Description

Food rubbish drying system

It relates to a food waste processing device that allows food waste to be dried up and discarded when food waste is generated.The composition of the food waste processing device for improving drying efficiency during drying and the drying state of food waste are detected to detect the time when drying is completed. It enables automatic operation of the garbage disposal system.

In relation to the food waste treatment apparatus, the applicant has filed the application Nos. 10-2007-0111248 and 10-2008-0003685 and the same principle is applied.

In the conventional food waste treatment apparatus, the food waste treatment device is disposed in the strainer of the sink drain and the soup is separated and administered to the food waste treatment apparatus, and hot air is not evenly transmitted during unstirred drying. Although it can solve the problem of time and power used in the configuration of the stirring device and the stirring device, there were inconveniences in the management of the device configuration, such as difficulty in cleaning and cleaning.

In addition, in the drying time of the processing equipment, the drying state of the food waste is not recognized inside, and the food waste is operated for a certain time regardless of the amount and state of the food waste. There was inconvenience such as letting.

In order to solve the above problems, a drying net having a function of a filtering net and a drying chamber is formed at the drainage strainer of the sink and drying the food waste by allowing hot air to pass from the bottom of the drying net to the top when food waste occurs. The amount of latent heat of evaporation is calculated so that the drying state of the food waste can be grasped to detect when the drying is completed.

  When drying food waste, dry it directly from the drainage strainer to remove the broth from the drainage and dispose of it to the food waste processor, and dissolve it by passing hot air blown from the bottom of the drying net through the food waste. Even though it is drying, it is possible to dry it evenly with low power in a short time, and it is possible to automatically operate the processing equipment by detecting the drying state of food waste and detecting the time when drying is completed. Solving the wasting problem.

Until now, the hot air-type food waste processor has a problem that the hot air is blown and discharged from the top of the food waste, so that the food waste at the bottom is not dried.

However, in the present invention, all of the blowing air blown from the blower cartridge is supplied to the bottom of the drying net to pass through the food waste and discharged to the top of the drying net, so that even if the food waste is laminated to a thickness of more than 200mm The biggest feature is that it can be dried evenly without any distinction.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

It is supposed to. Therefore, when the food waste is dried, the valve is opened to supply external air to the inside, and when the valve is used as a drain or when the blower unit 31 is separated for cleaning, the valve is closed to block the inflow of sewage.

 The main body cover 11 covering the entire outer side of the main body 10 allows the wastewater introduced from the small drainage hole 15 and the exhaust hole 13 and the waste air generated after drying to the discharge hole 19. Since the high temperature and high humidity waste air discharged after drying is wrapped around the entire body 10, the internal heat of the body 10 is maintained even at a high temperature, thereby minimizing heat loss.

The blood on the bottom of the lower surface of the main body cover 11 is combined with the protruding portion of the drain hole 17 of the main body 10 to form a trap 18.

The buoyancy valve 33 prevents the high pressure air generated by the centrifugal force of the impeller at the time of blowing back to the inlet port of the impeller.

In addition, the blower unit 31 is unitized to separate the blower unit 31, as shown in FIG. 4, so that the blower unit 31 is easily installed and detached, thereby separating the blower unit 31 during cleaning. Therefore, the difficulty of cleaning due to the complicated structure is solved.

5 is a perspective view showing a drying net 20 according to the present invention, the cylindrical drying net 20 is seated on the blowing unit 31 as shown in the top (when used as a drain) sewage ( At the time of drying) is perforated to discharge the waste air, the bottom is bent inward, but the pedestal 22 is provided at the bent portion.

 The pedestal 22 of the drying net 20 is separated from the drying net 20 in order to facilitate the discharge of the dried food waste, and the bottom surface of the drying net discharges the wastewater and blows hot air blown from the blowing unit 31. Perforated in order to flow into the view 20, the drying rod 23 is formed with a blowing hole in the center is protruding.

The lid 61 at the top of the main body 10 has a function as a drainage lid 61 and a drainage drainage when drying food waste, and a small drainage drain is provided at one side of the lid 61 to cover the lid 61. When it is closed (when drying food waste), it is possible to drain the number of waters (sewage bypasses the drying net 20) without affecting the food waste being dried.

To this end, the small drain hole of the lid 61 includes a purging net 63 and a small lid 65 on the inside, and when the lid 61 is closed, the small drain and the drain hole 15 are connected. And, more detailed description by the drawings for the drainage of the sewage during drying will be described later.

8 is a state diagram showing that the waste water is drained without affecting the food waste that is being dried even when water is used in the sink while the food waste is being dried.

