Summary of the invention

[0003] The utility model aims to provide a technical solution for a multifunctional water purifier in view of the deficiencies in the prior art. The structure is compact and reasonable, the overall volume is small, and the structure is simple. The water purifier can realize the function of making hot water through the heating system, and can realize the functions of making ice and ice water at the same time through the refrigeration system, so that the same water purifier can realize multiple functions of making hot water, making ice, and making ice water at the same time, effectively saving space and cost, and increasing the functionality of the system, improving the user experience, and is also equipped with a brewing device, so that the water purifier also has a brewing function, and the brewing device is rotatably arranged on the housing of the water purifier. When it is necessary to make tea, the brewing device with the tea bag placed is rotated into place, so that the water outlet portion just corresponds to the brewing device. When brewing is not needed, the brewing device is completely turned out from the water outlet portion, which does not affect the acquisition of hot and cold water. The design is ingenious and reasonable, and the practicability is strong, which effectively increases the use function of the water purifier.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A multifunctional water purifier comprises a pure water tank and a water outlet, the water outlet is provided with a hot water outlet and a cold water outlet, and also comprises a water supply system, a heating system, a refrigeration system, a control unit and a brewing device. The water supply system is connected with the pure water tank, and the filtered water is provided to the pure water tank through the water supply system. The heating system is arranged between the pure water tank and the water outlet, and the water outputted from the pure water tank is heated and heated by the heating system, and then flows out from the hot water outlet; the refrigeration system comprises an integrated bracket, a water storage box, an evaporator and an ice tank, the water storage box is rotatably arranged in the receiving cavity of the integrated bracket, and the water storage box is connected with a driving motor. The water purifier is connected to the machine, and the driving motor provides a power source to drive the water storage box to rotate, so as to adjust the water storage box to rotate according to different states. The evaporator is arranged in the water storage box, the accommodating chamber is provided with a water inlet, the bottom of the accommodating chamber is provided with a water outlet and an ice outlet, the ice gallbladder is connected with the water outlet, the ice gallbladder is connected with the pure water tank through a water pump 1, the ice gallbladder is connected with the water inlet through a water pump 2, and the ice gallbladder is connected with the cold water outlet through a water pump 3; the water supply system, the heating system, and the refrigeration system are all connected with the control unit; the brewing device is arranged below the water outlet, and the brewing device is rotatably arranged on the casing of the water purifier.

[0006] Furthermore, the water supply system includes a raw water tank, a tap water inlet, a three-way solenoid valve, a self-priming pump and a composite filter element. A partition is arranged in the raw water tank, and the partition divides the raw water tank into a waste water chamber and a raw water chamber. The raw water chamber is connected to the first inlet of the three-way solenoid valve, the tap water inlet is connected to the second inlet of the three-way solenoid valve, the outlet of the three-way solenoid valve is connected to the self-priming pump, the self-priming pump is connected to the composite filter element, a raw water TD sensor is arranged on the pipeline between the self-priming pump and the composite filter element, and the water quality of the raw water is monitored in real time by the raw water TD sensor, the composite filter element is connected to the pure water tank, a pure water TDS sensor is arranged on the pipeline between the composite filter element and the pure water tank, and the water quality of the pure water after filtering by the composite filter element is monitored in real time by the pure water TDS sensor, the bottom of the composite filter element is connected to the waste water chamber through a pipeline, and a waste water ratio solenoid valve is arranged on the pipeline between the composite filter element and the waste water chamber.

[0007] The design is ingenious and reasonable. The partition plate divides the internal cavity of the raw water tank into a wastewater cavity and a raw water cavity to achieve functional differences. The raw water cavity is used to place raw water, and the wastewater cavity is used to collect concentrated wastewater in the composite filter element. A float liquid level switch is also set in the wastewater cavity. The float liquid level switch senses the water level in the wastewater cavity to prevent the wastewater in the wastewater cavity from overflowing into the raw water cavity, thereby avoiding the increase of raw water TDS during use, greatly protecting the service life of the composite filter element. The pure water filtered by the composite filter element enters the pure water tank for placement, and a high and low water level switch is also set in the pure water tank. When the high water level switch in the pure water tank has a signal, it means that the pure water in the pure water tank has reached a high level, and the control unit controls the self-priming pump to stop working.

