Description
본 발명은 세탁기에 관한 것으로, 상세하게는 세탁수 생성장치를 구성하는 전해질방 하우징 일측에 세탁수의 수온을 측정하는 써모 커플을 설치하고, 상기한써모 커플의 작용에 의해 전원공급이 단속되는 전열히터를 설치하여 수온이 일정온도 이하로 저하될 경우에는 전열히터의 동작에 따라 수온을 상승시킴으로써 전해질의 용해를 촉진시키는 한편, 이에 따라 세탁효율을 높이도록 구성한 것이다.The present invention relates to a washing machine, and in particular, a thermocouple for measuring the water temperature of the washing water is installed on one side of the electrolyte room housing constituting the washing water generating device, and the heat supply is interrupted by the action of the thermo couple. If the water temperature is lowered below a certain temperature by installing a heater, the water temperature is increased in accordance with the operation of the heat transfer heater to promote the dissolution of the electrolyte, thereby increasing the washing efficiency.
일반적으로 가정용 세탁기는 세탁조에 투입된 세탁물이 세제가 함유된 세탁수와 함께 회전하는 과정에서 세제의 계면활성작용과 세탁조 내벽면과의 마찰이나 낙하에 따른 충격에 의해 세탁효과가 발생하며, 특히 펄세이터 방식의 세탁기에서는 세제의 계면활성작용과 펄세이터의 회전에 의해 형성된 수류에 의해 세탁이 이루어진다.In general, a washing machine in a household washing machine generates a washing effect due to the surfactant activity and the impact of friction or drop with the inner wall of the washing tank in the process of rotating the laundry into the washing tank together with the washing water containing the detergent. In particular, the pulsator In the washing machine of the type washing is performed by the water flow formed by the surfactant action of the detergent and the rotation of the pulsator.
이와 달리 최근에 개발된 세탁기에서는 세탁물에 대한 마찰력 및 낙하에 따른 충격이나 수류에 의한 세탁작용과 함께 특수한 구조의 전기분해 장치를 경유한 세탁수를 세탁 이온수로 전환시킴으로써 별도의 세제투입없이 세탁물의 오염물을 분해하고, 각종 세균의 살균이 이루어지도록 한다.On the other hand, in the recently developed washing machine, contaminants of laundry without the addition of detergent by converting the washing water through the electrolytic device of the special structure into the washing ion water with the frictional force and the washing action due to the impact or drop of the laundry. Decompose and sterilize various bacteria.
도 1은 상기한 무세제 세탁기에서 세탁수 생성장치의 원리를 도시한 개략도로서, 이와 같은 세탁수 생성장치는 내부에 이온교환막이 수직으로 설치되며, 상기한 이온교환막에 의해 구획된 세탁수방 및 전해질방의 내부에는 직류전압이 인가되는 전극이 각각 결합된다.1 is a schematic view showing the principle of the washing water generating device in the detergent-free washing machine, such a washing water generating device has an ion exchange membrane vertically installed therein, the laundry bag and the electrolyte partitioned by the ion exchange membrane Inside the room, electrodes to which a DC voltage is applied are respectively coupled.
이와 같은 세탁수 생성장치는 수도물과 같이 외부로부터 공급된 물에 NaCl, Na2CO3등의 전해질을 용해시킨 상태에서 전극의 극성에 따라 직류전압을 인가한다.Such a washing water generating device applies a DC voltage according to the polarity of an electrode in a state in which an electrolyte such as NaCl or Na 2 CO 3 is dissolved in water supplied from the outside, such as tap water.
상기한 바와 같이 직류전압이 인가되면, 전해질방에서는 전해질의 음이온 성분이 CO,CO2등의 가스로 방출되는 한편, O2가 생성되고, 세탁수방에서는 H2가 발생되어 전해질의 양이온 성분을 포함하고 있는 염기성의 세탁수가 형성되며, 이와 같은 양이온 성분은 섬유에 침투된 오염물질을 분리시켜 세탁이 이루어지도록 한다.As described above, when a DC voltage is applied, the anion component of the electrolyte is released as a gas such as CO or CO 2 in the electrolyte room, while O 2 is generated, and H 2 is generated in the laundry bag to include the cation component of the electrolyte. The basic wash water is formed, and such a cationic component separates the contaminants penetrated into the fiber so that washing is performed.
