Modes for Carrying Out the Invention

[0010] Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a wall-mounted heater which is a type of home electric appliance, and the whole is composed of a box-shaped case 2. On the front side of the case 2, heaters 3 and 4 as driving parts for performing radiant heating, a reflector 5 covering the heaters 3 and 4, and a blower mechanism 6 for blowing air toward the reflector 5 are installed.

[0011] Further, filters 7 and 8 are attached to the left and right ends of the case 2, respectively. The filters 7 and 8 are provided generally along the vertical axis in order to suppress the deposition of dust and dirt.

[0012] The case 2 includes a planar back portion 9 fixed to the wall, a planar ceiling portion 10 extending from the upper end of the back portion 9 into the room, and a curved front portion 11 extending from the tip of the ceiling portion 10 to the lower end of the back portion 9. The ceiling portion 10 extends with a gentle downward gradient from the wall into the room. The front portion 11 is formed by a gentle curved surface, and an opening 12 is formed across the width direction at the lower part of the front portion 11, and the heaters 3 and 4 face the room from the opening 12.

[0013] A wire netting 13 for protecting the heaters 3 and 4 is covered on the opening 12. Further, as the heaters 3 and 4, bar heaters extending horizontally are used, and they are arranged offset up and down.

[0014] The heater 3 arranged below is located closer to the wall surface W than the heater 4 arranged above. Note that, as the heaters 3 and 4, horizontally long planar heaters can also be used, and the number of the heaters 3 and 4 is arbitrary.

[0015] The reflector 5 is a metal plate that presents a substantially W-shaped profile in side view, and reflects the heat rays emitted by the heaters 3 and 4 toward the interior of the room. It has a lower reflector main body portion 14 (reflector main body portion 14) that covers the heater 3 and presents a substantially U-shaped profile in side view, a lower extension portion 15 (extension portion 15) that extends from the lower end of the lower reflector main body portion 14 toward the interior of the room, an upper reflector main body portion 16 that covers the heater 4 and presents a substantially U-shaped profile in side view, an upper extension portion 17 that extends from the upper end of the upper reflector main body portion 16 toward the interior of the room, and a reflector connection portion 18 that connects the lower reflector main body portion 14 and the upper reflector main body portion 16.

[0016] The lower reflector main body portion 14 covers the upper and rear sides (the side portion on the wall side with respect to the heater 3) of the heater 3. Among the lower reflector main body portion 14, the portion covering the upper side of the heater 3 has a gentle upward gradient from the wall side toward the interior side of the room.

[0017] Also, the lower extension portion 15 extends with a downward gradient from the boundary portion 19 with the lower reflector main body portion 14 toward the interior of the room. The tip of the lower extension portion 15 is located below the heater 3, and the boundary portion 19 between the lower reflector main body portion 14 and the lower extension portion 15 is spaced apart from the back surface portion 9 of the case 2.

[0018] Also, the upper reflector main body portion 16 covers the upper and rear sides (the side portion on the wall side with respect to the heater 4) of the heater 4. Among the upper reflector main body portion 16, the portion covering the upper side of the heater 4 has a gentle upward gradient from the wall side toward the interior side of the room.

[0019] Also, the upper extension portion 17 extends with an upward gradient from the boundary portion 20 with the upper reflector main body portion 16 toward the interior of the room. The tip of the upper extension portion 17 extends to the vicinity of the edge of the opening 12, and there is a slight gap between the tip of the upper extension portion 17 and the edge of the opening 12.

[0020] Also, the reflector connection portion 18 has ventilation holes that are formed across the width direction and through which air from the blower mechanism 6 passes, thereby suppressing the accumulation of heat in the vicinity of the reflector 5.

