Description

Self heating bath

The utility model belongs to the health daily necessities, particularly a kind of self-heating bathtub.

At present, the equipment of selling on the domestic market of bathing mainly contains pottery, plastic bath tub, and the permanent plant that is that metallic enamel bathtub, these bathtubs have is arranged again in recent years, as pottery, enamel bathtub, is used for hotel, hostel more, utilizes boiler central heating water.And plastic bath tub is mainly used in family, utilizes other heating equipment heat supply water.Other shower equipment also has the water heater of various models, as Shen Leman, five rings water heater etc., is used for washing shower more.But price is more expensive, and general family is difficult to bear owing to income is low, therefore, uses also not general.Because the present family housing condition of China is poor, seldom is furnished with the toilet.Commercially available bathtub volume is bigger, and inconvenience is used.

In view of the deficiency that above-mentioned existing bathtub exists, it is little that the purpose of this utility model provides a kind of floor space, in light weight, removable, self-heating bathtub.

In order to achieve the above object, the utility model is realized by following scheme: it is by heater, bathtub, bathtub support, and heat-exchanger rig, smoke box, smoke exhaust fan are formed.Bathtub is located on the support and divides upper and lower two parts, and last bathtub bottom is provided with and makes bathtub be divided into two-part bathtub base up and down.Burner is located at the heat-exchanger rig bottom, and heat-exchanger rig is located at down bathtub central space place, and is connected and composed successively by water inlet pipe, circulating valve, ring pipe and disk-shaped tube, outlet pipe, and outlet pipe is connected with following bathtub middle part.It is affixed that the smoke box openend of being located at down the bathtub outside and play bathtub openend pass through flange, and smoke exhaust fan is located on the support and with smoke box and is communicated with, and smoke box is communicated with many smoke pipes in being located at down bathtub.

Embodiment is further described the utility model below in conjunction with accompanying drawing.

Fig. 1 is the A-A cutaway view of the self-heating bathtub that provides of the utility model along Fig. 2;

Fig. 2 is the vertical view of the self-heating bathtub that provides of the utility model;

Fig. 3 is the C-C cutaway view of the self-heating bathtub that provides of the utility model along Fig. 1;

Fig. 4 is the D-D cutaway view of the self-heating bathtub that provides of the utility model along Fig. 1.

With reference to shown in Figure 1, bathtub is by last bathtub (5), bathtub base (4), and bathtub (10) is formed down, and last bathtub is made with rigid plastics or metal material punching press, and whole bathtub is arranged on the bathtub support (1), connects by flange (3).Following bathtub (10) welds one with the openend of smoke box (9) by flange, and many smoke pipe (8) one ends are communicated with smoke box, and the other end is communicated with bathtub middle part heat transfer space down, and outlet valve (2) is located at down bathtub bottom water supply and sewage and uses.Smoke exhaust fan (11) is located on the support and is communicated with smoke box.Spilling water valve (6) is located on the bathtub upper portion side wall, when water surpasses this, can overflow by this hole.Have a plurality of circular holes from the bathtub base (4) of going up as can be seen shown in Figure 2, go up bathtub so that water is injected.From as can be seen shown in Figure 3, heat-exchanger rig is by water inlet pipe (14), circulating valve (13), ring pipe and disk-shaped tube (12), delivery port pipe (18) connect successively, outlet pipe is fixed in bathtub middle part down, can be with being threaded, last bathtub base is made of lacing wire (16) and cushion block (15) for strengthening rigidity.Upper and lower bathtub flange connections can seal with vulcan fibre sealing gasket (7).As can be seen from Figure 4, be fuel savings, improve the thermal efficiency, guarantee safety, the distribution scenario of many smoke pipes is set in following bathtub, can adopt the 10-18 root.Heater (17) is located at the heat-exchanger rig bottom, can adopt pulsed electron igniting gas burner or general gas burner, makes fuel with coal gas or liquefied gas.

During use, at first circulating valve cuts out, with flexible pipe with water inlet pipe be connected with running water pipe, the burner joint is connected with gas pipe, opens the valve of water inlet pipe then, water filling in bathtub, the ignition combustion device is opened the smoke exhaust fan smoke evacuation.Cold water by water inlet pipe through ring pipe, disk-shaped tube, be injected into down in the bathtub from outlet pipe, the high-temperature flue gas that burning generates passes annular, dish type water pipe and the water made with copper pipe to carry out entering smoke pipe after the sufficient heat exchange, carry out heat exchange once more with the water in the following bathtub, utilize the waste heat of flue gas that water is heated.Useless flue gas after sufficient heat exchange enters smoke box, discharges outdoor by smoke exhaust fan and pipeline.Water is heated to uniform temperature simultaneously in the process of injecting bathtub, after bathtub is filled with hot water, can bathe.Should close inlet valve before bathing, gas valve, smoke exhaust fan stop water filling, burning and smoke evacuation.If the person of bathing needs any water of heat, at this moment can open circulating valve, close valve on the water inlet pipe, because outlet pipe is than circulation pipe height, have certain pressure reduction, after water was heated in ring pipe, disk-shaped tube, proportion diminished, upwards flows, goes up the water in the bathtub, temperature is lower, than great, flow downward, enter annular and dish type water pipe through circulating valve, formation circulates.Higher waterborne the floating of temperature in the same bathtub at present; Lower the falling under water of temperature in the last bathtub also forms circulation, and water is further heated; After reaching certain temperature, can close coal gas, smoke exhaust fan, burn-out and smoke evacuation, at this moment just can take a shower by aforesaid operations.If need hair washing, flushing when taking a shower, can on outlet pipe, connect shower nozzle with flexible pipe, open smoke exhaust fan, the ignition combustion device is a hot water supply function, uses for hair washing, flushing.Carry out shower if desired, should at first close circulating valve, open water inlet pipe, water filling in the bathtub downwards, following bathtub is filled with after the water, and the ignition combustion device is opened the smoke exhaust fan smoke evacuation simultaneously then, and promptly hot water supply function carries out shower.The temperature of water can be regulated burning capacity and inflow and regulate by regulating gas valve and water intaking valve.After shower finishes, open draining valve, sewage is entered downcomer.Open water intaking valve then and wash, after rinsing well, can be put into certain position, the time spent takes out of again, also can fixedly be placed in the toilet.

The utlity model has following advantage:

2. a basin is multiplex, not only can bathe (being bath in a tub) but also can shower, is particularly suitable for the northern China wide geographic area.

3. thermal efficiency height, fuel saving, the thermal efficiency ratio water heater is high by 15～20%.

4. install and use more convenient, comfortable, health.

5. product can seriation, can be made into the product of different size.
