With respect to other variants of bottom-mounted blow-by devices, those skilled in the art will be able to make corresponding modifications with reference to the present disclosure, which modifications are also within the scope of the present claims. The rotary filter-spray device for stopping leakage, filtering water and discharging slag/food has been described in various patents, and thus the description thereof will not be repeated.
For the convenience of understanding the present invention, the following embodiments of the present invention are specifically described:
fig. 1 to 6 show various improved bottom-side blow-by devices.
The schematic diagrams of FIGS. 1 to 6 are numbered as follows:
the pot body 1, the pot cover 2, the pot cover clapboard 202 and the bottom leakage spraying device 508;
a vertical leak pipe (device) 8, a rotary plug (device) 51; the device comprises a rotary spray head 51a, a rotary filter screen 51b, a rotary spray rod 51c, a transverse drain pipe 83, an electromagnetic valve 84, a protective sleeve 82 and a protective sleeve support rod 85; a showerhead top surface 51a1, a showerhead side surface 51a2, a rotary plug chamber 51 ac; the showerhead top opening 51a11/51a12, the showerhead side opening 51a 21;
a stirrer 531, a stirrer shaft 532; an elongated screw 433, an inner sleeve nut 534; a short and thick screw 5341, an outer sleeve screw 5342; motor 538, motor coupling 535, rotary plug rotation motor 541, and pulley assembly 536.
Fig. 1 is a schematic view of a cooking machine and a bottom leakage spraying device thereof. The cooking machine comprises a pot body 1, a pot cover 2 and a pot cover clapboard 202. The bottom of the pot body is provided with an opening, the bottom leakage spraying device 508 is arranged at the opening, the device comprises a hollow vertical leakage pipe device (vertical leakage pipe for short) 8, the vertical leakage pipe 8 is arranged at the opening 811 of the pot body, and obviously, the opening is superposed with the bottom opening of the pot body.
In the vertical leak conduit 8 there is a rotary plug device (simply referred to as rotary plug) 51, said rotary plug 51 being elongated and located in said vertical leak conduit 8, said vertical leak conduit either terminating at its lower end with an electromagnetic valve (see fig. 6) or being connected to a section of transverse leak conduit 83 (or a transverse leak conduit in a broad sense, see the description of the related patent already published), said transverse leak conduit 83 being connected perpendicularly to the bottom of the vertical leak conduit 8, as shown in fig. 2.
The upper part of the rotary spray plug is called as a rotary spray head 51a, the size of the wire diameter of the rotary spray plug is matched with the bottom opening of the pot body, so that the rotary spray head 51a is tightly matched with the bottom opening of the pot body, the bottom opening of the pot body can be closed, and the opening 811 of the vertical leakage pipe 8 in the pot body is also closed. The rotary spray plug can move up and down in the vertical leakage pipe, and can move upwards to enter the pot body from the vertical leakage pipe. The rotating plug 51 can also be moved downwards to cause the rotating nozzle to enter the bottom of the vertical leak pipe 8, as described in detail in the patent related to the invention. For the sake of brevity, the present invention only discusses moving up and back.
Rotatory nozzle 51a lower part is followed a disconnected annular rotary filter 51b, rotary filter 51 b's line footpath with pot body bottom opening 811 matches, works as rotatory nozzle 51a rises, drives rotary filter 51b can get into the pot body gradually, makes water in the pot body can get into through rotary filter 51b and arrange away in the vertical small opening 8, perhaps, arrange away through horizontal small opening 83.
The rotary plug 51 also includes a rotary spray bar 51c, and typically, the rotary spray bar 51c is set to be smaller than the line diameter of the rotary spray head 51a (see the related patent publication for a detailed discussion of the rotary spray bar), and the rotary spray head 51a can be moved up and down by the rotary spray bar. The most direct scheme for driving the rotary spray head 51a to move up and down by the rotary spray rod 51c is that the two are physically connected (for example, the two can be not physically connected, for example, a magnet is used for connecting the two, or a plugging mode is used, or a return spring is arranged on the vertical drain pipe 8 and acts on the rotary spray head 51a, the rotary spray rod 51c can push the rotary spray head 51a to move upwards into the pot body 1, but when the rotary spray rod 51c descends, the return spring pulls the rotary spray head 51a back into the vertical drain pipe 8.
