[0022] The present application describes multiple embodiments, but the description is exemplary rather than restrictive, and it is obvious to those skilled in the art that there may be more embodiments and implementations within the scope of the embodiments described in the present application. Although many possible feature combinations are shown in the drawings and discussed in the specific embodiments, many other combinations of the disclosed features are also possible.

In addition, various modifications and changes may be made within the scope of protection of the attached claims.

[0024] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not rely on the specific order of the steps described herein, the method or process should not be limited to the steps of the specific order described. As will be understood by those of ordinary skill in the art, other sequences of steps are also possible. Therefore, the specific sequence of the steps set forth in the specification should not be interpreted as a limitation to the claims. In addition, the claims for the method and / or process should not be limited to the steps of performing them in the order written, and those skilled in the art can easily understand that these sequences can be changed and still remain within the spirit and scope of the embodiments of the present application.

[0025] In the related art, since there are pollutants in the condensed water generated by air handling equipment (such as air conditioners), in order to avoid the discharge of condensed water to the outside and causing environmental pollution, or using condensed water as a water source to cool the outdoor unit of the air conditioner and causing corrosion of the outdoor unit, an activated carbon adsorption module can be filled in the condensed water receiving tray to remove pollutants by activated carbon adsorption. However, the adsorption capacity of activated carbon is limited. After the activated carbon is saturated with adsorption, it needs to be replaced in time and is difficult to regenerate, which increases the cost of use. Moreover, the flow of condensed water passing through the receiving tray filled with activated carbon modules will create resistance to the flow of condensed water, making it difficult for the condensed water to flow out. More water or an additional water pump is required to provide assistance.

[0026] The embodiment of the present application provides a condensate purification device, such as Figure 1 and Figure 2 As shown, the water receiving tray 1 for receiving condensed water and the first electrode 21 and the second electrode 22 ( Figure 1 Only two side walls 11 of the water receiving tray 1 are shown in the figure. The first electrode 21 is configured to be connected to the first output pole of the power supply 3, and the second electrode 2 is configured to be connected to the second output pole of the power supply 3, so that pollutants in the condensed water can be adsorbed by the first electrode 21 and / or the second electrode 22.

[0027] The condensed water purification device provided in the embodiment of the present application can be applied to air treatment equipment such as air conditioners and dehumidifiers. After the first electrode 21 and the second electrode 22 are connected to the power supply 3, the anions and cations or polarity in the pollutants of the condensed water will gradually migrate to the electrode of a specific polarity after being polluted by the force of the electric field. For example, the first output pole of the power supply 3 can be a positive pole, and the second output pole of the power supply 3 can be a negative pole, and the anions can migrate to the first electrode 21, and the cations can migrate to the second electrode 22. The ions or polar pollutants are adsorbed by the electrodes, which can achieve the purpose of removing pollutants and purifying condensed water. The purification method of the condensed water is simple and effective. The purified condensed water can be directly discharged to the external environment without polluting the environment, and can also be used to cool the outdoor unit of the air conditioner.

[0028] In addition, the solution provided in the embodiments of the present application has the advantages of small flow resistance of condensed water compared to the above-mentioned method of filling activated carbon to adsorb pollutants. After the ions adsorbed on the electrode surface reach saturation, the ions can be removed by cleaning the electrode, etc., to achieve electrode regeneration, and there is no need to replace consumables.

[0029] In order to enable the electrodes to adsorb more pollutant ions, at least one of the first electrode 21 and the second electrode 22 is configured to include an adsorption material having the advantages of large adsorption capacity, good regeneration effect, and low price and easy availability. The adsorption material can be one or more of activated carbon, graphene, and carbon aerogel. Of course, other adsorption materials can also be used.

[0030] In one embodiment, at least one of the first electrode 21 and the second electrode 22 includes an electrode body and an adsorption material attached to the outside of the electrode body, wherein the electrode body may be made of a metal material with good electrical conductivity, such as copper.

[0031] In some embodiments, when the adsorption material is conductive, the first electrode 21 and the second electrode 22 may be completely composed of the adsorption material.

