Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular, to an exhaust cover assembly, a cup cover assembly and a cooking machine. Background Art

[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged on the market. Generally for safety convenience, the cup cover assembly of the existing cooking machine is usually provided with air holes to communicate the cavity of the cooking cup with the external environment.

[0003] When the cooking machine heats and boils food materials, in order to prevent the slurry in the cooking cup from easily overflowing from the air holes, it can only boil at a low power, and the food materials cannot be fully boiled and emulsified, and the nutrition is insufficiently released; at the same time, during the subsequent high-speed stirring, the noise is relatively large, affecting the user experience.

[0004] Therefore, it is necessary to design an exhaust cover assembly that prevents overflow. Summary of the Utility Model

[0005] The present application provides an exhaust cover assembly, a cup cover assembly and a cooking machine, which can prevent overflow and reduce noise.

[0006] According to the first aspect of the embodiments of the present specification, an exhaust cover assembly is provided, which includes:

[0007] An exhaust bracket provided with an exhaust port thereon;

[0008] An exhaust cover provided with an exhaust hole thereon; and

[0009] A steam switch installed between the exhaust bracket and the exhaust cover, the steam switch including a baffle and a bimetallic deformation piece; when the set temperature is not reached, the baffle blocks the exhaust port, and when the set temperature is reached, the bimetallic deformation piece drives the baffle to move, so that the exhaust hole and the exhaust port are communicated. Thus, when the cooking machine heats and boils food materials and the temperature reaches the set temperature of the bimetallic deformation piece, the bimetallic deformation piece expands and drives the baffle to move, so that the exhaust hole is communicated with the exhaust port. At this time, rapid exhaust is carried out, and at the same time, the cold air outside the cooking cup and the hot air are in convection, reducing the temperature, reducing the generation of foam, and preventing overflow. When high-speed stirring is carried out later and the temperature does not reach the set temperature of the bimetallic deformation piece, the bimetallic deformation piece contracts and drives the baffle to move, so that the baffle blocks the exhaust port, achieving the effect of noise reduction.

[0010] Further, the baffle is provided with a ventilation port. After the set temperature is reached, the bimetallic deformation piece drives the baffle to rotate, so that the ventilation port is communicated with the exhaust port. Thus, the exhaust port is communicated with the exhaust hole through the ventilation port.

[0011] Further, the bimetallic strip is arranged in a spiral shape, with a fixing part provided on its inner circle and a rotating part provided on its outer circle; the fixing part is installed in the installation groove of the exhaust cover, and the rotating part is installed in the connection groove of the baffle. In this way, through the spiral structure design, the bimetallic strip can rotate to achieve relaxation or contraction when the temperature changes, and then drive the baffle to rotate, so as to close or connect the exhaust hole and the exhaust port.

[0012] Further, the exhaust cover is provided with a first limiting part and a second limiting part that cooperate with the rotating part, and the rotating part rotates between the first limiting part and the second limiting part. In this way, the rotation of the rotating part is restricted between the first limiting part and the second limiting part, preventing the bimetallic strip from rotating beyond a predetermined angle and causing unnecessary wear or looseness.

[0013] Further, the number and central angle of the ventilation openings and the exhaust ports are the same, and the central angle of each ventilation opening is less than or equal to the central angle between adjacent two ventilation openings;

[0014] wherein the maximum rotation angle of the bimetallic strip is equal to the central angle of one ventilation opening. In this way, it is ensured that the steam at each exhaust port can be discharged through the ventilation opening. At the same time, there is enough space between adjacent two ventilation openings to block the ventilation opening.

[0015] Further, the maximum central angle of the exhaust hole is γ, the central angle of the exhaust port is α, and the central angle between adjacent two exhaust ports is β, where 2α + β ≤ γ. In this way, the steam can be directly discharged upward along the vertical direction, reducing the movement path of the steam between the baffle and the exhaust cover.

[0016] Further, the baffle is provided with an upper fixing column and a lower fixing column that are symmetrically arranged up and down, the bottom of the exhaust cover is provided with a positioning groove that rotates in cooperation with the upper fixing column, and the exhaust bracket is provided with a groove that rotates in cooperation with the lower fixing column. In this way, it is ensured that the position of the baffle is stable when rotating, and it rotates around a fixed point, so as to realize that the ventilation opening and the exhaust port can be conducted.

