DETAILED DESCRIPTION

[0048] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0049] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the term "connected" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0050] The terms "top," "bottom," "above," "below," and "on" used throughout the description refer to relative positions of components of a device, such as the relative positions of top and bottom substrates within a device. It will be understood that devices are multifunctional regardless of their orientation in space.

[0051] The working surface of the present invention can be a plane or a curved surface, can be inclined, or can be horizontal. For the convenience of description, the present invention is placed on a horizontal surface and used on a horizontal surface, and "high and low" and "up and down" are defined in this way.

[0052] A specific embodiment of the present invention is as follows Figures 1 to 3 As shown, a cooking device with a sterilization function is disclosed, comprising:

[0053] The cooking drum 3 includes a cooking chamber 301, in which materials (such as ice cubes and lemon slices) are processed. The materials refer to fruits, vegetables, ice cubes and other substances that can be placed in the cooking device for processing;

[0054] The self-cleaning component includes a steam generator 8 and a water pump 7. The steam generator 8 is configured to at least heat the liquid into steam; the steam generator 8 includes an inlet and an outlet. The inlet is connected to the external water source or / and the water supply system 6 through the water pump 7, and the outlet is connected to the cooking chamber 301 to prepare for introducing steam into the cooking chamber for sterilization.

[0055] The cooking device with a sterilization function of the present invention (hereinafter referred to as the cooking device) is equipped with a self-cleaning component and uses high-temperature (about 100°C, the boiling point of liquid) steam to sterilize the part that comes into contact with food (i.e., the cooking chamber), thereby improving food safety and hygiene.

[0056] The inlet is connected to the water supply system 6 and / or the external water source through the water pump 7 and the first pipe; the outlet is connected to the cooking chamber 301 through the second pipe 81.

[0057] The liquid required by the self-cleaning component can be provided by an external water source or stored in a water supply system. In this embodiment, the self-cleaning component includes a water supply system 6, a water pump 7, and a steam generator 8, which are connected in sequence. The inlet is connected to the water supply system 6 via the water pump 7 and a first pipe, so that the liquid in the water supply system 6 can be pumped into the steam generator.

[0058] The cooking device includes a steam sterilization mode and a liquid flushing mode. In the liquid flushing mode, the steam generator is inoperative, forming a channel connecting the water pump and the second pipe. The water pump directly pumps liquid into the cooking chamber for flushing. In the steam sterilization mode, the steam generator is inoperative, and the water pump pumps liquid into the steam generator, converting it into steam. The steam is then introduced into the cooking chamber for high-temperature sterilization. In other words, even when the steam generator 8 is inoperative, it still forms a channel connecting the water pump and the second pipe 81. Thus, the cooking device's self-cleaning modes include at least two modes: steam sterilization and liquid flushing. In the liquid flushing mode, the steam generator is inoperative, and the water pump directly pumps liquid from the water supply system into the cooking chamber 301 for flushing. In the steam sterilization mode, the steam generator is inoperative, and the water pump pumps liquid from the water supply system into the steam generator, converting it into high-temperature steam. The high-temperature steam is then introduced into the cooking chamber 301 for high-temperature sterilization. Preferably, the cooking device can select the liquid flushing mode before the high-temperature sterilization mode during self-cleaning to achieve a better self-cleaning effect.

[0059] According to one embodiment of the present invention, the cooking device further includes:

[0060] The main unit 2 includes a drive motor 21;

[0061] The extrusion element 1 is detachably assembled in the cooking chamber 301;

[0062] One end of the cooking chamber 301 is provided with an output port for the output shaft of the driving motor 21 to pass through, so that the driving motor 21 is connected to the extrusion element 1 for driving the extrusion element 1 to rotate synchronously.

[0063] The self-cleaning component can be integrated into the main unit 1, or can be set as a whole and separately on the main unit 1, or can be partially integrated into the main unit 1 and partially set as a separate part on the main unit 1. That is, the water supply system can be set as a fixed water tank or a detachable water tank or directly connected to a water pipe for water supply.

[0064] In this embodiment, the steam generator 8 and the water pump 7 are located in the housing of the main unit, and the water supply system 6 is configured as a detachable water tank, which is separately provided on the housing of the main unit.

