Detailed Description

(findings constituting the basis of the present disclosure, etc.)

In the case of the present disclosure, the electrostatic atomization device is provided in the vegetable room, and the vegetables stored in the vegetable room are maintained fresh by the mist generated by the electrostatic atomization device. In addition, the mist circulating in the vegetable compartment is sent to the refrigerating compartment to sterilize and deodorize the refrigerating compartment. Under such circumstances, in view of the need to clean the refrigerating compartment used every day, the utility model has constructed the subject matter of the present disclosure to solve the problem of cleaning the refrigerating compartment.

In the present disclosure, there is provided a refrigerator in which an electrostatic atomization device is provided on a top surface of a refrigerating chamber, and mist generated from the electrostatic atomization device disposed on the top surface of the refrigerating chamber can spread into the refrigerating chamber.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, a detailed description beyond necessity may be omitted.

It should be noted that the drawings and the following description are provided to those skilled in the art for a full understanding of the present disclosure, and are not intended to limit the subject matter recited in the claims.

(embodiment mode 1)

Fig. 1 is a front view of a refrigerator, and fig. 2 is a longitudinal sectional view. First, the overall structure of the refrigerator will be described with reference to fig. 1 and 2.

As shown in fig. 2, the refrigerator 1 of the present embodiment includes a refrigerator main body 2, the refrigerator main body 2 having an opening at the front (left side in the X direction shown in fig. 2), and the refrigerator main body 2 is configured by an outer plate 3 made of metal constituting an outer shell, an inner plate 4 made of a hard resin, and a heat insulator 5 foamed and filled between the outer plate 3 and the inner plate 4. Inside the refrigerator main body 2, a plurality of storage compartments are formed by

heat insulating partitions

6, 7, and 8. Each storage compartment of the refrigerator main body 2 is configured to be openable and closable by a rotary type refrigerator compartment door 9 or a

drawer type door

10, 11, 12, 13 which employs the same heat insulation structure as the refrigerator main body 2.

As shown in fig. 1 and 2, the refrigerating compartment 14 is disposed at the uppermost portion in the refrigerator main body 2. In the example of the present embodiment, inside refrigerator main body 2, switching room 15 capable of switching temperature ranges, ice making room 16 provided side by side with switching room 15, vegetable room 17, and freezing room 18 are disposed. The switching chamber 15 is partitioned in the vertical direction with respect to the refrigerating chamber 14 by the heat insulating partition plate 6, and is disposed below the heat insulating partition plate 6. Ice making chamber 16 is disposed in a heat insulating region on the lateral side of switching chamber 15. Vegetable compartment 17 is partitioned from switching compartment 15 and ice making compartment 16 in the vertical direction by heat insulating partition plate 7, and is disposed below heat insulating partition plate 7. Freezing compartment 18 is partitioned from vegetable compartment 17 in the vertical direction by heat-insulating partition plate 8, and is disposed below heat-insulating partition plate 8.

Inside the refrigerating compartment 14, a plurality of shelves 19 are arranged in a plurality of stages in the vertical direction. A freezer compartment 20 having a cooling temperature range different from that of the refrigerator compartment 14 is disposed below the refrigerator compartment 14.

The refrigerating chamber 14 is a storage chamber for refrigerating and preserving, and specifically, is cooled with a temperature set to about 2 to 3 ℃. The temperature of the freezing chamber 20 in the refrigerating chamber 14 is set to about-3 ℃ suitable for freezing preservation. The temperature of the freezing chamber 20 can be set to a temperature range of approximately 1 ℃ for keeping the temperature fresh.

The vegetable compartment 17 is a storage compartment whose temperature is set to be slightly higher than that of the refrigerating compartment 14, and specifically, is cooled by setting the temperature to 4 to 7 ℃. Since the vegetable compartment 17 becomes high in humidity due to moisture emitted from food items such as vegetables, the food items may be partially supercooled and dew may be condensed. Therefore, by setting the vegetable room 17 to a high temperature, the amount of cooling is reduced to suppress the occurrence of dew condensation due to local supercooling.

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

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

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

The cooler 22, the compressor 25, the heat exchanger (not shown), and a dew condensation preventing pipe (not shown) and a capillary tube (not shown) for preventing dew condensation from adhering to the opening of each chamber are connected in a ring shape to form a refrigeration cycle, and cooling by the cooler 22 is performed by circulation of the refrigerant compressed by the compressor 25.

The cooling fan 23 is provided above the cooler 22. By the forced ventilation of cooling fan 23, a part of the cold air cooled by cooler 22 is supplied to refrigerating room 14 through refrigerating room cold air flow path 26 communicating with cooling room 21 on the downstream side of cooling fan 23. Further, a part of the cold air cooled by cooler 22 is supplied to freezer compartment 18 through freezer cold air duct 27 by the forced ventilation of 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 compartment 17 through a vegetable compartment cold air duct (not shown) to cool each of these compartments.

