Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an air conditioner with a humidifier that can blow humidified air into a room to humidify the room.

[Technical background of the invention and its problems] Ultrasonic humidifiers are known as humidifiers with high humidification efficiency, but so far they have only been commercially available as standalone humidifiers. This ultrasonic humidifier is configured to vibrate water stored in a humidifying tank using a piezoelectric vibrator to atomize the water, and blow out the mist from an outlet. Therefore, most of the blown out mist falls downward due to gravity. For this reason, when a humidifier is used in a low place, the mist reaches the floor without being sufficiently evaporated into the atmosphere and wets the floor, making it impossible to obtain a sufficient humidifying effect.

There is also a known type of ultrasonic humidifier that is fixed to the bottom of the indoor unit of a wall-mounted split type air conditioner and humidifies by discharging mist from a high place. Due to its shape, it has the disadvantage of giving a feeling of pressure to the living space and spoiling the appearance. Furthermore, since humidifiers must always contain water, water is supplied from a water tank, but there is a risk of electrical components leaking when water is supplied, so to ensure safety, electrical components must be completely removed. Processing such as sealing is required, which increases costs.

[Purpose of the invention] This invention was made with attention to the above-mentioned circumstances.The purpose of this invention is to provide an ultrasonic humidifier in the main body of the indoor unit, to make it compact, and to make the ultrasonic oscillator part An object of the present invention is to provide an air conditioner equipped with a humidifier in which air conditioning control is not adversely affected by high frequencies generated by the air conditioner.

[Summary of the idea] An ultrasonic humidifier is installed in the indoor unit of a wall-mounted split type air conditioner, and humidified air is blown from a high place.The electrical components for controlling the humidifier are separated from the electrical components for controlling the air conditioning. The reason is that safety has been improved.

[Embodiment of the invention] This invention will be described below based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 indicates the main body of the indoor unit of the air conditioner. This main body 1 is divided into two parts, front and back, into a rear panel 2 and a front panel 3. The front panel 3 has a fan casing storage section 5 that stores a fan casing 4, and a humidifier storage section that stores an ultrasonic humidifier 6. 7 and an electrical component storage section 9 for storing air conditioning control electrical components 8 are provided. The fan casing storage section 5 and the humidifier storage section 7 are separated by a partition plate 10. In addition, the front panel 3 has a suction port 1.
1 and a heat exchange air outlet 12, a water tank insertion port 13 and a humidified air outlet 14 are provided on the left side, and a display panel 15 and an operation panel 16 are provided on the right side. Furthermore, a heat exchanger 17, a drain pan 18, and a cross-flow fan 19 are provided at the front of the fan casing 4, and the heat exchanger 17 exchanges the indoor air sucked in from the suction port 11 to generate heat. The exchange air is blown into the room from the exchange air outlet 12. Note that 20 is a remote control box.

Further, as shown in FIG. 3, the ultrasonic humidifier 6 is composed of a detachable water supply tank 21 and a humidification tank 22 provided below the water supply tank 21. An air intake port 23 is provided on the side wall of the humidifying tank 22, which faces one end of the cross-flow fan 19 and introduces a portion of the air generated from the cross-flow fan 19 into the humidification tank 22. and
Humidified air is blown out from a humidified air outlet 14 at the front. Furthermore, a humidifier control electrical component 24 having an oscillation circuit constituting an ultrasonic oscillation section is provided at the top of the humidification tank 22, and this includes a piezoelectric vibrator 25 and a water level detection switch 26 provided at the bottom of the humidification tank 22. and are electrically connected via lead wires 25a and 26a. Further, a communication cord 27 is led out from the humidifier control electrical component 24, and this is electrically connected to the air conditioning control electrical component 8 through between the rear panel 3 and the fan casing 4 or through the underside of the drain pan 18. has been done. Therefore, even if high frequency waves are generated from the humidifier control electrical component 24, the humidifier control electrical component 24 is separated from the air conditioning control electrical component 8, so it is shielded and does not cause noise, thereby preventing malfunction.

Also, near the humidified air outlet 14 on the front panel, there is a water supply amount display lamp 2 as shown in FIG.
8 is provided. This water supply amount display lamp 28
is a warning light that lights up in response to a signal from the water level detection switch 26 which is activated when the water in the humidifying tank 22 runs out, and calls the user's attention to refilling the water supply. Furthermore, an air conditioning status display lamp 29 is provided on the display board 15 of the front panel 2 to display the room temperature. are laid out for easy identification.

Next, the operation of the air conditioner with humidifier configured as described above will be explained. For example, when the operation switch of the ultrasonic humidifier 6 is turned on to humidify the room during heating operation, the piezoelectric vibrator 25 causes the water in the humidifying tank 22 to vibrate ultrasonically and atomize it. On the other hand, at this time, since the air from the cross-flow fan 19 is introduced into the humidifying tank 22 from the air intake 23, the mist generated in the humidifying tank 22 is blown out from the humidifying air outlet 14, humidifying the room. I can do it. In this way, ultrasonic humidifier 6
During operation, a high frequency is generated from the humidifier control electrical component 24, but since it is separated from the air conditioning control electrical component 8 on the left and right sides of the indoor unit main body 1, no noise is generated and malfunctions are prevented. can do.

In the above-described embodiment, a water supply amount display lamp 28 is provided near the humidifying air outlet 14, and the water supply amount display lamp 28 is turned on when the water in the humidifying tank 22 runs out. However, the display lamp indicating the ON state of the operation switch of the ultrasonic humidifier 6 may be blinked to warn that the water in the humidifying tank 22 has run out.

[Effects of the invention] As explained above, this invention improves humidification efficiency by installing an ultrasonic humidifier in the indoor unit of the air conditioner and making it possible to blow humidified air from a high place. In addition to being able to
It can be made more compact than conventional separate units. Furthermore, by separately installing an electrical component storage area for storing electrical components for air conditioning control at one end of the indoor unit body and a humidifier storage area at the other end, in other words, by installing the two separately, ultrasonic waves can be Even if high frequency waves are generated from the humidifier, noise will not enter the air conditioning control electrical components, which has the effect of preventing malfunctions.
