Abstract
The utility model relates to a vacuum fresh-keeping cabinet with a cabinet body and a cabinet door, wherein, the cabinet body is provided with a vacuum pump and a pressure switch; an electromagnetic valve is arranged in the cabinet door. The switch of the electromagnetic valve is arranged in the handle of the cabinet door. The pressure switch and the switch of the electromagnetic valve are connected in series with the vacuum pump and then are connected with a power source. The utility model has the advantage of simple structure, simple principle, long fresh-keeping time, high fresh-keeping quality and low power consumption. The utility model can be matched with different fresh-keeping cabinets to form vacuum fresh keeping.
Description
The utility model relates to a kind of vacuum fresh-keeping cabinet.
Existing antistaling cabinet (as refrigerator) is owing to be antivacuum, and the food of storage is subject to the atmospheric ozone damage layer, and fresh keeping time is short, and fresh-keeping quality is low, reaches fresh-keeping, the consumption of current height by reducing temperature.
The purpose of this utility model is to overcome the defective of above-mentioned technology, the vacuum fresh-keeping cabinet that provides a kind of fresh-keeping quality height, time length, consumption of current to economize.
The utlity model has cabinet, cabinet door, cabinet is provided with vacuum pump, pressure switch, is provided with electromagnetic valve in the cabinet door, and electromagnetic valve switch is located in the handle of cabinet door, and pressure switch, electromagnetic valve switch and vacuum pump string are established the back power connection.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Fig. 1: present embodiment configuration diagram;
Fig. 2: the electrical schematic diagram of present embodiment.
Present embodiment has cabinet 1 and cabinet door 4, and cabinet 1 is provided with vacuum pump 2, pressure switch 3, is provided with electromagnetic valve 5 in the cabinet door 4, and electromagnetic valve switch 6 is located in the handle 7 of cabinet door; Pressure switch 3, electromagnetic valve switch 6 and vacuum pump 2 strings are established the back power connection.During use, vacuum pump 2 is inhaled into vacuum with the air chamber 8 of cabinet 1, and pressure switch 3 is cut off the vacuum-pump power supply (see figure 2) along with air chamber 8 internal gas pressures reduce, air chamber 8 keeps vacuum state, opens 4 pairs at cabinet door, presses electromagnetic valve switch 6 earlier, by electromagnetic valve 5 air inlet air inlet chambers 8, could open cabinet door 4; When closing cabinet door 4, also press electromagnetic valve switch 6 earlier, (see figure 2) is closed electromagnetic valve 5, and this is right, air chamber 8 internal gas pressures raise, pressure switch 3 bounce-backs reclose the power supply of vacuum pump 2, and vacuum pump work keeps chamber vacuum fresh-keeping, this product can be used with all kinds of antistaling cabinets, forms vacuum freshness retaining.
The utility model is simple in structure, and principle is easy, and after the use, fresh keeping time is long, fresh-keeping quality height, and consumption of current is low.
