Description

Technical Field

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

[0002] Water dispensers are a common household appliance, widely used in homes, offices, and public places, providing drinking water. Traditional water dispensers typically consist of a water tank with an inlet pipe connected to the top. Filtered municipal tap water enters the tank and is heated by a heater inside the tank to meet people's drinking needs.

[0003] However, after the filtered cold water enters from the top of the water tank, it mixes with the already heated water in the tank, causing raw water (unheated cold water) to mix with cooked water (hot water that has been heated to a boil), resulting in the problem of "yin and yang water". At the same time, after the cold water enters, it mixes with the hot water, lowering 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 multiple times, forming "thousand-boil water". "Yin and yang water" and "thousand-boil water" affect the taste of the water and reduce the quality of the water. In addition, after the cold water enters, the heater needs to heat all the water, which increases the heating time and affects the user experience. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0036] The present application embodiment discloses a commercial water dispenser. Figure 1 and Figure 2As shown, the water dispenser includes a housing 1, within which is housed a filter element 17 and a water tank 2. The filter element 17 filters impurities and contaminants from municipal tap water, purifying it before it enters the water tank 2, thereby improving water safety. The filter element 17 communicates with the water tank 2 via an inlet pipe 3, allowing filtered water to enter the water tank 2 for heating. A water outlet 19 is also provided on the exterior of the housing 1. In this embodiment, three water outlets 19 are provided, two of which communicate with the heating tank for hot water; one of which communicates with the filter element 17 for direct drinking of cold water, satisfying the user's water needs.

[0037] like Figure 3 As shown, a connecting plate 203 is fixedly connected to the water tank 2. The connecting plate 203 divides the water tank 2 into a drive area 201 and a water storage area 202. The drive area 201 is located above the water storage area 202. A driver 4 is connected to the drive area 201. Preferably, the driver 4 is an electric push rod. The body of the driver 4 is fixedly connected to the inner wall of the water tank 2 and is electrically connected to a controller. The connecting plate 203 divides the water tank 2 into the drive area 201 and the water storage area 202, reducing the possibility that water stored in the water storage area will affect the normal operation of the driver 4. A vent 2031 is formed on the connecting plate 203. An exhaust seat 2032 is fixedly connected to the connecting plate 203 and located within the exhaust seat 2032. The exhaust seat 2032 is connected to the steam condenser 10. Steam within the water tank 2 can enter the steam condenser 10 through the vent 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.

[0038] In addition, if Figure 3 As shown, the outside of the water tank 2 is wrapped with an insulation 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 .

[0039] like Figure 3As shown, the output end of the driver 4 is fixedly connected to a hollow connecting seat 401, which is located within the driver area 201. A connecting rod 5 is fixedly connected to the side of the connecting seat 401 away from the driver 4. One end of the connecting rod 5 passes through the exhaust seat 2032 and extends into the water storage area 202 to be fixedly connected to the partition 6. Under the control of the driver 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 is formed on the partition 6 to cooperate with the slide rail 9. The cooperation between the slide rail 9 and the slide groove allows the partition 6 to be smoothly raised and lowered within the water tank 2 under the control of the driver 4, reducing the possibility of the partition 6 tilting or getting stuck when moving within the water tank 2.

[0040] like Figure 3 As shown, the mouth of the water inlet pipe 3 is located on the side of the partition 6 away from the driving member 4. The partition 6 is provided with a water hole 601, through which the water flowing out of the water inlet pipe 3 can flow. The mouth of the water inlet pipe 3 is located at the bottom of the water tank 2. Because the density of hot water is lower than that of cold water, the hot water is located above the cold water. In this embodiment, the cold water is room temperature water. After entering the water tank 2 from the bottom, the cold water is located below the hot water, reducing the possibility of the newly added cold water mixing with the hot water, thereby reducing the possibility of "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 "yin and yang water".

