If the diner takes the meal away in time, the movable contact of the pressure switch 53 is reset in a rebound manner, at the moment, the controller 3 loses the electric signal, the controller 3 controls the timer 54 to stop working and return to zero, if the diner does not take the meal away in time, after the timer 54 reaches 10 minutes, the timer 54 outputs an electric signal to the controller 3, the controller 3 immediately controls the fan 112 at the position to work, under the action of the fan 112, the air in the air inlet area 9 enters the storage grid 4 through the round holes 114 at the same side, the air in the storage grid 4 enters the air outlet area 10 through the round holes 114 at one side of the air outlet area 10, under the cooperation of the two ventilation holes 113, the air in the air inlet area 9, the storage grid 4 and the air outlet area 10 circularly flow, if the heat preservation effect of the external package of the meal is poor, the meal is easy to lose temperature outwards, so that the temperature of the air in the storage cell 4 also changes synchronously (for example, the temperature of the meal is higher, and the heat dissipation is faster, then the temperature of the air in the storage cell 4 is higher), at this time, under the action of the circulating air flow, the air affected by the meal in the storage cell 4 contacts with the heat sensing element 116, if the temperature of the air in the storage cell 4 is higher, the temperature of the heat sensing element 116 is increased, at this time, the resistance of the heat sensing element 116 is reduced, otherwise, if the temperature of the air in the storage cell 4 is lower, the temperature of the heat sensing element 116 is lower, at this time, the resistance of the heat sensing element 116 is increased, and when the controller 3 receives the electric signal output by the timer 54, the connecting loop of the heat sensing element 116 and the electromagnetic push rod 142 is synchronously connected, at this time, the electromagnetic push rod 142 pushes the insulating movable block 143 to move, when the temperature of the air in the storage cell 4 is higher, because the resistance of the heat sensing element 116 is lower, at this time, the current flowing into the electromagnetic push rod 142 is larger, so the distance that the insulating movable block 143 is pushed is larger, at this time, the area that the flexible shading cloth 144 is stretched and unfolded is larger, the shading area of the ultraviolet disinfection lamp 13 is larger, so the light intensity projected to the photosensitive bar 141 is lower, otherwise, the moving distance of the insulating movable block 143 is smaller, at this time, the light intensity projected to the photosensitive bar 141 is higher, and in normal operation, the controller 3 can start the temperature detector 7, the temperature detector 7 can detect the real-time temperature of the external environment, and convert the temperature into an electric signal, and output the electric signal to the controller 3, for example, the external environment temperature is higher, at this time, the electric signal intensity output by the temperature detector 7 is higher, so the controller 3 can control the power of the ultraviolet disinfection lamp 13 to be higher, at this time, the light intensity emitted by the ultraviolet disinfection lamp 13 is higher, and conversely, the ultraviolet disinfection lamp 13 can not only disinfect the meal environment, but also can disinfect the external environment according to the external environment temperature, the light intensity of the external environment can be changed, and the storage condition can be adjusted and controlled under the conditions that the external environment is different in the temperature, and the temperature can be changed under the conditions of 4:
Firstly, when the external environment temperature is low, if the temperature at the heat sensing element 116 is also low, at this time, the meal temperature in the storage grid 4 is substantially the same as the ambient temperature, therefore, the meal belongs to normal temperature food, so the meal does not need to be kept warm, in this case, because the external environment temperature is low, the light intensity emitted by the ultraviolet sterilizing lamp 13 is reduced, and the meal temperature in the storage grid 4 is also low, so the shielding area of the flexible shielding cloth 144 to the ultraviolet sterilizing lamp 13 is also small, therefore, the light intensity projected to the light sensing strip 141 is proper, the light sensing strip 141 is subjected to the increase of the illumination intensity to synchronously reduce the self resistance, so the current introduced into the first electromagnetic switch 145 and the second electromagnetic switch 146 is sufficiently large, at this time, both the first electromagnetic switch 145 and the second electromagnetic switch 146 are closed, and because the current introduced into the third electromagnetic switch 147 is insufficient, the third electromagnetic switch 147 is not closed, and the controller 3 does not start the work of controlling the temperature in the storage grid 4 under the condition that the second electromagnetic switch 146 is not closed;
