In these embodiments, by providing the housing assembly 94, the parts such as the pumping device 7, the heating device 3, and the liquid storage tank 1 can be sealed and protected by the housing assembly 94, so that the parts such as the pumping device 7, the heating device 3, and the liquid storage tank 1 can be prevented from being exposed to the air for a long time, and the waterproof and dustproof performance of the parts such as the pumping device 7, the heating device 3, and the liquid storage tank 1 can be improved.

As shown in fig. 7, an embodiment of the second aspect of the present invention provides a control method for a liquid heating container, for controlling the liquid heating container shown in fig. 1 to 6, and as shown in fig. 7, the control method for a liquid heating container includes: step 102, judging whether the liquid in the liquid storage tank meets a preset condition or not; and 104, opening the water outlet channel under the condition that the liquid in the liquid storage tank meets the preset condition, and closing the water outlet channel under the condition that the liquid in the liquid storage tank does not meet the preset condition.

According to the control method of the liquid heating container provided by the embodiment of the invention, the control method can be particularly used for the liquid heating container such as a hot water kettle and the like, and the control method can firstly judge whether the liquid in the liquid storage tank 1 meets the preset conditions or not, and only opens the valve 22 to open the water outlet channel for water outlet under the condition that the preset conditions are met, so that when the liquid outlet channel 2 starts to discharge the liquid, the temperature, the liquid amount and the like in the liquid storage tank 1 can meet the preset requirements, such as the liquid amount meeting the user requirements or the temperature meeting the user requirements, and the liquid heating container can continuously discharge the water with the temperature or the liquid amount required by the user. When the liquid in the liquid storage tank 1 is judged not to meet the preset condition, the valve 22 is closed to close the water outlet channel, so that the product cannot be drained when the temperature is insufficient or the liquid amount is insufficient.

In any of the above embodiments, preferably, the step of determining whether the liquid in the liquid storage tank 1 satisfies the preset condition specifically includes: judging whether the temperature of the liquid in the liquid storage tank 1 meets the preset temperature requirement or not; and/or judging whether the liquid volume of the liquid in the liquid storage tank 1 meets the preset liquid volume requirement.

In these embodiments, the temperature measuring member 5 may be arranged to detect the temperature of the liquid in the liquid storage tank 1, so that the control device 4 can control the opening and closing of the valve 22 according to the temperature detected by the temperature measuring member 5 and the preset temperature requirement. Therefore, the temperature of the water can be reasonably controlled, so that the temperature of the water discharged from the liquid outlet channel 2 can reach the temperature required by a user, and the water is prevented from directly flowing out when the water is not heated to a proper temperature. Simultaneously, can set up liquid level detection spare 6 and detect the liquid level in the liquid reserve tank 1, just so make controlling means 4 can control opening and closing of valve 22 according to the liquid level that liquid level detection spare 6 detected with predetermine the liquid level requirement, just so can store liquid in liquid reserve tank 1 after a certain amount in concentrate the required water of discharge user, alright avoid the intermittent outflow of liquid like this.

A method of controlling a liquid heating vessel according to another embodiment of the present invention is described with reference to fig. 8, which includes the following steps in a control scheme:

step 202, judging whether the liquid in the liquid storage tank meets a preset condition.

And 204, opening the water outlet channel under the condition that the liquid in the liquid storage tank meets the preset condition, and closing the water outlet channel under the condition that the liquid in the liquid storage tank does not meet the preset condition.

And step 206, stopping pumping the liquid into the liquid storage tank or reducing the speed of pumping the liquid into the liquid storage tank when the liquid level in the liquid storage tank is higher than or level to a preset position. In this step, can rationally set up a liquid level position, preset the position promptly to judge how much of the liquid in the liquid reserve tank 1, controlling means 4 alright like this based on the liquid level position (preset the position promptly) and the liquid level that liquid level detection piece 6 detected control pumping device 7 open and close, specifically, can be when the liquid level in the liquid reserve tank 1 is less than preset the position, control pumping device 7 and supply water to liquid reserve tank 1, and when the liquid level in the liquid reserve tank 1 is higher than or equal to preset the position, control pumping device 7 stop pumping liquid or reduce the speed of pumping liquid. And the mounting height of the steam outlet is higher than the preset position. This prevents the liquid level from exceeding the vapor outlet and escaping from the vapor outlet.

Step 206 may be performed before step 202, after step 202, or simultaneously with step 202.
