Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in which, since a conventional device performs cooling in an efficient manner but without setting a target time limit, it cannot perform cooling in a required time, or it performs too much cooling which requires heat retention or reheating or performs unnecessary forcible cooling, or it produces variation in finishing temperature because the time is set empirically. <P>SOLUTION: This cooling device comprises a forcible cooling means 102, a temperature detecting means 103, a counting means 104, a cooling target time period setting means 106 for setting a target time period or a target time for cooling down to a predetermined target temperature, an object temperature predicting means 107 for predicting an attaining temperature in the target time period for an object from a temperature change in a predetermined time, and a control means 108. The control means 108 uses the forcible cooling means 102 to start cooling at the time when determining that the temperature predicted by the object temperature predicting means 107 cannot attain the target temperature in the target time period. Thus, the cooling device performs cooling down to the target temperature in the target time period while saving energy. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a device for cooling a heated object such as cooked food or hot water to an appropriate temperature, and a program thereof.

  Traditionally, for example, side dishes for lunch boxes, sushi rice in which the rice is chilled with a round fan after cooking and vinegar is mixed, cold tea, potato salad, etc. In order to efficiently perform the above, there has been a heating device that takes heat after heating (see, for example, Patent Document 1).

  FIG. 6 is a side cross-sectional view of the heating device of Patent Document 1. As shown in FIG. In FIG. 5, 10 is a heating chamber, 17 is an open / close door, 18 is a mounting plate (bottom of the heating chamber), 27 is a water supply port (mist outlet), 29 is a heating means for evaporation (heating means), and 31 is a blower. Outlet, 32 is a suction port (suction part), 33 is a rotary blade (circulation means), 34 is a heat radiation means (heating means), 35 is a rotary blade drive motor, 36 is a mist outlet, 37 is a temperature detection means, 38 Is a non-contact temperature detecting means (second temperature detecting means), 39 is a control means, 40 is an oven dish (mounting dish), and 43 is a half-open state fixing means.

  In FIG. 6, the control means 39 includes a temperature detecting means 37 that detects the ambient temperature in the rotary blade (circulation means) 33 and the heating chamber 10 even when the open / close door 17 of the heating chamber 10 is open, and the surface of the object to be heated. The non-contact temperature detecting means 38, which is the second temperature detecting means for detecting the temperature, can be operated so that room temperature air is taken in from the open / close door 17 side, and the heated object or other heat is taken and blown to the object. In addition, the current temperature in the heating chamber 10 and the current temperature of the non-heated object are notified, and the temperature is efficiently cooled, and the progress of the heat removal and the current temperature can be confirmed. Further, as means for promoting the progress of heat removal, water can be applied to the bottom of the object to be heated, or mist can be blown out.

  In addition, when a low heat retention temperature is set after boiling, there is an electric air pot that is forcibly cooled by an air supply device and cooled in a short time (for example, see Patent Document 2).

  FIG. 7 is an electric air-pot control flow chart of Patent Document 2. In FIG. 7, the air supply control means once the hot water boiling is completed, the switching switch that can be switched by appropriately selecting the heat retention temperature provided in several stages is switched to the low temperature side (in FIG. When the reboil is not selected, the air supply device (shown as a pump in FIG. 7 because the air supply device is also used as a hot water supply pump) until the selected heat retention temperature is reached. It is forcibly cooled by turning on and supplying air into the container, and can be cooled to the target heat retention temperature in a short time.

  In addition, in order to safely take out hot clothing, there has been a clothing dryer that estimates the amount of clothing from the degree of temperature rise during drying and cools it for a time corresponding to the amount of clothing (see, for example, Patent Document 3).

  FIG. 8 is an operation flowchart of the controller of the clothes dryer of Patent Document 3. In FIG. 8, first, the drying control means heats the inside of the rotary drum of the clothes dryer in STEP 1 to STEP 3, and the cooling control means starts a timer in STEP 4, and the detected temperature TC of the clothes temperature thermistor is set in STEP 5. Until the detected temperature TE of the exhaust temperature thermistor 15 reaches 59 ° C. or higher in STEP 20, warm air with a certain amount of heat is supplied into the rotating drum.

  When the detected temperature TC of the clothing temperature thermistor becomes 101 ° C. or higher in STEP 5, the cooling control means holds the measurement time of the timer in STEP 6 from the start of drying to the memory variable ti, and in STEP 20, the exhaust temperature thermistor When the detected temperature becomes 59 ° C. or higher, the cooling control means holds the measurement time of the timer up to that time in the storage variable th in STEP 21.

