Usually, the bottom wall part 233 and the side wall part 234 of the float seat 203 are provided with a water outlet 231 so as to make the movement of the float 204 more accurate. By forming a plurality of limiting ribs 235 at intervals on the inner surface of the side wall portion 234 , the up and down movement of the float 204 in the float seat 203 can be limited to avoid deflection of the float 204 .

In some embodiments, the water storage device 100 of the embodiment of the present invention further includes: a water level monitoring circuit board 305 disposed in the receiving chamber 311 . The water level monitoring circuit board 305 is provided with a first magneto-sensitive resistor 351 and a second magneto-sensitive resistor 352, and the upper and lower positions and front and rear positions of the first magneto-sensitive resistor 351 and the second magneto-sensitive resistor 352 on the water level monitoring circuit board 305 are different. , to indicate the status of the kettle 200 based on the interaction between the first magnetoresistor 351 , the second magnetoresistor 352 and the magnetic member 243 . The status of the kettle 200 may include a water level status, a position status, and an access status. The state of the water level of the kettle 200 may include a state without water filling and a state of needing water, and the position state of the kettle 200 may include a state of being placed in place and a state of not being placed in place. The in and out states of the kettle 200 may include the kettle 200 being put in and the kettle 200 being removed.

As shown in FIG. 14 , in some embodiments, the kettle 200 is configured to be placed under the device cover 300 from front to back. The water level monitoring circuit board 305 is arranged above the magnetic member 243 along the front and rear direction, the projection of the first magnetoresistor 351 on the vertical plane is below the projection of the second magnetoresistor 352, and the projection of the first magnetoresistor 351 on the horizontal plane It is behind the projection of the second magnetoresistor 352 . So that when the kettle 200 has different water level states, different position states, and different entry and exit states, the interactions between the first magnetoresistor 351, the second magnetoresistor 352 and the magnetic member 243 are obviously different, that is to say, the first Whether magnetoresistor 351 and second magnetoresistor 352 have signals, the order of the signals of first magnetoresistor 351 and second magnetoresistor 352, etc. will be different, thus making it possible to , the interaction between the second magnetoresistor 352 and the magnetic member 243 to indicate the water level status, position status, and access status of the kettle 200 .

Specifically, the following conditions are satisfied among the magnetic member 243, the first magneto-sensitive resistor 351, and the second magneto-sensitive resistor 352:

v≤r;

u+v>r;

u+v-w≤r;

In the formula, r is the effective radius of action of the magnetic part 243; v is the farthest up and down distance between the first magneto-resistor 351 and the magnetic part 243; u is the distance between the first magneto-resistor 351 and the second magneto-resistor 352 The up and down distance; w is the up and down movable distance of the magnetic member 243 in the kettle 200 . The design purpose of the furthest up and down distance v≤r between the first magneto-sensitive resistor 351 and the magnetic piece 243 is that when the kettle 200 is placed under the device cover 300 correctly, the first magneto-sensitive resistor 351 can feel the force of the magnetic piece 243 Magnetic, there is a signal. And when the first magnetoresistor 351 has no signal, it means that the kettle 200 is not placed in place. The state of not placing the kettle 200 in place includes two situations, one is that the kettle 200 is not placed under the device cover 300, for example, the kettle 200 is placed in other storage compartments of the refrigerator 400 or is removed from the refrigerator 400; 200 is placed under the device cover 300, but not fully in place.

The effective radius of action of the magnetic part 243 and the distance limiting conditions of the first magnetoresistor 351 and the second magnetoresistor 352 can realize the monitoring of the liquid level in the kettle 200: when the water in the kettle 200 does not support the float 204 When u+v>r, the second magnetoresistor 352 cannot feel the magnetic force of the magnetic part 243, and there is no signal, indicating that the liquid level is too low and water needs to be filled; when the water in the kettle 200 lifts the float 204, u+ v-w≤r, the second magnetoresistor 352 can sense the magnetic force of the magnetic member 243 and there is a signal, indicating that water injection is not required.

