Gargerätekombination

description

The present invention relates to a cooking appliance combination having at least two cooking appliances, each having a cooking chamber which is closable with a door and a discharge line for the discharge of air, vapors and other liquids from the cooking chamber. The cooking appliances have an upturned exhaust pipe, which serves to discharge the exhaust air from the cooking chamber.

For cooking appliances, especially those in which additional steam is cooked, as is the case with combi steamer, the steam in the cooking chamber, especially for safety reasons, should be removed before opening the cooking chamber door. However, the upward discharge into the environment of the cooking appliance is disadvantageous, so that condensation devices have been developed in order to remove the moisture of the exhaust air and then release only the dehumidified exhaust air into the environment again. Such a condensation device is known, for example, from the German Utility Model DE 203 17 601 U1 of the Applicant, to which reference is made here.

The condensation device for condensing moisture from the exhaust air of the cooking appliance is arranged on the cooking appliance.

Modern demands on the current kitchen technology in the professional field, such as catering, have led to the solution of Gargerätekombinationen where at least two, if necessary, different cooking appliances are arranged one above the other, with the aim to operate both cooking appliances independently.

A cooking appliance combination of the prior art has to dehumidify the exhaust air to a condensation device above the upper unit, which is supplied to the exhaust air from both cooking appliances to dehumidify this exhaust air. The disadvantage of this solution is that the condensation device must be dimensioned so that they can dehumidify the exhaust air flow from both cooking appliances simultaneously, which requires a corresponding size, with the additional disadvantage that the condensation device must be operated at full power when the exhaust air should be dehumidified from only one cooking appliance.

The present invention is therefore based on the object to provide a cooking appliance combination, in which the above-mentioned disadvantages are avoided and the efficient and space-saving dehumidification of the exhaust air from both devices and allows each other independently.

This object is solved by the features of claim 1.

According to the invention, a further, second condensation device is provided above the lower cooking appliance and below the upper cooking appliance, wherein the first condensation device, which is arranged above the upper cooking appliance, is connected exclusively to the exhaust pipe of the upper cooking appliance, and the second condensation apparatus, which is above the lower cooking appliance Gargerät is arranged, is exclusively connected to the exhaust pipe of the lower cooking appliance.

This advantageously ensures that the respective condensation device is adaptable to the size of the associated cooking appliance and only has to be put into operation if a corresponding dehumidification of the exhaust air is to take place.

Furthermore, there is the great advantage that the second condensation device can be used extremely space-saving in the space between the lower and the upper cooking appliance, whereby the height of the cooking appliance combination is not or only slightly increased. In particular, this is achieved in that the height of the second condensation device substantially corresponds to the height of the space between the lower and upper cooking appliance. The advantage is therefore particularly great because the space between the devices in each case must be kept to the installation for the supply of Electricity, water, cleaning agents, if necessary. Gas or to accommodate the necessary discharge. This leads to an optimal use of this installation space.

For optimized control of the condensation device, a temperature sensor for detecting the exhaust air temperature is provided below the upper connection of each exhaust pipe. With the detected temperature it is possible on the

Temperature of the exhaust air to act accordingly, i. to cool it down accordingly.

Each condensation device has a Kondensatabführleitung for discharging the condensates collected by the condensation device. Advantageously, the Kondensatabführleitung the first and second condensing device is connected to the exhaust pipe of the upper and lower cooking appliance for introducing the condensate in the exhaust pipe. Thus, all the condensate which forms both in the condensation device of the respective cooking appliance and in the exhaust pipe itself is discharged downwards in a device-technically simple manner.

In order to prevent the exhaust air introduced into the exhaust pipe from being too hot at the inlet to the condensation device, which can be detected by means of the temperature sensor, a water supply line is connected to the exhaust pipe, whereby cooling water can be supplied to the exhaust air pipe for cooling the exhaust air is.

Furthermore, a heat exchanger device is provided for cooling the exhaust air derived from the cooking chamber in the lower region of the exhaust air pipe. Advantageously, the heat exchanger device has a pipe socket which is arranged around the exhaust air pipe and can be conducted through the cooling water from top to bottom. The cooling water heated after heat exchange is then used to generate steam, which means energy can be saved when heating it up.

