Referring to FIG. 1, the food waste treating apparatus 100 includes a main body 110, a machine room 111, a leg 113, a heat insulating material 115, a recessed portion 118, a door 120, and a release button 121. ), Container 130, cover 140, cooling device 150, cooling means (151, 152, 153), heating means 160, temperature sensor (163a, 163b, 163c, 163d), hinge 171 And an open / close detection sensor 173.

The container 130 in which food waste is accommodated may be manufactured in various shapes, such as a cylindrical shape, a rectangular parallelepiped shape, and the structure of the container 130 will be described later. However, when food waste (not shown) is directly stored in the food waste storage device 100, when the food waste (not shown) is discharged, the food waste storage device 100 is moved directly to a food waste collection place. Or a separate collection tool is required, and when the food waste processing apparatus 100 is washed after discharging the food waste (not shown), water penetrates into the machine room 111 and the machine room 111 as will be described later. ) May cause problems such as failure of various electric devices (not shown) such as the cooling device 150 installed therein. Therefore, it is good to make a separate container 130 for receiving food waste (not shown) and insert it into the food waste storage device 100 for use.

One side of the main body 110 is formed with a container receiving portion 117 is inserted into the container 130, the container receiving portion 117 has a shape corresponding to the shape of the container 130. That is, if the container 130 is cylindrical or rectangular parallelepiped, the container receiving portion 117 is also cylindrical or rectangular parallelepiped and is manufactured on a scale such that the outer surface of the container 130 can be in uniform contact with the surface of the container receiving portion 117. .

The container accommodating part 117 is provided with a cooling means 152 for cooling the container 130 and a heating means 160 for heating the container 130. The cooling means 152 and the heating means 160 are provided with a container ( It is installed adjacent to the container 130 to increase the efficiency of cooling or heating 130.

The cooling means 152 and the heating means 160 are installed to be evenly distributed over the entire outer surface of the container 130 so as to uniformly cool or heat the outer surface of the container 130 except for the open portion of the container 130. do. In the case where the cooling means 152 and the heating means 160 are linear, a zigzag shape or a coil (not shown) may be installed adjacent to the container 130 in a shape wound around the outer surface of the container 130 as shown. When the cooling means (not shown) and the heating means (not shown) are in the form of a plate or a plane, they are installed in a shape so as to surround the outer surface of the container 130. Install it.

Cooling means 152 and the heating means 160 may be wrapped with a heat insulating material 115, except for the container receiving portion 117 direction in order to increase the heat transfer efficiency with the container 130. The heat insulating material 115 should be made of a material having heat resistance and cold resistance, and may be interposed in a space between the main body 110 and the container accommodating part 117.

In the lower side of the main body 110, a machine room 111, which is a space in which a cooling device 150, a control device (not shown), a control panel (not shown), or the like is installed, is formed. Machine room 111 should be provided with a vent (not shown) so that the heat generated from the cooling device 150 and the control device (not shown), etc. to the outside of the main body 110, food waste storage device ( 100 is almost installed in the kitchen, so that a slit (not shown) or the like facing downward of the main body 110 may be installed in the ventilation hole (not shown) so that moisture or the like does not penetrate into the main body 110.

The briefly shown cooling device 150 represents a conventional cooling device used in a refrigerator, a cooling device, etc., and has undergone a compressor (not shown) and a compressor (not shown) in which the refrigerant is compressed to become a gas of high temperature and high pressure. Condenser (not shown), which emits heat of the refrigerant to the outside at low temperature and high pressure gas, capillary (not shown), and capillary tube in which the refrigerant passing through the condenser (not shown) expands and changes into a low temperature low pressure liquid. It is composed of an evaporator (not shown) that absorbs the heat of the object to be cooled as the refrigerant passing through the (not shown) phase changes to gas.

The illustrated cooling means 152 corresponds to the evaporator (not shown) described above to absorb heat from the vessel 130. Cooling means (151, 153) is a pipeline through which the refrigerant circulates to the cooling means 152 and the cooling device (150). Therefore, when the cooling device 150 is operated by receiving power from a control device (not shown), the refrigerant is circulated through the cooling means 151, 152, and 153 to cool the container 130, and thus the container 130 may be cooled. The temperature of the food waste (not shown) accommodated in the refrigerator is lowered and frozen.

