Definitions

  • This invention relates to an apparatus for making ice blocks comprising a frame, a hollow body fixedly mounted on this frame and having downwardly projecting parts, means for circulating refrigerating fluid through said hollow body, means for circulating heating fluid through said hollow body, a small tray, a mechanism bringing said small tray from an uppermost position around the above- said projecting parts to a lowermost position and conversely, a water supply line that opens into said tray, means that open and close said water supply line, and elements that control the said means and the said'mechanism in such a way that : the means for circulating the refrigerating fluid through the body are in operation while - the tray is in its uppermost position, the mechanism brings the tray from its uppermost position into its lowermost position when ice has formed on the projecting parts,the means for circulating heating fluid through the body come into operation after ice has formed on the projecting parts, and the water supply line is opened after ice has formed on the projecting parts.
  • the elements that control the mechanism and the means for circulating the fluids through the hollow body comprise e.g. a microswitch which is closed when a stirrer meets with resistance offered by the ice that has formed on the above named projecting parts, which then are in the tray that is occupying its uppermost position.
  • closing of such microswitch causes to stop the circulation of the refrigerating fluid and to start the circulation of the heating fluid and causes also the action of the mechanism that first brings the small tray from its uppermost position into its lowermost position and then from its lowermost position into its uppermost position.
  • closing of the microswitch brings about the opening of the water supply line so that water flows into the tray.
  • the mechanism that brings the tray from an uppermost to a lowermost position and conversely comprises a motor-speed reducer whose power is sufficient to bring about the upward and downward movement of the tray.
  • the amount of water added to the tray is determined by a float, which closes the supply line as soon as enough water has been added.
  • the use of a float is avoided by allowing the added amount of water exceeding the required amount to flow away, but in these embodiments opening of the water supply line has to be controlled by a time switch, a programmator or any analogous mechanism.
  • the motor-speed reducer bringing about the movement of the tray, the float mechanism and the time switch or the analogous mechanism determining the opening period of the water supply line, are elements that complicate the apparatus for making ice blocks and strongly influence the cost price.
  • the present invention provides an apparatus that obviates the need of these elements.
  • the mechanism bringing the tray from its uppermost into its lowermost position and converselv consists of :
  • the apparatus according to the present invention essentially a downward movement of the tray is brought about by the fact that water is flowing into the tray when the ice blocks have been formed, and an upward movement is brought about by the fact that water is flowing away out of the tray being in its lowermost position.
  • the apparatus has such a mechanical suspension of the tray that in its lowermost position it forms an angle with the horizontal plane different from that formed in its uppermost position.
  • the mechanical suspension consists of at least two brackets or arms, which on the one hand are hingedly connected to the tray and on the other hand are hingedly connected to the frame, the four pivots forming a quadrangle, which is no parallelogram.
  • one of the brackets or arms bears a mercury switch, which in the lowermost position of the tray interrupts an electric circuit, which interruption closes the water supply line.
  • the apparatus represented in the figures 1 tc comprises a frame, which is integral with a bottom scale 1.
  • the shaft 2 is rotatably mounted and to this shaft 2 a motor-speed reducer 3 is suspended.
  • a hollow body bearing downwards projecting parts 5 is fixedly mounted on this frame. These downwards projecting parts 5 form hollow blocks, which are interconnected. Through this body and consequently through the blocks a refrigerating fluid as well as a heating fluid can be circulated.
  • a small tray 6 can be brought from the uppermost position represented in solid line in figure 1 to the lowermost position represented in dotted line in the same figure in a way that is detailedly described hereinafter.
  • Various elements that cooperate with the tray 6 have been represented in figure 1 in solid line in the position they are occupying when the tray 6 is at the top. They have been represented in dotted line when they are in the position they are occupying when the tray 6 is in its lowermost position. Just as the tray they have been indicated in this second position with the same reference numeral completed with a dash.
  • the tray 6 surrounds the hollow blocks 5.
  • the paddles 4 that are fixedly mounted on the shaft 2 can move between the hollow blocks 5.
  • the shaft 2 forms stirrers between the hollow blocks 5.
  • the motor-speed reducer 3 drives shaft 2 but this can result therein that the shaft 2 rotates in the frame as well as that the motor-speed reducer 3 rotates around the shaft 2, which then remains fixed.