With further advantage, the second condensation device has an at least three-sided removable veneer, which connects flush to the upper and lower cooking appliance. This results in continuous side walls of Gargeräte- combination and also a correspondingly clean veneering of the front between the upper and lower door of the two cooking appliances, which allows a support of the purchase decision of the customer due to the optically flawless design. Conventional devices have condensation devices on their upper side, which can protrude over the contour of the device, especially on the front significantly. Such protruding edges are completely unsuitable for installation between the two cooking appliances not only for reasons of risk of accidents and non-visibility of the cooking chamber to be loaded. Advantageously, the unrestricted use of any working height is made possible by the proposed inventive solution.

To supply simple and effective cooling ambient air of the second condensation device, the veneer in the area between the upper and lower door of the cooking appliances ventilation slots for the entry of ambient air. As a result, advantageously not only the upper cooking appliance but also the lower cooking appliance when opening the door abruptly rising steam or moist hot air to be sucked into the second Kondesationvorrichtung and is at the safe back or laterally in the rear area in the mixture with further sucked in ambient air discharged again, where they are if necessary by means of the second condensation device ggfls. at least partially dehumidified.

Further details, features and advantages of the present invention will become apparent from the following description with reference to the accompanying drawings. It shows:

In the drawings, like elements have been given the same reference numerals.

In Fig. 1, a cooking appliance combination 1 according to the invention is shown in a perspective view from the front and left. The cooking appliance combination 1 has an upper cooking appliance 3 and a lower cooking appliance 5. Both cooking devices 3 and 5 are formed in the example trap as a combi steamer. They have a cooking chamber 7 or 8, to the access by a cooking appliance door 9 or 10 is made possible. The upper cooking appliance 3 has a control panel 1 1 and the lower cooking appliance 5 has a control panel 12. Furthermore, the upper cooking appliance, in particular for the cleaning of the cooking chamber 7, a hand shower 13 and the lower cooking appliance 5, a corresponding hand shower 14. Each cooking device 3 and 5 has two side walls, of which the left 15 and 16 in Fig. 1 can be seen.

The upper cooking appliance 3 has a first condensation device 21. In the illustrated example case, the upper condensation device 21 is similar to that known from German Utility Model DE 203 17 601 111. As can be seen from FIG. 1, the side dimensions thereof are adapted to the side dimensions of the upper cooking appliance 3. For supplying cooling air to the fans 23, a ventilation grille 25, which serves for the admission of ambient air to the upper condensation device 21, is located on the upper side in the front region of the upper condensation device 21, ie, virtually above the door 9. It occurs at the back or ggfls. also laterally in the rear region of the cooking appliance again. Between the upper cooking appliance 3 and the lower cooking appliance 5, a second condensation device 27 is provided. It is designed so that it fits into the intermediate space 4 between the upper cooking appliance 3 and the lower cooking appliance 5. As can be seen from FIG. 1, the second condensation device 27 has a facing 28 and 29 which terminates flush with the walls of the upper cooking appliance 3 and the lower cooking appliance 5, whereby flat side surfaces of the entire cooking appliance combination 1 are created. As can be further seen from FIG. 1, the second condensation device 27 also has a ventilation grille 30 on the front side, which likewise serves for the admission of ambient air to the ventilators (not shown here).

The lower cooking appliance 5 is, as shown in Fig. 1 and in a conventional manner, on four feet 31, two of which are visible in Fig. 1.

Reference is now made to Fig. 2, in which the cooking appliance combination 1 in Fig. 1 is shown in side view. The veneering of the first condensation device 21 with its lateral facing elements 22 and the front facing element 24 is explosively lifted upwards, and the veneering of the second condensation device 27 with its lateral elements 29 and the front element 28 is lifted laterally. Thereby, the structure of the first condensation device 21 and the second condensation device 27 will be better understood. Both condensation devices 21 and 27 have a plate capacitor 33 and 34, respectively, which will be described in more detail with reference to FIG. 5.

As is further apparent from Fig. 2, in front of the plate capacitor 33 of the first condensing device 21 there is provided a strip of fans 23 which serve to suck in ambient air and to convey it to the plates of the plate capacitor 33 for the purpose of heat exchange. The second condensation device 27 also has, in front of the plate capacitor 34, a strip of fans 35 which have the same function as the fans 23.

The upper plate capacitor 33 is connected via a connection 36 to an exhaust pipe, as described in more detail below, by reference to FIG. 4 will be. Similarly, the plate capacitor 34 of the second condensation device 27 is connected via a connection 38 with an exhaust pipe 39 of the lower cooking device 5.

2, behind the second condensing device 27 there is a discharge connection 21, which serves to discharge liquids from the upper cooking device 3, which takes place via a discharge line (not shown).

