DETAILED DESCRIPTION OF THE INVENTION

[0010] Each of the following is an example of a technique included in this disclosure. [1] An installation method for installing a remote controller for a gas appliance on a wall to be installed, a preparation step of preparing a mounting plate having a fixing plate portion fixed to the wall and a mounting portion integrally formed with the fixing plate portion, and a storage box for storing the gas appliance remote controller; a fixing step of fixing the fixing plate portion to the wall; an attachment step of attaching the gas appliance remote controller to the attachment portion; Including, The preparation step includes: preparing the mounting plate so that the fixing plate portion has an insertion portion configured as a hole or a notch through which an electric wire led out from the wall side passes; preparing the storage box so as to provide a slit for hooking the electric wire in the storage box; Including, The fixing step includes: a step of passing the electric wire led out from the wall side through the insertion portion of the mounting plate prepared in the preparation step; a step of hooking the electric wire into the slit of the container box prepared in the preparation step; Including, The electric wire led out from the wall side is passed through the insertion portion, and the electric wire is hooked in the slit, and in this state, a step of fixing the fixing plate portion to the wall or a step of connecting the electric wire to the remote controller for the gas appliance is performed. How to install a remote controller for gas appliances.

[0011] The gas appliance remote controller installation method of [1] above includes the steps of passing an electric wire drawn from the wall side through an insertion portion of the mounting plate prepared in the preparation step, and hooking the electric wire into a slit in the storage box prepared in the preparation step. When these steps are performed, the drawn electric wire is passed through the insertion portion, and the mounting plate is interposed between the storage box with the electric wire hooked in the slit and the wall. Therefore, even if a worker loses their grip on the electric wire during installation and the electric wire is about to be pulled into the wall, the storage box with the electric wire hooked is likely to get caught near the insertion portion of the mounting plate. This makes it less likely for the electric wire to fall into the wall, making it easier for the worker to install the gas appliance remote controller.

[0012] [2] In the preparation step, the storage box is formed to have a peripheral wall portion that surrounds a storage space that stores the gas appliance remote controller and has one end that forms an opening, a bottom wall portion that closes the other end side of the peripheral wall portion, and a lid portion that opens and closes the opening of the peripheral wall portion, In the hooking step, the electric wire is hooked so as to connect the electric wire to a box body that forms a part or the whole of the storage box and that is formed by integrally connecting the peripheral wall portion, the bottom wall portion, and the lid portion. A method for installing the remote controller for gas appliances described in [1].

[0013] The installation method for the remote controller for gas appliances described above in [2] involves hooking the electric wire so as to connect it to the box body, which is made up of a peripheral wall portion, a bottom wall portion, and a lid portion that are integrally connected, so that after the hooking process, it is unlikely that the hooked part of the electric wire will come out of the insertion portion.

[0014] [3] In the preparation step, the slit is provided on the edge of the container box. A method for installing a remote controller for a gas appliance according to [1] or [2].

[0015] The installation method for the gas appliance remote controller described above in [3] makes it easy to form a slit in the storage box during the preparation process, and during the fixing process, the electric wire can be hooked directly into the slit present on the edge, making it easy to hook the electric wire into the slit.

[0016] [4] In the preparation step, the container is provided so as to have a flap; The slit is provided on the edge of the flap. A method for installing a remote controller for a gas appliance according to any one of [1] to [3].

[0017] In the installation method for the gas appliance remote controller described in [4] above, the slit is provided in the flap, which does not affect the aesthetic appearance, so the provision of the slit does not detract from the aesthetic appearance of the entire container box. In addition, because the slit is provided in the flap, it is unlikely that the presence of the slit will significantly reduce the strength of the outer wall of the container box.

[0018] [5] In the preparation step, a plurality of the slits are provided at intervals in the container box. A method for installing a remote controller for a gas appliance according to any one of [1] to [4].

[0019] The installation method for the gas appliance remote controller described in [5] above makes it easier to hold the wires securely when there are multiple wires because the wires can be separated and hooked into each slit. For example, even if the wire is released from the hold of one slit, the other slits are likely to maintain the hold, making it less likely that all wires will be released.

