The inner container of the water dispenser can be a refrigerating inner container capable of preparing cold water, and can also be a heating inner container for preparing hot water. The inner container of the water dispenser effectively reduces the condition that the water supplementing driver is closed when the inner container body of the inner container of the water dispenser is not filled with water, so that the water supplementing is stopped, the inner container body can be filled with water every time of water supplementing, the utilization rate of the inner container of the water dispenser is greatly improved, and the yield of cold water or hot water prepared at one time is increased.

Referring to fig. 1 and 2, in an embodiment of the liner of the water dispenser of the present invention, the liner 10 of the water dispenser includes a liner body 100 and a liquid level device 200. The top wall of the liner body 100 is provided with an exhaust hole 13, and the exhaust hole 13 is suitable for being communicated with the atmospheric environment. The liquid level device 200 is arranged outside the inner container body 100; the liquid level apparatus 200 comprises a liquid storage box 210 and a detector 220; wherein, the liquid storage box 210 is communicated with the inner container body 100; the detector 220 is disposed in the liquid storage box 210, and the position of the detector 220 in the liquid storage box 210 is higher than or equal to the top wall of the liner body 100.

Specifically, the heat exchanger 110 is disposed inside the liner body 100, and the heat exchanger 110 is adapted to exchange heat with water in the liner body 100 to obtain cold water with a low temperature and store the cold water in the liner body 100, so that the cold water prepared by the liner body 100 can be used at any time when a user needs the cold water. The cold water and the normal-temperature water are relative, and the temperature of the cold water after heat exchange is lower than that of the normal-temperature water. The top of the inner container body 100 is provided with a water inlet 11, so that the inner container body 100 can replenish water from the top thereof. The liner body 100 is further provided with a water outlet 12 communicated with the water outlet end 50 of the water dispenser liner 10, and the water outlet 12 can be arranged at the bottom or the side of the liner body 100. Here, in order to prevent the newly supplemented normal temperature water from being mixed with the prepared cold water, the water outlet 12 is provided at the bottom of the inner container body 100, which will be described in detail later.

Referring to fig. 1 to 3, when the liner 10 of the water dispenser is installed in the water dispenser, the water inlet 11 of the liner body 100 needs to be communicated with the water supply source 40 through the water supplement driver 21, the water outlet 12 of the liner body 100 is communicated with the water outlet 50, and the controller of the water dispenser is connected with the detector 220 and the water supplement driver 2 in the liquid level device 200 of the liner 10 of the water dispenser, so that the controller can control the on-off of the water supplement driver 21 according to the water full signal fed back by the detector 220. See, in particular, the detailed description below.

When water is replenished to the inner container 10 of the water dispenser, water is input into the inner container body 100 from the water inlet 11 of the inner container body 100, the water storage capacity in the inner container body 100 is increased, and the water level in the inner container body 100 is gradually increased, so that the air in the inner container body 100 is upwards extruded, and the air in the inner container body 100 is discharged from the exhaust hole 13 at the top of the inner container body 100. When the liquid level in the liner of the liner body 100 rises to a position communicated with the liquid storage box 210, the water in the liner body 100 also enters the liquid storage box 210 of the liquid level device 200.

Because the liquid level device 200 is located outside the liner body 100, and the position of the detector 220 of the liquid level device 200 in the liquid storage box 210 is higher than or equal to the top wall of the liner body 100, before the liquid level of the liner body 100 reaches the top wall of the liner body 100, the liquid level in the liquid storage box 210 cannot reach the position flush with the top wall of the liner body 100, so that the detector 220 of the liquid level device 200 cannot sense the water level, and therefore, a water full signal cannot be fed back to the controller, and the controller cannot control the water supplement driver 22 to be closed under the condition that the liner body 100 is not filled up. Until the water level of the inner container body 100 reaches the top wall of the inner container body 100, the water level in the liquid storage box 210 reaches or is higher than the position flush with the top wall of the inner container body 100, at this time, the detector 220 of the liquid level device 200 can sense the water level, so as to feed back a water full signal to the controller, and then the controller controls the water supplement driver 22 to close according to the water full signal.

