DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which like reference numerals refer to like elements throughout.
1 is a block diagram illustrating a configuration in which a hot water temperature control device of the present invention is applied to a bidet; and FIG.
2 is a signal flow diagram illustrating the operation of the controller according to the hot water temperature control method of the present invention.

The following detailed description is merely an example, and is merely an example of the present invention. Further, the principles and concepts of the present invention are provided for the purpose of being most useful and readily explaining.

Accordingly, it is not intended to provide a more detailed structure than is necessary for a basic understanding of the present invention, but it should be understood by those skilled in the art that various forms that can be practiced in the present invention are illustrated in the drawings.

1 is a block diagram showing an example of a configuration of a hot water temperature control apparatus according to the present invention. 1, a hot water temperature control apparatus according to the present invention includes an inlet valve 102, an inlet temperature sensor 104, a flow rate sensor 106, a key signal input unit 108, a first heater 110 A second heater driving section 116, an outflow temperature sensor 118, a water outlet valve 120, and a control section 122. The first heater driving section 112, the second heater 114, the second heater driving section 116, .

The inlet valve 102 is connected to an external water conduit or the like capable of supplying water to be used as cleansing water, and may be configured to receive tap water or the like as cleansing water from the external water conduction or the like when it is opened.

The intake temperature sensor 104 can detect the temperature of water obtained through the intake valve 102.

The flow rate sensor 106 can detect the flow rate of water obtained through the inlet valve 102.

The key signal input unit 108 may include a plurality of function keys, and may input a predetermined operation command when the user selectively operates the plurality of function keys.

For example, the key signal input unit 108 may generate a command signal for instructing the set water outflow temperature and the set water outflow amount of the water that the user desires to go out by selectively operating the plurality of function keys. Further, the key signal input unit 108 can generate an outflow command signal for instructing the user to selectively operate the plurality of function keys to command the water out at the set outflow temperature and the set outflow rate. In addition, the key signal input unit 108 may generate various operation commands in addition to the above-described operation commands, as the user selectively operates the plurality of function keys.

The first heater 110 may be configured to primarily heat the water, which is received through the inlet valve 102, to a set reference temperature preset at 33 to 35 ° C, for example.

For example, the temperature of the water obtained from the outside water conduit to the bidet varies greatly depending on the season, but is usually about 4-5 DEG C in the winter when the outside temperature is low and about 15 DEG C in the hot summer. And the flow rate of the water obtained from the outside water conduction or the like into the bidet can be varied according to the setting of the user.

Therefore, in the present invention, it is possible to heat the water, which is obtained on the basis of the case where the temperature of the water received by the bidet from the external water conduction lamp is the lowest, and the flow rate of the water which is obtained by the user is set as the maximum, It is preferable to configure it to have a calorific value.

The first heater driving unit 112 applies heat to the first heater 110 to generate heat so that the first heater 110 can adjust the water received through the inlet valve 102 to a set reference temperature Allow it to be heated first.

The second heater 114 may be configured to be able to secondarily heat the water firstly heated to the set reference temperature by the first heater 110 to a set water outflow temperature required by the user.

For example, even if water supplied from an external water heater is firstly heated to the set reference temperature in the first heater 110, there is a difference of about +/- 50% between the temperature of the firstarily heated water and the predetermined set hot water temperature A temperature difference of about 2 to 3 占 폚 has occurred.

Therefore, according to the present invention, the second heater is heated by adjusting the calorific value of the second heater according to the temperature and flow rate of the water firstly heated by the first heater 110 and the set outgoing water temperature set by the user, So that the temperature can be precisely adjusted to the set water temperature required by the user.

The second heater driving unit 116 adjusts the heating power applied to the second heater 114 to adjust the heating temperature of the second heater 114, It is possible to constitute the second heater 114 to heat the water which is firstly heated to the temperature to the set water outflow temperature required by the second heater 114. [

The outflow temperature sensor 118 can be configured to detect the temperature of the water that is secondarily heated to the set outflow temperature by the second heater 114. [

The outflow valve 120 is connected to an outflow nozzle for letting out water secondarily heated by the second heater 114 and is precisely heated to a preset outflow temperature by the second heater 114 And water can be discharged through the outflow nozzle.

The control unit 122 controls the water inlet valve 102 so that water to be used as cleansing water is received from the outside and controls the water outlet valve 120 according to the set water flow rate It is possible to control so that the water at the set flow rate is allowed to flow out through the outflow nozzle.

The control unit 122 controls the first heater driving unit 112 in accordance with the temperature of the water detected by the intake temperature sensor 104, the flow rate of water detected by the flow sensor 106, So that the temperature of the water received through the inlet valve 102 can be firstly heated by the first heater 110 to the set reference temperature.

The control unit 122 controls the second heater driving unit 116 according to the temperature of the water detected by the outflow temperature sensor 118, the flow rate of the water detected by the flow sensor 106, So that the second heater 114 can precisely heat the first heated water at the set reference temperature from the first heater 110 to the set outgoing temperature precisely.

The operation of the hot water supply control apparatus of the present invention will be described in detail with reference to the drawing of FIG.

