Description

Schedule Scheduler

Object of the invention

The present invention relates to a time programmer, intended to control the start-up and stopping one or more electrical devices by connecting or disconnection to the supply network according to a program timer

Background of the invention

Today the use of devices is common electrical more or less automated, however many of these devices do not comprise means for said function, for example for its simplicity of design. This is how time programmers are used to power heating devices, lighting, pumps water and others on a timed basis. These time programmers mainly comprise a power connection connectable to an electrical network, a clock mechanism with a time disk and a plurality of pins of actuation of a switch and at minus a plug base for device connection electrical that you want to control.

To get a manufacturing cost under the clock mechanism is very simple, powered by the current mains power supply, each of the drive pins represents a period of time, usually 15 or 30 minutes, so that during the rotation of the hour disk, said pins go over the switch for actuation or release as these are displaced sideburns.

This switch, which is sandwiched between The power connection and the plug base usually presents simple contacts, so that they do not support large loads, although these programmers are specified with intensities nominal up to 16 amps and 3,500 watts. So, really, under high load, these switch contacts occur a voltaic arc that ends up burning them, rendering the Scheduler with the possibility of fire risk.

Description of the invention

The hourly programmer, object of this invention it presents some technical peculiarities destined to offer a safer and more efficient operation when subjected to large loads of electricity consumption.

Thus, the programmer comprises a contactor or relay with the steering terminals connected to the switch of the clock mechanism to regulate the passage of current between the power connection and the base or plug bases for electrical devices to control.

This allows to obtain two main advantages which imply greater durability and reliability of operation. First, the switch is no longer subject to the passage of the corresponding high intensity with a large load of consumption of the connected electrical devices, thereby improving their duration. Second, the contactor or relay can be chosen from those they exist in the market for a maximum of work current desired, whose internal mechanisms are surely manufactured to support the requested loads.

In a preferred embodiment it is provided that the power connection to the mains be a plug conventional to the electricity grid, so that the installation of the Schedule programmer is simple, simply connecting it between the base of the power supply network and the electrical device to Timed control.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view of an embodiment of the time programmer with front disk of control

- Figure 2 shows an elevation view of another embodiment of the time programmer with side disc of control.

- Figure 3 shows a block diagram

Preferred Embodiment of the Invention

As can be seen in the figures referenced the time programmer comprises in a housing (1) a power connection (2), in this case a plug to a mains base thus represented in figure 1, and a plug base (3) to support the connection of devices and devices electrical to be connected in a timed way, also being housed in said housing (1) a clock mechanism (4) and a contactor (5) or electrical relay.

The clock mechanism (4) is powered by the lead wires (21) of the connection terminal (2) for functioning. This clock mechanism (4) has a disc schedule (41) in which there are a plurality pins (42) scrollable, corresponding to consecutive portions of time. These pins (42) are faced with a switch (43) of the clock mechanism (4), so that according to its operational position or inoperative, switch contacts close or open (43). This switch (43) is connected to the government (51) of the contactor (5), which in turn presents the terminals of interruption arranged between the lead wires (21) of the connection terminal (2) and lead wires (31) of the base plug (3), enabling or disabling the power supply of electrical current to electrical devices connected to said plug base (3).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.

Claims (2)
