Unit 202 and a high-voltage power source 206 for charging the charging unit 202. The charging unit 202 in this example reduces the particle diameter by electrostatically atomizing the liquid water column 203 ejected from the nozzle 201 by the dielectric charging method at the charging electrode 204, that is, by passing a high-voltage electric field. Then, it is sprayed as water droplets 205 of charged fine particles.

  FIG. 7 shows an example of this. A part of the nozzle 201 is inserted into the cylindrical charging electrode 204, and a high voltage is applied by the high voltage power source 206 using the nozzle 201 as a positive electrode and the charging electrode 204 as a negative electrode. The water droplets 205 of the liquid fine particles ejected from the liquid are charged negatively and electrostatically atomized. Thus, when negatively charged, a negative ion effect can be exhibited.

  In addition, by mixing antioxidants and bactericides such as vitamin C into the liquid, and simultaneously spraying them by electrostatic atomization, the active oxygen staying in the air can be removed by the antioxidants. It can be sterilized with a disinfectant. If a grounded electrostatic adsorption unit (not shown) is installed at the tip of the charging electrode 204, suspended fine particles or the like in the air can be adsorbed and collected by static electricity simultaneously with the liquid water droplet 205. As shown in FIG. 6, when a high voltage is directly applied to the nozzle 201 itself, the nozzle 201 itself can be used as a charging unit, and the deodorant can be directly charged by the nozzle 201 simultaneously with spraying.

As described above, an electrostatic atomization method in which a liquid is charged at a high potential and sprayed toward a counter electrode having a potential difference is one of common atomization methods.

It is installed in the vicinity of the conversion unit 139.

  About the refrigerator 100 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation of the refrigeration cycle will be described. The refrigeration cycle is operated by a signal from a control board (not shown) according to the set temperature in the cabinet, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 109 is condensed to some extent by a condenser (not shown), and further, refrigerant piping ( (Not shown) and the like, while condensing and liquefying while preventing condensation on the refrigerator body, it reaches a capillary tube (not shown). After that, the capillary tube is depressurized while exchanging heat with a suction pipe (not shown) to the compressor 109 to become a low-temperature and low-pressure liquid refrigerant and reaches the cooler 112.

  Here, the low-temperature and low-pressure liquid refrigerant exchanges heat with the air in each storage chamber such as the freezer discharge air passage 141 conveyed by the operation of the cooling fan 113, and the refrigerant in the cooler 112 evaporates. At this time, cool air for cooling each storage chamber in the cooling chamber 110 is generated. The low-temperature cold air is diverted from the cooling fan 113 to the refrigerating room 104, the switching room 105, the ice making room 106, the vegetable room 107, and the freezing room 108 using an air passage or a damper 145, and cooled to the respective target temperature zones.

  The refrigerator compartment 104 is cooled to a target temperature by adjusting the amount of cold air with a damper 145 by a temperature sensor (not shown) provided in the refrigerator compartment 104. In particular, the vegetable compartment 107 is adjusted to 2 ° C. to 7 ° C. by ON / OFF operation such as cold air distribution and heating means (not shown).

  The vegetable compartment 107 cools the refrigerator compartment 104 and then discharges it to the vegetable compartment 107 from the outlet 124 for the vegetable compartment 107 configured in the middle of the refrigerator compartment return air passage 140 for circulating the air to the cooler 112. Then, it flows to the outer peripheries of the upper storage container 120 and the lower storage container 119 and indirectly cools, and then returns to the cooler 112 from the suction port 126 for the vegetable compartment 107 again.

  The heat insulating material 152 has a thinner wall thickness than other portions of a part of the rear partition wall 111 that is a relatively high humidity environment, and in particular, the thickness of the heat insulating material behind the cooling pin 134 is 10 mm or less. Has been. Thereby, the recessed part is comprised in the back surface partition wall 111, and the electrostatic atomizer 131 is attached to this location.

