Description

Technical Field

[0001] This utility model relates to the field of water dispensers, specifically a water dispenser with rapid heating capability. Background Technology

[0002] A water dispenser is a device that heats or cools bottled purified water for convenient drinking. Bottled water is placed on top of the machine and used in conjunction with bottled water dispensers. Water dispensers can be broadly categorized into three types: hot and warm, hot and cold, and hot, cold, warm, and cold. Hot and cold dispensers are further divided into semiconductor cooling water dispensers and compressor cooling water dispensers. Some also connect to a purified water source via pipeline and are used in conjunction with a water purifier. Pipeline water dispensers connect directly to the main water supply source using connectors, while others connect through a water purification system before reaching the main water supply source.

[0003] However, existing water dispensers have the following defects during operation: when cold water enters the water tank, the lack of preheating of the cold water using the temperature inside the water tank and the lack of a mechanism to slow down the flow of cold water cause the cold water to disturb the hot water layer, resulting in a rapid drop in the temperature of the hot water, which requires a long time to reheat. Utility Model Content

[0004] The present invention aims to provide a water dispenser with rapid heating, mainly to solve the technical problems of existing technology that lack the use of the internal temperature of the water tank to preheat cold water and lack a mechanism to slow down the flow rate of cold water. As a result, when cold water flows into the water tank, it disturbs the hot water layer, causing the hot water temperature to drop rapidly and requiring a long time to reheat.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A water dispenser with rapid heating capability includes a main body and a thermostat mounted on the door panel of the main body. A heating water tank is installed inside the main body. A purified water inlet solenoid valve is fixedly connected to the bottom side of the main body. The output end of the purified water inlet solenoid valve penetrates the inner wall of the main body. An anti-siphon check valve is fixedly connected to the output end of the purified water inlet solenoid valve. A multi-stage filter box is installed inside the main body. The output end of the anti-siphon check valve is fixedly connected to the top side of one side of the multi-stage filter box. The interior of the main body is close to the multi-stage filter box. A cold water solenoid valve is installed on the outside of the filter box, and a hot water solenoid valve is installed inside the water dispenser body near the cold water solenoid valve. The cold water solenoid valve and the hot water solenoid valve are connected to the multi-stage filter box through a three-way pipe. The output end of the hot water solenoid valve is fixedly connected to a tiered water inlet pipe. One end of the tiered water inlet pipe passes through the top of one side of the heating water tank and extends into the interior of the heating water tank. One end of the tiered water inlet pipe is fixedly connected to a cold water preheating U-shaped pipe. A heating mechanism is installed inside the heating water tank, and a temperature probe is embedded in the heating mechanism inside the heating water tank.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working Principle: Through the cooperation of thermostat, temperature probe and heating mechanism, the water temperature can be adjusted arbitrarily, the operation is simple, the water temperature of the heating tank is displayed in real time, and the laminar flow heating principle is adopted through the layered water inlet pipe, heating and boiling layer by layer, one layer boils and then heating another layer, moving the water in upwards layer by layer, each layer is intelligently heated once from low temperature to boiling, the water temperature fluctuates by no more than one degree above or below the set temperature. Under normal working conditions, the water flowing out each time is water at the set temperature. In this way, the water temperature can be flexibly selected from room temperature to boiling point to meet the needs of different scenarios, easily adapting to the low boiling point conditions in high-altitude areas. With the cold water preheating loop tube, the hot water in the heating tank can be used to preheat the cold water in the cold water preheating loop tube. At the same time, due to the function of the anti-siphon one-way valve, the water in the heating tank is guaranteed not to flow back.

[0009] 2. Beneficial effects:

[0010] (1) The water temperature can be adjusted arbitrarily by the thermostat, which is easy to operate and displays the water temperature of the heating tank in real time. The water temperature is heated layer by layer through the layered water inlet pipe using the principle of laminar flow heating. The water is heated to boiling layer by layer. Each layer is heated from low temperature to boiling once. The water temperature fluctuates by no more than one degree when heated to the set temperature. Under normal working conditions, the water flowing out each time is water at the set temperature. The water temperature can be flexibly selected from room temperature to boiling point to meet the needs of different scenarios and easily adapt to the low boiling point in high-altitude areas.

[0011] (2) The steam generated after the water boils or the water supply system fails through the release pipe. When combined with the cold water preheating loop pipe, the hot water inside the heating water tank can be used to preheat the cold water inside the cold water preheating loop pipe. At the same time, due to the function of the anti-siphon one-way valve, the water in the heating water tank will not flow back.

[0014] Preferably, the heating mechanism includes electric heating tubes, and several electric heating tubes are provided. The several electric heating tubes are all embedded in the bottom of one side of the heating water tank, and the several electric heating tubes are arranged in a linear array at equal intervals. Since the several electric heating tubes heat the water inside the heating water tank, all-round heating is formed to avoid heating blind spots.

