Description

Technical Field

[0001] The present invention relates to a water spray device (such as a shower device). Background Art

[0002] In recent years, multifunctional shower devices that are not intended only for cleaning the body have been proposed.

[0003] The human body perceives temperature differently depending on its body part. Therefore, even when showering with water of the same temperature, people may experience temperature differences. Therefore, a shower device is known that actively varies the particle size of hot water to create a temperature distribution in the sprayed water, providing a uniform perceived temperature and a comfortable shower mist (Patent Document 1).

[0004] Specifically, a method is proposed in which a difference in particle size is actively created between the shower mist sprayed toward the user's chest and the shower mist sprayed toward the user's abdomen to actively generate uneven temperature of the sprayed water, thereby eliminating uneven temperature felt by the user.

[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2009-189606

[0006] The present inventor has embarked on the development of a shower device suitable for daytime rest. During daytime rest, it is desired to provide comfortable fatigue recovery and comfortable awakening.

[0007] In order to recover from fatigue, it is necessary to provide a warming effect that promotes blood circulation. In addition, in order to provide a sense of alertness, it is necessary to provide a warming effect such as stimulating the sympathetic nerves and tactile stimulation.

[0008] On the other hand, when the whole body is bathed in a shower of hot water of uniform temperature, sweating is promoted in parts that are prone to sweating, which is not suitable for daytime rest.

[0009] In Patent Document 1, temperature unevenness is formed between the water sprayed to the chest and the water sprayed to the abdomen, but the inventors have repeatedly conducted diligent research and experiments on which part of the user's body should be sprayed with what temperature of water, based on the perspective of daytime rest.

[0010] Furthermore, it was found that setting the temperature of the hot water reaching (impacting) the area corresponding to the user's head (particularly the back and front of the head) to a lower temperature and setting the temperature of the hot water reaching (impacting) the other areas of the user to a higher temperature is suitable for daytime rest. Summary of the Invention

[0011] The present invention is based on the above findings and is intended to provide a shower device suitable for daytime relaxation by setting the temperature of hot water reaching (impacting) the area corresponding to the user's head (particularly the back and front of the head) to a lower temperature and setting the temperature of hot water reaching (impacting) the other areas of the user to a higher temperature.

[0012] Furthermore, in Patent Document 1, the temperature of the shower mist sprayed toward the user's abdomen (a part where sweating is low) is set low, and therefore it is ineffective in warming the body while suppressing sweating.

[0013] Furthermore, in Patent Document 1, the flow path from the hot water supply source to the water spray section with larger particle sizes is shorter than the flow path from the hot water supply source to the water spray section with smaller particle sizes. Therefore, if the user mistakenly increases the temperature setting, hot water can easily be sprayed toward the user, posing a risk of scalding. (When spraying water of different particle sizes through the same flow path, the larger particle size sprays less frequently, resulting in a higher risk of scalding.)

[0014] Another group of the present invention is original and is based on the above-mentioned knowledge. Another group of the present invention aims to provide a shower device which reduces the risk of burns to the user and is suitable for daytime rest.

[0015] The present invention is a water spray device, characterized in that it comprises: a first water spray portion, which sprays hot water toward a first water spray range corresponding to the head of a user in a specified position; and a second water spray portion, which sprays hot water toward a second water spray range below the first water spray range for the user, wherein the temperature of the hot water sprayed from the first water spray portion when reaching the user is lower than the temperature of the hot water sprayed from the second water spray portion when reaching the user.

[0016] According to the present invention, the temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is lower than the temperature of the hot water reaching (impacting) the second water spray range below the first water spray range, thereby providing a shower device suitable for daytime relaxation.

[0017] The temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is relatively low, so the lower temperature hot water reaches the head (which is full of thick arteries) and the back just below the head (which is generally prone to sweating), thereby suppressing sweating.

[0018] On the other hand, by setting the temperature of the hot water reaching (impacting) the second water spray area, which is lower than the first water spray area, to be relatively high, the user can also enjoy a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0019] The first water spray range can be set and changed (adjustable) in accordance with the height of the user, for example.

[0020] Furthermore, it is preferable that the first water spray part and the second water spray part are arranged to face each other with the predetermined position interposed therebetween.

[0021] As a result, the second water spray range becomes a part of the body that is relatively insensitive to heat (especially the front side of the body), so that the warmth of the body can be felt more reliably.

[0022] Furthermore, it is preferable that the first water spraying part and the second water spraying part spray water so that the hot water spreads.

[0023] Thus, the first water spray part and the second water spray part spray water in a manner that the hot water spreads, and therefore, even if the water spray port is not designed to be large, the hot water can be applied to a wide area of ​​the human body.

[0024] Furthermore, it is preferable that an angle formed by a central direction of water spraying formed by the first water spraying part with respect to a vertical direction is larger than an angle formed by a central direction of water spraying formed by the second water spraying part with respect to the vertical direction.

[0025] According to this method, the hot water from the first water spray section is easily sprayed locally toward the first water spray range corresponding to the user's head. On the other hand, the hot water from the second water spray section is sprayed toward the second water spray range below the first water spray range, and is more likely to be sprayed more widely than the water from the first water spray section. Therefore, the hot water reaches a wider range of the user's body parts, and the warmth of the body can be felt more reliably.

[0026] Furthermore, it is preferable that the second water spray portion is configured to spray hot water toward the front, left, and right sides of the user.

[0027] According to this aspect, the hot water reaches the front, left, and right sides of the user, so the user can feel the warmth of the body more reliably.

[0028] Furthermore, it is preferable to further include an operating unit for performing an operation input to the first water spray unit and / or the second water spray unit, and the first water spray unit and the operating unit are arranged to face each other with the predetermined position interposed therebetween.

[0029] According to this mode, when the hot water from the first water spray portion is spraying water in the first water spray range corresponding to the user's head, the user can easily observe the operating portion or operate it. In addition, it is also possible to prevent the lower temperature hot water from rushing onto the user's face.

[0030] In addition, it is preferred to further include: a mixing valve, which is connected to the cold water supply pipe and the hot water supply pipe in order to generate the hot water; a first flow path portion, which connects the mixing valve and the first water spray portion; and a second flow path portion, which connects the mixing valve and the second water spray portion, and the particle size of the hot water sprayed from the first water spray portion through the first flow path portion is smaller than the particle size of the hot water sprayed from the second water spray portion through the second flow path portion.

[0031] Small hot water particle sizes facilitate a drop in temperature after spraying. By utilizing this principle, even with a relatively simple structure using a common mixing valve, it is possible to easily achieve a state where the temperature of hot water reaching (impacting) the first spray area corresponding to the user's head is lower than the temperature of hot water reaching (impacting) the second spray area below the first spray area.

[0032] In addition, the first mode of another group of the present invention is a water spray device, characterized in that it comprises: a hot and cold water mixing section, which mixes high-temperature hot water and cold water to generate hot water of a desired temperature; a first water spray section, which sprays hot water toward a user at a specified position; a second water spray section, which is independently provided with the first water spray section, and sprays hot water toward the user at the specified position; a first flow path section, which reaches the first water spray section from the hot and cold water mixing section; and a second flow path section, which reaches the second water spray section from the hot and cold water mixing section, the first flow path section and the second flow path section branch off via a branch section provided on the downstream side of the hot and cold water mixing section, the particle size of the hot water sprayed from the second water spray section via the second flow path section is larger than the particle size of the hot water sprayed from the first water spray section via the first flow path section, and the length of the second flow path section is longer than the length of the first flow path section.

[0033] According to the first embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion with a large particle size is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion with a small particle size. Therefore, even if a high temperature setting is erroneously performed, the temperature of the water sprayed with large particle sizes from the second water spray portion can be expected to decrease, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0034] The second mode of another group of the present invention is a water spray device, characterized in that it comprises: a hot and cold water mixing section, which mixes high-temperature hot water and cold water to generate hot water of a desired temperature; a first water spray section, which sprays hot water toward a user at a specified position; a second water spray section, which is independently provided with the first water spray section, and sprays hot water toward the user at the specified position; a first flow path section, which reaches the first water spray section from the hot and cold water mixing section; and a second flow path section, which reaches the second water spray section from the hot and cold water mixing section, the first flow path section and the second flow path section branch off via a branch section provided on the downstream side of the hot and cold water mixing section, a flow rate of the hot water sprayed from the second water spray section via the second flow path section is smaller than a flow rate of the hot water sprayed from the first water spray section via the first flow path section, and a length of the second flow path section is longer than a length of the first flow path section.

[0035] According to the second embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion with a low flow rate is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion with a high flow rate. Therefore, even if a high temperature setting is erroneously performed, the temperature of the water sprayed with a low flow rate from the second water spray portion can be expected to decrease, reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0036] The third mode of another group of the present invention is a water spray device, characterized in that it comprises: a hot and cold water mixing section, which mixes high-temperature hot water and cold water to generate hot water of a desired temperature; a first water spray section, which sprays hot water toward a user at a specified position; a second water spray section, which is independently arranged from the first water spray section, and sprays hot water toward the user at the specified position; a first flow path section, which reaches the first water spray section from the hot and cold water mixing section; a second flow path section, which reaches the second water spray section from the hot and cold water mixing section; and a temperature reducing device, which is arranged to actively reduce the temperature of the hot water sprayed from the first water spray section via the first flow path section, the first flow path section and the second flow path section branching off via a branch section arranged on the downstream side of the hot and cold water mixing section, and the length of the second flow path section is longer than the length of the first flow path section.

[0037] According to the third embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion. Therefore, even in the case of a high temperature setting by mistake, the temperature of the water sprayed from the second water spray portion without passing through the temperature reduction device can be expected to be reduced, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0038] In each of the above aspects, the first water spray section and the second water spray section are preferably arranged relative to each other with the specified position sandwiched therebetween, and the water spray range formed by the second water spray section is lower than the water spray range formed by the first water spray section.

[0039] In each of the above methods, the water sprayed by the second water spray section tends to be high temperature, but by setting the water spray range formed by the second water spray section to be further downward, it is possible to prevent the high-temperature hot water from directly reaching (impacting) the user's face regardless of the direction in which the user uses the water spray device.

[0040] Furthermore, even when the hot water reaching (impacting) the spray area of ​​the second water spray section, which is located below the spray area of ​​the first water spray section, is at a relatively high temperature, the user can still enjoy a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0041] The water spray range formed by the first water spray unit is preferably a range corresponding to the user's head in a predetermined position, for example, a height range of 120 cm to 130 cm (the setting can be changed (adjustable) to match the user's height). In this case, if the first water spray unit and the second water spray unit are arranged to face each other with the predetermined position sandwiched between them, the water spray range formed by the second water spray unit becomes a part of the body that is less sensitive to heat (particularly the front of the body). Therefore, the user can more reliably feel the warmth of the body.

[0042] In addition, the first water spraying part preferably sprays the hot water in the form of water mist (spraying water in small particle sizes of 1 mm or less).

[0043] According to this aspect, on the first water spraying portion side where the distance from the hot and cold water mixing portion (hot water supply source) to the water spraying portion is short, even if high-temperature water is sprayed, the heat can be released into the air more reliably and the water can reach the user.

