Description

  The present invention relates to the drying technology of sanitary washing, in particular to a washing apparatus comprising a drying device and a drying device.

  2. Description of the Related Art Conventionally, a sanitary washing device for washing a local part or the like of a human body has various functions in order to realize local washing according to the preference of the user. These sanitary cleaning devices allow the user to perform comfortable local cleaning.

  However, usually, after washing the local area, the user must use toilet paper to remove water droplets and the like adhering to the local area. Therefore, in recent years, a sanitary washing device having a drying function has been disclosed which removes water droplets adhering to local parts without using toilet paper (see, for example, Patent Documents 1 and 2).

  The sanitary washing device disclosed in Patent Document 1 will be described below with reference to FIG.

  FIG. 1 is a schematic perspective view of the sanitary washing device disclosed in Patent Document 1. As shown in FIG. Patent Document 1 discloses a sanitary washing device having a washing device for jetting washing water and a drying device for blowing warm air.

  Specifically, as shown in FIG. 1, the sanitary washing device 11 of Patent Document 1 includes a washing device 13 and a drying device 14 and the like, and is placed on the toilet bowl 12.

  Then, when using the sanitary washing device 11, first, the washing device 13 spouts washing water for washing a local part of the human body. When the washing is completed, warm air is blown out of the drying device 14. As a result, water droplets and the like adhering to the local area are removed to dry the local area of the human body.

  Hereinafter, the sanitary washing device disclosed in Patent Document 2 will be described with reference to FIG.

  FIG. 2 is a schematic view of a drying apparatus disclosed in Patent Document 2. As shown in FIG. Patent Document 2 discloses a drying apparatus.

  Specifically, as shown in FIG. 2, the drying device 40 of Patent Document 2 includes a blower fan 41, a warm air heater 44, and the like. That is, the drying device 40 accelerates the gas flowing in from the A0 direction by the blower fan 41 and causes the gas to flow into the warm air heater 44. The inflowing gas is heated by the warm air heater 44. Then, the heated gas is sent out from the air outlet 42 through the air flow path 43 in the A2 direction.

  In this case, in order to prevent the washing water from flowing into the warm air heater 44 through the air flow path 43, it is necessary to seal the air flow path 43 entirely when the drying device 40 is not operating. Therefore, in the conventional drying device or the like, a waterproof shielding plate is installed in the air passage 43.

  Below, the structure of the waterproof shielding board in the conventional drying apparatus is demonstrated using FIG. 3 and FIG.

  FIG. 3 is a schematic cross-sectional view of the conventional drying apparatus having a waterproof shielding plate at the time of stopping. FIG. 4 is a schematic cross-sectional view during operation of a conventional drying apparatus having a waterproof shielding plate.

  The drying device 300 shown in FIGS. 3 and 4 includes a blower 302, a heater 303, a waterproof shielding plate 304, and the like in a case 301. The waterproof shielding plate 304 is composed of a single plate-like assembly. That is, the waterproof shielding plate 304 has a size corresponding to the cross section of the air passage 305 at the position where the waterproof shielding plate 304 is provided. Therefore, when the height of the air passage 305 at the portion where the waterproof shielding plate 304 is located is L, the length of the waterproof shielding plate 304 also needs to be at least about L.

  Next, the operation and action of the waterproof shielding plate in the conventional drying device will be specifically described.

  First, as shown in FIG. 3, when the drying device 300 is stopped, the waterproof shielding plate 304 contacts the upper wall 305 a and the lower wall 305 b of the air passage 305 to thereby seal the entire air passage 305. This prevents the washing water from flowing into the heater 303 from the outlet 3011 of the drying device 300.

  On the other hand, as shown in FIG. 4, at the time of operation of the drying device 300, the waterproof shielding plate 304 is pivoted to the blowout port 3011 side about the pivot shaft 304 a and opened toward the upper wall 305 a of the air passage 305. Be done. That is, the waterproof shielding plate 304 is in close contact with the upper wall 305 a of the air passage 305. As a result, the warm air blown from the blower 302 and heated by the heater 303 flows from the blower passage 305 and reaches the blower outlet 3011. Then, the warm air blown out from the blowout port 3011 dries the local part of the human body.

