Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a cooking device. Background Art

[0002] Currently, household appliances such as rice cookers usually have other cooking functions besides cooking rice, such as making soup.

[0003] However, when meat and other ingredients are needed in the cooking process of soup, the user needs to boil the meat several times before using the rice cooker to make the soup, manually skim off the grease and scum floating on the water surface, and then add the meat and other ingredients into the rice cooker, so as to make a broth without scum and with a better taste.

[0004] However, this operation process is relatively complicated, especially the initial step of blanching the meat, which requires multiple manual removal of grease and scum, increasing the burden on users and reducing their enthusiasm for cooking. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art that the process of making soup in an electric rice cooker is complicated and increases the burden on users, thereby providing a cooking device.

[0006] The present invention provides a cooking device, comprising: an outer shell, comprising a storage groove with an opening arranged toward the bottom side;

[0007] The adsorption device has a retracted state in which it is retracted into the receiving groove and an extended state in which it is extended out of the receiving groove away from the opening, and is suitable for adsorbing minced meat, scum and grease;

[0008] The lifting device is connected to the storage groove and the adsorption device, and is suitable for driving the adsorption device to switch between the contracted state and the extended state.

[0009] An adsorption cavity is arranged in the adsorption device, and a plurality of adsorption holes communicating with the adsorption cavity are arranged at least on the peripheral side surface of the adsorption device.

[0010] The cover body also includes a cleaning device, which includes:

[0011] A clean water tank, arranged inside the outer shell;

[0012] A water inlet pipe, connecting the clean water tank and the receiving tank, on which a pump body is arranged, suitable for extracting clean water from the clean water tank to flush the adsorption device in a contracted state;

[0013] The water outlet pipe is connected to the receiving tank and the turbid water tank, and the turbid water tank is suitable for recovering the turbid water mixed with minced meat, scum and grease after the adsorption device is cleaned.

[0014] The clean water tank and the dirty water tank are arranged inside the outer shell and are adjacent to each other.

[0015] The two connection surfaces of the water inlet pipe and the water outlet pipe connected to the receiving groove are arranged opposite to each other.

[0016] A pressure boosting chamber is arranged on the water inlet pipe at a position adjacent to the receiving groove, and a water pressure booster is built in the chamber.

[0017] The lifting device comprises: a connecting bracket, which is arranged on the top surface of the adsorption device, and a plurality of radially arranged support arms are evenly arranged along the central axis of the top surface of the adsorption device, and a first ball joint structure is arranged at the end of each support arm;

[0018] A plurality of second ball joint structures are respectively arranged in the receiving grooves corresponding to the first ball joint structures;

[0019] A plurality of connecting rod structures, correspondingly connecting the first ball joint structure and the second ball joint structure;

[0020] The power member is connected to the second ball joint structure and is suitable for controlling the synchronous movement of the second ball joint structure.

[0021] The adsorption device is adapted to the shape of the storage groove and is arranged in a square shape. A fixed shaft is arranged along the central axis of the top surface of the adsorption device. The connecting bracket is engaged with the fixed shaft and movably connected to be suitable for rotating along the fixed shaft.

[0022] The adsorption device is adapted to the shape of the storage groove and is cylindrically arranged, and the adsorption device is fixedly connected to the connecting bracket.

[0023] The technical solution of the present invention has the following advantages:

[0024] 1. The present invention provides a cooking device, comprising: an outer shell, comprising a storage groove with an opening arranged toward the bottom side; an adsorption device, having a contracted state contracted into the storage groove and an extended state extending out of the storage groove away from the opening, suitable for adsorbing minced meat, scum and grease; a lifting device, connecting the storage groove and the adsorption device, suitable for driving the adsorption device to switch between the contracted state and the extended state.

[0025] By arranging a retractable adsorption device on the outer shell, the user can control the lifting device during the blanching stage before the cooking process to drive the adsorption device to extend out of the storage groove to absorb the minced meat, scum and grease in the soup in the pot. After the absorption is completed, the adsorption device is driven back to the retraction groove to start the cooking process. In this way, the adsorption device is set to automatically remove impurities in the soup, which reduces the burden on users and improves their enthusiasm for cooking.

