Description

  The present invention relates to a water supply apparatus and a water supply method for supplying water containing sherbet-shaped ice, and more particularly to a water supply device and a water supply method capable of managing the temperature of a mixture obtained by mixing water with other substances and stirring.

  When water is mixed with other substances, especially solids, to produce a dough, and the final product is produced from the dough, it is necessary to control the temperature of the dough depending on the product. The strictness of temperature control varies depending on the product.For example, ready-mixed concrete can be kneaded in the temperature range necessary for sufficient reaction to proceed without cracking, while bread dough etc. can be used for proper fermentation. In order to make it occur, more accurate temperature management is required.

In order to strictly control the kneading temperature of the dough, it is necessary to supply feed water at an appropriate temperature according to the ambient temperature, the heat capacity of the material, and the temperature. For this reason, depending on the atmosphere or material temperature, it may be necessary to supply water of 0 ° C. or lower (ie, supercooled water) in calculation. In view of this, an apparatus for producing cold water that can supply cold water close to 0 ° C. has been devised (see Patent Document 1, etc.). The cold water manufacturing apparatus described in Patent Document 1 supplies and mixes ice particles and water to be cooled in a container, passes the mixture through a static mixer, melts the ice particles, and the temperature of the cold water is 0. When the temperature reaches around ℃, the valve is opened and cold water is sent to the load side.

  However, a high degree of control mechanism is required to stably produce cold water of about 4 ° C. or lower under normal pressure. In particular, when manufacturing cold water or supercooled water near 0 ° C., for example, if a refrigerant or the like is used, ice grows in the heat exchanger, which may cause poor circulation or blockage of the pipe, preventing the water temperature from reaching the target temperature. Become. In order to prevent this, advanced controls and mechanisms are required, resulting in large and expensive equipment.

  Further, in the method of producing cold water by mixing ice with water, there is a problem that the temperature of the supplied water is not uniform due to a spatial bias in the water temperature.

  Furthermore, although it may be necessary to mix supercooling water at 0 ° C or lower, the method using cooling water supplies supercooling water at a temperature of about several degrees Celsius below the freezing point when using a cooling device having a mechanism of a considerably high altitude. In some cases, it is difficult to produce a dough having a desired temperature.

  This invention is made | formed in view of the said prior art example, and it aims at providing the water supply apparatus and water supply method which can manufacture stably the water of required temperature or the water of substantially required temperature stably.

  In order to achieve the above object, the present invention comprises the following arrangement.

  With such a configuration, water that reaches the target temperature by absorbing the target heat quantity can be obtained with a simple configuration even if it is supercooled water or water at a temperature that is difficult to stably supply near the freezing point. Can be supplied.

  According to the present invention, it is possible to supply sherbet-like water in which water and shaved ice are mixed, and even when supercooled water is required, it is possible to stably supply thermally equivalent water. it can. Furthermore, by making the ice to be mixed into a sherbet, the fluidity of the ice is improved, and there is no possibility of damaging the mixer device using the water. In addition, the ice contained in the supplied water is easily melted and can be swollen in the same mixing time as when only water is mixed with other materials. Further, since the temperature of the water itself may be such that it can be manufactured with a relatively simple configuration, the supercooled water can be substantially supplied with a simple configuration.

<Configuration of water supply device>
FIG. 1 shows an external view of a water supply apparatus according to the present invention. FIG. 1 (B) shows the appearance of a water supply unit alone. It is necessary to supply water and ice to a cold water tank, a hot water tank, and a shaved ice device provided in the water feeder 101. For this reason, the water supply to each tank is not performed manually but is configured to be directly performed from a water receiving facility (not shown) via a pipe or the like. An ice maker may also be provided in the shaved ice device. In this case, water supply to the ice maker is also performed from the water receiving facility. Water supplied from the water feeder is discharged from the drain port 101d. In addition, as shown to FIG. 1 (B), the lid | cover 101e which can be opened and closed is provided in the upper part of the water supply apparatus 101, and an inside can be wash | cleaned. Water can be supplied manually by opening the lid 101e.

  FIG. 1A is a diagram illustrating a usage state of the water supply device 101. The water feeder 101 is arranged side by side with the mixer 102, and in this state, the discharge port 101 d is located above the stirring bowl 103 of the mixer 102. Water discharged from the water supply outlet 102 is supplied into the bowl 103. Of course, the discharge port 101d is arranged so as not to contact the rotating blade member for stirring of the mixer. In use, the necessary temperature is measured by the temperature sensors 101a, 101b, 101c at the tip of the probe extending from the water supply body. The temperature sensor 101b is inserted into the flour 104, which is the main ingredient of bread, and measures its temperature. The temperature sensor 101c is fixed around the bowl 103 and measures its temperature. The temperature sensor 101a is used to measure the temperature of a secondary material or the like that greatly affects the temperature at which the dough is crushed. Although there is only one in the figure, as many temperature sensors are prepared as there are sub-materials to be measured. Note that the temperature sensor 101a may be used to measure the environmental temperature where the auxiliary material is placed, such as the temperature inside the refrigerator. In this way, the temperature of the refrigerated material can be measured collectively.

  FIG. 2 is a diagram illustrating an example of the internal structure of the water supply device 101. However, the arrangement of main members is described in an easy-to-see manner, and the casing, support members, control circuit, wiring, temperature sensor, and the like are omitted. In practice, the pump, compressor, and the like can be arranged at the lower part of the tank or the like to reduce the bottom area of the apparatus, but this is not taken into consideration in the figure.

