The water storage device for the water purifier with the structure can enable water in the tank to be less when the liquid level detection device displays that the water in the tank is in a low water level state. Thereby the water in the box is discharged to the greatest extent, and the situation that residual water is stored in the box for a long time to cause bacteria breeding in the water storage device and influence the use experience of a user is avoided. And because the bottom surface of the box body is additionally provided with the sunken part, the effective volume of the box body is further increased, and more water can be stored into the box body.

Illustratively, the follower component is a float; the liquid level detection device further includes: the floater support is arranged in the box body, extends in the vertical direction and can move along the floater support; and a detector for detecting the vertical position of the float within the tank.

Illustratively, the float seat extends into the recess a length greater than or equal to half of the height of the float.

The float support with the structure can enable the float to sink into the concave part, and enable the float to move to the position where the center of the float and the bottom surface of the box body are on the same horizontal plane or even lower. Therefore, when the liquid level detection device sends a low water level signal, the water in the box body can be basically discharged, and the residual water in the box body is reduced.

Illustratively, the recess has a first recess sidewall, the tank has a first tank sidewall, the first recess sidewall is coplanar and connected with the first tank sidewall, and the float support abuts the first recess sidewall and the first tank sidewall.

This is on the one hand to facilitate the fixing of the float support. On the other hand, in the embodiment of the liquid level detection device using the visible liquid level situation in the tank body, the liquid level situation is convenient to observe.

Exemplarily, an installation clamping groove is formed in the inner side wall of the box body, the installation clamping groove penetrates through the first box body side wall and the first concave portion side wall along the vertical direction, an installation protrusion is arranged on the outer side wall of the float support, and the installation protrusion is connected to the installation clamping groove.

The structure can facilitate the installation and the disassembly of the float support and the box body, and is simple in structure and easy to realize.

Illustratively, the detector is a proximity switch disposed outside the housing.

Illustratively, the proximity switch is disposed on a sidewall of the recess.

Since the level of the proximity switch provided on the side wall of the depression is lower than the level of the proximity switch provided on the bottom surface of the tank, it is possible to detect a lower water level, not only to make the water remaining in the tank less, but also to make the water remaining in the depression less.

Exemplarily, the water storage device for the water purifier is provided with a water outlet which is communicated with the inside of the concave part. The liquid level detection device has the function of discharging water in the box body as much as possible, so that the lowest water level detected by the liquid level detection device is lower than the bottom surface of the box body. The residual water in the box body is reduced.

Illustratively, the water outlet is disposed on a sidewall of the recess or a bottom surface of the recess.

Thus, water can be discharged through the water outlet under the condition that the water in the box body is not pumped out by the water suction pump, and the water level of the box body can be lowered to be lower than the bottom surface of the box body. When the liquid level detection device sends a low water level signal, water in the box body can be discharged as much as possible, and the residual water amount in the box body is reduced.

Illustratively, the bottom surface of the recess is inclined to form a low position and a high position, and the water outlet is arranged at the low position.

Therefore, with the water outlet at the position, when water is discharged from the concave part, the water in the concave part can be discharged as much as possible, the lowest water level in the box body can be lower than the bottom surface of the box body, and the residual water in the concave part can be reduced.

Illustratively, the projection area of the concave part on the plane of the bottom surface of the box body is smaller than the area of the bottom surface of the box body.

Thus, the volume of the concave part can be reduced, and the situation that more water is reserved in the concave part after the water is discharged from the box body is avoided. The use of more material due to the provision of the recess can also be reduced. The cost of the product can be reduced.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

As shown in fig. 1-2, the utility model provides a water storage device for water purifier, which comprises a box body 100 and a liquid level detection device 200. The liquid level detection apparatus 200 can detect the water level in the tank 100 and transmit the sensed information or the electric signal to the user. The liquid level detection device 200 may be a float level gauge, a magnetic flip plate level gauge, or the like, which will be described in detail below.

The case 100 is provided with a recess 300 recessed downward from the bottom surface of the case 100. The recess 300 forms a water storage space under the bottom surface of the case 100 to communicate with the case 100. The recess 300 may be located anywhere on the bottom surface of the case 100, such as in the center or near the side walls. Wherein the bottom surface of the case 100 does not include the bottom surface of the recess 300. That is, the bottom surface of the case 100 is a plane higher than the bottom surface of the recess 300.

The liquid level detection apparatus 200 includes a follower member disposed in the tank 100, the follower member being movable according to a change in a water level in the tank 100. Generally, the follower member has a density lower than that of the liquid contained in the tank 100, so that the follower member floats on the surface of the liquid and moves vertically in accordance with the change of the liquid level. The following component can be a floater or a magnetic floating block in the magnetic turning plate liquid level meter. Wherein at least a part of the moving range of the follower member is within the recess 300, in other words, when the water level drops into the recess 300, the follower member may enter into the recess 300.

