Definitions
- the invention relates to a temperature display device on a glass door a heating and / or cooling device, one visible from the outside Color change for temperature display.
- a temperature display device is in DE 198 36 732 A1 described.
- the element is preferably one on the inside of the door attached film that contains chemical substances that are present Color change visibly. Accordingly, it must Element should be designed so that it prevails in the oven withstands high temperatures. Such a temperature-sensitive Element is complex.
- thermochromic materials for temperature display described with which dangerous temperatures on radiators are identified.
- a temperature sensor for displaying the interior temperature of a Ovens are bimetallic or state of the art used electronic sensors that have a corresponding Electronics act on a display. Such circuits are complex, energy-dependent and expensive to manufacture.
- WO 97/26 486 and WO 97/34 490 are various Requirements for temperature display devices on the door of a Household oven known.
- AT 202 660 has a roasting tube for electric cookers on the door attached thermostatic controller described.
- the controller is arranged between two shells of the door.
- a heat sink transfers the heat of the inner shell of the door to a bimetal.
- a signal lamp is provided to show the switching status.
- DD 234 298 A1 is a pressure sensitive adhesive film for temperature display known. This is used to display the temperature on electrical household appliances.
- JP 11351729 A describes a device for displaying the internal temperature of a refrigerator. For this purpose, it has a thermochromic Limb on.
- the object of the invention is a temperature display device provide that reaching a certain temperature range in the interior of a heating and / or cooling device by changing the color displays, avoiding that the temperature display device with a heater due to the high furnace interior temperatures is damaged.
- the above object is for a temperature display device of the type mentioned by the characteristics of Claim 1 solved.
- thermochromic layer between two discs of Glass door is provided, it is only indirectly related to the furnace interior temperature exposed.
- the maximum furnace interior temperature does not occur at it on. Therefore, an inexpensive thermochromic layer thermosensitive color layer can be used, for example in Screen printing process or as a film, preferably polymer film, on the can apply the relevant disc.
- the temperature display device is therefore much cheaper than a corresponding electronic Temperature indicator.
- thermochromic layer does not show the door temperature, but the furnace interior temperature is shown.
- Two or Multi-pane glass doors are designed so that their outside temperature is harmless to users. That is why a warning from the user not necessary before a high door temperature.
- the point at which the thermochromic layer is applied is preferably is selected so that at a maximum furnace interior temperature of about 280 ° C to 300 ° C the temperature at the layer 120 ° C does not exceeds.
- Thermosensitive paints that are not damaged at 120 ° C are known on the market.
- thermochromic layer applied to the outermost pane of the glass door.
- the temperature display device described can also be used in others Furnaces for displaying a characteristic or the currently prevailing Internal temperature can be used.
- An example of using the display device according to the invention is the display of the so-called Residual heat.
- the residual heat is the in after switching off the furnace whose interior denotes the remaining heat.
- a domestic oven has a glass door (1) according to Figure 1, on the a handle (2) is attached. Over this are different Adjustment elements (3) are provided.
- the glass door (1) has a crystal clear transparent central area (4) and decorated Edge areas (5).
- the glass door (1) consists of two or usually three panes, namely an outer pane (6), a central pane (7), and one Inner pane (8).
- an outer pane (6) Inside on the outer pane (6) is in the bottom Edge region (5) a thermochromic layer (9) applied, which a thermosensitive color, which, for example, in Screen printing process, printed on the outer pane (6) or as Polymer film is applied.
- the area that the thermochromic layer (9) is large enough to be easily seen from the outside.
- the thermochromic layer (9) can be in the form of a lettering or a Icon be designed.
- the maximum achievable temperature in the interior of the furnace (10) is for example 280 ° C.
- Tests have shown that at the point (11) the outer pane (6) on which the thermochromic layer (9) is provided is not exceeded at 105 ° C at maximum furnace temperature be what the deep location of the site (11) and the thermal insulation of the Center disc (7) and the inner disc (8) and the distances between the inner pane (8) and the middle pane (7) and the middle pane (7) and the outer pane (6) can be traced back.
- There can be one Use a thermo-intensive surface that is reversibly color stable up to 105 ° C is.
- the thermochromic layer (9) is selected so that it Furnace internal temperature of about 45 ° C of one color, for example white, changes to green. At an oven temperature of 40 ° C to 45 ° C, the temperature at the thermochromic layer (9) is about 30 ° C. The thermochromic layer (9) goes when the Internal oven temperature of 280 ° C when the Color change temperature from white to green above.
- the thermo intensive Color is chosen so that the color change temperature is reached when the furnace interior temperature is about 50 ° C to 60 ° C. This is the temperature at which in an oven cleaning program best results can be achieved.
- the user recognizes from the Color change that the right temperature to enter a Cleaning liquid in the oven interior (10) is reached. It opens then the glass door (1), enters the cleaning liquid and closes it Glass door (1). After that the heating of the oven is done manually or switched on again programmatically, the cleaning liquid evaporates and their vapors loosen incrustations in the interior of the oven.
- the display device according to the invention can also be used to display the Residual heat in the furnace interior (10) can be used. It changes the color of the display when the residual heat temperature changes from about up to 160 ° C to a lower temperature the color. So it can Residual heat can be used.
- thermochromic to be used Layer (9) at other points on the panes (6, 7, 8) be provided.
- a refrigerator has a glass door (1) according to FIG Handle (2) is attached.
- the glass door (1) consists of two or in the Rule of three discs, namely an outer disc (6), one Center disc (7), and an inner disc (8).
- Inside on the The outer pane (6) is preferably four thermochromic layers (9) applied, which consist of thermosensitive paint, which, for example in the screen printing process, on the outer pane (6) printed or applied as a polymer film.
- the area that the occupies thermochromic layer (9) is large enough to cover it from the outside to be able to see well.
- the thermochromic layer (9) can be in the form a lettering or a symbol.
- the thermochromic Layer (9) is selected so that it is at an internal temperature of about 5 ° C the color changes.
