Description

[Technical Field]

[0001] The present disclosure relates to a water supply technology for a water server that supplies at least hot water and cold water. [Background technology]

[0002] Water servers that provide hot and cold water heat raw water to produce hot water and cool it to produce cold water. Normally, to obtain hot water from tap water, the tap water must be boiled, residual chlorine and other substances removed, and then cooled to around 50-60°C. It is said that if pure water, natural water, or mineral water is used as the raw water, hot water similar to hot water can be obtained without boiling it like tap water. Therefore, water servers that use such raw water can obtain hot water from the raw water.

[0003] Conventionally, with regard to beverage supply, it is known that a non-contact temperature sensor is provided to measure the temperature of a cup, and if the measured temperature is equal to or higher than a set temperature, a hot beverage is supplied by pressing a beverage selection button, and if the measured temperature is lower than the set temperature, a cold beverage is supplied by pressing a beverage selection button (for example, Patent Document 1).

[0004] Furthermore, with regard to the quality control of liquids, it is known to have a temperature sensor that continuously detects the temperature of a drinking container without contact, and a temperature determination unit that is electrically connected to this temperature sensor and heats the container to drinking temperature (for example, Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-176484 [Patent Document 2] Japanese Patent Application Publication No. 2019-104541 Summary of the Invention [Problem to be solved by the invention]

[0006] In water dispensers, the cold or hot water dispensed is controlled to a predetermined temperature within the dispenser. Some water dispensers have several temperature settings, such as hot water, hot water, cold water, and slightly cold water. Even with these temperature settings, it is not possible to dispense water at a temperature intermediate between the specified hot and cold water temperatures. To obtain this intermediate temperature, the user must fill a container with an appropriate amount of hot water and add cold water to it to fine-tune the temperature. Furthermore, since the water temperature after mixing cannot be accurately determined, temperature adjustment has generally relied on intuition and feeling. Even if it is possible to measure the temperature inside the container, using a thermometer on a daily basis is inconvenient, and there are issues such as the difficulty of adjusting the temperature of foods and beverages that require a specified temperature.

[0007] In view of such problems, the inventors of the present disclosure have come to the realization that the convenience of water servers can be further improved if the temperature of water in a cup dispensed from the water server can be known.

[0008] Therefore, based on the above problems and findings, the object of the present disclosure is to improve the convenience of water servers by enabling the display of the detected temperature or target temperature of water being supplied from the water server to a container or after water has been supplied. [Means for solving the problem]

[0009] In order to achieve the above object, according to one aspect of the water server of the present disclosure, there is provided a water server including a hot water tank for generating and storing hot water, a cold water tank for generating and storing cold water, a temperature setting button for setting an arbitrary target temperature, and a water supply unit that, when supplying the hot water, opens a hot water solenoid valve to supply the hot water to a container, and, when supplying the cold water, opens a cold water solenoid valve to supply the cold water to the container, or supplies a mixture of the hot water and the cold water to the container; a temperature table storing opening and closing times of the hot water solenoid valve and the cold water solenoid valve corresponding to the target temperature; a temperature detection unit that detects the temperature of the water in the container; and a temperature display unit that displays the target temperature or the detected temperature in the container; When the target temperature is set by the temperature setting button, the set target temperature is displayed on the temperature display unit, and the opening and closing times corresponding to the target temperature read from the temperature table are set in the hot water solenoid valve and the cold water solenoid valve, The hot water or cold water supply but start When this is done, one or both of the hot water and the cold water are supplied in accordance with the set opening and closing times of the hot water solenoid valve and the cold water solenoid valve, and a control unit that switches the temperature display of the temperature display unit from the target temperature to the detected temperature.

[0010] In this water server, the control unit may change the valve opening ratio of the hot water solenoid valve and the cold water solenoid valve based on the setting of the target temperature.

[0011] In this water server, the temperature detection unit may include a non-contact temperature sensor that detects at least the surface temperature of the water in the container in a non-contact manner.

[0012] In this water server, the temperature detection unit may detect the temperature of the water entering the container from the water supply unit.

[0013] In this water server, the control unit may cancel the temperature detection and the temperature display after a certain time has elapsed since the hot water solenoid valve and the cold water solenoid valve were closed. [Effects of the Invention]

[0014] According to the present disclosure, any of the following effects can be obtained.

[0015] (1) Since the detected temperature or target temperature of water can be displayed during or after water is dispensed from the water dispenser to the container, it is possible to easily check whether the detected temperature has reached the target temperature.

[0016] (2) The temperature of the water in the container can be detected while or after the water is being supplied from the water server to the container, and the temperature is displayed on the temperature display unit, so that the water temperature in the container can be easily known from the temperature display unit, thereby increasing the convenience of the water server.

[0017] (3) Since the temperature of the water in the container can be known during or after the water dispenser has dispensed water into the container, additional hot or cold water can be dispensed depending on the temperature, making it easy to adjust the water in the container to the target temperature, thereby further increasing the convenience of the water dispenser.

[0019] [First embodiment] The water server 2 according to the first embodiment detects the temperature of the water W in the container 6 during or after water is supplied from the water supply unit 16 to the container 6 such as a cup, and displays this temperature. This temperature display allows the user to know the temperature of the water W in the container 6 during or after water is supplied.

[0020] <Water Server 2> Fig. 1 shows a water server 2 according to a first embodiment. Fig. 1 shows an example of the present disclosure, and the present disclosure is not limited to such a configuration.

[0021] This water server 2 receives raw water Wo from a raw water container 4 such as a gallon bottle, produces at least cold water CW or hot water HW, and can supply the water to a desired container 6 such as a cup by a water supply operation.

[0022] The hot water tank 8 receives raw water Wo from the raw water container 4 through the valve mechanism 24, and heats it in the hot water tank 8 using the heating unit 12 to generate hot water HW. The hot water HW is controlled to a constant high temperature by the control unit 22 and stored in the hot water tank 8.

[0023] Similarly, the cold water tank 10 receives raw water Wo from the raw water container 4 through a valve mechanism 24, and cools it using the cooling unit 14 to produce cold water CW. The cold water CW is controlled to a constant low temperature by the control unit 22 and stored in the cold water tank 10.

