Description

本発明は洗濯機に係り、より詳しくは洗濯物を殺菌するための殺菌水供給装置を備えた洗濯機に関するものである。   The present invention relates to a washing machine, and more particularly to a washing machine provided with a sterilizing water supply device for sterilizing laundry.

銀溶液は銀イオン（Ａｇ＋）を発生させて水に溶かしたもので、抗菌剤又は殺菌剤としても使用される。銀溶液はおよそ６５０余種の細菌を殺菌（消毒）するものと報告されている。特に、銀溶液は一般の抗生物質とは異なり、耐性を持っていないという特徴があり、毒性が全くなくて非常に安全である。銀溶液を作る方法としては、電気的分解方法、化学的分解方法、粉砕方法などがある。このうち、最も高い効果を有するものが電気分解方法であるが、この方法は銀イオンを水に分解させて溶かす方法である。 The silver solution is a solution in which silver ions (Ag + ) are generated and dissolved in water, and is also used as an antibacterial agent or a bactericidal agent. Silver solutions are reported to disinfect (disinfect) approximately 650 species of bacteria. In particular, the silver solution is different from general antibiotics in that it is not resistant and has no toxicity and is very safe. Examples of methods for producing a silver solution include an electrolysis method, a chemical decomposition method, and a pulverization method. Of these, the electrolysis method has the highest effect, and this method is a method in which silver ions are decomposed into water and dissolved.

殺菌洗濯機は、このような銀溶液の抗菌及び殺菌作用により洗濯物を殺菌するように、銀溶液を製造して供給する殺菌水供給装置を採用した洗濯機である。このような従来の殺菌洗濯機及び殺菌水供給装置を図１及び図２に基づいて説明するとつぎのようである。   The sterilizing washing machine is a washing machine that employs a sterilizing water supply device that manufactures and supplies a silver solution so that the laundry is sterilized by the antibacterial and sterilizing action of the silver solution. Such a conventional sterilizing washing machine and sterilizing water supply device will be described with reference to FIGS. 1 and 2 as follows.

図１は、従来の殺菌洗濯機を示す断面図である。同図に示すように、洗濯水を入れるため、本体ケース１０２の内部に水槽１０４が設けられ、この水槽１０４の内部に洗濯槽１０６が回転可能に取り付けられる。洗濯槽１０６の内部には、洗濯水流を形成するように正回転及び逆回転するパルセーター１０８が設けられ、水槽１０４の下部には、洗濯槽１０６及びパルセーター１０８を回転させるための駆動装置１１０が設けられる。この駆動装置１１０は、駆動モータ１１２と伝動装置１１４とから構成される。この駆動モータ１１２は電源の印加により回転し、伝動装置１１４は前記駆動モータ１１２の回転力がパルセーター１０８と洗濯槽１０６に選択的に伝達されるようにする。駆動モータ１１２と伝動装置１１４間には伝動を媒介するベルト１１６が連結される。   FIG. 1 is a cross-sectional view showing a conventional sterilization washing machine. As shown in the figure, a water tub 104 is provided inside the main body case 102 for containing washing water, and a washing tub 106 is rotatably mounted in the water tub 104. A pulsator 108 that rotates forward and backward to form a washing water flow is provided inside the washing tub 106, and a driving device 110 for rotating the washing tub 106 and the pulsator 108 is provided below the water tub 104. Is provided. The drive device 110 includes a drive motor 112 and a transmission device 114. The drive motor 112 is rotated by application of power, and the transmission device 114 selectively transmits the rotational force of the drive motor 112 to the pulsator 108 and the washing tub 106. A belt 116 that mediates transmission is connected between the drive motor 112 and the transmission device 114.

