(Embodiment 1)
FIG. 1 is a front view of the refrigerator, and FIG. 2 is a vertical sectional view of the refrigerator as viewed from the right side. First, the overall configuration of the refrigerator will be described with reference to FIGS. 1 and 2.

As shown in FIG. 2, the refrigerator 1 according to the present embodiment includes a refrigerator main body 2 having an open front (left side in the X direction shown in FIG. 2). The refrigerator main body 2 is composed of a metal outer plate 3 constituting an outer shell, an inner plate 4 made of hard resin, and a heat insulating material 5 foam-filled between the outer plate 3 and the inner plate 4. .. Inside the refrigerator body 2, a plurality of storage chambers are formed by heat

insulating partition plates

6, 7, and 8. Further, each storage room of the refrigerator main body 2 is configured to be openable and closable by a rotary refrigerating room door 9 or

drawer type doors

10, 11, 12, 13 which adopts the same heat insulating structure as the refrigerator main body 2. Has been done.

In the refrigerator main body 2, as shown in FIGS. 1 and 2, a refrigerating chamber 14 is arranged at the uppermost part. In the example of the present embodiment, in the refrigerator main body 2, a switching chamber 15 capable of switching the temperature zone, an ice making chamber 16 arranged side by side in the switching chamber 15, a vegetable chamber 17, and a freezing chamber 18 are provided. , Are arranged. The switching chamber 15 is vertically partitioned from the refrigerating chamber 14 by the heat insulating partition plate 6 and is arranged below the heat insulating partition plate 6. The ice making chamber 16 is arranged in a heat insulating section next to the switching chamber 15. The vegetable compartment 17 is vertically partitioned from the switching chamber 15 and the ice making chamber 16 by the heat insulating partition plate 7, and is arranged below the heat insulating partition plate 7. The freezing chamber 18 is vertically partitioned from the vegetable compartment 17 by the heat insulating partition plate 8 and is arranged below the heat insulating partition plate 8.

In the refrigerator compartment 14, a plurality of shelf boards 19 are arranged in a plurality of stages in the vertical direction. At the lower part of the refrigerating chamber 14, a partial chamber 20 having a cooling temperature zone different from that of the refrigerating chamber 14 is arranged.

The refrigerating room 14 is a storage room for refrigerating and storing, and specifically, the temperature is set to about 2 to 3 ° C. for cooling. Further, the temperature of the partial chamber 20 provided in the refrigerating chamber 14 is set to about -3 ° C, which is suitable for microfreezing storage. The temperature of the partial chamber 20 can be set even in a chilled temperature zone of around 1 ° C.

The vegetable compartment 17 is a storage chamber whose temperature is set slightly higher than that of the refrigerator compartment 14, and specifically, the temperature is set to 4 to 7 ° C. for cooling. Since the vegetable compartment 17 becomes highly humid due to the moisture emitted from the stored food such as vegetables, dew condensation may occur if it is locally cooled too much. Therefore, by setting the vegetable compartment 17 to a relatively high temperature, the amount of cooling is reduced to suppress the occurrence of dew condensation due to local overcooling.

The freezing chamber 18 is a storage chamber whose temperature is set in the freezing temperature zone, and is usually cooled by setting the temperature to about -18 ° C. However, in order to improve the frozen storage state of the stored food, the temperature may be set to a low temperature such as −30 ° C. or −25 ° C. and cooled.

The switching chamber 15 is a storage chamber in which the temperature inside the refrigerator can be changed, and can be switched from the refrigerating temperature zone to the freezing temperature zone according to the application.

A cooling chamber 21 is arranged on the back surface of the vegetable compartment 17 (on the right side in the X direction in FIG. 2). In the cooling chamber 21, a cooler 22 for generating cold air and a cooling fan 23 for supplying cold air to each chamber are arranged. Below the cooler 22, a defrosting means 24 (hereinafter, referred to as a heater) composed of a glass tube heater or the like is provided.

The cooler 22, the compressor 25, the heat exchanger (not shown), the dew-proof pipe (not shown) that prevents dew from the openings of each chamber, and the capillary tube (not shown). The refrigeration cycle is configured by being connected in an annular shape, and the cooling is performed by the cooler 22 by the circulation of the refrigerant compressed by the compressor 25.

