The present invention relates to a fuel saver used for communicating between cold and hot air heaters. The wing plate is opened and closed by the operation of a motor in which the opening and closing wing plates of the communication array passage are configured to change polarity by a diode. Two cams with different molds coupled to the rotary shaft of the motor are installed together with the pinion, and the micro switch mounted between the motor anode and the micro switch mounted between the diode and the lamp can be disconnected and connected according to the cam rotation. As a result, the fuel valve connected to the switch is closed to control the burner heating, and the wing plate can be opened and closed safely without any adverse wind effect even when installed at any angle vertically or horizontally. It is easy to use and soft to configure because it consumes less and can be made smaller. It will seek to allow a fuel saving of the group.

Conventionally, in order to control the combustion state of the combustion chamber, the rotating plate is fixed to one side of the central axis of the opening and closing wing plate installed in the communication array passage, and the iron core rod of the solenoid is connected to the spring and the crank by connecting the clink to the rotating plate. The crank rotates the rotating plate to open and close the wing plate of the array passage by the pull-out action of the iron core rod by the electromagnetic force of the solenoid operated according to the detection of calories of the wing, and the wing plate must be supported by the spring force of the iron core rod. If it is not attached in the horizontal state, it is affected by the reverse wind, and the closed state is completely full, and when the heater (burner) is operated, the solenoid must be continuously supplied to the solenoid with the wing plate open. Depending on the size, the wings should also be large. Since the solenoid must also be large, there is a defect such as an enlarged end of the instrument.

The present invention has been devised in order to improve such closed ends and defects and to control the amount of supply of liquid fuel by opening and closing the same as the fuel valve micro switch of the heater so as to save fuel. When described in detail as follows.

Announced to open and close the array passage 2 by 90 degrees with the opening / closing blade plate 3 as the shaft 4 in the arrangement passage 2 of the communication passage 1 used for communicating with the cold and warmer. In the opening and closing blade plate of the cam, two cams 6 and 6 ', which are differently coupled to one end of the shaft 4, are mounted on the same axis as the pinion 5 so as to be rotated together. The pinion (5) is geared by rotation of the motor (M) by being engaged with the gear (5 ') of the reduction gear fixed to the motor (M) shaft and the gear (5') engaged with it so as to decelerate rotation. (5 '), (5 ") and pinion (5) is engaged to rotate the wing plate (3) by 90 degrees to open and close the array passage (2), and micro switch (SW ₁ ), SW _{3 is} connected to the cam 6 and microswitch SW ₂ is connected to the terminals 10, 10 ', and 10 " so as to be connected to the cam 6', respectively. (6), (6 ') rotates the micro switch (SW ₁ ), (SW ₃ ) or micro switch (SW ₂ ), each of which is configured to operate, and the circuit configuration thereof allows AC power to be supplied to the terminal block (T) as shown in FIG. In the (M) circuit, the AC power source is rectified by the rectifying diode D ₃ through the contact 2 and the contact 4 of the terminal block T and the micro contact through the relay contacts RL ₁ and RL ₂ . The switch (SW ₁ ), (SW ₂ ) and diodes (D ₄ ), (D ₅ ) connected to the motor (M), and the fuel valve (GV) and lamp (LED) circuit is connected to the heater (not shown) When the temperature control switch (TS) is operated due to the temperature drop or the temperature rise, the AC rectified voltage is supplied to the relay RY and the relay RY. When the motor (M) is rotated when the motor is rotated, the micro switch (SW ₃ ) by the cam (6 ') that rotates in conjunction with the motor shaft when the motor (M) is rotated Terminal 10 " is connected so that the lamp LED is turned on and the fuel valve GV is opened.

In addition, the micro switches SW ₁ and SW ₂ installed at the anode of the motor M are mounted with diodes D ₄ and D ₅ for changing the polarity of the motor M.

In the drawings, reference numerals C ₁ and C ₂ are capacitors, R ₁ and R ₂ are resistors, and 1 and 3 of the terminal blocks T are contacts.

The present invention configured as described above has the fuel valve (GV) and the temperature control switch (TS) installed in the cold and warmer, the motor (M) is operated in accordance with the operating state of the cold and warmer, the gear (5) installed on the shaft (5). '), (5 ") and pinion (5) in accordance with the rotation of the engagement of the opening pin (3) installed in the shaft (4) on the alignment passage (2) while opening or closing the alignment passage (2) Of micro switches (SW ₁ ), (SW ₂ ), (SW ₃ ) connected to terminals (10) and (10 ') so as to be connected to cams (6) and (6') on the axis (4) line, respectively. By operating the fuel valve (GV) and the temperature control switch (TS) to control the fuel supply is to bring the power effect of the fuel.