[0020] [6] An auxiliary tool used in installation work for attaching a mounting plate to a wall, the mounting plate having a fixing plate portion fixed to the wall and a mounting portion integrally formed with the fixing plate portion, and attaching a remote controller for a gas appliance to the mounting portion, a storage box for storing the gas appliance remote controller; the fixing plate portion is provided with an insertion portion configured as a hole portion or a notch portion through which an electric wire led out from the wall side passes, The receiving box is provided with a slit for hanging the electric wire. An auxiliary tool used in the installation of remote controllers for gas appliances.

[0021] The above-mentioned auxiliary device [6] can produce the same effect as the above-mentioned installation method [1].

[0022] First Embodiment The following description relates to the first embodiment. 1. Remote Controller 100 1 shows a gas appliance remote controller 100 and a gas appliance remote controller mounting plate 1 on which the gas appliance remote controller 100 is mounted. Hereinafter, the gas appliance remote controller 100 will also be referred to simply as the remote controller 100. The gas appliance remote controller mounting plate 1 will also be referred to simply as the mounting plate 1.

[0023] 1 is a remote controller used to remotely control a gas appliance such as a water heater, for example. Note that the gas appliance remotely controlled by remote controller 100 may be a gas appliance other than a water heater.

[0024] As shown in Fig. 1, the remote controller 100 includes a display unit 104 having a lamp such as an LED or a 7-segment display unit, and the display unit 104 can perform various lighting and blinking operations, and can display letters, numbers, and other symbols. The remote controller 100 also includes a plurality of operation units 106 such as buttons. Note that the illustration in Fig. 1 omits the surface sheet covering the display unit 104 and operation units 106. In the example in Fig. 1, the operation units 106 are configured as buttons that output a predetermined signal when pressed from the outside.

[0025] As shown in FIGS. 1 and 2 , the remote controller 100 has an outer shell formed by a case 102. The case 102 is box-shaped, and its front surface is provided with a hole used for a display unit 104 and a structure for buttons used for an operation unit 106. As shown in FIG. 2 , the rear surface of the case 102 is provided with multiple holes 108 into which the mounting unit 30 (described later) is inserted. The holes 108 function as mounting receiving portions that are attached to the mounting unit 30, and in a typical example, the holes 108 are attached so that the mounting unit 30 is hooked onto the mounting unit 30 by inserting the mounting unit 30. The rear surface of the remote controller 100 is provided with multiple terminals 110 for connecting electric wires 180 (described later). The terminals 110 are electrically connected to electrical components provided within the remote controller 100, and form part of the electrical circuit of the remote controller 100. In the representative example shown in FIG. 2 etc., the hole 108 is configured as a vertically long hole, and is provided on the rear surface of the case 102 near both the left and right ends so as to be recessed forward.

[0026] 2. Mounting plate The mounting plate 1 shown in FIG. 1 is a plate-shaped component fixed to a target wall W (FIGS. 7, 11, and 12) and is a member for mounting the remote controller 100. The target wall W (FIG. 7, etc.) exemplified in the following description is configured as, for example, a wall that divides a space in a building such as a house or other structure. One side of the wall W is a surface Wb that is configured as the surface on which the mounting plate 1 is mounted. For example, on the surface Wb, the majority of the area covered by the mounting plate 1 is configured as a flat surface, and this flat surface is configured along the vertical direction. For example, the angle between the flat surface and the vertical direction is 10° or less (preferably 5° or less). The wall W is configured as a wall that divides a space Wc on one side from a space on the other side. The space Wc on one side is the space facing the surface Wb, that is, the space on the side where the mounting plate 1 and the remote controller 100 are mounted. The space on the other side is the space facing the back surface of the wall W, opposite the surface Wb. A through-hole portion Wa is provided in the wall W. The through-hole portion Wa is configured to extend over part or all of the thickness of the wall W, and is configured as a hole portion that communicates with the space within the wall W or the space Wd on the other side and the space on the one side.

[0027] With this configuration, as shown in Fig. 7, the worker can guide the electric wire 180 present in the space Wd to pass through the through-hole portion Wa, and can guide a portion of the electric wire 180 to be disposed in the space Wc on the one side. Fig. 7 shows an example in which the worker performs such guidance to arrange the electric wire 180 so that it passes through the through-hole portion Wa and straddles the spaces Wd and Wc, and prepares one end of the electric wire 180 (the end to which the remote controller 100 is connected) to be disposed in the space Wc. However, even if the electric wire 180 can be prepared as shown in Fig. 7, if the portion of the electric wire 180 on the space Wd side is significantly heavier than the portion on the space Wc side and the portion on the space Wc side is not very long, there is a risk that the portion on the space Wd side will pull the portion on the space Wc side and fall into the space Wd. In such a situation, the worker needs to always hold the portion on the space Wc side while connecting the portion on the space Wc side to the remote controller 100. However, if the worker accidentally lets go and releases his / her grip, the electric wire 180 will fall into the space Wd as described above. If this situation occurs, the worker needs to pick up the electric wire 180 from the space Wd side and pass it through the through-hole portion Wa again, as shown in FIG. 7, which deteriorates workability. The technology according to this embodiment can suppress or solve such problems, and details thereof will be described later.

