But since the anti-condensation duct 42 in the fixed beam 4 is disposed between the metal plate and the insulating layer, and is not connected to the wire harness 434, the anti-condensation duct 42 in the fixed beam 4 can continue to be electrically heated when the connection between the metal sheet 314 below the movable beam 31 and the metal block 431 above the fixed beam 4 is broken.
As shown in fig. 3, the first freezer drawer 3 of the refrigerator is shown in a closed position. The first freezing drawer 3 is arranged above the second freezing drawer 7, the movable beam 31 and the fixed beam 4 are arranged on the same vertical direction, when the first freezing drawer 3 is closed, the movable beam 31 and the fixed beam 4 are contacted, namely, the fixed block 315 arranged below the movable beam 31 and the metal block 431 arranged above the fixed beam 4 can be contacted.
When the first freezer drawer 3 is closed, the metal sheet 314 below the movable beam 31 is connected to the metal block 431 above the fixed beam 4, the heater 313 in the movable beam 31 is also energized, the heater 313 in the movable beam 31 starts heating, the wire harness 434 in the fixed beam 4 is also energized, and the wire harness 434 in the fixed beam 4 also starts heating. Meanwhile, because the condensation preventing pipe 42 in the fixed beam 4 is arranged between the metal plate and the insulating layer and is not connected with the wire harness 434, the condensation preventing pipe 42 in the fixed beam 4 can still be electrified and heated without being influenced by the closing or drawing of the first freezing drawer 3.
The movable beam 31 is heated by an electric heater 313, the electric heater 313 adopts a power supply mode of contact connection, a contact connection device is arranged between the movable beam 31 and the fixed beam 4, when the first freezing drawer 3 is closed, the elastic component 43 of the fixed beam 4 is compressed and is contacted with the metal sheet 314 of the movable beam 31, and at the moment, the electric heater 313 in the movable beam 31 is electrified to work; when the first freezer drawer 3 is pulled open, the elastic component 43 is separated from the metal plate 314 and is in a reset state, and at this time, the electric heater 313 is powered off and heating is stopped. The anti-freezing pipe 42 is arranged around the elastic component 43 to prevent the elastic component 43 from freezing, and the mode has the advantages of high reliability, low cost and simple assembly.
In some embodiments, the number of metal sheets 314 is greater than or equal to two, and the number of metal blocks 431 is greater than or equal to two.
As shown in fig. 9, the number of the metal blocks 431 may be two, and if the width of the metal blocks 431 is designed to be narrower or the size of the fixing holder 435 is designed to be larger, the number of the metal blocks 431 may be designed to be larger. More metal blocks 431 are designed, so that more contacts can be ensured when the movable beam 31 is in contact with the fixed beam 4, if one or more contacts cannot be in normal contact, other contacts can still be in normal contact connection, and the heating device in the movable beam 31 is electrified to work. The stability of the contact connection between the movable beam 31 and the fixed beam 4 is higher.
In some embodiments, the present application further comprises a controller and a contact sensor, the controller being connected to the contact sensor and the electric heater 313, respectively; the contact sensor is arranged between a metal sheet 314 on the fixed beam 4 and the metal block 431 on the movable beam and is used for detecting whether the metal sheet 314 contacts the metal block 431; the controller is further configured to: if the metal piece 314 contacts the metal block 431, the electric heater 313 in the movable beam 31 is controlled to generate heat. If the metal piece 314 is out of contact with the metal block 431, the electric heater 313 in the movable beam 31 is controlled to stop generating heat.
As shown in fig. 4 and 5, the first freezer drawer 3 of the refrigerator is drawn out. The movable beam 31 is provided on the outer side of the first freezer drawer 3, and the metal piece 314 is provided at the lower end of the movable beam 31. When the first freezer drawer 3 is drawn out, the movable beam 31 is not connected with the fixed beam 4, that is, the metal sheet 314 arranged below the movable beam 31 is not connected with the metal block 431 arranged above the fixed beam 4, and after the contact sensor arranged between the metal sheet 314 arranged on the fixed beam 4 and the metal block 431 arranged on the movable beam detects that the contact is broken, a message that the metal sheet 314 is disconnected from the metal block 431 is sent to the controller, and the controller controls the electric heater 313 in the movable beam 31 to stop heating.
As shown in fig. 3, the first freezer drawer 3 of the refrigerator is shown in a closed position. When the first freezing drawer 3 is closed, the metal sheet 314 below the movable beam 31 is connected with the metal block 431 above the fixed beam 4, and after the contact between the metal sheet 314 arranged on the fixed beam 4 and the metal block 431 on the movable beam is detected by the contact sensor, the contact between the metal sheet 314 and the metal block 431 is sent to the controller, and the controller controls the electric heater 313 in the movable beam 31 to generate heat. The wire harness 434 inside the fixed beam 4 is thus also energized, and the wire harness 434 in the fixed beam 4 also starts to heat up. Meanwhile, because the condensation preventing pipe 42 in the fixed beam 4 is arranged between the metal plate and the insulating layer and is not connected with the wire harness 434, the condensation preventing pipe 42 in the fixed beam 4 can still be electrified and heated without being influenced by the closing or drawing of the first freezing drawer 3.
The heating devices in the movable beam 31 and the fixed beam 4 are controlled through the contact connection between the metal sheet 314 arranged below the movable beam 31 and the metal block 431 arranged above the fixed beam 4, and when the first freezing drawer 3 is drawn out, the heating is stopped because the connection between the metal sheet 314 arranged below the movable beam 31 and the metal block 431 arranged above the fixed beam 4 is broken; when the first freezer drawer 3 is closed, the heating means in the movable beam 31 is energized to start heating because of the contact between the metal plate 314 provided below the movable beam 31 and the metal block 431 provided above the fixed beam 4.
An anti-condensation pipe 42 is arranged around the elastic component 43, and the temperature of the anti-condensation pipe 42 during operation can ensure that the elastic component 43 cannot be frozen. The contact connection between the metal block 431 and the metal sheet 314 has simple structure, low cost and good reliability.
The detailed description provided above is only a few examples under the general concept of the present application, and does not constitute a limitation to the scope of the present application. Any other embodiments that can be extended by the solution according to the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