[0032] It is understandable that the environment in which the air treatment equipment (such as an air conditioner) is located is different, and there will be different pollutants in the condensed water produced. According to the type of pollutant, the adsorbent material can be set only on one of the first electrode 21 and the second electrode 22, or the adsorbent material can be set on both. For example, in a household air conditioner, due to human metabolism, life emissions (kitchen cooking, aromatherapy) and other reasons, there is a certain concentration of small molecule acids in the indoor air, so the pollutants in the condensed water mainly include acid radical ions, and the negative ions such as acid radical ions are mainly removed. Therefore, the adsorbent material can be set only on the first electrode 21 connected to the positive electrode. In some environments, if the pollutant is mainly in the form of cations, the adsorbent material can be set only on the second electrode 22 connected to the negative electrode. In some environments, the pollutant molecules have polarity, and the group part with larger electronegativity is easily attracted by the first electrode 21 connected to the positive electrode, and the adsorbent material can be set only on the first electrode 21 connected to the positive electrode.

[0033] In some embodiments, a plurality of first electrodes 21 are provided, and the plurality of first electrodes 21 can be connected to the positive electrode of the power supply through a plurality of branch wires, and / or a plurality of second electrodes 22 are provided, and the plurality of second electrodes 22 can be connected to the negative electrode of the power supply through a plurality of branch wires. The number of the first electrode 21 and the second electrode 22 determines the effective adsorption area of ​​the electrode. The larger the number, the larger the adsorption area. The number of the first electrode 21 and the second electrode 22 can be set to be the same or different according to the type of pollutants and the degree of pollution of the pollutants. In the case where there are more negative ions in the pollutants, the number of the first electrode 21 can be set to be greater than the second electrode 22, and in the case where there are more positive ions in the pollutants, the number of the second electrode 22 can be set to be greater than the first electrode 21.

[0034] like Figure 1 and Figure 2In the example shown, the first electrodes 21 and the second electrodes 22 are each arranged in a row, and the plurality of first electrodes 21 and the plurality of second electrodes 22 are arranged in a staggered manner, that is, in the arrangement direction, each first electrode 21 is arranged at a position between two adjacent second electrodes 22, and each second electrode 22 is arranged at a position between two adjacent first electrodes 21. The staggered arrangement of the plurality of first electrodes 21 and the plurality of second electrodes 22 can make the first electrodes 21 and the second electrodes 22 more evenly distributed in the water receiving tray, thereby more effectively adsorbing pollutants.

[0035] After the electrode adsorbs pollutants for a period of time, the ions adsorbed on the electrode surface will reach saturation, and the electrode can be removed for cleaning to remove ions. To this end, the first electrode 21 and the second electrode 22 can be detachably mounted on the water receiving tray 1.

[0036] In some embodiments, the first electrode 21 and the second electrode 22 are respectively mounted on the side walls 11 on opposite sides of the water receiving tray 1, and an electrode mounting structure 12 can be provided on the side wall 11 for detachably mounting the electrodes. For example, a plug hole or mounting groove is provided on the side wall 11, and the electrodes can be installed by inserting the electrodes into the plug holes on the side wall 11 or clamping them in the mounting grooves.

[0037] In some embodiments, the first electrode 21 and the second electrode 22 may also be respectively installed on the bottom surface of the water receiving tray 1. A mounting groove may be provided on the bottom surface of the receiving tray, and the electrodes may be clamped in the mounting groove.

[0038] exist Figure 1 and Figure 2 In the example shown, the first electrode 21 and the second electrode 22 are respectively plate-shaped, such as long strip-shaped structures, and their plate-shaped planes themselves are arranged vertically to the bottom surface of the water receiving tray 1. The length direction of the first electrode 21 and the second electrode 22 can be arranged in the water receiving tray 1 along the horizontal direction. The first electrode 21 and the second electrode 22 are respectively plate-shaped, such as long strip-shaped structures, which can increase the adsorption area, and the plate-shaped planes of each electrode are arranged vertically to the bottom surface of the water receiving tray 1. When the length direction of each electrode is arranged horizontally in the water receiving tray 1, each part of the electrode along the length can be in contact with the condensed water. Usually, each electrode can be arranged at the bottom of the water receiving tray 1 or near the bottom.