[0028] The mounting plate 1 is made of, for example, a metal material or a resin material and has a plate-like shape. In the representative example shown in Figs. 1 to 4, the mounting plate 1 is formed by subjecting a metal plate to metalworking such as bending. As shown in Fig. 1, the mounting plate 1 includes a fixing plate portion 10 having a plate-like shape and a mounting portion 30 provided integrally with the fixing plate portion 10.

[0029] In the example of FIGS. 1 to 4, the fixing plate 10 is configured as a plate-like portion that is fixed along the wall W (FIGS. 7, 11, and 12) to be attached so as to partially cover the wall W. A majority of the fixing plate 10, more than half of the fixing plate 10, is configured as a flat plate with a predetermined thickness. This flat plate has one side plate surface 10A (the plate surface on the remote controller 100 side) and the other side plate surface 10B (the plate surface on the wall W side) that are both configured as flat surfaces, and these flat surfaces are parallel to each other. As shown in FIGS. 11 and 12, when the fixing plate 10 is fixed to the wall W to be attached (the wall to which the remote controller 100 is attached), it is arranged so as to partially cover the surface Wb of the wall W. In this embodiment, a portion of the rear side plate surface 10B (rear surface) of the fixing plate 10 is arranged so as to be in close contact with the surface Wb of the wall W. As shown in Fig. 2, the plate surface 10B (rear plate surface) is the plate surface on the rear side (rear side) of the "flat plate portion of a predetermined thickness" that forms the majority of the area of ​​the fixed plate portion 10. On the other hand, as shown in Figs. 11 and 12, a part of the plate surface 10A (front side) on the front side of the fixed plate portion 10 is arranged so as to be in close contact with or not in close contact with the back surface of the case 102 of the remote controller 100. The plate surface 10A (front plate surface) is the plate surface on the front side (front side) of the "flat plate portion of a predetermined thickness" that forms the majority of the area of ​​the fixed plate portion 10.

[0030] In the example of FIGS. 1 to 4, the fixing plate 10 is provided with an insertion portion 50 configured as a hole. As shown in FIGS. 7 and 8, the insertion portion 50 functions as a hole through which the electric wire 180 leading out from the wall W passes. Specifically, the insertion portion 50 is configured as a through-hole between the plate surface 10A and the plate surface 10B. As shown in FIGS. 11 and 12, the insertion portion 50 is disposed so as to communicate with a through-hole Wa provided in the wall W when the mounting plate 1 is attached to the wall W. The through-hole Wa is disposed so as to penetrate a part or all of the wall W so as to communicate with a space Wc in front of the wall W and a space Wd in the wall W behind the through-hole Wa. In the installed state shown in FIG. 12, the electric wire 180 is inserted through the through-hole Wa and disposed so as to straddle both the front and rear sides of the through-hole Wa. When arranged as shown in FIGS. 11 and 12, the space Wc on the front side of the mounting plate 1 and the space Wd on the rear side of the through-hole portion Wa communicate with each other via the insertion portion 50 and the through-hole portion Wa.

[0031] 1 is a portion where the remote controller 100 is attached, and is a portion provided integrally with the fixing plate portion 10. Specifically, each of the attachment portions 30 is inserted into each of the holes 108 (see FIG. 2) provided on the back side of the remote controller 100, and is positioned within each of the holes 108 while being hooked onto each of the holes 108 (see FIG. 3).

[0032] In the example of Figures 1 to 4, four mounting portions 30 are provided on the mounting plate 1. Each mounting portion 30 has a protrusion 32 that protrudes forward from the outer edge of the mounting plate 10. In the example of Figures 1 to 4, multiple (specifically, two) protrusions 32 are provided on the outer edge of one left-right side of the mounting plate 10, and multiple (specifically, two) protrusions 32 are provided on the outer edge of the other left-right side of the mounting plate 10. Each protrusion 32 is configured as a plate piece that is bent forward and protrudes from the outer edge of the mounting plate 10. Each protrusion 32 (plate piece) is a vertically elongated plate piece with its thickness direction in the left-right direction.

