Description

Technical Field

[0001] The present invention relates to the technical field of water dispensers, and in particular to a water dispenser device. Background Art

[0002] A water dispenser is a common household appliance that is used to provide heated or cooled water for people's daily drinking.

[0003] For example:

[0004] A water dispenser with a heat preservation function, the publication number is: CN108420315A. By providing a cavity on the water dispenser body, a water bucket in the cavity, and a heat preservation tank in the cavity, the heated water in the water bucket can be well insulated, so that there is no need to heat and reheat the water in the water bucket, so that it is not easy to form "thousands of boiling water", and resources and power are saved at the same time. Heat preservation and heat insulation layers are fixedly provided on both sides of the inner wall of the cavity 2, which can better keep the water in the water bucket warm.

[0005] as well as:

[0006] A multifunctional energy-saving water dispenser, publication number: CN204708632U. After the user sets the required water temperature, water volume and repeated heating temperature and returns to the main interface of the touch-type liquid crystal display screen, the user can start the water dispenser through the "start\stop" button. When the water dispenser is started, the microprocessor will drive the solenoid valve to open, and at the same time, the flow detection module will start to detect the amount of water flowing into the heating inner tank. When the measured water volume is consistent with the water volume set by the user, the solenoid valve is closed, and the heater control switch is controlled to close to start heating the heater. After that, the microprocessor will collect the temperature signal output by the temperature sensor in real time, and display the temperature in real time in the display area of ​​the main interface. The heater state is displayed as "heating". At the same time, the detected temperature signal is compared with the temperature value set by the user. When the two are consistent, the microprocessor will control the heater control switch to disconnect to stop the heater from heating, and display the word "keep warm" in the display area of ​​the main interface. At the same time, the alarm module is driven to issue a voice prompt of "heating completed" to remind the user to take water in time. If the user takes away the heated water in time and the liquid level detection module does not detect the liquid level signal, the number of heating times N stored in the system will automatically return to zero and the controller will enter standby mode; otherwise, if the user does not take away the heated water in time, when the water temperature naturally drops to the repeated heating temperature, the heater will reheat the water and display the words "Nth heating" in the main interface display area.

[0007] However, in actual use, the sizes of the thermal insulation tank and the heating tank are fixed, so the maximum amount of water that can be stored is fixed. When the water dispenser is used by more people, the maximum amount of water stored in the thermal insulation tank and the heating tank may not be able to meet the use of multiple people at one time. Therefore, it is necessary to wait for the thermal insulation tank and the heating tank to refill water and then heat up, which takes time. When fewer people use it, the amount of water stored in the thermal insulation tank and the heating tank is greater than the needs of people. Therefore, the water dispenser needs to waste more unnecessary electricity to heat or insulate the water in the thermal insulation tank and the heating tank, which results in power waste.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-12 , the present invention provides a technical solution:

