Description

Technical Field

[0001] This utility model relates to the field of indoor unit technology for air conditioning units, specifically to an indoor unit for an all-air air conditioning unit. Background Technology

[0002] All-air conditioning units are widely used in public buildings such as hotels, airports, and convention centers, which are densely populated places. They feature fast air circulation and high efficiency in delivering cool and hot air. During operation, all-air conditioning units mainly rely on internally installed filter components to achieve air filtration and purification. However, the filter components in existing all-air conditioning units are generally nested. In actual operation, because the filters are relatively long, if the gap between the nesting joints is small, it will lead to significant friction between the filter and the joints. This can damage the filter and make it difficult to disassemble and reassemble. If the gap between the nesting joints is large, it will affect the sealing of the nested installation, thus affecting the filtration effect. Utility Model Content

[0003] The purpose of this utility model is to provide an indoor unit for an all-air conditioning unit to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an indoor unit of an all-air conditioning unit, including a housing, an electrical box fixed to the front end of the housing, a fixing component detachably installed on the housing, a filter component for gas filtration and purification installed on the fixing component, a partition inside the housing disposed on the left side of the fixing component, a fan installed on the partition, a water coil finned heat exchanger inside the housing disposed on the left side of the partition, and a steam spray pipe inside the housing disposed on the left side of the water coil finned heat exchanger.

[0005] Preferably, an air inlet and an air return outlet are installed on the right side of the housing, and two air outlets are installed on the left side of the housing. A first temperature and humidity sensor is fixed inside the housing on the side of the air inlet, and a second temperature and humidity sensor is fixed inside the housing on the side of the air outlet. With the above structure, normal air flow can be ensured inside the housing, and the temperature and humidity of the air entering and leaving the housing can be detected, so as to achieve temperature and humidity control.

[0006] Preferably, a PM2.5 sensor is also fixed inside the housing, and the PM2.5 sensor is located between the partition and the water coil finned heat exchanger. With the above structure, PM2.5 in the filtered air can be detected so as to determine the service life of the filter.

[0007] Preferably, the fixing component includes a mounting bracket that is slidably connected to the housing, and the mounting bracket is slidably connected to the limiting plate. The limiting plate is symmetrically distributed about the center line of the mounting bracket and is fixed inside the housing. Through the above structure, the mounting bracket can be guided and limited during installation, ensuring the normal operation of the device.

[0008] Preferably, the mounting bracket is also symmetrically fixed with front and rear fixing plates, and a sliding rod is slidably connected to the fixing plate. The upper end of the sliding rod contacts the pressure plate, and the pressure plate and the fixing plate are locked together by bolts. The locking between the pressure plate and the fixing plate can provide a basic force for the movement of the sliding rod.

[0009] Preferably, a spring is fixed between the slide rod and the fixed plate, and one end of the slide rod is rotatably connected to the connecting rod, and the other end of the connecting rod is rotatably connected to the slider. Through the elastic action of the spring, a basic force can be provided for the automatic reset of the slide rod, and in conjunction with the transmission action of the connecting rod, a basic force can be provided for the movement of the slider.

[0010] Preferably, the slider and the fixed plate are slidably connected, and the slider is fixed on the clamping plate. A sealing gasket is also fixed on the clamping plate.

[0011] Preferably, the filtration assembly consists of a coarse filter, a molecular sieve filter, and a high-efficiency filter, and the coarse filter, molecular sieve filter, and high-efficiency filter are installed from right to left. Through the above structure, multi-layer filtration and purification of air can be achieved, ensuring the air purification effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the indoor unit of the all-air air conditioning unit adopts an elastic adjustable clamping and limiting mechanism, which can not only realize the positioning and fixing of the filter components, but also increase the distance between the clamps when the filter components are disassembled and installed, thus making the disassembly and installation of the filter components more convenient.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 This utility model provides a technical solution: an indoor unit of an all-air conditioning unit, including a housing 1, an electrical box 2 fixed to the front end of the housing 1, a fixing component 4 detachably installed on the housing 1, a filter component 5 for gas filtration and purification installed on the fixing component 4, a partition 6 fixed inside the housing 1 on the left side of the fixing component 4, a fan 7 installed on the partition 6, a water coil finned heat exchanger 8 fixed inside the housing 1 on the left side of the partition 6, and a steam spray pipe 9 fixed inside the housing 1 on the left side of the water coil finned heat exchanger 8.

[0022] An air inlet 101 and a return air inlet 102 are installed on the right side of the housing 1, and two air outlets 103 are installed on the left side of the housing 1. A first temperature and humidity sensor 104 is fixed inside the housing 1 on the side of the air inlet 101, and a second temperature and humidity sensor 105 is fixed inside the housing 1 on the side of the air outlet 103. A PM2.5 sensor 106 is also fixed inside the housing 1 and is located between the partition 6 and the water coil finned heat exchanger 8. The filter assembly 5 consists of a coarse filter 501, a molecular sieve filter 502, and a high-efficiency filter 503, and the coarse filter 501, the molecular sieve filter 502, and the high-efficiency filter 503 are distributed and installed from right to left.