The float level gauge may include a floating float level gauge and a magnetostrictive float level gauge.

In the float level gauge, the float can be connected with a guide rod extending out of the tank body 100, and the guide rod can vertically move along with the float to display the change of the water level in the tank body 100 outside the tank body 100; or by the lever principle, one end of the lever is connected with the floating ball floater, and the other end of the lever moves reversely along with the vertical movement of the floater. The foregoing illustrates only some of the embodiments and is not intended to represent all of the structures. Through the floating ball float level gauge with various structures, the detection of the water level inside the box body 100 can be realized. If a sensor is arranged on the float level gauge, water level information in the tank body 100 can be sent out in an electric signal mode for a user to take.

The magnetostrictive float liquid level meter comprises a waveguide tube and a magnetic float sleeved on the waveguide tube. The waveguide tube is vertically inserted into the box body 100, and the magnetic floater can move up and down along the waveguide tube along with the change of the liquid level. A permanent magnetic ring is arranged in the magnetic float. When the magnetostrictive float liquid level meter works, the circuit part of the sensor excites pulse current on the guided wave guide pipe, and the pulse current magnetic field is generated around the guided wave guide pipe when the current propagates along the guided wave guide pipe. When the pulse current magnetic field meets the magnetic ring magnetic field generated by the magnetic float, the magnetic field around the magnetic float changes, so that the wave guide tube made of magnetostrictive material generates a torsional wave pulse at the position where the magnetic float is located, and the pulse is transmitted back along the wave guide tube at a fixed speed and is detected by the detector. The position of the magnetic float, namely the position of the liquid level can be accurately determined by measuring the time difference between the pulse current and the torsional wave.

The magnetic turning plate liquid level meter can comprise a body, a plurality of magnetic turning columns, a magnetic floating block and a flange cover. The body can be the pipeline that is equipped with the magnetic levitation piece, and the magnetism turns over the post and sets up in the body outside and hug closely the body along vertical direction, through the blind flange, is connected body and box 100, forms the linker, and the water level change in the box 100 will also embody in this body in step. For convenient observation, the front and back surfaces of the magnetic turning column are provided with two colors. When the liquid level in the measured container rises and falls, the magnetic floating block in the body also rises and falls along with the liquid level. In the rising process of the magnetic block, the permanent magnetic steel in the magnetic block transmits the magnetic field to the magnetic turning column through magnetic coupling, and the magnetic turning column close to the magnetic block is turned over by 180 degrees. The front and back surfaces of the magnetic turning column can have different colors, and after the magnetic turning column is turned, the color displayed on the outer side of the magnetic turning column is changed. When the liquid level descends, the magnetic floating block is close to the magnetic turning column which is turned over before again, and the magnetic turning column is turned over. The juncture of the front color and the back color of the magnetic turning column is the actual height of the liquid level in the box body 100, so that clear indication of the liquid level is realized.

Generally, a water outlet is provided in a water storage device for a water purifier to discharge water inside the tank 100. Illustratively, the water outlet may be provided on the tank 100, such as a side wall of the tank 100 or a bottom surface of the tank 100. In another embodiment, the water outlet may be disposed on a water outlet pipe extending into the tank 100, the water outlet pipe is inserted into the tank 100, and water in the tank 100 is pumped out through the water outlet pipe by a water pump. Of course, in the embodiment where the water outlet is directly disposed on the tank 100, the water in the tank 100 may be pumped out by a water pump.

The liquid level detection device 200 is used for prompting a user that water in the tank 100 is at a low level and is not enough to be drained continuously, and water needs to be stored in the tank 100; in the water storage device for the water purifier connected with the water suction pump, when the liquid level detection device 200 detects that the water level in the tank 100 is already at the low water level, the water suction pump can be turned off, and the water suction pump is prevented from idling.

Because the following components are all devices which have a certain height and can float above the liquid level, in the existing water storage device, when the water level drops to be close to the bottom surface of the box body 100, even if the following components touch the bottom surface of the box body 100, namely, the following components are already at the lowest height of the following components in the box body 100, and the current water level in the box body 100 is displayed, water with a certain height still remains in the box body 100.

The recess 300 is formed in the bottom surface of the case 100, so that even when the water level in the case 100 is lowered to the same height as the bottom surface of the case 100 or even lower than the bottom surface of the case 100, the follower is not stopped by the bottom surface of the case 100 and enters the recess 300. At this time, the water level in the tank 100 is already lower than the bottom surface of the tank 100. The follower member is located in the recess 300, which indicates that the water in the tank 100 is in a low water level state.