[0015] Preferably, the heating water tank has a hot water outlet on one side and is connected to a hot water outlet pipe. The output end of the cold water solenoid valve is fixedly connected to a cold water outlet pipe. Both the hot water outlet pipe and the cold water outlet pipe extend through the top of the water dispenser body. An over-temperature protector is installed on the outer wall of the release pipe. Through the cooperation of the over-temperature protector and the liquid level sensor, a three-stage protection system is provided to prevent water shortage, overfilling, and dry burning, ensuring the safe operation of the equipment.

[0016] Preferably, a power switch is installed on the side of the water dispenser body near the thermostat, and a drain valve is fixedly connected to the bottom of the heating water tank, with the drain valve's output end penetrating the bottom rear side of the water dispenser body; the drain valve at the bottom of the heating water tank can completely drain the remaining water in the tank, effectively preventing secondary pollution of drinking water caused by long-term water accumulation.

[0017] Preferably, an electronic controller is installed inside the water dispenser body near the multi-stage filter box; the electronic controller is electrically connected to the cold water solenoid valve, hot water solenoid valve, purified water inlet solenoid valve, liquid level sensor, temperature sensor, electric heating element, over-temperature protector, and power switch; this facilitates comprehensive control of time, water level, and temperature by the electronic controller.

[0023] Please see Figs. 1-3 As shown, a water dispenser with rapid heating includes a water dispenser body 1, a thermostat 2 installed on the door panel of the water dispenser body 1, a heating water tank 5 inside the water dispenser body 1, a liquid level sensor 3 embedded inside the heating water tank 5, an insulation sleeve 6 on the outer wall of the heating water tank 5, and a release pipe 11 fixedly connected to the top of the heating water tank 5. The top of the release pipe 11 passes through the top of the water dispenser body 1. Since the thermostat 2 is located on the upper part of the door panel, the water temperature can be adjusted arbitrarily, the operation is simple, and the water temperature in the tank is displayed in real time. At the same time, the installation position is located in the dry part of the top of the door panel, and the low humidity environment can avoid the control system from malfunctioning. The release pipe 11 is used to release overflow water and steam. When the steam generated after the water boils or when the water supply system malfunctions, it is discharged through this pipe. When external purified water enters the heating water tank 5 from the purified water inlet solenoid valve 18;

[0024] The heating water tank 5 is equipped with a heating mechanism, which includes electric heating tubes 8. There are several electric heating tubes 8, which are embedded in the bottom of one side of the heating water tank 5. The electric heating tubes 8 are arranged in a linear array at equal intervals. A temperature probe 7 is embedded in the heating water tank 5 near the heating mechanism. The temperature probe 7 is located at the optimal position above the electric heating tubes 8, which can accurately control the water temperature.

[0025] A power switch 19 is installed on the side of the water dispenser body 1 near the thermostat 2. A drain valve is fixedly connected to the bottom of the heating water tank 5, and the output end of the drain valve passes through the bottom of the rear side of the water dispenser body 1. Through the drain valve at the bottom of the heating water tank 5, the remaining water in the tank can be completely drained, effectively avoiding secondary pollution of drinking water caused by long-term water accumulation.

[0026] A purified water inlet solenoid valve 18 is fixedly connected to the bottom side of one side of the water dispenser body 1. The output end of the purified water inlet solenoid valve 18 penetrates the inner wall of the water dispenser body 1. An anti-siphon check valve 9 is fixedly connected to the output end of the purified water inlet solenoid valve 18. A multi-stage filter box 4 is installed inside the water dispenser body 1. The output end of the anti-siphon check valve 9 is fixedly connected to the top side of one side of the multi-stage filter box 4. A cold water solenoid valve 15 is installed inside the water dispenser body 1 near the outside of the multi-stage filter box 4. A hot water solenoid valve 16 is installed on one side, and a hot water outlet is provided on one side of the heating water tank 5, which is connected to a hot water outlet pipe 10. The output end of the cold water solenoid valve 15 is fixedly connected to a cold water outlet pipe 20, and one end of both the hot water outlet pipe 10 and the cold water outlet pipe 20 passes through the top of the water dispenser body 1. An over-temperature protector 12 is installed on the outer wall of the release pipe 11. Through the cooperation of the over-temperature protector 12 and the liquid level sensor 3, a three-stage protection system can be established to prevent water shortage, prevent water overfill, and prevent dry burning, ensuring the safe operation of the equipment.