  In subsequent STEP7 to STEP9, the detected temperature TC of the clothing temperature thermistor does not exceed 101 ° C. (rotating drum overheated state), and the detected temperature TE of the exhaust temperature thermistor does not exceed 66 ° C. (exhaust pipe overheated state). The temperature of the exhaust temperature thermistor detected at the time point tm (hereinafter referred to as semi-drying) is reached after the clothes are dried until it is determined that the degree of drying reaches 95% or more while adjusting the heating. Is stored in the storage variable TEH (STEP 10). Then, the drying control means supplies the remaining time (dry remaining time) td of the drying operation necessary to completely dry the clothing M in the rotating drum, and supplies the cold air to the rotating drum after the drying operation is completed. First, the execution time (cooling time) tC of the cooling operation is determined (STEP 11 to STEP 12).

  When the drying operation is continued with a certain amount of heat from the start of the drying operation, the time until the temperature detected by the clothing temperature thermistor reaches 101 ° C. or more is when the amount of clothing M is smaller when the amount of clothing M is larger. Longer than. Therefore, the cooling control means uses ti held in STEP 6 (time from the start of the drying operation until the detected temperature TC of the clothing temperature thermistor reaches 101 ° C.) or th held in STEP 21 (detected temperature of the exhaust temperature thermistor from the start of the drying operation). The remaining time of the drying operation (drying) required to completely dry the clothing M in the rotating drum by estimating the amount of the clothing M accommodated in the rotating drum from the time until TE reaches 59 ° C. Remaining time) td and after the drying operation, cool air is supplied to the rotating drum and the garment M is touched. By determining the cooling operation execution time (cooling time) tC, the cooling time can be appropriately set according to the amount of clothing. The length is automatically set.

  Furthermore, there has been a refrigerator-freezer in which the time and time for rapid cooling operation can be set (see, for example, Patent Document 4).

In the refrigerator-freezer disclosed in Patent Document 4, since the end of the rapid cooling time or the rapid cooling time is notified by a display device that emits a sound such as an alarm, the refrigerator can be cooled without being overcooled over a set time or time.

  However, the work of cooling is often accompanied by a time limit of cooling by this time. For example, if you want to cool a cup of tea in the water bottle of an infant or school child who wants to drink hot tea but can't drink hot tea in the winter, finish it with just the right cooling before the school attendance at kindergarten or school. Must be pinched in a water bottle. Lunch boxes must be cooled by the time you leave the house. On the other hand, there are cases where the time limit may be in time for the next use.

In the heating device described in the above-mentioned Patent Document 1, the cooling is efficiently performed by various forced cooling, and the progress of the heat removal and the current temperature can be confirmed, but the user cools regardless of the cool time. It is necessary to wait while confirming the progress of the take-up at the current temperature from time to time, and if it is not in time for the time when the heat is needed or if it is not taken out when the desired heat is taken, it is too cold Therefore, there was a problem that heat insulation and reheating were necessary.

  Moreover, in the electric air pot described in the above-mentioned Patent Document 2, when a low heat retention temperature is set after boiling, it can be cooled in a short time by forcibly cooling it with an air supply device. Regardless of the condition, forced cooling is performed by the air supply device. For example, breastfeeding is used to replenish water after use, and after 3 to 4 hours it is necessary 3-4 hours later. It had the problem of not becoming.

  In addition, since the clothes dryer described in Patent Document 3 automatically cools for an appropriate time according to the amount of clothes, it is possible to safely remove hot clothes regardless of the amount of clothes. Although it is possible to estimate the amount of clothing from the degree of temperature rise during drying, it is good that there is a heating process in the equipment as in the case of clothes dryers and heaters. In the case where only the process is performed with the equipment, there is a problem that an appropriate cooling time cannot be automatically set.

  Furthermore, although the refrigerator-freezer described in the said patent document 4 can cool without overcooling more than the set time and time, since the user does not know an appropriate time to cool a to-be-cooled object to target temperature, it sets The time and time to perform had the subject that it had to be set appropriately by experience value.

