Description

The invention relates to an ash container according to the preamble of patent claim 1.

An ash container of the type mentioned is used by the applicant in a solid fuel boiler, more precisely in a fully automatic pellet boiler, with the product name Vitoligno 300-C, d. H. Such an ash box serves to receive ashes produced by combustion of particular pellets. Said ash container consists of an ash box with a first closable opening for supplying ash in the ash box and with a second closable opening for discharging the ash from the ash box. During operation of the solid fuel boiler while the first opening is opened and the second opening is closed. If the ash container is full, it must be emptied, in which case the first opening is closed and the second opening is open.

In itself, this ash container has proven itself. The invention has for its object to further improve this ash container. In particular, while the reliability should be further increased.

This object is achieved with an ash container of the type mentioned by the features listed in the characterizing part of patent claim 1.

According to the invention, it is thus provided that the ash box is provided with a locking device preventing opening of the first opening when the second opening is open.

In other words, the ash box according to the invention is characterized in that the first (ash supply) opening can only be opened when the second (ash removal) opening is closed or that the solid fuel boiler can not be put into operation when the discharge opening is open. The locking device according to the invention provided for this purpose will be explained in more detail below.

Other advantageous developments of the ash box according to the invention will become apparent from the dependent claims.

The sake of completeness is still on the more distant document US 4,497,308 A pointed. This discloses an ash pan consisting of an ash box with a first closable opening for feeding ash into the ash pan and a second opening provided with a coarse dust filter for removing ash from the ash pan.

The ash box according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

FIG. 7

from above the ash container according to the invention FIG. 1 ,

The in the FIGS. 1 to 7 shown ash container consists in a known manner initially of a cuboid ash pan 1 with a first closable opening 1.1 for supplying ash in the ash pan 1 and with a second closable opening 1.2 for discharging the ash from the ash pan 1. As can be seen from the figures, is at provided in the illustrated embodiment that the first opening 1.1 is formed as an equally timed double opening.

Furthermore, it is provided in a manner known per se that the first opening 1.1 is arranged on a vertical side wall of the ash box 1 and the second opening 1.2 on a horizontal upper side of the ash box 1.

It is essential for the ash container according to the invention that the ash box 1 is provided with a locking device 2 which prevents opening of the first opening 1.1 when the second opening 1.2 is open.

Considered in more detail is, as before, the first opening 1.1 with a displaceably mounted on the ash pan 1 plate member 3 and the second opening 1.2 formed with a preferably provided with quick fastener lid member 4 closable. In this case, the plate element 3 (see in particular FIG. 3 ) in the open position a to the first opening 1.1 aligned through opening 3.2 (as already mentioned: here according to two times available). Further, the plate member 3 is provided for opening and closing the first opening 1.1 with a handle 8 (see in particular FIGS. 1 and 7 ).

Particularly preferably, it is further provided that the locking device 2 is formed on the one hand with the plate member 3 and on the other hand with the lid member 4 cooperatively.

It is on the one hand preferably provided (see FIGS. 2 and 3 ), that the locking device 2 with a closed first opening 1.1 and when the second opening 1.2 engaged in a Verrastungsausnehmung 3.1 on the plate member 3 intervening and preventing displacement of the plate member 3 relative to the ash box 1.

On the other hand, it is preferred (see FIGS. 4 and 5 ), that the locking device 2 with a closed second opening 1.2 is a displacement of the plate member 3 relative to the ash pan 1 permitting.

Once again considered in more detail, is, as before, the plate member 3 slidably mounted between the ash pan 1 and a cover 5, wherein furthermore the cover 5 has an always the first opening 1.1 aligned through opening 5.2 (as already mentioned: here accordingly two times available).

Particularly preferred is now provided that the locking device 2 is formed at the opening of the second opening 1.2 for closing guarantee of the first opening 1.1 simultaneously engages in a Verrastungsausnehmung 3.1 on the plate member 3 and in an abutment recess 5.1 on the cover 5. Without the cover element 4, the locking device 2, which is supported on the latching recess 3.1 on the one hand and on the abutment recess 5.1 on the other hand, thus effects that the plate element 3 can not be displaced in the open position.

Said locking device 2 is rotatably mounted on the ash pan 1 via a rotary joint 2.3. In addition, as is apparent from the figures, it is preferably provided that a arranged on one side of the pivot joint 2.3 first lever arm 2.1 of the locking device 2 with the lid member 4 and one on the other side of the rotary joint 2.3 arranged second lever arm 2.2 of the locking device 2 with the plate member 3 and the cover 5 is formed cooperatively. The angle between the two lever arms 2.1 and 2.2 to each other is not full 180 °, but preferably about 150 ° to 170 °.

In order to ensure a particularly simple handling, it is further preferably provided that the ash box 1 for its transport preferably at the bottom side with at least one transport roller 6 (shown are two) is provided. In addition, the ash box 1 for its transport on a preferably extendable, preferably on the lid member 4 (shown) or on the bottom side of the ash pan 1 (not shown) arranged on the handle 7. The ash container is thus designed as an easily manageable rolling suitcase.

• Ausgangspunkt sei wie im oben genannten Video die Situation, bei der sich der Aschekasten im Festbrennstoffheizkessel befindet und über die erste Öffnung 1.1 mit Asche befüllt wird. In dieser Situation, die insbesondere in Figur 1, 5, 6 und 7 dargestellt ist, ist die zweite Öffnung 1.2 mit dem Deckelelement 4 verschlossen.

The ash container according to the invention works as follows:

• The starting point, as in the above-mentioned video, is the situation in which the ash box is located in the solid fuel boiler and is filled with ash via the first opening 1.1. In this situation, in particular in FIGS. 1, 5, 6 and 7 is shown, the second opening 1.2 is closed with the lid member 4.

If the ash container is full, it must be emptied. This happens because a user moves the plate element 3 via the handle 8, so that the first opening 1.1 is closed. Since the cover member 4 in the closed position thereby ensures that the pivotally mounted locking device 2 is not in the Verrastungsausnehmung 3.1 and the abutment recess 5.1 engages, this displacement of the plate member 3 is easily possible in this situation.

Completely closed in this way, the ash container can now be removed from the solid fuel boiler. After releasing said quick-release closures, the cover element 4 can be opened and the collected ash emptied.

If one would now reset the ash container without its cover element 4 in the solid fuel boiler, the inventive preferably gravity, but alternatively spring-actuated locking device 2 would ensure that the user can not move the plate member 3 in the open position, since the second, in the Verrastungsausnehmung 3.1 engaging lever 2.2 prevents this movement. This excludes operation of the solid fuel boiler without cover element 4.

Only when the lid member 4 has been properly placed on the ash pan 1, via the locking device 2 is a movement release for the plate member 3 and thus the ability to open the first opening 1.1 by appropriate displacement of the plate member 3.

Finally, it should be noted that, for additional assurance that the placement of the lid member 4 after emptying was not forgotten, for example, on the lid member 4, a donor element 9 is arranged, which cooperates with a provided on solid fuel boiler sensor via the control of the solid fuel boiler ensures that it can not go into operation when the cover element 4 is missing.
