Description

  The present invention relates to a hot water supply apparatus, and more particularly to a hot water supply apparatus in which any one of a plurality of types of hot water supply modes including a mist mode can be selected by switching a switching means.

  Conventionally, a shower device which is a shower device provided with a plurality of types of water discharge ports is known (see, for example, Patent Document 1). This shower apparatus is as shown in FIG. 10, and an arm 43 having a plurality of shower spouts 2a, which are shower spouts 42, is provided vertically on both sides of a storage unit 41 having a mirror 40 installed at the front center. The storage unit 41 is installed so as to rotate laterally via a rotating shaft, a storage shelf 45 is installed on one side of the storage unit 41, a normal hand shower 46 is installed on the other side, and the storage unit 41 is further installed. A counter equipped with a faucet having a washout spout 47 is installed below, and a foldable basin table 48 for placing a washbasin is installed below the washout spout 47. When the user sits down and takes a shower bath, he sits in a chair placed in front of the storage unit 41 and takes a shower in a state where the basin 48 is turned down. In addition, when performing a bathing operation using a basin such as a basin, the basin stand 48 is raised, and a basin is placed thereon to perform the bathing operation. Further, when using a normal hand shower 46, the shower head of the hand shower 46 is held in the hand to perform a shower bath or the like.

  FIG. 11 is a piping block diagram of the conventional example, in which 50 is a water supply pipe for supplying water, 51 is a hot water supply pipe for supplying hot water, 52 is water and hot water from the water supply pipe 50 and hot water supply pipe 51. In the conventional example of FIG. 11, the hot water mixed by the thermo valve 52 is supplied to the shower outlet 42 through the water stop valve 54, and the thermo valve is provided. Hot water mixed with the valve 52 is supplied to the switching valve 55 side through another path, and can be selectively switched and supplied to the hand shower water outlet 56 and the washroom water outlet 47 of the hand shower 46 via the switching valve 55. It has become.

  However, the shower device shown in Patent Document 1 is limited to sitting and showering from the shower spout 42, showering by the hand shower 46, and hot water supply from the wash basin 47 to the wash basin 48. It was.

  Therefore, recently, a shower device has been developed which can obtain a sauna effect in the bathroom by spraying hot water in the bathroom in a mist form. This is a mist sauna bath in the bathroom by spraying a small amount of water from the mist nozzle in the form of a mist. The shower mode and mist are based on a start command by an artificially operated switch. The mode is switched.

By the way, in the shower bath, since the hot water sprayed from the shower nozzle has a large particle size, most of the thermal energy can be given to the human body, and the thermal effect can be obtained early. On the other hand, in a mist sauna bath, the hot water sprayed from the mist nozzle has a small particle size, so a part of its thermal energy is released into the bathroom space, and relative to the human body surface while warming the surrounding air. It is characterized by slowly giving a thermal effect. For this reason, for example, when switching from the shower mode to the mist mode, the mist operation is performed at the same temperature as the hot water temperature at the time of the shower operation. Instead of chilling and promoting sweating, it can be uncomfortable. In particular, when the user switches to the mist mode after taking a hot shower in the winter and switching to the mist mode, the user may first experience an unexpected high temperature mist. For this reason, controlling the mist temperature to an appropriate temperature is extremely important for a comfortable mist sauna bath.

One of the water outlets 2 (in the embodiment shown in the figure, five water supply outlets for shower 2a, water outlet 2b for washing place, water outlet 2c for hand shower, water outlet 2d for massage, and water outlet 2e for mist) You can choose to supply hot water.

  As shown in FIGS. 3 and 4, a hot water supply pipe 19 for supplying hot water and a water supply pipe 20 for supplying water are connected in communication with the temperature control means 18, and a pipe 21 is provided downstream of the temperature control means 18. The flow rate control means 17 is connected in communication with the switching means 1, and the switching means 1 is connected in communication with the downstream side of the flow rate control means 17 via a pipe 22. On the downstream side of the switching means 1, a plurality of branch water channels 3 (in the embodiment shown in the accompanying drawings, a shower water channel 3a, a wash water branch water channel 3b, a hand shower water channel 3c, a massage water channel 3d, a mist branch) A water channel 3e) is connected in communication, and the plurality of types of water outlets 2 (shower water outlet 2a, washing ground water outlet 2b in the embodiment shown in the accompanying drawings, and hand shower) are connected to the ends of the branch water channels 3, respectively. A water outlet 2c, a massage water outlet 2d, and a mist outlet 2e) are provided.

