Abstract

The utility model provides an electronic control switched tee joint. The electronic control switched tee joint is characterized by being provided with a flow distribution chamber, wherein one end face of the flow distribution chamber is provided with an air inlet, and the other end face of the flow distribution chamber opposite to the air inlet position is provided with two air outlets. An air valve plate and a rotary shaft arranged between the two air outlets are arranged in the flow distribution chamber in a pivoting mode, and when the air valve plate rotates around the rotary shaft and then abuts against two side walls of the flow distribution chamber respectively, the air inlet is communicated with a channel of one air outlet, and meanwhile the air inlet is not communicated with a channel of the other air outlet. The rotary shaft is connected onto an output shaft of a synchronous motor. Due to the fact that the rotatable air valve plate is arranged between the air inlet and the two air outlet to achieve control of the air flowing direction, the electronic control switched tee joint is simple in structure, the air channels are not required to be turned, the operation is reliable, and a space is further reserved for further combination.

Description

A kind of threeway of automatically controlled conversion

Technical field

The utility model belongs to a kind of ventilation equipment, relates in particular to the ventilation ventilation threeway of using in a kind of bathroom.

Background technology

The ventilation unit of bathroom ventilating and exhausting device is to send into outside air indoor and get rid of water vapour in the bathroom.Existing big air quantity low noise main frame is a single functional product: under heavy-duty motor drove, wind wheel transported out the wind that sucks by airduct.Can be used for blowing or ventilation usefulness, it is simple and reliable to have function, and no rapid wear accessory such as is excused from a college course all the year round at advantage.Similar products also have single-pass, bilateral and threeway product etc.It adopts a kind of rotatable air channel to control the air-out position, to realize the air-supply function of diverse location.There is accessory precision prescribed height, fragile, the characteristics that reliability is not high.

The utility model content

The utility model provides a kind of threeway of automatically controlled conversion, its objective is to solve the shortcoming that prior art exists, and makes the bathroom ventilating system more reliable, and uses flexibly.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of threeway of automatically controlled conversion is characterized in that: have a diffluence room, an end face of diffluence room is provided with an air inlet, and diffluence room's another end face relative with the air inlet position is provided with two air outlets; An air door plate is located at two rotating shafts between the air outlet with one and is hubbed in the diffluence room, after air door plate rotates around the axis during respectively with two sidewall contacts of diffluence room, respectively with the channel connection of air inlet and an air outlet and the passage partition of air inlet and another air outlet simultaneously; Rotating shaft is connected on the output shaft of a synchronous motor.

Diffluence room is provided with two limit switches, and air door plate is during respectively with two sidewall contacts of diffluence room, the limiting plate contact limit switch of establishing in the rotating shaft, and limit switch is connected with controller, and synchronous motor is also controlled in the controller connection.

Usefulness of the present utility model is:

The utility model is owing to be provided with rotating air door plate to realize the control to the flow direction of wind between air inlet and two air outlets, simple in structure, air channel itself need not rotation, thus reliable, and be further to make up leaving space.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is a kind of threeway that is applied to bathroom ventilation usefulness, has a diffluence room 1, and so-called diffluence room 1 is a seal chamber, and its cross section is near trapezoidal.Relatively shorter end face in diffluence room 1 is provided with an air inlet 20, and this air inlet 20 is connected by air intake passage with big air quantity air-supply main frame.Diffluence room 1 another end face relative with air inlet 20 positions (also namely long that end face) is provided with two

air outlets

21,22, two

air outlets

21,22 can be communicated with bathroom space by wind pipe.

Diffluence room 1 below is provided with a synchronous motor 3, be connected with a rotating shaft 51 on the output shaft of synchronous motor 3, the position of rotating shaft 51 is positioned at diffluence room 1 and is positioned at two

air outlets

21,22 centre, connecting an air door plate 5 in the rotating shaft 51, also is that air door plate 5 also is the air door centre of gyration with rotating shaft 51() be hubbed in the diffluence room 1.

Be provided with two

limit switches

41,42 in the diffluence room 1.

Air door plate 5 around the shaft 51 when rotating sidewall 12 contacts of back and diffluence room 1 (as Fig. 2, Fig. 4), the channel connection of air inlet 20 and an air outlet 21 and the passage of while air inlet 20 and another air outlet 22 can be cut off, at this moment air door plate 5(air door plate 5 is simultaneously also as the limiting plate of synchronous motor 3) can contact limit switch 42, limit switch 42 is issued the controller (not shown) with signal, the power supply of synchronous motor 3 is cut off in controller control, make synchronous motor 3 stalls, synchronous motor 3 output shaft stop further rotation, also be that air door plate 5 can further not rotate, just be parked on the corresponding position, thereby a commutation that realizes air door plate 5 is moved.At this moment, charge air flow flows out from air outlet 21 after entering diffluence room 1 by air inlet 20 again.

Air door plate 5 is around the shaft 51 when rotating sidewall 11 contacts of back contact diffluence room 1, the channel connection of air inlet 20 and an air outlet 22 and the passage of while air inlet 20 and another air outlet 21 can be cut off, at this moment air door plate 5 can contact limit switch 41, limit switch 41 is issued controller with signal, the power supply of synchronous motor 3 is cut off in controller control, make synchronous motor 3 stalls, synchronous motor 3 output shaft stop further rotation, also be that air door plate 5 can further not rotate, just be parked on the corresponding position, thereby a commutation that realizes air door plate 5 is moved.At this moment, charge air flow flows out from air outlet 22 after entering diffluence room 1 by air inlet 20 again.
