Description

Food waste disposer and control method of the food waste disposer {FOOD WASTE DISPOSER AND METHOD FOR THE SAME}

The present invention relates to a food waste disposer and a control method thereof, and more specifically, to a food waste disposer capable of processing food waste so that it can be easily disposed of, and a control method thereof.

Normally, food waste must be collected in a certain amount in a food waste storage bin for a certain period of time and then discharged for separate collection.

However, because food waste discharged from homes and restaurants contains a lot of moisture and emits a foul odor, it is difficult to dispose of it.

In response to this situation, food waste treatment devices that can process food waste have appeared, but most of them are bulky and inconvenient in use, so they are not used in real life.

Accordingly, recent Korean Patent Publication No. 10-2011-0056076, Korean Patent Publication No. 10-2016-0044110, etc. are developing food waste disposers in the form of home appliances that can be used at home, and these food waste disposers are generally Components include a bowl that accommodates materials such as food waste, wings that crush and/or stir the materials inside the bowl, and a heating device that applies heat to dry the materials inside the bowl. It includes.

When a food waste processor treats an object such as food waste contained inside a bowl, high-temperature wet steam may be generated from the object wet by the heating device, and the wet steam is condensed by a dehumidifying device, so that the object becomes moisture. This can be removed and dried.

However, since the food waste processor heats the object to be treated, the temperature of the water vapor generated may vary depending on the moisture content of the object to be treated inside the bowl. The higher the moisture content of the object to be treated, the higher the temperature of the steam generated. Therefore, there is a problem that the high-temperature steam may cause deformation in the surrounding structure of the flow path through which the steam flows.

Accordingly, there is a need for necessary technologies that can solve these problems.

When mounted, the object to be treated inside the ball 50 is dried by the heating plate 13 provided in the main body 10, and the ball 50 is coupled by the driving device 34 provided in the main body 10. By rotating the internal movable blades, the object to be dried can be pulverized and/or stirred through interaction with the fixed blades inside the ball 50.

Below, we will look at each component.

The main body 10 forms the exterior of the food waste disposer 1, and is provided with a ball receiving portion 12 in which the balls 50 are accommodated, and various devices for processing the objects inside the balls 50. It may include a machine room.

An openable door 20 may be provided on one side of the main body 10, preferably on the front side. In this specification, for easy explanation of the present invention, the direction in which the door 20 of the main body 10 is provided is assumed to be forward.

When the door 20 is opened, the ball receiving portion 12 may be exposed to the outside, and the user opens the door 20, installs the ball 50 into the ball receiving portion 12, and then closes the door 20. By doing so, the material to be treated inside the bowl 50 can be treated by the food waste processor 1.

The ball receiving portion 12 is isolated from the outside when the door 20 is closed, and in order to prevent odors caused by the object inside the ball 50 from leaking out when processing the object, the main body 10 ) and the door 20 are in contact with each other, and a sealing member (not shown) is provided so that the ball receiving portion 12 maintains airtightness when the door 20 is closed.

A heating plate 13 may be provided on the bottom of the ball receiving portion 12.

The heating plate 13 is a means of heating the object to be heated, and can apply heat to the ball 50 and/or the object to be treated therein using electricity. The present invention does not specifically limit the method of heating the ball 50 and/or the object to be treated therein, but the heating plate 13 heats the object to be heated by using a heating element such as an electric heater. It can be heated, or the object to be heated can be heated using an induction method using induction heating.

By the heat applied by the heating plate 13, the object to be treated inside the ball 50 mounted on the ball receiving portion 12 can be heated and dried.

Specifically, high-temperature wet steam can be generated from a wet object to be treated inside the ball 50 by the heating plate 13, and a device for removing moisture by condensing the wet steam to dry the object to be treated is used. It may be provided in a machine room within the main body 10.

Figure 4 is a view showing the front of a food waste disposer with the door omitted according to an embodiment of the present invention, and Figure 5 is a view showing a refrigeration cycle in the machine room of the food waste disposer according to an embodiment of the present invention.

As shown in Figures 4 and 5, the machine room of the main body 10 includes a compressor 48, a condenser 47, an evaporator 45, and a flow control valve ( 46) can be provided. At this time, it is desirable that the machine room is separated from the ball storage portion 12 so that only workers, not users, can access it in the event of a malfunction, and at least some areas of the outer shell of the main body 10 can be opened and closed for repairs, etc. It is desirable to implement it.

In addition, according to an embodiment of the present invention, the interior of the main body 10 may include a ball receiving housing 14 forming the ball receiving portion 12, and when the ball 50 is mounted on the ball receiving portion 12, The ball receiving housing 14 can surround the ball 50 together with the door 20.

The ball receiving housing 14 may have a rounded shape corresponding to the side of the ball 50 or the container body 51 so that the side can surround the side of the cylindrical ball 50 or the container body 51. .

By the ball receiving housing 14, the ball receiving portion 12 formed inside the ball receiving housing 14 may be separated from the machine room inside the main body 10 outside the ball receiving housing 14. However, the balls 50 are placed inside the ball receiving housing 14. When mounted, the ball receiving housing 14 may have a communication hole 141 formed through one side so that the inside of the ball 50 and a device in the machine room can be connected to each other.

The communication hole 141 formed through the ball-receiving housing 14 may be positioned to face the ventilation hole (not shown) of the ball 50 mounted in the ball-receiving housing 14. As an example, the communication hole 141 may be located toward the front side, that is, towards the door 20 (see FIG. 4), and the ventilation hole of the ball 50 that communicates the inside and outside of the ball 50 with each other is the ball receiving part. When mounted on (12), it can be positioned to face the communication port 141.

Accordingly, when the ball 50 is mounted in the ball receiving housing 14, the ventilation hole of the ball 50 is connected to a device in the machine room (for example, an evaporator) through the communication port 141 of the ball receiving housing 14. They can be connected to each other.

Specifically, on one side of the ball-receiving housing 14, that is, on the rear outer side of the communication port 141 of the ball-receiving housing 14, an evaporator box 451 containing the evaporator 45 may be provided, and at this time, , the opening formed on one side (for example, the front side) of the evaporator box 451 is provided to face the communication opening 141 of the ball receiving housing 14, so that when the ball 50 is installed in the ball receiving housing 14, The inside of the ball 50 may be in communication with the evaporator 45 provided inside the evaporator box 451 through the vent hole of the ball 50 and the communication hole 141 of the ball receiving housing 14.

In this way, in the food waste disposer 1 according to an embodiment of the present invention, the evaporator 45 and the condenser 47, which are heat exchangers, may be provided in different spaces separated by the evaporator box 451. That is, the evaporator box 451 according to an embodiment of the present invention may be a housing that accommodates only the evaporator 45 excluding the condenser 47 inside, and the condenser 47 is located in the machine room outside the evaporator box 451. It can be arranged within me.

