Further, in the illustrated specific example, each of the water discharge portions 21 to 23 protrudes separately from the back surface portion 2, but as shown in FIG. 5, each water discharge portion (FIG. The first and second water dischargers 21 and 22 may be incorporated in one unit body 14.

Next, the operation of the shower bath device according to the present embodiment will be described.
FIG. 6 is a perspective view schematically illustrating a state of water discharge in the shower flow from each of the water discharge units 21 to 23 with respect to the seated person 200.

  As shown in FIGS. 2 and 6, from the first water discharger 21, a shower flow that drops in the vicinity of the front edge of the jet seat 4 in a substantially horizontal direction is discharged. That is, a shower flow is discharged from the first water discharger 21 over the shoulder of the seated person 200 to the front of the seated person 200 by a trajectory that draws an arc due to its own weight, and the lower limbs of the seated person 200, particularly around the thigh A shower flow falls in the vicinity. Then, this shower flow flows on the surface of the lower limb from the knee of the seated person 200 toward the foot. By setting in such a water discharge direction, even if the first water discharge portion 21 is provided in the vicinity of the head far from the lower limb of the seat occupant 200, the seat occupant 200 By discharging water over the shoulders of the 200, the discharged water flow can surely reach the lower limbs without being obstructed by the seated person 200, so that the lower limbs can be warmed from the knees.

  The shower flow from the first water discharger 21 is not limited to the case where the shower flow passes just above the shoulder of the seated person 200 but also the case where the shower flows near the shoulder (shoulder tip) of the seated person 200. It is. However, if the shower flow passes just above the shoulder of the seated person 200, the shower flow reaches the lower limb at the shortest distance from the first water discharge portion 21 provided on the back side of the seated person 200. Can do. That is, the temperature drop during the flight until the shower flow discharged from the first water discharger 21 reaches the lower limb can be suppressed, and the lower limb can be warmed with the shower flow at a desired temperature.

  From the second water discharger 22, a shower flow is discharged toward the shoulder near the base of the neck of the seated person 200. Part of the shower flow that hits the shoulder flows on the front surface of the body centering on the side from the chest to the torso of the seated person 200, and the other part of the shower flow wraps around the back. In this way, both the front side and back of the seated person 200 can be warmed. Moreover, the massage effect by a shower style can also be made to act on a shoulder part.

  The shower flow is discharged from the second water discharge portion 22 toward the shoulder near the base of the neck of the seated person 200, and the shower flow is caused to flow to the front and back of the upper body of the seated person 200. Even if it is only a pair of 2nd water discharging parts 22 provided in, the whole upper body of the seated person 200 can be warmed efficiently. That is, a high thermal effect can be obtained while reducing the cost by minimizing the water discharge portion.

  The hot water that wraps around the back side of the seated person 200 continuously flows toward the seat part 4 along the back or backrest part 5 of the seated person 200. That is, since the hot water discharged from the second water discharge portion 22 flows into the backrest portion 5 one after another, there is no temperature boundary layer between the back and the backrest portion 5 of the seated person 200, and the heat of the hot water is generated by the seated person 200. It becomes easy to be transmitted to the back. Since not only the front side of the body but also the back side can be warmed at the same time, the thermal effect can be enhanced even with a small flow rate, and water saving and energy saving can be achieved by saving the amount of hot water used.

  Moreover, since the backrest part 5 is partitioned off by the wall part 7 formed in the both ends of the 1st direction x (width direction), and is formed in the concave shape connected to the seat part 4, it flowed into the backrest part 5. Hot water can be reliably guided to the seat 4 without waste by suppressing scattering and outflow of hot water. In other words, even if the flow rate is small, the thermal effect is not impaired, and water saving and energy saving are achieved by saving the amount of hot water used.

  From the 3rd water discharging part 23, a shower flow is discharged toward the shoulder part (shoulder top part) of the seated person 200. The shower flow that hits the shoulder ridge flows to a portion around the center of the arm and warms that portion. You can also apply a shower from your shoulder to your chest.

  The seat portion 4 is partitioned by walls 6 formed at both ends in the first direction x (width direction), and is formed as a recess connected to the backrest portion 5, so that lateral leakage of hot water is suppressed, Hot water from the water dischargers 21 to 23 can be used efficiently without waste. That is, it is possible to save water and save energy by saving the amount of hot water used.

