Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a silent ventilator provided with a multi-effect filtering structure. Background Art

[0002] The fresh air ventilator is designed and developed based on the principle that air is supplied on one side of a closed room and induced on the other side, which will form a fresh air flow plant in the room. It relies on mechanical air supply and induction to force the formation of a fresh air flow field in the system. It is a new type of environmentally friendly appliance that keeps the indoor air clean and fresh at all times. The fresh air ventilator can be divided into ceiling-mounted, wall-mounted, and floor-standing types according to the fixing method. Among them, the ceiling-mounted fresh air ventilator is hidden in the ceiling, so it is more beautiful and has a high utilization rate.

[0003] At present, the filtering method of traditional fresh air ventilators is too simple. After long-term use, the air filtering effect of the filtering device in the fresh air ventilator will gradually decrease, which will reduce the use effect of the fresh air ventilator over time. Utility Model Content

[0004] The purpose of the present invention is to provide a silent ventilator with a multi-effect filtering structure to solve the problem that the filtering method proposed in the above background technology is too single.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a silent ventilator with a multi-effect filtering structure, comprising an outer shell, the interior of which is divided into four parts by a partition plate, and characterized in that it also includes a heat exchanger, which is fixedly mounted on the bottom surface of the inner wall of the outer shell, and the heat exchanger is located in the middle of the partition plate, and a multi-effect filtering structure is installed inside the outer shell, and the multi-effect filtering structure can pass through the fresh air inlet so that the fresh air can be filtered in sequence through the primary filter, the activated carbon filter and the ozone filter.

[0006] Preferably, the multi-effect filtering structure includes a fresh air inlet, which is installed on the side surface of the shell, and the fresh air inlet corresponds to the primary filter. The primary filter is fixedly installed on the bottom surface of the inner wall of the shell, and the front and rear sides of the primary filter are respectively fixedly connected to the front surface of the inner wall of the shell and the front surface of the partition plate. The side surface of the primary filter is connected to an air duct, and the other end of the air duct corresponds to the activated carbon filter. The other side surface tube of the shell is installed with a fresh air outlet, and the side surface of the shell is also installed with an old air outlet, and the other side of the shell is installed with an old air inlet, and a fan is installed on the inner wall surface of the shell corresponding to the fresh air outlet and the old air outlet, and an ozone filter is fixedly installed on the side of the fan.

[0007] By adopting the above technical solution, fresh air can pass through the primary filter and then enter the activated carbon filter under the guidance of the air duct, so that the fresh air is quickly filtered.

[0008] Preferably, the heat exchanger symmetrically divides the four parts separated by the partition plate inside the shell into two parts that are not ventilated to each other.

[0009] The above technical solution makes the fresh air and old air circulation paths relatively independent.

[0010] Preferably, the old air inlet and the fresh air outlet are located on the same side.

[0011] Adopting the above technical solution facilitates indoor ventilation.

[0012] Preferably, a noise reduction and silencing structure is also installed inside the shell, and the noise reduction and silencing structure can reduce vibration when the fan is running through the fixing block and isolate noise at the same time with the sound insulation board.

[0013] The above technical solution is adopted to achieve silent operation and improve user comfort.

[0014] Preferably, the noise reduction and silencing structure includes sound-absorbing cotton, which is embedded in the interlayer of the outer shell. A sound insulation board is fixedly connected to the other side of the fan, and the sound insulation board encloses the enclosed sound insulation board. A fixed block is installed on the outer surface of the sound insulation board, and the fixed block clamps the fan.

[0015] By adopting the above technical solution, the noise of the fan cannot be transmitted through the sound insulation board.

[0016] Preferably, an opening is provided on one side of the sound insulation board.

[0017] The adoption of the above technical solution makes it easier for the fan to draw airflow.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the silent ventilator with a multi-effect filtering structure:

[0019] 1. When the silent ventilation machine with multi-effect filtering structure flows fresh air, first, the fan corresponding to the fresh air outlet is turned on, so that the fan draws the outdoor air through the fresh air inlet. Then, the outdoor fresh air will first pass through the primary filter for filtration and then flow through the air duct into the activated carbon filter for further filtration.

[0020] 2. Furthermore, the fresh air will pass through the activated carbon filter and then pass through the heat exchanger. After the heat exchanger exchanges heat with the old air, it reaches the partition where the fan is located. The airflow will then pass through the ozone filter to adsorb ozone, making the fresh air quality better.

[0021] 3. Furthermore, when the fan is started, it will vibrate and generate noise. At this time, the fan can be clamped by a fixed block to reduce the amplitude of the fan. By setting a sound insulation board on the periphery of the fan, the volume is reduced and transmitted, and then the sound-absorbing cotton clamped in the outer shell further absorbs the noise, making the user experience of the ventilator better.