The evaporator box 45 accommodates the evaporator 45 in an internal accommodation space, but may be implemented so that the refrigerant can circulate with the compressor 48 and the condenser 47 in the machine room provided outside the evaporator box 45.

By driving the refrigeration cycle, the refrigerant can form a circulating refrigerant flow path (Fr) that sequentially circulates through the compressor 48, the condenser 47, the flow control valve 46, and the evaporator 45. 6 and 7, the high-temperature, high-humidity vapor drawn from the inside of the ball 50 by the circulation fan 44 changes into low-temperature, low-humidity vapor by passing through the evaporator 45, which is a heat exchanger, which A circulating air flow flowing into the inside of the ball 50 can be formed again.

Here, the compressor 48 is located between the evaporator 45 and the condenser 47 on the refrigerant circulation passage (Fr) and can pressurize the refrigerant so that it can circulate along the refrigerant circulation passage (Fr). That is, the compressor 48 can compress the refrigerant discharged from the evaporator 45 and transfer it to the condenser 47.

In addition, the condenser 47 is a means of exchanging heat between the refrigerant transferred from the compressor 48 and the outside air, and the refrigerant passing through the condenser 47 can be condensed by releasing heat to the outside.

Accordingly, as shown in FIGS. 1 to 3, etc., the rear side of the main body 10 may include a plurality of perforated ventilation holes 11 to discharge heat generated from the condenser 47 to the outside. As shown in FIG. 6, etc., at least one heat radiation fan 49 may be provided on one side of the condenser 47 to forcibly exhaust high temperature air inside the machine room to the outside.

As described above, the food waste disposer 1 according to an embodiment of the present invention has an evaporator box 45 so that the vapor inside the balls 50 that have passed through the evaporator 45 is not guided to the condenser 47. You may be blocked.

Meanwhile, a circulation fan 44 may be provided on the rear side of the evaporator box 451 provided on the rear side of the ball receiving housing 14.

As shown in Figures 5 and 6, the ball 50 in the ball receiving housing 14, the evaporator box 451, and the circulation fan 44 can be arranged in series, and the circulation fan 44 is driven. As a result, the vapor inside the ball 50 can pass through the evaporator 45, which is a heat exchanger, and then form an airflow that circulates inside the ball 50 again.

Here, the type of the circulation fan 44 is not particularly limited as long as it forms a circulating air flow, but according to an embodiment of the present invention, the circulation fan 44 may be a centrifugal fan. Reference numeral 441 refers to the fan motor of the circulation fan, and reference numeral 442 refers to the fan housing in which the fan motor is mounted and the impeller is accommodated inside.

This circulation fan 44 may be arranged so that the rotation axis faces the front side, that is, the evaporator 45 or the ball 50, and accordingly, the evaporator box 451 provided axially forward of the rotation axis of the circulation fan 44 Through the intake port, low-temperature, low-humidity vapor that has passed through the evaporator 45 can be inhaled.

The vapor thus sucked in is exhausted through an exhaust duct (not shown) connected to the centrifugal direction of the circulation fan 44 by rotating an impeller provided with a plurality of blades along the circumference at a predetermined distance around the rotation axis of the circulation fan 44. It can be.

That is, the high-temperature, high-humidity vapor containing moisture inside the ball 50 due to heating by the heating plate 13 is driven through the ventilation hole of the ball 50 and the inlet of the evaporator box 451 by driving the circulation fan 44. Through it, it can flow into the evaporator 45 inside the evaporator box 451, and the high-temperature, high-humidity vapor changes into low-temperature, low-humidity vapor as it passes through the evaporator 45, which in turn passes through the circulation fan 44. It is possible to form a circulating air flow path Fa that flows into the ball 50 through the exhaust duct and the evaporator box 451 and then again through the vent hole of the ball 50 (see FIGS. 6 and 7).

According to an embodiment of the present invention, the vent formed on one side of the ball 50 may be a single through hole in which the air inflow path and the air discharge path are integrated.

Correspondingly, the evaporator box 451 may be provided with an outlet through which air flows at the front, and the outlet of the evaporator box 451 faces the ventilation hole of the ball 50 mounted on the ball storage portion 12. It can be arranged to enable mutual communication. Here, the inlet of the evaporator box 451 provides a passage through which the internal air of the ball 50 flows into the inside of the evaporator box 451, and the outlet of the evaporator box 451 is opposite to the inlet of the evaporator box 451. A passage through which internal air is discharged into the inside of the ball 50 may be provided.

The inlet and/or outlet of the evaporator box 451 may be formed to extend to protrude toward the front side, that is, toward the door 20, so as to be interconnected with the vent hole of the ball 50 mounted on the ball receiving portion 12. there is.

That is, according to one embodiment of the present invention, when the ball 50 is mounted on the ball receiving portion 12, the inlet and outlet of the evaporator box 451 may be connected to the ventilation hole of the ball 50. As a specific example, when the ball 50 is mounted on the ball storage unit 12, the inlet and outlet of the evaporator box 451 may be inserted and fitted into the inner peripheral surface of the ventilation hole of the ball 50.

At this time, in order to maintain airtightness between the ball 50 and the evaporator box 451, a packing member such as rubber or silicone may be provided on the inner peripheral surface of the vent hole.

Meanwhile, the inlet and outlet of the evaporator box 451, like the vent hole of the ball 50, may be formed integrally. However, according to one preferred embodiment, the inlet and outlet are preferably formed to be separate. .

At this time, the present invention is not particularly limited, but it is preferable that the inlet of the evaporator box 451 has a larger hole area than the outlet. This is because the air flowing from the ball 50 to the evaporator box 451 is air heated by the heating plate 13 inside the ball 50 and thermally expanded, but it flows from the evaporator box 451 to the ball 50. This is because the flowing air is air cooled and condensed by the evaporator 45.

Meanwhile, as described above, the evaporator box 451 may be provided with an intake port (not shown) formed through a rear portion.

The fan housing 442, which accommodates the circulation fan 44 therein, includes an opening formed on one side (for example, the front side), and the opening of the fan housing 442 faces the intake port of the evaporator box 451. It can be provided.

That is, the intake port of the evaporator box 451 is formed to face the rotation axis of the circulation fan 44 provided on the rear side of the evaporator box 451, so that the evaporator box is driven by the circulation fan 44 in the fan housing 442 ( 451) Air cooled by the internal evaporator 45 can be sucked into the circulation fan 44 through the intake port.

