BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a dishwasher according to an embodiment of the present invention will be described with reference to the drawings.
[0015]
(1st Embodiment)
The dishwasher 1 of the present embodiment has an electrolyzed water generating means 2, a dishwashing means 3, an electrolyzed water injection means 4, and an electrolyzed water generating means, as shown in FIG. 2, a control device 5 including a CPU as a control means for controlling the dishwashing means 3, the electrolyzed water injection means 4, and the like.
[0016]
The electrolyzed water generating means 2 is for generating electrolyzed water by electrolyzing tap water. The electrolyzed water generating means 2 is installed at the bottom of the dishwasher 1, and an electrolyzer 21 into which tap water is introduced. The device includes a pair of first and second electrodes 22 and 23 opposed to each other in the inside 21, and voltage applying means 24 for applying a voltage to the first and second electrodes 22 and 23.
[0017]
The electrolytic cell 21 is a container made of a resin material or the like resistant to alkali and acid. The electrolytic tank 21 stores tap water supplied from a later-described tap water tap via a supply water pipe and electrolytic water generated by electrolyzing the tap water, and is sprayed from a washing nozzle described later. Electrolyzed water and the like as the washed water thus collected are collected.
[0018]
The other end of the supply water pipe 26 having one end connected to the tap water tap 25 is connected to the electrolytic tank 21, and tap water from the tap water tap 25 is introduced into the electrolytic tank 21 through the supply water pipe 26. It has become so. A first solenoid valve (relief valve) 27 controlled by the control device 5 is provided in the middle of the supply water pipe 26, and a flow sensor is provided between the first solenoid valve 27 and the electrolytic cell 21. (Not shown) are provided. This flow sensor is a flow sensor that detects whether tap water is flowing through the electrolytic cell 21 and outputs a flow signal to the control device 5 as flow information.
[0019]
The first electrode 22 and the second electrode 23 facing and disposed in the electrolytic cell 21 are made of magnesium.
[0020]
The voltage applying means 24 is controlled by the control device 5 so as to apply a voltage to the first electrode 22 and the second electrode 23 when the water flow signal from the flow sensor is on. Specifically, a high potential voltage (for example, DC 24 V) is applied to the first electrode 22 side and a low potential voltage (DC 0 V) is applied to the second electrode 23 side for a certain time (for example, 5 minutes). For example, a low potential voltage (DC 0 V) is applied to the second electrode 23 side, and a high potential voltage (DC 24 V) is applied to the second electrode 23 for a certain period of time (for example, 5 minutes). Control is performed so that the polarity is alternately switched.
[0021]
In addition, since the electrolysis performance fluctuates depending on conditions such as the quality of tap water, the voltage applied to the first electrode 22 and the second electrode 23 is controlled by the control device 5 to stabilize the performance, and the inside of the electrolysis tank 21 is controlled. A mechanism for keeping the flowing current constant may be provided.
[0022]
Further, a heater 28 for heating the cleaning water in the electrolytic bath 21 is provided in the electrolytic bath 21. The heater 28 is also controlled by the control device 5.
[0023]
The dishwashing means 3 includes a washing tank 31 installed above the electrolytic tank 21, a dish basket 33 accommodated in the washing tank 31, and accommodating tableware 32, and spraying washing water onto the tableware 32. The cleaning nozzle 34 is provided.
[0024]
The washing tank 31 and the dish basket 33 are made of a resin material or the like resistant to alkalis and acids. The bottom of the washing tank 31 is formed of a filter 35 for collecting solid food residues and the like.
[0025]
A plurality of the washing nozzles 34 are provided uniformly above the washing tank 31 so that the washing water is sprayed uniformly on the dishes 32 stored in the dish basket 33. The other end of a circulation pipe 36 is connected to the washing nozzle 34 as a pipe having one end connected to the electrolytic cell 21. A cleaning pump 37 as a pressure feeding means is provided on the upstream side of the circulation pipe 36 (on the side of the electrolytic cell 21), and on the downstream side of the circulation pipe 36 (on the side of the cleaning nozzle 34). Detergent supply means 38 for supplying a predetermined amount of detergent is provided.
[0026]
The detergent supply means 38 is composed of an accommodation diagram (not shown) for accommodating the detergent at an upper portion and a measuring device (not shown) provided at a lower portion, and has a predetermined amount measured by the measuring device. The detergent is supplied to the cleaning nozzle 34. In addition, the user may measure a predetermined amount of detergent every time and then put the detergent into the storage unit without a measuring unit as a simple type.