[0008] The present application adopts a dual ingenious design of a raw water tank and a tap water inlet, which can realize two water supply methods. The first method is to supply water through the raw water tank, with the first inlet of the three-way solenoid valve opened and the second inlet closed (the AC channel is open and the BC channel is closed), so that the water in the raw water chamber flows to the self-priming pump through the three-way solenoid valve; the second method is to supply water through the tap water inlet, with the first inlet of the three-way solenoid valve closed and the second inlet opened (the AC channel is closed and the BC channel is open), and tap water flows in through the tap water inlet and flows to the self-priming pump through the three-way solenoid valve, so that when the water in the raw water chamber is not replenished in time, the raw water can continue to be provided directly through the tap water inlet.

[0009] The composite filter element contains polypropylene melt-blown cotton, front carbon, RO membrane and rear carbon to achieve multi-stage filtration, so that the filtered water quality is better and the drinking safety of drinking water is improved. Combining these filtering parts into a single composite filter element can save space for the whole machine and reduce costs. The concentrated wastewater in the composite filter element can be discharged into the wastewater chamber through a pipeline for recovery, and the discharge of concentrated wastewater can be controlled and adjusted by the wastewater ratio solenoid valve.

[0010] Furthermore, the heating system includes a water pump four and a heating body. The water pump four is connected between the heating body and the pure water tank, and the heating body is connected to the hot water outlet. When taking hot water, the water pump four pumps the pure water in the pure water tank into the heating body for heating, and the heated hot water flows out through the hot water outlet of the water outlet. When taking ice water, the water pump three pumps out the ice water in the ice tank and flows out from the cold water outlet of the water outlet. The water outlet is provided with a cold water inlet and a hot water inlet. There is an independent circulation channel between the cold water inlet and the cold water outlet, and there is another independent circulation channel between the hot water inlet and the hot water outlet. Two independent circulation channels are used to achieve separation between cold and hot water, effectively improving the experience.

[0011] Furthermore, the brewing device includes a cup holder, a brewing cup and a cup cover. The cup holder is rotatably hinged with the shell of the water purifier, and the brewing cup is matched and snapped onto the cup holder. A cup holder cover is arranged inside the cup holder, a buckle block is arranged on the inner side wall of the cup holder, and a buckle groove is arranged on the cup holder cover. The buckle groove corresponds to the buckle block one by one, and the buckle block is snapped into the corresponding buckle groove to realize the buckle installation between the cup holder cover and the cup holder. The brewing cup includes an outer shell layer and an inner liner layer, and a vacuum layer is formed between the outer shell layer and the inner liner layer. The cup cover is arranged on the top of the brewing cup, and a sealing ring is arranged at the connection between the cup cover and the brewing cup. The outer wall of the cup holder is also provided with positioning ribs and shaft holes. The positioning ribs can cooperate with the positioning grooves on the water purifier housing to achieve accurate positioning of the cup holder after it is rotated into place on the water purifier housing, ensuring that after the cup holder drives the brewing cup to rotate into place, the water inlet of the cup cover is exactly aligned with the hot water outlet on the water outlet. The shaft hole can cooperate with the pin to achieve the rotational installation of the cup holder at the water purifier housing, making it convenient to realize the rotation adjustment of the brewing device through the cup holder to meet different usage requirements. At the same time, a step groove is formed between the top of the inner liner layer and the outer shell layer, so that a coffee filter can be placed in the brewing cup. The head of the coffee filter is just limited and supported in the step groove, meeting the user's need to brew coffee, further increasing the use function of the brewing device, and making the user experience better.

[0012] The cup holder cover and the cup holder are assembled by buckling blocks and buckle grooves, which effectively ensures the overall firmness and reliability after assembly, ensures the cup holder's stable clamping support for the brewing cup, ensures structural stability, reasonable design, and convenient and simple installation and disassembly. The brewing cup adopts a double-layer structure of an outer shell layer and an inner liner layer, which can ensure the overall structural strength, and a vacuum layer is formed between the outer shell layer and the inner liner layer, so that the brewing cup has a better insulation effect, and can also play an anti-scalding function, improving the safety of use. The detachable design of the cup cover and the brewing cup can facilitate the placement of tea leaves, tea bags, coffee filters, etc. in the brewing cup, and is also convenient for cleaning the inside of the brewing cup. The design of the sealing ring can ensure the installation tightness and reliability between the cup cover and the brewing cup.