As described above, the low-temperature, low-humidity vapor that has passed through the evaporator 45 is sucked in from the axial front of the rotation axis of the circulation fan 44, and the thus sucked vapor is spaced at a predetermined distance around the rotation axis of the circulation fan 44. The air can be exhausted through an exhaust duct connected to the centrifugal direction of the circulation fan 44 by rotation of an impeller provided with a plurality of blades along the circumference.

Specifically, the fan housing 442, which accommodates the circulation fan 44 therein, may be spaced a predetermined distance from the impeller and may be provided with a guide plate along the circumferential direction. Accordingly, the fan housing 442 may be provided with a guide plate along the circumferential direction by rotating the impeller. The sucked air is given a centrifugal force, and when the air with the centrifugal force rotates in one direction around the rotation axis, the guide plate can guide the air flow.

At this time, one side of the guide plate, for example, a portion of the upper side, is formed with an opening, so that the air rotating and flowing along the inner peripheral surface of the guide plate can exit in the centrifugal direction through the opening of the guide plate by centrifugal force, which allows the guide plate to exit in the centrifugal direction. It can flow along an exhaust duct provided to communicate with the opening.

The present invention is not particularly limited, but a guide plate in the form of a partition may be provided inside the fan housing 442 and an exhaust duct extending from one opening.

Ultimately, the air flowing along the exhaust duct may be introduced into the interior of the evaporator box 451 through an exhaust port provided in front of it, that is, formed on the rear side of the evaporator box 451.

In other words, an intake port through which air is sucked into the circulation fan 44 may be formed through the rear side of the evaporator box 451, and in addition, an exhaust port through which air is discharged from the circulation fan 44 may be formed through.

The intake port of the evaporator box 451 is intended to provide a passage through which the air passing through the evaporator 45 in the evaporator box 451 flows to the circulation fan 44, but the exhaust port is used to provide a passage for the air discharged from the circulation fan 44. To supply the inside of the ball 50, the evaporator box 451 is located at the rear so that the low-temperature, low-humidity vapor flowing in from the exhaust port on the rear side can be supplied directly to the inside of the ball 50. It may include a connecting pipe 456 that connects the exhaust port on the side and the exhaust port on the front side so that they can communicate with each other (see FIG. 4).

That is, the connection pipe 456 is provided to cross the front and rear of the evaporator box 451, so that the exhaust port and the discharge port of the evaporator box 451 can be connected to each other, and thus, the discharged air from the circulation fan 44 Air can be supplied directly into the ball 50 without directly contacting the evaporator 45 in the evaporator box 451.

Here, the shape of the connecting pipe is not particularly limited as long as it is used to connect the exhaust port and the discharge port of the evaporator box 451 so that they can communicate with each other.

Meanwhile, the high-temperature, high-humidity wet steam inside the ball 50 changes into low-temperature, low-humidity steam as it passes through the evaporator 45 inside the evaporator box 45. At this time, condensate generated by cooling is stored in the evaporator box 45. It can be stored inside.

At this time, the evaporator box 45 may include a condensate discharge port 452 so that the condensate stored inside can be discharged naturally or forcibly to the machine room outside the evaporator box 45 or to the outside of the main body 10.

That is, the evaporator 45 is a means of heat exchange between the high-temperature, high-humidity vapor drawn from the inside of the ball 50 along the circulating air passage Fa and the refrigerant flowing along the circulating refrigerant passage Fr. The vapor passing through is cooled, and moisture contained in the vapor when passing through the evaporator 45 can be removed.

The evaporator 45 according to an embodiment of the present invention may be of the pin&tube type, as shown in FIG. 4, in order to expand the contact surface with passing air, but the present invention does not specifically limit the type. .

Since the odor derived from the object to be treated is dissolved in the moisture removed in this way, the control unit according to an embodiment of the present invention continues to drive the circulation fan 44 at a predetermined driving speed to generate heat by the heating plate 13. The internal air of the heated ball 50, that is, high-temperature, high-humidity wet steam, can be repeatedly supplied to the evaporator 45, and accordingly, the evaporator 45 repeatedly condenses the high-temperature, high-humidity wet steam, thereby forming the inside of the evaporator box 451. It is desirable to concentrate the odor in the condensate generated from the .

Here, the control unit is a means of controlling the overall operation of the food waste disposer 1, and may include a control unit for executing various application programs in conjunction with each component of the food waste disposer 1 and performing operations related thereto. there is. Specifically, the control unit heats the object to be processed inside the bowl 50 by processing various signals or data input and output through the components of the food waste disposer 1, or by running an application program stored in the storage unit. Various operations of the food waste disposer 1 can be performed or controlled according to various embodiments, such as removing moisture from the object to be treated by driving a refrigeration cycle.

In addition, the control unit according to an embodiment of the present invention continues to operate the circulation fan 44 even after the drying process for the inside of the ball 50 is completed to supply air cooled by the evaporator 45. It is desirable to supply it to the inside of the ball 50 to cool it.

This is because, even if the inside of the ball 50 is dried, the inside of the ball 50 may still have a high temperature atmosphere due to heating by the heating plate 13, which causes the ball 50 to be pulled out from the main body 10. This is because there is a problem that may cause burns to the user.

Therefore, even after drying of the inside of the ball 50 is completed, the control unit continues to operate the circulation fan 44 as well as preferably the refrigeration cycle to cool the inside of the ball 50. It is desirable to do so.

However, in order to allow the user to process the remaining treated material that has been completed inside the ball 50 in a short time, the control unit controls the driving speed of the circulation fan 44 after drying of the inside of the ball 50 is completed. can be higher than the driving speed in the drying stroke, and the driving speed of the compressor 48 can also be higher than the driving speed in the drying stroke.

Meanwhile, as described above, the high-temperature, high-humidity wet steam inside the ball 50 drawn by the circulation fan 44 condenses inside the evaporator box 451 containing the evaporator 45, and the condensed water It can be stored.

In order to discharge condensate generated inside the evaporator box 451 to the outside of the evaporator box 451, a condensate discharge port (not shown) may be formed through the bottom of the evaporator box 451 according to an embodiment of the present invention. Accordingly, the condensate generated inside the evaporator box 451 can be naturally drained to the outside through the condensate discharge port by its own weight.

A condensate outlet 452 is provided on the bottom of the evaporator box 451, and the bottom of the evaporator box 451 may have at least one inclined surface inclined downward around the position of the condensate outlet 452. Accordingly, When the condensed water generated inside the evaporator box 451 falls to the floor, it is guided to the condensed water outlet 452 along at least one slope, so that it can be drained to the outside of the evaporator box 451.