  Since the hot water flows into the seat part 4 one after another along the body surface or the backrest part 5 of the seated person 200, a temperature boundary layer does not develop between the seated person 200 and the seat part 4, and the heat of the hot water is seated. It becomes easy to be transmitted to the buttocks and thighs of the person 200, and the thermal effect can be enhanced.

  Furthermore, the hot water accumulated in the seat part 4 flows out forward (direction y in FIG. 1) and flows from the leg part of the seated person 200 to the foot. As a result, the feet can be warmed up without wasting hot water. In particular, if the recess 4A as illustrated in FIG. 3B is provided, the hot water accumulated in the seat 4 is easy to flow toward the leg of the seated person 200, which is efficient.

  In addition, by immersing the shower flow from the first to third water dischargers 21 to 23 throughout the body while immersing in the hot water accumulated in the seat 4, the sensation of bathing (the feeling of bathing) ) And a high thermal effect can be obtained while being a shower bath. And compared with the case where it is immersed in a bathtub, water pressure is not applied to a body and there are few burdens to a body. Since there is no need to move in and out of the bathtub and it can be used while sitting, a high thermal effect can be easily obtained even for an elderly person or a user who has a physical movement disorder. Also, instead of taking a shower for each part of the body, the whole body can be showered at the same time, so the body can be warmed by taking a shower while saving water in a short time.

  Further, since the water discharged from each of the water discharge units 21 to 23 is not a spray but a shower flow made of a continuous water flow, the surrounding space becomes a high-temperature and high-humidity atmosphere as in the case of spraying mist (spray). Therefore, you can prevent the upside-down. Furthermore, since the temperature drop of the discharged water due to the heat of vaporization is small, it is not necessary to set the shower temperature higher than necessary, which is economical.

  In addition, the shower flow discharged from the 1st-3rd water discharging parts 21-23 in the shower-bath apparatus of this embodiment is discharged from the several shower hole provided in each water discharging part. The hole diameter is desirably within a range of 0.2 mm to 4 mm, for example, and within this range, the hole can be efficiently heated over a wide range with a small flow rate.

  Moreover, compared with patent document 1 with which the arm which provided the several water discharging part protrudes ahead of a seated person, in this embodiment, by providing each water discharging part 21-23 in the bathroom wall surface behind the seated person 200 integrally. In the limited bathroom space, the installation space can be saved, and the compact and clean structure eliminates the annoyance in the bathroom and does not impair the design. Further, since there is no arm protruding forward, for example, the operation of transferring the user from the wheelchair to the seat 4 of the shower bath device can be performed safely and easily, and it is easy to use.

  Further, by appropriately setting the water discharge direction of the shower flow from each of the water discharge units 21 to 23 as described above, even if a large number of water discharge units are not provided in front of the seat occupant 200, the minimum is provided behind the seat occupant. A shower bath that efficiently warms the entire body of the seated person 200 can be realized even with a small amount of hot water. Costs can be reduced by minimizing the water discharge part. Moreover, it becomes water saving and energy saving by suppressing the amount of hot water required.

From the 2nd water discharging part 22, the shower flow which falls in the slanting downward direction with respect to a horizontal surface and falls to the front-edge vicinity of the seat part 4 is discharged. That is, the shower flow that falls directly from the second water discharge portion 22 provided on the back surface portion 2 to the vicinity of the front edge of the seat portion 4 is discharged without passing through the arm protruding into the bathroom space as in Patent Document 1 above. The In the state where the seated person is seated on the seat portion 4, since the water flow is applied to the seated person and does not fall directly near the front edge of the seat portion 4, “Falling near the front edge of the part 4” includes “falling near the lower leg of the seated person sitting on the seat part 4”. From another point of view, the shower water flows from the second water discharger 22 obliquely downward over the shoulder of the seated person 200, and in the vicinity of the leg of the seated person 200, particularly around the thigh. Falls. Then, this shower flow flows on the surface of the lower limb from the knee of the seated person 200 toward the foot.

  Even if the second water discharger 22 is provided in the vicinity of the head behind the seated person 200 and far from the lower limb of the seated person 200, by discharging water over the shoulder of the seated person 200, It is possible to reliably warm the lower limbs from the knees by causing the water discharge to reach the lower limbs without being blocked by the seated person 200.

