Definitions
- the present invention relates to a method for self-testing and checking certain functions of a cooking appliance in the form of a hot air oven, a damper or a combination of both, namely a combination damper, which a cooking chamber, which is closable with a cooking chamber door and a plurality of actuators, such as pumps, at least one heating device, at least one Beschwadungsein- direction, at least one flow generating device, such as a blower, as well as flaps and / or valves, temperature sensors and a device control.
- actuators such as pumps, at least one heating device, at least one Beschwadungsein- direction, at least one flow generating device, such as a blower, as well as flaps and / or valves, temperature sensors and a device control.
- Modern cooking appliances are very sophisticated equipment with a variety of individual components, which are due to the often occurring, inter alia, due to the high operating temperatures occurring stresses during operation are subjected to some wear, so that a variety of disturbances can occur, the desired cooking result impair or even prevent.
- the operation of the fan can be monitored by appropriate monitoring of the fan motor, for example by means of Hall sensors.
- the operation of pumps, such as the drain pump, can be monitored, for example, by pressure sensors, the measurement of the flow rate, or the measurement of the current drawn by the pump.
- the necessary sensors and controls are disadvantageous. They are not only expensive and therefore expensive, but the sensors themselves are prone to failure or failure, so that it can not be determined whether the responsible for the device function unit itself or the monitoring sensor is defective. In particular, problems may arise in customer service, especially in sparsely populated areas.
- the present invention is therefore based on the object, while avoiding further sensors for checking the operation of actuators of a cooking self-test suggest method according to their automatic sequence, whether and if so which of the actuators has a defect, so that a targeted maintenance or certain malfunctions of actuators can be determined or excluded.
- the inventive method for self-testing and checking certain functions of a cooking appliance in the form of a hot-air oven, a damper or a combination of both, namely a combination damper characterized in that by means of the temperature sensors of the cooking appliance, the operation of the actuators of the cooking appliance is checked in that the detected temperatures and temperature profiles with reference temperature values or reference temperature profiles which are to be expected during operation of the respective actuator and which are stored in the electronic device control are compared and, if the detected value matches the corresponding reference value, the function of the corresponding actuator or, in the case of a deviation of the detected value from the corresponding reference value, the malfunction of the corresponding actuator is detected and displayed by the electronic device controller, stored and / or transmitted for evaluation eginn of each acquisition, the cooking appliance is in a defined initial state.
- a basic principle of the self-test method according to the invention is the evaluation of certain temperature change rates.
- the rating depends, among other things, on the cooking appliance size, the type of energy and voltage or the type of gas. So this results in device-dependent limit values.
- the temperature measurements can thus confirm or invalidate device defects. By limiting the malfunction of the cooking appliance on individual components, especially the disposition of customer service can be significantly improved.
- At least two actuators are checked successively and that the defined initial state of the at least second actuator test is generated essentially by the preceding actuator test.
- several actuators can be checked consecutively in a self-test in a correspondingly fast sequence.
- the actuator follow-up test is not permitted if the preceding actuator test has not been performed, and the entire test procedure is aborted. This avoids false test results and avoids the risk of malfunctioning actuators being detected as defective. Furthermore, it is particularly advantageous that the climate control and / or the cleaning of the cooking appliance are checked by means of the self-test. This can be done both in different self-tests as well as in a total self-test.
- At least one of the following actuators of the cooking appliance can be checked:
- the functionality of the heater can be determined by heating the cooking chamber over a certain temperature range within a predetermined time interval.
- the functionality of the steaming in cooking appliances with direct water supply can be determined by detecting a temperature drop during active steaming after heating the cooking space to a predetermined temperature.
- the humidification test can thus immediately follow the test of the heater.
- the test can be carried out by the fact that the supply of 100 ° C hot steam can detect a temperature increase of the cold cooking space.
- the functionality of the dehumidification is determined by means of a dehumidifier that when heated cooking chamber after opening the dehumidifier, the temperature of a sensor positioned in thermal coupling with the dehumidifier, preferably a sensor in a Zu Kunststoffrohr, in a predetermined time interval by a predetermined Amount falls.