As shown in FIG. 6, by driving the circulation fan 44, the high-temperature, high-humidity vapor inside the ball 50 changes into low-temperature, low-humidity vapor through the evaporator 45 in the evaporator box 451. Steam may form a circulating airflow that flows back into the ball 50 through the exhaust duct of the fan housing 442 and the connection pipe in the evaporator box 451.

In the process of flowing along the circulating air flow, the moisture and odor inside the ball 50 can be converted into condensate in the evaporator box 451, and the air from which moisture and odor have been removed by the evaporator 45 is returned to the ball 50. ) can be supplied inside.

The condensate generated inside the evaporator box 451, that is, the condensate in which the odor is dissolved, is drained to the outside of the evaporator box 451 through the condensate discharge port 452, as described above. The condensate outlet 452 is connected to communicate with the inside of the condensate tank 80, so the condensate in the evaporator box 451 naturally flows into the condensate tank 80 and can be stored in the condensate tank 80. .

At this time, the condensate tank 80 or the condensate tank inlet is provided at the lower part of the evaporator box 451 or the condensate discharge port 452 of the evaporator box 451, that is, at a relatively low position, so that the condensate generated in the evaporator box 451 It is desirable to allow natural drainage into the condensate tank (80).

Meanwhile, a first ventilation hole may be provided at the upper part of the condensate tank 80 as a passage through which air in the condensate tank 80 is exhausted to the outside.

Although the present invention is not particularly limited, the first ventilation hole may be formed through the upper surface of the condensate tank 80, and specifically, may be formed through the tank cover of the condensate tank 80.

At this time, the first ventilation hole not only provides a passage through which the air in the condensate tank 80 is exhausted to the outside, but also allows external air (for example, the machine room within the main body 10 or air outside the main body 10) to flow in. It can provide a path through which this can happen.

Accordingly, the condensate flowing in through the condensate tank inlet is stored inside the condensate tank 80, but the condensate tank inlet is connected to communicate with the condensate outlet 452 of the evaporator box 451, and the condensate tank 80 is connected to the condensate tank 80. Since the inlet is connected to communicate with the first ventilation hole, the pressure in the circulating air flow (ball 50 - evaporator box 451 - circulation fan 44) generated by driving the circulation fan 44 can be removed. there is.

That is, the inside of the evaporator box 451 is connected to the inside of the condensate tank 80, and external air flows into the condensate tank 80 or the evaporator box 451 through the first ventilation hole formed through the condensate tank 80. ) or, conversely, some of the air in the circulatory airflow may be discharged to the outside, so if a pressure change occurs in the closed circulatory airflow, the pressure can be removed.

Meanwhile, since the odor generated from the object to be treated is concentrated and dissolved in the condensate, there are few odor-causing substances in some of the air in the circulating air flow discharged to the outside through the first ventilation hole.

However, even if the air containing odor-causing substances is exhausted to the outside, even in a small amount, it may cause discomfort to the user. Therefore, according to an embodiment of the present invention, a deodorizing filter 90 may be connected to the first ventilation hole.

The type of deodorizing filter 90 according to an embodiment of the present invention is not particularly limited as long as it can adsorb and remove bad odors in the air, but for example, it may be a filter containing an adsorbent made of activated carbon, or a filled type ( It may be in powder type or powder type, etc.) or block type, but may be a combination of one or two or more types of filters.

However, the block-type filter is formed by compressing a powder-type filter by heat and pressure. Rather than a filled filter in which air escapes between the powders and the filter function deteriorates, the deodorizing filter 90 according to a preferred embodiment is a block-type filter. It could be a type filter.

This is because, according to one embodiment of the present invention, the flow rate of air flowing through the deodorizing filter 90 is small, so it is desirable to use a block-type filter with relatively excellent filtration performance.

This deodorizing filter 90 is provided to be detachable and replaceable in cases where the deodorizing ability is reduced or the expiration date has expired, but is located in a position within the main body 10 that can be easily accessed by a user or worker, for example, the main body ( It can be located in front of 10).

Accordingly, the user or worker can remove the part of the outer shell of the main body 10 that corresponds to the deodorizing filter 90, remove the existing deodorizing filter 90, and install a new deodorizing filter 90.

To this end, an exhaust pipe 91 may be provided to form a path through which air flows between the first ventilation hole of the condensate tank 80 and the front deodorizing filter 90. That is, one end of the exhaust pipe 91 may be connected to the first ventilation hole, and the other end of the exhaust pipe 91 may be connected to the deodorizing filter 90.

Ultimately, some of the air in the circulating airflow circulating between the ball 50, the evaporator box 451, and the circulation fan 44 is transferred from the evaporator box 451 to the condensate tank 80, as shown in FIG. And the condensate is discharged to the outside along the exhaust pipe 91 through the first ventilation hole of the exhaust tank 80. At this time, it is discharged to the outside through the deodorizing filter 90 located at the end of the exhaust pipe 91, thereby eliminating the odor in the discharged air. Not only can the causing substances be adsorbed and removed, but the pressure generated in the closed circulation passage can thereby be removed.

Specifically, when the air inside the ball 50 is heated by the heating plate 13, a positive pressure atmosphere can be formed in the circulating air flow, and accordingly, some of the air in the circulating air flow flows into the first ventilation hole of the condensate tank 80. By being discharged to the outside of the main body 10 through the exhaust pipe 91 and the deodorizing filter 90 connected to , the positive pressure in the circulation passage can be removed.

On the contrary, as shown in FIG. 6, outside air may be provided to the condensate tank 80 or the evaporator box 451 through the first ventilation hole along the exhaust pipe 91 through the deodorizing filter 90. When negative pressure occurs in a closed circulation passage, that pressure can be removed.

That is, the air in the circulation passage is cooled and condensed by the evaporator 45 to form a negative pressure atmosphere in the closed circulation passage, and the interior of the condensate tank 80 is also created with a negative pressure atmosphere by driving the discharge motor 85. may be formed, and as a result, outside air may be introduced through the deodorizing filter 90. The external air introduced through the deodorizing filter 90 flows into the evaporator box 451 or the condensate tank 80 through the exhaust pipe 91 and the first ventilation hole connected thereto, so that the negative pressure in the circulation passage can be removed.

Meanwhile, according to an embodiment of the present invention, an expansion tank 81 is provided between the condensate tank 80 and the deodorizing filter 90 to remove moisture in the air discharged from the condensate tank 80. .

Specifically, the expansion tank 81 may include a communication hole through which air flows in from the outside to the inside, and may also include a second ventilation hole through which air within the expansion tank 81 is discharged to the outside.