[0017] Further, a stepped part is provided on the inner side of the exhaust cover, and a convex rib that cooperates with the stepped part is provided on the exhaust bracket;

[0018] The exhaust cover assembly further includes a lock catch and an elastic member, a limiting groove is provided on the exhaust bracket, and the elastic member applies an outward elastic force to the lock catch in the limiting groove, so that the lock catch is buckled with the stepped part. In this way, it is ensured that the lock catch and the stepped part are matched, and it helps the exhaust cover and the exhaust bracket to be tightly combined.

[0019] According to the second aspect of the embodiments of this specification, a cup lid assembly is provided, which includes the exhaust lid assembly, the cup lid, and the sealing ring described in the first aspect above. An exhaust passage is provided on the cup lid, the exhaust bracket passes through the exhaust passage, and the sealing ring is sleeved on the exhaust bracket and forms a seal with the cup lid. In this way, the tight fit between the cup lid and the exhaust lid assembly is ensured through the sealing ring. In addition, the sealing ring can also effectively prevent steam from leaking out from the connection between the cup lid and the exhaust lid assembly.

[0020] According to the third aspect of the embodiments of this specification, a cooking machine is provided, which includes the cup lid assembly described in the second aspect above and a cooking cup, and the exhaust passage is communicated with the cooking cup. In this way, steam is exhausted from the exhaust lid assembly through the exhaust passage to prevent overflow in the stirring cup.

[0021] The present application has the following beneficial effects: By providing a baffle in the exhaust lid and the exhaust bracket, the baffle is connected to the bimetallic deformation piece. When the cooking machine heats and boils the ingredients and the temperature reaches the set temperature of the bimetallic deformation piece, the bimetallic deformation piece expands and drives the baffle to move, so that the exhaust hole is communicated with the exhaust port. At this time, rapid exhaust occurs, and at the same time, the cold air outside the cooking cup and the hot air convect to reduce the temperature, reduce the generation of foam, and prevent overflow; when high-speed stirring is carried out later and the temperature does not reach the set temperature of the bimetallic deformation piece, the bimetallic deformation piece contracts and drives the baffle to move, so that the exhaust hole is sealed with the exhaust port, achieving the effect of noise reduction.

[0022] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit this specification. Brief Description of the Drawings

[0038] Here, in conjunction with the accompanying drawings, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a certain specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0040] Next, the embodiments of the present specification will be described in detail.

[0041] Refer to Figure 3-6As shown in the figure, this embodiment discloses an exhaust cover assembly 100, which includes an exhaust bracket 10, an exhaust cover 20, and a steam switch 30. An exhaust port 11 is provided on the exhaust bracket 10, and an exhaust hole 21 is provided on the exhaust cover 20. The steam switch 30 includes a baffle 31 and a bimetallic deformation piece 32, and the steam switch 30 is installed between the exhaust bracket 10 and the exhaust cover 20.

[0042] When the cooking machine heats and boils food materials and the temperature reaches the set temperature of the bimetallic deformation piece 32, the bimetallic deformation piece 32 expands and drives the baffle 31 to move, so that the exhaust hole 21 communicates with the exhaust port 11. At this time, rapid exhaust occurs, and at the same time, the cold air outside the cooking cup 400 convects with the hot air, reducing the temperature, reducing the generation of foam, and preventing overflow. When the temperature does not reach the set temperature of the bimetallic deformation piece 32, the bimetallic deformation piece 32 contracts and drives the baffle 31 to move, so that the baffle 31 blocks the exhaust port 11, achieving the effect of noise reduction. It should be noted that the movement mentioned here includes translation and rotation.

[0043] In one embodiment, driving baffles 31 are provided at both ends of the bimetallic deformation piece 32. When the cooking machine heats and boils food materials and the temperature reaches the set temperature of the bimetallic deformation piece 32, the bimetallic deformation piece 32 expands and drives the baffles 31 to translate to both sides, so that the exhaust hole 21 communicates with the exhaust port 11, opening the exhaust hole 21 to prevent overflow. When the temperature does not reach the set temperature of the bimetallic deformation piece 32, the bimetallic deformation piece 32 contracts and synchronously drives the baffles 31 to translate towards the center, so that the baffle 31 blocks the exhaust port 11, achieving the effect of noise reduction.

[0044] In this embodiment, a ventilation port 311 is provided on the baffle 31. After reaching the set temperature, the bimetallic deformation piece 32 drives the baffle 31 to rotate, so that the exhaust port 11 communicates with the exhaust hole 21 through the ventilation port 311.