[0033] The convex portion 32 (plate piece) is provided with a front extension portion 35 that is connected to the fixed plate portion 10 and extends forward, and a protrusion portion 33 that is configured to protrude upward from the front end side of the front extension portion 35. A recess that is recessed downward is formed by the upper end portion of the front extension portion 35, the protrusion portion 33, and the outer edge of the fixed plate portion 10.

[0034] As shown in Fig. 3, the four protrusions 32 (Figs. 1 and 2) are inserted into the four holes 108 (Fig. 2) and the four protrusions 32 are placed so that a portion of each hole 108 is supported by each protrusion 32, thereby determining the relative position of the remote controller 100 in the up-down and left-right directions with respect to the mounting plate 1. Each protrusion 33 is hooked onto the edge of the front end of each hole 108, thereby preventing each protrusion 32 from slipping out of each hole 108. More specifically, the protrusion 33 is positioned so that the vicinity of the upper end of the inner wall of the hole 108 rests on the front extension 35, and the protrusion 33 is positioned in front of the front end portion of the upper end of the inner wall of the hole 108, so that the protrusion 33 is hooked onto the edge of the hole 108 from the front side.

[0035] 3. Assistive Device 3 5 illustrates a storage box 60 that stores the remote controller 100. In this embodiment, the storage box 60 functions as the auxiliary tool 3. The auxiliary tool 3 is a tool for assisting in the installation work of the remote controller 100. The installation work includes the work of attaching the above-mentioned mounting plate 1 to the wall W as shown in FIG. 11 and the work of attaching the remote controller 100 to the mounting portion 30 of the mounting plate 1 attached to the wall W as shown in FIG. 12.

[0036] The storage box 60 is a box that stores the remote controller 100 and protects the remote controller 100 during distribution of the remote controller 100. For example, the storage box 60 is a box in which the remote controller 100 is packed when the remote controller 100 is shipped, and is a box in which the remote controller 100 is packed and transferred to a purchaser of the remote controller 100 when the remote controller 100 is traded. The material of the storage box 60 is not limited, and may be, for example, cardboard, paperboard, or other paper other than cardboard or paperboard. The material of the storage box 60 may also be a material other than paper, such as resin. In a typical example, the storage box 60 is made of cardboard.

[0037] As shown in FIGS. 5 and 6 , the storage box 60 is integrally formed with a box body 60A and a detachable piece 70 that can be detached from the box body 60A. The storage box 60 has a peripheral wall 61 formed by walls 61A, 61B, 61C, and 61D, and a bottom wall 62 connected to the lower end of the peripheral wall 61, forming a box-like shape that is open at the top and can be opened and closed. The peripheral wall 61 surrounds the space that accommodates the remote controller 100 on all four sides. The bottom wall 62 closes one side (the lower end side of the peripheral wall 61) of the space surrounded by the peripheral wall 61 on all four sides. In this way, the box-like portion, whose top end is open and formed by the peripheral wall 61 and bottom wall 62, is closed by a plate-like upper wall 63 that serves as a lid. The upper wall portion 63 is bent from the upper end of the wall portion 61C and connected to the upper end of the wall portion 61C. An insertion portion 65 is provided in the upper wall portion 63 and connected to the end portion opposite the wall portion 61C. The insertion portion 65 is bent from the end of the upper wall portion 63 and can be inserted between the wall portion 61A and the flaps 64A and 64B. The flaps 64A and 64B are foldably connected to the upper ends of the walls 61B and 61D, which are part of the peripheral wall portion 61, respectively.

[0038] In the example of FIG. 6, the flap 64A is connected to the upper end of the wall 61B and is bendable relative to the wall 61B, and is displaceable relative to the wall 61B. The flap 64A is provided with a slit 72 for hooking the electric wire 180. The slit 72 is formed in the edge of the flap 64A opposite to the wall 61B. In FIG. 6, a plurality of slits 72 (two in a typical example) are provided at intervals in the longitudinal direction of the flap 64B. Each slit 72 is provided as a cut in an edge of the flap 64A extending in the longitudinal direction (the edge opposite to the wall 61B) in a direction intersecting the longitudinal direction of the flap 64B (for example, a direction perpendicular to the longitudinal direction). Specifically, the slit 72 is configured as a cut extending from the edge of the flap 64A opposite to the wall 61B toward the wall 61B, but does not reach the wall 61B.