Where the food waste treatment apparatus is installed in accordance with the present invention can not know when and when to use the water in the number of sinks. Of course, the present invention is set to dry food waste at night after the end of the evening dishes, but even if it is not used only at night, and even if operated at night (during drying) there may be a case of using water for reasons such as a late night have.

 Even if wastewater is discharged during drying of food waste, it is assumed that the wastewater is discharged without affecting the food waste that has been dried.

Looking at the direction indicated by the arrow around the upper small lid 65 of Figure 1, even if the small lid 65 is completely closed, the edge portion of the small lid 65 does not contact the bottom surface can be seen that the void is formed have.

When the sewage flows into the sink, the sewage is also supplied to the air gap between the bottom surface and the small lid 65, so that buoyancy is generated in the small lid 65, and thus an arrow is indicated around the small lid 65 of FIG. As shown) the small lid 65 is lifted up and the small lid 65 is opened so that the sewage is drained to the small drain.

Sewage introduced into the small drain is discharged into the space between the main body 10 and the main body cover 11 as shown in FIG. 8 and again to the discharge hole 19 via the trap 18.

Figure 9 is a cross-sectional view of another embodiment of the food waste treatment apparatus according to the present invention, which shows the time when the food waste treatment apparatus according to the present invention is manufactured for the tabletop.

A tabletop body; A pedestal 76 equipped with a blower fan 73 and a heater at the bottom of the main body; It is seated on the top of the pedestal 76, the bottom is composed of a mesh net drying 77; An exhaust port 78 for exhausting the wet waste air generated after drying on the upper end of the main body; An intake port 79 for sucking fresh outside air; It is configured to include.

When food waste is put into the drying net 77 of the food waste processing apparatus configured as described above and the apparatus is operated, hot air generated from the lower blower fan 38 of the main body passes through the net perforated at the bottom of the drying net 77. And, the food waste is sent to the top of the drying net 77.

Part of the humid air passing through the food waste is discharged to the exhaust port 78, and the rest is introduced into the air outlet of the pedestal 76 through the space between the drying net 77 and the main body 70, and the blowing fan and the heating coil ( 37) is blown and heated to pass the food waste again. At this time, the fresh air is introduced from the outside by the suction fan 71 which is condensed on the same shaft as the blower fan 73.

Food waste processing apparatus operating as described above can be dried at the same time the top and bottom at the time of drying by passing all the hot air (inside of the drying net 77) food waste (operating inside the drying net 77) passing through the food fan from the bottom to the top. It is characterized in that, even if the blowing direction by changing the blowing direction from the top to the bottom of the drying net 77 can see the same effect.

In the control method for operating the food waste treatment apparatus, the amount and the physical properties of the food waste put into the apparatus are not constant every time it is input, and thus cannot be controlled only by the operation time. Therefore, in order to operate the device more efficiently, it is necessary to stop the operation of the processing device when it is completely dried by detecting the dry state of the food waste.

In order to solve the above-mentioned problems, the detection method at the time when the drying of food waste is completed may include a method of measuring exhaust temperature, measuring exhaust humidity, and measuring conductivity, but each of them has been put to practical use due to technical limitations. There is no technology.

However, the present invention is to calculate the size of the latent heat of evaporation when drying the food waste to detect the time when the drying is completed, a method for measuring the time that the power is applied to the heating coil being temperature controlled by the method and drying network There is a method of detecting when the drying is completed by comparing the temperature difference between the air entering and exiting.

First, in the method of calculating the latent heat of evaporation by detecting the time when the power is applied to the heating coil, a heating device is installed for one time when the heating coil is interrupted by installing a device for controlling temperature such as bimetal on one side of the drying network. The magnitude of the latent heat of evaporation can be measured by measuring the time applied to the coil to the electric machine.

In other words, if the sum of latent heat of evaporation and loss heat balances the amount of energy supplied to the drying network, the temperature inside the drying chamber is kept constant. However, if drying of food waste proceeds and the size of latent heat of evaporation decreases, the temperature inside the drying net increases inversely.

Therefore, if a device for temperature control is installed inside the drying net, when the inside of the drying net reaches a certain temperature, the temperature regulating device intercepts the heater, and the smaller the magnitude of the latent heat of evaporation, the more time is intermittent.

When applied, the temperature controller can calculate the amount of latent heat of evaporation when it detects the time that the heating coil is applied to the heating coil per unit time. It becomes possible.

The control method of the food waste processing apparatus using a method of detecting the time point at which the food waste is dried is described in a flow chart and described as follows.

Figure 10 is a flow chart illustrating a method for determining whether to continue the operation of the device by detecting the latent heat of evaporation in order to control the food waste treatment apparatus according to the present invention, the drying room is empty (the size of latent heat of evaporation 0) When the heating coil is heated only 10 seconds per 60 seconds is a flow chart prepared on the assumption that the food waste treatment apparatus that can maintain the internal temperature 70 °.

