The technical problem to be solved by the utility model is to provide a ceiling-mounted heat recovery and purification fresh air ventilator, which has a simple structure and completely solves the problem that the purification fresh air ventilator emits peculiar smell when it runs again.

The technical solution adopted by the utility model to solve the technical problem is as follows: a ceiling-mounted heat recovery and purification fresh air ventilator is provided, which includes a body and an exhaust fan, and one end of the body is divided into an air cavity I and an air cavity. III, the inside of the other end of the body is divided up and down into an air cavity II and an air cavity V, and the air cavity V and the air cavity I are connected through the heat exchange core in the middle of the body, and the heat exchange core is The upper side is communicated with the air cavity II, and the lower side is communicated with the air cavity IV. The air cavity I, the air cavity III, the air cavity II and the air cavity V are respectively connected with the air outlet I, the air outlet III, the air outlet II and the air valve on the outside of the body. I is connected, the air cavity I is equipped with a fresh air fan, a heating component and a multi-layer filter screen connected to the air outlet I, between the air cavity III and the air cavity IV and between the air cavity II and the air cavity V. They are connected through the air valve III and the air valve II respectively.

As a supplement, a high-efficiency filter screen and an activated carbon filter screen are installed in sequence from left to right in the position connected to the heat exchange core inside the air cavity I.

Preferably, a pre-filter screen is installed at the position where the heat exchange core communicates with the air cavity IV and the air cavity V.

Further, the heating component is a PTC heater.

Beneficial effects: The utility model relates to a ceiling-type heat recovery and purification fresh air ventilator, which has a simple and reasonable structure, and has three sealing valves and a PTC heating pipe in coordination with a specially designed air cavity and a special electric control, which completely solves the problem of purifying fresh air. The problem of odor when the ventilator is running again.

Detailed ways

The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

As shown in Figures 1-3, the embodiment of the present utility model relates to a ceiling-type heat recovery and purification fresh air ventilator, including a body 1 and an exhaust fan 15. One end of the body 1 is divided into an air cavity up and down. I6 and air cavity III4, the other end of the body 1 is divided into air cavity II16 and air cavity V11 up and down, and the air cavity V11 and the air cavity I6 are connected through the heat exchange core 9 in the middle of the body 1, so The upper side of the heat exchange core 9 is communicated with the air cavity II16, and the lower side is communicated with the air cavity IV8. 2. The tuyere III3, the tuyere II14 and the air valve I12 communicate with each other. The air cavity I6 is equipped with a fresh air fan 5 connected to the air cavity I2, the heating element 19 and the multi-layer filter screen. The air cavity III4 is connected with the air cavity IV8. Between them and between the air chamber II16 and the air chamber V11 are connected through the air valve III7 and the air valve II13 respectively.

As a supplement, a high-efficiency filter screen 18 and an activated carbon filter screen 17 are installed in sequence from left to right in the position where the air cavity I6 communicates with the heat exchange core 9 .

Preferably, a pre-filter screen 10 is installed at the position where the heat exchange core 9 communicates with the air cavity IV8 and the air cavity V11.

Further, the heating component 19 is a PTC heater.

As an embodiment of the present utility model:

Exhaust principle: As shown in Figure 1, start the fan, open the air valve III7, close the air valve II13, and the indoor air enters the air chamber III4 through the air valve III7 through the indoor exhaust duct and enters the air chamber IV8 through the pre-filter screen. 10. The heat exchange core 9 enters the air cavity II16, and is discharged to the outside by the exhaust fan 15 through the air outlet II14 through the connecting pipe.

Principle of purifying fresh air: As shown in Figure 2, start fresh air fan 5, open air valve I12, close air valve II13, outdoor fresh air enters air cavity V11 through air valve I12, and the air is filtered through pre-filter 10, heat exchange core 9, and activated carbon. The net 17 and the high-efficiency filter 18 enter the air cavity I6, and are sent into the indoor fresh air duct by the fresh fan through the air outlet I2. The air cavity I6 is equipped with a PTC heater to heat the fresh air in winter.

Filter self-cleaning principle: As shown in Figure 3, start the exhaust fan 15, open the air valve II13, close the air valve III7 and the air valve I12, the indoor air passes through the indoor fresh air duct from the air outlet I2, and the fresh air fan cavity enters the air cavity I6, The indoor air heated by the PTC enters the air cavity V11 through the high-efficiency filter screen 18, the activated carbon filter screen 17, the heat exchange core 9 and the pre-filter screen 10. The heated indoor air dehumidifies and dries the filter screen and the heat exchange core 9, and is specially heated The air regenerates the activated carbon filter 17, and the high-speed air blows back on the pre-filter to positively absorb the large particles of dust and harmful gases and odors released by the activated carbon. Drain outside.

The utility model has a simple and reasonable structure, and has three sealing valves and a PTC heating pipe in cooperation with a specially designed air cavity and a special electric control, which completely solves the problem of odors emitted when the purifying fresh air ventilator runs again.