  However, the conventional drying apparatus 300 needs to completely open the waterproof shielding plate 304 in order to smoothly flow the gas into the air passage 305 during operation. Further, as shown in FIG. 4, when the waterproof shielding plate 304 is opened, it is necessary to accommodate the waterproof shielding plate 304 of size L in the air flow path 305 between the waterproof shielding plate 304 and the outlet 3011. Therefore, the length of the air flow path 305 from the rotation axis 304a of the waterproof shielding plate 304 to the outlet 3011 needs to be at least a length L 'equivalent to the size L of the waterproof shielding plate 304 projected from above. There is. Therefore, in the conventional drying device 300, the length of the air passage 305 is increased.

  However, with the recent demand for downsizing of the sanitary washing device, it has been an issue how to shorten the length of the air passage 305.

  Moreover, since the waterproof shielding board 304 of the drying apparatus 300 shown in FIG. 4 is comprised by one sheet, a volume is large and a weight also becomes large. Therefore, in order to open the waterproof shielding plate 304, a considerably large wind force (for example, a thrust generated by high-speed warm air) is required. As a result, the energy consumption of the blower 302 is increased. That is, there was a problem in energy saving of the sanitary washing device and the drying device.

JP 2005-139619 A Chinese Patent Application Publication No. 102084070

  The present invention provides a sanitary washing device that is compact and has a drying device and a drying device that can suppress energy consumption.

  That is, the drying apparatus according to the present invention includes a case having an air flow path for guiding a flow of gas and an outlet for discharging the gas, a fan installed in the case, an air flowr accelerating and flowing the gas toward the outlet. It has a heater for heating the gas accelerated by the blower and a waterproof shielding plate composed of at least two plate members provided on the outlet side in the air passage.

  According to this configuration, the waterproof shielding plate of the drying device is configured by at least two plate members. Thereby, the length of the ventilation path which accommodates a waterproof shielding board can be shortened. As a result, the length of the drying device can be shortened, and downsizing of the drying device can be realized. In addition, by configuring the waterproof shielding plate with two plate members, the individual weight and the overall weight can be made lighter than the conventional waterproof shielding plate. Therefore, it is possible to open the waterproof shield with a small wind force and open the air passage. As a result, a drying device excellent in energy saving can be realized.

  The sanitary washing device of the present invention also includes a base fixedly connected to the toilet bowl body, the above-described drying device fixed to the base and drying the washing water, and a body cover covering the base and the drying device. As a result, it is possible to realize a sanitary washing device which is compact and excellent in energy saving.

Embodiment 1
Hereinafter, the configuration of the drying device according to the first embodiment of the present invention will be described with reference to FIG.

  FIG. 5 is a schematic cross-sectional view at the time of stop of the drying device in the first embodiment of the present invention. In addition, in FIG. 5, in order to clarify an understanding of the drying device 500, only the main components of the drying device 500 are shown. Therefore, the specific structure of the other member of the drying device 500 and each member is omitted. For example, the specific configuration of the heater 503 is not shown.

  As shown in FIG. 5, the drying device 500 according to the present embodiment includes a case 501 having a blower passage 5011 for guiding the flow of gas and a blower outlet 5012 for letting the gas flow out, and a blower 502 installed in the case 501. , A heater 503, a waterproof shielding plate 504, and the like.

  The outlet 5012 of the case 501 is provided on the front end side (right side in FIG. 5) of the case 501.

  The blower 502 is disposed on the rear end side (left side in FIG. 5) of the case 501, and accelerates the gas to flow toward the blowout port 5012. The blower 502 may be configured to have, for example, a plurality of shift speeds corresponding to different wind speeds, or a continuously variable transmission function. Thereby, the user can cause the drying device to output at different wind speeds as needed to dry the local part of the human body. As a result, it is possible to realize a drying device excellent in the feeling of use.