[0039] The slit 72 is a cut made by partially cutting the flap 64A across its entire thickness, allowing for insertion and clamping of a thin object. That is, the slit 72 is formed so as to extend from one side (upper wall 63 side) of the flap 64A (upper surface) to the other side (lower surface). Therefore, a thin or thin object can be clamped in the slit 72 across the one and other sides of the flap 64A. Inside the slit 72, one side of the inner wall (one edge of the cut) and the other side of the inner wall (the other edge of the cut) of the slit 72 are in close contact or face each other at very close distances. The portion of the flap 64A near the slit 72 is capable of slight bending or flexing deformation. When deformation occurs in the portion near the slit 72, a restoring force is generated to return the portion to its natural state as shown in FIG. 6 . Therefore, for example, when a long, thin object is sandwiched between slit 72 so as to slightly deform slit 72 as shown in Figure 10, a force that tries to restore the deformation is likely to be generated in slit 72, and a strong frictional force is likely to be generated between the sandwiched object and the edge of slit 72.

[0040] As shown in FIG. 10 , a guide portion 72A having a shape that narrows toward the rear of the slit 72 is provided at the end of the slit 72 opposite the wall portion 61B. The rear side of the slit 72 here refers to the wall portion 61B side. The width direction of the guide portion 72A is perpendicular to the extension direction of the slit 72 and perpendicular to the thickness direction of the flap 64A. In other words, when the width direction of the guide portion 72A is defined as above, the guide portion 72A has a tapered shape that gradually narrows toward the rear. At the rear side of the guide portion 72A, the inner edges of the slit 72 face each other and are in close contact with each other. This configuration makes it easy to insert a thin object into the slit 72. By pushing the inserted object further toward the rear, the object can be easily inserted into the rear of the slit 72.

[0041] 4. Installation method The following description relates to an installation method for installing the mounting plate 1 and the remote controller 100 on the target wall W. The installation method described below mainly includes a preparation step, a fixing step, and an installation step. The preparation step is a step of preparing the mounting plate 1 and the storage box 60. The fixing step is a step of fixing the mounting plate portion 10 of the mounting plate 1 to the wall W. The installation step is a step of attaching the remote controller 100 to the mounting portion 30.

[0042] In the preparation step, the above-described mounting plate 1 is prepared. That is, in the preparation step, a mounting plate 1 is prepared that includes a fixing plate portion 10, an insertion portion 50 configured as a hole or notch for passing an electric wire 180 led out from the wall W side, and a mounting portion 30 provided integrally with the fixing plate portion 10. The mounting plate 1 only needs to have the above-described configuration illustrated in FIGS. 1 to 4 when it is attached to the wall W. Therefore, the specific method for forming the mounting plate 1 is not particularly limited, and the above-described configuration can be formed, for example, by known metal processing of a metal plate. The mounting plate 1 may also be made of a resin material, in which case the mounting plate 1 can be formed by known resin molding such as injection molding.

[0043] Furthermore, in the preparation step, the above-described storage box 60 (a storage box for storing the remote controller 100) is prepared. That is, in the preparation step, specifically, as described above, the storage box 60 is configured so that the peripheral wall portion 61 is formed by the wall portions 61A, 61B, 61C, and 61D, the bottom wall portion 62 is connected to the lower end of the peripheral wall portion 61, the upper end is open, and the box-shaped portion with the open upper end is closed by the upper wall portion 63 configured as a lid. In the step of preparing this storage box 60, the above-described slit 72 for hanging the electric wire 180 is provided in the edge portion of the storage box 60. Specifically, in the preparation step, the flap 64A is provided so as to be displaceably connected to the peripheral wall portion 61, and the slit 72 is provided in the flap 64A in the longitudinal middle portion of the outer edge extending in the longitudinal direction of the flap 64A. The width direction of the insertion portion 50 (hole) is the longitudinal direction of the insertion portion 50 (hole), and in the example shown in FIGS. 1 and 2, etc., the lateral direction (left-right direction) of the insertion portion 50 is the width direction of the insertion portion 50. The up-down direction of the mounting plate 1 is the direction that becomes the vertical direction when the mounting plate 1 is attached to the wall W, and the lateral direction (left-right direction) of the mounting plate 1 is the direction that is perpendicular to the up-down direction of the mounting plate 1 and perpendicular to the plate surface 10A. The longitudinal length of the plate-like portion (flap 64B in this embodiment) in which the slit 72 is provided is greater than the vertical length from the upper end to the lower end of the insertion portion 50 (hole) (maximum vertical length) and is greater than the horizontal length from one left-right end to the other left-right end of the insertion portion 50 (hole).