The cross section of the rotary plug 51 may be a cylinder (for example, the cross section may be rectangular or in the shape of a staple when the bottom blow-by device is horizontally placed), and may be a cylinder without loss of generality, so that the rotary plug 51 can also rotate to obtain better stirring or cleaning effect, see the related patent.
Fig. 2-6 are schematic diagrams of a sleeve structure bottom leakage spray device, a pot body 1, a vertical leakage pipe 8 of the bottom leakage spray device, a transverse leakage pipe 83, and an electromagnetic valve 84 capable of opening or closing the transverse leakage pipe 83. The rotary plug 51 includes a rotary spray head 51a, a rotary screen 51b, and a rotary spray bar 51 c.
In fig. 2, the rotary spray rod 51c and the transverse drain pipe 83 are sealed through the protective sleeve 82, and the protective sleeve 82 and the rotary spray rod 51c form a sleeve structure, so that the rotary spray rod 51c can move up and down and rotate in the protective sleeve 82. The top of the rotary spray head 51a has an opening 51a12 connected to a conduit 51d in the rotary plug and can communicate with the outside of the rotary plug 51 through the conduit 51 d. The pipe 51d can be controlled to be opened or closed by a solenoid valve switch 51d1, or a check valve can be installed as required.
The top opening 51a11 of the rotary nozzle is communicated with the vertical drain pipe 8, and in order to prevent water from leaking into the vertical drain pipe 8 during cooking, the upper part of the protecting sleeve 82 can be made into a protecting sleeve isolating cap type 821 to block the opening 51a 11. Shield tube isolation cap 821 may be further extended and flexed (at which time shield tube isolation cap 821 has a series of openings therein for filtering debris, see opening 51c51 of fig. 3), to block side opening 51a21 of rotary spray head 51a, see the form of outer sleeve isolation cap 51c5 of fig. 3. The side opening 51a21 of the rotary nozzle is sealed by the vertical funnel 8 during cooking.
When the rotary spray rod 51c is lifted, the water in the pot body 1 can enter the vertical leak pipe 8 through the openings 51a11 and 51a21 and is discharged through the transverse leak pipe 83.
Fig. 3 shows a multi-sleeve rotary spray rod structure, taking a two-sleeve rotary spray rod as an example, the rotary spray rod 51c includes an outer sleeve 51ca and an inner sleeve 51cb, which form a sleeve pull rod structure, i.e. a sealing structure is between the two, and the inner sleeve 51cb can move up and down and rotate in the outer sleeve 51ca, thereby driving the rotary spray head 51a to move and rotate.
The outer sleeve 51ca may also form a sleeve structure with the sheathing tube 82, i.e., there is a sealing structure between the sheathing tube and the outer sleeve 51ca, and the outer sleeve 51ca can move up and down and/or rotate in the sheathing tube 82. The sealing structure means that the two are always in a sealing state in the relative movement process, and water vapor is prevented from leaking out from a gap between the two.
The upper portion of the outer sleeve 51ca may be in the form of an outer sleeve spacer cap 51c5 for shielding the top opening 51a11 and the side openings 51a21 of the spinner head 51 a. When the inner sleeve 51cb is raised, the above-mentioned opening 51a11/51a21 can be opened. To discharge food particles, an opening 51c51 may be formed in the top surface of the outer sleeve shielding cap 51c5, and when the rotary spray head 51a is raised, food particles may be discharged through the opening 51c 51. When the upper portion of the outer sleeve 51ca is formed as the outer sleeve isolation cap 51c5, the upper portion of the shield tube 82 may be provided with the shield tube isolation cap 821 or may be provided without the shield tube isolation cap 821.