As for the type of the detector, the detector may be a water level floating ball or a water level probe, which may be specifically selected according to actual needs, and is not specifically limited herein. Optionally, in this embodiment, the detector is a water level float ball.

According to the technical scheme, the liquid level device 200 is arranged on the outer side of the liner body 100 of the water dispenser liner 10, and the position of the detector 220 of the liquid level device 200 in the liquid storage box 210 is higher than or equal to the top wall of the liner body 100, so that when the water replenishing mode of the water dispenser liner 10 is used, the liquid level in the liquid storage box 210 of the liquid level device 200 can reach or be higher than the position flush with the top wall of the liner body 100 only after the water level of the liner body 100 reaches the top wall of the liner body 100, namely the liner body 100 is full of water, at the moment, the detector 220 of the liquid level device 200 can sense the liquid level, so that a water full signal is fed back to the controller, and the controller controls the water replenishing driver 22 to be closed. Therefore, the situation that the water supplementing driver 22 is closed when the liner body 100 of the water dispenser liner 10 is not filled with water to stop water supplementing can be effectively reduced, the liner body 100 can be filled with water every time of water supplementing, the utilization rate of the volume of the water dispenser liner 10 is greatly improved, and the yield of cold water or hot water prepared at one time is increased.

Referring to fig. 1 and 2, in one embodiment, considering that the detector 220 of the liquid level apparatus 200 is installed in the liquid storage box 210, if the detector 220 is located at a position higher than or equal to the top wall of the liner body 100 in the liquid storage box 210, it is required that the liquid storage box 210 is located at a position higher than the liner body 100. However, the position of the liquid storage box 210 is not as high as possible, because, if the liquid storage box 210 is too high, for example, the whole liquid storage box 210 is higher than the top wall of the inner container body 100, then after the inner container body 100 is filled, the water in the inner container body 100 can be forced to be squeezed into the liquid storage box 210 by applying larger pressure to the water in the inner container body 100, so that the detector 220 is not favorable for sensing a water level signal in time, and further the situation that the water supplement driver 22 is not closed in time may occur.

In view of the above, in order to solve the above problem, optionally, the liquid storage box 210 hasHaving a bottom wall and a top wall; wherein, the bottom wall of the liquid storage box 210 is located at a position lower than the top surface of the liner body 100; the top wall of the liquid storage box 210 is located at a position higher than the top wall of the liner body 100. H in FIG. 2₁Expressed as a height difference between the position where the bottom wall of the reservoir 210 is located and the top surface of the liner body 100; h is₂Indicated as the height difference between the position of the top wall of the reservoir 210 and the top surface of the liner body 100. Then there should be h₁> 0, and h₂Is greater than 0. Therefore, the upper part of the liquid storage box 210 is slightly higher than the top wall of the inner container body 100, and the lower part of the liquid storage box 210 is slightly lower than the top wall of the inner container body 100, so that the detector 220 in the liquid storage box 210 is arranged on the top wall of the inner container body 100, and the liquid storage box 210 is not too high.

Referring to fig. 1 and 2, in an embodiment, in order to facilitate the communication between the liquid storage box 210 and the liner body 100, a liquid storage inlet 211 is formed in a bottom wall of the liquid storage box 210; the side wall of the inner container body 100 is provided with a water passing port 14, and the water passing port 14 is communicated with the liquid storage inlet 211. Specifically, the water passing opening 14 is disposed on a position of a side wall of the liner body 100 near a top edge thereof, and the water passing opening 14 is lower than the liquid storage inlet 211 of the liquid storage box 210, so that water in the liner body 100 can flow into the liquid storage box 210. As for the way of communicating the water passing port 14 with the liquid storage inlet 211, there may be various designs.

