And can be used after just the beginning to use of pump 4 from the guttation of water-discharge portion 6, and then can improve the startability of bathtub arrangement 1.
In addition, the flow q2 of the hot water introduced out of bathtub interconnecting part 42 is set as to the flow of the hot water than being sprayed from nozzle 44
The more flows of q1.In this way, due to q2>The relation of q1 flow, therefore mixed in the hot water sprayed from nozzle 44
Miscellaneous hot water (residual water of low temperature when last time uses, pump 4 etc. because of the time process after supplying hot water to bathtub 2 for having low temperature
Hot water of low temperature when the temperature of hot water in runner reduces etc.) in the case of, also due to the hot water sprayed is while draw
Enter the hot water in the flow q1 more various flow q2 of the hot water than being sprayed from nozzle 44 bathtub interconnecting part 42 while being supplied to water-discharge portion 6
Give, therefore in the hot water of bath water introduction part 46, the ratio of hotter hot water turns into leading, the hot hot water of the comparison with
The hot water temperature in hot water introduced from bathtub interconnecting part 42 approaches.Thus, it is possible to more effectively suppress to feel user H
Slight chill in the air, so as to be used after just the beginning to use of pump from the guttation of water-discharge portion 6, and then the starting of bathtub arrangement 1 can be made
Property improve.
The flow q3 of hot water in bath water introduction part 46 is for example set at the flow q1 of the hot water sprayed from nozzle 44
2 times~4 times of range of flow in.In addition, the flow q3 of the hot water for example in bath water introduction part 46 is set at 30L/min
In~80L/min range of flow.The flow q2 of the hot water introduced in from bathtub interconnecting part 42 is for example set at from nozzle 44
In the range of flow of 1 times of the flow q1 of the hot water of injection~3 times.
Imported as described above, the hot water sprayed from nozzle 44 introduces hot water in bathtub interconnecting part 42 and is flowed into bath water
Portion 46.The flow of water and flow velocity for the hot water that hot water in bath water introduction part 46 maintains to spray from nozzle 44 are while flow up
And reach expanding unit 48.The current of hot water form the current deployed in the lateral direction in expanding unit 48, and reach water-discharge portion 6.
As shown in arrow F7, the guttation mouth 22 that hot water from the lateral direction longer is formed is towards face side (bathtub private side) with waterfall
The mode of cloth spues.In this way, hot water is spued as the current of the banding with shoulder breadth or so width, than relatively evenly spilling
On user H neck and shoulder.The hot water to be spued from water-discharge portion 6 forms the flowing water of the substantially stabilization of one fixed width and thickness
Current.The hot water to be spued from water-discharge portion 6 can compare on the wider ranges such as user H neck, shoulder, chest and back
The mode being unrolled evenly flows, for example, be capable of warm half bath state user H body so as not to cooling off.
Further, since from water-discharge portion 6 spue hot water be to be supplied via jet pump assembly 10, therefore can be formed than with
The matching size of pump 4 can the flow that more increases of force feed flow.That is, relative to pump 4 can force feed flow, such as can realize
The guttation of the big flow from water-discharge portion 6 of 2 times~4 times sizes, without by the size-enlargement of pump 4.Setting position for pump
Put, size (size) there are the limitation in space, thus make the size-enlargement right and wrong of pump to realize the guttation of big flow
Often difficult.In addition, even if making the size-enlargement of pump to realize the guttation of big flow, also due to the vibration of pump, work
Sound becomes big, therefore there are the possibility that sense of discomfort is brought to user H.
On the other hand, in the present embodiment, can be by using injection in it can not easily make the environment of size-enlargement of pump
Pump group part 10 realizes the guttation of big flow.Bathed due to the guttation from the big flow of water-discharge portion 6 can be carried out, therefore even in being stored in
, also being capable of more efficiently warm user in the case that the amount hot water amount of immersion (user H) of hot water in cylinder 2 is fewer
H body is so as not to cool off.Further, since amount (the heat of user H immersions of hot water being stored in bathtub 2 can be made
Water) it is fewer, therefore water-saving result can be realized.Due to the guttation from the big flow of water-discharge portion 6 can be carried out, therefore can increase
The heating effect and massage effect of user H body, so as to increase user H relaxation effect and comfortable effect.

