Abstract

The utility model relates to a water boiler, which is composed of a cold water tank and a water boiling tank, an automatic water supply device of a float valve is arranged in the cold water tank; a water pipe and an air pipe are respectively connected the cold water tank and the upper and the lower ends of the water boiling tank; a water outlet for boiled water is arranged on the upper part of the water boiling tank; a heating pipe is upwards inserted into the water boiling tank from the bottom of the water boiling tank; an insulating layer is arranged outside of the water boiling tank. The water boiler has simple structure; after the cold water is conducted with the electricity for 1.5 minutes, the boiled water can be supplied. The boiled water can be always supplied without electricity cut; when the boiled water is not required, the electrical source can be cut off; the electricity can be saved. The utility model solves the problem of a common water boiler that the cold and the boiled water is easy to mix; the utility model is particularly suitable for the place that the boiled water is drunk by a plurality of people.

Description

The overflow-type rapid heating water boiler

The utility model belongs to field of electric heating, is specially adapted to boil water.

Prior art 92241436 provides a kind of full automatic watec-boiler, and its heating system places water storage tank, manufacturing cost height, not easy-maintaining; Adopt cold water pipe to export down at last, boiling water in heater, hot and cold water is mixed, drink influences healthy less than real boiling water.

The purpose of this utility model is to design a kind of boiler that boiling water is provided continuously simple in structure, quick.

The utility model is made up of cold water storage cistern and case to boil water, cold water storage cistern is equipped with the float-controlled valve automatic water supply device, be characterized in that water pipe connects the lower end of cold water storage cistern and case to boil water, tracheae connects the upper end of cold water storage cistern and case to boil water, the boiling water delivery port is on the top of case to boil water, heat-generating pipe upwards inserts case to boil water from the bottom of case to boil water, and case to boil water has heat-insulation layer for long tubular outside it.

The utility model is simple in structure, and cold water is switched on just the boiling water supply in about 1.5 minutes, as long as do not cut off the power supply the boiling water supply is not just arranged always; When not needing boiling water, cutting off the electricity supply gets final product, thereby also relatively power saving.

The utility model embodiment adopts body structure, and case 8 to boil water is long tubulars, and volume is less, and about 4 liters, to be convenient to unboiled water is boiled fast, its bottom opening inserts heat-generating pipe 10, with O-ring seal and bolted; Case 8 lower end side to boil water have a water inlet pipe 12 to communicate with cold water storage cistern 9, and there are two holes the upper end, and high slightly hole connects escape pipe 7, and its top with cold water storage cistern 9 is communicated, and steam can enter cold water storage cistern 9, and low slightly hole 6 connects boiling water delivery port 2; Boiling water delivery port 2 is shapes of similar goose egg, can reduce pressure by water storage, makes water yield evenly smooth; Case 8 external application asbestos to boil water or foam parcel are made heat-insulation layer 19;

Cold water storage cistern 9 is T molding box bodies wide at the top and narrow at the bottom, on enclosing cover 1 is arranged, when the running water pipe lack of water, can open enclosing cover 1, manually add water; Four limits, casing upper end have four holes, wherein two ball float gate valve 16, excessive low water level protection device 17 are installed respectively, and it is water limited pore 11 that the another one hole picks out 7, one holes of tracheae; Cold water storage cistern 9 lower ends are provided with sewage draining exit 18, and its lower end has a hole to tap into water pipe 12 in addition; The magnetite 14 of the bottom dress of cold water storage cistern 9; Cold water storage cistern 9 casings transition position wide at the top and narrow at the bottom is equipped with 120 purpose stainless steel filter clothes 15, can filter unboiled water; Water inlet pipe 12 adopts the ferromagnetism stainless steel tube, its outer coil 13 that is tied with;

Unboiled water enters the cold water storage cistern 9 from ball float gate valve 16, and when reaching certain water level, ball float gate valve 16 closes water automatically; Unboiled water filters through filter cloth 15, by magnetite 14 and coil 13 magnetization, enters case 8 to boil water through water inlet pipe 12 then again, and behind the water level balance of cold water storage cistern 9 and case to boil water 8, current promptly stop to flow.When the needs boiling water, press the button 5, indicator lamp 4 is bright, heat-generating pipe 10 is started working, and in less than 2 minutes time, the water in the case 8 to boil water will be boiled, according to the principle that cold water sinks, hot water rises, boiling water rises automatically, flows out through delivery port 2, and steam then flows to cold water storage cistern 9 from escape pipe 7; After boiling water flowed out some, the water level of case 8 to boil water will descend, the water meeting automatic stream case 8 to boil water of cold water storage cistern 9, and after the water level of cold water storage cistern 9 descended, ball float gate valve 16 can be opened, and replenished running water; If the lack of water situation occurs, the water level of cold water storage cistern 9 is lower than predetermined water level, and excessive low water level protection device 17 can be cut off the electricity supply, and heat-generating pipe 10 can not switched on, and prevents dry combustion method; Dipperstick 3 is the water levels that are used for representing cold water storage cistern 9.
