Description

Technical Field

[0001] This utility model relates to the field of drying cabinet technology, specifically to a drying cabinet for laboratory use. Background Technology

[0002] Laboratory desiccant cabinets are used to dry and store laboratory glassware. They primarily serve to provide a dry storage environment. Since a large number of glassware items need to be cleaned in the laboratory every day, such as volumetric flasks, beakers, centrifuge tubes, funnels, watch glasses, and microwave digestion jars, they need to be dried quickly in a desiccant cabinet after cleaning.

[0003] Currently, existing drying cabinets operate by using a hot air blower at the bottom of the cabinet, which outputs hot air. This hot air moves upwards from the bottom of the drying chamber inside the cabinet, drying the containers it passes over, removing any residual water, and then exhausting it through an exhaust duct at the top of the cabinet. To prevent dust and other debris from entering the drying cabinet through the exhaust duct, a dust filter is usually installed at the end of the exhaust duct. However, with the dust filter constantly exposed, it easily accumulates dust and other impurities, causing blockages. Furthermore, some small impurities can easily pass through the dust filter and enter the drying cabinet, causing contamination. Utility Model Content

[0004] The purpose of this invention is to provide a laboratory drying cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laboratory drying cabinet, comprising:

[0006] The cabinet has a door hinged to the front side. The cabinet has a drying chamber and an installation chamber inside. Multiple support frames are placed inside the drying chamber. A windproof and water-retaining cover is installed at the bottom of the drying chamber. A hot air blower is installed in the installation chamber. The output end of the hot air blower is connected to an air supply pipe. The upper end of the air supply pipe extends into the windproof and water-retaining cover.

[0007] An exhaust pipe is installed on the top of the cabinet. The top of the exhaust pipe is equipped with a cover, and multiple sliding rods are fixed at equal intervals on the bottom edge of the cover. The sliding rods are slidably connected to the exhaust pipe.

[0008] Preferably, the mounting cavity is located below the drying cavity, the suction end of the hot air blower is connected to a suction pipe, the end of the suction pipe away from the hot air blower extends to the outer surface of the cabinet, and a dustproof net is installed at the port of the suction pipe.

[0009] Preferably, the upper side of the air distribution water shield is arc-shaped, and multiple protruding pillars are fixed on the upper surface of the air distribution water shield. Ventilation holes are opened on the upper surface of the protruding pillars, and the ventilation holes communicate with the inner cavity of the air distribution water shield. A water baffle is provided above the protruding pillars. The bottom diameter of the water baffle is larger than the cross-sectional circle diameter of the protruding pillar. The water baffle blocks the upper port of the ventilation hole to prevent water dripping from the support frame from falling into the ventilation hole, thereby preventing water from entering the air supply pipe.

[0010] Preferably, a support rod is connected between the water-blocking plate and the top edge of the protruding column.

[0011] Preferably, a protective net is installed inside the exhaust pipe, and a sliding sleeve is fixed on the side wall of the exhaust pipe corresponding to the position of the sliding rod. The sliding rod slides through the sliding sleeve, and a limit block is fixed at the bottom end of the sliding rod, so that the cover moves up and down stably and the cover will not fall off.

[0012] Preferably, a rubber gasket is fixed to the top edge of the exhaust pipe to reduce the impact between the cover and the exhaust pipe when the cover falls, and at the same time improve the sealing between the cover and the exhaust pipe after the cover falls.

[0013] Preferably, multiple support plates are fixed at equal intervals from top to bottom on both the left and right side walls of the drying chamber, and the lower left and right edges of the carrier frame are placed on the corresponding two support plates. A handle is fixed to the middle of the front side of the carrier frame, which makes it simple and convenient to place the carrier frame in the drying chamber and facilitates its removal later.

[0014] Preferably, the bottom wall of the support frame has multiple through holes at equal intervals to facilitate the passage of hot air, thereby facilitating the drying of the containers placed on the support frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By installing a baffle that moves up and down on the top of the exhaust pipe, during drying, the hot air in the drying chamber lifts the baffle, allowing the hot air to carry away the moisture. After drying, the baffle falls down to cover the port of the exhaust pipe, preventing external dust, impurities, or moisture from entering the drying chamber and ensuring the cleanliness of the drying chamber.

[0017] 2. By setting up a wind and water baffle, the wind and water baffle can disperse the hot air output from the air supply pipe. The hot air is sprayed out through the various ventilation holes on the wind and water baffle, so that the hot air is effectively dispersed in the drying chamber, thereby effectively drying the containers on the support frame.