[0044] When spraying water in the form of water mist, if the temperature of the hot water near the water outlet is, for example, 39.8° C., the temperature of the hot water when it reaches (impacts) the user's body is, for example, approximately 28.7° C. (relatively low).

[0045] Furthermore, it is preferred that the first water spray section and the second water spray section are arranged at approximately the same height position, and the angle formed by the water spray center direction formed by the first water spray section relative to the vertical direction is larger than the angle formed by the water spray center direction formed by the second water spray section relative to the vertical direction.

[0046] According to this method, the water (hot water) sprayed from the second water spray section is directed downward compared to the spray range formed by the first water spray section, and is sprayed more widely than the water sprayed from the first water spray section. Therefore, the hot water reaches a wider area of ​​the user's body, and the user can feel the warmth more reliably. In addition, even if a high temperature setting is mistakenly set, the water (hot water) sprayed from the second water spray section can be accelerated to cool in the air.

[0047] A plurality of the second water spray parts may be provided. In this case, one or more second branch parts may be provided between the plurality of second water spray parts and the branch part.

[0048] In this case, the second flow path portion branches through the second branch portion, so it can be expected that the heat conduction (heat dissipation) effect obtained by the above-mentioned second flow path portion will be further improved, and the temperature will be reduced by the (low-temperature) residual hot water in the above-mentioned second flow path portion.

[0049] Effects of the Invention

[0050] According to one set of the present invention, the temperature of the hot water that reaches (impacts) the first water spray range corresponding to the user's head is lower than the temperature of the hot water that reaches (impacts) the second water spray range below the first water spray range, thereby providing a shower device suitable for daytime rest. In particular, the relatively low temperature of the hot water that reaches (impacts) the first water spray range corresponding to the user's head allows the lower-temperature hot water to reach the head (which is covered with thick arteries) and the back directly below the head (which is generally prone to sweating), thereby suppressing sweating. On the other hand, by setting the temperature of the hot water that reaches (impacts) the second water spray range below the first water spray range to be relatively high, the user can also obtain a comfortable warming effect. That is, it is possible to achieve both sweat suppression and body warming, and provide a shower device suitable for daytime rest.

[0051] According to the first embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion with a large particle size is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion with a small particle size. Therefore, even if a high temperature setting is erroneously performed, the temperature of the water sprayed with large particle sizes from the second water spray portion can be expected to decrease, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0052] According to the second embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion with a low flow rate is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion with a high flow rate. Therefore, even if a high temperature setting is erroneously performed, the temperature of the water sprayed with a low flow rate from the second water spray portion can be expected to decrease, reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0053] According to the third embodiment of another group of the present invention, the length of the second flow path portion from the cold and hot water mixing portion (hot water supply source) to the second water spray portion is longer than the length of the first flow path portion from the cold and hot water mixing portion (hot water supply source) to the first water spray portion. Therefore, even in the case of a high temperature setting by mistake, the temperature of the water sprayed from the second water spray portion without passing through the temperature reduction device can be expected to be reduced, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion can also be expected).

[0084] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0085] (Structure of the first embodiment)

[0086] Figure 1This is a schematic diagram of a shower device according to a first embodiment of the present invention.

[0087] like Figure 1 As shown, the shower device according to the first embodiment of the present invention includes: a first water spray unit 100 that sprays hot water toward a first water spray range corresponding to a user's head in a predetermined position 300; and a second water spray unit 200 that sprays hot water toward a second water spray range located below the first water spray range for the user. The "predetermined position" indicated by predetermined position 300 is, for example, an arbitrary position where the first water spray range (i.e., the spray range of hot water sprayed from the first water spray unit 100) and the second water spray range (i.e., the spray range of hot water sprayed from the second water spray unit 200) intersect when viewed from above.

[0088] The first water spray range is set to, for example, a height range of 120 cm to 130 cm. However, the first water spray range may be set and changed (adjustable) according to the height of the user.

[0089] Furthermore, the first water spray unit 100 and the second water spray unit 200 are arranged so as to face each other with the predetermined position 300 interposed therebetween. Furthermore, the first water spray unit 100 and the second water spray unit are arranged at substantially the same height. Here, "substantially the same" is defined as the height difference between the first and second water spray units being within 250 mm.

[0090] The first water spray unit 100 and the second water spray unit 200 can be fixed to the wall or ceiling of the shower room via various types of known support members. Alternatively, the first water spray unit 100 and the second water spray unit 200 can be directly fixed to the wall or ceiling of the shower room without using support members.

[0091] The first water spray unit 100 of this embodiment sprays hot water in the form of a mist in a triangular, solid, or hollow conical shape. Meanwhile, the second water spray unit 200 of this embodiment sprays hot water in a wave-like pattern across a roughly triangular area. Furthermore, the angle formed by the center direction of the water spray formed by the first water spray unit relative to the vertical direction (θ1: e.g., 2 to 90 degrees) is greater than the angle formed by the center direction of the water spray formed by the second water spray unit relative to the vertical direction (θ2: e.g., 1 to 35 degrees).

[0092] In this embodiment, the temperature of the hot water immediately after the first water spraying unit 100 and the temperature of the hot water immediately after the second water spraying unit 200 are both set to 39.8°C (e.g., Figure 4A and Figure 4B(As will be described later, the hot and cold water mixing valve can be unified.) However, the hot water sprayed in the form of mist from the first water spray unit 100 has a relatively small particle size, so the temperature drops significantly, and the hot water temperature when it reaches (impacts) the user's head is approximately 28.7°C (a relatively low temperature). On the other hand, the hot water sprayed in the form of waves from the second water spray unit 200 has a relatively large particle size, so the temperature drops less significantly, and the hot water temperature when it reaches (impacts) the front side of the user's body (from the head downward) is approximately 38.2°C (a relatively high temperature).

[0093] Furthermore, the operating unit 400 for inputting operations to the first and second water spray units 100 and 200 is provided on the same wall surface as the second water spray unit 200. That is, the first water spray unit 100 and the operating unit 400 are arranged facing each other with the predetermined position 300 interposed therebetween.

[0094] (Operation and Effect of the First Embodiment)

[0095] According to the first embodiment, the temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is lower than the temperature of the hot water reaching (impacting) the second water spray range below the first water spray range, thereby providing a shower device suitable for daytime relaxation.

[0096] The temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is relatively low, so the lower temperature hot water reaches the head (which is full of thick arteries) and the back just below the head (which is generally prone to sweating), thereby suppressing sweating.

[0097] On the other hand, by setting the temperature of the hot water reaching (impacting) the second water spray area, which is lower than the first water spray area, to be relatively high, the user can also enjoy a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0098] Furthermore, the first water spray unit 100 and the second water spray unit 200 are arranged to face each other with the predetermined position 300 interposed therebetween. That is, the second water spray range is a body part that is relatively less sensitive to heat (particularly the front of the body). Therefore, the user can more reliably feel the warmth of the body.

[0099] Furthermore, the first water spray section 100 and the second water spray section 200 are positioned at approximately the same height, and the center of the water spray from the first water spray section 100 is angled downward more gently than the center of the water spray from the second water spray section 200. Consequently, the hot water from the first water spray section 100 is easily sprayed locally toward the first water spray area corresponding to the user's head. Meanwhile, the hot water from the second water spray section 200 can be sprayed toward the second water spray area, which is located below the first water spray area, while being spread more widely than the water spray from the first water spray section 100. As a result, the hot water reaches a wider area of ​​the user's body, allowing the user to feel more reliably warmed.

[0100] Furthermore, the first water spray unit 100 and the operating unit 400 are arranged to face each other with the predetermined position 300 interposed therebetween. Therefore, while hot water from the first water spray unit 100 is sprayed to the first water spray range corresponding to the user's head, the user can easily see and operate the operating unit 400. Furthermore, the user's face can be prevented from being hit by cold hot water.

[0101] (Modification of the first embodiment)

[0102] The number of first water spray parts 100 is not limited to 1. For example, three first water spray parts 100 may be provided corresponding to the back of the head, the left back of the head, and the right back of the head, respectively.

[0103] The number of the second water spraying parts 200 is not limited to 1. For example, in order to spray water to a larger area on the front side of the user's body, a plurality of second water spraying parts 200 may be provided on the front side of the user's body.

[0104] And, as Figure 2 As shown, the second water spraying part 200 can be configured to spray hot water to the front, left and right sides of the user. Figure 2 As shown, a plurality of second water spraying parts 200 can be provided at appropriate intervals along the water supply passage configured as an elliptical semi-annular shape. According to this mode, hot water can reach the front, left and right sides of the user, so the user can feel the warmth of the body more reliably.

[0105] Furthermore, the first water spraying part 100 and the second water spraying part 200 can also be arranged at different heights. Figure 3 As shown, the second water spraying part 200 can be configured to spray hot water to the entire surrounding area (front, left, right and back) of the user. Figure 3 As shown, a plurality of second water spraying parts 200 can be provided at appropriate intervals along the water supply path configured as an elliptical ring. According to this mode, hot water can reach the front, left, right and rear sides of the user, so the user can feel the warmth of the body more reliably.

[0106] (Commonality of hot and cold water mixing valves)

[0107] In the first embodiment, as described above, the temperature of the hot water immediately after being sprayed from the first spray unit 100 and the temperature of the hot water immediately after being sprayed from the second spray unit 200 are both 39.8° C. Therefore, the hot water supplied to the first spray unit 100 and the hot water supplied to the second spray unit 200 can be made common.

[0108] That is, Figure 4A and Figure 4B As shown, a structure having the following parts can be adopted: a mixing valve 500, which is connected to a hot water supply pipe 510 and a cold water supply pipe 520 in order to generate hot water of a desired hot water temperature; a first flow path portion 110, which connects the mixing valve 500 and the first water spray portion 100; and a second flow path portion 210, which connects the mixing valve 500 and the second water spray portion 200.

[0109] In the first embodiment, the particle size of the hot water sprayed in a mist form from the first water spray unit 100 via the first flow path 110 is smaller than the particle size of the hot water sprayed in a wave form from the second water spray unit 200 via the second flow path 210. Therefore, the temperature of the hot water reaching (impacting) the user's head is approximately 28.7°C (lower), while the temperature of the hot water reaching (impacting) the front of the user's body (from the head downward) is approximately 38.2°C (higher).

[0110] In addition, Figure 4A In the structure shown, a flow regulating valve is provided in the region before the first flow path portion 110 and the second flow path portion 210 branch. Figure 4B In the illustrated structure, in addition to this, flow rate regulating valves are also provided midway between the first flow path portion 110 and the second flow path portion 210. Any of the above structures can be adopted.

[0111] (Structure of the Second Embodiment)

[0112] Next, a shower device according to a second embodiment of the present invention will be described with reference to the drawings.

[0113] Figure 5 It is a perspective view showing a state where a shower device according to a second embodiment of the present invention is installed in a shower room. Figure 6 It is a cross-sectional view showing an enlarged view of a shower head body of a shower device according to a second embodiment of the present invention.

[0114] like Figure 5As shown, the shower device 1 of this embodiment is fixed to the side wall surface 2a of the shower room 2. The shower device 1 also includes a shower head body 4 and a support member 6 for attaching the shower head body 4 to the side wall surface 2a.