  From the first water discharger 21, a shower flow is discharged toward the shoulder near the base of the neck of the seated person 200. A part of the shower flow that hits the shoulder flows on the front and side of the body from the chest to the torso of the seated person 200, and another part of the shower flow that hits the shoulder wraps around the back. . In this way, both the front side and back of the seated person 200 can be warmed. Moreover, the massage effect by a shower style can also be made to act on a shoulder part.

  The shower flow is discharged from the first water discharge portion 21 toward the shoulder near the base of the neck of the seated person 200, and the shower flow is caused to flow to the front and back of the upper body of the seated person 200, thereby Even if it is only a pair of 1st water discharging part 21 provided in 1st, the whole upper body of the seated person 200 can be warmed efficiently. That is, a high thermal effect can be obtained while reducing the cost by minimizing the water discharge portion.

  The hot water that wraps around the back side of the seated person 200 continuously flows toward the seat part 4 along the back or backrest part 5 of the seated person 200. That is, since the hot water discharged from the first water discharge portion 21 flows into the backrest portion 5 one after another, there is no temperature boundary layer between the back and the backrest portion 5 of the seated person 200, and the heat of the hot water is generated by the seated person 200. It becomes easy to be transmitted to the back. Since not only the front side of the body but also the back side can be warmed at the same time, the thermal effect can be enhanced even with a small flow rate, and water saving and energy saving can be achieved by saving the amount of hot water used.

  Moreover, since the backrest part 5 is formed in the concave shape connected to the seat part 4, scattering and outflow of the hot water which flowed into the backrest part 5 can be suppressed, and hot water can be reliably guided to the seat part 4 without waste. it can. In other words, even if the flow rate is small, the thermal effect is not impaired, and water saving and energy saving are achieved by saving the amount of hot water used.

  According to the present embodiment, by receiving the shower flow from the water discharge portions 21 and 22 over the entire body, it is possible to obtain a feeling of bathing in the hot water as in the early stage of bathing in the bathtub (a feeling of bathing). High thermal effect can be obtained. And compared with the case where it is immersed in a bathtub, water pressure is not applied to a body and there are few burdens to a body. Since there is no need to move in and out of the bathtub and it can be used while sitting, a high thermal effect can be easily obtained even for an elderly person or a user who has a physical movement disorder. Also, instead of taking a shower for each part of the body, the whole body can be showered at the same time, so the body can be warmed by taking a shower while saving water in a short time.

  In addition, since water is discharged from each water discharge section 21 and 22 is not a spray but a shower flow consisting of a continuous water flow, if the surrounding space becomes a high-temperature and high-humidity atmosphere as in the case of spraying mist (spray). Therefore, you can prevent the upside-down. Furthermore, since the temperature drop of the discharged water due to the heat of vaporization is small, it is not necessary to set the shower temperature higher than necessary, which is economical.

  In addition, the shower flow discharged from each water discharge part 21 and 22 in the shower-bath apparatus of this embodiment is discharged from the several shower hole drilled in each water discharge part 21 and 22. FIG. The hole diameter is desirably within a range of 0.2 mm to 4 mm, for example, and within this range, the hole can be efficiently heated over a wide range with a small flow rate. The “shower flow” includes a case where water is discharged in the form of a line at the moment when water is discharged from the water discharge portion, and a case where water is discharged in the form of a droplet (mist flow).

  In addition, compared with Patent Document 1 in which an arm provided with a plurality of water discharge portions protrudes forward of the seated person, in the present embodiment, the water discharge portions 21 and 22 are provided integrally on the bathroom wall behind the seated person 200. In the limited bathroom space, the installation space can be saved, and the compact and clean structure eliminates the annoyance in the bathroom and does not impair the design. Further, since there is no arm protruding forward, for example, the operation of transferring the user from the wheelchair to the seat 4 of the shower bath device can be performed safely and easily, and it is easy to use. Moreover, since there is no arm, it does not interfere with the operation of washing the body or hair while sitting on the seat 4 or in the vicinity of the shower bath device.

  In addition, by appropriately setting the water discharge direction of the shower flow from each water discharge unit 21 and 22 as described above, even if a large number of water discharge units are not provided in front of the seat occupant 200, the minimum is provided behind the seat occupant. A shower bath that efficiently warms the entire body of the seated person 200 can be realized even with a small amount of hot water. Costs can be reduced by minimizing the water discharge part. Moreover, it becomes water saving and energy saving by suppressing the amount of hot water required.