[0040] A water dispenser device comprises a water dispenser housing 1, wherein a filtering device 2 for connecting to an external tap water pipe (e.g., a filter element commonly used in water purifier products on the market) is installed in the upper space inside the water dispenser housing 1, an independent chamber 3 connected to the water outlet of the filtering device 2 is installed in the middle position, a heating chamber 4 connected to the water outlet of the independent chamber 3 and a heat preservation chamber 5 connected to the water outlet at the bottom of the heating chamber 4 are installed at the left and right sides of the lower part respectively, a water pump 6 is connected between the water outlet at the bottom of the heating chamber 4 and the water inlet at the top of the heat preservation chamber 5, and the water pump 6 is used to transport the heated drinking water in the heating chamber 4 to the heat preservation chamber 5 for storage, the water outlets at the bottom of the independent chamber 3 and the heat preservation chamber 5 both have a port connected to an external drain valve, and the tap water enters the independent chamber 3 in the water dispenser housing 1 after being filtered by the filtering device 2, and the independent chamber 3 has a port connected to an external faucet (e.g., Figure 2 As shown): When the heating chamber 4 is empty, the tap water in the independent chamber 3 flows into the heating chamber 4, and the interface is disconnected. The heating chamber 4 is heated to a certain temperature and then stops heating. The hot water is introduced into the heat preservation chamber 5, and the heat preservation chamber 5 is connected to the external tap for water discharge (as shown). Figure 1 and Figure 2 As shown), the internal pressure of the heat preservation chamber 5 is reduced to a certain value, and the water in the heating chamber 4 that has been heated to a certain temperature is diverted to the heat preservation chamber 5. The heating chamber 4 is slidably connected with a piston shell 8, and a switch valve 13 is provided on the piston shell 8 and the piston shell 8 is used to control the amount of heated water in the heating chamber 4. The filter device 2 and the independent chamber 3, the independent chamber 3 and the heating chamber 4, and the water outlet at the bottom of the heating chamber 4 are all connected with a conduction valve. The switch valve 13 in the piston shell 8 is opened to realize that the tap water flowing from the independent chamber 3 into the heating chamber 4 is gathered at the bottom of the heating chamber 4 and heated and heated at the bottom of the chamber, and the height of the piston shell 8 is adjusted. The size distribution of the upper and lower spaces of the heating chamber 4 can be achieved. When fewer people are using it, the position of the piston shell 8 is lowered, so that the amount of water heated at one time is reduced. The reduction in the amount of water can increase the heating speed and avoid wasting electricity by heating excess water. When more people are using it, the position of the piston shell 8 is raised, so that the amount of water heated at one time becomes larger, that is, the amount of water heated at one time is enough for multiple people to use at the same time, avoiding repeated boiling of water, causing people to wait, and affecting the guest experience. In addition, by bringing the piston shell 8 close to the water surface, the gap at the water surface can be reduced, that is, ensuring that the generated heat is concentrated in the water body at the bottom of the heating chamber 4, ensuring the maximum utilization of the heat.

[0041] Embodiment 1: The bottom of the heating chamber 4 is rotatably connected with a screw rod 9 that is threadedly connected to the piston shell 8 and a through column 10 that is set through the piston shell 8 and is sealed by a bearing. The screw rod 9 and the through column 10 are distributed in parallel and along the center line direction of the heating chamber 4. The set screw rod 9 and through column 10 can ensure that the piston shell 8 will not rotate in the heating chamber 4, but can only rise and fall with the rotation of the screw rod 9, thereby realizing the height adjustment of the piston shell 8. An edge sealing ring 11 is provided between the side of the inner wall of the piston shell 8 and the inner wall of the heating chamber 4, and a center sealing ring 12 is provided between the inner center and the surface of the screw rod 9. A heating assembly is provided at the bottom of the heating chamber 4, and two screw rods are fixedly connected to the outer bottom of the heating chamber 4, respectively, for driving the screw rods. 9 and the motor 7 that rotates through the column 10, and the edge sealing ring 11 and the center sealing ring 12 that are set can be pushed from the inside and squeezed from the outside after the height of the piston shell 8 is adjusted, so that the edge sealing ring 11 can be used to fit the inner wall of the heating chamber 4 and the center sealing ring 12 can be used to fit the thread on the surface of the screw rod 9, so as to achieve sealing between the piston shell 8 and the screw rod 9 and between the piston shell 8 and the inner wall of the heating chamber 4 to prevent water leakage. In addition, during the lifting and lowering process of the piston shell 8, no thrust and pressure are generated on the edge sealing ring 11 and the center sealing ring 12, so as to ensure that the piston shell 8 can be smoothly lifted and lowered in the heating chamber 4. In addition, the heating component in this scheme can be an electric heating wire or a heating magnesium rod.

[0042] Embodiment 2: A plurality of first contact strips 14 distributed in an annular array and used to contact the inner side of the edge sealing ring 11 are inserted into the inner side of the piston shell 8, and a second contact strip 18 inserted into the inner bottom surface of the piston shell 8 is arranged between two adjacent first contact strips 14. The plurality of first contact strips 14 and the second contact strips 18 are arranged around the inner side of the edge sealing ring 11 in a circle, and the first contact strips 14 and the second contact strips 18 both slide along the radial direction of the piston shell 8. In actual use, the plurality of first contact strips 14 are first driven to move and push the inner side of the edge sealing ring 11, and then the second contact strips 18 are driven to move and push other areas inside the edge sealing ring 11. The plurality of first contact strips 14 and the second contact strips 18 can be used to achieve all-round extrusion and pushing of the inner side of the edge sealing ring 11. When the piston shell 8 needs to be raised or lowered, it is only necessary to pull the first contact strip 14 first, and then pull the second contact strip 18. The first contact strips 14 and the second contact strips 18 are used to move toward the direction of the screw 9 to achieve that the edge sealing ring 11 does not contact the inner wall of the heating chamber 4.