[0024] Water supply unit 16 receives a water supply instruction and supplies hot water HW or cold water CW under the control of control unit 22. Hot water pipe 26 is connected to hot water tank 8, and when supplying water, guides hot water HW from hot water tank 8 to hot water supply port 34. In addition, cold water pipe 28 is connected to cold water tank 10, and when supplying water, guides cold water CW from cold water tank 10 to cold water supply port 36.

[0025] A hot water solenoid valve 30 installed in the hot water pipe 26 opens and closes the hot water pipe 26 under the control of the control unit 22. A cold water solenoid valve 32 installed in the cold water pipe 28 opens and closes the cold water pipe 28 under the control of the control unit 22. When supplying hot water HW, the hot water solenoid valve 30 is controlled to an open state, and the hot water HW guided from the hot water tank 8 to the hot water supply port 34 is supplied to the container 6. When supplying cold water CW, the cold water solenoid valve 32 is controlled to an open state, and the cold water CW guided from the cold water tank 10 to the cold water supply port 36 is supplied to the container 6.

[0026] Temperature sensor 18 is an example of a temperature detection unit disclosed herein. This temperature sensor 18 is composed of an infrared temperature sensor that detects at least the surface temperature of the water W in container 6 without contact. This infrared temperature sensor detects infrared rays emitted from the water W in container 6, and this detection information is provided to control unit 22. Control unit 22 receives the detection information from temperature sensor 18, converts it into temperature information, and measures the temperature of the water W in container 6. Therefore, during or after water is being supplied, temperature sensor 18 detects infrared rays, and the temperature of the water W in container 6 can be calculated from this infrared rays. Hereinafter, the temperature detected by temperature sensor 18 will be referred to as the "detected temperature" or the "temperature of water W."

[0027] The operation panel unit 20 includes a hot water button 38, a cold water button 40, a temperature display unit 42, etc. The hot water button 38 is operated (for example, pressed) when supplying hot water HW. The cold water button 40 is operated when supplying cold water CW. The temperature display unit 42 is configured, for example, with a segment display, and displays the detected temperature as the temperature of the water W in the container 6 based on temperature information acquired by the control unit 22 from the temperature sensor 18 during or after water supply. This temperature display unit 42 may include, for example, an indicator lamp that displays different temperatures on the temperature display unit 42, and the indicator lamp may be lit to indicate the detected temperature when the corresponding temperature is reached.

[0028] The control unit 22 is configured, for example, by a computer and includes a processor 44, a storage unit 46, an input / output (I / O) unit 48, etc. The processor 44 executes a control program stored in the storage unit 46 and performs information processing such as acquiring information related to water supply control, temperature control, temperature correction, display control, etc., as well as calculations and control output. The storage unit 46 includes memory elements such as a ROM (Read-Only Memory) and a RAM (Random-Access Memory), and stores the control programs and databases. The I / O 48 is used for inputting and outputting information under the control of the control unit 22, such as acquiring temperature information from the temperature sensor 18, acquiring operation information from the hot water button 38 or the cold water button 40, extracting the control output of the hot water solenoid valve 30 or the cold water solenoid valve 32, and displaying output to the temperature display unit 42.

[0029] <Control Functions of the Control Unit 22> The control functions of the control unit 22 include a hot water production control function, a cold water production control function, a water supply control function, a temperature detection function, a display control function, and the like.

[0030] The hot water production control function receives raw water Wo in the hot water tank 8, heats this raw water Wo with the heating unit 12 to produce hot water HW, and controls this hot water HW to a constant temperature.

[0031] The chilled water production control function receives raw water Wo in the chilled water tank 10, cools this raw water Wo using the cooling unit 14 to produce chilled water CW, and controls this chilled water CW to a constant temperature.

[0032] The water supply control function includes both hot water supply and cold water supply. When supplying hot water HW, the hot water button 38 is operated, and the hot water solenoid valve 30 is opened to guide the hot water HW from the hot water tank 8 to the water supply unit 16. When supplying cold water CW, the cold water button 40 is operated, and the cold water solenoid valve 32 is opened to guide the cold water CW from the cold water tank 10 to the water supply unit 16.

[0033] The temperature detection function, when supplying water, acquires temperature information of the water W in the container 6 from the temperature sensor 18. Then, the display control function displays the acquired temperature information on the temperature display unit .

[0034] <Location of water dispenser 2 and temperature sensor 18> Fig. 2A shows the upper part of the external appearance of the water server 2. In Fig. 2A, the same parts as in Fig. 1 are given the same reference numerals.

[0035] A bottle mounting section 50 is provided on the top of the server body 49, and a raw water container 4 (not shown) is placed on this bottle mounting section 50, and raw water Wo is automatically supplied to the hot water tank 8 and the cold water tank 10. An operation panel section 20 (B in FIG. 2) is provided on the upper front surface of the server body 49.

[0036] A recess 54 is provided in the center of the front of server body 49, set back from front panel 52, and water supply unit 16 and temperature sensor 18 are disposed on the ceiling side of this recess 54. A hot water supply port 34 and a cold water supply port 36 are disposed in water supply unit 16, and the open ends of these hot water supply port 34 and cold water supply port 36 face pedestal 56.

[0037] The temperature sensor 18 is disposed between the hot water supply port 34 and the cold water supply port 36. A guard portion 58 that protects the sensor element is attached to the temperature sensor 18. The guard portion 58 prevents fogging due to the adhesion of water droplets, such as steam or splashes from the hot water HW or cold water W.

[0038] The receiving base 56 can accommodate a container 6 for supplying water W, and is equipped with a grating 60 for drainage. When supplying water, the user can pick up the container 6 and pour hot water HW from the hot water supply outlet 34 or cold water CW from the cold water supply outlet 36 into the container 6.

[0039] <Operation panel section 20> Fig. 2B shows the operation panel unit 20. In Fig. 2B, the same parts as in Fig. 1 are denoted by the same reference numerals.

