Bathtub interconnecting part 42 and bath water described later connection flow path portion 47 are configured in the bottom 2a and upper end 2c of bathtub 2 Between centre below height and position h1 height and position on.That is, bathtub interconnecting part 42 and bath water described later connection runner Portion 47 is configured on the height and position between the height and position h1 of centre and the bottom 2a of bathtub 2.Thus, even following make With state, i.e. be stored in bath water example in bathtub 2 as described above among height and position h1 or so or ratio among height position Put the lower pondages of h1 stored, bather carry out half bath use state, bathtub interconnecting part 42 and bath water connection Flow path portion 47 is also full of by hot water, so as to make the hot water of bathtub using jet pump assembly 10 from water-discharge portion 6 to bather's Shoulder etc. spues.

As shown in Fig. 3 and Fig. 9 etc., jet pump assembly 10 is in the left and right directions of the side of water-discharge portion 6 of bathtub 2 is configured with The inboard (wall W sides) of bathtub connection oral area 12 is configured in the heart.Jet pump assembly 10 is with nozzle 44 and bathtub interconnecting part 42 Height and position turn into the modes of the lower positions of height and position h1 than centre and formed.In addition, jet pump assembly 10 is with bathtub Water introduction part 46 extends to the mode untill the position lower than the height and position h1 of centre near the upper end 2c of bathtub 2 Formed.In this way, being formed injection pump group in a manner of specially configuring nozzle 44 and bathtub interconnecting part 42 on lower position Part 10, the pondage of the hot water in bathtub 2 is less can also to be carried out from water-discharge portion 6 in the case where water storage water level is low Guttation.

In this way, jet pump assembly 10 is configured in the central bottom of the left and right directions of bathtub 2, and as shown in figure 13, can incite somebody to action Pump 4 is configured near the central more outward side side end of the left and right directions of the side of water-discharge portion 6 than being configured with bathtub 2. As shown in figure 14, pump 4 is configured in the bottom of the side side of bathtub 2 and the inner side of housing 20.In this way, pump 4 can be configured Side side of bathtub 2 etc., the hot water that pump upstream side runner 28 is flowed into from bathtub connection oral area 12 are directed into and are configured at bathtub 2 Side side pump 4, and from the hot water of the force feed of pump 4 then by pump downstream side runner 30 to the jet pump assembly 10 for being configured at center Or the injection water-discharge portion side runner 36 near center flows.

In the state of hot water is stored with, there is hot water hot water hotter among hot water to be easily moved upward, and The characteristic that cooler hot water easily moves downwards in hot water.Here, because bathtub interconnecting part 42 is configured in than bath On the higher position of cylinder connection oral area 12, therefore hot water hotter among hot water is easily higher to oral area 12 is connected than bathtub The bathtub interconnecting part 42 of position moves, and the temperature of the hot water in bathtub interconnecting part 42 is not easy to cool off, so as to be easy to maintain Compare the temperature of hot hot water.

Nozzle 44 by bathtub interconnecting part 42 by and towards bath water introduction part 46 in a manner of spray hot water so as to draw Hair injection pumping action.Nozzle 44 is formed as, and makes the diameter of its internal runner than the ejection section side runner of the upstream side of nozzle 44 32 diameter reduces.Thus, further speeded up by the hot water of the force feed of pump 4 in nozzle 44, as high speed hot water current from Nozzle 44 sprays.Nozzle 44 is directed towards bathtub interconnecting part 42 and bath water introduction part 46.Thus, nozzle 44 can be towards bath The internal spray of cylinder interconnecting part 42 and bath water introduction part 46 has the jet flow of the high speed of linear directional.From the outlet of nozzle 44 Be open injection high speed jet flow because introduce bathtub interconnecting part 42 in hot water and its flow gradually increase and flow velocity gradually decrease.

Due to spraying the nozzle 44 that hot water is reduced from flow diameter and being flowed into bath water by bathtub interconnecting part 42 and lead Enter portion 46, therefore jet pump assembly 10 has the pressure loss of regulation value.Can make the pressure loss value turn into From injection 16 discharge hot water of water-discharge portion when the pressure loss value value relatively, by making by jet pump assembly 10 Flow passage resistance force of waterproof and flow passage resistance force of waterproof untill water-discharge portion 16 is sprayed relatively, can be while making hot water in the runner of both sides Flow simultaneously while adjusting flow and flow velocity.

