The carrying platform 211 and the limiting wall 212 are jointly limited to form a storage cavity, and the storage cavity is slightly larger than the water storage pot 10. On the one hand, it is convenient to take and place the water storage pot 10, and on the other hand, it can be well Securely fix the water storage jug 10. The water storage jug 10 is placed on the carrying platform 211, and the limiting member 213 is located in the limiting groove 114, so that the water storage jug 10 is accommodated in the accommodating cavity and cannot be moved in the horizontal direction. Rotate freely.

The water supply structure 22 is located above the fixed structure 21 , and water is introduced into the water storage pot 10 from top to bottom. The water supply structure 22 includes a water supply pipe 221 , a water valve 222 electrically connected to the control system to control the water supply, and a water supply port 223 connected to the water connection port 121 when the water storage pot 10 is in the correct position. The water supply pipe 221 includes a water storage pipe 2211 connected to a water source, a filter 2212, and a water delivery pipe 2213 connected to the water supply port 223; the amount of water that can be stored in the inner shell of the water storage pipe 2211 is 0.5-3 times, preferably more than 1 times, so as to supply water to the water storage jug 10 at any time.

Certainly, the sensor may also include a first sensor for detecting the first sensor element and a second sensor for detecting the second sensor element respectively.

The sensor is fixed on the water supply mechanism 20, specifically, the sensor is set close to the sensor element to be detected to obtain an accurate detection signal; setting close to the sensor element to be detected means that the water storage pot 10 is located at the correct position. When in the position, the sensor is close to the sensing element. In this embodiment, the inductor is located in the fixed structure 21, especially in the receiving cavity. switch. The output signal such as the output voltage of the Hall element is related to the change of the magnetic field or magnetic flux detected by the Hall element. The Hall element detects the change of the magnetic flux, and outputs a signal based on the detected change of the magnetic flux; as the detected magnetic flux increases, the output signal also increases, and vice versa; thus the Hall element can detect a The position of the magnetic sensitive element changes relative to a reference point; of course, the Hall element can also detect whether the magnetic sensitive element is in the correct position. In short, the Hall switch judges the position of the sensing element through the change of the strength of the surrounding magnetic field, and then judges the position of the water storage pot 10 and the water level in the water storage pot 10 .

Specifically, when the sensor detects that the magnetic field or the magnetic field intensity generated by the first induction element is the largest, the water storage jug 10 is located at the correct position on the fixed structure 21, that is, the water receiving port 121 and the When the water supply port 223 is docked; and the sensor does not detect the magnetic field generated by the first induction element or detects that the magnetic field generated by the first induction element is lower than the strongest value, the water storage jug 10 is in an incorrect position , not available for water. The second induction element can move along the height direction of the water storage jug 10 as the water level in the water storage jug 10 rises or falls, so that the distance between the second induction element and the sensor is decreasing Or increase, so that the magnetic field detected by the sensor is weakened or strengthened, according to which the water level in the water storage jug 10 can be judged.

Please refer to Fig. 1 to Fig. 4, the utility model also provides a refrigerator 300 with the water supply device 100, so as to provide cold drinks. The refrigerator 300 includes a box body 310 , a door body 320 , and a refrigeration compartment surrounded by the box body 310 and the door body 320 . The water supply structure 22 includes an interface (unnumbered) connected to the water source on the outside of the refrigerator 300, which hides the water storage pipe 2211, the filter 2212 and the water valve 222 arranged in the box body 310 or the door body 320. The water supply port 223 for supplying water to the water storage pot 10 in the refrigerated compartment. The water storage pot 10 and the fixing structure 21 are arranged in the refrigerating room, so that users can take cold water at any time.

In this embodiment, the fixing structure 21 is arranged on the door body 320, specifically located on the top of the door body 320 and at the middle position in the width direction of the door body 320, so when the door body 320 is opened and pulled left and right It is not necessary to change the setting of the corresponding water supply structure 22 when changing. The water supply mechanism 20 is concealedly arranged on the top of the box body 310, and the water storage pipe 2211 is arranged against the wall of the inner tank so as to obtain cold energy from the refrigeration room, so that the water in the water storage pipe 2211 is also For cold water, to provide cold water to described water storage jug 10 in a very short time.

The utility model also provides an automatic water supply method for the water supply device 100, which includes the following steps: S1: placing the water storage pot 10 in the storage cavity; S2: detecting the induction element through a sensor And transmit the detection signal to the Chinese-English chip; S3: The central chip analyzes the detection signal to obtain an execution signal whether to open the water valve 222 for water supply; S4: The central chip opens or closes the water supply according to the execution signal. Said water valve 222.