[0065] Preferably, the extrusion element 1 comprises:

[0066] The rotating shaft 11 has one end configured to be drivingly connected to the output shaft of the driving motor 21 and the other end rotatably connected to the cooking chamber 301;

[0067] A spiral wall 12 is provided on a side wall of the rotating shaft 11 to define a spiral channel 101 together with the rotating shaft 11. The spiral channel 101 extends from one end of the rotating shaft 11 to the other end.

[0068] The spiral channel 101 includes an inlet end and an outlet end, and the width of the spiral channel 101 gradually decreases from the inlet end to the outlet end.

[0069] Preferably, the spiral channel 101 is opened toward the outside of the side wall of the rotating shaft. The width of the spiral channel 101 refers to the width of the opening of the spiral channel 101. For example, the width of the inlet end is P1, and the width of the outlet end is P2.

[0070] The utility model uses an extrusion element provided with a spiral channel with a gradually varying width to squeeze materials (such as ice cubes and lemon slices) to extract juice. On the one hand, it can be used to extract lemon juice and stimulate the aroma of lemon, and at the same time, it can crush ice cubes of larger volume. On the other hand, the extrusion element is installed in the cooking device and is driven by a drive motor to extrude the material, which is not only safe and hygienic but also highly efficient.

[0071] Preferably, the ratio of the width of the inlet end to the width of the outlet end is 1.08 to 3.8, that is, P1 / P2=1.08 to 3.8, so as to ensure that the material is not blocked in the spiral channel while improving the pressurization effect of the material in the spiral channel.

[0072] To improve the compactness of the cooking device, the inlet and outlet are located at opposite ends of the shaft, and are relatively far apart from each other. That is, the inlet and outlet are located on opposite sides of the shaft, and are far apart from each other. That is, the inlet is located at one end of the shaft, and the outlet is located at the other end of the shaft, and the opening directions of the inlet and outlet are opposite to each other (for example, the inlet is facing upward and the outlet is facing downward). That is, the rotation angle α of the spiral channel 101 extending from the inlet and outlet to the outlet is N*360°+180°, where N≥0 and is an integer. In this embodiment, α=180°.

[0073] Preferably, the extrusion element 1 is horizontally positioned within the cooking chamber 301, with the inlet located at the right end of the rotating shaft's sidewall and the outlet located at the left end. Initially, the inlet faces upward, while the outlet faces downward. This arrangement not only facilitates the flow of materials into and out of the spiral channel, but also makes the cooking device more compact.

[0074] Specifically, the rotating shaft 11 includes a transmission end 111 and an assembly end 112. The transmission end is provided with a concave or convex structure on the outside for transmission connection, and the concave or convex structure for transmission connection mates with the output shaft of the drive motor. For example, a transmission groove 102 is provided on the outside of the transmission end 111 (the side away from the assembly end 112). The transmission groove 102 mates with the output shaft of the drive motor 21, that is, the output shaft inserted into the transmission groove 102 can drive the extrusion element to rotate synchronously with it. The assembly end 112 is rotatably connected to the cavity wall of the cooking chamber 301 (which is located opposite the cavity wall with the output port). Preferably, the inlet end of the spiral channel 101 is close to the transmission end 111, and the outlet end of the spiral channel 101 is close to the assembly end 112 to achieve a better extrusion effect.

[0075] In order to further improve the extrusion effect of the extrusion element on the material, the depth of the spiral channel 101 gradually decreases from the inlet end to the outlet end.

[0076] Preferably, the rotating shaft and the spiral wall are made by integral molding, for example, they can be integrally cast. Further preferably, the material of the extrusion element 1 is food-grade stainless steel.

[0077] It should be noted that the gap between the spiral wall of the extrusion element 1 and the side wall of the cooking chamber 301 is small. Preferably, the gap between the two is not greater than 3 mm. Such a setting ensures that the extrusion element rotates smoothly. On the one hand, it is not easy to be stuck by large particles of pulp, so that the material is always located in the spiral channel as much as possible to ensure the cooking effect of the material; on the other hand, it does not hinder the circulation of liquid in the cooking chamber, and facilitates the self-cleaning operation of the cooking barrel.

