New pattern heat-free pot instant heating type drinking machine

Abstract

The invention provides a novel instant heating drinking water machine without heat tank, comprising drainage outlet of fountain in the drinking water machine and valve, throttle device and electrical heater on the pipe between drainage outlets. Said electrical heater is set vertically. The water inlet is set at the bottom and the water outlet is connected with the water outlet of drinking water machine. Compared with prior technology, the invention is provided with following merits that the flow temperature at the tap for hot water can achieve the setting temperature of user and the flow temperature can be adjusted by user in stepless. It is also provided with fresh water quality, less steam, little noise, energy saving, no temperature transferring, simple structure, low cost, high stability and good safety.

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to a novel heat-free instant water dispenser. Background technique [0002] At present, most of the water dispensers with heating function on the market have hot tanks. 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 heated repeatedly, and what users get is "thousand boiling water", and the water quality is not fresh; [0005] 3. Repeated heating will cause a large waste of electric energy; [0006] 4. The water dispenser is often energized and...

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 heated repeatedly, and what the user gets is "thousand boiling water", and the water quality is not fresh;

[0005] 3. Repeated heating will cause a large waste of electric energy;

[0006] 4. The water dispenser is often energized and heated when the user is not on site, and there are potential electrical safety hazards

[0015] 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 lower electric heater installed horizontally, it has been filled with normal temperature water before the power is turned on. After the electric heater is turned 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.

[0016] 2. High energy consumption, high water consumption, and temperature change

One is that more energy is consumed on the steam that generates bubbles, and the steam takes away energy and causes energy waste; the other is that the steam enters the water bucket of the water dispenser through the air return pipe, causing the temperature of the water 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 and increase the secondary pollution of the water dispenser. Electricity

[0017] 3. After setting the upper electric heater and the lower electric heater, only two levels of outlet water temperature can be provided, resulting in a significant increase in structural complexity, increased cost, and decreased reliability

[0018] 4. Heating is accompanied by the generation and collapse of a large number of bubbles, so the noise is louder

[0019] 5. Since the steam-water mixture comes out of the electric heater, a steam-water separator must be installed, and the product structure is complicated and the cost is high

[0020] 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