Next, as shown in figure 9, to same from water-discharge portion 6 and injection water-discharge portion 16 in the bathtub arrangement 1 of present embodiment
When (same period) carry out guttation action illustrate.
Fig. 9 is schematic sectional view, it is schematically indicated the bathtub arrangement of an embodiment of the invention is sitting in user
In the state of in bathtub, the internal structure for the bathtub arrangement observed along Fig. 2 III-III lines, and illustrate to carry out from telling
The situation for the guttation action that water portion and injection water-discharge portion are carried out simultaneously.
In addition, the guttation carried out simultaneously from water-discharge portion 6 and injection water-discharge portion 16 of the bathtub arrangement 1 for present embodiment
Action, on the bathtub arrangement 1 with embodiment only from the action of the guttation of water-discharge portion 6, only telling from injection water-discharge portion 16
Hydrodynamic(al) makees the explanation of common guttation action, and the description thereof will be omitted, and the part of main difference is illustrated.
Refer to from the guttation action that (same period) is carried out simultaneously of water-discharge portion 6 and injection water-discharge portion 16 in sometimes progress simultaneously from telling
Guttation when the guttation action of the progress of water portion 6, the guttation carried out from injection water-discharge portion 16 act acts.Thus, be not limited only to from
Guttation action that water-discharge portion 6 is carried out, the guttation action carried out since injection water-discharge portion 16 are also included from telling by the situation the same period
Guttation action that water portion 6 is carried out, the guttation action carried out since injection water-discharge portion 16 both sides when different respectively
The situation that guttation action is but carried out parallel.
When wanting to start the guttation action carried out from water-discharge portion 6 and injection water-discharge portion 16 of bathtub arrangement 1 simultaneously, use
Person H operation operating portions 38 carry out guttation of the two-way choice from the guttation of water-discharge portion 6 and from injection water-discharge portion 16.
As described above, it is than there are the possibility for connecting oral area 12 from bathtub and importing air in the water level being judged as in bathtub 2
Predetermined water level WL2 more high water level and the water level that is judged as in bathtub 2 be higher than spraying the water level WL3 of the height of water-discharge portion 16
During water level, control unit 8 in a manner of making the work of pump 4 to be controlled.
When control unit 8 makes pump 4 work, then as shown in arrow F12, pump 4 is via entrance channel 24 and pump upstream side runner
28 draw the hot water in bathtub 2 from bathtub connection oral area 12.Then, as shown in arrow F13, pump 4 is downward by the hot water being drawn to
Swim the force feed of pump downstream side runner 30 of side.Control unit 8 controls switching valve 18, to make ejection section side runner 32 and injection water-discharge portion
The both sides of side runner 36 turn into open mode.Thus, as shown in arrow F14 and F15, hot water is supplied to from pump downstream side runner 30
To ejection section side runner 32 and the both sides of injection water-discharge portion side runner 36.
The hot water passed through as shown in arrow F14 in ejection section side runner 32 is as shown in arrow F16 from nozzle 44 towards bath
The inner high speed of cylinder interconnecting part 42 and bath water introduction part 46 and point-blank spray.Now, in bathtub interconnecting part 42, from nozzle
The hot water of 44 injections are as shown in arrow F17 on one side by spraying the hot water in pumping action introducing bathtub interconnecting part 42 while to bathtub
Water introduction part 46 flows.Relative to the flow q1 of the hot water sprayed from nozzle 44, supplied from bath water introduction part 46 to water-discharge portion 6
Hot water flow q3 by amplification (reference arrow F16 ').As shown in arrow F18, hot water from the lateral direction longer is formed
Guttation mouth 22 spued towards face side (bathtub private side) in a manner of waterfall.
