Abstract
The utility model discloses a gas water heater. A water heater main-body formed by ignition, controlling and burning devices which are similar with that of the prior gas water heater is arranged in a casing, and a smoke-venting pipe connected with the main body is also arranged. The utility model is characterized in that the casing body is a sealed structure, and a gas-feeding pipe is connected with the lower part of the casing body and the nozzle of the gas-feeding pipe can be extended to the outside of a wall, so the gas is burnt in the sealed casing-body for the water heater of the utility model and the air required by the burning is imported through the gas-feeding pipe from the outside of the wall. So, even the utility model is arranged in a bath room, the oxygen-lack or poisoning of carbon monoxide and carbon dioxide happened to the people in bath can be avoided. And the burning of gas is stable and complete, so the temperature of the hot water can be guaranteed, and the gas-using rate can be raised.
Description
Affiliated technical field
The utility model relates to a kind of gas heater.
Background technology
At present, the gas heater of hot water is provided for bathing, generally all be installed between indoor non-bathing or two places between bathing, the air of its burning usefulness all is to be provided by the air admission hole below the water heater housing, on the water heater housing, have glory hole, also have flue gas in its both sides and help gas hole etc.If this water heater is installed between non-bathing, regulate firepower and water temperature inconvenience, and hot-water line need pass wall, hot-water line is longer, and thermal losses is big.If this water heater is installed in the bathroom, the whole of fuel gas buring use are the interior air of bathroom, bathing time length can cause the bathroom anoxic, or carbon monoxide, CO 2 waste gas excessive concentration etc., serious meeting causes the bathing people because of anoxic or carbon monoxide, the phenomenon of harm such as CO 2 waste gas health takes place, in addition, prolongation along with the bathing time, water vapor concentration between bathing increases, the air that is rich in steam enters the combustion chamber, can make fuel gas buring unstable and not thorough, so just cause hot water temperature's instability, reduce the efficiency of combustion of combustion gas simultaneously.
The utility model content
The purpose of this utility model provides a kind ofly utilizes outdoor air burning and water heater to be installed in not to be subjected to again in the bathroom that steam influences gas heater easy to use in the bathroom.
For achieving the above object, the utility model gas heater includes the water heater main body of being made up of water heater housing, the electronic ignition device of installing, control device and burner etc. in housing, the water inlet pipe, outlet pipe and the Gas Pipe that are connected with the water heater main body, and the smoke exhaust pipe that is connected with water heater main body top etc., the water heater housing is a hermetically-sealed construction, is connected with air inlet pipe on housing.
Above-mentioned gas heater is connected with air inlet pipe in the water heater lower part of frame.
Above-mentioned gas heater, its smoke exhaust pipe and air inlet pipe are concentric tube.
Because the utility model gas heater housing is a hermetically-sealed construction, be connected with air inlet pipe in lower part of frame, the mouth of pipe of this air inlet pipe can reach outside the wall, so the combustion gas of the utility model water heater is the water heater housing internal combustion in sealing, and the air of its burning usefulness is introduced outside wall by air inlet pipe, even the utility model water heater is installed between bathing, during use, burning does not consume the air between bathing on the one hand, or carbon monoxide, CO 2 waste gas does not enter between bathing, thereby reduces even stopped bathing people anoxic or carbon monoxide, phenomenons such as CO 2 waste gas poisoning take place; Steam on the other hand between bathing can't enter in the water heater housing, thereby has guaranteed the flameholding of combustion gas, that is to say the abundant burning of the stable and combustion gas that has guaranteed the hot water temperature, has improved the utilization rate of combustion gas; Can regulate firepower and water temperature by the firepower and the water yield by-pass cock of direct adjusting water heater besides, easy to use.
Description of drawings
Figure 1 shows that the utility model gas heater front view schematic diagram.
Fig. 2 be shown in the another kind of structural representation of blast pipe shown in Figure 1 and air inlet pipe.
1. water heater main body, 2. firepower by-pass cock, 3. flame observation window, 4. smoke exhaust pipe, 5. water yield by-pass cock, 6. air inlet pipe, 7. Gas Pipe, 8. water inlet pipe, 9. outlet pipe, 10. air inlet pipe B, 11. smoke exhaust pipe B.
The specific embodiment
As shown in Figure 1, water heater housing [1] is the box-like structure of a sealing, electronic ignition device, burner and control device etc. are installed within it, firepower by-pass cock [2], water yield by-pass cock [5], water inlet pipe [8], outlet pipe [9], Gas Pipe [7] and smoke exhaust pipe [4] etc. are installed thereon, have flame observation window [3] thereon, this flame observation window [3] is connected with air inlet pipe [6] with the transparent material sealing in its underpart, smoke exhaust pipe [4] and air inlet pipe [6] are all stretched out outside the wall.Electronic ignition device in the utility model gas heater, burner and control device, firepower by-pass cock [2], water yield by-pass cock [5], water inlet pipe [8], outlet pipe [9], Gas Pipe [7] and smoke exhaust pipe [4] etc. are all identical with existing gas heater, its difference is that water heater housing [1] is designed to an enclosed construction, is connected with air inlet pipe [6] in the bottom of water heater housing [1].
As shown in Figure 2, air inlet pipe B[10] and smoke exhaust pipe B[11] be designed to concentric tube, at air inlet pipe B[10] below of end has air admission hole, at this moment, picks out to pipe of outdoor need from the water heater main body, be convenient to install and attractive in appearance.
Claims (3)
1. gas heater, include the water heater main body of forming by water heater housing, the electronic ignition device of in housing, installing, control device and burner etc., the water inlet pipe, outlet pipe and the Gas Pipe that are connected with the water heater main body, and the smoke exhaust pipe that is connected with water heater main body top etc., it is characterized in that: the water heater housing is a hermetically-sealed construction, is connected with air inlet pipe on the water heater housing.
2. gas heater according to claim 1 is characterized in that: be connected with air inlet pipe in the water heater lower part of frame.
