[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] (Embodiment 1) Hereinafter, an electric device according to the present embodiment will be described with reference to FIGS.

[0011] First, the configuration of the function providing unit in the electrical device will be described with reference to Figures 1 to 4. Figure 1 is a rear perspective view of housing 30 of the electrical device in the embodiment of the present invention, and Figure 2 is a front perspective view of housing 30 of the electrical device. Figure 3 is an exploded perspective view of housing 30 of the electrical device in the embodiment of the present invention, and Figure 4 is a cross-sectional schematic view of housing 30 of the electrical device.

[0012] As shown in FIGS. 1 and 2, the housing 30 of the electrical device includes a box-shaped main body case 1 that forms an outer shell.

[0013] The main body case 1 has an inlet 7, an outlet 8, and a lid 5, and is provided therein with a function providing unit 2, which will be described later.

[0014] The air inlet 7 is an opening for drawing air from the indoor space into the main body case 1, and is provided on the front side of the main body case 1.

[0015] The air outlet 8 is an opening for blowing air from inside the main body case 1 into the indoor space, and is provided on the upper part (top surface) of the main body case 1. A rotatable louver 14 is provided above the air outlet.

[0016] The lid portion 5 is connected to a part of the main body case 1 to open and close the opening, and will be described in detail later.

[0017] The function providing unit 2 provides a predetermined function by receiving power, and in this embodiment provides a function of dehumidifying air drawn in through the air inlet 7 and blowing it out through the air outlet 8 (dehumidifying function).

[0018] Next, the detailed structure of the function providing unit 2 will be described with reference to FIGS.

[0019] The function providing unit 2 provides a predetermined function by receiving power, and includes a blower 9, a dehumidifying means 10, a regeneration unit 11, a water storage unit 12, and an air passage 13. In the present invention, the function providing unit 2 provides a dehumidifying function as a predetermined function, but this may also be an air purification function of an air purifier, and the function is not limited thereto.

[0020] The blower 9 guides air from the inlet 7 to the outlet 8, and is a sirocco fan in the present invention.

[0021] The dehumidifying means 10 has a dehumidifying rotor 15 , a support frame 16 , and a driving means 17 .

[0022] The dehumidifying rotor 15 is disc-shaped, and the central axis of the disc is horizontally and rotatably erected when the dehumidifier is in operation, and is rotated by a driving means 17. The dehumidifying rotor 15 includes a moisture absorbing section 18 and a moisture releasing section 19.

[0023] The moisture absorbing section 18 is a part of the dehumidifying rotor 15 and absorbs moisture from the air passing through the air passage 13 .

[0024] The moisture release section 19 is a part of the dehumidification rotor 15, and releases moisture into the air passing through it.

[0025] Support frame 16 is disposed so as to separate the front side from the back side of main body case 1, and has a circular opening 16a in the center. Dehumidifying rotor 15 is disposed between the back side of main body case 1 and support frame 16, and is rotatable so as to close opening 16a of support frame 16.

[0026] The driving means 17 rotates the dehumidifying rotor 15, and in this embodiment, an electrically driven motor is used.

[0027] The regeneration unit 11 has a circulation air passage 20, a heat generating section 21, a heat exchanger 22, and a circulation fan 23.

[0028] The circulation air passage 20 is an annular air passage that connects the circulation fan 23, the heat generating section 21, the moisture discharging section 19, and the heat exchanger 22 in this order and allows air to pass through.

[0029] The heat generating unit 21 generates heat using an electric heating wire, and is provided in a position facing one side of the moisture discharging unit 19 (the rear side of the main body case 1) in the circulating air passage 20. The heat generating unit 21 heats the moisture discharging unit 19 by generating heat, causing moisture to be discharged from the moisture discharging unit 19 toward the downstream side of the circulating air passage 20.

[0030] The heat exchanger 22 exchanges heat between the air in the circulation air passage 20 containing moisture released from the moisture release section 19 and the air in the air passage 13. The heat exchanger 22 is arranged in the main body case 1 so as to be adjacent to the dehumidification rotor 15 in the horizontal direction.

[0031] The circulation fan 23 is provided between the rear surface of the main body case 1 and the support frame 16, and serves to circulate air within the circulation air passage 20, and is a sirocco fan in the present invention.

