[0002] In order to solve the contradiction between the indoor air quality and energy consumption in modern buildings, during the process of exchanging outdoor air with indoor air, the fresh air energy-saving air conditioning device recovers and utilizes the heat of the indoor air during the heating and cooling processes of the outdoor air, and then pre-treats the fresh outdoor air, thereby improving the energy utilization efficiency and reducing the operating cost of the air conditioning system.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figures 1 to 10 , a fresh air energy-saving air conditioner device according to a preferred embodiment of the present invention will be described in detail below. A fresh air energy-saving air conditioner device includes an outer frame 1. Inside the outer frame 1, there is a switching mechanism 2 to ensure that the filter inside the device is always in a clean state. Inside the outer frame 1, there is a cleaning mechanism 3 to clean the impurities on the surface of the filter. Inside the outer frame 1, there is a loosening mechanism 4 to facilitate the disassembly of the filter inside the device. The switching mechanism 2 includes a shielding plate 212 for blocking the filter. The cleaning mechanism 3 includes a storage box 3117 for collecting the impurities on the surface of the filter. The loosening mechanism 4 includes a swinging rod 416 for loosening the impurities on the surface of the filter.

[0035] Inside the outer frame 1, a fresh air groove and a transfer groove are opened. At both ends of the fresh air groove of the outer frame 1, a fresh air inlet 101 and a fresh air outlet 104 are fixedly connected. At both ends of the transmission groove of the outer frame 1, an old air outlet 102 and an old air inlet 103 are fixedly connected. Between the fresh air groove and the transfer groove of the outer frame 1, there are a heat exchange chamber 105 and a dehumidification and disinfection chamber 106.

It is dehumidified and disinfected through the dehumidification and disinfection chamber 106 and enters the room through the fresh air outlet 104 to achieve the circulation of fresh air and old air.

[0036] As Figure 3Among them, the switching mechanism 2 includes two filter sieve plates 211. The inner wall surface of the fresh air groove of the outer frame 1 is fixedly connected with two filter screen sliding frames. Both filter sieve plates 211 are slidably connected inside the filter screen sliding frames on the inner wall of the outer frame 1. The baffle plate 212 is slidably connected inside the fresh air groove. The baffle plate 212 is in contact with the surface of the filter sieve plate 211. A wind sensor is arranged between the filter sieve plate 211 and the heat exchange chamber 105. The surface of the baffle plate 212 is fixedly connected with an electric telescopic rod. When the wind force passing through the filter sieve plate 211 drops to a certain threshold, the electric telescopic rod pushes the baffle plate 212 to slide leftward to close the blocked filter sieve plate 211, and then subsequent cleaning or disassembly is carried out. At the same time, the filter sieve plate 211 in a smooth state is exposed outside, so that the device can still operate normally during the cleaning of the filter screen. Even during the cleaning of the filter sieve plate 211, users can still enjoy continuous ventilation and air purification without stopping the air conditioning system, ensuring the continuity of indoor air quality.

[0037] As Figure 5 Among them, the cleaning mechanism 3 includes a power push rod 311. The power push rod 311 is slidably connected inside the outer frame 1.

