Fig. 1 shows a structural diagram of a central air-conditioning outlet air purification system according to an embodiment of the present application. As shown in fig. 1, the system includes: a fan coil 110 and a scrubber 120. The fan coil 110 is used as a wind supply pipeline of the central air conditioner, is suitable for being installed in a suspended ceiling layer 200 of an indoor roof, and is used for supplying air subjected to temperature adjustment by the central air conditioner host machine to the indoor space so as to achieve the purpose of adjusting the room temperature. Here, it is to be noted that the fan coil 110 has a return air inlet 111 for intake air and a supply air outlet (not shown in the figure) for outlet air.

The purifier 120 includes a housing 121 and a purifying assembly 123. Referring to fig. 2, the housing 121 is a hollow structure and has two openings opposite to each other. That is to say, in this application, the opening has all been seted up to two relative terminal surfaces that set up of casing 121 to make hollow structure's casing 121 whole be one front and back do not have the bottom surface ghost. The housing 121 can be inserted into the air outlet of the fan coil 110 and is fixedly connected to the side wall of the air outlet. It should be noted that one end of the casing 121 adjacent to the air supply opening is an air inlet port, and the other end opposite to the air inlet port is an air outlet port.

The power input line of the power module 122 is electrically connected to a power supply (i.e., an indoor distribution box) after passing through the through hole and the threading hole in sequence.

That is to say, the central air-conditioning air-out purification system of the present application, through configuring a power module 122 to the purification component 123 separately in the casing 121, supplies power to the purification component 123 by the power module 122 separately, and compared with the mode that the central air-conditioning in the related art shares the same power module 122, the power connection is more flexible, and meanwhile, the replacement and maintenance of the power module 122 are also facilitated. And moreover, the independent work of the room temperature adjusting module and the air purifying module in the central air conditioner is realized, so that the room temperature adjusting module and the air purifying module are not influenced by each other.

Further, the power module 122 includes a power box and a power supply circuit. Referring to fig. 2 and 3, the shape of the power box may be configured to be a structure matching the shape of the cavity of the housing 121, so that when the purifier 120 is installed, the power box may be directly pushed into the housing 121, which effectively simplifies the installation manner of the power box and reduces the installation difficulty of the purifier 120. Meanwhile, the detachable connection of the power module 122 on the housing 121 may be achieved by providing a power box detachably connected to a sidewall of the housing 121.

That is, in one possible implementation, the power supply box has a box opening that is disposed toward a side wall of the housing 121. The circuit of the power supply circuit is directly connected to the power supply through the box opening and the through hole and the threading hole.

It should be noted that the power supply circuit may be implemented by a conventional power supply circuit in the art, and details are not described here.

Referring to fig. 4 to 6, when the air is purified by the purifier 120 in the central air-conditioning outlet air purification system according to the embodiment of the present invention, the air is mainly purified based on the principle of Intense Field Dielectric (IFD) technology. That is, the air is ionized to charge the dust particles in the air, and a strong electric field is generated using a dielectric medium as a carrier to attract the charged fine particles moving in the air, thereby adsorbing the moving fine particles in the air.

Based on the above purification principle, the purification assembly 123 of the present application correspondingly includes a filtering module 1230, a charging module 1231, and a dust collecting module 1232. The filtering module 1230, the charging module 1231 and the dust collecting module 1232 are all frame-shaped structures. In addition, the filtering module 1230, the charging module 1231, and the dust collecting module 1232 are sequentially disposed layer by layer along the extending direction from the air outlet to the air inlet. That is, the filtering module 1230 is disposed at the air inlet port, the charging module 1231 is disposed at the middle position of the housing 121, and the dust collecting module 1232 is disposed at the air outlet port.

The mesh size of the filter mesh 1230a may be flexibly set according to actual conditions, and is not particularly limited herein. Moreover, the filtering module 1230 can be implemented by a filtering net 1230a which is conventional in the art, and therefore, the description thereof is omitted here.

Referring to fig. 5, in the present application, the charging module 1231 includes a fixing frame 1231a and a connecting rod (not shown). Wherein, the shape of the fixing frame 1231a matches with the shape of the cavity of the housing 121, and the fixing frame 1231a is installed on the sidewall of the housing 121; the number of the connecting rods is multiple, and the connecting rods are sequentially arranged and fixed in the fixing frame 1231 a; each connecting rod is provided with a discharge electrode 1231b, the discharge electrode 1231b is in a pole needle structure, and the discharge electrode 1231b points to the filtering module 1230.

It should be noted that the output line of the power supply circuit may be electrically connected to the discharge electrode 1231b along the sidewall of the fixed frame 1231a and the rod wall of the connecting rod, and the point discharge is performed through the discharge electrode 1231 b. That is, as shown in fig. 5, the side wall of the fixed frame 1231a may be provided with an electrical connection contact 1231c, and the output line of the power module 122 may be electrically connected to the electrical connection contact 1231 c.

Here, it should be noted that there may be a plurality of discharge electrodes 1231b attached to the connection rod, or one discharge electrode. In the present application, only one discharge electrode 1231b needs to be mounted on the connection rod. Also, the mounting positions of the discharge electrodes 1231b on the connection bars may be the same. Such as: the discharge electrodes 1231b are all installed at the middle positions of the corresponding connection rods.