Specifically, the liquid level device 200 further includes a water conduit 230, one end of the water conduit 230 is connected to the liquid storage inlet 211, and the other end of the water conduit 230 is connected to the water drainage port 14. The water guide pipe 230 may be made of a common hose material. When the device is installed, two ends of the water conduit 230 are respectively inserted into the water outlet 14 and the liquid storage inlet 211. Of course, the water introduction duct 230 is not necessarily required. In other embodiments, the liquid storage box 210 may be directly attached and fixed to the top of the liner body 100, so that the liquid storage inlet 211 of the liquid storage box 210 is directly in butt joint with the water outlet 14 of the liner body 100, and the liquid storage box 210 and the liner body 100 may also be communicated with each other, and the connection position is sealed to prevent water leakage.

It is also considered that if the position of the water conduit 230 is too high, the water in the inner container body 100 may not pass through the water conduit 230, and the liquid level device 200 may fail. Therefore, in the present embodiment, in order to reduce the occurrence of such a situation, the position of the water conduit 230 is set to be lower than the top wall of the liner body 100, so that after the liner body 100 is filled with water, the water conduit 230 can smoothly enter the water conduit 230, and then the water conduit 230 passes through the water conduit 230 and enters the liquid storage box 210, so as to be sensed by the detector 220 in the liquid storage box 210.

Referring to fig. 1 and 2, in an embodiment, it is considered that the liquid storage box 210 of the liquid level apparatus 200 needs to be communicated with the atmosphere to enable water in the liner body 100 to smoothly enter and exit the liquid storage box 210. To this end, the reservoir 210 may be designed to be open or vented 212. If the design is uncovered on stock solution box 210, then stock solution box 210 exposes area at atmospheric environment can be great, and atmospheric environment's air can carry microorganisms such as dust or bacterium to get into stock solution box 210, and then scurries into inner bag body 100 from stock solution box 210, leads to inner bag body 100 also to receive the pollution.

Based on this, an exhaust outlet 212 may be designed on the top of the liquid storage box 210, and the exhaust outlet 212 is communicated with the exhaust pipe 70 to communicate with the atmosphere through the exhaust pipe 70. So, prolonged the route of stock solution box 210 with the atmospheric environment intercommunication, in the difficult follow blast pipe 70 of dust etc. that the atmospheric environment carried enters into stock solution box 210 to guarantee that stock solution box 210 has higher leakproofness and cleanliness.

Further, the exhaust outlet 212 is located at a position higher than the top wall of the liner body 100 to reduce overflow of the liquid storage box 210 and discharge of the liquid from the exhaust outlet 212. Please refer to fig. 2, h in fig. 2₃Expressed as a height difference, h, between the position where the exhaust outlet 212 is located and the top wall of the liner body 100₃＞0。h₃Can be reacted with h₂In which said exhaust outlet 212 is arrangedThe top wall of the liquid storage box 210; h is₃May also be less than or equal to h₂Namely, the exhaust outlet 212 is provided on the sidewall of the reservoir 210. In particular, the exhaust outlet 212 is disposed on a side wall of the reservoir 210 and is also close to a top edge of the side wall, so that the exhaust outlet 212 is at a high position, and the reservoir 210 is not easy to overflow.

Further, the liquid level device 200 further comprises a bypass air pipe 240, one end of the bypass air pipe 240 is connected with the exhaust outlet 212 of the liquid storage box 210, and the other end of the bypass air pipe 240 is connected with the exhaust pipe 70 of the atmospheric environment or the water dispenser. That is, the end of the bypass air pipe 240 away from the reservoir 210 can be directly connected to the atmosphere; alternatively, in the case of the water dispenser having the exhaust pipe 70, the bypass air pipe 240 may be connected to the exhaust pipe 70 so as to communicate with the atmosphere through the exhaust pipe 70, thereby reducing the piping design.

