Temperature control method of cold and hot water purifier

The present invention is a method for controlling the temperature of the cold water and / or hot water of the cold and hot water purifier to supply cold water and hot water at the same time, more specifically, the temperature of the cold water and hot water, which was fixed at a single value in the prior art appropriately according to the season It relates to a temperature control method of a cold and hot water purifier that can be set.

Since drinking water is not directly consumed due to pollution, most households receive drinking water using water purifiers. These water purifiers have the advantage that the main component of the contamination is removed because the foreign substances contained in the drinking water using various filter means can be safely drinking. The water purifier as described above can be divided into ones having a simple function from a variety of functions, one of which is a cold and hot water purifier that can supply cold water and hot water at the same time.

The cold and hot water purifier divides the purified water supplied through the filter means into two tanks, that is, the cold water tank and the hot water tank, and then cools and supplies the purified water stored in the cold water tank using a cooler, and uses the heater to store the purified water. The purified water is heated up and supplied.

However, in the conventional cold and hot water purifier, referring to FIG. 2, since the temperature of the cold water and the hot water temperature (for example, the cold water temperature of 3 ° C. and the hot water temperature of 85 ° C.) are determined in advance in the design stage, the user may change the temperature. There was uncomfortable. This is because it is impossible to use the boiled water at a higher temperature than that set in the case of using the hot water for coffee, and there is an inconvenience of having to reheat the hot water. In addition, because the cold and hot water temperature is always fixed, there is a problem in that energy is wasted because it can not be adjusted according to the season, such as summer or winter.

Hereinafter, the temperature control method of the cold / hot water purifier of the present invention will be described in detail with reference to the accompanying drawings.

The temperature control method of the cold / hot water purifier of the present invention not only provides convenience in use by resetting the temperature of cold water and hot water, which could not be changed by the user to a desired degree, but also cold water and hot water according to the change of the season. It is a temperature control method of cold / hot water purifier that can save energy by resetting temperature.

The method of the present invention can be carried out in a conventional circuit diagram as shown in FIG. 1 and the following steps: cold water and / or hot water temperature input from the operation / display section when the water purifier is operated and a temperature reset input by the user is detected. Storing the; Resetting the cold water and / or hot water temperature to the standard set temperature if the temperature reset input is not detected; Measuring cold water and / or hot water temperature using a cold water sensor and a hot water sensor; Driving the heater and / or the cooler if the measured cold water and / or hot water temperature does not satisfy the set temperature value; And measuring cold water and hot water temperatures in a state where the heater and / or the cooler is driven, and stopping driving of the heater and / or the cooler when the set temperature is satisfied.

First, an operation state of each component of the circuit diagram of FIG. 1 will be briefly described.

The microcomputer 2 has a built-in program for controlling the entire stroke, and the raw water valve 4 is for supplying tap water for the water purification operation in the filter means (not shown). In addition, the circulation pump 6 serves to be filtered by the filter means by forcibly moving the tap water. The singular switch 8 is used to stop the operation of the water purifier by detecting it when it becomes the singular and transmitting it to the microcomputer 2. The sterilization lamp 10 is for killing bacteria contained in the filtered purified water. In addition, the water level sensor 12 detects the water level of the purified water tank, that is, the cold water tank and the hot water tank, and delivers it to the microcomputer 2, and the microcomputer 2 detects the water level signal and the water level drops below the prescribed water level. The raw water valve 4 and the circulation pump 6 are operated to perform the water purification operation. Cold water sensor 14 is a temperature sensor for measuring the temperature of cold water, hot water sensor 16 is a temperature sensor for measuring the temperature of hot water. In addition, 18 is an operation / display unit for inputting a command by a user and displaying the state of the current water purifier. The heater 20 is installed inside the hot water tank to raise the temperature of the purified water, and the cooler 22 is used to cool the purified water.

In the method of the present invention, when the water purifier is operated, the present cold / hot water temperature display state is first displayed on the operation / display unit 18. In this state in which the temperature is displayed, the microcomputer 2 waits for a command input by the user. The user inputs a control signal to the microcomputer 2 using a command input device such as a switch provided in the operation / display section 18.

If the command by the user is a temperature reset input, the microcomputer 2 outputs a menu for temperature reset via the operation / display unit 18. The user can view the output set status and enter a command for setting the standard temperature or reset the cold and / or hot water temperature. The setting signal pressed by the user is input to the microcomputer 2 and stored in the internal memory or the like.

In the microcomputer 2, after the setting input of the temperature is completed, the temperature is measured using the cold water sensor 14 and the hot water sensor 16, respectively. The cold and hot water sensors 14 and 16 can be constructed using essentially the same sensors. The microcomputer 2 measuring the temperature of cold water and hot water compares the temperature reset by the user with the measured temperature.

As a result of this comparison, when the temperature of the cold water and / or the hot water is out of the set temperature, the microcomputer 2 performs a necessary operation for adjusting the temperature to the set temperature. That is, if the cold water temperature is higher than the set temperature, the microcomputer 2 drives the cooler 22 to lower the cold water temperature. In addition, when the temperature of the hot water is lower than the set temperature to drive the heater 20 to increase the temperature of the hot water. The heater 20 or the cooler 22 may be operated individually or simultaneously depending on the respective temperature conditions.

As described above, the microcomputer 2 drives the heater 20 and / or the cooler 22 to detect the temperature change while continuously measuring the temperature using the cold water sensor 14 and the hot water sensor 16. Hot and cold water temperature changes occur according to the operation of the heater and the cooler, and when the set temperature is reached, the microcomputer 2 selectively stops the corresponding device (heater or cooler) to maintain the temperature.

Temperature setting in the present invention can be carried out as follows. For example, the cold water temperature may be set to 1 ° C. or 5 ° C. based on 3 ° C., which is a standard temperature, to set the cold water temperature to 1 ° C. in summer, and to 5 ° C. in winter. In addition, by setting the hot water temperature, such as 81 ℃, 83 ℃, or 87 ℃ based on the standard temperature 85 ℃ for the winter season can be set to 87 ℃ in the winter season and 81 ℃ in the summer season.

As another temperature setting example, it is possible to configure the cold water and hot water temperatures in pairs to designate them collectively. That is, in summer, the cold water temperature may be set at 1 ° C. and the hot water temperature may be adjusted at 81 ° C. at the same time. In winter, the cold water temperature may be set at 5 ° C. and the hot water temperature at 87 ° C. at the same time. Such a temperature setting mode can be set programmatically in the microcomputer 2. The above temperature setting examples are for explaining the present invention, and it is obvious to those skilled in the art that the present invention does not limit the scope of the present invention.

When the temperature of the hot water and / or cold water reaches the set temperature in the state where the heater 20 and the cooler 22 are driven as described above, the microcomputer 2 stops the operation of the device and the next command is input from the user. Another sensing device, for example, waits for the input of a signal for water replenishment from the water level sensor 12. At this time, the reset temperature data is stored in the microcomputer 2, and when the temperature reset input is detected, it is displayed as a conventional set temperature.

As described above, according to the present invention, there is an advantage that the user can appropriately set the temperature of the cold water and the hot water, which are fixed at a single value according to the season.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
