Abstract

A fan for creating a microclimate at any point in the desk area of a user. Positioned under a desk top, the fan comprises a fan and a device for moving the fan beyond the edge of the desk top, enabling adjustment of the spatial position of the fan. The technical result consists of reducing the distance between the fan and the user, enabling the fan to alter the microclimate in the desk area, at any point in the space immediately around the user, without disturbing the user.

Description

Fan.

The invention relates to domestic fans and can be used to move air at the table at home, offices, catering, educational institutions.

Known desktop fans, in particular, fanless fan with a ring equipped with nozzles, DAYSON AM01, www. technopark.ru.

The disadvantages of desktop fans, with a ring or with open blades, are that:

- the fan occupies part of the table top and interferes with the location of other objects of use, for example, cutlery, dishes, etc., writing utensils, a computer, documents, business papers, etc., and thereby interferes with the user, especially if at the table, for example, in places of public catering, four places of use and four fans are required;

- the fan adversely affects the flow of air to other objects located on the table top between the fan and the user, and can blow the air stream, for example, unstable flower vase or, for example, business papers, blow small objects off the table top, and this interferes to the user;

- the distance from the fan to the user is ~ 700 mm, therefore, to overcome this distance with an air flow, a fan of increased power, dimensions and air flow with a blade diameter of more than 200 mm is required;

- the air flow from the fan is directed only to the upper body of the user, since the table top is located in the path of the air flow.

The advantage of desktop fans is that with a variety of user needs, including changing the user's position at the table, with different physical conditions and users' clothes, the fans have four options for changing the microclimate by the direction of air flow to all points of the local space of the user's upper body:

- a change in the position of the fan on the countertop;

- rotation of the fan in a horizontal plane;

- rotation in the form of fan tilts in a vertical plane; - a change in the speed of rotation of the blades.

Known air distribution device for the desktop, containing air distributors located under the countertop tables and dividing the supply air into flows directed to the local area, that is, to the local user space, patent RU 2497048.

The disadvantage is that the device does not have the ability to change the microclimate created by it, which is unacceptable for the variety of users' needs, and also that the air flow reaches only the lower part of the user's body.

The advantage is that the device does not occupy part of the table top, the air flow does not affect objects located on the table top, the device does not interfere with the user by its location.

The closest technical solution for the capabilities of the fan is a manual mini fan, for example, a USB Portable fan, see www.cena.rn.

The disadvantages of the fan are that the manual fan is a personal use item and after application it needs to be put somewhere, for example, on the table top or in a bag, which interferes with the user, and also that it is possible to equip tables with manual fans in places, for example, public catering for general use is impossible, since the fans will be located on the table top and interfere with users, while there is a great possibility of theft of the fan.

The problem to which the invention is directed, is as follows.

Well-known household fans and ventilation systems in terms of the diversity of user needs can be divided into two groups:

- having significant potential for changing the microclimate, for example, a table fan - four possibilities, but at the same time it interferes with the user by its location on the table top, the impact of air flow on objects located on the table top is located at a considerable distance from the user, which requires an increase in power and the dimensions of the fan, directs the air flow only to the upper body of the user;

- climate changes that do not have significant capabilities, for example, an analogue of RU 2497048 - without capabilities, but they do not occupy part of the table top, air flow does not affect objects located on the table top, the device does not interfere with the user by its location.

Thus, the specific task is to develop a fan located at a minimum distance from a user with minimum power, with sufficient microclimate changes for the diverse needs of users with the ability to direct air flow to all points of the user's local space, but without interfering with the user by its location on the table top and the impact of the air flow on objects located on the table top.

The technical result that can be achieved by solving the problem is to reduce the distance from the fan to the user with the creation of the fan's ability to change the microclimate at the table at all points of the user's local space without creating interference to the user.

The specified technical result is achieved by the fact that in the known fan for creating a microclimate at the user's table, the peculiarity is that the fan is located under the table top, equipped with a device for moving the fan beyond the edge of the table top with the possibility of changing the position of the fan in space.

In addition, the device for moving the fan beyond the edge of the tabletop is made in the form of a lever with the possibility of rotation in the vertical plane around the horizontal axis, the lever is connected to the fan with the axis of rotation of the fan perpendicular to the horizontal axis.