  The heater 503 is disposed closer to the front end (the outlet 5012) of the case 501 than the blower 502, and heats the gas accelerated by the blower 502. The specific configuration of the heater 503 will be described later with reference to FIGS. 7 and 8.

  The waterproof shielding plate 504 is disposed between the blowout port 5012 and the heater 503 in the air flow path 5011 of the case 501, and includes at least two plate-like members 5041 and 5042. Then, the waterproof shielding plate 504 prevents the liquid such as the cleaning liquid from flowing into the heater 503 from the blowout port 5012.

  In the present embodiment, the waterproof shielding plate 504 will be described as an example composed of two plate members, but the present invention is not limited to this. The waterproof shielding plate 504 may be configured of, for example, N (N> 2) plate members in accordance with the use of the drying device 500, the shape, the wind force of the blower 502, and the like.

The waterproof shielding plate 504 of the present embodiment is composed of a plate-like member 5041 of length l _{1 and} a plate-like member 5042 of length l ₂ and is sequentially arranged in the vertical direction of the air passage 5011. Is provided. In this case, the length _{l 1} of the plate member 5041, the length of each of length _{l 2} of the plate-like member 5042, the height L of the air passage at the position of the air passage 5011 waterproof shield plate 504 is installed Less than. However, being arranged in order in the vertical direction, the sum of the lengths l ₂ of the length l ₁ and the plate-like member 5042 of the plate-like member 5041 is greater than the height L of at least air passage. That is, it has a length that satisfies the relationship of L <l ₁ + l ₂ . Thereby, the ventilation path 5011 of height L can be shielded reliably. Although the depth of the waterproof shielding plate 504 in FIG. 5 is not particularly described, any shape may be used as long as the cross section of the air passage 5011 can be shielded.

  Hereinafter, the operation of the drying apparatus 500 according to the present embodiment will be described with reference to FIG. 5 and using FIG.

  6 is a schematic cross-sectional view of the drying device shown in FIG. 5 in operation. Arrow A shown in FIG. 6 indicates the flow direction of the air flow.

  Further, while the drying device 500 is stopped, as shown in FIG. 5, the two plate-like members 5041 and 5042 constituting the waterproof shielding plate 504 are suspended, and the air passage 5011 is closed. As a result, the air passage 5011 behind the waterproof shielding plate 504 is closed. Therefore, even when water intrudes from the blowout port 5012, the waterproof shielding plate 504 can prevent penetration into the back. Further, the waterproof shielding plate 504 can prevent occurrence of an abnormality such as a short circuit due to the heater 503 and the blower 502 installed at the back side being flooded.

  When the drying device 500 is operated, the plate-like members 5041 and 5042 are as shown in FIG. 6 from the closed state of the air passage 5011 by the two plate-like members 5041 and 5042 constituting the waterproof shielding plate 504 shown in FIG. It opens by the air flow generated by the blower 502. Thus, the air flow path 5011 is opened, and the air flow is sent from the air flow path 5011 to the air outlet 5012.

At this time, as shown in FIG. 6, lengths projected from the upper side formed in the horizontal direction of the opened plate members 5041 and 5042 are l ′ ₁ and l ′ ₂ . Thus, in the air blowing passage 5011, the length to be secured in advance in the horizontal direction to accommodate the plate-like members 5041 and 5042 may be equal to or longer than the longer one of l' _{1 and} l' ₂ . This length is shorter than the horizontal projection length L 'of the waterproof shielding plate 304 of the conventional drying device shown in FIG. As a result, the length of the air passage 5011 can be shortened.

