DE19513996A1 - Switch-on of heating thermostat after time-limited ventilation of room - Google Patents

Abstract

The thermostat is switched off and on by means of pushbuttons (5,6) to control the flow of hot water through a valve (24) operated by a cone (20) and plunger (22). The valve is closed while a window or door is left open for a selected duration, the expiry of which is signalled by a timing board (17) with a miniature battery (15) and rotary plate switch (18). The time is indicated by a pointer on a scale (19), and an audible signal is emitted until the "on" pushbutton (6) is operated. The sensitive element of the thermostat may be protected from cold air by a removable cap.

Description

The invention relates to one with two options types equipped with signaling direction for a temporary shutdown of a Radiator thermostats to avoid energy loss and costs used for window and door ventilation becomes.

Currently, and especially for convenience, the radiator thermostat is mainly used for room ventilation not turned back and thus energy costs through the one flowing cold air wasted even more insofar as the window or door z. B. by oblivion or wrong Time calculation only closed after opening time is too long becomes. Only the well-known installation of window contacts elements with power supply and additional device automatic closing of the thermostat and thus the heating water supply during ventilation. As a result of the assembly-intensive and accordingly associated with not insignificant costs These facilities are only isolated and fitted mainly in public buildings (schools, sick houses etc.) installed. (No time control by signaling.)

The invention has therefore set itself the task of all common due to uncontrolled room ventilation to avoid upcoming energy losses and looks like to claim 1 in a first execution, the off / on Switching the radiator thermostat by installing one on the  Pin actuating cone of the sensor element to be pressed on Slide rod in front. At the same time, the for the Initiation of this process required actuation of a Insert button for the sequence of the currently set clock time (make setting only when time changes) acti fourth and signaled with a chime. The shutdown of the signal and the release of the blocked valve takes place by pressing the push-back button (counter switch).

In a second version, the one in claim 1 specified invention the penetration of cold air on the Thermostat sensor - but with the radiator not switched off thermostat - just by sliding one with one Insulating insert provided hood-shaped cover ge protects. The one that can be set here and for several times The duration of the ventilation time to be selected is long fed from a button cell (small battery) and with a turntable switch controlled timer. After acceptance the cover, which is screwed on to the Timer element stands (union to an isolating / signal cap), the chime is in the time switch part as well also the insulation of the relevant sensor is removed.

The advantages achieved with the invention result in in summary, contrasting the current ventilation proceed as follows:

• - No turning back of the thermostat and screwing back into the old operating position, but convenient and immediate Intermediate parking or insulation of the sensor element just pressing a button or picking up / taking off the signal and Protective cover;
• - Selectable setting of the duration of the thermostat shutdown or opening time of the window, door u. Like. by minutes precise acoustic signal specification;
• - saving energy costs and promoting environmental protection, since previous non-shutdown of thermostats, and esp especially with long ventilation times due to forgotten  Window closure u. Like., could be avoided in the future;
• - Saving energy costs also insofar as. B. a Heated radiator in the current procedure due to too long room ventilation time - due to lack of time control etc. - for a re-heating one accordingly higher effort required;
• - Possibility of using the insulating cover even when not adjustable or not in use heating body (e.g. warm season) to only stay here for a time to have control over a certain ventilation time, whereby then the coverage for signaling also on windows grabbed u. Like. Can be put on, and finally
• - General suggestion for more room ventilation through the now Comfortable switching on / off of the heating thermostat or sensor with simultaneous ventilation time monitoring through adjustable signaling.

In order to be able to influence the sensor of the thermostat even without the previously dependent control of the supply of the cold or warm air into the corrugated sheet element 25 filled with steam in the exemplary embodiment (for example with a liquid sensor) for a time-limited room ventilation, he sees the invention as a mechanical intervention within of the thermostat body. For this purpose, according to FIG. 3, which shows an enlargement to FIG. 1 (overall overview in the form of a detail) and a principle representation of this procedure - also based on FIG. 4 and for further explanation with FIG. 5/6 - in the area the lower thermostat housing 1 a pressure-exerting device for influencing the pin actuating cone 20 installed.

So that the device can be operated as stress-free as possible, a separation of the spring pressure located in the area of the Wellblechele element with the control starting from here on the pin actuating cone 20 through an interface in the cone neck 21 in the form of a stepped bolt 12 and socket bolt 13 is provided. This measure according to the invention is regarded as a precautionary measure and could possibly also be omitted, also with a view to a different thermostat design (e.g. thermostatic element with liquid sensor).

The mechanical and manually operated device consists of a guide channel 2 in which the slide rod 3 is present. The sleeve-shaped guide channel 2 in the form of a rectangle is connected according to FIG. 3 (side view) and FIG. 4 (top view) at its ends with the thermostat housing 1 , with cone 20 being carried out in a vertical position in the housing in the central region of the pin actuation.

The slide rod 3 has a cutout 4 , which is formed with an insert shape 7 and a push-back shape 8 . The ends of the slide rod 3 are each formed into an insert button 5 and push-back button 6 , so that the requirements for a back and forth movement of the slide 3 are given. For the production and transmission of signals to the timer board, a double current contact 9 and an insertion contact 10 are arranged on the upper wall of the guide channel 2 and 3 in the upper region of the slide rod. The connection or separation of both contact points is brought about via an existing guide slot 11 in the guide channel by the respective directional movement of the slide rod 3 in the representation of FIGS. 3/4 and 5/6 (see also the following explanation).