[0041] like Figure 3 As shown, a support base 11 is also fixedly connected to the partition 6, and a heater 7 and a temperature sensor 8 are fixedly connected to the support base 11. A wiring cavity 12 is formed inside the support base 11, the partition 6, and the connecting rod 5. The wiring cavity 12 is connected to the connecting base 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 base 401 and are electrically connected to the controller. By allowing the wires 18 of the temperature sensor 8 and the heater 7 to extend out of the water tank 2 through the wiring cavity 12, the reliability of the temperature sensor 8 and the heater 7 maintaining normal operation when the partition 6 moves is improved.

[0042] It should be noted that, in this embodiment, the temperature sensor 8 is set to detect the water temperature in the range of 40 degrees to 90 degrees. After the temperature sensor 8 detects the water temperature, it transmits it to the controller through an electrical signal.

[0043] 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.

[0044] 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.

[0045] In the water dispenser of this application, the controller controls the simultaneous flow of water through the water inlet pipe 3 when a user draws water, maintaining the water level in the water tank at a stable level. During the process, new cold water enters the water inlet pipe 3, lowering the temperature around the temperature sensor 8. When the temperature sensor 8 detects a water temperature below 40°C, the controller activates the driver 4, which drives the heater 7 upward, causing it to heat only warm water.

[0046] Through the cooperation of the driving member 4 and the temperature sensor 8, the heater 7 is placed in the 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.

[0047] At the same time, when 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.

[0048] like Figure 3 As shown, the water tank 2 is also equipped with a high water level detector 13 and a protective water level detector 14. In this embodiment, the high water level detector 13 is a liquid level sensor; the protective water level detector 14 is also a liquid level sensor. The high water level detector 13 monitors the maximum 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 detector 13, the controller controls the water dispenser to stop refilling, reducing the possibility of overflow from overfilling the water tank 2 and improving the safety and stability of the normal operation of the water dispenser. The protective water level detector 14 monitors the minimum water level in the water tank 2 in real time. When the water level falls below the set value, it promptly sends a signal to the controller to control the water dispenser to refill water, reducing the possibility of the heater 7 drying out due to water shortage and improving the safety and reliability of the water dispenser. The partition 6 has slots for the high water level detector 13 and the protective water level detector 14 to pass through, reducing the possibility of collision between the partition 6 and the high water level detector 13 and the protective water level detector 14, respectively, during movement.

[0049] like Figure 3 As shown, a sewage outlet 15 is also provided at the bottom of the water tank 2, and a valve is provided on the sewage outlet 15. The sewage 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.

[0050] The implementation principle of a commercial water dispenser in the embodiment of this application is as follows:

[0051] 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.

[0052] When the water dispenser of the present application first begins operation, there is no water in the water tank 2, and the partition 6 is in its initial position, which is the maximum downward movement position of the partition 6. At this time, the nozzle of the water inlet pipe 3 is located below the partition 6. During the initial operation, the controller controls the amount of water flowing into the water inlet pipe 3 so that the water level in the water tank 2 reaches the protective water level detection member 14. After the protective water level detection member 14 detects the water level, the controller controls the heater 7 to heat the water. When the temperature sensor 8 detects that the water temperature is above 90 degrees, the controller controls the water inlet pipe 3 to continue to flow water to the high water level detection member 13.

[0053] 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.

[0054] After a user draws 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 below 40 degrees Celsius, the heater 7 begins to heat up. When the water temperature reaches a warm level between 40 and 90 degrees Celsius, the heater 7 stops heating, allowing the heater 7 to heat the warm water in this area.

[0055] 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.

[0056] 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.

[0057] The heater 7 in the water dispenser of the present application can heat the water from top to bottom, layer by layer, after the user draws water, reducing the possibility of "thousand-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 time the user waits for water. Water can be added while drawing water, thereby shortening the time to replenish water, further reducing the time the user waits for water, which is beneficial to users' high-frequency water use and improves the continuity of the hot water supply of the water dispenser.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
