The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
An embodiment of the present invention provides a water storage device, which may be applied to a refrigeration device, and more particularly, to a refrigerator, that is, the embodiment also provides a refrigeration device and a refrigerator having the water storage device, but is not limited thereto.
Specifically, the water storage device comprises a water container 1, a floating part 2 and a magnetic sensor 3, wherein the floating part 2 floats on the water surface in the water container 1, the floating part 2 comprises a magnet 22, and the magnetic sensor 3 is used for detecting the magnetic field intensity of the magnet 22 and judging the water level according to the intensity of the magnetic field. The technical solution of the present invention is described below with reference to two specific embodiments of the water storage device shown in the drawings, the protection scope of the present invention is not limited thereto, and the improvements mentioned in the embodiments can be applied to other water storage devices.
Example 1
The floating part 2 of the embodiment further comprises a float 21, the float 21 is connected with a magnet 22 and floats on the water surface together with the magnet 22, the magnetic sensor 3 is arranged below the water container 1, and as shown in figure 1 or figure 2, when the floating part 2 in the water container 1 rises and falls along with the change of the liquid level, the corresponding magnet 22 rises and falls in the water container 1.
To clearly express the position and direction described in the present embodiment, the gravity direction is defined as lower, whereas the gravity direction is defined as upper, the liquid level lifting direction is defined as upper and lower directions, and correspondingly, the floating part 2 also moves up and down synchronously with the up and down movement of the water.
The magnet 22 and the floater 21 can be connected together in a bonding, clamping and other modes, the magnet 22 can also be arranged inside the floater 21, the floater 21 drives the magnet 22 to move up and down, after the floater 21 and the magnet 22 are connected together, the weight of the water discharged on the water surface is always larger than the total weight of the floater 21 and the magnet 22, namely the buoyancy force borne by the floating part 2 is larger than the self gravity, and the floating part 2 always floats on the water surface.
The water container 1 is made of glass or plastic material or other non-ferromagnetic material, and other ferromagnetic material does not exist between the magnetic sensor 3 and the magnet 22, so that the detection of the magnetic field of the magnet by the magnetic sensor 3 is prevented from being influenced.
The magnetic sensor 3 is disposed below the water container 1 so that the relationship of change between the magnet 22 in the float 2 and the magnetic sensor 3 is only close or far, for example, when the water level is lowered, the float 2 moves downward, the distance between the magnet 22 and the magnetic sensor 3 becomes close, the magnetic field intensity detected by the magnetic sensor 3 increases, and it can be judged that the water level is lowered; when the water level rises, the floating part 2 moves upward, the distance between the magnet 22 and the magnetic sensor 3 becomes longer, and the magnetic field intensity detected by the magnetic sensor 3 is weakened, so that it can be judged that the water level is high, and thus the requirement for the processor is not high, the control is sensitive, and the cost is reduced. And set up like this and only need use a magnetic sensor 3, can judge the change of height of water level, practiced thrift the cost, especially more have the advantage in the aspect that only needs detect the minimum value of water level, when magnetic field intensity is greater than a definite value, can judge that the water level crosses lowly and can inform the user in time add water, avoided the user to forget the problem of adding water.
The common liquid level height detection device needs to extend into the water container 1, so that the water container 1 is difficult to take out, the water adding process is inconvenient, some non-contact detection devices, such as ultrasonic detection devices, have higher cost and large power consumption, but the magnetic sensor 3 and the water container 1 can be in a non-contact mode, the water container 1 is easy to take out, the adopted detection mode has low cost and low power consumption, the effect is more obvious when only the lowest water level needs to be detected, the detection precision of the lowest water level is high, and the control method is simple and reliable.
Further, the water storage device comprises a limiting part 4 arranged inside the water container 1, the limiting part 4 limits the floating part 2 to move vertically along the direction vertical to the liquid level, namely, the floating part 2 is limited to move in the plane vertical to the up-down direction, the floating part 2 only moves along the direction vertical to the up-down straight line, thus, the magnetic sensor 3 is arranged at the bottom of the floating part 2, namely, the stable magnetic field strength value of the magnet 22 at different liquid levels can be detected, the limiting part 4 is vertically arranged along the direction vertical to the liquid level, the limiting part 4 can be continuous or discontinuous, the weak limiting part 4 is continuous, the extending direction of the limiting part 4 is the up-down direction, if the limiting part 4 is provided with a plurality of discontinuous limiting units, the arrangement direction of the plurality of limiting units is the up-down direction, so that any position of the floating part 2 in the water container 1 can be lifted along with the water level, with only an upward or downward tendency to move.
Furthermore, the limiting part 4 comprises a plurality of limiting rods 41, the end parts of the limiting rods 41 are fixed on the bottom wall of the water container 1 and extend in the direction perpendicular to the liquid level, the floating part 2 is arranged among the limiting rods 41, in the embodiment, 4 limiting rods 41 are arranged, the floating part 2 is arranged among the 4 limiting rods 41, and the floating part 2 can also be arranged in other quantities, so that the contact area between each limiting rod 41 and the floating part 2 is approximately equal, the stress of the floating part 2 is uniform and is not easy to be clamped, if one side is limited by the side wall of the water container 1, one side is limited by the limiting rods 41, the limiting modes of different positions are inconsistent, and the clamping possibility is high; on the other hand, the contact surface between the limiting rod 41 and the floating part 2 is very small, even the line contact is carried out, the contact area between the floating part 2 and the limiting part 4 is reduced, the friction and the probability of being stuck are reduced, and the movement of the floating part 2 is smoother.
Set up the cell body on the float 21, the cell body cooperatees with gag lever post 41, as shown in fig. 3, when flotation segment 2 sets up between many gag lever posts 41, there are a plurality of gag lever posts 41 and set up at float 21 the cell body position for the in-process of flotation segment 2 up-and-down motion, flotation segment 2 can not produce the problem of turning on one's side like this, the up-and-down motion of parallel ground all the time. The sides of being connected between float 21 and the gag lever post 41 all set up the fillet for float 21 can not block on gag lever post 41, and is level and smooth when float 21's the motion, and gag lever post 41 can set up to round rod or the square pole that sets up the fillet with one side that float 21 is adjacent. In addition, a structure and a material with the lowest friction coefficient are selected between the limiting rod 41 and the floater 21, for example, the surfaces of the floater 21 and the limiting rod 41 are smooth as much as possible.
