In addition, since a separate control configuration is not required by manually opening and closing the cooling water valve 20 , manufacturing cost can be reduced.

The configuration of the cooling water valve 20 will be described with reference to FIG. 2 .

The cooling water valve 20 includes a first connector 21 and a second connector 22 respectively connected to the cooling water line L6, and a constant between the first connector 21 and the second connector 22. A valve housing 23 having a valve member (not shown) therein in order to flow or block the flow, a handle 24 connected to the valve member to be integrally rotatable and having a straight shape in a plan view ), is formed integrally with the handle 24 and provided on the upper portion of the valve housing 23 to rotate with the handle 24 when the handle 24 is rotated.

When the handle 24 is positioned in a direction perpendicular to the line connecting the first connector 21 and the second connector 22 as shown in Fig. 2(a), the cooling water valve 20 is in a closed state, and As shown in 2(b), when the handle 24 is positioned in a direction parallel to the line connecting the first connector 21 and the second connector 22, the coolant water valve 20 is in an open state, and the handle ( 24) by holding and rotating the cooling water valve 20 is closed or opened.

The configuration of the cooling tank 30 will be described with reference to FIG. 3 .

The cooling tank 30 includes a tank body 31 for accommodating cooling water in the inner space S, and a cold water pipe 32 in which purified water supplied through the third purified water line L4 flows through the inside, and cold water is generated. ), a refrigerant pipe 33 for cooling the coolant, a water level sensor 34 for detecting the level of the coolant, a coolant temperature sensor 35 for detecting the temperature of the coolant, and agitating the coolant A stirrer 36 for equalizing the temperature, an inlet and outlet 37 for introducing purified water for generating cooling water into the inner space S or draining the cooling water from the inner space S, the tank body 31 It is made of an insulating material 38 surrounding the outside.

The tank body 31 is made of a synthetic resin material, and has a substantially rectangular cylindrical shape so that cooling water is accommodated in its inner space (S).

In the cold water pipe 32, the purified water at room temperature that has passed through the filter 10 is introduced through one end 32a to heat exchange with the cooling water to generate cold water having a lowered temperature, and the generated cold water is supplied when the user requests water to be discharged. The cold water is discharged through the water outlet 9 through the other end 32b of the cold water pipe 32, the cold water outlet line L5, and the cold water outlet valve 7 in sequence.

The refrigerant pipe 33 is composed of an evaporator of the refrigerating cycle, and the refrigerant evaporates therein and absorbs heat around the refrigerant pipe 33 to cool the cooling water.

The water level sensor 34 includes a full water level detecting unit 34a for detecting a full water level, and an overflow detecting unit 34b for detecting an overflow water level to prevent the coolant from overflowing as a water level higher than the full water level.

A control method of the water treatment apparatus 1 of the present invention will be described with reference to FIGS. 4 and 5 .

Since the cooling water is formed by cooling the purified water flowing into the cooling tank 30 , hereinafter referred to as purified water until it flows into the cooling tank 30 , and purified water after flowing into the cooling tank 30 is referred to as cooling water. do.

In step S101, power is applied to the water treatment device 1 . When power is applied, the water level sensor 34 detects the coolant level in the cooling tank 30 . In this case, the raw water valve 13 is in a closed state.

As a result of detecting the coolant level in step S102, the controller (not shown) determines whether the coolant level is an overflow level. If it is determined that the overflow level is the overflow level, the process proceeds to step S109; otherwise, the process proceeds to step S103.

In step S103, the control unit determines whether the coolant level is the full water level. If it is determined that the water level is full, it is determined that the user is in a state in which cold water can be normally dispensed, and the standby state is entered.

In step S104, the control unit outputs a cooling water supplement alarm to the user. In this case, the control unit may output an alarm informing that cooling water replenishment is required in the form of a voice or an alarm sound, may be output in the form of a text message through the display, or may be output by blinking or lighting an LED lamp. . By outputting such an alarm, the user can recognize that cooling water replenishment is required.

In step S105, the control unit opens the raw water valve 13. When the raw water valve 13 is opened, the purified water passing through the filter 10 flows to the cooling water supply line L6 through the first purified water line L2. In this case, since the cooling water valve 20 is in a closed state, as shown in FIG.

In step S106, purified water is obtained into the cooling tank 30 by opening the cooling water valve 20. In order to obtain the purified water, the user rotates the handle 24 of the cooling water valve 20 to open the cooling water valve 20 . When the cooling water valve 20 is opened, purified water flows into the cooling tank 30 through the cooling water intake line L6 and the cooling water discharge line L7 as shown in FIG. 5(b). As such, when purified water flows into the cooling tank 30 , the water level sensor 34 detects the level of the cooling water filled in the cooling tank 30 .