  • the tray 6 is hingedly mounted between the ends of a U-shaped bracket or arm 10.
  • the pivots of the tray 6 with respect to this U-shaped arm 10 have been indicated by the reference numeral 11.
  • Upon rising and falling the tray 6 is moving between the legs of the U-shaped arm 10, which is mounted in the frame in two pivots 12.
  • An arm 7 is hingedly connected to the tray 6 in the pivot 8.
  • This arm 7 is fixedly attached to a shaft 9, which is bearing-supported in the frame. With respect to said frame the shaft 9 thus constitutes a pivot for the arm 7.
  • the arms 7 and 10 form a quadrangle, which is however no parallelogram.
  • This quadrangle is such that the tray 6 in its uppermost position forms with the horizontal plane an angle different fromthat formed in its lowermost position.
  • an opening 35 has been left. This opening may be adjustably executed so that the speed at which the water is flowing through this opening is adjustable.
  • the difference between the angles that are formed by the tray 6 in the uppermost and in the lowermost-position is such that water can flow away out of the tray through the opening 35 in the lowermost position, whereas in the uppermost position this opening 35 is above the water level.
  • the arm lO which is hingedly connected to the tray 6 and the frame, extends beyond the pivot 12 with the frame.
  • This extension bears a disc-shaped counterweight 13, which is adjustable around a center of rotation 36, which in its turn does not coincide with the center of gravity 37 of said disc. The importance of this adjustment is explained below
  • the tray 6 When the tray 6 is in its uppermost position it comprises a bearing plate 14, which is able to collect the ice blocks when they are released from the fixed hollow blocks 5.
  • the bearing plate 14 is mounted to a bearing arm 15, which is fixed on the shaft 16, which in its turn is bearing-supported in the frame. Past the shaft 16 the bearing arm 15 is extended with an arm 17 whose end carries a counterweight 18.
  • the bearing plate 14 passes from the position drawn in solid line to the position drawn in dotted line.
  • the loose ice blocks laying on the bearing plate 14 slide down from it and fall into the fixed bottom scale 1 in which an opening has been left (not represented) through which the ice blocks fall into a container (not represented) placed under the bottom scale.
  • the tray 6 catches the bearing plate 14 so that as soon as the tray 6 has again reached its uppermost position the bearing plate 14 again touches the bottom of the tray 6.
  • a water supply line 19 discharges above the tray, irrespective of whether said tray is in its uppermost or in its lowermost position.
  • the supply line 19 is fixed with respect to the frame.
  • a cock 20 has been mounted, which is controlled by a solenoid 32.
  • the arm 10 carries a mercury switch 25, which depending upon the wiring it contains, may be either a simple switch opening and closing a circuit or a change-over switch.
  • the mercury switch 25, the microswitch 21, the voltage supply 24 and the solenoid 23 of a'relay are connected in series.
  • the relay controls the contacts 26, 28 and 29, which are open when the solenoid 23 is not energized, and the contact 27, which is. closed when the solenoid 23 is not energized.
  • the solenoid 23 being energized, the contacts 26, 28 and 29 are thus closed and the contact 27 is thus open.
  • the contact 26 allows the passage of the supporting current, which holds the solenoid 23 energized until the circuit comprising the solenoid 23 is interrupted.
  • the contact 27 is in series with the motor of the motor-speed reducer 3 and on the other hand it is in series with a motor 30 of the fan of the refrigerating . mechanism.
  • This refrigerating mechanism represented in figure 4 consists of a circuit for the refrigerating liquid comprising a continuously working.compressor 39, a condenser 40, a capillary line 41, and an evaporator 42.
  • Said capillary line 41 maintains the pressure difference between the condenser 40 on the one hand and the evaporator 42 on the other hand.
  • the hollow body with the hollow blocks 5 belongs to the evaporator 42.
  • the motor 30 drives the fan (not represented in figure 4), which is mounted in front of the condenser 40. When the motor 30 and hence the fan are in action, refrigerating air is blown over the condenser 40.
  • a bypass 43 comprising a valve 31 directly connects the exit 38 of the compressor 39 to the entrance 45 of the evaporator 42.
  • the valve 31 is mostly closed if the motor 30 of the fan of the condenser 40 is in operation, and said motor 30 in most cases is inoperative when the valve 31 is open.