[0040] A temperature display unit 42 is provided in the center of the operation panel unit 20, and on either side of the temperature display unit 42 are a hot water button 38, a cold water button 40, and a lock release button 41 in the center. The hot water button 38 displays "hot water" to indicate the type of water to be supplied, and the cold water button 40 displays "cold water" to indicate the type of water to be supplied. Normally open contacts are provided individually inside the hot water button 38 and the cold water button 40, and when the user presses one of these buttons and continues to press it, the water supply state changes to hot water HW or cold water CW.

[0041] The unlock button 41 is a switch for unlocking the locked state of the hot water button 38 and the cold water button 40. When locked, the display unit 43 emits light to indicate that the buttons are locked.

[0042] <Water supply and temperature display procedure> 3 shows an example of a process for supplying water, detecting temperature, and displaying temperature. This process is an example of a program of the present disclosure.

[0043] Initial settings are performed when power is supplied to the water dispenser 2. If the raw water container 4 is installed, raw water Wo is supplied to the hot water tank 8 and the cold water tank 10 via the valve mechanism 24, and under normal circumstances, the hot water tank 8 and the cold water tank 10 are kept full.

[0044] 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 an open state (S102), the supply of hot water HW begins, and the device enters a 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 supplied to the container 6.

[0045] When supplying water, 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, and the supply of hot water HW continues (S103).

[0046] If the hot water button 38 is OFF (YES in S104), the hot water electromagnetic valve 30 is controlled to the closed state (S105), so that the water supply is canceled (S106), and the supply of hot water HW is stopped.

[0047] When the cold water button 40 is turned on (YES in S201), the cold water solenoid valve 32 is controlled to an open state (S202), and the supply of cold water CW begins, entering a water supply state (S203). At this time, the cold water CW is guided from the cold water pipe 28 to the cold water supply port 36 and supplied to the container 6.

[0048] When supplying water, 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, and the supply of cold water CW continues (S203).

[0049] If the cold water button 40 is OFF (YES in S204), the cold water electromagnetic valve 32 is controlled to the closed state (S205), so that the water supply is canceled (S206), and the supply of cold water CW is stopped.

[0050] In these water supply controls, when the hot water solenoid valve 30 or the cold water solenoid valve 32 transitions to an open state, the system enters a temperature detection mode for the water W in the container 6 (S301). The temperature sensor 18 detects the temperature of the water W in the container 6 in a non-contact manner (S302). The temperature detection information from the temperature sensor 18 is input into the control unit 22, which calculates the temperature of the water W. The temperature detected by the temperature sensor 18 is displayed on the temperature display unit 42 (S303).

[0051] In this temperature detection mode, the control unit 22 determines whether the temperature detection mode is cancelled (S304). If the temperature detection mode is not cancelled (NO in S304), the temperature display continues (S303), and if the temperature detection mode is cancelled (YES in S304), the temperature display is cancelled (S305).

[0052] In this way, while water is being supplied to the container 6 or after it has been supplied, the temperature of the water W can be known from the temperature display on the temperature display unit 42, and if this temperature is lower than the desired temperature, the hot water button 38 is operated to add hot water HW to the container 6, and 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, thereby adjusting the temperature of the water W to the desired temperature.

[0053] <Water supply mechanism for hot water HW and cold water CW of Water Server 2> Fig. 4 shows an example of a water supply mechanism for hot water HW and cold water CW of the water server 2. In Fig. 4, the same parts as those in Figs. 1 and 2 are given the same reference numerals.

[0054] The water supply port 62 of the raw water container 4 installed in the water server 2 is connected to the valve mechanism 24. The valve mechanism 24 includes a float 64 installed in the cold water CW of the cold water tank 10, and a valve body 66 that is opened and closed by the up and down movement of the float 64. The float 64 is subjected to buoyancy from the cold water CW, and when the cold water CW is at a reference water level, it closes the valve body 66, stopping the supply of raw water Wo from the raw water container 4, but when the cold water CW falls below the reference water level, it allows water supply from the raw water container 4 until the valve body 66 closes. Raw water Wo is supplied to the cold water tank 10 in response to the supply of cold water CW.

[0055] The hot water tank 8 is supplied with raw water Wo from the cold water tank 10 side by a receiving plate 68 and a water supply pipe 70 inside the cold water tank 10 in response to the supply of hot water HW.

[0056] The heating unit 12 is composed of a heater 72. A temperature sensor 74 that detects the temperature of the hot water HW is installed in the hot water tank 8. The control unit 22 acquires detected temperature information from the temperature sensor 74 and controls the heat generation of the heater 72, thereby controlling the hot water HW in the hot water tank 8 to maintain a constant temperature.

[0057] The cooling unit 14 circulates the refrigerant from a cooling device 76, which cools the refrigerant, through an evaporator 78, and generates chilled water CW in the chilled water tank 10 by heat exchange between the refrigerant and raw water Wo. The cooling device 76 includes a compressor 80, a dryer 82, a condenser 84, a capillary tube 86, etc. The chilled water tank 10 is provided with a temperature sensor 88 that detects the temperature of the chilled water CW. The control unit 22 acquires temperature information detected by the temperature sensor 88, controls the cooling device 76, and maintains the chilled water CW in the chilled water tank 10 at a constant temperature.

[0058] <Advantages of the First Embodiment> According to the first embodiment, one of the following effects can be obtained.

[0059] (1) In the water server 2, the temperature of the water W in the container 6 can be known from the temperature display of the temperature display unit 42 during or after water is being dispensed.

[0060] (2) During or after water is being supplied, the temperature display on the temperature display unit 42 can be checked, and while checking this temperature display, the temperature of the water W in the container 6 can be easily adjusted to the desired temperature by supplying hot water HW or cold water CW.

[0061] Second Embodiment The water server 2 according to the second embodiment detects and displays the temperature of the water W from the start of water supply, and continues to detect and display the temperature of the water W for a fixed period of time after water supply is stopped. In this embodiment, the control unit 22 includes a time measurement function or timer, which measures a fixed period of time (e.g., 5 seconds) after water supply is stopped, and maintains temperature measurement and temperature display for this fixed period of time.

