Description

The structure supply hot water of a refrigerator

The present invention is a combined structure of the cold and hot water device of the refrigerator, and more specifically, to enable the use of cold water and hot water together on the outside of the refrigerator door.

In general, the refrigerator is used for long-term storage and cooling of food and the like at low temperature, and most of the current ones are stored in the refrigerator in a water bottle when storing water, and the refrigerator door is opened and ingested as needed. There is a tank for storing water inside the refrigerator, and after the water is put in, it can be consumed from the outside by using a cup or the like on the valve at the door of the refrigerator.

By the way, when the refrigerator does not have an external valve, the refrigerator frequently opens the refrigerator door during replenishment and intake, and the external valve has no refrigerant to replenish the outside when ingested, but when the user replenishes water, the door is opened manually. It must be replenished, there is a problem that can only store cold water in the refrigerator to buy a water purifier that can be used separately in the cold and hot water.

An object of the present invention is to be able to come out together with cold water and hot water from the outside of the refrigerator door, and do not need to purchase a water purifier separately, eliminating the inconvenience of having to replenish water one by one, combined with a convenient structure of the cold and hot water device of the refrigerator It is to provide.

The present invention is provided with a cold water valve and a hot water valve on the outside of the refrigerator door, the outside of the refrigerator has a hose to connect the water from the bottled water or water purifier, the cold water tank for temporarily storing the water to be used as cold water in the interior And, the door is provided with a combination of cold and hot water device of the refrigerator, characterized in that there is a heater to supply hot water.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows a perspective view of the present invention, there are two valves (16, 18) for supplying cold and hot water to the lower door of the refrigerator, the operation panel 14 for setting the hot water temperature above the The right side of the refrigerator is provided with a wiring 26 and a pump 30 or a solenoid valve 34 serving as a water supply device, as indicated by a dotted line.

Figure 2 shows a cross-sectional view of the lower door, the left side is located in the cold water reservoir 28 that can store cold water, the heater 22 and the cold and hot water valves (16, 18) are located on the right.

3 is an enlarged view of the valve and the heater part, and both sides have a vent 20 to allow air to enter therein, and as shown in FIG. The heat generated in 22) was blocked to prevent heat from being transferred directly to the refrigerator, and between the heaters 22, a heat-insulating material 56 resistant to heat was allowed to keep warm.

5 shows an enlarged view of the valve, wherein the hot water valve 18 and the cold water valve 16 are as shown in the drawing, and the switches 42 and 44 attached to the upper side of the valve when pushed in the direction of the arrow are operated. It was made.

FIG. 6 is a front view of the heater, in which the heater 22 increases the thermal efficiency by allowing water to flow in and discharge upward, and installs a small number of pipes to disperse water and rapidly heats the coil 24. The heater 22 was able to control the electricity supplied to the coil 24 of the heater 22 by using the relay 54 because a large amount of electricity is consumed.

7 shows the installation structure of the pump, the pump 30 when the bottled water bottle 32 is used when the bottled water bottle 32 is low, such as the bottom of the natural supply of water because the pump 30 using When the tap water is used as shown in FIG. 8 without using the bottled water bottle 32, water can be supplied using tap water as a solenoid valve 34, and the water purifier 36 directly intakes tap water. It could not be filtered and then fed. As such, if the user selects the desired water or the tap water, the pump 30 or the solenoid valve 34, which is a water supply device, may be easily replaced.

FIG. 9 is a front view of the operation panel, and includes a set temperature rise 50 and a down switch 52 that must be externally operable, and a seven segment that can display a numerical value pressed by the temperature rise and fall switches. There is a 40, there is a continuous and power saving switch 48 to control the electricity supplied to the heater 22, and the light emitting diode 46 to inform the user that the heater operates continuously when the switch is pressed continuously There is). Such a switch and seven segments are connected to the microcomputer as shown in FIG. 10, and the microcomputer controls the heater relay 54, and the switches 42 and 44 installed in the cold / hot water valves 16 and 18 of FIG. It is also connected to the temperature sensor 38 installed above the heater (22). Then, a pump 30 or a solenoid valve 34 for supplying water is connected. As described above, the devices installed in the respective parts are operated by the microcomputer, and described in the flowcharts shown in FIGS. 11 and 12 as follows.

When the set temperature drop switch 52 is pressed on the operation panel 14, the numerical value is lowered to the seven segments 40 and the numerical value is input from the microcomputer. When the set temperature increase switch 50 is pressed, the numerical value is lowered to the seven segments 40 and the numerical value input to the microcomputer is newly set. When the continuous and power saving switch 48 is pressed once, the heater 22 operates, and the light emitting diode 46 indicating that the heater 22 is continuous is turned on. And, while the heater 22 continues to operate, the temperature detected by the temperature sensor 38 is compared with the set temperature, and when the temperature is equal to or greater than the set temperature, the heating is temporarily stopped for electric saving, and when the temperature is lower than the set temperature, the operation is started again. When the user operates the hot water valve 18 at any time, hot water is supplied immediately, and when the switch 48 is pressed again, the heating is stopped and the light emitting diode 46 is turned off. If the switch 44 installed in the valve is detected and the continuous and power saving switch 48 is continuously maintained, the pump 30 or solenoid valve 34 is operated immediately to supply hot water. 18) the hot water is not supplied immediately, and when the heater 22 is heated above the temperature set by the user, the pump 30 or the solenoid valve 34, which is a water supply device, When the cold water valve 16 is operated, the switch 42 installed in the valve is sensed and the pump 30 or the pump 30 is irrespective of the temperature. Operate solenoid valve 34 to supply water directly.

As described above, according to the present invention, by using the cold water and hot water together from the outside of the refrigerator to eliminate the cost of purchasing the water purifier separately in the home, the user can easily install the desired water or tap water bottled water bottle Or it can be easily connected to the hose regardless of the location of the water, it can provide a convenient structure of the cold and hot water device of the refrigerator.