Specifically, the bypass air pipe 240 may be made of a rubber pipe material. When the exhaust pipe is installed, one end of the bypass air pipe 240 is directly inserted into the exhaust outlet 212, and the other end of the bypass air pipe 240 is inserted into the connection port 71 of the exhaust pipe 70, so that the assembly is simple and the operation is easy. Because the position of the exhaust outlet 212 is higher than the top wall of the liner body 100, the bypass air pipe 240 connected to the exhaust outlet 212 is also at a higher position, which is beneficial to the conduction between the bypass air pipe 240 and the exhaust pipe 70 and the exhaust, and is not easy to cause water blockage.

Of course, the bypass air pipe 240 is not necessary. In other embodiments, the exhaust tube 70 may also extend to the top of the reservoir 210 such that the exhaust tube 70 directly interfaces with the exhaust outlet 212 of the reservoir 210, and thus the communication between the exhaust outlet 212 of the reservoir 210 and the exhaust tube 70 may also be achieved, as will be described in more detail below.

Based on any one of the above embodiments, the top of the refrigeration liner 10 is provided with a water inlet 11, and the bottom of the refrigeration liner 10 is provided with a water outlet 12, so that the refrigeration liner 10 can feed water from the top and discharge water from the bottom, wherein the newly supplemented normal temperature water is located at the upper layer, and cannot be mixed with the cold water at the lower layer immediately, so that the cold water at the lower layer can be output to the water outlet 50. For example, the refrigerated liner 10 has a bottom wall, side walls and a top wall. The water inlet 11 can be positioned on the top wall of the refrigeration liner 10 or on the side wall near the top edge thereof; the water outlet 12 may be located on the bottom wall of the refrigeration liner 10, and is located at a position of the side wall close to the bottom edge thereof.

Specifically, the water inlet 11 is located on the top wall of the refrigeration liner 10, and the water outlet 12 is located on the bottom wall of the refrigeration liner 10. The exhaust holes 13 are formed in the top wall of the refrigeration liner 10, so that air at the top of the refrigeration liner 10 can be completely exhausted, and dead angles of air filling at the tops of the exhaust holes 13 are avoided. In addition, because the newly supplemented normal temperature liquid is located in the upper space of the refrigeration liner 10 and the prepared cold liquid is located in the lower space of the refrigeration liner 10, the prepared cold water is not mixed with the newly supplemented normal temperature water, namely, the cold water is preferentially discharged from the water outlet 12 at the bottom of the refrigeration liner 10, so that the cold water discharged from the water outlet 12 is ensured to keep a low outlet water temperature.

Referring to fig. 1 to 3, the present invention further provides a water dispenser, which includes a water dispenser liner 10, a water replenishing assembly 20 and a controller (not shown in the figures). Wherein, the concrete structure of the liner 10 of the water dispenser refers to the above embodiment; the water supplementing assembly 20 comprises a water supplementing pipe 21 and a water supplementing driver 22, wherein the water supplementing pipe 21 is suitable for communicating the water inlet 11 of the water dispenser liner 10 with the water supply source 40; the water replenishing driver 22 is arranged on the water replenishing pipe 21; the controller is connected with the water supplementing driver 22 and the detector 220 of the liquid level device 200 in the water dispenser liner 10. Since the water dispenser adopts all the technical schemes of all the embodiments, all the beneficial effects brought by the technical schemes of the embodiments are also achieved, and the detailed description is omitted.

Referring to fig. 4, the arrows in solid lines in fig. 4 indicate the water flow direction; the straight dotted arrow indicates the air discharge direction. When the water supplementing mode of the water dispenser is used, the water supplementing driver 22 is started, water of the water supply source 40 is conveyed into the water dispenser liner 10 from the water supplementing pipe 21 under the driving of the water supplementing driver 22, so that the water quantity in the water dispenser liner 10 is increased, the liquid level in the liner body 100 is gradually increased, and air in the liner body 100 is upwards extruded and is discharged from the exhaust hole 13 at the top of the liner body. In this process, along with the rising of liquid level in the inner bag body 100, water in the inner bag body 100 can enter into the liquid storage box 210 of the liquid level device 200 from the position of the inner bag body 100 communicated with the liquid storage box 210 gradually, and the liquid level in the liquid storage box 210 can also rise.