Example 1

[0031] The ventilator is equipped with a multi-effect filtering structure, which can improve the quality of fresh air entering the room through multiple filtering structures. Specifically:

[0032] The interior of the housing 1 is divided into four parts by a partition plate 11, and also includes a heat exchanger 10. The heat exchanger 10 is fixedly mounted on the bottom surface of the inner wall of the housing 1, and the heat exchanger 10 is located in the middle of the partition plate 11. A multi-effect filtering structure is installed inside the housing 1. The multi-effect filtering structure can pass through the fresh air inlet 2 so that the fresh air can be filtered in sequence through the primary filter 4, the activated carbon filter 6 and the ozone filter 7 after entering. The multi-effect filtering structure includes a fresh air inlet 2, which is installed through the side surface of the housing 1. The fresh air inlet 2 corresponds to the primary filter 4. The primary filter 4 is fixedly mounted on the bottom surface of the inner wall of the housing 1, and the front and rear sides of the primary filter 4 are respectively at The front surface of the inner wall of the shell 1 is fixedly connected to the front surface of the partition plate 11, the side surface of the primary filter 4 is connected to the induced air duct 5, the other end of the induced air duct 5 corresponds to the activated carbon filter 6, the other side surface of the shell 1 is installed with a fresh air outlet 3, the side surface of the shell 1 is also installed with an old air outlet 8, and the other side of the shell 1 is installed with an old air inlet 9, the inner wall surface of the shell 1 corresponding to the fresh air outlet 3 and the old air outlet 8 is installed with a fan 15, and an ozone filter 7 is fixedly installed on the side of the fan 15, the heat exchanger 10 symmetrically divides the four parts separated by the partition plate 11 inside the shell 1 into two non-ventilated parts, and the old air inlet 9 and the fresh air outlet 3 are located on the same side;

[0033] When the ventilator is changing air, first, Figure 4 As shown, the heat exchanger 10 installed inside the shell 1 is connected to a partition plate 11, which separates the flow path of fresh air and the flow path of old air through the partition plate 11. First, the two fans 15 are turned on, so that the fan 15 corresponding to the fresh air outlet 3 draws the outdoor fresh air into the shell 1 through the fresh air inlet 2, and then the air flow will first pass through the primary filter 4, so that the dust in the air is adsorbed, and then the air flow will enter the side surface of the primary filter 4 connected to the air duct 5. Since the other end of the air duct 5 corresponds to the activated carbon filter 6, the air flow will enter the activated carbon filter 6, and the harmful gases in the air will be adsorbed by the activated carbon filter 6 to remove the odor in the air. Then, after the air passes through the activated carbon filter 6, it will enter the heat exchanger 10. At the same time, the fan 15 corresponding to the old air outlet 8 is turned on, so that the old air inlet 9 draws the indoor air into the shell 1, and it will first pass through the primary filter 4, and then circulate through the heat exchanger 10. The fresh air and the old air exchange heat, and then reach the partition part corresponding to the old air outlet 8. After being filtered by the ozone filter 7, the old air is discharged through the old air outlet 8. At the same time, the fresh air after heat exchange will enter the partition part corresponding to the fresh air outlet 3, and then the fresh air will pass through the ozone filter 7 to remove ozone, so that the air quality entering the room is better. Example 2

[0034] The ventilator is equipped with a noise reduction and silent structure, which controls the vibration of the fan 15 through the fixing block 14 and reduces the noise with the sound insulation board 12, specifically:

[0035] A noise reduction and silencing structure is also installed inside the housing 1. The noise reduction and silencing structure can reduce vibration when the fan 15 is in operation through a fixing block 14 and cooperate with the sound insulation board 12 to isolate noise. The noise reduction and silencing structure includes sound-absorbing cotton 13, which is embedded in the interlayer of the housing 1. The other side of the fan 15 is fixedly connected to the sound insulation board 12, and the sound insulation board 12 encloses the enclosed sound insulation board 12. A fixing block 14 is installed on the outer surface of the sound insulation board 12, which clamps the fan 15. An opening is provided on one side of the sound insulation board 12.

[0036] After the fan 15 is turned on, the vibration of the fan 15 will first be limited by the fixing block 14 to reduce the amplitude after the fan 15 is turned on. At the same time, the sound insulation board 12 will enclose the enclosed sound insulation board 12, and the noise generated by the fan 15 will be isolated by the sound insulation board 12. The sound insulation board 12 on the side connected to the fan 15 is provided with an opening to facilitate air flow, and part of the noise is transmitted outward. At this time, the sound-absorbing cotton 13 inside the interlayer of the outer shell 1 absorbs the excess noise, thereby making the ventilator noise-reducing and quiet, and improving the comfort of the user experience.

[0037] Working principle: When using the silent ventilator with a multi-effect filtering structure, a multi-effect filtering structure is provided, which can guide the airflow to pass through the primary filter 4, the activated carbon filter 6 and the ozone filter 7 in sequence for multiple filtrations. A noise reduction and silent structure is provided, which can reduce vibration noise and isolate noise in conjunction with the sound insulation board 12, making the ventilator noise-reducing and silent, thereby increasing the overall practicality.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