[0039] After the condensed water drips into the water receiving tray 1, it usually flows from the water receiving tray 1 into the drain pipe or water guiding mechanism. To this end, the water receiving tray 1 is configured so that the condensed water contained therein can flow between the opposite side walls 11 in a predetermined direction (as shown in the direction of the arrow in the figure) so as to flow into the drain pipe or water guiding mechanism in a predetermined direction. The condensed water is further discharged or flows to the water collecting tank for subsequent humidification and cooling.

[0040] exist Figure 1In the example shown, the first electrode 21 and the second electrode 22 are respectively installed on the side walls 11 on both sides and are inclined relative to the side walls 11. The first electrode 21 and the second electrode 22 are staggered with each other and the ends close to each other are both facing the predetermined direction. In this example, the electrodes are tilted and staggered on the water receiving tray 1, so that the electrodes can fully contact with the condensed water, and the flow rate of the water flow along the predetermined direction can be slightly reduced, thereby increasing the electrical adsorption time to more fully adsorb the pollutants.

[0041] exist Figure 2 In the example shown, the length directions of the first electrode 21 and the second electrode 22 are arranged along a predetermined direction, and the first electrode 21 and the second electrode 22 are respectively attached to the two side walls 11 of the water receiving tray 1 .

[0042] Figure 1 and Figure 2 In the example shown, the side wall 11 of the water receiving tray 1 is provided with an electrode mounting structure 12, and the electrode can be assembled and disassembled from the electrode mounting structure 12 by plugging and unplugging. Figure 1 In the embodiment, the electrode is installed in an inclined manner, which is suitable for a water tray 1 having a certain width. For example, the water tray on a household air conditioner cabinet is relatively wide, and the electrode can be installed in an inclined manner. Figure 1 The tilted installation method shown in the figure; the water tray of the household air conditioner is long and narrow, so the electrode can be installed in Figure 2 Install it close to the side wall of the water tray as shown in .

[0043] When the first electrode 21 or the second electrode 22 includes an adsorption material attached to the outside of the electrode body, the adsorption material may be provided on a surface of the electrode body facing upstream in a predetermined direction.

[0044] The ability to treat pollutants in the condensed water is related to the adsorption area of ​​the adsorption material on the first electrode 21 and the second electrode 22, the adsorption capacity of the material, and the potential applied between the first electrode 21 and the second electrode 22. The effective adsorption area of ​​the electrode and the application of a suitable potential between the first electrode 21 and the second electrode 22 can be set according to factors such as the properties of the electrode material and the degree of contamination of the condensed water.

[0045] The length and number of electrodes arranged in the water receiving tray 1 are related to the adsorption area. If the effective adsorption area is too low, the ability to treat pollutants in the condensed water is insufficient; if the effective adsorption area is too high, it will waste resources and increase costs. While ensuring that the pollutants are completely treated, the number, length and spacing between adjacent electrodes can be reasonably arranged according to the size of the water receiving tray 1.

[0046] According to the area of ​​the common water tray 1 of the household air conditioner, it is better to set 4-8 electrodes on one side, and the length of each electrode is controlled between 90-200mm. The potential applied between the first electrode 21 and the second electrode 22 is generally in the range of 0.4-0.8V.

[0047] In one example, the carboxylate ion concentration in the condensed water produced by a household air conditioner is 0.3 mg / L, and the sulfate ion concentration is 0.5 mg / L. The adsorption material used by the first electrode 21 and the second electrode 22 is carbon black. There are three electrodes on each side of the water receiving tray 1, each with a length of 150 mm. The applied potential is 0.65 V, which can effectively purify the condensed water. After the condensed water purification device has been running for 670 hours, the ions adsorbed on the electrode surface have reached saturation, and the electrodes need to be removed for cleaning and deionization.

[0048] The embodiment of the present application further provides an air treatment device, comprising the condensed water purification device as described above, wherein the air treatment device may be an air conditioner or a dehumidifier.