[0062] <Temperature detection and display procedure> 5A shows a processing procedure for detecting and displaying a temperature according to the second embodiment. This processing procedure is an example of a program of the present disclosure.

[0063] The temperature detection mode (S401), temperature detection of the water W in the container 6 (S402), and temperature display (S403) correspond to the temperature detection mode (S301), temperature detection of the water W in the container 6 (S302), and temperature display (S303) shown in FIG.

[0064] In this embodiment, it is determined whether a certain time Ts has elapsed from the point in time when both the hot water solenoid valve 30 and the cold water solenoid valve 32 are controlled to the closed state (S404). If the certain time Ts has not elapsed from this point in time (NO in S404), the temperature display continues (S403).

[0065] When a certain time Ts has elapsed since both the hot water solenoid valve 30 and the cold water solenoid valve 32 were controlled to be closed (YES in S404), the temperature display is cancelled (S405).

[0066] <Processing timing from water supply to temperature display> Fig. 5B shows a timing chart from water supply to temperature display in the second embodiment. In Fig. 5B, a indicates the water supply period, b indicates the time measurement after water supply, c indicates the temperature detection period, and d indicates the temperature display period.

[0067] As shown in B-a of Figure 5, at time t0, for example, when the hot water button 38 (or cold water button 40) is turned ON and the hot water solenoid valve 30 (or cold water solenoid valve 32) is controlled to an open state, the supply of hot water HW (or cold water CW) begins. If the hot water button 38 (or cold water button 40) remains ON until time t1, the water supply state continues from time t0 to time t1.

[0068] As shown in FIG. 5Bb, a certain time Ts is measured from time t1 when water supply is started to time t2.

[0069] 5Bc, after time t0, temperature detection of the water W poured into the container 6 begins, and this temperature detection continues until time t2. In other words, the fixed time Ts from time t1 is also a temperature detection period.

[0070] As shown in Fig. 5B-d, the temperature is displayed during temperature detection, and this temperature display continues until time t2. In other words, the temperature display period is a fixed time Ts from time t1.

[0071] <Advantages of the second embodiment> According to the second embodiment, one of the following effects can be obtained.

[0072] (1) After water is supplied to the container 6, the temperature detection and temperature display can be continued for a certain period of time (for example, about 5 seconds) after the hot water button 38 or cold water button 40 is released, thereby improving the convenience of the water server 2, such as by allowing the user to determine whether the temperature of the water W in the container 6 is the desired temperature within a certain period of time after the water is supplied.

[0073] (2) The temperature of the water W after mixing the hot water HW and cold water CW in the container 6 can be known, and water can be supplied while checking the temperature of the water in the container 6.

[0074] Third Embodiment The water server 2 according to the third embodiment has a temperature detection button on the operation panel, and detects and displays the temperature in response to an appropriate operation of the temperature detection button.

[0075] Fig. 6A is a diagram showing operation panel unit 20 according to the third embodiment, and Fig. 6B is a diagram showing a part of water server 2 according to the third embodiment. In Fig. 6A, the same parts as in Fig. 2B are given the same reference numerals.

[0076] In this embodiment, a temperature detection button 90 for detecting the temperature of the water W is provided on the operation panel unit 20, and in response to operation of this temperature detection button 90, the control unit 22 controls the temperature detection.

[0077] The function of the temperature detection button 90, such as starting temperature detection, may be assigned to the unlock button 41, so that temperature detection can be started by operating (pressing) the unlock button 41.

[0078] Fig. 6B shows a part of a water server 2 according to a third embodiment. In Fig. 6B, the same parts as in Fig. 1 are given the same reference numerals.

[0079] Operation information such as pressing the temperature detection button 90 is input to the control unit 22 and is used to control the arithmetic processing of the processor 44 via the I / O 48.

[0080] <Temperature detection and display procedure> 7 shows a procedure for detecting and displaying a temperature according to the third embodiment. This procedure is an example of a program of the present disclosure.

[0081] This processing procedure includes temperature detection mode (S501), determining whether the temperature detection button 90 has been operated (S502), detecting the temperature of the water W in the container 6 (S503), displaying the temperature (S504), determining whether the temperature detection button 90 has been released (S505), and releasing the temperature display (S506).

[0082] In the water supply control of the water server 2, when the hot water solenoid valve 30 or the cold water solenoid valve 32 transitions to an open state, the mode is changed to a temperature detection mode for the water W in the container 6 (S501).

[0083] In this temperature detection mode, the control unit 22 determines whether the temperature detection button 90 is ON (S502). If the temperature detection button 90 is ON (YES in S502), the temperature sensor 18 detects the temperature of the water W in the container 6 (S503) and acquires temperature information. The control unit 22 displays the temperature of the water W on the temperature display unit 42 (S504). While this temperature is being displayed, the control unit 22 monitors whether the temperature detection button 90 has been turned OFF (S505). Therefore, the temperature display continues until the temperature detection button 90 is turned OFF.

[0084] Then, when the control unit 22 acquires information indicating that the temperature detection button 90 is OFF (YES in S505), the temperature display is cancelled (S506).

[0085] <Advantages of the third embodiment> According to the third embodiment, one of the following effects can be obtained.

[0086] (1) During or after water is being supplied to the container 6, the temperature of the water W in the container 6 can be detected by operating the temperature detection button 90, and the detected temperature can be displayed on the temperature display unit 42, allowing the temperature of the water W to be known. Moreover, the temperature of the water W in the container 6 can be detected in real time directly below the temperature sensor 18, allowing the temperature to be known.

[0087] (2) If the temperature of the water W is lower than the desired temperature while operating the temperature detection button 90, the hot water button 38 or cold water button 40 can be operated to add hot water HW or cold water CW to the container 6, thereby adjusting the temperature of the water W to the desired temperature.

[0088] (3) Even when water is not being dispensed from the water dispenser 2, the temperature sensor 18 can be made to detect the temperature of the water W in the container 6, and the temperature of the water W can be known.

