Abstract
The utility model relates to a balance safety environment friendly gas water heater, the lower end of a back board (9) is connected to an air inlet pipe (7); an air inlet pipe connector (8) has an air intake grid (5); a water-tank is arranged in a shell and then the upper part thereof is connected to a water outlet burn proof pipe (12), while lower part thereof is connected to a hot-water exit (6). The balance gas water heater requires no AC or a special chemistry, burner of which is air-tight, thus problems as carbon monoxide poisoning, anoxic, gas leakage, burning and electric shocking, etc., are removed; moreover, the gas water heater is low in cost, reliable, safe and favorable to be expended.
Description
Technical field
The utility model belongs to balanced type gas heater technical field.
Background technology
For guaranteeing to use the safety of gas heater, the balanced type water heater obtains application more and more widely; In order to improve its function, the structure of water heater becomes increasingly complex, and for example forces the balanced type water heater to use alternating current, and necessary supporting various electronic protections cause cost very high, have hindered the quick expansion in this water heater market.Applicant's patent " closed safety-type gas heater " (ZL01250371.1) provides a kind of and need not alternating current, also need not the balanced type gas heater of special-purpose chimney exhaust, the more existing balanced type gas heater of its cost of manufacture is much lower, and perfect in shape and function, use relievedly, firmly get the user and like.But the applicant thinks and is necessary its further improvement, continues to reduce manufacturing cost under the prerequisite that keeps its basic function, promotes the use of being more conducive to.
Summary of the invention
The technical problems to be solved in the utility model is further to simplify the structure of balanced type gas heater, and product price is even lower, allow the user spend still less to use more comfortablely, safe, relieved.
The utility model solves the problems of the technologies described above with following technical scheme: the bottom at the backboard 9 of gas heater is connected to air inlet pipe 7.8 li air inlet grill 5 is housed at the air inlet pipe interface.The outlet pipe end of termination heat exchanger on the anti-scald water tank 12 in the gas heater housing, following termination hot water outlet 6.
Balanced type safe environment protection type gas heater of the present utility model advances air in the lower backside of housing, housing top smoke discharging, difference in height from air inlet pipe to the smoke evacuation outlet has enough drafts to fuel gas buring, and the burning required air is from the outdoor burner that enters, guaranteed the burning required air quantity, fuel gas buring is complete, thermal efficiency height, burner is by casing sealing, problems such as anthracemia, anoxic, gas leakage, scald, electric shock can not take place, and water heater is cheap for manufacturing cost, and is safe and reliable, is beneficial to popularization.
Description of drawings
Fig. 1 is that balanced type safe environment protection type gas heater of the present utility model is installed in the scheme of installation on the body of wall 11.Smoke exhaust pipe and air inlet pipe are denoted as 1 and 7 respectively.
Fig. 2 is the installation site schematic diagram of the anti-scald water tank 12 in intake interface 8 on the utility model water heater backboard 9 and the casing.
The specific embodiment
Smoke exhaust pipe interface 2 is positioned at the casing top, fixedlys connected with smoke exhaust pipe 1; Air inlet pipe interface 8 is positioned at the outside, backboard 9 bottoms, fixedlys connected with air inlet pipe 7; Combustion gas knob, water yield knob, hot and cold water switch, flame-observing hole and igniting, alarm lamp etc. are arranged on the machine shell panel 4; Side plate 3 is totally-enclosed.The air inlet pipe interface is interior by the air inlet grill of being made up of the parallel blade of several pieces oblique belows 5.Be positioned at the outlet pipe end of termination heat exchanger on the anti-scald water tank 12 of gas heater housing, connect hot water outlet 6 down.In the anti-scald water tank filter net type blade can be arranged, also can not have.Smoke exhaust pipe 1 and air inlet pipe 7 are all passed fixedly, and the body of wall 11 of gas heater stretches out outdoor.
When gas heater took fire work, outdoor air entered from air inlet pipe and participates in burning in the casing, because air is run into air inlet grill, was drawn towards oblique below and flowed, and had both cooled off the casing lower element, had satisfied the burning needs again.After being heated, cold water transfers to hot water outlet through anti-scald water tank.If common gas heater, as temporarily stopping hot water output, when treating to strike sparks again output hot water, the hot water of output meeting just is overheated, scalds the people easily in the use; And when using gas heater of the present utility model, overheated water enters anti-scald water tank 12 from the outlet pipe of heat exchanger, the water neutralization that overheated water was accumulated in the anti-scald water tank originally reduces temperature with regulating, thereby the water that flows out from hot water outlet is or else overheated boiling hot excessively to constant temperature.
When the smoke exhaust pipe end used " the anti-down blast cap of horizontal tower shape " that the inventor invented (ZL01252649.5), promptly during the anti-down blast cap 10 among the figure, solved the problem that flue gas pours in down a chimney fully, made the user of the utility model balanced type safe environment protection type gas heater not have not have the sorrow of Gu fully.
Claims (3)
1, a kind of balanced type safe environment protection type gas heater has housing, heat exchanger, inlet channel, smoke exhaust pipe and water, gas linked switch etc., it is characterized in that the bottom of the backboard (9) at gas heater is connected to air inlet pipe (7).
2, balanced type safe environment protection type gas heater as claimed in claim 1 is characterized in that in air inlet pipe interface (8) lining air inlet grill (5) being housed.
