It can be understood that the cloth 500 is hung on the uppermost airing bar 300 to naturally hang down and contact the airing bar 300 located below, so that when the drying rack is operated, moisture in the cloth 500 can be electrolyzed, and simultaneously, the moisture in the cloth 500 flows down in the cloth 500 due to gravity, thereby improving drying efficiency. Specifically, the plurality of positive electrode rods 310 and the plurality of negative electrode rods 320 in the present embodiment are staggered, so as to achieve the purpose of uniformly drying the cloth 500.

In another embodiment, referring to fig. 2 and 3, a plurality of sets of electrolytic bars are arranged in a horizontal direction. It can be understood that the placement layer formed by the plurality of airing bars 300 is horizontally arranged, so, when the cloth fabric 500 is placed on the placement layer, even if the length of the cloth fabric 500 exceeds the length of the placement layer, the placement state of the cloth fabric 500 can be adjusted, so that the cloth fabric 500 forms wrinkles at local positions, or the cloth fabric 500 is wound on the plurality of airing bars 300, the cloth fabric 500 is ensured to be completely in the placement layer, and the length of a drying loop in the cloth fabric 500 is improved, so that the water in most of the cloth fabric 500 can be electrolyzed, and a better drying effect is achieved. Specifically, in this embodiment, the plurality of positive rods 310 and the plurality of negative rods 320 are staggered, and the spacing between the adjacent airing rods 300 is smaller, so as to promote the contact between the cloth fabric 500 and the plurality of groups of electrolysis rods, reduce the control part in the cloth fabric 500, and promote the drying effect.

In one embodiment, one positive electrode rod 310 and one negative electrode rod 320 form a group of electrolytic rod groups, the drying rack is provided with a plurality of placement layers in the vertical direction, any one placement layer is provided with a plurality of groups of electrolytic rod groups, and the groups of electrolytic rod groups of the placement layers of the same layer are arranged in parallel. Without loss of generality, the electrical control 200 can independently control the power-on state of any one of the placement layers, so that the drying rack can simultaneously dry a plurality of cloth pieces 500 to improve the drying efficiency. In other embodiments, the drying rack may form multiple discharge racks in a horizontal direction, where any rack is provided with multiple groups of electrolysis rod groups, and multiple groups of electrolysis rod groups in the same rack are arranged in parallel. Specifically, the airing rod 300 may be in a straight state or may be in a curved arc state.

In an embodiment, referring to fig. 1 to 3, the electrical control 200 is provided with an adapter, and the electrical control 200 can be connected to an external power source, and the adapter is used for adjusting the voltage value of the external power source to be within a safe voltage range. It should be noted that, the desiccant in this embodiment is mainly applied in a home environment, that is, the voltage value of the external power source is 220V, so the adapter can adjust the voltage value of the external power source to be within 36V, and adjust the alternating current to be direct current, so as to ensure that the voltage on the air-drying rod 300 is within the range of safe voltage, and avoid false triggering of safety accidents by users, specifically, because the voltage of the electrolyzed water needs to be greater than 1.23V generally, the voltage range after the adapter conversion will be between 1.23V and 36V, that is, the stable electrolyzed water can be ensured, and the safety accidents of electric shock can also be avoided. Of course, in other embodiments, an openable and closable housing may be provided on the support 100, and when the cloth 500 is hung on the airing rod 300, a drying circuit is turned on after the housing is closed to dry the cloth 500, and further, a collecting device may be provided on the housing to collect the electrolyzed hydrogen and oxygen.

It can be understood that after the cloth 500 in the wet state is placed on the airing rod 300, the cloth 500 in the wet state is easy to drip, and the electric control member 200 is disposed above the airing rod 300, so that the dripping of the cloth 500 to the electric control member 200 can be avoided, and the water inlet of the electric control member 200 is damaged. In addition, referring to fig. 1 and 3, in an embodiment, an outer layer of the support 100 is provided as an insulating layer 110. That is, the portion of the drying rack exposed to the outside, which is electrically conductive, is only disposed on the airing rod 300, and the insulating layer 110 can prevent the bracket 100 from being short-circuited due to the erroneous contact with water or the wet cloth 500, which may cause damage to the drying rack. The above two schemes may be set in one embodiment at the same time, or may be set in the corresponding embodiment separately.

In an embodiment, referring to fig. 1 and 3, the airing bars 300 are provided with clamping members (not shown) electrically connected to the corresponding airing bars 300, wherein the clamping members are used for clamping the ends of the cloth items 500 and form a drying circuit with the airing bars 300 of opposite electrodes. It will be understood that the clamping members are correspondingly disposed on the positive electrode rod 310 and the negative electrode rod 320, and the clamping members and the corresponding positive electrode rod 310 or negative electrode rod 320 have the same electrode, that is, the clamping members are also respectively disposed as a positive electrode clamping member and a negative electrode clamping member, the positive electrode clamping member is correspondingly electrically connected to the positive electrode rod 310, the negative electrode clamping member is correspondingly electrically connected to the negative electrode rod 320, if multiple sets of electrolytic rod sets are provided, the multiple positive electrode clamping members are disposed in parallel, and the multiple negative electrode clamping members are also disposed in parallel. Thus, when the number of poles 300 contacted by the cloth items 500 is an odd number, the clamps on the adjacent poles 300 may clamp the ends of the cloth items 500 such that the number of poles 300 to which the cloth items 500 are electrically connected is an even number, such as: when the cloth 500 contacts with 4 positive poles 310 and 5 negative poles 320, four drying loops are formed in the cloth 500, and in this case, one negative pole 320 does not have a matched airing pole 300 or one negative pole 320 cannot electrolyze water suspended on the cloth 500 outside the negative pole 320, at this time, the end of the cloth 500 is clamped by the clamp on the positive pole 310 adjacent to the negative pole 320 and not contacting with the cloth 500, so that drying loops are formed among the negative pole 320, the clamp, the corresponding positive pole 310 and the end of the cloth 500, thereby guaranteeing that water at all positions on the cloth 500 can be electrolyzed, improving the drying area on the cloth 500, and improving the drying effect.

In an embodiment, referring to fig. 2, the drying rack is further provided with a safety resistor 400, and the safety resistor 400 is connected in series with the drying circuit. It will be appreciated that the safety resistor 400 has the effect of protecting the drying circuit from excessive current in the drying circuit causing the electrical control 200 to burn out and also from excessive current damaging the cloth 500. Specifically, when the drying rack is provided with a plurality of groups of electrolysis rod groups, any positive electrode rod 310 or negative electrode rod 320 is correspondingly provided with a safety resistor 400 on a circuit connected with the power control 200, and when the cloth 500 is placed on the drying rack, the cloth is protected by the safety resistor 400 in a plurality of drying loops formed.
