Abstract

The utility model introduces a domestic quick water heater, being composed of a bladder type heat supplying water tank, an outer housing of an interlayer sleeve cylinder containing water and a connection pipe. The continuously running tap water is preheated through the outer housing, and then enters the water tank to be heated again to quickly heat up and the hot water flows out continuously. The water heater can uses various household stove, such as the cola stove, the methane stove, the liquefied petroleum gas range, etc., as the thermal sources. The utility model has the advantages of simple structure and is easy to process in batches.

Description

Domestic high-speed water-heating unit

The utility model is a kind of with the normal domestic use thermal source water continuous flow heater of coal stove, biogas stove, liquefied petroleum gas stove heating for example, can be wash one's face and rinse one's mouth, cooking, especially shower provide hot water fast.

Existing domestic hot water's device has electric heating shower and coiled water heater, the former power consumption and dangerous, and latter's complex structure, air consumption is big, and gas pressure promptly can not use after reducing, and cost is higher.

It is a kind of simple in structure that the utility model provides, and is common to the general cooking stove of family, thereby and can contact in pairs and utilize the quick water continuous-flow heating of eyes liquefied petroleum gas stove that the water heater of shower water can be provided.

The utility model is finished as follows, promptly is inserted in the main part heat supply water tank (2) of a courage formula drum as the design in the cover tubular shell (1) that it is big or small with generally family cooking stove, especially liquefied petroleum gas stove are complementary as shown in Figure 1.Different with common water tank is, running water is not to be transfused in the bulk containers, but heats in the courage formula bucket wall interlayer of being made by metallic plate by the pipeline input.In order to make full use of flue gas, to increase heat exchange area, shell (1) is also made water containing interlayer sleeve, so as to allow the cold water of input at first inject to carry out in the shell chuck preheating flows into water tank (2) then thus accelerate the programming rate of water.With the bottom of water tank (2) up and down aspect make the male and fomale(M﹠F) of with ribbing (9,10) respectively, be that the position of flue gas effect is also made with ribbing male and fomale(M﹠F) respectively to improve the heat exchange effect with the wall of outer container top of the upper inside wall of shell (1) and water tank (2).Water tank (2) casing and shell (1) are fixed by connector (11) as shown in Figure 1 and are made the two concentric keep certain intervals as flue.Water inlet pipe (3) connects with shell (1) pipe, for fear of the short circuit of water journey, preferably water inlet pipe (3) is inserted in the courage wall of shell (1) from top to bottom, and its length is near the height of shell.Shell (1) is then connect by connecting leg (6) pipe with heat supply water tank (2).The annular upper base facial canal of connecting leg (6) one ends and shell (1) connects, and the other end inserts in the courage wall of water tank (2) deeply to strengthen the heat exchange effect.Then the upper, annular bottom surface pipe of outlet pipe (4) and water tank (2) is connect and promptly constituted the fast water heater that the utility model provides.During use this water heater is placed on the kitchen range, connect water tap by water inlet pipe (3) (is convenient to tear open as adopting snap joint to be connected herein, the dress better effects if, as two water heaters of connecting use on the eyes kitchen range simultaneously, its attachment also preferably adopts snap joint), open tap then, heat exchange effect because of outer casing inner wall in the process of just gushing on by the bottom behind the running water input shell (1) of continuous-flow obtains preheating very soon, flow into the heating of heat supply water tank bottom by connecting leg (5) again through the water of pre-heating temperature elevation, and in the process of gushing once again, become required hot water and flow out continuously through outlet pipe (4) because of flue gas heats up once again to the heating of water tank (2) gall bladder wall by the bottom.Its flow and water temperature can directly be controlled by tap.Because flow and water temperature are inversely proportional to, when being used for shower thereby requiring big flow, can take to increase thermal source, the way of expansion flow process.The water heater that provides as above-mentioned the utility model not only can the single use but also the use of can connecting in pairs.This is more convenient favourable to eyes gas-cooker user.In order more effectively to control the temperature of discharge or water, also can go up configuration one choke valve (5) at water inlet pipe (3).Experimental results show that the water firing rate ideal of this water heater, common liquefied petroleum gas stove can make temperature of cold water rises to 45 ℃ in last one minute more than, offer the user then continuously.And structure is very simple, is easy to processing, is fit to produce in enormous quantities.