- a sensor positioned in thermal coupling with the dehumidifier preferably a sensor in a Zu Kunststoffrohr
- the oven temperature sensor if it is arranged in sufficient thermal coupling with the dehumidifier.
- Dehumidification can be achieved by supplying ambient air or else by injecting water, ie quenching the steam atmosphere.
- the functionality of the circulating pump is determined by the fact that, when the cooking chamber is heated up, after the circulating pump has been switched on, the cooking space temperature drops by a predetermined amount in a predetermined time interval. This eliminates the need to directly detect the operation of the circulation pump with corresponding sensors, as indicated above. Furthermore, it is advantageous that the operability of the drain pump is determined by the fact that at first filled liquid reservoir and active circulation pump after switching on the drain pump, the cooking appliance is heated in hot air mode and after a predetermined time interval, a temperature significantly higher than 100 ° C is detected. The connection is as follows: When the circulating pump is in operation, the cooking chamber is cooled down by the water permanently pumped through the cooking chamber.
- the temperature in the cooking chamber can not rise significantly above 100 ° C even at maximum heat output.
- This water cycle is interrupted when a functioning drain pump is switched on.
- the liquid reservoir of the circulation pump is emptied.
- the circulation pump runs empty and can not pump water into the cooking chamber. Without the water supply, the cooking chamber can now heat up to the set target temperature greater than 100 ° C.
- the door seal detects a sufficient sealing effect, characterized in that after heating the cooking chamber to a predetermined temperature after temperature drop when the heater is switched off, shut off actuators and closed door is detected.
- the present invention is not limited to the fact that a self-test method according to the invention can be tested for its functionality in operation.
- the self-test method according to the invention is also suitable according to the invention for being used for the self-test of a new device. This facilitates the final inspection of the new device before delivery to the corresponding customer.
- the first reference values stored can be calibrated.
- the determined values are stored in a value table for their later checking. Based on this table of values, any deviations that occur can be recorded accordingly.
- the inventive method can be started by a wired or wireless connection to the cooking appliance.
- the individual self-tests run essentially automatically and their result is displayed automatically and optionally transmitted as data and / or stored.
- the test can be done at night when the cooking appliance is not needed.
- the user can also be instructed to carry out the necessary preparations, for example to leave no food support in the oven at the end of use the previous day.
- the present invention also includes a cooking appliance in the form of a hot-air oven, a damper or a combination of both, namely a combi steamer, with a cooking chamber which can be closed with a cooking chamber door and a plurality of actuators, such as pumps, at least one heating device, at least one at least one flow generating device, flaps and / or valves and temperature sensors and an electronic device control, said cooking appliance is suitable and capable of performing a self-test method according to one of claims 1 to 14.
- a cooking appliance in the form of a hot-air oven, a damper or a combination of both, namely a combi steamer, with a cooking chamber which can be closed with a cooking chamber door and a plurality of actuators, such as pumps, at least one heating device, at least one at least one flow generating device, flaps and / or valves and temperature sensors and an electronic device control, said cooking appliance is suitable and capable of performing a self-test method according to one of claims 1 to 14.

- cooking appliances are also suitable for carrying out the method according to the invention, in which separate steam generation takes place outside the cooking chamber 6 and steam is introduced into the cooking chamber 6 for steaming.
- Fig. 3 is a perspective view is shown on the left side of the cooking appliance 1, with opened or removed left side wall, so that the view is free on the so-called "technical room".
- This room is located next to the device Control and other unspecified elements, because usually, an exhaust pipe 23, with the air directly from the cooking chamber 6 can be removed.

- the circulating pump serves to circulate cleaning liquid
- the drain pump 51 serves for emptying the liquid reservoir (not shown), which is located below the cooking chamber.
- the individual components of the self-test method according to the invention will be described below.
- the starting point of such a self-test method is the defined initial state of the cooking appliance from which the self-test procedure is started.