[0045] Specifically, the pulping program includes a boiling stage and a whipping stage. In the boiling stage, the set temperature is set to 95°C. When the temperature rises to 95°C, the baffle 31 is fully opened, and the exhaust port 11 communicates with the exhaust hole 21 through the ventilation port 311. At this time, rapid exhaust occurs, and at the same time, the cold air outside the cup convects with the hot air, reducing the temperature, reducing the generation of foam, and preventing overflow. In the whipping stage, when the temperature is lower than 95°C, the baffle 31 blocks the exhaust port 11, and the exhaust port 11 is sealed, reducing the whipping noise.

[0046] In one embodiment, refer to Figure 7-10As shown in the figure, the bimetallic deformation piece 32 is arranged in a spiral shape. A fixing part 321 is provided on its inner ring, and a rotating part 322 is provided on its outer ring. The fixing part 321 is installed in the installation groove 22 of the exhaust cover 20. A convex block 314 is provided on the side of the baffle 31 facing the exhaust cover 20, and a connecting groove 3141 is provided on the convex block 314. The rotating part 322 is installed in the connecting groove 3141 of the baffle 31. Through the spiral structure design, the bimetallic deformation piece 32 can rotate to achieve relaxation or contraction when the temperature changes. When the temperature rises to the set temperature, the bimetallic deformation piece 32 rotates and relaxes, and drives the baffle 31 to rotate, so that the air vent 311 on the baffle 31 is communicated with the exhaust port 11. At this time, the exhaust port 11 is communicated with the exhaust hole 21 and exhausts quickly. At the same time, the cold air outside the cup convects with the hot air, reducing the temperature, reducing the generation of foam, and preventing overflow. When the temperature is lower than the set temperature, the bimetallic deformation piece 232 does not deform. At this time, the baffle 31 blocks the exhaust port 11, and the exhaust port 11 is sealed, reducing the whipping noise.

[0047] In addition, when the temperature changes from higher than the set temperature to lower than the set temperature, the bimetallic deformation piece 32 rotates and contracts in the direction opposite to relaxation, and drives the baffle 31 to rotate. The baffle 31 blocks the exhaust port 11, and the exhaust port 11 is sealed.

[0048] In order to prevent the bimetallic deformation piece 32 from rotating beyond a predetermined angle and causing unnecessary wear or looseness, a first limiting part 23 and a second limiting part 24 are provided on the exhaust cover 20 and cooperate with the rotating part 322. The rotating part 322 rotates between the first limiting part 23 and the second limiting part 24. That is, the convex block 314 is limited to rotate between the first limiting part 23 and the second limiting part 24.

[0049] The sum of the angles between the first limiting part 23 and the second limiting part 24 is equal to the sum of the included angles between the exhaust hole 21 and the adjacent exhaust holes 21. In this embodiment, the angle between the first limiting part 23 and the second limiting part 24 is 90°.

[0050] In this embodiment, the bimetallic deformation piece 32 is made of two layers of metals with different expansion coefficients. After the temperature reaches the set temperature, it will drive the baffle 31 to rotate, so that the exhaust hole 21 is communicated with the exhaust port 11. The structure is simple and easy to implement.

[0051] The deformation temperature of the above bimetallic deformation piece 32 depends on the expansion coefficients of the bimetallic sheet and the number of spiral layers, etc. Specifically, the set temperature at which the bimetallic deformation piece 32 deforms can be adjusted in combination with the working state of the cooking machine.

[0052] The expansion and contraction directions of the bimetallic deformation piece 32 can adjust the helical angle according to the required temperature range. In this embodiment, when the bimetallic deformation piece 32 rotates counterclockwise, it contracts along the spiral direction to close the exhaust port 11, and when it rotates clockwise, it expands along the spiral direction to open the exhaust port 11. In this embodiment, the temperature range for the bimetallic deformation piece 32 to be fully opened is 95-100°C.

[0053] The number and central angle of the air holes 311 and the exhaust holes 11 are the same to ensure that the steam from each exhaust hole 11 can be discharged through the air holes 311. The central angle of each air hole 311 is less than or equal to the central angle between two adjacent air holes 311, wherein the maximum rotation angle of the bimetallic deformation sheet 32 is equal to the central angle of one air hole 311, thus ensuring that there is enough space between two adjacent air holes 311 to block the air holes 311.