[0115] The shower head body 4 is an elliptical ring-shaped member as a whole, and a plurality of water sprinkling parts are provided at intervals along the elliptical ring.

[0116] Furthermore, support member 6 is attached so as to extend generally horizontally from the upper portion of side wall surface 2a, and is configured to support shower head body 4 at a predetermined height. Furthermore, a water supply passage (not shown) is provided within support member 6, and hot and cold water supplied through this water supply passage flows into shower head body 4 and is sprayed from the various watering portions.

[0117] In this embodiment, the shower head body 4 is fixed to the side wall surface 2a via the support member 6 extending from the side wall surface 2a. However, the shower head body may be fixed to the ceiling surface via the support member extending from the ceiling surface. Alternatively, the shower head body may be fixed directly to the side wall surface or the ceiling surface without the support member.

[0118] Furthermore, the shower device 1 is configured so that, when in use, water is sprayed from each water sprinkling portion, so that a user standing under the shower head body 4 is showered from above by the shower water. Furthermore, the water sprinkling portions are provided along the annular shower head body 4, so that the shower water is formed by each water sprinkling portion so as to surround the head of the user standing under the shower head body 4.

[0119] Next, refer to Figure 6 The internal structure of the shower head body 4 will be described.

[0120] As described above, the shower head body 4 is formed as an elliptical ring as a whole. A water supply passage 4a extending along the ring is provided within the shower head body 4. Hot and cold water supplied via a water supply passage (not shown) formed within the support member 6 flows into the water supply passage 4a within the shower head body 4 and is supplied to the entire shower head body 4.

[0121] The shower head body 4 is also provided with a plurality of sprinkler mounting recesses 4b at regular intervals along the water supply passage 4a. These sprinkler mounting recesses 4b are cylindrical depressions extending vertically, communicating with the water supply passage 4a and opening toward the bottom surface of the shower head body 4. In other words, hot and cold water flowing through the water supply passage 4a of the shower head body 4 flows into the sprinkler mounting recesses 4b.

[0122] Furthermore, each of the watering unit mounting recesses 4b is fitted with a watering unit holding member 8. The watering unit holding member 8 is a cylindrical member and is watertightly mounted in each of the watering unit mounting recesses 4b.

[0123] Furthermore, a nozzle 18 serving as a watering unit is held in the watering unit holding member 8, which corresponds to the first watering unit of the present invention. This nozzle 18 is held by the watering unit holding member 8 so as to spray hot and cold water in the form of a mist from the lower surface of the watering unit holding member 8. Furthermore, the nozzle 18 is held by the watering unit holding member 8 so as to face obliquely downward. The nozzle 18 is directed toward the center of the oval shower head body 4 and sprays hot and cold water obliquely downward.

[0124] Figures 7 to 9 This figure shows an example of a nozzle 18 for realizing a shower spray in which hot and cold water spreads and falls in a mist form. Figure 7 It is a perspective view showing the entire nozzle. Figure 8 It is along Figure 7 A partial enlarged cross-sectional view of line VIII-VIII, Figure 9 It is along Figure 7 A partial enlarged cross-sectional view of line IX-IX.

[0125] like Figure 7 As shown, the nozzle 18 as the watering part is formed into a cylindrical shape as a whole, and can be embedded in each watering part mounting recess 4b of the shower head body 4 for use. Figures 7 to 9 As shown, a circular cross-sectional passage 18a is formed along the central axis of a cylindrical nozzle 18. Furthermore, a dome-shaped (hemispherical) inner wall surface 18b is formed at the distal end of this circular cross-sectional passage 18a. Furthermore, a V-shaped groove 18c is formed at the distal end of the nozzle 18. The deepest portion of this groove 18c is formed by cutting away a portion of the dome-shaped inner wall surface 18b.

[0126] With this structure, the hot and cold water guided by the water supply passage 4a in the shower head body 4 flows into the passage 18a of the nozzle 18, and the hot and cold water guided by the passage 18a flows out from the cutout provided in the inner wall surface 18b to the bottom of the V-shaped groove 18c, and flows downward ( Figures 7 to 9 Thus, as Figure 8 As shown, the hot and cold water W sprayed from the nozzles 18 falls as a cone or elliptical cone-shaped mist while expanding. Furthermore, in this embodiment, each nozzle 18 is attached to the shower head body 4 such that the major axis of the elliptical cone is tangential to the elliptical shower head body 4. Furthermore, in this embodiment, the shower head body 4 is provided with a water sprinkling unit by attaching the nozzles 18 thereto. However, the water sprinkling unit can also be provided by directly forming nozzle holes in the components constituting the shower head body 4.

[0127] Furthermore, the sprinkler holder 8, which corresponds to the second sprinkler of the present invention, holds a fluid element 10 serving as a sprinkler. The fluid element 10 is held by the sprinkler holder 8 so that hot and cold water are sprayed in a wave-like pattern from the lower surface of the sprinkler holder 8. Furthermore, the fluid element 10 is held by the sprinkler holder 8 so that it faces diagonally downward, and sprays hot and cold water diagonally downward toward the center of the oval shower head body 4.

[0128] Figures 10 to 12 This is a diagram showing an example of a fluid element 10 for realizing a shower water spray in a wave shape in which hot and cold water spreads and falls. Figure 10 It is an oblique view of the fluid element 10. Figure 11 It is along Figure 10 The cross-sectional view of line XI-XI, Figure 12 It is along Figure 8 Cross-sectional view along line XII-XII.

[0129] like Figure 10 As shown, the fluid element 10 is a thin, roughly rectangular parallelepiped component with a rectangular water outlet 10a on its front end and a flange 10b formed at its rear end. Furthermore, a groove 10c is provided parallel to the flange 10b, surrounding the circumference of the fluid element 10. An O-ring (not shown) is inserted into this groove 10c to ensure watertightness with the sprinkler retaining member 8.

[0130] like Figure 11 As shown, a passage with a rectangular cross section is formed to penetrate in the longitudinal direction inside the fluid element 10. The passage is formed into a water supply passage 12a, a vortex passage 12b, and a flow straightening passage 12c in order from the upstream side.

[0131] The water supply passage 12 a is a straight passage having a rectangular cross section with a constant cross-sectional area, extending from the inlet 10 d on the back side of the fluid element 10 .

[0132] Vortex passage 12b is a rectangular cross-section passageway provided downstream of water supply passage 12a, connected to water supply passage 12a (without a step). Specifically, the downstream end of water supply passage 12a and the upstream end of vortex passage 12b have the same dimensions and shape. The opposing walls (side walls) of vortex passage 12b are tapered so that the flow path cross-sectional area decreases downstream throughout vortex passage 12b. In other words, vortex passage 12b is tapered and gradually narrows in width toward the downstream side.

[0133] The rectifying passage 12c is a rectangular passage located downstream, communicating with the vortex passage 12b. Its cross-sectional area is constant and linear. The hot and cold water contained in the vortexes guided by the vortex passage 12b are rectified by the rectifying passage 12c and then discharged from the water outlet 10a. The cross-sectional area of ​​the rectifying passage 12c is smaller than that of the downstream end of the vortex passage 12b. A step 14 is formed between the vortex passage 12b and the rectifying passage 12c. The surface of the step 14, i.e., the wall surface, faces a direction perpendicular to the central axis of the vortex passage 12b.

[0134] On the other hand, Figure 12 As shown, the walls (ceiling and floor) of the water supply passage 12a, vortex passage 12b, and rectifying passage 12c that face each other in the height direction are all arranged on the same plane. In other words, the heights of the water supply passage 12a, vortex passage 12b, and rectifying passage 12c are all the same and constant.

[0135] Next, a hot / cold water collision section 16 is formed at the downstream end of the water supply passage 12a (near the connection between the water supply passage 12a and the vortex passage 12b). This collision section 16 is configured to partially block the flow path cross-section of the water supply passage 12a. This collision section 16 is a triangular prism-shaped portion that extends to connect the vertically opposing walls of the water supply passage 12a (the ceiling and the floor). It is positioned as an island in the center of the width of the water supply passage 12a. The cross-section of the collision section 16 is formed into an isosceles triangle, with its hypotenuse perpendicular to the central axis of the water supply passage 12a. Furthermore, the vertex of the isosceles triangle is positioned toward the downstream side.

[0136] By providing the hot and cold water collision portion 16, a Karman vortex is generated on the downstream side thereof, and the hot and cold water sprayed from the water spout 10a vibrates back and forth. That is, the hot and cold water supplied from the water supply passage (not shown) of the support member 6 flows into the water supply passage 4a ( Figure 6 ) and flows into the inlet 10d of each fluid element 10 held by the sprinkler retaining member 8. The cold and hot water flowing into the water supply passage 12a from the inlet 10d of each fluid element 10 collides with the cold and hot water collision portion 16, which is configured to partially block the flow path. This forms a vortex train of alternating counter-rotating Karman vortices downstream of the cold and hot water collision portion 16. The Karman vortices formed by the cold and hot water collision portion 16 grow while being guided by the vortex train passage 12b, which tapers to a tapered shape at the front end, before reaching the rectifying passage 12c.

[0137] The cold and hot water flowing into the rectifying passage 12c on the downstream side of the vortex passage 12b is rectified here. The cold and hot water sprayed from the water outlet 10a through the rectifying passage 12c is bent based on the flow velocity distribution in the water outlet 10a. Figure 11 The direction of the spray changes as it moves up and down. That is, the part with high flow rate of hot and cold water is located at Figure 11 When the hot and cold water are located at the upper end of the water outlet 10a, the hot and cold water are sprayed downward. When the high-velocity portion is located at the lower end of the water outlet 10a, the hot and cold water are sprayed upward. As described above, Karman vortices are alternately generated on the downstream side of the hot and cold water collision portion 16, thereby generating a flow velocity distribution in the water outlet 10a and deflecting the jet flow. In addition, the position of the high-velocity portion reciprocates due to the movement of the vortex train, so the sprayed hot and cold water also moves in a roughly predetermined vibration plane (similar to the vibration plane). Figure 11 It vibrates back and forth in a sinusoidal wave (in a wave form) in a plane parallel to the paper surface.

[0138] Here, as Figure 6 As shown, in this embodiment, each fluid element 10 is mounted obliquely downward. Therefore, the hot and cold water ejected from the water outlet 10a of each fluid element 10 falls while expanding in a fan-like pattern within a generally predetermined vibration plane. Furthermore, in this embodiment, each fluid element 10 is mounted to the shower head body 4 with its vibration plane oriented tangentially (circumferentially) to the elliptical shower head body 4. This creates a cylindrical shower jet with an elliptical cross-section beneath the shower head body 4 as a whole, enveloping the head of a user standing beneath the shower head body 4.

[0139] Next, refer to Figure 13 The operation of the shower device 1 according to the second embodiment of the present invention will be described.

[0140] Figure 13 This figure schematically shows a user who is showering with shower water ejected from the shower head body 4 of the shower device 1 according to the second embodiment of the present invention.

