This ultrasonic wave propagates in the air, is totally reflected on the surface of the effervescent beverage 52 in the beverage cup 53 due to the difference in acoustic impedance, propagates in the opposite direction, and is received by the ultrasonic transceiver 54.

The received ultrasonic signal 102 is amplified by the receiver 55, and a narrow band amplifier 56 for removing noise is further added.
And the large amplitude received ultrasonic signal 103 is obtained.
By the way, the received ultrasonic signal 102 includes not only the echo from the surface of the effervescent beverage 52 to be originally measured, but also unnecessary echoes from the upper part and the edge of the cup, which is a kind of base noise. Become. However, since the level of the unnecessary echo is known, the large-amplitude received ultrasonic signal 103 is binarized by the comparator 58 that uses the value larger than the unnecessary echo level as the setting threshold, and the error due to this noise is generated. Detection can be avoided.

Further, the enable signal 120 is supplied from the system controller 50 to the comparator 58, but this signal does not malfunction due to the reverberation echo of the transmission, and it is ensured that only the received wave from the surface of the beverage containing the sparkling beverage is received. It responds by acting as a window. The F / F 59 is the output 104 of the comparator 58.
And timing signal 10 from the system controller 50
From 0, a transmission / reception interval pulse signal 105 having a pulse width from ultrasonic transmission to reception is formed.

Assuming that the transmission / reception interval is t and the sound velocity in the air is C, the distance D from the airborne ultrasonic transceiver 54 to the surface of the sparkling beverage 52 is given by D = t * C / 2 Since the distance from the bottom surface of the beverage cup 53 to the airborne ultrasonic transceiver 54 is known, the sparkling beverage 5
The injection height of 2 will be known. Note that such calculation and temperature correction in the air are performed by the spouting apparatus main control unit 60.

FIG. 3 is a block diagram showing the second embodiment, and FIG. 4 is a waveform diagram for explaining the operation. The system controller 50 has the function of generating the timing signal 100 for detecting the height of the beverage to be injected, as in the case of FIG. 1, and the transmitter 51 generates a single transmission pulse signal 101 by this timing signal 100, and the sparkling beverage is generated. The ultrasonic transmitter / receiver for air 54-1 arranged on the upper portion of the beverage cup 53 in which 52 is being poured is excited to emit ultrasonic waves. This ultrasonic wave propagates in the air and reaches the surface of the sparkling beverage 52 in the beverage cup 53. The surface of the sparkling beverage 52 during injection is not flat and changes with time in waves, and the sound waves totally reflected by the surface of the sparkling beverage 52 are reflected in various directions. Therefore, an aerial ultrasonic transmitter / receiver 54-1 arranged on the axis of the beverage cup 53 and this pair of reception-only receivers arranged at symmetrical positions having a predetermined angle with respect to the axis. The airborne ultrasonic wave receivers 54-2 and 3 are respectively received.

The installation angles of the aerial ultrasonic transmitter / receiver 54-1 and the aerial ultrasonic receivers 54-2, 5-3 are such that the aerial ultrasonic transmitter / receiver 54-1 and the aerial ultrasonic receiver 54-2, 3 are installed. Let α be the directivity angle of ±, with respect to the axis of the beverage cup 53
It is desirable to set α °. Received ultrasonic signal 102-1
~ 3 are amplified by the receivers 55-1 to 5-3, and further amplified by the narrow band amplifiers 56-1 to 5-3 for removing noise,
Large-amplitude ultrasonic wave reception signals 103-1 to 103-3 are obtained. here,
As in the case of FIG. 1, the received ultrasonic signals 102-1 to 102-3 include unnecessary echoes from the upper portion, the edge, etc. of the cup in addition to the echoes from the surface of the sparkling beverage 52 to be originally measured. This is a kind of base noise, and has various levels depending on the installation angle and position. However, since the level of this unnecessary echo is known as described above, a value larger than the unnecessary echo level is set as the set thresholds 1, 2, 3
By binarizing the large-amplitude received ultrasonic wave signals 103-1 to 103-3 by the comparators 58-1 to 58-3, it is possible to avoid erroneous detection due to this noise.

An enable signal 120 is supplied from the system controller 50 to the comparators 58-1 to 58-3. This signal does not malfunction due to the reverberation echo of the transmission, and the received signal from the surface of the beverage containing the sparkling beverage is received. It plays a role as a window so that it can respond only to the situation. Outputs 104 of comparators 58-1 to 58-3
-1 to 3 are ORed by an OR circuit 61,
The logical sum output signal 106 (the shortest binarized reception signal with the shortest transmission / reception interval) is obtained. The F / F 59 forms a transmission / reception interval pulse signal 105 having a pulse width from transmission to reception of ultrasonic waves from the logical sum output 106 of the OR circuit 61 and the timing signal 100 from the system controller 50. The ultrasonic sensor from which the pulse signal 105 is obtained can be known by monitoring the binarized signals 104-1 to 104-3.

Assuming that the transmission / reception interval is t and the speed of sound in the air is C, the distance D from the aerial ultrasonic transmitter / receiver 54-1 or the aerial ultrasonic receivers 54-2, 3 to the surface of the sparkling beverage 52 is: , D = t * C / 2. From this, in order to obtain the height H with respect to the axis of the beverage cup 53, the aerial ultrasonic transceiver 54-1 or the aerial ultrasonic receiver 54-1 from which the shortest binarized signal was obtained.
If the angle with respect to the −2 and 3 axes is β, then H = D / cos β. From the bottom of the beverage cup 53 to the ultrasonic element 5
Since the distance to 4 is known, the injection height of the sparkling beverage 52 will be known.

