Description

The present disclosure relates to water supply technology for a water server that supplies at least hot water and cold water.

Water servers that provide hot or cold water heat raw water to generate hot water, and cool the raw water to generate cold water. Normally, to obtain hot water from tap water, it is necessary to boil the water, remove residual chlorine and other substances, and then cool it to about 50 to 60 degrees Celsius. It is said that if pure water, natural water, or mineral water is used as raw water, hot water similar to plain water can be obtained without having to boil it like tap water. Therefore, according to the water server using such raw water, hot water can be obtained from the raw water.

Conventionally, regarding beverage supply, a non-contact temperature sensor is provided to measure the temperature of the cup, and if the measured temperature is above a set temperature, a hot beverage is supplied by pressing the beverage selection button, and if it is below the set temperature, the beverage selection button is pressed. It is known to provide a cold beverage by pressing the button (for example, Patent Document 1).

Regarding quality control of liquids, it is also possible to include a temperature sensor that continuously detects the temperature of a drinking container in a non-contact manner, and a temperature determination unit that is electrically connected to the temperature sensor to warm the container at drinking temperature. known (for example, Patent Document 2).

The lock release button 41 is a switch for releasing the locked state of the hot water button 38 and the cold water button 40. During locking, the display section 43 emits light to display that locking is in progress.

<Procedure for water supply and temperature display>
FIG. 3 shows an example of a processing procedure for water supply, temperature detection, and temperature display. This processing procedure is an example of a program of the present disclosure.

When power is supplied to the water server 2, initial settings are executed. If the raw water container 4 is installed, the raw water Wo is supplied to the hot water tank 8 and the cold water tank 10 via the valve mechanism 24, and the hot water tank 8 and the cold water tank 10 are maintained in a full state under normal conditions.

During operation, the control unit 22 monitors the operation of the hot water button 38 and the cold water button 40 (S101, S201). If the hot water button 38 is ON (YES in S101), the hot water solenoid valve 30 is controlled to be open (S102), and the supply of hot water HW is started to enter the water supply state (S103). At this time, the hot water HW is guided from the hot water pipe 26 to the hot water supply port 34 and is supplied to the container 6.

During water supply, the control unit 22 monitors whether the hot water button 38 has transitioned from ON to OFF (S104), and if the hot water button 38 is in the ON state (NO in S104), the hot water solenoid valve 30 is maintained in the open state. Therefore, the hot water HW supply state continues (S103).

If the hot water button 38 is OFF (YES in S104), the hot water solenoid valve 30 is controlled to be closed (S105), water supply is canceled (S106), and the supply of hot water HW is stopped.

Further, when the cold water button 40 is turned on (YES in S201), the cold water electromagnetic valve 32 is controlled to be open (S202), so that the supply of cold water CW is started and the water supply state is established (S203). At this time, the cold water CW is guided from the cold water pipe 28 to the cold water supply port 36 and is supplied to the container 6.

During water supply, the control unit 22 monitors whether the cold water button 40 has transitioned from ON to OFF (S204), and if the cold water button 40 is in the ON state (NO in S204), the cold water solenoid valve 32 is maintained in the open state. Therefore, the cold water CW supply state continues (S203).

If the cold water button 40 is OFF (YES in S204), the cold water solenoid valve 32 is controlled to be closed (S205), water supply is canceled (S206), and the supply of cold water CW is stopped.

In these water supply controls, when the hot water solenoid valve 30 or the cold water solenoid valve 32 shifts to the open state, the temperature detection mode of the water W in the container 6 is entered (S301). The temperature sensor 18 detects the temperature of the water W in the container 6 in a non-contact manner (S302). Temperature detection information from the temperature sensor 18 is taken into the control unit 22, and the temperature of the water W is calculated. The temperature detected by the temperature sensor 18 is displayed on the temperature display section 42 (S303).

In this temperature detection mode, the control unit 22 determines whether to cancel the temperature detection mode (S304). If the temperature detection mode is not canceled (NO in S304), the temperature display is continued (S303), and if the temperature detection mode is canceled (YES in S304), the temperature display is canceled (S305).

In this way, after water is supplied to the container 6 or after water is supplied, the temperature of the water W can be known from the temperature display on the temperature display section 42, and if this temperature is lower than the desired temperature, the hot water button 38 is operated and the temperature of the water W is If this temperature is higher than the desired temperature, the cold water button 40 is operated to add cold water CW to the container 6, and the temperature of the water W can be adjusted to the desired temperature.

It is displayed (S713).

<Water supply at set temperature Tt>
With respect to the volume M of the container 6 (for example, 200 cc), the amount of water supplied to the container 6 Mt is set to Mt<M.

When the set temperature Tt is selected, the duty Dh (seconds) of the hot water solenoid valve 30 and the duty Dc (seconds) of the cold water solenoid valve 32 are determined in order to realize the water supply amount Mt of the set temperature Tt to the container 6. .

When the hot water button 38 is pressed, the hot water solenoid valve 30 becomes open, and this open state is maintained for a duty Dh (seconds). This supply of hot water HW is performed at a duty Dh (seconds) regardless of the pressing time of the hot water button 38.

Note that in the sixth embodiment, the temperature table 108 (B in FIG. 13) is used to obtain the duty ratio of opening and closing of the hot water solenoid valve 30 and the cold water solenoid valve 32, but the present disclosure uses this temperature table 108 (B in FIG. 13). The use of table 108 is not limited. Instead of this temperature table 108, the control unit 22 calculates and controls the duty ratio of the hot water solenoid valve 30 and the cold water solenoid valve 32 by inputting temperature information representing the set temperature and the current temperature of the hot water HW and cold water CW. It may also have a function. Regarding the calculation of this duty ratio, the duty ratio may be calculated using a function (formula) using the set temperature and current temperature of the water W.

The hot water button 38 and the cold water button 40 are examples of operating means for instructing the start of temperature detection and temperature display in synchronization with the start of hot water HW or cold water CW supply.

The temperature display section 42 displays the detected temperature of the water W using an LCD (Liquid Crystal Display) or a plurality of LED (Light Emitting Diode) displays. This temperature display may be either a numerical display representing the temperature or an indicator serving as a guide for the temperature range.

Regarding the temperature correction processing 134, the present disclosure is not limited to processing by arithmetic processing by the control unit 22, but correction processing is performed on the output signal of the non-contact temperature detection element 120 using an electric circuit (not shown) outside the control unit 22. After the detection information is applied, the detection information may be taken into the control unit 22.
