Description

[0002] With the development of technology, the degree of intelligence of household appliances is getting higher and higher. For example, smart water heaters and smart toilets can monitor the heated water temperature in real time and control the heating temperature at any set value by installing a temperature sensor inside the water heater, heating according to the preset temperature, or cutting off the heating power supply in time to protect the water heater when the heating temperature is too high.

[0003] During the implementation of the embodiments of the present application, the inventors discovered that the existing installation method is to insert the temperature sensor into the shell of the water heater. Due to the presence of air between the ceramic heating plate and the temperature sensor, the efficiency of temperature transfer is reduced, resulting in a lag in the temperature measurement of the ceramic heating plate by the temperature sensor. The ceramic heating plate can only be powered off or the heating power can be reduced when the ceramic heating plate is already dry-burning or close to dry-burning, which can easily cause permanent damage to the ceramic heating plate.

[0024] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0025] See also Figure 1 and Figure 5The present application provides an anti-dry-burning heater 100, comprising a shell 10, a heating component 20, a temperature sensor 30 and a heat conductor 40. The shell 10 is provided with a liquid channel 11 for liquid flow inside, the heating component 20 is arranged on the shell 10, and at least a part of the heating component 20 is located in the liquid channel 11, and the heating component 20 is configured to generate heat when electrically conductive, so as to heat the liquid in the liquid channel 11. The heat conductor 40 is arranged on the shell 10, and at least a part of the heat conductor 40 is abutted against the heating component 20, the temperature sensor 30 is connected to the heat conductor 40, the temperature sensor 30 measures the temperature of the heating component 20 through the heat conductor 40, and sends the measured temperature information to an external controller to achieve temperature control of the heating component 20.

[0026] In the present application, a heat conductor 40 is arranged between the temperature sensor 30 and the heating component 20. By utilizing the good thermal conductivity of the heat conductor 40, the loss in the heat transfer process can be reduced and the accuracy of the measurement of the temperature sensor 30 can be improved. At the same time, the speed of solid heat transfer is greater than the speed of air heat transfer, which enables the temperature sensor 30 to quickly measure the temperature of the heating component 20, effectively solving the problems of low measurement accuracy and serious measurement lag caused by heat transfer through air between the temperature sensor 30 and the heating component 20 in the prior art.

[0027] It is understood that in order to ensure the heat transfer efficiency, the heat conductor 40 in the present application should be made of a material with good thermal conductivity, for example, the heat conductor 40 is made of one of metal, graphite or graphite alloy. In some embodiments, at least part of the heat conductor 40 is made of brass, and the brass is respectively abutted against the heating component 20 and the temperature sensor 30 to ensure the heat transfer. Further, the heat conductor 40 is made entirely of brass.

[0028] For the above-mentioned heating element 20, please refer to Figure 2 and Figure 3 In order to extend the path of the liquid channel 11 inside the housing 10, the liquid channel 11 is arranged in an S-shaped circuitous manner. Therefore, the heating component 20 can be arranged at different positions of the liquid channel 11. As an example, please refer to Figure 3 The heating component 20 includes a first heating sheet 21 and a second heating sheet 22 which are spaced apart from each other. The first heating sheet 21 and the second heating sheet 22 are respectively arranged at different positions of the liquid channel 11. The heat conducting member 40 is arranged between the first heating sheet 21 and the second heating sheet 22, and the first end 41 of the heat conducting member 40 abuts against the first heating sheet 21 and the second heating sheet 22 at the same time.

[0029] Through the above structure, the temperatures on the first heating sheet 21 and the second heating sheet 22 can be transferred to the temperature sensor 30 through the heat conductive member 40. In addition, the heat conductive member 40 is arranged between the first heating sheet 21 and the second heating sheet 22, so that the time and path for the heat on the first heating sheet 21 and the second heating sheet 22 to be transferred to the heat conductive member 40 are roughly the same, thereby overcoming the problem in the prior art that the temperature sensor 30 is only arranged on the same side of the first heating sheet 21 and the second heating sheet 22, resulting in unequal temperature transfer paths of the two heating sheets, thereby reducing the accuracy of temperature measurement.

