Description

Cooking utensil

Technical Field

The invention relates to the technical field of cookers, in particular to a cooking appliance.

Background

The existing cooking appliances such as electric cookers, electric pressure cookers and the like gradually increase the composite functions of automatic rice adding, water adding, stirring and the like while finishing the functions of steaming and boiling, so that the products develop towards automation and intellectualization. Products with stirring functions in the market at present have functions of only using in one stirring scene, such as beating and sending out with a quick stirring function and an egg beater, or have functions of covering the use of multiple stirring scenes, such as slowly kneading dough and quickly beating and sending out. In a variety of different mixing scenarios, the mixing function is usually switched between the usage scenarios by the user himself adjusting the mixing speed (e.g. inputting a specified rotation speed). However, the user's misoperation (the mixing speed is not matched in a specific mixing scene) is unavoidable, which may cause the bad phenomena such as damage of the mixing arm or splashing of the food material, and also may reduce the service life of the appliance.

The present application therefore proposes an improved cooking appliance to at least partially solve the above technical problem.

In this summary, concepts in a simplified form are introduced that are further described in the detailed description section. This summary of the invention is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

In order to at least partially solve the above problems, the present invention discloses a cooking appliance, comprising: the cooker body assembly comprises a cooker body seat, an inner pot arranged on the cooker body seat and a cooker body cover arranged on the cooker body seat, and a cooking space is formed between the cooker body cover and the inner pot;

the cooker body assembly is detachably connected with the machine body assembly;

the cooker body assembly comprises a cooker body assembly, a cantilever assembly and a handle, wherein one end of the cantilever assembly is arranged in the cooker body assembly, the other end of the cantilever assembly is positioned above the cooker body assembly, and the cantilever assembly can be switched between an upper side working position and a lower side working position;

the stirring assembly is arranged on the pot body cover and is driven by a first driving mechanism in the cantilever assembly to rotate, the stirring assembly comprises at least a first stirring arm or a second stirring arm, and the first driving mechanism drives the first stirring arm to rotate at a first speed, or the first driving mechanism drives the second stirring arm to rotate at a second speed different from the first speed;

an assembly position detection assembly; and

the assembly position detection assembly is in signal connection with the control device so as to feed back a target position signal of the cantilever assembly at the upper side working position or the lower side working position to the control device; the cantilever assembly located at the upper side working position supplies the first stirring arm to be correspondingly connected, and the cantilever assembly located at the lower side working position supplies the second stirring arm to be correspondingly connected.

According to the cooking utensil, the first stirring arm and the second stirring arm have different rotating speeds and are driven to rotate by the same driving mechanism, so that the different rotating speeds of the stirring arms can be met by one driving mechanism, the rotating speed coverage of the stirring arms from low speed to high speed can be met, and the multi-scene application of the stirring function is realized; and the cantilever assembly can be switched between the upper side working position and the lower side working position, the assembly position detection assembly can feed back in-place signals to the control device, the stirring arms with different rotating speeds are matched with the cantilever assemblies with different working positions, and the situation that the corresponding stirring arms can only be assembled correctly under the specific position (corresponding to a specific stirring scene) of the cantilever assembly can be realized, so that the adverse phenomena that the stirring arms are damaged, food splashes and the like due to misoperation of a user and assembly errors can be avoided.

Preferably, when the working position of the cantilever assembly is matched with the stirring assembly in error, the first driving mechanism feeds back an idle-running signal to the control device.

From this, controlling means can in time learn cantilever subassembly and stirring subassembly matching mistake, and then indicate to the user.

Preferably, the cooking utensil further comprises a prompting device, the prompting device is in signal connection with the control device, and when the working position where the cantilever assembly is located is wrong with the matching of the stirring assembly, the control device controls the prompting device to send out an assembly error prompting message.

Therefore, under the condition that the cantilever assembly is in the upper side working position and the second stirring arm is connected with the pot body cover, the installation height of the second stirring arm is not enough, at the moment, the first driving mechanism idles without load, and therefore the prompt device sends out prompt information of assembly errors; when the first stirring arm is connected to the cooker body cover and the user selects to move the cantilever assembly to the second position, the first driving mechanism can be jacked by the first stirring arm and cannot reach the lower working position in the process that the cantilever assembly moves downwards to the lower working position, so that the assembly error prompt information can be sent out through the prompt device.