[0027]
The cleaning pump 37 and the detergent supply means 38 are also controlled by the control device 5.
[0028]
Thus, the electrolyzed water or the like (tap water or electrolyzed water generated by the electrolyzed water generating means 2) stored in the electrolysis tank 21 is supplied to the cleaning nozzle 34 via the circulation pipe 36 by the pump pressure of the cleaning pump 37. The washing nozzle 34 is sprayed toward the tableware 32. Then, the electrolytic water or the like sprayed from the cleaning nozzle 34 and contaminated by cleaning the tableware 32 or the like is collected in the electrolytic cell 21 after the food residue and the like are removed by the filter 35. .
[0029]
The electrolyzed water injection means 4 includes an injection nozzle 41 and a second solenoid valve (three-way valve) disposed downstream of the cleaning pump 37 (upstream of the detergent supply means 38) in the middle of the circulation pipe 36. ) 42 and an injection hose 43 as a connection pipe having one end connected to the injection nozzle 41 and the other end connected to the second solenoid valve 42.
[0030]
The second solenoid valve 42 is controlled by the control device 5. The control of the second electromagnetic valve 42 by the control device 5 allows the electrolytic water or the like in the electrolytic cell 21 to be alternatively supplied to the cleaning nozzle 34 side or the injection nozzle 41 side, or the electrolytic water or the like in the electrolytic cell 21 Can be supplied to both the cleaning nozzle 34 side and the ejection nozzle 41 side.
[0031]
The injection hose 43 is a bellows-type hose that is made of a resin material or the like that is resistant to alkalis and acids and that can be elastically deformed, and that can freely expand and contract and change directions.
[0032]
The dishwasher 1 is provided with an operation panel (not shown) provided with various mode switches for selecting an operation mode for performing dishwashing and electrolytic water injection. The operation modes include a dishwashing mode and an electrolytic water injection mode. In the dishwashing mode, for example, there are various operation modes of pre-washing, main washing (with and without detergent), rinsing and drying, and a switch for indicating each operation mode, and pre-washing, main washing, and rinsing. And an automatic switch for automatically operating in the order of drying. The switch for instructing the electrolytic water injection mode is provided separately from the switch for instructing the dishwashing mode. Therefore, the electrolytic water injection mode can be operated independently or simultaneously with the dishwashing mode separately from the dishwashing mode.
[0033]
In the control device 5 to which these operation signals are input, the first electromagnetic valve 27, the voltage application means 24, the heater 28, the cleaning pump 37, the detergent supply means 38, the second electromagnetic valve 42 and the like are controlled.
[0034]
Hereinafter, the operation of the dishwasher of the present embodiment will be described.
[0035]
First, among the dishwashing modes, a control process of the control device 5 for sequentially performing preliminary washing and main washing (with detergent) will be described. This is performed, for example, when the amount of dirt attached to the tableware 32 is large.
[0036]
When the operation mode is the preliminary washing, the dishwashing is performed without using the detergent while using the electrolytic water as the washing water. First, the first solenoid valve 27 is opened so that tap water is introduced into the electrolytic cell 21. Next, a voltage is applied to the voltage applying means 24 by a water flow signal from a flow sensor (not shown) to apply a voltage to the first electrode 22 and the second electrode 23. Thereby, the tap water between both electrodes 22 and 23 is electrolyzed as shown below.
[0037]
Incidentally, the polarity of the voltage applied between the two electrodes 22 and 23 is switched every predetermined time (for example, 5 minutes). However, for convenience of explanation, the first electrode 22 is in the state of the anode and the second electrode 23 is in the state of the cathode. As an example, a chemical reaction of electrolytic water generation by electrolysis will be described.
[0038]
When a voltage is applied to the first electrode 22 and the second electrode 23, Mg is applied from the first electrode 22 on the anode side (high potential side). ²⁺ The ions dissolve in the water. Then, as shown in the following chemical reaction formula (1), Mg ²⁺ Ion is OH ⁻ Mg (OH) reacts with ions ₂ Is generated, and the tap water in the electrolytic cell 21 is reformed to be alkaline.
