Abstract

The utility model relates to a fast-cooling boiled water machine, which can generate cool boiled water quickly and provide hot boiled water simultaneously. A heating container which uses an electric heater to boil the water is connected with a counterflow heat exchanger of which the outer side is provided with a heat insulation layer. A water inlet of a cold water pipeline of the heat exchanger is connected with tap water, and a water outlet of the cold water pipeline of the heat exchanger is connected with an inlet of the heating container. An outlet of the heating container is connected with a water inlet of a boiled water pipeline of the heat exchanger. The tap water flows in the heating container to be boiled after the tap water is preheated by the heat exchanger, and the boiled water is cooled into the cool boiled water after the boiled water flows out of the heat exchanger. The hot boiled water can be supplied directly by the heating container.

Description

Quick cooling water boiler

The utility model relates to a kind of use electrical heating and heat transfer technology generates cold boiling water fast, also can supply the quick cooling water boiler of hot boiling water simultaneously." boiling water " as herein described refers to water is heated near the boiling point resulting water after high temperature sterilization reaches national hygiene standard for drinking water.

The technology that current current electrical heating boils water is to utilize electric heater under the control of temperature controller water to be heated until boiled.But just drinkable after boiling water must cool off, so drinking water is also inconvenient in public.On the market existing cold (temperature) hot boiling water machine be with water boiled after, adopt static heat exchange mode that water cooling is lowered the temperature, or further freeze with the principle of compression refrigeration.Such cooling scheme or heat exchange efficiency are not high, or the complex structure refrigeration slowly.Therefore can't provide a large amount of cold boiling water fast, and the two has much room for improvement all aspect energy saving.

The purpose of this utility model be to provide a kind of more energy-conservation, generate cold boiling water more apace, also can supply the quick cooling water boiler of hot boiling water simultaneously, to adapt to the needs of public place.

The purpose of this utility model is achieved in that shown in figure (1), adopt a heating container (1), a contraflow heat exchanger (2), a cold boiled water pail (3) (can omit), pipeline connects according to following mode: contraflow heat exchanger (2) has the water pipeline of two reverse flows, and one is the cold water pipeline, and one is the boiling water pipeline, the water inlet of cold water pipeline connects running water, and delivery port connects the import of heating container (1); The water inlet of boiling water pipeline connects the outlet of heating container (1), and as being provided with cold boiled water pail in the machine, then the delivery port of boiling water pipeline connects cold boiled water pail (3).Under the control of control device, constitute the quick cooling water boiler that an energy is boiled with running water and cool off.

Electric heater (H) is equipped with in the bottom of the heating container that the utility model adopted (1), water temperature probe (T) is equipped with on top.Control device uses current electric water boiler general purpose control technology, utilize the break-make of temperature controller according to the detected water temperature T control electric heater of water temperature probe (T) (H), boiled to guarantee with the water in the heating container (1), be about to water and be heated to the temperature that meets sanitary standard for drinking water.

The structure of the contraflow heat exchanger that the utility model adopted (2) is generally bushing type, as shown in Figure 2, form by two pipes, a pipe is enclosed within another root pipe outside, boiling water and cold water are respectively from the space of reverse flow between interior pipe and two tubes, form the water pipeline of two reverse flows, i.e. premium on currency pipeline and cold water pipeline.Also can adopt Contiuum type, as shown in Figure 3, two pipes become the disjunctor pipe in directly making one, and disjunctor pipe inside comprises two groups of tube chambers, supply boiling water and cold water respectively from the reverse flow heat exchange.Heat exchanger is made by the good material of heat conductivilitys such as copper, aluminium, adds thermal insulation layer, to reduce heat loss.Because pipe is longer, spirality can be coiled or helical is tubular, to cooperate installing space.

During work, running water is after the cold water pipe inflow heating container (1) of contraflow heat exchanger (2) is boiled, and the boiled water pipe through contraflow heat exchanger (2) flows out again.The running water that flows into heating container (1) is flowed out the boiling water preheating of heating container (1) in contraflow heat exchanger (2), the boiling water of outflow heating container (1) is flowed into thermal capacitance device (1) in contraflow heat exchanger (2) running water is cooled to cold boiling water.This process is carried out continuously, running water just is preheated continuously, boiled, be cooled into cold boiling water again.Heating container (1) also has direct depotition cock (4) so that hot boiling water to be provided.

Convenient for water, it is standby to store cold boiling water that a cold boiled water pail (3) can be set.For this reason, establish water-level probe (S2) and (S3) in the cold boiled water pail (3), establish dynamoelectric water valve (K) before the cold water pipe water inlet of contraflow heat exchanger (2).Control device is according to water-level probe (S2) and the water level situation that (S3) provided, utilize the control of dynamoelectric water valve (K) realization to current, drive valve when water level is lower than (S2), water level closes valve when reaching (S3), can not overflow from cold boiled water pail (3) to guarantee cold boiling water.

For the consideration of security, also can in heating container (1), set up pressure probe (P), water-level probe (S1), mechanical compression easing valve (6), with the respective conditions of monitoring heating container (1).

Because the utility model adopts contraflow heat exchanger to carry out continuous fluid interchange, the heat exchange efficiency height, the heat transfer rate is fast, can be quickly that water is boiled, and boiling water is cooled to cold boiling water immediately.Because most of heat energy of emitting in the time of utilizing the boiling water cooling, so energy-saving effect is remarkable.

Below in conjunction with accompanying drawing and example the utility model is described further.
