At the same time, in the casing 4, the outside air of the casing 4 flows into the openings 4g and 4g at both side edges of the rear panel 4d by the rotation of the centrifugal fan 11 of the air blowing mechanism 10 to be described later. Next, the air flow is sequentially circulated through the purification filter unit 8 and the humidification filter 3. Thereafter, the air is sent out from the upper portion of the scroll 12 in which the centrifugal fan 11 is housed, and is sent out to the outside of the casing 4 of the air cleaner 1 via the screen 14 and the shutter piece 7.

The purification filter unit 8 is configured such that the pre-filter 8a, the dust collecting screen 8b, and the deodorizing filter 8c are arranged in this order from the rear panel 4d side toward the front panel 4a side.

The pre-filter 8a is used to collect large garbage such as cotton wool. The dust collecting filter 8b is used to collect small particles such as dust, dust and pollen. The deodorizing filter 8c is a chemical substance for adsorbing a source of odor.

The humidifying filter 3 is used to increase the humidity of the circulating air.

The air blowing mechanism 10 is configured to include a centrifugal fan 11 disposed in the scroll 12 and a motor 13 for rotating the centrifugal fan 11.

<front panel 4a>

The front panel 4a of the front surface of the machine body, as shown in Fig. 3, has a glass plate 4a1 that has been reinforced, a frame 4a2 that holds the glass plate 4a1 as a frame of the front panel 4a, and a display unit 4a3, and The panel base 4a4 which serves as a skeleton of the front panel 4a is held by the glass plate 4a1 and the frame 4a2.

On the same plane as the surface of the glass plate 4a1, an operation portion using a touch switch is provided.

As shown in Fig. 1, the front panel 4a is provided on the front surface of the air cleaner 1. Conventionally, in the operation portion disposed on the machine, the fluid can invade from the top to the bottom from the gap between the operation button portion and the seam of the machine casing, and as described above, by having the touch switch The front panel 4a of the operation unit is provided on the front surface of the air cleaner 1 (the operation portion of the touch switch is provided on the front surface of the air cleaner 1), and exhibits an effect that the fluid is hard to enter. In particular, by arranging the display unit 4a3 on the back surface of the seamless glass plate 4a1, it is possible to prevent foreign matter, water, or the like from entering the internal substrate of the display unit 4a3.

<glass plate 4a1>

Further, since the glass plate 4a1 on the surface of the operation portion is a glass surface having a smooth and strong surface, the following effects are obtained, and even if the user wipes with a rag to wipe with water, it is easier to clean and less likely to occur. Immersion and damage to the surface.

Conventionally, the front panel is made of resin, and the main method of improving the design of the decoration is to perform the surface grinding of the mold for the purpose of producing a high-gloss surface with high precision. Moreover, in order to achieve a further high decorative design, a method of post-processing such as painting, plating, etc. on the surface is employed, however, the post-processing is expensive, and the coating of the surface of the molded article is inconsistent (uniformity) Sexuality, the incorporation of foreign matter, etc., can not avoid the bad in the post-processing and it leads to high costs.

By using the tempered glass sheet 4a1 as the front panel 4a, it is possible to simultaneously obtain the beautiful gloss generated by the uniform side of the glass, the uniformity at the time of coating, and the stability of production.

The glass plate 4a1 is coated with a transparent colored coating (coating for translucent coating) on the back surface. Thereby, the light projected on the display unit 4a3 is clearly recognized. Further, when it is not necessary to display the projected light, the illumination can be turned off, and at this time, the appearance of the panel 4a only before the glass coating is presented, and the decorative design property is improved. Further, in addition to the surface contacting the display unit 4a3, the coating material of the concealed light is repeatedly applied thereto so as not to penetrate the structure of the back surface. The coating applied to the back surface of the glass plate 4a1 is a portion that is not irradiated so that the portion of the display operation result is illuminated by the illumination device (LED) from the rear and the appearance of the painted color of the unirradiated portion is not different. To match the operation result of the operation unit shown in the foregoing glass The color of the printed film 4a31 (described later) on the display portion on the front surface of the sheet is subjected to a clear coating without light transmission. In other words, the non-irradiated portion of the display portion on the back surface of the glass plate 4a1 is coated with a light-transmissive color in the same color as the film 4a3. Further, the coating is provided on the back surface except for a very small portion, and the surface of the glass sheet 4a1 that the user touches during operation is a uniform surface having no decorative display, and the front panel 4a is excellent in decorative design. Since the surface of the glass plate 4a1 is a smooth surface of the glass surface, it is not caught when it is cleaned with a rag or the like, and it is easy to clean without unevenness or the like.

