Description

Description: TECHNICAL FIELD The present invention relates to a controller for a clothes dryer capable of storing dehumidified water.

2. Description of the Related Art A conventional clothes dryer is installed and used in a specific place together with a washing machine, and a dehumidification type in which dehumidification water is drained through a hose becomes mainstream. Things that can be easily changed in places have been desired.

However, simply draining through a hose is inconvenient.

Therefore, a mechanism has been considered in which the dehumidifying water can be temporarily stored, removed and discarded as needed, and a function can be used to drain the water using a hose in a specific place as in the past. It is necessary to determine not only the amount of water and the presence or absence of a water storage case, but also whether it is a water storage type or a drainage hose type, and it is necessary to determine the state by using multiple input terminals or a matrix by combining multiple output terminals and input terminals The way has been taken.

 An example is shown in FIG.

In FIG. 4, reference numeral 40 denotes a digital input unit, which is provided with three input terminals, to which are respectively connected a dehumidified water storage means presence / absence detecting means 41, a dehumidified water amount detecting means 42, and a dehumidified water draining method selecting means 43. I was Each of the detection means 41 to 43 outputs a detection state signal, and the digital input section 40 converts the signal into a digital signal, and the comparison operation processing section 45 determines the state.

Problems to be Solved by the Invention However, occupying three input terminals in a control device using a 4-bit microcomputer as described above has a problem that redundancy is large and other functions are restricted. .

In view of the above problems, it is an object of the present invention to make it possible to determine many states with one input terminal and to minimize restrictions on other functions.

Means for Solving the Problems In order to achieve the above object, the technical means of the present invention comprises:
Water storage means for temporarily removing and draining dehumidified water, detecting means for detecting the presence or absence of the water storage means, detecting means for accumulated dehumidified water, and detecting means for selecting a method of draining dehumidified water. A detection unit that outputs the respective detection units as a signal in a state in which the detection units are integrated into one; a storage unit that previously has a combination of the respective detection units as a state determination numerical value group; and an output from each of the detection units. And a comparison operation unit for comparing and discriminating the state discrimination numerical value group of the storage unit, and a control unit for notifying an abnormality or driving each load based on the discrimination result of the comparison operation unit.

According to the above technical means, a detecting means for outputting each detecting means as a signal in a state in which the detecting means are integrated into one, a storage unit having a combination of the respective detecting means in advance as a state discriminating numerical value group, Since there is provided a comparison operation unit for comparing and judging the output from the detection means and the state judgment numerical value group of the storage unit, it is possible to judge the amount of dehumidified water and the presence / absence of a water storage case with one input terminal. It is possible to determine and control whether it is a water storage type or a drainage hose type, and it is possible to judge abnormalities in the detection means and circuits, and it is possible to temporarily stop operation, report abnormalities, restart, etc. without waste .

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing an apparatus for determining the state of dehumidified water in an embodiment of the present invention. In the figure, reference numeral 1 denotes an analog value generating means in the state of dehumidified water, detecting means 2 for detecting the presence or absence of a water storage means for temporarily storing dehumidified water, detecting means 3 for detecting the amount of accumulated dehumidified water, and drainage of dehumidified water. A detection means for outputting a signal in a state where the method selection means 4 are gathered together constitutes a detection means. Regarding the configuration of each of the detection means 2 to 4, the second
This will be described later with reference to the drawings. Reference numeral 5 denotes an analog value input unit, 6 denotes an A / D converter for converting an analog value into a digital signal, and 7 denotes a storage unit, which stores various determination results and a progress state. Reference numeral 8 denotes a state discriminating value group in the storage unit. 9 compares the signal from the combination state detecting means with the numerical value group 8 in the storage unit 7,
A comparison operation processing unit that determines a combination state regarding dehumidification water,
Reference numeral 10 denotes a control unit that controls a notification unit 11 that notifies the determination result and various loads 12.

The analog signal by the combination state detecting means is represented by A-
It is converted into a digital signal via a D converter 6, and the numerical value is compared with the numerical value group 8 in the storage unit 7 in the comparison operation unit 9 to determine the combination state. In addition to performing notification of the presence / absence of means, notification of the amount of stored water, and load control, notification of circuit abnormality and load control can be performed as necessary.

FIG. 2 shows an example of the configuration of the analog value generating means in the state of the dehumidifying water. As shown in the drawing, a detecting means 2 for detecting the presence or absence of a water storage means for temporarily storing dehumidified water, a detecting means 3 for detecting the amount of accumulated dehumidified water, and a selecting means 4 for a method of draining dehumidified water are each provided with: Switches S2 to S4 having ON and OFF states corresponding to the states, fixed resistors R2 to R4 connected in series, and a combination of fixed resistors R1 and R5 combined into one,
The power supply voltage V _DD of the microcomputer has a relationship as shown in FIG. 3, and the control center unit 10 controls various loads according to the respective relationships.

Therefore, when a voltage out of the state related to the dehumidification water is input, it is determined that the detection unit or the circuit is abnormal, and the operation can be stopped or the abnormality can be immediately reported.

Effects of the Invention As is clear from the above embodiments, according to the present invention,
In addition to determining a plurality of states for one input terminal, it is possible to realize the determination of an abnormal state at low cost without using a plurality of input terminals.