  Furthermore, the size of each of the waterproof shielding plates 504 can be made relatively smaller than that of the conventional waterproof shielding plates by forming the waterproof shielding plate 504 with the two plate members 5041 and 5042. Therefore, each weight is lighter than the waterproof shielding plate 304 shown in FIG. Thereby, even in the case of a small wind force where the airflow is weak, the waterproof shielding plate 504 can be easily opened. That is, for example, even when the output of the blower 502 is small and the blowing speed of the air flow is slow, the waterproof shielding plate 504 can be easily opened. As a result, energy saving of the drying device 500 can be realized.

  Next, the configuration of the drying device of another example 1 of the present embodiment will be described using FIG. 7.

  FIG. 7 is a cross-sectional view at the time of stop of the drying device of another example 1 in the same embodiment.

  As shown in FIG. 7, the drying device 600 of another example 1 differs from the drying device 500 in that a drying shield plate 505 is further provided in the vicinity of the outlet 5012 to open or cover the outlet 5012. . The other configurations and operations are the same as those of the drying device 500, and thus the description thereof is omitted.

  That is, as shown in FIG. 7, when the drying device 600 is stopped, the drying shielding plate 505 covers the blowout port 5012 and the waterproof shielding plate 504 closes the entire air passage 5011. Therefore, the drying shielding plate 505 also has a waterproofing effect, like the waterproof shielding plate 504. As a result, in combination with the waterproof shielding plate 504, the drying shielding plate 505 can more effectively prevent the cleaning liquid from flowing from the outside through the air passage 5011 and flowing into the heater 503.

  Hereinafter, the operation of the drying device 600 according to the present embodiment will be described with reference to FIG. 7 and using FIG.

  FIG. 8 is a schematic cross-sectional view of the drying device shown in FIG. 7 during operation. Arrow B shown in FIG. 8 indicates the flow direction of the air flow.

  When the drying device 600 is operated, as shown in FIG. 8, from the closed state of the air passage 5011 by the two plate members 5041 and 5042 constituting the waterproof shielding plate 504 shown in FIG. 7 and the drying shielding plate 505. 5041 and 5042 and the drying shielding plate 505 are opened by the air flow generated by the blower 502. Thus, the air passage 5011 is opened to the outside, and the air flow is sent out from the outlet 5012 of the air passage 5011 to the outside.

  In this case, similar to the waterproof shielding plate 504, the drying shielding plate 505 is closed and opened by the own weight of the drying shielding plate 505, and is opened by air flow. The drying shield plate 505 may be closed and opened by a motor drive, an electromagnetic drive, a mechanical drive, or a combination thereof. Thereby, the drying shielding plate 505 can be reliably opened and closed.

  Also, the dry shielding plate 505 may be formed of a material such as PP (polypropylene) using the same material as the waterproof shielding plate 504. Also, the dry shield plate 505 may be formed of a material such as ABS using a different material.

  Moreover, although the said embodiment demonstrated the example which comprised the drying shielding board 505 by the member of 1 sheet, it is not restricted to this. For example, as with the waterproof shielding plate 504, it may be configured of two or more members.

  Here, an example of the configuration of the heater 503 in the drying device according to each of the above-described embodiments will be specifically described with reference to FIGS. 7 and 8.

  As shown in FIGS. 7 and 8, the heater 503 is constituted of, for example, a resistance wire 5031 for generating heat, and heats the gas flowing through the heater 503. The resistance wire 5031 may be disposed in a spiral shape in which the axial direction is along the direction of the air flow. The resistance wire 5031 may be arranged in a mesh on a plane perpendicular to the direction of the air flow. Furthermore, the resistance wire 5031 is not limited to the above-described two types of arrangement shapes, and may be another arrangement shape generally used in this field, as long as it has a shape and configuration capable of heating a gas.

  At this time, the drying device may be provided with an output adjusting unit that adjusts the output of the heater 503. The output adjustment unit adjusts, for example, the current flowing through the resistance wire 5031 to control the heat generation output of the resistance wire 5031. Thereby, even if, for example, the flow velocity of the gas changes, the temperature of the air flow delivered from the blowout port 5012 can be arbitrarily adjusted to be constant.