  In FIG. 2, hot water and cold water are stored in a hot water tank 201 and a cold water tank 202, respectively. The temperature of hot water and cold water may vary depending on room temperature. Hot water is hotter than cold water and may be heated and supplied depending on the temperature of the material other than water, room temperature, etc., so this temperature is not particularly determined, and the temperature of the supplied water (lower limit temperature) To a maximum temperature (upper limit temperature) according to the heating capacity of the heater 201b. The cold water tank 202 is provided with an evaporator 205 of a cooler. With this cooler, the cold water is cooled to about 5 ° C., for example, and the temperature is maintained. The cooler has a normal structure, and the refrigerant liquefied through the compressor 206 and the condenser 207 cools the water through the receiver 208 and the evaporator 205. In both the hot water tank 201 and the cold water tank 202, temperature sensors 201a and 202a monitored by a control unit (not shown) are provided in the tanks, respectively, and the temperature of the stored water can be measured. These temperature sensors can also be used to maintain a constant water temperature during cooling and heating, but this temperature control mechanism is a known technique, and will not be described here.

  Water in the hot water tank 201 and the cold water tank 202 is discharged by pumps 209 (hot water pump) and 210 (cold water pump), respectively. The pipe connected to the hot water pump 209 branches into a hot water supply pipe 209a and a circulation pipe 209d. Each pipe is provided with electromagnetic valves 209b and 209c. Therefore, when the hot water pump 209 is driven with the valve 209b opened and the valve 209c closed, the hot water is supplied to the mixing tank 203 through the water supply pipe 209a. When the hot water pump 209 is driven with the valve 209b closed and the valve 209c opened, the hot water is supplied to the hot water tank 209 through the circulation pipe 209d and circulates.

  The same applies to the cold water tank 210. The pipe connected to the cold water pump 210 branches into a cold water supply pipe 210a and a circulation pipe 210d. Each pipe is provided with electromagnetic valves 210b and 210c. Therefore, when the cold water pump 210 is driven with the valve 210b opened and the valve 210c closed, the cold water is supplied to the mixing tank 203 through the water supply pipe 210a. When the cold water pump 210 is driven with the valve 210b closed and the valve 210c opened, the cold water is supplied to the cold water tank 210 through the circulation pipe 210d and circulates.

  In this way, the water in each tank can be poured into the mixing tank 203 through the hot water pump 209 feed pipes 209a and 210a. Each solenoid valve is configured such that when water is not supplied from the hot water tank 209 and the cold water tank 210 to the mixing tank 203, water is circulated in the tank, and when supplied, water is supplied to the mixing tank. , Appropriately as described above.

  The lower structure of the mixing tank 203 has a mechanism for discharging water in the tank (not shown in FIG. 2). Water in the mixing tank 203 is taken from a water intake pipe 213a at the bottom of the tank by a stirring pump 213, poured from the upper part of the tank, and stirred. Each pipe, particularly the water supply pipes 209a and 210a, is preferably provided with a check valve for preventing a backflow from the mixing tank and a drain valve for drainage.

  An ice breaker (shaved ice device) 204 driven by a motor 204b is provided on the upper part of the mixing tank 203. In addition, an opening is provided on the upper surface of the mixing tank 203 so that shaved ice is supplied from the ice breaker 204 into the tank. The opening may be always open, but may be configured to be closed except during the supply of shaved ice so that the molten water of ice falling from the ice breaker 204 does not enter the mixing tank. The ice breaker 204 is electric in this embodiment, and its operation is controlled by the control unit. The mixing tank 203 is provided with a drain port 101d, and water adjusted to a desired temperature (referred to as feed water) is supplied from the drain port 101d to the mixer 102. The supply of ice to the ice breaker 204 and the supply of water to the hot water tank 201 and the cold water tank 202 are directly supplied from the water receiving facility via the water purifier. Although not shown in FIG. 2, the mixing tank 203 is provided with a heater and a cooler so that the temperature of the liquid charged in the mixing tank 203 can be finely adjusted and maintained. Has been. Furthermore, the mixing tank 203 may also be provided with a temperature sensor, thereby measuring the temperature of its contents.

  Since the hot water tank 201, the cold water tank 202, and the mixing tank 203 all need to maintain the temperature of the water stored therein, they may be formed of a highly heat-insulating material or covered with a heat insulating material. desirable. In FIG. 2, the refrigerant conducted to the cold water tank 210 is passed through an evaporator 205 provided on one surface of the tank. However, the refrigerant itself is not cooled by the refrigerant, and the freezing point is lower than that of water and is toxic. Very low substances, such as propylene glycol, can also be used as brine (indirect refrigerant) for cooling. In this case, the cold water tank is doubled, and the outer tank is filled with brine, and the brine is cooled by an evaporator to cool the inner tank, that is, the original cold water tank. In this way, freezing in the cold water tank can be prevented and uniform cooling can be achieved. Each tank is provided with an opening for cleaning, but is in a sealed state in normal use.

  FIG. 3 shows a cross-sectional view of the mixing tank 203. A piston 301 that can move up and down along the tank inner wall is provided in the tank. The bottom surface of the piston 301 is parallel to the ground contact surface of the water supply, and the upper surface is a slope that is low on the drain outlet 101d side and high on the side facing it. The piston 301 is provided with holes to which the water supply pipes 209a and 210a connected to the hot water tank 201 and the cold water tank 202 and the intake water pipe 213a for agitation are connected. The water supply pipes 209 a and 210 a and the water intake pipe 213 a are made of a flexible material so that at least a part thereof can follow the vertical movement of the piston 301. The piston 301 moves up and down by moving the shaft 306 attached to the lower portion thereof by a drive unit 307 using a motor 308 as a power source.

