It includes.

In the process of using such a food waste disposer, if foreign substances such as bones, spoons, chopsticks, etc. that cannot be pulverized are inserted into the bowl, there is a problem that it may put a strain on the driving device for rotating the blades.

Therefore, it is important to prevent failure or damage of the driving device in advance by detecting the restrained state of the driving device.

Normally, in order to determine whether the driving device of a food waste disposer is locked, the current value output from the driving device is used, and when a current value lower than the preset reference current value is measured, it is judged to be locked, but in a low voltage situation, it is actually locked. Even though it is in a normal state, there may be cases where a current value lower than the reference current value is measured and misjudged as a restraint.

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 using a heating element such as an electric heater. Alternatively, 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 ( 50) may be positioned to face the communication port 141 when mounted on the ball receiving portion 12.

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 and inlet through which air flows at the front, and accordingly, the outlet and inlet of the evaporator box 451 is the vent hole of the ball 50 mounted on the ball storage portion 12. It can be arranged to face and communicate with each other. 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 (not shown) and outlet (not shown) of the evaporator box 451 may be formed integrally with the vent of the ball 50, but according to a preferred embodiment, each of the inlet and outlet is, It is preferable that it is formed to be divided separately.

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 discharge port 452 is provided on the bottom of the evaporator box 451, and the bottom surface of the evaporator box 451 may have at least one inclined surface inclined downward around the position of the condensate discharge port 452. Accordingly, When condensate generated inside the evaporator box 451 falls to the floor, it is guided to the condensate discharge port 452 along at least one slope and 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.

The food waste disposer 1 is supplied with commercial power from the outside, and generally AC 220V/60Hz power can be applied, but the power environment supplied to the food waste disposer 1 may vary depending on the installation location.

Therefore, as shown in FIG. 15, the storage unit can store a plurality of signal logic tables for each input voltage.

Here, the signal logic table is one electrical signal or a set of these that can be output from the driving device 120 at the corresponding input voltage, and is transmitted from the driving device 120 when the driving device 120 operates normally under the corresponding input voltage. It may include electrical signals within the output normal range.

In this way, using a plurality of previously prepared signal logic tables, the control unit 110 can set constraint conditions suitable for the input voltage applied to the food waste disposer 1 and determine the constraint of the driving device 120 based on this. there is.

According to a specific embodiment, the control unit 110 first compares the electrical signal measured from the driving device 120 using any one initially selected or set signal logic table to ensure that the measured electrical signal is within the normal range. Restraint of the driving device 120 can be determined based on whether or not it exists (S20).

In general, when the driving device 120 operates, the current value or electrical signal output from the driving device 120 may be constant regardless of torque change or load change, but when the driving device 120 is constrained, the driving device 120 The current value or electrical signal output from (120) may be lower than the normal value or normal range.

Therefore, according to one embodiment of the present invention, the control unit 110 controls the driving device 120 when the electrical signal measured from the driving device 120 is lower than the value within the normal range of any one initially selected signal logic table. It can be determined that restraint has occurred.

If the control unit 110 according to an embodiment of the present invention determines that a restraint has occurred in the driving device 120, the control unit 110 according to an embodiment of the present invention may output a restraint alarm to the outside. there is.

That is, the control unit 110 can notify the outside of the restraint state of the driving device 120 visually or audibly using various alarm means, and accordingly, the user can respond to the object to be treated inside the ball 50. It is desirable to be able to eliminate the cause of detention.

However, in a voltage environment lower than any one of the initially selected or set signal logic tables, even though the driving device 120 is not actually locked, that is, during normal operation, the normal value of the initially selected signal logic table is Alternatively, the current value or electrical signal measured from the driving device 120 is lower than the normal range, so the control unit 110 may mistakenly determine that the driving device 120 is constrained.

Therefore, when the control unit 110 according to an embodiment of the present invention determines that the driving device 120 is restrained, after the restraint is released, it can re-establish a signal logic table other than the currently selected signal logical table. (S30), it is possible to re-determine whether the driving device 120 is restrained using the current value or electrical signal measured from the driving device 120 based on the re-established signal logic table (S40).