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

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

Fig. 3 is a longitudinal sectional view of an upper portion of the refrigerating compartment 14. The electrostatic atomization device 29 is provided on the inner panel 4 constituting the inner wall of the refrigerating chamber 14, that is, the top surface portion 28 of the refrigerating chamber 14. The electrostatic atomization device 29 generates a nano-sized negative ion mist in the storage chamber. The electrostatic atomization device 29 includes: an atomizing unit 30 for condensing moisture in the air in the refrigerating compartment 14; and a circuit unit 31 for applying a high voltage to the atomizing unit 30.

The atomizing part 30 includes: an atomizing electrode for generating negative ion mist; and a peltier element as supply means for supplying moisture in the air to the atomizing electrode. Thereby, the peltier element is energized to cool the atomizing electrode of the atomizing unit 30.

Refrigerating room cold air flow path 26 is provided on the rear surface of refrigerating room 14 behind electrostatic atomizing device 29. Cold-storage compartment air-conditioning duct 26 is provided so as to extend from the lower end of cold-storage compartment 14 to a position above shelf 19 at the uppermost portion and below top surface portion 28. Cold-storage compartment air-conditioning duct 26 is provided with a plurality of blow-out ports 26a opening toward top surface portion 28.

The top surface portion 28 is provided with an illumination device 32 made of an LED for illuminating the inside of the refrigerator compartment 14. The lighting device 32 and the electrostatic atomization device 29 are arranged in this order from the front opening side of the refrigerating compartment 14.

Space 33 is formed between electrostatic atomizing device 29 and discharge port 26a of cold air passage 26 in the refrigerating compartment. Electrostatic atomizing device 29 is disposed closer to lighting device 32 than refrigerating compartment cold air flow path 26.

A control board housing portion 35 for housing a control board 34 for controlling the operation of the refrigerator 1 is disposed on the outer panel 3 constituting the top wall of the refrigerator 1. In the example of the present embodiment, the control substrate housing portion 35 is formed by a recessed portion provided on the ceiling wall, and the control substrate 34 is housed in the control substrate housing portion 35.

The electrostatic atomizing device 29 is disposed below the control board 34, which is thinner in thickness on the top surface portion 28 than the front surface opening of the refrigerating compartment 14.

As shown in fig. 4, the electrostatic atomization device 29 includes: a base 36 for fixing the atomizing part 30 and the circuit part 31; and an atomizing cover member 37 for covering the base 36. As shown in fig. 5, an engagement claw 36a is formed on the base 36. As shown in fig. 4, a base member 38 is embedded between the inner panel 4 of the top surface portion 28 of the refrigerating compartment 14 and the heat insulating material 5.

In fig. 4, the base member 38 is integrally formed with: a lighting base portion 38a for holding the LED-mounted substrate 32a of the lighting device 32; and a connector housing portion 38b for housing a connector 60 for connecting the electric wiring of the circuit portion 31 and the control board 34.

As shown in fig. 5, a fixing portion 38c for inserting the fixing base 36 is formed integrally with the base member 38 at the rear of the connector housing portion 38 b.

As shown in fig. 5, the engagement claws 36a of the pedestal 36 penetrate through the holes 28a formed in the inner panel 4 of the top surface portion 28 and engage with the base member 38. An insertion portion 36b (see fig. 4) formed integrally with the base 36 is inserted and held between the base member 38 and the illumination cover member 32b constituting the illumination device 32. Screws are inserted into screw-engaging portions 37a (see fig. 6) provided on cold-storage compartment cold air flow path 26 side of atomizing cover member 37, and atomizing cover member 37, base 36, and base member 38 are fixed.

The base 36 is provided on the top surface portion 28 of the inner panel 4 so as to be inclined with respect to the front-rear direction of the refrigerator 1, i.e., the X direction (horizontal direction) in fig. 2. Specifically, as shown by the broken line in fig. 4, one end portion of base 36 on the refrigerating compartment cold air flow path 26 side (rear side of base 36) is disposed at a position lower than the other end portion of base 36 on the refrigerating compartment door 9 side (front side of base 36). The circuit portion 31 fixed to the base 36 is positioned above the atomizing unit 30, and at least an upper end of the circuit portion 31 is disposed above an upper end of the atomizing unit 30.

The atomizing area 30 is located above the outlet 26a (see fig. 3).

