Abstract

The utility model relates to a ventilation automatic controller for a gas water heater, particularly to a safeguard device for the gas water heater, which comprises a casing 1, a fixed handle 4, a wire 3, and a heating tracker 2, wherein, the heating tracker is positioned on the front part of the casing, the electrode of the heating tracker is connected with the wire 3, and the back part of the casing is connected with the fixed handle. A smoke vent arranged on the gas water heater is matched with the ventilation fan of a room for use. When the gas water heater is started in a short time, the heating tracker is heated and closed, causing the ventilation fan to be energized to work and ensuring that the room is continuously filled with fresh air. The utility model can avoid the lack of oxygen in the room and the accumulation of carbon monoxide for preventing injury accidents.

Description

Gas heater ventilation automatic controller

The utility model relates to a kind of safety guard of gas heater, a kind of gas heater ventilation automatic controller.

If gas heater is incomplete combustion in use, the carbonomonoxide concentration in the surrounding air is risen and the oxygen deficiency, can cause human casualty accident when serious.In order to prevent the imperfect combustion of combustion gas, avoid accident to take place, method commonly used at present is to install sniffer on gas heater, detector as two even formulas, ion pin induction type or gas sensor formula, work as incomplete combustion, sniffer measures combustion position when becoming bad, starts a control device automatically, and fuel gas source is cut off.

The purpose of this utility model is to propose the another kind of device that gas heater can be used safely.

This gas heater ventilation automatic controller comprises shell, fixed handle, lead and a hot tracker (thermoswitch).The rear portion of shell links to each other with fixed handle, and hot tracker is positioned at the front portion of shell, and its electrode links to each other with lead.

This gas heater ventilation automatic controller can be installed in the exhaust opening of gas heater, and be used with the ventilation fan in room: the hot tracker of gas heater ventilation automatic controller is in series by lead and ventilation fan, in order to the keying of control ventilation fan.Soon, the hot tracker closure of being heated makes ventilation fan energising work after gas heater starts, and guaranteeing indoorly constantly has fresh air additional.After water heater was closed, hot tracker cooled off gradually, and a few minutes just disconnect excessively, and ventilation fan quits work.So just can guarantee that room air is fresh when gas water heater working, sufficient oxygen is arranged, avoid carbon monoxide to gather.

Accompanying drawing 1 is the structure chart of this gas heater ventilation automatic controller;

Accompanying drawing 2 is for putting the structure chart of frame;

Accompanying drawing 3 is the combined socket and switch assembly;

Accompanying drawing 4 is an electrical schematic diagram.

As shown in Figure 1, hot tracker 2 is equipped with in the front portion of the shell 1 of this gas heater ventilation automatic controller, and it can be the thermoswitch of a bimetal leaf.The rear portion of shell links to each other with fixed handle 4, and fixed handle is used for being attached on the gas heater, can make of the material of heat conductivility difference, and lead 3 is generally duplex wire, penetrates in the shell, links to each other with the electrode of hot tracker.

This gas heater ventilation automatic controller can also comprise as shown in Figure 2 put frame 5, put certain position that frame is used for fixing water heater, fixed handle 4 can be inserted in the slot 6 that put on the frame then, in order to fixing automatic controller.

This gas heater ventilation automatic controller can also have a combined socket and switch assembly 7 shown in Figure 3, is made up of switch 8 and socket 9 two parts.One end of lead 3 links to each other with the combined socket and switch assembly.Be electrically connected principle as shown in Figure 4, the contact of hot tracker 2 be in series with socket 9 again after two electrodes of switch 8 are in parallel, pass through power line 10 then and link to each other with external power.Like this exhaust fan 11 is received on the socket, can realize that the manually and automatically control of exhaust fan is switched: during switch closure, exhaust fan is promptly opened, for manually; Hot tracker worked when switch disconnected, and was in automatic control state.
