Abstract
The utility model relates to a kind of gas heater Novel down-draught prevention device.Its technical scheme is: when outdoor cold air enters by gas heater exhaust outlet, run into down-draught-proof deep bead and warming plate, because down-draught-proof deep bead has the unidirectional function of passing through, therefore cool exterior air cannot blow into gas heater, and warming plate plays insulation effect to inner air simultaneously.When the temperature sensor in heated at constant temperature parts detects internal temperature lower than temperature control panel design temperature, heated at constant temperature parts automatically start heating tape inner air are heated, and power-off after reaching design temperature.By the water tank that uses this product to prevent that north of china in winter gas heater from causing due to the cold air down draught bursting by freezing of freezing, make the use gas heater that the common people in the winter time can be convenient and safe.
Description
Technical field
The utility model relates to a kind of defroster, particularly a kind of gas fired water heater down-draught-proof defroster.
Background technology
Northern area winter temperature is lower, cold air can enter Water tank for gas water heater top by gas heater blast pipe, when gas heater does not use, will make in water tank water freezing and cause gas heater to use, when serious, in water tank, water freezing expands and will cause water tank spalling to destroy.
Summary of the invention
The purpose of this utility model is the deficiency for existing gas heater, proposes gas heater down-draught-proof defroster in a kind of winter, has the features such as easy for installation, safe and reliable.
Its technical scheme is: a kind of gas fired water heater down-draught-proof defroster, mainly by body (1), warming plate (2), down-draught-proof deep bead (3), heated at constant temperature parts (4), formed, described down-draught-proof deep bead (3) is connected on warming plate (2) by pin, can rotate freely, described warming plate (2) is arranged on body (1) inside, described heated at constant temperature parts (4) are arranged on body (1) outside, down-draught-proof deep bead will stop outside wind to blow into gas heater top because it is unidirectional by function, and warming plate plays insulation effect to inner air simultaneously.Described heated at constant temperature parts (4) are comprised of temperature sensor (4.1), temperature control panel (4.2), heating tape (4.3), power line (4.4), temperature sensor (4.1) is fixed on warming plate (2) through body (1), heating tape (4.3) is wrapped in heated at constant temperature parts (4) inside, temperature control panel (4.2) is embedded in heated at constant temperature parts (4) outside, and power line (4.4) is connected on heated at constant temperature parts (4).When Inside Air Temperature is during lower than temperature control panel (4.2) design temperature, heated at constant temperature parts will make inner heating tape (4.3) energising heat and after reaching design temperature, stop heating inner air tube automatically.By above scheme, guarantee Water tank for gas water heater icing bursting by freezing in the winter time.
Accompanying drawing explanation
Accompanying drawing 1 is overall diagram of the present utility model;
Accompanying drawing 2 is Local maps of the present utility model;
Accompanying drawing 3 is profiles of the present utility model;
Accompanying drawing 4 is heated at constant temperature component diagram of the present utility model;
In upper figure: body 1, warming plate 2, down-draught-proof deep bead 3, heated at constant temperature parts 4, temperature sensor 4.1, temperature control panel 4.2, heating tape 4.3, power line 4.4;
The specific embodiment
1-4 by reference to the accompanying drawings, the utility model will be further described:
The utility model patent is comprised of body 1, warming plate 2, down-draught-proof deep bead 3, heated at constant temperature parts 4, when entering by gas heater exhaust outlet, outdoor cold air runs into down-draught-proof deep bead 3 and warming plate 1, because down-draught-proof deep bead 3 has the unidirectional function of passing through, therefore cool exterior air cannot blow into gas heater, and 1 pair of inner air of warming plate plays insulation effect simultaneously.The temperature that temperature sensor 4.1 in heated at constant temperature parts 4 detects is during lower than 4.2 temperature control panel design temperature, and heated at constant temperature parts 4 automatically start 4.3 pairs of inner airs of heating tapes and heat, power-off after reaching design temperature.
The invention has the beneficial effects as follows: by using the utility model to prevent the icing bursting by freezing of water tank that north of china in winter gas heater causes because cold air is windproof, make the common people can use easily and safely gas heater in the winter time.
Claims (2)
1. a gas fired water heater down-draught-proof defroster, it is characterized in that: mainly by body (1), warming plate (2), down-draught-proof deep bead (3), heated at constant temperature parts (4), formed, described down-draught-proof deep bead (3) is connected on warming plate (2) by pin, can rotate freely, described warming plate (2) is arranged on body (1) inside, described heated at constant temperature parts (4) are arranged on body (1) outside, down-draught-proof deep bead will stop outside wind to blow into gas heater top because it is unidirectional by function, and warming plate plays insulation effect to inner air simultaneously.
2. the antifreeze mechanism of a kind of gas fired water heater down-draught-proof according to claim 1, it is characterized in that: described heated at constant temperature parts (4) are by temperature sensor (4.1), temperature control panel (4.2), heating tape (4.3), power line (4.4) forms, temperature sensor (4.1) is fixed on warming plate (2) through body (1), heating tape (4.3) is wrapped in heated at constant temperature parts (4) inside, temperature control panel (4.2) is embedded in heated at constant temperature parts (4) outside, power line (4.4) is connected on heated at constant temperature parts (4), when Inside Air Temperature is during lower than temperature control panel (4.2) design temperature, heated at constant temperature parts will make inner heating tape (4.3) energising heat and after reaching design temperature, stop heating inner air tube automatically.