[0043] In addition, a first spring rod 16 is connected between the inner side of the first and second contact strips 14, 18 and the inner bottom surface of the piston shell 8, and a second spring rod 17 is fixedly connected to the inner bottom surface of the piston shell 8 near each first contact strip 14. The first spring rod 16 can use a spring rod on the market whose elastic potential energy is greater than the elastic potential energy of the edge sealing ring 11, and the first contact strip 14 and the second contact strip 18 are squeezed to the inner side of the edge sealing ring 11 by the thrust of the first spring rod 16. The first contact strip 14 is fixedly connected to the side of the screw rod 9 with a spring rod 17 that moves in a zigzag route and passes through the inner bottom surface of the piston shell 8 and the corresponding spring rod 17. The first pull wire 24 adjacent to the telescopic end of the second spring rod 17, and the inner bottom surface of the piston shell 8 are also provided with a first total pull rope 19 connected to the ends of several first pull wires 24, and one side of the surface of the first total pull rope 19 is connected to a first connector 30 that penetrates the surface of the piston shell 8. By pulling the first connector 30, the first pull wire 24 is pulled to move under the traction of the first total pull rope 19, so that the first contact strip 14 connected to the first pull wire 24 overcomes the thrust of the first spring rod 16 connected to it and extends toward the direction of the screw 9, i.e., ensures that the edge sealing ring 11 of this part does not fit the inner wall of the heating chamber 4 under the action of elastic contraction.

[0044] In addition: the second contact strip 18 is fixedly connected to the side of the screw rod 9 with a second pull wire 23 which moves in a zigzag route and passes through the inner bottom surface of the piston shell 8; the inner bottom surface of the piston shell 8 is also provided with a second main pull rope 20 which is connected to the ends of several second pull wires 23 and is located above the first main pull rope 19; the second main pull rope 20 is provided with a second connecting head 31 which passes through the surface of the piston shell 8 near the first connecting head 30; similarly, by pulling the second connecting head 31, the movement of several second pull wires 23 is achieved under the traction action of the second main pull rope 20, and then the corresponding second contact strip 18 is pulled by the second pull wire 23 to overcome the thrust of the first spring rod 16 connected thereto and move toward the screw rod 9.