A limit clamping shaft 314 is fixedly connected to the surface of the sliding push rod 312. A first spring 313 is fixedly connected between the limit clamping shaft 314 and the power push rod 311. During the process of the baffle plate 212 sliding leftward, it contacts and pushes the power push rod 311 to slide leftward. At this time, the sliding push rod 312 cannot be displaced under the restriction of the limit clamping block 315 on the limit clamping shaft 314. The sliding push rod 312 extends into the power push rod 311. As Figure 6In the embodiment, the surface of the power push rod 311 is fixedly connected with an adjusting push shaft 317, the inner sliding connection of the outer frame 1 is limited to a block 315, the inner fixed connection of the outer frame 1 is a No. 2 spring 316, the No. 2 spring 316 is fixedly connected to the limit block 315, one end of the sliding push rod 312 is fixedly connected with a telescopic push shaft 318, the inner fixed connection of the outer frame 1 is a No. 3 spring 319, the No. 3 spring 319 is fixedly connected to the sliding push rod 312, the inner rotation connection of the outer frame 1 is a power shaft 3110, the surface of the power shaft 3110 is provided with a power groove, the telescopic push shaft 318 is slidably connected to the inside of the power groove on the surface of the power shaft 3110, one end surface of the power shaft 3110 is fixedly connected with a No. 1 circular plate 3111, the inner part of the outer frame 1 The second circular plate 3113 is rotatably connected, and the surface of the second circular plate 3113 and the first circular plate 3111 is connected with a transmission track 3112. The inner part of the outer frame 1 is rotatably connected with the third circular plate 3116, and the third circular plate 3116 is coaxial with the second circular plate 3113. When the shielding plate 212 completely blocks the left filter screen plate 211, the push shaft 317 is adjusted to give an upward thrust to the inner wall inclined surface of the limit card block 315, and the limit card block 315 slides upward, and the limit card block 315 is separated from the sliding path of the limit card shaft 314. The sliding push rod 312 slides to the left under the push of the first spring 313, and gives a thrust to the inclined surface of the power slot of the power shaft 3110 through the telescopic push shaft 318, thereby pushing the power shaft 3110 to rotate. And drive the No. 1 circular plate 3111 to rotate synchronously, the rotation of the No. 1 circular plate 3111 drives the No. 2 circular plate 3113 to rotate through the transmission track 3112, the No. 3 circular plate 3116 rotates synchronously with the No. 2 circular plate 3113, the surface of the No. 3 circular plate 3116 is fixedly connected with a toggle shaft 3115, the inner rotation connection of the outer frame 1 is connected with a toggle rod 3114, the surface of the toggle rod 3114 is provided with a rotation groove, the toggle shaft 3115 is slidably connected to the inside of the rotation groove of the toggle rod 3114, the one side surface of the filter screen plate 211 is fixedly connected with a contact shaft 3118, the contact shaft 3118 is in contact with the surface of the toggle rod 3114, the storage box 3117 is slidably connected to the inside of the outer frame 1, the storage box 3117 is located below the filter screen plate 211, and is received by the toggle shaft 31 15 gives a thrust to the inner wall of the toggle rod 3114, thereby driving the toggle rod 3114 to swing back and forth around the end away from the third circular plate 3116, thereby giving an upward force to the abutment shaft 3118, pushing the filter screen plate 211 to slide upward. When the filter screen plate 211 slides to the top, the filter screen plate 211 slides downward under the drive of its own gravity, and the top plate of the filter screen plate 211 collides with the top of the filter screen sliding frame, thereby driving the filter screen plate 211 to vibrate up and down. Through the vibration and the inertia of the impurities on the surface of the filter screen plate 211, the impurities on the surface of the filter screen plate 211 fall into the storage box 3117 for centralized collection. The automatic cleaning of the filter screen plate 211 through vibration can automatically remove dust and particulate matter on the filter screen plate 211 without manual intervention.Greatly simplifies the cleaning and maintenance work.

[0038] Such as Figure 8 In it, the loosening mechanism 4 includes a bottom-contact sliding shaft 411, and the bottom-contact sliding shaft 411 is slidably connected to the inside of the shielding plate 212. When the switching mechanism 2 that vibrates the filter screen plate 211 by swinging the toggle rod 3114 back and forth, the toggle rod 3114 swings upward, and by giving an upward thrust to the bottom-contact sliding shaft 411, such as Figure 10 In it, a power rack 412 is slidably connected to the inside of the shielding plate 212. A fixed connection is provided between the power rack 412 and the bottom-contact sliding shaft 411. A power gear 413 is rotatably connected to the inside of the switching mechanism 2. The power gear 413 is meshed with the power rack 412. A swing rod 416 is rotatably connected to the inside of the shielding plate 212. A power rotating rod 414 is rotatably connected to the surface of the power gear 413. A rotating frame 415 is rotatably connected to the surface of the power rotating rod 414. The swing rod 416 is slidably connected to the inside of the rotating frame 415, thereby pushing the power rack 412 to slide upward, and driving the power rotating rod 414 to rotate through the power gear 413. The rotation of the power rotating rod 414 gives an outward pulling force to the swing rod 416 through the rotating frame 415 on the surface. The swing rod 416 rotates clockwise inside the switching mechanism 2, and the rubber pad on the surface of the swing rod 416 contacts the filter screen on the surface of the filter screen plate 211. And when the power rotating rod 414 rotates to the bottom end, the swing rod 416 is pulled back into the switching mechanism 2 through the rotating frame 415. The impurities on the surface of the filter screen plate 211 are slapped by driving the swing rod 416 to swing back and forth by the toggle rod 3114, so as to loosen the impurities on the surface of the filter screen plate 211, and then facilitate the cleaning mechanism 3 to vibrate the impurities on the surface of the filter screen plate 211 into the inside of the storage box 3117, improving the cleaning efficiency of the surface of the filter screen plate 211.