  Here, the branch water channel 3a for shower is constituted by a pipe passing through the nozzle unit 8 and the nozzle arm 9, and a plurality of shower water outlets 2a provided in the nozzle unit 8 and the nozzle arm 9 communicate with each other. Yes.

  Further, most of the branch water channel 3c for hand shower is constituted by the aforementioned shower hose 5a.

  As shown in FIG. 5, the switching means 1 is mainly composed of a switching valve main body 23, a shaft unit 26, a handle 1 a, and a collar portion 31.

  The switching valve main body 23 is fixed to the seating means 14, and this switching valve main body 23 has a cylindrical shape, and is provided with an inlet 11 through which hot water flows in from one side of the flow rate control means 17 at one end. Along the axial direction, a plurality of branch water channels 3 (in the embodiment shown in the accompanying drawings, a hand shower branch water channel 3c, a wash water branch water channel 3b, a massage branch water channel 3d, a shower branch water channel 3a, and a mist branch water channel 3e) A plurality of outlets 25 communicating with each other (in the embodiment shown in the accompanying drawings, a hand shower outlet 25c, a washing outlet 25b, a massage outlet 25d, a shower outlet 25a, and a mist outlet 25e) are switching valves. The main body 23 is provided on the side surface portion in order in the axial direction.

  A shaft unit 26 having a bottomed cylindrical shape with one end opened and the other end closed is rotatably fitted in the switching valve body 23, and the shaft unit 26 has an opening at one end of the switching valve body 23. The inlet 11 communicates with the other end and is fixed to the handle 1a. The side surface portion of the bottomed cylindrical shaft unit 26 is displaced in the axial direction and the circumferential direction by a plurality of water outlets 27 (in the embodiment shown in the accompanying drawings, for the hand shower toward one rotational direction of the shaft unit 26). A water outlet 27c, a washing water outlet 27b, a massage water outlet 27d, a shower water outlet 27a, and a mist water outlet 27e) are provided in this order.

  A release button 28 is provided on the handle 1a of the switching means 1, and a collar portion 31 (FIG. 5) containing a main stopper 29 and a sub stopper 30 shown in FIG. . The collar portion 31 is fixed to the switching valve body 23. The handle 1a and the collar portion 31 are provided with a display (not shown) indicating the water discharge position.

  As shown in FIG. 6, the release button 28 provided on the handle 1 a is provided with a contact portion 28 a and a guide portion 28 b, and the rotation of the handle 1 a is prevented when the contact portion 28 a hits the main stopper 29. The release button 28 can be pushed by a finger toward the center of the handle 1a and can be moved within a certain range. Further, the release button 28 is projected by the spring material 32 to the outer surface side of the handle 1a. Energizing power is given.

  The sub stopper 30 has a substantially triangular shape having an inclined surface 30a and a stopper surface 30b provided within the rotation range of the handle 1a. When the handle 1a is rotated in one direction, a release button attached to the handle 1a. The guide portion 28b of the 28 moves along the inclined surface 30a of the sub stopper 30 so that the handle 1a can be moved while pulling the release button 28 toward the center of the handle 1a. After moving over the inclined surface 30a, the contact portion 28a of the release button 28 is the stopper surface of the sub-stopper 30 even if the handle 1a is rotated in the reverse direction after moving over the inclined surface 30a. In this case, when the release button 28 is pushed in, the contact portion 28a becomes the stopper surface. Since moved inward to a position not opposed to 0b, it is possible to contact portions 28a rotates the handle 1a in the reverse direction in this state is rotated in the reverse direction through the sub-stopper 30.