[0089] [Fourth embodiment] The water server 2 of the fourth embodiment includes display lamps 96H, 96M, and 96L in the optimum temperature display unit 94 that display multiple different recommended temperatures, and when the temperature of the water W reaches the corresponding recommended temperature, the recommended temperature is displayed by lighting up one of the display lamps 96H, 96M, and 96L.

[0090] Fig. 8A shows the operation panel of a water dispenser according to the fourth embodiment. In Fig. 8A, the same parts as in Fig. 6 are given the same reference numerals.

[0091] In the operation panel unit 20 of this embodiment, the temperature display unit 42 includes a numeric display unit 92 and an optimum temperature display unit 94. The numeric display unit 92 corresponds to the temperature display unit 42 (FIG. 1) of the first embodiment. The optimum temperature display unit 94 includes a plurality of indicator lamps 96H, 96M, and 96L. The indicator lamps 96H, 96M, and 96L are examples of indicator lamps that indicate different recommended temperatures according to the present disclosure.

[0092] In this embodiment, indicator lamp 96L lights up at a recommended temperature of, for example, 36 to 40°C for milk, etc. Indicator lamp 96M lights up at a recommended temperature of, for example, 50 to 90°C for tea (sencha), etc. Indicator lamp 96H lights up at a recommended temperature of, for example, 75 to 90°C for coffee, etc.

[0093] In this embodiment, the temperature display unit 42 uses both a numerical display unit 92 and an optimum temperature display unit 94, but the numerical display unit 92 may be omitted, leaving only the optimum temperature display unit 94, and the number of display levels for the recommended temperature on the optimum temperature display unit 94 may be four or more.

[0094] Fig. 8B shows a part of the water server 2 according to the fourth embodiment. In Fig. 8B, the same parts as those in Fig. 6B are given the same reference numerals.

[0095] The temperature display unit 42 includes a numeric display unit 92 and an optimum temperature display unit 94. The numeric display unit 92 is, for example, a segment display that displays the value of the detected temperature of the water W. The display lamps 96L, 96M, and 96H are, for example, LEDs.

[0096] The control unit 22 receives detected temperature information from the temperature sensor 18, compares the temperature of the water W with the recommended temperature, and when the temperature of the water W reaches the recommended temperature set in the indicator lamp 96L, it illuminates the indicator lamp 96L to indicate this. When the temperature of the water W reaches the recommended temperature set in the indicator lamp 96M, it illuminates the indicator lamp 96M to indicate this. Furthermore, when the temperature of the water W reaches the recommended temperature set in the indicator lamp 96H, it illuminates the indicator lamp 96H to indicate this.

[0097] In this embodiment as well, operation information such as pressing of the temperature detection button 90 is taken into the control unit 22 and is used to control the arithmetic processing of the processor 44 via the I / O 48 .

[0098] <Temperature detection and display procedure> 9 shows a procedure for detecting and displaying a temperature according to the fourth embodiment. This procedure is an example of a program of the present disclosure.

[0099] This processing procedure includes a water supply mode (S601), a temperature detection mode (S602), a temperature display (S603), a determination of the detected temperature (S604, S606, S608), lighting of the indicator lamp 96H (S605), lighting of the indicator lamp 96M (S607), lighting of the indicator lamp 96L (S609), and the like.

[0100] In the water supply control of the water dispenser 2, when the hot water solenoid valve 30 or the cold water solenoid valve 32 transitions to an open state, hot water HW or cold water CW is supplied to the container 6 (S601). During this water supply, a temperature detection mode is entered in which the temperature of the water W in the container 6 is detected (S602).

[0101] In this temperature detection mode, when the temperature detection button 90 is turned ON, the control unit 22 acquires the detection information of the water W in the container 6 detected by the temperature sensor 18 and displays the temperature of the water W on the numerical display unit 92 (S603).

[0102] In this temperature display, the control unit 22 determines whether the detected temperature has reached the recommended temperature TH (S604). If the detected temperature has reached the recommended temperature TH (YES in S604), the control unit 22 causes the indicator lamp 96H to emit light (S605).

[0103] In this temperature display, the control unit 22 determines whether the detected temperature has reached the recommended temperature TM (S606). If the detected temperature has reached the recommended temperature TM (YES in S606), the control unit 22 causes the display lamp 96M to light up (S607).

[0104] In this temperature display, the control unit 22 determines whether the detected temperature has reached the recommended temperature TL (S608). If the detected temperature has reached the recommended temperature TL (YES in S608), the control unit 22 causes the display lamp 96L to light up (S609).

[0105] During this temperature display, the control unit 22 monitors whether the temperature detection button 90 has been turned off. Therefore, the numerical display and the optimum temperature display continue until the temperature detection button 90 is turned off.

[0106] When the control unit 22 acquires information indicating that the temperature detection button 90 is OFF, the numerical display and the optimum temperature display are cancelled.

[0107] <Advantages of the Fourth Embodiment> According to the fourth embodiment, one of the following effects can be obtained.

[0108] (1) When supplying either hot water HW or cold water CW or both, when the temperature of the water W reaches the desired recommended temperature, this can be displayed on the optimum temperature display unit 94, and it can be displayed that the temperature of the water W has reached the recommended temperature set for beverages or foods such as milk, tea, or coffee.

[0109] (2) Even when hot water HW or cold water CW is added to the water W in the container 6, the temperature sensor 18 can detect the temperature of the water W in the container 6, thereby improving the convenience of the water server 2, such as by instantly displaying that the water W has reached the recommended temperature.

[0110] Fifth Embodiment

[0111] The water server 2 of the fifth embodiment is equipped with a mixed water supply section (mixed water supply pipe 100) that mixes hot water HW and cold water CW and supplies the water to the container 6, and detects and displays the temperature of the water W in the container 6.

[0112] Fig. 10 shows a water server 2 according to a fifth embodiment. In Fig. 10, the same parts as those in Fig. 1 and Fig. 6 are denoted by the same reference numerals.