[0141] As described above, the hot and cold water sprayed from the nozzle 18 (first spray part) provided in the shower head body 4 is sprayed in the form of water mist. On the other hand, the hot and cold water sprayed from the fluid element 10 (second spray part) provided in the shower head body 4 is sprayed in the form of waves while reciprocating in a sinusoidal wave. Figure 13 As shown, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 are spread out in a roughly fan-shaped manner while falling. In addition, as described above, each nozzle 18 and each fluid element 10 are installed in a manner that is inclined downward toward the center of the shower head body 4 ( Figure 6). Therefore, the water spray space S surrounded by the shower water from each nozzle 18 and each fluid element 10 becomes narrower toward the bottom.

[0142] Furthermore, each nozzle 18 and each fluid element 10 is arranged at predetermined intervals along the annular shower head body 4. Figure 13 As shown, in the area (near the shower head body 4) where the width of the hot and cold water sprayed from the nozzles 18 and fluid elements 10 is not fully expanded, gaps exist between the hot and cold water sprayed from the nozzles 18 and fluid elements 10. This allows air within the spray space S surrounded by the shower water from the nozzles 18 and fluid elements 10 to flow out of the spray space S through the gaps between the shower water jets. Furthermore, in this embodiment, the shower head body 4 is annular, allowing air within the spray space S to flow upward through the inside of the shower head body 4. Consequently, the heat of the hot and cold water sprayed into the spray space S is not retained, maintaining a comfortable temperature within the spray space S.

[0143] Meanwhile, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 expands horizontally as it falls, forming a flat, fan-shaped stream as a whole. The fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 merge at a predetermined distance L after falling. Furthermore, the flat, fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 are directed tangentially to the annular shower head body 4. Therefore, the fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 surround the user's head and body, forming a film of water around the user's body. Therefore, the portion of the water spray space S above the predetermined distance L below the shower head body 4, due to the gaps between the shower water jets, functions as a heat release space. Furthermore, the portion of the water spray space S below the predetermined distance L below the shower head body 4, due to the convergence of the hot and cold water sprayed from each nozzle 18 and each fluid element 10, forms a film of water surrounding the user's body, thus functioning as a heat retention space.

[0144] As described above, the hot and cold water ejected from each nozzle 18 and each fluid element 10, after falling a predetermined distance L, forms a water film covering the user's upper body while striking the user's body. Therefore, the user's body is fully warmed by the hot and cold water. Therefore, even when the temperature in the shower room 2 is low, the user does not feel cold, and the user can shower for a long time.

[0145] According to the shower device of the second embodiment of the present invention, the shower head body 4 is fixed to the side wall surface 2a, allowing the user to shower without having to manually hold the shower head body 4. Furthermore, the multiple water spraying units, namely the nozzles 18 and the fluid elements 10, are spaced apart from each other on the shower head body 4. This creates gaps between the hot and cold water sprayed from the fluid elements 10 near the shower head body 4, preventing heat from stagnating within the spray space S surrounded by the shower water. This prevents users from feeling stuffy or having difficulty breathing during long showers. Furthermore, the hot and cold water sprayed from the nozzles 18 and fluid elements 10 spreads as it falls, impinging on a large area of ​​the user's body standing under the shower head body 4. The impinging hot and cold water further spreads across the body surface, effectively enveloping the user. As a result, even in cold temperatures, the user is less likely to feel cold while showering, allowing them to continue showering for extended periods.

[0146] In addition, according to the shower device of this embodiment, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 merge with each other at a position where they fall a predetermined distance L from each nozzle 18 and each fluid element 10 ( Figure 13 ), thus ensuring ventilation inside and outside the shower water space S surrounded by the shower water until the point where the hot and cold water merge, and thus preventing heat from stagnating. Furthermore, below the point where the hot and cold water merge, the user's body can be fully enveloped by the hot and cold water, thus being sufficiently warmed.

[0147] Furthermore, according to the shower device of this embodiment, the water spray space S surrounded by the sprayed hot and cold water narrows downward, thereby ensuring sufficient ventilation in the upper portion of the water spray space S. On the other hand, the space becomes smaller in the lower portion of the water spray space S, making it easier to ensure heat retention within the space and allowing the user to be fully warmed.

[0148] Furthermore, according to the shower device of this embodiment, the shower head body 4 is formed in an annular shape, so that the air in the water spray space S surrounded by the shower water flows out through the inside of the shower head body 4, thereby preventing the heat from stagnating in the water spray space S surrounded by the shower water.

[0149] Next, refer to Figure 14 A shower device according to a third embodiment of the present invention will be described.

[0150] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 2. Therefore, here, only the differences between the third embodiment of the present invention and the second embodiment will be described, and the description of the same structure, function, and effect will be omitted. Figure 14This is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the third embodiment of the present invention.

[0151] like Figure 14 As shown, the shower head body 20 of the shower device involved in the third embodiment of the present invention is configured in a rectangular ring shape. A plurality of sprinklers are provided along the shower head body 20 configured in the ring shape, forming a shower water jet that surrounds the user's head. The hot and cold water sprayed from each sprinkler is configured to expand into a flat fan shape while falling. In addition, each shower water jet expanded into a fan shape is directed in a direction parallel to each side of the shower head body 20, and merges with each other at a position a predetermined distance below each sprinkler, forming a water film around the user's body. Furthermore, each sprinkler is installed obliquely downward in such a manner that each shower water jet is directed toward the center of the shower head body 20, and the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, as a plurality of sprinklers provided on the shower head body 20, it is possible to adopt a plurality of sprinklers by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0152] Next, refer to Figure 15 A shower device according to a fourth embodiment of the present invention will be described.

[0153] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 2. Therefore, here, only the differences between the fourth embodiment of the present invention and the second embodiment will be described, and the description of the same structure, function, and effect will be omitted. Figure 15 This is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the fourth embodiment of the present invention.

[0154] like Figure 15 As shown, the shower head body 30 of the shower device according to the fourth embodiment of the present invention is composed of two linear shower head bodies 30a and 30b. Multiple sprinklers are arranged along each of these linear shower head bodies 30a and 30b, forming a shower spray that surrounds the user's head. The hot and cold water sprayed from each sprinkler falls while expanding into a flattened fan-shaped pattern. Furthermore, the sprinklers arranged in the center of each shower head body 30a and 30b spray a fan-shaped shower spray parallel to the direction in which the shower head bodies 30a and 30b extend. In contrast, the sprinklers arranged near the ends of each shower head body 30a and 30b spray a fan-shaped shower spray at a substantially right angle to the direction in which the shower head bodies 30a and 30b extend.

[0155] Furthermore, the sprinklers provided on each shower head main body 30a, 30b spray hot and cold water diagonally downward in a direction in which the shower water sprayed approaches each other. Therefore, the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, the shower water sprayed from each sprinkler provided near the end of the shower head main body 30a and 30b is directed to merge with each other at a position where it falls a predetermined distance. Therefore, the shower water sprayed from the two shower head main bodies 30a, 30b configured in a straight line will surround the head of the user standing between the two shower head main bodies 30a, 30b. In addition, as a plurality of sprinklers provided on the shower head main body 30, it is possible to adopt a plurality of sprinklers provided on the shower head main body 30 by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0156] Next, refer to Figure 16 A shower device according to a fifth embodiment of the present invention will be described.

[0157] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 2. Therefore, only the differences between the fifth embodiment of the present invention and the second embodiment will be described here, and the description of the same structures, functions, and effects will be omitted. Figure 16 This is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the fifth embodiment of the present invention.

[0158] like Figure 16 As shown, the shower head body 40 of the shower device according to the fifth embodiment of the present invention comprises two curved, extended shower head bodies 40a and 40b. These shower head bodies 40a and 40b curve and extend so that their ends approach each other. Multiple sprinklers are provided along the shower head bodies 40a and 40b. This creates a shower spray that surrounds the user's head. The hot and cold water sprayed from each sprinkler falls while expanding into a flattened fan-shaped pattern. Furthermore, the sprinklers provided in the center of each shower head body 40a and 40b spray a fan-shaped shower spray that expands tangentially to the direction in which each shower head body 40a and 40b extends. In contrast, the sprinklers provided near the ends of each shower head body 40a and 40b spray a fan-shaped shower spray at an angle approximately perpendicular to the direction in which each shower head body 40a and 40b extends.

[0159] Furthermore, the sprinklers provided on each shower head main body 40a, 40b spray hot and cold water diagonally downward in a direction in which the shower water sprayed approaches each other. Therefore, the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, the shower water sprayed from each sprinkler provided near the end of the shower head main body 40a and 40b is directed to merge with each other at a position where it falls a predetermined distance. Therefore, the shower water sprayed from the two curved shower head main bodies 40a, 40b will surround the head of the user standing between the two shower head main bodies 40a, 40b. In addition, as a plurality of sprinklers provided on the shower head main body 40, it is possible to adopt a plurality of sprinklers provided on the shower head main body 40 by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0160] Furthermore, in each of the above embodiments, the particle size of the hot water sprayed from the first water spraying portion via the first flow path portion is smaller than the particle size of the hot water sprayed from the second water spraying portion via the second flow path portion. This configuration allows the temperature of the hot water sprayed from the first water spraying portion to be lower when it reaches the user than when it reaches the user from the second water spraying portion. However, the present invention is not limited to this configuration. For example, the temperature of the hot water sprayed from the first water spraying portion itself may be lowered compared to the temperature of the hot water sprayed from the second water spraying portion, thereby allowing the temperature of the hot water sprayed from the first water spraying portion to be lower when it reaches the user than when it reaches the user from the second water spraying portion.

[0186] Feature 8

[0187] The water spray device according to any one of features 1 to 7 is characterized in that it further comprises:

[0188] a mixing valve connected to the cold water supply pipe and the hot water supply pipe for generating the hot water;

[0189] a first flow path portion connecting the mixing valve and the first water spray portion; and

[0190] The second flow path portion connects the mixing valve and the second water spray portion.

[0191] The particle size of the hot water sprayed from the first water spraying portion through the first flow path portion is smaller than the particle size of the hot water sprayed from the second water spraying portion through the second flow path portion.

[0192] Next, another group of embodiments of the present invention will be described. The same reference numerals are used for the same (common) structural elements and parts as those of the aforementioned group of embodiments of the present invention. In the case of common content, reference is made to the same drawings.

[0193] (Structure of the Sixth Embodiment)

[0194] Figure 17 This is a schematic diagram of a shower device according to a sixth embodiment of the present invention.

[0195] like Figure 17 As shown, a shower device according to a sixth embodiment of the present invention includes: a first water spray unit 100 that sprays hot water toward a first water spray range corresponding to a user's head in a predetermined position 300; and a second water spray unit 200 that sprays hot water toward a second water spray range located below the first water spray range for the user. The "predetermined position" indicated by predetermined position 300 is, for example, an arbitrary position where the first water spray range (i.e., the spray range of hot water sprayed from the first water spray unit 100) and the second water spray range (i.e., the spray range of hot water sprayed from the second water spray unit 200) intersect when viewed from above.

[0196] The first water spray range is set to, for example, a height range of 120 cm to 130 cm. However, the first water spray range may be set and changed (adjustable) to match the height of the user.

[0197] Furthermore, the first water spray unit 100 and the second water spray unit 200 are arranged so as to face each other with the predetermined position 300 interposed therebetween. Furthermore, the first water spray unit 100 and the second water spray unit are arranged at substantially the same height. Here, "substantially the same" is defined as the height difference between the first and second water spray units being within 250 mm.

