Embodiment 1

[0046] Such as Figure 1 to Figure 9As shown, the present invention discloses an automatic door opening device, including a first door opening mechanism 100, which is arranged in the direction of opening and closing the door body, and can be telescopically moved to open the door body; a second door opening mechanism 200, the second door opening mechanism 200 cooperates with the first door opening mechanism 100 to keep the door body at a set opening angle.

[0047] As an implementation manner, the first door opening mechanism 100 opens the door by pushing the door. After the first door opening mechanism 100 opens the door body, the second door opening mechanism 200 cooperates with the first door opening mechanism 100 to keep the door body at a set opening angle, so as to facilitate steam discharge and reduce energy loss.

[0048] As an embodiment, the second door opening mechanism 200 includes a fixed plate 201, a hinge 202, a limit block 203, a first pulley 204, a second pull...

Embodiment 2

[0052] This embodiment is a further limitation or optimization of Embodiment 1.

[0053] The limit block 203 is provided with a perforation, and the through hole allows the pull cord 206 to pass through, so that the limit block 203 moves simultaneously with the pull cord 206 .

[0054] refer to Figure 1-2 , the limit block 203 is located between the hinge 202 and the second pulley 205, the second pulley 205 is located above the first pulley 204, the hinge 202 is located above the second pulley 205, and the second pulley 205 is provided with a pull cord 206 sliding chute, the position of the chute close to the hinge 202 has a limiting structure of the stopper 203 . The first pulley 204 and the second pulley 205 are arranged on the casing of the electrical appliance, and the first pulley 204 and the second pulley 205 are arranged on different sides of the stay cord 206 respectively, and the stay cord 206 is located between the first pulley 204 and the second pulley 205 The po...

Embodiment 3

[0059] This embodiment is a further limitation or optimization of embodiment 1 or 2.

[0060] Such as Figure 3-9 As shown, a first door opening mechanism includes a housing 1, a wax motor 2 and an ejector rod 3. The wax motor 2 is arranged in the housing 1 and has an output end 5. The ejector rod 3 passes through an elastic element 4 is arranged in front of the output end 5, so as to protrude or retract into the housing 1 along the door opening and closing direction when the wax motor 2 operates.

[0061] The first door-opening mechanism of the present invention has simple structure, few components, simple and stable setting, is not easy to be damaged and is easy to operate.

[0062] The housing 1 is provided with a first chamber and a second chamber communicated via a connecting piece 6, the wax motor 2 is arranged in the first chamber, one side of the connecting piece 6 is connected to the output The ends 5 are in contact with each other, and the other side is connected w...

Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to an automatic door opening device. The automatic door opening device comprises a first door opening mechanism and a second door opening mechanism, wherein the first door opening mechanism is arranged in the opening and closing direction of the door body and can stretch out and draw back to open the door body; and the second door opening mechanism is matched with the first door opening mechanism so as to enable the door body to be kept at a set opening angle. According to the automatic door openingdevice, the door body can be automatically opened and stably kept at a certain opening angle. In addition, the automatic door opening device is simple in structure, few in part, simple, convenient andstable in arrangement mode, not prone to damage and convenient to move. The invention further relates to an electric appliance provided with the automatic door opening device.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an automatic door opening device and an electrical appliance. Background technique [0002] The emergence of dishwashers has made important contributions to liberating labor and improving human life. At present, dishwashers are already a must-have household appliance. The washing, energy consumption, drying and other performances of the dishwasher are interrelated, and the change of parameters will improve one performance while restricting another performance. Dishwashers dry after rinsing. If the temperature is low, the water on the tableware will evaporate slowly, and there will be a lot of water remaining on the tableware at the end of washing, resulting in a low drying rate; if the temperature is high, the drying rate of tableware will increase, but it will increase Power consumption, low energy consumption level. In order to coordinate the drying r...
