Description

Technical Field

[0001] The present application relates to the field of drinking equipment, and in particular to a commercial drinking fountain. Background Art

[0002] As a common household appliance, water dispensers are widely used in homes, offices and public places to provide people with drinking water. Traditional water dispensers usually include a water tank with a water inlet pipe connected to the top of the water tank. After municipal tap water is filtered and enters the water tank from the top, it is heated by a heater located inside the water tank to meet people's water needs.

[0003] However, after the filtered cold water enters from the top of the water tank, it mixes with the heated water in the water tank, causing raw water (unheated cold water) to mix with cooked water (hot water after heating and boiling), resulting in the problem of "yin and yang water". At the same time, after the cold water enters, it mixes with the hot water and lowers the overall temperature of the water in the water tank, and the heater needs to reheat the water. This repeated heating process causes the water to be boiled many times, forming "thousand-boiled water". "Yin and yang water" and "thousand-boiled water" affect the taste of water and reduce the quality of water use. In addition, after the cold water enters, the heater needs to heat all the water, which prolongs the heating time and affects the user experience. Summary of the invention

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0029] The present application embodiment discloses a commercial water dispenser. Figure 1 and Figure 2 As shown, the water dispenser includes a housing 1, in which a filter element 17 and a water tank 2 are arranged. The filter element 17 can filter impurities and pollutants contained in municipal tap water, purify the water before it enters the water tank 2, and improve the safety of water quality. The filter element 17 is connected to the water tank 2 through the water inlet pipe 3, so that the filtered water enters the water tank 2 for heating, and a water outlet 19 is also arranged outside the housing 1. In this embodiment, three water outlets 19 are provided, two of which are connected to the heating box for hot water; one water outlet 19 is connected to the filter element 17, and cold water can be directly drunk to meet the user's water demand.

[0030] like Figure 3As shown, a connecting plate 203 is fixedly connected in the water tank 2, and the connecting plate 203 divides the water tank 2 into a driving area 201 and a water storage area 202, and the driving area 201 is located on the upper side of the water storage area 202. A driving member 4 is connected in the driving area 201, and preferably, the driving member 4 is an electric push rod, and the body of the driving member 4 is fixedly connected to the inner wall of the water tank 2, and the driving member 4 is electrically connected to the controller. The water tank 2 is divided into the driving area 201 and the water storage area 202 by the connecting plate 203, which reduces the possibility that the water stored in the water storage area affects the normal operation of the driving member 4. An exhaust hole 2031 is opened on the connecting plate 203, and an exhaust seat 2032 is fixedly connected to the connecting plate 203, and the exhaust hole 2031 is located in the exhaust seat 2032. The exhaust seat 2032 is connected to the steam condenser 10, and the steam in the water tank 2 can enter the steam condenser 10 through the exhaust hole 2031 and be discharged, reducing the possibility of safety hazards caused by excessive pressure in the water tank 2. The steam condenser 10 is wound around the water inlet pipe 3, which can effectively utilize the steam heat in the water tank 2 to preheat the cold water in the water inlet pipe 3, reducing the temperature shock caused by the cold water mixing with hot water after entering the water tank 2, thereby improving the heating efficiency of the heater 7 and further shortening the heating time.

[0031] In addition, if Figure 3 As shown, the outer side of the water tank 2 is wrapped with a heat-insulating layer 16 , which can reduce the heat exchange between the inside and outside of the water tank 2 and improve the stability of the water temperature in the water tank 2 .

[0032] like Figure 3 As shown, the output end of the driving member 4 is fixedly connected with a hollow connection seat 401, and the connection seat 401 is located in the driving area 201. A connecting rod 5 is fixedly connected to the side of the connection seat 401 away from the driving member 4. After one end of the connecting rod 5 passes through the exhaust seat 2032, it extends into the water storage area 202 and is fixedly connected to the partition 6. Under the control of the driving member 4, the connecting rod 5 can slide on the exhaust seat 2032. A slide rail 9 is fixedly connected to the inner wall of the water tank 2, and a slide groove that cooperates with the slide rail 9 is provided on the partition 6. Through the cooperation of the slide rail 9 and the slide groove, the partition 6 can be smoothly raised and lowered in the water tank 2 under the control of the driving member 4, reducing the possibility of the partition 6 tilting or getting stuck when moving in the water tank 2.