図２は、従来の殺菌水供給装置を示す断面図である。まず、殺菌洗濯機に洗濯物が投入され、電源が供給された後、洗濯コースが設定されると、水槽１０４の内部に洗濯水が給水される。給水される洗濯水は洗剤溶解装置（図示せず）を経由しながら洗剤を溶解させ、洗剤とともに水槽１０４の内部に給水される。使用者が殺菌洗濯コースを洗濯した場合は、このような給水動作と同時に、殺菌水供給装置１２０の入口バルブ２０４が開放し、貯蔵容器１２２の内部に水が給水される。殺菌水供給装置１２０の２枚の銀板２２０、２２２に＋極性と−極性の電圧がそれぞれ印加されると、銀イオンが発生して銀溶液殺菌水が製造される。この銀溶液殺菌水が洗濯槽１０６の内部に給水され洗濯物を殺菌する。   FIG. 2 is a cross-sectional view showing a conventional sterilizing water supply device. First, after the laundry is put into the sterilization washing machine and the power is supplied, the washing water is supplied into the water tank 104 when the washing course is set. The washing water supplied is dissolved in the water tank 104 together with the detergent by dissolving the detergent while passing through a detergent dissolving device (not shown). When the user washes the sterilization washing course, the inlet valve 204 of the sterilization water supply device 120 is opened simultaneously with the water supply operation, and water is supplied into the storage container 122. When positive and negative voltages are respectively applied to the two silver plates 220 and 222 of the sterilizing water supply device 120, silver ions are generated to produce silver solution sterilizing water. This silver solution sterilizing water is supplied into the washing tub 106 to sterilize the laundry.

図２に示すように、貯蔵容器１２２の入口２０２を通じて給水される水は貯蔵容器１２２の第１空間２１０に満たされながら流速及び流れが安定するように整流され、第１空間２１０の水が第１仕切り２０６を越えて第２空間２１４に流れる。そして、第１空間２１０を経て第２空間２１４に流入する水は第２仕切り２０８の高さに相当する水位で第２空間２１４に満たされ、第２空間２１４に水が満たされた後、第２仕切り２０８を越えて第３空間２２４に流れ、出口２１６を通じて水槽１０４に給水される。水槽１０４に殺菌水を含む洗濯水が満たされた後、パルセーター１０８が回転しながら洗濯物を洗濯し、この洗濯過程で殺菌水により細菌が滅菌される。   As shown in FIG. 2, the water supplied through the inlet 202 of the storage container 122 is rectified so that the flow velocity and flow are stabilized while being filled in the first space 210 of the storage container 122, and the water in the first space 210 is It flows into the second space 214 beyond the one partition 206. Then, the water flowing into the second space 214 through the first space 210 is filled in the second space 214 at a water level corresponding to the height of the second partition 208, and after the second space 214 is filled with water, The water flows over the two partitions 208 to the third space 224 and is supplied to the water tank 104 through the outlet 216. After the water tank 104 is filled with washing water containing sterilizing water, the laundry is washed while the pulsator 108 rotates, and bacteria are sterilized by the sterilizing water in this washing process.

図２において、殺菌水供給装置１２０は、２枚の銀板２２０、２２２に＋極性と−極性の電圧がそれぞれ印加されるように構成される。＋極性の銀板２２０は酸化して銀イオンを発生し、この銀イオンの一部は−極性の銀板２２２に付着され還元される。−極性の銀板２２２に付着されていない残り銀イオンは水中に残り、この銀イオンが溶けている水が正に銀溶液殺菌水である。ここで、銀イオンの発生量、つまり銀溶液の濃度は、２枚の銀板２２０、２２２を通じて流れる電流量、つまり２枚の銀板２２０、２２２に印加される電圧に比例する。   In FIG. 2, the sterilizing water supply device 120 is configured such that + polarity and −polarity voltages are applied to two silver plates 220 and 222, respectively. The + polar silver plate 220 is oxidized to generate silver ions, and some of the silver ions are attached to the -polar silver plate 222 and reduced. -The remaining silver ions not attached to the polar silver plate 222 remain in the water, and the water in which the silver ions are dissolved is exactly the silver solution sterilizing water. Here, the amount of silver ions generated, that is, the concentration of the silver solution, is proportional to the amount of current flowing through the two silver plates 220 and 222, that is, the voltage applied to the two silver plates 220 and 222.

このような従来の殺菌水供給装置１２０においては、入口配管２１２を通じて貯蔵容器１２２の入口２０２に水が給水される。洗濯物を殺菌するための殺菌水である銀溶液の濃度が低すぎると、十分な殺菌効果が期待できなく、銀溶液の濃度が高すぎると、洗濯物を汚染させるおそれがある。したがって、洗濯物が汚染しないながらも十分な殺菌効果を提供するように銀溶液の濃度を制御する必要がある。   In such a conventional sterilizing water supply device 120, water is supplied to the inlet 202 of the storage container 122 through the inlet pipe 212. If the concentration of the silver solution that is sterilizing water for sterilizing the laundry is too low, a sufficient sterilizing effect cannot be expected, and if the concentration of the silver solution is too high, the laundry may be contaminated. Therefore, it is necessary to control the concentration of the silver solution so as to provide a sufficient bactericidal effect while the laundry is not contaminated.