  Further, the output adjustment unit may be configured to simultaneously control the heat generation output of the resistance wire 5031 and the wind speed of the blower 502. Thereby, warm air which combined different wind speed and temperature is easily realizable. As a result, it is possible to realize a drying device that can obtain a higher feeling of use according to the preference of the user.

  Further, as shown in FIG. 7 and FIG. 8, the drying device of the present embodiment has a configuration in which a heat insulating member 5032 such as a mica plate is installed on the outer periphery of the heater 503 to cover the outside of the resistance wire 5031. It is also good. Thus, the resistance wire 5031 to be heated can be fixed and safety can be enhanced.

  In addition, regarding the heater 503, although the drying apparatus 600 was demonstrated to the example, it can not be overemphasized that it is the same also with the drying apparatus 500. FIG. Furthermore, although not described, it goes without saying that the same applies to the drying apparatus described below.

  Next, the configuration of the drying device of another example 2 of the present embodiment will be described using FIG.

  FIG. 9 is a schematic exploded perspective view of the drying device of another example 2 in the same embodiment.

  As shown in FIG. 9, the drying device 700 of another example 2 differs from the above-described drying device in that the case 501 is composed of two parts, upper and lower in the vertical direction.

  In this case, the upper and lower two parts of the case 501 are engaged by, for example, a clasp. Alternatively, the two upper and lower parts can be connected by, for example, rivets or screws. Furthermore, the joining portions of the upper and lower two parts of the case 501 may be joined by, for example, a gasket (not shown), or an application material such as a sealant may be applied and joined. Thus, air leakage from the joint portion of the air flow path 5011 formed by the two-part case 501, and intrusion of moisture and the like from the outside into the case 501 can be prevented. As a result, energy consumption due to leakage can be saved, and damage to the electronic circuit or mechanical structure inside the case 501 due to the entering moisture can be prevented more reliably.

  In addition, although said drying apparatus 700 demonstrated the example which divides | segments and joins case 501 up and down, it is not restricted to this. For example, the case 501 may be configured to be divided and coupled to the front and back portions shown in FIG. Also, the case 501 may be configured to be divided and coupled to the left and right portions shown in FIG. Furthermore, the case 501 may be formed of a plurality of assembly parts, and each assembly part may be coupled, and any structure can be adopted as long as the case 501 can be formed.

  Further, as in the drying device 700 shown in FIG. 9, an air flow guide member 5013 formed of one or more ribs or the like may be installed in the air flow path 5011 of the case 501. Thereby, the direction of the air flow which flows out out of the inside of the ventilation path 5011 can be controlled.

  In this case, the air flow guide member 5013 is installed in accordance with the actually required air flow direction, such as the upper wall 5011a (corresponding to FIG. 9), the lower wall 5011b and / or the side wall 5011c of the air passage 5011, for example. At this time, the air flow guide member 5013 needs to be disposed at a position that does not prevent the opening of the waterproof shielding plate 504. For example, when the air flow guide member 5013 is disposed at a position too close to the waterproof shielding plate 504, the opening of the waterproof shielding plate 504 is prevented, and a part of the effective opening surface of the air passage 5011 is blocked. Therefore, the flow of the air flow is hindered.

  In addition, although the said drying apparatus 700 demonstrated the example which provided the air flow guide member 5013 in the blowing outlet 5012 vicinity of the ventilation path 5011, it is not restricted to this. For example, the external shape of the case 501 may control the flow of the air flow. Specifically, as shown in FIG. 7 or FIG. 8, the cross section of the air passage 5011 of the drying device may be shaped so as to gradually shrink, for example, like a reverse horn structure along the direction toward the outlet 5012. Good. Accordingly, the air flow can be gradually converged toward the blowout port 5012 to increase the wind speed blown out from the blowout port 5012. As a result, it is possible to further improve the drying effect of the human body part by the drying device.