Here, the communication hole of the expansion tank 81 can be connected to communicate with the first ventilation hole of the condensate tank 80, and the second ventilation hole of the expansion tank 81 can be connected to communicate with the exhaust pipe 91, The air in the condensate tank 80 may sequentially pass through the first ventilation hole, the communication hole, and the second ventilation hole, and be discharged to the outside through the exhaust pipe 91 and the deodorizing filter 90.

The expansion tank 81 is provided at the upper part of the condensate tank 80, specifically at a position where the communication hole of the expansion tank 81 is higher than the first ventilation hole of the condensate tank 80, and are connected so that they can communicate with each other, so that the condensate tank 81 It is desirable to allow air that does not contain moisture to naturally flow from (80) into the expansion tank (81).

Additionally, the second ventilation hole of the expansion tank 81 may discharge air from which moisture has been removed from the air introduced into the interior through the communication hole.

At this time, the present invention is not particularly limited, but according to an embodiment of the present invention, the second ventilation hole is an expansion tank so that air that does not contain moisture can be discharged through the second ventilation hole of the expansion tank 81. It may be located at the upper part of (81), and on the contrary, the communication hole connected to enable communication with the first ventilation hole of the condensate tank (80) may be located at the lower part of the expansion tank (81).

That is, the air flowing in from the communication hole at the bottom centered on the expansion tank 81 has its moisture removed and can be exhausted through the second ventilation hole at the top, and at this time, the expansion tank 81 removes the air flowing in through the communication hole. In order to remove heavy moisture, a member for dehumidification may be provided inside the expansion tank 81, but according to an embodiment of the present invention, at least one partition for dehumidification is provided inside the expansion tank housing 80. By providing (not shown), moisture in the air introduced into the expansion tank 81 can be removed.

Specifically, the partition wall is provided on the flow path of air flowing from the communication hole in the expansion tank 81 to the second ventilation hole, and may block part of the flow path.

According to one embodiment, the positions of the communication hole provided on the lower side of the expansion tank 81 and the second ventilation hole provided on the upper side are arranged to be staggered with respect to the longitudinal center of the expansion tank 81, and at this time, the communication hole is Between the hole and the second ventilation hole, at least one partition formed downward on the inner upper wall of the expansion tank 81 blocks some of the flow paths when the air introduced through the communication hole is discharged through the second ventilation hole. In this case, the moisture-containing air collides with the partition wall in the process, and the moisture in the air can be separated, dehumidified, and then discharged to the outside through the second ventilation hole.

Ultimately, when the air passing through the inside of the expansion tank 81 flows, the moisture in the air can be removed and dehumidified, and the air applied to the deodorizing filter 90 through the expansion tank 81 is dehumidified accordingly. Because it is in a dried state, the lifespan of the deodorizing filter 90 can be improved.

Meanwhile, as described above, an openable door 20 may be provided in front of the main body 10 according to an embodiment of the present invention.

According to a preferred embodiment, in order to prevent the door 20 from being opened only by a user's physical manipulation, the food waste disposer 1 according to an embodiment of the present invention, as shown in FIG. 1, has a door ( A door open button 60 may be included to receive user input for opening 20).

That is, in order to open the door 20 of the food waste disposer 1, the user may touch or press the door open button 60 in advance, thereby releasing the door 20 from the restrained state. You can. That is, the food waste disposer 1 according to an embodiment of the present invention can prevent the door 20 from being physically opened without user manipulation of the door open button 60.

The present invention is not particularly limited, but since the door 20 is provided in the front of the main body 10, the door open button 60 may be provided to be exposed to the upper outer surface of the main body 10, preferably on the front side. , It is desirable to be located close to the door 20 to promote user convenience.

A circuit board 61 is provided on the upper inner side of the main body 10, so that a user input can be received electronically through an electrically connected door open button 60, or a driving device 72, which will be described later, can be operated accordingly.

Ultimately, when there is a user input to the door open button 60, the control unit operates the driving device 72 or the door open module 70, which will be described later, so that the latch 71 of the door open module 70 opens the door ( By disengaging from the coupler 23 of the door 20, the door 20 can be opened, that is, in an unlocked state.

Figure 8 is a diagram showing a door coupler and a latch fastened to it according to an embodiment of the present invention.

As shown in FIG. 8, as a specific example of the door 20 according to an embodiment of the present invention, a coupler 23 may be formed on the inner surface of the door 20.

The coupler 23 is in the form of a recessed groove on the inner surface of the door 20, and the latch 71 can be inserted into the groove to engage and couple with each other.

The coupler 23 may be located on the inner upper part of the door 20, for example, to correspond to the position of the latch 71. Accordingly, when the door 20 is closed, the latch 71 is connected to the coupler 23. By being inserted into the latch 71 and the coupler 23, the latch 71 and the coupler 23 can be fastened to each other, and by mutual fastening, the door 20 can be maintained in a restrained state so that it cannot be opened only through physical manipulation.

Corresponding to the coupler 23, a latch 71 may be provided on the main body 10 of the food waste disposer 1, and the latch 71 is fastened to the coupler 23 provided on the door 20 to couple them to each other. Or, conversely, the fastening may be released and separated from each other.

The latch 71 provided on the main body 10 may be formed to protrude toward the door 20 at a position corresponding to the coupler 23 of the door 20. For example, the latch 71 may be located on the upper side as a part of the main body 10 exposed when the door 20 is opened.

The latch 71 may be provided on the door opening module 70 fixed to the main body 10. In this case, in addition to the latch 71, a driving device 72 may be installed on the door opening module 70. Accordingly, by the driving device 72 that operates according to the control command generated by the control unit, the latch 71 is released from the coupling with the coupler 23, allowing the restrained door 20 to be released. there is.

Looking at the door opening module 70 in detail, Figure 9 is a structural diagram of the door opening module according to an embodiment of the present invention.

As shown in FIG. 9, the latch 71 provided on the door opening module 70 according to an embodiment of the present invention may be formed to protrude forward toward the door 20, and at this time, the latch 71 is positioned on the left and right. It may have a rotation axis 713 provided to cross in one direction.

The rotation axis 713 is provided at approximately the middle position of the latch 71 provided in the front and rear longitudinal direction, so that the front end of the latch 71 can move in the vertical direction when the latch 71 rotates around the rotation axis 713. That is, the front end of the latch 71 may rise or fall depending on the direction of rotation of the latch 71 around the rotation axis 713.

The present invention is not particularly limited, but according to a preferred embodiment, the latch 71 may have a first coupling end 714 bent upwardly at the front side end, and correspondingly, the coupler 23 has an inner A second coupling end 231 may be formed to be bent downward so as to engage and fasten with the first coupling end 714 of the latch 71 at the upper portion.

