Large-flow immediately-heating water-drinking machine

Abstract

The present invention provides a large-flow instant drinking machine. It includes the following several portions: drinking machine water inlet, drinking machine water outlet, pipeline and valve, flow-regulating device, pipeline electroheater and container electroheater. Said invention also provides the connection mode of all the above-mentioned portions and the working principle of said drinking machine.

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...

AI Technical Summary

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