  The discharge air passage 141 of the freezer compartment 108 on the back surface of the cooling pin 134 is generated by the cooler 112 by the operation of the cooling system, and cool air of about −15 to −25 ° C. flows by the cooling fan 113 from the air passage surface. The cooling pin 134 is cooled to, for example, about 0 to −6 ° C. by the heat conduction. At this time, since the cooling pin 134 is a good heat conducting member, it is very easy to transmit cold heat, and the atomizing electrode 135 is also cooled to about 0 to −6 ° C.

  Here, since the vegetable compartment 107 is 2 ° C. to 7 ° C. and is in a relatively high humidity state due to transpiration from vegetables, the atomizing electrode 135 is at or below the dew point temperature. Water is generated and attached.

  A negative voltage side is set on the atomizing electrode 135 to which water droplets adhere and the counter electrode 136 is set on the positive voltage side. A high voltage is generated between the electrodes by the high voltage generator 133 (for example, the atomizing electrode 135 is set to 0 V (GND)) 4 to 10 kV). At this time, corona discharge occurs between the electrodes, and the water droplets condensed at the tip of the atomizing electrode 135 are refined by electrostatic energy, and further, the droplets are charged. Nano-level fine mist with ozone, OH radical, oxygen radical, etc. is generated. The voltage applied between the electrodes is a very high voltage of 4 to 10 kV, but the discharge current value at that time is a few μA level, and the input is a very low input of 0.5 to 1.5 W. .

  When nano-level fine mist generated at the atomizing electrode 135 in this way is sprayed from the atomizing portion 139, an ion wind is generated. At this time, freshly humid air flows into the atomizing unit 139 from the humidity supply port 138, and therefore, it can be continuously sprayed.

  Further, the generated fine mist is sprayed into the lower storage container 119 along the ion wind, and is very diffusible due to very small fine particles, and the fine mist reaches the upper storage container 120. Since the fine mist to be sprayed is generated by high-pressure discharge, it has a negative charge. Among the vegetables that are fruits and vegetables, green vegetable leaves and fruits are also stored in the vegetable room 107, and these fruits and vegetables are more susceptible to wilt due to transpiration or transpiration during storage. The vegetables and fruits stored in the vegetable room 107 usually include those that are slightly deflated by transpiration at the time of purchase return or transpiration during storage, and have a positive charge. Therefore, the atomized mist is easy to gather on the surface of vegetables, and this improves the freshness.

  In addition, nano-level fine mist adhering to the vegetable surface contains a lot of OH radicals and a small amount of ozone, etc., and is effective for sterilization, antibacterial, sterilization, etc. Encourages vegetables to increase nutrients such as vitamin C.

  The refrigerator compartment 104 is controlled by the damper 145 so as to be in the target temperature zone as described above. That is, when the refrigerator compartment 104 is higher than the target temperature, the damper 145 is opened and cooled. In response to the operation, relatively dry air after cooling the refrigerator compartment 104 flows into the vegetable compartment 107 through the return air passage 140 of the refrigerator compartment 104 from the discharge port 124 of the vegetable compartment 107, and cools the vegetable compartment 107. To do.

  At this time, since the cooling pin 134 is constantly cooled by cold air of about −15 to −20 ° C., the atomization electrode may be excessively condensed due to the environment in the vegetable compartment 107. Therefore, using the return air from the relatively dry refrigerator compartment controlled by the damper 145, water droplets excessively condensed on the atomizing electrode 135 are dried, and the atomizing electrode is controlled to be in an atomizable state. .

  FIG. 4 is a functional block diagram of the refrigerator in the first embodiment. FIG. 5 is a flowchart showing the operation of the refrigerator according to the first embodiment of the present invention.

