Title: AIR EXTRACTING PUMP ASSEMBLY AND REFRIGERATING AND FREEZING DEVICE
Abstract:
An air extracting pump assembly (10) and a refrigerating and freezing device. The air extracting pump assembly (10) comprises a mounting bottom plate (100), a seal box (200), and an air extracting pump (300). A stop portion (110) upwards extending is disposed on the rear part of the upper surface of the mounting bottom plate (100), and the front surface of the stop portion (110) is backwards recessed to form a fixing recessed portion (112). The seal box (200) is provided an air inlet connecting pipe (510) and an air outlet connecting pipe (520) communicating with corresponding inside spaces and outside spaces thereof, and the air inlet connecting pipe (510), the air outlet connecting pipe (520) and the seal box (200) are integrally formed. A fixing protruding portion (212) backwards protruding is formed on the rear part of the seal box (200). The seal box (200) is located on the upper side of the mounting bottom plate (100), the fixing protruding portion (212) is clamped into the fixing recessed portion (112), and the front part of the seal box (200) is locked to the mounting bottom plate (100). The air extracting pump (300) is disposed in the seal box (200) in a manner in which the axis of the air extracting pump (300) extends in the horizontal direction. An air inlet of the air extracting pump (300) is connected to the air inlet connecting pipe (510) by means of a hose (310), and an air outlet of the air extracting pump (300) is connected to the air outlet connecting pipe (520) by means of a hose (320). The air extracting pump assembly (10) has low running noise, is very convenient to disassemble and assemble in the refrigerating and freezing device, and occupies a small space in height.