As shown in fig. 4 and 6, the atomizing cover member 37 includes a water reservoir 37 b. Water reservoir 37b is provided vertically below atomizing unit 30 so that water held in atomizing unit 30 does not fall on shelf 19.

A partition wall 37c formed integrally with the atomizing cover member 37 is provided around the circuit portion 31 fixed to the base 36. The partition wall 37c is configured such that the mist and the cold air generated in the atomizing part 30 do not enter the inside of the partition wall 37 c.

As shown in fig. 4, the atomizing cover member 37 is formed to protrude toward the inside of the refrigerator as it goes from the top surface portion 28 toward the uppermost shelf 19 of the refrigerator compartment 14. As shown in fig. 4 and 6, spray outlets 37e formed in multiple stages in the vertical direction are disposed on the side surface portion 37d of the atomizing cover member 37. The atomizing cover member 37 is configured such that the mist can be discharged into the refrigerating chamber 14 by natural convection through the mist discharge port 37 e.

The atomizing opening 37e of the atomizing cover member 37 is formed in a stepped shape such that the position of the atomizing opening 37e is closer to the atomizing unit 30 or the electric circuit unit 31 toward the lower stage. Between the spray outlets 37e adjacent to each other in the up-down direction, a plurality of stages of guide ribs 37f extending in the horizontal direction are formed. This prevents the spray opening 37e from being clogged even if food or the like is placed in front of the atomizing cover member 37.

Therefore, even when food or the like is filled in refrigerating compartment 14, mist can be discharged from mist outlet 37e, and the sterilizing effect in refrigerating compartment 14 can be maintained.

As shown in fig. 4, the lower portion of the atomizing cover member 37 is configured to project downward. The water reservoir 37b is formed in a portion that becomes the bottom surface of the lower portion of the atomizing cover member 37.

The atomizing cover member 37 covers the base 36 disposed obliquely from below, and is disposed so as to incline upward as it goes toward the front opening of the refrigerating compartment 14. Therefore, the spray opening 37e between the guide ribs 37f is difficult to be seen from the user's perspective, and visibility in the refrigerating compartment 14 is improved. Further, by disposing the end portion of the guide rib 37f to be inclined upward, the spray opening 37e is made more difficult to see, and foreign matter can be prevented from being mixed into the spray opening 37 e.

An opening 37g is formed in the atomizing cover member 37 on the side opposite to the outlet port 26 a. An opening 37h is formed in the atomizing cover member 37 on the side not opposed to the outlet port 26 a. The opening area of the opening 37g is smaller than the opening area of the opening 37 h. This prevents the cold air of low humidity near the air outlet 26a from actively entering the atomizing cover member 37.

In the example of the present embodiment, two air outlets 26a are formed in the left-right width direction of refrigerating room cold air flow path 26. In a plan view of refrigerator 1, uppermost air outlet 26a is disposed on both left and right sides so as to be separated from each other, and atomizing unit 30 is disposed between respective extensions of both air outlets 26a in the front-rear direction. In this way, the cold air of low humidity configured to be blown out from the air outlet 26a does not directly hit the atomizing part 30.

The operation of the electrostatic atomization device 29 configured as described above will be described.

As described above, electrostatic atomizing device 29 is provided on top surface 28 of refrigerating room 14 disposed in the upper portion of refrigerator 1. The cold air generated by cooler 22 is forcibly ventilated by cooling fan 23, and is blown out from blow-out port 26b formed between shelves 19 through cold-storage room damper 39 and cold-storage room air-conditioning duct 26. The cold air is also blown out from the plurality of blow-out ports 26a that are opened toward the top surface portion 28 above the uppermost shelf 19. Thereby, the inside of refrigerating room 14 is cooled to a predetermined temperature.

The cold air blown out from air outlet 26a is released into space 33 of refrigerating room 14. Therefore, it is possible to suppress the blown cold air of low humidity from being propagated to the periphery of the atomizing part 30 of the electrostatic atomizing device 29.

In the present embodiment, the atomizing area 30 is disposed between the extensions of the two air outlets 26a formed in the left-right width direction in the front-rear direction. Therefore, it is possible to avoid direct suction of the cold air of low humidity into the atomizing area 30. In the atomizing cover member 37 of the electrostatic atomizing device 29, the opening 37g provided on the side opposite to the blow-out port 26a is formed to have a smaller opening area than the openings provided in other portions. Therefore, the blown-out cold air can be further suppressed from being sent to the atomizing unit 30.

In a state where refrigerating room damper 39 for adjusting the amount of cold air to refrigerating room 14 is closed, electric current is supplied from circuit unit 31 to peltier elements of atomizing unit 30 to cool the atomizing electrodes. By cooling the atomizing electrode, the air in the refrigerating chamber 14 around the atomizing electrode is cooled, and moisture in the air is frozen by the cooling, thereby generating frozen moisture on the atomizing electrode.

