Description

  The present invention relates to a remote control device that is used in a home and remotely controls home appliances, and more particularly to a housing shape and structure of the remote control device.

  Conventionally, a remote control device used in a home is configured by, for example, a remote control transmitter for an air conditioner and a holder, and has a shape shown in a perspective view of FIG. The remote control transmitter 90 is a vertically long rectangular body having a liquid crystal display unit 90a on the front surface. When the remote control transmitter 90 is not used by being placed at hand, it is attached to a holder 91 fixed to a wall (not shown) as shown in FIG. It can be held upright.

  The holder 91 includes a back surface portion 91a fixed to the wall, a saucer portion 91b that receives the lower portion of the remote control transmitter 90, and a holding portion 91c that holds the middle of the remote control transmitter 90 in the vertical direction from the left and right. The remote control transmitter 90 can be taken out from the upper portion of the holder 91 or attached.

In such a remote control transmitter (hereinafter referred to as a remote control), in recent years, in order to make it easy to see the display content of the liquid crystal display unit, the display unit surface on which the liquid crystal display element is arranged and the operation unit surface on which operation keys are arranged A so-called “shaped remote controller” has been proposed which has an angled structure.
FIG. 7 is a cross-sectional view of the remote controller and holder having such a structure. In FIG. 7, reference numeral 71 denotes a substantially box-like lower case made of an insulating resin such as polystyrene or ABS. A portion 71a is provided, and the display portion 80 is bent about 15 degrees from the substantially middle portion of the remote control to the right in FIG.

  Reference numerals 72 and 73 are wiring boards made of paper phenol, epoxy containing glass, etc., and a plurality of wiring patterns (not shown) are formed on the upper and lower surfaces by copper or the like. Arranged in parallel on the bottom surface of the case 71, the wiring boards 72 and 73 are electrically connected by lead wires or the like.

  Reference numeral 74 denotes a liquid crystal display element. Reference numeral 75 denotes an operation body such as silicon rubber. A plurality of dome-shaped operation keys 75a are formed on the upper surface, and a movable contact 75b such as carbon is formed on the lower surface of the operation key 75a. The movable contact 75b is opposed to the plurality of fixed contacts 73a on the upper surface of the wiring board 73 with a predetermined gap therebetween to form a plurality of switch contacts.

  Electronic components such as a light emitting diode 76 and a microcomputer 79 are mounted on the upper and lower surfaces of the wiring boards 72 and 73 so as to transmit a remote control signal. Reference numeral 77 denotes an upper case made of an insulating resin such as polystyrene or ABS. Like the lower case 71, the upper case 77 is bent about 15 degrees from a substantially middle portion, and the display surface of the liquid crystal display element 74 is exposed on the upper surface. An opening is provided, and the light transmissive panel covers the opening.

  A plurality of operation keys 75a protrude upward from a plurality of through holes on the upper surface of the upper case 77, and the upper case 77 covers the upper surface opening of the lower case 71 that houses the wiring boards 72 and 73, the operation body 75, and the like. The remote controller 70 is configured. A portion where a plurality of operation keys 75 a are arranged is an operation unit 82.

  When such a remote controller 70 is used for remote control of an air conditioner, a hot water supply device, etc., as shown in FIG. 7, a rear engaging portion is attached to a holder 81 attached to a side wall such as an indoor wall or a pillar. 71a is locked to a hook-shaped locking portion 81a and is detachably mounted. The remote controller 70 can be used alone or with the remote controller 70 mounted on the holder 81 (see, for example, Patent Document 1). .)

  On the other hand, another shape of the V-shaped remote controller shown in FIG. 8 has been proposed. FIG. 8 is a cross-sectional view showing the remote controller and the holder fixed to the wall. In this remote control, the surface of the display unit 80 on which the liquid crystal display element 74 is arranged and the surface of the operation unit 82 on which the operation keys 75a are arranged are formed at an angle smaller than 180 degrees, that is, the display unit 80 is bent, It is formed in a shape that rises from the surface of the operation unit 82 and has a structure that makes it easy to see the display contents.