[0198] The first water spray unit 100 and the second water spray unit 200 can be fixed to the wall or ceiling of the shower room via various types of known support members. Alternatively, the first water spray unit 100 and the second water spray unit 200 can be directly fixed to the wall or ceiling of the shower room without using support members.

[0199] The first water spray unit 100 of this embodiment sprays hot water in the form of a mist in a triangular, solid, or hollow conical shape. Meanwhile, the second water spray unit 200 of this embodiment sprays hot water in a wave-like pattern across a roughly triangular area. Furthermore, the angle formed by the center direction of the water spray formed by the first water spray unit relative to the vertical direction (θ1: e.g., 2 to 90 degrees) is greater than the angle formed by the center direction of the water spray formed by the second water spray unit relative to the vertical direction (θ2: e.g., 1 to 35 degrees).

[0200] In this embodiment, the hot water temperature immediately after the first water spraying unit 100 and the hot water temperature immediately after the second water spraying unit 200 are both set to 39.8°C during a stable hot water flow. Figure 18A and Figure 18B As shown, the hot and cold water mixing valve 500 is unified. However, the hot water sprayed in the form of mist from the first water spray unit 100 has a relatively small particle size, so the temperature drops significantly. When it reaches (impacts) the user's head, the temperature is approximately 28.7°C (a relatively low temperature). Meanwhile, the hot water sprayed in the form of waves from the second water spray unit 200 has a relatively large particle size, so the temperature drops less significantly. When it reaches (impacts) the front side of the user's body (from the head downward), the temperature is approximately 38.2°C (a relatively high temperature).

[0201] In this embodiment, if Figure 18A and Figure 18B As shown, a structure having the following parts can be adopted: a mixing valve 500 connected to a hot water supply pipe 510 and a cold water supply pipe 520 to generate hot water of a desired hot water temperature; a first flow path portion 110 connecting the mixing valve 500 and the first water spraying portion 100; and a second flow path portion 210 connecting the mixing valve 500 and the second water spraying portion 200. In addition, Figure 18A In the structure shown, a flow regulating valve is provided in the region before the first flow path portion 110 and the second flow path portion 210 branch. Figure 18B In the illustrated structure, in addition to this, flow rate regulating valves are also provided midway between the first flow path portion 110 and the second flow path portion 210. Any of the above structures can be adopted.

[0202] In addition, in this embodiment, the first flow path portion 110 and the second flow path portion 210 have a common portion 530 on the hot and cold water mixing valve 500 side, and are branched through a branch portion 550 (see Figure 18A and Figure 18B ). In addition, a plurality of second water spraying parts 200 can be provided, and a second branching part 215 can be provided between the plurality of second water spraying parts 200 and the branching part 550. For example, Figure 19As shown, the second flow path portion 210 reaching the plurality of second water spray parts 200 can be formed in a substantially T-shaped manner in a plan view and having one second branch portion 215 .

[0203] Furthermore, in this embodiment, the length of the second flow path portion 210 from the hot and cold water mixing valve 500 to the second water spraying portion 200 is longer than the length of the first flow path portion 110 from the hot and cold water mixing valve 500 to the first water spraying portion 100 (see FIG. Figure 17 and Figure 19 ).

[0204] (Operation and Effect of the Sixth Embodiment)

[0205] According to the sixth embodiment, the temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is lower than the temperature of the hot water reaching (impacting) the second water spray range below the first water spray range, thereby providing a shower device suitable for daytime rest.

[0206] The temperature of the hot water reaching (impacting) the first water spray range corresponding to the user's head is relatively low, so the lower temperature hot water reaches the head (which is full of thick arteries) and the back just below the head (which is generally prone to sweating), thereby suppressing sweating.

[0207] On the other hand, by setting the temperature of the hot water reaching (impacting) the second water spray area, which is lower than the first water spray area, to be relatively high, the user can also enjoy a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0208] Furthermore, the first water spray unit 100 and the second water spray unit 200 are arranged to face each other with the predetermined position 300 interposed therebetween. That is, the second water spray range is a body part that is relatively less sensitive to heat (particularly the front of the body). Therefore, the user can more reliably feel the warmth of the body.

[0209] Furthermore, the first and second water spray sections 100 and 200 are positioned at approximately the same height. The center of the water spray from the first water spray section 100 is angled downward more gently than the center of the water spray from the second water spray section 200. Consequently, the hot water from the first water spray section 100 is more easily sprayed locally toward the first water spray area corresponding to the user's head. Meanwhile, the hot water from the second water spray section 200 can be sprayed toward the second water spray area, which is located below the first water spray area, while spreading more widely than the water spray from the first water spray section 100. This allows the hot water to reach a wider area of ​​the user's body, ensuring the user feels more reliably warmed. Furthermore, even if the temperature is mistakenly set to a high temperature, the water (hot water) sprayed from the second water spray section 200 is accelerated to cool in the air.

[0210] Furthermore, the length of the second flow path 210 from the mixing valve 500 to the second water spray section 200 is longer than the length of the first flow path 110 from the mixing valve 500 to the first water spray section 100. Therefore, even if a high temperature setting is mistakenly made, the temperature of the large-particle water sprayed from the second water spray section 200 can be expected to be lower, thereby reducing the risk of burns to the user. (In addition to the heat conduction (heat dissipation) effect of the longer second flow path 210 itself, the temperature can also be expected to be lowered by the (low-temperature) residual hot water remaining in the longer second flow path 210.) Specifically, when hot water is supplied with a set temperature of 50°C and the temperature of the residual hot water is approximately 25°C (around room temperature), even if the hot water temperature immediately after being sprayed from the first water spray section 100 is as high as approximately 44°C, the hot water temperature immediately after being sprayed from the second water spray section 200 will drop to approximately 40°C.

[0211] (Variation of the Sixth Embodiment)

[0212] The number of the first water spray parts 100 is not limited to 1. For example, three first water spray parts 100 may be provided corresponding to the back of the head, the left back of the head, and the right back of the head, respectively.

[0213] The number of the second water spraying parts 200 is not limited to one. Figure 19 As shown, in order to spray water to a larger area of ​​the front side of the user's body, a plurality of spray nozzles can be provided on the front side of the user's body.

[0214] And, as Figure 20 As shown, the second water spraying part 200 can be configured to spray hot water to the front, left and right sides of the user. Figure 20As shown, a plurality of second water spraying parts 200 can be provided at appropriate intervals along the water supply passage configured as an elliptical semi-annular shape. According to this mode, hot water can reach the front, left and right sides of the user, so the user can feel the warmth of the body more reliably.

[0215] Furthermore, the first water spraying part 100 and the second water spraying part 200 can also be arranged at different heights. Figure 21 As shown, the second water spraying part 200 can be configured to spray hot water to the entire surrounding area (front, left, right and back) of the user. Figure 21 As shown, a plurality of second water spraying parts 200 can be provided at appropriate intervals along the water supply path configured as an elliptical ring. According to this mode, hot water can reach the front, left, right and rear sides of the user, so the user can feel the warmth of the body more reliably.

[0216] In addition, in this case, Figure 22A As shown, the second flow path portion 210 reaching the plurality of second spray units 200 may have a single second branch portion 215 ′ that resembles a map mark of a fire station when viewed from above.

[0217] Or, in this case, Figure 22B and Figure 22C As shown, the second flow path portion 210 reaching multiple second water spray portions 200 can be adopted in a manner having second branch portions 216, 216' that branch radially above the user's head and third branch portions 217, 218, 217', 218', 217", 218" that further branch the branched radial flow paths in two directions of the annular flow path.

[0218] (Structure of the Seventh Embodiment)

[0219] Figure 23 This is a schematic diagram of a shower device according to a seventh embodiment of the present invention.

[0220] like Figure 23 As shown, the shower device of the seventh embodiment of the present invention includes: a first water spray part 100', which sprays hot water toward a first water spray range corresponding to the head of a user in a predetermined position 300; and a second water spray part 200', which sprays hot water toward a second water spray range below the first water spray range for the user.

[0221] As in the sixth embodiment, the first water spray range is set to a height range of, for example, 120 cm to 130 cm. However, the first water spray range may be set and changed (adjustable) to suit the height of the user.

[0222] Also, similarly to the sixth embodiment, the first water spray unit 100' and the second water spray unit 200' are disposed facing each other with the predetermined position 300 interposed therebetween. Furthermore, the first water spray unit 100' and the second water spray unit 200' are disposed at substantially the same height.

[0223] Furthermore, similar to the sixth embodiment, the first water spray unit 100' and the second water spray unit 200' can be fixed to the wall or ceiling of the shower room via various types of known support members. Alternatively, the first water spray unit 100' and the second water spray unit 200' can be directly fixed to the wall or ceiling of the shower room without using support members.

[0224] The first water spray section 100' of this embodiment is a shower spray section with relatively small opening diameters, spraying hot water at a relatively high flow rate (e.g., 2.0 m / s to 8.0 m / s). Meanwhile, the second water spray section 200' of this embodiment is a shower spray section with relatively large opening diameters, spraying hot water at a relatively low flow rate (e.g., 1.0 m / s to 4.0 m / s). Furthermore, the angle formed by the center direction of the water spray formed by the first water spray section 100' with respect to the vertical direction (θ1: e.g., 2 to 90 degrees) is larger than the angle formed by the center direction of the water spray formed by the second water spray section 200' with respect to the vertical direction (θ2: e.g., 1 to 35 degrees).

[0225] In this embodiment, the hot water temperature immediately after the first water spraying unit 100' and the hot water temperature immediately after the second water spraying unit 200' are both set to 39.8°C when the hot water is supplied stably. Figure 18A and Figure 18B As shown, the hot and cold water mixing valve 500 can be unified. However, the hot water sprayed from the first spray unit 100' in a shower mode has a relatively high flow rate, so the temperature drops significantly, and the hot water temperature when it reaches (impacts) the user's head is approximately 28.7°C (a relatively low temperature). On the other hand, the hot water sprayed from the second spray unit 200' in a shower mode has a relatively low flow rate, so the temperature drops less significantly, and the hot water temperature when it reaches (impacts) the front side of the user's body (from the head downward) is approximately 38.2°C (a relatively high temperature).

[0226] In this embodiment, Figure 18A and Figure 18B As shown, a structure having the following parts can be adopted: a mixing valve 500, which is connected to a hot water supply pipe 510 and a cold water supply pipe 520 in order to generate hot water of a desired hot water temperature; a first flow path portion 110, which connects the mixing valve 500 and the first water spray portion 100'; and a second flow path portion 210, which connects the mixing valve 500 and the second water spray portion 200'.

[0227] In addition, in this embodiment, the first flow path portion 110 and the second flow path portion 210 also have a common portion 530 on the hot and cold water mixing valve 500 side, and are branched through a branch portion 550 (see Figure 18A and Figure 18B ). In addition, a plurality of second water spraying parts 200' can be provided, and a second branching part 215 can be provided between the plurality of second water spraying parts 200' and the branching part 550. For example, Figure 19 As shown, the second flow path portion 210 reaching the plurality of second spray parts 200 ′ can be formed in a substantially T-shaped manner in a plan view having one second branch portion 215 .

