Definitions

  • the present invention refers to a dishwashing appliance, comprising a cabinet with a compartment to receive articles to be washed and a door used to close said compartment, said cabinet and said door being provided with a device for retaining and automatic opening of the door.
  • an automatic door opening system with a dishwashing appliance is primarily to reduce the energy consumption as the temperature of the final rinse can be lowered.
  • the drying time can be shortened and the drying performance improved by automatic door opening.
  • Various solutions of automatic door opening are known, which comprise either a directly actuator driven device that pushes the door to an open ventilation position, either comprise an actuator that releases a door latch by shifting hooks thereof and the door is then moved to a ventilation position by means of a spring system. Both solutions require a rather powerful actuator or an actuator driven device with a large gear ratio in order to overcome the retaining force of the door latch.
  • Fig. 1 shows a simplified view of a dishwashing appliance
  • Fig. 2a, 2b, 2c shows a door latch in a view from above, in various positions during closing the door
  • Fig. 3 shows a front cross-sectional view of a door in a locked position
  • Fig. 4 shows a front cross-sectional vies of a door in an unlocked position.
  • a dishwashing appliance 1 comprises a cabinet 2 with a compartment to receive articles to be washed, and a door 3 to close said compartment.
  • the door 3 is articulated in the lower area of the body 2 by means of hinges 4.
  • a resilient means 5 connected to the door 3, said resilient means 5 continuously acts on the door 3 so that it tries to force the door 3 in the open position.
  • Said body 2 and the door 3 a provided with a device 6a; 6b for retaining and automatic opening of the door 3.
  • Said device for retaining and automatic opening of the door 3 comprises a latch 6a that is arranged on and, respectively, in the body 2 preferably at the end opposite to said hinges 4, and a retaining element 6b that is preferably arranged in the door 3 in order to cooperate with the latch 6a.
  • a latch 6a that is arranged on and, respectively, in the body 2 preferably at the end opposite to said hinges 4, and a retaining element 6b that is preferably arranged in the door 3 in order to cooperate with the latch 6a.
  • an embodiment of the device 6a; 6b for retaining and automatic opening of the door 3 is possible, where the latch 6a is arranged in the door 3 and the retaining 6b is arranged on and, respectively, in the body 2 of the dishwashing appliance 1.
  • Said latch 6a is known per se and comprises a pair of holders 7, 8 extending approximately in parallel and lying approximately in a horizontal plane, each first end of said holders 7, 8 cooperating with the retaining element 6b is formed with a hook 7', 8', whereas each opposite end of the holders 7, 8 is connected with a resilient means 9 which forces said hooks 7', 8' towards each other in said horizontal plane.
  • Said hooks 7', 8' faces each other and are formed in a manner that they are movable against each other and in the direction.
  • said retaining element 6b is arranged in the door 3 opposite to said latch 6a and is movable in the vertical plane i.e. approximately perpendicularly to the plane in which said holders 7, 8 rest and operate.
  • the door 3 comprises a cavity 11 in which a body 12 of the retaining element 6b is arranged with a waterproof fit and movable along the height of the door 3.
  • a retaining section 14 is attached to the end of said body 12 which faces the upper edge 10 of the door, said retaining sectionl4 protruding through an associated opening 13 in said edge 10 of the door and is configured to cooperate with said hooks 7', 8' of the holders 7, 8 of the latch 6a.
  • Said opening 13 is preferably formed in the dry area of the upper edge 10 of the door 3. Water that would potentially penetrate the gap between said opening 13 and the retaining section 14 is redirected away form all electrical parts. Said redirection is achieved by means of drainage channels formed on the retaining section 14 and similar. In general, however, the fit between the retaining element 6b and the door 3 is formed in a manner of a labyrinth sealing.
  • the retaining section 14 of the retaining element 6b is formed in a manner that the height thereof approximately equals the thickness of the hooks 7', 8' and that the transversal measurement thereof, i.e. the measurement in the direction which usually denotes the width of the dishwashing appliance 1, is grater than the spacing between the hooks 7', 8' of the latch 6a.
  • the retaining section 14 is formed as a prism the base thereof resembles an approximate form of a rhombus, thereby facilitating an engagement with the hooks 7'. 8'.
  • the hooks 7', 8' effortlessly slides over oblique sides of the retaining section 14 and, respectively, of the prism, either when closing or opening the door 3.
  • hooks 7', 8' engages and, respectively, disengages with the retaining section 14 they slides over the sides of said prism, whereby said hooks 7', 8' execute mutual back and forth movement approximately in the horizontal plane as the dishwashing appliance 1 is located.
  • the latch 6a and the retaining element 6b can be formed in a manner that the faces thereof which cooperate during opening and, respectively, closing the door 3 are either vertical or inclined. In the latter case, even easier disengagement of the retaining section 14 and the hooks 7', 8' can be achieved.
  • the retaining element 6b is connected at the side opposite to the retaining section 14 with an actuator 15.
  • Said actuator 15 which is fixed in said cavity 11 is preferably selected as a linear actuator, i.e. an actuator executing a linear motion, such as solenoid, a wax actuator and similar.
  • the retaining element 6b is located in a locked position, meaning that the retaining section 14 protrudes out of the opening 13 over the door edge 10 for the amount which equals the vertical measurement and, respectively, the thickness of the holders 7, 8 and, respectively, the hooks 7', 8'.
  • the retaining section 14 slides between the hooks 7', 8' which to this end open and embrace said retaining section, thus, holding the door 3 in the closed position.
  • said actuator 15 is released by means of a control unit, acting on the retaining section 14 in a manner to pull it through the opening 13 inside the door 3 until it is approximately aligned with said door edge 10 and, respectively, until disengagement with the hooks 7', 8' is completed. Afterwards, said resilient means 5 pushed the door 3 into the open position, and said actuator 15 pushes the retaining section 14 back into the start position. It is obvious, that the functioning of the actuator can be switched off, so that the user of a dishwashing appliance manually handles the door.
