Description

Gas heated fast shower

The utility model is about rapid hot water (shower) device with the fuel combustion heating.

At present, the various domestic electric heating shower power consumption of selling on the market are very big, as the shower water yield be 90 liters/time, if water temperature is raised to 40 ℃ from 15 ℃, about 3000 watts power just can meet the demands.General civilian ammeter rated current is 2～3 amperes, and can the ammeter capacity hold to can stand and be worthy of consideration.Under the serious situation in short supply of the present supply of electric power of China, electric heating shower still should not generally be promoted the use of.Some local government and electric industry department have stipulated that the user uses the nonproductive electric heater more than 500 watts etc., issue extraordinary electrical equipment occupancy permit Fang Zhun and use.

The gas heater that a kind of approved product is arranged abroad generally uses, and domestic also have a manufacturer production.The heat exchanger of this water heater partly is that coiled pipe has tens square fins.The valve of water inlet and air inlet is the linkage that is mutually related.Automatically igniting.This water heater complex structure, price is more expensive, and non-general producer can make, and is subjected to the restriction of fuel type, installs and uses the strict demand that must meet product description, otherwise can't use.Minority unit and family have used this water heater.But,, still have any problem at present because this water heater is generally used in the restriction of many factors such as China majority living conditions.

The tube that burns gas in addition on the market is water heater easily, exists many shortcomings or deficiency, in use promptly, the dew that condenses on the heat-transfer area increases gradually, is dropped on the flame, makes rubescent, the incomplete combustion of flame, send sound, produce difficult unpleasant peculiar smell, the people is poisoned.The water of these dewfall that even more serious is can put out the flame on the cooking stove, causes security incident.

The purpose of this utility model provides a kind of fuel type that is not subjected to and limits, and is simple in structure, and handling ease is easy to use, safe and reliable, and low price can reach rapidly for the purpose with hot water.Be fit to current majority's living standard and living conditions, combustion gas rapid hot water (shower) device of very easily in urban and rural residents, promoting the use of.

Of the present utility model being constructed as follows:

Accompanying drawing is structure of the present utility model and schematic flow sheet.

The utility model has a circular jacket outside cylinder (2), and cold water enters (2) from taking over (1), and flows in the helical duct of (2) and in the helical duct in (3), (4), (5), (6) all kinds heat exchanger plates, goes out hot water by adapter 7. Each heat exchanger plates is made of clamping plate, (3) be conical with (5), diameter at the bottom of the vertebra is less than the inner diameter of urceolus, (4) be cone platform shape with (6), the circular hole that differs in size is opened respectively on the frustum top, (4) diameter at the bottom of the vertebra equates with the inner diameter of urceolus, and the diameter at (5) cone end is less than the inner diameter of urceolus. Linked by tubule (a) between urceolus and each heat exchanger plates. The heat exchanger bottom directly contacts with cooking stove (9). Cold water after take over (1) and be full of water heater, is lighted the coal gas of (9). Baffling upwards flows in the circular hole of high-temperature fuel gas crack and heat exchanger plates between urceolus (2) and heat exchanger plates (6), (5), (4), (3), carry out heat exchange at heat-transfer area, low temperature waste gas is discharged from the upper end end socket (8) of water heater, the coolant-temperature gage of continuous-flow progressively raises, and reaches rapidly the purpose of using hot water or shower.

Combustion gas contains many gases that can generate water, thereby contains the water of a certain amount of steam condition in combustion products, and these water vapours are below dew-point temperature, inevitable dewfall Cheng Shui, these water go out outside the device along the swash plate surface current, can not be dropped on the flame, can not put out the flame on the cooking stove.

Experimental result is lifted one group of data instance, and the water yield is 2 liters/minute, and entering the mouth from the beginning, water temperature is 21 ℃, the outlet water temperature is 44 ℃, and 2 minutes gas consumption amount is 34 liters, and temperature is 20 ℃, the pressure of coal gas is near atmospheric pressure, and the low heat value of coal gas is 3400 a kilocalories/standard cubic meter coal gas.Calculate by normal conditions, the result is as follows:

Gas consumption amount V _Standard=V (PT standard)/(P standard T)=1.02 (1 * 273)/(1 * 293)=0.95

(standard cubic meter/hour)

Heat Q=2 * 60 * 1 * (44-21)=2760(kilocalorie that water obtains/hour)

The above-mentioned η value of thermal efficiency ratio that thermal efficiency η=2760/ (3400 * 0.95) ≈ 85% tests sometimes is also high.0.7 millimeter galvanized iron sheet of above-mentioned experimental prototype system's employing is made about 0.35 square metre of heat transfer area.If experimental prototype is made of copper sheet, effect can be better.

This water heater can be divided into two types basically, and a kind of tube central authorities are provided with all kinds heat exchanger plates that polylith has certain inclined plane in order jacket outside cylinder to be arranged, perforate in the middle of the heat exchanger plates that has, and the size of perforate is decided according to gas quantity; Another kind of for there not being jacket outside cylinder, only by about the alternate all kinds heat exchanger plates of using with constitute.As have only one to three heat exchanger plates, experimental result shows that the thermal efficiency is also quite high.

Advantage of the present utility model is as follows:

1, this water heater does not have valve member without electromechanical power, and is simple in structure, and handling ease is extensive with material, and volume is little, and is in light weight, low price, but the punch forming batch process is easy and simple to handle, and water heater can be mixed the fixing use of pipe, and also available sebific duct links temporarily;

2, this water heater is rational in infrastructure, and the steam two-phase is fully disturbance in flow process, and the heat transfer distance is long, fully contact with heat-transfer area, thereby heat-transfer effect is good.Jacket outside cylinder not only rises the cold water of coming in and gives heat effect, and the high-temperature gas of tube central authorities is played insulation effect, thereby heat loss is little, thermal efficiency height.The condensed water that dewfall goes out on heat-transfer area owing to taked measure from structure, flows out outside the device, does not influence flame burning, can not stamp out the flames, thereby the long-time continuous use, safe and reliable;

3, this water heater is not subjected to the restriction of inlet water temperature, and the temperature of water outlet water consumption or coal gas amount is as required regulated.This water heater also can be used as boiler and uses, two water heater series connection and with more effective.This water heater is not subjected to the restriction of fuel type.

Claims (1)

1, a kind of gas instantaneous water heater is characterized in that its plate face of heat exchanger plates and horizontal plane that this water heater and gas stove flame directly contact hold the taper inclination angle; Water heater is by taper shape, and truncated cone and alternate integral body of formation of using with of heat exchanger plates polylith that helical duct is arranged can also be wholy set in this in outer sleeve.
