element 201 are linearly related. That is, when the heating device is dry burning, the heating element 201 can heat the temperature of the heating element 20 to the preset temperature. When the preset temperature is reached, the resistance value of the temperature sensor 202 will be synchronously fed back to the control element. After receiving the resistance value signal of the temperature sensor 202, the control element controls the heating element 201 to stop heating. That is, by directly monitoring the surface temperature of the heating element 20 through the temperature sensor 202, without the need for other temperature switches, it can effectively reduce the heat loss during the process of the temperature sensor 202 detecting the temperature, and by installing the heating element 20 inside the accommodation space 101 of the housing 10, without the need to install other heating switches, it reduces the assembly process of the heating device and effectively improves the production efficiency.

[0029] In the above embodiment, by forming an accommodation space 101 in the housing 10 and arranging a heating element 20 containing a temperature sensor 202 and a heating element 201 inside the accommodation space 101, the resistance value of the temperature sensor 202 changes with the surface temperature of the heating element 20, so that the temperature sensor 202 monitors the surface temperature of the heating element 20. When the heating element 20 reaches the preset temperature, the resistance value of the temperature sensor 202 will be synchronously fed back to the control element. After receiving the resistance value signal of the temperature sensor 202, the control element controls the heating element 201 to stop heating, effectively preventing the heating device from dry burning and being damaged. And by directly monitoring the surface temperature of the heating element 20 through the temperature sensor 202, without the need to install other temperature switches, it can effectively reduce the heat loss during the process of the temperature sensing wire detecting the temperature, and reduce the assembly process to improve the production efficiency.

[0030] In an alternative embodiment, the heating element 20 further includes a ceramic body 203. The heating element 201 and the temperature sensing element 202 are uniformly arranged in the ceramic body 203, and the heating element 201 and the temperature sensing element 202 are arranged at intervals. Using the ceramic body 203 for heating makes the heating element 201 generate heat more uniformly during heating, with a wide heating range, thereby reducing the energy consumption during heating. Among them, the ceramic body 203 is horizontally and uniformly arranged in the accommodation space 101 along the axial direction of the housing 10. Fixing members (not shown in the figure) can be provided on the opposite end faces of the housing 10. The fixing members are arranged oppositely, and the ceramic body 203 is horizontally clamped on the fixing members. The distance between the fixing members on the side wall of the housing 10 is uniformly set. When the ceramic body 203 is installed on the fixing members, the distance between the ceramic bodies 203 is the same, enabling the ceramic body 203 to uniformly heat the liquid inside the housing 10. Further, the heating element 201 is uniformly arranged inside the ceramic body 203. When liquid is introduced into the housing 10, the heating element 201 can uniformly heat the ceramic body 203, so that the ceramic body 203 uniformly heats the liquid, ensuring the stability of the ceramic body 203 in heating the liquid. Similarly, the temperature sensing element 202 is uniformly arranged inside the ceramic body 203, and the heating element 201 and the temperature sensing element 202 are arranged at intervals. When the temperature sensing element 202 monitors the surface temperature of the heating element 20, it can ensure the accuracy of detecting the surface temperature of the heating element 201.

[0031] In this embodiment, as Figure 5 shown, one end of the housing 10 away from the water inlet pipe 401 is detachably connected with a cover plate 70. A second gasket 701 is arranged between the cover plate 70 and the housing 10, and the second gasket 701 is clamped and fixed by the cover plate 70 and the housing 10. A pressing plate 702 connected to the second gasket 701 is clamped between the cover plates 70. That is, the cover plate 70 is arranged at one end of the housing 10 away from the water inlet pipe 401. After the heating element 20 is inserted into the accommodation space 101, the heating element 20 can be further fixed by the cover plate 70. Setting the cover plate 70 on the housing 10 makes the accommodation space 101 form a closed space to heat the introduced liquid. A second gasket 701 is arranged between the housing 10 and the cover plate 70 to prevent the liquid in the accommodation space 101 from overflowing. And a pressing plate 702 is arranged between the cover plates 70, enabling the pressing plate 702 to fix the second sealing ring 504 to prevent the second sealing ring 504 from falling off. Among them, the pressing plate 702 can be set in an "H" shape to fix the four sides of the second sealing ring 504, or can be set in other shapes adapted to the second sealing ring 504. The present application does not make specific limitations here.