[0026] 2. A cooking device provided by the present invention also includes a cleaning device, including: a clean water tank, arranged inside the outer shell; a water inlet pipe, connecting the clean water tank and the receiving tank, on which a pump body is arranged, suitable for extracting clean water in the clean water tank to flush the adsorption device in a contracted state; a water outlet pipe, connecting the receiving tank and a turbid water tank, and the turbid water tank is suitable for recovering turbid water mixed with minced meat, scum and grease after the adsorption device is cleaned.

[0027] By setting up a cleaning device, when the adsorption device takes the impurities in the soup into the adsorption cavity from the adsorption hole and changes from an extended state to a contracted state, the water pump is started to draw water from the clean water tank to the receiving tank, and then the adsorption device is cleaned, and the impurities in the adsorption cavity are flushed by the water flow and flow out from the water outlet pipe to the turbid water tank for easy collection. On the one hand, such a setting can realize the effective cleaning of the adsorption device and enable the adsorption device to be repeatedly used for many times, which is convenient for effectively treating the impurities in the soup. On the other hand, such a setting can prevent the impurities in the adsorption cavity from being quickly treated and prevent them from falling into the soup again.

[0028] 3. In a cooking device provided by the present invention, the water inlet pipe and the water outlet pipe are respectively arranged opposite to two connecting surfaces connected to the storage groove.

[0029] This arrangement can ensure smooth water flow, increase the water flow rate, reduce flow resistance, and allow the water impact force from the water inlet pipe to effectively act on the adsorption chamber, avoiding the inner wall of the storage tank from absorbing and dispersing the water impact, thereby improving the cleaning efficiency of the adsorption chamber.

[0030] 4. In a cooking device provided by the present invention, a pressure boosting chamber is provided on the water inlet pipe adjacent to the storage groove, and a water pressure booster is built in.

[0031] Such arrangement, on the one hand, can increase the water pressure of the water flow in the cleaning device, increase the water flow velocity, and improve the cleaning effect of impurities in the adsorption device in the storage tank by providing a boosting chamber with a built-in water pressure booster. On the other hand, the boosting chamber is arranged in the water inlet pipe and is arranged adjacent to the storage tank position, so that the storage tank position is the position with the maximum water flow velocity, further increasing the water flow impact force on the adsorption device, thereby ensuring the complete removal of impurities in the adsorption device.

[0032] 5. The present invention provides a cooking device, in which the lifting device includes: a connecting bracket, which is arranged on the top surface of the adsorption device, and a plurality of radially arranged support arms are evenly arranged along the central axis of the top surface of the adsorption device, and a first ball joint structure is arranged at the end of each support arm; a plurality of second ball joint structures are arranged in the storage groove corresponding to the first ball joint structure; a plurality of connecting rod structures are correspondingly connected to the first ball joint structure and the second ball joint structure; a power piece is connected to the second ball joint structure and is suitable for controlling the synchronous movement of the second ball joint structure.

[0033] The adsorption device is connected through a connecting bracket, the storage groove is connected through a second ball joint structure, and the second ball joint and the first ball joint structure arranged on the peripheral support arm of the connecting bracket are connected through a connecting rod structure. In this way, the lifting device can be arranged as a spatial connecting rod structure, and the conversion of the adsorption device between the contracted state and the extended state is realized by controlling the degree of freedom of the device in the space and the synchronous driving action of the power part on the second ball joint structure. The spatial connecting rod mechanism includes multiple connecting rods, which can realize the stable movement of the adsorption device in the vertical direction to avoid the phenomenon of skewing and being unable to reset. In addition, in this way, during the movement of the adsorption device, the connecting bracket can realize the synchronous rotation movement of the connecting bracket along the central axis of the top surface of the adsorption device, and the rotation control of the adsorption device can be realized by controlling whether the connecting bracket is fixedly connected to the adsorption device.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Embodiment 1:

[0052] like Figure 1 - Figure 7 As shown, this embodiment provides a cooking device, which may be an electric rice cooker or a soup burger, etc., comprising: an outer shell 1, an adsorption device 2 and a lifting device 3.

