Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to an air conditioner, and more particularly to the structure of a switch cover that opens and closes a slide switch for switching between normal operation and operation other than the normal operation.

<Prior art> Figs. 1 to 3 show a switch cover shown in Utility Application No. 176736/1983 filed by the present applicant. In the figures, 1 is the indoor unit of a separate air conditioner. In the main body, 2 is a front panel attached to cover the front surface of the main body 1, and 3 is a side wall forming a part of the main body 1, which is integrally molded with the main body 1. Reference numeral 4 denotes an opening made in the side wall 3 in accordance with the position of the knob 6 of the forced operation switch 5, and a cover 7 for hiding the forced operation switch 5 is attached to this opening. This cover 7 is
It can be opened and closed by rotating around a shaft 10 formed integrally with the main body 1. Reference numeral 8 denotes an electronic printed circuit board, and a forced operation switch 5 is installed on the pattern surface with soldering at a position where the knob 6 is in the opening 4, and a knob at the top for switching between forced operation and normal operation. 6 is attached and is normally set to the normal operation side. Reference numeral 9 is an electrical component box for storing and setting the electronic printed circuit board 8, and other electrical components for controlling the operation of the air conditioner are also installed here. The electrical component box 9 is fixed to the main body 1 with screws or the like.

For example, if the microcomputer or the like breaks down, the cover 7 is opened and the knob 6 of the forced operation switch 5 is operated.

Since the conventional structure is as described above, the cover 7 is not removed from the main body 1 even when the knob 6 of the forced operation switch 5 is operated, so there is no chance of losing the cover 7. Since the operation switch 5 is hidden by the cover 7 and cannot be seen, there is no problem in terms of design, and the practical effect is great.

However, because the conventional model did not have a device that could ensure that the knob 6 of the forced operation switch 5 was set to the normal operation position, if the switch was shipped with the switch cover 7 attached while it was set to the forced operation position, Since the air conditioner is operated without microcomputer control, it becomes impossible to adjust the temperature or air volume, which is mistaken for a defective board, leading to market complaints, and improvements were required.

<Summary of the invention> This invention was made in order to eliminate the drawbacks of the conventional ones as mentioned above.The switch cover has a slide switch knob for switching between normal operation and operations other than normal operation such as forced operation. By providing a storage guide for always setting the switch in the normal operation position, the purpose is to prevent the switch from being set incorrectly and to eliminate the drawbacks of the conventional switch.

<Embodiment of the invention> An embodiment of this invention will be described below with reference to FIGS. 4 to 7. 11 is an integrated air conditioner body adopting this invention, 12 is an operation panel for operating the air conditioner, and 13 is a switch cover made of plastic molded product.In case the electronic printed circuit board 23 equipped with a microcomputer etc. breaks down. Until the electronic printed circuit board 23 is serviced, the electronic circuit section is shortened and the forced operation switch (slide switch) 14, which is used to force the air conditioner to operate, is placed so that it is not normally touched. This is to keep it closed. 15 is forced operation switch 14
This is a knob that operates the . This forced operation switch 14 has three notches, the left side and right side are used when the electronic printed circuit board 23 fails, the left side is for forced cooling operation, the right side is for forced heating operation, and
The notch in the center is the notch in normal operation.

Reference numeral 16 denotes an electrical component box installed on the back side of the operation panel 12, into which an electronic printed circuit board 23 and other electrical components (not shown) are mounted.
The forced operation switch 14 is also attached to the electrical component box 16 with screws or the like. Reference numeral 17 denotes a concave operation section provided on the operation panel 12, which has a shaft 18 for attaching the switch cover 13 and an elongated hole 19 corresponding to the operating distance of the knob 15. On the back side of the switch cover 13, which is a plastic molded product, there is a pair of elastic L-shapes whose tips are positioned so as to face each other in the direction of switching movement of the forced operation switch 14, with an interval between the storage parts 20 of the knobs 15. Member 21
A and 21B are integrally molded. When the switch cover 13 is closed, the pair of L-shaped members 21A and 21B are used to insert the knob 15 of the forced operation switch 14, which is always in the normal operating position, into the storage portion 20 between the ends of both members 21A and 21B. Storage guide 21 that guides the knob 15
It consists of Further, on both ends of the back surface of the switch cover 13, there are approximately C-shaped mounting portions 2 that engage with the shaft 18.
2 are integrally molded.

Next, the installation order will be explained. First, the forced operation switch 14 is attached to the electrical equipment box 16 with screws or the like. At the time of shipment, the knob 15 is set to the center. Next, the operation panel 12 is attached to the electrical component box 16 with screws or the like so as to cover the electrical component box 16. Next, the switch cover 13 is attached by pushing the shaft 18 and the attachment part 22 into engagement using the elasticity of the attachment part 22. After the switch cover 13 is installed, the structure is similar to that shown in FIG.
It can be rotated freely. The completed installation state is as shown in the sectional view of FIG. 6, with the knob 15 passing through the elongated hole 19 and being housed in the storage portion 20 between the L-shaped members 21A and 21B.

In such a configuration, when the switch cover 13 is closed when the knob 15 is close to the left notch (in forced cooling mode) as shown in FIG. When the knob 15 slides in the direction of the arrow and is located at the end of the L-shaped member 21A, the L-shaped member 21A returns to its original position due to its elasticity, and the knob 15 moves to the notch in the center (normal operation state). and is stored in the storage section 20. At this time, the right L-shaped member 21B remains in its original shape from beginning to end, and the knob 15
It acts as a stopper to prevent it from moving too far to the right when it is stored in the storage section 20. Also, when the knob 15 is in the right notch (forced heating operation state), the above operation is reversed left and right, and similarly, the knob 15 is in the center notch (normal operation state). It fits in 20.

The storage guide 21 includes L-shaped members 21A and 21B that forcibly move the knob 15 of the switch 14, which has been switched to forced operation, to the normal operation position.
The elastic force generation range is the knob 15 of the switch 14.
It is sufficient if the configuration is such that the movement range is greater than or equal to the movement range of .

According to this configuration, by providing the storage guide 21 that guides the knob 15, the knob 15
Regardless of the position of the switch cover 13, when the switch cover 13 is closed, the knob 15 is in the center normal operation position, and since the elastic force of the L-shaped members 21A and 21B is utilized, the forced operation switch 14
The knob 15 can be reliably positioned without damaging the switch cover 13 or the switch cover 13. As a result,
A situation where the switch cover 13 is attached and shipped while the switch 14 is set to the forced operation position as in the conventional case does not occur, and the inconvenience that would result in a market complaint can be eliminated.

<Effects of the invention> As explained above, according to the invention, the switch cover is provided with a housing for setting the knob of the slide switch, which switches between normal operation and operations other than normal operation such as forced operation, to the normal operation position at all times. By providing the guide, it is possible to prevent the switch from being set incorrectly, and it is possible to eliminate the inconvenience caused by the switch being incorrectly set at the time of shipping the product. Further, since the elastic force of the substantially L-shaped member is utilized, the switch and the switch cover are not damaged, which is a great practical effect.
