Description

  The present invention relates to a controller device that is installed and used on a wall surface of a room, for example.

In many home appliances such as a floor heater used in a house such as a detached house or a condominium, a controller device is installed on the wall surface of the room, and the operation of the device is controlled by the controller device.
Such a wall-mounted controller device generally has a structure in which a control circuit board is housed in a controller device installed on a wall, like the controller device of a floor heating device disclosed in Patent Document 1. It is used. The controller device often uses a structure in which the operation panel unit is removable from the wall surface by using a structure in which an embedded unit embedded in the wall unit and an operation panel unit exposed in the room are combined. And the maintenance etc. were made easy using the structure where the front side of the circuit board stored in an embedding part is covered with an operation panel part.

In terms of maintainability, when checking the inside of the controller device, the circuit board inside the device and its surroundings are visually observed. Since the cable of the used device extending to the device is connected, once installed on the wall, it is troublesome to remove the controller device from the wall. For this reason, the operation of removing only the operation panel portion and visually observing the inside is adopted to facilitate maintenance.

Then, the see-through cover 23 is detachably supported by the housing portion 6 by fitting the side wall portion 2b to a frame-shaped fitting insertion portion 6b protruding from the front surface of the flange portion 6a. The front wall portion 23a of the see-through cover 23 is formed in a shape that follows the front shape of the display board 20, and covers the liquid crystal display surface 24a on the front surface of the display module portion 24 at the upper portion protruding forward. The flat middle portion covers the control unit 25, a room temperature sensor (not shown), key-on / off switch units 26a to 26j, and indicator light emitting diodes 28a to 28d.

Among these, the see-through cover portion 23c facing the liquid crystal display surface 24a faces the display window 31 (corresponding to the information display window portion of the present application) formed in the upper portion of the surface panel portion 7 facing the same portion, and the display panel portion 15 An information display section 32 for performing temperature setting level display, time display, heater energization display, timer operation display, and the like is formed on the upper side.
The push knob portions 27a to 27j of the key on / off switch portions 26a to 26j are all formed in the panel surface portion below the display window 31 through the through hole 33 formed in the flat portion 23d of the front wall portion 23a. Is inserted into the through hole 34. And the front-end | tip of each push knob part 27a-27j is guide | induced to the operation key part formed with the surface sheet 35 affixed on the front surface of the surface panel part 7 through the through-hole 34, and the said surface sheet 35 is made to operate the operation surface 36. As described above, on the operation surface 36, 2ch operation key portions X and Y required for floor heating operation are formed. For example, temperature setting operation key portions 37a and 37b for adjusting the floor temperature, operation operation key portions 38a and 38b for turning on and off the floor heating operation, timer operation operation key portions 39a and 39b for turning on and off the timer floor heating operation, and timer time setting A timer setting operation key unit 40 for performing time adjustment and a clock operation key unit 41 for adjusting time are formed.

The light is guided. In addition, each part of the surface sheet 35 corresponding to the window parts 38c, 38d, 39c, 39d is opened. Reference numeral 35b in FIG. 3 denotes the opening. In the light guide portion 47, the positions of the light emitting diodes 28a to 28d and the positions of the indicator windows 38c, 38d, 39c, and 39d formed on the operation surface are shifted due to layout restrictions. A structure that can handle the case is used. Specifically, as shown in FIG. 4 and FIG. 5, the light guide portion 47 protrudes from the back surface of the see-through cover 23 (the plate surface on the front board side) toward the light emitting surfaces of the light emitting diodes 28a to 28d, respectively. The incident protrusion 48 having a diameter and a part thereof are wrapped with the incident protrusion 48 so as to face the windows 38c, 38d, 39c, and 39d from the surface of the fluoroscopic cover 23 (the surface of the front panel). A structure in which a narrow projecting portion 49 for light emission protruding in combination is used. As a result, even if the incident side and the emission side are slightly deviated from each other, the light from the light emitting diodes 28a to 28d can be transmitted as long as the incident protrusion 46 and the emission protrusion 47 are partially wrapped. It can be led to the operation surface. In the present embodiment, for example, the emission projection 49 has a shape that fits into the openings of the rectangular windows 38c, 38d, 39c, and 39d.