The magnetic force of the magnetic member 243 is related to the type of the magnetic member 243 . As mentioned above, the magnetic member 243 can be a magnet. Magnets of different specifications have different effective radius r of magnetic force. Generally, considering the cost factor, the water storage device 100 of the embodiment of the present invention adopts a magnet with an effective magnetic force radius r≤20mm as the magnetic member 243 .

The projection of the first magnetoresistor 351 on the horizontal plane is behind the projection of the second magnetoresistor 352 , that is to say, there is a distance between the first magnetoresistor 351 and the second magnetoresistor 352 . Therefore, whether the kettle 200 is put in or removed can be judged by the order of whether the first magnetoresistor 351 and the second magnetoresistor 352 have signals. The front-rear distance m between the first magnetoresistor 351 and the second magnetoresistor 352 generally has a value ≥ 10 mm. For example, assuming that the kettle 200 is filled with water, when the second magnetoresistor 352 has a signal first, then the first magnetoresistor 351 has a signal, indicating that the kettle 200 is put in; There is no signal behind the second magnetoresistor 352, indicating that the kettle 200 is removed.

A convex portion 365 is formed on the circuit board base 306 , and the portion of the water level monitoring circuit board 305 where the second magnetoresistor 352 is disposed overlaps the convex portion 365 of the circuit board base 306 . By forming a convex portion 365 on the circuit board base 306, the part of the water level monitoring circuit board 305 where the second magnetoresistor 352 is set is lapped on the convex portion 365 of the circuit board base 306, so that the water level monitoring circuit board 305 is placed on the circuit board. The base 306 can be fixed more firmly.

The projection of the left and right width of the convex portion 365 of the circuit board base 306 on the horizontal plane covers the handle 211 of the kettle body 201 . A protrusion 2212 is formed on the cover body 221 of the cover 202 corresponding to the protrusion 365 of the circuit board base 306 , and the front end of the protrusion 2212 of the cover 202 covers the upper end of the handle 211 .

S110: Control the reminding device 902 to send out a displacement reminder.

After the kettle 200 is put into the refrigerator 400, it is first judged whether the kettle 200 is placed in place. Since the first magneto-sensitive resistor 351 has a signal after the kettle 200 is put in place, it can be determined whether the kettle 200 is put in place by judging whether the first magneto-sensitive resistor 351 has a signal. Therefore, when there is no signal from the first magnetoresistor 351 , it means that the kettle 200 is not correctly placed under the device cover 300 , and at this time, the control reminder device 902 sends out a displacement reminder. When the first magnetoresistor 351 has a signal, it indicates that the kettle 200 has been placed in place, and at this time, it is judged whether the kettle 200 needs to be filled with water. Here, in order to simplify the control process of water filling, it can be set that when the float 204 is lifted by water, it is considered that the kettle 200 has been filled with water, and water filling is no longer required. That is to say, when the second magnetoresistor 352 has a signal, it is considered that the kettle 200 has been filled with water, and there is no need to add water. Thus, when the second magneto-sensitive resistor 352 has a signal, the electric switch device 901 is controlled to be turned off, and no water is poured into the kettle 200 . And when the second magnetoresistor 352 has no signal, the electric switch device 901 is controlled to open, and water is poured into the kettle 200 until the second magnetoresistor 352 has a signal.

The control device 900 is used to control the action of the electric switch device 901 based on the status information of the kettle. The kettle state information can be determined through a preset mapping relationship, wherein the mapping relationship specifies the signal state of the first magneto-resistor 351, the signal state of the second magneto-resistor 352, the first magneto-resistor 351 and the second magneto-resistor 352 The signals of the two magnetoresistors 352 are sequentially corresponding to the status information of the kettle. For example, it is stipulated in the mapping relationship that "the first magnetoresistor 351 has a signal, and the second magnetoresistor 352 has no signal" and the corresponding pot status information is "need to fill water". For another example, it is stipulated in the mapping relationship that "the first magneto-sensitive resistor 351 has a signal first, and the second magneto-sensitive resistor 352 has a signal later", and the corresponding pot status information is "water is full".