[0054] Reference Figure 4-5 As shown, the maximum central angle of the exhaust hole 21 is γ, the central angle of the exhaust port 11 is α, and the central angle between two adjacent exhaust ports 11 is β, wherein 2α+β≤γ, so that the steam can be directly discharged upward in the vertical direction, reducing the moving path of the steam between the baffle 31 and the exhaust cover 20. When α+β=90°, 0<β≤45°, 45°≤α<90°, wherein in this embodiment α=50°, β=40°, γ=130°.

[0055] The baffle plate 31 is provided with an upper fixed column 312 and a lower fixed column 313 which are symmetrically arranged up and down. The bottom of the exhaust cover 20 is provided with a positioning groove 25 which is rotatably matched with the upper fixed column 312. The exhaust bracket 10 is provided with a groove 12 which is rotatably matched with the lower fixed column 313 to ensure that the baffle plate 31 is in a stable position when rotating and rotates around a fixed point, thereby realizing that the air vent 311 and the exhaust port 11 can be connected.

[0056] Reference Figure 14 As shown, a step portion 26 is provided on the inner side of the exhaust cover 20, and a ridge 13 that cooperates with the step portion 26 is provided on the exhaust bracket 10. The ridge 13 provides positioning or cooperation for the exhaust cover 20 installed on the exhaust bracket 10, thereby helping the exhaust cover 20 to be tightly combined with the exhaust bracket 10.

[0057] Furthermore, the exhaust cover assembly 100 further includes a lock 40 and an elastic member 50. The exhaust bracket 10 is provided with a limiting groove 14. The elastic member 50 applies an outward elastic force to the lock 40 in the limiting groove 14, so that the lock 40 is engaged with the step portion 26 to ensure that the exhaust cover 20 will not loosen or fall off during use. At the same time, it also helps the ridge 13 to abut against the correct position of the step portion 26 to ensure the matching of the lock 40 and the step portion 26.

[0058] Reference Figure 1-2As shown, the present application also discloses a cup lid assembly, which includes an exhaust lid assembly 100, a cup lid 200, and a sealing ring 300. An exhaust passage 201 is provided on the cup lid 200. The exhaust bracket 10 passes through the exhaust passage 201. The sealing ring 300 is sleeved on the exhaust bracket 10 and forms a seal with the cup lid 200 to ensure the tight fit between the cup lid 200 and the exhaust lid assembly 100. In addition, the sealing ring 300 can also effectively prevent steam from leaking out from the connection between the cup lid 200 and the exhaust lid assembly 100.

[0059] The present application also discloses a cooking machine, which includes the above cup lid assembly and a cooking cup 400. The exhaust passage 201 is communicated with the cooking cup 400.

[0060] In this embodiment, when the cooking machine is working, when it starts to heat up to 50 - 85 degrees Celsius, the cooking machine starts to stir at a high speed. When the food in the cooking cup 400 is crushed, as Figure 11 shown, the exhaust port 11 and the ventilation port 311 are staggered, the exhaust bracket 10 is in a sealed state, closing the exhaust port 11, so that the ingredients will not overflow, and the working noise of the cooking machine during crushing is small.

[0061] When reheating starts after crushing, when the temperature in the cooking cup 400 reaches 90 degrees Celsius, steam starts to be generated in the cooking cup 400. The steam enters the exhaust port 11 from the exhaust passage 201. When the baffle 31 and the bimetallic deformation piece 32 blocking the exhaust port 11 reach the set temperature, the bimetallic deformation piece 32 expands and drives the baffle 31 to move, as Figure 12-13 shown, the exhaust port 11 coincides with the ventilation port 311, the exhaust bracket 10 is in an open state, opening the exhaust port 11 to prevent overflow.

[0062] The present application also discloses an embodiment of the installation of the exhaust lid assembly 100: First, install the fixed part 321 end of the inner circle of the bimetallic deformation piece 32 in the installation groove 22 on the exhaust lid 20; Second, insert the connection groove 3141 on the baffle 31 into the rotating part 322 of the outer circle of the bimetallic deformation piece 32, and at the same time, the upper fixing column 312 on the baffle 31 cooperates with the positioning groove 25 on the exhaust lid 20; Third, install the exhaust bracket 10 on the exhaust lid 20, and the installation is completed. When disassembling, press the lock catch 40 on the exhaust bracket 10 and operate in the reverse direction of the installation path to disassemble.