- the self-test method is characterized in particular by the fact that temperature measurements can be carried out by the temperature sensors installed in the cooking appliance, as a result of which certain actuators can be tested for their functions.
- a basic principle of the self-test method according to the invention is the evaluation of certain temperature change rates.
- FIGS. 19 and 20 in which graphically time-dependent temperature profiles are shown in idealized form.
- Fig. 19 are three temperature curves 53, 54 and 55, wherein the temperatures are to move between a temperature Tstart and Tsoii.
- the curve 53 indicates the temperature profile with a correctly functioning heater.
- the target temperature Tsoii is reached.
- the time interval can be, for example, 60 seconds.
- the curve 54 reaches the desired setpoint temperature Tsoii only at time h, which is twice the time compared to ti, ie 120 seconds in the example. As a result, it can be stated that either one phase of the electric circuit or one radiator element has failed. If a curve follows according to curve 55, it is determined that the heating device has failed.
- Fig. 20 idealized temperature decay curves 56, 57, 58 and 59 are shown, which lead from an initial temperature value Tstart to a lower temperature value Tsoii.
- Curve 56 shows the normal temperature drop when the heating device is switched off, for example 2 Kelvin in 60 seconds. With active humidification, the curve 57 is expected, for example -10 Kelvin in 60 seconds.
- the expected temperature drop with active dehumidification is represented by curve 58, for example -15 Kelvin in 60 seconds.
- the fastest temperature drop is expected when the circulation pump is active, for example -15 Kelvin in 30 seconds according to curve 59. If, however, the drain pump is active, a normal temperature profile according to curve 56 is expected when the circulating pump is switched on. In the event of a fault, namely a defective drain pump, the temperature profile according to curve 59 would occur.
- the rating is u.a. depending on the device size, the type of energy and voltage or the type of gas. This results in device-dependent limit values.
- the temperature measurements should confirm or invalidate device defects.
- the self-test method of the present invention comprises two areas: the climate control of the cooking appliance and
- Dehumidifying device in particular supply air flap.
- the self-test method according to the invention is limited to those actuators that are not automatically checked during normal operation. These are: 1. circulating air blower: error messages, for example via CAN bus;
- Temperature sensors sensor break detection
- the self-test method can be switched off via a parameter, which corresponds to a blockage of the self-test method for specific users, depending on the desired application.
- the self-test method can thus be reserved solely for remote diagnosis. All times and temperatures are to be taken from an Excel spreadsheet stored in an internal memory or XML file. According to the present invention, the following table results by way of example:
- the self-test can be started in a special mode.
- the selection is displayed on the display panel 17, as is the case in FIG. 4.
- a display and control panel 61 with a display section 63 in which display fields 65 are indicated with the digits 1 to 9 for the individual test steps or actuators.
- a control lamp 67 is provided in each display field 65, which lights up green in the successful test or test step and lights up red if the test is unsuccessful.
- a display panel 69 is provided which displays the current status.
- the test can be started, aborted or interrupted.
- With a reset field 71 the program or the test step can be reset.
- the fields 71 and 73 can be displayed, for example, for all inputs similar or equal, so even with cooking programs.
- the expected values for the current device are stored in a file (such as XML) that is automatically overwritten when the learn mode is run. Thus, special designs can easily be provided with the expected values. This file will not be overwritten during an update. If the device-specific file does not yet exist when the self-test is started, the corresponding values are read from a central file and written to the device-specific file. The values for all common variants are stored in the central file and can be selected automatically using a combination of device type and heating type. This may be overwritten during the update.
- the test procedure is described below.
- the cooking appliance 1 is in an initial state:
- LOA external power optimization system
- the device can be completely tested within approx. 25 minutes.
- the result and the date of the last self-test are displayed.
- the test can be initiated via the network connection (Ethernet, see above).
- the test of the door or the reed contact of the door must be carried out in advance.
- the device checks whether the following temperatures are below 50 ° C: cooking space temperature, core temperature sensor, if necessary humidity sensor. If this temperature is exceeded, the test program is aborted and an error message "Device too hot". If the temperatures are in the desired range, the test begins.