Due to the feelings of hot water (residual water etc. when last time uses) that low temperature is contaminated with the hot water sprayed from nozzle 44
Under condition, the hot water that can also introduce in bathtub interconnecting part 42 to water-discharge portion 6 while supply, therefore can be told from water-discharge portion 6
Go out the hot water of the temperature with the temperature of the hot water in bathtub 2 relatively.In addition, by using jet pump assembly 10, Neng Goucong
Water-discharge portion 6 carries out the guttation of big flow.
Next, to air is mixed into sprayed hot water by air induction port portion 45 in the present embodiment
Situation illustrates.
In Fig. 3 and Fig. 5, as shown in arrow F4, hot water is from nozzle 44 towards bathtub interconnecting part 42 and bath water introduction part 46
Inner high speed and point-blank spray.Now, in bathtub interconnecting part 42, from nozzle 44 spray hot water by spray pumping action and
The air introduced in air induction port portion 45 to bath water introduction part 46 while flow.Now, due to air induction port portion
45 are configured near the downstream of ejection section, therefore are introduced air into from the hot water that nozzle 44 sprays after just having sprayed
Into hot water.The flow of the current of the hot water sprayed from nozzle 44 is less amount of.Now, due to the hot water sprayed from nozzle 44
Current flow be in just sprayed after fewer state (flow of the hot water with being sprayed from nozzle 44 is roughly the same
Flow), therefore according to the flow of the hot water sprayed, can less suppress the import volume of air introduced.With than
Air induction port portion 45 is passed through in the bathtub interconnecting part 42 of side and bath water introduction part 46 farther downstream, the heat sprayed from nozzle 44
Water is while hot water by spraying pumping action to introduce in bathtub interconnecting part 42, and its flow is then while increase.In this way, due to flow
Amplification mainly than the side farther downstream of air induction port portion 45, therefore inhibit the water passed through near air induction port portion 45
The increase of the flow of stream, the flow of the air so as to suppress to introduce into hot water from air induction port portion 45 exceedingly increase
Greatly.
Also, the hot water due to being sprayed from nozzle 44 is while the hot water introduced by spraying pumping action in bathtub interconnecting part 42
Its flow is while increase, therefore the guttation of larger flow can be carried out in the state of the increase of air mixed volume is inhibited.Cause
And even in the feelings that the importing air into the current for the bath water that larger flow guttation is carried out from water-discharge portion is acted on by injector
It under condition, also can less suppress the import volume of air, cause so as to suppress the import volume increase of air from water-discharge portion
Guttation becomes to be easily broken off, and then can be formed than more uniform and stable guttation state.More specifically, can suppress in conduct
The wide cut of Rack and the current of film-form from the guttation mouth 22 for being rectangle the wide cut to be formed spue when, because being wrapped in guttation
Bubble containing larger size, and produce being broken of following current, disorderly, i.e. current are to be broken and be divided into multiple current
Mode gets muddled, current one-sided or one in the membranaceous current of uniform wide-thin in a manner of a part is interrupted
Occur being broken, being disorderly for the current such as space on point in a manner of current get muddled, thus air has been mixed into guttation
In the state of, it can also form the membranaceous smooth current of uniform wide-thin.
According to such current, be not limited only to can to bring when the current for being mixed into air bump against with user relaxation effect, by
Rub effect, and may also suppress the guttation being mixed into when the current of micro air bubble bump against with user and stimulate and (brought to user
Sensation) get muddled, and may also suppress and dabble, so as to when as shoulder hot water, be brought to user effectively
Relaxation effect.