As shown in figure 5, air induction port portion 45 is configured in the front side (downstream of nozzle 44 in the guttation direction of nozzle 44 Side).Air induction port portion 45 is configured near the downstream of nozzle 44, and is formed with the bathtub sprayed from nozzle 44 The injection pumping action of water is introduced air into the bath water of injection.Air induction port portion 45 is formed with from bathtub interconnecting part 42 The air that the outside mode risen untill being through to the inside of bathtub interconnecting part 42 is installed and extended into bathtub interconnecting part 42 imports Oral area 45.Inner flow passage of the air induction port portion 45 formed with circular tube shaped, is introduced air into the inner flow passage.

Air induction port portion 45 is configured on the injection direction (being in the present embodiment above-below direction) of nozzle 44 Between nozzle 44 and the inlet portion 46a of the bath water introduction part 46 extended from bathtub interconnecting part 42 towards water-discharge portion 6.It is more specific and Speech, compared with forming the intermediate point between the top 44a and inlet portion 46a of exit opening of nozzle 44, air induction port portion 45 By closer to configuration in the side of nozzle 44.Further according to other sayings, air induction port portion 45 be with air induction port portion 45 with The top 44a of the nozzle 44 distance mode more shorter than the distance in air induction port portion 45 and inlet portion 46a is configured.Such as This, the inlet portion 46a that air induction port portion 45 is configured in than bath water introduction part 46 on the injection direction of nozzle 44 is more leaned on In region near the top 44a of the high nozzle 44 of the flow velocity of upstream side and the bath water sprayed from nozzle 44.

In addition, compared with the intermediate point between the top 44a and inlet portion 46a of nozzle 44, air induction port portion 45 also may be used With closer to configuration in inlet portion 46a sides.In this case, although due to being connected from the jet flow that nozzle 44 sprays because introducing bathtub Hot water in portion 42 and its flow increases, but with flow increase and flow velocity is reduced, therefore can will be from air induction port portion 45 air capacities importeding into hot water suppress than relatively low import volume.

Air induction port portion 45 (is in the present embodiment right and left in the transverse direction of the injection direction relative to nozzle 44 To) on, extended to from the side side of nozzle 44 nozzle 44 injection direction front nearby untill.More specifically, air Import oral area 45 be formed as, relative to bathtub interconnecting part 42 be provided with the bottom surface 42a of nozzle 44 for from side 42c to transverse direction Extension, and extend to the exit opening of nozzle 44 extended area C nearby untill.Extended area C is as making going out for nozzle 44 Mouthful opening towards downstream straight line extends when imaginary area it is defined to carry out.Prolong from the 42c of side in air induction port portion 45 Untill extending near the front of the injection direction of nozzle 44.In bathtub interconnecting part 42, air induction port portion 45 in side 42c and Extend between the central axis of nozzle 44.Thus, air induction port portion 45 is prolonged in a manner of being orthogonal to nozzle 44 from the 42c of side Untill the front front for extending nozzle 44.In this way, air induction port portion 45 is in the transverse direction of the injection direction relative to nozzle 44, The area extended to than side 42c near the front of the high injection direction of flow velocity of the bath water sprayed more in the inner part and from nozzle 44 Untill domain.

The top end opening portion 45a on the top in air induction port portion 45 is configured in the front on the top than nozzle 44 more to side On the position that face 42c sides are slightly closer to.The top end opening portion 45a is formed as following openings, i.e. side (bath water downstream The side of introduction part 46) opening portion become the inclined opening bigger than the opening portion of upstream side (side of nozzle 44).Because such as arrow The hot water of the high speed from nozzle 44 shown in head F4, and have and spray negative pressure caused by pumping action, air is from air The top end opening portion 45a for importing oral area 45 is introduced into (absorption), so as to be mixed into the air of fine (small) among hot water Bubble.