The longitudinal cross-section of the first coupling end 714 may have an approximately 'L' shape, and the longitudinal cross-section of the second coupling end 231 may have an approximately 'L' shape. That is, the first coupling end 714 and the second coupling end 231 can be fastened by engaging the upward protruding part of the letter 'ㄴ' and the downward protruding part of the letter 'ㄱ', and when fastened, the door 20 is opened. It may remain closed and confined without being activated.

In addition, the first coupling end 714 of the latch 71 may have a front upper surface inclined backward, and correspondingly, the second coupling end 231 of the coupler 23 is the first coupling end. The bottom surface on the side opposite to the end portion 714 may have a slope inclined forward (inward direction of the coupler 23).

Accordingly, even if the latch 71 is in a substantially horizontal state, entry is possible by moving the inclined surface of the second engaging end 231 along the inclined surface of the first engaging end 714 when the door 20 is closed, Upon completion of entry, the first coupling end 714 of the latch 71 and the second coupling end 231 of the coupler 23 may be engaged and fastened with each other.

Meanwhile, the latch 71 may include a front plate 711 provided in the front around the rotation axis 713 and a rear plate 712 provided in the rear around the rotation axis 713.

At this time, the present invention is not particularly limited, but the front plate 711 and the rear plate 712 may form a step with each other, and the rear plate 712 may be located at a relatively higher position than the front plate 711.

In addition, the rotation axis 713 of the latch 71 may be freely rotatable and rotatably coupled to the housing of the door opening module 70, but at this time, the rear side of the latch 71, that is, the back plate 712, is attached to the housing of the door opening module 70. Elastic means 73 may be combined.

The other rear end of the elastic means 73 is a fixed end, and can be fixedly coupled to the housing of the door opening module 70, for example, and the front end of the elastic means 73 is the rear side of the latch 71, i.e. It can be coupled to the thick plate 712.

Accordingly, the clasp 71 to which no external force is applied can have a predetermined posture, for example, a horizontal posture or a posture capable of being fastened to the coupler 23, by the elastic restoring force of the elastic means 73.

That is, the clasp 71 to which no external force is applied may have a substantially horizontal posture, and accordingly, the second coupling end 231 of the coupler 23 is attached to the first coupling end 714 of the clasp 71. When entering by moving from the front to the rear, the first coupling end 714 of the latch 71 may rotate around the rotation axis 713 and be tilted downward, and the second coupling end 231 may be tilted downward. When entry into the coupling end 714 is completed, the first coupling end 714 of the clasp 71 is elastically restored upward by the elastic means 73, and the first coupling end 714 of the clasp 71 and The second coupling ends 231 of the coupler 23 may be coupled to each other.

Meanwhile, by driving the drive device 72, the link arm 722 coupled to the drive shaft 721 can rotate around the drive shaft 721.

The substantially bar-shaped link arm 722 may be eccentrically coupled to the drive shaft 721 of the drive device 72. That is, one end can be coupled to the drive shaft 721 of the drive device 72, and the other end is a free end and is located at the lower part of the rear side of the latch 71, specifically the lower part of the back plate 712, and the latch ( A pressing portion 723 may be provided to press upward the rear side or the rear plate 712 of 71).

Here, the pressing portion 723 may be, for example, in the shape of a roughly cylindrical bar disposed horizontally, but the present invention is not particularly limited thereto, and as a preferred example, the cross section may be a flat oval or a flat polygon rather than a circle. .

Accordingly, when the drive device 72 is driven according to the control command of the controller, the link arm 722 eccentrically coupled to the drive shaft 721 can rotate, and can freely rotate according to the rotation direction when the link arm 722 rotates. However, the pressurizing portion 723 provided at the other end can rise or fall.

In chain, when the pressing portion 723 rises, the latch 71 rotates around the rotation axis 713, so that the rear side of the latch 71 rises and the first coupling end 714 of the latch 71 falls. Conversely, when the pressurizing portion 723 is lowered, the external force applied to the clasp 71 is removed, and the rear side of the clasp 71 is lowered by the elastic restoring force of the elastic means 73 and the clasp 71 is lowered. As the first coupling end 714 rises, the latch 71 can be in a horizontal state or in a position capable of engaging with the coupler 23.

Ultimately, with the user's manipulation input to the door open button 60, the control unit can lower the first coupling end 714 of the latch 71 by driving the driving device 72, thereby lowering the first coupling end 714 of the latch 71. The latch 71 and the coupler 23 can be separated.

When the latch 71 and the coupler 23 are separated from each other, the door 20 is released, and the user can open the door 20 by flipping the door 20.

On the other hand, if the food waste processor 1 is pulverizing and/or agitating the object to be treated, or if a high temperature atmosphere is formed inside and outside the bowl, it may be dangerous to the user, so the control unit according to an embodiment of the present invention Only when the temperature inside the ball 50 or the ball storage unit 12 is below the safe temperature can release the restraint state of the ball 50, or, as a specific example, release the restraint state of the door 20.

Control method of food waste processor

Meanwhile, Figure 10 is a step-by-step flowchart of a control method for a food waste disposer according to an embodiment of the present invention.

As shown in FIG. 10, the control method of the food waste disposer 1 according to an embodiment of the present invention includes a step (S10) in which the control unit operates the heating plate 13 according to a predetermined operation mode, and the control unit operates the heating plate 13 according to a predetermined operation mode. (50) If it is above the first threshold value set based on the internal temperature, the operation of the heating plate 13 is stopped and the cooling device is operated to cool the air inside the ball 50 (S31 to S32); , the control unit may include a step (S50) of restarting the operation of the heating plate 13 when the air temperature inside the ball 50 is below a preset second threshold value.

In other words, it prevents deformation of the structure due to high-temperature water vapor generated when the food waste processor 1 processes objects containing moisture, and ensures that the food waste processor 1 continues to process the objects normally. can do.

However, the steps shown in FIG. 10 or the steps according to an embodiment of the present invention described above are not essential, and a control method of a food waste disposer may be implemented having more or fewer steps.

Below, we will look at each step in detail.

As described above, the control unit is a means of controlling the overall operation of the food waste disposer 1, and includes the heating plate 13, compressor 48, heat dissipation fan 49, circulation fan 44, heat dissipation fan 49, etc. By generating control commands for components of the same food waste disposer 1 and applying them (or outputting control signals), the operation of the control object can be controlled.

When the food waste disposer 1 operates in a predetermined operation mode according to user input, etc., the control unit may operate various components within the food waste disposer 1 according to the predetermined operation mode (S10). The control unit can generate and transmit control commands to each component to operate each component continuously or discontinuously according to a preset sequence.