In addition, the present invention in the state that the wing plate (3) closes the alignment passage (2), even if the power is turned on as shown in Figure 2 in the state that the + relay to the relay contact (RL ₁ ) + polarity in the state that the micro switch (SW ₂ ) is open Since diode D ₄ is reversed and the circuit is blocked, the motor M is stopped from rotating, and when the temperature control switch TS is ON, the power supplied from B is applied to the terminal block ( It is connected to the contact point 3 through the contact 4 of T) and rectified through the diode D ₁ to supply power to the relay RY so that the relay RY operates.

The operating path at this time is A-terminal break contact (2) -relay (RY), B-terminal break contact (4) -temperature control switch (TS) -contact (3) -diode (D ₁ ), also relay The relay contacts (RL ₁ ) and (RL ₂ ) are connected in the disconnected state by the power supply to (RY), and the polarity of the power supplied to the motor (M) is changed to the micro switch (SW ₁ ). +) Is supplied and (-) is supplied to the micro switch SW ₂ and the power circuit is supplied to the motor M through the diode D ₄ , and the motor M is operated to rotate. Done.

At this time, A-terminal break contact (2) -diode (D ₃ ) -resistance (R ₂ ) -contact (RL ₂ ) -microswitch (SW ₁ ) -motor (M), B-terminal break contact (4) -diode (D ₃ ) -relay contact (RL ₁ ) -diode (D ₄ ), by the shaft of the motor (M) and gears (5 '), (5 ") and pinion (5) The contacts of the micro switches SW ₁ , SW ₂ , and SW ₃ are changed by the cams 6 and 6 'associated with the shaft 4 of the wing plate 3 which rotates in association with each other ( The point of contact change can be made by selecting the positions of the cams 6 and 6 'so that the blade plate 3 is rotated by 90 degrees. The micro switch SW ₁ and SW ₂ change the contact point. When the (+) power supplied through the relay contact (RL ₂ ) is cut off by the diode (D ₅ ), the power supply of the motor (M) is cut off and the rotation of the motor (M) is stopped and the wing plate (3) ) is the state lay open a passage arrangement (2). Therefore, also blocked the contact of the micro switch (SW ₃₎ Standing up, so the indicator lamp (LED) and that the power supply to the fuel valve (GV) opens the fuel valve (GV) is a heater (a burner) operating.

The path at this time is A-fuel valve (GV) micro switch (SW ₃ ) -contact (4) -B, A-point (2) -lamp (LED) -resistance (R ₁ ) -contact (1) -micro switch (SW ₃ ) -Contact (4) -B Also, when the heater (burner) is operated to be sufficiently heated or cooled and the temperature control switch (TS) is operated again to OFF, the relay (RY) power is cut off and ray contact _{(RL 1), (RL 2} ) is because it is blocked from access microswitch (SW ₂₎ to (-) a Motor (M) which has been supplied and stop the supply (+), the microswitch (SW ₂₎ Is rotated and the wing plate (3) connected to the gear (5), (5 ') and pinion (5) installed on the motor (M) shaft is rotated 90 degrees so that the arrangement passage of the communication (1) 2) It is in a state of closing.

At this time, the terminals 10, 10 ', and 10' of the micro switches SW ₁ , SW ₂ , and SW ₃ by cams 6 and 6 'associated with the vane ₃ . ), The contact point is changed, the lamp (LED) is turned off, the fuel valve (GV) is closed and the combustion heater (burner) is stopped.

As such, the present invention allows the open / close wing plate 3 to open and close the array passage 2 so that heat or cold energy existing inside the cold and warm heaters exits through the array passage 2 of the communication 1 or by counter-wind. In addition to preventing the loss, and by simultaneously operating the fuel source fuel valve (GV), the fuel consumption savings of overheating or overcooling the cold and warmers can be saved, resulting in a fuel saving effect. Since the wing plate (3) for opening and closing the array passage (2) is rotated 90 degrees based on the motor (M), the wing plate (3) is smooth even when installed at any angle vertically or horizontally depending on the installation position. In this open state, since there is no power supply to the motor M, power consumption is low, and there is an advantage that a motor M of the same size can be used regardless of whether the array passage 2 is large or small.
