detailed description:

As shown in FIG. 1 to FIG. 2, a vacuum packaging device for a refrigerator according to the present invention can be disposed at any position on the front or side of the refrigerator 20, and includes a control panel 1 and a vacuum extraction device 2. :

The control panel 1 is disposed on the front of the refrigerator (the side facing the user). The control panel 1 includes a long groove 10, a display area 11, and a control area 12. The long groove 10 is used for The packaging bag to be vacuum-packed is sent into the vacuum pumping device 2. The display area 11 is used to display the working status of the vacuum pumping device 2. A number of buttons are set on the control area 12 to control the actions of the vacuum pumping device 2.

The evacuation device 2 includes an upper seat 21, a lower seat 22, and the upper seat 21 and the lower seat 22 form a closed cavity 23. The upper seat 21 and the lower seat 22 are connected by a guide post 24, and maintain contact or non-existence along the guide post 24. The contact state, in which: the upper seat 21 and the lower seat 22 remain in a non-contact state in a non-operating state; the upper seat 21 and the lower seat 22 remain in a contact state during the vacuuming process. At this time, the upper seat 21 and the lower seat 22 constitute A closed cavity 23 is provided with a sealing ring 27 between the upper seat 21 and the lower seat 22 in order to obtain a better sealing effect.

A driving device 25 and a reset device 26 are provided on either end of the upper seat 21 and the lower seat 22. In the embodiment shown in FIG. 3, the driving device 25 and the reset device 26 are disposed on the lower seat 22 and are used to control the lower seat 22. The driving device 25 can be selected from motor driving, hydraulic driving, and cylinder driving. In this embodiment, the driving device 25 is driven by a cylinder, and the resetting device 26 is a resetting spring.

The upper seat 21 is provided with an air inlet hole 210 and an air outlet hole 211. The air inlet hole 210 and the air outlet 211 communicate with the cavity 23, respectively. The air outlet hole 211 is connected with an air exhaust motor 213, the air inlet 210 and The exhaust holes 211 are controlled by the control panel 1 respectively.

A positioning device 4 is provided in the cavity 23. The positioning device 4 is used to position the packaging bag entering the cavity 23. The distance between the positioning device 4 and the elongated groove 10 of the control panel 1 is the packaging bag. The width of the sealing area. In this embodiment, the positioning device 4 includes a blocking piece 41 provided on the upper seat 21 and a blocking groove 42 provided on the lower seat 22. The blocking piece 41 and the blocking groove 42 are fastened to each other.

Between the positioning device 4 and the elongated groove 10, a hot-melt sealing device 5 is provided for hot-melt sealing the evacuated packaging bag. In this embodiment, the hot-melt sealing device 5 uses a hot-melt strip. The hot-melt strip is arranged at either end of the upper seat 21 and the lower seat 22.