[0044] In the preparation step, for example, slits 72 are provided in the longitudinally intermediate portion of the outer edge portion extending in the longitudinal direction of each of the flaps 64A and 64B. In the example of Fig. 6, both the flaps 64A and 64B are configured as plate-like portions provided with the slits 72. Two slits 72 are provided in the flap 64A, and one slit 72 is provided in the flap 64B.

[0045] It is sufficient that the storage box 60 has the above-described configuration at least when the fixing step described below is performed, and it is desirable that the storage box 60 has the above-described configuration when it stores the remote controller 100 and is shipped. The specific method for forming the storage box 60 prepared in the preparation step is not particularly limited, but for example, the above-described configuration can be formed by known processing of paper such as cardboard. The preparation of the mounting plate 1 and the preparation of the storage box 60 may be performed in either order, or may be performed at the same time.

[0046] When the remote controller 100 is attached to a wall W (a wall on which the remote controller 100 is to be installed), as shown in FIG. 7, the electric wire 180 is drawn out in advance from a through-hole Wa provided in the wall W to which the remote controller 100 is to be attached. The drawn out electric wire 180 may be configured in such a manner that a plurality of individual electric wires (for example, individual electric wires each having a conductor individually coated thereon) are bundled together by a coating portion 182, as shown in FIGS. 7 and 8, or may be configured in such a manner that a plurality of individual electric wires each having a surface formed by a coating member are bundled together in an exposed state. The drawn out electric wire 180 may be one or two or more. A specific configuration of the drawn out electric wire 180 may include, for example, an electric wire portion formed by bundling a plurality of individual electric wires, the individual electric wires being branched into a plurality of wires at the tip end of the electric wire portion. In the representative example shown in FIGS. 7 and 8, the tip end of the electric wire portion formed by bundling a plurality of electric wires is branched into a plurality of wires as shown in FIG. 10.

[0047] When installing the remote controller 100 with the wires 180 pulled out from the through-hole Wa into the space Wc as shown in Fig. 7, the fixing step is performed after the above-described preparation step. The work of pulling out the wires 180 from the through-hole Wa into the space Wc may be performed before the preparation step, after the preparation step, or after the start of the preparation step but before its completion. The fixing step includes a first step and a second step.

[0048] The first step is a step of passing the electric wire 180 led out from the wall W side through the insertion portion 50 of the mounting plate 1 prepared in the preparation step, as shown in Figures 8 and 9. In the first step, the electric wire 180 is arranged so as to be inserted into the through-hole portion Wa and to straddle the back side (the side opposite to the side on which the mounting plate 1 is arranged) and the front side (the side on which the mounting plate 1 is arranged) of the through-hole portion Wa, and then in the first step, the portion of the electric wire 180 arranged on the front side of the through-hole portion Wa (the portion arranged in the space Wc) is inserted into the insertion portion 50, as shown in Figures 8 and 9.

[0049] The second step is a step of hooking the electric wire 180 into the slit 72 of the storage box 60 prepared in the preparation step. In this embodiment, the storage box 60 is a box that stores the remote controller 100 when the remote controller 100 is shipped or sold, and the second step includes a removal step of removing contents such as the remote controller 100 (contents stored in the storage box 60) from the storage box 60 in which the remote controller 100 is stored. The second step also includes a hooking step of inserting the electric wire 180 into the slit 72 provided in the storage box 60 and hooking it. Note that, in the second step, it is preferable that the hooking step is performed after the removal step, but the removal step may also be performed after the hooking step. In the representative example shown in FIG. 10 , the second step is performed after the first step, and a part of the electric wire 180 after being passed through the insertion portion 50 is hooked into the slit 72. 10 , two electric wires 180A and 180B branching off from the tip end of the electric wire 180 are hooked into two slits 72, respectively. When the electric wire 180A is inserted into one of the slits 72, the electric wire 180A is sandwiched between the slits 72 and held by friction. That is, when the electric wire 180A is sandwiched between one inner edge portion of one slit 72 and the other inner edge portion of the other slit 72, a friction force is generated between the inner edge portion of the slit 72 and the surface portion of the electric wire 180A, and the electric wire 180A is held in a sandwiched state in the slit 72. Similarly, when the electric wire 180B is inserted into the other slit 72, the electric wire 180B is sandwiched between the slit 72 and held by friction. That is, when one inner edge portion of the other slit 72 and the other inner edge portion of the other slit 72 sandwich the electric wire 180B, a frictional force is generated between the inner edge portion of the slit 72 and the surface portion of the electric wire 180B, and the electric wire 180B is held in a sandwiched state in the slit 72.

