Description

Circulating hot water apparatus

The utility model relates to hot water facility, particularly a kind of circulating hot water apparatus.

Use coal stove to do the family of kitchen range in town and country, people are in order to obtain hot water in the daily life, and the kettle that at first will adorn cold water is placed on coal furnace mouth and heats, and could pour out from kettle for people after the water heating and utilize.This method with coal stove and heated kettle water, when maximum shortcoming was used heated kettle water exactly, coal stove can not be used for cooking or cooking, and coal stove has all slatterned at waste heat at ordinary times.Jia Re water on the other hand, when kettle was not placed on the coal stove, the hot water in the kettle can not be incubated, and these bring very big inconvenience all for people's life.

The purpose of this utility model do not influence when a kind of hot water will be provided exactly cook, cooking, the waste heat that can make full use of coal stove at ordinary times again comes hot water, and the circulating hot water apparatus that can be incubated for a long time of the water after the heating.

The utility model is that this is existing like this, and it mainly is made up of coal stove, large water tank, flash heat transfer device, water pipe, valve.It is an outstanding large water tank of adorning a band heat-insulation layer above the coal stove that has annular inner water tank, between coal stove and large water tank, connect upper and lower admittedly two water pipes, one of two water pipes is communicated with annular inner water tank in the coal stove, and its other end then is communicated with the formation water loop with metal box in the large water tank.A distributive pipe is respectively connected in the centre of upper and lower water pipe, and the other end of two distributive pipes is communicated with two flexible pipes, and the port of two flexible pipes all is communicated with a flash heat transfer device.Lower vertical at downcomer is communicated with a cold water inlet, adorn a cold water control valve in the centre of cold water inlet, the water outlet side of control valve is adorned a bending hot water outlet pipe on cold water inlet, and on pipe, adorn a hot water control valve, between the influent side of cold water control valve on the cold water inlet and bending hot water outlet pipe and connect a cold water pipe, and install a cold water control valve at the middle part of cold water pipe, and adorn a water level meter and an overflow pipe in the side of large water tank, install a safety valve at the top of large water tank.During use, at first open the cold water control valve of water inlet pipe, then under the pressure of running water self by cold water inlet water filling in the cavity of the annular inner water tank in large water tank and coal stove and flash heat transfer device respectively, after these containers are filled with water, then turn off cold water control valve.Fired coal combustion in coal stove is used as and is cooked, using when fire is normal to be used of cooking, annular inner water tank in the coal stove then absorbs the heat around the stove heart, water is heated up, at this moment water in the large water tank and the water in the coal stove inner water tank form certain temperature difference, because the water proportion difference of different temperatures, the water proportion that temperature is high is little, the low water of temperature is than great, so just make the annular inner water tank that temperature is high water by upper hose up flow to be suspended on it the higher authorities large water tank in, and the cold water of bottom just flows in the annular inner water tank of coal stove by downcomer in the large water tank, circulate and form, along with the heat of the coal stove stove heart is constantly absorbed by annular inner water tank, this circulation goes round and begins again and constantly carries out, and so just can realize that the water of whole large water tank constantly heats up, and utilizes the coal stove heart purpose of waste heat on every side thereby reach.When coal stove is not cooked, cooking is with when fire, can be placed on the flash heat transfer device on the coal furnace mouth, the water of flash heat transfer device inner chamber is because of absorbing the heat of fire door, thus make the water of its inside can realize with large water tank in the constantly circulation fast of water of water.When people open the valve of hot-water line, just can obtain required hot water at hot water effluent's mouth of pipe.Simultaneously, the water yield by regulating the hot and cold water valve is with regard to the controlled temperature that heats hot water in the water outlet pipe.

The utility model energy savings, simple in structure, cost is low, and is safe and reliable, convenient and practical, and the resident family and the restaurant that are specially adapted to the vast burning coal in town and country use, and its appearance provides a kind of desirable circulating hot water apparatus for people.