[0021] The blower mechanism 6 includes a fan motor 21 positioned at the center in the width direction of the case 2, and left and right sirocco fans 22 (only the right sirocco fan 22 is shown) arranged on the left and right of the fan motor 21 and driven by the fan motor 21. The air generated in the blower mechanism 6 mainly reaches the room through the opening of the reflector connection part 18, and a part of the air generated in the blower mechanism 6 reaches the room through the space between the lower reflector main body part 14 and the back part 9 of the case 2.

[0022] 23 is a room temperature detection means, which is provided near the filter 7 at the end in the case 2, and detects the room temperature by detecting the temperature of the air flowing in through the filter 7.

[0023] 24 is a control unit composed of a control board, which is provided in a storage part 26 formed by the front part 11 of the case 2 and a partition wall 25, and is attached to the partition wall 25. It controls the operations of the heaters 3 and 4 and the blower mechanism 6. Specifically, when the control unit 24 determines that an operation start operation of a remote control (not shown) has been performed, it drives the heaters 3 and 4 and drives the fan motor 21 at a predetermined rotational speed. When the control unit 24 determines that an operation stop operation has been performed with a remote control (not shown), it stops the driving of the heaters 3 and 4, and after a predetermined time has elapsed, stops the operation of the fan motor 21. After the heaters 3 and 4 are stopped, the sirocco fan 22 is driven for a predetermined time to cool the inside of the case 2 where the temperature has risen, and prevent damage due to the thermal influence of the constituent members of the case 2.

[0024] Next, the detailed structure of the back part 9 that constitutes the back side of the case 2 of the present embodiment will be described with reference to FIGS. 3 to 6.

[0025] On the back surface 9, a plurality of vertical ribs 27 extending in the vertical direction and a plurality of horizontal ribs 28 extending in the horizontal direction are formed. By forming a plurality of vertical ribs 27 and horizontal ribs 28 on the back surface 9, the case 2 is reinforced. The vertical ribs 27 and the horizontal ribs 28 are formed such that the height extending in the rear direction is below the outer edge of the back surface 9. When the case 2 is installed on the indoor wall surface W, the case 2 does not lift up due to the vertical ribs 27 and the horizontal ribs 28 stretching.

[0026] 29 is a terminal block cover installed on the right side of the back surface 9 and having a terminal block (not shown) inside, and 30 is a power cord connected to the terminal block. The power transmitted by the power cord 30 is sent to the control unit 24 via the terminal block. The control unit 24 controls the driving states of the heaters 3, 4 and the fan motor 21 with the transmitted power.

[0027] 31 is a support plate as wall fixing means installed on the back surface 9, and is fixed by being hooked on a mounting plate 32 as wall fixing means installed on the indoor wall surface W and located on the back of the support plate 31, so that the case 2 can be installed on the indoor wall surface W.

[0028] 33 is a notch formed in the middle of the vertical rib 27. A total of four notches 33 are formed in two places each in the middle of two vertical ribs 27 located at an equal distance from the center of the back surface 9. The vertical width of the notch 33, which is the distance between the upper end 33a and the lower end 33b formed by cutting the vertical rib 27 forward by a predetermined depth, is formed to be larger than the width of the power cord 30. Thereby, the power cord 30 can pass between the upper end 33a and the lower end 33b of the notch 33, and the power cord 30 can be supported at the lower end 33b of the notch 33.

[0029] 34 is a flexible wide rib formed within the width of each of the four notches 33. The wide rib 34 protrudes rearward from the back surface portion 9 and is formed in a planar shape with a length in the left-right direction longer than the upper end 33a and the lower end 33b of the notch 33. The vertical width formed by the upper end 33a and the lower end 33b of the notch 33 and the wide rib 34 is larger than the width of the power cord 30, and the power cord 30 can pass between the upper end 33a and the lower end 33b of the notch 33 and the wide rib 34. When the power cord 30 passes between the upper end 33a of the notch 33 and the wide rib 34, the power cord 30 is supported by the wide rib 34.