[0050] When the first and second steps are performed in this manner, the electric wire 180 is held in the storage box 60, so that even if the worker temporarily lets go of the electric wire 180, the electric wire 180 is less likely to fall behind the wall W.

[0051] After the fixing step (temporarily fastening step) is performed in this manner, a "connecting step of connecting the electric wire 180 to the gas appliance remote controller 100" and a "wall fixing step of fixing the fixing plate 10 to the wall W" are performed. That is, the electric wire 180 led out from the wall W side is passed through the insertion portion 50, and the electric wire 180 is hooked in the slit 72, and then a step of fixing the fixing plate 10 to the wall W or a step of connecting the electric wire 180 to the remote controller 100 is performed. When performing the connecting step and the wall fixing step in this manner, one of the steps may be performed first and the other step may be performed later, or both steps may be performed in parallel.

[0052] In the example of FIG. 11 , the wall fixing step is performed before the connecting step, and the fixing plate 10 is fixed to the wall W with fixing members such as screws. Note that FIG. 11 does not show the housing box 60 in which the electric wires 180 are hooked at their tip ends. The fixing method for fixing the fixing plate 10 to the wall W is not limited. For example, a screw may be inserted into a hole formed in the fixing plate 10 so as to penetrate the plate in the thickness direction, and the screw may be inserted into the wall to fix the mounting plate 1 to the wall W. Note that the method for fixing the fixing plate 10 to the wall W is not limited to the method using a screw, and any method may be used as long as it can fix the fixing plate 10 to the wall W. For example, the fixing may be performed by interposing an adhesive or the like between the back surface of the fixing plate 10 and the surface of the wall W.

[0053] When the wall fixing step is performed first as shown in FIG. 11 , the connecting step is performed after the wall fixing step, and the electric wire 180 is electrically connected to the remote controller 100. In this embodiment, as shown in FIG. 2 , a plurality of terminals 110 are provided on the back side of the remote controller 100, and in the connecting step, each of the individual electric wires (not shown) provided on the electric wire 180 is electrically connected to each of the plurality of terminals 110. Various known methods can be used to connect the electric wires to the terminals 110. In the example of FIG. 2 , the connection method employs a configuration in which the terminals of the individual electric wires 180A, 180B are sandwiched between a metal plate constituting a part of the terminal 110 and the screw head of a screw member, but is not limited to this example. For example, a configuration in which a connector is provided at the end of the electric wire 180 and a connector is also provided on the remote controller 100, and the connectors are connected to each other, or other connection configurations are also possible.

[0054] After the wall fixing step and the connecting step, an attachment step is performed. The attachment step is a step of attaching the remote controller 100 to the attachment portion 30 of the attachment plate 1. In the attachment step, as shown in FIG. 11 , the protrusions 32 arranged to protrude forward from the attachment plate portion 10 of the attachment plate 1 fixed to the wall W are inserted into the holes 108 of the remote controller 100, and the upper end portions of the holes 108 are placed on the protrusions 32. Then, the protrusions 33 of the protrusions 32 are attached so as to hook from the front onto the ends of the holes 108 (the ends of the holes 108 that are positioned in front of the protrusions 33 when the protrusions 32 are inserted into the holes 108). FIG. 12 illustrates an example of the configuration after attachment. Note that FIGS. 11 and 12 show an example of an attachment structure and an attachment method, but the present invention is not limited to these structures and methods. For example, a structure and method may be adopted in which recesses are formed on the attachment plate side and protrusions are formed on the remote controller side, and the protrusions are inserted into the recesses to be hooked. Alternatively, a structure or method may be adopted in which a first portion for inserting a connecting member such as a screw is provided on the mounting plate side, a second portion for inserting a connecting member such as a screw is provided on the remote controller side, and a common connecting member is inserted into and fixed to the first portion and the second portion. Alternatively, other structures or methods may be adopted.