2 is a signal flow diagram illustrating the operation of the controller according to the hot water temperature control method of the present invention. Referring to FIG. 2, the control unit 122 determines whether an outgoing command is generated from the key signal input unit 108 (S200).

When an outflow command is generated from the key signal input unit 108, the control unit 122 opens the inlet valve 102 so that water to be used as cleansing water can be obtained from the outside (S202).

The control unit 122 determines the temperature of the water that is received through the inlet valve 102 as an output signal of the inlet temperature sensor 104 in step S204, (Step S206).

In this state, the controller 122 controls the first heater 110 (which can heat the water temperature of the first heater 110 to the set reference temperature) according to the determined water temperature and flow rate, (S208).

Here, the amount of heat generated by the first heater 110 may be determined by the controller 122 according to a preset formula, but the controller 122 may be burdened with a large amount of heat.

Therefore, according to the present invention, the amount of heat generated by the first heater 110 is stored in a memory (not shown) provided in the control unit 122 as a look-up table according to the temperature, flow rate, And the heating amount of the first heater 110 is determined by using the stored look-up table.

When the heating value of the first heater 110 is determined, the controller 122 controls the first heater driving unit 112 according to the determined heating value so that the temperature of the water that the first heater 110 generates and receives For example, the temperature can be set to a preset reference temperature set at 33 to 35 DEG C (S210).

Here, when heating the water to be obtained by determining the calorific value of the first heater 110 according to the temperature and flow rate of the water to be obtained and the set reference temperature, the temperature of the water to be obtained and the set reference temperature are different from each other The temperature difference between the actual temperature of the water heated by the first heater 110 and the set reference temperature may be large, for example, typically about 2 to 3 占 폚.

In this state, the controller 122 determines the temperature of water heated by the first heater 110 so as to approach the set reference temperature (S212), by the output signal of the outflow temperature sensor 118, And determines the set watering temperature (S214).

The control unit 122 controls the temperature of the water heated by the first heater 110 and the flow rate of the water determined by the output signal of the flow rate sensor 106 and the set outflow temperature set by the user The amount of heat generated by the second heater 114 is determined (S216).

The amount of heat generated by the second heater 114 is also controlled by the lookup table according to the temperature of the first heated water, the flow rate of the water received, and the set outgoing water temperature in the same manner as the first heater 110 (Not shown in the figure) provided in the first heater 114, and determines the amount of heat generated by the second heater 114 using the stored look-up table.

When the amount of heat generated by the second heater 114 is determined, the controller 122 controls the second heater driver 116 according to the determined amount of heat to heat the second heater 114 and heat the water secondarily (S218).

Here, in the present invention, the second heater 114 heats the water heated by the first heater 110 to the preset reference temperature of 33 to 35 DEG C to the set outflow temperature set by the user at 36 to 40 DEG C.

Therefore, the temperature of the water heated by the second heater 114 is low, so that the water can be heated with a very low temperature deviation from the set water outflow temperature set by the user.

In this state, the controller 122 determines whether or not the temperature of the water to be headed is heated to the set heading temperature (S220). When the temperature of the water to be headed is heated to the set heading temperature, (S222) so that the water heated to the set water outlet temperature is allowed to flow out (S222).

The control unit 122 continuously inputs the output signal of the water outlet temperature sensor 118 to determine the water outlet temperature of the water to be delivered (S224), and adjusts the heating value of the second heater 114 according to the determined water outlet temperature (S226).

That is, the controller 122 determines the water outflow temperature of the water exiting through the water out nozzle, adjusts the calorific value of the second heater 114 according to the determined water outflow temperature, So that it is allowed to go out to the outflow temperature.

In this state, the controller 122 determines whether an outgoing stop command is generated (S228).

Here, the outgoing stop command may be generated when the user operates a function key for instructing the outgoing / cancellation of certain function keys provided in the key signal input unit 108. The outflow stop command may be automatically generated when a preset time elapses after the water is discharged through the outflow nozzle. In addition, the outgoing stop command may be generated in various ways other than the above-described method.

The control unit 122 returns to step S224 to determine the water outflow temperature of the water to be taken out and adjusts the heating amount of the second heater 114 according to the determined outflow water temperature Repeat the adjustment operation.

Then, the control unit 122 determines whether or not an outgoing stop command is generated (S228). When the outgoing stop command is generated, the controller 122 stops the water outgoing operation (S230) and terminates the water outgoing operation.

The control unit 122 controls the first heater driving unit 112 so as not to supply the heating power to the first heater 110 as well as the second heater driving unit 116 Does not supply the heat generating power to the first heater 114. In addition, the controller 122 controls the inlet solenoid valve 102 to prevent water from being received from the outside, and also controls the outflow valve 120 to prevent water from flowing out through the outflow nozzle.

In the present invention, the controller 122 closes the water inlet valve 102 to continuously open the water outlet valve 120 while preventing water from being received from the outside, The water outlet valve 120 is controlled to be closed when the predetermined time elapses, so that water can be prevented from remaining in the bidet.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, All or some of the embodiments may be selectively combined.