The main parts of the remote controller in FIG. 8 are almost the same as the parts in FIG. 7, so the same numbers are given to parts having the same functions, and detailed description is omitted.
The remote controller 70 shown in FIG. 8 includes a case composed of an upper case 77 and a lower case 71, and a plurality of operations including a wiring board 72 on which a liquid crystal display element 74 and a light emitting diode 76 are mounted, and operation keys 75a. A wiring board 73 on which the body 75 is mounted and a dry battery 78 for supplying power to each wiring board are arranged.

  In general, a remote controller that controls an air conditioner has fewer operation keys than a remote controller that operates a video device. Accordingly, when the remote control is viewed from the front, the left and right widths are narrower than the width of the remote control for operating the video equipment. For this reason, the dry battery 78 is placed vertically (the longitudinal direction of the dry battery is arranged in the longitudinal direction of the remote control). There are many. In the example of FIG. 8, the dry batteries 78 are arranged vertically.

  On the other hand, a hole-like engaging portion 71a is provided on the back surface of the lower case 71, and a hook-like engaging portion 81a that engages with the engaging portion 71a is provided on the upper portion of the holder 81 fixed to the wall. The remote controller 70 can be detachably attached to the holder 81.

  In this way, the structure in which the V-shaped remote controller is detachable from the holder is different from the plate-shaped remote controller structure in FIG. 6 and is a V-shaped housing, as shown in FIG. 7 and FIG. In order to improve this as much as possible, a structure in which the casing is thinned, that is, the thickness of the remote controller is made as thin as possible has been adopted.

  FIG. 9 is an explanatory view showing a state where the remote controller 70 of FIG. 8 is held in one hand and operated with one hand. As described above, the thickness of the remote control is thin, and a heavy dry battery is arranged on the front side of the remote control in hand. Then, while holding the remote control with a finger other than the thumb, the operation key 75a is pressed using the thumb to perform remote operation.

  However, in the structure of FIG. 7, the dimension L protruding from the wall when mounted on the holder is large, and since all of the operation part protrudes, it is an obstacle when a person passes by the remote control. There was also a sense of pressure on the design.

  On the other hand, in the structure of FIG. 8 (thin type), the dimension L protruding from the wall when attached to the holder can be reduced to some extent, but there is no room in the remote control, so the hook-like engagement provided in the holder There was a problem that the stop portion 81a could not be enlarged and the locking became unstable. Furthermore, there is a problem that even if the same locking structure as the engaging portion 71a and the locking portion 81a is provided on the back of the operation portion of the remote control, it cannot be provided because there is no space in the remote control.

  Further, as shown in FIG. 9, this thin structure remote control has a remote control that is sandwiched between a finger other than the thumb and the base of the thumb of the hand, so that it is difficult to hold the remote control stably and is heavy. Since a certain dry cell is placed in front (downward when the remote control is set up), the center of gravity is in front, and as shown by the dotted line in FIG. 9, the remote control shakes back and forth each time the operation key is pressed, There was also a problem that it was difficult to operate.

Japanese Patent Laying-Open No. 2005-244554 (page 4-5, FIG. 1)

  The present invention solves the above-described problems, and even when the U-shaped remote control is detachable from the wall holder, the dimension protruding from the wall is reduced and the operability of the remote control alone is improved. An object of the present invention is to provide a housing structure for a remote control.

In order to solve the above-mentioned problems, the present invention includes a remote control transmitter that remotely controls a home appliance and is driven by a dry cell, and a holder to which the remote control transmitter is detachably mounted and fixed to a wall. ,
The remote control transmitter has a display element at the top, a display unit arranged so as to be parallel to the wall when mounted on the holder, an operation key at the bottom, and an operation board unit inside. In the remote control device in which the operation part is arranged with an angle in a cross-sectional shape,

Further, since the thickness is increased by the size of the diameter of the dry battery as compared with the structure of the thin remote controller (FIG. 8), there is a space below the display unit and below the operation unit. For this reason, the holder, the remote control and the locking structure, for example, the hook and the corresponding hole can be enlarged, and the remote control can be securely placed on the holder.

  The invention according to claim 2 can reduce the protruding distance from the wall when placed on a holder fixed on the wall, does not obstruct human traffic, and also reduces the appearance of pressure. be able to.

