Abstract
Description
[Technical Field]
[0001] The present invention relates to a heat storage device for an iron, steamer, or the like used to smooth out wrinkles in textile products such as clothing. [Background technology]
[0002] Conventionally, a home ironing device has been proposed that is composed of an iron body (1) with a built-in heater, a power supply stand (2) that also serves as a stand and supplies power to the heater when the iron body (1) is placed on it, and a body cover (3) that is detachably attached to the power supply stand (2) and covers the outer periphery of the iron body (1) placed on the power supply stand (2) (see, for example, Patent Document 1).
[0003] The home ironing device described in Patent Document 1 has a power cord (2f) with a plug (2e) attached to one end, which is attached to a power supply stand (2). When the iron body (1) is placed on the power supply stand (2) with the plug (2e) connected to an outlet, power is supplied to the heater, causing it to heat up.
[0004] Usually, after ironing is completed, the iron body (1) is placed on the power supply stand (2), the plug (2e) of the power cord (2f) is removed from the outlet and stored in the power supply stand (2), and then the body cover (3) is attached to the power supply stand (2). [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Publication No. 3100748 Summary of the Invention [Problem to be solved by the invention]
[0006] However, when ironing is finished or interrupted, the user may forget to remove the plug (2e) from the outlet and attach the main body cover (3) to the power supply stand (2) while power is still being supplied to the heater. If the main body cover (3) is attached to the power supply stand (2) while power is still being supplied to the heater, the inside of the main body cover (3) becomes hot, and the temperature of the main body cover (3) itself also rises. In such cases, there is a risk that the user may be burned by touching the main body cover (3) or that the main body cover (3) may be damaged by the heat.
[0007] Therefore, the present invention provides a heat storage device in which power supply to the heater is cut off when a cover is attached to the mounting table while the power plug of the power cord is connected to an outlet. [Means for solving the problem]
[0008] In the heat storage device of the present invention, when the power plug of the power cord is connected to an outlet and the cover is attached to the mounting table, the power supply to the heater can be cut off. [Effects of the Invention]
[0009] According to the heat storage device of the present invention, when the cover is attached to the mounting table with the power plug connected to the outlet, the power supply to the heater can be cut off. [Brief explanation of the drawings]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the heat storage device of the present invention will now be described with reference to the accompanying drawings. Not all of the configurations described below are essential requirements for the present invention.
[0012] Hereinafter, a heat storage device 1 according to a first embodiment of the present invention will be described. As shown in Fig. 1, the heat storage device 1 includes an iron 2 which is a heat storage device main body, a stand 3 on which the iron 2 is placed, and a cover 4 which is detachably attached to the stand 3.
[0013] 1 to 4, the iron 2 has a main body 5 and a grip 6 connected to the top of the main body 5 at two points, the front and the back. In this embodiment, the rear side of the grip 6 is connected to the main body 5, which is a so-called closed handle, but the iron 2 may also be a so-called open handle, in which only the front side of the grip 6 is connected to the main body 5.
[0014] The main body 5 has a metal base 8 at its bottom, in which a heater 7 is embedded as heating means. The base 8 is a die-cast product, and a plate-shaped base plate 9 is tightly fixed to the bottom surface. A vaporization chamber 10 is formed inside the base 8, located near the heater 7, and an ejection hole 11 communicating with this vaporization chamber 10 is formed in the base plate 9 attached to the underside of the base 8. The underside of the base plate 9 forms a horizontal, approximately flat hanging surface 12.
[0015] A tank assembly 13 for storing liquid is detachably provided on the upper front side of the base 8 relative to the main body 5. The tank assembly 13 is formed, for example, from a synthetic resin and has a generally U-shape in plan view. A water filler lid 14 that can be opened and closed is provided on the front of the tank assembly 13, and this lid makes it possible to fill the tank assembly 13 with water, or to discard unnecessary water from the tank assembly 13. Note that, although the tank assembly 13 is described as being a detachable cassette tank in this embodiment, it may also be a fixed tank.