[0228] Furthermore, in this embodiment, the length of the second flow path portion 210 from the hot and cold water mixing valve 500 to the second water spraying portion 200' is longer than the length of the first flow path portion 110 from the hot and cold water mixing valve 500 to the first water spraying portion 100' (see FIG. Figure 23 and Figure 19 ).

[0229] (Effects of the Seventh Embodiment)

[0230] The seventh embodiment also achieves substantially the same effects as those achieved with the sixth embodiment. Specifically, the temperature of the hot water reaching (impacting) the first water jet range corresponding to the user's head is lower than the temperature of the hot water reaching (impacting) the second water jet range, located below the first water jet range. This allows for a shower device suitable for daytime relaxation. Furthermore, the relatively low temperature of the hot water reaching (impacting) the first water jet range corresponding to the user's head allows the lowered temperature hot water to reach the head (which is covered with thick arteries) and the back directly below the head (which is generally prone to sweating), thereby suppressing sweating. Meanwhile, by setting the temperature of the hot water reaching (impacting) the second water jet range, located below the first water jet range, to be relatively high, the user can also experience a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0231] Furthermore, the first water spray section 100' and the second water spray section 200' are positioned opposite each other with the predetermined position 300 interposed between them. This means that the second water spray area is targeted at a body area that is less sensitive to heat (particularly the front of the body). Therefore, the user can more reliably feel the warmth of their body. Furthermore, the first water spray section 100' and the second water spray section 200' are positioned at approximately the same height. The center of the water spray from the first water spray section 100' is angled downward more gently than the center of the water spray from the second water spray section 200'. This allows the hot water from the first water spray section 100' to be sprayed locally toward the first water spray area corresponding to the user's head. Meanwhile, the hot water from the second water spray section 200' can be sprayed toward the second water spray area, which is located below the first water spray area, while being spread out more widely than the water spray from the first water spray section 100'. This allows the hot water to reach a wider area of ​​the user's body, allowing the user to more reliably feel the warmth of their body. Furthermore, even when a high temperature setting is made by mistake, it is possible to promote a decrease in the temperature of the spray water (hot water) in the air from the second spray water part 200 ′.

[0232] Furthermore, the length of the second flow path 210 from the mixing valve 500 to the second water spray section 200' is longer than the length of the first flow path 110 from the mixing valve 500 to the first water spray section 100'. Therefore, even if a high temperature setting is mistakenly made, the temperature of the water sprayed from the second water spray section 200', which has a low flow rate, can be expected to be lower, thereby reducing the risk of burns to the user. (In addition to the heat conduction (heat dissipation) effect of the longer second flow path 210 itself, the temperature can also be expected to be lowered by the (low-temperature) residual hot water remaining in the longer second flow path 210.) Specifically, when hot water is supplied with a set temperature of 50°C and the temperature of the residual hot water is approximately 25°C (around room temperature), even if the hot water temperature immediately after being sprayed from the first water spray section 100' is as high as approximately 44°C, the hot water temperature immediately after being sprayed from the second water spray section 200' will drop to approximately 40°C.

[0233] (Structure of the Eighth Embodiment)

[0234] Figure 24 This is a schematic diagram of a shower device according to an eighth embodiment of the present invention.

[0235] like Figure 24 As shown, the shower device of the eighth embodiment of the present invention comprises: a first water spray portion 100", which sprays hot water toward a first water spray range corresponding to the head of a user in a specified position 300; and a second water spray portion 200", which sprays hot water toward a second water spray range below the first water spray range for the user.

[0236] As in the sixth and seventh embodiments, the first water spray range is set to a height range of, for example, 120 cm to 130 cm. However, the first water spray range may be set and changed (adjustable) to suit the height of the user.

[0237] In addition, similarly to the sixth and seventh embodiments, the first water spray section 100 ″ and the second water spray section 200 ″ are arranged to face each other with the predetermined position 300 interposed therebetween. In addition, the first water spray section 100 ″ and the second water spray section 200 ″ are arranged at approximately the same height position.

[0238] In addition, similar to the sixth and seventh embodiments, the first water spray section 100" and the second water spray section 200" can be fixed to the wall surface and ceiling surface of the shower room via various types of well-known support components. Alternatively, the first water spray section 100" and the second water spray section 200" can also be directly fixed to the wall surface and ceiling surface of the shower room without using support components.

[0239] The first water spray section 100" of the present embodiment sprays hot water in a wave-like manner through a roughly triangular-shaped area, but a fan device 600 (an example of a temperature reducing device) is provided nearby to actively reduce the temperature of the hot water immediately after being sprayed from the first water spray section 100" (to reduce the temperature to the same level as when spraying water in a mist form). On the other hand, the second water spray section 200" of the present embodiment sprays hot water in a wave-like manner through a roughly triangular-shaped area. Moreover, the angle formed by the center direction of the water spray formed by the first water spray section 100" with respect to the vertical direction (θ1: for example, 2 to 90 degrees) is larger than the angle formed by the center direction of the water spray formed by the second water spray section 200" with respect to the vertical direction (θ2: for example, 1 to 35 degrees).

[0240] In this embodiment, the hot water temperature immediately after water is sprayed from the first water spraying part 100" and the hot water temperature immediately after water is sprayed from the second water spraying part 200' are both set to 39.8°C when hot water is supplied stably. Figure 18A and Figure 18B As shown, the hot and cold water mixing valve 500 can be unified. However, the hot water sprayed from the first water spray unit 100" in a shower-like manner experiences a significant temperature drop due to the action of the fan device 600, and the hot water temperature when it reaches (impacts) the user's head is approximately 28.7°C (a relatively low temperature). On the other hand, the hot water sprayed from the second water spray unit 200' in a wave-like pattern experiences a smaller temperature drop due to its relatively low flow rate, and the hot water temperature when it reaches (impacts) the front side of the user's body (from the head downward) is approximately 38.2°C (a relatively high temperature).

[0241] In this embodiment, Figure 18A and Figure 18B As shown, a structure having the following parts can be adopted: a mixing valve 500, which is connected to a hot water supply pipe 510 and a cold water supply pipe 520 in order to generate hot water of a desired hot water temperature; a first flow path portion 110, which connects the mixing valve 500 and a first water spray portion 100"; and a second flow path portion 210, which connects the mixing valve 500 and a second water spray portion 200".

[0242] In addition, in this embodiment, the first flow path portion 110 and the second flow path portion 210 also have a common portion 530 on the hot and cold water mixing valve 500 side, and are branched through a branch portion 550 (see Figure 18A and Figure 18B ). In addition, a plurality of second water spraying parts 200" can be provided, and a second branching part 215 can be provided between the plurality of second water spraying parts 200" and the branching part 550. For example, Figure 19 As shown, the second flow path portion 210 reaching the plurality of second water spraying portions 200 ″ can be formed in a substantially T-shaped manner in a plan view and having one second branch portion 215 .

[0243] Furthermore, in this embodiment, the length of the second flow path portion 210 from the hot and cold water mixing valve 500 to the second water spray portion 200" is longer than the length of the first flow path portion 110 from the hot and cold water mixing valve 500 to the first water spray portion 100" (see FIG. Figure 24 and Figure 19 ).

[0244] (Effects of the Eighth Embodiment)

[0245] The eighth embodiment also achieves substantially the same effects as those achieved by the sixth and seventh embodiments. Specifically, the temperature of the hot water reaching (impacting) the first water jet area corresponding to the user's head is lower than the temperature of the hot water reaching (impacting) the second water jet area, located below the first water jet area. This allows for a shower device suitable for daytime relaxation. Furthermore, the relatively low temperature of the hot water reaching (impacting) the first water jet area corresponding to the user's head allows the lowered temperature hot water to reach the head (which is covered with thick arteries) and the back directly below the head (which is generally prone to sweating), thereby suppressing sweating. Meanwhile, by setting the temperature of the hot water reaching (impacting) the second water jet area, located below the first water jet area, to be relatively high, the user can also experience a comfortable warming effect. In other words, it is possible to achieve both sweat suppression and body warmth, providing a shower device suitable for daytime relaxation.

[0246] In addition, the first water spray part 100" and the second water spray part 200" are arranged to face each other with the specified position 300 sandwiched therebetween, that is, the second water spray range becomes a part of the body that is relatively insensitive to heat (particularly the front side of the body). Therefore, the user can feel the warmth of the body more reliably. In addition, the first water spray section 100" and the second water spray section 200" are arranged at approximately the same height position, and the water spray center direction formed by the first water spray section 100" is more gently angled downward than the water spray center direction formed by the second water spray section 200". Therefore, the hot water from the first water spray section 100" can be easily sprayed locally toward the first water spray range corresponding to the user's head. On the other hand, the hot water from the second water spray section 200" can be sprayed toward the second water spray range below the first water spray range while being greatly expanded compared to the water spray from the first water spray section 100". Therefore, the hot water reaches a wider range of the user's body parts, and the user can feel the warmth of the body more reliably. In addition, even if a high temperature setting is made by mistake, the temperature of the water (hot water) sprayed from the second water spray section 200" in the air can be promoted to be lowered.

[0247] Furthermore, the length of the second flow path portion 210 from the mixing valve 500 to the second water spray portion 200" is longer than the length of the first flow path portion 110 from the mixing valve 500 to the first water spray portion 100". Therefore, even if a high temperature setting is made by mistake, the temperature of the water sprayed from the second water spray portion 200" without passing through the fan device 600 can be expected to decrease, thereby reducing the risk of scalding to the user (in addition to the heat conduction (heat dissipation) effect of the longer second flow path portion 210 itself, the temperature can also be expected to be reduced by the (low-temperature) residual hot water remaining in the longer second flow path portion 210). Specifically, when hot water is supplied with a set temperature of 50°C, if the temperature of the residual hot water is around 25°C (around room temperature), then even if the temperature of the hot water immediately after being sprayed from the first water spray portion 100" becomes as high as around 44°C, the temperature of the hot water immediately after being sprayed from the second water spray portion 200" will drop to around 40°C.

[0248] (Structure of the Ninth Embodiment)

[0249] Next, a shower device according to a ninth embodiment of the present invention will be described with reference to the drawings.

[0250] The aforementioned Figure 5 Still another perspective view shows a state where the shower device according to the ninth embodiment of the present invention is installed in a shower room. Figure 5 The following is a cross-sectional view showing an enlarged view of the shower head main body of the shower device according to the ninth embodiment of the present invention.

[0251] like Figure 5 As shown, the shower device 1 of this embodiment is fixed to the side wall surface 2a of the shower room 2. The shower device 1 also includes a shower head body 4 and a support member 6 for attaching the shower head body 4 to the side wall surface 2a.

[0252] The shower head body 4 is an elliptical ring-shaped member as a whole, and a plurality of water sprinkling parts are provided at intervals along the elliptical ring.

[0253] Furthermore, support member 6 is attached so as to extend generally horizontally from the upper portion of side wall surface 2a, and is configured to support shower head body 4 at a predetermined height. Furthermore, a water supply passage (not shown) is provided within support member 6, and hot and cold water supplied through this water supply passage flows into shower head body 4 and is sprayed from the various watering portions.

[0254] In this embodiment, the shower head body 4 is fixed to the side wall surface 2a via the support member 6 extending from the side wall surface 2a. However, the shower head body may be fixed to the ceiling surface via the support member extending from the ceiling surface. Alternatively, the shower head body may be fixed directly to the side wall surface or the ceiling surface without the support member.