したがって、本発明は前記のような従来の問題点を解決するためになされたもので、その目的は、殺菌水供給装置に給水される水の温度に応じて、電極に供給される電圧の大きさを制御することで、殺菌水の濃度を前もって設定された範囲内に維持する殺菌洗濯機及びその制御方法を提供することにある。   Accordingly, the present invention has been made to solve the conventional problems as described above, and its purpose is to increase the voltage supplied to the electrode in accordance with the temperature of the water supplied to the sterilizing water supply device. It is an object of the present invention to provide a sterilization washing machine that maintains the concentration of sterilized water within a preset range by controlling the depth and a control method thereof.

このような目的を達成するため、本発明は、殺菌水供給装置から給水される殺菌水の温度を温度センサなどで検出し、検出された温度に応じて殺菌水供給装置を制御することにより、殺菌水の濃度が前もって設定された範囲内の値を有するようにする洗濯機及びその制御方法を提供する。   In order to achieve such an object, the present invention detects the temperature of sterilizing water supplied from the sterilizing water supply device with a temperature sensor or the like, and controls the sterilizing water supply device according to the detected temperature. A washing machine and a method for controlling the same are provided so that the concentration of sterilizing water has a value within a preset range.

本発明による殺菌洗濯機は、殺菌水供給装置に給水される水の温度に応じて、電極に供給される電圧の大きさを設定することにより、殺菌水の濃度が前もって設定された適正範囲内で均一に維持されるようにする。   The sterilizing washing machine according to the present invention sets the magnitude of the voltage supplied to the electrode according to the temperature of the water supplied to the sterilizing water supply device, so that the concentration of the sterilizing water is within an appropriate range set in advance. So that it is kept uniform.

以下、本発明による殺菌洗濯機及びその制御方法の好ましい実施例を図３ないし図５に基づいて詳細に説明する。図３ないし図５に示す洗濯機の構造には図１と同一の参照符号を付ける。   Hereinafter, preferred embodiments of the sterilization washing machine and the control method thereof according to the present invention will be described in detail with reference to FIGS. The structure of the washing machine shown in FIGS. 3 to 5 is given the same reference numeral as in FIG.

図３は、本発明による殺菌洗濯機を示すブロック図である。同図に示すように、駆動部３０２は殺菌水供給装置３０４の銀板に＋極性と−極性の電圧を交番に印加し、この印加電圧により銀板が酸化して銀溶液を製造する。駆動部３０２から殺菌水供給装置３０４に印加される電圧の大きさは、制御部３０６から駆動部３０２に出力される電圧制御信号３１４に応じて制御される。殺菌水供給装置３０４に供給される電流量は印加電圧の大きさに比例する。   FIG. 3 is a block diagram showing a sterilization washing machine according to the present invention. As shown in the figure, the driving unit 302 alternately applies + polarity and -polarity voltages to the silver plate of the sterilizing water supply device 304, and the silver plate is oxidized by the applied voltage to produce a silver solution. The magnitude of the voltage applied from the drive unit 302 to the sterilizing water supply device 304 is controlled according to the voltage control signal 314 output from the control unit 306 to the drive unit 302. The amount of current supplied to the sterilizing water supply device 304 is proportional to the magnitude of the applied voltage.

温度センサ３１２は、殺菌水供給装置３０４を通じて洗濯機に給水されるすすぎ水の温度を検出するためのものである。温度センサ３１２は、殺菌水供給装置３０４の出口に設けられ、殺菌水供給装置３０４から洗濯槽１０６に給水される殺菌水の温度を検出する。   The temperature sensor 312 is for detecting the temperature of the rinsing water supplied to the washing machine through the sterilizing water supply device 304. The temperature sensor 312 is provided at the outlet of the sterilizing water supply device 304 and detects the temperature of the sterilizing water supplied from the sterilizing water supply device 304 to the washing tub 106.