[0053] The outer shell 1 includes a cover body and a pot body. The cover body includes a surface cover and an inner cover that are detachably fixedly connected. The surface cover is arranged above the inner cover. A heat preservation cover plate is embedded in the inner cover on the side facing away from the surface cover. A storage groove 11 with an opening is arranged in the middle of the heat preservation cover plate. When the cover body and the pot body are matched, the heat preservation cover plate is usually arranged on the bottom side of the cover body, so the storage groove 11 is opened toward the pot body below.

[0054] The adsorption device 2 has a retracted state in which it is retracted into the receiving groove 11 and an extended state in which it extends out of the receiving groove 11 toward the back opening, and can adsorb minced meat, scum and grease in the soup of the pot.

[0055] The lifting device 3 connects the storage tank 11 and the adsorption device 2. In the present embodiment, the lifting device 3 is arranged inside the storage tank 11, and can drive the adsorption device 2 to switch between a contracted state and an extended state.

[0056] By arranging a retractable adsorption device 2 on the cover body, the user can control the lifting device 3 during the blanching stage before the cooking process to drive the adsorption device 2 to extend out of the storage groove 11, so as to absorb the minced meat, scum and grease in the soup in the pot body matched with the cover body. After the absorption is completed, the adsorption device 2 is driven to retract into the retractable groove and the cooking process is started. In this way, the adsorption device 2 is arranged to realize the automatic removal of impurities in the soup, reduce the burden on the user, and improve the user's enthusiasm for cooking.

[0057] The adsorption device 2 is provided with an adsorption chamber 21, and at least a plurality of adsorption holes 22 communicating with the adsorption chamber 21 are provided on the peripheral side of the adsorption device 2. The adsorption holes 22 are evenly distributed on each peripheral side, and the hole diameter and distribution density can be adaptively selected according to the impurities in the soup.

[0058] In this embodiment, the adsorption device 2 also includes a negative pressure generating device, so that an adjustable negative pressure is set inside the adsorption chamber 21, and the minced meat, scum and grease in the pot soup are sucked into the adsorption chamber 21. After the impurities are collected, the volume increases and cannot flow out of the adsorption chamber 21, thereby completing the adsorption and removal of impurities. In this embodiment, in addition to the peripheral side surface of the adsorption device 2, the bottom surface of the adsorption device 2 is also provided with adsorption holes 22. As a convertible embodiment, the top surface of the adsorption device 2 can also be provided with adsorption holes 22.

[0059] As another convertible embodiment, the size of the adsorption holes 22 can be variably set. Adsorption holes 22 with large pore sizes are set on the top surface of the adsorption device 2 to facilitate the entry of impurities into the adsorption chamber 21, while adsorption holes 22 with small pore sizes are set on the surrounding side and bottom surfaces of the adsorption device 2 to facilitate the discharge of soup and leave impurities.

[0060] The specific form and setting position of the negative pressure generating device are not limited. In the present embodiment, the negative pressure generating device is a suction device, which is arranged in the adsorption chamber 21 and can control the negative pressure in the adsorption chamber 21 by starting and stopping the operation.

[0061] In the present embodiment, the aperture of each adsorption hole 22 gradually decreases in the direction toward the adsorption chamber 21. In this way, the aperture of the adsorption hole 22 is gradually reduced in the direction of entering the adsorption chamber 21. While ensuring that the adsorption range of the adsorption hole 22 remains unchanged, the effect of the negative pressure in the adsorption chamber 21 to absorb minced meat, scum and grease is effectively improved. In addition, the aperture of the direction in which minced meat scum and grease flow out of the adsorption chamber 21 is also reduced, thereby efficiently achieving the adsorption of minced meat scum and grease.

[0062] As a convertible implementation, a one-way device such as a one-way valve may be provided on each adsorption hole 22. As another convertible implementation, the aperture of a single adsorption hole 22 may remain unchanged.