  • valve 31 is open and in addition the fan does not blow refrigerating air over the condenser, the gas leaving the exit 38 of the compressor 39 is directly led to the evaporator 42 through the bypass 43 so that a heating fluid is then flowing through the evaporator, which indeed does not function as an evaporator at that moment.
  • the contact 28 is disposed in series with the solenoid of the valve 31.
  • this solenoid When this solenoid is in a closed electric circuit, the voltage supply being connected to the terminals 24, the valve is open so that heating fluid is being circulated through the hollow body with the hollow blocks 5.
  • the valve 31 When the electric circuit is open the valve 31 is in its closed position so that refrigerating fluid is circulated through the hollow body with the hollow blocks 5.
  • the contact 29 is disposed in series with the solenoid 32, which upon being energized opens the cock 20.
  • the contact 28 and the solenoid of the valve 31 on the one hand and the contact 29 and the solenoid 32 of the cock 20 on the other hand are not directly connected to the terminals 24 but are connected indeed by the help of a thermostatic switch 33. At its low temperature said switch makes the connection to the contact 28. This is the normal position of the switch 33, which only passes into the other position if heating fluid has flown through the hollow blocks for some time. In the said other position the thermostatic switch makes the connection to the contact 29.
  • the starting contact 22 is connected in parallel to the microswitch 21.
  • the mercury switch 25 is closed when the tray 6 is in its uppermost position and is opened when said tray is falling and thus also the arm 10 is changing its position.
  • the mercury switch 25 When the tray 6 is in its uppermost position and not enough ice has been formed yet on the hollow blocks 5 so as to impede the blades 4 in their movement, the mercury switch 25 is thus closed and the microswitch 21 is open.
  • the solenoid 23 of the relay is thus not energized; only the contact 27 is closed.
  • the motor 3 is driving the shaft 2 and the motor 30 of the fan of the refrigerating mechanism is in operation.
  • the solenoid of the valve 31 of the bypass 43 As the contact 28 is open, the solenoid of the valve 31 of the bypass 43 is not energized so that the fluid leaving the exit 38 of the compressor is led to the evaporator 42 via the condenser 40 and the capillary line 41. So, refrigerating fluid is flowing through the hollow blocks 5.
  • Opening of the contact 27 has the effect that the motor-speed reducer 3 is not driven any longer and that the motor 30 of the fan of the refrigerating mechanism becomes inoperative.
  • the microswitch 21 is opened again, but meanwhile the function of the latter has been taken over by the contact 26, which maintains the supporting current through the solenoid 23 of the relay.
  • the thermostatic switch 33 is in the low temperature position, thus is not yet closing the circuit over the contact 29 and the solenoid 32, but it does close the circuit over the contact 28 and the solenoid of the valve 31 of the bypass 43.
  • heating fluid is pumped through the hollow blocks 5, so that ice blocks are released from the hollow blocks 5 and fall onto the bearing plate 14.
  • the thermostatic switch 33 is reaching a temperature that is sufficiently high to make this switch interrupt the connection to the contact 28 and to make the connection with the contact 29.
  • the solenoid of the valve 31 thus does not continue to be energized any -longer.
  • the byyess 43 is thus sealed and the exit 38 of the compressor again thus remains only in contact with the evaporator 42 condenser 40 and the capillary line 41, but the refrigerating mechanism is not working effectively as yet since the motor 30 of the fan of the condenser 40 remains inactive as long as the contact 27 is open.
  • the solenoid 32 is energized whereby the cock 20 is opened. So, water is flowing through the line 19 into the tray 6. As a result thereof the tray 6 becomes heavy enough so as to pass from its uppermost to its lowerpost position.
  • the already released ice blocks thereby are sliding from the bearing plate 14 into the bottom scale 1 and thence into the container. Together with the tray 6 the arm 10 changes its position, which opens the mercury switch 25.
  • thermostatic switch 33 switches from the contact 29 to the contact 28, but this remains without effect because the contacts 29 and 28 are open.
  • the filled tray allowing in its lowermost position to flow away water through the opening 35 is gradually loosing weight. After enough water has flown away through the opening 35, the tray and its contents have lost enough weight so as to be raised again by the counterweight 13.