The cooling fan 23 is provided above the cooler 22. A part of the cold air cooled by the cooler 22 is supplied to the refrigerating chamber 14 through the refrigerating chamber cold air passage 26 communicating with the cooling chamber 21 on the downstream side of the cooling fan 23 by forced ventilation by the cooling fan 23. .. Further, a part of the cold air cooled by the cooler 22 is supplied to the freezing chamber 18 through the freezing chamber cold air passage 27 by the forced ventilation of the cooling fan 23. The cold air circulating in the refrigerating chamber 14 or a part of the cold air cooled by the cooler 22 is supplied to the vegetable chamber 17 through the vegetable chamber cold air passage (not shown). In this way, the refrigerator 1 is configured so that each room is cooled.

The heat insulating partition plate 6 that separates the refrigerating chamber 14, the switching chamber 15, and the ice making chamber is provided with a refrigerating chamber damper 39 that adjusts the amount of cold air to the refrigerating chamber 14.

Next, the configuration of the refrigerator compartment 14 will be specifically described.

FIG. 3 is a vertical cross-sectional view of the upper part of the refrigerator compartment 14. FIG. 4 is an enlarged view of the electrostatic atomizing device portion in FIG. 3, and FIG. 5 is a perspective view of the atomizing cover member.

An electrostatic atomizer 29 is provided on the top surface portion 28 of the refrigerating chamber 14, which is an inner plate 4 constituting the inner wall of the refrigerating chamber 14. The electrostatic atomizer 29 generates nano-sized negative ion mist in the storage chamber. The electrostatic atomizing device 29 includes an atomizing unit 30 that condenses moisture in the air in the refrigerating chamber 14, and a circuit unit 31 that applies a high voltage to the atomizing unit 30.

The atomizing unit 30 includes an atomizing electrode 40 that generates negative ion mist and a counter electrode 41 that is arranged so as to face the atomizing electrode 40. A perche element 42 is provided as a supply means for supplying moisture in the air to the atomizing electrode 40. The circuit unit 31 energizes the heat exchange unit Pelche element 42. As a result, heat transfer occurs in the Pelche element 42, and the atomizing electrode 40 is cooled via a cooling unit connected to the endothermic side of the Pelche element 42. Specifically, since the humidity of the refrigerating chamber 14 is a low humidity environment of about 20 to 30%, the atomizing electrode 40 is less likely to condense dew.

Therefore, by increasing the cooling capacity of the atomizing electrode 40 by using the Perche element 42, the moisture in the air is cooled and frozen ice is generated on the atomizing electrode 40. Next, by stopping the energization of the Pelche element 42, the frozen ice is melted on the atomizing electrode 40 and water is generated. Then, a high voltage is applied between the atomizing electrode 40 and the counter electrode 41 via the transformer of the circuit unit 31, and the Pelche element 42 is energized to atomize the generated water and mist. Is configured to generate.

A refrigerating chamber cold air passage 26 is provided behind the electrostatic atomizer 29, that is, on the back surface of the refrigerating chamber 14. The refrigerating chamber cold air passage 26 extends from the lower end portion of the refrigerating chamber 14 to a position above the uppermost shelf board 19 and below the top surface portion 28. The refrigerating chamber cold air passage 26 is provided with a plurality of outlets. Of the outlets provided in the cold air passage 26 of the refrigerating chamber, the outlet 26a provided at the uppermost portion opens toward the top surface 28.

The top surface portion 28 is provided with a lighting device 32 composed of LEDs (light-emitting diodes) that illuminate the inside of the refrigerating chamber 14. The lighting device 32 and the electrostatic atomizing device 29 are arranged in order from the front opening side of the refrigerating chamber 14.

A space 33 is formed between the electrostatic atomizer 29 and the outlet 26a of the refrigerating chamber cold air passage 26. The electrostatic atomizer 29 is arranged closer to the lighting device 32 than the cold air passage 26 in the refrigerator compartment.

A control board storage unit 35 for storing a control board 34 that controls the operation of the refrigerator 1 is arranged on the outer plate 3 that constitutes the top wall of the refrigerator 1. In the example of the present embodiment, the control board storage portion 35 is formed by a recessed portion provided on the top surface wall, and the control board 34 is housed in the control board storage portion 35.

The electrostatic atomizer 29 is arranged below the control board 34 in which the wall thickness of the top surface portion 28 is thinner than the position of the front opening of the refrigerating chamber 14.