The rotary spray bar 51c is rotated by a rotary spray bar rotating motor 541 via a pulley unit 536.
In fig. 4A, the elongated screw 533 is matched with the nut 534, the nut 534 is connected to the rotary spray bar 51c, and the motor 538 drives the elongated screw 533 to rotate through the coupling 535, so as to push the rotary spray bar 51c to move up and down (i.e., drive the rotary spray plug to move up and down). Practitioners in the art will appreciate that when the elongated screw 533 is rotated, if the rotating spray bar 51c is simply moved up and down, then some forcing means is required to prevent the rotating spray bar 51c from rotating, such as a male and female detent. It is common knowledge based on these knowledge, and the worm linear motion device is described in the related patent already disclosed in the present invention, and will not be further described for the sake of brevity.
In fig. 4B, the elongated screw 533 is matched with the nut 534, the nut 534 is connected with the inner sleeve 51cb, and the motor 538 drives the elongated screw 533 to rotate through the coupling 535, so as to push the inner sleeve 51cb to move up and down. It is known to practitioners in the art that when the screw 533 is rotated, some forcing means, such as a male and female detent, is required to prevent the inner sleeve 51cb from rotating in order to move the inner sleeve 51cb up and down. It is common knowledge based on these knowledge and is described in the related patents disclosed in this invention, and further description is not made for the sake of brevity.
One advantage of fig. 4B over fig. 4A is that a combination of options is possible, for example, the outer sleeve 51ca is responsible for only rotation (and thus rotation of the inner sleeve 51 cb) and not up and down movement, while the inner sleeve 51cb is responsible for only up and down movement and not rotation; also for example, the outer sleeve 51ca is only responsible for the up-and-down movement (and the inner sleeve 51cb is carried up-and-down movement) without rotation, while the inner sleeve 51cb is only responsible for the rotation without the up-and-down movement, so that the sealing design is relatively easy. In fact, the sealing design is important for bottom-mounted blow-by devices, including the openings 51a11/51a21 on the rotating spray head, etc., and sealing considerations, such as sealing with a rubber material, are taken into account.
It will be appreciated that when the outer sleeve 51ca is required to rotate within the sheath 82 (and to rotate the inner sleeve 51 cb), with full reference to and analogy with the configuration of fig. 3, the rotary-piston rotary motor 541 rotates the outer sleeve 51ca via the pulley arrangement 536; when the outer sleeve 51ca is required to move up and down in the sheath tube 82 (and to drive the inner sleeve 51cb up and down), referring to and analogous to the form shown in fig. 4A, there is an elongated screw in the outer sleeve 51ca, which screw is engaged with a nut fixed in the outer sleeve 51ca, and when the screw is rotated, the outer sleeve 51ca is pushed up and down in the sheath tube 82.
Fig. 4C differs from fig. 4B in that in the schematic of fig. 4C, the motor 538 in the outer sleeve drives a short, thick screw 5341 via a coupling 535, which engages with a helical tooth 5342 on the inner wall of the outer sleeve 51ca, causing the motor 538 and the slidable inner sleeve 51cb to move up and down. Compared with fig. 4A and 4B, the structure of fig. 4C has the advantage that the cavity 51ac of the rotary plug can be emptied, and other components such as a temperature sensor, a one-way valve, etc. can be placed.
Obviously, for the telescopic sleeve rod structure composed of the protecting sleeve and the rotary spray plug, the structure of fig. 4C can be completely referred to and analogized, that is, the rotary spray plug can slide in the protecting sleeve, the motor in the protecting sleeve drives a section of short and thick screw rod to rotate through a coupler, the screw rod is matched with the screw teeth on the protecting sleeve, so that the motor and the slidable rotary spray plug move up and down.
