[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] First, see Figures 1 to 7 The utility model provides an intelligent hot water induction cooker, comprising an induction cooker body 1, a control panel 2, a metal water pipe 3, an electric-controlled three-way valve 4, a tap water pipe 5, an insulated water tank 6 and a water pump 7, wherein the metal water pipe 3 has a water inlet 10 and a water outlet 11;

[0027] The control panel 2 is fixedly connected to the induction cooker body 1 and is located on the inner side of the induction cooker body 1. The metal water pipe 3 is fixedly connected to the induction cooker body 1 and is located on one side of the induction cooker body 1. The water pump 7 is connected to the insulated water tank 6 and is located on one side of the insulated water tank 6. The electrically controlled three-way valve 4 is respectively connected to the water pump 7 and to the water inlet 10 and is located between the water pump 7 and the water inlet 10. The water outlet 11 is connected to the insulated water tank 6. The tap water pipe 5 is connected to the electrically controlled three-way valve 4 and is located on one side of the electrically controlled three-way valve 4.

[0028] In this embodiment, the electromagnetic valve on the side of the electrically controlled three-way valve 4 close to the heat-insulating water pump 7 is opened through the control panel 2, the water pump 7 is started, and the water inlet 10 and the water outlet 11 of the metal water pipe 3 are opened to form a circulation system, so that the water (the water in the metal pipe) is circulated and heated in the system; when the water volume in the heat-insulating water tank 6 drops to a preset low water point, the water pump 7 is stopped, the electromagnetic valve on the side of the electrically controlled three-way valve 4 close to the heat-insulating water pump 7 is closed, and the electric valve on the side of the electrically controlled three-way valve 4 close to the tap water pipe 5 is opened, so that the tap water enters the system for circulation and heating, and when the water level in the heat-insulating water tank 6 reaches the preset low water point, the water pump 7 is stopped. When the high water point is set, the electric valve on the side of the electric-controlled three-way valve 4 close to the tap water pipe 5 is closed; the electromagnetic valve on the side of the electric-controlled three-way valve 4 close to the heat-insulating water pump 7 is opened again, and the water pump 7 is started, so that the water in the heat-insulating water tank 6 is circulated and heated in the system, and circulates back and forth. The induction cooker absorbs excess internal heat through water circulation heating technology, which can effectively improve the service life of the induction cooker product and increase the effective utilization of excess heat during the operation of the induction cooker. Energy conservation and emission reduction make contributions to human environmental protection, and solve the problem of excess heat around the stove plate during the operation of the induction cooker, which causes the internal ambient temperature of the induction cooker to become high and accelerates the aging of the induction cooker.

[0029] Furthermore, the insulated water tank 6 has a faucet 8 and a water temperature probe 9, the faucet 8 is located at the bottom of the insulated water tank 6, and the water temperature probe 9 is located at the bottom of the insulated water tank 6.

[0030] In this embodiment, the faucet 8 is used to open the insulated water tank 6, so that the hot water in the insulated water tank 6 can flow out for washing vegetables, hands and dishes, etc. The water temperature probe 9 is an external NTC used to detect the temperature in the insulated water tank 6.

[0031] Second, see Figure 8 The utility model also provides an intelligent hot water induction cooker control method, comprising the following steps:

[0032] S1 After the induction cooker body 1 is working, the electromagnetic valve on the side of the electric-controlled three-way valve 4 close to the heat-insulating water pump 7 is opened, the water pump 7 is started, and the water inlet 10 and the water outlet 11 of the metal water pipe 3 are opened to form a circulation system so that water circulates and heats in the system;

[0033] When the water level in the S2 insulated water tank 6 drops to a preset low water level, the water pump 7 stops, the electromagnetic valve on the side of the electric-controlled three-way valve 4 close to the insulated water pump 7 is closed, and the electric valve on the side of the electric-controlled three-way valve 4 close to the water pipe 5 is opened, so that the tap water enters the system for circulation and heating. When the water level in the insulated water tank 6 reaches a preset high water level, the electric valve on the side of the electric-controlled three-way valve 4 close to the water pipe 5 is closed;

[0034] S3 opens the electromagnetic valve on the side of the electric-controlled three-way valve 4 close to the heat-insulating water pump 7 again, starts the water pump 7, and makes the water in the heat-insulating water tank 6 circulate and heat in the system, and circulates back and forth all the time.