In the invention according to claim 3, when the remote controller is placed on the holder fixed to the wall, the protruding distance from the wall can be further reduced as compared with the case of claim 2. In addition, when the remote control is used on a desktop, the inclined portion is provided, so that the lower end of the operation unit does not hit the palm, so that it can be operated with an easy posture.
Further, when the remote control is used with one hand, the inclined portion is provided so that the corners and sides of the remote control do not directly hit the palm, so that the operability can be improved.
In addition, the remote control can be recognized thinly by the inclined portion, and the appearance of pressure can be reduced.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings. Note that parts having the same functions as those described in the background art are given the same numbers, and detailed descriptions thereof are omitted.

  A feature of the present invention is that, in a structure in which the U-shaped remote controller is detachable from the wall holder, the dry batteries are arranged on the back surface of the operation unit and in the longitudinal direction of the remote control unit. That is, it is formed at an angle that rises more than a predetermined angle with respect to the surface.

  FIG. 1 is a side sectional view of a remote control 10 according to the present invention. The casing of the remote controller 10 is formed with a lower case 1 and an upper case 2 made of synthetic resin with the opening of each other, and an operation key lid 2 a is disposed on the operation portion 82 of the upper case 2. Yes. On the other hand, a battery lid 1 a is disposed in the lower case 1. Further, on the back surface of the lower case 1, there are provided a first engagement portion 1c and a second engagement portion 1d, each of which is a recess having a rectangular hole.

  Inside the casing of the remote controller 10, a wiring board 72 to which a liquid crystal display element 74 and a light emitting diode 76 are connected and a wiring board 73 having an operation body 75 on which operation keys 75a are formed are arranged. A storage portion 1 b for storing the dry cell 78 is provided below the wiring board 73. A battery lid 1a is disposed at the opening of the storage portion 1b. In the area defined by the wiring board 73, the operation board unit extends from the back surface of the wiring board 73 to the inner surface of the upper case 2 (here, the operation key lid 2a) constituting the outer shell of the remote controller 10. 7 and its thickness is defined as t.

  The casing of the remote controller 10 has a shape in which the display unit 80 on which the liquid crystal display element 74 is arranged and the operation unit 82 on which the operation keys 75a are arranged are bent at an angle of 160 degrees. That is, when the surface of the display unit 80 rises by an angle θ = 20 ° with respect to the surface of the operation unit 82 and a person operates the operation key 75a of the operation unit 82, the display on the display unit 80 is displayed. It has a so-called “shaped remote control” shape that makes it easy to see the contents. Note that the surface of the display unit 80 and the surface of the wall 30 shown in FIG. 2 are configured to be substantially parallel.

  On the other hand, as shown in FIG. 1, the operation key cover 2a of the upper case 2 has a structure that can be removed upward, and when the operation key cover 2a is removed, a small operation key 75a that is not normally used appears. Yes. Further, the surface of the operation key lid 2a is inclined downward as it goes to the right in FIG. 1, and an inclined portion 2b is formed. With reference to the plane of the operation unit 82, the inclination angle θ is formed at 20 °, which is the same as the inclination angle θ of the surface of the display unit 80.

Next, a structure in which the remote controller 10 described in FIG. 1 is installed in a so-called “wall-mounted remote controller” using the holder 20 will be described using the cross-sectional view of FIG.
The holder 20 fixed to the wall 30 is made of synthetic resin, and includes a mounting portion 21 corresponding to the back surface of the lower case 1 and a reinforcing portion 22 extending from the lower portion of the mounting portion 21 toward the wall 30. It is configured.

  Above the surface of the mounting portion 21 is a hook-shaped locking portion 21 a corresponding to the hole of the first engaging portion 1 c of the lower case 1, and at the center of the surface of the mounting portion 21 is the second of the lower case 1. A hook-shaped engaging portion 21b corresponding to the hole of the engaging portion 1d is provided, and the remote controller 10 can be attached to and detached from the holder 20 by inserting each engaging portion into each engaging portion. It comes to wear.

Next, the reason why the structure L of the present invention installed as a “wall-mounted remote controller” has a smaller dimension L protruding from the wall than the structure of the thin remote controller shown in FIG. 8 will be described with reference to FIG.
Since the variation factor of the dimension L due to the difference in structure is mainly determined by the dry battery 78, in order to simplify the comparison, the storage position of the dry battery 78 and the direction perpendicular to the wall 30 by the dry battery 78 at the storage position (see FIG. Let us compare the protrusion dimensions in the left direction in FIG.