[0078] The cooking device also includes a feed drum 4 and a discharge drum 5 connected to the cooking drum 3. The cooking drum 4 is provided with a feed channel 401, which communicates with the cooking chamber 301 and faces the inlet end of the extrusion element 1, allowing material to pass through the feed channel 401 and enter the spiral channel 101. The discharge drum 5 is provided with a discharge channel 501, which communicates with the cooking chamber 301 and faces the outlet end of the extrusion element 1, allowing material processed by the extrusion element to be discharged from the discharge channel 501 out of the cooking chamber 301.

[0079] In this embodiment, the cooking cylinder 3 is arranged horizontally, and the feed cylinder 4 and the discharge cylinder 5 are both arranged vertically. The center lines of the feed cylinder 4 and the discharge cylinder 5 are parallel, and the center lines of the two are respectively perpendicular to the center line of the cooking cylinder 3. The feed cylinder 4 is located on the right part of the upper side wall of the cooking cylinder 3, and the discharge cylinder 5 is located on the left part of the lower side wall of the cooking cylinder 3.

[0080] The inner sidewalls of the cooking drum 3 (i.e., the sidewalls of the cooking chamber) are smooth to facilitate cleaning of the tea processing device. Alternatively, the inner sidewalls of the cooking drum 3 are provided with spiral protrusions that mate with the spiral channel 101, sealing the spiral channel except for the inlet and outlet ends. This prevents fruits and vegetables from escaping into the spiral channel, improves the squeezing effect of the squeezing element, and enhances the cooking efficiency of the tea processing device. To facilitate the entry of materials into the spiral channel from the inlet, the feed drum 4 is provided with a pusher plug 41 that is detachably mounted at the inlet of the feed drum 4 and mates with the feed drum 4. Specifically, the pusher plug 41 comprises a connected handle and a pusher portion. The pusher portion mates with the feed drum 4 to be inserted into the feed channel 401. Preferably, the pusher portion is no less than the length of the feed channel 401. The handle portion is always located outside the feed drum 4, and its width is no less than the outer diameter of the feed drum 4, so that the pusher plug 41 can be operated by the handle. Specifically, the handle portion projects downward to completely cover the feed drum 4. That is, the shape of the pusher plug 41 is similar to a "T" shape, the pushing portion constitutes the lower vertical portion of the "T", and the handle portion constitutes the upper horizontal portion of the "T".

[0081] To facilitate the discharge of processed materials from the cooking chamber, the cooking device also includes a discharge baffle 31 located within the cooking chamber 301. The discharge baffle 31 is rotatably connected to the assembly end 112 of the rotating shaft 11. Specifically, the discharge baffle 31 is provided with a rotating hole that cooperates with the assembly end 112 of the rotating shaft 11. That is, the assembly end 112 of the rotating shaft 11 can rotate within the rotating hole, thereby improving the rotational stability of the rotating shaft. The position of the discharge baffle 31 cooperates with the discharge barrel 5 to allow the materials processed by the extrusion element to be discharged from the cooking chamber 301 by the discharge barrel 5. The discharge baffle is set at the left end of the rotating shaft and is used to push the extruded and crushed food out of the discharge channel. Preferably, a bearing that cooperates with the assembly end is provided in the rotating hole to enable smoother rotation of the extrusion element 1.

[0082] In order to facilitate the removal of the extrusion element 1 from the cooking barrel 3, the outer side of the cooking barrel 3 (the side away from the output port) is provided with an end cover 32 that can open or close the cooking chamber, that is, the end cover 32 can open or close the cooking chamber 301. After the end cover 32 is opened, the discharge baffle 31 and the extrusion element 1 can be taken out of the cooking chamber 301 in sequence for maintenance, replacement, and cleaning. When the end cover 32 is closed, its inner side wall constitutes the cavity wall of the cooking chamber 301 opposite to the output port. Exemplarily, the end cover 32 can be installed on the outer side of the cooking barrel 3 in a detachable manner such as threaded connection, clamping, snap connection, magnetic connection, etc. The end cover 32 can also be hinged to the side wall of the cooking barrel 3 at one end and clamped to the side wall of the cooking barrel 3 at the other end to achieve opening or closing of the cooking chamber.