Reference numeral 7a denotes a second front panel exchangeable with the front panel 7. Specifically, the front surface panel 7a is provided with a laterally opening type door body 50 that covers a front surface of the front surface panel 7a with a different design from the original front surface panel 7, for example, the shape of a button portion. A structure is used, and the structure can be replaced with the front panel 7 according to the product.
Next, the operation will be described. Now, for example, it is assumed that the inside of the controller device 5 needs to be observed due to maintenance or the like.

  At this time, the surface panel portion 7 is removed from the wall surface of the wall portion 3 as shown in FIG. Then, the display board 20 appears. Here, the side exposed to the room (outside) of the display board 20, that is, the plate surface on which various circuits and various switches are mounted is shown in FIG. 6 as a whole (plate surface on the surface panel unit 7 side). Since the cover is covered with the fluoroscopic cover 23, the operator may view the display board 20 inside the housing portion 6 and its periphery (inside the apparatus) through the fluoroscopic cover 23.

Thereby, the inside of the housing part 6 including various circuits and various switches of the surface board 20 can be observed by the fluoroscopic cover 23 without fear of touching the surface board 20.
Therefore, the risk of damaging the display board 20 and the components on the display board 20 when viewing the inside of the apparatus can be reduced, and the inside of the controller apparatus 5 can be observed safely. Moreover, the structure of covering the surface board 20 with the fluoroscopic cover 23 is such that the fluoroscopic cover 23 is simply sandwiched as compared with the conventional configuration in which the surface board 20 is only covered with the surface panel unit 7. Therefore, it is sufficient that the surface panel portion 7 has a structure almost the same as that of the prior art, and therefore, it is not necessary to make the panel portion 7 difficult to mold. Of course, since the initial operability of the surface panel portion 7 is maintained as it is, there is no possibility that the operability of the surface panel portion 7 is lowered. In particular, since the see-through cover 23 has a structure that is supported by the housing portion 6, it can be attached to the front of the surface panel portion 7 without being affected by the surface board 20, and can correspond to any surface board 20. . Moreover, when replacing the surface panel 7a with a different design as shown in FIG. 3 instead of the surface panel 7, the housing portion 6 side including the fluoroscopic cover 23 should be replaced as appropriate without any change. You can also. Thereby, the controller apparatus 5 to which various designs were given can be manufactured easily.

  In addition, the front cover 7 has a simple structure in which the display window 31 is formed by the fluoroscopic cover 23, and information from the liquid crystal display surface 24 a is reduced while reducing the risk of damaging the display module 24 on the display board 20. Can be displayed, and the light guide diode 47 is formed on the fluoroscopic cover 23 itself, and the light emitting diode for indicator is reduced while reducing the risk of damaging the light emitting diodes 28a to 28d on the display board 20. The display board 20 has a simple structure in which light of 28a to 28d can be guided to the front side of the front panel portion 7 and a through hole 33 through which the push knob portions 27a to 27j of the key on / off switch portions 26a to 26j are passed. The key on / off switch units 26a to 26j can be operated while reducing the risk of damaging the key on / off switch units 26a to 28j. Can be, there is an advantage that tends to correspond to the surface board 20 having various functions.

  In particular, the light guide 47 using the incident protrusion 48 and the emission protrusion 49 not only clearly lights and displays the light from the light emitting diodes 28a to 28d on the front panel portion 7, but also is shown in FIG. As long as both of them are wrapped, light is guided through the fluoroscopic cover 23. Therefore, the positional relationship between the light emitting diodes 28a to 28d and the lighting display windows 38c, 38d, 39c, and 39d The degree of freedom is high, and the light from the light emitting diodes 28a to 28d can be guided to the front panel portion 7 even if the positions of the light emitting diodes 28a to 28d are slightly shifted from the display position. That is, there is an advantage that the light guide path can be easily secured even when the light emitting diodes 28a to 28d and the display position cannot be arranged at the same position due to installation restrictions.

  The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. For example, in one embodiment, the structure in which the exposed circuit board is covered with a single fluoroscopic cover is taken as an example. However, the present invention is not limited to this, and the exposed circuit board is covered with a plurality of transparent covers. Also good. Of course, it is not limited to how to cover or cover the fluoroscopic cover. Moreover, in one embodiment, although the example which applied this invention to the controller apparatus of a floor heating apparatus was given, it cannot be overemphasized that this invention may be applied to the controller apparatus of not only this but another apparatus and apparatus.