[0039] The following is the entire working process and principle of the above embodiments: A wind sensor is provided between the filter sieve plate 211 and the heat exchange chamber 105. An electric telescopic rod is fixedly connected to the surface of the baffle plate 212. When the wind force passing through the filter sieve plate 211 drops to a certain threshold, the electric telescopic rod pushes the baffle plate 212 to slide leftward, closing the blocked filter sieve plate 211, and then proceeding with subsequent cleaning or disassembly. At the same time, the unblocked filter sieve plate 211 is exposed, enabling the device to still operate normally during the cleaning of the filter screen. Even during the cleaning of the filter sieve plate 211, users can still enjoy continuous ventilation and air purification without stopping the air conditioning system, ensuring the continuity of indoor air quality. At the same time, during the leftward sliding of the baffle plate 212, it contacts and pushes the power push rod 311 to slide leftward. At this time, the sliding push rod 312 cannot displace under the restriction of the limit card block 315 on the limit card shaft 314. The sliding push rod 312 extends into the interior of the power push rod 311. When the baffle plate 212 completely blocks the left filter sieve plate 211, the adjusting push shaft 317 gives an upward thrust to the inner wall slope of the limit card block 315. The limit card block 315 slides upward, and the limit card block 315 disengages from the sliding path inside the limit card shaft 314. The sliding push rod 312 slides leftward under the push of the first spring 313, and gives a thrust to the inclined part of the power groove of the power rotating shaft 3110 through the telescopic push shaft 318, thereby pushing the power rotating shaft 3110 to rotate, and driving the first circular plate 3111 to rotate synchronously. The rotation of the first circular plate 3111 drives the second circular plate 3113 to rotate through the transmission track 3112. The third circular plate 3116 rotates synchronously with the second circular plate 3113, and gives a thrust to the inner wall of the toggle rod 3114 through the toggle shaft 3115, thereby driving the toggle rod 3114 to swing back and forth around the end far from the third circular plate 3116, and then giving an upward force to the abutment surface shaft 3118, pushing the filter sieve plate 211 to slide upward. When the filter sieve plate 211 slides to the top, the filter sieve plate 211 slides downward under its own gravity. The top plate of the filter sieve plate 211 collides with the top of the filter screen frame, thereby driving the filter sieve plate 211 to vibrate up and down. And through the vibration and the inertia of the impurities on the surface of the filter sieve plate 211, the impurities on the surface of the filter sieve plate 211 fall into the storage box 3117 for centralized collection. Automatically cleaning the filter sieve plate 211 can automatically remove dust and particulate matter on the filter sieve plate 211 without manual intervention, greatly simplifying the cleaning and maintenance work, and the automatic cleaning of the filter sieve plate 211 can continuously keep the indoor air clean and reduce indoor air pollution.

[0040] At this time, during the process that the toggle lever 3114 swings back and forth to vibrate the filter screen plate 211 in the switching mechanism 2, when the toggle lever 3114 swings upward, it gives an upward thrust to the abutting surface sliding shaft 411, thereby pushing the power rack 412 to slide upward, and drives the power rotating rod 414 to rotate through the power gear 413. The rotation of the power rotating rod 414 gives an outward pulling force to the swing rod 416 through the rotating frame 415 on the surface. The swing rod 416 rotates clockwise inside the switching mechanism 2, and the rubber pad on the surface of the swing rod 416 contacts the filter screen on the surface of the filter screen plate 211. When the power rotating rod 414 rotates to the bottom end, the swing rod 416 is pulled back into the switching mechanism 2 through the rotating frame 415. The toggle lever 3114 drives the swing rod 416 to swing back and forth to pat the impurities on the surface of the filter screen plate 211, thereby loosening the impurities on the surface of the filter screen plate 211, and then facilitating the cleaning mechanism 3 to vibrate the impurities on the surface of the filter screen plate 211 into the interior of the storage box 3117, improving the cleaning efficiency of the surface of the filter screen plate 211.
