Heating equipment and its control device and method

Abstract

The invention discloses a heating device and its control device and method, wherein the control device includes: an over-temperature protector arranged in the power supply circuit of the heating element of the heating device; a detection device connected with the over-temperature protector , used to detect the feedback voltage used to characterize the working state of the over-temperature protector, the working state includes an open state and a closed state; a prompting device, connected to the detection device, is used to send out according to the feedback voltage corresponding prompt information. After the over-temperature protector is disconnected, it is detected by the detection device, and the corresponding feedback voltage is obtained. The prompt information issued by the control prompt device on behalf of the failure reminds the user to power off and restart. After the user powers off, the over-temperature protector closes and detects The feedback voltage detected by the device controls the prompting device to send out prompting information representing normal operation. It can enable the user to know the status of the heating device more clearly, prompt the user for a specific operation, and provide the user with a better experience.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a heating device and its control device and method. Background technique [0002] With the development of society and the improvement of human living standards, people have higher requirements for the functions and experience effects of household electrical appliances. As a heating appliance, electric heaters are very important for temperature control to ensure safety. In the prior art One part uses the combination of automatic reset thermostat and fuse to achieve temperature control. However, once the fuse is broken, it needs to be replaced again, which is more complicated to replace and increases the after-sales burden; the other usually uses a power-off reset thermostat to play a role. The function of temperature control protection, but if the power failure resets, the thermostat needs to be powered off before it can be reset. After the thermostat is disconnected,...

[0002] With the development of society and the improvement of human living standards, people have higher requirements for the functions and experience effects of household electrical appliances. As a heating appliance, electric heaters are very important for temperature control to ensure safety. In the prior art One part uses the combination of automatic reset thermostat and fuse to achieve temperature control. However, once the fuse is broken, it needs to be replaced again, which is more complicated to replace and increases the after-sales burden; the other usually uses a power-off reset thermostat to play a role. The function of temperature control protection, but if the power failure resets, the thermostat needs to be powered off before it can be reset. After the thermostat is disconnected, the load does not work. However, because the power supply of the electric heater is not turned off, the display panel displays normally. It is difficult for users to find that the electric heater is not working, which brings poor user experience to users