- the device is always operated so that the fan rotates only in one direction (for example, constantly right) and with the speed level "fast”. All tests run in succession.
- the user is first caused to close the cooking chamber door 7 and the program starts. However, if the door is opened again after the test of the door contact in a later test step, the test is aborted and a corresponding message is issued "door was opened, test aborted". Preferably, in such a case, the test must be completely repeated.
- FIG. 8 shows the corresponding self-test step or program step starting with the color-contrasting first field 65, so that the operator recognizes that this test or step is being carried out. If the test or program step is successful, the control lamp 67 lights up green.
- the cooking appliance shown in FIGS. 1 to 3 has a cooking chamber 6.
- the self-test method according to the invention is also suitable for so-called dual-chamber devices, ie cooking devices with two chambers, with all facilities that are arranged one above the other, with their cooking chambers are not separated, but form a cooking chamber. Both chambers are always operated and the test takes place simultaneously in both chambers. The temperature measurement takes place simultaneously for the individual chamber, ie no mean value is processed.
- the door 7 When starting the self-test, the door 7 must be closed.
- the test is not started, as otherwise a defect of the door contact is not clearly recognized. Instead, an indication is displayed, as it results from Fig. 7 "Please close the door and restart".
- the function of the door contact must be ensured in order to be able to carry out the self-test procedure.
- the operator In order to carry out the test requirement, the operator must open and close the door once again within a predetermined time interval, for example 60 seconds, as requested in accordance with FIG. 8. If the test is allowed over a network connection, check if the door is closed. After closing the door, the display is hidden as shown in FIG. 8 and then indexed to the next display, depending on the previous selection. The test of the door contact is only completed when the signal lasts for at least two seconds. This ensures that the door is locked in place.
- the present invention proposes that if the door is not opened and closed within the predetermined time period, the door contact test is deemed to have failed and the complete self-test with the corresponding result display is displayed as completed.
- This preparation includes the cleaning of the siphon or the liquid reservoir of the cleaning cycle system, as it is present in such cooking appliances. This is necessary because the content of the liquid reservoir is later promoted in the oven. However, that is This preparation is only necessary if the operator has selected "Total Test” or "Test Cleaning".
- the preparation is accomplished by actuating the drain pump for, for example, 20 seconds and then turning on the vapor control valve for 20 seconds. If necessary, this procedure is repeated once or several times.
- step 3 begins the total test in step 3, as shown in Fig. 10 can be seen by testing the heating power.
- the device is heated to 95 ° C for three minutes.
- the hot air mode is set and the fan mode "permanently right" is selected.
- the time is determined, which elapses until the cooking chamber temperature, determined by temperature sensor 35, has risen from 50 ° C to 90 ° C.
- the set time is stored in the cooking appliance, for example 60 seconds + 10 seconds / - 20 seconds. For example, if one phase is missing, the time required is 120 seconds, as shown in FIG.
- the test can thus be used to reliably determine whether a phase is missing, so that only half the heating power is available (twice the heating time). Furthermore, it can be determined whether one of the two solid state relays is defective (longer heating time) or both are defective (device does not heat at all);
- the self-test method continues in the context of the climate test with the test of steaming, as shown in Fig. 1 1 continues.
- the device is kept at the temperature for example four minutes from the previous test. This will test the temperature controller in the lower temperature window. The actual temperature must be within the limits of 95 ° C ⁇ 3K, and the temperature must be kept stable in the oven. Then the setpoint is lowered to 30 ° C. Now the steaming is activated. In this case, a sufficiently large temperature drop must be registered. For example, the temperature must drop by 10 Kelvin + 10 Kelvin - 2 Kelvin within 60 seconds. If the humidification does not work, For example, the drop is only 2 Kelvin in 60 seconds, as shown, for example, by curve 56 in FIG.
- the setpoint temperature is lowered, for example, to 30 ° C. after the heating has been switched off.