As shown in FIG. 4, the atomizing cover member 37 of the electrostatic atomizing device 29 is formed so as to project from the top surface portion 28 toward the uppermost shelf plate 19 of the refrigerating chamber 14 toward the inside of the refrigerator. As shown in FIG. 5, a mist discharge port 37e formed so as to have a plurality of stages in the vertical direction is arranged on the side surface portion 37d of the atomization cover member 37. The atomization cover member 37 is configured so that mist can be discharged into the refrigerating chamber 14 through the mist discharge port 37e. The mist discharge port 37e of the atomization cover member 37 is formed in a stepped shape so that the position of the mist discharge port 37e approaches the atomization portion 30 or the circuit portion 31 toward the lower stage. Guide ribs 37f extending in the horizontal direction are formed between the mist discharge ports 37e adjacent to each other in the vertical direction. As a result, the mist discharge port 37e is prevented from being blocked even if food or the like is placed in front of the atomization cover member 37.

Therefore, even when food or the like is packed in the refrigerator compartment 14, mist can be discharged from the mist discharge port 37e. Various odorous components are decomposed by OH radicals contained in the mist, and the effects of sterilization and deodorization in the refrigerating chamber 14 can be maintained.

As shown in FIG. 4, the bottom surface portion of the atomizing cover member 37 is arranged so as to be inclined upward toward the front opening of the refrigerating chamber 14. Therefore, it is possible to more effectively prevent the mist discharge port 37e from being blocked by food or the like.

The side surface portion 37d of the atomizing cover member 37 is formed so as to project into the refrigerator. Therefore, the mist discharge port 37e formed on the side surface portion 37d is also arranged at a position protruding in the internal space. Therefore, the air in the refrigerator is easily taken into the atomizing cover member 37.

Therefore, the mist discharge port 37e functions as an intake port for taking in the moisture contained in the air together with the air inside the refrigerator. That is, when water is generated in the atomizing section 30, the moisture in the air inside the atomizing cover member 37 decreases, but this mist discharge port 37e serves as an intake hole for taking in the air inside the atomizing cover member 37. By functioning, it is possible to continuously send the air inside the chamber into the atomizing cover member 37 to replace the air. Therefore, an appropriate mist can be continuously generated in the atomizing unit 30. Therefore, various odorous components are decomposed by OH radicals contained in the mist, and the effects of sterilization and deodorization are enhanced.

An opening 37g is formed on the side of the atomizing cover member 37 facing the outlet 26a. An opening 37h is formed on the side of the atomizing cover member 37 that does not face the outlet 26a. The opening area of the opening 37g is smaller than the opening area of the opening 37h. As a result, the low-humidity cold air in the vicinity of the outlet 26a is prevented from positively entering the atomizing cover member 37.

In the example of the present embodiment, two outlets 26a are formed in the left-right width direction of the refrigerating chamber cold air passage 26. In the plan view of the refrigerator 1, the uppermost outlet 26a is distributed and arranged on both the left and right sides so that the atomizing portion 30 is arranged between the extension lines of the two outlets 26a in the front-rear direction. There is. In this way, the low-humidity cold air blown out from the outlet 26a is configured so as not to directly hit the atomizing portion 30.

The operation of the electrostatic atomizer 29 arranged in the refrigerator compartment 14 as described above will be described.

FIG. 6 is a time chart showing the operation of the electrostatic atomizer 29, and is a time chart of the electrostatic atomizer 29 when the temperature detected by the outside air temperature sensor (not shown) installed in the refrigerator 1 is 15 ° C. or higher. The first operation mode is shown.

In the first operation mode, the operation is performed in the order of a freezing mode in which the moisture in the air is frozen on the atomizing electrode 40, a melting mode in which the frozen ice is thawed to generate water, and an atomization mode in which the generated water is atomized. Will be done. As a result, the mist is sprayed onto the refrigerator compartment 14. Each operation mode will be specifically described.

As shown in FIG. 6, when the compressor 25 is in operation, that is, when the compressor is ON (ON), the refrigerating chamber damper 39 is opened (open state), and the outlet 26a passes through the refrigerating chamber cold air passage 26. Cold air is blown into the refrigerator compartment 14.

Then, at a certain point in time, when the indoor temperature sensor (not shown) of the refrigerating chamber 14 reaches a predetermined temperature, a closing signal is input to the refrigerating chamber damper 39 so that the refrigerating chamber damper 39 changes from the open state to the closed state.

