Description

Technical Field

[0001] The utility model relates to the technical field of fresh air equipment, in particular to an air conditioner fresh air integrated machine with a bypass structure. Background Art

[0002] Traditional heat exchange structures, such as Figure 1 shown, add an extra channel at the upper part of the machine as shown in Figure 1 for the bypass function. Since the extra channel increases the size of the machine, and because the added bypass is separated from the heat exchange by foam, there is a possibility of air leakage. Content of the Utility Model

[0003] The utility model provides an air conditioner fresh air integrated machine with a bypass structure to solve the problems that the bypass structure of the existing fresh air system is unreasonably set, resulting in an oversized integrated machine and some bypasses being false bypasses.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: an air conditioner fresh air integrated machine with a bypass structure, including a machine shell, a partition board, a circulation fan and a heat exchanger located on one side of the partition board, a heat exchange core, a fresh air fan and an exhaust fan located on the other side of the partition board. A bypass structure is provided on one side of the heat exchange core, and a wind valve is installed on one side of the bypass structure. An air outlet, a circulation air inlet, a fresh air inlet, an exhaust air inlet, an exhaust air outlet and a fresh air outlet are provided on the machine shell, and a bypass air outlet and a fresh air outlet are provided on the partition board.

[0005] Preferably, the fresh air inlet and the exhaust air outlet are arranged on the same side of the housing, the fresh air inlet is adjacent to the wind valve, and the exhaust air outlet is adjacent to the exhaust fan.

[0006] Preferably, the exhaust air inlet and the circulation air inlet are arranged on the same side of the housing, the exhaust air inlet is located on one side of the partition board and adjacent to the wind valve, and the circulation air inlet is located on the other side of the partition board and opposite to the circulation fan.

[0007] Preferably, the air outlet is arranged on the machine shell adjacent to the heat exchanger side, and the air outlet is opposite to the fresh air inlet and the exhaust air outlet.

[0008] Preferably, an indoor temperature sensor is installed at the position of the exhaust air inlet.

[0009] Preferably, an outdoor temperature sensor is installed at the position of the fresh air inlet.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: A bypass structure is added on one side of the heat exchange core. Fresh air enters from the fresh air inlet, passes through the air valve and the bypass structure, and then enters the air-conditioning part through the bypass air outlet on the partition board. After heat exchange through the heat exchanger, it is directly blown into the room, increasing the fresh air volume. The position of the bypass structure is reasonably designed, and there is no need to increase the size of the casing. Moreover, there is no need to use foam to block between the bypass structure and the heat exchange core, and there is no possibility of air leakage. Temperature sensors are provided at the fresh air inlet and the exhaust air inlet. According to the indoor and outdoor temperatures and the temperature difference, the opening of the air valve can be automatically controlled to save energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 2-3 , the present embodiment provides the following technical solutions: An air-conditioning fresh air integrated machine with a bypass structure includes a casing 1, a partition board 2, a circulation fan 3 and a heat exchanger 4 located on one side of the partition board 2, a heat exchange core 5, a fresh air fan 6 and an exhaust air fan 7 located on the other side of the partition board 2. A bypass structure 8 is provided on one side of the heat exchange core 5, an air valve 9 is installed on one side of the bypass structure 8, an air outlet 10, a circulation air inlet 11, a fresh air inlet 12, an exhaust air inlet 13 and an exhaust air outlet 14 are provided on the casing 1, and a bypass air outlet 21 and a fresh air outlet 22 are provided on the partition board 2.

[0017] As a preferred embodiment of this embodiment, the fresh air inlet 12 and the exhaust air outlet 14 are arranged on the same side of the housing 1. The fresh air inlet 12 is adjacent to the air valve 9, and the exhaust air outlet 14 is adjacent to the exhaust air fan 7.

[0018] As a preferred embodiment of this embodiment, the exhaust air inlet 13 and the recirculated air inlet 11 are arranged on the same side of the housing 1. The exhaust air inlet 13 is located on one side of the partition 2 and is adjacent to the air valve 9, and the recirculated air inlet 11 is located on the other side of the partition 2 and is opposite to the recirculated air fan 3.

[0019] As a preferred embodiment of this embodiment, the air outlet 10 is arranged on the housing 1 adjacent to one side of the heat exchanger 4, and the air outlet 10 is opposite to the fresh air inlet 12 and the exhaust air outlet 14.

[0020] As a preferred embodiment of this embodiment, an indoor temperature sensor (not shown in the figure) is installed at the position of the exhaust air inlet 12.

[0021] As a preferred embodiment of this embodiment, an outdoor temperature sensor (not shown in the figure) is installed at the position of the fresh air inlet 12.

[0022] As Figure 3As shown, the all-in-one machine in this embodiment has three working modes: 1. Air conditioner + fresh air mode; 2. Fresh air mode; 3. Air conditioner mode. When the all-in-one machine is in the air conditioner + fresh air mode, fresh air enters the machine housing 1 through the fresh air inlet 12 under the action of the fresh air fan 6, then exchanges heat through the heat exchange core 5 and enters the other part of the housing 1 through the fresh air outlet 22 of the partition 2, and is sent to the room through the air outlet 10 after heat exchange through the heat exchanger 4. A part of the circulating air enters the housing 1 through the circulating air inlet 11 under the action of the circulating fan 3, and is blown out from the air outlet 10 to cool or heat the room after heat exchange through the heat exchanger 4. Another part of the circulating air enters the housing 1 from the exhaust air inlet 13 under the action of the exhaust fan 7 and is discharged from the exhaust air outlet 14. When the all-in-one machine is in the air conditioner mode, only the circulating air enters the machine housing 1 through the circulating air inlet 11, is cooled or heated for the room through heat exchange by the heat exchanger 4, and is blown out from the air outlet 10. When the all-in-one machine is in the fresh air mode, fresh air enters the machine housing 1 from the fresh air inlet 12, exchanges heat through the heat exchange core 5, enters the other half of the housing 1 through the fresh air outlet 22 of the partition 2, and is sent to the room after heat exchange through the heat exchanger 4. The return air enters the machine housing 1 through the exhaust air inlet 13 and is discharged from the exhaust air outlet 14 under the action of the exhaust fan 7. In the fresh air mode, when the main control board of the all-in-one machine detects that the indoor temperature Ti collected by the indoor temperature sensor is 20°C ≤ Ti ≤ 28°C, the outdoor temperature collected by the outdoor temperature sensor is 20°C ≤ To ≤ 28°C, and the indoor-outdoor temperature difference ≤ 2°C, the control air valve 9 is automatically opened, and fresh air can enter the other side of the housing 1 through the bypass structure 8 and the bypass air outlet 21 of the partition 2. The specific structure of the air valve 9 can adopt the air valve box described in the patent CN217817233U, and the air damper is controlled by a motor to realize the automatic opening and closing of the air valve.

The scope of the present invention is defined by the appended claims and their equivalents.