[0013] Furthermore, the cup cover is provided with a cup cover water inlet, and a sealing cover is provided at the cup cover water inlet. The sealing cover includes a sealing part and a counterweight part. The counterweight part is hinged to the cup cover through a connecting shaft 1, and the sealing part seals and blocks the cup cover water inlet. When water is poured into the brewing cup, the sealing part rotates downward under the pressure of water to open the cup cover water inlet. The structural design is ingenious and reasonable. The sealing cover is hingedly connected to the cup cover. In a natural state, the sealing cover seals and blocks the cup cover water inlet under its own gravity, which plays the role of dust shielding and steam overflow prevention. When water is poured into the brewing cup, after the water contacts the sealing cover, the sealing part will tilt downward under the action of water, exposing and opening the cup cover water inlet, so that water can smoothly enter the brewing cup from the cup cover water inlet. After the water filling is completed, the sealing cover will reset to block the cup cover water inlet.

[0014] Furthermore, a cup base is provided at the bottom of the brewing cup, a fixed bracket is provided inside the brewing cup, the fixed bracket is fixedly connected to the cup base, a silicone sleeve is provided between the fixed bracket and the brewing cup, a water outlet is provided on the fixed bracket, a tea filter is provided above the water outlet, the tea filter can filter and remove impurities from the tea water, and prevent the granular matter in the tea bag from flowing out of the water outlet, effectively improving the actual use experience, a sealing sleeve is provided on the outside of the water outlet, a limiting column is provided on the sealing sleeve, a limiting perforation is provided on the cup base, the top of the limiting column passes through the limiting perforation, and a limiting end is provided at the top of the limiting column, and the limiting end is limited on the cup base. The design of the cup base and the fixed bracket can enhance the structural strength of the brewing cup, and at the same time, it can facilitate the assembly between the brewing cup and the cup holder, and ensure the stability and reliability of the clamping between the brewing cup and the cup holder. The design of the silicone sleeve can improve the installation tightness and firmness between the fixed bracket and the brewing cup, and prevent the tea water from leaking out of the connection gap, so that the tea water can only flow out of the water outlet, and improve the use experience. The sealing sleeve can be made of silicone material, and the limiting columns and limiting perforations correspond one to one to achieve a snap-on installation between the sealing sleeve and the cup base. The limiting end head is then used to limit the limiting columns from detaching from the limiting perforations, effectively ensuring the connection stability and reliability between the sealing sleeve and the cup base.

[0015] Furthermore, a valve core assembly is arranged in the water outlet, and the valve core assembly includes a valve core body and a return compression spring. A silicone gasket is arranged on the upper part of the valve core body, and the silicone gasket is limited and blocked on the top surface of the water outlet. The lower part of the valve core body and the return compression spring are both located in the water outlet. The return compression spring is sleeved on the outer side of the valve core body. A limit protrusion is arranged at the bottom of the valve core body, and the return compression spring is limited between the limit protrusion and the top of the water outlet. A connecting rod is arranged below the valve core body, and the connecting rod includes an integrally formed handle portion and a sealing The sealing head and the handle part are rotatably arranged in the cup holder through the second connecting shaft, and a sealing surface is arranged on the sealing head, and a top convex point and a through hole are arranged in the center of the sealing head; the handle part is pressed downward, and the top convex point pushes the valve core body upward to open the water outlet, so that the water outlet is connected with the through hole, and the reset spring is compressed during the lifting and moving of the valve core body, and the sealing surface is attached to and squeezes the sealing sleeve; the handle part is loosened, and the valve core body is reset and moved downward under the rebound force of the reset spring, so that the opened water outlet is sealed and covered.

[0016] The structural design is compact and reasonable. When tea is not taken, the silicone gasket cooperates with the top of the valve core body to completely cover and seal the top surface of the water outlet, thereby ensuring the sealing effect and ensuring that tea will not flow out of the water outlet when tea is not taken, thereby improving the safety and reliability of use. The design of the limiting protrusion makes the reset compression spring always limited between the limiting protrusion and the top of the water outlet. When the connecting rod lifts the valve core body upward, the reset compression spring will be compressed, which is convenient for the subsequent downward movement and reset of the valve core body. One end of the handle is connected to the sealing head, and the other end of the handle extends to the outside of the cup holder, which is convenient for pressing the connecting rod. By pressing the extended end of the handle, the sealing head below the valve core body is tilted, and the top convex point lifts the valve core body upward to open the water outlet, so that tea can flow out of the water outlet, and then continue to flow downward along the through hole on the sealing head, and finally flows out from the outlet on the cup holder to achieve tea taking. The tea taking process is convenient and simple, and is convenient for actual operation. At the same time, in the process of the sealing head lifting the valve core body upward, the sealing surface on the sealing head will contact the sealing sleeve, compressing the sealing sleeve, so that the sealing sleeve and the sealing surface are tightly fitted, thereby effectively preventing tea from overflowing. When the connecting rod is released, the valve core body will reset under the rebound force of the reset compression spring to seal and block the water outlet, and the connecting rod will reset under the action of its own gravity and the auxiliary rebound action of the sealing sleeve.