The heating means 160 shown is a heating element using the heating phenomenon by the electrical resistance. Therefore, when the heating means 160 is operated by receiving power from a control device (not shown), heat is generated in the heating means 160, and the heat is transferred to the container 130 and received in the container 130. By thawing the surface of the food waste (not shown) frozen by the cooling means 152, the food waste (not shown) frozen on the inner surface of the container 130 is separated.

In this case, when the heating means 160 is operated for a long time, not only the surface of the food waste (not shown) but also other parts are thawed, and thus, a heating means 160 is added to a control device (not shown) by adding a timer (not shown). Limit the operating time or install temperature sensors 163a, 163b, 163c, and 163d adjacent to the outer surface of the container 130 to detect the temperature of the outer surface of the container 130. When a properly thawed temperature is sensed, the heating means 160 may be stopped.

Further, by using the temperature sensed by the temperature sensors 163a, 163b, 163c, and 163d, the cooling device 150 is operated and stopped by a control device (not shown), thereby preventing the food waste (not shown). By maintaining proper freezing and avoiding overcooling, energy can be used efficiently.

The door 120 is installed at one side of the main body 110, and is rotatably installed by the hinge 171 to open and close the opened portion of the container accommodation part 117. The door 120 may be filled with a heat insulator (125 of FIG. 2) to minimize the temperature change of the food waste (not shown) accommodated inside the container 130.

A portion of the main body 110 is provided with a lock detection sensor 173, the door 120 is closed to detect whether a part of the door 120 and a part of the main body 110 is in contact or close. The user removes the container 130 from the food waste storage device 100 to open the door 120 or discharge the food waste (not shown) to discharge the food waste (not shown) that was stored inside the container 130. When the door 120 is opened to be inserted into the container 130, the cooling device 150 may be stopped to conserve energy, and the food waste storage device may be left if the user leaves the door 120 open. Since the cooling performance of the 100 is reduced and energy is wasted, an acoustic device (not shown) or a light emitting device (not shown) installed in the control panel (not shown) is used when the door 120 is opened for a predetermined time. To alert the user.

As shown, the cover 140 may be detached from one surface of the door 120, that is, the lower part of the door 120. Cover 140 is manufactured in a shape that can cover the open portion of the container 130, used to store the food waste (not shown) by separating the container 130 from the food waste storage device 100 Or, in the process of using the food waste storage device 100 to prevent food waste (not shown) directly in contact with one surface of the door 120, or take out the container 130 from the food waste storage device 100 food In the process of discharging the garbage (not shown) has a function to prevent food waste (not shown) out of the container (130). The detachable structure of the door 120 and the cover 130 will be described later.

The food waste storage device 100 having the structure and function as described above is operated as follows.

The user accommodates food in the container 130 inserted into the container receiving unit 117 of the food waste storage device 100 and then uses a control panel (not shown) installed on one side of the food waste storage device 100. When the food waste storage device 100 is operated, the control device (not shown) is cooled until the temperature of the container 130 detected by the temperature sensors 163a, 163b, 163c, and 163d reaches a set temperature. The device 150 is operated to allow food waste (not shown) to be frozen.

Since food waste (not shown) can be accommodated as much as the contents of the container 130, when food waste (not shown) is generated, the food waste (not shown) may be further accommodated in the container 130 and stored in a frozen state. Can be. At this time, the food waste (not shown) is accommodated in the container 130 directly or contained in a waterproof bag or a pay-as-you-bag, so that the container 130, the inner surface of the container 130 and food waste (not shown), a waterproof bag and The surface of the payload envelope may freeze and become unable to separate. In particular, as described above, the food in our country is often caused by this characteristic of moisture.

Therefore, when taking out from the container 130 to discharge food waste (not shown), the user stops the operation of the cooling apparatus 150 by using a control panel (not shown) and operates the heating means 160. By heating the container 130, the surface of the frozen food waste (not shown) frozen on the inner surface of the container 130 is thawed by an appropriate amount so that it can be easily separated.

