Description

  The present invention relates to a jet bath control device, and more particularly to a control device that can reliably make a transition to a stop in each operation mode.

In general, a jet bath is provided with a suction port and a spout on the side wall of the bathtub, and the hot water in the bathtub sucked in from the suction port is spouted into the bathtub from the spout, and the amount of jets spouted from this spout, etc. Is configured to be a predetermined state (operation mode). Conventionally, as this operation mode, as disclosed in, for example, Patent Document 1, two steps of “strong” and “weak” have been proposed.
JP 2003-219773 A

  However, in such a jet bath, the operation mode is set to two stages of “strong” and “weak”, and as shown in FIG. 8, every time the operation switch is turned “ON”, “strong” “weak”. Since it is operated in the order of “stop”, for example, it is difficult to immediately shift from “strong” to “stop”, and the number of operation of the operation switch for shifting to “stop” is increased, thereby improving operability. But it is not preferable. In particular, in addition to the two-stage operation modes of “strong” and “weak”, there are additional operation modes such as the addition of operation modes that periodically change the strength of the jet or intermittently eject the jet. As it increases, it becomes more difficult to immediately shift to “stop”.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a jet bath control device capable of reliably shifting to a stopped state by a single operation of an operation switch. is there.

  In order to achieve such an object, the invention described in claim 1 of the present invention is configured to suck in hot water in the bathtub from a suction port provided in the bathtub and to draw a plurality of the sucked hot water into the bathtub from the outlet provided in the bathtub. The jet bath control device for jetting in the operation mode includes an operation switch capable of switching the operation mode, and when the operation switch is operated during operation in the predetermined operation mode in the plurality of operation modes. It shifts to a stop state, It is characterized by the above-mentioned.

According to a second aspect of the present invention, when the operation switch is not operated for a predetermined time during the operation in the predetermined operation mode , the operation mode returns to the first operation mode in the sequence . According to a third aspect of the present invention, the operation switch is an on / off switch disposed on an upper edge flange of the bathtub.

  According to the first aspect of the present invention, the operation switch that can switch the operation mode is operated during the operation of the predetermined operation mode in a plurality of operation modes such as “strong” and “weak”. When the operation switch is switched to the stop state, the operation switch can be switched directly from each operation mode to the stop state by, for example, a single ON operation, and the operation switch operation count for shifting to the stop state is minimized. As a result, the operability of the jet bath can be improved.

According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, when the operation switch is not operated for a predetermined time during the operation in the predetermined operation mode, the first operation of the sequence is performed. In order to return to the mode , when the operation switch has not been operated for a predetermined time, for example, the sequence can be reset to reliably return to the initial state or the like. Therefore, even when a plurality of operation modes such as “strong” and “weak” are provided, for example, the “strong” operation mode is set as an initial state in advance, and the operation switch is not operated continuously for a predetermined time. By operating the operation switch at intervals, it is possible to start and stop only the “strong” operation mode. For example, the same operation as in the case of providing the “strong” operation mode can be performed.

According to the invention described in claim 3 , in addition to the effect of the invention described in claim 1 or 2 , since the operation switch is an on / off switch arranged on the upper edge flange of the bathtub, Each operation mode and stop state can be set by operating the switch, and the operability of the jet bath can be improved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 3 show an embodiment of a jet bath employing a control device according to the present invention, FIG. 1 is a block diagram showing its basic configuration, FIG. 2 is a plan view of an operation switch, and FIG. It is a timing chart which shows an example.

  As shown in FIG. 1, the jet bath 1 includes a pump 2 whose number of rotations can be set in a plurality of stages, a control device 3 that controls the operation of the pump 2, a remote control that can be remotely operated, and the like. And the suction inlet of the said pump 2 and the suction inlet 6 provided in the bathtub 5 are connected via the suction side piping 8a, and the ejection outlet of the pump 2 and the ejection outlet 5b of the bathtub 5 are connected via the ejection side piping 8b. It is connected. At this time, the suction port 6 and the spout 7 are located on the back side wall 5a of the bathtub 5 in the back foot direction, for example, the suction port 6 is located on the bottom side of the bathtub 5, and the spout 7 is a predetermined dimension above the suction port 6. It is provided in the position.

