Food waste processor {FOOD WASTE DRYER}

The present invention relates to a food waste disposer, and more particularly to a household food waste disposer.

Generally, waste generated at home is separated into general waste, recyclable waste, food waste, etc. and then discharged. Among these, it is desirable to reduce the amount of food waste and discharge it with the moisture removed to prevent environmental pollution, facilitate collection and transportation, and resource recycling. Therefore, for this purpose, many household food waste disposers that can heat and dry food waste are being released. However, conventional food waste processors have limitations in efficiently drying food containing a large amount of moisture. This is especially true for, for example, fruits with a high sugar content, fiber, fish heads, etc.

The purpose of the present invention is to provide a food waste processor that can effectively dry food.

A food waste disposer according to the present invention has an internal space, a main body having an upper opening on an upper side of the internal space and a lower opening on a lower side of the internal space, a door for opening and closing the main body, and detachably coupled to the door.

It can be included.

Additionally, the opening of the basket may be arranged on the side at a point spaced apart from the floor.

Additionally, the strainer may be placed above the opening of the basket.

Additionally, the strainer may have a handle.

Additionally, the second heater may be a PTC heater.

In addition, it has an intake port connected to the second exhaust port of the duct and an outlet open to the outside, and may further include a filter having a demister filter and a deodorizing filter between the intake port and the outlet.

In addition, in order to initially quickly heat the inside of the basket, the first heater and the second heater are operated simultaneously for a predetermined time, and the first heater is operated for a predetermined time to primarily dry the food. The second heater may operate for a predetermined period of time to operate as a power saving effect step to completely dry the food.

Additionally, the strainer may be formed to slope downward from the center toward both ends.

In addition, the filter has a plurality of deodorizing filters, and the plurality of deodorizing filters are prepared by dividing each space using a perforated plate and filling the space with activated carbon. The upper part of the perforated plate may be closed without forming a hole.

In addition, the filter has a plurality of deodorizing filters, and the plurality of deodorizing filters are prepared by dividing each space using a perforated plate and filling the space with activated carbon. However, the lower part of the perforated plate may be blocked without forming a hole.

The food waste disposer according to the present invention heats and dries the food in the basket using a first heater (e.g., far-infrared ceramic heater), and draws air from the internal space of the main body, and some of it is used by the second heater (e.g., PTC). By heating it using a heater and then supplying it to the basket, food can be effectively dried using this hot air.

FIG. 1 shows the door 120 closed, and FIG. 2 shows the door 120 open and the strainer 140 This shows the appearance of separation. Additionally, FIGS. 3 and 4 are schematic side views of the food waste disposer 100 according to an embodiment of the present invention. FIG. 3 shows the door 120 closed, and FIG. 4 shows the door 120 open. will be. Additionally, Figure 5 is a cross-sectional view taken along line A-A in Figure 3.

1 to 5, the food waste disposer 100 includes a main body 110, a door 120, a basket 130, a strainer 140, a first heater 150, a duct 160, and a second heater ( 170) and a filter 180.

The main body 110 has an internal space (S), an upper opening 111 on the upper side of the internal space (S), and a lower opening 112 on the lower side of the internal space (S).

In addition, the main body 110 includes a fan (not shown) for causing air flow from the intake port 161 to the first exhaust port 162 and the second exhaust port 163 in the duct 160, which will be described later, and the temperature of the internal space (S). A temperature sensor (not shown) for measuring, a humidity sensor (not shown) for measuring the humidity of the internal space (S), a fan according to the temperature and humidity, a first heater (150) and a second heater (to be described later) 170) may further include a control unit (not shown) to control the device.

The door 120 is slidably coupled to the main body 110 through, for example, a rail (R), and serves to open and close the main body 110. However, since the structure itself is substantially the same as that known in the technical field or can be easily modified and derived by a person skilled in the art, detailed description thereof will be omitted.

Furthermore, in order to prevent the door 120 from being opened unintentionally in a closed state, magnets (not shown) may be attached to the main body 110 and the door 120, respectively, so that they are fixed to each other.

The basket 130 is detachably coupled to the door 120 and can move together with the door 120. Therefore, when the door 120 is closed, the basket 130 is located in the internal space S of the main body 110 (see FIGS. 1 and 3), and when the door 120 is opened, the basket 130 is exposed to the outside. (See Figures 2 and 4).

Additionally, the basket 130 has an opening 131 on its side at a point spaced apart from the bottom. This opening 131 is connected to the lower opening 112 of the main body 110 when the door 120 is closed and the basket 130 is located in the internal space S of the main body 110 (see FIG. 3).

The strainer 140 is formed in a plate shape and has a plurality of drain holes 141 over the entire area.

In addition, the strainer 140 is installed inside the basket 130, and in particular, it may be placed above the opening 131 of the basket 130. For this purpose, for example, the basket 130 may have a ledge 132 formed above the opening 131 on the side (see FIG. 2), and the strainer 140 may be supported on the ledge 132.

Additionally, the strainer 140 may have a handle 142 so that the user can easily remove and install the strainer 140.

This strainer 140 may be formed entirely flat as shown in FIG. 2 . Alternatively, the strainer 140 may be formed to slope downward from the center toward both ends, as shown in FIG. 6 . According to this, food can be spread evenly to both ends rather than concentrated in the center, while moisture can drip off more smoothly.