  As shown in FIG. 43, these wing parts 2 </ b> W are provided with a first water discharge part 21, a second water discharge part 22, and a third water discharge part 23. From each of these water discharge parts 21, 22, and 23, one or more shower-like water discharge is enabled. On the other hand, the seat portion 4 has an inclined surface inclined downward from the front edge toward the backrest portion 5. The seat part 4 formed in this way is capable of storing hot water in cooperation with the wall part 6 and the backrest part 5 provided at both side ends thereof. In addition, an opening 31 is provided at the lowest vertical portion of the seat 4. On the other hand, a pair of lower limb back spouting portions 33 are provided on the front surface of the base portion 3. These lower limb back spouting units 33 communicate with the opening 31. That is, the hot water discharged from the water discharge portions 21, 22, and 23 and dropped onto the seat portion 4 is guided to the lower limb back water discharge portion 33 from the opening portion 31, and sits on the seat portion 4 as shown by the arrow D in FIG. Water is discharged toward the back of the lower limb of the seated person. In this way, the shower flow can be applied evenly to the back side of the lower limbs of the seated person to give a warming or massage effect. In addition, the hot water which fell to the seat part 4 may not be discharged from the lower limb back spout unit 33, but the hot water supplied from the hot water supply source may be guided to the lower limb back spout unit 33 to discharge water.

  The hot water discharged from the first water discharger 21 falls in the vicinity of the lower limb centered on the thigh of the seated person sitting on the seat 4 as represented by an arrow A in FIG. Further, the hot water discharged from the second water discharger 22 falls within the range from the neck to the shoulder of the seated person sitting on the seat 4 as represented by the arrow B in FIG. Further, the hot water discharged from the third water discharger 23, as represented by the arrow C in FIG. 45, wraps the seated person sitting on the seat 4 from both sides to the upper limbs. Cover the range including before and after. You can also apply a shower from your shoulder to your chest. In addition, a part of the hot water discharged and a portion of the hot water that has flowed down through the body of the seated person is stored in the seat 4. That is, the lower side of the buttocks and thighs of the seated person sitting on the seat 4 is warmed by the hot water stored in the seat 4. In this way, almost the entire body below the neck of the seated person 200 can be warmed evenly.

  Since the shower bath apparatus of this embodiment has the form of an independent chair, it can be installed easily without constructing a shower booth or a bathroom. And with a relaxed sitting posture like a sofa, you can enjoy the benefits of a comfortable full-body shower bath. Further, if a vibration generator is provided on the back side of the seat part 4 and the backrest part 5 of the shower bath device, it is possible to give a vibration massage effect to the seated person. In this way, a higher effect can be obtained by superimposing the relaxation effect and massage effect by the shower bath and the massage effect by vibration.

[Example]
Next, examples implemented by the present inventor will be described.
The inventor of the present invention uses a shower bath by the shower bath device of the first embodiment, bathing by a bathtub in which hot water is stored, a shower bath by a conventional hand shower, and a shower bath by a shower bath device disclosed in Patent Document 1. An experiment was carried out to measure the warming effect.

  Here, in the shower-bath apparatus of 1st Embodiment, the temperature of the hot water supplied to the water discharging part 21,22,23 was 43 degreeC, and the total amount of the hot water discharged from these water discharging parts was 10 liters per minute. The case (case A) was tested. In addition, bathing in a bathtub in which hot water was stored (Case C) was performed by storing 230 liters of 40 ° C. hot water in the bathtub. On the other hand, in the case of a conventional hand shower (Case D), the temperature of hot water supplied to the shower head was 43 ° C., and the flow rate was 8 liters per minute. On the other hand, in the shower bath apparatus (case E) disclosed in Patent Document 1, 10 liters of hot water was ejected in a mist form per minute to perform the shower bath. In any of these cases, a change in the temperature of the body surface of the subject was measured with a radiation thermometer immediately before bathing and after bathing for 5 minutes.