In the above description, the cooling water valve 20 is opened in S106 after the raw water valve 13 is opened in step S105. However, when the coolant supplement alarm is output in step S104, the user opens the coolant water valve 20, and the It may be configured such that purified water is obtained in the cooling tank 30 by opening the raw water valve 20 afterward.

In step S107, the control unit determines whether the coolant level is the full water level. If it is determined that the water level is full, it is determined that the cooling water replenishment has been completed, and the flow proceeds to step S108. Otherwise, purified water is continuously introduced.

In step S108 , the control unit outputs an alarm to notify the user that the water level has reached the full water level, and closes the raw water valve 13 so that purified water is no longer introduced into the cooling tank 30 .

Thereafter, the user rotates the handle 24 to close the cooling water valve 20 , thereby ending the cooling water replenishment process and entering a standby state in which cold water can be dispensed.

All alarm output methods described below, including the full water level alarm output method in step S108, may be configured to be output in the same way as the cooling water supplement alarm output method in step S104.

Meanwhile, if it is determined in step S102 that the coolant level corresponds to the overflow level, steps S109 to S113 and S104 to S108 are performed to adjust the coolant level to the full level. In this case, when the overflow water level is sensed while the raw water valve 13 is open, the control unit closes the raw water valve 13 and then the process after step S109 is performed.

In step S109, the control unit outputs a coolant drain alarm to the user. When the coolant drain alarm is output, the user removes the drain stopper blocking the end of the coolant drain line L8.

When the drain plug is removed in step S110, the cooling water in the cooling tank 30 is drained through the cooling water drain line L7 and the cooling water drain line L8 as shown in FIG. 5(c). As the drainage proceeds, the water level detected by the water level sensor 34 decreases.

In steps S111 and S112, the controller determines whether the coolant level corresponds to the overflow water level or the full water level. As a result of the determination, if it is determined that the coolant level is lower than the full water level and does not correspond to both the overflow water level and the full water level, the process proceeds to step S113. Otherwise, the water level is continuously detected.

In step S113, the control unit outputs a full water level release alarm to the user. When the full water level release alarm is output, it means that the coolant level is lower than the full water level. Accordingly, the user closes the end of the cooling water drain line L8 with the drain plug, steps S104 to S108 are performed, the cooling water is filled in the cooling tank 30 to the full level, and the user closes the cooling water valve 20 to It becomes possible to exit.

As such, in steps S109 to S113, if the coolant level is the overflow level, the coolant is drained continuously in step S110 until the water level is lower than the full water level and a full water level release alarm is output. have.

In step S113, a full water level release alarm is output when the coolant level is lower than the full water level, but it may be configured to output an alarm when the full water level is detected by the water level sensor 34. Even if the full water level detection alarm is output as described above, the cooling water continues to drain until the user closes the end of the cooling water drain line L8 with the drain plug, so that the cooling water level is lower than the full water level. After that, the user closes the end of the cooling water drain line L8 with a drain plug, and steps S104 to S108 are performed.

In addition, in the above configuration, after outputting the full water level release alarm in step S113 and then outputting the coolant replenishment alarm in step S104, the coolant replenishment alarm step in step S104 is not performed, and it may be configured to proceed from step S113 to S105 have.

After that, when the user requests the cold water to be discharged, the raw water valve 13 and the cold water outlet valve 7 are opened by the control unit as shown in FIG. Water is discharged through the water outlet 9 through the (L5).

If the cold water is discharged in a state where the user does not close the cooling water valve 20 after the source water valve 13 is closed in step S108, the purified water passing through the source water valve 13 is transferred to the cooling water line L6. , flows into the cooling tank 30 through the cooling water drain line L7 and is filled with cooling water up to the overflow level.

In this case, when the control unit closes the raw water valve 13 by detecting the overflow water level in the overflow detection unit 34b of the water level sensor 34, the cooling tank 30 blocks the additional inflow of purified water to cool It is possible to prevent the coolant inside the tank 30 from overflowing.

However, in this case, since the overflow detection unit 34b detects the overflow level, the processes of steps S109 to S113 and S104 to S108 proceed. There is a problem in that the cold water is not discharged until the valve 20 is closed, and the above process is repeated.

In order to solve this problem, it is necessary to allow the user to easily recognize the open/closed state of the cooling water valve 20 . Hereinafter, a structure for allowing the user to recognize the open/closed state of the cooling water valve 20 will be described.

The arc inner surface 55-2d of the second rib body part 55-2a is provided to face the first interfering rib 55-1, so that the cooling water valve 20 is closed. The handle 24 can be positioned without interference in a space spaced apart in the front-rear direction between the first interfering rib 55-1 and the second interfering rib 55-2.