The first heater 150 is installed on the upper side of the internal space S of the main body 110 and serves to heat and dry the food in the basket 130. This first heater 150 may be, for example, a far-infrared ceramic heater.

Furthermore, a reflector (not shown) surrounding the first heater 150 so that the far-infrared rays can be concentrated toward the basket 130 rather than being dispersed to the surroundings, and a reflector (not shown) surrounding the first heater 150 to protect the first heater 150. A protective net (not shown) surrounding the surrounding area may also be installed.

The duct 160 includes an intake port 161 connected to the upper opening 111 of the main body 110, a first exhaust port 162 connected to the lower opening 112 of the main body 110, and a filter 180 to be described later. It has a second exhaust port 163 connected to the intake port 181. Accordingly, the duct 160 has a recirculation passage 164 that branches off from the intake port 161 to the first exhaust port 162 and a discharge passage 165 that branches off and continues to the second exhaust port 163 (see FIG. 3 ). ).

The second heater 170 is installed on the recirculation passage 164 of the duct 160 and serves to heat the air passing through it. This second heater 170 may be, for example, a PTC heater.

The filter 180 has an inlet 181 connected to the second exhaust port 163 of the duct 160 and an outlet 182 that opens to the outside.

This filter 180 is between the inlet 181 and the outlet 182, for example, a demister filter 183 for removing moisture in the air, a first deodorizing filter 184 for removing acidic odor components, and basic odor. It may sequentially have a second deodorizing filter 185 for removing components and a third deodorizing filter 186 for removing neutral odor components.

The demister filter 183 may be provided with a separate heater (not shown) inside it. According to this, moisture removal performance can be further improved by using the heater to heat moisture in the demister filter 183 and quickly dry it.

The first deodorizing filter 184, the second deodorizing filter 185, and the third deodorizing filter 186 can be prepared by dividing each space using a perforated plate (P) and filling the space with activated carbon. Therefore, as the air passes through the perforated plate P and passes through the first deodorizing filter 184, the second deodorizing filter 185, and the third deodorizing filter 186, odor components can be removed step by step.

However, the upper part of the perforated plate (P) may be blocked without forming a hole. Even if the space is fully filled with activated carbon, the activated carbon may be compressed and filled more densely due to impact or its own weight during storage, distribution, or use, creating an empty space at the top. In this case, there is a problem that odor components cannot be properly removed when air passes through the empty space. However, if the upper part of the perforated plate (P) is blocked, the above-mentioned problem can be prevented because air does not pass through the empty space even if an empty space is created in the upper part.

Additionally, the lower part of the perforated plate (P) may be blocked without forming a hole. When used for a long time, moisture may appear in the space over time. If the lower part of the perforated plate (P) is blocked, even if moisture accumulates in the lower part, it can be prevented from flowing to other spaces.

Based on the configuration described above, the operation method will be described below.

First, when the user puts food in the basket 130, more specifically on the strainer 140 and closes the door 120, the moisture from the food is primarily separated by the drain hole 141 of the strainer 140 and falls below it. do. However, as mentioned above, since the opening 131 is disposed on the side at a point spaced apart from the floor, it will be possible to prevent the moisture from flowing back into the duct 160 through the opening 131.

Next, the fan, first heater 150, and second heater 170 operate. First, when the first heater 150 operates, the food in the basket 130 can be heated and dried using far-infrared rays. Additionally, as the fan operates, air flows into the duct 160 from the internal space S of the main body 110 through the upper opening 111 and the intake port 161.

Some of this air flows along the recirculation flow path 164 and is further heated by the second heater 170 and then flows into the basket 130 through the first exhaust port 162, the lower opening 112, and the opening 131. supplied. Therefore, through this hot air, the food on the strainer 140 and the moisture under the strainer 140 can be reheated and dried more effectively.

Additionally, the remainder of the air flows along the discharge passage 165 and moves to the filter 180 through the second exhaust port 163 and the intake port 181. Accordingly, moisture is removed through the demister filter 183, various bad odors are removed while passing through the first deodorization filter 184, the second deodorization filter 185, and the third deodorization filter 186, and the discharge outlet 182 ) is discharged to the outside.

Meanwhile, in the entire cycle, the fan, first heater 150, and second heater 170 may all operate simultaneously and continuously.

Alternatively, the fan may operate continuously, but the first heater 150 and the second heater 170 may operate in a specific pattern. For example, the first heater 150 and the second heater 170 begin to operate simultaneously for an initially predetermined period of time (e.g., about 30 minutes) to quickly heat the inside of the basket 130 to the maximum. Thereafter, the first heater 150 operates for a predetermined period of time (e.g., about 5 hours when the food is relatively small, about 500-600 g; about 7 hours when the food is relatively large, about 500-1,000 g) to primarily heat the food. It is dried, and then the second heater 170 operates for a predetermined period of time (e.g., for about 3 hours when the food is relatively small, about 500-600 g; about 5 hours when the food is relatively large, about 500-1,000 g). You can even dry food.

The food waste disposer 100 described above is only one of the food waste disposers according to various embodiments of the present invention. The technical idea of the present invention is not limited to the above embodiments, and as described in the claims, includes all modifications that can be easily made by a person skilled in the art to which the present invention pertains.
