Abstract

PURPOSE:To raise the usability of a controller for a hot water supplying and space heating apparatus by a method in which a water level meter and a water level display lamp are provided in the cistern and the display lamp is lighted, flashed or put out and the controller is operated or stopped according to the water level. CONSTITUTION:When a cistern is filled with water, the voltage of the condenser 35 of the chattering detection circuit 53 of a water level detector is zeroed, a 2- input NAND gate 43 is turned ''H'' state, a transistor 43 is turned ON, and a luminous diode 17 is electrified to light a display lamp. When the water level of the cistern is lowered and chattering phenomenon occurs on the water surface, the condenser 35 is charged. When the threshold voltage of the 2-input NAND gate 36 is exceeded, the NAND gate 36 becomes ''H'' state, a non-stable multi- vibrator circuit 54 is oscillated, the transistor 43 is turned ON, and the display lamp is flashed. The usability of the controller of a water supplying and heating apparatus can be raised.

3, when the circulating water is supplied to the heat exchanger 9 and heated, the hot water is sent to the radiator 16 placed in the room, and the return pipe 1
The circulating water returns to the built-in circulation pump 13 through 4. However, when water is heated, it undergoes thermal expansion, and as a result, the water in the distern tank is drained outside the equipment through the overflow pipe 8. Also, when the equipment stops operating, the circulating water is cooled and flows into the distern tank. The water level will decrease. Even if the equipment is operated again and the circulating water expands, it will not be drained from the overflow pipe. Therefore, unless the water level detector is set in a position where it can detect the low level in the distillation tank, it will operate only due to the difference in water level due to expansion and cooling of the water, which can lead to malfunction. becomes.

Since the position of the water level detector 3 and the reed switch 6 is fixed, the position of the float 1-4 will change with the water level, so if the magnet 5 built in the float 4 also changes, the reed switch will change depending on the water level. The amount of water is measured by opening and closing. The reed switch reed sensor is controlled by control device 1.
When the water level drops, this float type water level detector 3 connected to
Since the flow]・4 responds to even small changes in water level, the reed switch 6 also has to react accordingly, causing a chattering phenomenon in which the contacts open and close, making the device less user-friendly. There is.

At present, the water level detector 3 is detecting the full water level of the tank, so the reed switch 6 is closed. The voltage of the capacitor 3i is approximately 0■. Therefore, since the input connected to the capacitor 35 of the two-man powered NAND gate 36 is in the L (low level) state, the output of the two-man powered NAND gate 37 will be in the state - IH (high level) due to its nature.
Transistor 43 is in an on state.

On the other hand, since the input to the banofer 49 is L, the output is also L. Therefore, current flows through the resistors 46 and 47, turning on the transistor 45. Current flows through relay coil 48a, closing its contact 48b and supplying electricity to control circuit 52.

In addition, electricity flows through the transistor 45, the resistor 44, and the light-emitting diode 17 of the indicator light, and the transistor 45 turns on the indicator light.When the water level in the current sinks and the water surface sways, and the reed switch chatters, the diode is charged to the capacitor through the resistor.

Furthermore, if the water surface fluctuates violently and the float of the water level detector vibrates, causing the reed switch to chatter,
After passing through the diode and resistor, the capacitor is charged,
When the threshold voltage of the 2-man NAND gate 36 is exceeded, the capacitor voltage of the 2-man NAND game h3e becomes (high level), so the unstable multi-by-break circuit oscillates, so the NPN transistor 4ick turns on and off. In order to repeat
It hasn't changed yet.

At this time, if you fill the water tank with water and turn on the power again with the power switch, the flashing will stop and the light will turn on.If you leave it unattended further and the water level in the 7 screen drops, the reed switch of the water level detector will be in the open state. Rude (32+51)
The output of the buffer 49 changes from L to H with a time constant of X50. The reason why the time constant is also increased is to prevent malfunction if the chaffing time is longer than the chuckling time.
