Description

TECHNICAL FIELD

[0001] The utility model relates to a ventilation device technical field, concretely is a kind of air conditioning ventilation device with circulating purification function. BACKGROUND

[0002] Air conditioning ventilation device is a kind of equipment for adjusting indoor air temperature, humidity and quality. It keeps the comfort of environment by introducing fresh air, discharging indoor dirty air and cooling or heating air. The device usually includes fan, filter screen, heat exchanger and other core components, fan filters air through filter screen, removes dust and particulate matter, and then cools or heats air through heat exchanger to adjust indoor temperature. Air conditioning ventilation device not only can effectively control indoor temperature, but also has ventilation function to ensure the circulation of indoor air and the supply of fresh air, and some modern devices also integrate dehumidification, humidification, purification and other functions to improve air quality and improve the comfort of living or working environment.

[0003] Air conditioning ventilation device can circulate and purify air, and the air inlet pipeline of air conditioning ventilation device is provided with filter, mainly to filter dust, pollen, bacteria and other particulate matters in the air entering indoor to maintain air cleanliness. However, as the time of air conditioning ventilation device circulating and purifying air increases, filter will gradually accumulate a large amount of dust and impurities, resulting in reduced filtering effect and airflow obstruction, which further affects the operating efficiency of air conditioner and indoor air quality. Therefore, filter needs to be replaced regularly to ensure that ventilation device can work normally and maintain the cleanliness of indoor environment. However, users are difficult to detect the timing of replacing filter, mainly for the following reasons. First, the clogging process of filter is slow, and the reduction of air flow or the decline of air quality will not immediately appear. Secondly, air conditioning equipment has no obvious change in appearance, unless the equipment emits abnormal noise or the refrigeration effect is significantly reduced, otherwise users usually do not notice the problem. Finally, users lack knowledge of filter maintenance period, especially if air conditioner is not equipped with reminder function or device to display filter status. Due to these factors, customers are difficult to determine the best timing of replacing filter. Failure to replace filter in time will result in reduced air conditioner efficiency, increased energy consumption, poor air quality and shortened equipment life.

[0004] In view of this, we propose an air conditioning ventilation device with circulating purification function. UTILITY MODEL CONTENTS
