It relates to a cold and hot water heater configured to.

In general, cold and hot water refers to a device for supplying cold water and hot water. Recently, as pollution of a water supply source is increased due to factory waste water, more and more places use commercially available bottled water instead of tap water. Offices and homes are also drinking water by installing cold and hot water machines that rapidly cool or heat bottled water.

1 is a cross-sectional view of a general cold and hot water heater showing the flow of bottled water. As shown in the drawing, the cold / hot water machine is composed of a body 10 having a substantially rectangular pillar shape and a bottled water bottle 20 for supplying bottled water, and the take-out cock for intermittently discharging the water of the cold / hot water machine above the front part of the body 10. Although not shown (12), there is formed a discharge portion provided with a drip tray and a drip tray cover.

An intake pipe 15 through which the water is sucked from the bottled water bottle 20 is formed in the main body 10 in which the outlet portion is formed, and the bottled water of the bottled water bottle 20 is formed at one side of the intake pipe 15. The pump 18, which operates to be sucked into the inside, is provided and connected.

FIG. 7 is a flowchart illustrating an operation state of the waterlessness detection system in a cold / hot water heater according to the present invention, and FIG. A schematic diagram showing another embodiment of a waterlessness detection system in a cold / hot water heater according to the present invention is shown.

As shown in these figures, the control device 300 is composed of a control unit 310 for controlling the overall automatic system driving of the cold and hot water machine, and a plurality of unit control unit for individually controlling the driving of each part.

That is, the control device 300 has a water level detecting unit 360 for controlling the water level sensor 114 to detect the water level of the cold water tank 110, the pump according to the water level of the cold water tank (110) Pump driving unit 350 for controlling the operation of the P, the sensor detection unit for controlling the waterless sensor 180 to detect the absence of water in the suction pipe 168 according to the operation of the pump (P). 340, a unit control unit such as a storage unit 320 for storing and storing the water-free detection time of the suction pipe 168 is formed.

The door switch 144 buzzer 372 for ringing the door detector 330 and the buzzer 372 as the door switch 144 is turned on / off. ) Is also connected to the control unit 310.

On the other hand, look at the action of the waterlessness detection system in the cold and hot water heater for the present invention having the configuration as described above are as follows.

When the level of the cold water tank 110 is checked by the water level sensor 114 provided in the cold water tank 110, it is applied to the controller 310 through the water level detector 360, and the controller ( In step 310, the cold water tank 100 checks whether the water level is low (step S11). If the water level of the cold water tank 110 is not low, that is, the high water level, the operation of the pump P is stopped (step S12). Although the waterlessness detection system is completed, when the water level of the cold water tank 110 is a low water level, the pump P is operated through the pump driving unit 350 (step S13).

As the pump P operates, the waterless sensor 180 is turned on (step S14) to detect whether water is sucked into the suction pipe 168. That is, a water detection time and water detection time delay value stored in the storage unit 320 (for example, a value that delays the detection time at intervals of about 5 to 10 seconds to prevent malfunction due to noise). When comparing the suction pipe 168 is determined that there is no water (step S16, step S17) to stop the operation of the pump (P) and make a buzzer sound (step S18).

At this time, if the waterless sensor 180 is not turned on (ON), the water back detection time of the storage unit 320 is cleared and the flow returns to step S11 to detect the water level of the cold water tank 110 again.

Then, when the buzzer sounds in step S18, the user opens and checks the door 140. When it is detected that the door 140 is opened (step S19), the buzzer stops and sets a flag to input that the door 140 is opened once, and the operation of the pump P is performed. Also stop (step S20).

Then, when the door 140 is closed (step S21), a flag for inputting that the door 140 is opened and closed is set (step S22), and resetting the flag setting (step S23). The water level sensor 114 of the cold water tank 110 returns to step S11 to sense the water level, and repeats the above steps (steps S11 to S23).

As described above, the micro switch 184 of the waterless sensor 180 may give an OFF signal to the controller 310 through the sensor detector 340, as shown in FIG. 8. Likewise, it is also possible to provide the waterlessness detection switch S ₁ and the water level detection switch S ₂ at the same time to directly cut off the power of the pump P.

That is, the waterless detection switch (S ₁ ) and the water level detection switch (S ₂ ) is connected in series with each other when any one of the signal is blocked it is possible to configure the pump (P) does not operate.

In addition, the pump P may also be configured not to be automatic as well as electronically.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention may be made by those skilled in the art within the above technical scope.

 In the cold and hot water according to the present invention as described in detail above, a waterless sensor is installed between the pump and the suction pipe is configured to control the operation of the pump by detecting the absence of water in the suction pipe.

Therefore, despite the lack of bottled water in the box-type bottled water, the pump is continuously operated, and the effect of preventing the pump from being damaged due to overload is expected.

In addition, it is expected to have the effect of satisfying the user's product utilization by replacing the bottled water bottle so that the user can easily grasp and move the bottled water bottle which is difficult to move easily due to its large capacity and large weight. do.

In addition, the box-type bottled water container provided in the cold and hot water can be easily and easily removed, replaced and recombined to save the user's time required to replace the box-type water bottle and improve the convenience of use.