[0039]
Mg ²⁺ + 2OH ⁻ → Mg (OH) ₂ … (1)
Then, if necessary, the heater 28 is operated to heat the alkaline electrolyzed water in the electrolyzed water 21 to a predetermined temperature. The heating by the heater 28 may be performed simultaneously with the generation of the electrolytic water. Thereafter, the cleaning pump 37 is operated to supply the alkaline electrolyzed water in the electrolytic cell 21 to the circulation pipe 36.
[0040]
At this time, when the operation mode of the electrolyzed water injection is not operating, in the second solenoid valve 42, the passage on the injection nozzle 41 side is closed, and only the passage on the cleaning nozzle 34 side is open. Therefore, all the electrolytic water supplied from the electrolytic tank 21 to the circulation pipe 36 is sent to the cleaning nozzle 34 side. In this way, the alkaline electrolyzed water is sprayed from the cleaning nozzle 34 onto the tableware 32, and dirt such as oils and fats and proteins adhered to the tableware 32 are separated and removed by the alkaline electrolyte having a strong cleaning effect.
[0041]
Here, when the alkaline electrolyzed water is used simultaneously with the detergent, the detergency of the detergent is reduced. Therefore, in the present embodiment, in the case of main washing using a detergent, tap water is used as washing water without using alkaline electrolyzed water as washing water. That is, even if the first solenoid valve 27 is opened and the flow signal from the flow sensor (not shown) is an ON signal, the voltage application means 24 is not energized, and the heater 28 is heated to a predetermined temperature as necessary. The supplied tap water is supplied to the circulation pipe 36 by operating the washing pump 37 as it is. At this time, the detergent supply means 38 is operated to supply a predetermined amount of detergent to the cleaning nozzle 34. Thus, the washing water in which the detergent is mixed with the tap water is jetted from the washing nozzle 34, and the dishwashing with the detergent is performed.
[0042]
On the other hand, when the amount of dirt attached to the tableware 32 is small, only the main washing (without detergent) is performed. The main washing without using the detergent basically operates in the same manner as the preliminary washing described above.
[0043]
Thus, in the dishwasher 1 of the present embodiment, by using the alkaline electrolyzed water having a strong cleaning effect as the cleaning water, it is possible to reduce the amount of detergent used and to shorten the cleaning time. Can be. Also, by reducing the amount of detergent used, it is possible to reduce the environmental load on wastewater.
[0044]
Further, for example, according to the stains on the dishes 32, the tableware 32 is washed with tap water when using a detergent and with alkaline electrolyzed water when not using a detergent. Can be prevented from deteriorating, and efficient use of detergent can be achieved.
[0045]
Further, when the above-described electrolysis is continuously operated, Mg and Ca contained in the first and second electrodes 22 and 23 and tap water are precipitated on the electrode surface. In this embodiment, the polarity of the voltage applied to the first and second electrodes 22 and 23 is alternately switched to energize, although the surface becomes rough and the elution of Mg becomes uneven and the surface state is impaired. By doing so, roughness of the electrode surface can be prevented, and consumption of magnesium can be made uniform between the two electrodes 22 and 23, so that the life of the first and second electrodes 22, 23 can be extended.
[0046]
Next, the electrolytic water injection mode will be described. As described above, this electrolyzed water injection mode can be operated independently or simultaneously with the dishwashing mode separately from the dishwashing mode.
[0047]
First, a case where only the electrolytic water injection mode is operated independently of the dishwashing mode will be described. In this case, the first solenoid valve 27 is first opened so that tap water is introduced into the electrolytic cell 21 as in the pre-washing mode. Next, a voltage is applied to the voltage applying means 24 to apply a voltage to the first electrode 22 and the second electrode 23 by a water flow signal from a flow rate sensor (not shown), and the tap water in the electrolytic cell 21 is reformed into alkaline electrolytic water. I do.
[0048]
Then, if necessary, the heater 28 is operated to heat the alkaline electrolyzed water in the electrolyzed water 21 to a predetermined temperature. The heating by the heater 28 may be performed simultaneously with the generation of the electrolytic water. Thereafter, the cleaning pump 37 is operated to supply the alkaline electrolyzed water in the electrolytic cell 21 to the circulation pipe 36.
