Description

[Detailed description of the invention] <Industrial field of application> The present invention provides an air conditioner such as an air conditioner that is connected to a blower such as a fan that is separately added to the air conditioner when the air conditioner is stopped. This invention relates to a control circuit for an air conditioner that supplies power.

<Prior Art> Conventionally, an air conditioner and an electric fan have been used separately and independently to cool a room. Therefore, although there are some air conditioners that have outlets for electric fans, etc. (Japanese Utility Model Publication No. 60-111419), these outlets can only be powered by manual operation of the switch on the remote control unit of the air conditioner. It was just something that was turned on and off.

<Problem that the invention aims to solve> Now, if you set the timer to a desired time and operate the air conditioner for cooling on a tropical summer night, if the outside temperature drops more slowly than expected, the set time may not be enough. Everyone has experienced the timer turning off the air conditioner, disrupting a comfortable night's sleep. In addition, in the conventional air conditioner mentioned above, it is troublesome to have to get up and go to the remote control unit to restart the operation or operate the electric fan. In addition, if the setting time is increased, this problem will disappear, but there is a risk that the room temperature will drop too much in the morning, making you sleep cold, and it will also waste electricity, which is uneconomical.

Therefore, the purpose of this invention is to provide an air conditioner that can supply power to a blower such as an electric fan when the air conditioner stops operating due to the operation of a timer, eliminating the trouble of restarting the air conditioner as in the past, and eliminating the need for continuous operation that causes the user to sleep cold and waste electricity. The purpose of this invention is to provide a control circuit for air conditioners such as dayers.

<Means for Solving the Problems> In order to achieve the above object, the control circuit of the air conditioner of the present invention uses power from the power supply for a set time.
Connecting an outlet to which other equipment can be connected to the b contact of the timer means that supplies power to the air conditioner via the contact, and supplying power to the outlet after the air conditioner has been stopped by the timer means. It is characterized by the fact that it has come to be

<Function> When the time set in the timer of the control circuit elapses, such as when going to bed, the timer means switches from the a contact to the b contact to stop the operation of the air conditioner, and
Begins supplying power from the power source to the outlet via the contacts. Then, for example, an electric fan connected to this outlet is driven by the power supply and sends wind into the room where the air conditioner has stopped cooling, cooling the user and lowering the room temperature. In this way, after the timer operates and the air conditioner stops, the electric fan or the like connected to the outlet is automatically supplied with power and starts operating.

<Example> Hereinafter, the present invention will be explained in detail with reference to the illustrated example.

Fig. 1 is a circuit diagram showing one embodiment of the control circuit of an air conditioner, in which 1 is a power plug, 2 is a main switch interposed in this power plug, 3 is connected in series to this main switch 2, and the switch is connected in series to set the A contact 3c-3a that turns off and on at the same time after the elapse of time
A timer 4 having B contacts 3c-3b is connected to the A contacts 3c-3a side of this timer 3, and stops the operation mode of the air conditioner, blows air,
A changeover switch 5 for switching to cooling is connected to the cooling contact side of the changeover switch 4, and has a first contact 5a-5b that turns on at the set temperature, and a first contact 5a-5b that is connected to the B contact 3c-3b side of the timer 3, and is connected to the above-mentioned B contact 3c-3b side, and is connected to the air conditioner contact side of the changeover switch 4, and is connected to the first contact 5a-5b that turns on at the set temperature.
A thermostat having second contacts 5c-5d that turn on at high temperatures, 6 connected to the second contacts 5c-5b, an outlet for supplying power to the blower, 7 connected to the first contacts 5a-5b. Air conditioner compressor motor, 8
is a fan motor of an air conditioner connected to the ventilation contact side of the changeover switch 4.

Therefore, after the compressor motor 7 and fan motor 8 are stopped by the timer 3,
Power is supplied to the outlet 6 via the thermostat 5.

FIG. 2 is a schematic circuit diagram of an electric fan as another device connected to the outlet 6 of the control circuit shown in FIG. In the figure, 9 is a power plug that is inserted into the outlet 6, 10 is a fan motor of the electric fan, and 11 is a selection switch that is interposed between the power plug and the fan motor and switches the electric fan operating motor to stop, weak wind, or strong wind. It is.

The operation of the control circuit of the air conditioner having the above configuration will be described next.

First, when the main switch 2 is closed and in continuous operation mode, the timer 3 does not work and the A contacts 3c-3a remain closed, and the air conditioner stops, blows air, or The air conditioner is operated. During cooling operation, if the set temperature of the thermostat 5 is, for example, 27°C, the first contacts 5a-5b will close when the room temperature exceeds 27°C, open when the room temperature is below 27°C, and open or close accordingly. The compressor motor starts, stops, and adjusts the room temperature.

Next, main switch 2 is closed when going to bed, etc.
Set timer 3 to 5 hours, for example, and plug in outlet 6.
If you plug in the power plug 9 of the electric fan with the selection switch 11 set to weak air, after 5 hours have passed, the a contacts 3c-3a will open and the power supply to the compressor motor 7 and fan motor 8 will stop, and the air conditioner will turn off. The decisioner stops and at the same time, the b contacts 3c-3b of the timer 3 close. Since the air conditioner is stopped, the room temperature rises due to the influence of the outside temperature, and eventually becomes 1°C higher than the above set temperature28
Exceeds ℃. Then, the second contacts 5c-5d of the thermostat 5 close, and the power plug 1 of the air conditioner is connected to the outlet 6 via the b contacts 3c-3b and the second contacts 5c-5d.
The electric fan connected to this outlet receives power and begins to rotate. When the room temperature drops below 28℃ due to cooling by a fan or a drop in outside temperature, thermostat 5's second
Contacts 5c-5d open and the fan stops. In this way, after timer 3 is activated and the air conditioner stops, the electric fan connected to it automatically turns on and off depending on the room temperature and sends air, so the air conditioner can be used as before. Your sleep will not be disturbed by the heat caused by the suspension of the heater.

In addition, since the outlet 6 is supplied with power only when the compressor motor 7 and fan motor 8 of the air conditioner are stopped, the electric fan connected to the outlet 6 is not operated at the same time as the air conditioner. The power consumption capacity of the harmonizer does not increase. Therefore, there is an advantage that the wiring equipment to the air conditioner does not become large-sized. Furthermore, since the air is not blown by the fan motor 8 of the air conditioner, but by a fan connected to the outlet 6, there is an advantage that the fan can be kept at hand and a cool breeze can be obtained for any time.

In the above embodiment, the thermostat 5 is provided after the timer 3, but it is also possible to omit this and supply power directly to the outlet 6.

<Effects of the invention> As is clear from the above explanation, the control circuit for the air conditioner of the present invention has a timer means (b) that supplies power from the power supply to the air conditioner through the contact point (a) for a set time. An outlet to which other equipment such as an electric fan can be connected is connected to the contact point, and power is supplied to the outlet after the air conditioner has been stopped by a timer means, so it can be used at night during summer, etc. Even if the air conditioner stops cooling due to the operation of the timer, power is automatically supplied to a fan connected to an outlet, eliminating the hassle of restarting the air conditioner, and eliminating the need to run the air conditioner continuously, causing the user to sleep cold and waste energy. , which greatly helps in getting a good night's sleep and saving energy.