Air leading-in conduit 56 is connected with air induction port portion 45, sky can be carried out by being provided with air leading-in conduit 56 The air of the opening and closing on the importing road of gas imports switching valve 58.In the other end of air leading-in conduit 56 formed with being sucked out of bathroom The air openings (not shown) of air.In the present embodiment, because air spraying the negative pressure of pumping action because being drawn into heat In water, therefore the device of the air pump for air to be passed out to air leading-in conduit 56 etc. can be omitted.Air imports switching valve The control of 58 opening and closing is come electronic progress by control unit 8.That is, can be cut by the opening and closing of air importing switching valve 58 Ventilate the execution and stopping (ON/OFF) of supply.User H can be by the case where performing air and supplying, mixing air Enter the guttation to such as shoulder hot water of the guttation from the water-discharge portion 6 being arranged near the upper end of bathtub 2, to make guttation and bather Guttation during collision stimulates (the shock sense of guttation) to become soft.In addition, user H can stop or suspend air supply In the case of be mixed into air, stimulate (the shock sense of guttation) to strengthen guttation when guttation and bather are bumped against.So The amount for the small air bubble being imported into from air induction port portion 45 in hot water is controlled by control unit 8.Alternatively, it is also possible to form To omit air and importing switching valve 58 and import air naturally.And it is possible to using the pulsation mode of control unit 8, by certainly Regular or other conditions are moved mutually to switch the ON/OFF that air imports switching valve 58, are made from the sky in the guttation of water-discharge portion 6 The mixed volume of gas automatically changes, and the stimulation for making guttation be brought to user H will pass through defined condition changes.Such as Using such pulsation mode, it can more strengthen guttation effect of stimulation, the massage effect of shoulder hot water.Alternatively, it is also possible to structure Turn into, direct the air into oral area 45 and air imports the air intake system omission of the grade of switching valve 58 without making bathtub arrangement 1 mixed Enter fine air.

Bath water introduction part 46 forms at least a portion of bath water guiding in channel 34.From bathtub interconnecting part 42 towards telling The bath water introduction part 46 that water portion 6 extends forms the linearly extended runner on the extended line of the opening direction of nozzle 44.Bathtub Water introduction part 46 forms above bathtub interconnecting part 42 runner of linearly extended circular tube shaped upward.With the runner of nozzle 44 Diameter is compared, and the flow diameter of bath water introduction part 46 is larger formed.Thus, the cross section of fluid channel area phase with nozzle 44 Than the cross section of fluid channel area of bath water introduction part 46 is also larger formed.Thus, bath water introduction part 46, which forms, to be compared The flow of the hot water sprayed from nozzle 44 imports the size of the hot water of more various flow.Nozzle 44, bathtub interconnecting part 42 and bath water Introduction part 46 forms the runner of the straight line to the extension of direction, so as to along the jet flow side for the high speed sprayed from nozzle 44 To and form the current of high speed.

In addition, bath water guiding in channel 34 is at an upper portion thereof formed with the expanding unit 48 deployed in the lateral direction, it is thus possible to Spue the hot water deployed in the lateral direction in expanding unit 48 from water-discharge portion 6 to laterally (such as transverse direction close to level).Exhibition Open the runner that portion 48 up becomes larger formed with cross section of fluid channel area.The downstream of bath water guiding in channel 34 and water-discharge portion 6 connections.

Next, reference picture 10 connects flow path portion 47, pump upstream side runner 28 and aperture to Figure 12 to bath water adjusts machine Structure 54 etc. illustrates.

Figure 10 is the sectional view for the bathtub observed along Fig. 2 III-III lines, and Figure 11 is an implementation for representing the present invention The schematic sectional view of following states of the jet pump assembly of the bathtub arrangement of mode, i.e. set near connection flow channel entry point portion It is equipped with aperture adjustment mechanism and aperture adjustment mechanism is adjusted to open to the open mode in connection flow channel entry point portion, Figure 12 is to represent The schematic sectional view of following states of the jet pump assembly of the bathtub arrangement of an embodiment of the invention, i.e. aperture adjusts Mechanism in a manner of covering the part in connection flow channel entry point portion to set and aperture adjustment mechanism be adjusted into covering connection runner The closed mode of a part for inlet portion.

Bath water connection flow path portion 47 possesses connection runner 26, the formation bathtub 2 between bathtub interconnecting part 42 and bathtub 2 The connection flow channel entry point portion 50 of its intake section of side.Due to being provided with bath water connection flow path portion 47, therefore can be by bathtub 2 Bath water from bath water connection flow path portion 47 imported into jet pump water reservoir 41, without being provided in addition to jet pump The jet pump water reservoir 41 of component 10 supplies special watering of hot water etc., and bathtub arrangement 1 is formed so as to simplification Overall structure.Further, since the injection to jet pump assembly 10 that is externally supplied by hot water from bathtub 2 it is not provided in addition Special watering of pump water reservoir 41 etc., therefore by jet pump assembly 10, told even in from water-discharge portion 6 into bathtub 2 In the case of going out the flow greater flow than the bath water to spue from injection water-discharge portion 16, it can also prevent from chasing after because being connected to from outside The water supply added, and water level, i.e. water increase in bathtub 2.