[0033] like Figure 3As shown, the mouth of the water inlet pipe 3 is located on the side of the partition 6 away from the driving member 4, and a water hole 601 is provided on the partition 6, and the water flowing out of the water inlet pipe 3 can pass through the water hole 601. The mouth of the water inlet pipe 3 is located at the bottom of the water tank 2. Since the density of hot water is less than that of cold water, the hot water is located on the upper side of the cold water. In this embodiment, the cold water is room temperature water. After entering from the bottom of the water tank 2, the cold water is located on the lower side of the hot water, which reduces the possibility of the newly added cold water mixing with the hot water, thereby reducing the possibility of producing "yin and yang water". At the same time, the partition 6 can separate the cold water and the hot water, further reducing the possibility of producing "yin and yang water".

[0034] like Figure 3 As shown, a support seat 11 is also fixedly connected to the partition 6, and a heater 7 and a temperature sensor 8 are fixedly connected to the support seat 11. A wiring cavity 12 is provided inside the support seat 11, the partition 6 and the connecting rod 5, and the wiring cavity 12 is connected to the connecting seat 401, so that the wires 18 of the heater 7 and the temperature sensor 8 extend out of the water tank 2 through the wiring cavity 12 and the connecting seat 401, and are electrically connected to the controller. The wires 18 of the temperature sensor 8 and the heater 7 extend out of the water tank 2 through the wiring cavity 12, which improves the reliability of the temperature sensor 8 and the heater 7 to maintain normal operation when moving with the partition 6.

[0035] It should be noted that, in the present embodiment, the water temperature detection range set by the temperature sensor 8 is 40 degrees to 90 degrees. After the temperature sensor 8 detects the water temperature, it transmits it to the controller via an electrical signal.

[0036] When the temperature sensor 8 detects that the water temperature is between 40 degrees and 90 degrees, the controller controls the driving member 4 to keep the heater 7 stationary, so that the heater 7 heats the warm water between 40 degrees and 90 degrees.

[0037] After the heater 7 heats the warm water to 90 degrees, the controller controls the driving member 4 to work, and the driving member 4 drives the heater 7 to move downward, and stops descending when it descends to the warm water area between 40 degrees and 90 degrees, so that the heater 7 only heats the warm water.

[0038] When the user takes water from the water dispenser of the present application, the controller can control the water inlet pipe 3 to simultaneously take in water, so that the water level in the water tank is maintained at a stable water level. During the user's water taking process, new cold water enters the water inlet pipe 3, and the cold water lowers the temperature around the temperature sensor 8. When the temperature sensor 8 detects that the water temperature is less than 40 degrees, the controller controls the driving member 4 to work, and the driving member 4 drives the heater 7 to move upward, so that the heater 7 only heats warm water.

[0039] Through the cooperation of the driving member 4 and the temperature sensor 8, the heater 7 is placed in a warm water area of ​​40 to 90 degrees. Compared with the heater 7 heating cold water into hot water above 90 degrees, heating water with a certain water temperature can heat the water faster, shorten the heating time, and reduce the waiting time for users to use water.

[0040] At the same time, while the user is taking water, there is still a certain amount of hot water in the water tank. After the heating pipe moves to the hot water area, it is heated layer by layer from top to bottom, which can produce hot water faster, which is conducive to the user's high-frequency use of hot water and improves the continuity of hot water supply.