Further, a protective film (not shown) is attached to the back surface of the glass plate 4a1. The protective film is protected even when the glass plate 4a1 is subjected to a large impact and the glass is broken or cracked, so that it does not scatter to the surroundings. Moreover, the protective film is applied to the surface of the transparent colored coating. The film has a function of further preventing the internal structure from penetrating and appearing on the back surface of the glass plate 4a1 to impair the appearance.

Further, the short side direction of the display unit 4a3 and the short side direction of the glass plate 4a1 are arranged in an intersecting manner. This is because the deformation of the glass sheet 4a1 is likely to occur in the longitudinal direction when heat treatment is applied to the glass sheet 4a1. That is, in view of this property, a configuration in which the influence of the deformation of the glass plate 4a1 can be suppressed when the display unit 4a3 is provided is employed.

At this time, when the longitudinal direction of the display unit 4a3 is combined along the longitudinal direction of the glass plate 4a1, it is affected by the deformation of the glass plate 4a1, and between the glass plate 4a1 and the detecting portion on the display unit 4a3. It is easy to create gaps, and the static capacitance between the electrodes changes irregularly or A problem that is difficult to change.

Therefore, in the present embodiment, the longitudinal direction of the display unit 4a3 is arranged in a direction crossing the longitudinal direction of the glass sheet 4a1.

<display unit 4a3>

Fig. 4 is an exploded perspective view of the display unit 4a3. The description of the configuration of the display unit 4a3 will be made using Fig. 4 .

The display unit 4a3 includes a printed film 4a31, a light guide plate 4a32, a touch switch substrate 4a33 that detects a change in electrostatic capacitance by an operation portion on the surface of the glass plate 4a1, and a display substrate 4a35 formed thereon. The light shielding plate 4a34 of the light emitted from the illumination means only in the forward direction; the display substrate 4a35 of the control unit of the illumination means (LED) on the substrate is controlled according to the detection result of the detection portion; and the casing 4a36. In addition, the display unit 4a3 is composed of a housing 4a36 that houses the light guide plate 4a32, the touch switch substrate 4a33, the light shielding plate 4a34, and the display substrate 4a35 and adheres to the surface film 4a31, and is an LED on each substrate. Under the illumination, the light penetrates to the front surface of the glass plate 4a1 and emerges.

The printed film 4a31 with the characters and marks vacated is attached to the surface of the display unit 4a3. The printed film 4a31 is attached to the back surface of the glass plate 4a1 with a close contact or a very small gap. Therefore, it is possible to penetrate the glass plate 4a1 and clearly confirm the character display from the front side. That is, it has a high visibility and an outer surface which is excellent in appearance by the flat glass plate 4a1. Front panel 4a. Further, the printing color of the film 4a31 is improved when the glass plate 4a1 is viewed from the front, and the appearance of the front panel 4a is uniform, so that the appearance of the front panel 4a is uniform. Decorative design.

The touch switch substrate 4a33 of the detecting portion for detecting the change in the electrostatic capacitance is also mounted with an LED for the purpose of projecting the position of the detecting portion, and is disposed on the substrate surface of the touch switch substrate 4a33 by adhesion. The light guide plate 4a32 can be clearly projected on the operation portion area on the surface of the glass plate 4a1. Further, the light guide plate 4a32 is also adhered to the film 4a31.

The display substrate 4a35 controls the illumination means (LED) on the substrate according to the detection result of the detection portion of the touch switch substrate 4a33, and then displays the operation state through the glass plate 4a1.