[0055] 5.Example of effects The above-described method for installing a gas appliance remote controller includes the steps of passing the electric wire 180, which is led out from the wall W side, through the insertion portion 50 of the mounting plate 1 prepared in the preparation step, and hooking the electric wire into the slit 72 of the storage box 60 prepared in the preparation step. When these steps are performed, as shown in FIG. 10 , the drawn-out electric wire 180 is passed through the insertion portion 50, and the mounting plate 1 is interposed between the storage box 60 with the electric wire 180 hooked in the slit 72 and the wall W. Therefore, even if a worker loses his / her grip on the electric wire 180 during installation and the electric wire 180 is about to be pulled into the wall W, the storage box 60 with the electric wire 180 hooked is likely to be caught near the insertion portion 50 of the mounting plate 1. Therefore, the electric wire 180 is unlikely to fall into the wall W, making it easier for the worker to install the gas appliance remote controller 100.

[0056] The above-mentioned method of installing the remote controller for gas appliances involves hooking the electric wire 180 so as to connect the electric wire 180 to the box body 60A, which is formed by integrally connecting the peripheral wall portion 61, the bottom wall portion 62, and the upper wall portion 63 (lid portion), so that after the hooking process, it is unlikely that the hooked portion of the electric wire 180 will come out of the insertion portion 50.

[0057] The above-described method of installing a remote controller for gas appliances makes it easy to form slits 72 in the storage box 60 during the preparation process, and during the fixing process, the electric wire 180 can be hooked directly into the slits 72 present on the edge, making it easy to hook the electric wire 180 into the slits 72.

[0058] In the above-described installation method for a remote controller for a gas appliance, the slits 72 are provided in the flap 64A, which is unlikely to affect the aesthetic appearance, and therefore the provision of the slits 72 is unlikely to detract from the aesthetic appearance of the entire storage box 60. Furthermore, because the slits 72 are provided in the flap 64A, the presence of the slits 72 is unlikely to significantly reduce the strength of the outer wall of the box.

[0059] 10, the above-described installation method for the gas appliance remote controller makes it easier to hold the electric wires more securely because the electric wires can be divided and hooked into each slit 72. For example, even if the holding of the electric wire in one slit 72 is released, the holding is likely to be maintained in the other slits 72, making it less likely that all the electric wires will be released.

[0060] <Other embodiments> The present disclosure is not limited to the embodiments described above and in the drawings. For example, any combination of features of the above-described or following embodiments is possible within a range that does not contradict. Furthermore, any feature of the above-described or following embodiments may be omitted unless explicitly stated as essential. Furthermore, the above-described embodiment may be modified as follows.

[0061] In the embodiment described above, the hole 108 of the remote controller 100 is the portion where the remote controller is attached so as to be hooked onto the mounting portion 30, but the remote controller may be attached in a configuration different from that shown in Fig. 2, etc., and the mounting portion and the remote controller may be fixed with a connecting member such as a screw. For example, a plate piece configured to extend forward from the peripheral edge of the fixing plate may be fixed to the side wall or bottom wall of the case 102 with a connecting member such as a screw.

[0062] In the embodiment described above, the wall fixing step is performed before the connecting step, but the connecting step may be performed before the wall fixing step. That is, after the second and third steps, a step of connecting the electric wire 180 to the remote controller 100 may be performed in a state in which the electric wire 180 led out from the wall W side is passed through the insertion portion 50 and the electric wire 180 is hooked in the slit 72, and then the fixing plate 10 may be fixed to the wall W, and then the installation step may be performed.

[0063] In the embodiment described above, a plurality of slits 72 are provided in one flap 64A of the storage box 60, but as in the other flap 64B in Fig. 6, only one slit 72 may be provided and the electric wire 180 may be hooked in only this one slit 72. Alternatively, three or more slits may be provided and the electric wire may be hooked in each of them.

[0064] In the above-described embodiment, the slits are provided in the flap, but they may be provided in a location other than the flap. For example, the slits may be provided in the edge of the upper wall portion 63 or the edge of the insertion portion 65.

[0065] It should be noted that the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is not limited to the embodiments disclosed herein, but is intended to include all modifications within the scope indicated by the claims or the scope equivalent to the claims.
