Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning equipment, and in particular relates to a combined air-conditioning unit. Background Art

[0002] Combined air conditioners are generally composed of more than three functional sections, such as: primary and new return air section, heating section, filtration section and heat recovery section, etc. Different air treatment requirements can be achieved through the combination of different functional sections. In the filtration section, it is usually necessary to install a purification device to achieve the purification effect.

[0003] The purification principle of electronic purifiers is to generate positive corona discharge to charge the particles in the air, and then adsorb them on the surface of the adsorbent with opposite electrodes. The existing electronic purifiers have a low dust holding capacity. When the charge on the surface of the adsorbent is covered with a lot of dust, the adsorption capacity of the adsorbent is reduced, and the dust is transported backwards with the airflow, resulting in low purification efficiency.

[0004] In addition, when the electronic purifier is transported as a whole, because it contains electronic components, shock absorption protection is required to avoid damage to the components. Therefore, high packaging requirements are required, resulting in relatively high transportation and maintenance costs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0060] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0061] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0062] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0063] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0064] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0065] The present application proposes a combined air conditioning unit, which includes an outer shell and a purification device. The outer shell is formed with an air inlet for introducing external airflow and an air outlet for outputting the airflow to the room.

[0066] An air inlet channel is formed between the air inlet and the air outlet, and the purification device is arranged in the air inlet channel.

[0067] The purification device is used to filter the airflow in the air inlet channel and filter out impurities such as dust therein.

[0068] The purification device involved in the present application is an electronic purifier.

[0069] Electronic purifiers generate positive corona discharge to make the particles in the air positively charged, and then use electrostatic force to adsorb the charged particles (dust) onto the dust collection device.

[0070] In addition, after the microbial aerosol is adsorbed, its cell membrane is broken down and destroyed by the high-voltage electric field, and the protein in the cell is denatured or separated, thus playing a bactericidal role.

[0071] Specifically, refer to Figure 1-Figure 5 The purification device involved in the present application includes at least one purification unit 200.

[0072] The purification unit 200 includes a purification outer frame 240 , a filter element 230 and an electric control box 210 .

[0073] The purification outer frame 240 is a frame structure, and the end surface of the purification outer frame 240 is arranged along a direction perpendicular to the flow direction of the airflow.

[0074] One end of the purification outer frame 240 located on the windward side is an input end, and one end on the leeward side is an output end. A first charging part 241 is provided at the input end of the purification outer frame 240 .

[0075] The filter element 230 is connected to the purification outer frame 240. Specifically, in order to improve the filtering effect, the filter element 230 includes a plurality of filtering channels, and each filtering channel gradually contracts along the flow direction of the airflow.

[0076] That is, the inlet size of the filtration channel is larger than the outlet size.

[0077] In some embodiments, in combination Fig.10 The cross-sectional shape of each filter channel is triangular, and the two side walls of the filter channel are butted against each other at the output end so that the airflow can be completely filtered through the filter element 230 .

[0078] The filter element 230 specifically includes a filter screen 231 and a support frame. The cross-sectional shape of the filter screen 231 along the horizontal direction is a broken line shape. The filter screen 231 forms a plurality of filter channels under the action of the support frame.

[0079] In some embodiments of the present application, reference Figure 6 The output end of the purification outer frame 240 is provided with a horizontal upper support portion 245 and a lower support portion 244, and the upper support portion 245 and the lower support portion 244 are both support plates.

[0080] The upper and lower ends of the filter element 230 are connected to the upper support portion 245 and the lower support portion 244 respectively.

[0081] A plurality of supporting longitudinal beams are further provided between the upper supporting portion 245 and the lower supporting portion 244 , and the filter element 230 is fixed between the upper supporting portion 245 and the lower supporting portion 244 via the supporting longitudinal beams.

[0082] Specifically, combined again Fig.10 The supporting longitudinal beam is divided into a front supporting longitudinal beam 2321 arranged upstream of the airflow and a rear supporting longitudinal beam 2322 arranged downstream of the airflow along the flow direction of the airflow.

[0083] There are multiple front supporting longitudinal beams 2321 and multiple rear supporting longitudinal beams 2322 , and the multiple front supporting longitudinal beams 2321 are arranged at intervals, and the entrance of the filtering channel is formed between adjacent front supporting longitudinal beams 2321 .

[0084] The rear supporting longitudinal beam 2322 and the front supporting longitudinal beam 2321 are arranged alternately, that is, the rear supporting longitudinal beam 2322 is arranged between two adjacent front supporting longitudinal beams 2321, and the rear supporting longitudinal beam 2322 is located at the output end position of the corresponding filtering channel.

[0085] The filter screen 231 forms a filter channel through the front supporting longitudinal beam 2321 and the corresponding rear supporting longitudinal beam 2322 .