Connection flow channel entry point portion 50 is formed in a manner of being connected with entrance channel 24, and is opened in entrance channel 24.Even Passage flow duct inlet portion 50 towards the interior zone A of entrance channel 24 and bathtub 2 (the balneation region of bather) in a manner of being open Formed.As shown in Figure 10, from the interior zone A of bathtub 2 to from (inboard of entrance channel 24) is carried out in entrance channel 24 When, longitudinal wall in the entrance channel in inboard and entrance channel 24 is more leaning on than bathtub connection oral area 12 in connection flow channel entry point portion 50 The opening of circle is formed at 24a top.The area of section of the runner in connection flow channel entry point portion 50 is to become than bath water introduction part The mode that the area of section of 46 runner is bigger is formed.

Here, connect flow channel entry point portion 50 and the bath water in bathtub 2 is drawn to the pump of the pump upstream side runner 28 of pump 4 Flow channel entry point portion 52 is independently formed.Inboard and entrance channel is more leaning on than bathtub connection oral area 12 in pump flow channel entry point portion 52 The opening of circle is formed at longitudinal wall 24a bottom in entrance channel in 24.Connection flow channel entry point portion 50 is formed than pump flow channel entry point The circular open of the larger radius of portion 52.Thus, the cross section of fluid channel area in connection flow channel entry point portion 50 is formed as than pump flow channel entry point The cross section of fluid channel area in portion 52 is bigger.In entrance channel on longitudinal wall 24a, connection flow channel entry point portion 50 and pump flow channel entry point portion 52 Between left by longitudinal wall 24a in entrance channel on predetermined distance, so as to connect flow channel entry point portion 50 and pump flow channel entry point Portion 52 is independently configured.Pump flow channel entry point portion 52 is formed in a manner of being connected with entrance channel 24, and is opened on entrance stream In road 24.Pump flow channel entry point portion 52 with towards the interior zone A of entrance channel 24 and bathtub 2 (the balneation region of bather) be open Mode formed.Because connection flow channel entry point portion 50 and pump flow channel entry point portion 52 are concurrently towards identical direction opening, therefore Concurrently flowed into towards respective importing oral area towards the current of the hot water of respective importing oral area, so as to make the water of inflow Stream is not easy to interfere or influenceed.

As shown in Figure 10, entrance channel 24 is formed as, and has cross section of fluid channel area and pump than connection flow channel entry point portion 50 The bigger cross section of fluid channel area of the summation (total) of the cross section of fluid channel area in flow channel entry point portion 52.Due to entrance channel 24 have than The summation (total) for connecting the cross section of fluid channel area in flow channel entry point portion 50 and the cross section of fluid channel area in pump flow channel entry point portion 52 is bigger Cross section of fluid channel area, therefore be respectively facing connection runner from the hot water that is flowed into entrance channel 24 of bathtub connection oral area 12 Concurrently flowed into towards respective importing oral area when inlet portion 50 and pump flow channel entry point portion 52, it is thus possible to current is not easy phase Mutually interference, and can prevent from flow channel entry point portion 50 is connected towards the hot water of the inflow of bathtub interconnecting part 42 because of the pump stream to pump 4 The attraction of the side of road inlet portion 52 and be affected, be stably supplied to jet pump assembly 10 so as to the hot water for the amount of it will be assumed.

As shown in Figure 10, entrance channel 24 has been internally formed connection flow channel entry point portion 50 and pump flow channel entry point portion 52 at it, And connect oral area 12 formed with bathtub as the single opening portion of the side of bathtub 2.Thus, carried out in bather from the side of bathtub 2 In the case of observation, only it can be seen that single bathtub connection oral area 12.In this way, due to can only form 1 bathtub connection oral area 12 i.e. entrance channel 24, without with directly formation connects flow channel entry point portion 50 and pump flow channel entry point portion on the longitudinal wall 2b of bathtub 2 52 2 openings, therefore the processing operation for entrance channel 24 to be connected with bathtub 2 can be reduced, and because bathing reduction Hermetic unit between cylinder 2 and entrance channel 24 is reduced, and can reduce the manufacturing operation of sealing and the management operation of sealing and Can reduce the risk of leak.

