Description

  The present invention relates to a washing dryer that contributes to energy saving and a program therefor.

  Since the washing and drying machine uses water and electricity to wash and dry, if the optimum operation is not performed, water and electricity are wasted. In particular, a decrease in the efficiency of washing and drying due to excessive loading of the dried laundry is a matter of concern, and the washing and drying effect is also adversely affected. Even though it was washed and dried, there was too much laundry dried material, so it was not enough to remove dirt, or it was not enough to dry, and it was unavoidable to wash and dry again. Washing and drying are preferable from the viewpoint of energy use efficiency.

Recently, the issue of carbon dioxide emission regulation for achieving the Kyoto Protocol target has been highlighted, and energy saving has become a major issue, and grasping the weight of laundry dry matter to prevent overloading and improving energy efficiency Is very preferred. Various devices have already been devised to detect the excessive loading of laundry and dry matter into the laundry dryer. (See Patent Document 1). In Patent Document 1, because the error is too large to measure by weight, the amount of the laundry dried product is estimated by the bulk of the laundry dried product using a sensor, and the optimum operation is performed.

  However, in Patent Document 1, since the error is too large to measure by weight, the amount of the laundry dried product is estimated by the bulk of the laundry dried product using a sensor, and the optimum operation is performed. Such a method has a drawback that it is not precise in terms of accurately grasping the weight.

  Also, when warning about overloading, no instructions were given on what should be removed.

  Therefore, in order to solve the above-described problems, the laundry dryer of the present invention has a wireless IC tag attached to a laundry dried product, reads data from the wireless IC tag by a reading means provided, and the weight of the laundry dried product. The information is stored in the storage means provided, the total weight of the laundry dried product existing in the laundry dryer is calculated from the information, and the calculated total weight of the laundry dried product is the optimum weight. In the case of exceeding the range, the difference from the optimum weight is obtained, one or more laundry dried products corresponding to the difference are detected, and the notification means instructs to remove the one or more laundry dried items.

  As a result, when the laundry dried product is excessively added, the laundry dried product to be removed is accurately and reliably instructed. By washing and drying, the energy use efficiency can be improved, and the original function of the washing and drying machine to maintain the washing quality can be secured.

  In the washing and drying machine, the wireless IC tag is affixed to the laundry dried product, the data is read from the wireless IC tag by the reading means provided, and the information including the weight of the laundry dried product is obtained. The information is stored in the storage means provided, the total weight of the laundry dried product existing in the laundry dryer is calculated from the information, and when the calculated total weight of the laundry dried product exceeds the optimum weight range, the optimum A difference from the weight is obtained, one or more laundry dried products corresponding to the difference are detected, and an instruction is given to remove the one or more laundry dried items by the notification means.

  As a result, when the laundry dried product is excessively added, the laundry dried product to be removed is accurately and reliably instructed. By washing and drying, the energy use efficiency is improved, and the original function of the washing and drying machine for maintaining the washing and drying quality (degradation of dirt, degree of drying) can be secured.

  According to a second aspect of the present invention, in the washing / drying machine of the first aspect of the invention, a wireless IC tag is affixed to the laundry dried product, the code data is read from the wireless IC tag by the reading means provided, and the network is based on the code data Obtaining information including the weight of the laundry dried product from the information server above, storing the information in the storage means provided, calculating the total weight of the laundry dried product present in the laundry dryer from the information, When the calculated total weight of the laundry dried product exceeds the range of the optimum weight, a difference from the optimum weight is obtained, one or more laundry dried products corresponding to the difference is detected, and the one or more laundry dried products are detected by a notification unit. An instruction was given to remove the dried laundry.

  As a result, even if the wireless IC tag does not include information including the weight of the laundry dried product, the information is acquired from the information server, and therefore the same effect as that of the first invention can be obtained.

  In the third aspect of the invention, particularly in the laundry dryer of the first or second aspect, when the calculated total weight of the laundry dried product is within the optimum weight range, the laundry drying is started and stored at the end of the laundry drying. The information memorized by means was deleted.

  Thus, the laundry dryer can reliably erase the information including the weight of the laundry dried product at the end of the laundry drying, and prepare for the next laundry drying.

