Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to an atmospheric-pressure storage firewood water heater suitable for rural areas. Background Art

[0002] With the improvement of people's living standards, electric water heaters have become one of the essential household appliances. Water heaters can bring people a comfortable experience. A water heater refers to a device that can raise the temperature of cold water to hot water within a certain period through various physical principles. According to different principles, water heaters can be divided into electric water heaters, gas water heaters, solar water heaters, etc. Existing water heaters have certain defects when used in rural areas or especially mountainous areas. Among them, the disadvantages of electric water heaters are obvious. Their power consumption is relatively large. Prolonged use will not only increase the household electricity burden. In addition, vulnerable parts such as heating elements inside the electric water heater also need to be replaced regularly, further increasing the maintenance cost. Although gas water heaters have certain safety measures, there is still a risk of gas leakage. In this case, it is extremely easy to cause a fire. Due to prolonged use or improper use, components such as pipes and valves inside the gas water heater may age or be damaged, which also increases safety hazards. In addition, in rural mountainous areas with inconvenient transportation, gas replacement and installation are not convenient. The collection effect of solar water heaters will be greatly affected on rainy or cold days. In addition, solar water heaters are composed of many different components. Prolonged exposure to sunlight will shorten the service life of the water heater, and it is extremely inconvenient to replace parts. Content of the Utility Model

An ash hopper is arranged under the grate. An upper flower plate and a lower flower plate are respectively arranged in the upper and lower parts of the body. A first through hole, a first notch and a smoke outlet are arranged on the upper flower plate. A second through hole, a second notch and a heat exchange diversion hole are arranged on the lower flower plate corresponding to the position of the upper flower plate. A number of water storage inner tank cans are arranged in the body. All the water storage inner tank cans are connected in series through a connecting water pipe through a water inlet and a water outlet and then are respectively connected to a water inlet valve and a water outlet valve. The upper and lower parts of the water storage inner tank cans are fixed in the first through hole and the second through hole. A firewood feeding channel arranged at the top of the body passes through the first notch and the second notch and then extends to the grate. A heat exchange folding baffle wrapping the inner side of the water storage inner tank can is arranged at the corresponding position of the heat exchange diversion hole on the lower flower plate.

[0005] Furthermore, a temperature sensor is provided on the body, and the probe of the temperature sensor is placed inside the water storage inner tank.

[0006] Furthermore, a heat insulation protection grille is provided on the periphery of the body.

[0007] Advantages of the present utility model: Compared with the prior art, 1. When in use, the present utility model is more energy-saving and safe than electric water heaters and gas water heaters, reducing the usage cost; 2.

[0016] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the drawings.

[0017] As shown in the figure, a kind of firewood water heater for atmospheric storage includes a hollow body 1. The body is in a cuboid shape (it can also be in other shapes such as a cylinder). The top of the body is connected with a smoke exhaust pipe 5 through a smoke exhaust pipe connection port 16. A grate 11 and a damper 14 corresponding to the position of the grate are arranged at the lower part of the body. A ash hopper 10 is arranged under the grate. An upper flower plate 6 and a lower flower plate 9 are respectively arranged in the upper and lower parts of the body. A first through hole 23, a first notch 22 and a smoke outlet 7 are arranged on the upper flower plate. The lower flower plate is provided with a second through hole 24, a second notch 25 and a heat exchange diversion hole 13 corresponding to the position of the upper flower plate. A number of water storage inner tank cans 2 (seven in the figure) are arranged in the body. An anti-rust and pressure-resistant film 12 (enamel layer) is arranged inside the water storage inner tank cans. All the water storage inner tank cans are connected in series through a connecting water pipe 20 through a water inlet 3 and a water outlet 4 and then are respectively connected with a water inlet valve 18 and a water outlet valve 19 (a safety relief valve is installed at the water inlet to protect the water storage inner tank cans). The upper and lower parts of the water storage inner tank cans are fixed in the first through hole and the second through hole. A firewood feeding channel 15 arranged at the top of the body passes through the first notch and the second notch and then extends to the grate (a cover plate can be arranged on the opening of the firewood feeding channel). A heat exchange baffle 8 wrapping the inner side of the water storage inner tank cans is arranged at the corresponding position of the heat exchange diversion hole of the lower flower plate. The top and / or of the heat exchange baffle is open to facilitate the discharge of flue gas.

[0018] Preferably, in order to timely master the real-time water temperature of the water storage inner tank cans, a temperature sensor 21 is arranged on the body. The probe of the temperature sensor is placed inside the water storage inner tank cans. When the water temperature of the water storage inner tank cans reaches a certain temperature, firewood is no longer added to control the water temperature.

[0019] Preferably, in order to prevent the human body parts from touching the body during use, a heat insulation protection grille 17 is arranged outside the body.

[0020] Brief description of the working process of the utility model: During use, put firewood into the firewood feeding channel 15 at the top of the body and directly drop it onto the upper part of the grate 11. Then open the damper 14 to ignite the firewood on the upper part of the grate. Adjust the opening degree of the damper to make the firewood burn fully and heat the air. The heated air flows into the gap between each water storage inner tank can 2 and the heat exchange baffle 8 through the heat exchange diversion hole 13 on the lower flower plate 9. The hot air exchanges heat with the cold water in the water storage inner tank cans. The temperature of the cold water in the water storage inner tank cans begins to rise gradually. The probe of the temperature sensor 21 synchronously measures the water temperature in the water storage inner tank cans. By designing the height and area of the heat exchange baffle 8, the water in multiple water storage inner tank cans can be evenly heated and the temperature can rise synchronously. The flue gas generated by the firewood is discharged through the smoke outlet 7 on the upper flower plate 6 and then through the smoke exhaust pipe 5. Connect the water outlet valve to a shower head, a kitchen water pipe, etc. to use. After multiple tests on the physical product, it only takes about 25 minutes to heat the water temperature from 28.4 °C to 80 °C, which is sufficient to ensure the use of 4 - 5 people in an average family.

[0021] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to specific embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of protection of the claims of the present invention.