[0032] Water storage section 12 is a tank detachably provided below main body case 1, and collects and stores water generated by condensation in air passage 13 and air circulation passage 20.

[0033] Air passage 13 is an air passage that connects inlet 7 and outlet 8, and includes dehumidifying air passage 13a and cooling air passage 13b.

[0034] Dehumidifying air passage 13a is an air passage that connects intake port 7 of main body case 1, moisture discharge section 19, and blower section 9 in this order, and leads to outlet 8. The air drawn in through intake port 7 has moisture adsorbed by moisture discharge section 19, and is dehumidified.

[0035] Cooling air passage 13b is an air passage that connects intake port 7 of main body case 1, heat exchanger 22, and blower unit 9 in this order, and leads to outlet 8. Air in the circulation air passage that passes through heat exchanger 22 is cooled by air drawn in from intake port 7. The air that has passed through dehumidifying air passage 13a and cooling air passage 13b is mixed in blower unit 9 and sent out of the main body case from outlet 8.

[0036] In the above configuration, the dehumidifying function provided by the function providing unit 2 will be described.

[0037] Air from the indoor space drawn into dehumidifying air duct 13a through air inlet 7 by air blower 9 is dehumidified by absorbing moisture in moisture absorber 18. The dehumidified air is then blown into the indoor space through air outlet 8. The moisture absorbed by moisture absorber 18 moves to moisture releaser 19 as dehumidifying rotor 15 rotates, and is then heated by heat generator 21 and released into circulating air duct 20. The moist air released from moisture releaser 19 is blown to heat exchanger 22 by airflow from circulation fan 23. In heat exchanger 22, heat is exchanged between the air in circulating air duct 20 passing through heat exchanger 22 and the air in cooling air duct 13b passing through heat exchanger 22. During this process, the air in circulating air duct 20 is cooled by the air in cooling air duct 13b, causing condensation. The water generated by this condensation is collected and stored in water storage unit 12. The air in cooling air passage 13b, which has cooled heat exchanger 22 and has increased in temperature, is mixed with the air in dehumidifying air passage 13a by blower 9 and is blown into the indoor space from outlet 8. In this way, the air in the indoor space is dehumidified.

[0038] The above is an example of the function provided by the function providing unit 2 included in the electrical device.

[0039] Next, the configuration of power supply storage section 31 will be described with reference to Figures 5 and 6. Figure 5 is a front view of housing 30 of the electrical device in the embodiment of the present invention with the cover removed, and Figure 6 is a cross-sectional view showing the storage space of housing 30 of the electrical device in the embodiment of the present invention.

[0040] The main body case 1 further includes a power supply storage section 31.

[0041] The power supply storage section 31 is composed of components for supplying electricity to the function providing section 2 and a space for storing the components, and includes an opening 4, a storage space section 6, and a power cord 3.

[0042] The opening 4 is provided on the back side, which is a side surface of the main body case 1, and is a vertically long opening extending vertically upward. The opening 4 serves as an entrance to the storage space 6 for the power cord 3. Note that the terms "vertically upward" and "vertically downward," which will be described later, refer to directions when the electrical device is installed and ready for operation.

[0043] The storage space 6 is formed from the opening 4 toward the inside of the main body case 1, and is a box-shaped space with a bottom surface 6a located vertically downward, for storing the power cord 3. The storage space 6 includes a main storage space 6b, a sub-storage space 6c, and a cord storage auxiliary section 6d.

[0044] The bottom surface 6a is a surface provided vertically below the storage space 6, and has a gap 25 between it and the lid 5 so that a covered cord portion (described later) can pass through when the lid 5 is closed.

[0045] Main storage space 6b faces opening 4 and forms a space facing inward of main case 1. Main storage space 6b faces opening 4 and includes opening 4 at the boundary of the space.

[0046] The sub-storage space 6c is connected to the main storage space 6b in the vertically upward direction, but does not face the opening 4. Here, not facing the opening 4 means that an inner wall 28 is disposed on the front side of the sub-storage space 6c. The power cord 3 stored in the storage space portion 6 is partially stored within the sub-storage space 6c.

[0047] The cord storage auxiliary portion 6d prevents the stored power cord 3 from jumping out of the storage space portion 6 through the opening 4, as will be described in detail later.