[0045] In addition, the inner bottom surface of the piston housing 8 is rotatably connected with a first wire reel 27 sleeved on the through column 10, and the side of the through column 10 extends outwardly in a strip-shaped arrangement plugged into the inner side surface of the first wire reel 27. A second wire reel 28 is arranged above the first wire reel 27, which is fitted with the surface clearance of the through column 10 and is rotatably mounted on the inner top surface of the piston housing 8 through a volute spring. The first wire reel 27 is connected to the end surface of the first connector 30, the second wire reel 28 is connected to the end of the second connector 31, and the side surfaces of the second wire reel 28 and the first wire reel 27 opposite to each other are provided with a convex block 29 for overlapping. Fig. 9As shown, the two protrusions 29 are symmetrically arranged about the center line of the first winding drum 27 in the initial state, and the second winding drum 28 is arranged so that it will not rotate when it is not subjected to external force by using the spiral spring on its surface. Because the first winding drum 27 is plugged into the strip-shaped protrusion on the surface of the penetrating column 10, when the penetrating column 10 rotates, it will rotate relative to the second winding drum 28 and drive the first winding drum 27 to rotate synchronously. When the first winding drum 27 rotates, it will wind up the first connecting head 30, that is, pull the first connecting head 30. By selecting the second winding drum 28 with an elastic potential energy greater than the first spring rod 16, the first winding drum 28 will rotate relative to the second winding drum 28 and drive the first winding drum 27 to rotate synchronously. The spring rod 17 makes it possible for the first winding drum 27 to drive the protrusion 29 on its surface to rotate less than 180 degrees (the protrusion 29 on the first winding drum 27 does not contact the protrusion 29 on the second winding drum 28). At this time, the first spring rod 16 on the first contact strip 14 is forced to contract, while the second spring rod 17 maintains an elastically stretched state. When the first winding drum 27 drives the protrusion 29 on its surface to rotate less than 180 degrees (the protrusion 29 on the first winding drum 27 contacts the protrusion 29 on the second winding drum 28), the first spring rod 16 on the first contact strip 14 is in a fully contracted state. The first cable drum 27 is in a retracted state, and the side edge of the first abutment strip 14 abuts against the cylinder surface of the second spring rod 17 that is fixedly connected. At this time, when the first cable drum 27 continues to rotate, when the two protrusions 29 overlap, the first cable drum 27 will push the second cable drum 28 to overcome the elastic force of the spiral spring and rotate, and the second cable drum 28 is rotated to wind the second connector 31 to pull the second connector 31, and the second spring rod 17 is used to make the first pull wire 24 under tension penetrate the telescopic end of the second spring rod 17 when the two protrusions 29 are in contact and the first cable drum 27 pushes the second cable drum 28 to rotate. The first part of the spring rod 17 will be deformed and push the second spring rod 17 to elastically contract. The second spring rod 17 contracts to ensure that when the second contact bar 18 is pulled toward the direction of the screw rod 9, the first pull wire 24 is released to a certain length due to the contraction of the second spring rod 17, ensuring that the first contact bar 14 does not move, so that the first contact bar 14 and the second contact bar 18 can be moved toward the direction of the screw rod 9 in succession. In actual use, the contact surface between the first contact bar 14 and the second contact bar 18 can be selected as an inclined surface to ensure that the first contact bar 14 will not interfere when it is pulled away from between the two adjacent second contact bars 18.

[0046] Embodiment 3: A plurality of abutment blocks 15 distributed in an annular array are inserted into the inner bottom surface of the piston housing 8 and along the outer side of the central sealing ring 12, such as Fig.11 and Fig.12As shown, the abutment block 15 is inserted into the inner bottom surface of the piston shell 8 and slides along the radial direction of the piston shell 8. The outer side of the abutment block 15 is fixedly connected with a connecting frame 26 which is inclined and distributed in the radial direction of the piston shell 8. The inner bottom surface of the piston shell 8 is also rotatably connected with two rotating rings 21 which are distributed in upper and lower positions and are arranged on the same center line as the screw rod 9. A plurality of abutment blocks 15 are divided into two groups according to the number. The two groups of abutment blocks 15 are cross-distributed and the connecting frames 26 on the sides of the two groups of abutment blocks 15 are respectively plugged into the surfaces of the two rotating rings 21. The connecting part between the rotating ring 21 and the connecting frame 26 is a columnar protrusion. The rotating ring 21 at the upper position rotates under the action of external force, and the connecting frame 26 connected to the columnar part of its surface is affected by the abutment block 15 and can only be moved along the active Because the piston shell 8 moves in the radial direction and the connecting frame 26 is tilted, the connecting frame 26 will drive the contact block 15 connected thereto to move away from the screw rod 9, that is, half of the contact blocks 15 do not generate pressure on the outside of the center sealing ring 12. Therefore, this part of the center sealing ring 12 will be away from the screw rod 9 under the elastic reset action. Similarly, the rotation of the rotating ring 21 below can achieve the movement of the other half of the contact blocks 15 away from the screw rod 9, that is, the other half of the contact blocks 15 do not generate pressure on the outside of the center sealing ring 12, and the inner side of the center sealing ring 12 does not contact the surface of the screw rod 9, ensuring that when the screw rod 9 rotates, it can smoothly drive the piston shell 8 to rise and fall.