[0086] A second charged portion 232 is formed on the side wall of each filter channel, and the electrodes of the second charged portion 232 and the first charged portion 241 are opposite.

[0087] In one embodiment, the first charging portion 241 is a plurality of metal wires spaced apart on the purification outer frame 240 .

[0088] The metal wires are arranged parallel to each other, and the metal wires are arranged along a horizontal or vertical direction at the input end of the purification outer frame 240 .

[0089] The second charged portion 232 is a metal sheet attached to the filter screen 231 on both sides of the filter channel.

[0090] The first charging portion 241 is negatively charged, and the second charging portion 232 is positively charged.

[0091] Alternatively, the second charging portion 232 is charged with positive charge, and the second charging portion 233 is charged with negative charge of the opposite polarity.

[0092] Taking the example that the first charged part 241 is negatively charged and the second charged part 232 is positively charged, the dust in the air is negatively charged after passing through the first charged part 241 , and then input into the filter channel and adsorbed by the second charged part 232 .

[0093] The second charged part 232 of the metal sheet structure has a larger dust holding capacity, absorbs more charged dust, and has a better purification effect.

[0094] The purification device charges the dust and other impurities in the airflow through the first charged part 241, and the charged dust and other impurities are adsorbed on the second charged part 232 under the action of electrostatic force; the second charged part 232 is attached to the side wall of the filter channel, and the second charged part 232 has a large adsorption area, which can increase the dust holding capacity, increase the adsorption effect of the purification device, and is beneficial to extend the maintenance period of the purification device and reduce maintenance costs.

[0095] The output end of the filtration channel is blocked by the filter 231. Therefore, when a large amount of charged dust is adsorbed on the second charged part 232, the adsorption effect is reduced, and the dust clumps gathered on the second charged part 232 may fall off the second charged part 232. The dust clumps that fall off can be intercepted by the filter 231 at the output end, thereby preventing the dust from continuing to be transported downstream after falling off.

[0096] The first electrified part 241 and the second electrified part 232 are powered by the electric control box 210 . The electric control box 210 is connected to the outside of the purification outer frame 240 . The electric control box 210 is externally connected to a power supply line.

[0097] In some embodiments of the present application, reference Figure 3 The purification device includes a plurality of purification units 200, and the purification units 200 are arranged in an array.

[0098] refer to Figure 7 The purification device further includes a support frame 220 , and adjacent purification units 200 are detachably connected via the support frame 220 .

[0099] The purification outer frame 240 is detachably connected to the support frame 220 , and the electric control box 210 is fixed above the support frame 220 .

[0100] The support frame 220 is a frame structure, and a limiting inner edge 221 extending inward is formed on the inner side of the support frame 220 . An installation position is formed between the limiting inner edges 221 . The size of the purification outer frame 240 is larger than the size of the installation position, and the limiting inner edge 221 serves to limit the purification outer frame 240 .

[0101] During installation, the filter element 230 is installed from the front side to the rear side of the support frame 220 until the purification outer frame 240 on the filter element 230 is in contact with the limiting inner edge 221 , and then the purification outer frame 240 is fixed to the support frame 220 .

[0102] In some embodiments of the present application, fixing holes 223 are further formed on the peripheral side of the support frame 220 , and the support frames 220 between adjacent purification units 200 are connected and fixed through the fixing holes 223 .

[0103] The purification device is formed by assembling the purification units 200. The structures such as the electric control box 210, the purification outer frame 240 and the filter element 230 in each purification unit 200 can be processed separately and finally assembled, which is conducive to improving production efficiency.

[0104] In addition, the electric control box 210 in the purification device can be fixed on the purification frame 240 by later assembly. Therefore, during transportation, only the electric control box 210 with higher transportation requirements needs to be packaged, which simplifies the packaging and transportation of structures such as the filter element 230 and the purification frame 240 in the purification device, and reduces the packaging and transportation costs.

[0105] Combination Figure 3 , Fig.13 In order to reduce the airflow passing through the gap between the purification device and the air inlet channel, a wind shield 100 is further provided between the purification device and the air inlet channel.

[0106] The wind shield 100 is arranged between the purification device and the air inlet passage.

[0107] The windshield member 100 at least includes a windshield bottom plate 110 disposed at the bottom of the purification device and windshield side plates 120 disposed at both sides of the purification device.

[0108] Alternatively, the wind shield 100 further includes a wind shield top plate arranged on the top of the purification device.

[0109] Each windshield member 100 , such as the windshield bottom plate 110 , the windshield side plate 120 and the windshield top plate, comprises a windshield surface 101 and a connecting inner edge 102 and a connecting outer edge 103 formed on both sides of the windshield surface 101 .