殺菌水供給装置３０４に供給される電流量は電流検出部３０８及び電流−電圧変換部３１０により検出される。制御部３０６は、殺菌水供給装置３０４に供給される電流量が前もって設定された範囲を外れると、殺菌水供給装置３０４に印加される電圧の大きさを制御して、殺菌効果を発揮し得る適正範囲の濃度が維持されるようにする。すなわち、殺菌水供給装置３０４に過量の電流が供給されると、銀溶液の濃度があまり高くなり、銀溶液により洗濯物が汚染し得るため、これを防ぐために電流量を制限するものである。   The amount of current supplied to the sterilizing water supply device 304 is detected by the current detection unit 308 and the current-voltage conversion unit 310. When the amount of current supplied to the sterilizing water supply device 304 is out of a preset range, the control unit 306 can control the magnitude of the voltage applied to the sterilizing water supply device 304 and exert a sterilizing effect. Ensure that the correct range of concentrations is maintained. That is, if an excessive amount of current is supplied to the sterilizing water supply device 304, the concentration of the silver solution becomes too high, and the laundry may be contaminated by the silver solution. Therefore, the amount of current is limited to prevent this.

図４Ａ及び図４Ｂは、本発明による殺菌洗濯機の殺菌水供給装置を示す断面図である。図４Ａに示すように、殺菌洗濯機に洗濯物が投入され、電源が供給された後、洗濯コースが設定されると、水槽１０４の内部に洗濯水が給水される。給水される洗濯水は洗剤溶解装置（図示せず）を経由しながら洗剤を溶解させ洗剤とともに水槽１０４の内部に給水される。   4A and 4B are cross-sectional views illustrating a sterilizing water supply device of a sterilizing washing machine according to the present invention. As shown in FIG. 4A, when the laundry is set in the sterilization washing machine and the power is supplied, the washing water is supplied into the water tank 104 when the washing course is set. The washing water to be supplied is dissolved in the water tank 104 together with the detergent by dissolving the detergent through a detergent dissolving device (not shown).

使用者が殺菌洗濯コースを洗濯した場合、このような給水動作と同時に、殺菌水供給装置３０４の入口バルブ２０４が開放され、貯蔵容器１２２の内部に水が給水される。貯蔵容器１２２の出口配管１２４の終端付近には温度センサ４００が取り付けられる。この温度センサ４００は、殺菌水供給装置３０４から洗濯槽１０６に給水される殺菌水の温度を検出するためのものである。＋極性の銀板２２０が酸化しながら発生した銀イオンが−電極の銀板２２０に付着せずに水に残留することにより銀溶液が作られる。温度センサ４００は、銀溶液の温度を検出して銀溶液殺菌水の濃度を判断する。   When the user washes the sterilization washing course, the inlet valve 204 of the sterilization water supply device 304 is opened simultaneously with the water supply operation, and water is supplied into the storage container 122. A temperature sensor 400 is attached near the end of the outlet pipe 124 of the storage container 122. This temperature sensor 400 is for detecting the temperature of the sterilizing water supplied from the sterilizing water supply device 304 to the washing tub 106. A silver solution is made by the silver ions generated while the positive polarity silver plate 220 is oxidized remaining in the water without adhering to the silver plate 220 of the negative electrode. The temperature sensor 400 detects the temperature of the silver solution and determines the concentration of the silver solution sterilizing water.