  The main stopper 29 has a configuration in which the contact portion 28a cannot get over even when the release button 28 is pushed in as much as possible. If the handle 1a is turned one section to the left from the "hand shower" position where the hand shower water outlet 27c and the hand shower outlet 25c shown in FIG. 6 communicate with each other, the washing water outlet 27b and the washing ground are provided. The “massage” position where the massage outlet 25b communicates with the massage outlet 25d and the massage outlet 25d is connected to the massage outlet 25d by turning one section to the left. Furthermore, if it is turned one section to the left, it becomes a “seat shower” position where the shower water outlet 27a and the shower outlet 25a communicate with each other, and if it is turned one section to the left, it gets over the auxiliary stopper 30. After that, the contact portion 28a of the release button 28 comes into contact with the left side surface of the main stopper 29 and stops, and this position is the mist water outlet 27e and the mist outlet 25e. There is "mist" position to communicate with each other.

  There is a secondary stopper 30 between the “seat shower” position and the “mist” position, but the counterclockwise rotation is counterclockwise as the guide portion 28b moves along the inclined surface 30a and gets over as described above. Can rotate without stopping at the sub stopper 30 portion.

  On the other hand, even if it rotates counterclockwise at the “mist” position, the counterclockwise rotation is prevented because the contact portion 28a faces the stopper surface 30b. However, by pushing the release button 28, the handle is 1a can be rotated counterclockwise.

  Thus, when any one of the “seat shower” position, “washing outlet” position, “massage” position, and “hand shower” position is selected by rotating the handle 1a, the handle of the temperature control means 18 is selected. The hot water temperature can be manually adjusted by operating 18a. At this time, the amount of hot water can be manually adjusted by the handle 17a.

  On the other hand, when the “mist” position is selected, the mist mode is set when the contact portion 28a shown in FIG. 6 hits the main stopper 29. At this time, a change-over switch (for example, a limit switch or the like) not shown is set. The signal is turned on, and the signal is sent to the specified temperature setting means 34g shown in FIG. In the specified temperature setting means 34g, the temperature of the hot water supplied to the mist nozzle is set to a preset specified temperature regardless of the temperature of the hot water in the other mode selected immediately before. The temperature control means 18 mixes the hot water supplied from the hot water supply pipe 19 and the water supplied from the water supply pipe 20 so as to obtain the specified temperature so as to obtain the specified temperature. As the specified temperature, for example, any temperature of 43 to 44 ° C. in summer and any temperature of 45 to 48 ° C. in winter are preferable. If it is desired to make the mist hotter or cooler while the mist at the specified temperature is being ejected, it may be finely adjusted by operating the handle 18a. Further, when the mist spray amount is desired to be increased or decreased further, the handle 17a may be finely adjusted. Whether it is summer or winter, for example, a dedicated season selection switch may be provided and manually switched to summer or winter by operating the switch, or a timer having a calendar function may be provided. , It may be switched automatically in summer or winter.

  Further, during the execution of another mode, for example, during the shower mode, the handle 1a can be rotated to switch to the mist mode. In this case as well, hot water in the shower mode can be obtained by the specified temperature setting means 34g. Regardless of the temperature, the mist can be ejected at a specified temperature set in advance to the hot water temperature supplied to the mist nozzle. As an example, when the other mode is the shower mode, the shower side electromagnetic valve 33a is closed and the mist side electromagnetic valve 33e is opened. At this time, because of the switching time of the electromagnetic valves 33a → 33e, switching is performed with a slight interval as shown in FIG. After the switching, the mist is ejected from the mist outlet 2e of the nozzle arm 9. Also at this time, the mist temperature is set so as to be the specified temperature preset by the specified temperature setting means 34g. Therefore, when the mode is switched to the mist mode, the mist can be automatically ejected at a temperature at which there is no unpleasant feeling after the shower bath. In particular, a mist with a constant temperature always spouts when switching to the mist mode after a shower bath with a high hot water temperature in the winter, or when switching to the mist mode after a shower bath with a low water temperature in the summer season. Therefore, the user is not surprised or uncomfortable, and as a result, a comfortable mist sauna bath can be performed. The other mode immediately before the mist mode is not limited to the shower mode, and may be any one of a hand shower mode, a washing area spout mode, and a massage mode.