Thereafter, the frozen water generated on the atomizing electrode of the atomizing unit 30 is melted, and a high voltage is applied to the atomizing electrode through the circuit unit 31, thereby generating a nano-sized negative ion mist. By discharging the generated negative ion mist from the mist outlet 37e to the refrigerating compartment 14, OH radicals contained in the mist in the refrigerating compartment 14 decompose various odor components. This can improve the sterilization and deodorization effect in refrigerating room 14.

Since the side surface portion 37d of the atomizing cover member 37 is formed to protrude into the refrigerator, the atomizing opening 37e formed in the side surface portion 37d is also disposed at a position protruding into the space in the refrigerator. Therefore, the air in the refrigerator is easily sucked into the atomizing cover member 37.

Therefore, the spray opening 37e functions as a suction opening for sucking moisture contained in the air together with the air inside the refrigerator. That is, when water is generated in the atomizing area 30, the moisture in the air inside the atomizing cover member 37 decreases, but the atomizing outlet 37e serves as a refrigerator inside air intake hole in the atomizing cover member 37. Thereby, the air inside the refrigerator can be continuously sent to the atomizing cover member 37 to replace the air. Therefore, an appropriate mist can be continuously generated in the atomizing area 30.

As shown in fig. 2, the control board 34 is housed in a recessed portion of a control board housing portion 35 provided on the top face wall of the outer panel 3. The electrostatic atomizing device 29 is disposed below the control board 34, which is thinner than the front opening of the refrigerating compartment 14. Therefore, a decrease in humidity around the atomizing area 30 can be suppressed.

As shown in fig. 4, one end of base 36 on the refrigerating room cold air flow path 26 side is disposed lower than the other end on the refrigerating room door 9 side. Therefore, the circuit portion 31 can be disposed above the atomizing portion 30, and mist generated by atomization in the atomizing portion 30 is less likely to enter the circuit portion 31. Therefore, dew condensation in the circuit unit 31 can be suppressed.

Since atomizing unit 30 of base 36 is positioned above air outlet 26a (see fig. 3), the cold air blown out from air outlet 26a can be prevented from directly entering atomizing unit 30. Therefore, the reduction in the humidity of the cold air and the difficulty in water production can be suppressed.

The circuit unit 31 is also positioned above the air outlet 26 a. Therefore, the cool air can be prevented from entering the periphery of the circuit portion 31, and the dew condensation in the circuit portion 31 can be prevented.

In the present embodiment, in the electrostatic atomizer 29, the engaging claw 36a provided on the base 36 for fixing the atomizer 30 and the circuit unit 31 is engaged with the base member 38, and the insertion portion 36b formed integrally with the base 36 is inserted and held between the base member 38 and the illumination cover member 32b constituting the illumination device 32. Then, screws are inserted into screw-engaging portions 37a provided on cold-storage compartment cold air flow path 26 side of atomizing cover member 37, and atomizing cover member 37, base 36, and base member 38 are fixed. Therefore, the electrostatic atomizing device 29 can be fixed to the top surface portion 28 by fastening with one screw, and therefore, the assembling workability can be improved.

The top surface portion 28 to which the electrostatic atomization device 29 is attached may be formed with a concave portion that is concave in the direction of the outer panel 3, and the electrostatic atomization device 29 may be partially embedded in the top surface portion 28. In this way, for example, the storage space of the uppermost shelf 19 of the refrigerating compartment 14 can be secured, and the storage amount of the refrigerating compartment 14 can be increased.

In this case, although the thickness of the ceiling wall of the refrigerator is reduced, the heat insulating performance can be maintained by embedding a vacuum heat insulating material in the ceiling wall, for example.

In the present embodiment, the configuration in which the electrostatic atomizing device 29 is disposed on the top surface portion 28 so that the mist is distributed over the entire refrigerating compartment 14 has been described, and the electrostatic atomizing device may be disposed, for example, at the upper corners of the rear portions of both sides of the refrigerating compartment 14. In this way, by disposing the electrostatic atomizing device 29 at a position where it is difficult for a user to reach and take out food by hand, the space in the refrigerating chamber 14 can be effectively utilized.

Industrial applicability of the invention

According to the present disclosure, by providing the electrostatic atomization device on the top surface of the refrigerating chamber, the mist generated from the electrostatic atomization device can be spread throughout the refrigerating chamber, and sterilization and deodorization of the refrigerating chamber can be effectively enhanced. Therefore, it can be applied to various types and sizes of indirect-cooling type refrigerators, such as home and commercial refrigerators.