殺菌水供給装置３０４の２枚の銀板２２０、２２２に電源が印加されると、銀溶液殺菌水が製造される。この銀溶液殺菌水が洗濯槽１０６の内部に給水され洗濯物を殺菌する。すなわち、貯蔵容器１２２の入口２０２を通じて給水される水は、まず貯蔵容器１２２の第１空間２１０に満たされながら流速及び流れが安定するように整流され、第１空間２１０の水が第１仕切り２０６を越えて第２空間２１４側に流れる。そして、第１空間２１０を経て第２空間２１４に流入する水は第２仕切り２０８の高さに相当する水位で第２空間２１４に満たされ、第２空間２１４に水が満たされた後には第２仕切り２０８を越えて第３空間２２４に流れ、出口２１６を通じて洗濯槽１０６の内部に給水される。この際、第２空間２１４の水は一定量を維持したままで第３空間に流れる。この過程で、２枚の銀板２２０、２２２と水の電気分解により銀溶液殺菌水が製造され、製造された殺菌水が出口２１６を通じて洗濯槽１０６に給水される。このような殺菌水の製造動作は給水中に持続的に行われる。   When power is applied to the two silver plates 220 and 222 of the sterilizing water supply device 304, silver solution sterilizing water is produced. This silver solution sterilizing water is supplied into the washing tub 106 to sterilize the laundry. That is, the water supplied through the inlet 202 of the storage container 122 is first rectified so that the flow velocity and flow are stabilized while being filled in the first space 210 of the storage container 122, and the water in the first space 210 is rectified. Over to the second space 214 side. Then, the water flowing into the second space 214 through the first space 210 is filled in the second space 214 at a water level corresponding to the height of the second partition 208, and after the second space 214 is filled with water, It flows into the third space 224 beyond the two partitions 208 and is supplied into the washing tub 106 through the outlet 216. At this time, the water in the second space 214 flows into the third space while maintaining a constant amount. In this process, silver solution sterilized water is manufactured by electrolysis of the two silver plates 220 and 222, and the manufactured sterilized water is supplied to the washing tub 106 through the outlet 216. Such manufacturing operation of sterilizing water is continuously performed during the water supply.

殺菌水を製造する過程において、入口２０２に給水される水が多い場合には、貯蔵容器１２２の内部の水が放流配管１２８を通じて排水管１１８ａ側に流れるため、貯蔵容器１２２の内部水位を適正水位で維持することができ、よって常に一定濃度の銀溶液殺菌水を製造することができる。殺菌水製造動作が終了するときは、入口バルブ２０４が閉じて、貯蔵容器１２２への給水が中断されるとともに２枚の銀板２２０、２２２への電源印加も中断される。この際、内部に残存する水は二つの仕切り２０６、２０８の下部の残水排出孔２０６ａ、２０８ａを通じて出口２１６側に流れてすっかり排出される。   In the process of producing sterilizing water, when there is a lot of water supplied to the inlet 202, the water inside the storage container 122 flows to the drain pipe 118a side through the discharge pipe 128, so the internal water level of the storage container 122 is set to the appropriate water level. Thus, a silver solution sterilized water with a constant concentration can be produced at all times. When the sterilizing water production operation is finished, the inlet valve 204 is closed, the water supply to the storage container 122 is interrupted, and the power supply to the two silver plates 220 and 222 is also interrupted. At this time, the water remaining inside flows through the residual water discharge holes 206a and 208a below the two partitions 206 and 208 toward the outlet 216 and is completely discharged.

水槽１０４に、殺菌水を含む洗濯水が満たされた後、パルセーター１０８が回転しながら洗濯物の洗濯を行い、洗濯の過程で、殺菌水により細菌が滅菌される。   After the water tank 104 is filled with washing water containing sterilizing water, the laundry is washed while the pulsator 108 rotates, and bacteria are sterilized by the sterilizing water in the washing process.

殺菌水供給装置３０４は、２枚の銀板２２０、２２２に＋極性と−極性の電圧を交番に印加して水中で電気分解を行うことにより、陰イオンを発生させる。この際、銀イオンの発生量、つまり銀溶液の濃度は２枚の銀板２２０、２２２を通じて流れる電流量、或いは２枚の銀板２２０、２２２に印加される電圧の大きさに比例する。   The sterilizing water supply device 304 generates negative ions by applying positive and negative polarities alternately to the two silver plates 220 and 222 to perform electrolysis in water. At this time, the amount of silver ions generated, that is, the concentration of the silver solution, is proportional to the amount of current flowing through the two silver plates 220 and 222 or the magnitude of the voltage applied to the two silver plates 220 and 222.

図４Ｂは、本発明による殺菌洗濯機の殺菌水供給装置のほかの設置例を示すもので、温度センサ４５０を殺菌水供給装置３０４の入口２０２に設け、殺菌水供給装置３０４に流入する水の温度を測定する。   FIG. 4B shows another installation example of the sterilizing water supply device of the sterilizing washing machine according to the present invention. A temperature sensor 450 is provided at the inlet 202 of the sterilizing water supply device 304, and the water flowing into the sterilizing water supply device 304 is shown. Measure the temperature.