[0063] In this embodiment, a cleaning device is also provided on the cover body, including: a clean water tank 41 , a water inlet pipe 42 , a pump body 43 , a water outlet pipe 44 and a dirty water tank 45 .

[0064] A clean water source for washing is arranged inside the clean water tank 41. The location of the clean water tank 41 is not limited. As a preferred embodiment, it is arranged inside the outer shell 1. As a convertible embodiment, it can also be arranged outside the outer shell 1. The water inlet pipe 42 connects the clean water tank 41 and the storage tank 11. The end of the water inlet pipe 42 extending into the clean water tank 41 is provided with a pump body 43, which can extract clean water in the clean water tank 41 to wash the adsorption device 2 in the contracted state; the water outlet pipe 44 connects the storage tank 11 and the turbid water tank 45. The turbid water tank 45 can recover the turbid water mixed with minced meat, scum and grease after the adsorption device 2 is washed.

[0065] By setting up a cleaning device, when the adsorption device 2 takes the impurities in the soup into the adsorption chamber 21 from the adsorption hole 22 and changes from the extended state to the contracted state, the water pump is started to draw the water source in the clean water tank 41 to the storage tank 11, and then the adsorption device 2 is cleaned, and the impurities in the adsorption chamber 21 are flushed by the water flow and flow out from the outlet pipe 44 to the turbid water tank 45 for easy collection. On the one hand, such a setting can realize the effective cleaning of the adsorption device 2 and enable the adsorption device 2 to be repeatedly used for many times, which is convenient for effectively treating the impurities in the soup. On the other hand, such a setting prevents the impurities in the adsorption chamber 21 from being quickly treated and falling into the soup again.

[0066] In this embodiment, the clean water tank 41 and the dirty water tank 45 are both arranged inside the interlayer of the pot wall on the outer shell 1 and are arranged adjacent to each other, and a partition is arranged in the middle, so that the steps of replenishing the clean water tank 41 and cleaning the dirty water tank 45 can be carried out simultaneously, reminding each other, and avoiding the lack of water in the clean water tank 41 or the overflow of the dirty water tank 45. In addition, as a preferred embodiment, a one-way valve is arranged on at least the water outlet pipe 44 to avoid the backflow of impurities in the dirty water tank 45, and as a convertible embodiment, a filter screen or a one-way membrane is arranged on the partition.

[0067] In addition, the connection surface between the water inlet pipe 42 and the receiving tank 11 is arranged opposite to the connection surface between the water outlet pipe 44 and the receiving tank 11. This arrangement can ensure smooth water flow, increase the flow rate of water flow, reduce flow resistance, so that the impact force of water flow from the water inlet pipe 42 can effectively act on the adsorption chamber 21, avoid the inner wall of the receiving tank 11 to absorb and disperse the impact of water flow, and improve the cleaning efficiency of the adsorption chamber 21.

[0068] As a preferred embodiment, a boosting chamber 46 is further provided on the water inlet pipe 42 adjacent to the receiving tank 11, and a water pressure booster is built in. In this arrangement, on the one hand, by providing the boosting chamber 46 with a built-in water pressure booster, the water pressure of the water flow in the cleaning device can be increased, the water flow rate can be increased, and the cleaning effect of the impurities in the adsorption device 2 in the receiving tank 11 can be improved. On the other hand, the boosting chamber 46 is provided on the water inlet pipe 42 and adjacent to the receiving tank 11, so that the receiving tank 11 is at the position of the maximum water flow rate, further increasing the water flow impact force on the adsorption device 2, and ensuring that the impurities in the adsorption device 2 are completely removed. As a convertible embodiment, the boosting chamber 46 and the booster may also not be provided.

[0069] The lifting device 3 comprises: a connecting bracket 31, a connecting rod structure 33, a second ball joint structure 32 and a power part.

