Description

  The present invention relates to a drinking machine, and more particularly to a drinking machine that can store different liquid amounts inside a drinking machine by changing the height of the liquid level inside the drinking machine.

  As a conventional drinking machine, for example, an apparatus including a main body, a hot water tank, a liquid level sensor, a fresh water tank, and a heater is known. The main body and the hot water tank are communicated with each other by a pipe line, and the liquid inside the hot water tank enters the inside of the main body through the pipe line, and further, the main body and the hot water tank are communicated by the communication pipe. The liquid level of the tank is kept at the same height. The liquid level sensor is installed inside the main body, and the liquid level sensor is used to detect the liquid level inside the main body, so that the liquid level of the hot water tank is in a low liquid level state. The liquid in the raw water tank will be replenished up to the hot water tank, and the liquid level of the hot water tank will continue to be maintained at a high liquid level, and the heater Is used to heat the liquid inside the hot water tank.

  In addition, as a liquid level sensor provided in a conventional drinking machine, for example, in the new model No. 296054 in the Republic of China, a floating ball is provided in a space mainly composed of a main body and a support, and the main body and the support The configured space and the water tank of the drinking water are formed so as to communicate with each other. Further, a magnet is fixed to the side of the floating ball, a magnetic spring type switch is provided inside the storage tank on the side of the main body, and the liquid inside the main body is in a low liquid level state. At some point, the magnetic spring type switch activates the water supply unit (eg, water supply member) and continues to replenish the liquid to the inside of the water tank, and the floating until the liquid inside the main body is in a high liquid level state. The magnet located on the side of the ball attracts the magnetic spring switch to turn it off, thereby preventing the water supply unit from continuing to supply water. As a result, there is a water tank of the drinking water device that keeps a high liquid level state (see, for example, Patent Document 1).

  Further, referring to FIG. 5, a conventional beverage apparatus includes a liquid level sensor 91 and a low water level switch 92. The liquid level sensor 91 is a sensor mainly for limiting the upper limit position of the liquid level, and the low water level switch 92 is a sensor for mainly warning that the liquid level has reached the lower limit position. The liquid level sensor 91 is provided at the upper end of the storage tank 93, and the low water level switch 92 is provided at the bottom inside the fresh water tank 94. The storage tank 93 communicates with the hot water tank 95 of the drinking water machine 9. The liquid level sensor 91 is electrically connected to a water supply member (water stop valve) 96, and the low water level switch 92 is electrically connected to a heater 97. The liquid level sensor 91 at the upper end issues a start signal by detecting that the hot water tank 95 is full, and controls to turn off the water supply member 96 based on this start signal (that is, stop the flow of water). Control). In addition, the water supply member 96 supplies water in the raw water tank 94 to the hot water tank 95 in the ON state. That is, since the liquid level sensor 91 at the upper end does not detect the full water level when the hot water tank 95 is at a lower water level, the water supply member 96 is controlled to be turned on. Water is supplied from the tank 94 into the hot water tank 95. Then, when the low water level switch 92 detects the low water level, the heater 97 is controlled to turn off the heating of the hot water tank 95, and the hot cooking of the heat tank 95 can be avoided. There is something like that.

When the limit switch 41b can sense the position of the floating ball 42, it sends out one signal to the control unit 5, Control unit 5 can control from Kyosui member 32 may stop water supply.

  The temperature detector 12 detects the liquid temperature inside the hot water tank 1, and when the liquid temperature drops, the temperature detector 12 heats the heater 11 against the liquid inside the hot water tank 1. Therefore, the liquid temperature inside the hot water tank 1 can be maintained. Furthermore, by controlling the opening and closing of the heater 11 using the low water level switch 311, it is possible to avoid the heater 11 from cooking with respect to the hot water tank 1.

  The amount of liquid in the hot water tank 1 can be set according to the user's usage demand, and the user can selectively select the liquid level adjustment keys 51a, 51b, 51c according to the usage demand. Since the water supply member 32 can import the liquid to be replenished into the hot water tank 1 and can continue to import it so that it can be stored up to the predetermined liquid level. Since the vessel 11 can heat only the amount of liquid required by the user, energy can be saved.

  FIG. 3 is an explanatory diagram according to the second embodiment of the drinking water machine of the present invention. Referring to FIG. 3, in the second embodiment, the liquid level sensor 4 is provided with only one limit switch 41 and one floating ball 42. A sliding groove 23 is provided on the outer peripheral surface of the storage tank 2, and the limit switch 41 is provided in the sliding groove 23. Since the limit switch 41 can move inside the sliding groove 23, it is possible to adjust that the limit switch 41 is in a predetermined position. In this way, the user can arbitrarily adjust the position where the limit switch 41 detects the liquid amount according to the required liquid amount, thus providing the user with the freedom to selectively change the liquid amount. be able to. Since the method for starting and cutting the water supply member 32 in the second embodiment is the same as that in the first embodiment, the description is omitted here.

  As described above, according to the drinking machine of the present invention, the user can know the amount of liquid required by the plurality of liquid level indicator lines 21, and one of the liquid level adjustment keys 51a, 51b, The limit switches 41a, 41b, 41c can control the water level to be replenished up to the hot water tank 1 by switching 51c or moving the position of the limit switch 41 to the position of the liquid amount to be sensitive. Therefore, the amount of liquid stored in the hot water tank 1 can be changed, and heating of the entire liquid in the hot water tank 1 can be avoided, so that heating can be performed quickly. And can reach the effect of saving energy.

  The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof. Accordingly, the preferred embodiments described herein are illustrative and not limiting.