  Note that, in a shower bath while sitting, since the hot water sprayed from the shower nozzle has a large particle size, most of the thermal energy can be given to the human body, and the nozzle arm 9 is supplied with hot water. Since a plurality of types of nozzles serving as hot water jetting means are provided at a plurality of positions at the tip of the head, for example, the nozzle arm 9 can be rotated forward and lowered so that a human body part below the neck can be showered at a time in a sitting position. In this way, a warming effect can be obtained at an early stage by bathing in hot water all over the body as if it were raining. Furthermore, when a shower nozzle is provided behind the waist of the sitting human body, the back can be effectively warmed in the sitting posture.

  On the other hand, in the mist sauna bath, since the hot water sprayed from the mist outlet 2e has a small particle size, a part of the thermal energy is released into the bathroom space and warms the surrounding air against the body surface of the human body. The heat effect can be given relatively slowly, which makes it possible to raise the set temperature of the mist above the shower temperature, and since the particle size is small, the whole body is wrapped in drizzle It creates a feel and warms it together with the ambient temperature of the human body, so it feels like having a bath like a steam sauna and is thought to have a sweating promoting effect.

  In the above embodiment, the case where the mist temperature is set higher than the shower temperature has been described. However, it is also effective to improve the comfort after bathing by cooling the body that has been hot watered by bathing with a low temperature mist. is there. In other words, rather than taking a bath while taking a shower bath, it is more effective to cool down once and then take a bath, so that continuous sweating and a feeling of heat can be suppressed after bathing. In the experiment, it was found that a temperature that is slightly lower than the body temperature in calm, about 36 ° C., is appropriate as a temperature suitable for cool-down. When the temperature is lowered to about 30 ° C., the temperature is too lower than the body temperature, too cold and uncomfortable, and the heart burden increases. In addition, it is preferable to immediately lower the temperature to 36 ° C., rather than slowly lowering the mist temperature. The reason is that the body is already hot with sweating, etc., so it was found that lowering the mist temperature slowly made it uncomfortable, and lowering it immediately was better for the body. Further, even if it is immediately lowered, the temperature is up to about 36 ° C., so there is no problem because the burden is not felt in the experience. Experiments have also shown that cooldown is preferable not only in summer but also in winter. FIG. 9 shows an example in the case of ejecting a cool-down low temperature mist. At this time, it is preferable to immediately lower the temperature to 36 ° C. rather than slowly lowering the mist temperature after the shower operation. The reason is that the body is already hot with sweating, etc., so it was found that lowering the mist temperature slowly made it uncomfortable, and lowering it immediately was better for the body. Further, even if it is immediately lowered, the temperature is up to about 36 ° C., so there is no problem because the burden is not felt in the experience. Experiments have also shown that cooldown is preferable not only in summer but also in winter.

  Next, an example of performing an automatic switching operation with the remote controller will be described.

  In this example, as shown in FIG. 7, a hot water supply pipe 19 for supplying hot water and a water supply pipe 20 for supplying water are connected to the temperature control means 18, and a pipe 21 is further provided downstream of the temperature control means 18. The flow rate control means 17 is connected in communication via a plurality of branch water channels 3 (in the embodiment shown in the accompanying drawings, the branch water channel for shower 3a and the branch for the washing place are connected to the downstream side of the flow rate control means 17 via a pipe 22). A water channel 3b, a branch water channel for hand shower 3c, a branch water channel for massage 3d, and a branch water channel for mist 3e) are connected to each other, and a shower water outlet 2a (FIG. 1) is provided at the end of each branch water channel 3, respectively. There are provided a plurality of types of water outlets 2, a water outlet 2 b (FIG. 2), a hand shower water outlet 2 c (FIG. 1), a massage water outlet 2 d (FIG. 1), and a mist outlet 2 e (FIG. 1). .

  Furthermore, a shower side electromagnetic valve 33a, a washing place electromagnetic valve 33b, a hand shower side electromagnetic valve 33c, a massage side electromagnetic valve 33d, and a mist side electromagnetic valve 33e are interposed in each of the branch water channels 3a to 3e, respectively. The electromagnetic valves 33a to 33e are controlled to be opened and closed by a control signal from the switching means 1. The switching means 1 includes a seat shower control circuit 34a, a washing area spout control circuit 34b, a hand shower control circuit 34c, a massage control circuit 34d, a mist control circuit 34e, and an automatic switching function from the shower mode to the mist mode. An automatic switching control circuit 34f and a specified temperature setting control circuit 34g are provided. The specified temperature setting control circuit 34g constitutes specified temperature setting means for increasing or decreasing the hot water temperature to the specified temperature when switching from the shower mode to the mist mode.