(Embodiment 1)

FIG. 2 is a flowchart showing the operation flow of the cooling device, and FIG. 3 is an explanatory diagram of temperature prediction up to the target time of the cooling device. Furthermore, FIG. 4 is an example of a predicted arrival temperature notification for a target time point midway until the cooling target time of the cooling device, and FIG. 5 is a notification when the predicted arrival temperature of the cooling device cannot reach the target temperature at the target time. There are examples.

  In FIG. 1, 101 is a cooling device of the present invention, 102 is a forced cooling means, 103 is a temperature detecting means, 104 is a time measuring means, 105 is a cooling target temperature setting means, 106 is a cooling target time setting means, and 107 is an object. The temperature predicting means, 108 is a control means, 109 is a cooling capacity variable means, 110 is a target temperature selection means, 111 is a notification means, 112 is a midway target time storage means, and 113 is a midway target temperature storage means.

  About the cooling device comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the user puts the object to be cooled in the cooler 101 and sets the target temperature to be cooled by the cooling target temperature setting means 105. The setting in the cooling target temperature setting means 105 is set by selecting from the options of the target temperature option means 110 (in this embodiment, 80 ° C .: use of tea, 60 ° C .: prepare options for milk or infant drinking, etc.) You can also set it by specifying the temperature. In addition, the user sets the cooling completion time (in this embodiment, after several minutes) to the cooling target temperature set by the cooling target temperature setting means 105 by the cooling target time setting means 106 (step 1).

  Next, although not shown, when the user gives a cooling start instruction, the control means 108 of the cooling apparatus 101 starts natural cooling (step 2).

  Next, the control means 108 detects the temperature of the object with the temperature detection means 103 (non-contact temperature sensor in this embodiment), and notifies the current temperature (initial temperature at the start of cooling) with the notification means 111, The object temperature predicting means 107 first performs the initial prediction until data enough to be predicted are collected (which depends on the amount of the object, the initial temperature, and the target temperature, but in this embodiment, About 3 minutes), the temperature detecting means 103 monitors the temperature decreasing gradient after the start of natural cooling (steps 3 to 4).

  After the data that can be predicted is prepared and the preparation for the initial prediction is completed, the object temperature prediction means 107 predicts the object temperature at the target time (step 5). Further, the object temperature predicting unit 107 stores the intermediate target time point up to the target time stored in the intermediate target time point storage unit 112 (in this embodiment, the time point where the target time is divided into five, for example, the target time is 15 minutes) If it is later, the temperature of the object at 3 minutes, 6 minutes, 9 minutes, 12 minutes, and 15 minutes) is predicted (step 6) and stored in the target temperature storage means 113 on the way. Intermediate target temperature up to the target temperature (in this embodiment, a maximum of five points every 5 ° C. near the temperature at the start of cooling and the target temperature until the target temperature time, for example, the temperature at the start of cooling is 100 ° C. and the target temperature is 60 ° C. If so, the time required for the temperature of the object to reach 85 ° C, 80 ° C, 75 ° C, 70 ° C, 65 ° C) is predicted (step 7).

When the predicted temperature of the object at the target time predicted by the object temperature prediction means 107 is lower than the target temperature, the control means 108 does not perform forced cooling by the forced cooling means 102 or stops (step 8, Step 12 and Step 14) When target temperature> predicted temperature ≧ (target temperature−5 ° C.), the prediction result has not been notified, or there is a deviation from the already notified prediction result by a predetermined value or more ( In the present embodiment, when there is a deviation of 5 ° C. or more in the predicted temperature at the target time, the notification means 111 predicts as shown in FIG. 4 (example of predicted temperature at the target time halfway up to the target time). The result is notified (steps 15 to 18), and if the target time has not elapsed (step 19).
), Return to step 3. When forced cooling by the forced cooling means 102 is stopped this time, since the temperature decreasing gradient changes greatly due to the change from forced cooling to natural cooling, it is necessary to redo the initial prediction, so that the prediction is newly determined. Let natural cooling.

  The control means 108 performs forced cooling in the forced cooling means 102 when the predicted temperature of the object at the target time predicted by the object temperature prediction means 107 is predicted temperature <(target temperature-5 ° C.). After not stopping or stopping (Step 8, Step 12, Step 14), the notification means 111 informs the user that the target temperature cannot be reached at the target time due to overcooling, for example, and the time for reaching the target temperature is notified. (Step 8, Step 12, Step 14, Step 15, Step 11).