Starting from the opening state to the closed state of the refrigerating chamber damper 39, energization of the Pelche element 42 of the electrostatic atomizer 29 is started, and the operation of the freezing mode is performed. In the freezing mode, the perche element 42 is energized and the atomizing electrode 40 is cooled for a predetermined time. At this time, a high current of 1.5 A is applied to the Pelche element 42 to increase the cooling capacity, and the moisture in the air in the refrigerating chamber 14 is frozen by the atomizing electrode 40.

The freezing mode is started when the refrigerator damper 39 is closed. Therefore, the low-temperature, low-humidity cold air heat-exchanged by the cooler 22 is not discharged from the outlet 26a, and the relatively high-humidity air that circulates in the refrigerating chamber 14 and exchanges heat is supplied to the electrostatic atomizer 29. Will be done. That is, while suppressing the decrease in water content, the cooling capacity can be increased by energizing the Pelche element 42 with a high current, and the water content can be continuously frozen on the atomizing electrode 40.

In the case of the example of this embodiment, the operation time of the freezing mode is 10 minutes, and the freezing mode is continued for 10 minutes. This operating time can be changed. The operating time may be changed depending on the load conditions. For example, when there are many stored items in the refrigerating chamber 14, the humidity inside the refrigerator tends to be high, so that the predetermined time, which is the operating time of the freezing mode, may be shortened as compared with the case where there are few stored items.

After the freezing mode is performed for a predetermined time, the operation of the thawing mode is started next. The operating time of the melting mode is 30 seconds in the case of the example of the present embodiment, and the melting mode is continued for 30 seconds. In the melting mode, the energization of the Pelche element 42 is stopped for a predetermined time, and water is generated by melting the frozen ice on the atomizing electrode 40. The melting mode is even more preferably performed with the refrigerator damper 39 closed so that the generated water does not dry out.

After a predetermined time has passed since the melting mode was started, the operation of the atomization mode is started next. In the case of the example of this embodiment, the operation time of the atomization mode is 15 minutes, and the atomization mode is continued for 15 minutes. In the atomization mode, a high voltage is applied between the atomization electrode 40 and the counter electrode 41, and the perche element 42 is also energized. At this time, by energizing the Perche element 42 with a low current of 0.5 A, which is lower than that in the freezing mode, the atomizing electrode 40 is cooled while atomizing to condense moisture in the air. Can be done. Therefore, in the atomization mode, nano-sized negative ion mist can be continuously and quickly sprayed onto the refrigerating chamber 14.

When the Pelche element 42 is not energized during the atomization mode, the heat on the heat dissipation side of the atomization unit 30 is transferred to the endothermic side and the temperature of the atomization electrode 40 rises. Further, the low humidity environment of the refrigerating chamber 14 promotes the evaporation of the water produced in the melting mode. Therefore, sufficient water cannot be retained in the atomizing electrode 40, and there is a possibility that mist cannot be quickly supplied into the refrigerating chamber 14.

As shown in FIG. 6, the refrigerating chamber damper 39 was closed from the start of the operation of the electrostatic atomizer 29 in the freezing mode to the next thaw mode operation and the start of the final atomization mode. It is easier to collect water from the air in the refrigerating chamber 14 than in the case where the refrigerating chamber damper 39 is opened, and mist can be continuously generated more quickly. Depending on the usage status of the refrigerator 1 by the user, even if the refrigerator compartment damper 39 is opened during the operation in each of these modes, the first operation mode of the electrostatic atomizer 29 is not interrupted. Each mode operation is performed.

The first operation mode may be performed every cycle in conjunction with the opening / closing cycle of the refrigerator compartment damper 39. Alternatively, the first operation mode may be performed every two or more predetermined cycles. In the case of the example of the present embodiment, the operation of the first operation mode is performed every two cycles of the opening operation and the closing operation of the refrigerating chamber damper 39, mist is sprayed into the refrigerating chamber 14, and the refrigerating chamber 14 is removed. Bacteria and deodorization are performed.

FIG. 7 is a time chart showing the operation of the electrostatic atomizer 29, and is a time chart of the electrostatic atomizer 29 when the temperature detected by the outside air temperature sensor (not shown) installed in the refrigerator 1 is less than 15 ° C. The second operation mode is shown.