[0016] A water inlet 15 is formed as an opening on the front surface of the tank assembly 13, and an openable water inlet lid 14 is provided on this water inlet 15, which rotates around a hinge 16. The water inlet lid 14 tightly seals the water inlet 15, thereby preventing water from leaking out of the water inlet 15.
[0017] The grip part 6 has a cavity 18 between it and the abdomen 17 of the main body 5, and is formed so that a hand can be inserted into this cavity 18 to grip the grip part 6. In other words, the abdomen 17 here refers to the flat central upper surface portion of the main body 5 facing the grip part 6, excluding both sides of the tank assembly 13.
[0018] An operation unit including a steam / dry switch lever 19, a shot button 20 for increasing the amount of steam, a mist button 21 for spraying mist, and a temperature set / off button 22 is provided on the top of the iron 2. A temperature indicator lamp 23 consisting of an array of LEDs is also provided on the top of the iron 2 as a display unit, and the temperature set by the temperature set / off button 22, the temperature of the base 8 detected by a temperature detection means (not shown), etc. is displayed on the temperature indicator lamp 23.
[0019] A partition member 26 is provided inside the tank assembly 13, dividing the interior into an upper and lower storage chamber 24 that stores water from the water inlet 15 and a mechanism movable chamber 25 that houses the operating parts and their movable mechanism excluding the temperature setting / off button 22. The storage chamber 24, which serves as a liquid storage space, is formed by a tank case 27 that is substantially U-shaped in a plan view and a flat tank base 28 that closes the bottom opening of the tank case 27, and the partition member 26 is formed integrally with the tank case 27 on the front side of the tank assembly 13.
[0020] A liquid guide passage 29 communicating with vaporizing chamber 10 is provided below tank assembly 13. A heat shield 30 that insulates against heat from base 8 is interposed between liquid guide passage 29 and base 8. A lid 31 that covers the upper opening of vaporizing chamber 10 is provided below heat shield 30. An on-off valve 32 that opens and closes liquid guide passage 29 protrudes downward from an opening 33 provided in heat shield 30 toward a concave bimetal housing portion 34 formed on the upper surface of base 8. A reversible bimetal 35 that corresponds to a thermosensitive element is housed in bimetal housing portion 34. When vaporizing chamber 10 near bimetal housing portion 34 reaches a predetermined temperature, bimetal 35 reverses inside bimetal housing portion 34 and pushes up on-off valve 32 against the bias of a spring (not shown), thereby opening liquid guide passage 29.
[0021] The temperature control device 36 provided inside the grip part 6 is configured by mounting on the upper surface of a circuit board 40 with pattern wiring not only a switch part 38 of a setting button 37 that constitutes the temperature set / off button 22, but also a temperature display lamp 23, and a power storage device 39 such as a capacitor that stores and holds the current set temperature and enables the setting of the setting button 37. The light from the temperature display lamp 23 passes through a sheet-like temperature display plate 41 attached to the surface of the grip part 6, and displays the current set temperature.
[0022] Temperature control device 36 receives a temperature detection signal from temperature detection means (not shown) that detects the temperature of vaporization chamber 10, i.e., base 8, a current detection signal from current detection means (not shown) that detects the supply of power at power receiving terminal 43 (described later), and a control signal from temperature set / off button 22, and controls heater 7, which heats base 8 when power is supplied, and also controls the operation of temperature indicator lamp 23. In iron 2, these controls are performed when power is supplied and in a current-on state, and are not controlled by temperature control device 36 when iron 2 is removed from mounting base 3. Note that when iron 2 is placed on mounting base 3 and in a power-supply state, power is also supplied to power storage device 39, which stores the supplied power and supplies operating voltage to various components, enabling temperature control device 36 to operate.