[0017] Furthermore, a cam is connected to the other end of the water storage box, and micro switch 1 and micro switch 2 are arranged on the integrated bracket; when the driving motor drives the water storage box to rotate, when the cam touches micro switch 1, the water storage box rotates to a horizontal position; when the cam touches micro switch 2, the water storage box rotates to an inclined position. Through the design of micro switch 1 and micro switch 2 in conjunction with the cam, precise positioning of the water storage box during rotation can be achieved. When the cam hits micro switch 1, the water storage box rotates to a horizontal position in this state, and when the cam hits micro switch 2, the water storage box rotates to an inclined position in this state. The design is ingenious and reasonable, and the operation is more convenient.

[0018] Furthermore, the bottom surface of the accommodating cavity is an inclined surface, the water outlet is arranged at the low end of the bottom surface of the accommodating cavity, the ice outlet is arranged at the high end of the bottom surface of the accommodating cavity, an ice guide mesh plate and a water retaining rib are arranged in the accommodating cavity, the ice guide mesh plate is arranged obliquely in the accommodating cavity, the ice guide mesh plate includes a fixed end, a mesh plate body and a supporting end, the fixed end and the supporting end are respectively arranged at the two ends of the mesh plate body, a fixing hole is arranged on the fixed end, mesh holes are evenly arranged on the mesh plate body, a supporting slot is arranged on the supporting end, and the water retaining rib is vertically arranged between the ice outlet and the ice guide mesh plate. The fixed end, the mesh plate body and the supporting end are an integrated molding structure, which is convenient for actual processing and molding, and ensures the structural strength of the ice guide mesh plate itself, the fixing hole can facilitate the installation and fixation of the ice guide mesh plate in the accommodating cavity, and the supporting slot can facilitate the clamping and positioning of the ice guide mesh plate in the accommodating cavity, effectively ensuring the installation firmness and stability of the ice guide mesh plate in the accommodating cavity.

[0019] The structure is reasonably and cleverly arranged. The bottom surface of the accommodating cavity is designed to be an inclined surface, and the drain is also set at the low end of the bottom surface of the accommodating cavity, so that under the guidance of the inclined slope, water can quickly converge to the drain, and then enter the ice bladder below through the drain, and the water is discharged quickly without water accumulation. The ice guide mesh is designed to be inclined toward the ice outlet, which can guide the prepared ice cubes to slide along the ice guide mesh toward the ice outlet, so that the ice cubes can smoothly enter the ice box for storage, and the mesh holes on the ice guide mesh can separate water from ice cubes. Water falls directly into the bottom of the accommodating cavity below the ice guide mesh along the mesh holes, and finally flows out of the drain into the ice bladder below. The mesh holes can be round, long hole-shaped, etc. The water retaining rib can play a role in intercepting and blocking, effectively preventing water from flowing out of the ice outlet. The top surface height of the water retaining bar is not higher than the top low end height of the ice guide grid plate to avoid the water retaining bar hindering the sliding of ice cubes, making the sliding of ice cubes smoother, and leaving a certain distance between the water retaining bar and the ice guide grid plate to prevent water from flowing out from the top of the water retaining bar.

[0020] Furthermore, a temperature sensor and a float switch are provided in the ice liner. A polyurethane foam layer is provided on the inner wall of the ice liner. The polyurethane foam layer plays a role of heat preservation. The temperature sensor can be used to sense the temperature of the ice water placed in the ice liner, and the float switch is used to sense the water level in the ice liner.

[0021] The utility model has the following beneficial effects due to the adoption of the above technical solution:

The water purifier can realize the function of making hot water through the heating system, and can realize the functions of making ice and ice water at the same time through the refrigeration system, so that the same water purifier can realize multiple functions of making hot water, making ice and making ice water at the same time, effectively saving space and cost, increasing the functionality of the system, and improving the user experience. The utility model is also equipped with a brewing device, so that the water purifier also has a brewing function, and the brewing device is rotatably arranged on the casing of the water purifier. When it is necessary to make tea, the brewing device with the tea bag placed is rotated into place so that the water outlet portion just corresponds to the brewing device. When brewing is not needed, the brewing device is completely turned out from the water outlet portion, which does not affect the acquisition of hot and cold water. The design is ingenious and reasonable, and the practicability is strong. The use function of the water purifier is effectively increased. Moreover, the made ice is separated from the water to avoid water being poured on the ice to cause ice melting, so that the overall ice-making effect is better.

