Fig. 1 is the circuit diagram that is used for the safety circuit of massaging pool of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, composition and the operation principle that is used for the safety circuit of massaging pool of the present utility model done more detailed explanation.
As shown in Figure 1; the safety circuit that is used for massaging pool of the present utility model; be connected with the control circuit board PCB of massaging pool; this circuit comprises the one first relay K M1 that normally closed interlock is parallel with one another; one second relay K M2 and one the 3rd relay K M3; mutual placed in-line temperature protection switch; heater strip and hydraulic pressure switch SB1; usually; temperature protection switch and heater strip are arranged in the heating tube; also comprise a unidirectional conduction device D; the normally closed interlock of the 3rd relay K M3; the normally open contact of this first relay K M1; this hydraulic pressure switch SB1; heater strip and temperature protection switch constitute first supply access, this unidirectional conduction device D; the normally open contact of the 3rd relay K M3; the normally open contact of this first relay K M1; this hydraulic pressure switch SB1; this heater strip and this temperature protection switch constitute second supply access.
Unidirectional conduction device D is preferably a diode, but also can be other unidirectional conduction devices such as bidirectional triode thyristor.
Further, unidirectional conduction device D is in series with an electric current electric fuse, for preventing that electric current from because of fortuitous event when excessive, guaranteeing the safety of entire circuit.Similarly, also be in series with an electric fuse on the path of the hydraulic pressure switch SB1 and the first relay K M1 normally open contact.
On the path at the normally open contact place of the second relay K M2, be in series with a massage pump M1 and a filter pump M2.
An alternative supply power supply is that above-mentioned first supply access and second supply access are powered, and the access way of power supply adopts conventional connected mode well known in the art, and this supply power supply typically adopts the alternating voltage of 110-120 volt; In addition, through after the transformation of transformator, this supply power supply provides Dc low voltage power supply for control circuit board PCB, for example, and 12 volts Dc low voltage power supply.
Control circuit board PCB adopts and the essentially identical design of existing massaging pool, and it is used to control the duty of massaging pool, for example, and startup, heating, massage etc.
Control circuit board PCB is connected with a control panel, this control panel as with the interface of this control circuit board, operate by user.Particularly, this circuit board is provided with control massage circuit and carries out adding hot key and controlling the massage key that the massage circuit carries out massage operation of heating operation, in addition, also is provided with display device, for example charactron, LCDs etc. on this circuit board.Be more convenient operation, also be provided with filter keys and temperature increasing-and-decreasing key ("+" and "-") on the control panel.
Particularly, each button on the control panel has following function:
The function of temperature key: click the temperature key, the shown numerical value of charactron begins flicker, and can adjust the setting of temperature this time, increases progressively by "+" numerical value, successively decreases by "-" numerical value.
The function that adds hot key: click and add hot key, burner on light on the control panel is bright, it is simultaneously also bright to filter display lamp, the first relay K M1 closure in the circuit, heater strip begins heating, and filter pump is also started working simultaneously, clicks to add hot key again, heating and filtration quit work simultaneously, and display lamp separately all goes out.
The function of massage key: click the massage key, the massage display lamp is bright, the second relay K M2 closure in the circuit, and massage pump M1 starts working.Click again the massage key then massage pump M1 quit work, the massage display lamp go out.
The function of filter keys: click filter keys, it is bright to filter display lamp, and filter pump M2 starts working.Click again filter keys then filter pump M2 quit work, filter display lamp and go out.
Below in conjunction with accompanying drawing and foregoing description, further specify the operation principle that is used for the safety circuit of massaging pool of the present utility model.
Press in the ban on the control panel add hot key the time, control circuit board PCB goes up little relay (figure does not show) closure of control heating, simultaneously, circuit board PCB goes up little relay (figure does not show) closure of controlled filter, filter pump is started working.First relay K M1 energising, the first relay K M1 normally open contact closure, hydraulic pressure switch SB1 is also closed, heater strip is by the normally closed interlock power supply of the 3rd relay K M3, the power of heating tube is total power 850W, electric current is about 7A, the electric current of entire product is no more than 12.5 peace A, at this moment, if press the massage key, control circuit board PBC goes up little relay (figure does not show) closure of control massage, the second relay K M2 and the 3rd relay K M3 energising, the normally open contact closure of the second relay K M2 and the 3rd relay K M3, massage pump M1 duty, the power supply of heating tube is simultaneously also switched to the normally open contact power supply of the 3rd relay K M3 by the normally closed interlock power supply of the 3rd original relay K M3.Because unidirectional conduction device D only allow voltage half pass through, therefore the power of heater strip reduces half, this moment, the power of heater strip was half-power 425W, and the electric current of heater strip is about 3.5A, it is 900W that massage pump M1 leads, and electric current is 7.5A, and the electric current of entire product also is no more than 12.5A, realized limit heating edge massage function, heat preservation effect in the time of can playing massage.
When pressing the massage key in the ban, the little relay closes of control massage on the circuit board, the second relay K M2 and the 3rd relay K M3 energising, the normally open contact closure of the second relay K M2 and the 3rd relay K M3, massage pump M1 work, the power supply of heating tube is simultaneously also switched to the normally open contact power supply of the 3rd relay K M3 by the normally closed interlock power supply of the 3rd original relay K M3, but if do not press when adding hot key, the little relay of control heating can not be closed on the circuit board, simultaneously, the little relay of controlled filter on the circuit board (figure does not show) can not be closed, filter pump M1 does not work, and the first relay K M1 is energising not, and the first relay K M1 normally open contact can not be closed, hydraulic pressure switch SB1 can not be closed, and heating tube can not be worked.At this moment, have only function of massage pump in work, and the power of massage pump is 900W, electric current is 7.5A, can not surpass 12.5A.
In sum, the safety circuit that is used for massaging pool of the present utility model can make the massage functions of massaging pool and heating function open simultaneously, and has guaranteed the safety of entire circuit in the case, satisfies the requirement of north America region to the household electrical appliances safe current.Because two kinds of functions are used simultaneously, can make the user when enjoying massage, keep water temperature not descend, therefore strengthened the comfortableness of massaging pool.