Because the liquid level device 200 is located outside the liner body 100, and the position of the detector 220 of the liquid level device 200 in the liquid storage box 210 is higher than or equal to the top wall of the liner body 100, when the liquid level of the liner body 100 reaches the top wall of the liner body 100, the liquid level in the liquid storage box 210 does not reach the position flush with the top wall of the liner body 100, so that the detector 220 of the liquid level device 200 does not sense the water level, and does not feed back a water full signal to the controller, and the controller does not control the water supplement driver 22 to close under the condition that the liner body 100 is not filled up. Until the water level of the inner container body 100 reaches the top wall of the inner container body 100, the water level in the liquid storage box 210 reaches or is higher than the position flush with the top wall of the inner container body 100, at this time, the detector 220 of the liquid level device 200 can sense the water level, so as to feed back a water full signal to the controller, and then the controller controls the water supplement driver 22 to close according to the water full signal.

In one embodiment, the water supply source 40 may be the water supply tank 40 disposed inside the water dispenser liner 10, or may be a tap water pipe or a water storage tank outside the water dispenser liner 10. The water supply source 40 may be provided by the user or may be a component disposed in the inner container 10 of the water dispenser before the user leaves the water dispenser. Specifically, the water supply source 40 is disposed in the inner container 10 of the water dispenser immediately before the water supply source is delivered.

Further, one end of the water replenishing pipe 21 is connected with the water supply source 40, and the other end of the water replenishing pipe 21 is connected with the water inlet 11 of the refrigeration liner; the water replenishing driver 22 is installed on the water replenishing pipe 21 and used for driving water flow to be input into the refrigeration liner from the water replenishing pipe 21. The water replenishing driver 22 can be selected as a water pump; of course, the refill actuator 22 may be other driving structures that can drive the water to flow. The water supplementing driver 22 and the switch valve 32 are both connected with a controller of the water dispenser, so that the controller controls the on-off of the water supplementing driver 22 and the switch valve 32. After the water dispenser is powered on, the water dispenser can be operated according to a water supplementing mode so as to supplement water to the refrigerating inner container 10.

In an embodiment, due to the existence of the exhaust holes 13 of the liner body 100, air in the atmospheric environment may enter the inner cavity of the liner body 100, and microorganisms such as dust or bacteria may be carried in the air, thereby causing pollution to the liner body 100. In order to solve the problem, optionally, the water dispenser further includes an exhaust pipe 70, one end of the exhaust pipe 70 is connected to the exhaust hole 13 of the liner body 100, and the other end of the exhaust pipe 70 is used for communicating with the atmospheric environment. Due to the existence of the exhaust pipe 70, air in the atmospheric environment firstly enters the exhaust pipe 70, and part of dust, bacteria and other microorganisms are firstly adhered to the inner wall of the exhaust pipe 70 and are not easy to directly fall into the inner cavity of the liner body 100, so that the pollution of the liner body 100 is reduced.

Referring to fig. 5, if the exhaust pipe 70 is kept open without using the water dispenser liner 10, dust, bacteria, microorganisms, or the like in the air of the external environment can easily enter the liner body 100, so that the liner body 100 is easily contaminated. Therefore, in order to isolate the inner container body 100 from the external environment when the water dispenser inner container 10 is not used and keep the inner container body 100 sealed and free from contamination, optionally, the water dispenser further comprises an exhaust valve 80, the exhaust valve 80 is mounted on the exhaust pipe 70, and the exhaust valve 80 is used for controlling the opening or closing of the exhaust pipe 70.