[0113] In the water server 2 of this embodiment, a mixed water supply unit 98 is installed in place of the water supply unit 16. This mixed water supply unit 98 is equipped with a mixed water supply pipe 100 that merges hot water HW and cold water CW. A hot water solenoid valve 30 is installed in the hot water pipe 26, and a cold water solenoid valve 32 is installed in the cold water pipe 28. In this embodiment as well, the opening and closing of the hot water solenoid valve 30 is performed by the control unit 22 in response to operation of the hot water button 38, and the opening and closing of the cold water solenoid valve 32 is performed by the control unit 22 in response to operation of the cold water button 40.

[0114] 11A shows a mixed water supply section 98. In this mixed water supply section 98, the hot water pipe 26 and the cold water pipe 28 are joined to a mixed water supply pipe 100, which is formed with a single water supply port 102. The hot water HW from the hot water pipe 26 and the cold water CW from the cold water pipe 28 join together in the mixed water supply pipe 100, and the mixed water is supplied to the container 6 from the water supply port 102.

[0115] In this case, when the hot water button 38 and the cold water button 40 are operated simultaneously, the hot water HW and the cold water CW are mixed in the mixed water supply pipe 100 and supplied, but when only the hot water button 38 (A in FIG. 6) is operated, the hot water HW flows from the hot water pipe 26 to the mixed water supply pipe 100 and is supplied to the container 6. On the other hand, when only the cold water button 40 (A in FIG. 6) is operated, the cold water CW flows from the cold water pipe 28 to the mixed water supply pipe 100 and is supplied to the container 6. When the hot water HW and the cold water CW are supplied separately in this way, the hot water HW and the cold water CW are mixed in the container 6.

[0116] The temperature of the water W in the container 6 is detected by the temperature sensor 18, and the detected temperature is displayed on the temperature display unit 42. This temperature detection and display may be controlled by the control unit 22 based on the operation of the temperature detection button 90.

[0117] <Modification of the installation position of the temperature sensor 18> Fig. 11B shows a modified example of the installation position of the temperature sensor 18. In Fig. 11B, the same parts as in Fig. 11A are denoted by the same reference numerals.

[0118] The temperature sensor 18 may be installed at a position opposite the receiving base 56 as shown in A of Fig. 11, but may also be installed at a position intersecting the path of the mixed water, hot water HW, or cold water CW being supplied as shown in B of Fig. 11 to detect the temperature of the water W being supplied. In this case, the temperature of the water W falling into the container 6 can be detected and displayed.

[0119] <Advantages of the Fifth Embodiment> According to the fifth embodiment, one of the following effects can be obtained.

[0120] (1) The hot water pipe 26 and the cold water pipe 28 are unified into a mixed water supply pipe 100, and mixed water of hot water HW and cold water CW, hot water HW or cold water CW can be supplied from a common water supply port 102.

[0121] (2) Since the water supply port 102 is unified, it is not necessary to move the container 6 to the water supply position each time mixed water, hot water HW, and cold water CW are supplied.

[0122] (3) By installing a temperature sensor 18 at a position that intersects with the falling path of the mixed water, hot water HW, or cold water CW in the water supply, the temperature of the mixed water, hot water HW, or cold water CW before it reaches the container 6 can be detected and these temperatures can be displayed.

[0123] Sixth Embodiment The water server 2 according to the sixth embodiment changes the duty ratio of the hot water solenoid valve 30 and the cold water solenoid valve 32 in accordance with the set temperature selected by the set temperature selection button 104, and supplies water.

[0124] Fig. 12 shows a water server 2 according to a sixth embodiment. In Fig. 12, the same parts as those in Fig. 1 and Fig. 6 are denoted by the same reference numerals.

[0125] In this embodiment, the water server 2 is provided with a set temperature selection button 104 for selecting a set temperature on the operation panel 20. The set temperature selection button 104 includes an up button 106U for increasing the set temperature and a down button 106D for decreasing the set temperature.

[0126] When selecting a set temperature, the control unit 22 accepts operation of the up button 106U or the down button 106D to raise or lower the set temperature, and generates display information for the set temperature being operated and the confirmed set temperature. The temperature display unit 42 displays both the set temperature being operated and the confirmed set temperature.

[0127] The storage unit 46 stores a temperature table 108 (FIG. 13B) as an example of a database used to change the duty ratios of the hot water solenoid valve 30 and the cold water solenoid valve 32 according to the set temperature.

[0128] The up button 106U or the down button 106D includes an indicator lamp, which lights up during operation under the control of the control unit 22 to indicate the up button 106U or the down button 106D that is being operated.

[0129] <Operation panel section 20> 13A shows the operation panel unit 20 according to the sixth embodiment. The up button 106U has a display mark that indicates the upward direction of the set temperature with a triangle, and the down button 106D has a display mark that indicates the downward direction of the set temperature with an inverted triangle.

[0130] 13B shows the temperature table 108. In this temperature table 108, a set temperature section 110, a duty ratio section 112 for the hot water solenoid valve 30, a duty ratio section 114 for the cold water solenoid valve 32, a mixing ratio section 116, and the like are set.

[0131] The set temperature section 110 stores temperature information indicating the set temperature selected by operating the up button 106U or the down button 106D.

[0132] The duty ratio section 112 of the hot water solenoid valve 30 stores control information that indicates the duty ratio that indicates the opening and closing time of the hot water solenoid valve 30 corresponding to the selected set temperature.

[0133] The duty ratio section 114 of the cold water electromagnetic valve 32 stores control information of the duty ratio that indicates the opening and closing time of the cold water electromagnetic valve 32 corresponding to the selected set temperature.

[0134] The mixing ratio section 116 stores information indicating the mixing ratio of the hot water HW and the cold water CW, which is set by the duty ratio of the hot water solenoid valve 30 and the duty ratio of the cold water solenoid valve 32.

[0135] <Temperature setting or water supply procedure> 14 shows a procedure for setting a temperature or supplying water according to the sixth embodiment. This procedure is an example of a program for selecting a set temperature, displaying it, and supplying water according to the present disclosure.

[0136] This processing procedure includes mode setting (S701), selection of set temperature (S702, S703, S705, S706), temperature display (S704, S707), determination of set temperature (S708), display of set temperature (S709), setting of duty ratios of hot water solenoid valve 30 and cold water solenoid valve 32 (S710), water supply (S711), temperature detection (S712), temperature display (S713), etc.

