Description of the invention (f) [Technical field to which the invention belongs] The present invention relates to a dry ice generating device for cooling out-commodities and the like. [Prior art] In the past, necessary refrigerated goods from outside the store were added with the necessary amount of solid dry ice that was properly pulverized by the store staff. Due to the danger of frostbite, etc., when the hand directly touched the solid dry ice, it was necessary to handle it. Special care must be taken. The sales at the storefront are required to be quite fast, and in the case of adding dry ice to the product, gloves must be worn every time, especially for the retail store, which causes great obstacles to the storefront transaction. In order to solve such a problem, the applicant of the present invention proposed in the 2009 patent application No. 362597 "a dry ice generating device characterized in that an expansion cylinder is erected on the upper part of a working chamber provided with a door, and the expansion A nozzle for spraying liquefied carbon dioxide for dry ice generation is installed at the upper end of the cylinder, and a control device is provided to supply the generated dry ice to a container opened at the lower end of the expansion cylinder within a certain period of time. " This allows powdery dry ice to be quickly and safely spread around the products to be refrigerated at the storefront. [Problems to be Solved by the Invention] Although the supply time of the liquefied carbon dioxide in the dry ice generating device is fixed, depending on the conditions, the amount of dry ice generated is not fixed. The present invention has been made in order to solve this new problem. [Means to solve the problem] The first form of the dry ice generating device of the present invention to solve the above-mentioned problem is that an expansion cylinder is erected on the upper part of the supply chamber. National Standard (CNS) A4 Specification (210 X 297 mm) (Please read the precautions on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs----I-U1 I 11111111--- — — — — — — — — — — — — — — — — — — 508427 Printing of clothing A7 B7 by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Description of the invention (> The carbon dioxide nozzle supplies the generated dry ice to a container opened at the lower end of the expansion cylinder; it is characterized by having: a peripheral temperature detection mechanism for detecting the surrounding temperature, and a discharge time determination mechanism, which can The detected ambient temperature determines the discharge time of carbon dioxide in such a way that the amount of dry ice generation becomes a predetermined amount. When the surrounding temperature is high, because the emitted carbon dioxide is not easy to become dry ice, compared with the case where the surrounding temperature is low, it must take a longer time to produce the same amount of dry ice. Therefore, the ejection time determining mechanism is based on the detected The ambient temperature is determined by the amount of dry ice generated so that the amount of carbon dioxide is ejected. When determining the ejection time, a function or a comparison table obtained in advance through experiments and the like is used to determine the ejection time. A predetermined amount or a target dry ice generation amount input from the outside each time it is used. In addition, the second form of the dry ice generation device of the present invention is in the same dry ice generation device, and is characterized by having: An air pressure detecting mechanism for detecting the pressure of raw material carbon dioxide, and a discharge time determining mechanism can determine the discharge time of carbon dioxide in accordance with the detected gas pressure so that the amount of dry ice generated becomes a predetermined amount. When the carbon dioxide of the raw material is, for example, from a high-pressure container, (Storage tank) When the carbon dioxide pressure in the high-pressure container is low, Compared with the higher case, the amount of dry ice produced by the same time spraying is less. The supply from other supply sources (such as when directly transported from the factory through pipelines) 4 The paper size is applicable to the country of China Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out this page); 0 ------ 1 Order --------- Line ---- ------------------ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 508427 A7 B7 5. The description of the invention ($) is also the same. That is, the air pressure also forms dry ice generation One of the reasons for the amount change. Therefore, as described above, the ejection time determination mechanism will determine the ejection time of carbon dioxide according to the detected air pressure to generate a predetermined amount of dry ice. Here, in determining the ejection time, a function or a comparison table obtained in advance through experiments or the like is also used. The third aspect of the dry ice generating device of the present invention is the same dry ice generating device, and is characterized by comprising: an elapsed time calculating means for calculating an elapsed time since the end of the previous carbon dioxide emission, and an ejection time determining means According to the calculated elapsed time, the discharge time of carbon dioxide can be determined so that the amount of dry ice generated becomes a predetermined amount. Just after the carbon dioxide is sprayed to generate dry ice, the temperature of the flow path of carbon dioxide and the expansion cylinder will decrease, However, after the carbon dioxide emission is stopped, the temperature gradually rises to the surrounding temperature (room temperature) over time. Although the amount of dry ice produced is large during a period when the temperature of the flow path or the expansion cylinder is low, the amount of dry ice produced decreases as the temperature rises. Therefore, in the same manner as described above, the ejection time determining mechanism determines the ejection time of carbon dioxide in consideration of the ejection interval to generate a predetermined amount of dry ice. Similarly, when determining the ejection time, a function or a comparison table obtained in advance through experiments or the like is used. In addition, the device of the present invention is capable of generating a predetermined amount of dry ice regardless of various conditions, and also has convenience and safety. Therefore, the device of the present invention is suitable for a vending machine such as a store. Therefore, install 5 paper sizes in these dry ice generating units to comply with Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) .. · ----- --- Order --------- line · 508427 A7 B7 V. Description of the invention (f) Currency (coin and / or banknote) identification device, when the predetermined amount of currency is inputted, the ejection time determination mechanism starts The operation may be started to generate and supply dry ice. [Embodiment of Invention] The above shows the device for determining the carbon dioxide ejection time according to three parameters: ambient temperature, raw material carbon dioxide pressure, and elapsed time (ejection interval) after the last ejection. Of course, these parameters are determined. They may be appropriately combined according to the use environment and the like. For example, when the most accurate control is to be performed, as shown in FIG. 1, a peripheral temperature detection mechanism 2, an air pressure detection mechanism 3, and an elapsed time calculation mechanism 4 are installed, and the ejection time determination mechanism 1 uses these three parameters. It is also possible to determine the carbon dioxide emission time. In the example of FIG. 1, the discharge time determined by the discharge time determining mechanism 1 is transmitted to the discharge valve control device 6, and the discharge valve control device 6 opens the discharge valve 7 only at this time to generate a predetermined amount of dry ice. The discharge valve control device 6 transmits and stores the time when the discharge valve is closed to the time memory mechanism 5. The elapsed time calculation means 4 reads the ejection stop time memorized by the time memory means 5, and calculates the difference between the present time and the current time to calculate the elapsed time since the end of the previous ejection. On the other hand, when used in an environment where the ambient temperature hardly changes, it is sufficient to consider two parameters such as air pressure and discharge interval. In addition, when carbon dioxide can be constantly supplied at a certain pressure, or when the capacity of the high-pressure vessel (storage tank) is extremely large and the pressure change is very gradual, the pressure detection mechanism 3 is not provided, and the pressure is changed only by a simple manual selection switch. It may be transmitted to the ejection timing determining mechanism 1. 6 scales are applicable to China National Standard (CNS) A4 specifications (210 x 297 mm) (Please read the note on the back?

Invention Description (j) Just how long (seconds) it takes to produce the desired amount of dry ice. An example of the relationship thus obtained is shown in FIGS. 3 and 4. The graph in Fig. 3 is a case where the pressure of carbon dioxide is 26 kg / cm2, and the time interval between the previous spraying and the surrounding temperature are parameters. The carbon dioxide spraying time required to generate 150 g of dry ice is obtained. The graph in FIG. 4 shows the carbon dioxide emission time required to generate 150 g of dry ice when the ambient temperature is 30 ° C, and the time interval and air pressure from the previous ejection are parameters. Based on these data, a comparison table is created and stored in the invariable memory. This memory is installed in the control device 20, and in actual operation, the temperature sensor 19, the air pressure sensor 23 (or the manual selection switch appropriately selected by the manager or the like according to the air pressure), and the elapsed time calculation mechanism Each parameter (to be described later) is input into the comparison table, and the ejection time required to generate a desired amount of dry ice is obtained by interpolation processing or the like. In addition, instead of memorizing in a memory in the form of a look-up table as described above, based on the experimental data, a function for calculating the ejection time from each parameter may be obtained in advance and may be memorized in a memory or the like. The following processes are performed inside the device. When the main switch 21 is turned on, the control device 20 performs processing as shown in the flowchart of FIG. 2. Here, in the case where the device is coin-operated, the following operations are performed after coin input of a predetermined amount is detected by the coin identification device 24. First, it is checked whether the supply button 25 is pressed by an interrupt or the like (step S1). Moreover, in the case of coin-operated type, for the sake of sufficient security measures, the supply button 25 is abolished, and the coin is started at the same time as the predetermined amount of coins is inserted.

The supply action under the description of invention (y) is sufficient. When the supply button 25 is pressed, the ambient temperature T is first input from the temperature sensor 19 (step S2), and the pressure P in the high-pressure carbon dioxide container is input from the air pressure sensor 23 (step S3), and is calculated from the elapsed time set in the control device 20. The mechanism 4 (refer to FIG. 1) calculates an elapsed time from the point at which the previous gas ejection was completed (step S4). The operation of the elapsed time calculation means 4 may be performed by the control device 20 itself. The control device 20 compares these data with a look-up table loaded in the non-volatile memory in the control device 20 to determine the ejection time (step S5). Next, a discharge start signal is output to the discharge valve control device 6 (FIG. 1) (step S6), and it waits for the time determined by step S5 to pass (step S7). At a point in time after the determined time has elapsed, a discharge stop signal is output to the discharge valve control device 6 (step S8), and the time at that point in time is loaded into the memory in the control device 20 (the time counting mechanism 5 in FIG. 1) ( Step S9). The data of the end-of-discharge time loaded here is used to calculate the elapsed time used in step S4, and the time from the beginning of the discharge to the end of the discharge can be timed inside the control device 20 as shown in FIG. 2 Or, the data of the discharge time may be transmitted to the discharge valve control device 6, and the timing may be measured on the discharge valve control device 6. A dedicated timer 22 (FIG. 5) may be used. [Effects of the Invention] The present invention adjusts the discharge time of carbon dioxide by taking into account these parameters by detecting various fluctuation conditions or measuring the discharge time interval using a sensor or the like. Therefore, regardless of the outside air temperature or the pressure of the raw material carbon dioxide, the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) ----- -1 丨 Order --------- line It ---------------------- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 508427 A7 B7 V.