The water storage device for the water purifier having such a structure can allow less water to remain in the tank 100 when the liquid level detection device 200 indicates that the water in the tank 100 is already in a low water level state. Thereby as much as possible with the water clean of box 100 in, avoided having preserved residual water for a long time in the box 100, cause breeding the bacterium in the water storage device, influence user's use and experience. In addition, since the recess 300 is additionally formed on the bottom surface of the tank 100, the effective volume of the tank 100 is further increased, and more water can be stored in the tank 100.

Illustratively, the follower component may be a float 210, wherein the liquid level detection device 200 may further comprise a float seat 220 and a detector 230. The float support 220 is provided in the tank 100, the float support 220 extends in a vertical direction, and the float 210 can move along the float support 220. The float support 220 may be a guide rod, and the float 210 is sleeved on the guide rod; the float support 220 may also be a cradle capable of housing the float 210, within which the float 210 is free to move. The float support 220 may be constructed in various manners as long as the float 210 can be moved along the float support 220. The detector 230 may be used to detect the vertical position of the float 210 within the tank 100. Here, the detector 230 may be a magnetic flip board as described above, which may be connected to a component that transmits an electrical signal. The detector 230 may be a proximity switch or a hall switch. The detector 230 may be any device that can send an electrical signal when the float 210 moves.

Therefore, the liquid level detection device with the structure can transmit the water level in the box body 100 through the electric signal, so that the water storage device for the water purifier has the capacity of automatically sending the water level signal, and the automation degree is improved.

Since the float 210 moves within the range provided by the float mount 220, the range of movement cannot exceed the length of the float mount 220. Illustratively, the float mount 220 may extend into the recess 300 with a length greater than or equal to half the height of the float 210 within the recess 300, as shown in fig. 2-3. It has been mentioned above that the floats 210 are all of a certain height, and typically the components in which the detector 230 can be triggered are all located at half the height of the float 210, i.e. in the centre of the float 210.

In designing the float 210, the density of the float 210 is adjusted so that the center of the float 210 is level with the liquid surface when it floats on the liquid surface. For example, in the embodiment of the magnetic turn-over plate liquid level meter, the magnetic floating block is arranged at the center of the magnetic floater, and the magnetic turn-over plate can turn over only if the center of the magnetic floater is close to the magnetic turn-over plate. The magnetic float in the magnetostrictive float liquid level meter has the same reason.

However, when the center of the float 210 is at the same level as the bottom surface of the tank 100, the lower half of the float 210 has actually entered the recess 300, and in order not to make the float 210 touch the bottom surface of the recess 300 to minimize the amount of water in the tank 100 when the float 210 is at the lowest position, the depth of the recess 300 may be greater than or equal to half the height of the float 210 to receive the portion of the float 210 entering the recess 300. Further, the float support 220 also needs to extend into the recess 300, and the length in the recess 300 is greater than or equal to half of the height of the float 210, so that the center of the float 210 can be at the same level with the bottom surface of the tank 100 or lower than the bottom surface of the tank 100 after the float 210 sinks into the recess 300.

In summary, the float holder 220 having the above structure can sink the float 210 into the recess 300, and can move the float 210 to a position where the center of the float 210 is at the same level as the bottom surface of the tank 100 or even lower. Thus, when the liquid level detection device 200 sends a low level signal, the water in the tank 100 can be substantially drained, and the residual water in the tank 100 can be reduced.

Illustratively, the projection area of the recess 300 on the plane of the bottom surface of the case 100 is smaller than the area of the bottom surface of the case 100. In the above embodiment, the projected area of the recess 300 may be such that it can only receive the float seat 220 protruding into the recess 300.

Thus, the volume of the recess 300 can be reduced, and it is possible to prevent a large amount of water from being stored in the recess 300 after the water is discharged from the tank 100. The use of more material due to the provision of the recess 300 can also be reduced. The cost of the product can be reduced.

Illustratively, referring to FIGS. 1-2, the recess 300 has a first recess sidewall 310 and the case 100 has a first case sidewall 110. The first recess sidewall 310 is coplanar with and connected to the first case sidewall 110. Thus, the recess 300 may be regarded as a space formed by extending the sidewall of the case 100 downward. This is advantageous in that the float support 220 can be mounted on the side wall of the tank 100. In one embodiment, the float support 220 may be mounted adjacent to the first recess sidewall 310 and the first casing sidewall 110, a vertical groove may be formed in the first casing sidewall 110 and the first recess sidewall 310, and a transparent member may cover the groove, so that a user can directly observe the position state of the float 210 on the float support 220 through the groove. In another embodiment, the magnetic flip plate level gauge described above is more suitable for use with the tank 100 of this configuration.

Thus, on the one hand, the fixation of the float support 220 is facilitated. On the other hand, in the embodiment using the liquid level detection device that can visually detect the condition of the water level in the tank 100, it is convenient to observe the condition of the liquid level.