In addition, the device is equipped with a latch for one extreme position of the fan in the form of a spring latch.

In addition, the device is equipped with clamps of any position of the fan around the horizontal axis in the form of a friction washer, two anti-friction washers and a compression spring between them, and around the axis of rotation perpendicular to the horizontal axis in the form of a friction washer, axis with a threaded section, nuts and locknuts.

In addition, the device for moving the fan beyond the edge of the tabletop is made in the form of a cylindrical slider with the possibility of reciprocating motion and rotation around its axis, the slider is located in the guide and is connected to the fan by the axis of rotation perpendicular to the axis of the cylindrical slider.

In addition, the device is made without fixing the position of the fan.

In addition, the device is equipped with clamps for any fan position during reciprocating movement and rotation around the axis of the cylindrical slider in the form of a friction radial clamp, a screw and a lock nut, and around the axis of rotation perpendicular to the axis of the cylindrical slide in the form of a friction washer, two antifriction washers and a compression spring between them. In addition, the device for moving the fan beyond the edge of the tabletop is made in the form of a bar with the possibility of rotation in a horizontal plane around the vertical axis of the bar, the bar is connected to the fan holder by the vertical axis of the holder connected to the fan by the horizontal axis of rotation of the fan.

In addition, the device is made without fixing the position of the fan.

In addition, the device is equipped with clamps of any fan position around the vertical axis of the bar and the vertical axis of the holder in the form of friction washers, nuts and locknuts, and around the horizontal axis of rotation of the fan in the holder in the form of an additional fan housing fixedly connected to two half shafts located on both sides , the axle shafts are equipped with friction washers, nuts and locknuts.

In addition, the fan is made of three high-speed.

The essential attribute “... is equipped with a fan movement device ...” is expressed in a general way, since it covers three disclosed types of movement in the execution forms: rotation in the vertical plane on the lever, reciprocating in the horizontal plane on the slider with rotation around its axis , horizontal rotation on a bar.

In this case, other types of movement of the fan beyond the edge of the tabletop along all three space coordinates with many of their mutual combinations are possible, for example, using knee-lever mechanisms, gears, Hook joints, electric drives, a flexible metal leg with an additional axis of rotation of the fan, see www.opl2.ru, a MINI USB fan for a laptop, etc., but they are more complex and larger, and as a result they achieve the same technical result indicated, that is, they move the fan beyond the edge of the table top, therefore given only as examples of sets from the general concept.

The essential sign “... is equipped with a device for moving the fan beyond the edge of the table top ...” is in causal connection with the technical result, since it reduces the distance from the fan to the user and, as a result of movement, creates the possibility for the fan to change its position in space and direct the flow air to any point in the user's local space:

- without moving beyond the edge of the tabletop, the fan directs the air flow under the tabletop similar to the closest analogue, which is not enough;

- the fan moved beyond the edge of the tabletop gets the ability to direct the air flow without interference from the tabletop to any point in the user's local space, including up, while the fan is located at a point in space - at the edge of the table - which does not deal with other objects and the user, therefore, does not interfere with the user;

- the fan moved to its original position does not interfere with the user.

The essential attribute “... with the possibility of changing the position of the fan in space” is expressed in a general way, since for each form of the essential attribute “is equipped with a device for moving the fan beyond the edge of the table top” this “... the ability to change the position of the fan ...” has features defined by the device of movement, including:

- rotation of the lever in a vertical plane around the horizontal axis creates the possibility of changing the position of the fan along the arc in the vertical plane, Fig.1, 2, 4, 5;

- the reciprocating movement of the slider with rotation around its axis creates the possibility of changing the position of the fan around the circumference, FIG. 6.7;

- rotation of the bar in the horizontal plane around the vertical axis makes it possible to change the position of the fan along the arc in the horizontal plane, Fig. 8, 9.

The essential feature “... with the possibility of changing the position of the fan in space” in all forms of execution, in conjunction with the movements of the movement device, covers the types of movements of the possible changing the position of the fan to change the direction of air flow in the local space of the user without directing the air flow to the table top, including including up, down, right, left, forward, and a combination of directions and rotations in the space between them, therefore, creates sufficient opportunities for the fan and goes in a causal connection with the technical result.

- is a solution to the problem and design intent;

- provides a specified unknown technical result;

- determines the novelty and inventive step.