  In the case of the structure of the present invention, since the dry battery 78 is disposed under the wiring board 73, the thickness is increased by the dimension of the thickness t of the operation board unit 7 as compared with FIG. On the other hand, in the case of the structure of FIG. 8, since the dry battery 78 is arranged with the end of the wiring board 73 as the base end, the thickness of the remote battery 78 does not increase compared to the structure of FIG. Only the length is getting longer. Therefore, if the remote control has a plate-like structure as shown in FIG. 6, the thickness of the dry battery 78 is increased by the dimension d of the dry battery 78 in the structure of the present invention. Absent.

However, since the present invention has the shape of a “V-shaped remote controller”, the increase in the thickness of the remote controller by placing the dry battery 78 under the wiring board 73 is generally the angle θ and the diameter d of the dry battery 78. Determined by That is, the distance L1, which is an increase in the thickness of the remote controller, is determined by the following equation.
L1 = d · cos θ Equation 1

On the other hand, the structure of FIG. 8 is longer than the structure of FIG. 2 by the length l of the dry battery 78, and therefore the increase in the distance L2 due to this structure is determined by the angle θ and the length l of the dry battery 78. That is, it is determined by the following equation.
L2 = l · sin θ (2)

However, L1 in Formula 1 is calculated when the diameter d of the dry battery 78 is simply increased, that is, when the thickness t of the operation board unit 7 is t = d or t> d. The range in which the present invention has an effect in this case is expressed as follows.
d · cos θ <l · sin θ Equation 3

On the other hand, when the thickness t of the operation board unit described in this embodiment is included in the dimension of the diameter d of the dry battery 78 as shown in FIG. 8, the dimension of t is the actual dry battery 78 in the present embodiment. This is an increase in thickness due to. Therefore, the range in which the present invention is effective when t <d is expressed by the following formula.
t · cos θ <l · sin θ (4)

Further, when t = d or t> d, the branch point at which the presence or absence of the effect of the present invention is determined is determined by the following equation.
d · cos θ = l · sin θ Equation 5
Further, when t <d, the branch point at which the presence or absence of the effect of the present invention is divided is determined by the following equation.
t · cos θ = l · sin θ Equation 6

  Here, when t> d, that is, when the thickness of the operation substrate unit 7 is larger than the diameter dimension of the dry cell 78 and the dry cell 78 is a single type dry cell, d = 10.5 mm, l = 44. Since it is 5 mm, the angle θ, which is a branching point for the presence or absence of an effect, is calculated by substituting into Equation 5, and θ = 13.2 °. Similarly, if the dry cell 78 is an AA type dry cell, d = 14.5 mm and l = 50.5 mm. Therefore, when the angle θ is calculated by substituting into Equation 5, θ = 16.1 °. Therefore, it can be seen that the dry batteries of each size are effective when the angle is larger than the calculated angle of θ.

  In the case of the present embodiment, θ = 20 °. Therefore, even if the thickness of the operation substrate unit 7 is larger than the diameter dimension of the dry battery 78, and a single AA or AAA dry battery is used, FIG. The dimension L protruding from the wall is smaller than that of the thin remote controller. Further, if θ is increased, the dimension L can be further reduced.

Further, as in the structure of the thin remote controller in FIG. 8, when the thickness t of the operation board unit 7 described in the present embodiment is included in the dimension of the diameter d of the dry battery 78, that is, when t <d. Will be explained.
For example, assuming that the angle θ is determined by design and θ = 9 °, and that a AAA type battery is used, the thickness of the operation board unit in which the effect of the present invention is effective by substituting the angle θ into the equation 6 The branch point of t is calculated. As a result, when the thickness of the operation substrate unit 7 is about t = 7.1 mm, the effect becomes a branch point. By designing so that t is smaller than 7.1 mm, the operation board unit 7 protrudes from the wall as compared with the structure of FIG. The dimension L can be reduced.

In addition, when the dry battery 78 is not placed vertically but horizontally, the length l of the dry battery may be replaced by the following formula. N represents the number of dry batteries.
l = N · d Equation 7
Naturally, when N = 1, the effect of the present invention cannot be obtained. If the number is other than this, the effect can be obtained, but the effect is small as compared with the case where the dry battery 78 is placed vertically.