  Further, as in the drying device 600 shown in FIG. 8, the lower wall 5011 b of the air passage 5011 may have a shape of an inclined surface 5014 (indicated by an oval broken line). Specifically, the inclined surface 5014 is formed to be gradually inclined downward along the direction toward the outlet 5012. Thereby, when the operation of the drying device 600 is stopped, the inclined surface 5014 can block the flow of the liquid from the blowout port 5012 into the air flow path 5011 to some extent. Furthermore, in the operating state of the drying device 600, the water and air remaining in the air passage 5011 can be discharged to the outside according to the flow of the air flow by the inclined surface 5014.

  Thus, the drying device having the various configurations of the present embodiment can be obtained.

  Although different configurations have been described above taking the individual drying devices as an example, it goes without saying that the above configurations may be mutually incorporated to configure the drying devices. Thereby, the same effect can be obtained.

  Below, the waterproof shielding board 504 of the drying apparatus in this Embodiment is demonstrated in detail.

  As described above, each drying device of the present embodiment heats the gas blown by the blower 502 in the process of flowing through the heater 503. The heated gas flows into the air passage 5011 via the waterproof shielding plate 504.

And in this Embodiment, as shown to FIGS. 5-8, the waterproof shielding board 504 is comprised from the plate-shaped member 5041,5042 of at least 2 sheets. The plate-like members 5041 and 5042 are vertically installed, for example, in the vertical direction in the air flow path 5011. At this time, the length along the vertical direction of the plate-like member 5041,5042, as described above, respectively _{l 1} and _{l 2.}

In the present embodiment, equal lengths _{l 1} and _{l 2} of the plate-like member 5041,5042 is configured further, for example, the same material such as PP or ABS. Thus, the operation when the two plate members 5041 and 5042 constituting the waterproof shielding plate 504 are opened can be made the same. As a result, the operation efficiency of the waterproof shielding plate 504 can be enhanced. The two plate members 5041 and 5042 may be made of different materials or may have different heights (lengths) as needed. However, it is more preferable that the plate-like members 5041 and 5042 be equal in length and made of the same material in terms of operation stability and the like.

  Next, the specific configuration and operation of the waterproof shielding plate 504 of the present embodiment will be described using FIG. 10 with reference to FIG.

  FIG. 10 is a schematic perspective view of the waterproof shielding plate in the same embodiment.

  As shown in FIG. 10, there is no gap between the plate-like member 5041 and the plate-like member 5042 in the closed state of the waterproof shielding plate 504 in order to close the whole air flow path 5011 (see FIG. 6 etc.) Will be installed. At this time, the plate-like member 5041 and the plate-like member 5042 are disposed so that there is no gap between the upper wall 5011 a and the lower wall 5011 b of the air passage 5011.

That is, as shown in FIG. 10, the plate members 5041 and 5042 are arranged so as to have overlapping portions that partially overlap in the closed state. Therefore, the sum of the length _{l 2} of the length _{l 1} and the plate-like member 5041 of the plate-like member 5041, larger configuration than the height L of the opening of the air passage 5011 is essential. Thereby, the sealing performance between the plate-like members 5041 and 5042 can be secured.

  The plate-like members 5041 and 5042 are respectively provided with rotation shafts 5043 and 5044 so as to be freely pivotable between the closed state and the open state. The rotating shafts 5043 and 5044 are installed at a position recessed from the outlet 5012 so that the free ends of the plate members 5041 and 5042 do not protrude from the outlet 5012 when the plate members 5041 and 5042 are open. ing.

  At this time, the rotation shaft 5043 of the plate member 5041 is provided in proximity to the upper wall 5011 a of the air passage 5011, and the rotation shaft 5044 of the plate member 5042 is provided at the middle position of the air passage 5011 in the vertical direction. .

  The rotation shaft 5043 of the plate member 5041 and the rotation shaft 5044 of the plate member 5042 are provided on the same vertical line. In addition, if it is possible to close the air passage, it does not have to be on the vertical line, but in order to close it by its own weight, the rotary shaft 5044 of the plate member 5042 Preferably, it is provided at the side position.