このように構成される本発明による殺菌洗濯機の制御方法を図５に基づいて説明する。図５に示すように、本発明による殺菌水の給水は、すすぎ行程の最終すすぎ段階のためにすすぎ水を給水するときに行われる。まず、洗濯モードが設定されると（５０２）、設定された洗濯モードにしたがって洗濯行程を実施した後（５０４）、すすぎ行程を始める（５０６）。すすぎ行程は、通常多数回にわたって実施されるが、毎回すすぎ水を給水し、洗濯槽１０６を正回転及び逆回転させて洗濯物をすすぐ。   A control method of the sterilization washing machine according to the present invention configured as described above will be described with reference to FIG. As shown in FIG. 5, the sterilizing water supply according to the present invention is performed when supplying the rinsing water for the final rinsing stage of the rinsing process. First, when the washing mode is set (502), the washing process is performed according to the set washing mode (504), and then the rinsing process is started (506). The rinsing process is usually performed a number of times. Rinse water is supplied each time, and the laundry is rinsed by rotating the washing tub 106 forward and backward.

すすぎ行程が進み（５０８）、最終のすすぎ段階に到達すると（５１０で「ＹＥＳ」）、最終すすぎ段階のためのすすぎ水の給水を開始する（５１２）。すすぎ水の給水が開始すると、温度センサ４００によりすすぎ水（殺菌水）の温度を検出する（５１４）。このような方法によりすすぎ水の温度が検出されると、検出された温度によって印加電圧の大きさを設定し、設定された大きさの電圧を殺菌水供給装置３０４の２枚の銀板２２０、２２２に印加する（５１６）。銀板２２０、２２２に電圧が印加されると、銀板２２０の酸化作用により、印加電圧に比例する濃度の殺菌水が製造され洗濯槽１０６内に給水される（５１８）。   When the rinsing process proceeds (508) and the final rinsing stage is reached ("YES" at 510), rinsing water for the final rinsing stage is started (512). When the rinsing water supply starts, the temperature sensor 400 detects the temperature of the rinsing water (sterilizing water) (514). When the temperature of the rinsing water is detected by such a method, the magnitude of the applied voltage is set according to the detected temperature, and the two silver plates 220 of the sterilizing water supply device 304 are set with the set voltage. The voltage is applied to 222 (516). When a voltage is applied to the silver plates 220 and 222, sterilizing water having a concentration proportional to the applied voltage is produced and supplied into the washing tub 106 by the oxidizing action of the silver plate 220 (518).

殺菌水供給装置３０４が動作して、殺菌水が給水され始めると、電流検出部３０８及び電流−電圧変換部３１０により、殺菌水供給装置３０４に供給される電流量を検出する（５２０）。検出された電流量が前もって設定された範囲より小さいと（５２２で「ＹＥＳ」）、制御部３０６では電圧制御信号３１４で駆動部３０２を制御して、殺菌水供給装置３０４に供給される電流量を増大させる（５２４）。この際、検出された電流量を比較する設定範囲は殺菌水である銀溶液が十分な殺菌効果を与えるとともに洗濯物が汚染しない濃度の銀溶液を製造するのに必要な電流量の範囲である。逆に、検出された電流量が設定範囲より大きいと（５２２で「ＮＯ」）、電流量を減少させて銀溶液の濃度を低める（５２６）。   When the sterilizing water supply device 304 operates to start supplying sterilizing water, the current detection unit 308 and the current-voltage conversion unit 310 detect the amount of current supplied to the sterilizing water supply device 304 (520). When the detected current amount is smaller than the preset range (“YES” at 522), the control unit 306 controls the drive unit 302 with the voltage control signal 314 to supply the sterilized water supply device 304 with the current amount. (524). At this time, the set range in which the detected current amount is compared is a range of the current amount necessary for producing a silver solution having a concentration such that the silver solution as sterilizing water provides a sufficient sterilizing effect and the laundry is not contaminated. . Conversely, when the detected current amount is larger than the set range (“NO” in 522), the current amount is decreased to lower the concentration of the silver solution (526).

すすぎ水の給水が完了すると（５２８で「ＹＥＳ」）、最終回のすすぎ段階を実施した後（５３０）、脱水行程を実施し（５３２）、洗濯を終了する。   When the rinsing water supply is completed (“YES” in 528), after the final rinsing stage is performed (530), a dehydration process is performed (532), and the washing is finished.