[0023] When the temperature setting / off button 22 is pressed to set the temperature according to the fabric to be ironed, the operation signal is sent by the temperature control device 36, and the temperature control device 36 controls the power on / off of the heater 7 based on the temperature detection signal from the temperature detection means so that the temperature of the base 8 becomes the set temperature, thereby heating the base 8 including the evaporation chamber 10.
[0024] Thereafter, when the temperature control device 36 detects that the temperature of the base 8 has reached the set temperature through a temperature detection signal from the temperature detection means, it controls the temperature indicator lamp 23 to light up. Therefore, by checking the temperature indicator lamp 23, the user can at a glance understand whether the iron 2 is ready for use.
[0025] A concave connection receiving portion 42 is formed at the rear end portion of the main body 5. The connection receiving portion 42 is provided with a pair of power receiving terminals 43 that can be electrically connected to power supply terminals 57 of a power supply connection portion 48, which will be described later.
[0026] As shown in FIG. 5, the stand 3 includes main body placement sections 46, 47 for placing the iron 2 with the front of the iron 2 facing diagonally upward relative to the surface G, a power supply connection section 48 provided at the rear and protruding forward, a power cord 49, and a microswitch 50 as a detector.
[0027] The main body placing sections 46, 47 are provided on the upper surface 51 of the stand 3, and the main body placing section 46 arranged on the front side is formed higher than the main body placing section 47 arranged on the rear side. When the iron 2 is placed on the stand 3, the power supply connector 48 is inserted into the connection receptacle 42, and the iron 2 is supported at three points, the main body placing sections 46, 47 and the power supply connector 48, so that the ironing surface 12 does not come into contact with the upper surface 51.
[0028] Concave locking receiving portions 52, 53 for locking the cover 4 are formed on the left and right side surfaces of the mounting base 3. Furthermore, a protrusion hole 54 is formed on the left side surface of the mounting base 3, behind the locking receiving portion 52, from which an operation protrusion 65 of a switch operating portion 61 constituting a switch unit 60 (described later) protrudes. Furthermore, a cord outlet portion 55 for pulling out the power cord 49 is formed on the right side surface of the mounting base 3, behind the locking receiving portion 53.
[0029] As shown in Fig. 4, the power supply connection part 48 has a pair of power supply holes 56 formed therein, through which the power receiving terminals 43 of the iron 2 are inserted. When the power receiving terminals 43 are inserted into the power supply holes 56, the power receiving terminals 43 are electrically connected to power supply terminals 57 provided inside the power supply connection part 48. A power plug 58 is provided at one end of the power cord 49, and when the power plug 58 is inserted into a household outlet (not shown), the power receiving terminals 43 and the power supply terminals 57 are connected, thereby supplying power to the iron 2.
[0030] 3, 4, and 6, a cord reel 59 for winding up the power cord 49 is provided inside the mounting table 3, allowing the power cord 49 to be stored inside the mounting table 3. When the power cord 49 is completely stored, only the power plug 58 is exposed to the outside of the mounting table 3 from the cord outlet portion 55, but the power plug 58 is positioned so that it does not come into contact with the cover 4 when the cover 4 is attached to the mounting table 3. To insert the power plug 58 into a household outlet, one simply grasps the power plug 58 and pulls out the power cord 49.
[0031] A switch unit 60 is provided inside the mounting table 3. The switch unit 60 includes a microswitch 50, a switch operation part 61, and a coil spring 62 as a biasing means for biasing the switch operation part 61.
[0032] The microswitch 50 has a configuration in which a contact (not shown) is opened or closed by reciprocating an actuator portion 63. The microswitch 50 is provided midway along a wire 64 that electrically connects the power cord 49 and the power supply terminal 57, and switches between energizing and cutting off the power supply terminal 57.