  • the blocks 5 are then back in the water. Ice can again be formed and the cycle can restart.
  • the mercury switch 25 is again closed but this has no further effect as long as the microswitch 21 is open.
  • the electric wiring diagram of figure 6 differs from the electric wiring diagram of figure 5 by the following features :
  • the mercury switch 25 closes the circuit over the solenoid 32 and the contact 29 when the tray is in its uppermost position and closes the circuit over the solenoid of the valve 31 when the tray 6 is falling and thus also the arm 10 is changing its position.
  • the thermostatic switch 33 is closed at low temperature and is only opened when the temperature exceeds a threshold value as a result of the flow of the heating fluid.
  • the microswitcb 21 When the tray 6 is in its uppermost position and not yet enough ice has been formed around the hollow blocks 5 so as to impede the movement of the paddles 4, the microswitcb 21 is open. So, the solenoid 23 of the relay is not energized. only the contact 27 is closed. The motor of the motor-speed reducer 3 is driving the shaft, the motor 30 of the fan of the condenser 40 remains in operation, and since, among other things as a result of the fact that the contact 28 is open, the solenoid of the valve 31 is not energized, the bypass 43 is closed and the refrigerating fluid normally flows through the evaporator 42 and in consequence through the hollow blocks 5. In this way ice gradually forms around the hollow blocks 5. When the ice layer has grown to a certain thickness it obstructs the passage of the paddles 4 and thus impedes t' rotation of the shaft 2 in the frame.
  • the thermostatic switch 33 is in the lower temperature position and keeps the circuit closed over the solenoid 23.
  • the contact 29 closes the circuit over the solenoid 32, which opens the cock 20.
  • the mercury switch 25 indeed is in the position wherein it closes the circuit over the solenoid 32 and the contact 29.
  • water is flowing through the line 19 in the tray 6.
  • the tray becomes heavy enough so as to pass from its uppermost into its lowermost position.
  • the arm lO changes position, which makes the mercury switch 25 to change over from the connection to the solenoid 32 to the connection to the solenoid of the valve 31.
  • the circuit of the solenoid 32 is intenupted thereby so that the cock 20 is closed and no water is added to the tray 6 any more.
  • the thermostatic switch 33 interrupts the circuit of the solenoid 23 of the relay.
  • the contact 26 of the supporting circuit of the solenoid 23 is interrupted.
  • the contact 27 is again closed, which again engages the motor-speed reducer 3 driving the shaft 2 and also puts the motor 30 into operation.
  • the contacts 28 and 29 are re-opened.
  • the opening of the contact 28 the energizing of the solenoid of the valve 31 fails, so that the refrigerating mechanism again circulates refrigerating fluid through the hollow blocks 5.
  • the opening of the contact 29 has no effect because the mercury switch 25 closes the circuit not over the solenoid 32 of the cock 20 but over the solenoid of the valve 31 and the solenoid 32 was thus not energized any longer.
  • the amount of water that has to leave the tray in the lowermost position does not depend upon the applied electric wiring diagram and can be approached as follows according to figure 9.
  • ⁇ g has to be equal to the volume occupied by the immersed bodies multiplied by the density of the water.
  • the increase in volume proceeding from the formation of ice the volume of the immersed bodies consists of the volume occupied by the hollow blocks, the volume occupied by the bearing plate and the volume occupied by the stirrer.
  • the weight thus calculated still has to be added the weight that is required to compensate for the frictional losses in the pivots.
  • the apparatus according to the figures 1 and 2 can be built without stirrers 4, shaft 2, motor-speed reducer 3 and microswitch 21.
  • a change-over switch 34 is, e.g., a second mercury switch.
  • the change-over switc 34 closes a circuit when the tray 6 is in its uppermost position and closes another circuit as soon as the tray 6 ; has fallen very slightly. If the change-over switch 34 is a mercury switch on one of the arms 7 and 10, a very slight drop of the tray 6 has to be sufficient for making the merc switch turn.
  • the ice formation around the hollow blocks 5, which is accompanied by an increase in volume, is sufficient for causing a slight drop of the tray 6 and this slight drop ha to be sufficient for making the change-over switch 34 turn.
  • the first circuit has to be open and the second circuit has to be closed after the turn.
  • the electri wiring diagram according to figure 8 relates to such an embodiment.