  In order to prevent water leakage from the gap between the inner wall of the tank 203 and the piston 301, a bellows frame 309 is provided in the gap between the piston 301 and the mixing tank 203. The bellows frame 309 is attached to the portion along the outer periphery of the piston bottom surface and the outer periphery of the tank bottom so as to maintain watertightness by adhesion or the like, and is folded when the piston 301 is lowered and stretched when the piston 301 is raised. To prevent water leakage from the bottom.

  A state where the piston 301 is raised to the top is shown by a dotted piston 301 ′. In this state, the water in the mixing tank 301 is discharged from the discharge port 101d. Even water mixed with shaved ice can be discharged from the drain port 101d by the inclination of the upper surface of the piston 301.

  The mixing tank 203 is mounted on a weight sensor (weight measuring device) 305 that can measure the entire mixing tank by structural members 302, 303, and 304 such as support columns. The weight value measured by the weight sensor 305 is input as a digital value to a control unit (not shown). Therefore, the weight of the contents in the mixing tank 203 can be measured by calibrating the weight sensor 305 so that the measured value becomes 0 when the mixing tank 203 is empty.

<Principle of water formulation>
Before explaining the water supply control procedure, it is first explained what principle the composition of water components (hot water, cold water, ice) to be blended in bread dough is determined. Bread dough is manufactured by mixing flour, which is a main material, with a secondary material according to the type of bread to be manufactured, adding water to the flour, and kneading with a mixer. The kneaded dough must be kept in a certain temperature range so that the fermentation proceeds moderately in order to allow the dough to lay and ferment for a certain period of time. Therefore, the temperature of water added to the material is determined in consideration of the hydration reaction due to the mixing of water and the generation of heat due to mixing of the mixer. And the water of the determined temperature or the ice water equivalent to the water of the temperature is manufactured by mixing warm water, cold water, and ice as a component.

For this purpose, first, the temperature of water to be mixed with flour or the like is determined by the following procedure. The input parameters are as follows: In addition, about the value set by a constant and an operator, the head of the name was shown in the capital letter.
(1) For the main material (flour), its temperature tf, weight wf, specific heat Cf
(2) About the auxiliary material, its temperature ts, weight ws, specific heat Cs
(3) About blended water, its weight ww, specific heat Cw
(4) Atmospheric temperature ta
(5) Temperature increase rate Tu of the fabric during production due to chaos
(6) Time of chaos
(7) Rising temperature T.

  What should be obtained from these input parameters is the target water temperature t. Of these, the temperature is measured by each temperature sensor. The rate of temperature rise due to chaos (for example, the temperature rise per unit time for a dough of unit weight) Tu is generated by frictional heat, hydration reaction, etc., and is desirably obtained experimentally using a mixer to be used. The rate of temperature rise cannot be determined uniformly. This is because it changes depending on the weight of the material put into the mixer and the rotational speed of the mixer. In a general mixer, speed switching can be performed in two stages, low speed and high speed. In the two-stage speed switching, the temperature increase rate is switched to two stages of Tu1 and Tu2 according to the rotation speed. For example, if the rotation speed of the mixer is switched over five stages, the temperature increase rate is switched to five stages of Tu1, Tu2, Tu3, Tu4, and Tu5 according to the rotation speed. Further, the rate of temperature rise varies depending on the weight that is mixed at a certain rotational speed. Therefore, here, the temperature increase rate fluctuating due to these various factors is collectively described as the temperature increase rate Tu.

  The specific heat of the material also needs to be measured in advance if it is not commonly known. As other constants such as the specific heat Cw of water, values generally used can be used. Further, the weight ws of the auxiliary material, the weight ww of the water, the chaos time Time, etc. can be uniquely determined according to the type of bread if the weight of the main material (hereinafter referred to as the charged amount) wf is designated. Therefore, for example, a table in which the values of the weight of the secondary material ws, the weight of water ww, and the time of chaos time are registered in the RAM 402 or ROM 403 using the bread type and the feed amount wf as input parameters, or is necessary. By downloading according to the above, those values can be given from the type of bread to be produced and the dough weight. The rising temperature T is determined in advance depending on the type of bread or regardless of the type of bread.

Now, assuming that the total weight of the dough to be fed is Wd, the temperature tb in the thermal equilibrium state generated by mixing the materials from the above parameters is
tb = ((tf * wf * Cf) + (ts * ws * Cs) + (tw * ww * Cw)) / ((wf * Cf) + (ws * Cs) + (ww * Cw))
It can be asked. In the formula, “*” means multiplication. Since the value obtained by adding the temperature rise (Tu * Time * Wd) due to the mixing of the mixer to the temperature tb should rise to the temperature T,
T = tb + (Tu * Time * Wd). That is,
T = ((tf * wf * Cf) + (ts * ws * Cs) + (t * ww * Cw)) / ((wf * Cf) + (ws * Cs) + (ww * Cw)) + (Tu * Time * Wd)
It becomes. From these equations, the target water temperature t is
t = ((T- (Tu * Time * Wd)) * ((wf * Cf) + (ws * Cs) + (ww * Cw))-((tf * wf * Cf) + (ts * ws * Cs ))) / (ww * Cw) ... (Formula 1)
Can be obtained as Furthermore, if this formula 1 is prepared for each type of bread, and the weight ws of the auxiliary material, the weight ww of water, and the chaos time Time are expressed as a function of the weight of the main material (amount charged) wf for the type of bread
t = ((T- (Tu * Time (wf) * Wd)) * ((wf * Cf) + (ws (wf) * Cs) + (ww (wf) * Cw))-((tf * wf * Cf) + (ts * ws (wf) * Cs))) / (ww (wf) * Cw)
It becomes. Since the dough weight Wd is the total weight of the charged amount, the water amount, and the auxiliary material, the input parameters excluding the constant are the bread type, the charged amount wf, the flour temperature tf, and the auxiliary material temperature ts. That is, if the type of bread, the amount of feed wf, the flour temperature tf, and the auxiliary material temperature ts are specified, the water temperature can be obtained.