Preferably, the first stirring arm has a first mounting height and the second stirring arm has a second mounting height, the second mounting height being smaller than the first mounting height.

Preferably, the first agitating arm has a first mounting shoulder, and a vertical distance from a top surface of the first mounting shoulder to the top surface of the first agitating arm in a state where the first agitating arm is attached to the pot body cover is defined as the first mounting height.

It will be appreciated that the pot body lid typically has a mounting aperture, the first stirring arm typically exposed through the mounting aperture upon attachment to the pot body lid, and the first stirring arm typically being restrained to the pot body lid by a first mounting shoulder, such that the first mounting height is defined by the vertical distance from the top surface of the first mounting shoulder to the top surface of the first stirring arm.

Preferably, the vertical distance between the upper working position and the lower working position defines a third height, the first mounting height is greater than the sum of the second mounting height and the third height.

Thus, since the first mounting height is greater than the sum of the second mounting height and the third mounting height, the first stirring arm can be equipped with the first drive mechanism in the case where the boom assembly is located in the upper working position (corresponding to a rapid stirring scenario); when the suspension arm assembly is about to be located at the lower working position (corresponding to the slow stirring scene), the first stirring arm will be pressed against the first driving mechanism and cannot reach the lower working position.

Preferably, the machine body assembly comprises a second driving mechanism, the second driving mechanism comprises a second motor and a lead screw assembly, the lead screw assembly is connected with the cantilever assembly, and an output shaft of the second motor drives the lead screw assembly to vertically drive so as to drive the cantilever assembly to move along the direction of the rotation axis of the inner pot.

Thereby, the cantilever assembly can be driven to be movable by the second driving mechanism.

Preferably, the assembly position detecting assembly includes a photo coupler disposed on the cantilever assembly, and a light blocking detection plate disposed on a body bracket of the body assembly, the light blocking detection plate cooperating with the photo coupler to detect whether the cantilever assembly is located at the upper side working position and the lower side working position.

Therefore, whether the cantilever assembly is located at the upper side working position and the lower side working position can be accurately known through the matching of the photoelectric coupler and the light blocking detection plate.

Preferably, the first drive mechanism has at least first and second different outputs, the first output being for mounting the first stirring arm and the second output being for mounting the second stirring arm.

Preferably, the first driving mechanism includes a first motor, at least one set of planetary assemblies connected to the first motor, an output end of the first motor forms the first output end, an output end of the planetary assembly at the final stage forms the second output end, and an end surface of the second output end surrounds an end surface of the first output end.

Thus, the first mixing arm is connected to the output shaft of the first motor, and the second mixing arm is connected to the output of the planetary assembly.

Preferably, the end surface of the first output end is flush with the end surface of the second output end, or the end surface of the first output end protrudes from the end surface of the second output end.

Thereby, the assembly of the first stirring arm with the second stirring arm is facilitated.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

The present invention provides a cooking appliance 100. The cooking appliance 100 according to the present invention may be an electric cooker, an electric pressure cooker, or other cooking appliances 100, and the cooking appliance 100 may have various functions such as cooking porridge, cooking soup, etc. in addition to the function of cooking rice.

A cooking appliance 100 according to a preferred embodiment of the present invention will be described in detail with reference to fig. 1 to 8.

As shown in fig. 1, the cooking appliance 100 of the present embodiment is a split cooking appliance. Specifically, the cooking appliance 100 includes a body assembly 120 and a pot body assembly 110, the pot body assembly 110 being detachably connected to the body assembly 120.

The pot body assembly 110 may specifically include a pot body seat 111 and a pot body cover 112. The pot body seat 111 may be provided therein with a cylindrical inner pot accommodating portion, and the inner pot 113 may be freely placed in or taken out of the inner pot accommodating portion to facilitate cleaning of the inner pot 113. The upper surface of the inner pot 113 has a circular opening for containing a material to be heated, such as rice, soup, etc., into the inner pot 113. The pot body cover 112 is openably and closably provided on the pot body base 111, and when the pot body cover 112 is closed on the pot body base 111, a cooking space can be formed between the pot body cover 112 and the inner pot 113.