10 shows when the temperature control circuit, B using the bimetal, and is the same flow chart only slightly different depending on the parts used, (S150) to (S155); (S160) to (S165); (S170) to (S175); It has changed.

When power is applied to the food waste treatment apparatus (S110), the leachate generated from the food waste in the drying chamber 31 is naturally discharged for 30 minutes by the operation of the timer, and after 30 minutes (S120), the timer is turned off (S130). And blower is operated to generate hot air, hot air is to dry the food waste (S150). At this time, the internal temperature is increased according to the size of the latent heat of evaporation in the drying net. When the temperature of the drying chamber reaches 70 ° (S160), the heating coil is turned off and generates a clock pulse of 1 HZ (S170), and the timer and the clock pulse are countered (S180).

The clock pulse is counted only when the heating coil is powered off until the timer reaches 60 seconds (S190), and when the timer reaches 60 seconds but there are less than 50 clock pulses, the timer and clock pulse counter are reset and operation continues. (S200) When the clock pulse is 50 or more (S200), the operation of the blower is stopped (S210) and the operation of the food waste processing apparatus is terminated. (S220)

11 is a flowchart illustrating a control method when two heating coils are used to control the food waste treating apparatus according to the present invention.

When two heating coils are used, the internal coil temperature is supplied even if only 20W (threshold for maintaining 70 ℃) is supplied to the heating coil when the latent heat of evaporation of food waste inside the drying net is 0. Can maintain 70 ℃, heating coil 1 is supplied with 20W heating coil 2 with 80W of power.

If the heating coil has the same capacity as the above, and only the heating coil 2 is provided with a temperature control device such as bimetal, if the food waste is completely dried inside the processing device, no more power is applied to the heating coil 2. Therefore, if the heating coil 2 is not powered for a certain period of time, the size of the latent heat of evaporation can be considered to be close to zero, so the food waste treatment apparatus may be stopped.

Referring to the illustrated flow chart, when starting the operation of the food waste treatment apparatus, the heaters 1 and 2, power is supplied to the blower (S330), by detecting the temperature of the drying chamber (S350) when the exhaust temperature is 70 ℃ or more heaters If the power supply of 2 is cut off (S370) and maintained at 70 ° C. for 120 seconds (S380), the power of the heater and the blower is cut off (S390), and the operation of the food waste processing apparatus is terminated.

12 is a flow chart illustrating a method of determining whether to operate the device by comparing the difference between the temperature of the air intake and drying in the drying chamber in order to control the food waste treating apparatus according to the present invention. Is using a different principle.

Therefore, as shown in the embodiment of FIG. 11, when the power for maintaining the internal temperature of 70 ° C. is 20W, the heating coil 1 is supplied with 20W and the heating coil 2 is supplied with 80W.

In order to calculate the magnitude of latent heat of evaporation by using the temperature difference, the temperature of hot air flowing into the drying chamber from the air vent and the temperature of air discharged after drying are detected, and the magnitude of latent heat of evaporation can be calculated by comparing the difference between the two temperatures. According to the size of the latent heat it is possible to determine the operation and stop of the food waste treatment device.

This means that the hot air delivered to the inside of the drying room passes through the food waste, and when the food waste starts to dry, the moisture of the food waste vaporizes with water vapor, lowering the ambient air and temperature, and the lowered air is discharged. The difference is large. However, if the food waste is completely dried, even if the hot air passes through the food waste, the food waste is not dried anymore, so the temperature of the hot air is not lowered by the vaporization heat, so the temperature difference between the temperature of the hot air flowing into the drying chamber and the discharged hot air is small. .

Therefore, even if the hot air is measured and compared only the temperature entering the drying chamber and the discharge temperature can be seen not only the detection of the drying time of food waste but also the dry state of the food waste.

When the food waste treatment device is operated, power is supplied to the heating coils 1 and 2 and the blower to start the processing device (S530), and detects the temperature of the air sucked into and exhausted from the drying chamber (S550) and the exhaust hole (13). If the temperature of the group exceeds 70 ℃ (S560) the power of the heating coil 2 is cut off (S570). When the difference between the temperature supplied to the drying chamber and the discharged temperature during the operation of the food waste treatment apparatus does not reach 5 ° C. (S580), the operation is stopped by stopping the operation of all heaters and fans (S590).

The food waste treatment apparatus configured as described above improves the convenience of use by eliminating the process of transferring the food waste from the drain to the processing apparatus, and stacks the thick air by passing all the hot air generated in the blown cartridge through the food waste. The top and bottom of the food waste can be dried evenly, and when the drying of the food waste is completed, the processing device can be automatically operated. Solving the problem
