Description

An indoor fresh air purifier

technical field

The utility model belongs to air purification equipment, in particular to an indoor fresh air purifier.

Background technique

The fresh air purifier is a kind of air purification equipment that can circulate the indoor air. It discharges the indoor dirty air to the outside, and at the same time, the outdoor fresh air is sterilized, disinfected, filtered and other measures, and then input into the room, so that the room There is fresh and clean air all the time. The fresh air purifier achieves convection of indoor air through independent air supply and induction, thereby maximizing indoor air replacement.

At present, fresh air purifiers on the market, when installed in a closed room, enter the box by sucking indoor air and outdoor air, and the outdoor air is exchanged by the heat exchange box in the box and becomes fresh air, which is sent into the room from the air supply port. Indoor air enters the box from the exhaust port and is discharged to the outside after heat exchange by the heat exchange box. Because the indoor and outdoor are two completely different environmental systems, the dirty air outside will inevitably penetrate into the room through doors, windows, holes, etc. Then pollute the clean air that has been treated in the room, which greatly affects the purification efficiency of the fresh air purifier.

Utility model content

The purpose of the utility model is to provide an indoor fresh air purifier which can make the indoor air pressure higher than the outdoor and improve the air purification efficiency.

The technical scheme adopted by the utility model to solve the technical problem is: an indoor fresh air purifier, including a box body and a heat exchange box, a blower fan and an exhaust fan arranged in the box body, and a heat exchanger is arranged in the heat exchange box. The upper and lower side walls of the box body are respectively provided with an air supply port and an air exhaust port, and the right side wall of the box body is provided with an upper side wall pipe interface and a lower side wall pipe interface in turn, the air supply fan is arranged on the upper side of the box body, and the exhaust fan It is located on the lower side of the box body, the heat exchange box is located between the blower fan and the exhaust fan, there is a filter cavity between the blower fan and the air supply port, a filter is installed in the filter cavity, and a sealing partition is set between the blower fan and the exhaust fan , the sealing partition and the box body form two airtight chambers respectively accommodating the air blower and the air outlet, the airtight chambers are respectively communicated with the heat exchange box, and the speed of the air blower is higher than that of the exhaust fan.

The indoor fresh air purifier described above has a high-efficiency filter, and a primary-effect filter is provided between the heat exchange box and the lower side wall pipe interface.

In the above-mentioned indoor fresh air purifier, an upper back pipe interface adjacent to the upper side wall pipe interface is opened on the back panel of the box body, and a lower back pipe interface adjacent to the upper side wall pipeline interface is opened on the back panel of the box body. pipe interface.

The described indoor fresh air purifier has an outdoor temperature sensor between the primary effect filter and the heat exchange box, an exhaust pipe is provided between the exhaust fan and the heat exchange box, and the exhaust fan and the exhaust pipe There is an indoor temperature sensor between them.

The said indoor fresh air purifier is equipped with an indoor CO2 sensor and an indoor humidity sensor in the exhaust pipe.

The said indoor fresh air purifier has a fresh air temperature sensor between the heat exchange box and the blower.

The beneficial effect of the utility model is: the speed of the blower fan is greater than that of the exhaust fan, so that the fresh air volume is greater than the exhaust air volume. When the total amount of clean air entering the room is greater than the total amount of air discharged outside, the indoor air pressure is also greater than the outdoor air pressure. The indoors form an effective positive pressure environment relative to the outdoors. In this environment, the indoor air leaks to the outdoors through doors, windows, holes, etc., and the outdoor atmospheric pressure is lower than the indoor air. It is higher than the outside, and the excess clean air can stay in the closed room, which can provide higher purification efficiency than the existing fresh air purifier.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, the utility model discloses an indoor fresh air purifier, comprising a box body 1 and a heat exchange box 2, a blower 3 and an exhaust fan 4 arranged in the box body 1, the heat exchange box 2 is provided with a heat exchange box An exchanger, the upper and lower side walls of the box 1 are respectively provided with an air supply port 14 and an air exhaust port 5, the air exhaust port 5 is used to suck indoor air into the box body 1, and the air supply port is used to suck the fresh air in the box body 1 Into the room, the right side wall of the box body 1 is provided with an upper side wall pipeline interface 15 and a lower side wall pipeline interface 7 in turn, the upper side wall pipeline interface 15 is used to discharge the air from the outside, and the lower side wall pipeline interface 7 is used to discharge the air from the outside. Air suction, the blower 3 is arranged on the upper side of the box body 1, the exhaust fan 4 is arranged on the lower side of the box body 1, the heat exchange box 2 is arranged between the blower 3 and the exhaust fan 4, and between the blower 3 and the air outlet 14 A filter chamber 9 is provided, and a filter is installed in the filter chamber 9, and a sealing partition 16 is provided between the blower 3 and the exhaust fan 4, and the sealing partition 16 and the box body 1 together with the heat exchange box 2 form two airtight chambers room, the air blower 3 and the exhaust fan 4 are respectively located in two airtight chambers, and the airtight chambers communicate with the heat exchange box 2 respectively, and the speed of the air blower 3 is greater than that of the air exhauster 4, and the speed of the two air blowers passes through Control the voltage at both ends of the DC brushless motor to achieve. Since the air sent by the blower 3 comes from the suction of the air outlet 5 and the lower side wall pipe interface 7 respectively, when the speed of the blower 3 is relatively high, the air volume (fresh air volume) ) is greater than the exhaust air volume.