  Further, the control means 108 is forced by the forced cooling means 102 when the predicted temperature of the object at the target time predicted by the object temperature prediction means 107 is (target temperature + 5 ° C.) ≧ predicted temperature ≧ target temperature. Start or continue operation of the cooling means 102. In the present embodiment, forced cooling is performed while adjusting the capacity by the cooling capacity variable means 109 according to the difference between the target temperature and the predicted temperature (step 8, step 12, and step 13). At the same time, the notification means 111 notifies the prediction result (steps 16 to 18). If the target time has not elapsed (step 19), the process returns to step 3. When forced cooling by the forced cooling means 102 is started this time or when the capacity is changed by the cooling capacity changing means 109, the temperature decreasing gradient changes greatly due to forced cooling, so it is necessary to redo the initial prediction. The ability is fixed until it is newly confirmed.

  Furthermore, the control means 108 starts or continues the forced cooling means 102 when the predicted temperature of the object at the target time predicted by the object temperature prediction means 107 is higher than the target temperature by 3 ° C. . In the present embodiment, forced cooling is performed at the maximum capacity by the cooling capacity variable means 109 (steps 8 and 9), and when the forced cooling at the maximum capacity is continuously less than 20 minutes, the prediction result is notified by the notification means 111. If the target time has not elapsed (step 19), the process returns to step 3. When the forced cooling in the forced cooling means 102 is newly changed to the maximum capacity by the current cooling capacity changing means 109, the temperature decreasing gradient is greatly changed by the forced cooling, so it is necessary to redo the initial prediction. Until it is newly confirmed, it is fixed to the maximum capacity. When forced cooling at the maximum capacity is continued for 20 minutes or more, the notification means 111 cannot reach the target temperature at the target time as shown in FIG. 5, and it is transferred to, for example, a container with good heat conduction. Notification of countermeasures such as changing or opening the door of the cooling device 101 is given (steps 8 to 11).

The ability of the forced cooling means 102 is controlled by the cooling capacity variable means 109 to the minimum capacity that makes the temperature reached at the target time equal to the target temperature, so that energy can be saved by the required time limit. It is possible to provide a cooling device that can cool to a target temperature by a simple cooling method.

  Furthermore, a target temperature selection means 110 is provided, and the target temperature can be selected from the target temperature selection means 110, so that the user can easily set the target temperature without knowing the optimum temperature for the object. Can be provided.

  Further, the control unit 108 includes a notification unit 111, and the control unit 108 predicts an object that the object temperature prediction unit 107 predicts for a predetermined intermediate target time up to the cooling target time stored in the intermediate target time storage unit 112. By notifying the ultimate temperature, it is possible to obtain information on the temperature guideline at a predetermined point in the early stage after the user starts cooling, so that the user can set up other work. Can be provided.

  Further, the control means 108 notifies the predicted arrival time of the object predicted by the object temperature prediction means 107 for the predetermined intermediate target temperature up to the cooling target temperature stored in the intermediate target temperature storage means 105. Thus, it is possible to provide a cooling device that can obtain information on a time guide that can reach a predetermined temperature at an early stage after the user starts cooling and allows the user to set up other work. .

  Further, the control means 108 divides the temperature at the target time predicted by the object temperature prediction means 107 notified by the notification means 111 and the prediction of the subsequent object temperature prediction means 107 by a predetermined value or more during the cooling process. By notifying the correction at the time, it is possible to provide a cooling device that allows the user to obtain correct correction information early and to correct the setup of other work.

  Furthermore, when the predicted arrival temperature of the object predicted by the object temperature prediction means 107 cannot reach the predetermined target temperature at the target time, or is too cool below a predetermined value than the target temperature, it cannot be achieved or By informing the countermeasure advice, it is possible to provide a cooling device that can perform efficient cooling by the user's countermeasure even when it cannot be achieved or prompt the user to take out at an appropriate timing.

  In this embodiment, the target cooling temperature can be set by the cooling target temperature setting means 105. However, a predetermined cooling target temperature (for example, 60 ° C. for milk) may be used. Further, in the present embodiment, the target time setting in the cooling target temperature setting means 105 is set after a few minutes, but the time may be set.

It does not matter whether it is predicted or any one of them may be predicted, and the target time on the way may be set every 1 minute regardless of the target time, or after 1 minute, 5 minutes, and the fixed time point. Further, the intermediate target temperature may be an arbitrary intermediate temperature.