[0110] The connecting inner edge 102 and the connecting outer edge 103 are both perpendicular to the wind shielding surface 101 , the connecting inner edge 102 is connected to the supporting frame 220 of the adjacent purification unit 200 , and the connecting outer edge 103 is connected to the air inlet channel.

[0111] The wind shield 100 further blocks the gap between the purification device and the air inlet channel, thereby improving the filtering effect of the airflow.

[0112] refer to Figure 7 , Figure 8 as well as Fig.11 The electric control box 210 specifically includes a first power supply unit 212 and a second power supply unit 213 . The first power supply unit 212 is connected to the first live unit 241 , and the second power supply unit 213 is connected to the second live unit 232 .

[0113] The bottom of the electric control box 210 is respectively formed with power supply electrode sheets connected to the first power supply part 212 and the second power supply part 213 . Specifically, the power supply electrode sheets include a first power supply electrode sheet 214 connected to the first power supply part 212 and a second power supply electrode sheet 215 connected to the second power supply part 213 .

[0114] A charged electrode sheet connected to the first charged part 241 and the second charged part 232 is formed on the top of the purification outer frame 240 , and the charged electrode sheet includes a first charged electrode sheet 242 connected to the first charged part and a second charged electrode sheet 243 connected to the second charged part.

[0115] A avoidance hole 222 is formed on the top of the support frame 220 , and the power supply electrode sheet passes through the avoidance hole 222 to be connected with the corresponding power receiving electrode sheet.

[0116] There are two avoidance holes 222 . In the installed state, the first power supply electrode sheet 214 is connected to the first power receiving electrode sheet 242 through the avoidance hole 222 , and the second power supply electrode sheet 215 is connected to the second power receiving electrode sheet 243 through the avoidance hole 222 for power supply.

[0117] A signal unit 211 is formed on the electric control box 210 for displaying the working status of the corresponding purification unit 200. When the purification unit 200 is powered abnormally, the signal unit 211 sends an alarm signal, which is displayed through a display panel or other display component provided on the outer shell for user observation.

[0118] The power transmission of the power supply unit, the live unit, etc., and the acquisition and transmission of related signals in the signal unit 211 are all existing technologies and will not be explained in detail here.

[0119] In some embodiments of the present application, in order to facilitate monitoring of the blocking state of the purification device, wind pressure detection components are respectively provided at the input end and the output end of the purification device to detect the wind pressure difference before and after the purification device.

[0120] When the wind pressure difference between the two wind pressure detection elements is greater than the preset wind pressure difference, it indicates that the filter element 230 of the purification device is seriously blocked and needs to be cleaned or replaced in time.

[0121] On the other hand, the present application also proposes a combined air conditioning unit, which includes an outer shell and a purification device, wherein the outer shell is formed with an air inlet for introducing external airflow and an air outlet for outputting the airflow to the room.

[0122] An air inlet channel is formed between the air inlet and the air outlet, and the purification device is arranged in the air inlet channel.

[0123] The purification device is used to filter the airflow in the air inlet channel and filter out impurities such as dust therein.

[0124] The purification device includes at least one purification unit 200, and the purification unit 200 includes a first charged part 241, a second charged part 232 and a filter 230 which are sequentially arranged on a purification outer frame 240 along the flow direction of the airflow;

[0125] The purification unit 200 is configured as follows: the airflow flows through the first charged part 241 to charge the dust in the airflow, and when the charged dust passes through the second charged part 232, it adheres to the surface of the second charged part 232, and the purified airflow is output from the filter element 230 to achieve the purpose of purification.

[0126] The specific installation of the first charged part 241, the second charged part 232 and the filter 230 on the purification outer frame 240 can be achieved in the following ways:

[0127] Method 1:

[0128] refer to Fig.14 The input end of the purification outer frame 240 is an open structure facing the windward side, and the filter element 230 is arranged at the output end of the purification outer frame 240. The filter element 230 is a filter net 231 structure.

[0129] The first charging part 241 is specifically a plurality of metal wires arranged at intervals in the horizontal direction or the vertical direction at the input end of the purification outer frame 240 .

[0130] The second charging part 232 is a plurality of metal sheets vertically arranged in the purification outer frame 240 , and the metal sheets are distributed at an angle.

[0131] The first charging portion 241 is negatively charged, and the second charging portion 232 is positively charged.

[0132] When the airflow passes through the purification device, it first passes through the first charged part 241. The charged impurities such as dust are adsorbed on the second charged part 232 under the action of electrostatic force. Then, the airflow passes through the filter element 230 and is transported downstream.

[0133] When there is a large amount of charged dust adsorbed on the second charged part 232, its adsorption effect is reduced, and the dust clumps gathered on the second charged part 232 may fall off the second charged part 232. The fallen dust clumps can be intercepted by the filter element 230 at the output end to prevent the dust from continuing to be transported downstream after falling off.