FIG. 46 is a graph showing changes in the temperature of the body surface of the whole body of the subject. Here, the vertical axis represents the increase from the temperature immediately before bathing. Here, the average temperature of the body surface of the whole body below the neck was defined as the temperature of the whole body.
Compared with just before bathing, the temperature rise immediately after bathing for 5 minutes is 3.5 ° C. in the bathtub (C), 3.2 ° C. in the shower bath device of this embodiment (A), and the shower bath device of Patent Document 1 It was 2.2 degreeC in (E), and 1.8 degreeC in the conventional shower (D). That is, it is the highest when bathing in the bathtub (C), and in the present embodiment (A), it can be seen that a temperature close to that is obtained. On the other hand, it can be seen that the temperature rise is small in the case of the shower bath device (E) disclosed in Patent Document 1 and the case of the conventional hand shower (D) as compared with these.

  Moreover, when 5 minutes passed after bathing, it was 2.9 degreeC (C), 2.5 degreeC (A), 2.2 degreeC (E), and 1.7 degreeC (D), respectively. And when 10 minutes passed after bathing, it was 2.4 degreeC (C), 2.2 degreeC (A), 2.0 degreeC (E), and 1.5 degreeC (D), respectively. That is, when 10 minutes elapse after bathing, the shower bath by the shower bath device of the present embodiment has the same temperature as bathing in the bathtub. This is considered to be because, in the case of the shower bath device of the present embodiment, not only the thermal effect by hot water, but also the massage effect and blood circulation promoting effect by taking a shower all over the body in a relaxed posture can be obtained. .

FIG. 47 is a graph showing changes in the temperature of the body surface of the subject's shoulder. Again, the vertical axis represents the increase from the temperature just before bathing.
Compared with just before bathing, the shoulder temperature rise immediately after bathing for 5 minutes is 2.9 ° C. in the shower bath device (A) of this embodiment, and 1. The temperature was 6 ° C, 1.1 ° C in the bathtub (C), and 0.8 ° C in the conventional shower (D). That is, the case of the shower bath device of the present embodiment is extremely high, and the shower bath device (E), the bathtub (C), and the conventional hand shower (D) disclosed in Patent Document 1 are all relatively. It turns out that it is low. In the case of the shower bath device of the present embodiment, the shower flow from the second water discharge unit 22 and the third water discharge unit 23 (see FIG. 1) is evenly applied to the shoulders of the seated person and can be sufficiently warmed. It is thought that it is from. In contrast, for example, in the case of the shower bath device disclosed in Patent Document 1 (E), it is considered that the mist sprayed from the arm cannot sufficiently warm up to the shoulder of the seated person. On the other hand, in the case of the bathtub (A), it is difficult for the bather to maintain the state where the shoulder is completely submerged in the hot water for a long time, and the user has to take a bath with the shoulder taken out of the hot water. For this reason, even if the body warms up, it is difficult for the shoulders to warm up. In the case of the conventional hand shower (D), the shower flow from the shower head does not necessarily hit the bather's body, and it is not easy to efficiently warm the bather's whole body without unevenness.

  When 5 minutes passed after bathing, they were 2.3 ° C. (A), 1.8 ° C. (E), 1.4 ° C. (D), and 1.1 ° C. (C), respectively. And when 10 minutes passed after bathing, it was 1.9 degreeC (A), 1.8 degreeC (E), 1.5 degreeC (D), and 1.0 degreeC (C), respectively. That is, even when 10 minutes have passed since the bathing, the highest temperature was obtained in the shower bath device (A) of the present embodiment. In addition, in the case of the conventional hand shower (D) and the shower bath apparatus (E) disclosed in Patent Document 1, the temperature gradually increases after 5 minutes and 10 minutes from immediately after bathing. This is thought to be because, in these methods, the warmth of the shoulders is particularly low compared to other parts of the body, and heat from the other parts of the body is transferred to the shoulders by the blood flow after bathing. It is done.

FIG. 48 is a graph showing changes in the temperature of the body surface of the lower limb of the subject. Again, the vertical axis represents the increase from the temperature just before bathing.
Compared with just before bathing, the temperature rise of the lower limbs after bathing for 5 minutes was the highest at 3.5 ° C. in the case of the bathtub (C), but in the shower bath device (A) of this embodiment, 3. It was 2 degreeC and the temperature rise substantially equivalent to a bathtub (C) was obtained. That is, according to the present embodiment, the water discharged from the first water discharger 21 (see FIG. 1) directly onto the lower limbs of the seated person or the water discharged from the second water discharger 22 and the third water discharger 23 is seated. It can be seen that the lower limb of the seated person can be sufficiently warmed by the hot water flowing from the front edge of the seat portion 4 on the body.