Here, in order for the control unit 110 to re-establish the signal logic table, the restraint of the driving device 120 must be released, and in order for the control unit 110 to determine whether the restraint of the driving device 120 has been released, After 50 is separated from the ball receiving unit 12, it can be determined based on whether the ball 50 has been re-entered into the ball receiving unit 12.

Normally, when the driving device 120 is restricted, the user opens the door 20, removes the ball 50, and then disposes of or removes the foreign matter inside the ball 50 that caused the restriction, and then sees it again. It is installed in payment (12).

Therefore, the control unit according to an embodiment of the present invention determines whether the restraint has been released after the restraint of the driving device 120 occurs when the ball 50 is separated from the ball receiving portion 12. It may be determined that the restraint of the device 120 has been released, and then, when the ball 50 is separated from the ball receiving portion 12 and then mounted again on the ball receiving portion 12, the control unit 110 rereads the signal logic table. can be established. To this end, the control unit 110 can detect whether the ball 50 in the ball storage unit 12 is mounted or detached using various means.

Specifically, as shown in FIG. 17, when the control unit 110 according to an embodiment of the present invention determines that the driving device 120 is restrained, it can first stop the driving device 120 (S31).

Next, the control unit 110 may determine whether the door 20 is opened and the ball 50 has separated from the ball receiving unit 12 (S32), and if it is determined that the ball 50 has been detached from the ball receiving unit 12, Afterwards, when the driving device 120 is restarted (S33), it can be re-established with a signal logic table different from any currently selected signal logic table (S34).

Here, another signal logic table re-established by the control unit 110 may be any other than the currently selected signal logic table, but another signal logic table re-established according to an embodiment of the present invention is the current signal logic table. It may be a low-voltage signal logic table lower than the input voltage corresponding to the table, and more preferably, the control unit 110 sequentially and stepwise selects a low-voltage signal logic table each time the signal logic table is re-established.

This is because, although the actual restraint of the driving device 120 did not occur, it was determined that restraint occurred because the electrical signal measured from the driving device 120 in a low-voltage environment was relatively low, and the relatively low voltage measured from the driving device 120 In order to bring low electrical signals into the normal range, it is desirable to re-establish a low-voltage signal logic table.

For example, as shown in FIG. 15, when the signal logic table initially selected by the control unit 110 is the D signal logic table of 230V, the primary The signal logic table re-established may be the C signal logic table of 220V, and if the control unit 110 still determines that the driving device 120 is constrained, the signal logic table re-established in the next priority may be the B signal logic of 210V. As a table, the signal logic table that is re-established when the control unit 110 determines that the driving device 120 is constrained may be a low-voltage signal logic table sequentially and step by step.

However, the signal logic table re-established by the control unit 110 is a signal logic table corresponding to the lowest input voltage among the plurality of previously prepared signal logic tables, and even in this case, the control unit 110 restrains the driving device 120. When it is determined, the signal logic table corresponding to the highest input voltage can be re-established according to the loop, as shown in FIG. 15, or a failure alarm for the driving device 120 can be output.

Of course, the control unit 110 may re-establish the signal logic table by repeating it once or twice or more according to the loop, but it still determines the restraint of the driving device 120 even though it is re-established by repeating it a predetermined number of times. In this case, a failure alarm for the driving device 120 can be output after that.

Ultimately, when the control unit 110 according to an embodiment of the present invention determines the restraint of the driving device 120 by comparing the electrical signal measured from the driving device 120 with any one initially selected signal logic table, or The process of re-establishing another signal logic table (S30) and then re-determining the restraint of the driving device 120 (S40) can be repeated.

On the other hand, when the control unit 110 erroneously determines that the driving device 120 is locked even though it has not actually been locked, that is, when it determines that the driving device 120 is locked due to a low voltage environment, etc., it re-reads the signal logic table. Although it can be established, it is preferable not to re-establish the signal logic table when the actual driving device 120 is locked.