FIG. 5 is a block diagram showing the third embodiment, and FIG. 6 is a waveform diagram for explaining the operation. this is,
3 shows a modified example of FIG. 3, in which an ultrasonic element for both transmission and reception is eliminated and an ultrasonic transmitter 54 dedicated to transmission and ultrasonic receivers 62-1 to 62-3 dedicated to reception are provided. 6
2-1 is arranged on the axis of the beverage cup 53, and the ultrasonic receivers 62-2, 3 are characterized in that they are arranged at symmetrical positions with a certain angle with respect to this axis. Further, the distance D from the ultrasonic receivers 62-1 to 62-3 to the surface of the sparkling beverage 52.
Is roughly expressed as D = t * C / {1 + 1 / cosβ}. Others are almost the same as those in FIG. 3, and therefore FIG. 6 showing the operation is also substantially the same as FIG.

FIG. 7 is a block diagram showing the fourth embodiment, and FIG. 8 is a waveform diagram for explaining the operation. The system controller 50 has a function of generating a timing signal 100 for detecting the height of the beverage infused.
00 causes the transmitter 51 to generate a single transmitted pulse signal 101, and the beverage cup 5 to which the sparkling beverage 52 is being poured.
The ultrasonic transmitter / receiver 54 for air located at the upper part of 3 is excited to emit ultrasonic waves. This ultrasonic wave propagates in the air,
The surface of the sparkling beverage 52 in the beverage cup 53 is reached.
Since the surface of the sparkling beverage 52 during injection is not flat but wavy and changes every moment, the sound waves totally reflected by the surface of the sparkling beverage 52 are reflected in various directions as described above. Is the street.

This reflected wave is received by an aerial ultrasonic transmitter / receiver 54 arranged on the axis of the beverage cup 53. After the reception sound wave signal 102 is amplified by the receiver 55, the amplification factor variable amplifier 6 that can further change the amplification factor automatically
Amplified by 3. The output signal 107 is a double-wave rectifier 64.
Is rectified by the both waves by the signal, and the signal 108 is guided to the first sample hold circuit (S / H) 65, and the system controller 5
The signal 110 held for a period set by the first sampling signal 109 given from 0 is supplied to the peak detector 66 in the next stage, and the maximum value of the received wave is held here. That is, the detection of the surface of the sparkling beverage 52 is set as the sample period, and the maximum value during the sample period is held.

Second sample hold circuit (S / H) 67
Operates with the second sampling signal 112 given from the system controller 50 and holds the maximum value 110 held by the S / H 65 during the next detection period. The held maximum value 113 is compared with the preset value 114 preset in the setter 68 in the comparison / amplifier 69, and when it is lower than the preset value, the amplification factor of the variable amplification factor amplifier 63 Is supplied to the amplification factor variable amplifier 63, and the automatic gain control signal (AGC signal) 115 for increasing the value is set to be low. Since such AGC control is performed every time the timing signal 100 is generated from the system controller 50, even if the surface of the sparkling beverage 52 undulates, the amplification factor can be changed by the AGC signal. Signal 107 input to comparator 58
The maximum level of is constant and a stable received signal can be obtained. Since the other points are the same as in the case of FIG. 1, the details are omitted.

FIG. 9 is a block diagram showing the fifth embodiment, and FIG. 10 is a waveform diagram for explaining the operation. The continuous oscillator 70 constantly oscillates at the resonance frequency ω0 of the ultrasonic element 54, and its continuous wave 116 is transmitted to the mixer 71, the system controller 50, and the gate 72.
The system controller 50 synchronizes with the continuous wave 116,
Gate signal 11 for several wavelengths that determines the emission period of ultrasonic waves
7 is applied to the gate 72, and the burst wave signal 118 is generated by the gate 72. Since the burst wave signal 118 is applied to the transmitter 51, a sound wave of several wavelengths is emitted from the ultrasonic element 54 for both transmission and reception, propagates in the air, and reaches the surface of the effervescent beverage 52 in the beverage cup 53. Will be done.

By the way, the surface of the sparkling beverage 52 being poured is not flat, but is moving at a certain speed V. When the ultrasonic wave element 54 for both transmission and reception receives the sound wave totally reflected by the surface having the velocity V, the received signal 10
The frequency of 2 becomes ω0 + ωd due to the Doppler effect.
This is amplified by the amplifier 73 and transmitted to the mixer 71.
The mixer 71 plays a role of obtaining a product of the output signal 119 of the amplifier 73 and the continuous wave 114. That is, Asi
The product of n (ω0 + ωd) t and Bsin (ω0) t is (1/2) * A * B * {cos (2ω0 + ωd) t-c
os (ωd) t} and decomposed into a low pass filter (LPF) of the next stage.
When only the frequency ωd component is selected and extracted by 74, (1/2) * A * B * cos (ωd) t is obtained. Thus, only the reflected signal from the moving beverage surface is extracted.

By the way, the output signal (Doppler signal) 121 of the LPF 74 also includes an unnecessary signal due to noise of an electronic circuit, a weak external vibration, etc. This unnecessary signal is a kind of base noise, but is known in advance. Therefore, the comparator 58 having a threshold value greater than the unnecessary level binarizes the signal obtained by amplifying the Doppler signal 121 to avoid erroneous detection due to this noise. Subsequent processing is the same as that in FIG.