[0027] The cold water solenoid valve 15 and the hot water solenoid valve 16 are connected to the multi-stage filter box 4 via a three-way pipe. The output end of the hot water solenoid valve 16 is fixedly connected to a tiered inlet pipe 13. One end of the tiered inlet pipe 13 passes through the top of one side of the heating water tank 5 and extends into the interior of the heating water tank 5. The other end of the tiered inlet pipe 13 is fixedly connected to a cold water preheating loop pipe 14. The purified water is filtered again through the multi-stage filter box 4 and then introduced into the cold water solenoid valve 15 and the hot water solenoid valve 16 respectively through the three-way pipe. Cold water can be directly discharged through the cold water outlet pipe 20. One part is exported, and the other part is introduced into the cold water preheating loop tube 14 from the hot water solenoid valve 16. The hot water inside the heating water tank 5 is used to preheat the cold water inside the cold water preheating loop tube 14. The water outlet at the bottom of the cold water preheating loop tube 14 is set with a bevel, so the water is discharged evenly and slowly, effectively preventing the mixing of cold water and drinking water. The anti-siphon one-way valve 9 ensures that the water in the heating water tank 5 will not flow back. And because several electric heating tubes 8 heat the water inside the heating water tank 5, all-round heating is formed to avoid the occurrence of heating blind spots.

[0028] The layered water inlet pipe 13 adopts the principle of laminar flow heating, heating and boiling layer by layer. Each layer is heated before the next, moving upwards layer by layer. Each layer is intelligently heated from a low temperature to boiling point, ensuring the water temperature fluctuates by no more than one degree Celsius when heated to the set temperature. Under normal operating conditions, the water flowing out each time is at the set temperature, avoiding mixed hot and cold water or repeatedly boiled water. This allows for flexible selection of water temperature from room temperature to boiling point, meeting the needs of different scenarios and easily adapting to the low boiling point conditions in high-altitude areas.

[0029] An electronic controller 17 is installed inside the water dispenser body 1 on the side near the multi-stage filter box 4; the electronic controller 17 is electrically connected to the cold water solenoid valve 15, the hot water solenoid valve 16, the purified water inlet solenoid valve 18, the liquid level sensor 3, the temperature sensor 7, the electric heating element 8, the over-temperature protector 12 and the power switch 19.

[0030] As described above, the specific implementation of this utility model is as follows: Since the thermostat 2 is located on the upper part of the equipment door panel, the water temperature can be adjusted arbitrarily, making operation simple and displaying the water tank temperature in real time. Simultaneously, its installation position is located on the dry part of the top of the door panel, and the low humidity environment can prevent malfunctions in the control system. The release pipe 11 is used to release overflow water and steam. When steam generated after the water boils or when the water supply system malfunctions, it is discharged through this pipe. When external purified water enters the heating water tank 5 through the purified water inlet solenoid valve 18, it is filtered again through the multi-stage filter box 4 and then through the three-way valve. The pipes are respectively introduced into the cold water solenoid valve 15 and the hot water solenoid valve 16. Cold water can be directly discharged through the cold water outlet pipe 20, while the other part is introduced into the cold water preheating loop pipe 14 through the hot water solenoid valve 16. The hot water inside the heating water tank 5 preheats the cold water inside the cold water preheating loop pipe 14. The bottom outlet of the cold water preheating loop pipe 14 is designed with a bevel, so the water flow is uniform and slow, effectively preventing the mixing of cold water and drinking water. The anti-siphon check valve 9 ensures that the water in the heating water tank 5 will not flow back. And because several electric heating tubes 8 heat the water inside the heating water tank 5... Water is heated to achieve all-around heating and avoid heating blind spots. The temperature probe 7 is positioned optimally above several electric heating elements 8 to precisely control the water temperature. Combined with the layered water inlet pipe 13, it employs the principle of laminar flow heating, heating each layer to boiling. One layer boils before the next is heated, with water moving upwards layer by layer. Each layer is intelligently heated from a low temperature to boiling, ensuring the water temperature does not fluctuate by more than one degree Celsius when heated to the set temperature. Under normal operating conditions, the water flowing out each time is at the set temperature, preventing unevenly heated or repeatedly boiled water. This method heats the water from room temperature... The boiling point can be flexibly selected to meet the needs of different scenarios, easily adapting to the low boiling point conditions in high-altitude areas. The heated water can be discharged through the hot water outlet pipe 10, thus achieving real-time small-volume heating. When the set water temperature is reached, it automatically enters a constant temperature working state. The drain valve at the bottom of the heated water tank 5 can completely empty the water tank, effectively avoiding secondary pollution of drinking water caused by long-term water accumulation. With the cooperation of the over-temperature protector 12 and the liquid level sensor 3, a three-stage protection system can be established to prevent water shortage, water overfill, and dry burning, ensuring safe operation of the equipment.