  As described above, if the temperature increase rate corresponding to the five stages of rotation speed is Tu1, Tu2, Tu3, Tu4, Tu5, and the chaos time by each rotation speed is T1, T2, T3, T4, T5. , T = tb + ((Tu1 * T1 + Tu2 * T2 + Tu3 * T3 + Tu4 * T4 + Tu5 * T5) * Wd). In addition, when the temperature increase rate Tu1, Tu2, Tu3, Tu4, Tu5 varies depending on the weight, the temperature increase rate using the weight and the rotational speed, which are experimentally obtained in advance, as parameters are stored in a RAM or ROM as a table. Save it. Then, the temperature increase rate corresponding to the weight and the number of rotations is obtained from the table, the rising T is calculated, and the target temperature t can be obtained with higher accuracy. If the temperature increase rate corresponding to the two-stage rotation speed is Tu1 and Tu2, and the chaos time by the respective rotation speeds is T1 and T2, then T = tb + ((Tu1 * T1 + Tu2 * T2) * Wd).

Also, more accurate results will be obtained by considering the temperature drop of the dough depending on the chaos time and the ambient temperature. For example, when the temperature decrease rate (value per unit weight / unit time) of the fabric in the environment of the ambient temperature ta is Tra,
t = ((T-((Tu + Tra) * Time * Wd)) * ((wf * Cf) + (ws * Cs) + (ww * Cw))-((tf * wf * Cf) + (ts * ws * Cs))) / (ww * Cw) ... (Formula 1 ')
It becomes. Here, if the temperature decrease rate Tra is actually measured while changing the ambient temperature ta, it is also stored in, for example, the RAM 402 or the ROM 403 as a table using the ambient temperature ta (or further, the charged amount wf) as an input parameter. be able to. In that case, the temperature decrease rate tra can be obtained by searching the table from the ambient temperature ta.

  The above equation is an equation for determining the water temperature based on a very simple model. In order to obtain a constant dough temperature by combining various values using flour temperature, auxiliary material temperature, atmosphere temperature, and dough weight as parameters. The water temperature obtained experimentally can be registered in the table as a function of the parameter, and the water temperature and the water amount (weight) can be obtained from these values.

Next, in order to produce water having the determined water temperature t and weight ww, the amounts of cold water, hot water, and shaved ice as components of the water are determined. If the target water temperature is equal to or higher than the temperature of cold water (water in the cold water tank), water of the target temperature can be created by mixing cold water and hot water (water in the hot water tank) or heating the hot water. . When mixing cold water and warm water, cold water temperature twc, cold water weight wc, warm water temperature twh, warm water weight wh (= ww-wc),
wc = (t * ww-twh * ww) / (twc-twh) ... (Formula 2),
wh = ww-wc = (twc * ww-t * ww) / (twc-twh)… (Formula 3)
It becomes.

If the target water temperature t is equal to or lower than the temperature twc of the cold water, shaved ice is mixed with the cold water to lower the temperature of the cold water, and the absorption of heat due to the temperature increase of the water below the freezing point is replaced by the heat of ice melting as ice water. . Assuming that the specific heat of water is 1 (cal / gram / K) and the heat of melting of ice is Hm (cal / gram), the amount of heat absorbed by 0 ° C. ice during melting is the same amount of water as −Hm ° C. water. Is equal to the amount of heat absorbed when the temperature rises to 0 ° C. That is, from the viewpoint of heat absorption, 0 ° C. ice can be said to be equivalent to the same amount of water at −Hm ° C. Therefore, if the cold water temperature twc, the cold water weight wc, the ice temperature ti, the ice weight wi (= ww−wc), and the specific heat of water and ice are Cw and Ci, respectively,
t * cw * ww = twc * cw * wc + (ti * ci-Hm) * (ww-wc)
Is established. If wc is moved to the left side,
wc = ww * (t * cw-ti * ci-Hm) / (twc * cw-ti * ci + Hm) (Formula 4)
It becomes. For wi,
wi = ww-wc = ww * (t * cw-twc * cw) / (ti * ci-twc * cw-Hm) (Formula 5)
It becomes. The unit of temperature in Equations 4 and 5 is ° C. (Celsius). In this embodiment, it is desirable to use 0 ° C. ice in order to prevent inconvenience such as ice sticking to the delivery system. By configuring in this way, it is not necessary to consider the temperature rise and specific heat of ice, and the term of ti * ci in Equations 4 and 5 can be deleted to simplify the calculation.

  Control of water supply is realized by supplying cold water, hot water, and ice to a mixing tank based on the above principle, mixing them, and supplying them to a mixer. The configuration of the control unit for realizing the control will be described below.