[0255] Furthermore, the shower device 1 is configured so that, when in use, water is sprayed from each water sprinkling portion, so that a user standing under the shower head body 4 is showered from above by the shower water. Furthermore, the water sprinkling portions are provided along the annular shower head body 4, so that the shower water is formed by each water sprinkling portion so as to surround the head of the user standing under the shower head body 4.

[0256] Next, refer to the aforementioned Figure 6 The internal structure of the shower head body 4 will be described.

[0257] As described above, the shower head body 4 is formed as an elliptical ring as a whole. A water supply passage 4a extending along the ring is provided within the shower head body 4. Hot and cold water supplied via a water supply passage (not shown) formed within the support member 6 flows into the water supply passage 4a within the shower head body 4 and is supplied to the entire shower head body 4.

[0258] The shower head body 4 is also provided with a plurality of sprinkler mounting recesses 4b at regular intervals along the water supply passage 4a. These sprinkler mounting recesses 4b are cylindrical depressions extending vertically, communicating with the water supply passage 4a and opening toward the bottom surface of the shower head body 4. In other words, hot and cold water flowing through the water supply passage 4a of the shower head body 4 flows into the sprinkler mounting recesses 4b.

[0259] Furthermore, each of the watering unit mounting recesses 4b is fitted with a watering unit holding member 8. The watering unit holding member 8 is a cylindrical member and is watertightly mounted in each of the watering unit mounting recesses 4b.

[0260] Furthermore, a nozzle 18 serving as a watering unit is held in the watering unit holding member 8, which corresponds to the first watering unit of the present invention. This nozzle 18 is held by the watering unit holding member 8 so as to spray hot and cold water in the form of a mist from the lower surface of the watering unit holding member 8. Furthermore, the nozzle 18 is held by the watering unit holding member 8 so as to face obliquely downward. The nozzle 18 is directed toward the center of the oval shower head body 4 and sprays hot and cold water obliquely downward.

[0261] Figures 7 to 9 This figure shows an example of a nozzle 18 for realizing a shower spray in which hot and cold water spreads and falls in a mist form. Figure 7 It is a perspective view showing the entire nozzle. Figure 8 It is along Figure 7 A partial enlarged cross-sectional view of line VIII-VIII, Figure 9 It is along Figure 7 A partial enlarged cross-sectional view of line IX-IX.

[0262] like Figure 7 As shown, the nozzle 18 as the watering part is formed into a cylindrical shape as a whole, and can be embedded in each watering part mounting recess 4b of the shower head body 4 for use. Figures 7 to 9 As shown, a circular cross-sectional passage 18a is formed along the central axis of a cylindrical nozzle 18. Furthermore, a dome-shaped (hemispherical) inner wall surface 18b is formed at the distal end of this circular cross-sectional passage 18a. Furthermore, a V-shaped groove 18c is formed at the distal end of the nozzle 18. The deepest portion of this groove 18c is formed by cutting away a portion of the dome-shaped inner wall surface 18b.

[0263] With this structure, the hot and cold water guided by the water supply passage 4a in the shower head body 4 flows into the passage 18a of the nozzle 18, and the hot and cold water guided by the passage 18a flows out from the cutout provided in the inner wall surface 18b to the bottom of the V-shaped groove 18c, and flows downward ( Figures 7 to 9 Thus, as Figure 8 As shown, the hot and cold water W sprayed from the nozzles 18 falls as a cone or elliptical cone-shaped mist while expanding. Furthermore, in this embodiment, each nozzle 18 is attached to the shower head body 4 such that the major axis of the elliptical cone is tangential to the elliptical shower head body 4. Furthermore, in this embodiment, the shower head body 4 is provided with a water sprinkling unit by attaching the nozzles 18 thereto. However, the water sprinkling unit can also be provided by directly forming nozzle holes in the components constituting the shower head body 4.

[0264] Furthermore, the sprinkler holder 8, which corresponds to the second sprinkler of the present invention, holds a fluid element 10 serving as a sprinkler. The fluid element 10 is held by the sprinkler holder 8 so that hot and cold water are sprayed in a wave-like pattern from the lower surface of the sprinkler holder 8. Furthermore, the fluid element 10 is held by the sprinkler holder 8 so that it faces diagonally downward, and sprays hot and cold water diagonally downward toward the center of the oval shower head body 4.

[0265] Figures 10 to 12 This is a diagram showing an example of a fluid element 10 for realizing a shower water spray in a wave shape in which hot and cold water spreads and falls. Figure 10 It is an oblique view of the fluid element 10. Figure 11 It is along Figure 10 The cross-sectional view of line XI-XI, Figure 12 It is along Figure 8 Cross-sectional view along line XII-XII.

[0266] like Figure 10 As shown, the fluid element 10 is a thin, roughly rectangular parallelepiped component with a rectangular water outlet 10a on its front end and a flange 10b formed at its rear end. Furthermore, a groove 10c is provided parallel to the flange 10b, surrounding the circumference of the fluid element 10. An O-ring (not shown) is inserted into this groove 10c to ensure watertightness with the sprinkler retaining member 8.

[0267] like Figure 11 As shown, a passage with a rectangular cross section is formed to penetrate in the longitudinal direction inside the fluid element 10. The passage is formed into a water supply passage 12a, a vortex passage 12b, and a flow straightening passage 12c in order from the upstream side.

[0268] The water supply passage 12 a is a straight passage having a rectangular cross section with a constant cross-sectional area, extending from the inlet 10 d on the back side of the fluid element 10 .

[0269] Vortex passage 12b is a rectangular cross-section passageway provided downstream of water supply passage 12a, connected to water supply passage 12a (without a step). Specifically, the downstream end of water supply passage 12a and the upstream end of vortex passage 12b have the same dimensions and shape. The opposing walls (side walls) of vortex passage 12b are tapered so that the flow path cross-sectional area decreases downstream throughout vortex passage 12b. In other words, vortex passage 12b is tapered and gradually narrows in width toward the downstream side.

[0270] The rectifying passage 12c is a rectangular passage located downstream, communicating with the vortex passage 12b. Its cross-sectional area is constant and linear. The hot and cold water contained in the vortexes guided by the vortex passage 12b are rectified by the rectifying passage 12c and then discharged from the water outlet 10a. The cross-sectional area of ​​the rectifying passage 12c is smaller than that of the downstream end of the vortex passage 12b. A step 14 is formed between the vortex passage 12b and the rectifying passage 12c. The surface of the step 14, i.e., the wall surface, faces a direction perpendicular to the central axis of the vortex passage 12b.

[0271] On the other hand, Figure 12 As shown, the walls (ceiling and floor) of the water supply passage 12a, vortex passage 12b, and rectifying passage 12c that face each other in the height direction are all arranged on the same plane. In other words, the heights of the water supply passage 12a, vortex passage 12b, and rectifying passage 12c are all the same and constant.

[0272] Next, a hot / cold water collision section 16 is formed at the downstream end of the water supply passage 12a (near the connection between the water supply passage 12a and the vortex passage 12b). This collision section 16 is configured to partially block the flow path cross-section of the water supply passage 12a. This collision section 16 is a triangular prism-shaped portion that extends to connect the vertically opposing walls of the water supply passage 12a (the ceiling and the floor). It is positioned as an island in the center of the width of the water supply passage 12a. The cross-section of the collision section 16 is formed into an isosceles triangle, with its hypotenuse perpendicular to the central axis of the water supply passage 12a. Furthermore, the vertex of the isosceles triangle is positioned toward the downstream side.

[0273] By providing the hot and cold water collision portion 16, a Karman vortex is generated on the downstream side thereof, and the hot and cold water sprayed from the water spout 10a vibrates back and forth. That is, the hot and cold water supplied from the water supply passage (not shown) of the support member 6 flows into the water supply passage 4a ( Figure 6 ) and flows into the inlet 10d of each fluid element 10 held by the sprinkler retaining member 8. The cold and hot water flowing into the water supply passage 12a from the inlet 10d of each fluid element 10 collides with the cold and hot water collision portion 16, which is configured to partially block the flow path. This forms a vortex train of alternating counter-rotating Karman vortices downstream of the cold and hot water collision portion 16. The Karman vortices formed by the cold and hot water collision portion 16 grow while being guided by the vortex train passage 12b, which tapers to a tapered shape at the front end, before reaching the rectifying passage 12c.

[0274] The cold and hot water flowing into the rectifying passage 12c on the downstream side of the vortex passage 12b is rectified here. The cold and hot water sprayed from the water outlet 10a through the rectifying passage 12c is bent based on the flow velocity distribution in the water outlet 10a. Figure 11 The direction of the spray changes as it moves up and down. That is, the part with high flow rate of hot and cold water is located at Figure 11 When the hot and cold water are located at the upper end of the water outlet 10a, the hot and cold water are sprayed downward. When the high-velocity portion is located at the lower end of the water outlet 10a, the hot and cold water are sprayed upward. As described above, Karman vortices are alternately generated on the downstream side of the hot and cold water collision portion 16, thereby generating a flow velocity distribution in the water outlet 10a and deflecting the jet flow. In addition, the position of the high-velocity portion reciprocates due to the movement of the vortex train, so the sprayed hot and cold water also moves in a roughly predetermined vibration plane (similar to the vibration plane). Figure 11 It vibrates back and forth in a sinusoidal wave (in a wave form) in a plane parallel to the paper surface.

[0275] Here, as Figure 6 As shown, in this embodiment, each fluid element 10 is mounted obliquely downward. Therefore, the hot and cold water ejected from the water outlet 10a of each fluid element 10 falls while expanding in a fan-like pattern within a generally predetermined vibration plane. Furthermore, in this embodiment, each fluid element 10 is mounted to the shower head body 4 with its vibration plane oriented tangentially (circumferentially) to the elliptical shower head body 4. This creates a cylindrical shower jet with an elliptical cross-section beneath the shower head body 4 as a whole, enveloping the head of a user standing beneath the shower head body 4.

[0276] Furthermore, in the ninth embodiment, the first flow path portion 110 and the second flow path portion 210 also have a common portion on the mixing valve 500 (hot and cold water mixing portion) side and branch through the branch portion 550 .

[0277] Branch 550 is as follows Figure 25 As shown, it can be arranged in the vicinity of the first water spraying part 100, such as Figure 26 As shown, it can also be arranged in the vicinity of the mixing valve 500.

[0278] (Function of the Ninth Embodiment)

[0279] Next, refer to Figure 13 The operation of the shower device 1 according to the ninth embodiment of the present invention will be described.

[0280] Figure 13 The figure schematically shows a user who is showering with shower water ejected from the shower head body 4 of the shower device 1 according to the ninth embodiment of the present invention.

[0281] As described above, the hot and cold water sprayed from the nozzle 18 (first spray part) provided in the shower head body 4 is sprayed in the form of water mist. On the other hand, the hot and cold water sprayed from the fluid element 10 (second spray part) provided in the shower head body 4 is sprayed in the form of waves while reciprocating in a sinusoidal wave. Figure 13 As shown, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 are spread out in a roughly fan-shaped manner while falling. In addition, as described above, each nozzle 18 and each fluid element 10 are installed in a manner that is inclined downward toward the center of the shower head body 4 ( Figure 6 ). Therefore, the water spray space S surrounded by the shower water from each nozzle 18 and each fluid element 10 becomes narrower toward the bottom.

