Definitions
- the invention relates to a control of a gas-powered heater according to the preamble of the first claim.
- thermoelectric In the field of commercial kitchen technology, two or more preparation areas are often regulated separately in one application. This means that there are several gas valves, each equipped with thermoelectric
- the present invention is based on the problem of developing a universally usable regulation for a gas-operated heating device with more than one burner, in which commissioning, regulation and shutdown is made possible.
- Each burner should be independently controlled, on and off can be turned off.
- the construction and manufacture of the device should be as simple and inexpensive as possible.
- the problem is solved in that two valves are connected to one another in a gas-tight manner.
- the first valve has an ignition lock that closes the main gas flow when igniting, a thermoelectric ignition fuse, a thermostat and optionally an integrated pressure regulator.
- the commissioning of the first valve enables the gas flow to be switched on and off and optionally has an integrated piezo igniter or alternatively a switch for activating an electrical igniter.
- the first valve has two gas outlets, a first gas outlet for connecting the second valve, which is located downstream of the
- Thermostats a second gas outlet downstream of the thermostat that leads to the first burner.
- the second valve is a thermostat.
- the first output of the first valve is connected to the input of the second valve.
- the output of the second valve is connected to the second burner.
- the solution is characterized by its simple structure and its simple mode of operation.
- Fig. 1 shows a first valve of the device according to the invention in the ignition position.
- Fig. 1a shows a first valve of the device according to the invention in the
- Fig. 2 shows the first valve of the device according to the invention from Fig. 1 in
- Fig. 3 shows the first valve of the device according to the invention from Fig. 1 in the
- FIG. 4 shows a first valve of the device according to the invention in the ignition position.
- FIG. 5 shows the first valve of the device according to the invention from FIG. 4 in
- Fig. 6 shows the first valve of the device according to the invention from Fig. 4 in the
- the exemplary first valve of the device according to the invention shown in FIGS. 1, 1a, 2 and 3 is a switching and control device, which is preferably intended for a gas-operated heating device or the like. It enables the operation and monitoring of a first burner, pressure control, as well the setting and regulation of the desired temperature by controlling the amount of gas flowing to the burner.
- the first valve (1) consists of a lower housing part (3) and upper housing part (4), which has a gas inlet (5), a first gas outlet (6), a second gas outlet (7) and an ignition gas outlet (10).
- the following functional units are accommodated in the housing (3; 4) in the direction of flow of the gas:
- Thermostat 1 (19) consisting of temperature sensor 1 (37),
- Temperature adjuster 1 (23) for regulating the amount of gas flowing to burner 1 (26).
- the exemplary second valve of the device according to the invention shown in FIG. 2 includes a thermostat. It enables the desired temperature to be set and regulated on the second burner by controlling the amount of gas flowing to the second burner.
- the second valve (2) consists of a housing (25), a gas inlet (8) and a gas outlet (9).
- a thermostat 2 (20) consisting of a temperature sensor 2 is arranged in the housing (25) in the direction of flow of the gas (38), snap switch 2 (36), valve closing body 2 (22) and temperature adjuster (24) for regulating the amount of gas flowing to burner 2 (27).
- Valve 1 (1) and valve 2 (2) are connected to one another in a gastight manner by a pipeline (28).
- the gas outlet 1 (6) of the valve 1 is connected to the gas inlet (8) of the valve 2.
- the burners 1 (26) and burner 2 (27) are connected gas-tight by pipes, whereby burner 1 (26) with the gas outlet 2 (7) of the valve 1 and the burner 2 (27) with the gas outlet (9) of the valve 2 connected.
- the pilot gas outlet (10) of valve 1 is used to connect the pilot burner (29).
- thermocouple (30) Connection thread of the ignition fuse magnet (13) attached in an electrically conductive manner.
- the device according to the invention is connected to the gas network via the gas inlet (5) of valve 1.
- the device is started up via valve 1. First, the pilot flame of the pilot burner (29) is lit.
- the standby position shown in FIG. 1 a can be set, in which the pilot flame is lit but no gas flow to the first burner (26) and the second valve (2) is released by the ignition lock (11). This enables the user to quickly commission the
- the liquid-filled temperature sensor 1 (37) is positioned at an optimal distance from the medium to be controlled so that the desired temperature preset via temperature adjuster 1 (23) can be reached and kept constant. If necessary, the second burner (27) can also be put into operation.
- a desired temperature is preset with the temperature adjuster 2 (24) of the valve 2 (2) and the
- Valve closing body 2 brought into a control position, whereby the gas from the gas outlet 1 (6) of the valve 1 through the connection (28), a gas-tight
- valve 1 The pressure regulator (18) optionally integrated in valve 1, which compensates for gas network pressure fluctuations and realizes a stable burner pressure, has proven to be advantageous.
- Appropriate geometric design in the housings enables an approximately equal pressure drop across the two valves between the inlet (5) of the first valve (1) and the outlet of both valves (7; 9), which enables the inexpensive use of two identical burners (26; 27) enables.
- Fig. 3 shows the possible shutdown of both burners via the
- Thermocouple (30) breaks down, the ignition fuse magnet (13) falls off and the ignition fuse valve (12) closes.
- Ignition fuse magnet Alternatively, the user has the option of being in a standby position, switching on the pilot light, ignition safety magnet (13) and
- Ignition lock (11) in open position, independently of burner 1 or burner 2 or both to be switched off via the respective temperature adjuster.
- valve 1 commissioning via valve 1 with a push button and battery ignition is therefore described.
- Valve 1 of embodiment 2 differs in the construction of valve 1 of embodiment 1 by a different commissioning.
- Fig. 4 shows the changed start-up in the ignition position.
- the pilot gas outlet (10) is released to the pilot burner (29), a switch (17) is actuated, which generates a clock spark via an electrical spark generator (32) and ignites the pilot gas.
- Main valve (33) ignites the burner (s).
- thermocouple (30) is heated via the ignited pilot flame and a voltage is generated which keeps the ignition safety magnet in the open position. As shown in FIG. 5, the main valve (33) is opened when the button (31) is released.
- the gas can now in a manner comparable to that in embodiment 1 via gas outlet 1 (6) to valve 2 and thus to burner 2 and / or
- burner 1 Flow gas outlet 2 (7) to burner 1.
- the burners are ignited via the pilot burner (29), which is optimally positioned in relation to the burners.
- thermocouple (30) arranged in sufficient proximity to the pilot burner and the burners is used as
- thermocouple cools down and the thermal current breaks down.
- the ignition safety valve (12) cuts off the gas supply.
- the burner is switched on and off and the temperature is set via thermostats 1 and 2 in the same way as in application example 1.
- the device according to the invention for regulating the gas supply is of course not limited to the exemplary embodiments shown. Rather are