Further, as shown in fig. 4, the inner sidewall of the case 100 is provided with the mounting slot 120, and the inner sidewall may include a sidewall of the first case sidewall 110 inside the case and a sidewall of the first recess sidewall 310 inside the recess. The mounting slot 120 penetrates the first case side wall 110 and the first recess side wall 310 in a vertical direction. The outer side wall of the float support 220 is provided with a mounting protrusion 221, and the float support 220 can be inserted into the mounting groove 120 through the mounting protrusion 221, so that the connection between the float support 220 and the box 100 is realized. When the float support 220 is removed, the float support 220 may be moved upward along the mounting slot 120, such that the float support 220 is withdrawn from the mounting slot 120.

The structure can facilitate the installation and the disassembly of the float support 220 and the box body 100, and has simple structure and easy realization.

Illustratively, the detector 230 is a proximity switch disposed outside the case 100. The proximity switch may transmit an electrical signal by magnetic induction or hall induction, which depends on the material and operating characteristics of the float 210. The float 210 may move up and down in a float seat 220 inside the tank 100. When it moves into proximity with the proximity switch, the proximity switch will be triggered causing the proximity switch to send an electrical signal.

Because the detector 230 mostly needs to be connected through parts such as a wire, the proximity switch is selected and arranged outside the box body 100, so that the contact between the detector 230 and water in the box body 100 can be effectively avoided, the safety is improved, and the risk of damage to the detector 230 is also avoided.

In order to be able to detect the lowest water level of the tank 100, a proximity switch may be provided on the bottom surface of the tank 100, which is triggered when the float 210 approaches the bottom surface of the tank 100. Preferably, the proximity switch may be disposed on a sidewall of the recess 300, such as the aforementioned first recess sidewall 310. Since the level of the proximity switch provided on the sidewall of the recess 300 is lower than that of the proximity switch provided on the bottom surface of the tank 100, it is possible to detect a lower water level, not only to make less water remain in the tank 100, but also to make less water remain in the recess 300.

Exemplarily, referring to fig. 1-3, the water storage device for the water purifier has a water outlet 400, and the water outlet 400 is communicated with the recess 300. The water outlet 400 may be provided on a water pipe inserted into the recess 300, and the water in the case 100 is pumped out by a suction pump. The water outlet 400 may be provided in the recess 300. The function of the device is to drain as much water as possible from the tank 100, so that the lowest water level that can be detected by the liquid level detection device is lower than the bottom surface of the tank 100. Reducing the amount of residual water in the tank 100.

For example, in an embodiment in which the water outlet 400 is provided on the recess 300, the water outlet 400 may be provided on a sidewall of the recess 300 or a bottom surface of the recess 300.

Thus, even when water in the tank 100 is not pumped out by the suction pump, the water can be discharged through the water outlet 400, and the water level in the tank 100 can be lowered to below the bottom surface of the tank 100. When the liquid level detection device 200 sends a low level signal, the water in the tank 100 can be drained as much as possible, reducing the amount of residual water in the tank 100.

Further, the bottom surface of the recess 300 is inclined to form a low and a high in the space where the recess 300 is located. The water outlet 400 may be disposed at a lower portion of the recess 300 so that water in the recess 300 may be discharged relatively cleanly. The water outlet 400 may be provided on the bottom surface of the recess 300 or the sidewall of the recess 300. When the water outlet 400 is provided at the bottom surface of the recess 300, the water outlet 400 may be at the lowest of the bottom surface of the recess 300. When the water outlet 400 is provided on the sidewall of the recess 300, the water outlet 400 may be the lowest of the sides of the recess 300, as shown in fig. 4. That is, the bottom surface of the recess 300 may be inclined downward toward the water outlet 400. In an embodiment in which the water outlet 400 is provided on the sidewall of the recess 300, preferably, the minimum distance H of the water outlet 400 from the bottom surface of the recess 300 may be less than or equal to 10 mm.

It can be seen that, with the water outlet 400 at the above position, when water is discharged from the recess 300, the water in the recess 300 can be discharged as much as possible, and not only the lowest water level in the tank 100 can be made lower than the bottom surface of the tank 100, but also the residual water in the recess 300 can be reduced.

According to another aspect of the present invention, there is provided a water purifier, comprising any one of the water storage devices for water purifier as described above.

For example, in the water purifier, one or more of electromagnetic valves, check valves, high-pressure switches, pumps and the like may be further disposed outside the tank 100. And one or more of the above devices may be disposed in a space formed between the bottom surface of the case 100 and the side wall of the recess 300.

Therefore, the space formed by the lower part of the box body 100 can be reasonably utilized, the size of the water purifier is reduced, and the integration level of the water purifier is improved.