[0070] The connecting bracket 31 is arranged on the top surface of the adsorption device 2. Three radially arranged arms 311 are evenly arranged along the central axis of the top surface of the adsorption device 2. The end of each arm 311 is provided with a first ball joint structure 312; three second ball joint structures 32 are arranged in the storage groove 11 corresponding to the first ball joint structure 312; three connecting rod structures 33 are correspondingly hinged to the first ball joint structure 312 and the second ball joint structure 32; the power member is connected to the second ball joint structure 32, and can control the synchronous movement of the second ball joint structure 32. In this embodiment, the power member is a motor, and the movement of multiple second ball joint structures 32 is synchronously controlled by multiple motors through a single-chip microcomputer or serial-parallel connection.

[0071] The adsorption device 2 is connected through a connecting bracket 31, the storage groove 11 is connected through a second ball joint structure 32, and the second ball joint and the first ball joint structure 312 arranged on the peripheral support arm 311 of the connecting bracket 31 are connected through a connecting rod structure 33. In this way, the lifting device 3 can be set as a spatial connecting rod structure 33, and the conversion of the adsorption device 2 between the contracted state and the extended state is realized by controlling the degree of freedom of the device in the space and the synchronous driving action of the power part on the second ball joint structure 32. In addition, the spatial connecting rod mechanism includes three identical connecting rods, which can make the adsorption device 2 evenly stressed in three directions, thereby realizing the stable movement of the adsorption device 2 in the vertical direction, avoiding the phenomenon of skewing and being unable to reset. On the other hand, in the process of the movement of the adsorption device 2, the connecting bracket 31 can realize the synchronous rotation movement of the center axis of the top surface of the adsorption device 2, and realize the rotation control of the adsorption device 2 by controlling whether the connecting bracket 31 is fixedly connected to the adsorption device 2.

[0072] In this embodiment, the adsorption device 2 is adapted to the shape of the storage tank 11 and is arranged in a square shape. A fixed shaft 23 is arranged along the central axis of the top surface of the adsorption device 2. The fixed shaft 23 penetrates into the adsorption chamber 21 in the vertical direction and is fixed to the bottom of the adsorption chamber 21. The connecting bracket 31 is engaged with the inner groove of the fixed shaft 23 arranged outside the adsorption chamber, and can rotate along the fixed shaft 23. This arrangement can prevent the rotation of the adsorption device 2 while realizing the control of the movement process of the adsorption device 2 in the vertical direction by the lifting device 3, thereby preventing the adsorption device 2 from being misaligned with the storage tank 11.

[0073] Example 2

[0074] In this embodiment, based on the embodiment 1, the adsorption device 2 is adjusted to be cylindrical, and the adsorption device 2 is fixedly connected to the connecting bracket 31 .

[0075] Due to the cylindrical configuration, the rotation of the adsorption device 2 during the movement will not affect the matching relationship with the storage tank 11. In addition, the rotational movement can also reduce the amount of soup in the soup material retained in the storage cavity, avoiding the waste of soup. As a convertible embodiment, the adsorption device can also be other rotationally symmetrical three-dimensional structures. As another convertible embodiment, the fixed shaft 23 can be omitted. As another convertible embodiment, the connecting bracket 31 can also be omitted. Each ball joint structure is set at the top of the adsorption cavity 21, which can save materials.

[0076] Example 3

[0077] like Figure 8 - Fig.10 In this embodiment, based on the first and second embodiments, the negative pressure generating device is adjusted to a sealed telescopic barrel, which is respectively connected to the storage tank and the lifting device 3. The sealed telescopic barrel is sealed and fixed to the adsorption device 2 through an annular pressure plate, and a middle hole is provided in the middle of the top of the adsorption device 2, and a connecting bracket is provided inside the middle hole. A fixed shaft 23 is provided in the middle of the connecting bracket 31, and a plurality of pressure plate connecting holes are evenly provided around the middle hole, which can be fixedly connected to the annular pressure plate.

[0078] Such an arrangement can control the pressure in the adsorption chamber 21 of the adsorption device by the expansion and contraction of the sealed telescopic barrel, thereby achieving the adsorption effect of the adsorption chamber 21 on minced meat, scum and grease.

[0079] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