Even if the control unit 110 normally determines that the driving device 120 is constrained, if the signal logic table is re-established, the subsequent constraint of the driving device 120 may continue to be misjudged, so the normal driving device 120 It is necessary to fix the signal logic table when driving.

Accordingly, the control unit 110 drives the driving device 120 according to a predetermined operation mode, for example, an object processing mode, based on a signal logic table, and the driving device 120 operates in the corresponding operating mode without interruption. When the following operations are completed, the currently selected signal logic table can be fixed.

However, since the power environment applied to the food waste disposer 1 may change due to changes in the installation location of the food waste disposer 1, etc., the control unit 110 blocks the power supply applied to the food waste disposer 1 and turns on a new power source. Upon reapplying, the fixed signal logic table can be released, and one of the plurality of signal logic tables, for example, one initially selected, is selected, and then any one initially selected signal logic is again processed according to steps S10 to S50 of FIG. 14. Tables can be established and/or re-established.

Meanwhile, the control unit 110 according to an embodiment of the present invention may use the electrical signal measured from the driving device 120, as described above, to determine restraint of the driving device 120.

Looking at the specific process by which the control unit 110 determines the restraint of the driving device 120, as shown in FIG. 16, the control unit 110 according to an embodiment of the present invention first determines the restraint of the driving device 120. The load of the driving device 120 can be detected by measuring the electrical signal (S21). Of course, although not shown in the drawing, the driving device 120 may be currently operating.

If the control unit 110 determines that the driving device 120 is not in operation because there is no electrical signal measured from the driving device 120, in other words, the control unit 110 applies a control command to the driving device 120 to operate. However, if there is no electrical signal measured from the driving device 120, damage to the driving device 120 can be determined (S26). That is, the control unit 110 can determine whether the driving device 120 is damaged by using the electrical signal of the driving device 120.

When the control unit 110 determines that the driving device 120 is not damaged, it collects the electrical signals of the driving device 120, compares them with the current signal logic table, and determines that the collected electrical signals are included in the signal logic table. When it is outside the normal range, restraint of the driving device 120 can be determined.

Here, the present invention is not particularly limited, but the control unit 110 may collect electrical signals for a predetermined time, and control the electrical signals collected for a predetermined time by performing an arithmetic average or weighted average (for example, the driving device 120). The weight at the beginning of command application may be relatively lower than the weight at other times), and by comparing this with the current signal logic table, the constraint of the driving device 120 can be determined.

In addition, when collecting the electrical signals of the driving device 120 (S24), the control unit 110 according to a preferred embodiment of the present invention rotates the driving device 120 clockwise (CW) or counterclockwise (S24). A control command can be applied to rotate in CCW (S23), and the resulting electrical signal of the driving device 120 can be collected (S24), and then the restraint of the driving device 120 can be determined. That is, the control unit 110 according to an embodiment of the present invention rotates the driving device 120 in one direction and then uses the electrical signal measured from the driving device 120 to drive in one direction. The control unit 110 can determine whether the driving device 120 is restrained.

If the driving device 120 does not drive according to the control command applied by the control unit 110, that is, if there is no electrical signal measured from the driving device 120, the driving device 120 may be determined to be damaged. (S26), if damage is not determined, the restraint of the driving device 120 can be determined by collecting the electrical signals of the driving device 120.

That is, the control unit 110 according to an embodiment of the present invention can first detect damage to the driving device 120, and if it does not determine that the driving device 120 is damaged, it restrains the driving device 120. You can judge.

The driving device 120 is judged to be damaged when there is no electrical signal measured from the driving device 120 or when the electrical signal measured from the driving device 120 is outside the restraint range for determining the restraint of the driving device 120. As, here, the constraint range may be a range in which a predetermined margin is applied based on the normal range of the signal logic table.

In this way, the control unit 110 according to an embodiment of the present invention can determine the restraint of the driving device 120, and when determining the restraint, re-establishes another signal logic table to re-determine the restraint of the driving device 120. By repeating the process one or more times, a standard for determining whether the driving device 120 is constrained according to the current voltage environment can be established.