As shown in fig. 1, the body assembly 120 is substantially L-shaped, and a heating device may be disposed at a horizontal section of the L-shaped body assembly 120. The heating means may be a heat generating coil disc. The pot body seat 111 and the heating means may be electrically connected in a state where the pot body assembly 110 is rested to the machine body assembly 120, and the heating means may heat the inner pot 113 in a state where the cooking appliance 100 is powered on.

A control panel of the cooking appliance 100 may be integrated in the body assembly 120, and the control panel (one of the control means) is a control center of the entire cooking appliance 100, and controls all electrical components, such as a heating means, a first driving mechanism 131 and a second driving mechanism 121 described later, an assembly position detecting assembly, and the like.

With continued reference to fig. 1, a cantilever assembly 130 is disposed above the pot body assembly 110. The boom assembly 130 is horizontally connected to a vertical section of the body assembly 120 as shown in fig. 1, and the boom assembly 130 is configured to be switchable between an initial position from top to bottom, an upper working position, and a lower working position in a direction along the axis of rotation of the inner pot 113.

Specifically, the movement of the boom assembly 130 in the direction along the axis of rotation of the inner pot 113 may be driven by the second drive mechanism 121. As shown in fig. 1, the second driving mechanism 121 may include a second motor 122 and a lead screw assembly 123, the lead screw assembly 123 is connected to the suspension arm assembly 130, and an output shaft of the second motor 122 drives the lead screw assembly 123 to move up and down, so as to drive the suspension arm assembly 130 to move along the rotation axis of the inner pot 113.

The initial position of the boom assembly 130 is understood to mean the position of the boom assembly 130 when the second drive mechanism 121 of the body assembly 120 is not operating after the machine is powered on. The boom assembly 130 may be moved vertically downward from the initial position to the upper operating position as described above, or may continue to move vertically downward from the upper operating position to the lower operating position as described above. Of course, the boom assembly 130 may also be moved vertically upward from the lower operating position to the upper operating position and the initial position in sequence.

More specifically, the cantilever assembly 130 may be provided with a photo coupler 132, and a light blocking plate (not shown) engaged with the photo coupler 132 is provided on the body bracket of the body assembly 120. The photo-coupler 132 and the light blocking detection plate together constitute an assembly position detection assembly, and the assembly position detection assembly can feed back an in-place signal to the control panel when the cantilever assembly is at the corresponding working position. Specifically, the light blocking plate in cooperation with the photo-coupler 132 can detect whether the cantilever assembly 130 is in the initial position, the upper working position, and the lower working position. In general, the light-blocking detection plate is vertically arranged on the machine body bracket, and the light-blocking detection plate is provided with a detection point 0, a detection point 1 and a detection point 2 from top to bottom in advance, wherein the detection points can be gaps formed on the light-blocking detection plate. When the cantilever assembly 130 is at the initial position, the photoelectric coupler 132 is just aligned to the detection point 0, so that the photoelectric coupler 132 is in a conducting state, and the main control chip on the control panel in communication connection with the photoelectric coupler 132 can receive an in-place signal sent by the photoelectric coupler, thereby being capable of judging that the cantilever assembly 130 is at the initial position. Similarly, when the cantilever assembly 130 is in the upper working position, the photo coupler 132 is aligned with the detection point 1, and when the cantilever assembly 130 is in the lower working position, the photo coupler 132 is aligned with the detection point 2.

It can be understood that the vertical distance between the detection point 0 and the detection point 1 is the vertical distance that the cantilever assembly 130 moves vertically downward from the initial position to the upper working position, and the vertical distance between the detection point 1 and the detection point 2 is the vertical distance that the cantilever assembly 130 moves vertically downward from the upper working position to the lower working position. In other embodiments, the cantilever assembly 130 may further have third, fourth, etc. predetermined positions, and the predetermined position that the cantilever assembly 130 needs to reach may correspond to the position of the detection point on the light blocking plate according to actual requirements, that is, whether the cantilever assembly 130 reaches the predetermined position may be detected by the photocoupler 132.

