Description

The energy-conservation boiling water equipment of heat energy circulation

The invention belongs to liquid heating, especially relate to a kind of energy-conservation boiling water equipment of heat energy circulation.

Present boiling type boiling water equipment, for example the patent No. is that (notification number is CN2089143U to ZL90222006.3, the day for announcing is on November 20th, 91) disclosed boiling type automatic electric water boiler, and the present inventor is at the boiling type boiler for domestic of the same applying date application of the present invention, its primary structure all is made up of cold water storage cistern, case to boil water (drum in the boiler is case to boil water), boiling water storage bin and boiling water tedge, after water in the case to boil water was heated to boiling, the bubble of boiling was pressed into boiling water in the boiling water storage bin via the boiling water tedge and stores.Though this boiling water equipment can provide boiling water continuously, but do not utilize the device of boiling water waste heat, so the energy consumption that boils water is bigger.

Task of the present invention provides a kind of energy-conservation boiling water equipment that can utilize the boiling water waste heat.

For solving above-mentioned task, the solution that the present invention adopts is: on the basis of common boiling type boiling water equipment, increase boiling water and cold water thermal energy converter, have metallic walls to be divided into boiling water passage and cold water channel in boiling water and the cold water thermal energy converter; Cold water inlet, cold water delivery port, boiling water water inlet and boiling water delivery port are arranged on boiling water and the cold water thermal energy converter, cold water inlet is communicated with the cold water storage cistern bottom, the cold water delivery port is communicated with case to boil water, the boiling water delivery port is communicated with the boiling water storage bin, and the boiling water that the delivery port of boiling water tedge flows out imports the boiling water water inlet of boiling water and cold water thermal energy converter.When boiling water, cold water enters case to boil water from the bottom of cold water chamber via the cold water channel boiling water and the cold water thermal energy converter, cold water is heated to boiling in case to boil water after, because the effect of boiling bubble, the boiling water passage of boiling water in boiling water tedge and boiling water and cold water thermal energy converter enters the boiling water storage bin and stores, like this, in boiling water and cold water thermal energy converter, there are boiling water and cold water to pass through simultaneously from separately passage, and carry out heat exchange, the thermal energy transfer that is boiling water reduces temperature for the cold water face, just enter case to boil water after cold water then is preheated, thereby realized purpose of the present invention.

The boiling water of this equipment and cold water thermal energy converter comprise outer metal tube and at least one interior metal tube, and outer metal tube is enclosed within outside the interior metal tube.

The boiling water of this equipment and cold water thermal energy converter are more than one or one.

In the cold water storage cistern of this equipment water-level control apparatus is arranged, water-level control apparatus or employing ball float water level controller, or adopt the electronics water level controller.

Owing to adopted boiling water and cold water thermal energy converter in the above-mentioned solution, boiling water and cold water have carried out heat exchange in boiling water and cold water thermal energy converter, make cold water before entering case to boil water, obtain preheating, promptly there is partial heat energy in the process of boiling water, to circulate, thereby saved the required energy that boils water, heat exchange in boiling water and the cold water thermal energy converter is carried out fully more, and is energy-conservation many more.Can regulate the boiling water temperature that enters the boiling water storage bin according to the degree of heat exchange simultaneously,, then supply 60～70 ℃ boiling water summer, not only make things convenient for people to drink but also can improve degree of power conservation as supplying 85～90 ℃ boiling water winter.

Below in conjunction with drawings and Examples the present invention is done further detail explanation.
