Description

Technical Field

[0001] The utility model relates to the field of cooking, and particularly to a seasoning conveying device and a cooking appliance. Background Art

[0002] The traditional seasoning conveying method is to convey the seasoning from the inlet to the outlet through a seasoning pump. In order to prevent the backflow of the seasoning at the inlet and the dripping of the seasoning at the outlet, a check valve is added at the inlet, and a check valve and a duckbill valve are added at the outlet. This solution results in a relatively complex structure. The internal structure of the check valve is complex. After the check valve is stuck due to the residue or impurity of the seasoning inside, the check valve fails, and the liquid seasoning drips when it is stationary, affecting the seasoning accuracy and use. In addition, the traditional duckbill valve has a poor anti-backflow effect and is greatly affected by hardness, and the use process is unstable. In addition, during continuous swinging and vibration, due to the volume change inside the pipeline, it is easy to cause liquid dripping. Summary of the Utility Model

[0003] The main purpose of the present utility model is to provide a seasoning conveying device and a cooking appliance to solve the problem of easy liquid dripping in the existing seasoning conveying device.

[0004] To achieve the above object, according to one aspect of the present utility model, a seasoning conveying device is provided, including a conveying pipeline, a pump body, and a valve. The pump body is arranged on the conveying pipeline and drives the seasoning to be transported in the conveying pipeline. The valve is arranged at least at one of the inlet end, the outlet end, or the middle section of the conveying pipeline. The valve includes a valve body and a flexible member. The valve body is connected to the conveying pipeline and has a channel. The flexible member is arranged in the channel and has a closed state of blocking the channel and an open state of opening the channel. The flexible member deforms under the action of the seasoning and switches to the open state.

[0005] Further, the pump body is a bidirectional driving pump, and the bidirectional driving pump can drive the seasoning to be conveyed from the inlet end to the outlet end of the conveying pipeline during feeding, and can drive the seasoning in the conveying pipeline to be conveyed from the outlet end to the inlet end after feeding.

[0006] Further, the flexible member includes a plurality of sub-components, and the sub-components are sequentially arranged along the circumference of the channel to form a multi-petal structure. When the flexible member is in the open state, a gap for the seasoning to pass through is formed between the sub-components.

[0007] Further, when the flexible member is in the closed state, the surface of the flexible member is a curved surface.

[0008] Further, the center of the flexible member protrudes in a direction away from the channel.

[0009] Further, the center of the flexible member is recessed inwardly with respect to the channel.

[0010] Furthermore, the flexible member includes a plurality of sub-components, which are sequentially arranged along the circumferential direction of the channel to form a gap, and the size of the gap first decreases and then increases with the deformation of the flexible member.

[0011] Furthermore, there are a plurality of valves. The valves include: a first valve located at the inlet end and / or the outlet end of the conveying pipeline, and each sub-component converges at the center of the flexible member; a second valve located at the outlet end and / or the inlet end of the conveying pipeline, and each sub-component converges at the center of the flexible member, and there is a through-hole at the center of the flexible member, and the through-hole communicates with the gap.

[0012] Furthermore, the gap includes a plurality of straight slits intersecting at the same place.

[0013] Furthermore, when the flexible member is in the closed state, the surface of the flexible member is a plane perpendicular to the axis of the channel.

[0014] Furthermore, the valve includes a joint valve. The valve body of the joint valve is connected to the inlet end of the conveying pipeline and has an external joint for connecting to an external pipeline, and the flexible member of the joint valve is arranged in the valve body.

[0015] Furthermore, the valve body of the joint valve includes a first sub-body part and a second sub-body part. The first sub-body part is connected to the inlet end of the conveying pipeline, the second sub-body part has an external joint, the first sub-body part and the second sub-body part are butted to form a channel, and the flexible member is clamped between the first sub-body part and the second sub-body part.

[0016] According to another aspect of the present invention, there is provided a cooking appliance, including the above-mentioned seasoning conveying device.

[0017] Applying the technical solution of the present invention, by providing a valve, and the valve adopts the method of arranging a flexible member in the valve body. Since the flexible member itself can undergo a certain deformation, the flexible member can deform under the action of the seasoning pressure in the valve body, and then realize the transformation from blocking the channel to opening the channel, so as to achieve the effect of discharging the seasoning. When the seasoning conveying is completed, the pressure of the seasoning disappears, and the flexible member can automatically or be assisted to the closed state under the action of its own elasticity. And because of the elasticity of the flexible member, the flexible member can bear a certain pressure, which can effectively prevent liquid backflow, thus avoiding the situation of liquid dripping when no material is discharged, achieving the effects of stable liquid conveying and anti-dripping, ensuring the accuracy and reliability of material discharging, and even during continuous swinging and vibration, liquid dripping will not occur. Moreover, in this embodiment, since only a valve needs to be set, the number of parts is reduced, and unstable parts are eliminated, and the reliability of the entire seasoning conveying system is greatly improved.

[0030] To solve the problem of poor backflow prevention effect in the prior art, the present utility model provides a seasoning conveying device and a cooking appliance, wherein the cooking appliance includes the following seasoning conveying device.