  According to a fourth aspect of the present invention, particularly in the washer / dryer of the first or second aspect, when the total weight stored in the storage means exceeds the optimum weight range, or when the total weight does not reach the optimum weight, the notification means Not to start or to start washing and drying.

  As a result, washing and drying with low energy efficiency is not performed or attention is paid, so that it can be expected to contribute to energy saving.

  In the fifth invention, particularly in the washing and drying machine of the first or second invention, when the total weight stored in the storage means reaches the optimum weight range, the notification means notifies or the start of washing and drying is permitted. Alternatively, washing and drying are started.

  As a result, only washing and drying with the highest energy efficiency is performed, or the user is made aware of such a state, and therefore, it can be expected to contribute to energy saving.

  A sixth invention is a program for causing a computer to execute at least one function, particularly in the washing and drying machine according to any one of the first to fifth inventions, and includes a CPU, a RAM, a ROM, a storage device, and an I / O. A part or all of the present invention can be easily realized as a program by cooperating hardware resources such as an electrical information device, a computer, and the like. Also, by distributing the program on a recording medium or using a communication line, program distribution can be realized very easily compared to other means.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a diagram showing an example of the system configuration of a washing / drying machine and its program according to the present invention.

  First, the washing / drying machine 10 will be described. The washing / drying machine 10 is a device for washing and drying the laundry dried product 1, and includes a reading unit 3 for reading information of the wireless IC tag 2 attached to the laundry dried product 1, a control unit 4 a, a washing / drying promoting unit 5, and an extra small size. Wireless communication means 6a is provided.

  The washing / drying machine 10 uses the washing / drying promotion means 5 to rotate the laundry dry matter 1 to be washed / dried or to accelerate the drying by rotation and hot air. The washing / drying promotion means 5 is rotated by the control means 4a. Rotation time, hot air temperature, etc. are controlled.

  Washing and drying involves a physical operation of rotation, and water, hot water, and hot air are used, so it may be washed and dried if it is a physically strong material such as hemp or cotton, but nylon or processed products Because there is something physically weak like By knowing in advance the laundry drying conditions set for each of these laundry dried products 1, if you control the laundry drying (rotation speed, rotation time, hot air temperature) according to the material, you can damage important clothing. However, if the total weight of the laundry dried product is in an appropriate range, it can be expected to be washed and dried very efficiently.

  Therefore, information written in the wireless IC tag 2 attached to the laundry dried product 1, that is, whether the object may be washed and dried by the washing dryer, or if the laundry can be dried, the laundry drying condition (rotation) The speed, rotation time, and hot air temperature) are obtained as appropriate, and the weight of the laundry dried product 1 is acquired.

  The information written on the wireless IC tag 2 attached to the laundry dried product 1 is simply code information, which is numerical information expressed by a numerical string of about 64 to 128 bits. You may not be able to get specific information about. In such a case, the product information server 50 on the Internet is accessed on the basis of the code information, and whether the object may be washed and dried by a washing / drying machine in the first place or if the washing / drying is possible, washing / drying Information on how appropriate the conditions (rotation speed, rotation time, hot air temperature) are, and what is the weight of the laundry dried product 1 is acquired.

  Based on such information, the control means 4a provided in the washing / drying machine 10 can control the washing / drying promotion means 5 to perform more appropriate washing / drying, so the above information is acquired. That is very beneficial. For objects with different conditions, it can also be expected to prevent destruction of the objects in accordance with the most severe conditions.

  Information acquisition from the product information server 50 as described here is preferably performed by the relay device 20 that has received a request from the washing / drying machine 10. That is, the relay device 20 includes the extra-small radio communication unit 6b, and communicates with the extra-small radio communication unit 6a included in the washing / drying machine 10 via the extra-small radio communication unit 6b. In other words, in the washing / drying machine 10, the code information of the wireless IC tag 2 attached to the laundry / dried product 1 is read by the reading means 3, and the special information of the relay device 20 is transmitted from the control means 4a via the special wireless communication means 6a. The data is transmitted to the small wireless communication means 6b, and the processing is started by the control means 4b provided in the relay device 20.