<Configuration of water supply control>
In FIG. 4, the block diagram of the control part which controls a water feeder is shown. The CPU 401 controls the entire water supply device 101 by executing a program 402a stored in the ROM 402 and driving a motor based on input data from various sensors or the like. The RAM 403 stores input / output parameters 403a and the like, as well as various data necessary for control. The parameters stored in the parameter area 403a of the RAM 403 are as follows.

Secured. In addition, an area for storing the kneading time Time, the finishing temperature T, the water weight ww, and the auxiliary material weight ws specified from the code bc indicating the designated bread type and the preparation amount wf is also secured.

In this table, values obtained empirically are registered. In addition, a mixing | blending (recipe) is represented by the weight ratio of each material, and the weight of an auxiliary material is determined from the preparation amount and the said mixing | blending. Each identified value is stored in RAM. Here, regarding the amount of the material, the weight corresponding to the charged amount is stored in the RAM.

  The operation panel 410 is a panel for the operator to perform operations. In addition to an instruction to start water supply, the operation panel 410 has values set by the operator's intention, such as a code bc indicating the type of bread and the amount of bread dough wf. Used for input etc.

Each temperature sensor is connected to the IO interface 407 via AD converters 408a to 408g. The temperature measured by the temperature sensor is transferred to the CPU 401 as a digital value and stored in the RAM 403. The meaning of the temperature detected by each temperature sensor is described below as follows.
(1) Temperature sensor 101a: measures the auxiliary material temperature ts.

<Combination calculation process>
FIG. 5 is a control procedure executed by the control unit of FIG. 4, particularly the CPU 401, and a program 402 a is a program for causing the CPU 401 to execute this procedure. When the program is executed, the code bc indicating the preparation amount wf, the type of bread, and the like, which are values input by the operator in advance, are stored in the parameter area 403a of the RAM 403. Then, 0 is set in the other parameter area 403a.

  First, in step S <b> 501, the total water supply amount ww is calculated and obtained, and the value is stored in the RAM 402. In the following description, data is stored in the RAM 403, and the storage destination is not specified. The total water supply amount ww is obtained from the bread type bc and the feed amount wf given by the operator with reference to the blending table in the ROM 402. Alternatively, the operator may input the value of the total water supply ww itself.

  Next, in step S502, the ambient temperature ta, the powder temperature tf, and the auxiliary material temperature ts are read from the corresponding temperature sensors and stored. In step S503, the target temperature tw of the water supply is calculated from the ambient temperature ta, the powder temperature tf, the auxiliary material temperature ts, and the total water supply amount. The target temperature tw of water is calculated according to Equation 1 or Equation 1 '. Here, the kneading time Time, the finishing temperature T, the charged amount (weight of the main material) wf, the weight ws of the auxiliary material, and the weight ww of the water are obtained from the blending table by the specified charged amount wf and bread type code bc. . In addition, a value stored in the ROM 403 in advance is used as a constant such as the specific heat of water used for the calculation.

  In step S504, the temperature sensor values of the hot water tank 201, the cold water tank 202, and the ice breaker 204 (respectively temperatures twh, twc, and ti) are read and stored. In step S505, the target temperature t is compared with the cold water temperature twc. If the target temperature t is smaller, in step S506, the blended cold water weight wc and ice weight wi are calculated according to the above-described equations 4 and 5, respectively, and stored. At that time, the measured and stored cold water temperature twc, ice temperature ti, and total water supply amount ww are used as parameters. Values prepared in advance in the ROM 403 are used for constants such as melting heat Hm and specific heat of ice.

  On the other hand, if the target temperature t is equal to or higher than the cold water temperature twc, the target temperature t is compared with the hot water temperature twh in step S507. As a result of the comparison, if the target temperature t is lower than the warm water temperature twh, the blended cold water weight wc and warm water weight wh are calculated and stored in step S508. Equations 2 and 3 are used for the calculation. At that time, the measured and stored cold water temperature twc, hot water temperature twh, and total water supply amount ww are used as parameters.

  On the other hand, if it is determined in step S507 that the hot water temperature twh is equal to or higher than the target temperature t, the heater 201b of the hot water tank 201 is driven to start heating in step S510. In step S511, the temperature detected by the temperature sensor 201a is read and compared with the target temperature t. Heating is continued until the target temperature is reached, and when the target temperature t is reached, the heating of the heater 201b is stopped and heating is stopped in step S512. In step S513, the value of the total water supply ww is substituted for the hot water weight wh and stored.

  Finally, in step S509, each component is supplied to the mixing tank 203 according to the blending weights of hot water, cold water, and shaved ice determined in the above-described procedure, and water obtained by mixing them is discharged to the outside.

<Mixing and water treatment>
6 and 7 are diagrams showing details of step S509. 6 and 7, cold water, ice, and hot water are sequentially supplied to the mixing tank 203 by a constant weight T, and this is repeated until the target weight ww is reached. In step S601, a variable WM indicating the supply weight of water and ice in the mixing tank 203 is initialized to zero. A variable WM (referred to as supply weight) indicates the weight of the contents of the mixing tank 203 at the time when cold water, ice, and hot water are supplied at a constant weight T, or when a certain component is supplied. In step S602, the supplied weight WM is compared with the total water supply amount ww. If the supply weight WM is equal to or greater than the total water supply amount ww, the target water amount has been obtained in the mixing tank 203. Therefore, the flow branches to step S630 to drive the motor 308, and the piston 301 is raised to raise the mixing tank 203. Are discharged (ie, water is supplied to a mixer or the like).