As shown in FIG. 11 and 12, jet pump assembly 10 is also equipped with adjusting the connection stream of bath water connection flow path portion 47 The aperture adjustment mechanism 54 of the aperture area of road inlet portion 50.Aperture adjustment mechanism 54 is arranged on connection flow channel entry point portion 50 Near.Aperture adjustment mechanism 54 possesses the baffle mechanism for the aperture area that can adjust connection flow channel entry point portion 50.Aperture adjusts Mechanism 54 can manually adjust the runner in connection flow channel entry point portion 50 with the user of bathtub arrangement 1 out of bathtub 2 The mode of aperture area is formed.More specifically, can be connected by the shirtsleeve operation of user H finger etc. from bathtub The side of oral area 12 is to manually change the position of aperture adjustment mechanism 54.In addition, the adjustment of the aperture area in connection flow channel entry point portion 50 It can also be carried out by electronic mechanism.

As shown in figure 11, it is adjusted to open the state of the open mode in connection flow channel entry point portion 50 in aperture adjustment mechanism 54 In the case of, the water formed with the hot water flowed from entrance channel 24 by connection flow channel entry point portion 50 towards bathtub interconnecting part 42 Flow F21, the current F22 of the hot water flowed from entrance channel 24 by pump flow channel entry point portion 52 to flow pumps 4.Because aperture adjusts Mechanism 54 is in the open mode for reducing connection flow channel entry point portion 50, therefore towards bathtub interconnecting part 42 formed with connecting The current F21 of the corresponding flow of the bore in flow channel entry point portion 50 and/or flow velocity.

As shown in figure 12, it is positioned over connecting all or part of pass in flow channel entry point portion 50 in aperture adjustment mechanism 54 In the case of closed state, because the flow and/or flow velocity that are flowed into the hot water for connecting flow channel entry point portion 50 are restricted, therefore to The flow of hot water that bathtub interconnecting part 42 supplies is restricted, even if without the control of pump 4, also can simply be adjusted from telling Flow, speed and flow of water of hot water that water portion 6 spues etc..Now, formed with from entrance channel 24 by connection flow channel entry point portion 50 flow towards the current F23 of the hot water of the flowing of bathtub interconnecting part 42, from entrance channel 24 by pump flow channel entry point portion 52 to pump 4 Hot water current F24.Here, because aperture adjustment mechanism 54 is in the closed mode for reducing connection flow channel entry point portion 50, Therefore the flow and/or flow velocity for the hot water for flowing into connection flow channel entry point portion 50 are restricted, and F23 flow and/or flow velocity become Flow and/or flow velocity than F21 is smaller.On the other hand, because current F23 and F24 flow and flow velocity are relative with the performance of pump 4 Should, therefore it is substantially certain.

Although in the present embodiment, aperture adjustment mechanism 54 can adjust beating for connection flow channel entry point portion 50 with 2 grades Open state, closed mode, but aperture adjustment mechanism 54 can also such as by 3 grades, 5 grades multiple grades adjust Connect the aperture (the opening and closing ratio of opening) in flow channel entry point portion 50.

According to the aperture adjustment mechanism 54 of present embodiment, in bathtub arrangement 1, the bathtub arrangement 1 can be with from spray It is higher and spued from water-discharge portion 6 to penetrate the flow velocity of bath water that the velocity ratio of the bath water of the discharge of water-discharge portion 16 spues from water-discharge portion 6 Bath water the bigger mode of flow of bath water that spues of flow-rate ratio injection water-discharge portion 16, from injection water-discharge portion 16 and guttation The bath water that portion 6 spues from the common supply of pump 4 simultaneously, can be simply altered or modified (micro- with fairly simple composition Adjustment) flow velocity and flow of the hot water that are spued from water-discharge portion 6, without carrying out with the hot water to be spued from injection water-discharge portion 16 The setting of the pump 4 of the change of flow velocity and flow and/or pump 4 change of itself.

Next, by Fig. 3 to Fig. 7, to the bathtub arrangement 1 of present embodiment only from the guttation of water-discharge portion 6 act into Row explanation.