[0032] In an alternative embodiment, as Figure 5As shown in the figure, at least one flow channel partition 30 is arranged in the accommodation space 101, and the heating element 20 and the flow channel partition 30 are arranged in the accommodation space 101 in a stacked manner in sequence. Among them, a clamping member (not shown in the figure) adapted to the flow channel partition 30 is arranged on the side wall of the housing 10, and the flow channel partition 30 can be clamped on the clamping member, so as to fix the flow channel partition 30. The clamping members are evenly arranged on the side wall of the housing 10, which can evenly divide the flow channel of the liquid, so that the heating element 20 can uniformly heat the liquid inside the accommodation space 101. The heating element 20 and the flow channel partition 30 are arranged in the accommodation space 101 in a stacked manner in sequence, that is, the flow channel partition 30 can divide the liquid flowing into the housing 10, making the heating flow channel of the liquid more regular, thereby improving the stability of heating by the heating element 20. Further, both the flow channel partition 30 and the heating element 20 are arranged at intervals from at least one inner wall of the housing 10. That is, the liquid flowing into the accommodation space 101 can flow through the interval flow channel between the flow partition, the heating element 20 and the side wall of the housing 10, so as to ensure the heating of the liquid flowing into the accommodation space 101. Among them, as Figure 4 and Figure 5 shown, there can be 2 heating elements 20 and 3 flow channel partitions 30. The heating elements 20 are arranged between the flow channel partitions 30. The heating elements 20 and the flow channel partitions 30 can also be set to any reasonable number such as 1, 3, 5, etc., and can be specifically set according to needs. The present application does not make specific limitations here. Further, as Figure 6 shown, the heating body 201 and the temperature sensing body 202 are connected to the control member through the interface 80, and can also be connected to the control member through other electrical connection methods. The present application does not make specific limitations here.

[0033] In an optional embodiment, as Figure 5As shown, a water inlet pipe 401 and a drain pipe 402 communicating with the accommodation space 101 are provided at one end of the housing 10. The water inlet pipe 401 is arranged close to the bottom wall of the housing 10, and the drain pipe 402 is arranged on the side wall of the housing 10 away from the water inlet pipe 401. By providing the water inlet pipe 401 and the drain pipe 402 at one end of the housing 10, liquid can be introduced into the accommodation space 101 through the water inlet pipe 401. Since the water inlet pipe 401 is arranged close to the bottom wall of the housing 10, that is, when the liquid is introduced into the accommodation space 101, it is introduced into the accommodation space 101 from the bottom of the housing 10. As the water level rises, the liquid will pass through the flow channel partition 30 and the heating element 20 arranged inside the accommodation space 101, thereby heating the liquid. Due to the presence of the flow channel partition 30, when heating the liquid, the heated liquid rises between the flow channel partitions 30, and then is discharged through the drain pipe 402 arranged on the side wall of the housing 10 away from the water inlet pipe 401. The flow channel partition 30 can evenly heat the liquid, effectively preventing the liquid from flowing irregularly in the accommodation space 101, thereby preventing waste of resources caused by continuously heating the heated liquid. And the heating element 20 and the flow channel partition 30 are arranged in sequence. When the liquid rises through the flow channel partition 30, the heating element 20 can heat the rising liquid, and the heated liquid will not flow repeatedly downward to the bottom, but will directly rise to the outlet of the drain pipe 402 and be discharged after heating.

[0034] In an alternative embodiment, as Figure 5As shown, a first sensor 501 and a second sensor 502 are respectively connected to a water inlet pipe 401 and a drain pipe 402 inside a housing 10. A channel (not shown in the figure) is formed in the housing 10. The first sensor 501 and the second sensor 502 are both arranged in the channel. The first sensor 501 is connected to the water inlet pipe 401, and the second sensor 502 is connected to the drain pipe 402. That is, when liquid is introduced into the accommodation space 101, the first sensor 501 is connected to the water inlet pipe 401 to monitor the temperature of the liquid inside the water inlet pipe 401. After the liquid inside the accommodation space 101 is heated, it is discharged through the drain pipe 402. The second sensor 502 is connected to the drain pipe 402 to monitor the temperature of the liquid inside the drain pipe 402 after heating. Further, gland covers 503 connected to the housing 10 are arranged at one ends of the first sensor 501 and the second sensor 502. Sealing rings 504 are arranged at the ends of the first sensor 501 and the second sensor 502 away from the gland covers 503. The gland covers 503 are arranged at one ends of the first sensor 501 and the second sensor 502 to mount the first sensor 501 and the second sensor 502 on the housing 10. The sealing rings 504 are arranged at the ends of the first sensor 501 and the second sensor 502 away from the gland covers 503 to prevent liquid from entering the first sensor 501 and the second sensor 502 when the liquid flows in the water inlet pipe 401 and the drain pipe 402, so as to damage the first sensor 501 and the second sensor 502.