  If it is determined in step S602 that the supply weight WM has not reached the total water supply amount ww, it is determined in step S603 whether the cold water weight wc is 0 or less. If it is 0 or less, the supply of cold water is unnecessary, and the process branches to step S612. If the cold water weight wc is larger than 0, the pump 210 is started to be driven and water is supplied from the cold water tank 202 to the mixing tank 203 in step S604. In step S605, the latest weight wm, which is the value of the weight sensor 305, is read and stored. In step S606, the value obtained by subtracting the supply weight WM from the current weight wm, that is, the weight supplied by driving the pump in step S604 is compared with the cold water weight wc. The cold water weight wc indicates the remaining supply amount to be supplied. If the difference wm-WM between the newest weight and the supplied weight is equal to or greater than the cold water weight wc, the cold water is supplied to the mixing tank 203 as much as necessary, so that the cold water weight wc is set to 0 in step S609 and the process branches to step S610. To stop the supply of water from the cold water tank 202. In step S611, the supply weight WM is updated with the latest weight wm.

  On the other hand, if the difference wm-WM between the latest weight and the supplied weight has not reached the cold water weight wc, the difference wm-WM between the latest weight and the supplied weight is compared with a predetermined constant weight T in step S607. . When the difference wm-WM between the latest weight and the supplied weight reaches the constant weight T, the remaining amount of cold water supplied is updated by subtracting the constant weight T from the cold water weight wc in step S608. If not, the process branches to step S605 to repeat the procedure of reading the value of the weight sensor 305.

  The supply of cold water has been completed so far, or even if it has not been completed, the supply of a constant amount T has been completed, so the supply of cold water is stopped. In step S612, it is determined whether the ice weight wi is 0 or less. If it is 0 or less, the supply of cold water is unnecessary, and the process branches to step S621. If the ice weight wc is larger than 0, in step S613, the ice breaker 204 is driven to supply ice (shaved ice or sherbet ice) from the ice breaker 204 to the mixing tank 203. In step S614, the latest weight wm, which is the value of the weight sensor 305, is read and stored. In step S615, the value obtained by subtracting the last stored supply weight WM from the current weight wm, that is, the weight supplied by driving the ice breaker 204 in step S613 is compared with the ice weight wi. The ice weight wi indicates the remaining supply amount to be supplied. If the difference wm-WM between the latest weight and the supplied weight is equal to or greater than the ice weight wi, the ice is supplied to the mixing tank 203 as much as necessary, so the ice weight wi is set to 0 in step S618 and the process branches to step S619. 204 is stopped and the supply of ice from the ice breaker 204 is stopped. In step S620, the supply weight WM is updated with the latest weight wm.

  On the other hand, if the difference wm-WM between the latest weight and the supplied weight has not reached the ice weight wi, the difference wm-WM between the latest weight and the supplied weight is compared with a predetermined constant weight T in step S616. . If the difference wm-WM between the newest weight and the supplied weight reaches the constant weight T, the remaining amount of ice is updated by subtracting the constant weight T from the ice weight wi in step S617. If not, the process branches to step S614 to repeat from the procedure of reading the value of the weight sensor 305.

  Up to this point, the supply of ice has been completed, or even if it has not been completed, the supply of a certain amount T has been completed, so the supply of ice is stopped. Next, in step S621, it is determined whether the warm water weight wh is 0 or less. If it is 0 or less, the supply of warm water is unnecessary, and the process branches to step S602. If the hot water weight wh is greater than 0, the pump 209 is started to be supplied to the mixing tank 203 from the hot water tank 201 in step S622. In step S623, the latest weight wm which is the value of the weight sensor 305 is read and stored. In step S624, a value obtained by subtracting the last stored supply weight WM from the current weight wm, that is, the weight supplied by driving the pump in step S622 is compared with the hot water weight wh. The warm water weight wh indicates the remaining supply amount to be supplied. If the difference wm-WM between the latest weight and the supplied weight is equal to or greater than the warm water weight wh, the warm water is supplied to the mixing tank 203 as much as necessary, so that the warm water weight wh is set to 0 in step S627 and the process branches to step S628. Is stopped to stop the supply of water from the hot water tank 201. In step S629, the supply weight WM is updated with the latest weight wm.

  On the other hand, if the difference wm-WM between the latest weight and the supply weight has not reached the hot water weight wh, the difference wm-WM between the latest weight and the supply weight is compared with a predetermined constant weight T in step S625. . When the difference wm-WM between the latest weight and the supplied weight reaches the constant weight T, the remaining amount of hot water supplied is updated by subtracting the constant weight T from the hot water weight wh in step S626. If not, the process branches to step S623 to repeat the procedure of reading the value of the weight sensor 305.

  When step S629 ends, the process branches to step S602, where it is determined whether or not the total sum has reached the target weight for all components, that is, cold water, hot water, and ice.

  With the above configuration and control procedure, it is possible to supply water having a temperature that reaches a certain temperature by absorbing (or releasing) a certain amount of heat. In particular, even if the calculated water temperature of the water to be supplied is a water temperature that is difficult to stably supply with an ordinary simple cooling device, for example, about 4 ° C. or less, the water equivalent to the water temperature should be stably supplied. Can do.

  Furthermore, the specific heat and weight of other materials mixed and stirred with water and the target temperature of the product obtained by mixing and stirring these materials and water are clarified in advance, and the temperature of the material at the time of mixing is measured. Thus, the water temperature required to finish the product to the target temperature can be determined. And by providing the function of measuring the temperature of water or ice, it is possible to supply target water temperature or ice water that is thermally equivalent thereto.

