Description

Technical Field

[0001] This invention relates to a kitchen appliance, and more particularly to a household oil extractor. Background Technology

[0002] A household oil extractor is a small kitchen appliance used in homes to extract edible oils from oilseed crops such as sesame, peanuts, and walnuts, meeting consumers' daily demand for fresh and healthy oils. With the increasing popularity of healthy eating concepts, homemade oil is gaining popularity, and the application of oil extractors, as a convenient kitchen appliance, is constantly expanding.

[0003] Currently, most household oil extractors on the market are single-function, lacking the ability to grind and pre-treat oilseeds, and are also unable to automatically add water to adapt to the processing techniques of different oilseed varieties. This forces users to rely on additional equipment for material processing, making operation cumbersome and inefficient. More importantly, existing oil extractors generally use contact heating plates as heating elements, which work by conducting heat through direct contact between the heating plate and the bottom of the pot. Because the arrangement path of the heating elements is fixed, heat often concentrates in the area directly above the heating elements, causing localized overheating of the bottom of the pot. This uneven heating method makes it easy for food to experience localized overheating during continuous heating, easily causing the raw materials to char and carbonize due to overheating. This not only destroys the original nutrients of the food but also produces harmful substances, posing a potential risk to food safety. Summary of the Invention

[0004] Therefore, it is necessary to provide a household oil extractor to address the shortcomings of existing technologies.

The sealing part 833 of the feeding seat 83 is inserted into the receiving groove 823 to seal the opening of the receiving groove 823 and protect the power transmission group 86. The guiding part 832 of the feeding seat 83 passes through the functional hole 8211 of the positioning seat 82 and extends into the feeding channel 8122. The worm 88 is set in the main channel 8121 and is installed in cooperation with the power output rod 87. The worm 88 and the power output rod 87 are coaxial. The blade 89 is installed at the bottom of the worm 88. The bottom of the worm 88 is locked in the vertical direction at the opening of the through hole 8011 of the cutter head 801. The retaining strip 8013 on the cutter head 801 is locked in the notch 8123. The internal thread of the positioning sleeve 802 is fitted with the external thread of the lower card seat 812 for installation, and the stepped hole 8021 of the positioning sleeve 802 presses the cutter disc 801 against the wall.

[0041] When the docking seat 84 of the crushing device 80 is installed on the main body seat 10, the bottom of the docking seat 84 is embedded into the docking groove 111 of the base 81, the mating joint 112 on the base 81 extends into the assembly groove 841 of the docking seat 84, the third locking block 842 on the docking seat 84 is locked into the third locking groove 113, and the power input rod 85 is installed in conjunction with the linkage main shaft 31.

[0042] During operation, the nuts are first crushed. The nut raw materials are placed in the feed trough 8311 of the feed seat 83. The control panel 100 starts the drive device 32. The nuts flow through the guide hole 8321 and the feed channel 8122 in sequence and enter the working area of ​​the worm gear 88. The drive device 32 drives the linkage spindle 31 to rotate. During the rotation of the linkage spindle 31, the linkage spindle 31 transmits power to the worm gear 88 through the power input rod 85, the power transmission group 86, and the power output rod 87. During the rotation of the worm gear 88, the worm gear 88 drives the blade 89 to rotate synchronously and squeeze the nuts to be transmitted to the blade 89. The rotating blade 89 crushes the nuts. The crushed nuts flow out from the sieve hole 8012 and fall into the dough pot 50 through the discharge cylinder 803.

[0043] After the nuts are crushed, the control panel 100 activates the heating element 42 and the fan 61. The fan 61 blows air through the guide channel 62 into the inner cavity of the cover body 411, and under the guidance of the flow obstruction part 432, it flows into the bottom of the air distribution plate 43. Then, it passes through the air distribution holes 431 on the air distribution plate 43, which disperse the flowing air upwards towards the heating element 42. The heat emitted by the heating element 42 is then blown into the heat conduction space 53 of the noodle pot 50 through the vent holes 416 of the heating cover 41 and flows out through the perforation 512. The hot air heats the inner pot 52 of the noodle pot 50, thereby heating the food inside the noodle pot 50. At the same time, the drive device 32 drives the stirring blade 70 to tumble and stir the nuts in the noodle pot 50. The temperature sensor 95 detects the temperature information inside the pot. When the temperature inside the pot and the duration of the sustained high temperature reach the set value, the control panel 100 activates the water pump 923 and the heating wire to inject hot water into the pot. During continuous steaming and cooking, oil is extracted from the crushed nuts.

[0044] In addition, such as Figure 2 and Figure 14As shown, to achieve better heat preservation and allow the nuts to be continuously steamed at high temperatures, the present invention also includes a pot lid 110. The pot lid 110 includes two plates 130 and several magnets 140 installed on the two plates 130. The plates 130 are C-shaped in shape on the horizontal plane. The magnets 140 are located at the end edge of the plates 130 in the arc direction. The bottom of the upper main body section 11 has a protruding seat 114. The upper end of the stirring blade 70 passes through the protruding seat 114. When the pot lid 110 is installed on the pan 50, the two plates 130 are spliced ​​on the horizontal plane. The inner sides of the two plates 130 surround the outer side of the protruding seat 114. The magnets 140 on the two plates 130 correspond one-to-one and attract each other. In addition, the plates 130 are also provided with avoidance holes to avoid the water inlet pipe 93, the temperature sensor 95 and the discharge cylinder 803.

[0045] In another embodiment, such as Figure 4 , Figure 5 As shown, it also includes a sealing cover 120. After the crushing device 80 is removed from the main body 10, the sealing cover 120 can be used to cover the docking groove 111 of the main body 10. On the one hand, it can prevent external dust or other debris from falling into the docking groove 111. On the other hand, it can effectively eliminate the safety hazards caused by the upper end of the linkage spindle 31 being exposed on the outside.

[0046] The beneficial effects of this household oil extractor are as follows: By setting up a heating component 40, a driving component 30, a stirring blade 70, a water adding device 90, a crushing device 80, and an air supply device 60, the driving component 30 drives the crushing device 80 to crush nuts, the heating component 40 heats the pan 50, the driving component 30 drives the stirring blade 70 to stir-fry the crushed nuts, and the water adding device 90 adds water to the pan 50 according to a set program. The entire oil extraction process has a high level of automation, requiring minimal manual intervention. In addition, the air supply device 60 sends air into the heating component 40, where it is heated and then flows into the pan 50, where the hot air further heats the pan 50, ensuring even heating and improving the heating effect of the food.

[0047] The technical features of the above embodiments can be combined in any way.
