Abstract
A fresh air ventilator with a pressure detecting device belongs to the design and manufacture technical field of indoor air ventilating devices, and adopts the scheme that an air supply fan is arranged at an outdoor air supply opening; an exhaust fan is arranged at an indoor air exhaust opening; and an anion generator, a filter, a sterilizing lamp and a differential pressure detecting device are arranged on the device. The pressure detecting device is mounted on a wall, and the air supply opening, the air exhaust opening and a ventilating pipe are used to communicate the indoor with the outdoor. The indoor air feels foul enough to require ventilation, the air supply fan is started to enable the fresh outdoor air to enter the housing by passing an in-flow opening, the filter and the sterilizing lamp, and undergo ionization and heat exchange so as to change the indoor-entering air to be fresh and suitable; and the exhaust fan is started to exhaust the indoor air from the air exhaust opening to the outdoor. An electric draught deflector serves the function of preventing the outdoor cold air from entering the indoor, the indoor heat from being lost, and the fan parts from being damaged. A pressure sensor and the differential pressure detecting device are used to detect the pressure at the air inlet at all times, so as to clean timely the sediment on a filter screen. And the problems of the prior art are solved.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of indoor air changing device.
Background technology
The indoor-outdoor air air interchanger that uses in people's life at present, air hole formula and ventilation fan formula etc. are arranged, the air suction inlet of its device and outlet all are open state, like this will the generation chamber outer reverse intrusion of high wind, and this reverse intrusion can cause damage to fan and various filter.Outdoor on the other hand unholiness air also can pollute room air by in the opening port inlet chamber.In addition, the apparatus structure complexity that also has all bothers for care and maintenance very much.Especially the function singleness of these kinds device can only play gas exchange action.Therefore say that existing air interchanger is not very desirable.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of multi-functional, safety and environmental protection and maintenance fresh air ventilator easily in the use, with solve existing product problem.
Structure of the present utility model is as shown in drawings: partly be made of ventilation fan part, heater section and filter.One side has a room air inflow entrance on the top of ventilation fan housing.Side at the room air inflow entrance has an outdoor air air supply opening.On ventilation fan lower housing portion one side, have the outdoor air inflow entrance.On a side of outdoor air inflow entrance, an indoor air discharge port is arranged.One exhaust outlet draught-deflector is arranged in indoor air discharge port.One cross next door is arranged in the ventilation fan housing.Pars intermedia in the cross next door has a heat exchanger.On heat exchanger, have return air filter.One air supply fan is arranged on the outdoor air air supply opening.In the bottom of air supply fan one anion generator is arranged.One exhaust fan is arranged on indoor air discharge port.On the top of heater housing one air supply opening is arranged.In the heater housing, have heater.On heater top one excessive temperature sensor is arranged.In heater housing bottom one air inlet is arranged.One air supply pipe is arranged between air inlet and the outdoor air induction port.One filter exhaust outlet is arranged on the top of filter housings.In the filter housings bottom one filtering air inlet is arranged.One air inlet draught-deflector is arranged in filtering air inlet.Between filter exhaust outlet and outdoor air inflow entrance, a ventilation duct is arranged.Bottom in filter housings has filter No. one time.Top at following filter has aflter-fillter.One sterilamp is arranged between two filters.One pressure test device is arranged at the top in housing is cried in filtration.On the front of pressure test device, have the positive pressure inductor.On the back side of pressure test device, have the backside pressure inductor.Use of the present utility model is that it is installed on the body of wall, by outdoor air inflow entrance, outdoor air air supply opening, room air inflow entrance and indoor air discharge port and ventilation duct indoor and outdoor is linked.When the dirt of room air sensation, when needing ventilation, start air supply fan, electronic draught-deflector is opened, the outdoor air inflow entrance produces negative pressure, and outdoor fresh air enters in the housing through filter screen and bactericidal lamp with inflow entrance, again in the over-heat-exchanger inlet chamber, by anion generator ionization was carried out in air inlet before in inlet chamber, produced anion.Air in the inlet chamber after filtration, after sterilization, heat exchange and the ionization, in the inlet chamber, make room air keep fresh.Start exhaust fan simultaneously, make the room air inflow entrance produce negative pressure, room air drains into outdoor behind return air filter and heat exchanger from indoor air discharge port.On filtering air inlet and room air outlet, all have electronic draught-deflector.Playing the effect of running off with the room air heat in the outdoor cold air inlet chamber that stops at ordinary times.The effect that also play and prevent the reverse intrusion of outdoor high wind, damages fan part.Pressure inductor and pressure detector are to be used for detecting constantly air intlet pressure, so that the timely online deposit of cleaning and filtering.
Of the present utility model simple in structure, owing to have filter, sterilamp, heat exchanger and anion generator, can be the indoor live gas that hygienic environment-protecting is provided.Solved the problem that existing air interchanger exists.
