Problems solved by technology

[0003] 1. The outlet water temperature is low;
[0004] 2. The water in the hot tank is often repeatedly heated to a very high temperature, and what the user gets is "thousand boiling water", and the water quality is not fresh;
[0005] 3. Because the water is repeatedly heated to a very high temperature, the temperature difference between the high-temperature hot tank and the air outside the tank is very large, the heat dissipation is fast, and the electric energy is wasted.
[0014] 1. The initial outlet water temperature is low and contains residual water that may be contaminated by bacteria
In the part of the pipeline connected to the water outlet of the horizontally installed lower electric heater, it has been filled with normal temperature water before the power is turned on. After the lower electric heater is powered on, the water will not be heated, and the rising air bubbles will bring the water to the steam-water separation. In the device, this is one; the other is that after the hot water valve and the electric heater are suddenly closed, under the action of thermal inertia, a part of the hot water will flow to the steam-water separator, and this part of the water will be intercepted by the hot water valve. Then it is cooled to normal temperature water, and this part of water becomes leftover water, which is likely to be polluted by bacteria after a long time, and cannot be heated when the electric heater is turned on again
As a result, the initial water temperature of the hot water faucet of the water dispenser is only about 70°C, or even lower, and the water quality is not fresh.
[0015] 2. High energy consumption, high water consumption, and temperature change
First, more energy is consumed on the steam that generates bubbles, and the steam takes away energy and causes energy waste; second, the steam enters the water bucket of the water dispenser through the air return pipe, causing the water temperature in the water bucket to rise and cause the temperature of the water dispenser to change. After the water temperature rises (for example, 35°C to 37°C), bacteria are more likely to breed, which aggravates the secondary pollution of the water dispenser. Waste of electricity
[0016] 3. After setting the upper electric heater and the lower electric heater, only two levels of outlet water temperature can be provided, and the structural complexity is significantly increased, the cost is increased, and the reliability is decreased.
[0017] 4. Heating is accompanied by the generation and collapse of a large number of bubbles, and the noise is loud
[0018] 5. Since the steam-water mixture comes out of the electric heater, a steam-water separator needs to be installed, and the product structure is more complicated and the cost is higher
[0019] 6. There is no device to detect whether there is water in the electric heater, and it does not have the function of preventing dry heating, which poses a great safety hazard
[0020] 7. The hot water outlet temperature is unstable
[0021] In addition, since water dispensers are usually used in residential and office places, the load that electrical sockets can bear is limited. In order to ensure the safety of electrical products, the power of water dispensers should not be designed to be very large, usually not exceeding 2 kilowatts. Therefore, the patented technology drinking water The hot water flow rate of the machine is small, about 250 ml per minute, and it takes several minutes to receive a cup of hot water, which is inconvenient to use

Embodiment 1

[0046] Embodiment 1: As shown in FIG. 1, the large-flow instant water dispenser of the present invention includes a water dispenser bucket 9, and on the pipeline between the water outlet 12 of the water dispenser bucket 9 and the water outlet 4 of the water dispenser, connect There are valves 13, throttling devices, pipeline electric heaters 1 and container electric heaters 17. The pipeline electric heater 1 is installed vertically inside the water dispenser housing 2, the water outlet is on the top, and the water inlet is on the bottom. The drinking water is heated to the power above the set temperature (for example, 85°C); the inner diameter of the water pipe in the pipeline electric heater 1 is not less than 15 mm, and its water outlet is connected to the water outlet 4 of the water dispenser; the valve 13 can be It is manual or automatic. Considering the convenience of automatic control, a normally closed solenoid valve is preferred; the water level 11 in the water bucket ...

Embodiment 2

[0051] Embodiment 2: As shown in FIG. 1 and FIG. 2 , the throttling device in this embodiment is an adjustable throttle valve 21 that can adjust the flow rate, and other parts are the same as in Embodiment 1. The throttling valve 21 matches the power of the pipeline electric heater 1, and the outlet water temperature can reach above 95° C. at the minimum flow rate, and above 70° C. at the maximum flow rate. It is convenient for users to obtain hot water of different temperatures according to their needs.

Embodiment 3

[0052] Embodiment 3: As shown in FIG. 1 and FIG. 3, this embodiment is a simplified structure of the present invention. On the pipeline between the water outlet 12 of the bucket and the water outlet 4 of the water dispenser, no valve is provided, and the housing of the water dispenser There is no thermostat on the body. In this case, the water level 11 in the bucket should be slightly lower than the highest position of the outlet pipeline of the pipeline electric heater 1. When the pipeline electric heater 1 is not powered on, because the water level in the bucket is lower than the highest position of the outlet pipeline of the pipeline electric heater 1, no water will come out from the hot water outlet 4 of the water dispenser; after the pipeline electric heater 1 is powered on, the When the water is heated and expands, the water level will be higher than the water level in the water bucket of the water dispenser, and hot water will start to come out from the 4 hot water outl...

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to a large-flow instant hot water dispenser. Background technique [0002] At present, most of the water dispensers with heating function on the market are provided with a hot tank, which is used to heat and store hot water. This water dispenser generally uses a thermostat to control the temperature. When the water temperature reaches the set upper limit temperature, it stops heating, and when the water temperature drops to the set lower limit temperature, it is powered on again for heating. The actual temperature of the hot water used by users is generally between 85°C and 93°C. Its main problems are: [0003] 1. The outlet water temperature is low; [0004] 2. The water in the hot tank is often repeatedly heated to a very high temperature, and the user gets "thousand boiling water", and the water quality is not fresh; [0005] 3. Because the water is repeatedly heated...