The lower ends of the first interfering rib 55-1 and the second interfering rib 55-2 protrude further downward than the lower ends of the cover flange 52 and the hook 53, so that the main body cover 50 is attached to the main body. When the first interfering rib 55-1 and the second interfering rib 55-2 are opened before the hook 53 is inserted into the cutout 42 when coupled to the housing 40, the cooling water valve ( 20), the coupling of the body cover 50 and the body housing 40 is not made.

Since it does not matter if it is formed at any position, it may be configured to protrude downward from the cover body 51 .

A process of coupling the body cover 50 to the body housing 40 will be described with reference to FIGS. 7 and 8 .

First, a process of coupling the body cover 50 to the body housing 40 in a state in which the cooling water valve 20 is closed will be described.

As shown in FIG. 7( a ), the main body cover 50 is lowered to the open upper part of the main body housing 40 in the state in which the cooling water valve 20 is closed. In this case, the hook 53 of the body cover 50 is inserted into the rear cutout 42b of the body housing 40 . In this case, as shown in Fig. 8(a), the handle 24 of the cooling water valve 20 is formed between the first interfering rib 55-1 and the second interfering rib 55-2 when the cooling water valve 20 is closed. The first interfering rib 55-1 and the second interfering rib 55-2 are positioned parallel to each other in the spaced apart space, and the handle 24 is the first interfering rib 55-1 and the second interfering rib 55-1. It is in a state of being spaced apart without interference from the ribs 55-2.

Then, as shown in FIG. 7(b), when the main body cover 50 is pushed forward and the hook engaging part 53b of the hook 53 is moved to the position of the front incision part 42a, the hook engaging part 53b is moved to the front The cutout portion 42a is caught by the housing flange 41 formed therein, and separation of the main body cover 50 is prevented. In this case, as shown in Fig. 8 (b), the second interfering rib 55-2 moves forward, and on both ends of the arc inner surface 55-2d of the second interfering rib 55-2, both sides of the handle 24 ends are in contact.

The body cover 50 is coupled to the body housing 40 by the above process.

As shown in FIG. 7( c ), the main body cover 50 is lowered to the open upper part of the main body housing 40 in the state in which the cooling water valve 20 is opened. In this case, the length of the handle 24 is formed longer than the spaced distance between the first interfering rib 55-1 and the second interfering rib 55-2, as shown in FIGS. 7(d) and 8(c). As shown, since the front and rear ends in the longitudinal direction of the handle 24 come into contact with the lower ends of the first and second interfering ribs 55-1 and 55-2, the main body cover 50 cannot descend any more. The hook 53 is not inserted into the rear incision 42b. Therefore, the user can recognize that the water cooling water valve 20 is in an open state, rotating the handle 24 to close the cooling water water valve 20 and then coupling the body cover 50 to the body housing 40. can

Next, a case in which the main body cover 50 is coupled to the body housing 40 in a state in which the cooling water valve 20 is located between the closed position and the open position and is partially opened will be described with reference to FIG. 9 .

When the main body cover 50 descends while the cooling water valve 20 is partially opened, the hook 53 is inserted into the rear incision 42b, and the handle 24 is the first interfering rib 55-1. and the second interfering rib 55-2 may be positioned without interference.

When the main body cover 50 is pushed forward in this state, one end of the handle 24 comes into contact with the arc inner surface 55-2d of the second interfering rib 55-2 as shown in FIG. will do

Then, when the main body cover 50 is continuously pushed forward, as shown in FIGS. 9(b) to 9(e), one end of the handle 24 is in contact with the arc inner surface 55-2d. In the handle 24 is rotated clockwise.

Continue to push the main body cover 50 forward so that the main body cover 50 completely covers the open upper part of the main body housing 40 so that the hook engaging part 53b of the hook 53 closes the front incision part 42a. When the position is reached, as shown in FIG. 9(f), the cooling water valve 20 is in a closed state.

According to this configuration, even when the main body cover 50 is coupled to the main body housing 40 in a state in which the cooling water valve 20 is partially opened, the handle 24 of the cooling water water valve 20 is connected to the second interfering rib 55 -2) automatically rotates the cooling water valve 20 into a closed state.

Therefore, when the cooling water valve 20 is open, the body cover 50 is not coupled to the body housing 40 due to the interference between the interference ribs 55-1 and 55-2 and the cooling water valve 20. Due to this, the user can recognize the open state of the cooling water valve 20, and when the cooling water valve 20 is partially open, the cooling water valve 20 is closed by the second interfering rib 55-2. Since it automatically closes, the main body cover 50 is coupled to the main body housing 40 while the cooling water valve 20 is at least partially opened to prevent the water treatment device 1 from operating.

As described above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims, the detailed description of the invention, and the accompanying drawings. It is possible to carry out and this also belongs to the present invention.