  The control device 3 is composed of a microcomputer or the like, a controller 14 in which operating conditions of the pump 2 to be described later are stored in advance, a power supply circuit 10 connected to a commercial power supply, and a voltage of the power supply circuit 10 being varied to change the pump 2 The voltage variable circuit 11 and the like are supplied to An operation switch 13 attached to the upper edge flange 5 b of the bathtub 5 is connected to the controller 14 of the control device 3.

  For example, a push button type on / off switch is used as the operation switch 13, and as shown in FIG. 2, the switch panel 13 a is turned on (conductive state) when pressed with a finger, and is released by releasing the finger. An on / off button 13b that is turned off (non-conducting state) is provided, and a pair of indicator lamps 13c and 13d that includes LEDs that are turned on when an operation mode described later is “strong” or “weak” are provided. ing. When the ON / OFF button 13b of the operation switch 13 is pressed and turned on, a predetermined voltage (electric power) is supplied from the power supply circuit 10 of the control device 3 to the pump 2, and the pump 2 operates in a predetermined state. Or the pump 2 which is operating is stopped.

  Next, the operation of the jet bath 1 will be described based on the timing chart of FIG. As shown in FIG. 3, when a bather taking a bath in the bathtub 5 turns on the on / off button 13b of the operation switch 13 in the off state at a time t1, for example, for a predetermined time T1, the pump 2 is rotated at a high speed, for example. The strength of the jet that is rotated by a number and is ejected from the ejection port 7 into the bathtub 5 is set to “strong”. Note that the ON time T1 of the operation switch 13 is only required to make the contact point of the operation switch 13 conductive, and a relatively short time of, for example, 1 second or less is used.

  Then, when the “strong” operation mode has elapsed for a predetermined time T2 and the operation switch 13 is turned on again by the bather at time t2, the pump 2 is stopped and the ejection of the jet from the outlet 7 is stopped. . Further, when the operation switch 13 is turned on again at time t3 in this stopped state, the pump 2 rotates at a low rotational speed, for example, and the strength of the jet flow ejected into the bathtub 5 from the ejection port 7 is set to “weak”. Further, when the operation switch 13 is turned on at time t4 during the “weak” operation mode, the operation mode is set to the stop state.

  That is, in the case of this jet bath 1, every time the operation switch 13 is turned on, the pump 2 operates in the sequence of “strong” → “stop” → “weak” → “stop” and is ejected from the ejection port 7. The strength of the jet will be set to “Strong” → “Stop” → “Weak” → “Stop”, so that the operation mode can be switched and, for example, even when operating in the “strong” operation mode Therefore, it is possible to immediately shift to “stop” simply by turning on the operation switch 13.

  As described above, in the jet bath 1 of the above embodiment, when the operation switch 13 is operated during the operation in each of the “strong” and “weak” operation modes, the control device 3 before the operation modes are switched. Since the pump 2 is temporarily stopped by the control signal, it is possible to shift directly from each operation mode to the stop state by one ON operation of the operation switch 13, for example, even if the operation is "strong" 1 can be stopped, and an emergency stop or the like can be handled appropriately. At the same time, since there is a stop state between the “strong” and “weak” operation modes, and each operation mode is not performed continuously, when the bather receives a jet of each operation mode on the back, for example, The difference between “strong” and “weak” can be experienced with certainty, and for example, the massage effect can be further promoted.

  In addition, since the operation switch 13 is turned on only by turning on the operation switch 13 during operation in each operation mode, the operation switch 13 for stopping the operation of the jet bath 1 may be operated only once as a minimum. This eliminates the need to continuously press the operation switch a plurality of times as in the conventional jet bath, improving the operability and causing the malfunction of the jet bath 1 due to an operation error of the operation switch 13 that is likely to occur during continuous operation. For example, a comfortable whirlpool bathing is possible while reliably shifting to an operation mode according to preference.