[0023] The evaporator of the utility model is a bullet-shaped evaporator. When making ice, the water pump 2 pumps the water in the ice liner from the water inlet on the integrated bracket into the water storage box, immersing the bullet head on the evaporator to a certain height. When the water in the water storage box overflows and enters the ice liner from the water outlet through the mesh on the ice guide mesh plate, the water pump 2 stops working and starts making ice. The temperature of the evaporator decreases, and the temperature of the water around the bullet head decreases and freezes. After a period of freezing, the driving motor drives the water storage box to rotate until the cam hits the micro switch 2. The water storage box is tilted and flipped to pour out the water inside. The water enters the ice tank from the drain port through the mesh holes on the ice guide mesh plate. The ice cubes are separated from the bullet head under the action of heat, slide onto the ice guide mesh plate, and then slide down from the ice outlet along the ice guide mesh plate. After a certain period of time after completing one ice making, the drive motor works to drive the water storage box to rotate to a horizontal state. When the cam hits the micro switch 1, the water storage box is reset, the water storage box rotates to a horizontal state, the drive motor stops, and when making ice again, the water pump 2 continues to work, and the above ice making steps are repeated.

[0024] When the utility model makes ice water, water pump 2 pumps the water in the ice liner from the water inlet on the integrated bracket into the water storage box, immerses the bullet head on the evaporator to a certain height, the water in the water storage box overflows, enters the ice liner from the water outlet through the mesh holes on the ice guide mesh plate, and circulates continuously, and at the same time the temperature of the evaporator is reduced, so that the water temperature around the bullet head is reduced, and the temperature on the evaporator is controlled by the control unit, so that the water is cooled without freezing at the same time, when the temperature sensor in the ice liner detects that the water temperature in the ice liner reaches about 5°C, water pump 2 stops working, and at the same time the driving motor works to drive the water storage box to rotate, until the cam abuts against the micro switch 2, the water storage box tilts and flips to pour out the water inside, and the water enters the ice liner from the water outlet through the mesh holes on the ice guide mesh plate, when the temperature sensor in the ice liner detects that the water temperature in the ice liner reaches about 10°C, the driving motor starts to drive the water storage box to rotate, so that the water storage box rotates to a horizontal state, and then the water pump 2 is started, and the above-mentioned ice water making process is circulated until the water temperature in the ice liner is cooled to about 5°C.

[0025] When brewing tea, the utility model opens the cup cover and puts tea leaves or tea bags into the brewing cup, then installs the cup cover on the brewing cup, and then rotates the cup holder, the cup holder drives the brewing cup to rotate in place, the hot water outlet on the water outlet just corresponds to the water inlet of the cup cover on the brewing device, and then injects hot water into the brewing cup through the hot water outlet. After brewing, press the handle to lift the valve core body upward, so that the water outlet is opened, and the tea flows from the brewing cup into the cup. The whole process of brewing and taking tea is convenient and simple. Moreover, the brewing device can also be used for brewing coffee, and it only needs to be used with a coffee filter, which increases the functionality of use, makes the user experience better, and meets the different needs of users. Moreover, the brewing cup and the cup holder are detachably installed, and the brewing cup can be taken out when it is not in use, and the cup holder can be used as the support and placement part when the cup takes water, shortening the water taking height of the cup, thereby effectively preventing water from splashing out, and the cup holder can also be used as the support and placement part of the ice box when taking ice.

The use function of the water purifier is effectively increased, and the ice and water after making are separated to avoid water pouring on the ice to cause ice melting, so that the overall ice making effect is better.

[0065] The evaporator 45 of the utility model is a bullet-shaped evaporator 45. When making ice, the water pump 52 pumps the water in the ice bladder 46 into the water storage box 44 from the water inlet 85 on the integrated bracket 43, and immerses the bullet head 65 on the evaporator 45 to a certain height. When the water in the water storage box 44 overflows and enters the ice bladder 46 from the water outlet 48 through the mesh 55 on the ice guide mesh plate 54, the water pump 52 stops working and starts making ice. The temperature of the evaporator 45 decreases, and the water temperature around the bullet head 65 decreases and freezes. After a period of freezing, the driving motor 50 drives the water storage box 44 to rotate until the cam 62 hits the micro switch 2 When the water in the water storage box 44 is turned over, the water enters the ice liner 46 from the water outlet 48 through the mesh 55 on the ice guide mesh plate 54. The ice cubes are separated from the bullet head 65 under the action of heat, slide onto the ice guide mesh plate 54, and then slide down from the ice outlet 49 along the ice guide mesh plate 54.