[0137] When the water dispenser 2 is in operation or when water supply is completed, it transitions to a temperature setting mode (S701). In this hot water setting mode, when the up button 106U is pressed (S702), the temperature is incremented each time the button is pressed (S703), and the selected temperature is displayed on the temperature display unit 42 (S704).

[0138] In this hot water setting mode, when the down button 106D is pressed (S705), the temperature is decremented each time (S706), and the selected temperature is displayed on the temperature display unit 42 (S707). After the temperature selection, when a certain time has elapsed, the selected temperature is determined as the set temperature (S708), and this set temperature is displayed on the temperature display unit 42 (S709).

[0139] The duty ratios of the hot water solenoid valve 30 and / or the cold water solenoid valve 32 corresponding to the determined set temperature are retrieved from the temperature table 108 (B in FIG. 13), and these duty ratios are set in the hot water solenoid valve 30 and / or the cold water solenoid valve 32 (S710). The opening and closing of the hot water solenoid valve 30 and / or the cold water solenoid valve 32 is controlled according to these duty ratios.

[0140] When the hot water button 38 is pressed, hot water HW is supplied, and when the cold water button 40 is pressed, cold water CW is supplied according to the duty ratio (S711).

[0141] The temperature of the water W supplied to the container 6 is detected by the temperature sensor 18 (S712). Under the control of the control unit 22, the temperature display unit 42 switches from setting temperature display to displaying the temperature of the water W, and the temperature of the water W is displayed (S713).

[0142] <Water supply at the set temperature Tt> With respect to the volume M of the container 6 (for example, 200 cc), the water supply amount Mt to the container 6 is set such that Mt < M.

[0143] When the set temperature Tt is selected, in order to achieve the water supply amount Mt of the set temperature Tt for the container 6, 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.

[0144] When the hot water button 38 is pressed, the hot water solenoid valve 30 becomes open, and this open state is maintained for the duty Dh (seconds). The supply of this hot water HW is performed for the duty Dh (seconds) regardless of the pressing time of the hot water button 38.

[0145] When the cold water button 40 is pressed, the cold water solenoid valve 32 becomes open, and this open state is maintained for the duty Dc (seconds). The supply of this cold water CW is performed for the duty Dc (seconds) regardless of the pressing time of the cold water button 40.

[0146] The pressing order of the hot water button 38 and the cold water button 40 can be either. In the container 6, by supplying the hot water HW and the cold water CW, water W at the set temperature Tt can be obtained by mixing the hot water HW and the cold water CW.

[0147] Then, the temperature of the water W is detected and its temperature is displayed, and the user can know the temperature of the water W in the container 6. If necessary, after canceling the set temperature, it is possible to add more hot water HW or cold water CW to adjust to the desired temperature.

[0148] In this embodiment, the operation panel unit 20 may be provided with a mixed water supply button (for example, a mix button) for supplying a mixture of hot water HW and cold water CW, and by pressing this mixed water supply button, mixed water of hot water HW and cold water CW is supplied to obtain the selected set temperature Tt, thereby realizing the set temperature Tt.

[0149] <Advantages of the Sixth Embodiment> According to the sixth embodiment, one of the following effects can be obtained.

[0150] (1) The set temperature of the water W supplied to the container 6 can be set to any desired target temperature by the user by operating the up button 106U or the down button 106D.

[0151] (2) The set temperature being selected or after being selected can be displayed on the temperature display unit 42, allowing the user to select the set temperature while checking the temperature.

[0152] (3) Water can be supplied to the container 6 at any set temperature, and when the water supply starts, the temperature display unit 42 switches from displaying the set temperature to displaying the temperature of the water W. During or after the water supply, the temperature of the water W in the container 6 can be displayed on the temperature display unit 42, making it easy to know the temperature of the supplied water W.

[0153] In the sixth embodiment, a temperature table 108 (B in FIG. 13) is used to obtain the duty ratios for opening and closing the hot water solenoid valve 30 and the cold water solenoid valve 32, but the present disclosure is not limited to using this temperature table 108. Instead of this temperature table 108, the control unit 22 may have a function for calculating and controlling the duty ratios 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 temperatures of the hot water HW and the cold water CW. In calculating this duty ratio, the duty ratio may be calculated by a function (mathematical formula) using the set temperature and current temperature of the water W. [Example]

[0154] In the water server according to the first embodiment, when a non-contact temperature detection element 120 is used as the temperature sensor 18, the temperature characteristics of the non-contact temperature detection element 120 are corrected to improve the detection accuracy of the water W.

[0155] Fig. 15A shows a water server according to Example 1. In Fig. 15A, the same parts as in Fig. 1 are given the same reference numerals.

[0156] Temperature detection unit 118 includes non-contact temperature detection element 120 and temperature correction thermistor 122, and is installed in water supply unit 16 described above. Non-contact temperature detection element 120 is an example of temperature sensor 18, and is a functional element that detects the temperature of water W in a non-contact manner. Temperature correction thermistor 122 is an example of a temperature correction temperature sensor disclosed herein, and is installed to avoid the influence of the temperature characteristics of non-contact temperature detection element 120, and detects the temperature (ambient temperature) of the location where temperature sensor 18 is installed. Instead of temperature correction thermistor 122, a temperature correction thermistor 124 may be provided separately from temperature detection unit 118.

[0157] The temperature correction unit 126 includes a control unit 22, an amplifier unit 128, and a thermistor detection circuit 130. The amplifier unit 128 is composed of an operational amplifier or the like, and amplifies the detection signal of the non-contact temperature detection element 120 to a level that can be easily processed on the control unit 22 side.

[0158] The thermistor detection circuit 130 detects the detection signal of the temperature correction thermistor 122 and generates a signal for correcting the temperature characteristics of the non-contact temperature detection element 120 .

[0159] In this case, the control unit 22 receives the detection signal from the non-contact temperature detection element 120 and the detection signal from the temperature correction thermistor 122, and executes the temperature conversion process 132 and the temperature correction process .

