Description

Description: TECHNICAL FIELD The present invention relates to an electric coffee brewer having a coffee bean crushing function.

(Prior Art) Conventionally, in a coffee brewer having a coffee bean crushing function and a drip function, the maximum rated bean amount showing the coffee bean crushing ability of the coffee brewer is indicated in an instruction manual or the like. However, when you want to drink a strong coffee, or when you want to add coffee beans without paying attention to it, you often put more coffee beans than the maximum rated amount and grind them. In terms of performance, the load on the motor is greater than that set at the time of design, or if the amount of beans is too large and the motor is locked, the coil of the motor will burn out if it is energized. On the other hand, in order for the coffee beans to be crushed normally, the crushing chamber needs a coffee bean portion and other space where the coffee beans can be freely released.

From this, in the conventional coffee brewing machine having a coffee bean crushing function, the maximum rated bean amount showing the coffee bean crushing ability is described in detail in the instruction manual or the like, or a caution is given, or on the side wall of the raw material crushing chamber, By marking the height when the maximum rated bean amount was entered, we have made sure that no more than the maximum rated bean amount can be placed.

(Problems to be Solved by the Invention) However, in the conventional electric coffee brewer, the consciousness of the amount of coffee beans is consciously limited on the user side so as not to crush beans having a maximum rated bean amount or more. There was a problem that the conscious act could not be forced each time, and it often happened that more than the maximum rated bean amount was crushed.

The present invention has been made in consideration of the above-mentioned conventional problems, and provides a coffee brewing machine which eliminates the occurrence of crushing of coffee beans exceeding the coffee crushing ability of the coffee brewing machine without depending on the conscious action of the user. Especially.

(Means for Solving Problems) In order to solve the above problems, the present invention provides a raw material crushing chamber equipped with a drive motor in a main body, and having a built-in cutter that is rotationally driven by the drive motor, and the raw material. The raw material pulverizing chamber has a lid that covers the upper portion of the pulverizing chamber and has a dome portion above the upper peripheral edge of the raw material pulverizing chamber, a tank that stores water, a heater that heats the water in the tank, and a filtration chamber. The upper peripheral height of the crushing chamber is set so that the amount of coffee beans placed in the upper peripheral edge of the crushing chamber becomes the maximum amount of coffee crushing capacity of the drive motor.

(Operation) With the above configuration, even if the user does not intentionally adjust the amount of beans, the amount of beans that exceeds the coffee bean crushing capacity does not enter the raw material crushing chamber, and the load when crushing coffee beans at the time of design is exceeded. Load is not applied to the motor for grinding coffee beans.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. (1) is the main body, a tank for storing water (2)
And a heater (not shown) that heats the water in the tank (2)
The water in the tank which is heated by the heater is sent to the water heater (3). (4) is the main body (1)
It is a motor equipped inside.

(5) is a crushing filtration chamber consisting of a crushing chamber (6) and a filtration chamber (9) .The crushing chamber (6) contains a cutter (7), and a perforated plate (8) is provided on a part of the peripheral wall. ) have. The filtration chamber (9) is arranged side by side so as to communicate with the crushing chamber (6) through a perforated plate (8). The cutter (7) has a crushing filter chamber (5) in the main body (1).
It is rotated by the motor (4) when it is attached. (1
Reference numeral 0) is a lid that covers the upper part of the crushing filtration chamber (5). The lid (10) is provided with a runner (11) so that the hot water discharged from the hot water supply device (3) passes through the runner (11) and is dripped into the filtration chamber (9). . In addition, the crushing chamber (6) side of the lid (10) is the dome part (12)
When the crushing chamber (6) is fully filled with coffee beans, a space corresponding to the dome portion (12) is formed above the upper edge. In the crushing chamber (6), the height of the upper rim is set so that the amount of beans filled up to the upper rim reaches the maximum rated bean amount that indicates the coffee bean crushing capacity of the coffee brewer.

Therefore, by setting the height of the peripheral edge of the upper part of the grinding chamber so that the amount of beans in a cup of coffee beans is the maximum rated bean amount, it is impossible to put more beans than the maximum rated bean amount. It becomes possible and the user does not need to consciously adjust the bean amount. Also, since the lid that covers the grinding chamber has a dome portion so that a space can be formed above the upper peripheral edge of the grinding chamber, the beans can be freely released into the upper space even when the coffee beans are put into the grinding chamber. It is also possible to prevent the motor in the crushing chamber from being locked and the motor being burnt out.

(Effects of the Invention) As is clear from the above description of the embodiments, the present invention is designed so that the amount of coffee beans placed in the upper peripheral edge of the raw material crushing chamber is the maximum amount of coffee beans crushing capacity. Since the height is set and the lid that covers the upper part of the raw material crushing chamber has a dome portion above the peripheral edge of the upper part of the raw material crushing chamber, the amount of beans that exceeds the coffee bean crushing capacity may enter. No more crushing coffee beans than the coffee crushing capacity of the electric coffee brewer.
Even when coffee beans are put into the upper rim of the raw material crushing chamber, the dome portion is above the upper rim, so that the beans can be freely released into the upper space and the cutter in the crushing chamber can be locked. It disappears and its industrial effect is great.