  • the change--over switch 34 is in sries with the motor 30 of the fan of the refrigerating mechanism and on the other hand it is in series with the solenoid of the valve 31 of the bypass 43 and with the sole 32 controlling the opening of the cock 20.
  • the change-over switch 34 closes the circuit of the motor 30.
  • the change - o switch 34 closes the other circuit.
  • the solenoid 32 is in series with the mercury switch 25, and the solenoid 32 and the mercury switch 25 on the one hand as well as the solenoid of the valve 31 of the bypass 43 on the other hand are in series with the thermostatic switch 33.
  • Said thermostatic switch 33 just as in the other embodiments is at the end of the evaporator so that the thermostatic switch 33 only opens or again closes if the flow of the refrigerating fluid through the evapcrat 24 has ceased relatively long ago or was back on process again relatively long ago.
  • the difference between the temperature of closing and the temperature of opening of the thermostatic switch is relatively large.
  • the mercury switch 25 is closed when the tray 6 is in its uppermost position and requires a rotation through a larger angle for opening than the angle that is needed for making the change-over switch 34 to turn.
  • the circuit of the motor 30 of the fan of the condenser 40 of the refrigerating mechanism is closed.
  • the other circuit is open so that the solenoid 32 is not energized, the cock 20 is closed and no water supply is taking place.
  • the circuit of the solenoid of the valve 31 of the bypass 43 is interrupted too, so that this solenoid is not energized and the bypass is closed. So, the refrigerating mechanism is circulating refrigerating fluid through the hollow blocks 5 . and ice is being formed around these blocks.
  • the tray 6 slightly falls as a consequence of the increase in volume resulting therefrom. This makes the change-over switch 34 to turn so that the circuit of the motor 30 is interrupted. The fan is not blowing cool air over the condenser 40 of the refrigerating mechanism any longer. At the same time the circuits of the solenoid of the valve 31 and of the solenoid 32 controlling the cock 20 are closed. The valve 31 thus opens the bypass 43 so that the fluid leaving the compressor 39 is directly led to the evaporator 42, which is then not acting as an evaporator any longer. Heating-fluid is thus flowing through the hollow blocks 5. Water is flowing through the cock 20 into the tray 6.
  • the mercury switch 25 interrupts the circuit of the solenoid 32. Thereby the cock 20 is closed. When the tray has come down and the cock 20 is closed, water is flowing from the tray through the opening 35.
  • the size of the opening is such that only enough water has flown away out of the tray 6 for allowing said tray to rise back if the thermostatic switch 33 is already opened.
  • the thermostatic switch 33 opens so that also the circuit of the solenoid of the valve 31 is interrupted.
  • the bypass 43 is closed thereby and no longer heating fluid but again refrigerating fluid is led from the condenser 40 to the evaporator 42.
  • the hollow blocks 5.thus receive again refrigerating fluid before the tray 6 rises again.
  • tray goes u p again so that first the mercury switch 25 is again closed, which has no consequence as yet since the thermostatic switch 33 is open, and thereupon the change-over switch 34 comes back into the position wherein it closes the circuit of the motor 30.
  • the fan of the condenser 40 is then driven again and the normal refrigerating action can anew take place.
  • thermostatic switch 33 has to close again with such a delay that this switch is still open when upon rising of the tray 6 the mercury switch 25 is again closed, since otherwise upon rising of the tray from the closure of the mercury switch 25 on until the interruption of thecircuit of the solenoid 32 off the change-over switch 34, a certain amount of water would flow into the tray, which would make the amount of water in the tray too large and would result into an advanced fall of said tray.
  • the tray rises and falls by a mere addition and flowing away of water and that no further motor-speed reducer is needed in order to set the tray in movement.
  • the apparatus is completely composed of simple mechanical and electric elements that hardly can be deranged and hence guarantee a reliable operation.
  • the refrigerating mechanism represented therein may be replaced by another refrigerating mechanism.
  • the change-over switch may be of another type. This change-over switch has not to be mounted directly on one of the arms 7 and 10 either.
  • the change-over switch may be connected to the tray by means of an indirect mechanical transmission.
  • the embodiment according to figure 8 may be combined with the use of a stirrer 4, a shaft 2, a motor-speed reducer 3 and a micro-switch 21.