Further, since air induction port portion 45 be configured near the downstream of nozzle 44 and/or injection direction just
In front surface region near face, thus from nozzle 44 spray hot water in the higher region of the flow velocity after just having sprayed by sky
Gas is incorporated into hot water.Thus, come to introduce air, energy from air induction port portion 45 by using the higher current of the flow velocity of hot water
Enough suppress air to be imported into as larger bubble, and air is divided into fine bubble and is imported.In this way, by heat
The bubble of fine sizes is mixed into water, can suppress to be mixed into the bubble of large-size, the bubble of the large-size causes from telling
The guttation in water portion easily forms fracture.Further, since being little by little mixed into air on a small quantity with the state of micro air bubble, therefore inhibit
Substantial amounts of air is mixed into as larger bubble, so as to be mixed into the air of less amount of total amount.Thus, it is possible to it is mixed into
The bubble of small amount and micro situation, and can make not allowing easy fracture more from the guttation stream of water-discharge portion.
Here, the current of the hot water in entrance channel 24 are illustrated.Hot water is from bathtub 2 by bathtub connection oral area 12
And it is flowed into entrance channel 24.In entrance channel 24, the company of being flowed into out of bathtub 2 is formed relative to entrance independently
The current of the hot water of passage flow duct inlet portion 50, be flowed into out of bathtub 2 pump flow channel entry point portion 52 hot water current.Due to connection
The opening of flow channel entry point portion 50 and the difference of pump flow channel entry point portion 52 concurrently formed with the interior zone A towards bathtub 2, therefore point
The current for the hot water not flowed into connection flow channel entry point portion 50 and pump flow channel entry point portion 52 are formed independently and point-blank towards each
Opening flow into current.Thus, it is possible to 2 current are made to be not easy to influence each other, so as to prevent from connection flow channel entry point
Portion 50 is attracted to be influenceed by by pump 4 towards the hot water that bathtub interconnecting part 42 flows into pump flow channel entry point portion 52, and then can
Hot water is stably supplied to jet pump assembly 10.
Further, since entrance channel 24 is formed as, the cross section of fluid channel area of entrance channel 24 is with than connection flow channel entry point portion
The summation of 50 cross section of fluid channel area and the cross section of fluid channel area in pump flow channel entry point portion 52 is bigger, thus in entrance channel 24
In area of space, in entrance channel 24 current of the hot water that connection flow channel entry point portion 50 is flowed into out of bathtub 2 of branch, from
The current that the hot water in pump flow channel entry point portion 52 is flowed into bathtub 2 by more stable are formed in the state of independently, because
This can make current be not easy to influence each other.Entrance channel 24 has enough water flow spaces (water flow space), the current area
Domain can configure the water from the hot water for connecting flow channel entry point portion 50 in bathtub 2 to inflow in a manner of respective streamline will not intersect
Stream, be flowed into out of bathtub 2 pump flow channel entry point portion 52 hot water current, and them can be made to be not susceptible to what is influenceed respectively
Independently flowed under degree.The current of the hot water attracted by pump flow channel entry point portion 52 are as from the interior zone A of bathtub 2 towards pump
The current of the hot water in flow channel entry point portion 52 and formed, and to suppress from the side of connection flow channel entry point portion 50 towards pump flow channel entry point portion 52
Hot water current mode and formed.Thus, it is possible to the hot water towards the inflow of bathtub interconnecting part 42 is prevented securely from by quilt
The influence that pump 4 attracts, so as to which hot water is more stably supplied to jet pump assembly 10.
The hot water that injection water-discharge portion side runner 36 is flowed into as shown in arrow F15 is told as shown in arrow F19 and F20 from injection
Water portion 16 towards bath cylinder injection.The hot water to be spued from injection water-discharge portion 16 be by the hot water of the force feed of pump 4, formed compared with low discharge and
The guttation stream of high speed.Bumped against by the waist with user H, back, the hot water to be spued from injection water-discharge portion 16 can be bumped against
The massage at position.
