Embodiment 1

[0050] Embodiment 1 of the present invention is as figure 1 , 2 , 3 shown. This example is an indoor air purifier with indoor and outdoor ventilation functions, including a casing 10 , a cleaning element and a fan device 30 placed in the casing.

[0051] The purification element is a purification heat exchanger 20 with heat exchange function;

[0052] The casing 10 is provided with a purification heat exchange cavity, and the purification heat exchanger 20 is arranged in the purification heat exchange cavity; the casing wall has a return air port 11 and an air supply port 12 connected to the room, and a fresh air port 13 connected to the outside and the exhaust port. Air outlet 14; between the air outlet 13 and the air exhaust outlet 14 of the sealed motor 174 in the casing, an air passage 18 communicating with them is provided.

[0053] Described purifying heat exchanger 20 comprises filter element 22 and the frame that supports them, and filter element is made of air filt...

Embodiment 2

[0065] Embodiment 2 of the present invention is as Figure 4 shown. This example includes the casing 10, the purification element and the blower device 30 placed in the casing the same as the example 1. The purification heat exchanger 20 is also a wheel-type purification heat exchanger similar to Example 1, and the basic structure of Example 1 is also retained in the purification heat exchange chamber in the casing 10 . The main differences from Example 1 are:

[0066] The fan device is a more compact long-axis fan device 30A arranged on both sides of the purification and heat exchange runner. Its wind wheel motor 33 is a long-axis motor 33A whose output shaft protrudes from both ends. The central axis 21 of the wheel is combined into one, and the purification heat exchange runner is supported by the shell of the long-axis motor 33A and rotates around it; the fresh air wind wheel 31 is placed in the right front chamber 101 and the left front chamber 103, and its air inlet is...

Embodiment 3

[0072] Embodiment 3 of the present invention is as Figure 5 shown. This example is used in a well-sealed room. The fan device only uses one wind wheel, and the other wind wheel is realized by the difference in indoor and outdoor air pressure. Generally, it is hoped that the room maintains a certain positive pressure to prevent untreated air from entering the room. It is more reasonable to keep the fresh air wind wheel and save the exhaust wind wheel. The purifying heat exchanger 20 of this structure is still a wheel-type purifying heat exchanger, including a central shaft 21, a filter element 22 and a runner motor 23, and the filter element 22 is a disc-shaped purifying heat-exchanging runner 22C; It is a single wind wheel fan device 30B, including a flat motor 33B and a fresh wind wheel 31 fixed on its output shaft. The fresh air wheel 31 is placed in the right front chamber 101 and the left front chamber 103, and its air inlet communicates with the right front chamber 101...

Abstract

An indoor air purifier with an indoor and outdoor air exchange function comprises a housing, a purifying component and a fan device, wherein the purifying component and the fan device are arranged in the housing. The purifying component is a purifying heat exchange with a heat exchange function, the wall of the housing is provided with an air return port and an air feed port communicated with the interior and a fresh air port and an air exhaust port communicated with the exterior, an air channel 18 and a sealing door are arranged between the fresh air port and the air exhaust port and communicate the same, and the sealing door is used for exchanging air and switching internal-circulating working conditions. The purifying heat exchanger is a wheel type heat storage purifying heat exchanger or a fixed type heat storage purifying heat exchanger, and cartridges of them are made of air filter materials and exchange heat with the air by directly contacting when the air passes, and an air conditioner for recovery and exhaust can purify and filter the air. The indoor air purifier overcomes conflict in indoor air purification and indoor and outdoor ventilation and air exchange and thoroughly eliminates the severe defect that an existing indoor air purifier cannot refresh indoor air components and cannot eliminate such harmful gases as carbon monoxide and excessive carbon dioxide and the like, loss of ventilation and heat exchange air conditioning energy is greatly reduced, and a novel technology is provided for health care, environmental protection and energy conservation.

Description

technical field [0001] The invention relates to an air treatment device for purifying indoor air, in particular to an air purifier capable of updating indoor air through indoor and outdoor ventilation. Background technique [0002] There are many types of existing indoor air purifiers, most of which can only filter out suspended solid particles in the indoor air, and a few are equipped with various purification components such as antibacterial catalysts, activated carbon, and negative ions, which can absorb or kill airborne particles. Part of the bacteria and a small amount of harmful gases such as decomposing formaldehyde, but it is almost helpless to control the harm of most organic volatiles VOC and second-hand smoke produced by cigarettes, especially for carbon monoxide and excessive carbon dioxide, which are not conducive to health and even harmful to human body Due to the limited dust holding capacity of the purifier, the method of opening windows for ventilation can...