It should be noted that, when the telescopic sleeve rod structure formed by the sheathing tube and the rotary plug is a multi-sleeve rod structure, that is, when the rotary spray rod 51c of the rotary plug includes the outer sleeve 51ca and the inner sleeve 51cb, the manner in which the inner sleeve 51cb moves up and down/rotates in the outer sleeve 51ca may be the same as or different from the manner in which the outer sleeve 51ca moves up and down/rotates in the sheathing tube 82.
For example, a slender screw rod is arranged in the inner sleeve, the screw rod is matched with a nut fixed in the inner sleeve, when the screw rod rotates, the inner sleeve is pushed to move up and down in the outer sleeve, a motor in the protective sleeve drives a short and thick screw rod to rotate through a coupler, and the screw rod is matched with screw teeth on the protective sleeve, so that the motor and the slidable outer sleeve move up and down.
Fig. 5A is a schematic view of the installation of the stirrer or blade of the first type 1, in which the outer sleeve 51ca and the inner sleeve 51cb form a sleeve structure, and the sheath 82 and the outer sleeve 51ca also form a sleeve structure. The motor 538 rotates in the inner sleeve 51cb, the shaft 532 is driven to rotate through the coupling 535, the shaft 532 penetrates through the rotary nozzle 51a, and finally the stirrer or the blade 531 is driven to rotate (the stirrer 531 can be replaced by a grinder for a soymilk maker).
Fig. 5B is a schematic view of the 2 nd stirrer or blade installation, in which the outer sleeve 51ca and the inner sleeve 51cb form a sleeve structure, and the sheath 82 and the outer sleeve 51ca also form a sleeve structure. The agitator or blade 531 is attached to the top surface of the inner sleeve 51cb (or the top surface of the rotary plug 51), is in contact with the rotary nozzle 51a, and rotates with the rotation of the inner sleeve 51 cb. The inner sleeve 51cb may be rotated by the motor 538, or alternatively, the inner sleeve may be rotated by the outer sleeve 51 ca.
Fig. 5C is a schematic view of the installation of the stirrer or blade of type 3, the protective sleeve 82 and the rotary spray rod 51C form a sleeve structure, and the stirrer or blade 531 is installed on the top surface of the rotary spray head 51a (or the top surface of the rotary spray plug 51), is connected with the rotary spray head 51a, and rotates along with the rotation of the rotary spray rod 51C. Alternatively, rotary spray bar 51c may be rotated by motor 538.
Fig. 5D is a schematic diagram illustrating the installation of the 4 th stirrer or blade, the protective sleeve 82 and the rotary spray rod 51c form a sleeve structure, the stirrer or blade 531 is on the top surface of the rotary spray head 51a (or the top surface of the rotary spray plug 51), the motor 538 is in the rotary spray plug 51, the driving coupling 535 rotates to drive the rotating shaft 532 to rotate, and the rotating shaft 532 penetrates through the rotary spray plug 51 to drive the stirrer or blade or the knife 531 to rotate.
FIGS. 5A, 5B, 5C and 5D are referred to as external blades or agitators.
As can be seen from fig. 4A, 4B, 4C to 6, since the sleeve rod structure is adopted, a closed space is provided for the driving motor 538 to be installed in the rotary spray plug, and as a result, the bottom blow-by device is more compact in structure.
The present invention is illustrated by the embodiment that the bottom leaking jet device comprises the horizontal leaking pipe 83, and the technical essence of the present invention is general, for example, in fig. 6, the horizontal leaking pipe is not provided, and the sheath pipe 82 is fixed in the vertical leaking pipe 8 by the support rods 85 (usually 2-4 support rods). The sheath tube 82 and the rotary spray bar 51c constitute a telescopic pull bar structure. The drive power and signals required by the motor 538 may be directed through the hollow support rod into the rotating spray bar 51 c. Obviously, rotary spray bar 51c may further employ a telescopic pull rod configuration.