In fig.9, the stirring water-discharge portion being stirred to injection water-discharge portion 16 as the bath water to being stored in bathtub 2
And the situation for playing function illustrates.It can be carried out simultaneously together with the guttation from water-discharge portion 6 from the injection (stirring of water-discharge portion 16
Water-discharge portion) guttation stir the hot water in bathtub 2.In addition to the convection current of the natural hot water in bathtub 2, from injection water-discharge portion
16 hot water to spue at a high speed forms powerful current as shown in arrow F20, and the hot water in bathtub 2 is forced so as to be formed
Property stirring current.In addition, when being bumped against from injection water-discharge portion 16 with the hot water to spue at a high speed with user H, also produce for example
The current vertically deployed shown in arrow F25, so as to form the water that mandatory stirring is carried out to the hot water in bathtub 2
Stream.
Due to bathtub interconnecting part 42 and bath water connection flow path portion 47 be configured in bathtub 2 bottom 2a and upper end 2c it
Between below medium height position h1 height and position on, therefore in the case of it there are following possibilities, i.e. bathtub
The relatively low hot water of the temperature that is easily stored on lower position among hot water in 2 is flowed into the possibility of bathtub interconnecting part 42,
Also the bath water in bathtub 2 can be stirred using water-discharge portion 16 is sprayed, so that the hot water for making temperature higher is flowed into jet pump
Component 10., can be more effectively by while from the guttation of water-discharge portion 6, also carrying out the guttation from injection water-discharge portion 16
Suppress from jet pump assembly 10 to the relatively low hot water of the supplying temperature of water-discharge portion 6, cause from water-discharge portion 6 to user's H discharge temperature
Relatively low hot water.
Further, since injection water-discharge portion 16 is configured in the bathtub 2 for the connection runner 26 for being connected with bath water connection flow path portion 47
Longitudinal wall 2b on, and spray water-discharge portion 16 and oral area 12 is connected with bathtub relatively configured along identical longitudinal wall 2b, because
This can more efficiently stir what is flowed into the connection runner 26 of bath water connection flow path portion 47 by spraying water-discharge portion 16
Hot water.Thus, it is possible to more effectively suppress from jet pump assembly 10 to the relatively low hot water of the supplying temperature of water-discharge portion 6, cause from
Water-discharge portion 6 is to the relatively low hot water of user's H discharge temperature.
In the present embodiment, relative to larger guttation mouth 22 of the water-discharge portion 6 formed with wide cut and low speed and big is carried out
The guttation of flow, and spray water-discharge portion 16 and then form the opening of minor diameter and carry out the guttation of high speed and low discharge.Such stream
Fast and different flow guttation is carried out in the same period.In the present embodiment, due to that can make to be installed on ejection section side runner 32
The difference of the pressure loss of nozzle 44 and the pressure loss for the injection water-discharge portion 16 for being installed on injection water-discharge portion side runner 36 is smaller,
Therefore in the case of hot water is supplied from common pump 4, the flow that can also suppress hot water is significantly partial to each runner
Any one, so as to from water-discharge portion 6 and injection water-discharge portion 16 simultaneously carry out guttation action.In addition, by using injection pump group
Part 10, (when not being increased), also can in the case that the flow of the hot water supplied from pump to ejection section side runner 32 is certain
The guttation of enough big flows being increased from water-discharge portion 6, so as to be carried out in water-discharge portion 6 and the injection upper same period of water-discharge portion 16
Flow velocity and the respectively different guttation of flow.
According to the bathtub arrangement 1 of above-mentioned an embodiment of the invention, jet pump assembly 10 sprays from nozzle 44
Bath water while using the bath water for spraying pumping action and introducing in bathtub interconnecting part 42 while being supplied to water-discharge portion 6.Thus,
During due to the guttation since water-discharge portion 6, even if assuming to there are in runner between pump 4 and water-discharge portion 6 cooler
Residual water when last time uses, the hotter hot water that its one side can be also stored in bathtub 2 with this are mixed up while being supplied to
Water-discharge portion, therefore the sensation for making user H feel cold water can be suppressed.Thus, it is possible to pump 4 just begin to use after realize from
The usage of the guttation of water-discharge portion 6, so as to improve the startability of bathtub arrangement 1, and then the usage of bathtub arrangement 1 can be made
The free degree improve.
