Abstract
This invention relates to an electronic vacuum disinfection freezer with fresh-keeping and energy conserving functions. It comprises the box, the vacuum refrigeration system, the vacuum system, the vacuum disinfection system, the chest eliminating pressure system and the electronic control circuit. This freezer has two vacuum chambers; the upper chamber is the vacuum refrigeration chamber, the down chamber is the vacuum disinfection chamber, wherein the vacuum refrigeration system comprises the refrigeration compressor, the electronic thermoregulator, the evaporator, the condenser and the vacuum chamber. The vacuum system controlled by the electronic control circuit uses the vacuum pump to connect to the voltage-stabilized box and the vacuum watch through the vacuum pipe, and connects to the two chambers with the chest eliminating pressure pipe through the single direction valve. The vacuum disinfection and fresh-keeping chamber has an ozone motor for circuit control, the two electronic time devices of the eliminating pressure system control the eliminating pressure magnetic valve in the two chambers separately. Touching the related electronic time device for 3 seconds can eliminate the negative pressure in chamber when opening the chamber door. This invention is only for food freezing at high temperature, and it changes the freeing into the vacuum disinfection with fresh-keeping at low temperature.

Background technology
Conventional refrigerator is the shelf time with freezing antibacterial continuity food, the freezing temperature value that continues is the principal element of refrigerator power consumption, and keeping in cold storage also against the nutrition health science to food, because food internal moisture when freezing congeals into ice, thaw back nutrition and pigment can run off and soft color and luster and the freshness of losing of quality with frozen water.
China's utility model patent 02277508.0 discloses a kind of electronic vacuum sterilization fresh energy-saving refrigerator on October 22nd, 2003, the refrigerator of this structure has vacuum sterilization, function such as fresh-keeping, energy-conservation, but also there is following shortcoming in its design: 1. silica gel dual face seals pad is that face contacts with the cabinet frame, does not reach the required seal request of refrigerator thereby reduced pressure; 2. because the vacuum in the vacuum freezing district has possessed heat insulation factor, vacuum heat-insulating layer belongs to design iterations; 3. two index pressure valve have been run counter to the vertical operation principle of check valve and have not been reached seal request in indoor horizontal installation; 4. the charge valve of cabinet catch does not reach seal request because of the vertical operation principle of having run counter to check valve laterally is installed.
Summary of the invention
The object of the present invention is to provide a kind of electronic vacuum sterilization fresh energy-saving refrigerator of good sealing effect.
The objective of the invention is to realize: electronic vacuum sterilization fresh energy-saving refrigerator by following approach, it is made up of disappear pressing system and electronic control circuit of casing, vacuum refrigeration system, evacuation system, vacuum sterilization system, case chamber, it is characterized in that: casing is a double-layer vacuum case cell structure, chamber is the vacuum freezing chamber on it, following chamber is the vacuum sterilization fresh-keeping chamber, and the silica gel door packing and the taper inner-tube mouth of the chamber door of casing is that line contacts design; Vacuum refrigeration system is by electronic temperature control device control refrigeration compressor, and refrigeration compressor is formed vacuum refrigeration system through the condenser tipping indoor evaporimeter of vacuum freezing; The evacuation system of being controlled by electronic control circuit is to connect pressurizer tank and vacuum meter by vavuum pump through evacuation tube, connects the vacuum freezing chamber through check valve with the pressure pipe of finding time to disappear again, and pressure pipe connects the vacuum sterilization fresh-keeping chamber with finding time to disappear; The ozone generator of being controlled by electronic control circuit is installed within the vacuum sterilization fresh-keeping chamber, and forms the vacuum sterilization system with the vacuum tank chamber; The case chamber pressing system that disappears is by electronic timer control magnetic valve, and the pressure pipe that disappears through finding time connects the vacuum sterilization fresh-keeping chamber, electronic timer control magnetic valve, and the pressure pipe that disappears through finding time connects the vacuum freezing chamber; Electronic control circuit is to connect input circuit meets microswitch SS1 again through output circuit input by time relay KT, the output of microswitch SS1 meets ozone generator WE through the closing of contact, pressure switch KP connects input circuit and meets microswitch SS1 through output circuit again, the input of SS2, microswitch SS1, the output of SS2 is through the input of contact KP1, and the output of contact KP1 is through closing of contact vavuum pump M.The case inner bag is that reinforcement pattern vacuum injection forms.
The vacuum freezing chamber of electronic vacuum sterilization fresh energy-saving refrigerator of the present invention aims at the usefulness of megathermal period food refrigeration.Two compartments refrigeration warm area on the chamber; Following two drawers in chamber are freezing warm areas.The vacuum sterilization fresh-keeping chamber aims at the usefulness of food sterilized antistaling and tableware sterilization, indoor each tool closed state of four drawers.The case chamber disappears, and to press what charge into be pure air.Pure air and outdoor air do not possess concurrent condition in the drawer under having the condition of pressure differential.The present invention reduces rated power with vacuum single chamber refrigeration and improves refrigerating efficiency.Range of application is defined in the megathermal period refrigeration reaches the super energy-conservation purpose of imitating year refrigeration work day to reduce.Vacuum possesses antibacterial, and the constant temperature factor is the natural technical conditions of food fresh keeping.