  The code information of the wireless IC tag 2 received by the control means 4b is transmitted via the LAN communication means 7b provided in the relay device 20, the LAN communication means 7c provided in the router 30, and the WAN communication means 8. It is transmitted to the name resolution server 40 existing on the Internet. The name resolution server 40 replies to which server (product information server 50) the detailed information corresponding to the code information of the wireless IC tag 2 exists, and the reverse route, that is, the WAN communication means 8. The information is transmitted to the control means 4b through the route of the LAN communication means 7c and the LAN communication means 7b.

  The control unit 4b accesses the product information server 50 obtained from the name resolution server 40, and acquires detailed information including the weight of the laundry dried product 1.

  However, the server installation is not limited to the above, and is an information server in which the name resolution server 40 and the product information server 50 are integrated, and provides detailed information corresponding directly from the code information of the wireless IC tag 2 It doesn't matter.

  Information including the weight of the laundry dry matter 1 acquired by the relay device 20 in this way is sent to the extra-small radio communication means 6b, the extra-small radio communication means 6a, and the control means 4a, and is stored in the control means 4a. (Not shown). Not only the weight, but also information on the type and identification of the laundry dried product is stored at the same time. The control means 4a calculates the total weight of the laundry dry matter stored in the storage means, and compares it with the optimum weight prepared separately.

  The optimum weight is a value having a certain range such as 4.5 kg to 5.5 kg. When the total weight of the laundry dry matter stored in the storage means falls within this range, a notification such as “Please wash and dry because the optimum weight has been reached” may be issued from the notification means 9. However, the lamp display may notify the user of washing and drying.

  Or, if the total weight of the laundry dry matter does not reach the optimum weight, it is not possible to wash and dry yet, or “It is uneconomical to wash and dry. do. Or, if you try to wash and dry forcibly in that state, you can start washing and drying after notifying you that "Washing and drying efficiency is bad. Are you really washing and drying?" It is even possible to prohibit washing and drying.

  Alternatively, when the total weight of the laundry dried product exceeds the optimum weight, the notification unit 9 notifies the user that “it is too much” and the control unit 4a controls the laundry drying promotion unit 5 and does not start the laundry drying. Such an operation may be performed.

  In this case, the control means 4a further obtains the difference between the current total weight and the optimum weight, and searches the information stored in the storage means for the laundry dry matter corresponding to the difference. Please remove the @@ sheet ", and when the user sets the total weight of the laundry dry matter within the optimum weight range, the user will be notified that the weight has reached the optimum weight. It may be performed, or it may be informed like a lamp display. In addition, after notifying that “the weight has reached the optimum weight, laundry drying is started”, the control unit 4a may control the laundry drying promotion unit 5 to automatically start the laundry drying.

  In order to obtain the optimum weight here, the optimum weight is searched by applying the following formula. That is, it suffices to search for the laundry dry matter to be taken out so that the optimum weight (upper limit)> (total weight of laundry dry matter-washed dry matter to be taken out)> optimum weight (lower limit) is satisfied. If the dried product cannot be used, the control unit 4a may perform a calculation process that combines a plurality of laundry dried products and falls within the above range.

  The information including the weight of the laundry dry matter stored in the storage means is deleted at the end of the laundry drying, for example, so that the information is reset at the end of the laundry drying to prepare for the next laundry drying. It becomes possible.

  Note that the means described in this embodiment causes hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electric / information device including an I / O, a computer, a server, and the like to cooperate. You may implement with the form of a program. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media, or distributing them using a communication line such as the Internet.

  As described above, the laundry dryer and the program thereof according to the present invention includes a wireless IC tag attached to a laundry dried product, reads data from the wireless IC tag by the reading means provided, and includes the weight of the laundry dried product. The information is acquired, the information is stored in the storage means provided, the total weight of the laundry dried product existing in the laundry dryer is calculated from the information, and the calculated total weight of the laundry dried product is within the optimum weight range. The difference between the weight and the optimum weight is obtained, one or more laundry dried products corresponding to the difference are detected, and the notification means instructs to remove the one or more laundry dried items. When the dry matter is overfilled, the laundry dry matter to be removed is accurately and surely indicated. By 燥, energy efficiency is improved, and also it is possible to secure the washing and drying machine original function of keeping the washing and drying quality.