[0160] The temperature conversion process 132 is a process for converting the output signal of the non-contact temperature detection element 120 into the temperature of the water W. This conversion process may use a function for converting the detection signal into a temperature value, or may convert the detection signal into a temperature value by referring to conversion data of the temperature conversion value for the detection signal.

[0161] Temperature correction processing 134 is a temperature correction processing performed when the non-contact temperature detection element 120 is affected by temperature. In this case, the detection signal of the temperature correction thermistor 122 is used to perform correction processing on the output signal of the non-contact temperature detection element 120.

[0162] As described above, the operation panel unit 20 is provided with the hot water button 38, the cold water button 40, and the temperature display unit 42. The hot water button 38 and the cold water button 40 are examples of operation means for instructing the start of temperature detection and temperature display in synchronization with the start of water supply of hot water HW or cold water CW.

[0163] The temperature display unit 42 uses an LCD (Liquid Crystal Display) or a plurality of LED (Light Emitting Diode) displays to display the detected temperature of the water W. This temperature display may be either a numerical display showing the temperature or an indicator showing the temperature range.

[0164] Regarding the temperature correction process 134, the present disclosure is not limited to processing by calculation using the control unit 22, but rather, the output signal of the non-contact temperature detection element 120 may be subjected to correction processing using an electrical circuit (not shown) outside the control unit 22, and the detected information may then be input into the control unit 22.

[0165] Figure 15B shows another water server according to Example 1, in which a temperature correction unit 136 is installed in the front stage of control unit 22 instead of temperature correction processing 134 of control unit 22. In Figure 15B, the same parts as in Figure 15A are given the same reference numerals.

[0166] The temperature correction unit 136 performs temperature correction when the non-contact temperature detection element 120 is affected by temperature. In this case, the output signal of the non-contact temperature detection element 120 is corrected using the detection signal of the temperature correction thermistor 122 at a front stage of the control unit 22, and then this output signal is input to the control unit 22.

[0167] The other configurations of Example 1 are the same as those of the above-described embodiment, and therefore the description thereof will be omitted.

[0168] <Effects of Example 1> According to this embodiment 1, when a non-contact temperature detection element 120 is used as the temperature sensor 18 that detects the temperature of the water W poured into the container 6, the temperature characteristics of the non-contact temperature detection element 120, which is affected by the ambient temperature, etc., are corrected, thereby improving the accuracy of temperature detection of the water W. [Example]

[0169] Fig. 16 shows the front of a water server 2 according to Example 2. In Fig. 16, the same parts as those in Figs. 1 and 2 are denoted by the same reference numerals.

[0170] In this second embodiment, the temperature detection unit 138 is installed at an upper position away from the water supply unit 16, and the temperature sensor 18 is built into this temperature detection unit 138. Therefore, this temperature sensor 18 detects the temperature of the water W in the container 6 in a non-contact manner, and the temperature is displayed on the temperature display unit 42.

[0171] On the front of the water supply unit 16, an indication mark 140 is provided to indicate the water supply position and the temperature detection position.

[0172] <Effects of Example 2> According to the second embodiment, one of the following effects can be obtained.

[0173] (1) The temperature of the water W can be detected from a position away from the water supply unit 16, and the influence of steam and splashes rising from the water W on the temperature detection can be avoided.

[0174] (2) The display mark 140 can guide the height and horizontal position of the container 6, and the temperature detection position can be standardized.

[0175] (3) The container 6 receiving the water can be directed toward the detection range of the temperature sensor 18 even when the temperature sensor 18 is located away from the container 6 .

[0176] (4) The detection range of the temperature sensor 18 can be easily confirmed visually, and the appropriate position and height at which the container 6 should be placed can be confirmed. [Example]

[0177] Fig. 17 shows a side view of a water server 2 according to Example 3. In Fig. 17, the same parts as in Fig. 16 are given the same reference numerals.

[0178] The temperature detection unit 138 has a light emitting element 142 installed on the back side of the temperature sensor 18, and this light emitting element 142 may emit guide light 144, which indicates the detection position and range of the temperature sensor 18, toward the receiving base 56. The position indication (spot) formed by this guide light 144 may be imaged at a recommended position on the container 6. This image position may be set at the center of the container 6 to which water is to be supplied, at the center position of temperature detection.

[0179] A laser light emitting element may be used as the light emitting element 142, and a temperature detection spot may be imaged at the induction position of the container 6 by a laser beam.

[0180] <Effects of Example 3> According to the third embodiment, one of the following effects can be obtained.

[0181] (1) The water supply position of the water W can be indicated by light, and the container 6 receiving the water can be guided to this position indication.

[0182] (2) By indicating the water supply position with light, the influence of dirt on the water supply position and temperature detection range can be avoided. [Example]

[0183] Fig. 18 shows a partially cutaway front view of a water server 2 according to Example 4. In Fig. 18, the same parts as in Fig. 16 are given the same reference numerals.

[0184] In the second embodiment, the temperature detection unit 138 is installed above the water supply unit 16, but it may also be installed inside the server main body 49. In this case, a sensor installation space 148 may be installed inside the server main body 49, and the temperature sensor 18 may be installed inside this sensor installation space 148. This temperature sensor 18 is preferably located above the hot water supply port 34 and the cold water supply port 36. The temperature detection range 150 may then be set at the opening of the container 6 (not shown).

[0185] If a protective film that does not prevent infrared rays from passing through is installed at the opening of the sensor installation space 148, it is possible to prevent the steam from the hot water HW or water W from affecting the temperature detection. Also, instead of this protective film, an infrared transmission filter that allows only infrared rays to pass through may be installed.

[0186] <Effects of Example 4> According to the fourth embodiment, one of the following effects can be obtained.

[0187] (1) Since the temperature sensor 18 is installed inside the server body 49, the degree of freedom in the exterior design of the water server 2 can be increased.

[0188] (2) The temperature sensor 18 can be protected from splashes from the water W in the container 6.

[0189] (3) By installing a cover or an infrared-transmitting filter on the opening of the sensor installation space 148, the temperature sensor 18 can be protected and the window that receives infrared rays can be easily cleaned. In addition, the degree of freedom in exterior design can be increased. [Example]