  Furthermore, in the water supply device of the present embodiment, shaved ice is used as ice to be mixed with water. Therefore, even if the supplied water is directly supplied to the mixer, the mixer member, particularly the stirring blade member, is damaged. There is no risk of giving. In addition, because ice is in the form of fine particles or pillars, it is easily melted by the heat generated by mixed materials such as wheat flour and the kneading, and the dough takes about the same kneading time as kneading only with water. Can finish.

  Also, by preparing a product blending table in the water supply device, even if the operator does not know the product recipe, the water supply device of the present invention can be used to provide water at the optimum temperature for the product. Can be supplied. Therefore, it is possible to manufacture a product with stable quality without depending on the knowledge and skill of the operator.

  In particular, in the present embodiment, bread dough is taken as an example of the product, and as other substances mixed with water and kneaded, flour as a bread material and other auxiliary materials are assumed. For this reason, in the production of bread, by preparing a blending table in the water supply device, even if the operator does not know the recipe of the bread to be manufactured, the water at the optimum temperature for the production of bread dough by the water supply device of the present invention. Can be supplied. For this reason, it is possible to produce a dough with stable quality and, in turn, produce a bread with stable quality, without depending on the knowledge and skill of the operator.

[Modification]
(1) In the present embodiment, bread dough is taken as an example of the product, and as other substances mixed with water and kneaded, wheat flour and other secondary materials are assumed. However, it can be used for other products as long as the purpose is to supply water for finishing the product to a constant temperature. Of course, in order to do so, it is necessary to use the specific heat and temperature rise rate of the substance as the product material instead of the specific heat and temperature rise rate of the bread material. The format of the calculation formula is the same as in the embodiment.
(2) Further, in the present embodiment, the supplied object is water, but the water supply apparatus of the present embodiment can be applied to general liquids as well as water. In this case, the calculation is performed using the specific heat or melting heat of the liquid instead of the specific heat of water or the melting heat of ice. The format of the calculation formula is the same as in the embodiment.

(3) In the water supply device of this embodiment, the water supply pipes 209a and 210a and the water intake pipe 213a are connected to the holes provided in the piston 301, and water is supplied or taken from the bottom of the mixing tank. 209a and 210a may be attached to the upper surface of the mixing tank 203 so that water is supplied from above. Further, the water intake pipe 213 a can be attached to the side wall of the mixing tank 301. By doing in this way, the structure of piston 301 can be simplified. In addition, this can prevent shaved ice from entering the hole of the piston 301.
(4) The power source of the drive unit 307 is not limited to a motor, and hydraulic power or air pressure can be used as a power source.
(5) Instead of the bellows frame 309 or in addition to the bellows frame 309, a piston ring that contacts the inner wall of the mixing tank 203 may be provided on the piston 301 to prevent water leakage.

(6) The temperature of ice used in the present water supply device is at most about several degrees below freezing point, and in many cases, it is expected that the amount of ice contained in water is not so large. Is not considered. However, considering that the specific heat of ice is almost half of water, the ice at the temperature ti is the same amount as when the temperature of water of the same weight (ti / 2-Hm) rises to 0 ° C due to melting. Since it absorbs heat, it can be said to be equivalent to water at a temperature (ti / 2-Hm). Therefore, Expression 4 and Expression 5 become Expression 4 ′ and Expression 5 ′ below, respectively.
wc = (t-ti / 2 + Hm) / (twc-ti / 2 + Hm) * ww (Equation 4 '),
wi = ww-wc = (t-twc) / (ti / 2-twc-Hm) * ww (Formula 5 ')
(7) In the present embodiment, the kneading time Time, the finishing temperature T, the water weight ww, and the auxiliary material weight ws are specified using the code bd indicating the type of bread and the preparation amount wf as parameters. However, in order to manufacture bread of a type for which no blending table is prepared, the operator can directly input the kneading time Time, the finishing temperature T, the water weight ww, the powder weight wf, and the auxiliary material weight ws. good. In this case, if there is no code bd corresponding to the blending table, these values may be input, or all of them may be input in any case without originally having the blending table.

  (8) The present invention may be applied to a single water supply as in the embodiment, but can also be applied to an apparatus in which a water supply and a mixer are integrated.

  (9) In this embodiment, the recipe table is prepared in the ROM in advance, and the bread type code bc and the preparation amount wf are specified by the operator. However, the water supply device is connected to the computer network. These parameters may be input from a remote terminal or the like. Similarly, the blending table can also be input remotely. Furthermore, it is also possible to remotely input a value uniquely determined from parameters specified by an operator other than these.

  (10) Although the water supply apparatus of the embodiment is controlled by executing the program of the procedure of FIGS. 5 to 7, the program itself can also be configured to be downloaded from a remote computer. In this case, not only the water supply device but also the downloaded program itself constitutes the invention.

  (11) In the embodiment, the sub-material is described as one. However, if there are a plurality of sub-materials to be considered for temperature control, they are also used in determining the water temperature in the same manner as the main material powder. Taken into account. That is, in Expression 1, the terms “+ (ws * Cs)” and “+ (ts * ws * Cs)” on the right side appear as many as the number of sub-materials.

  (12) In the configuration of the embodiment, the temperature of water in the mixing tank is not monitored. However, by measuring the supply temperature of the water in the mixing tank 203, it can be determined whether the water at the target temperature has been produced when the target temperature t is below the freezing point. For this reason, it is desirable to measure the temperature in the mixing tank using a temperature sensor.

  (13) Although the water supply device has been described as including various temperature sensors, a mixer used in a set with the water supply device may include these sensors, and the water supply device may be configured to receive measurement values from the mixer.