[0048] The power cord 3 supplies electricity to the function-providing unit 2 by being connected to an outlet provided in the space in which the main body case 1 is used, and includes a plug portion 3a and a covered cord portion 3b. The power cord 3 is installed outside the storage space 6, extending from a predetermined position below the storage space 6 to the outside of the main body case 1, and is fixed to a predetermined position in the main body case 1 by a power cord fixing portion 24.

[0049] The plug portion 3a is provided at one end of the covered cord portion 3b and has a terminal that can be connected to an outlet. When the plug portion 3a is connected to an outlet, it transmits electricity to the covered cord portion 3b.

[0050] The coated cord portion 3b is a cable having one end connected to the plug portion 3a and the other end connected to a power supply board (not shown) that distributes electricity to the function providing portion 2. The coated cord portion 3b is composed of a core wire (not shown) and a coating 3c.

[0051] The core wire is a conductive wire that connects the plug portion 3a to the power supply board.

[0052] The covering 3c is made of an insulating material and covers the core wire to protect the core wire and prevent the user from getting an electric shock.

[0053] Next, the lid portion in this embodiment will be described.

[0054] The lid 5 is detachable from the edge of the opening 4, and opens and closes the opening 4 by attaching and detaching it (detachable system). When the lid 5 opens the opening 4, the main storage space 6b appears without exposing the sub-storage space 6c, and the power cord 3 can be stored in and removed from the storage space 6.

[0055] Next, an example of the configuration of the cord storage assisting portion 6d that prevents the stored power cord 3 from jumping out of the storage space portion 6 through the opening 4 will be shown.

[0056] In this embodiment, the cord storage auxiliary portion 6d is a jump-out prevention rib 26 that is provided in the main storage space 6b including the opening 4 and prevents the power cord 3 from coming into contact with the lid portion 5.

[0057] As shown in Figure 5, the protrusion prevention rib 26 is generally plate-shaped and is located on the same plane as the opening 4 and slightly below the center of the opening 4 in the height direction. More specifically, the protrusion prevention rib 26 extends a predetermined distance from the side edge of the opening 4 that forms the periphery of the opening 4 inside the lid 5 toward the other side edge, and a passage space 29 wide enough to allow the power cord 3 to pass through is maintained between the tip of the protrusion direction and the other side edge. This restricts the power cord 3 from passing through a portion of the opening 4.

[0058] In the above configuration, the procedure for storing the power cord 3 in the storage space 6 will be described.

[0059] First, the power cord 3 is folded and bundled to a length that can be stored in the storage space 6. Here, the "storable length" refers to a length that is equal to or less than the combined height of the main storage space 6b and the sub-storage space 6c, but is equal to or greater than the height of the main storage space 6b. When folding, the power cord 3 is pre-formed so that it can be folded to the appropriate length, making it easy to identify the appropriate position for folding. Next, the bundled power cords 3 are inserted into the storage space 6 through the opening 4, which is opened by the lid 5. At this time, the upper ends of the bundled power cords 3 are inserted a predetermined distance into the sub-storage space 6c. The power cords 3 are inserted into a position of the opening 4 that is not blocked by the anti-jump rib 26, i.e., through the aforementioned passage space 29. Next, the bundled power cords 3 are moved horizontally to a position facing the plane of the anti-jump rib 26 (the left side in Figure 5). Finally, the opening 4 is closed by the lid 5. At this time, the covered cord portions 3b extend into and out of the storage space 6 through the gap 25.

[0060] Next, a mechanism for preventing the power cord 3 from jumping out of the storage space 6 will be described.

[0061] As described above, the power cord 3 is stored in a folded bundle within the storage space 6. The folded power cord 3 tends to unfold due to elastic force, and if not prevented from protruding, it will protrude out of the storage space 6 through the opening 4 opened by the lid 5. In the present invention, the power cord 3 is stored in a position facing the protrusion prevention rib 26. As a result, the power cord 3, which unfolds due to elastic force, comes into contact with the protrusion prevention rib 26 and is prevented from protruding. Furthermore, because the sub-storage space 6c does not face the opening 4 and has an inner wall 28, a portion of the power cord 3 stored in the sub-storage space 6c is prevented from protruding by the inner wall 28 on the rear side of the sub-storage space 6c, even if it unfolds due to elastic force. As described above, protrusion out of the storage space 6 is prevented at two points: the protrusion prevention rib 26 and the inner wall 28 of the sub-storage space 6c. This makes it possible to provide a housing 30 for electrical equipment that prevents the power cord 3 from protruding.