[0033] The switch operating unit 61 has an operating protrusion 65 that protrudes from the protrusion hole 54 to the outside of the mounting base 3, a contact portion 67 that contacts an inner wall surface portion 66 of the mounting base 3, a pressing portion 68 that engages with the actuator portion 63 of the microswitch 50, an insertion portion 69 into which the coil spring 62 is inserted, and a biased portion 70 that receives the biasing force from the coil spring 62. The coil spring 62 is housed in a spring housing portion 71 provided inside the mounting base 3 with the insertion portion 69 inserted. As shown in FIG. 6 , the microswitch 50 is disposed to the left of the power supply connection portion 48, and the cord outlet portion 55 is disposed to the right of the power supply connection portion 48. In other words, the microswitch 50 is disposed on one side of the power supply connection portion 48, and the cord outlet portion 55 is disposed on the other side.
[0034] The operation protrusion 65 is constantly biased by the biasing force of the coil spring 62 in a direction in which the operation protrusion 65 protrudes from the protrusion hole 54 to the outside of the mounting base 3, and the abutment portion 67 abuts against the inner wall surface portion 66 of the mounting base 3, so that the operation protrusion 65 remains stationary in a state in which it protrudes from the protrusion hole 54 to the outside of the mounting base 3. At this time, the pressing portion 68 does not press the actuator portion 63 of the microswitch 50, and the contacts of the microswitch 50 are closed, allowing current to flow through the wiring 64. When the cover 4 is placed in this state, the cover 4 comes into contact with the operation protrusion 65 and presses it against the biasing force of the coil spring 62. The switch operation portion 61 pressed by the cover 4 moves in a direction in which the operation protrusion 65 enters the inside of the mounting base 3 through the protrusion hole 54, and the pressing portion 68 presses the actuator portion 63. When the actuator part 63 is pressed and moved by the pressing part 68, the contacts of the microswitch 50 change from closed to open, and the wiring 64 enters a state in which it is not energized (a cut-off state). When the cover 4 is removed and the cover 4 moves away from the operation protrusion 65, the pressing force on the operation protrusion 65 is released, and the biasing force of the coil spring 62 causes the operation protrusion 65 to move in a direction in which it protrudes from the projection hole 54 to the outside of the mounting base 3, and the abutment part 67 abuts against the inner wall surface part 66 of the mounting base 3, and the switch operating part 61 comes to a standstill. At this time, the contacts of the microswitch 50 are closed, and the wiring 64 enters a state in which it is energized.
[0035] 1, the cover 4 is made of a heat-resistant synthetic resin and has a cover body 74 that is attached to the stand 3 to cover the iron 2, and a handle 75 that is rotatably provided on the upper part of the cover body 74. In addition, locking portions 76 and 77 that lock onto the locking receiving portions 52 and 53 of the stand 3 are provided on the left and right inner side surfaces of the cover body 74 and protrude inward.
[0036] When the cover 4 is completely attached to the stand 3, the entire circumference of the lower end 78 of the cover 4 abuts against the outermost periphery 72 of the stand 3. The cover 4 in this embodiment is white, and when the cover 4 is completely attached to the stand 3, the iron 2 inside cannot be seen, but the cover 4 may be translucent so that the inside can be seen, or may be of another color. Note that, for convenience of explanation, in FIG. 1, the iron 2 inside the cover 4 and the stand 3 are shown visible from the outside. The outer shape of the cover 4 may also be other shapes.