Specifically, the control unit has a processing mode for pulverizing and/or agitating the object to be treated, a washing mode for cleaning the inside of the bowl by heating the washing water inside the bowl, or a drying mode for drying the inside of the bowl or wet steam generated from the inside of the bowl. Depending on the combination of at least one of the operation modes such as dry mode, at least one of each component in the food waste disposer 1 may operate simultaneously or at different times according to a preset order.

When the food waste disposer 1 operates according to a predetermined operation mode, the heating plate 13 according to an embodiment of the present invention operates according to a control command by the control unit to dispose of the food to be processed accommodated inside the bowl 50. Garbage can be heated.

When the control unit according to an embodiment of the present invention operates the heating plate 13 to heat the object to be treated, the ball 50 or the object to be treated inside the ball 50 can be heated.

The control unit can heat the ball 50 or the object to be treated therein to the target temperature by operating the heating plate 13 using a duty ratio control method or a PID control method. Here, the target temperature is set to a predetermined operation mode (for example, , processing mode, drying mode, washing mode, etc.).

When the control unit heats the ball 50 or the object to be treated within it using the heating plate 13, the temperature of the water vapor generated may vary depending on the moisture content of the object to be treated inside the ball 50, and in this case, the temperature of the water vapor generated may be different. The higher the water content, the higher the temperature of the steam generated.

When the water vapor flows through the ball 50 and the evaporator box 451 by the circulation fan 44 along the circulating air flow path Fa due to the high temperature water vapor, the evaporator 45 and the circulation fan 44 are Since structural deformation may occur due to high-temperature water vapor, the control unit uses a temperature sensor to activate the heating plate ( 13) operation can be stopped (S31).

The control unit may use a temperature sensor to measure the air temperature inside the ball 50 or the temperature of the circulating air passage (Fa). Here, the placement position of the temperature sensor is not particularly limited, and the temperature sensor is connected to the inside of the ball 50, or a duct connected to communicate with the inside of the ball 50, that is, the inside of the evaporator box 451, or the heating plate. At least one may be provided around or on the surface of (13), or inside the ball receiving portion (12).

However, the temperature sensor according to a preferred embodiment is a duct connected to communicate with the inside of the ball 50, specifically an evaporator box ( 451) can be provided inside.

More preferably, the temperature sensor is located in the evaporator box 451, on the path from the ball 50 to the circulation fan 44 in the circulating air passage Fa, specifically in the connecting pipe 456 in the evaporator box 451. It can be arranged outside.

In this way, when the temperature measured by the temperature sensor overheats above the first threshold, the control unit can stop the operation of the heating plate 13 to prevent deformation of the structure provided around the high-temperature water vapor (S31).

Here, when the food waste disposer 1 according to an embodiment of the present invention operates normally, the temperature range of the circulating air passage Fa may be about 60 to 70 ° C, and the control unit uses the first temperature range to determine whether the control unit is overheated. The threshold may be 85°C, which is higher than the normal temperature range.

Meanwhile, when the temperature is above the first threshold, the control unit stops the operation of the heating plate 13 to stop heating the ball 50 or the object to be heated therein, and then uses a cooling device to heat the ball 50. ) The internal air can be cooled (S32).

Here, the cooling device is a device for cooling the air inside the ball 50, and includes a compressor 48, a condenser 47, an evaporator 45, and flow rate control to condense the wet steam inside the ball 50. It may include a valve 46.

According to a preferred embodiment, the control unit uses a cooling device to lower the air temperature inside the ball 50 or the temperature of the circulating air passage (Fa), and adjusts the driving speed of the circulating fan 44 to the driving speed in a predetermined operation mode. It is desirable to cool it quickly by operating it at a higher level.

When the control unit processes the object to be treated inside the ball 50, it is necessary to continuously drive the circulation fan 44 at a predetermined driving speed to repeatedly supply high temperature and high humidity wet steam to the evaporator 45 to increase dehumidification ability. Preferably, when the high-temperature, high-humidity wet steam is overheated and cooled beyond the first threshold value, the driving speed of the circulation fan 44 is increased to a higher driving speed in a predetermined operation mode or is set to the maximum driving speed to increase the cooling ability of the air. It is desirable to raise it.

For example, the driving speed of the circulation fan 44 in processing mode, drying mode, or washing mode may be 500 RPM, but in step S32, where the air inside the ball 50 is cooled using a cooling device, the driving speed is 2,500 RPM. It can be.

In addition to the circulation fan 44, the control unit also operates the compressor 48 and/or the heat dissipation fan 49 at a higher speed than the operating speed in the processing mode, drying mode, or washing mode in order to quickly lower the temperature. It is desirable to drive it at the highest possible speed.

In addition, according to an embodiment of the present invention, in step S31, the control unit may stop the operation of the heating plate 13 if the temperature is above the first threshold, but at this time, the control unit may stop the operation of the heating plate 13. Even so, it is desirable to maintain the operation of the circulation fan 44, cooling device, and heat dissipation fan 49.

In this way, the control unit maintains the operation of the circulation fan 44, the cooling device, and the heat dissipation fan 49 to cool the air temperature inside the overheated ball 50 as well as the high temperature atmosphere inside the food waste processor 1. It is desirable to do so.

Returning again, if the air temperature inside the ball 50 is below the preset second threshold after the cooling step (S32), the controller may re-operate the heating plate 13 (S50).

Here, the second threshold for restarting the heating plate 13 is the air temperature inside the ball 50 or the temperature of the circulating air passage Fa being within the normal temperature range (for example, about 60 to 70°C). , The present invention is not particularly limited, but for example, the second threshold may be the highest value among the values within the normal temperature range, for example, 70°C.

In this way, the heating plate 13 is restarted so that the food waste disposer 1 can be normally operated in a predetermined operation mode, and the air temperature inside the ball 50 or the temperature of the circulating air passage Fa is maintained within the normal temperature range. It is desirable to make it possible.

Meanwhile, Figure 11 is a step-by-step flowchart of a control method for a food waste disposer according to another embodiment of the present invention.

As shown in FIG. 11, the control unit according to another embodiment of the present invention can determine whether the compressor 48 is overloaded.

The control unit may operate various components in the food waste disposer 1 including the heating plate 13 according to a predetermined operation mode, and at this time, the control unit may determine whether the compressor 48 is overloaded (S15).

Specifically, the control unit can detect the temperature of the refrigerant discharged from the compressor 48 using a refrigerant temperature measurement sensor (not shown), and determines whether the temperature of the refrigerant discharged from the compressor 48 is above a preset temperature. The overload of the compressor 48 can be determined.

According to another embodiment of the present invention, even when the control unit determines that the compressor 48 is overloaded, the operation of the heating plate 13 can be stopped (S31), and even after that, the inside of the ball 50 is used using a cooling device. can cool the air (S32).