Further, since the special runner that need not form mandatory discharge residual water is formed, not produce residual water completely,
And also without the residual water discharge mode set from other water-discharge portions progress guttation etc., so as in the guttation from water-discharge portion
During beginning, the residual water in runner that will not directly be spued to the body of user when since the guttation of water-discharge portion, therefore energy
The free degree of guttation control when enough the free degree of raising runner design and guttation start.
Also, due to that, come the hot water that spues, therefore can make to tell in the case where inhibiting the size of pump 4 via jet pump assembly 10
Water-carrying capacity increases.Thus, it due to inhibiting the maximization of pump 4, therefore can improve the free degree of the configuration of pump 4, and energy
The problem of enough noises for reducing the maximization with pump 4, vibration.
In addition, according to the bathtub arrangement 1 of an embodiment of the invention, due to even in the bathtub sprayed from nozzle 44
In the case of the hot water that low temperature is contaminated with water, the hot water sprayed also can be while introduce the stream of the hot water than being sprayed from nozzle 44
The hot water in the bath water interconnecting part 42 of more various flow is measured while being supplied to water-discharge portion 6, therefore in the hot water to be spued from water-discharge portion 6
In, the ratio of the hot water hot from the comparison close with the temperature of hot water in bathtub 2 of the introducing of bath water interconnecting part 42 turns into leading.
Thus, it is possible to more effectively suppress to make user H feel slight chill in the air, and can be from use after just the beginning to use of pump 4 from guttation
The guttation in portion 6, so as to improve the startability of bathtub arrangement 1.
Also, according to the bathtub arrangement 1 of an embodiment of the invention, it can be formed shortlyer from being formed at bathtub 2
Longitudinal wall 2b bathtub connection oral area 12 rise untill the bathtub interconnecting part 42 for being configured at region near longitudinal wall 2b dorsal part
The length of runner, the temperature drop for the hot water that the temperature for being stored in the hot water of bathtub interconnecting part 42 is not easy out of bathtub 2 can be made
Low, the temperature that the temperature of the hot water so as to make to spue from water-discharge portion 6 is not easy the hot water out of bathtub 2 reduces.
Also, according to the bathtub arrangement 1 of an embodiment of the invention, because bathtub interconnecting part 42 is configured in than bath
On the higher position of cylinder connection oral area 12, therefore it is easy to the hot hot water of comparison to the bathtub that 12 higher position of oral area is connected than bathtub
Interconnecting part 42 moves, so as to make the temperature of the hot water in bathtub interconnecting part 42 be not easy to cool off, and due to bathtub being connected
Port portion 12 is configured on the position lower than bathtub interconnecting part 42, can be easy to prevent air from flowing from bathtub connection oral area 12
Enter, so as to prevent from making the temperature of the hot water in bathtub interconnecting part 42 cool off because air is flowed into bathtub interconnecting part 42,
It can thus be easy to make to maintain the hot temperature of comparison from the bath water that water-discharge portion 6 spues.
Also, according to the bathtub arrangement 1 of an embodiment of the invention, in the present invention so formed, due to
Water level in bathtub 2 is the situation for below the predetermined water level WL2 that there are the possibility that air is imported from bathtub connection oral area 12
Under, control unit 8 is controlled in a manner of pump 4 is worked, therefore can prevent air from being flowed into from bathtub connection oral area 12, and
It can prevent from causing the temperature of the hot water in bathtub interconnecting part 42 to cool off because air is flowed into bathtub interconnecting part 42, so as to
It is enough to be more prevented securely from the cooler water that spued from water-discharge portion 6.