  A remote controller 6 is detachably hooked and locked to a hooking means (not shown) on the wall 7 of the bathroom. The remote control cord 6a is connected to the switching means 1 through a connection port (not shown) provided behind the seating means 14. As shown in FIG. 7, the remote controller 6 includes a massage switch 35d, a hand shower switch 35c, a washing area spout switch 35b, a seat shower switch 35a, a mist switch 35e, for sending signals to the control circuits 34a to 34g. An automatic changeover switch 35f, a temperature adjustment switch 35g, and a flow rate adjustment switch 35h are provided. By operating these switches 35a to 35h, the plurality of types of water discharge ports 2 (in the embodiment shown in FIG. 7, a shower water discharge port 2a, a washroom water discharge port 2b, a hand shower water discharge port 2c, and a massage water discharge port 2d). , One of the mist outlets 2e) can be selected to supply hot water.

  Here, when any one of the “massage switch 35d”, “hand shower switch 35c”, “washing outlet switch 35b” and “seat shower switch 35a” of the remote controller 6 is pressed, the temperature adjustment switch 35g is used. The hot water temperature can be adjusted. The temperature can be adjusted by the flow rate adjustment switch 35h.

  On the other hand, when the “mist switch 35e” of the remote controller 6 is pressed, the mist side electromagnetic valve 33e is opened, and mist is ejected from the mist outlet 2e of the nozzle arm 9. At this time, the temperature is preset by the specified temperature setting means 34g. Since the mist is ejected at the specified temperature, the same effect as in the manual embodiment (for example, a shower bath with a hot water temperature raised in winter, or a shower bath with a hot water temperature lowered in summer) Even after switching to the mist mode after performing the above, the effect of always ejecting mist at a constant temperature can be obtained. During the mist mode, the mist flow rate can be adjusted by the flow rate adjustment switch 35h.

  Further, when the “automatic switch 35f” of the remote controller 6 is pressed, the shower mode is first set, and the mode is automatically switched to the mist mode after a predetermined time has elapsed. First, the timer is activated, the seat shower control circuit 34a turns on the shower side electromagnetic valve 33a, and fine water flow from the shower spout 2b of the nozzle unit 8 and the nozzle arm 9 from the shoulder, waist, and hands of the human body. After a certain time has passed, a shower mode electromagnetic valve 33a is closed by a timer and switching means 1, and a mist side electromagnetic valve 33e is opened. At this time, the solenoid valve 33a → 33e is switched at a certain interval for the switching time. After the switching, the mist is ejected from the mist outlet 2e of the nozzle arm 9. At this time, since mist is ejected at the specified temperature preset by the specified temperature setting means 34g, the same effects as in the manual embodiment (for example, a hot water temperature is raised in winter to take a shower bath, or Even when the mist mode is switched to after a shower bath with the hot water temperature lowered in the summer, an effect that mist of a constant temperature is always ejected) can be obtained. The flow rate of the mist after switching the mist mode can be adjusted by the flow rate adjustment switch 35h. In this example, the switching from the shower mode to the mist mode is automated by the automatic switching function of the switching means 1, so that a high thermal effect is obtained in the first shower mode, and a steam sauna-like bathing feeling is obtained in the subsequent mist mode. As a result, the sweating action is promoted and the comfort after bathing can be enhanced. In addition, the effect characteristics of the human body obtained from the two types of nozzles can be fully exhibited without performing manual switching operation, and the automatic switching function of the switching means 1 has a plurality of branches. Since the water channel 3 is automatically switched, there is an effect that two different kinds of bathing environments can be easily and inexpensively created.

  The mist temperature when the "automatic switch 35f" is pressed is not a predetermined temperature (reference temperature) set in advance, but a temperature (relative to the shower temperature) based on temperature information from the temperature detection unit ( For example, it may be set to a temperature that is several degrees higher than the shower temperature or a temperature that is several degrees lower than the shower temperature.