  On the other hand, in the case of the conventional hand shower (D) and the shower bath device (E) of Patent Document 1, the temperatures immediately after bathing are as low as 2.3 ° C. and 2.1 ° C., respectively. In the case of a conventional hand shower (C), it is not easy to apply hot water evenly to the lower limbs of the bather. Further, in the case of the shower bath device disclosed in Patent Document 1, it is not easy to wrap the entire lower limb of the seated person with the mist ejected from the arm, and the temperature of the mist ejected from the arm is rapidly decreased. Therefore, it is considered difficult to warm the entire lower limbs of the seated person.

  As described above, according to the present example, it was found that a high warming effect can be obtained by the shower bath device of the present embodiment for the whole body, the shoulders, and the lower limbs. For example, for the whole body and lower limbs, the shower bath device of the present embodiment can obtain a warming effect equivalent to bathing in a bathtub. Here, in the case of a bathtub, for example, about 230 liters of hot water is required, but according to the present embodiment, a very small amount of hot water of 50 liters (case A) is required after 5 minutes of bathing. That is, a high water-saving effect is also obtained. Even if four people take a bath continuously, the same warming effect can be obtained with less hot water than the bathtub (case).

  Moreover, when it sees about a shoulder, the warming effect higher than a bathtub is acquired. Furthermore, according to this embodiment, the massage effect by dropping water discharge on a seated person's body is also acquired. Thereby, for example, the effect of relieving shoulder “stiffness” and pain can be obtained.

The first to nineteenth embodiments and examples of the present invention have been described above.
In each embodiment mentioned above, the height from the seat part 4 of each water discharging part is 400-1400 (mm), for example, Preferably it is 500-1000 (mm) in order to acquire the above-mentioned effect more reliably. More preferably, it is 650-900 (mm).
Moreover, the height from the floor surface of the seat part 4 is 250-800 (mm), for example, Preferably it is 300-500 (mm), and more preferably 350-500 in order to acquire the above-mentioned effect more reliably. 450 (mm).
Moreover, when the use in a shower booth is assumed, the height from the floor surface to the seat part 4 should just be the range of the height which can be hung about 250-800 (mm).

  In addition, the distance (width) between the outermost third water discharger that forms a pair across the center of the seat 4 is, for example, 340 to 1200 (mm), which is preferable in order to obtain the above-described effect more reliably. Is 500 to 800 (mm), more preferably 550 to 650 (mm).

  Moreover, in each specific example mentioned above, the average particle diameter of the hot water discharged from the 1st water discharging part 21 or the 2nd water discharging part 52 is the 1st water discharging part 51, the 2nd water discharging part 22, 3rd. The average particle diameter of the hot water discharged from the water discharge portions 23 and 53 can be made larger. Specifically, for example, the average particle diameter of hot water discharged from the first water discharger 21 or the second water discharger 52 is set to a range of 1400 to 3000 micrometers, and the first water discharger 51 and the second water discharger. The average particle diameter of the hot water discharged from the part 22 and the third water discharge parts 23 and 53 can be in the range of 500 to 1400 micrometers. If it does in this way, it will be discharged from the 1st water discharging part 21 and 52, the fall of the temperature after the water discharge of the shower style which falls to a seated person's lower limb part will be suppressed, and warm hot water shall be applied to a seated person's lower leg part. Can do. At the same time, water is discharged from the first water discharge portions 21 and 52, and stimulation by the shower flow that falls on the lower limbs of the seated person can be appropriately given to obtain a massage effect. The particle size of the hot water can be controlled by adjusting the size and shape of the water discharge holes.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to the specific examples described above.
For example, the above-described embodiments may be combined as appropriate as technically possible, and these are also included in the scope of the present invention. Further, a flow rate adjusting means or a pressure adjusting means capable of adjusting the water discharge flow rate or the water discharge pressure may be provided so that the water discharge always reaches the lower limbs stably regardless of the hot water supply pressure or its fluctuation.
Further, even if those skilled in the art appropriately change or add the structure, shape, function, arrangement relationship, material, etc. of each element in each specific example, they are included in the scope of the present invention as long as the gist of the present invention is included.