[0041] like Figure 3 As shown, a high water level detection member 13 and a protective water level detection member 14 are also provided in the water tank 2. In this embodiment, the high water level detection member 13 is a liquid level sensor; the protective water level detection member 14 is also a liquid level sensor. The high water level detection member 13 can monitor the highest water level in the water tank 2 in real time. When the water level in the water tank 2 reaches the position of the high water level detection member 13, the controller controls the water dispenser to stop replenishing water, thereby reducing the possibility of overflow of the water tank 2 due to excessive water filling, and improving the safety and stability of the normal operation of the water dispenser. The protective water level detection member 14 can monitor the lowest water level in the water tank 2 in real time. When the water level is lower than the set value, a signal can be sent to the controller in time, and the water dispenser can be controlled to replenish water, thereby reducing the possibility of dry burning of the heater 7 due to lack of water, and improving the safety and reliability of the water dispenser. A notch is provided on the partition 6 for the high water level detection member 13 and the protective water level detection member 14 to pass through, thereby reducing the possibility of collision between the partition 6 and the high water level detection member 13 and the protective water level detection member 14 when the partition 6 moves.

[0042] like Figure 3 As shown, a drain outlet 15 is also provided at the bottom of the water tank 2, and a valve is provided on the drain outlet 15. The drain outlet 15 can discharge the sediment and dirt in the water tank 2, reducing the possibility of long-term accumulation of sediment and dirt leading to water quality deterioration or equipment damage, thereby improving the hygiene performance and service life of the water dispenser.

[0043] The implementation principle of a commercial water dispenser in the embodiment of the present application is: Cold water enters the bottom of the water tank 2 through the water inlet pipe 3, and the newly added cold water passes through the water hole 601 on the partition 6 and is heated by the heater 7.

[0044] When the water dispenser of the present application starts working for the first time, there is no water in the water tank 2, and the partition 6 is located at the initial position, which is the limit position of the partition 6 moving downward. At this time, the pipe mouth of the water inlet pipe 3 is located below the partition 6. When the water dispenser of the present application starts working for the first time, the controller controls the water inflow of the water inlet pipe 3 so that the water level in the water tank 2 is at the protective water level detection part 14. After the protective water level detection part 14 detects the water level, the controller controls the heater 7 to heat up. When the temperature sensor 8 detects that the water temperature is higher than 90 degrees, the controller controls the water inlet pipe 3 to continue to inflow water to the high water level detection part 13.

[0045] After the water in the water tank 2 reaches the high water level detection member 13, there is a certain amount of hot water in the water tank 2, which can meet the needs of the user. In this embodiment, when the user takes water, the controller controls the water inlet pipe 3 to replenish water at the same time, so that the water level in the water tank 2 is maintained at the high water level detection member 13.

[0046] After the user takes water, the hot water decreases, and the controller controls the water inlet pipe 3 to replenish water. As new cold water is added, the cold water lowers the water temperature around the temperature sensor 8. When the temperature sensor 8 detects that the water temperature is less than 40 degrees, the heater 7 starts to rise, and when it rises to warm water with a temperature of 40 to 90 degrees, the heater 7 stops rising, so that the heater 7 heats the warm water in this area.

[0047] When the heater 7 heats the water temperature to 90 degrees, the controller controls the driving member 4 to work, so that the heater 7 moves downward. When the temperature sensor 8 detects that the water temperature is 40 to 90 degrees, the heater 7 stops descending, so that the heater 7 heats the warm water in this area.

[0048] When the heater 7 is gradually heated and descends to the initial position, the area above the partition 6 is filled with hot water. At this time, the controller controls the driving member 4 to stop the heater 7 from moving and heating.

[0049] The heater 7 in the water dispenser of the present application can heat the water from top to bottom and layer by layer after the user takes water, reducing the possibility of "thousands of boiling water". Cold water enters from the bottom of the water tank 2, and cooperates with the function of the partition 6 to reduce the possibility of "yin and yang water". At the same time, the heater 7 heats water with a water temperature of 40 to 90 degrees, shortening the heating time, thereby reducing the user's waiting time for water. And water can be added while taking water, thereby shortening the water replenishment time, further reducing the user's waiting time for water, which is conducive to users' high-frequency water use and improves the continuity of the hot water supply of the water dispenser.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