[0030] For the above-mentioned heat conducting member 40, please refer to Figure 4 The heat conducting member 40 is provided with a receiving cavity 43 and an opening 44 for connecting the receiving cavity 43 with the outside, wherein the opening 44 is arranged opposite to the cavity bottom 45 of the receiving cavity 43. Specifically, the cavity bottom 45 of the receiving cavity 43 is close to the first end 41 of the heat conducting member 40, and the opening 44 is located at the second end 42 of the heat conducting member 40. The first end 41 and the second end 42 of the heat conducting member 40 are arranged opposite to each other, and the temperature sensor 30 is arranged in the receiving cavity 43. By arranging the receiving cavity 43 on the heat conducting member 40 to place the temperature sensor 30, on the one hand, it is convenient to assemble and connect the temperature sensor 30 with the heat conducting member 40, and on the other hand, it can make the temperature sensor 30 closer to the first heating plate 21 and the second heating plate 22 in the heating component 20, shortening the distance of heat transfer. At the same time, the temperature sensor 30 located in the receiving cavity 43 can receive heat from the cavity bottom 45 of the receiving cavity 43 and the side wall of the receiving cavity 43, so that the measurement area of ​​the temperature sensor 30 is more three-dimensional. Compared with the temperature measurement of a single point or a single surface, the above structure can further improve the measurement accuracy of the temperature sensor 30.

[0031] In some embodiments, to further improve the heat transfer efficiency, thermal grease (not shown) is filled between the temperature sensor 30 and the heat conductor 40 in the accommodating cavity 43 , thereby eliminating the air gap between the temperature sensor 30 and the heat conductor 40 .

[0032] See also Figure 4 and Figure 5 The second end 42 of the heat conducting member 40 is provided with a flange portion 46, which extends in a direction away from the central axis of the accommodating cavity 43, that is, the flange portion 46 extends in a radial direction of the heat conducting member 40 and away from the center of the heat conducting member 40. The flange portion 46 abuts against the housing 10, thereby limiting the displacement of the heat conducting member 40.

[0033] See also Figure 2In some embodiments, a first plane 12 is provided on the area of ​​the shell 10 facing the flange portion 46, and a second plane 461 is provided on the side of the flange portion 46 facing the first plane 12. The first plane 12 abuts against the second plane 461, thereby sealing the gap between the heat conductor 40 and the shell 10 to prevent the liquid in the liquid channel 11 from leaking from the gap.

[0034] See also Figure 5 In other embodiments, in order to further improve the sealing performance between the heat conductive member 40 and the housing 10, the anti-dry-burning heater 100 further includes a sealing member 50, which is disposed between the flange portion 46 and the housing 10. When the heat conductive member 40 is assembled on the housing 10, the sealing member 50 is squeezed and deformed to seal the gap between the heat conductive member 40 and the housing 10. The sealing member 50 may be an elastic rubber ring.

[0035] In some embodiments, see Figure 5 The anti-dry-burning heater 100 further includes a cover plate 60, which is connected to the heat-conducting member 40 and the housing 10 respectively to fix the heat-conducting member 40 to the housing 10. At the same time, the cover plate 60 is also connected to the temperature sensor 30 to fix the temperature sensor 30 to the heat-conducting member 40. The cover plate 60 can be connected to the housing 10 by screwing, clamping, bonding, welding or any other connection method in the prior art.

[0036] In some embodiments, since the cover plate 60 is directly exposed to the outside world, it is necessary to reduce the heat transfer to the cover plate 60 as much as possible to avoid high temperature scalding the operator or user. The cover plate 60 is preferably made of a material with good thermal insulation performance. As some examples, the cover plate 60 is made of plastic or ceramic.

[0037] The present application also provides an embodiment of a smart bathroom equipment, which includes at least a controller and the above-mentioned anti-dry-burning heater 100. The controller is electrically connected to the heating component 20 and the temperature sensor 30 in the anti-dry-burning heater 100. The controller controls the heating power of the heating component 20 by receiving the measurement result of the temperature sensor 30, thereby realizing the intelligence level of the smart bathroom equipment. For the specific structure and function of the anti-dry-burning heater 100, please refer to the above-mentioned embodiment, which will not be repeated here.

[0038] The anti-dry-burning heater 100 of the embodiment of the present application includes a housing 10, a heating component 20, a temperature sensor 30 and a heat conductor 40. The interior of the housing 10 is provided with a liquid channel 11 for liquid flow, the heating component 20 is arranged on the housing 10, and at least a part of the heating component 20 is located in the liquid channel 11. The heat conductor 40 is arranged on the housing 10, and at least a part of the heating component 20 is abutted against the heating component 20, the temperature sensor 30 is connected to the heat conductor 40, and the temperature sensor 30 measures the temperature of the heating component 20 through the heat conductor 40. By arranging the heat conductor 40 between the temperature sensor 30 and the heating component 20 and utilizing the good thermal conductivity of the heat conductor 40, the loss in the heat transfer process can be reduced, the accuracy of the temperature sensor 30 measurement can be improved, and the problem of low measurement accuracy and serious measurement lag caused by heat transfer between the temperature sensor 30 and the heating component 20 through air in the prior art is effectively solved.