  (14) In the structure of FIG. 3, the weight of the entire mixing tank 203 including the piston 301 and its driving mechanism is measured, and the presence or absence of friction between the piston 301 and the inner surface of the mixing tank 203 is not particularly problematic. Therefore, an O-ring can be used instead of the bellows frame. Further, since the friction between the piston 301 and the inner surface of the mixing tank 203 can be sufficiently measured by using the bellows frame, the amount of water in the mixing tank 203 is measured by measuring the stress applied to the shaft 306 instead of the entire mixing tank. Can be detected. In this case, the piston 301 and the mixing tank 203 are configured so that there is no gap between the piston 301 and the inner surface of the mixing tank 203 in order to prevent water from being applied to the bellows frame.

  (15) Furthermore, in this embodiment, water and ice are measured in the mixing tank and drained in a mixed sherbet state. However, in order to supply the shaved ice more reliably, the following configuration may be employed. That is, the manufactured shaved ice is mixed with running water drained from the mixing tank, and the mixed sherbet-like ice water is supplied to the outside, for example, the bowl of the mixer. In this way, the necessary amount of ice can be supplied without leaving.

  Specifically, for example, an ice making device and an ice amount measuring device that measures the weight of ice separately from water are provided in addition to the water supply device of the embodiment. When the ice weight is calculated in the manner described in the embodiment, the calculated weight of ice is measured by the ice amount measuring device and supplied to the shaved ice device. Then, by adjusting the timing of the drainage from the mixing tank 203, the shaved ice device is operated immediately before or during the drainage, and the shaved ice discharged from the shaved ice device is caused to flow by running water, so that ice can be supplied without remaining. In the mixing tank, water is stored in the capacity described in the embodiment.

  Furthermore, an ice making machine that produces ice cubes is used as the ice making machine. This mechanism may be the same as an automatic ice maker used in a commercial refrigerator. However, in order to control the number of ice cubes supplied to the shaved ice device, for example, in an ice container for storing ice cubes discharged from an ice tray, for example, a funnel-shaped discharge port that forms a passage with a width corresponding to one row of ice cubes at the end. In addition, a structure such as a plate for pushing ice cubes toward the outlet is provided. The operation of the board is controlled by a processor. In this structure, by moving the plate toward the discharge port from the ice making device (ice container), the ice cubes arranged in a line through the funnel-shaped passage are supplied to the shaved ice device. In the middle of the ice supply path, for example, a counter is provided for detecting ice cubes with an optical sensor or the like and counting the number of passages. The weight of ice cubes is almost constant if the amount of the original water is constant, so the amount of ice supplied to the shaved ice device is obtained by (number of ice cubes) × (unit weight of ice cubes). That is, this counter functions as an ice amount measuring device. Thus, when (the number of ice cubes) × (unit weight of ice cubes) ≧ the calculated ice amount, the ice cube supply is stopped at that time. That is, the movement toward the discharge port of the plate provided in the ice container is stopped. Since the supply of ice cubes stops when the operation of the plate is stopped, the sensor is preferably provided at the entrance of the discharge port, that is, in the vicinity of the ice container. If this is not done, the ice cubes arranged after the ice cubes to be counted are also supplied to the ice container. Thereafter, the shaved ice device is driven in synchronization with the discharge of water from the mixing tank 203, and the shaved ice is dropped into running water.

  With this configuration, the calculated amount of ice can be reliably supplied. In this configuration, when ice cubes are used, an error in the amount of ice of about one ice cube is generated at most, but the error is hardly a problem if the charged amount is about 10 kilograms or more.

  In addition, when the ice cube supplied to the shaving device exceeds the capacity of the shaving device, the ice cube is divided into several degrees and supplied to the shaving device.

  Moreover, it is good also as a structure which is not equipped with an ice maker and is equipped with only the above-mentioned ice container in a water feeder. In this case, the supply of ice cubes to the ice container is performed manually.

  Moreover, it is also possible to simplify the structure by omitting the mechanism for measuring the amount of ice from the water supply device of this modification. In this case, the ice maker needs to be supplied with the ice calculated with the capacity of the embodiment according to the manual. However, even in this configuration, the advantage of the present modified example that water can be supplied without leaving a necessary amount of ice obtained by putting ice into running water is not lost.

  In addition, the technology using ice cubes and the technology for measuring the amount of ice described in this modification can be replaced by other technologies. For example, after producing shaved ice, a required amount may be measured and that amount of shaved ice may be poured into running water.

  In the case of this modification, the production and supply of shaved ice must be completed while draining water from the mixing tank 203. For this purpose, the control unit starts draining from the mixing tank (driving the piston 301) and starting driving the shaved ice device 204. However, if the amount of ice is larger than the amount of water due to restrictions on the performance of the shaved ice device, the supply of shaved ice may not be completed when drainage from the mixing tank is completed. Then, the required amount of ice cannot be added to the feed water. Therefore, the control unit measures in advance the ability of the shaved ice device 204 (the ability to produce shaved ice per unit time) and stores it in a ROM or the like. Then, based on the amount of shaved ice supplied (the ice weight calculated in the procedure of the embodiment), the time for driving the shaved ice device is calculated. The piston 301 is driven while controlling the driving speed of the piston 301 so that the supply of water in the mixing tank 203 is completed within that time.

  By doing in this way, shaved ice can be thrown into the water discharged | emitted reliably during discharge | emission (supply) of water, and it can mix | blend with preparation water without a leak.
