Problems solved by technology

[0003] However, in the after-sales statistics of the product, there are cases where the user does not use the smart toilet for a long time when traveling, causing the toilet to automatically enter the sleep mode, or turn off the heating function, and the water in the internal water tank is not drained at the same time; due to the low temperature, the smart toilet The water storage tank of the toilet is cracked due to the freezing of water inside; when the user uses it again, the smart toilet and the leakage protection device in the user's home are activated due to water leakage

Embodiment 1

[0017] Such as figure 1 As shown, the water tank heating control system includes a water tank heater, a water tank heating control circuit, a controller, and a water tank temperature sensor. When the warm water heating function and heat preservation are turned on, the water tank temperature sensor transmits the temperature in the water tank to the controller and controls Whether to heat the water tank; if heating is required, the controller sends a heating signal to the water tank heating control circuit, and the water tank heater heats the water tank through the water tank heating control circuit.

[0018] In order to achieve the purpose of preventing the internal water storage tank from freezing and cracking, in the design of the system, after the warm water heating function is turned off or the machine automatically sleeps, the temperature inside the water tank is regularly sampled, and the program actively sets the water temperature when it is turned off. The heat preservat...

Embodiment 2

[0026] In this embodiment, in order to achieve the purpose of preventing the internal water storage tank from freezing and cracking, when the system is designed, after the warm water heating function is turned off or the machine automatically sleeps, the temperature inside the water tank is regularly sampled, and the program actively sets the water temperature when it is turned off. Keep warm at -2°C. If the system detects that the temperature in the water tank is lower than -2°C, it will start the heater to heat the water for a few seconds and then turn it off. To maintain the water temperature in the water tank higher than the freezing point, to prevent it from freezing and cracking the water tank.

[0027] The invention provides a method for proactively preventing a water tank from freezing and cracking, which comprises the following steps:

[0028] Step 1. Determine the sleep state of the machine and the water temperature setting switch; if the machine is in sleep state o...

Embodiment 3

[0035] In this embodiment, in order to achieve the purpose of preventing the internal water storage tank from freezing and cracking, when the system is designed, after the warm water heating function is turned off or the machine automatically sleeps, the temperature inside the water tank is regularly sampled, and the program actively sets the water temperature when it is turned off. Heat preservation temperature to 10°C. If the system detects that the temperature in the water tank is lower than 10°C, it will start the heater to heat the water for a few seconds and then turn it off. To maintain the water temperature in the water tank higher than the freezing point, to prevent it from freezing and cracking the water tank.

[0036] The invention provides a method for proactively preventing a water tank from freezing and cracking, which comprises the following steps:

[0037] Step 1. Determine the sleep state of the machine and the water temperature setting switch; if the machine...

Abstract

The invention discloses a method for actively preventing a water tank from freezing and cracking. The method for actively preventing the water tank from freezing and cracking comprises the following steps of (1) judging a dormant state of a machine and the on and the off of water temperature setting; if the machine is at the dormant state or the water temperature setting is off, entering a step (2); and otherwise, repeating the step (1) once; (2) reading the temperature of a water temperature sensor in the water tank; (3) according to the temperature of the water temperature sensor, judging whether the temperature of the water tank is lower than a setting value or not; if the temperature of the water tank is lower than the setting value, entering the step (4); and otherwise, entering the step (1); (4) starting a water tank heater to heat water in the water tank; and (5) after heating for a period of time, shutting down the water tank heater, and entering the step (1). The method for actively preventing the water tank from freezing and cracking provided by the invention is improved on a water temperature heating system of an original intelligent pedestal pan, and water can be actively heated when a heating function of the machine is turned off or the machine is not used for a long time and automatically enters the dormant state, so that a heat preservation range cannot be too low, and the water tank of the intelligent pedestal pan can be prevented from freezing and cracking.

Description

technical field [0001] The invention relates to a method for actively preventing a water tank from freezing and cracking, which is used for an intelligent toilet and belongs to the field of electronics. Background technique [0002] For any kind of equipment that stores water, if the water in the storage freezes, it cannot be used if it is light, and it will cause the water storage tank to crack if it is serious, which will endanger the safety of the equipment. In the design process of the machine, turning off the heat preservation and dormancy means ignoring the internal temperature of the water tank and turning off the heating function to achieve energy saving or meet customer expectations. [0003] However, in the after-sales statistics of the product, there are cases where the user does not use the smart toilet for a long time when traveling, causing the toilet to automatically enter the sleep mode, or turn off the heating function, and the water in the internal water ta...