Start bathtub arrangement 1 before the action of the guttation of water-discharge portion 6, user H is capable of balneation temperature hot water to Supply and stored untill such as water level WL0 in bathtub 2.Now, because bathtub 2 and bathtub interconnecting part 42 are via entrance stream Road 24 and connection runner 26 and connect, therefore formation the temperature roughly the same with bathtub 2 is stored with bathtub interconnecting part 42 The state of hot water.

When the guttation from water-discharge portion 6 for wanting beginning bathtub arrangement 1 acts, user H operates operating portion 38 to select From the guttation of water-discharge portion 6.The information that user H operates operating portion 38 is passed to control unit 8.Now, control unit 8 is based on pressure The value for the hydraulic pressure that force snesor 40 is detected carries out the judgement of the height of water level of the hot water in bathtub 2.

It is the predetermined water level that there are the possibility that air is imported from bathtub connection oral area 12 in the water level being judged as in bathtub 2 In the case of below WL2, control unit 8 is controlled in a manner of pump 4 is worked.The predetermined water level is, for example, bathtub connected entrance The water level WL2 of the height of the upper end in portion 12.Thus, it is to connect oral area than there are from bathtub in the water level being judged as in bathtub 2 In the case that 12 import predetermined water level (such as WL2) more high water level of the possibility of air, control unit 8 is so that the side that pump 4 works Formula is controlled.

When control unit 8 makes pump 4 work, then as indicated by arrows f1, pump 4 connects oral area 12 via entrance channel 24 from bathtub And pump upstream side runner 28 draws the hot water in bathtub 2.Then, as indicated by arrows f2, pump 4 is by the hot water being drawn to downstream side The force feed of pump downstream side runner 30.Control unit 8 controls switching valve 18, so as to selectivity opening and closing ejection section side runner 32 and injection The runner of both sides or any one party among water-discharge portion side runner 36.For example, without being moved from the guttation of injection water-discharge portion 16 Make and carry out in the case of the action of the guttation of water-discharge portion 6, making to tell to injection from pump downstream side runner 30 by switching valve 18 The connection of the runner of the side runner of water portion 16 turns into closed mode, and makes the stream from pump downstream side runner 30 to ejection section side runner 32 The connection in road turns into open mode.Now, as shown in arrow F3, hot water is fed into ejection section effluent from pump downstream side runner 30 Road 32.As shown in arrow F4, the hot water that passes through in the ejection section side runner 32 is from nozzle 44 towards bathtub interconnecting part 42 and bathtub The inner high speed of water introduction part 46 and point-blank spray.Now, in bathtub interconnecting part 42, from the hot water that nozzle 44 sprays because of spray The hot water penetrated pumping action and introduced in bathtub interconnecting part 42 to bath water introduction part 46 while flow.

Control unit 8 possesses the bath water for making to supply from pump 4 and performs the water-discharge portion described later only acted from the guttation of water-discharge portion 6 Guttation pattern.Control unit 8, which possesses, makes the bath water execution from the supply of pump 4 described later only from the guttation action for spraying water-discharge portion 16 Spray guttation pattern.

The velocity ratio of bath water that control unit 8 possesses the bath water that makes to supply from pump 4 to spue from the 1st water-discharge portion is from described The flow velocity for the bath water that 2nd water-discharge portion spues is higher and the flow-rate ratio of bath water that is spued from the 2nd water-discharge portion is from the described 1st The bigger mode of flow for the bath water that water-discharge portion spues perform it is described later from water-discharge portion 6 and injection water-discharge portion 16 simultaneously (same period) Guttation pattern while the guttation action of progress.In addition, control unit 8 can also possess by automatic and regular or other bars Part come mutually switch air import switching valve 58 ON/OFF pulsation mode.Thus, due to making from the guttation of water-discharge portion 6 The mixed volume of air changes, and can assign stimulation that guttation is brought to user H to change, therefore can more strengthen shoulder The guttation effect of stimulation of portion's hot water.Also, control unit 8 possesses to perform to be carried out from the guttation of water-discharge portion 6 and from spray simultaneously (same period) Penetrate the stirring guttation pattern of the guttation action of the guttation of water-discharge portion 16 (stirring water-discharge portion).According to stirring guttation pattern, Neng Gou The guttation carried out from the guttation of water-discharge portion 6 from injection water-discharge portion 16 is stirred to the hot water in bathtub 2, so as not to from telling The discharge temperature of water portion 6 is than relatively low hot water.