However, unlike the previous embodiment, the control unit according to the present embodiment operates the heating plate 13 even if the air temperature inside the ball 50 or the temperature of the circulating air passage Fa falls below the second threshold due to the operation of the cooling device. Additional cooling can be done using a cooling device without restarting (S50).

At this time, since the cooling step (S32) using the cooling device and the additional cooling step (S50) are subsequent processes made by determining overheating of the compressor 48, the driving speed of the compressor 48 in S32 and S50 is the compressor Instead of overloading (48), the driving speed of the compressor (48) in the cooling step (S32) of the previous embodiment may be lower or the lowest driving RPM.

As a result of the operation of the compressor 48 in the additional cooling step (S50), the air temperature inside the ball 50 or the temperature of the circulating air passage Fa may gradually decrease over time and fall below the second threshold value. Alternatively, even if the compressor 48 is not operating, the temperature may be gradually lowered by ambient air at room temperature over time.

According to a specific embodiment, the control unit operates the cooling device, specifically the compressor 48, for a predetermined time (for example, 20 minutes) in the additional cooling step (S50) (S61) to reduce the temperature to below the second threshold value. Alternatively, it may be determined whether the temperature is below the third threshold (S62) and the compressor 48 may be operated until the temperature is below the third threshold. Of course, here, the third threshold may be a lower temperature value than the second threshold.

This additional cooling step (S50) is performed to lower the temperature of the ball 50 because there are problems such as causing burns to the user when the ball 50 is pulled out of the main body 10 while the ball 50 is heated. It is to lower it.

Therefore, until the additional cooling step (S50) is completed, the control unit restrains the door 20 so that the balls 50 are not withdrawn from the ball storage unit 12, and when the additional cooling step (S50) is completed, the door 20 is closed. It is desirable to release the restraint (S70).

That is, after stopping the operation of the heating plate 13 (S31) when the compressor 48 is overloaded, the control unit according to an embodiment of the present invention controls the temperature of the air inside the ball 50 or the temperature of the circulating air passage (Fa). If does not reach below the third threshold or fails to operate the cooling device for a predetermined period of time below the second threshold, it may be determined that the ball is not in a state where ball withdrawal is possible, and the control unit determines that the state is in a state where ball can be withdrawn. When this is done, the door 20 or the ball 50 can be released.

That is, the control unit operates the cooling device or compressor 48 for a predetermined time (S61) after the air temperature inside the ball 50 or the temperature of the circulating air passage Fa falls below the second threshold value, or When is below the third threshold value, the restraint of the door 20 or the ball 50 can be released.

The present invention does not specifically limit the method for restraining the ball 50 in the ball storage unit 12 or releasing the restraint of the ball 50, but the control unit according to an embodiment of the present invention uses the door 20. The ball 50 can be restrained by maintaining the closed state, or the ball 50 can be released by releasing the closed state of the door 20 so that it can be opened.

According to a specific embodiment, the control unit binds the latch 71 to the door 20 to restrain the ball 50 in the ball storage unit 12, or, conversely, restrains the ball 50 in the ball storage unit 12. In order to release the door 20, the door 20 can be opened by driving the driving device 72 that operates the latch 71.

That is, the control unit according to an embodiment of the present invention determines that the door 20 is restrained in order to restrain the ball 50 in the ball storage unit 12 if the ball is not in a state in which the ball can be withdrawn even if there is a user input such as a door opening input. A closing command to close the door can be transmitted to the driving device 72 to maintain the state, and when the ball withdrawal is possible, the door 20 is locked in order to release the ball 50 in the ball storage unit 12. An opening command for opening the door can be transmitted to the driving device 72 to release it.

In this way, when there is a door opening input from the user through the door open button 60, the control unit transmits an opening command to open the door to the driving device 72, etc., thereby controlling the operation of the driving device 72 to open the door 20. It can be opened, but by transmitting a closing command to close the door to the driving device 72, etc., depending on the state in which the ball can be withdrawn, the ball 50 is restrained until the ball 50 in the ball storage portion 12 can be withdrawn. By maintaining the state or the closed state of the door 20, user safety can be promoted.

Meanwhile, in step S20, when the control unit determines whether the air temperature inside the ball 50 or the temperature of the circulating air passage Fa is greater than or equal to the first threshold value, that is, the control unit determines whether the temperature is overheated, It can be determined by whether or not the first threshold value is maintained for a predetermined period of time.

As the heating plate 13 operates, the temperature continues to rise, but the temperature measured by the temperature sensor is the temperature measured over time, as shown in FIG. 12, for reasons such as measurement error of the temperature sensor. The waveform of the graph alternately shows increases and decreases like a sawtooth waveform, but may have an overall trend of increasing over time.

Accordingly, the control unit according to an embodiment of the present invention can determine whether the temperature is overheated based on whether the temperature value measured by the temperature sensor is maintained above the first threshold for a predetermined period of time.

As a specific example, as shown in FIG. 12, the temperature value measured by the temperature sensor may continue to increase over time as the control unit operates the heating plate 13, and at this time, the control unit determines that the temperature is at time t11. Although it may be determined that overheating has occurred as the temperature rises above the preset first threshold, the control unit according to an embodiment of the present invention may determine that overheating has not occurred if the time interval between t11 and t12 is shorter than a preset predetermined time. there is. This is because the temperature value measured by the temperature sensor at time t12 is less than the first threshold.

Likewise, in step S40 and/or step S62, when the control unit determines whether the air temperature inside the ball 50 or the temperature of the circulating air passage Fa is below the second and/or third threshold, that is, In order to determine when the cooling is completed, the control unit may determine whether the cooling is maintained above the second and/or third threshold for a predetermined period of time.

As the cooling device operates, the temperature continues to decrease, but the temperature measured by the temperature sensor is the waveform of the temperature graph measured over time, as shown in FIG. 13, for reasons such as measurement error of the temperature sensor. Like this sawtooth waveform, decreases and increases appear alternately, but may have an overall decreasing trend over time.

Accordingly, the control unit according to an embodiment of the present invention may determine whether cooling is complete based on whether the temperature value measured by the temperature sensor is maintained below the second and/or third threshold for a predetermined period of time.

As a specific example, as shown in FIG. 13, the temperature value measured by the temperature sensor may continue to decrease over time as the control unit operates the cooling device, and in this case, the control unit determines that the temperature is preset at t21. It may be determined that cooling has been completed by dropping below the second and/or third threshold, but the control unit according to an embodiment of the present invention determines that cooling has not been completed if the time interval between t21 and t22 is shorter than a predetermined time. sound can be judged. This is because the temperature value measured by the temperature sensor at time t22 exceeds the second and/or third threshold.