  In FIG. 4, a control device 160 that controls the operation of the electrostatic atomizer 131 drives a power supply circuit 161 that supplies a voltage to the high voltage generation circuit unit 133 of the electrostatic atomizer 131, a control unit 146, and a cooling pin heater. The controller 146 determines the internal temperature detected by the internal voltage detection means 162 and the high voltage circuit determination means that controls the application of the high voltage to the high voltage generation circuit unit 133. Heater for controlling the energization rate of the cooling pin heater by the outside temperature detected by the outside temperature detecting means 163 which controls the damper 145 and the compressor 109 and the temperature setting of each storage chamber set by the operation unit 164 It consists of control means.

  For example, since the humidity in the storage chamber fluctuates due to the behavior of the compressor 109 and the damper 145, the high voltage generation circuit unit 133 is turned on / off in conjunction with the compressor 109 and the damper 145, and the atomization electrode 135 is excessively condensed. When the state is assumed, the cooling pin heater 158 which is a heating unit is energized and heated, and the condensed water adhering to the surface of the atomizing electrode 135 is melted and evaporated to adjust the amount of water of the atomizing electrode 135. When the atomizing electrode 135 is assumed to be in a supercooled state, the cooling pin heater 158 that is a heating unit is energized and heated to adjust the temperature of the atomizing electrode 135.

  About the control apparatus of the refrigerator comprised as mentioned above, the operation | movement is demonstrated using FIG. 4, FIG.

  In FIG. 5, when the refrigerator 100 is turned on and it is determined in step 200 that the internal temperature of the refrigerator compartment 104 detected by the internal temperature detection means 162 is high, the damper 145 is opened in step 201, and in step 200. If it is determined that the internal temperature of the refrigerator compartment 104 detected by the internal temperature detection means 162 is low, the damper 145 is closed in step 202.

  Next, in step 203, a circuit voltage (DC14V) is supplied from the power supply circuit 161 of the control device 160 to the high voltage generation circuit unit 133 of the electrostatic atomizer 131, and the vegetable compartment 107 is cooled to the set temperature, and then the air path. When the damper 145 provided in 140 is operated from open to closed, a high voltage generation signal is output in step 203, and a high voltage is applied to the atomization unit 139 from the high voltage generation circuit unit 133, whereby the atomization electrode The water adhering to 135 is atomized as a nano-level fine mist in the vegetable compartment 107 by a high voltage. Next, when the damper 145 operates from closing to opening, the output of the high voltage generation signal is stopped in step 204.

  As described above, since the damper 145 of the refrigerator compartment 104 located upstream of the vegetable compartment 107 in the cold air passage opens, cold air is introduced into the vegetable compartment via the refrigerator compartment 104. The opening and closing of the damper 145 provided in the upstream air passage is an important timing that is estimated to change the flow of cool air that controls the condensation and drying around the atomizing section 139, and therefore the determination timing setting means is the damper 145. After the vegetable compartment 107 is cooled to the target temperature, when the damper 145 operates from opening to closing, the high voltage generating circuit 133 applies a high voltage to the atomizing electrode 135 and the counter electrode 136 so that the target mist Can be generated.

  Further, when the damper 145 is opened in step 300, in addition to dehumidification by cold air, the atomizing electrode 135 is heated by energizing the cooling pin heater 158, and when the damper 145 is closed, the cooling pin heater 158 is turned off in step 301.

  As described above, the ON / OFF of the cooling pin heater, which is a heating means, is controlled by the opening / closing operation of the damper, thereby promoting the evaporation of adhering water droplets, preventing excessive condensation, and continuously and stably Can be made.

  If it is determined in step 400 that the outside air temperature detected by the outside air temperature detecting means 163 is low, the inside temperature of the freezer compartment 108 detected by the inside temperature detecting means 162 in step 401 determines that the compressor is turned on. If it is determined that the temperature is higher than the temperature, the compressor 109 is turned ON in step 402, and if it is determined in step 401 that the internal temperature of the freezer compartment 108 detected by the internal temperature detection means 162 is lower than the temperature at which the compressor is turned OFF, In step 403, the compressor 109 is turned off. When the compressor 109 stops after the vegetable compartment 107 is cooled to the set temperature, a high voltage generation signal is output in step 404 and a high voltage is applied to the atomization unit 139 from the high voltage generation circuit unit 133. Thus, the water adhering to the atomizing electrode 135 is atomized as a nano-level fine mist in the vegetable compartment 107 by a high voltage. Next, when the compressor 109 is turned from OFF to ON, the output of the high voltage generation signal is stopped in Step 405.