[0037] Next, we will explain how to use the heat storage device 1. As shown in FIG. 1, the cover 4 is completely attached to the mounting base 3, and then the cover 4 is removed. To use the steam function, open the water inlet lid 14, pour water into the storage chamber 24 of the tank assembly 13 through the water inlet 15, and then close the water inlet lid 14. Next, grasp the power plug 58, pull out the power cord 49, and insert the power plug 58 into a household outlet. When the iron 2 is placed on the mounting base 3 and the power receiving terminal 43 and the power supply terminal 57 are connected, power is supplied to the heater 7, which drives the heater 7 to heat the base 8. When the temperature indicator lamp 23 lights up, indicating that the temperature of the base 8 has reached the set temperature, grasp the handle 6 to remove the iron 2 from the mounting base 3, and begin ironing. The temperature of the base 8 decreases over time. Therefore, when the temperature of the base 8 drops, the iron 2 is placed on the stand 3, and the power receiving terminal 43 is connected to the power supply terminal 57, which supplies power to the heater 7 and heats the base 8. When the temperature of the base 8 reaches the set temperature, ironing is performed. When the ironing operation is completed, the iron 2 is placed on the stand 3 and the power plug 58 is removed from the household outlet. Removing the power plug 58 from the household outlet cuts off the power supply to the stand 3, which also cuts off the power supply to the heater 7 of the iron 2 placed on the stand 3. The heater 7 then stops operating, and heating of the base 8 stops. Thereafter, the power cord 49 is wound onto the cord reel 59 and stored inside the stand 3. Finally, the cover 4 is placed on the iron 2, and the locking portions 76 and 77 are engaged with the locking receiving portions 52 and 53 to completely attach the cover 4 to the stand 3.
[0038] Here, we will explain a case where the cover 4 is incompletely attached to the iron stand 3 when the power plug 58 is plugged into a household outlet and the iron 2 is placed on the iron stand 3 (powered state). If you try to attach the cover 4 to the iron stand 3 with the power plug 58 plugged into a household outlet, the power cord 49 will be pulled out, resulting in the power cord 49 being pinched between the iron stand 3 and the cover 4. This prevents the entire circumference of the bottom end 78 of the cover 4 from abutting against the outermost periphery 72 of the iron stand 3, resulting in the cover 4 being incompletely attached to the iron stand 3. Even in this case, the cover 4 comes into contact with and presses the operating protrusion 65, causing the microswitch 50 to shut off the power supply to the heater 7. Note that by positioning the operating protrusion 65 at a higher position, the power supply to the heater 7 can be shut off even when the cover 4 is incompletely attached.
[0039] As described above, the heat storage device 1 of this embodiment includes the iron 2, the stand 3 on which the iron 2 is placed, and the cover 4 detachably attached to the stand 3. The iron 2 has the heater 7 and the power receiving terminal 43 electrically connected to the stand 3. The stand 3 has the power supply terminal 57 electrically connected to the iron 2 and the power cord 49 with the power plug 58. When the power plug 58 is connected to an outlet and the iron 2 is placed on the stand 3, the power receiving terminal 43 and the power supply terminal 57 are connected, and power is supplied to the heater 7. When the cover 4 is attached to the stand 3, power supply to the heater 7 is cut off. Therefore, by attaching the cover 4 to the stand 3, the operation of the heater 7 can be stopped and heating of the base 8 can be stopped. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, continuous heating of the base 8 can be prevented.
[0040] Furthermore, in the heat storage device 1 of this embodiment, the mounting base 3 is provided with a switch unit 60 that cuts off the power supply to the heater 7. When the cover 4 is attached to the mounting base 3, the cover 4 comes into contact with the switch unit 60, which cuts off the power supply to the heater 7. Therefore, during the process of attaching the cover 4 to the mounting base 3, the cover 4 comes into contact with the switch unit 60, which opens the contacts of the microswitch 50 and cuts off the power supply to the heater 7. In other words, attaching the cover 4 to the mounting base 3 stops the operation of the heater 7 and stops heating of the base 8. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, the base 8 can be prevented from continuing to be heated.
[0041] Furthermore, in the heat storage device 1 of this embodiment, the power cord 49 is drawn out from a cord draw-out section 55 provided on the mounting base 3, and in a plan view, the cord draw-out section 55 is provided on either the left or right side of the mounting base 3 relative to the power feeding terminal 57, and the switch unit 60 is provided on the other side of the power feeding terminal 57. By arranging the cord draw-out section 55 and the switch unit 60 in the spaces on the left and right of the power feeding terminal 57 inside the mounting base 3, respectively, the spaces on the left and right of the power feeding terminal 57 can be effectively utilized, and the external shape of the mounting base 3 can be made symmetrical.