At this time, as described above, the container 130 is detected by the timer (not shown) or the temperature sensor (163a, 163b, 163c, 163d) installed in the control device (not shown) the operating time of the heating means 160 When the temperature of the container 130 reaches the set temperature, the control device (not shown) stops the operation of the heating means 160 and installs an acoustic device (not shown) in the control panel (not shown). (Not shown) or a light emitting device (not shown) to inform the user that food waste (not shown) has been separated from the container 130. The user sees the display of the control panel (not shown) and opens the door 120 to take the container 130 out of the container receiving part 117, and removes the cover 140 from the door 120 to remove the container 130. The food waste (not shown) is transported to the collection point with the open part of the cover.

Moisture content of food waste (not shown) may vary in part, but the higher the moisture content, the higher the specific heat, so that the container 130 is uniform throughout by the cooling means 152 and the heating water stage 160. Even if a heat exchange is performed, there may be a case in which the freezing or thawing is not partially performed. Therefore, the container 130 may be made of a material having excellent thermal conductivity, and the temperature sensors 163a, 163b, 163c, and 163d may be installed in plural so as to detect the temperature of various points of the container 130 as much as possible.

The container accommodating part 117 is provided with an insertion detecting sensor (not shown) for detecting whether the container 130 is inserted, and the cooling device 150 and the heating means when the container 130 is not accommodated. Energy can be saved by disabling 160. As the insertion detection sensor (not shown), a photo coupler, a contact sensor, a limit switch and a proximity sensor may be used.

On the other hand, in the state in which the cooling device 150 is stopped and the heating means 160 is operated to thaw a part of the food waste (not shown) for a long time without taking out the container 130 for another purpose. Since the frozen storage state of the food waste (not shown) may be degraded, it is preferable that the cooling device 150 is operated again after a predetermined time elapses.

When the user wants to put the food waste (not shown) in the container 130 inserted into the food waste storage device 100, the user's hand is usually holding food waste, food waste storage for the user's convenience A drive device for installing a proximity sensor (not shown), a voice recognition device (not shown), a switch that can be pressed by a user's hand or foot (not shown), and opening / closing the door to a part of the device 100. It is also possible to install (not shown), or to install the device that can open the door 120 by using the user's foot pressing force so that the user does not directly open and close the door 120 by hand. In addition, when the door 120 is opened and closed, a damper may be installed to prevent the door 120 and the main body 110 from colliding with each other and damage or noise may be adjusted to adjust the opening and closing speed of the door.

Since food waste such as fish and shellfish may be odor generated until it is received in the container 130 and frozen, the container 130 and the cover 140 are in contact with each other, and the main body 110 and the door 120 are in contact with each other. By installing a sealing means (not shown) such as a rubber magnet or a packing in the part to close the door 120, the container 130 and the cover 140 and the main body 110 and the door 120 are sealed, thereby causing odor. The food waste storage device 100 can be prevented from leaking to the outside, and the efficiency of the cooling device 150 can be improved.

In the case of using a compressor (not shown) using the above-described transmission apparatus as the refrigerating device 150, vibration may be generated by the operation of the compressor (not shown). It is good to install a plurality of legs 113 made of dustproof rubber so that vibration is not transmitted to the floor of a place where a food waste storage device (not shown) is installed. As described above, since the place where the food waste storage device 100 is installed is likely to be a kitchen, and thus the floor is inclined in many cases, the legs 113 may use a screw device (not shown). It is good to be able to adjust the food waste storage device 100 horizontally by adjusting the height.

Instead of the refrigerating device 150, the refrigerating means 151, 152, and 153 and the heating means 160, a thermoelectric element (not shown) using a thermoelectric phenomenon may be used. The thermoelectric element (not shown) is divided into a heat absorbing portion (not shown) and a heat dissipating portion (not shown), and a heat absorbing portion (not shown) of the thermoelectric element (not shown) is installed adjacent to the container 130. And the heat dissipation unit (not shown) is installed so as to be exposed to the outside of the main body 110 can release the heat of the container 130 to the outside of the main body 110, it is possible to replace the cooling means 152 can be used. . In addition, if the heat radiating portion (not shown) of the thermoelectric element (not shown) is installed adjacent to the container 130 and the heat absorbing portion (not shown) is installed to be exposed to the outside of the main body 110, the outside of the main body 110 It can be used to replace the heating means 160 because it can absorb the heat of the transfer to the container 130.

When using a thermoelectric element (not shown) as described above, when the food waste storage device 100 is operated, vibration and noise are not generated, so when the food waste storage device 100 is used in a place where quietness is required. Applicable