[0035] When the induction cooker body 1 is turned on, the water level and water temperature in the thermal insulation water tank 6 are first detected. Then, it is determined whether the circulation heating function needs to be turned on according to the detected water temperature and water level. Only when it is detected that the water volume in the thermal insulation water tank 6 exceeds the high water level and the water temperature exceeds 90°C, the circulation heating function of the system stops working.

[0036] The water temperature in the water tank is detected by an external NTC, which is divided into 3 states: when the water temperature is T<35℃, the LED light is green; when the water temperature is 55℃≥T≥35℃, the LED light is yellow; when the water temperature is T>55℃, the LED light is red;

[0037] The data obtained by "NTC" detection is transmitted to the control board 2 to identify the current water temperature. If T is less than 35°C, the "LED-COM1" terminal is at a low level, "LED3" outputs a high level, and the LED is displayed in green, indicating that the water in the current insulated water tank 6 is at room temperature and can be used directly without affecting safety; if 55°C ≥ T ≥ 35°C, the "LED-COM1" terminal is at a low level, "LED2" outputs a high level, and the LED is displayed in orange, indicating that the water in the current insulated water tank 6 is at a medium temperature and can be used directly, but safety precautions are required; if T is greater than 55°C, the "LED-COM1" terminal is at a low level, "LED1" outputs a high level, and the LED is displayed in red, indicating that the water in the current insulated water tank 6 is at a high temperature and must be used with caution and safety precautions;

[0038] The amount of water in the insulated water tank 6 is determined by the signal transmitted back by the external reed switch. If the signal detected at the "SW1" end is high, it reflects that the water level in the insulated water tank 6 is in a high water level state. According to the signal, it is necessary to open the solenoid valve on the side of the electrically controlled three-way valve 4 connected to the insulated water tank 6, start the water pump 7, and allow the water in the insulated water tank 6 to circulate and heat in the system. If the signal detected at the "SW2" end is high, it reflects that the water level in the insulated water tank 6 is in a low water level state. According to the signal, it is necessary to open the solenoid valve on the side of the electrically controlled three-way valve 4 connected to the tap water pipe 5, so that the tap water enters the system for circulation and heating.

[0039] The information of the water volume in the insulated water tank 6 is confirmed. If the water volume in the insulated water tank 6 is above the high water level, then the solenoid valve on one side of the electric-controlled three-way valve 4 connected to the insulated water tank 6 needs to be opened. First, the "DCF2" port of the control board 2 outputs a PWM signal to turn on the transistor Q7, then the transistor Q6 is turned on again, and finally the solenoid valve DCF2 works, turning on the solenoid valve switch, and then the "MOT" port of the electric control board outputs a high-level signal again, turning on the transistor Q2, then the MOS tube Q3 is turned on again, and finally the water pump 7 starts working, allowing the water in the insulated water tank 6 to enter the circulation heating device of the system. If the water volume in the insulated water tank 6 is below the low water level, vice versa.

[0040] The water volume in the insulated water tank 6 is detected and confirmed. If the water volume in the insulated water tank 6 is below the low water level, the electromagnetic valve on the side of the electric three-way valve 4 connected to the tap water pipe 5 needs to be opened. The "DCF1" port of the electric control board outputs a PWM signal, which turns on the transistor Q5, then the transistor Q4, and finally the electromagnetic valve DCF1 works, turns on the electromagnetic valve switch, and allows the tap water to enter the circulation heating device of the system. If the water volume in the insulated water tank 6 is above the high water level, vice versa.

[0041] The above disclosure is only a preferred embodiment of an intelligent hot water induction cooker and a control method of the utility model. Of course, this cannot be used to limit the scope of rights of the utility model. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the utility model still fall within the scope covered by the utility model.