[0023] When using the indoor unit of this all-air conditioning unit, the following operating modes are available:

[0024] Ventilation mode: The fan 7 can draw outdoor fresh air and indoor return air into the housing 1 through the air inlet 101 and return air outlet 102 respectively. The outdoor fresh air and indoor return air are mixed in the housing 1, and then filtered and purified by the coarse filter 501, molecular sieve filter 502 and high efficiency filter 503 before being sent into the room through the air outlet 103.

[0025] Cooling and heating mode: Outdoor fresh air and indoor return air are drawn into the housing 1 through the air inlet 101 and return air outlet 102 respectively by the fan 7. The outdoor fresh air and indoor return air are mixed in the housing 1. The temperature of the air entering the housing 1 can be monitored by the first temperature and humidity sensor 104. When cooling or heating is required, the air is filtered and purified by the coarse filter 501, molecular sieve filter 502 and high efficiency filter 503 and then comes into contact with the water coil finned heat exchanger 8. The air can be cooled or heated by the refrigerant or heat transfer medium in the water coil finned heat exchanger 8, thereby achieving temperature control. The temperature of the air after cooling or heating can be monitored by the second temperature and humidity sensor 105 to ensure that the temperature meets the requirements. Finally, the air is sent into the room through the air outlet 103.

[0026] Dehumidification mode: Outdoor fresh air and indoor return air can be drawn into the housing 1 through the air inlet 101 and return air outlet 102 respectively by the fan 7. The outdoor fresh air and indoor return air are mixed in the housing 1. The humidity of the air entering the housing 1 can be monitored by the first temperature and humidity sensor 104. When dehumidification is required, the air is filtered and purified by the coarse filter 501, molecular sieve filter 502 and high efficiency filter 503. After being cooled and dehumidified by the cold medium introduced into the water coil fin heat exchanger 8, it is heated by TPC electric heating (not shown in the figure) and then sent to the room through the air outlet 103.

[0027] Humidification mode: Only activated in ventilation or heating mode. Outdoor fresh air and indoor return air are drawn into the housing 1 through the air inlet 101 and return air outlet 102 respectively by the fan 7. Outdoor fresh air and indoor return air are mixed in the housing 1. The temperature of the air entering the housing 1 can be monitored by the first temperature and humidity sensor 104. When humidification is required, the air is filtered and purified by the coarse filter 501, molecular sieve filter 502 and high efficiency filter 503 and then comes into contact with the water coil finned heat exchanger 8. The air is heated by the heat medium introduced into the water coil finned heat exchanger 8. Then, the steam is sent into the housing 1 through the steam spray pipe 9 by the matching electrode humidification module to humidify the air. Finally, it is sent into the room through the air outlet 103.

[0028] The fixing component 4 includes a mounting bracket 401 that is slidably connected to the housing 1, and a limiting plate 3 that is also slidably connected to the mounting bracket 401. The limiting plate 3 is symmetrically distributed about the center line of the mounting bracket 401 and is fixed inside the housing 1. A fixing plate 402 is also symmetrically fixed to the mounting bracket 401, and a sliding rod 403 is slidably connected to the fixing plate 402. The upper end of the sliding rod 403 contacts the pressure plate 409, and the pressure plate 409 is locked to the fixing plate 402 by bolts. A spring 404 is fixed between the sliding rod 403 and the fixing plate 402, and one end of the sliding rod 403 is rotatably connected to the connecting rod 405. The other end of the connecting rod 405 is rotatably connected to the slider 406. The slider 406 is slidably connected to the fixing plate 402 and is fixed to the clamping plate 407. A sealing gasket 408 is also fixed to the clamping plate 407, and the sealing gasket 408 contacts the filter component 5 to achieve a limiting function.

[0029] During prolonged use, the PM2.5 sensor 106 can monitor the purified air. If the PM2.5 sensor 106 continuously reports a PM2.5 content greater than 50 for 3 consecutive days, it indicates that the filter assembly 5 needs to be replaced. At this time, simply release the lock between the mounting bracket 401 and the housing 1, remove the mounting bracket 401, and then release the bolt lock between the pressure plate 409 and the fixing plate 402. At this time, the pressure plate 409 releases its limiting effect on the slide rod 403. Under the action of the spring 404, the slide rod 403 moves upward. With the transmission action of the connecting rod 405, the slider 406 is forced to slide, thereby moving the clamping plate 407 and the sealing gasket 408, increasing the distance between the two sealing gaskets 408. The pressure plate 409 releases the limiting seal on the filter assembly 5, facilitating its disassembly and replacement. After the new filter assembly 5 is installed, the pressure plate 409 contacts and presses down on the slide rod 403, causing the slide rod 403 to move downward under force. At this time, the spring 404 contracts under force. According to the above principle, the distance between the two sealing gaskets 408 can be reduced. When the pressure plate 409 contacts the fixing plate 402, the sealing gaskets 408 are in contact with the filter assembly 5, achieving the clamping and sealing effect of the filter assembly 5 and ensuring the stability of the filter assembly 5 installation. Then, the pressure plate 409 and the fixing plate 402 are locked with bolts. Finally, the mounting bracket 401 can be installed through the sliding guide between the mounting bracket 401 and the limiting plate 3, thereby realizing the replacement of the filter assembly 5.
