Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a fluid outlet using a fluid control element, for example, an air outlet for a near conditioner.

As shown in FIG. 1, air outlets 1 for near conditioners for home or automobiles that have been commonly used in the past include an air outlet 1 provided on the upper side of the near conditioner main body 3.
A deflecting plate 2 that deflects vertically and horizontally is provided in the air conditioner, and the deflecting plate is moved manually or automatically so that the deflected air flows uniformly to every corner of the room.

However, manual operation of the deflection plate is cumbersome and the flow is limited only in the direction of deflection.

In addition, when automatically moving the deflection plate using an electric motor or the like, having a mechanically movable part increases durability and
It has drawbacks such as noise, and the use of a motor consumes power, making it expensive.

Furthermore, in the deflected flow by the deflection plate, as the deflection angle of the deflection plate increases, the flow path resistance (pressure loss) increases, the air volume decreases, and the ability as a near conditioner also decreases.

In addition, in the case of the conventional air mix type near conditioner, the temperature distribution near the outlet becomes equal to the average depending on the degree of mixing of warm air and cold air, so it is difficult to obtain a uniform temperature distribution. It had a

The present invention proposes a fluid outlet that can eliminate the above-mentioned conventional drawbacks. In particular, the present invention proposes a fluid outlet with a structure that allows the outlet fluid to be freely deflected in a desired direction without using a deflection plate. This is a developed fluid outlet.

7b is formed with its control fluid passages 7as and 7.
On the upper side of b, a control nozzle 1 penetrating and held by the wall plate 4b is installed.
0a and 10b are provided.

Reference numeral 11 denotes a duct for passing air from the near conditioner main body, and this duct is connected to the rear opening of the fluid control element 4 through a hole. The main fluid passage 6 is blown out from the front opening 5b.

Reference numeral 18 denotes a flow path switching valve, and this flow path switching valve 18 is composed of an outer cylinder 12 and an inner cylinder 13 that is rotatably fitted tightly into the outer cylinder 12.

The structures of the inner cylinder 13 and the outer cylinder 12 are shown in FIGS. 4 and 5, and the upper surface of the inner cylinder 13 is closed with an upper lid 13a, and the peripheral surface is Through holes n t p *q are bored in three directions at intervals.

FIG. 7 shows that the switching lever 14 is in the position shown in FIG.
The figure shows the manner of each blowout flow from the front opening 5b.

That is, when the switching lever 14 is positioned as shown in FIG.
Further, the three through holes m and three through holes q are located 180 degrees apart from each other and are in a blocked state.

In this state, the pressurized fluid flows through both side walls 8a and ab, as shown in FIG.
The liquid does not adhere to the surface, resulting in a straight flow 20 with a narrow width.

This narrow straight flow 20 is obtained not only when the switching lever is rotated by 45 degrees, but also when the switching lever is rotated by 13 degrees, 225 degrees, and 315 degrees.

In this state, the pressurized fluid flows along both side walls as shown in No. 7N:.
In Figure 7, it becomes a straight flow 22 with a wider width from the mouth.

Further, since the through hole 1 is blocked, the control nozzle 10b is sealed.

In this state, the pressurized fluid flows along the side wall 8b and becomes a left wall adhesion flow (left deflection flow) 23, as shown in FIG. 7E.

In this embodiment, the flow path switching valve 18 has through holes n formed in the circumferential surface of the inner cylinder 13 in three directions at 90° intervals: left, right, and front.

Without being limited thereto, the flow path switching valve is connected to the connecting pipe 17a.
, 17b may be mutually connected or closed, or any structure may be used to allow one or both of the connecting pipes 17a and 17b to pass through to the atmosphere.

Furthermore, in this embodiment, acoustic oscillation is used to generate the left-right oscillating flow, but self-excited oscillation by other methods may also be used.
Alternatively, instead of self-excited oscillation, a separately excited oscillation mechanism that alternately opens and closes the control nozzle may be used.

Note that to change the direction of the air in the vertical direction, a vertical deflection plate may be provided at the outlet opening as in the conventional case, or a mechanism that deflects the entire air outlet in the vertical direction may be used.

As described above, according to the present invention, by connecting a flow path switching valve between the control fluid passages of a fluid control element, (a) left-right oscillating flow (proboscis left wall adhesion flow (left side deflection flow)) (1) Different types of outlet flow can be obtained, such as right-wall adhesion flow (right-side deflection flow), (ii) double-wall adhesion flow (wide straight forward flow), and (e) non-adhesive flow (narrow straight forward flow).

Also, compared to the conventional near-conditioner outlet with manual deflection, the left-right oscillating flow spreads even at the perceived wind speed.
A more uniform temperature distribution can be quickly obtained.

Further, since the present invention does not use a deflection plate, there is an advantage that a deflection flow can be obtained without reducing the air volume.

Furthermore, the present invention produces no noise compared to conventional automatic near conditioner blowing means.

Must be durable.

A right and left oscillating flow can be obtained with low power consumption.

It's also much cheaper. In the case of an air mix type near conditioner outlet, the degree of mixing of cold air and warm air becomes more uniform, so the distribution near the near conditioner outlet becomes uniform, and the indoor temperature distribution becomes uniform more quickly. It's also effective.

As described above, the present invention uses a fluid oscillator with a fluid control element at the near conditioner outlet and connects a simple flow path switching valve between the control fluid passages to obtain a desired wind direction and flow. It is useful as a fluid outlet for indoor near conditioners and automobile near conditioners.