Next, as shown in Figures 5 and 6, to the hot water that is sprayed from nozzle 44 while introducing bath by spraying pumping action Hot water in cylinder interconnecting part 42 is while situation about being flowed to bath water introduction part 46 illustrates in more detail.

As shown in Figures 5 and 6, as shown in arrow F4, jet flow (injection stream) is formed from nozzle 44 with the hot water sprayed at a high speed, is being sprayed The openings of mouth 44 are upwardly formed at a high speed and have the current of powerful propulsive force.Now, the current of the hot water of the injection are because of injection Pumping action is injector effect and produces the effect of the hot water around introducing.In the present embodiment, as shown in arrow F5 and F6, Hot water in bathtub interconnecting part 42 is introduced into and (is expressed as being involved according to others) in the jet flow of the straight line as shown in arrow F4.This When, the flow q1 of the hot water of the flow q2 of the hot water introduced out of bathtub interconnecting part 42 with being sprayed from nozzle 44 is added, and is turned into The flow q3 (reference arrow F4 ') of hot water in the bath water introduction part 46 of greater flow.Such discharge relation can pass through q1+ Q2=q3 formula represents.In this way, using pumping action is sprayed, jet pump assembly 10 can realize following technologies, i.e. by nozzle Hot water in the bathtub interconnecting part 42 in 44 downstream is involved in make the technology of guttation flow amplification.

There is the hot water flowed into out of bathtub 2 because the hot water in bathtub interconnecting part 42, sprayed from nozzle 44 introduces, therefore In the case of the hot water (residual water etc. when last time uses) that low temperature is contaminated with the hot water sprayed from nozzle 44, also by In the hot water in bathtub interconnecting part 42 can be introduced while being supplied to water-discharge portion 6, therefore can be spued from water-discharge portion 6 and bathtub The hot water of the temperature of hot water in 2 relatively temperature.Thus, it is possible to more effectively suppress to make user H feel slight chill in the air, from 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 8, only being acted from the guttation of injection water-discharge portion 16 to the bathtub arrangement 1 of present embodiment Illustrate.

Wanting to start when only acting from the guttation of injection water-discharge portion 16 of bathtub arrangement 1, user H operation operating portions 38 To select the guttation from injection water-discharge portion 16.The information that user H operates operating portion 38 is passed to control unit 8.Now, control Portion 8 processed carries out the judgement of the height of water level of the hot water in bathtub 2 based on the hydraulic pressure value that pressure sensor 40 is detected.Judging In the case of for following water levels of water level WL3 that the water level in bathtub 2 is the height for spraying water-discharge portion 16, control unit 8 is not to make pump 4 The mode of work is controlled.Thus, it is than spraying the height more high water level of water-discharge portion 16 in the water level being judged as in bathtub 2 In the case of, control unit 8 is controlled in a manner of pump 4 is worked.

When control unit 8 makes pump 4 work, then pump 4 will draw hot water downstream side as shown in arrow F9 as shown in arrow F8 The force feed of pump downstream side runner 30.In order to carry out the guttation action from injection water-discharge portion 16 and moved from the guttation of water-discharge portion 6 Make, control unit 8 is controlled to switching valve 18, to make the runner from pump downstream side runner 30 to injection water-discharge portion side runner 36 Connection turn into open mode, and make from 30 connection to the runner of ejection section side runner 32 of side runner of pump downstream turn into close shape State.Now, as shown in arrow F10, hot water is fed into injection water-discharge portion side runner 36 from pump downstream side runner 30.Such as arrow Shown in F11, the hot water of injection water-discharge portion side runner 36 is flowed into from water-discharge portion 16 is sprayed towards bath cylinder injection.From injection guttation The hot water that portion 16 spues is by the hot water of the force feed of pump 4, and is formed compared with low discharge and the guttation stream of high speed.By with user H's Waist, back bump against, and the hot water to be spued from injection water-discharge portion 16 can carry out the massage for bumping against position.Therebetween, due to switching valve 18 Make to turn into closed mode from 30 connection to the runner of ejection section side runner 32 of side runner of pump downstream, therefore without from water-discharge portion 6 guttation action.

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.