As shown in FIG. 7, when the outside air temperature is lower than 15 ° C., the operating rate of the compressor 25 is low and the load is low. Therefore, the opening rate of the refrigerator damper 39 also decreases. As a result, even if the operation of the compressor 25 is ON, the refrigerator compartment damper 39 is not opened and the closed state is continued, so that the opening / closing operation of the refrigerator compartment damper 39 is not linked to the operation cycle of the compressor 25. There is.

Therefore, when the outside temperature is low, the Pelche element 42 of the electrostatic atomizer 29 is energized starting from the fact that the compressor 25 is turned on from off regardless of the opening / closing operation of the refrigerator damper 39. And execute the freeze mode. In the freezing mode, the Perche element 42 is energized and the atomizing electrode 40 is cooled. At this time, a high current of 1.5 A as a current value is applied to the Pelche element 42 to enhance the cooling capacity, and the moisture in the air in the refrigerating chamber 14 is frozen in the atomizing electrode 40.

As described above, when the outside air temperature is low, the opening rate of the refrigerating chamber damper 39 decreases, and the refrigerating chamber damper 39 often continues to be closed. Therefore, the air in the refrigerating chamber 14 is the air that circulates and exchanges heat in the refrigerating chamber 14, and has a relatively high humidity. Therefore, in the freezing mode, the cooling capacity can be increased by energizing the Pelche element 42 with a high current, and the moisture in the air having a relatively high humidity can be frozen in the atomizing electrode 40. As a result, freezing can be continuously performed while suppressing the decrease in water content in the refrigerating chamber 14.

The freezing mode may be continuously operated for a predetermined time as in the first operation mode, and the predetermined time may be changeable.

The melting mode and the atomization mode are continuously operated for a predetermined time as in the operation in the first operation mode. Depending on the usage conditions, even if the compressor 25 is turned off or the refrigerator damper 39 is opened in the middle of the second operation mode, the second operation mode of the electrostatic atomizer 29 is operated in each mode without interruption. Is done.

The second operation mode may be performed every cycle in conjunction with the off and on operations of the compressor 25. Alternatively, the second operation mode may be operated every two or more predetermined cycles. In the example of the second operation mode shown in FIG. 7, the operation of the second operation mode is performed every two cycles of the operation of the compressor 25, mist is sprayed into the refrigerating chamber 14, and the bacteria in the refrigerating chamber 14 are sterilized. And deodorization is done.

The refrigerating room 14 is provided with a humidity detecting unit 45 that detects the humidity in the room. When the humidity detection unit 45 detects that the humidity is equal to or higher than the predetermined humidity, the energization time to the Pelche element 42 in the freezing mode is subtracted to make it shorter than the predetermined time. As a result, it is possible to prevent the atomizing electrode 40 from being frozen in a state where too much moisture in the air is attached to the atomizing electrode 40 and falling from the atomizing electrode 40 as water droplets when thawed.

When the humidity detected by the humidity detection unit 45 is high humidity, the freezing mode may be stopped so that only the atomization mode is executed. As a result, the mist can be quickly supplied into the refrigerator compartment 14.

In the present embodiment, an example in which the humidity detection unit 45 is installed in the refrigerator compartment 14 has been described. However, the humidity detection unit 45 may be installed on the outside of the refrigerator main body 2 to subtract or stop the operation time of the freezing mode according to the outside air humidity.

Even when the refrigerating chamber door 9 is opened in the freezing mode, the electric power to the perche element 42 may be continued and the operation in the freezing mode may be continued. In this case, since the high humidity outside air enters the refrigerator by opening the refrigerating chamber door 9, it becomes easy to collect the moisture in the air on the atomizing electrode 40.

When the refrigerating chamber door 9 is opened in the atomization mode, the atomization mode operation may be stopped, that is, the energization of the Pelche element 42 and the application of the high voltage may be stopped. Then, when the refrigerating room door 9 is closed, the operation in the atomization mode is restarted, and the operation for the remaining time may be performed. As a result, the mist can be sprayed onto the refrigerating chamber 14 to improve the sterilization and deodorizing performance in the chamber.

As described above, in the refrigerator of the present disclosure, since the atomizing electrode of the electrostatic atomizer is cooled even in the atomization mode, water can be continuously supplied to the atomizing electrode. The mist can be quickly supplied indoors.

In the present disclosure, since the atomizing electrode is cooled even in the atomization mode, water can be continuously supplied to the atomizing electrode, and mist can be quickly supplied to the room. Applicable to refrigerators.