Further, in the case of a machine that performs the state display of the machine in the above operation, if the machine is left after the operation, it is difficult to see the top of the machine, and if it is not close, there is often a case where the operation and the state cannot be confirmed, however, In the present embodiment, the front panel 4a including the display unit 4a3 is disposed on the front side of the air cleaner 1, and the side of the air cleaner 1 is illuminated by LED light to display the state of the machine, even from a distance farther away. The status of the machine can be clearly identified.

Further, the operation determining unit (not shown) includes an oscillating circuit that detects that the signal of the change in electrostatic capacitance between the surface operating portion of the glass plate 4a1 and the touch-control switch substrate 4a33 exceeds a certain threshold value. Perform an operation decision. When the static capacitance of the oscillation circuit changes, the oscillation and amplitude are changed in response to the change in the electrostatic capacitance. Thereby, the output of the determination unit is output The automatic control unit of the switching signal and the on/off signal performs the output of the load drive. Further, the determination unit may not be configured to output an ON/OFF signal because the user simply approaches the surface operation portion of the glass plate 4a1 or the wiping operation of the user.

The surface film 4a31 of the display unit 4a3 is attached to the back surface of the glass plate 4a1 with respect to the surface of the glass plate 4a1, and the surface of the glass plate 4a1 is attached to the surface of the glass plate 4a1, and the LEDs of the display substrate 4a33 and the display substrate 4a35 are illuminated. It is illuminated from the back.

When the finger touches the surface operation portion of the glass plate 4a1, the detecting portion on the touch switch substrate 4a33 senses the electrostatic capacitance between the glass plate 4a1 and the change thereof, and transmits the change to the determination portion. Next, the determination unit determines the value, and when it is determined that the operation is input, the program operation is performed.

When the determination unit determines that the electrostatic capacitance is being input, the buzzer mounted on the display substrate 4a35 emits a notification sound, and the input operation state display portion is blinked to indicate that the operation is switched.

Thereby, the mechanical switch actor that is provided with the micro switch or the like provided on the back surface of the resin button pressing the conventional operation portion and the button position on the operation portion decorative plate can be operated by touch, thereby improving the operation. sense.

The substrate case 4a36 has a convex portion, and the substrate case 4a36 is pressed against the glass plate 4a1 by the elasticity of the convex portion. At the same time, the substrate (the touch switch substrate 4a33 and the display substrate 4a35) located in the substrate housing 4a36 can be pressed toward the glass plate 4a1. Thereby, in contact with the glass plate In the case of the surface operation unit of 4a1, the possibility that the operation unit does not operate can also be reduced.

Further, the air cleaner 1 is used, for example, in comparison with a display unit used in a refrigerator or the like, because the display unit 4a3 is large, and the substrate (the touch switch substrate 4a33 and the display substrate 4a35) disposed at the rear of the display unit 4a3 uses only double The surface substrate may cause the price to become expensive. According to the present embodiment, the touch switch substrate 4a33 uses a double-sided substrate, and the display substrate 4a35 uses a single-sided substrate, so that the price can be lowered. Moreover, both substrates use a single-sided substrate, which can make the price even lower.

The air cleaner 1 described in the present embodiment is a structure in which air is sucked into the body from the back surface of the air cleaner 1 and air is discharged to the outside of the body.

Here, a general air cleaner usually has a decorative panel on the front side of the main body, and air is sucked into the air intake port of the machine from the back side of the decorative panel, so that the sucked air passes through the filter screen in the machine and then discharges the air to the outside of the body. structure. When the air is sucked into the machine from the back surface of the decorative panel, when the touch switch substrate 4a33 and the display substrate 4a35 are disposed on the back surface of the decorative panel, only the substrate housing 4a36 covers the structure of the two substrates, and wiring is inevitably formed. In the case where the opening such as the outlet is pulled, the inhaled wind may be immersed in the inside of the substrate casing 4a36. In order to prevent the above, it is necessary to add a casing covering the upper surface thereof or a seal requiring an opening, etc., and it may be more expensive. More cost is necessary. In the present embodiment, as described above, the back surface of the glass plate 4a1 of the front side decorative panel can be sealed by the structure in which the air is sucked into the body from the back side of the main body of the air cleaner 1. The closed structure can further reduce the possibility that the sucked air flows into the touch switch substrate 4a33 and the display substrate 4a35 on the back surface of the decorative panel.