[0062] Next, the procedure for removing the power cord 3 from the storage space 6 will be described.

[0063] First, the opening 4 is opened by the lid 5. Next, the bundled power cords 3 are moved horizontally to a position not facing the anti-dropout rib 26. Next, the bundled power cords are removed from the storage space 6 through the passage space 29 of the opening 4.

[0064] As described above, the power cord 3 stored in the storage space 6 can be removed simply by moving it horizontally to a position that is not facing the protrusion-prevention rib 26. This makes it possible to provide a housing 30 for electrical equipment that prevents the power cord from protruding and allows for easier storage and removal.

[0065] Furthermore, when the opening is closed with the lid 5, if the power cord 3 expands due to its elastic force and comes into contact with the lid 5, the lid 5 may come off and the power cord 3 may fly out of the opening 4. In the present invention, the jump-out prevention rib 26 is located in the opening 4 or in the main storage space 6b inside the opening 4, so the power cord 3 will not come into contact with the lid 5 when it expands due to its elastic force. This makes it possible to provide a housing 30 for electrical equipment that can further prevent the power cord 3 from flying out.

[0066] Next, a configuration that takes into consideration even greater safety when storing the power cord will be described with reference to FIG.

[0067] FIG. 7 is a partially enlarged cross-sectional view of the storage space of the housing of the electrical device according to the embodiment of the present invention.

[0068] If the load caused by bending of covered cord portion 3b exceeds a certain value, the core wire may break, causing a failure in which electricity cannot be supplied to function-providing portion 2. Breaking of the core wire may lead to several unsafe situations, such as fire. In this embodiment, covered cord portion 3b is stored in storage space portion 6 via gap 25, and the closer gap 25 is to a predetermined position extending outside main body case 1, the more acute the bending angle becomes, and the greater the load caused by bending.

[0069] To prevent the above-mentioned unsafe situation, it is desirable that gap 25 be located at a length such that the load applied to the bent portion of covered cord portion 3b when power cord 3 is stored through gap 25 into storage space 6 is below a certain value. The bent portion refers to a portion located between the predetermined position and gap 25. The certain value is a value smaller than the load applied to the bent portion when gap 25 is located at a radius of 38 mm from the predetermined position and at an angle of 25 degrees from the horizontal, for example.

[0070] With the above configuration, it is possible to provide a housing 30 for an electric device that is capable of suppressing breakage of the core wire and improving safety.

[0071] Moreover, it is desirable that the shape of one end 27 of the bottom surface 6a facing the lid portion 5 is an arc.

[0072] When covered cord portion 3b is stored in storage space 6 through gap 25, it comes into contact with one end 27 that faces lid 5. By making one end 27 a rounded arc, the shape of covered cord portion 3b passing through gap 25 can be made to be similarly rounded to the arc. This makes the bending angle of covered cord portion 3b relatively gentler than when one end 27 has a non-rounded shape.

[0073] With the above configuration, it is possible to provide a housing 30 for an electric device that is capable of suppressing breakage of the core wire and improving safety.

[0074] The present invention has been described above based on an embodiment. This embodiment is merely illustrative, and those skilled in the art will understand that various modifications are possible in the combination of each component or each processing step, and that such modifications are within the scope of the present invention. In the above-described embodiment, design changes that are possible are described using phrases such as "in the embodiment" or "in the embodiment." However, this does not mean that design changes are not permitted in areas without such phrases. In particular, in this embodiment, the power cord 3 may extend from inside the storage space 6 to outside the main case 1, which is a matter of discretion for the practitioner of the invention. Furthermore, in this embodiment, the power cord 3 may be a door-type device that opens and closes by drawing an arc around a hinged portion, which is a matter of discretion for the practitioner of the invention. [Industrial Applicability]

[0075] It is expected to be used to store power cords in the housings of household electrical appliances. [Explanation of symbols]
