Abstract

The utility model provides a domestic water heater, comprising a tank body 5 and a heating pipe 3 which is positioned in the tank body 5. The utility model is characterized in that a circulating working medium inlet 2 is positioned on the upper part of the box body 5 and a circulating working medium outlet 10 is positioned on the lower part of the box body 5; the circulating working medium inlet 2 and the circulating working medium outlet 10 are communicated with the heating pipe 3; the upper part of the box body 5 is provided with a water inlet 1 and a water outlet 8, and is matched with a regulating valve 6. The utility model has the advantages that the water storage and the water adding are integrated; the structure is simple; the cost is low; the use is convenient.

Description

Pot-type boiler

The utility model belongs to heat-exchange apparatus, more properly says it is that a kind of what be mainly used in family is the water heater of thermal source with the warmer pipeline.

With warmer (comprising hot-water heating equipment and steam heating equipment) is the water heater of thermal source, mentioned for other people in known technology.For example,, the patent No. open January 25 nineteen ninety-five by Patent Office of the People's Republic of China is 94208307.5 " a kind of water heater ".This water heater comprises members such as casing, thermal-collecting tube, it is characterized in that thermal-collecting tube is arranged in the airtight casing, and the upper and lower port of thermal-collecting tube is opened respectively in the casing upper and lower part, also offers the import and the outlet of cycle fluid on the casing.In the use, cold water, is flowed out for utilization by lower port after heating up under the cycle fluid effect in casing through thermal-collecting tube.The weak point of this kind equipment is: in order to obtain the required suitable water temperature of water of taking a shower, thermal-collecting tube will adopt the comparatively coil arrangement of dense arrangement, thereby raw materials consumption is more; Simultaneously, this structure also is subjected to the restriction of water supply conditions, promptly when cutting off the water, can't use.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, reduces manufacturing cost, and uses convenient.

The utility model comprises casing and is arranged in the heating tube of casing, it is characterized in that: the cycle fluid outlet and the heating tube that are positioned at the cycle fluid import of casing top and are positioned at the casing below link; Water inlet and delivery port are being set on casing and are being equipped with control valve.

For the water temperature that keeps raising in the casing, at arranged outside one thermal insulation layer of casing.

The version of thermal insulation layer can be made multiple choices, for example loads the low material of the coefficient of heat conduction etc. in the interlayer.The preferred scheme of the utility model is: thermal insulation layer is a thermal insulation coatings layer.

For the ease of the adjustment of water temperature, the utility model is a water-supply-pipe in parallel between water inlet and water outlet, and on water-supply-pipe a control valve is installed.

Introduce an embodiment of the present utility model below in conjunction with Figure of description:

Figure of description 1 is a structural representation of the present utility model.

Among the figure, 1-water inlet, the import of 2-cycle fluid, 3-heating tube, 4-thermal insulation layer, 5-casing, 6-control valve, 7-spray head, 8-control valve, 9-delivery port, the outlet of 10-cycle fluid, 11-water-supply-pipe.

As shown in the figure, casing 5 is an obturator, and heating tube 3 is arranged in casing 5, adopts Zigzag type structure or coiled structure, to increase heat exchange area.The upper end of heating tube 3 is cycle fluid import 2, and the lower end of heating tube 3 is cycle fluid outlet 10, and heating tube 3 also inserts in the circulation waterway or vapour road of heating system.

The outer thermal insulation layers 4 for the thermal insulation coatings formation of casing 5 are provided with a water inlet 1 that can join with water supply pipe on the top of casing 5, the lower end of casing 5 is provided with a delivery port 9, and delivery port 9 can be installed spray head 7, can also adopt illustrated parallel-connection structure form.Entering the cycle fluid that cold water in the casing 5 stores and be heated by casing 5 in the pipe 3 through water inlet 1 heats.

The version that the utility model adopted makes the water that is ready for use in the casing 5 be heated the cycle fluid long-time heating of managing in 3, thereby the higher phenomenon of water temperature may appear when using, a water-supply-pipe 11 in parallel between water inlet 1 and delivery port 9 (control valve 6 outsides) for this reason, and a control valve 8 is installed, mixing of an amount of cold water controlled in cooperation by control valve 8 and control valve 6, makes water temperature reach satisfied effect.

In this embodiment, the pipeline of being drawn by delivery port 9 is provided with two outlets that have gate valve respectively, and an outlet has spray head 7, and another outlet is common outlet.

The utility model has the advantages that: the collection water storage is heated to be one, and simple in structure, cost is low, makes With convenient.