[0049]
At this time, when only the electrolyzed water injection mode is operated alone, in the second solenoid valve 42, the passage on the cleaning nozzle 34 side is closed, and only the passage on the injection nozzle 41 side is open. Therefore, all the electrolytic water supplied from the electrolytic tank 21 to the circulation pipe 36 is sent to the injection nozzle 41 side. Thus, the electrolyzed water is injected from the injection nozzle 41 through the injection hose 43. At this time, since the injection hose 43 is formed of a flexible bellows-type hose that can freely expand and contract and change directions, the injection position and the injection direction of the injection nozzle 41 can be arbitrarily determined. Therefore, a sink, a residue basket, and the like outside the dishwasher 1 can be easily washed.
[0050]
On the other hand, when simultaneously operating the electrolytic water injection mode during the operation of the dishwashing mode, the passage on the cleaning nozzle 34 side and the injection nozzle 41 in the second valve solenoid valve 42 are controlled by the control device 5. Both the side passages are opened so that the electrolytic water supplied from the electrolytic tank 21 to the circulation pipe 36 is supplied to both the cleaning nozzle 34 side and the injection nozzle 41 side. Thus, the electrolytic water can be simultaneously sprayed from both the washing nozzle 34 and the spray nozzle 41, and the washing of the tableware 32 and the washing of the sink outside the machine can be performed at the same time.
[0051]
As described above, in the dishwasher 1 of the present embodiment, not only the alkaline electrolyzed water generated by the electrolyzed water generating means 2 is used for washing the dishes 32 in the dishwasher 1, but also the dishwasher 1 is used. It can also be used to wash outside sinks. Therefore, according to the present embodiment, it is possible to improve the cost performance of the dishwasher 1 for washing dishes using electrolytic water.
[0052]
In this embodiment, an example in which the connection pipe is constituted by the injection hose 43 alone and the base end side of the injection hose 43 is directly connected to the second solenoid valve 42 is described. A connection pipe may be formed from the hose 43, one end of the connection pipe may be connected to the second solenoid valve 42, and the other end of the connection pipe may be connected to the base end of the injection hose 43.
[0053]
(2nd Embodiment)
The dishwasher 1 of the present embodiment is different from the first embodiment in that the configuration of the electrolyzed water injection means 4 is changed as shown in FIG. It is. The components having the same configuration as the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0054]
That is, the electrolytic spraying means 4 in the dishwasher 1 includes a spray nozzle 41, a connection pipe 44 made of a rigid body or the like having one end connected to the electrolytic tank 21, and an injection pump 45 arranged in the middle of the connection pipe 44. And an injection hose 43 having one end connected to the injection nozzle 41 and the other end connected to the other end of the connection pipe 44. In this embodiment, a connection pipe is constituted by the connection pipe 44 and the injection hose 43.
[0055]
In the dishwasher 1, when it is desired to operate the electrolytic water injection mode, the injection pump 45 controlled by the control device 5 is operated to connect the electrolytic water in the electrolytic tank 21 with the connection pipe 44 and the injection hose 43. And can be supplied to the injection nozzle 41 via the nozzle. Therefore, the dishwasher 1 of the present embodiment has the same functions and effects as those of the first embodiment.
[0056]
(Other embodiments)
In the above embodiment, an example in which a pair of the first electrode 22 and the second electrode 23 made of magnesium is used has been described, but the electrode mode is not limited to this.
[0057]
<Other electrode mode 1>
For example, a conductive metal such as a Pt-Ti alloy can be used for the first electrode 22 and the second electrode 23.
[0058]
When a pair of electrodes made of a conductive metal such as a Pt—Ti alloy is provided in the electrolytic cell 21 as described above, the anode of the first electrode 22 and the second electrode 23 has chlorine in tap water. By electrolyzing the ions, hypochlorous acid (HClO) having a strong antibacterial and deodorizing effect is generated.
[0059]
That is, as shown in the following chemical reaction formula (2), hydroxide ions (OH ⁻ ) Is decomposed to relatively hydrogen ions (H ⁺ )) As the concentration increases, strongly acidic water is generated, and as shown in the following chemical reaction formulas (3) and (4), chloride ions (Cl ⁻ ) Is once chlorine gas (Cl ₂ ), And reacts with water to produce antimicrobial component hypochlorous acid (HClO). Strong antibacterial and deodorizing effects can be obtained by the strongly acidic water and hypochlorous acid (HClO) thus generated.