  By providing the waterproof shielding plate 504 having the above configuration, the two plate members 5041 and 5042 are disposed in a suspended state only by their own weight when the drying device is stopped, and the air flow path 5011 is closed. The back side (heater 503 installation side) can be held closed. On the other hand, when the drying apparatus is activated, the wind force of the air flow generated by the blower 502 blows up the two plate members 5041 and 5042 in the direction of the upper wall 5011 a of the air passage 5011 and the air passage 5011 is opened.

  In the present embodiment, although the example in which the waterproof shielding plate 504 is opened by air flow has been described, the present invention is not limited thereto. For example, an electric device, an electromagnetic drive device, a mechanical transmission device, or the like may be installed on the two plate members 5041 and 5042. As a result, when the drying device is stopped, the two plate members 5041 and 5042 can be closed by electromagnetic force, mechanical force or their combination, and the air passage 5011 can be closed more reliably. Further, when the drying device is started, the two plate members 5041 and 5042 can be opened by motor driving force, electromagnetic force, mechanical force or a combination thereof, and the air passage 5011 can be more reliably opened. it can.

  Further, in the present embodiment, the constituent material of the waterproof shielding plate 504 is not particularly mentioned, but it is preferable to use a material such as a heat resistant thermoplastic resin which is not easily deformed at high temperature. Thus, it is possible to suppress thermal deformation and the like due to the heat air flow (warm air) received by the two plate members 5041 and 5042 when the drying device operates. As a result, the reliability and durability of the waterproof shielding plate 504 can be improved.

  Furthermore, as the material of the two plate members 5041 and 5042, it may be made of a material that is lightweight, maintains a certain rigidity, and has a high heat resistant temperature, such as aluminum. Thereby, when the two plate-like members 5041 and 5042 are in the open state, it is possible to suppress deformation due to the heat flow (warm air).

  In addition, as a constituent material of the waterproof shielding plate 504, for example, a material such as a carbon fiber material may be configured to be light in weight so that the two plate members 5041 and 5042 can be easily opened only by the wind force of the air flow. Thereby, the two plate members can be reliably opened by the wind force of the air flow.

  That is, when the waterproof shielding plate 504 is specifically produced, it is preferable to comprehensively consider the above-described elements and determine the specific configuration and material of the plate-like member according to the surrounding environment and use conditions. .

  Next, the configuration of the drying device of another example 3 of the present embodiment will be described with reference to FIGS. 11, 12 and 13. FIG.

  FIG. 11 is a cross-sectional view for explaining a state in which the waterproof shielding plate is erroneously attached in the drying device according to the above-described present embodiment.

  That is, as described above, in the drying device of the present embodiment, the waterproof shielding plate is configured of at least two plate members. Therefore, when assembling a waterproof shielding board in a drying apparatus, as shown in FIG. 11, it may happen that two plate members 5041 and 5042 are attached so as to overlap in reverse. Specifically, as shown in FIG. 11, the free end 5041a of the plate member 5041 of the waterproof shielding plate 504 is erroneously on the upstream side (heater 503 side) of the air flow with respect to the rotation shaft 5044 of the plate member 5042. It may be incorporated in the deployed state. When the drying apparatus is operated in such a manner, the plate member 5041 abuts on the rotation shaft 5044 of the plate member 5042 and can not be opened. As a result, for example, the upper half of the air flow path 5011 is blocked, and the required amount of air flow can not be sent to the outside, so that the predetermined drying performance can not be exhibited.

  Therefore, in the drying device of another example 3 of the present embodiment, each of the above-described embodiments is provided with a reverse installation preventing member that prevents at least two plate members from being attached in the opposite direction in the case. It is different from the drying device of. Other configurations, operations, and the like are similar to those of the above-described embodiments.