[0042] A power storage device 1A according to a second embodiment of the present invention will be described below with reference to Fig. 7. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. Only the different parts will be described in detail. The power storage device 1A of this embodiment does not include a switch unit 60, but instead has a disconnection section 80 provided inside the cover 4. For ease of description, Fig. 7 shows the iron 2 and iron stand 3 inside the cover 4 so that they can be seen from the outside.
[0043] The disconnecting portion 80 is provided inside the rear end portion of the cover 4. When the iron 2 is placed on the stand 3, the power supply connector 48 is inserted into the connection receptacle 42, and the power receiving terminal 43 and the power supply terminal 57 are connected. In this state, when the cover 4 is placed over the iron 2 from above to attach it to the stand 3, the disconnecting portion 80 comes into contact with the rear end surface 44 of the grip 6. When the cover 4 is further lowered, the rear end surface 44 is pressed against the disconnecting portion 80, and the iron 2 moves forward. When the cover 4 is placed to a predetermined position, the iron 2 moves forward, and the electrical connection between the power receiving terminal 43 and the power supply terminal 57 is released. This cuts off the power supply to the iron 2, stopping the heater 7 from operating and the base 8 from heating.
[0044] In this embodiment, when the cover 4 is lifted and the disconnection portion 80 moves away from the rear end surface 44 of the grip portion 6, the iron 2 moves rearward due to its own weight, the power supply connection portion 48 is inserted into the connection receiving portion 42, and the power receiving terminal 43 and the power supply terminal 57 are connected. However, even when the cover 4 is lifted and the connection releasing portion 80 moves away from the rear end surface 44 of the grip portion 6, the iron 2 may not move and the electrical connection between the power receiving terminal 43 and the power supply terminal 57 may remain disconnected.
[0045] When the cover 4 is placed over the iron 2, as long as the disconnection portion 80 abuts against the rear end surface portion 44 of the grip portion 6 and can press and move the iron 2 forward, the disconnection portion 80 can be formed in the desired shape and can be located in the desired position.
[0046] As described above, the heat storage device 1A of this embodiment includes the iron 2, the stand 3 on which the iron 2 is placed, and the cover 4 detachably attached to the stand 3. The iron 2 has the heater 7 and the power receiving terminal 43 electrically connected to the stand 3. The stand 3 has the power supply terminal 57 electrically connected to the iron 2 and the power cord 49 with the power plug 58. When the power plug 58 is connected to an outlet and the iron 2 is placed on the stand 3, the power receiving terminal 43 and the power supply terminal 57 are connected, and power is supplied to the heater 7. When the cover 4 is attached to the stand 3, power supply to the heater 7 is cut off. Therefore, by attaching the cover 4 to the stand 3, the operation of the heater 7 can be stopped and heating of the base 8 can be stopped. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, continuous heating of the base 8 can be prevented.
[0047] Furthermore, in the heat storage device 1A of this embodiment, when the cover 4 is attached to the mounting base 3, the power receiving terminal 43 and the power supply terminal 57 are disconnected, and power supply to the heater 7 is cut off. Therefore, in the process of attaching the cover 4 to the mounting base 3, the power receiving terminal 43 and the power supply terminal 57 are disconnected, and power supply to the heater 7 can be cut off. In other words, by attaching the cover 4 to the mounting base 3, the operation of the heater 7 can be stopped, and heating of the base 8 can be stopped. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, it is possible to prevent the base 8 from continuing to be heated.
[0048] Hereinafter, a power storage device according to a third embodiment of the present invention will be described with reference to FIG. 8. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. Only the different parts will be described in detail. This embodiment does not include a switch unit 60, but instead includes an illuminance sensor unit 81 on the stand 3. For ease of explanation, FIG. 8 shows the iron 2 and stand 3 inside the cover 4 so that they can be seen from the outside.