After the water storage pot 10 is fixed on the fixed structure 21, the sensor first detects the sensing element to determine whether the water storage pot 10 is in the correct position; if the water storage pot 10 is in the correct position, the water valve 222 is turned on, the sensor continuously detects the change of the magnetic field intensity generated by the sensing element within a preset time without interruption, and obtains a series of changes. The inductor is a Hall element, and the sensing element is a magnetosensitive element.

The preset time is any specified period of time, such as 1s~30s, or 1s~5s, or 1ms~1s; the preset change amount is when the water storage pot 10 is filled with water or nearly full of water, when Supplying water to the water storage jug 10 within a preset period of time results in a change in the intensity of the magnetic field generated by the induction element. It can be seen from the above that the shorter the preset time, the better, and the smaller the corresponding preset change amount, the better, and the preset change amount is not enough to cause the water in the water storage jug 10 to overflow, so as to avoid waste water.

The preset amount of change within the preset time is closely related to the water supply speed and the volume of the water storage jug 10 during this period of time; A reference to the preset amount of change in time. Generally, the larger the volume of the water storage jug 10, the lower the water supply speed, and the longer the preset time; and the preset change amount is better if the sensor can detect the change amount of the magnetic field of the induction element, The preset variation should not be too large. In this embodiment, the preset change amount is small, specifically slightly smaller than the change amount of the sensing element when the water storage pot 10 is full. Therefore, when the measured variation is greater than the preset variation or far greater than 0, it means that the water storage pot 10 is not full, and the execution signal is to open the water valve 222; the water valve 222 continues to open until the The water storage jug 10 is taken away or the water storage jug 10 is filled with water before closing. When the measured variation is less than the preset variation or substantially close to 0, it indicates that the water in the water storage jug 10 is full or nearly full, and the execution signal is to close the water valve 222; if the water storage jug 10 If the water has been filled, the water valve 222 will be closed after the preset time.

It can be seen from the above that no matter whether the water storage pot 10 is filled with water, when the water storage pot 10 is placed on the water supply mechanism 20, the water supply mechanism 20 can automatically determine whether to supply water to the water storage pot 10, and It is very convenient to ensure that the water storage jug 10 is in a water-filled state when the user takes it next time. In addition, the water storage pot 10 and the water supply mechanism 20 are in a common environment. For example, the water storage pot 10 and the water supply mechanism 20 are both located in the refrigerator 300 , so cold water can be provided at any time.

After the water storage pot 10 is fixed on the fixed structure 21, if the sensor does not detect the induction element, or the sensor detects that the change in the magnetic field strength is 0, it means that the water storage pot 10 is not in the correct position , the execution command is to close the water valve 222, so water can be avoided from falling outside the water storage jug 10, reducing waste.

When the water storage jug 10 is filled with water, the induction element is located at the top of the water storage jug 10 and its position does not change, so the variation of the magnetic field generated by the induction element detected by the sensor is zero. , the execution command is to close the water valve 222 . Further, when the sensing element fails, the execution command is to close the water valve 222 . For example, if the sensing element is fixed in the water storage jug 10 and cannot move along the height direction of the water storage jug 10 as the water level changes, the execution command is to close the water valve 222 . For another example, when the sensing element is fixed on the bottom of the water storage jug 10 instead of the top, the execution command is to close the water valve 222 . Fault detection is performed by supplying water to the water storage jug 10 in a short period of time. The water supply during this period should be optimized according to the water supply speed and the size of the water storage jug 10, so that the water supply during this period of time is almost negligible, so as not to waste water .

The induction unit includes a first induction unit for judging whether the water storage pot 10 is fixed at the correct position of the water supply mechanism 20, a second induction unit for judging the water level in the water storage pot 10; The sensing element is the same sensing element as the second sensing element. The sensor includes a first sensor for detecting the first sensor element, a second sensor for detecting the variation of the second sensor element; the first sensor and the second sensor are the same sensor.

To sum up, in the water supply device 100 of the present utility model, no matter whether the water storage pot 10 is filled with water, when the water storage pot 10 is placed on the water supply mechanism 20, the water supply mechanism 20 can automatically judge whether it is full of water or not. It is very convenient to supply water to the water storage jug 10 and ensure that the water storage jug 10 is filled with water when the user takes it next time. In addition, the water storage jug 10 and the water supply mechanism 20 are in a common environment, so that required liquid beverages can be provided in time.