도 2는 상기한 원리를 적용한 무세제 세탁기의 세탁수 생성장치(200)를 도시한 분해 사시도로서, 이와 같은 세탁수 생성장치(200)는 망체 형상으로 이루어져 양극 및 음극의 전원이 각각 인가되는 장방형의 양전극판(130) 및 음전극판(150); 상기한 양전극판(130) 및 음전극판(150) 사이에 개재되며, 음이온 및 양이온만이 투과되도록 한 이온교환막(140) 및 수도물 및 세탁수가 저장되며, 상기한 양전극판(130) 및 음전극판(150)과 이온교환막(140)의 결합공간을 제공하는 전해질방 하우징(110) 및 세탁수방 하우징(120)을 주요구성으로 하여 이루어진다.Figure 2 is an exploded perspective view showing the washing water generating device 200 of the detergent-free washing machine applying the above principle, such a washing water generating device 200 is made of a mesh shape is a rectangular to which the positive and negative power is applied respectively The positive electrode plate 130 and the negative electrode plate 150; Interposed between the positive electrode plate 130 and the negative electrode plate 150, the ion exchange membrane 140 and the tap water and the wash water so that only anion and cation are permeated are stored, the positive electrode plate 130 and the negative electrode plate ( An electrolyte chamber housing 110 and a laundry immersion housing 120 providing a bonding space between the 150 and the ion exchange membrane 140 are mainly configured.
이와 같은 세탁수 생성장치(200)는 외부로부터 공급된 물에 전해질을 용해시킨 상태에서 양전극판(130) 및 음전극판(150)으로 각각 직류전압을 인가하여 수도물을 염기성의 세탁수로 전환시키며, 상기한 과정에서 세탁수방에 일정량의 수도물을 지속적으로 급수하는 동시에 양전극판(130) 및 음전극판(150)으로 직류전압을 인가하여 세탁수방으로부터 세탁수를 지속적으로 생성되도록 한다.The washing water generating device 200 converts tap water into basic washing water by applying a DC voltage to the positive electrode plate 130 and the negative electrode plate 150 in a state where the electrolyte is dissolved in water supplied from the outside. In the above process, a constant amount of tap water is continuously supplied to the washing bag and a DC voltage is applied to the positive electrode plate 130 and the negative electrode plate 150 to continuously generate the washing water from the washing bag.
한편, 통상적으로 세탁수에 공급되는 세탁용수로는 수도물이 사용되는데, 이와 같은 수도물은 하절기에는 20 내지 27℃의 수온을 갖는 반면, 동절기에는 5 내지 10℃의 수온을 갖는다.Meanwhile, tap water is generally used as washing water supplied to washing water, which has a water temperature of 20 to 27 ° C. in summer, and a water temperature of 5 to 10 ° C. in winter.
상기한 바와 같은 수온을 갖는 수도물은 하절기에는 전해질의 높은 용해도와함께 섬유로부터 오염물의 분리가 원활히 이루어지는 반면, 동절기에는 전해질의 용해도가 급격히 저하된다.Tap water having a water temperature as described above smoothly separates contaminants from fibers with high solubility of the electrolyte during the summer, while the solubility of the electrolyte rapidly decreases during the winter.
따라서 종래의 무세제 세탁기의 세탁수 생성장치(200)는, 저온의 수도물이 공급되는 동절기에서는 세탁률이 저하되는 한편, 용해되지 않은 전해질의 일부가 배수구(101) 주변에 포집되어 배수를 차단하거나 잔수의 배출에 장애를 줌으로써 양전극판(120)을 중심으로 전해질이 침착되어 세탁수의 생성에 장애가 발생하며, 양전극판(120)과 같은 내부 구성부품의 성능이 급격히 저하되는 등의 문제점이 따른다.Therefore, in the conventional washing machine generating apparatus 200 of the washing machine, the washing rate is lowered in the winter when low-temperature tap water is supplied, while a part of the electrolyte that is not dissolved is collected around the drain hole 101 to block drainage. By impeding the discharge of the residual water, the electrolyte is deposited around the positive electrode plate 120, thereby causing the generation of the wash water, and the performance of internal components such as the positive electrode plate 120 is rapidly lowered.

It is to provide a means to increase the efficiency.
상기한 바와 같은 본 발명의 기술적 과제는, 전해질방 하우징 및 세탁수방 하우징의 결합에 따라 형성된 공간 내부에 직류전압이 인가되는 양전극판 및 음전극판이 각각 결합되고, 상기 양전극판 및 음전극판 사이에는 이온교환막이 개재되는 무세제 세탁기의 세탁수 생성장치에 있어서,The technical problem of the present invention as described above, the positive electrode plate and the negative electrode plate to which the DC voltage is applied in the space formed by the combination of the electrolyte room housing and the wash-water housing is coupled, respectively, between the positive electrode plate and the negative electrode plate ion exchange membrane In the washing water generating device of the detergent-free washing machine,
상기 전해질방 하우징의 내벽 상부에는 수온을 측정하는 써모 커플을 설치하고, 상기 전해질방 하우징의 하부에는 상기 써모 커플로부터 감지된 수온에 따라 전원공급이 단속적으로 이루어지는 전열히터를 설치한 것을 특징으로 하는 무세제 세탁기의 세탁수 생성장치를 제공함으로써 달성된다.A thermocouple measuring water temperature is installed on the inner wall of the electrolyte chamber housing, and a heat transfer heater is installed on the lower portion of the electrolyte chamber housing in which power supply is intermittently supplied according to the water temperature sensed by the thermo couple. It is achieved by providing a washing water generating device of the detergent washing machine.