[0049] Although not shown, the illuminance sensor unit 81 is disposed at the position where the microswitch 50 of the first embodiment is disposed. The illuminance sensor unit 81 includes an illuminance sensor 82 and a switching means (not shown) for switching on / off the electric circuit of the wiring 64. The illuminance sensor unit 81 is provided midway along the wiring 64.
[0050] The illuminance sensor 82 has a detection section 83 (light receiving section) exposed from the protrusion hole 54, and is capable of detecting the brightness around the mounting table 3.
[0051] In this embodiment, the cover 4 has light-blocking properties at least in the portion covering the detection unit 83. Therefore, when the cover 4 is placed over the iron 2 and the detection unit 83 is covered by the cover 4, and the amount of light detected by the detection unit 83 falls below a predetermined value, the switching means 83 turns off the electrical circuit of the wiring 64, cutting off power to the wiring 64. Therefore, when the power plug 58 is inserted into a household outlet and the power receiving terminal 43 and the power supply terminal 57 are connected, and an attempt is made to attach the cover 4 to the mounting base 3, power to the wiring 64 is cut off, power supply to the heater 7 is stopped, and heating of the base 8 is stopped. When the cover 4 is lifted and the amount of light detected by the detection unit 83 exceeds a predetermined value, the switching means turns on the electrical circuit of the wiring 64, and the wiring 64 becomes electrically conductive. The predetermined value of the amount of light detected by the detection unit 83, which serves as a criterion for switching the electrical circuit on / off, may be determined based on the light-blocking ability of the cover 4, etc.
[0052] In the heat storage device 1B of this embodiment, even if the user does not attach the cover 4, turns off the lights in the room where the energy storage device 1 is placed, and leaves the room, if the room is dark to a certain extent and the amount of light detected by the detection unit 83 is less than a predetermined value, the switching means turns off the electrical circuit of the wiring 64.
[0053] In this embodiment, the rear side of the grip portion 6 is connected to the main body portion 5, which is a so-called closed handle, but it may also be a so-called open handle, in which only the front side of the grip portion 6 is connected to the main body portion 5.
[0054] As described above, the heat storage device 1B of this embodiment includes the iron 2, the stand 3 on which the iron 2 is placed, and the cover 4 detachably attached to the stand 3. The iron 2 has the heater 7 and the power receiving terminal 43 electrically connected to the stand 3. The stand 3 has the power supply terminal 57 electrically connected to the iron 2 and the power cord 49 with the power plug 58. When the power plug 58 is connected to an outlet and the iron 2 is placed on the stand 3, the power receiving terminal 43 and the power supply terminal 57 are connected, and power is supplied to the heater 7. When the cover 4 is attached to the stand 3, power supply to the heater 7 is cut off. Therefore, by attaching the cover 4 to the stand 3, the operation of the heater 7 can be stopped and heating of the base 8 can be stopped. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, continuous heating of the base 8 can be prevented.
[0055] Furthermore, in the heat storage device 1B of this embodiment, the mounting base 3 has an illuminance sensor 82, and when the illuminance detected by the illuminance sensor 82 falls below a predetermined value, power supply to the heater 7 is cut off. Therefore, when the cover 4 is attached to the mounting base 3, the detection unit 83 of the illuminance sensor 82 is covered by the cover 4, and when the illuminance detected by the illuminance sensor 82 falls below the predetermined value, power supply to the heater 7 can be cut off. In other words, attaching the cover 4 to the mounting base 3 stops the operation of the heater 7 and stops heating of the base 8. As a result, even if the power plug 58 is forgotten to be unplugged from the household outlet, the base 8 can be prevented from continuing to be heated.
[0056] The present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the heat storage device main body is not limited to the iron 2, and may be a steamer used to remove wrinkles from clothes hung on a hanger, an iron without a steam ejection function, or the like.