  Below, the structure of the specific drying apparatus of another example 3 in this Embodiment is demonstrated using FIG. 12 and FIG.

  FIG. 12 is a schematic cross-sectional view of a drying device of another example 3 in the same embodiment. FIG. 13 is a schematic perspective view of the main part of the case of the drying apparatus shown in FIG. Note that FIG. 13 shows only the case 501 of a portion provided with the reverse attachment preventing member 5045 in a simplified manner for the sake of understanding.

  As shown in FIGS. 12 and 13, the drying device 1100 of another example 3 of the present embodiment is an inner surface of the side wall 5011 c of the case 501 of the air passage 5011 on the upstream side of the plate member 5042. The reverse attachment preventing member 5045 made of a plate-like rib is installed to a position higher than the free end 5041 a of the plate member 5041 in a suspended state from the lower end. As a result, the space between the heater 503 and the waterproof shielding plate 504 is occupied by the reverse attachment preventing member 5045. Therefore, in the arrangement shown in FIG. 11, the free end 5041 a of the plate member 5041 can not be installed on the heater 503 side. That is, as shown in FIG. 12, the plate-like member 5041 can always be set in the correct direction in which the free end 5041 a of the plate-like member 5041 becomes the outlet 5012. As a result, the reverse attachment of the plate member 5042 of the waterproof shielding plate 504 can be prevented.

  Hereinafter, the configuration of the drying device of another example 4 in the present embodiment will be described with reference to FIGS. 14 and 15.

  FIG. 14 is a schematic cross-sectional view of the drying device of another example 4 in the same embodiment. FIG. 15 is a schematic perspective view of the main part of the case of the drying apparatus shown in FIG. FIG. 15 shows only the case 501 of the portion provided with the reverse attachment preventing member 5045 in a simplified manner for the sake of understanding.

  That is, as shown in FIG. 14, the drying device 1400 of another example 4 is different from the drying device 1100 of the other example 3 in that it is constituted by a convex rib having a circular cross section as the reverse installation preventing member 5045. .

  Furthermore, the structure of the drying apparatus of another example 5 in this embodiment is demonstrated using FIG. 16 and FIG.

  FIG. 16 is a schematic cross-sectional view of the drying device of another example 5 in the same embodiment. FIG. 17 is a schematic perspective view of the main part of the case of the drying apparatus shown in FIG. FIG. 17 shows only the case 501 of the portion provided with the reverse attachment preventing member 5045 in a simplified manner for the sake of understanding.

  That is, as shown in FIG. 16, the drying device 1600 of another example 5 is particularly different from the above in that a convex rib having a rectangular cross section is installed on the top of the side wall 5011 c of the case 501 as the reverse installation preventing member 5045 Unlike the drying device 1100 of Example 3, the drying device 1400 of another example 4 is different.

  In addition, although the reverse configuration preventing member of various shapes and arrangements has been described using FIGS. 12 to 17, the above reverse configuration preventing member is merely an example. For example, as long as the plate-like member 5041 of the waterproof shielding plate 504 can be prevented from being reversely incorporated according to the actual situation, another specific shape or installation method of the reverse attachment preventing member may be used. Needless to say.

  As described above, according to the present embodiment, the air passage behind the waterproof shield is in the closed state while the drying device is stopped. Thereby, even when water infiltrates from a blower outlet, it can prevent it from invading back by a waterproof shielding board. In addition, it is possible to prevent the occurrence of an abnormality such as a short circuit due to water immersion by the heater and the blower installed at the back by the waterproof shielding plate.

  Moreover, the space which accommodates a waterproof shielding board in a ventilation path can be made small by comprising a waterproof shielding board by the plate-shaped member of at least 2 sheet. As a result, the overall length of the drying device can be shortened to achieve miniaturization. In addition, since the waterproof shielding plate can be configured by a relatively light plate member, the waterproof shielding plate can be easily opened with a small wind force. As a result, the energy consumption of the drying device can be reduced.