[0035] In an alternative embodiment, as Figure 5 shown, a grounding plate 60 is arranged at one end of the housing 10 close to the water inlet pipe 401. A first gasket 601 is arranged between the grounding plate 60 and the housing 10. Therefore, the grounding plate 60 is arranged at one end of the housing 10. When the heating device works, since the heating device works in a humid environment, the heating device is grounded through the grounding plate 60, which can prevent electric current from passing through the human body to cause harm when the heating device is damaged by insulation or there is a human operation error, thus ensuring the safety of personnel. At the same time, during the operation of the heating device, grounding can also eliminate the danger of overvoltage, prevent system oscillation, improve the safety of the heating device and the circuit, and thus protect electrical equipment.

[0036] In a specific embodiment, when assembling the heating device, the flow channel partition 30 is snap-fitted onto the snap-fitting member so that the flow channel partition 30 is fixed within the accommodation space 101. The heating element 20 is inserted between the flow channel partitions 30 so that the heating element 20 is fixed within the accommodation space 101. Then, the cover plate 70 with the second gasket 701 is fixed to the end of the housing 10, thereby fixing the heating element 20, and the pressing plate 702 is snap-fitted within the cover plate 70, thereby fixing the second sealing ring 504. Then, the first sensor 501 and the second sensor 502 can be fixed to the housing 10 such that the first sensor 501 communicates with the water inlet pipe 401 and the second sensor 502 communicates with the drain pipe 402. Further, the grounding plate 60 with the first gasket 601 is fixed to one end of the housing 10 away from the cover plate 70 to ensure the safety during the operation of the heating device. Among them, the grounding plate 60 and the cover plate 70 can be fixed to the housing 10 by screws, or can also be fixed by means such as pins or bonding. The present application does not make specific limitations herein.

[0037] By the above method, in the present application, an accommodation space 101 is formed in the housing 10, and a heating element 20 containing a temperature sensing body 202 and a heating body 201 is arranged within the accommodation space 101, and a control member is coupled to the heating element 20. In this way, the temperature sensing body 202 can monitor the surface temperature of the heating element 20. When the surface of the heating element 20 reaches the preset temperature, the control member can control the heating body 201 to stop heating, thereby preventing the heating device from dry burning and being damaged. By setting the heating element 20 as a ceramic body 203, the heating body 201 generates heat more uniformly during heating, and the heating range is wide, so the energy consumption is low during heating. By arranging a cover plate 70 with a second sealing ring 504 at one end of the housing 10 and arranging a pressing plate 702 within the cover plate 70, the heating element 20 installed within the accommodation space 101 can be fixed, and the liquid in the heating device can be prevented from overflowing. By arranging flow channel partitions 30 in layers with the heating element 20 within the accommodation space 101, the flow channels of the liquid can be evenly divided, so that the heating body 201 can uniformly heat the liquid inside the accommodation space 101. By arranging a water inlet pipe 401 and a water outlet pipe communicating with the accommodation space 101 at one end of the housing 10 and arranging the water inlet pipe 401 close to the bottom wall of the housing 10, when the liquid is introduced into the interior of the accommodation space 101, it can be introduced into the interior of the accommodation space 101 from the bottom of the housing 10, and the liquid can be uniformly heated, thereby preventing waste of resources caused by continuously heating the heated liquid. By arranging the first sensor 501 and the second sensor 502, the temperature of the liquid in the water inlet pipe 401 and the drain pipe 402 can be monitored. By arranging a grounding plate 60 at one end of the housing 10 away from the cover plate 70, the heating device can be grounded, ensuring the safety of the heating device and personnel during the operation of the heating device.

[0038] The present application also provides an intelligent bathroom, which includes a heating device. The heating device is disposed inside the intelligent bathroom and is the heating device of any one of the above.

[0039] The above are only the embodiments of the present application, and thus do not limit the patent scope of the present application.