[0083] Preferably, the end cap 32 is integrally formed with the discharge baffle 31 to facilitate removal of the extrusion element 1. Exemplarily, the cooking barrel 3 (excluding the end cap), the feed barrel 4, and the discharge barrel 5 are integrally formed and then detachably connected to the main unit 2 for maintenance, replacement, cleaning, transportation, etc. Alternatively, the cooking barrel 3, the feed barrel 4, the discharge barrel 5, and the outer shell of the main unit 2 are integrally formed to improve the structural stability and connection strength of the cooking device. Alternatively, the cooking barrel 3 (excluding the end cap), the feed barrel 4, and the discharge barrel 5 can also be detachably connected, and the cooking barrel 3 and the main unit 2 are further detachably connected for transportation, maintenance, etc. In actual application, the selection can be made according to the specific situation.

[0084] The outlet is connected to the feed channel 401 through the second pipe 81, so as to introduce the high-temperature steam generated by the steam generator into the feed channel 401, the cooking chamber 301, and the discharge channel 501, and perform high-temperature treatment on the parts in direct contact with the material to improve food safety and hygiene.

[0085] In liquid flushing mode, the steam generator does not work, and the water pump pumps the liquid in the water supply system directly into the feed channel 401, the cooking chamber 301, and the discharge channel 501 for flushing; in steam sterilization mode, the steam generator works, and the water pump pumps the liquid in the water supply system into the steam generator to convert it into high-temperature water vapor, which is then introduced into the feed channel 401, the cooking chamber 301, and the discharge channel 501 for high-temperature sterilization.

[0086] The water pump 7 is connected to the water supply system 6 via a first pipe, and the water pump 7 is connected to the steam generator via a first pipe; the steam generator is connected to the side wall of the feed barrel 4 via a second pipe.

[0087] Preferably, the second pipe 81 is a hard pipe, and the second pipe 81 extends from the outlet of the steam generator 8 to the outside of the shell of the main machine and is connected to the side wall of the feed barrel 4.

[0088] The first pipeline can be a soft pipe or a hard pipe.

[0089] The cooking device also includes a control panel 22, which is disposed in the housing of the main unit. The control panel 22 is configured to be electrically connected to at least the drive motor 21, the water pump 7, and the steam generator 8 to control the working progress of the drive motor 21, the water pump 7, and the steam generator 8.

[0090] To achieve a more compact structure and a more rational and stable layout for the cooking device, an assembly chamber is located near the center of the main unit. The drive motor 21, control panel 22, water pump 7, and steam generator 8 are located within this chamber, with the drive motor positioned above these panels, and the water pump below them. The main unit's housing defines a first area at the front for holding a cup 9. This area is located directly below the cooking drum, allowing the cup 9 to be placed directly below the discharge drum to receive the processed material. A second area is defined at the rear for assembling the water supply system. The first and second areas are located on the front and rear sides of the assembly chamber, respectively.

[0091] This cooking device uses a squeezing element with a gradually varying spiral channel to quickly crush ice and extract lemon juice, stimulating the lemon aroma while also breaking up large ice cubes. The squeezing element is installed within the cooking drum, providing high safety and effectively preventing safety malfunctions caused by accidental operation. The feed drum is positioned above the squeezing element, while the discharge drum is located below it, enabling automatic discharge. Furthermore, a self-cleaning component facilitates regular cleaning and disinfection of the device, ensuring safety, efficiency, reliability, and sanitation. This ensures safer and more hygienic food preparation and enhances the device's automation level.

[0092] This cooking device features a self-cleaning component. The steam generator automatically heats water into high-temperature steam as needed, performing high-temperature cleaning and sterilization of food-contact components. This device is safe, efficient, reliable, and hygienic, boasting a high degree of automation. Furthermore, the feed drum is positioned above the cooking drum, while the discharge drum is located below, enabling automatic discharge. The extrusion element is built into the drum, effectively preventing safety issues caused by accidental operation.

[0093] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