Next, referring to fig. 1, 6 and 8, the cooking appliance 100 further includes a stirring assembly 140. The stirring assembly 140 is provided to the pot body cover 112 and is driven to rotate by the first driving mechanism 131 in the cantilever assembly 130. The stirring assembly 140 includes at least a first stirring arm 141 and a second stirring arm 142. The first stirring arm 141 has a first mounting height H1; the second agitating arm 142 has a second mounting height H2 that is less than the first mounting height H1; wherein the first and second agitating arms 141 and 142 are configured to be detachably coupled to the pot cover 112 one at a time and assembled to the first driving mechanism 131.

In a state where the boom assembly 130 is in the upper working position (as shown in fig. 2), the first agitating arm 141 may be assembled with the first driving mechanism 131 in place for normal operation, and in a state where the boom assembly 130 is in the lower working position (as shown in fig. 8), the second agitating arm 142 may be assembled with the first driving mechanism 131 in place for normal operation.

As shown in fig. 2, the first agitating arm 141 may have a first mounting shoulder 143, and a vertical distance from a top surface of the first mounting shoulder 143 to the top surface of the first agitating arm 141 in a state where the first agitating arm 141 is connected to the pot body cover 112 may be defined as a first mounting height H1.

As shown in fig. 8, the second agitating arm 142 has a second mounting shoulder 144, and a vertical distance from a top surface of the second mounting shoulder 144 to the top surface of the second agitating arm 142 in a state where the second agitating arm 142 is coupled to the pot body cover 112 may be defined as a second mounting height H2.

It will be appreciated that since the first mounting height H1 of the first stirring arm 141 is greater than the mounting height of the second stirring arm 142, the first stirring arm 141 can be mounted in position with the first driving mechanism 131 in the state where the boom assembly 130 is in the upper working position, while the second stirring arm 142 cannot be mounted in position with the first driving mechanism 131 because of insufficient mounting height (as shown in fig. 3). That is, the boom assembly 130 in the upper working position is only provided for the first stirring arm 141 to be assembled, such that the first driving mechanism 131 drives the first stirring arm 141 to rotate.

Of course, it will also be appreciated that with the boom assembly 130 in the lower operating position, the second agitator arm 142 can be assembled with the first drive mechanism 131 since the lower operating position is lower than the upper operating position. Further, the vertical distance between the upper and lower working positions of the boom assembly 130 may be defined as a third height H3, the first mounting height H1 satisfying: greater than the sum of the second mounting height H2 and the third height H3. Therefore, instead, the first agitating arm 141 is too high in installation height, and the boom assembly 130 cannot be lowered to the lower working position in a state where the first agitating arm 141 is connected to the pot body cover 112. That is, the boom assembly 130 in the lower operating position is only used to rotate the second agitator arm 142 such that the first drive mechanism 131 drives the second agitator arm 142 to rotate.

It is understood that in other embodiments, the specific intended location reached by the boom assembly 130 and the mounting height of each agitator arm may be set accordingly. Therefore, a user can replace the corresponding stirring arm according to the preset position of the cantilever assembly 130, and switching of different stirring scenes is achieved.

Further, the cooking appliance 100 may further include a prompting device, and the prompting device may be configured to: the assembly error prompt message is issued in a state where the arm assembly 130 is in the upper working position and the second agitating arm 142 is connected to the pot body cover 112, and in a state where the arm assembly 130 is in the lower working position and the first agitating arm 141 is connected to the pot body cover 112. The assembly error prompt message can be a text prompt message or an acoustic and optical prompt message.

It can be understood that in the state that the cantilever assembly 130 is in the upper working position and the second stirring arm 142 is connected to the pot body cover 112, since the installation height of the second stirring arm 142 is not enough, at this time, the first driving mechanism 131 idles without load, so that the prompt device can send out the prompt message of assembly error; in the state where the first stirring arm 141 is connected to the pot body cover 112, the first driving mechanism 131 is pushed by the first stirring arm 141 and cannot reach the lower working position in the process where the arm assembly 130 moves downward to the lower working position, which may be understood as an abnormal (increased) load of the first driving mechanism 131, and thus, an assembly error notification message may be issued by the notification device.

Next, referring to fig. 4 and 5, the structure of the cantilever assembly 130 and the first drive mechanism 131 therein will be specifically described.

