Description

Indoor unit of air conditioner using photocell

The present invention relates to an indoor unit of an air conditioner which can expect power saving effect by supplying power to a display unit using photovoltaic cells or supplying standby power to an indoor unit in a standby mode.

The indoor unit of a conventional air conditioner includes a base, a cabinet disposed above the base, a front inner panel disposed above the front of the cabinet, a suction panel disposed below the front inner panel, and in which air is sucked, and the front inner side. And a front panel disposed in front of the front side of the panel and under the front side.

In addition, the cabinet is equipped with a blower and a heat exchanger, the front panel is provided with a display unit.

The indoor unit of the air conditioner operates the display unit by receiving power from a power unit receiving external power, or supplies standby power to the indoor unit in the standby mode.

In more detail, the air conditioner operates by being divided into a standby mode and an operation mode. Herein, the operation mode is an operation mode in which air conditioning is performed by a user's command. In this case, the driver directly controls the operation of the air conditioner by using a forced operation input unit provided in the air conditioner or uses a remote controller to control the air conditioner. Remote control.

When the air conditioner operates in the operation mode, it naturally consumes power to perform air conditioning. However, when the air conditioner operates in the standby mode, the air conditioner should always wait with the power supplied to receive a command by the remote controller. The power consumed in such a standby state is called standby power. However, there is a problem that power is consumed even in the standby power state.

Similarly, the display of the display portion must be continuously powered in both the operation mode and the standby mode.

And a blower motor connected to the shaft, and an orifice 62 mounted to the front of the fan housing.

The front surface of the blower 60 is equipped with a photocatalyst plasma air purifier 70 for purifying the air sucked into the blower 60.

The photocatalyst plasma air purifier 70 ionizes dust in the air by discharging and irradiates light energy, an ion collecting unit for collecting dust ionized by the ionizing unit, and odor particles are collected and the ionizing unit is ionized. And a photocatalyst filter for decomposing odor particles collected by light energy irradiated from inside the unit, and a high voltage generator for applying a high voltage to the dust collecting filter.

Reference numeral 84 is a control box installed in the blower 60 is equipped with electrical components for controlling the operation of the indoor unit.

On the other hand, it is preferable to install a photovoltaic cell 45c on the front panel 40 or the display unit 45 as shown in FIG.

For example, the photovoltaic cell 45c may be provided in the display unit 45 so that it is easy to be exposed to the outside, so that light is smoothly supplied, the circuit connection is easy, and the appearance is preferable.

The photovoltaic cell 45c is a battery that converts light emitted from the indoor lighting into electricity, and a circuit for supplying power to the standby power of the display unit 45 or the indoor unit is connected.

That is, when the photovoltaic cell 45c is installed in the display unit 45, a circuit can be directly connected to the display 45a and the PCB 45b of the display unit 45.

When the photovoltaic cell 45c is installed on the front panel 40, the irradiation rate may be higher because it is disposed closest to the room, but a circuit must be disposed in the interior of the front panel 40 to be connected to the PCB 45b.

In this way, the power supply of the photovoltaic cell 45c is supplied to the illumination for the display 45a of the display unit 45, so that a power saving effect can be expected.

In addition, the photovoltaic cell 45c can expect a power saving effect by supplying power to a power source for maintaining the standby mode in the standby mode in which the outdoor unit is turned off and only the indoor unit is turned on.

Since the photovoltaic cell 45c flows in direct current, an inverter (DC-> AC) is preferably installed in order to apply to alternating current of general household appliances.

Looking at the operation of the present invention configured as described above are as follows.

First, when the indoor unit of the air conditioner receives a cooling / heating operation command, the first inlet panel 4 is rotated by a motor to open the suction guide part 3, and the second and third parts are operated. Inlet panels 31 and 37 are rotated by a motor to open each of the air inlet ports 30a and 36a, and each of the first and second discharge port panels 24 and 25 is rotated by a motor to Each of the side air outlets 21 and 22 is opened, and the blower motor is driven to rotate the blower fan.

When the blowing fan is rotated, air outside the indoor unit of the air conditioner is sucked into the indoor unit of the air conditioner through the suction guide part 3 and the air suction ports 30a and 36a.

The air sucked through the suction guide part 3 is guided to the upper side of the base 2 and then passes through the first filter 6, the second filter 7, and the third filter 8 in order. The air sucked through the air inlets 30a and 36a is purified while passing through the fourth and fifth filters 33 and 39.

The purified air as described above is pumped to the front of the blower 60, passes through the photocatalyst plasma air purifier 70, passes through the orifice 62 and the fan housing 61, the upper side of the blower 60 Is blown into.

Then, it is heated or cooled while passing through the heat exchanger 50, and is discharged to the side air outlets 21 and 22.

On the other hand, when the indoor unit of the air conditioner receives an operation command for purifying the air, the first intake port panel 4 is rotated by a motor to open the intake guide part 3, and the second and third intake ports. Each of the panels 31 and 37 are reversely rotated by a motor to seal each of the air intake ports 30a and 36a, and to open each of the first and second discharge port panels 24 and 25, The blower motor is driven to rotate the blower fan, and a high voltage is applied to the photocatalyst plasma air purifier 70.

When the blowing fan is rotated, air outside the indoor unit of the air conditioner is sucked into the indoor unit of the air conditioner through the suction guide part 3, and the sucked air is guided to the upper side of the base 2. After passing through the first filter (6), second filter (7) and third filter (8) in order to purify and then forwarded to the front of the blower (60) to pass through the photocatalyst plasma air purifier (70) do.

The air passing through the photocatalyst plasma air purifier 70 is ionized and collected in the air, and odor particles are collected and purified again, and passed through the orifice 62 and the fan housing 61 to pass the blower ( 60 is blown to the upper side, and after passing through the heat exchanger 50 is concentrated through the side air discharge port 21, 22 to the outside of the indoor unit of the air conditioner.

Meanwhile, the indoor unit of the air conditioner disassembles the front panel 40, replaces the color panel 42 with a new color panel, and assembles the front panel 40. Easily changed.

In addition, when the first, second, third, fourth, fifth filter (6) (7) (8) (33) (39) is to be cleaned or replaced, the front panel (40) fixed by hanging is removed. The front part 20c of the front inner side panel 20 and the front lower side of the front part 20c are opened, and the first, second, third, fourth and fifth filters 6, 7, 8 and 33 are opened. (39) is easy to withdraw to the front side so that the first, second, third, fourth, fifth filter (6) (7) (8) (33) (39) can be easily cleaned or replaced.

The indoor unit of the air conditioner according to the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

For example, after charging electrical energy of a photovoltaic cell to a storage battery, the electrical energy of the charged storage battery may be supplied to a display unit or a standby power source.

The present invention can also be applied to an outdoor unit of an air conditioner.