The upper cooking appliance 3 is supported on the lower cooking appliance 5 via four feet 43. Their length is dimensioned such that it corresponds to the height of the second condensation device 27.

In Fig. 3, the cooking appliance combination 1 according to the invention is shown in front view, wherein the delusions of the two condensation devices 21 and 27 are removed. Clearly recognizes that the plate capacitors 33 and 34 are arranged inclined to the respective terminal 36 and 38 downwards.

Reference is now made to Fig. 4, which shows a view of the cooking appliance combination 1 according to the invention analogous to that of Fig. 2, wherein the respective side wall 15 of the upper cooking appliance 3 or 16 of the lower cooking appliance 5 is partially broken away and the exhaust pipe 37 of Upper cooking appliance 3 and the exhaust pipe 39 of the lower cooking appliance 5 are shown schematically. As can be seen from FIG. 4, the upper cooking appliance has a discharge line 45 from the cooking chamber. The lower cooking appliance 5 has a corresponding discharge line 46. Both exhaust air and any resulting liquid is discharged via the discharge line 45 and 46 and fed to a siphon 47. In the siphon 47, exhaust air and effluent are separated. The exhaust air is passed to the exhaust pipe 37 and 39 of the upper cooking appliance 3 and the lower cooking appliance 5 and rises there according to chimney effect upwards. Via the connection 36 or 38, the exhaust air then passes into the respective plate capacitor 33 or 34 and in which the moisture contained in the exhaust air t is condensed. The resulting condensate is returned via a drain line 49 in the upper cooking appliance 3 and a discharge line 50 in the lower cooking appliance 5 in the exhaust pipe 37 and 39, wherein it then flows down. Each exhaust pipe 37 and 39 has below the terminal 36 and 38, a temperature sensor 51 which serves to detect the exhaust air temperature in this area, ie shortly before entering the respective plate capacitor 33 and 34 respectively. If it is determined that the exhaust air temperature is too high, which may affect the effectiveness of the condensation devices 21 and 27, cooling fresh water can be injected into the exhaust air pipe 37 or 39 via a fresh water supply line 53. As a result, the too hot exhaust air in the exhaust pipe 37 or 39 can be effectively cooled.

At each exhaust pipe 37 and 39 is still a heat exchanger device 55. The heat exchanger device 55 has a pipe socket 57 which extends around the respective exhaust pipe 37 and 39 in its lower region. Cooling liquid is fed into the pipe socket 57 via a feed line 59 and flows downwards in the pipe socket 57, after which the cooling liquid is discharged again through a discharge line 61. The cooling capacity of the heat exchanger device 55 can also be influenced by the temperature detected by the temperature sensor 51. The exhaust pipe 37 is connected via a connection 63 with the siphon 47. The exhaust pipe 39 is connected via a connection 64 with the siphon 47.

4, a further supply line 65 to the siphon 47 of the upper cooking appliance 3 or a supply line 66 to the siphon 47 of the lower cooking appliance 5 is provided. The supply lines 65 and 66 are each connected to a collecting strip (not shown) below the respective door 9 or 10 for catching condensation liquid draining on the door 9 or 10, which completely flows via the supply line 65 and 66 to the siphon 47 be derived and thus ausbringbar from the cooking appliance.

Reference is now made to FIG. 5, which schematically shows the plate condenser 33, the first condensing device 21, which is connected to the exhaust pipe 37 via the port 36, which in turn is connected to the siphon 47. The plate capacitor 33 has four superposed capacitor plates 69, 70, 71 and 72 in the illustrated embodiment of FIG. The connection 36 of the exhaust pipe 37 is connected to the uppermost capacitor plate 69. The capacitor plate 69 is connected via a corresponding connecting channel (not shown) to the capacitor plate 70, which in turn is connected via a corresponding connecting channel (not shown) to the capacitor plate 71 and the capacitor plate 71 is connected via a corresponding connecting channel with the capacitor plate 72. Furthermore, connecting lines for the condensate (not shown) are present, as is clearly described, for example, in DE 203 17 601 111. For discharging the dehumidified exhaust air, the lower condenser plate 72 has a ventilation slot (not shown) and the condensate draining from the four condenser plates is collected and discharged via the discharge line 49, the exhaust air tube 37 and the siphon 47 to the discharge nozzle 41.

The present invention thus provides a cooking appliance combination in which an effective dehumidification of the exhaust air is realized before discharge into the environment at the respective cooking appliance, wherein also an extremely space-saving design of Gargerätekombination is created in their overall height or the loan in substantially its height corresponds to the height of two superimposed cooking appliances.
