Description

[Detailed Description of the Invention] Technical Field This invention relates to an air conditioner, such as a cooling fan or a humidifier, which is equipped with a water tank and can selectively use a cold air or humidifying function or a simple air blowing function.

Purpose of the invention This invention adds a simple air blowing function without cold air or humidification functions to air conditioners such as cooling fans and humidifiers equipped with water tanks.
When performing cold air or humidifying operation, an alarm is activated when the amount of water in the water tank becomes low, and when performing simple air blowing operation, the notification device is disabled regardless of the amount of water.

Example In the figure, 10 is a box body, with an upper outlet 11 at the top of the front, a lower outlet 12 at the bottom, and an intake port 1 at the rear.
It has 3. The upper air outlet 11 includes inside thereof a vertical wind direction changing louver 14 and a left/right wind direction changing louver 16 which is periodically oscillated by a motor 15 . The intake port 13 is covered with an air filter 18 which is removably held by a grid cover 17.

Reference numeral 19 denotes an air blower installed in the upper part of the box body 10, which includes, for example, a cross-flow type fan 21 driven by a motor 20 (FIG. 3) and a fan guide 2.
It consists of 2. A partition plate 23 is installed at a distance from the front wall of the box body 10, and forms a ventilation passage 24 between the partition plate 23 and the front wall. The ventilation passage 24 has an upper air outlet 11 at the upper end and a lower air outlet 12 at the lower end.
, and the outlet of the fan guide 22 at a position facing the upper outlet 11 . 25 is a heater installed in the ventilation passage 24 extending from the discharge port of the fan guide 22 to the lower air outlet 12.

26 is a water tank installed in the lower part of the box body 10. 27 pumps the water in the water tank 26 to the fan 2.
1, e.g. motor 28 (third
It consists of a belt 30 made of a porous filter stretched between rollers 29, 29 driven by a
The lower end of the belt 30 is inserted into water in the water tank 26, and as the belt 30 rotates, the belt 30 is impregnated with water, and the temperature of the air flowing across the belt 30 is lowered or humidified by the heat of vaporization of the water.
As this assisting device, a device that atomizes water using ultrasonic waves or centrifugal force can also be used.

31 is a device that responds to the amount of water in the water tank 26, and as described in detail below, one box-shaped support plate 32
assembled on top. Reference numeral 33 denotes a response lever, which consists of a vertical wall of the support plate 32 and a tongue piece 32 bent from the vertical wall.
a and the other tongue piece 32b is inserted into the hole 33.
a and is supported so as to be movable up and down along the vertical wall, and has a horizontal bent portion 33b at its lower end that is inserted into the lower side of the water tank 26. Reference numeral 34 denotes a response switch that is opened and closed by a sloped portion 33c provided at the upper end of the response lever 33, and is fixed within the support plate 32. In the response lever 33, the horizontal bent portion 33b is biased upwardly by the spring 35 in the direction of pushing up the water tank 26, and when the water tank 26 is full, the response lever 33 descends against the spring 35 due to its weight, and the response switch 3
4 is open, but when the amount of water is less than a predetermined amount, one end of the water tank 26 is lifted and the response switch 34 is closed.

In the electrical circuit diagram of FIG. 3, 36 is a power supply. 37 is a timer. By manually closing contacts a and b, the circuit is continuously energized. By closing contacts a, b, and c, the timer motor TM is also energized and its three contacts are closed after a set time. Open. 38 is a energization indicator lamp for all circuits, 39 is an energization indicator lamp for the heater 25, and 40 is a louver drive motor 15.
41 is a switch that controls stopping of the louver drive motor 15; 42 is a belt drive motor 28;
A switch 43 is a switch that selects the rotational speed of the fan drive motor 20. The switch 40 has a left/right wind direction changing louver 16
is operated beyond the normal swing range by a manual operating device (not shown) to bring it into contact with the adjacent louver.
In other words, when the contact is closed, the contact is switched to the heater 25 side. When the louver 16 is open, the contacts on the motor 15 side are closed. Reference numerals 44 and 45 designate a buzzer and an indicator lamp as notification devices, each of which is connected in series with the response switch 34, and the series circuit thereof is connected in parallel with the belt drive motor 28 and in series with the switch 42.

Now, when the fan 21 is rotated, outside air is sucked in from the intake port 13 and from the upper air outlet 11 through the louver 1.
You can blow the air by following the instructions in 4 and 16. At this time, when the switch 42 is closed and the belt drive motor 28 is connected to the power source, the belt 30 is driven, and as described above, the temperature of the air flow is lowered and cold air can be discharged.

As mentioned above, the upper air outlet 1 is opened by the louver 16.
1 is closed and the switch 40 is switched to the heater 25 side, the air flow sent out from the outlet of the fan guide 22 collides with the louver 16, descends the ventilation passage 24, is warmed by the heater 25, and is heated by the lower outlet 12. It is released as warm air from the
At this time, if the switch 42 is closed and the belt 30 is driven, humidified warm air can be discharged. When releasing cold air or humidified hot air, if there is more than a predetermined amount of water in the water tank 26, the weight of the water causes the response switch 34 to be opened as described above, but when the water becomes low, the response switch 34 is opened. When it is closed, the buzzer 44 and indicator lamp 45 are energized to notify you. The buzzer 44 operates for a certain period of time due to a built-in time limit circuit. When simply blowing air or hot air by opening the switch 42 (that is, without driving the belt 30), the buzzer 44 and indicator lamp 45 are disconnected from the power supply, so the water in the water tank 26 is At the very least, there will be no notification operation.

Effects of the invention As described above, this invention allows switching between cold air or humidification operation and simple ventilation operation by manual operation of the switch, and also reduces the amount of water in the water tank 4a when performing cold air or humidification operation. Since it activates an alarm, you can immediately replenish the water, which is convenient in practice, and the system disables the alarm when simply operating the air blower, so you can operate even when the water level in the water tank is low. It does not cause any hindrance.