- the previous test has already heated up the existing humidity sensor so that the supply air flap can be opened directly at the beginning of the test.
- the temperature of the humidity sensor must fall faster than during cooling without dehumidification, for example in 60 seconds by at least 15 Kelvin + 10 Kelvin / - 5 Kelvin. If the waste is lower, the supply air damper is defective. If the values differ slightly, it is possible to conclude that there is a blocked or delivered supply air flap.
- the circulating pump 49 is tested.
- the device is operated in the hot air mode at 90 ° C, for example, three minutes.
- the heating is switched off and the setpoint temperature is lowered to 30 ° C.
- the circulation pump 49 is activated for 30 seconds.
- the cooking chamber temperature must fall by 15 Kelvin + 10 Kelvin / - 5 Kelvin. If this temperature drop, as shown in FIG. 20 with curve 59, is lower, the circulating pump is defective.
- the vapor release valve 47 is opened for 10 seconds to fill the liquid reservoir. By a slight deviation from the expected temperature curves, for example, a partially clogged pump can be detected.
- the setpoint temperature is set to 90 ° C and heated for essentially two minutes. Then, for example, the cooking program is stopped for 30 seconds (waiting time).
- the vapor control valve 47 is operated for about 20 seconds. Announce activated.
- the steam temperature must drop by 10 Kelvin + 10 Kelvin / - 5 Kelvin within the opening time of the waker-off valve of 20 seconds. If this temperature drop is not reached, the vapor control valve is defective.
- the cleaning test is then followed by the test of the siphon or drainage pump 51 as the next step. First, the drainage pump 51 is switched on for approximately 20 seconds in order to empty the liquid reservoir.
- the cooking appliance in the hot air mode 130 ° C operated the fan 29, for example, is operated continuously right.
- the circulation pump 49 is turned on during the heating phase.
- the appliance must reach a cooking chamber temperature of 130 ° C + 10K -5K. If this is not achieved, the drain pump 51 is defective.
- the reason for this is that with the circulation of liquid an increase of the temperature in the cooking chamber of well over 100 ° C is not possible (evaporation temperature of water). An increase takes place only when the water has evaporated, ie the drainage pump 51 has emptied the liquid reservoir.
- the liquid reservoir is replenished, which is done by first the circulation pump 49 is turned off, and then only the Wrasenelöschventil 47 is turned on for substantially 20 seconds.
- the test is performed at reduced power to avoid complete evaporation of the water.
- the temperature control can still be tested as shown in FIG. 16, wherein by means of the operating mode hot air (fan rotation continuously right) is operated at 140 ° C for five minutes.
- the cooking chamber temperature must be in the range of 140 ° C +/- 3 K in the last two minutes.
- Fig. 17 the test evaluation is shown in boxes 65 and 69, indicating which components have been tested and all indicator lights 67 are lit green. However, if it has been determined that a test has failed, such as that of the circulating pump 49, then, as shown in Fig. 18, in the cleaning test No. 6, the pilot lamp 67 will light up red. A corresponding information is provided in field 69.
- the functionality of the fan 29 can be detected for example by significant temperature differences in the oven. For example, this can be done by comparing the measured values of oven temperature sensor 35 and core temperature sensor (not shown). If the door contact or heating power is not good, the test will be aborted as other tests will not work.
- test of the circulation pump 49 is negative, the result of the vapor outflow valve 47 and the drainage pump 51 is not evaluated or these two tests are not performed. The test result is however logged.
- the self-test can be started as a remote diagnosis.
- a wired or wireless connection to the cooking appliance can be used.
- this self-test can be initiated via an Ethernet connection.
- the protocol for the kitchen control technology is used.
- the self-test can be started, stopped or evaluated via an additional command and an action number.
- the operability of the cooking appliance displayed to the operator or any errors and defects can also be displayed.
- the remote device from the outside to learn through the self-test which components of the cooking device may be defective. This helps to provide the necessary spare parts targeted.
- the self-test procedures can also be used to test new equipment and calibrate it to prevent partial equipment from being shipped.
