DE3016632A1 - Timer-controlled thermostat valve for central heating radiator - has interfitting housings for timer and valve with associated electric motor and supply battery - Google Patents

Abstract

The thermostat valve is adjusted by an electric motor switched via a timer, the entire circuit being battery-operated. The timer and the thermostat valve are contained within separate housings (1,2) with complementary formations around all four sides of each, to allow them to be fitted together one above the other or side-by-side in either order. The electrical connection between the two housings is provided by a cable (3) or by cooperating contacts around the housing sides. The housing (1) for the thermostat valve incorporates the supply battery as well as the setting motor and has a rotary scale with two spaced switch riders (13,14) for setting the upper and lower temp. limits. The timer has a 24 hour time scale (7) with an indicator (6) for the actual time and circular switch riders (5).

Description

Thermostatic valve

The invention relates to a thermostatic valve, which by a plug-on Timer, according to a preselected time, electromotive on a preselected one Temperature value. is adjusted, a battery being used as the voltage source and the timer, depending on the free space on the radiator, form-fit to each of the 1; Sides of the thermostatic valve can be attached.

Such thermostatic valves are provided per radiator and can so that each room can be heated individually.

It is known that the temperature in each room is through Thermostatic valves that are adjusted by a motor (patent registration P 3005 316.8), regulated will. D.H. Individual heating of individual rooms has already been proposed.

The temperature control with thermostatic valves by a timer influenced, motor-driven changes are optimal, but the previous suggestion has the disadvantage that it is because the switching disk of the timer is concentric around the valve handle. is arranged, is very large in size. This disadvantage % Wirt that this thermostatic valve can not be attached to radiators, whose radiator niche is very narrow.

The invention is based on the object of a thermostatic valve create, which includes all the advantages of the proposal (P o o5 316.8), but can also be mounted on any radiator, even in very tight spaces.

The installation of radiators in radiator niches or ticks sometimes leaves very little space left for the thermostatic valve, so that the previously known Motorized adjustable thermostatic valve is not possible with a timer.

The object is achieved according to the invention in that the timer, which controls the motor for adjusting the valve accordingly, pluggable as required can be plugged into the thermostat valve housing on all 4 sides.

The advantages of the invention are that Ie according to space on the radiator the voluminous timer, there on the thermostat valve housing can be attached where there is still space.

Another advantage is that this is used to set the timer can be removed from the thermostat valve housing.

An exemplary embodiment of the invention is shown in the drawings and is described in more detail below: Fig. 1 shows the complete thermostatic valve with timer.

In the housing (1) is the small motor with gearbox for adjusting the Thermostatic valve, as well as the battery housed. With tabs (13) and (14) the respective upper or lower temperature is preselected. The actual thermos Tatventil housing (1) is kept as small as possible. The timer that the Motor gives the commands at which time the valve should be adjusted by motor, is housed in a separate housing (2). Through a line (3) are the electrical components iii both housings connected to each other.

The hands (6) of the timer show the current time (hours) on and the numbers (7) form the dial. The adjustable ladder are like known to be arranged in a circle.

The contacts (4) can also electrically connect the housings (1) and (2), as a result, the line (3) can be omitted.

Depending on the space available on the radiator, the housing (1) on all 4 sides (8, 10, 11 and 12) the timer in the housing (2) form-fit be plugged in here through the dovetail connection (9) It lies naturally Also close to integrating the timer on one of the 4 sides in the housing (1).

The time switch can either be a rotatable switching disk, as is known with switch tabs, or it is equipped with a so-called standing basket, i.e. the tabs are always in the same place.