[0030] 35 is a clip band having a plurality of positions on the back surface portion 9 and having one end screwed. The clip band 35 sandwiches the power cord 30 extending from the terminal block cover 29 to prevent the power cord 30 from hanging down from the lower end of the case 2. Since the clip band 35 is housed in a groove portion formed in the back surface portion 9, it does not protrude rearward from the outer edge of the back surface portion 9.

[0031] 36 is a hook projection formed at a plurality of positions on the back surface portion 9 and formed to protrude rearward. When the power cord 30 is routed around the back surface portion 9, the hook projection 36 supports the power cord 30 at each part, facilitating the routing operation of the power cord 30 by the user and preventing the power cord 30 from hanging down from the lower end of the case 2.

[0032] 37 is a discharge recess formed at the outer edge of the back surface portion 9. The discharge recess 37 is formed at four positions on the upper and lower outer edges of the back surface portion 9. When the case 2 is wall-mounted on the wall surface W, the power cord 30 is drawn out from the discharge recess 37 at a position where the position of an outlet (not shown) is close to the case 2. The power cord 30 drawn out from the case 2 can be connected to the outlet at the shortest distance. In the present embodiment, the power cord 30 is drawn out from the discharge recess 37 located at the lower right of the back surface portion 9.

[0033] Next, the routing of the power cord 30 on the back surface portion 9 of the case 2 will be described.

[0034] Before the user wall-mounts and fixes Case 2 to the indoor wall surface W, the user performs an operation of routing the power cord 30 for the portion excluding the part between Case 2 and an outlet (not shown) at the back surface 9. The user sandwiches and fixes the power cord 30 extending from the terminal block cover 29 between clip bands 35 located around the terminal block cover 29, and routes the power cord 30 so as to surround the periphery of the terminal block cover 29. By routing the power cords 30 so that they are not close to each other, it is possible to prevent heat damage to the power cord 30 due to heat generation when the heaters 3 and 4 are driven.

[0035] Thereafter, the user pushes the power cord 30 so that it passes between the upper end 33a of the upper left and right cutouts 33 and the wide rib 34, between the lower end 33b of the upper left and right cutouts 33 and the wide rib 34, and between the upper end 33a of the lower left and right cutouts 33 and the wide rib 34, and routes the power cord 30. As a result, the power cord 30 is supported by the cutouts 33. In particular, the power cord 30 passing between the upper end 33a of the cutout 33 and the wide rib 34 is supported by the wide rib 34 that is longer in the left-right direction than the lower end 33b of the cutout 33. Thus, the load on the power cord 30 is applied to the wide rib 34 in a planar manner and does not concentrate at a single point. The risk that the load on the power cord 30 concentrates at a single point and generates heat can be reduced. Further, since the wide rib 34 is flexible, the wide rib 34 bends when the user pushes the power cord 30 between the upper end 33a of the cutout 33 and the wide rib 34. It is possible for the user to easily push and fix the power cord 30 between the upper end 33a of the cutout 33 and the wide rib 34. The workability of routing the power cord 30 by the user is improved.

[0036] When passing the power cord 30 through the notch 33, the user makes a U-turn of the power cord 30 above the hook protrusion 36 which is located in the left-right direction of the notch 33 and is in a substantially H shape tilted 90° in a rear view. Also, when the user routes the power cord 30 to the left and right notches 33, the user routes it so as to pass over the cylindrical hook protrusion 36 which is at a substantially central position of the back surface portion 9. By hooking and supporting the power cord 30 on each hook protrusion 36, it is possible to prevent in advance a state where the power cord 30 sags and becomes difficult for the user to route it.

[0037] After passing the power cord 30 through each notch 33, the user sandwiches and supports the power cord 30 with the clip band 35 installed at the lower right of the back surface portion 9, and takes it out of the case 2 from the discharge recess 37 located at the lower right of the back surface portion 9. Since the power cord 30 is routed on the back surface portion 9 for the portion except the part from the discharge recess 37 to the outlet, the power cord 30 with the excess length does not sag outside the case 2 and does not damage the appearance.