Further, a push button on / off button 13 b is provided on the operation panel 13 a of the operation switch 13, and this operation switch 13 is disposed on the upper edge flange 5 b of the bathtub 5. The operation switch 13 can be easily operated to reliably set the desired operation mode, and the operation lamps 13 are provided with indicator lights 13c and 13d for displaying the operation modes. Thus, the bather can clearly recognize each driving state, and the jet bath 1 excellent in operability and convenience can be obtained. In addition, the operation of shifting to the stop state when the operation switch 13 is turned on during each operation mode can be dealt with by previously storing the sequence in the controller 14, so that the configuration of the jet bath 1 can be simplified and formed at low cost. At the same time, for example, an existing jet bath can be easily accommodated.

  The operation of the jet bath 1 according to the present invention is not limited to the above-described example, and includes operations such as those shown in FIGS. Hereinafter, the same parts as those in the above example will be described with the same reference numerals. First, the timing chart shown in FIG. 4 is characterized in that the operation mode has three stages of “strong”, “medium”, and “weak”, and every time the operation switch 13 is turned on, “strong” → “stop” → “medium”. → It is configured so that it can be operated in the sequence of “Stop” → “Weak” → “Stop”.

  Further, the timing chart shown in FIG. 5 is characterized in that the operation mode has four stages of “strong”, “wave”, “rhythm”, and “weak”, and every time the operation switch 13 is turned on, “strong” → “stop” → It is configured to be operable in the sequence of “Wave” → “Stop” → “Rhythm” → “Stop” → “Weak” → “Stop”. At this time, the operation mode “Wave” is an operation using a jet that gives a massage feeling that looks up, and the operation mode “Beat” is an operation using a touch jet that strikes the ton.

  In these timing charts, if the operation switch 13 is turned on during each operation mode, the operation state always shifts to the stop state. Therefore, the same effect as the above timing chart can be obtained, especially when there are many operation modes. It is possible to further improve the usability of the jet bath 1 by preventing the occurrence of a mistake in switching to each operation mode, which is likely to occur.

  Further, the timing chart shown in FIG. 6 is characterized in that, for example, the operation switch 13 is set for a predetermined time T3 (for example, T3 = 5 to 10 seconds) at the time of “medium” operation in three stages of “strong”, “medium”, and “weak”. If the on-operation is not performed, the sequence is reset to the initial state when the time T3 has elapsed. In the case of this example, if the operation switch 13 is turned on after the operation switch 13 is turned on to be in a stop state, the “weak” operation can be performed instead of the “weak” operation. Further, the state of returning after the predetermined time T3 is not limited to the initial state, and may return to an appropriate state, for example, automatically returning to the most frequently used operation mode recently used by the bather.

  Further, the timing chart shown in FIG. 7 is characterized in that, for example, when the operation switch 13 is pressed and held for a predetermined time T4 during the “weak” operation of the “strong”, “wave”, and “weak” operation modes, the operation mode is changed. For example, it is configured to shift from “weak” to the preset “wave” operation mode. By configuring in this way, the operation mode is set in the controller 14 in advance according to the preference of the bather, so that the user can select the desired operation mode by simply pressing and holding the operation switch 13 during any operation mode. The bath can be switched automatically to a comfortable bath bath, and the number of operations of the operation switch 13 to the desired operation mode can be reduced, so that the operability of the jet bath 1 can be further improved. .

  In the case of this example, as in the example shown in FIG. 6, the operation mode to be automatically shifted may be set in advance, for example, the bather may shift to the most frequently used operation mode recently. You can also. In the case of the example shown in FIGS. 6 and 7, the operation mode is not limited to the illustrated example, and may be three or four stages as shown in FIGS. 4 and 5, for example, “rhythm” or the like. Of course, other appropriate operation modes can be added.

  The present invention is not limited to each of the timing charts described above. For example, the reset function shown in FIG. 6 is added to each timing chart of FIGS. 3 to 5 or the long press shown in FIG. Functions can also be added. In addition, the configuration of the control device 3 and the arrangement position of the operation switch 13 in the above embodiment are examples, and for example, the remote controller 4 is omitted, or the operation switch 13 is arranged on a wall panel near the bathtub in the bathroom. The present invention can be changed as appropriate without departing from the scope of the invention.

  The present invention is not limited to a jet bath in which a suction port and a spout are provided on one side wall of a bathtub in the back foot direction, but the suction port and the spout are, for example, on both side walls in the back foot direction and side walls perpendicular to the back foot direction. The present invention can also be applied to a provided jet bath.