  As described above, when the open time of the damper 145 is short, such as when the outside air temperature is low, it is estimated that the compressor is turned on and off, and the flow of cool air governing the condensation and drying around the atomizing unit 139 is changed. Since it is an important timing, the determination timing setting means is the compressor 109, and when the compressor 109 stops after the vegetable compartment 107 is cooled to the target temperature, the high voltage generation circuit 133 faces the atomizing electrode 135. A high voltage can be applied to the electrode 136 to generate a desired mist.

  Further, when the compressor is ON in step 500, in addition to dehumidification by cold air, the atomizing electrode 135 is heated by energizing the cooling pin heater 158, and when the compressor 109 is OFF, the cooling pin heater 158 is turned OFF in step 406. .

  As described above, the tip of the atomizing electrode during compressor operation is controlled by controlling the ON / OFF of the cooling pin heater, which is a heating means, by the operation of the compressor even when the damper opening time is short, such as when the outside air temperature is low Overcooling can be prevented, the temperature can be controlled appropriately, and atomization can be carried out continuously and stably.

  If the set time has not elapsed since the compressor was turned on in step 600, the cooling pin heater 158 is turned on in step 500, and the set time has passed. In step 601, the cooling pin heater 158 is turned off.

  As described above, when the outside air temperature is low, by controlling the energization of the cooling pin heater according to the time when the atomizer voltage application is turned off, it is possible to prevent overcooling and appropriately control the temperature of the tip of the atomization electrode. it can.

  When it is determined in step 700 that the cooling pin heater 158 is to be turned on, in step 701, the energization rate of the cooling pin heater 158 is determined based on the outside air temperature, and the energization rate is varied depending on the outside air temperature. The energization rate is set to be higher at low outside air, and the energization rate is set to be lower at high outside air.

  As described above, the internal temperature control fluctuates due to fluctuations in the outside air temperature, and the atomization electrode 135 may be supercooled. Therefore, by controlling the energization rate of the cooling pin heater according to the outside air temperature, The temperature at the tip of the atomizing electrode can be appropriately controlled by adjusting the temperature.

  Further, when it is determined in step 700 that the cooling pin heater 158 is to be turned on, the energization rate of the cooling pin heater 158 is determined by the temperature setting of each storage chamber adjusted by the operation unit 164 in step 800, and the energization rate is varied. When the temperature setting is set to a low temperature range, the energization rate is increased, and when the temperature setting is set to a high temperature range, the energization rate is set to be small.

  As described above, the temperature inside the cabinet varies depending on the temperature setting of each storage chamber, and the atomization electrode 135 may be supercooled. Therefore, the conduction rate of the cooling pin heater is controlled by the temperature setting of each storage chamber. Thereby, the temperature of the atomization electrode 135 can be adjusted and the temperature of the atomization electrode front-end | tip can be controlled further appropriately.

  If it is determined in step 900 that the internal temperature of the freezer compartment 108 detected by the internal temperature detection means 162 is not cooled at all, such as when the power is turned on, the atomizer 131 voltage is determined in step 901. Application OFF and cooling pin heater 158 are turned OFF.

  As mentioned above, when the internal temperature is not cooled at all, such as when the power is turned on, condensation or water is not generated on the atomizing electrode, it is in a state where it can not be sprayed, so no unnecessary energization is performed, Power consumption can be reduced.

  As described above, the refrigerator according to the present invention can be applied not only to household or commercial refrigerators or vegetable storage, but also to applications such as low-temperature distribution of food such as vegetables and warehouses.