  In this way, by placing the batteries vertically under the operation unit 82, the dimension L protruding from the wall when installed as a “wall-mounted remote control” can be reduced, and a person passes by the remote control. It does not get in the way, and it can reduce the feeling of pressure in terms of design. Further, since the inclined portion 2b is provided by cutting the side in front of the operation portion 82 of the remote controller by the angle θ, the dimension L can be further reduced.

  Furthermore, in the present invention, the thickness is increased by the thickness of the operation board unit 7 or the diameter of the dry battery as compared with the structure of FIG. There is space in the part. For this reason, compared with the structure of FIG. 8, the hook-shaped locking portion 21 a and the hook-shaped locking portion 21 b of the holder 20 can be enlarged, and the remote controller 10 can be reliably placed on the holder 20. .

  Next, another effect of the inclined portion 2b provided on the upper case 2 of the remote controller will be described with reference to FIGS. FIG. 3A is an explanatory diagram illustrating a state where the remote controller is placed on the table and operated, and FIG. 3B is an explanatory diagram illustrating a state where the remote controller is operated with one hand held.

  When operating on a desktop as shown in FIG. 3A, the display contents are easy to see because the display unit is raised. In this case, the operation mode is such that the thumb is lightly applied to the side of the remote controller and the operation key is pressed with the index finger. At this time, since the base of the thumb does not hit the inclined portion 2b, the remote controller can be operated comfortably.

  Further, when the remote controller is operated with one hand as shown in FIG. 3B, the remote controller is grasped with four fingers other than the thumb and the base of the thumb, and the operation key is pressed with the thumb. In the case of the present invention, since the dry batteries 78 are arranged vertically below the operation unit 82, the entire remote control is thick and very easy to grip. In addition, a relatively heavy dry battery 78 is disposed near the center of the hand, and therefore the center of gravity is also near the center of the hand. Therefore, even when the operation key is pressed with the thumb, as described with reference to FIG.

4A and 4B are diagrams for explaining the visual perception by the human eye. FIG. 4A shows a case where the inclined portion 2b is not provided, and FIG. 4B shows a case where the inclined portion 2b is provided.
When the inclined portion 2b in FIG. 4A is not present, the side of the end portion in front of the remote control can be clearly seen by human eyes, so that the thickness of the remote control is recognized as it is. However, when the inclined portion 2b is provided as shown in FIG. 4 (B), the side of the end of the inclined portion 2b of the remote control is consciously seen by human eyes, and the thickness of the remote control is felt thin, A feeling of pressure can be reduced.

  Next, another embodiment of the present invention will be described with reference to the perspective view of the remote controller and holder in FIG. Note that components having the same functions as those in the first embodiment are given the same numbers, and detailed description thereof is omitted.

  The remote controller 40 has substantially the same structure as the remote controller of the first embodiment, but the lower case does not include the first engagement portion and the second engagement portion, and the holder 50 also has a hook-like engagement portion. And a hook-shaped locking portion are not provided. Instead, a vertically long groove 40a is provided on the left and right side surfaces of the display unit 80, and a horizontally long groove 40b is provided in front of the lower case.

  On the other hand, the holder 50 is provided with a placement portion 50a corresponding to the lower case, and guide plates 50b are provided on the left and right of the placement portion 50a corresponding to the display portion 80 of the remote controller 40. A vertically long claw 50c corresponding to the groove 40a of the remote controller 40 is provided on the inner surface of the plate 50b. A horizontally long claw 50d corresponding to the groove 40b of the remote controller 40 is provided below the placement portion 50a.

  When the remote controller 40 is placed on the placement portion 50a, the groove 40a of the remote controller 40 and the claw 50c of the holder 50 are fitted, and the groove 40b of the remote controller 40 and the claw 50d of the holder 50 are fitted, so Can be securely held in the holder 50.

  Further, since the inclined portion 40c of the remote controller 40 is formed with a gentle curve, the visual thickness of the remote controller can be reduced and the remote controller 40 can appear thin. Further, when the remote control is operated by hand, since the inclined portion 40c has no corners, it can fit in the hand and improve the operational feeling.