Secondly, when the external ambient temperature is low, if the temperature at the heat sensing element 116 is high, at this time, the meal temperature in the storage grid 4 is much higher than the external ambient temperature (the difference between the meal temperature and the ambient temperature is usually above 5 ℃), so that the meal belongs to high-temperature food and needs to be stored at high temperature, in this case, because the external ambient temperature is low, the light intensity emitted by the ultraviolet disinfection lamp 13 is small, and the meal temperature in the storage grid 4 is high, so that the shielding area of the flexible shielding cloth 144 to the ultraviolet disinfection lamp 13 is also large, therefore, the light intensity projected to the light sensing strip 141 is small, so that the resistance of the light sensing strip 141 is high, at this time, the current flowing into the first electromagnetic switch 145 is large enough, the moving contact of the first electromagnetic switch 145 is closed, and because the current flowing into the second electromagnetic switch 146 and the third electromagnetic switch 147 is insufficient, the second electromagnetic switch 146 and the third electromagnetic switch 147 are not closed, and in the case that the controller 3 receives only the closed electrical signal of the first electromagnetic switch 145, the controller 3 starts to heat the storage grid 4;
Third, when the external ambient temperature is higher, if the temperature at the heat sensing element 116 is higher, the meal temperature in the storage compartment 4 is substantially the same as the ambient temperature, the light intensity emitted by the ultraviolet rays is higher, but the area covered by the flexible shade 144 is also larger, so that the light intensity projected to the light sensing strip 141 is proper, in this case, both the first electromagnetic switch 145 and the second electromagnetic switch 146 are closed, the third electromagnetic switch 147 is not closed, and in the case that the second electromagnetic switch 146 is closed, and the third electromagnetic switch 147 is not closed, the controller 3 does not start the temperature control operation in the storage compartment 4;
Fourth, when the external ambient temperature is higher, if the temperature at the heat sensing element 116 is lower, the meal temperature in the storage compartment 4 is much lower than the ambient temperature (the difference between the meal temperature and the ambient temperature is usually above 5 ℃), the light intensity emitted by the ultraviolet rays is higher, but the area covered by the flexible shading cloth 144 is smaller, so that the light intensity projected to the light sensing strip 141 is larger, in this case, the first electromagnetic switch 145, the second electromagnetic switch 146 and the third electromagnetic switch 147 are closed because the current flowing into the first electromagnetic switch 145, the second electromagnetic switch 146 and the third electromagnetic switch 147 is large enough, and the controller 3 starts the low-temperature heat preservation operation in the storage compartment 4 when the third electromagnetic switch 147 is closed;
When the second situation occurs, that is, the controller 3 only receives the closing electric signal of the first electromagnetic switch 145, the controller 3 controls the heating end 163 of the resistor strip 161 to be connected with the connection loop of the semiconductor refrigeration rod 15 at the storage grid 4 through the conducting ring 162, at this time, the hot end of the semiconductor refrigeration rod 15 is located inside the heat insulation cover 8, at this time, the cold end of the semiconductor refrigeration rod 15 can transfer the heat of the external environment to the inside of the heat insulation cover 8, under the action of the air flowing in the air inlet area 9, the air outlet area 10 and the storage grid 4, the semiconductor refrigeration rod 15 can properly heat the air flowing in the storage grid 4, so that the meal in the storage grid 4 can be heated and kept warm, the excessive loss of the temperature of the meal is avoided, and at the same time, the higher the temperature measured by the heat sensing element 116 is, the greater the moving distance of the insulating movable block 143 is, the heating end 161 is connected with the conducting ring 162 and the connection loop of the semiconductor refrigeration rod 15 is short, at this time, the lower the temperature of the conducting ring 162 and the semiconductor refrigeration rod 15 is higher, the temperature of the semiconductor refrigeration rod 15 is usually higher than the temperature of the semiconductor refrigeration rod 15, and the higher temperature can be regulated and controlled to be higher, for example, the meal temperature can be kept warm to be higher than the meal temperature is 60 ℃ and can be kept warm, and is the temperature is lower than the temperature is normally, and can be kept warm, and is higher, and is the temperature is 60;
