Description

Disinfection cabinet with circulating air duct

Technical Field

The invention relates to a disinfection device, in particular to a disinfection cabinet. Can be applied to the disinfection of tableware.

Background

The existing disinfection cabinet generally uses ultraviolet and ozone combination for sterilization, most of the sterilization lamp tubes simultaneously generate ultraviolet rays and ozone, the ozone diffuses everywhere in the cabinet, and uneven concentration everywhere often exists to influence the sterilization effect.

The washed tableware is placed in the cabinet, needs to be heated and dried, and heating components are generally arranged at the inner bottom of the cabinet to dry the tableware, so that the temperature of each place in the cabinet is uneven, and the drying effect of the tableware is affected.

Some existing disinfection cabinets are not provided with an exhaust fan or are provided with an internal circulation exhaust fan, water on tableware cannot be discharged out of the cabinet after being heated into water vapor, after the heating end temperature is reduced, the water is condensed in the cabinet, and bacteria are easily bred in the cabinet. Some exhaust fans are arranged to exhaust water vapor, so that the cabinet is wet and moldy after a long time.

The existing front exhaust disinfection cabinet is generally provided with an exhaust port at the front part, the exhaust stage is generally a gas with larger humidity and certain heat, and exhausted water vapor directly blows to a human body, so that the exhaust temperature is too high to be scalded or clothes are blown wet.

Kitchen air quality is generally poor, and there is often a smoke smell or off-flavor. The sterilizer is generally arranged below the kitchen range, greasy dirt can be splashed on the ground in front of the sterilizer in the cooking process, so that the sterilizer is greasy and slippery, and peculiar smell can be generated. The negative ions can purify air and remove peculiar smell, but have limited diffusion range, and can realize rapid large-range diffusion by virtue of the action of wind force.

Automatic operation mode: when the first humidity sensor in the cabinet body detects that the humidity exceeds a certain value (for example, 60%), a heating and drying program is automatically started or a heating and drying program is started after disinfection, a panel is closed, a fan is started, and an internal circulation air duct is synchronously started to work; along with the continuous progress of the internal circulation heating, the water vapor content in the gas in the cabinet body is increased, and when the second humidity sensor arranged in the handle detects that the humidity exceeds a certain value (for example, 90% -95%) and is maintained for a certain time (for example, 5 min), the surface of tableware in the cabinet body or liquid water in the cabinet body is fully heated and gasified to become water in the air in the cabinet body, at the moment, the electric push rod starts to act to start a panel, the fan continues to work, the external circulation channel is started, and the external circulation channel is turned on to enter an external circulation exhaust mode; along with the progress of extrinsic cycle, when the internal first humidity transducer of cabinet and the built-in second humidity transducer of handle detect humidity value and all be less than certain numerical value (for example 50%), mark that the internal moisture of cabinet has been discharged fully outward, electric putter resets, and the panel is rotatory to be closed, and stoving heating and exhaust fan all accomplish work.

The fan discharges the moisture in the cabinet through the first air duct, is guided to helical blade by it when flowing through the kuppe, makes impeller subassembly lose static balance and then drives its rotation, and the wind-force field that rotatory impeller subassembly produced is then changed the gas that directly arranges forward into the circumference face rotation perpendicular with its initial flow direction, and the spheroid has the trend or the motion of keeping away from the impeller axle center owing to receive centrifugal force effect and then stretches the elastic rope and lengthen, and bulb and elastic rope combination begin rotatory whipping along with impeller subassembly's rotation to promote impeller subassembly further to lose static balance and accelerate its rotation in order to continuously produce bigger wind-force.

As shown in fig. 4, when the panel is closed to form an internal circulation air duct, the hot and humid air of the first air duct flows through the impeller assembly and is guided to the spiral blades by the guide cover, at the moment, the negative ion generator is simultaneously started to work and is diffused to the vicinity of the outer circumferential surface of the impeller assembly through the through holes, at the moment, negative ions and the hot and humid air discharged from the cabinet body are stirred and mixed, the mixture is fully mixed between every two spiral blades (the rising of humidity and temperature is helpful for the rising of the concentration of the negative ions, the water vapor in the exhaust process is medium-temperature air and has higher humidity, and the rising of the concentration of the negative ions which can be diffused out is promoted near the spiral blades), and the formed wind field blows the mixed air to one end of the air duct rapidly, so that the flow rate of internal circulation in the handle is enhanced, the phenomenon that the internal air in the cabinet body stays too long in the handle is avoided, the air is cooled to generate condensed water, the negative ions enter the cabinet body to be purified and deodorized, and the fresh in the disinfection cabinet is kept; in combination with the illustration of fig. 6, the limiting block is positioned in the limiting sleeve, and the door body is locked.

As shown in FIG. 11, when the panel is moved forward under the action of the electric push rod to form an external circulation air duct, the fan discharges moisture in the cabinet through the first air duct, the moisture and the anions are stirred and mixed at the impeller assembly, the moisture and the anions are uniformly and rapidly diffused to the outside in a circular ring mode of circumferential rotation, the moisture and the heat in the cabinet are prevented from directly blowing the human body, meanwhile, the moisture and the heat are promoted to the concentration of the anions and the effect of a wind field are both such that the anions are rapidly diffused to the kitchen in a larger range, the kitchen air is purified and deodorized, and the moisture and the anions supplement each other. The forward discharged direct exhaust gas drives the disturbance impeller assembly to rotate, so that the forward direct exhaust gas is converted into uniform rotary exhaust gas in the circumferential direction, and direct blowing of people is avoided; the impeller component is internally provided with an anion generator, and the anion generator is mixed with the diffused anions between the spiral blades to become rotary anion gas in the circumferential direction; the exhausted gas is medium-temperature and high-humidity, which is beneficial to the increase of the concentration of negative ions; when the impeller component rotates, the ball head is pulled by centrifugal force to expand the elastic rope, so that the impeller component further loses static balance and can rotate for a longer time. In combination with the illustration of fig. 12, the limiting block is separated from the limiting sleeve, and the door body is unlocked.

The handle inner cavity can realize dual purposes and can be automatically switched: the internal circulation air duct and the external circulation air duct can automatically complete switching according to working conditions, and the air duct is convenient and quick; the humidity conditions in the cabinet body and the handle can be automatically detected, and the working states such as external circulation exhaust, internal circulation disinfection/heating and the like are automatically selected according to the humidity conditions of the cabinet body and the handle, and whether the working or the switching of the internal/external circulation modes is automatically completed; the ozone is uniformly diffused in the disinfection process so as to ensure the disinfection effect of all places; the temperature of each part is uniform in the drying process so as to ensure the tableware drying effect; the water vapor in the cabinet is discharged outwards in a front row mode, so that the problem that the cabinet is wet and moldy due to rear row is avoided.
