Description

Cold and hot boiling water machine water route control device

The utility model relates to a kind of device, particularly a kind of cold and hot boiling water machine water route control device.

When the boiling water in the existing cold and hot boiler becomes warm water, spend the long time, or increase the length of water pipe, the material that takes consuming time, efficient is not high enough.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of structure ingenious, and is energy-efficient, can guarantee the cold and hot boiling water machine water route control device of water hygiene.

The purpose of this utility model can reach by following measure: the utility model comprises cold water tank, warm water cylinder, thermal water storage tank, magnetic valve, unidirectional non-return valve, calorifier, water-level detecting element, water pipe, it is characterized in that: the warm water cylinder sleeve is placed on the cold water tank bottom, thermal water storage tank is positioned at warm water cylinder top, between link to each other by connecting water pipe, thermal water storage tank is led to by unboiled water outlet pipe, magnetic valve, unidirectional reverse valve, calorifier, hot water upper hose in the bottom of cold water tank.

Fig. 1 is a water route of the present utility model structural representation;

Fig. 2 is the heating principle schematic of calorifier.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of cold water tank 1, warm water cylinder 2, thermal water storage tank 3, magnetic valve 4, unidirectional non-return valve 5, calorifier 6, water-level detecting element 7, water pipe 8 etc.

Water in the cold water tank 1 is by magnetic valve 4 controls, and when water was made in the circuit indication, unboiled water entered calorifier 6 (see figure 2)s through magnetic valve 4, unidirectional non-return valve 5; After normal-temperature water entered calorifier 6, through heating wire 6-1 heating, temperature progressively raise, and moisture content changes and forms the steam high pressure, will seethe with excitement and the water of sterilization pushes in the thermal water storage tank 3 by hot water upper hose 8-3, thereby had guaranteed the health of drinking water.

Warm water cylinder 2 is mounted on cold water tank 1 bottom, when thermal water storage tank 3 water levels reach certain altitude, promptly by tube connector 8-1 hot boiling water is pressed in the warm water cylinder 2.The hot boiling water that is stored in this barrel can only enter into warm water cylinder 2 because of the reason of height of water level difference, and can not get back in the thermal water storage tank 3.When hot boiling water entered into the warm water cylinder, the unboiled water that promptly sees through normal temperature was taken heat energy out of, and is instant drinkable to warm boiling water.The thermal energy storage that normal-temperature water is taken out of is in cold water tank 1, and is to boil water immediately during because of this machine water, and heat energy circulates again and enters calorifier, with recuperation of heat, improved the efficient of thermal energy exchange.Hot water can flow out from hot water outlet pipe 8-4 in addition; Warm water can flow out from water outlet pipe 8-5.

Water-level detecting element 7 places cold water tank 1 below respectively, thermal water storage tank or warm water cylinder top.The hot water that enters in the thermal water storage tank 3 has reached vaporization high temperature, under suitably perfect heat-retaining condition, uses the low-power heater just can guarantee hot water in certain temperature, need not temperature controller control.

The utility model has following advantage compared to existing technology: simple and ingenious structure, improved Heat exchanger effectiveness, energy-saving effect is obvious, and can guarantee the health of drinking water.

Claims (1)
