Example two

The embodiment provides a water heater, the structure of which is the same as that of the first embodiment, and the first embodiment further defines the wireless detection piece as a wireless temperature sensor. The wireless temperature sensor is used for detecting the temperature of the inner wall of the non-metal liner 1; the controller is connected with heating element 2 and wireless temperature sensor communication respectively, and the controller can be when the temperature that wireless temperature sensor detected is unusual, and control heating element 2 stops the heating.

Through the cooperation of wireless temperature sensor and controller, whether the temperature that can in time detect non-metallic inner bag 1 has the high temperature unusual, if the temperature that detects is greater than preset temperature, then judge that there is the high temperature unusual, controller control heating element 2 stop work avoids non-metallic inner bag 1 to appear melting or the risk of burning through, can in time detect the potential safety hazard, guarantees the normal work of water heater and user's safety.

The abnormal temperature means that the temperature rise rate of the inner wall temperature of the non-metal liner 1 higher than the preset temperature or the inner wall temperature of the non-metal liner 1 is higher than the preset temperature rise rate, so as to avoid the damage of the non-metal liner 1.

In this embodiment, wireless temperature sensor inlays in 1 lateral wall of nonmetal inner bag, avoids the direct water contact in 1 with nonmetal inner bag of wireless temperature sensor, guarantees wireless temperature sensor's power consumption safety, also is favorable to guaranteeing nonmetal inner bag 1's sealing performance simultaneously. In addition, wireless temperature sensor inlays in 1 lateral wall of nonmetal inner bag, can also reduce the influence of other environmental factor to the testing result, helps improving the accuracy of temperature measurement result.

It can be understood that, when water exists in the nonmetal inner container 1, the heat of the heating component 2 received by the inner wall of the nonmetal inner container 1 is less, the temperature of the inner wall of the nonmetal inner container 1 stays in a safety range, and the potential safety hazard that the nonmetal inner container 1 is melted or burnt through cannot exist. When no water exists in the non-metal inner container 1, the heat of the heating component 2 is directly radiated to the inner wall of the non-metal inner container 1, the temperature of the inner wall of the non-metal inner container 1 rises quickly and greatly, and the non-metal inner container 1 has a potential safety hazard of melting. Therefore, in the embodiment, the proper preset temperature value is set, so that dry burning can be strictly prevented, and the safety performance of the water heater is further improved.

In order to detect the abnormal temperature condition more timely, the wireless temperature sensor is arranged at the position of the non-metal liner 1 close to the heating component 2, and detects the temperature of the position of the non-metal liner 1 which is most likely to be damaged by high temperature.

Specifically, the level of heating element 2 sets up in non-metallic inner bag 1, and is close to the bottom of non-metallic inner bag 1 to the convection current of the water in non-metallic inner bag 1 is strengthened to the water of heating non-metallic inner bag 1 bottom, utilizes the characteristic that hot water upwards flows, cold water downward flow, thereby improves heating efficiency.

Correspondingly, the wireless temperature sensor is arranged at the bottom of the non-metal inner container 1, namely, the wireless temperature sensor is positioned below the heating assembly 2. The inner wall position of the non-metal inner container 1 corresponding to the wireless temperature sensor is close to the heating component 2, when the heating component 2 is dried, the heat received by the inner wall at the position is the most, and the temperature is correspondingly the highest. The temperature of the inner wall at the position can be detected in time, so that the nonmetal inner container 1 can be prevented from being melted in time.

Further, the number of wireless temperature sensors is provided with a plurality of, and a plurality of wireless temperature sensors are arranged along the length direction interval of heating element 2. Every wireless temperature sensor all is connected with the controller communication, and the controller judges whether need stop heating through a plurality of wireless temperature sensor's testing result to avoid the judgement error that single temperature measurement component 3 unusually leads to.

Specifically, after receiving the detection results of the plurality of wireless temperature sensors, the controller can reject abnormal data, and judges whether heating needs to be stopped or not according to comparison of the average value of the rest of data with the preset temperature or the preset temperature rise rate so as to improve the accuracy of the judgment result.