The part where the discharge electrode 1231b is installed may also be provided as a connection window (as shown in fig. 5). A discharge electrode 1231b is installed at a window frame of the connection window. Alternatively, the discharge electrode 1231b may be mounted in other manners, which are not described herein.

In addition, to simplify the installation of the purification assembly 123 on the housing 121, in one possible implementation, the filtering module 1230 and the charging module 1231 may be configured to share a frame. That is, the filter mesh 1230a is installed inside the fixed frame 1231a, and covers the frame body of the fixed frame 1231 a. And, there is a preset distance between the filter mesh 1230a and the connection rod. That is, the filter mesh 1230a is disposed in parallel with the connection rod.

Further, referring to fig. 6, the dust collecting module 1232 includes a dust collecting frame 1232a and a dust collecting net 1232 b. Wherein the dust collection frame 1232a has a shape matching the shape of the cavity of the housing 121. The dust collection frame 1232a is engaged with the sidewall of the housing 121. The dust collection net 1232b is installed in the dust collection frame 1232a and detachably connected to the dust collection frame 1232 a. Wherein, the dust collecting net 1232b is a honeycomb hollow passage structure, and the dielectric carrier is provided on the dust collecting net 1232 b. The output line of the power supply circuit is electrically connected to the dust collecting net 1232b along the side wall of the dust collecting frame 1232 a.

As shown in fig. 6, the electrical connection between the dust collection module 1232 and the power supply module 122 can be achieved by providing electrical connection contacts on the sidewall of the dust collection frame 1232 a.

The dust collecting net 1232b is arranged into a honeycomb hollow channel structure, so that a voltage applied to the dust collecting net 1232b can generate a strong electric field by using a dielectric medium on the dust collecting net 1232b as a carrier, and generate a huge attraction force on particles moving in the air, thereby achieving the purpose of adsorbing nearly 100% of moving particles in the air. Meanwhile, the microorganism such as bacteria attached to the particles can be synchronously collected and killed in a strong electric field, so that the aim of purification and sterilization is fulfilled.

The dust collection frame 1232a can be locked to the housing 121 by providing a stopper 1210 and a support 1211 on a sidewall of the housing 121. That is, referring to fig. 3, a limiting member 1210 and a supporting member 1211 are disposed on a side wall of the housing 121. The position-limiting member 1210 is disposed adjacent to the air outlet port compared to the support 1211. In an implementation manner, the main body of the limiting member 1210 is a bent plate-shaped structure, and one plate surface of the limiting member 1210 is attached and fixedly connected to the inner wall of the housing 121.

The main body of the support 1211 is a block structure, and the support 1211 is detachably connected to the sidewall of the housing 121. A gap is formed between the limiting member 1210 and the support member 1211, and the sidewall of the dust collection frame 1232a is disposed in the gap, so that the dust collection frame 1232a is fixed in the housing 121 by the blocking and supporting of the limiting member 1210 and the support member 1211. Meanwhile, by setting the gap between the limiting member 1210 and the support 1211, the installation angle of the dust collecting frame 1232a in the housing 121 can be kept unchanged, so as to ensure that the integrated frame can be kept in the same state (e.g., vertical state) in the housing 121 at any time, thereby achieving the maximum area of adsorption and achieving the sufficient adsorption of ionized particles.

Further, the number of the position-limiting members 1210 may be plural. The plurality of stoppers 1210 are sequentially arranged in an up-down structure. Wherein, the interval between two adjacent limiting members 1210 is equal. By providing the plurality of stoppers 1210, the fixing and limiting effects on the dust collection frame 1232a can be effectively increased, so that the dust collection frame 1232a can be more stably fixed.

For example, the number of the stoppers 1210 may be two, and the upper and lower stoppers 1210 respectively fix and support the upper and lower portions of the dust collection frame 1232a, thereby more effectively ensuring that the installation angle of the dust collection frame 1232a in the housing 121 can be kept unchanged. Meanwhile, it is preferable that the length of the support 1211 is greater than the spaced distance between the stoppers 1210.

In addition, in this application, a sealing layer is coated between the casing 121 and the side wall of the air blowing opening, so as to avoid the situation that the gap exists between the casing 121 and the air blowing opening, which causes the unpurified air to be blown into the room through the gap.

Simultaneously, can also set up the flame retardant coating at the lateral wall of supply-air outlet to avoid causing the phenomenon of conflagration when leading to the electric leakage because reasons such as circuit ageing, this has just so further improved the security of the central air conditioning air-out clean system of this application. Wherein, it should be pointed out that, the material of flame retardant coating is fire prevention fire retardant material.

It should be noted that, although the central air conditioning outlet air purification system of the present application is described by taking fig. 1 to fig. 6 as an example, those skilled in the art can understand that the present application should not be limited thereto. In fact, the user can flexibly set the structures of all parts according to personal preference and/or practical application scenes as long as the air blown out from the air supply outlet of the central air conditioner can be purified.