Specifically, in the water replenishing mode or the cold water mode of the water dispenser liner 10, the water outlet valve 32 of the exhaust pipe 70 is opened to communicate the exhaust pipe 70, so that the liner body 100 is communicated with the atmosphere, and water can be smoothly replenished or discharged. When the water dispenser liner 10 is not used, the water outlet valve 32 on the exhaust pipe 70 is closed to block the passage of the exhaust pipe 70, so that the liner body 100 is isolated from the atmospheric environment, and the liner body 100 is kept in a closed environment to prevent the liner body 100 from being polluted. Of course, in other embodiments, the water outlet valve 32 can be directly installed on the exhaust hole 13 without configuring the exhaust pipe 70, so that the piping structure can be greatly reduced, and the cost-saving effect can be achieved.

The exhaust valve 80 may be a solenoid valve to be automatically controlled by a controller. Alternatively, the vent valve 80 may be configured as a manual outlet valve 32 for manual adjustment by the user, considering that the vent valve 80 is generally not required to be opened at a later stage after the initial use of the vent valve 80 for water replenishment. In the present embodiment, the exhaust valve 80 is selected as a solenoid valve.

Alternatively, the exhaust end of the exhaust pipe 70 may be directly connected to the atmosphere, or the exhaust end of the exhaust pipe 70 may be connected to the water outlet end 50 to be connected to the atmosphere through a water outlet hole on the water outlet end 50. In particular, the exhaust end of the exhaust tube 70 is connected to the water outlet end 50. The exhaust valve 80 is normally closed, and the exhaust valve 80 is switched to an open state only when water is replenished to the water dispenser. The specific position at which the exhaust valve 80 is mounted on the exhaust pipe 70 is not particularly limited. Specifically, the exhaust valve 80 may be installed at one end of the exhaust pipe 70 near the exhaust hole 13 to reduce air accumulated in the exhaust pipe 70; of course, the exhaust valve 80 can be installed at the end of the exhaust pipe 70 near the water outlet end 50, or at the middle of the exhaust pipe 70.

Further, the exhaust pipe 70 is provided with a connection port 71; one end of a bypass air pipe 240 of the water dispenser liner 10 is connected with the exhaust outlet 212 of the liquid storage box 210, and the other end of the bypass air pipe 240 is connected with the connecting port 71 of the exhaust pipe 70. The bypass air pipe 240 can be made of common rubber pipe material. When the exhaust pipe is attached, both ends of the bypass air pipe 240 may be inserted into the exhaust outlet 212 and the connection port 71, respectively.

Of course, the bypass air pipe 240 is not necessary. In other embodiments, the exhaust tube 70 may also extend to the top of the liquid storage box 210, such that the connection port 71 of the exhaust tube 70 is aligned with the exhaust outlet 212 of the liquid storage box 210, and such that the connection port 71 directly connects and communicates the exhaust outlet 212 of the liquid storage box 210 in a butt joint manner, and thus, the exhaust outlet 212 of the liquid storage box 210 and the exhaust tube 70 may also be communicated, and only the connection position needs to be sealed to prevent air leakage.

Based on any one of the above embodiments, the water dispenser liner 10 further includes a water outlet assembly 30, and the water outlet assembly 30 includes a water outlet pipe 31 and a water outlet valve 32; wherein the outlet pipe 31 is adapted to communicate the outlet 12 with the outlet end 50; the outlet valve 32 is mounted on the outlet pipe 31. Specifically, one end of the water outlet pipe 31 is connected with the water outlet 12 of the refrigeration liner, and the other end of the water outlet pipe 31 is connected with the water outlet end 50; the water outlet valve 32 is mounted on the water outlet pipe 31 and used for adjusting the on-off of the water flow from the water outlet pipe 31. The outlet valve 32 may be selected as a solenoid valve. The outlet valve 32 is normally closed, and the outlet valve 32 is switched to an open state only when the water dispenser is used to take water.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