To the elimination of the radiator thermostat to allow tilverschluß by Ven and thus to make the penetrated by cold air ineffective on the sensor at a room ventilation, the slide bar 3 according to Fig. Depressed 3/4 with a sliding lever handle 5 in the direction of arrow against the Thermostatge housing. The slide-in shape 7 slides onto the pin actuating cone 20 , which then presses on the pressure pin 22 , closes the valve in the valve housing 24 via the stuffing box 23 and throttles the heating water supply to the radiator. This state of affairs can be seen from FIGS . 5/6, it also being apparent at the same time that the insertion contact 10 is inserted into the switching area of the double current contact 9 and thus also a bridge connection with the two contact halves for the signaling process in the timer board 17 in FIG. 1 has been produced. Further, FIG. 5, the ply separation of the eingetre tene compared to FIG. 3 in the rest position located step-and-socket bolts 12, 13.

After the room ventilation is to be ended after the specified time and by signaling an alarm tone, the slide rod 3 is brought into the rest position and the thermostatic valve is opened again as far as the thermostat sensor controlled at that time by the corrugated iron element permits. This process is carried out only by pressing the push-back button 6 to FIGS . 5 and 6 (direction of arrow), the push-back formation 8 of the slide rod 3 likewise assuming its starting position according to FIGS. 3 and 4 and the stroke lock of the expressed pin actuating cone 20 is raised by the insert molding 7 . Furthermore, the connection of the double current contact 9 is inevitably switched off by the insertion of the plug-in contact 10 and the signaling (eg alarm tone). Labeling of the push-in and push-back buttons 5 , 6 is not necessary insofar as only the button pushed out of the thermostat housing 1 can be operated in each case.

The signaling device is arranged according to the representation of FIGS. 1 and 2 on the head part of the radiator thermostat. It consists of a clampable cover, the A position 14 , in which the button cell (small battery) 15 is housed as a power source, and from the receiving chamber 16 for the storage of the timer board 17 , which is in connection with the turntable switch 18 . The connecting wires to be inserted from the timer element to the double current contact 9 could e.g. B. next to the inner wall of the adjusting handle 26 of the thermostat body or in the region of the pin actuation supply cone 20 (depending on the type of execution of the radiator thermostat and the like.).

The time setting for the start of the signaling is carried out with a turntable switch 18 , the selectable time segments for the duration of the room ventilation up to 15 minutes being shown on the scale display 19 , which is located on the outer wall of the receiving chamber 16 of the timer board 17 are. The signaling, e.g. B. in the form of the intervals of an alarm tone, remains until you press the push-back button 6 (cancellation of the bridge connection on the contacts 9/10 ). Switch position "P" is used to check the button cell for operational function.

In a second embodiment, throttling the supply of cold air to the sensor element during room ventilation and signaling the end of the duration of the ventilation time to be selected, is dealt with in a further embodiment with FIGS. 12-21.

The invention relates here to an insulation to be produced of a sensor element of every embodiment, specifically on the basis of a covering method in which the sensor system concerned is protected against external temperature influences by fitting a hood-shaped cap ( FIG. 11). The device to be designated according to its task as an insulating / signal cap is composed of the timer element 32 and the cover 34-36 to be inserted with it in a screw connection and manufactured in various sizes and shapes. Come in the embodiment

• - The cover 34 for a thermostat with a built-in sensor ( Fig. 7 and 8),
• - The cover 35 for a remote sensor housing ( Fig. 9) and
• - The overlap 36 for a remote setting element ( Fig. 10)

into consideration. The advantage of the overlap with the timer element (for example 34 with 32 in FIG. 17) which is to be connected via screw threads 33 , 38 is advantageous in that, among other things, the production is made simpler and less expensive, and sales and warehousing are more customer-friendly and clearer can be processed (exchange of overlaps possible, possible replacement replacement cheaper, etc.).

The timer element 32 shown in FIG. 12 in the side view and in FIGS . 13/14 on the switch and thread side has the same basic technical features as the built-in radiator thermostat. Only in addition to the insert 27 for the button cell 15 , the receiving chamber 28 for the timer board 29 and the turntable switch 18 with scale display 19 , the timer push pin 30 with push pin disk 31 and return spring 39 have been added for the signal to be switched.

The impetus for signal preparation, based on Fig. 17, is initiated by inserting the cap on the sensor element and in transmission of the push pin 30 on the timer board 29 .

The coverage z. B. 34 , with the inner view of FIG. 16, is provided in the inner wall part with an insulating insert 37 . The insert can - according to their intended use - consist of different materials, eg. B. from a bristle hair lining, e.g. T. and sectionally long-haired and conformable, especially to protect the opening part of the cover 34-36 from sealing against the ingress of cold air. Fig. 17 shows e.g. B., a radiator thermostat based on Fig. 7, which is provided with a signal / insulating cap (timer element 32 and cover 34 ). In the cutout it is recognizable that the area of the insulating insert 37 extends to the outer edge of the cover 34 , adjacent to the valve housing 24 .

FIG. 18 shows the overlap 35 which, with the interior view of FIG. 19, has a rectangular initial shape and is used for the insulation of the remote sensor housing according to FIG. 9. Since in this embodiment the sensor area is located directly in the wall area, the outer border of the cover 35 is also provided with a slightly raised bead-like insulating insert 37 .

The cover 36 , shown in FIG. 20, is adapted to the external dimensions of the remote setting element ( FIG. 10), with the outer closure here also being formed with a stronger insulating pad 37 according to the internal view of FIG. 21.

In summary, there is room ventilation with both Embodiments of the device for switching off / on or Insulation of radiator thermostats and. Like the following Operating method:

• a) Switching the radiator thermostat on and off. the like