When the fourth situation occurs, that is, the controller 3 receives the closing electric signal of the third electromagnetic switch 147, the controller 3 controls the cooling end 164 of the resistor 161 to be connected with the connection loop of the semiconductor refrigeration rod 15 at the storage grid 4 through the conducting ring 162, at this time, the cold end of the semiconductor refrigeration rod 15 is located inside the heat insulation cover 8, at this time, the cold end of the semiconductor refrigeration rod 15 can transfer the heat inside the heat insulation cover 8 to the outside, so as to refrigerate the inside of the storage grid 4, so as to perform low-temperature heat preservation on the meal in the storage grid 4, avoid excessive increase of the temperature of the meal, and simultaneously, when the temperature measured by the heat sensing element 116 is lower, the moving distance of the insulating movable block 143 is smaller, so that the length of the cooling end 164 of the resistor 161 connected with the conducting ring 162 and the connection loop of the semiconductor refrigeration rod 15 is shorter, at this time, the cold end of the semiconductor refrigeration rod 15 can transmit the heat inside the heat insulation cover 8 to the outside, so that the cold end of the semiconductor refrigeration rod 15 can automatically keep the meal temperature between the temperature of the meal 4 and the temperature of the meal 4, for example, and the meal temperature of the meal 4 is regulated to be normally kept at 7 ℃ between the temperature of the meal 4 ℃ and the temperature of the meal;
in the working process, the controller 3 starts the air pump 178, when the controller 3 only receives the closing electric signal of the first electromagnetic switch 145, the controller 3 controls the first normally-closed electromagnetic valve 176 inside the right pipe 175 at the storage cell 4 to be opened, when the controller 3 receives the closing electric signal of the third electromagnetic switch 147, the controller 3 controls the first normally-closed electromagnetic valve 176 inside the left pipe 174 at the storage cell 4 to be opened, and when the air pump 178 works, the suction end of the air pump 178 sucks out the air inside the air inlet cavity 171, the left pipes 174 corresponding to the storage cells 4 needing to be refrigerated are all in an opened state, at the moment, the external air flows through the semiconductor refrigeration rods 15 at the side through the ventilation hood 173, and under the action of the external air flow, the heat of the hot ends (namely the ends positioned inside the ventilation hood 173) of the semiconductor refrigeration rods 15 is taken away, therefore, the heat of the hot end of the semiconductor refrigeration rod 15 can be timely reduced, the continuous cooling operation of the semiconductor refrigeration rod 15 on the storage grid 4 is facilitated, the air taking away the heat is sucked into the air pump 178 through the air inlet cavity 171 and enters the air outlet cavity 172 through the air pump 178 and the air pipe 179, the right pipes 175 corresponding to the storage grids 4 needing heating and heat preservation are all in an open state, so the hot air entering the air outlet cavity 172 can be conveyed into the ventilation covers 173 through the right pipes 175 and finally discharged through the vent holes 177 of the ventilation covers 173, the heat of the cold end of the semiconductor refrigeration rod 15 needing heating can be supplemented by the heat generated by the semiconductor refrigeration rod 15 needing cooling, the temperature difference of the two ends of the semiconductor refrigeration rod 15 is maintained, the continuous operation of the semiconductor refrigeration rod 15 can be facilitated, when the number of the first normally closed electromagnetic valves 176 in the left pipe 174 or the right pipe 175 is smaller, the air pressure valves 20 in the pressure holes 19 at the air inlet cavity 171 are opened under the negative pressure of the air pump 178, at the moment, part of the outside air is supplemented into the air inlet cavity through the pressure holes 19, and the air pressure valves 20 in the pressure holes 19 at the air outlet cavity 172 are opened under the high pressure of the air conveyed by the air pump 178, at the moment, part of the air is discharged through the pressure holes 19, so that the normal operation of the air pump 178 is ensured;
after the timer 54 counts 1 hour, if the person does not take the meal in time, the timer 54 outputs an electric signal to the controller 3 again after counting 1 hour, at this time, the controller 3 disconnects the semiconductor refrigeration rod 15 at the storage grid 4 from the connection loop of the resistor 161 and the conducting ring 162, and connects the semiconductor refrigeration rod 15 into the power supply loop of the controller 3 itself, so that the cold end of the semiconductor refrigeration rod 15 is located inside the heat insulation cover 8, and forced refrigeration can be performed in the storage grid 4, and the ultraviolet disinfection lamp 13 is matched to avoid food rot and bacteria breeding;
If people take the meal away in time, after the meal is taken away, under the action of the frame-shaped elastic pad 52, the supporting bottom plate 51 is reset in a rebound mode, at the moment, the movable contact of the pressure switch 53 is reset in a rebound mode, so that the closing electric signal of the pressure switch 53 is small, at the moment, the controller 3 can control the semiconductor refrigeration rod 15 and the ultraviolet disinfection lamp 13 to stop working, and control the fan 112 to continue working for 1 minute, meanwhile, the second normally closed electromagnetic valve 183 and the normally open electromagnetic valve 184 are started, at the moment, air flow entering the air outlet area 10 enters the machine barrel 181 through the connecting pipe 186 and flows back into the storage grid 4 through the separating suction hole 182, and the residual smell of the meal in the air is adsorbed and purified by the adsorption filler 185 when the circulated air passes through the interior of the machine barrel 181, so that the food smell left by the previous meal can be prevented from affecting the next meal storage, and the serial smell among the meals can be avoided;