[0060]
4OH ⁻ + 4e ⁺ → O ₂ ↑ + H ₂ O ... (2)
2Cl ⁻ + 2e ⁺ → Cl ₂ …… (3)
H ₂ O + Cl ₂ → HCl + H ⁺ + Cl ⁻ … (4)
In the vicinity of the electrode on one cathode side, as shown in the following chemical reaction formula (5), hydrogen ions (H ⁺ ) Is hydrogen gas (H ₂ ) And relatively decomposed into hydroxide ions (OH ⁻ ) Is increased to produce alkaline electrolyzed water.
[0061]
2H ⁺ + 2e ⁻ → H ₂ …… (5)
When a conductive metal such as a Pt-Ti alloy is used for the first electrode 22 and the second electrode 23, electrolyzed water containing hypochlorous acid having a strong antibacterial and deodorizing effect can be obtained. For this reason, in the dishwasher 1, it is possible to antibacterialize and deodorize the tableware 23, and at the same time, antibacterialize and deodorize a portion where the electrolytic water circulates, such as the tableware basket 33, the filter 35, and the electrolytic tank 21. Also, by spraying the electrolyzed water containing hypochlorous acid having a strong antibacterial and deodorizing effect from the injection nozzle 41, it is possible to antibacterial and deodorize a predetermined portion outside the machine.
[0062]
<Other electrode mode 2>
In addition, magnesium can be used for the first electrode 22 and a conductive metal such as a Pt-Ti alloy can be used for the second electrode 23.
[0063]
At this time, when the polarity of the voltage applied to the first and second electrodes 22 and 23 is switched under the control of the control device 5 to conduct the current, the first electrode 22 made of magnesium has the polarity on the anode side. , From the first electrode 22 ²⁺ Since the ions are dissolved, alkaline electrolytic water can be obtained. On the other hand, when the second electrode 23 made of a conductive metal such as a Pt—Ti alloy has a polarity on the anode side, chlorine ions (Cl ⁻ ) Is once chlorine gas (Cl ₂ ), And reacts with water to produce hypochlorous acid, so that electrolyzed water containing hypochlorous acid can be obtained.
[0064]
<Other electrode mode 3>
Further, a pair of first and second electrodes 22 and 23 made of magnesium may be used, and a pair of third and fourth electrodes made of a conductive metal such as a Pt-Ti alloy may be used. In this case, under the control of the control device 5, the first and second electrodes 22 and 23 can be energized, or the third and third electrodes can be energized to select the first and second electrodes. When the two electrodes 22 and 23 are energized, alkaline electrolyzed water can be obtained, and when the third and fourth electrodes are energized, electrolyzed water containing hypochlorous acid can be obtained.
[0065]
<Other electrode mode 4>
In addition, a plurality of pairs of the first electrodes 22 and the second electrodes 23 are stacked, or three or more first electrodes 22 and three or more second electrodes 23 are alternately arranged as shown in FIG. They can also be laminated. In this case, Mg from the anode side ²⁺ Dissolution of ions is increased, and high-concentration alkaline electrolyzed water can be obtained. For this reason, the detergency can be improved and the capacity of the electrolytic generation means can be reduced.
[0066]
<Other electrode modes 5>
Further, as shown in FIG. 4, one or a plurality of intermediate electrodes 29 are provided between the pair of first electrodes 22 and the second electrodes 23, and metal ions are dissolved in water from the intermediate electrodes 29, and alkaline electrolysis is performed. Water may be generated. In this case, since the total area of the electrodes can be increased, the dissolution of metal ions from the anode side increases, and a high-concentration alkaline electrolyte can be obtained. For this reason, the detergency can be improved and the capacity of the electrolytic generation means can be reduced.
[0067]
At this time, when a plurality of intermediate electrodes 29 are arranged between the first electrode 22 and the second electrode 23, the electric resistance between the first electrode 22 and the second electrode 23 increases as the number of the intermediate electrodes 29 increases, It becomes difficult for current to flow. Therefore, a plurality of combinations composed of the first electrode 22, the second electrode 23, and a small number of intermediate electrodes 29 may be stacked. For example, as shown in FIG. 5, one second electrode 23 is provided between the two first electrodes 22, 22, and between each of the first electrodes 22, 22 and the second electrode 23. If one intermediate electrode 29 is provided, it is possible to suppress an increase in the electric resistance between the first electrode 22 and the second electrode 23 due to the intermediate electrode 29.
[0068]