[0047] In addition, the same side of the two rotating rings 21 extends outward and is fixedly installed with a connecting spring 22 between the inside of the piston shell 8, and a traction line 25 is connected between the rotating ring 21 at the lower position and the connecting spring 22 and the first total pull rope 19, and between the rotating ring 21 at the lower position and the connecting spring 22 and the second total pull rope 20. Figure 5 and Figure 6 The tension of the connecting spring 22 can be used to keep the rotating ring 21 connected thereto as shown in FIG. Fig.11 The state shown is that a plurality of resistance blocks 15 form a complete ring shape and generate pressure on the outer side of the center sealing ring 12, so that a part of the inner area of ​​the center sealing ring 12 is elastically deformed and tightly fits the surface of the screw rod 9 and the piston shell 8 to achieve sealing. However, when the first total pull rope 19 is subjected to the pulling force of the first connecting head 30, it will also pull the traction line 25 on the lower rotating ring 21, and then through the traction of the traction line 25 at this position, the lower position rotating ring 21 is achieved to overcome the pulling force of the connecting spring 22 connected to it and rotate, so that a part of the resistance blocks 15 do not squeeze the outer side of the center sealing ring 12. Similarly, when the second total pull rope 20 is subjected to the pulling force of the second connecting head 31, it will also drive the upper traction line 25 connected to it to move, and the upper traction line 25 will pull the upper position rotating ring 21 to overcome the pulling force of the connecting spring 22 connected to it and rotate, so that another part of the resistance blocks 15 do not squeeze the outer side of the center sealing ring 12.

[0048] The use method and working principle of the device: Under normal circumstances, when the piston shell 8 is located in the heating chamber 4, the thrust of the first spring rod 16 is used to realize that the first contact strip 14 or the second contact strip 18 connected thereto is in a complete ring shape, and a thrust is generated on the inner side of the edge sealing ring 11, so that the outer wall of the edge sealing ring 11 fills the gap between the piston shell 8 and the inner wall of the heating chamber 4, and the tension of the connecting spring 22 is used to realize that the rotating ring 21 connected thereto is fixed, that is, a plurality of contact blocks 15 form a complete ring shape, and pressure is generated on the outer side of the center sealing ring 12, so that the inner part of the center sealing ring 12 is elastically deformed and tightly fits the surface of the screw rod 9 and the piston shell 8 to achieve When the amount of water heated in the heating chamber 4 at one time needs to be adjusted, the through column 10 only needs to be driven to rotate by the motor 7 on the bottom side of the heating chamber 4. The rotation of the through column 10 first drives the first winding drum 27 to rotate half a circle. When the first winding drum 27 rotates, it reels and wraps the first connecting head 30. The first connecting head 30 pulls the first total pull rope 19, and the first total pull rope 19 pulls the first pull wire 24 and the traction wire 25 at the lower position, so that the first contact strip 14 overcomes the thrust of the first spring rod 16 connected to it and releases the thrust in the edge sealing ring 11, and the traction wire 25 at the lower side pulls the rotating ring 21 at the lower side to rotate, and the partial contact block 1 is realized under the plug-in action with the connecting frame 26. The pressure on the outer side of the center sealing ring 12 is released. After the first winding drum 27 rotates half a circle, the protrusion 29 on the surface of the first winding drum 27 overlaps with the protrusion 29 on the surface of the second winding drum 28 and pushes the second winding drum 28 to rotate, and then the second winding drum 28 rotates to wind up the second connecting head 31, and the second connecting head 31 pulls the second main pull rope 20, and the second main pull rope 20 pulls the second pull wire 23 and the upper position traction wire 25, so that the second resistance strip 18 overcomes the thrust of the first spring rod 16 connected thereto and releases the thrust in the edge sealing ring 11, and the upper traction wire 25 pulls the upper rotating ring 21 to rotate, and another part is realized under the plugging action with the connecting frame 26. The separate resistance block 15 releases the pressure on the outer side of the center sealing ring 12, so that the edge sealing ring 11 is not in contact with the inner wall of the heating chamber 4, that is, no friction is generated, and the center sealing ring 12 is not in contact with the surface of the screw rod 9. When the screw rod 9 rotates, it drives the piston shell 8 to rise and fall. After rising and falling to the corresponding position, the through column 10 is reversed to sequentially release the second connecting head 31 and the first connecting head 30, that is, under the pulling force of the first spring rod 16 and the connecting spring 22, the first resistance strip 14 and the second resistance strip 18 can push the edge sealing ring 11 to seal the edge of the piston shell 8 and the inner wall of the heating chamber 4, and the resistance block 15 can push the center sealing ring 12 to seal the screw rod 9 and the inner wall of the piston shell 8.