As shown in FIG. 4, the cantilever assembly 130 includes a viewing window 151, an upper housing 152, a first drive mechanism 131, a lower housing 153, a temperature sensor 154, and a sealing ring 155. The Temperature sensor 154 may be ntc (negative Temperature coefficient) sensor. Wherein, the sealing ring 155 is sleeved on the NTC, the NTC is fixed on the lower shell 153, when the cantilever assembly 130 is matched with the cooker body assembly 110, the sealing ring 155 plays a sealing role, and the NTC can realize the upper temperature measurement of the inner pot 113. The first drive mechanism 131 is fixed by the clamping action of the upper case 152 and the lower case 153.

More specifically, as shown in fig. 5, the first drive mechanism 131 includes a first motor 133, a motor carrier 162, a primary planet assembly 136, a secondary planet assembly, and a ring gear 163. The motor bracket 162 serves to support the first motor 133. The primary planetary assembly 136 includes a sun gear 161 fitted over an output shaft of the first motor 133, and a first planetary gear set engaged with the sun gear 161. The first planetary gearset particularly also includes a first planetary carrier and a plurality (3) of first planets. The sun gear 161 is in meshing engagement with the three first planet gears.

The secondary planet assembly comprises a second planet wheel set, the second planet wheel set specifically comprises a second planet wheel support and a plurality of second planet wheels, and the second planet wheels are in meshing transmission with the inner side teeth of the first planet wheel support.

The first drive 131 has different first 134 and second 135 outputs, the first 134 output being for mounting a first agitator arm 141 and the second 135 output being for mounting a second agitator arm 142.

After the first driving mechanism 131 is assembled, the rotation of the output shaft of the first motor 133 drives the sun gear 161 to rotate, and further drives the first-stage planetary assembly 136 and the second-stage planetary assembly 137 to transmit. The output end of the first motor 133 forms a first output end 134 and the output end of the final (secondary) planetary assembly forms a second output end, and as shown in fig. 4, the end surface of the second output end 135 surrounds the end surface of the first output end 134. Preferably, the end face of the first output end 134 is flush with the end face of the second output end 135. In other embodiments, the end surface of the first output end 134 may protrude beyond the end surface of the second output end 135.

The output speed of the output shaft of the first motor 133 completely depends on the motor characteristics (in this embodiment, a dc brushless motor is used, and the speed can be adjusted at 200 and 4000 rpm), the first stirring arm 141 can achieve the rapid stirring function, and the output shaft of the first motor 133 is designed to be hexagonal, and the top of the output shaft is in large round transition. The output structure of the second planet carrier in the secondary planet assembly 137 is a spline.

Correspondingly, it can be understood that the first stirring arm 141 is matched with the output shaft end of the first motor 133, and in the present embodiment, as shown in fig. 6, the mating end of the first stirring arm 141 is a polygonal groove, and the upper portion of the first stirring arm is excessively beveled; the second stirring arm 142 is matched with a spline of a second planet wheel support of the secondary planet assembly 137, the matching end of the second stirring arm 142 is a spline, and the upper portion of the second stirring arm is excessively beveled. The second stirring arm is driven by the planetary reduction mechanism after being reduced, so that the slow stirring function can be realized.

Next, referring to fig. 7, a process of mounting the first and second agitating arms 141 and 142 to the pot body cover 112 is explained. The first agitating arm 141 or the second agitating arm 142 is mounted to the pot body cover 112 through the rotating assembly 114.

The rotating assembly 114 includes a bracket 119, a rotating frame 117, and a sleeve 118. The steaming grid assembly can be fixed on the cooker body cover 112 by the support 119, the sleeve 118 is made of self-lubricating material, the sleeve 118 is fixed between the support 119 and the rotating frame 117, and the rotating frame 117 can rotate around the axis of the rotating frame 117. Taking the first stirring arm 141 as an example, the first stirring arm 141 is provided with a stop column 115, which can pass through the clearance groove on the rotating frame 117, when the first stirring arm is pushed to the bottom, the first stirring arm rotates for a certain angle in the opposite direction of the rotation of the motor, and then the first stirring arm is loosened, the stop column 115 is clamped on the stop column 116, at this time, the first stirring arm does not fall off, and the rotating frame 117 can rotate together with the first stirring arm 141. Similarly, the second agitating arm 142 may also be so mounted to the pot body cover 112.