[0282] Furthermore, each nozzle 18 and each fluid element 10 is arranged at predetermined intervals along the annular shower head body 4. Figure 13 As shown, in the area (near the shower head body 4) where the width of the hot and cold water sprayed from the nozzles 18 and fluid elements 10 is not fully expanded, gaps exist between the hot and cold water sprayed from the nozzles 18 and fluid elements 10. This allows air within the spray space S surrounded by the shower water from the nozzles 18 and fluid elements 10 to flow out of the spray space S through the gaps between the shower water jets. Furthermore, in this embodiment, the shower head body 4 is annular, allowing air within the spray space S to flow upward through the inside of the shower head body 4. Consequently, the heat of the hot and cold water sprayed into the spray space S is not retained, maintaining a comfortable temperature within the spray space S.

[0283] Meanwhile, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 expands horizontally as it falls, forming a flat, fan-shaped stream as a whole. The fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 merge at a predetermined distance L after falling. Furthermore, the flat, fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 are directed tangentially to the annular shower head body 4. Therefore, the fan-shaped streams of hot and cold water sprayed from each nozzle 18 and each fluid element 10 surround the user's head and body, forming a film of water around the user's body. Therefore, the portion of the water spray space S above the predetermined distance L below the shower head body 4, due to the gaps between the shower water jets, functions as a heat release space. Furthermore, the portion of the water spray space S below the predetermined distance L below the shower head body 4, due to the convergence of the hot and cold water sprayed from each nozzle 18 and each fluid element 10, forms a film of water surrounding the user's body, thus functioning as a heat retention space.

[0284] As described above, the hot and cold water ejected from each nozzle 18 and each fluid element 10, after falling a predetermined distance L, forms a water film covering the user's upper body while striking the user's body. Therefore, the user's body is fully warmed by the hot and cold water. Therefore, even when the temperature in the shower room 2 is low, the user does not feel cold, and the user can shower for a long time.

[0285] According to the shower device of the ninth embodiment of the present invention, the shower head body 4 is fixed to the side wall surface 2a, allowing the user to shower without having to manually hold the shower head body 4. Furthermore, the multiple water spraying units, namely the nozzles 18 and the fluid elements 10, are spaced apart from each other on the shower head body 4. This creates gaps between the hot and cold water sprayed from the fluid elements 10 near the shower head body 4, preventing heat from stagnating within the spray space S surrounded by the shower water. This prevents users from feeling stuffy or having difficulty breathing during long showers. Furthermore, the hot and cold water sprayed from the nozzles 18 and fluid elements 10 spreads as it falls, impinging on a large area of ​​the user's body standing under the shower head body 4. The impinging hot and cold water further spreads across the body surface, effectively enveloping the user. As a result, even in cold temperatures, the showering user is less likely to feel cold and can continue showering for extended periods.

[0286] In addition, according to the shower device of this embodiment, the hot and cold water sprayed from each nozzle 18 and each fluid element 10 merge with each other at a position where they fall a predetermined distance L from each nozzle 18 and each fluid element 10 ( Figure 13 ), thus ensuring ventilation inside and outside the shower water space S surrounded by the shower water until the point where the hot and cold water merge, and thus preventing heat from stagnating. Furthermore, below the point where the hot and cold water merge, the user's body can be fully enveloped by the hot and cold water, thus being sufficiently warmed.

[0287] Furthermore, according to the shower device of this embodiment, the water spray space S surrounded by the sprayed hot and cold water narrows downward, thereby ensuring sufficient ventilation in the upper portion of the water spray space S. On the other hand, the space becomes smaller in the lower portion of the water spray space S, making it easier to ensure heat retention within the space and allowing the user to be fully warmed.

[0288] Furthermore, according to the shower device of this embodiment, the shower head body 4 is formed in an annular shape, so that the air in the water spray space S surrounded by the shower water flows out through the inside of the shower head body 4, thereby preventing the heat from stagnating in the water spray space S surrounded by the shower water.

[0289] In addition, according to the shower device of this embodiment, the length of the second flow path portion 210 from the mixing valve 500 (cold and hot water mixing portion) to each fluid element 10 is longer than the length of the first flow path portion 110 from the mixing valve 500 (cold and hot water mixing portion) to each nozzle 18. Therefore, even if a high temperature setting is erroneously performed, the temperature of the sprayed water with large particle size from each fluid element 10 can be expected to be reduced, thereby reducing the risk of scalding to the user (in addition to the heat conduction (heat dissipation) effect of the longer second flow path portion 210 itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion 210 can also be expected).

[0290] (10th embodiment)

[0291] Next, refer to Figure 14 A shower device according to a tenth embodiment of the present invention will be described.

[0292] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 9. Therefore, only the differences between the tenth embodiment and the ninth embodiment of the present invention will be described here, and the description of the same structures, functions, and effects will be omitted. Figure 14 The following is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the tenth embodiment of the present invention.

[0293] like Figure 14 As shown, the shower head body 20 of the shower device involved in the tenth embodiment of the present invention is configured in a rectangular ring shape. A plurality of sprinklers are provided along the shower head body 20 configured in the ring shape, forming a shower water jet that surrounds the user's head. The hot and cold water sprayed from each sprinkler is configured to expand into a flat fan shape while falling. In addition, each shower water jet expanded into a fan shape is directed in a direction parallel to each side of the shower head body 20, and merges with each other at a position a predetermined distance below each sprinkler, forming a water film around the user's body. Furthermore, each sprinkler is installed obliquely downward in such a manner that each shower water jet is directed toward the center of the shower head body 20, and the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, as a plurality of sprinklers provided on the shower head body 20, it is possible to adopt a plurality of sprinklers by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0294] In addition, according to the shower device of this embodiment, the length of the second flow path portion 210 from the mixing valve 500 (cold and hot water mixing portion) to each fluid element 10 is also longer than the length of the first flow path portion 110 from the mixing valve 500 (cold and hot water mixing portion) to each nozzle 18. Therefore, even if a high temperature setting is erroneously performed, the temperature of the sprayed water with large particle size from each fluid element 10 can be expected to be reduced, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion 210 itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion 210 can also be expected).

[0295] (11th embodiment)

[0296] Next, refer to Figure 15 A shower device according to an eleventh embodiment of the present invention will be described.

[0297] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 9. Therefore, only the differences between the 11th embodiment of the present invention and the 9th embodiment will be described here, and the description of the same structure, function, and effect will be omitted. Figure 15 This is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the eleventh embodiment of the present invention.

[0298] like Figure 15 As shown, the shower head body 30 of the shower device according to the eleventh embodiment of the present invention is composed of two linear shower head bodies 30a and 30b. Multiple sprinklers are arranged along each linear shower head body 30a and 30b, forming a shower spray that surrounds the user's head. The hot and cold water sprayed from each sprinkler is configured to fall while expanding into a flattened fan-shaped pattern. Furthermore, the sprinklers arranged in the center of each shower head body 30a and 30b spray a fan-shaped shower spray parallel to the direction in which the shower head body 30a and 30b extends. In contrast, the sprinklers arranged near the ends of each shower head body 30a and 30b spray a fan-shaped shower spray at approximately right angles to the direction in which the shower head body 30a and 30b extends.

[0299] Furthermore, the sprinklers provided on each shower head main body 30a, 30b spray hot and cold water diagonally downward in a direction in which the shower water sprayed approaches each other. Therefore, the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, the shower water sprayed from each sprinkler provided near the end of the shower head main body 30a and 30b is directed to merge with each other at a position where it falls a predetermined distance. Therefore, the shower water sprayed from the two shower head main bodies 30a, 30b configured in a straight line will surround the head of the user standing between the two shower head main bodies 30a, 30b. In addition, as a plurality of sprinklers provided on the shower head main body 30, it is possible to adopt a plurality of sprinklers provided on the shower head main body 30 by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0300] In addition, according to the shower device of this embodiment, the length of the second flow path portion 210 from the mixing valve 500 (cold and hot water mixing portion) to each fluid element 10 is also longer than the length of the first flow path portion 110 from the mixing valve 500 (cold and hot water mixing portion) to each nozzle 18. Therefore, even if a high temperature setting is erroneously performed, the temperature of the sprayed water with large particle size from each fluid element 10 can be expected to be reduced, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion 210 itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion 210 can also be expected).

[0301] (12th embodiment)

[0302] Next, refer to Figure 16 A shower device according to a twelfth embodiment of the present invention will be described.

[0303] The shape of the shower head body of the shower device of this embodiment is different from that of the above-mentioned embodiment 9. Therefore, only the differences between the 12th embodiment of the present invention and the 9th embodiment will be described here, and the description of the same structure, function, and effect will be omitted. Figure 16 This is a perspective view showing a state in which a user is showering and receiving shower water from the shower device according to the twelfth embodiment of the present invention.

[0304] like Figure 16As shown, the shower head body 40 of the shower device according to the twelfth embodiment of the present invention comprises two curved, extended shower head bodies 40a and 40b. These shower head bodies 40a and 40b curve and extend so that their ends approach each other. Multiple sprinklers are provided along the shower head bodies 40a and 40b. This creates a shower spray that surrounds the user's head. The hot and cold water sprayed from each sprinkler falls while expanding into a flattened fan-shaped pattern. Furthermore, the sprinklers provided in the center of each shower head body 40a and 40b spray a fan-shaped shower spray that expands tangentially to the direction in which each shower head body 40a and 40b extends. In contrast, the sprinklers provided near the ends of each shower head body 40a and 40b spray a fan-shaped shower spray at an angle approximately perpendicular to the direction in which each shower head body 40a and 40b extends.

[0305] Furthermore, the sprinklers provided on each shower head main body 40a, 40b spray hot and cold water diagonally downward in a direction in which the shower water sprayed approaches each other. Therefore, the water spray space surrounded by the sprayed hot and cold water is configured to narrow downward. In addition, the shower water sprayed from each sprinkler provided near the end of the shower head main body 40a and 40b is directed to merge with each other at a position where it falls a predetermined distance. Therefore, the shower water sprayed from the two curved shower head main bodies 40a, 40b will surround the head of the user standing between the two shower head main bodies 40a, 40b. In addition, as a plurality of sprinklers provided on the shower head main body 40, it is possible to adopt a plurality of sprinklers provided on the shower head main body 40 by appropriate configuration. Figure 7 The nozzle and Figure 11 The fluid element shown in FIG.

[0306] In addition, according to the shower device of this embodiment, the length of the second flow path portion 210 from the mixing valve 500 (cold and hot water mixing portion) to each fluid element 10 is also longer than the length of the first flow path portion 110 from the mixing valve 500 (cold and hot water mixing portion) to each nozzle 18. Therefore, even if a high temperature setting is erroneously performed, the temperature of the sprayed water with large particle size from each fluid element 10 can be expected to be reduced, thereby reducing the risk of scalding to the user (on the basis of the heat conduction (heat dissipation) effect of the longer second flow path portion 210 itself, the temperature reduction achieved by the (low-temperature) residual hot water remaining in the longer second flow path portion 210 can also be expected).
