The conventional coffee brewer is the same as the coffee brewer of Embodiment 1 described later in FIG. 1 except for the heating control means 8, and other configurations are the same. Therefore, referring to FIG. Will be explained. Water pipe 3
The water in the water container 1 that has flowed into the chamber is heated by the heater 4a, pushed up in the water pipe 3 by the vapor pressure at the time of boiling, and is discharged to the extraction unit 2. Further, the heater for heating and keeping the temperature of the heat insulation container 6 containing the coffee liquid extracted by the extraction unit 2 is also used as the heater for extraction heating 4 a for heating water and sending it to the extraction unit 2. The temperature of the coffee liquid in the heat insulating container 6 is kept warm by controlling the temperature by the temperature detecting means 5 attached to the heating means 4. In such a conventional coffee brewing machine, in order to reduce the concentration of the coffee liquid extracted into the heat insulation container 6, the coffee is usually slowly extracted over time. for that purpose,
By heating the heater 4a by the duty control energization or the phase control energization by the heating control means 8, the heating power is reduced and the interval of intermittent hot water supply from the water pipe 3 to the extraction part 2 is extended.
After that, when all the water in the water container 1 is heated and discharged to the extraction section 2, the temperature of the heating means 4 rapidly rises. When the temperature of the heating means rises to a temperature at which it is judged that the hot water supply has ended, the heating control means 8 stops the energization of the heater 4a.

The higher the temperature of the water put in the water container 1, the higher the stable temperature of the heating means 4 during the heat extraction. In such a case, the first embodiment
If the timing for switching to continuous energization is set as a threshold value based on an absolute value, the timing for switching to continuous energization will change even if the same amount of water is extracted. The finished temperature of the coffee liquid at the end changes.

ことができる。In this embodiment, the condition for switching to the continuous energization is judged by the temperature rise rate judgment of the detected temperature.
Even if the temperature of the water in the water container 1 is changed, the timing of switching to continuous energization is almost constant, so the heating time for reheating by continuous energization is stable, and the stable temperature of the coffee liquid at the end of hot water drinking is stable. It can be adjusted to the optimum temperature range.

5 cups and 680 ml when heated by adding water at 0 ° C,
The detected temperatures of the respective heating means 4 when water of 20 ° C. is added and heated are shown. The larger the amount of water put in the water container 1, the longer the time for extracting water by heating. Usually, if the time for heating and extracting water is long, the time for heating the coffee liquid already extracted in the heat retaining container 6 also becomes long, and the coffee temperature before the additional heating is increased. If the reheating time by continuous energization is the same time, the finished temperature will be higher and will be the upper limit of the optimum temperature range of 82 ° C to 85 ° C at the time of drinking.
Therefore, in the present embodiment, the first predetermined time is set to 5 minutes so that the reheating heating by continuous energization is performed when the finished temperature of the coffee liquid at the end of hot water supply is 320 ml or less, which is relatively low. is doing. As a result, the finished temperature of the coffee liquid can be set to about 83.0 ° C., which is the center of the appropriate temperature range of 82 ° C. to 85 ° C. at the time of drinking for both 2 cups and 5 cups.

り温度を変えることができる。The operation of the heating control means 8 in the coffee brewer configured as described above will be described with reference to the flowchart of FIG. First, high temperature or low temperature is selected by the finished temperature selecting means (step 1). When heating is started, the heating control means 8 energizes the heater 4a with a duty of a cycle of 12/16 seconds (step 2). Then, when the water in the water container 1 is exhausted and the temperature of the heating means 4 starts to rise and the temperature detected by the temperature detection means 5 becomes 80 ° C. or higher which is the first predetermined temperature, if the finished temperature selection is high. The heater 4a is switched to continuous energization to continue heating (step 3a). If the final temperature selection is low, the heater 4a is continuously energized with a duty cycle of 12/16 seconds (step 3b). After that, when the temperature detected by the temperature detecting means 5 becomes 125 ° C. or higher, which is judged as the hot water supply end temperature, the energization is ended (step 4). Thus, when the selection by the finished temperature selection means is instructed, the temperature in the temperature detection means exceeds the first predetermined temperature and the continuous energization is switched until the hot water supply end temperature is reached and the coffee in the heat retaining container is switched. By heating and reheating the liquid, it is possible to change the finished temperature of the coffee according to the taste of the user.

FIG. 12 is a correction value table of the hot water supply end temperature according to the temperature detected by the temperature detection means 5 at the start of heating. The standard is ambient temperature of 20 ° C and temperature range 3 of 15 ° C.
When the temperature is up to 25 ° C and the temperature is set to 125 ° C without correction, the final temperature of the coffee liquid when 320 ml of 2 cups is aimed at 83 ° C. For example, the detected temperature at the start of heating is 10 ° C
If so, since it is the region 2, the hot water supply end temperature is set to the initial value 12
The correction value + 5.5 ° C is added to 5 ° C to obtain 130.5 ° C.
The measured values with and without correction in each region are almost as intended as shown in FIG. Here, the temperature of 35 ° C. or higher in the region 5 is uniformly set to −6.5 ° C., but when the coffee brewer is continuously used, the heating means 4 is not sufficiently cooled and the detected temperature at the start of heating is 100. It may be over ℃,
The correction stops working. This embodiment is effective when the temperature of the heating means 4 is the same as the ambient temperature, and if a dedicated temperature detecting means for faithfully detecting the ambient temperature is provided,