[0038] When the routing of the power cord 30 on the back surface portion 9 is completed, the user installs the support plate 31 of the case 2 on the mounting plate 32 fixed to the indoor wall surface W. When the case 2 is installed on the indoor wall surface W, the outer edge of the back surface portion 9 abuts against the wall surface W. The vertical rib 27, the horizontal rib 28, the clip band 35, and the hook protrusion 36 are located in front of the outer edge of the back surface portion 9. On the back surface portion 9, since there is no protrusion protruding from the back surface portion 9 to support the power cord 30, if there is a space with a margin added to the vertical width and the horizontal width of the case 2, the case 2 can be installed on the indoor wall surface W. When installing the case 2 on the indoor wall surface W, since the user does not need to consider the protrusion protruding from the back surface portion 9 of the case 2, the degree of freedom of the installation location of the product does not decrease and the product quality is improved.

[0039] In addition, in this embodiment, the description has been made with the content that four notches 33 are formed in the back surface portion 9, but it is not limited to this. As long as it is a location where the vertical rib 27 extending in the vertical direction is formed, the notch 33 may be formed at any position, and the number and position of the notches 33 in the back surface portion 9 are not limited.

[0040] Also, in this embodiment, the routing of the power cord 30 when taking out the power cord from the discharge recess 37 located at the lower right position of the back surface portion 9 has been described, but the present invention is not limited to this. Even when taking out the power cord 30 from the discharge recess 37 formed at other locations, by routing the cutout portion 33 so that the power cord 30 passes through it, the user can easily route the power cord 30 on the back surface portion 9.

[0041] Next, the effects of the present invention will be described.

[0042] In the middle of the vertical rib 27 formed on the back surface portion 9 of the case 2, a cutout portion 33 is formed which has an up-and-down width at least larger than the width of the power cord 30 and can support the power cord 30. When supporting the power cord 30 on the back surface portion 9 of the case 2, the power cord 30 can be supported without providing a power cord holding body or the like that protrudes rearward from the back surface portion 9 and is separate from the back surface portion 9. When the user installs the case 2 indoors, rearward from the outer edge of the back face 9 it can be installed without considering the protruding protrusions, so the degree of freedom of the installation location of the product does not decrease and the product quality is improved.

[0043] Also, in the cutout portion 33, a planar wide rib 34 is formed which is at least longer in the left-right direction than the lower end 33b of the cutout portion 33 and can support the power cord 30. When the power cord 30 passes through the cutout portion 33, the power cord 30 is supported by the wide rib 34. Since the wide rib 34 is longer in the left-right direction than the lower end 33b of the cutout portion 33, the load on the power cord 30 is applied to the wide rib 34 in a planar manner and does not concentrate at a single point. The risk of the load on the power cord 30 concentrating at a single point and generating heat can be reduced.

[0044] Also, the case 2 installed on the back face 9It is installed on the indoor wall surface W by a support plate 31 and a mounting plate 32 as wall fixing means, and the drive unit is composed of heaters 3 and 4 that are heated to a high temperature state when power is transmitted. The routing structure of the power cord 30 of the present invention is applied to a wall-mounted heater 1 that installs a case 2 on the indoor wall surface W and heats the room by the heaters 3 and 4. When the power cord 30 hangs down from the back surface portion 9 with the case 2 installed on the indoor wall surface W, the appearance is impaired. By supporting the power cord 30 with the notch portion 33 formed in the back surface portion 9, it is possible to prevent the power cord 30 from hanging down from the back surface portion 9, and it is possible to prevent a decrease in appearance.

[0045] In addition, in the present embodiment, the present invention has been described in the context of being applied to a wall-mounted heater 1 which is a type of home appliance, but the scope of application of the present invention is not limited to the wall-mounted heater 1. For example, the present invention may be applied to the back surface portions of floor-standing electric heaters, dehumidifiers, humidifiers, etc., and the type of home appliance is not particularly limited.