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, by ejection section side runner 32 and bathtub Jet pump assembly 10 is set on water guiding in channel 34, due to that can make from being sprayed water-discharge portion side runner 36 to injection water-discharge portion 16 Untill runner the pressure loss and runner from ejection section side runner 32 and bath water guiding in channel 34 untill water-discharge portion 6 The pressure loss difference it is smaller, therefore can suppress significantly to be inclined to be supplied to injection by the hot water supplied from common pump 4 to tell Water portion side runner 36 and ejection section side runner 32 and bath water guiding in channel 34 either party, so as to from injection water-discharge portion The mode that the flow velocity for the hot water that the velocity ratio of 16 hot water to spue spues from water-discharge portion 6 is higher from water-discharge portion 6 and sprays water-discharge portion 16 hot water to spue simultaneously from the common supply of pump 4.

In addition, according to the bathtub arrangement 1 of an embodiment of the invention, flow path portion 47 can be connected from bath water to spray The hot water that pump water reservoir 41 imports bathtub 2 is penetrated, without being provided for the jet pump water storage to jet pump assembly 10 in addition Portion 41 supplies the special watering of hot water, so as to simplify the overall structure of bathtub arrangement 1.Further, since not in addition It is provided for hot water being supplied to the special watering of the jet pump water reservoir 41 of jet pump assembly 10 outside bathtub, therefore Even in by jet pump assembly 10, spued from water-discharge portion 6 into bathtub 2 than the flow of the hot water to be spued from injection water-discharge portion 16 In the case of bigger flow, the increase of water level in bathtub 2, i.e. water can be also prevented.

Also, according to the bathtub arrangement 1 of an embodiment of the invention, due to interior to connection flow channel entry point from bathtub 2 The current for the hot water that portion 50 flows into, the current of the hot water flowed into out of bathtub 2 to pump flow channel entry point portion 52 are relative to only respectively Vertical entrance and formed, therefore current can be made to be not easy to influence each other, so as to prevent from connection flow channel entry point portion 50 The hot water flowed into towards bathtub interconnecting part 42 is attracted to be influenceed by by pump 4 into pump flow channel entry point portion 52, and then can be to spray Penetrate pump group part 10 and hot water is stably supplied.

Also, according to the bathtub arrangement 1 of an embodiment of the invention, due to the cross section of fluid channel area of entrance channel 24 Be formed as, than connecting the summation of the cross section of fluid channel area in flow channel entry point portion 50 and the cross section of fluid channel area in pump flow channel entry point portion 52 more Greatly, thus in entrance channel 24 current of the hot water flowed into out of bathtub 2 to connection flow channel entry point portion 50 of branch, from bathtub The current of the hot water flowed into 2 to pump flow channel entry point portion 52 by more stable are formed in the state of independently, therefore energy Current are enough made to be not easy to influence each other.Thus, it is possible to be more prevented securely from towards bathtub interconnecting part 42 flow into hot water by The influence attracted by pump 4, so as to more stably supply hot water to jet pump assembly 10.

Further, since 1 entrance channel 24 can be only formed, without forming connection flow channel entry point portion 50 and pump in the side of bathtub 2 2 openings in flow channel entry point portion 52, therefore the processing operation for entrance channel 24 to be connected with bathtub 2 can be reduced, and Because reducing the hermetic unit between bathtub 2 and entrance channel 24, it is thus possible to reduce manufacturing operation and management operation and go back The risk of leak can be reduced.

Also, according to the bathtub arrangement 1 of an embodiment of the invention, can be to spue from injection water-discharge portion 16 The mode that the flow velocity for the hot water that the velocity ratio of hot water spues from water-discharge portion 6 is higher is told simultaneously from injection water-discharge portion 16 and water-discharge portion 6 Go out from the bathtub arrangement 1 of the hot water of the common supply of pump 4, can be by aperture adjustment mechanism 54, with fairly simple composition Agencies into come change from water-discharge portion 6 spue hot water flow velocity and flow, without carry out with from injection water-discharge portion 16 spue The pump setting and/or the change of pump itself of the change of the flow velocity and flow of hot water.

Also, according to the bathtub arrangement 1 of an embodiment of the invention, the hot water that will can be supplied from common pump 4, In a manner of the flow velocity for the hot water that the velocity ratio of the hot water from the injection discharge of water-discharge portion 16 spues from water-discharge portion 6 is higher, from configuration In the water-discharge portion 6 more closer to the top than injection water-discharge portion 16, spue and arrive the body of the user more closer to the top than injection water-discharge portion 16 Top such as neck, shoulder.