[0031] Embodiment 1

[0032] As Figures 1 to 4 shown, a seasoning conveying device includes a conveying pipeline 10, a pump body 20, and a valve 30. The pump body 20 is arranged on the conveying pipeline 10 and drives the seasoning to be transported in the conveying pipeline 10. The valve 30 is arranged at least at one of the inlet end, the outlet end, or the middle section of the conveying pipeline 10. The valve 30 includes a valve body 31 and a flexible member 32. The valve body 31 is connected to the conveying pipeline 10 and has a passage. The flexible member 32 is arranged in the passage and has a closed state of blocking the passage and an open state of opening the passage. The flexible member 32 deforms under the action of the seasoning and switches to the open state.

[0033] In this embodiment, by providing the valve 30, and the valve 30 adopts the method of arranging the flexible member 32 in the valve body 31. Since the flexible member 32 itself can undergo a certain deformation, the flexible member 32 can deform under the action of the seasoning pressure in the valve body 31, and then realize the deformation from blocking the passage to opening the passage, so as to achieve the effect of discharging the seasoning. When the seasoning conveying is completed, the pressure of the seasoning disappears, and the flexible member 32 can automatically or assist to close under its own elastic action. And because of the elasticity of the flexible member 32, the flexible member 32 can bear a certain pressure, which can effectively prevent the liquid from flowing back, thus avoiding the situation of liquid dripping when no material is discharged, achieving the effects of stable liquid conveying and anti-dripping, ensuring the accuracy and reliability of material discharging, and even during continuous swinging and vibration, it will not cause liquid dripping. Moreover, in this embodiment, since only the valve 30 needs to be set, the number of parts is reduced, and unstable parts are cancelled, and the reliability of the entire seasoning conveying system is greatly improved.

[0034] It should be noted that the seasoning conveying device of this embodiment is mainly aimed at liquid materials. Of course, it can also be applied to granular materials. This embodiment takes the case where valves 30 are arranged at the inlet end and the outlet end of the conveying pipeline 10 as an example for illustration. Of course, the valve 30 can also be arranged only at one of the inlet end and the outlet end; or a valve 30 can also be arranged in the middle section of the conveying pipeline 10, that is, the section between the inlet end and the outlet end. At this time, the valve 30 can be on the input side of the pump body 20, or on the output side of the pump body 20, or both sides can be arranged.

[0035] The pump body 20 of this embodiment adopts a bidirectional drive pump, that is, the pump body 20 has driving forces in two directions, forward and reverse, so that the seasoning can be conveyed in the conveying pipeline 10 in two directions as required. In this way, when in use, when feeding, the bidirectional drive pump can drive the seasoning to be conveyed from the inlet end of the conveying pipeline 10 to the outlet end, so as to achieve feeding. After feeding, the bidirectional drive pump can drive the seasoning in the conveying pipeline 10 to be conveyed from the outlet end to the inlet end, so that there is a certain empty pipe between the pump body 20 and the outlet end of the conveying pipeline 10, thus avoiding excessive pressure at the seasoning outlet end and causing liquid dripping during the pressure release process.

[0036] Based on the above bidirectional conveying setting method, during the seasoning conveying process, the conveying and feeding time of the pump body 20 is controlled according to the amount of feeding. The detailed process is as follows: receive the feeding instruction, start the pump body 20, wait for the feeding time to end, close the pump body 20, start the pump body 20 in reverse, wait for the reverse time to end, and then close the device. After feeding, this embodiment provides a certain anti-pumping time T1 to ensure that there is a certain empty pipe in a part of the pipeline behind the pump, thus avoiding excessive pressure at the seasoning outlet pipe and causing liquid dripping during the pressure release process. In addition, during the feeding process, due to the anti-pumping effect, on the basis of the feeding time, a certain time compensation T2 needs to be added to the feeding time for the seasoning. There is a certain correlation between T2 and T1 according to the situation of the seasoning.

[0037] In this embodiment, the flexible member 32 includes a plurality of sub-components. The sub-components form the surface that blocks the channel. The sub-components are sequentially arranged along the circumference of the channel and form a multi-petal structure. More specifically, the sub-components are generally fan-shaped. The straight edges of all the fan-shaped components are butt-jointed in sequence to form a corresponding circular structure with the circular channel. Among them, the apex angles of each fan-shaped component are located at the center of the flexible member 32, that is, on the central axis of the channel. The positions of the straight edges of each fan-shaped component close to the arc edge are connected together to form an integral component. When feeding, the pressure of the seasoning acts on each sub-component, and each sub-component will deform, causing its straight edges to move away from each other, thus forming a gap 321 for the seasoning to pass through. At this time, the flexible member 32 is in an open state, and feeding can be achieved. Of course, the specific shape of the sub-component is not limited to the form described in this embodiment above. When the shape of the channel changes, the shape of the sub-component can be adjusted accordingly, as long as it can ensure that the sub-components can approach or move away from each other according to the feeding situation, so as to change the state of the gap 321 to achieve blocking and feeding.

[0038] It should be noted that the gap 321 is not only formed in the open state. Even when the flexible member 32 is in the closed state, a gap 321 of a certain size can be formed. It's just that the size of the gap 321 is different in the open state and the closed state. As long as it is ensured that the gap 321 in the open state allows the seasoning to pass through, and the gap 321 in the closed state does not allow the seasoning to pass through.

[0039] Preferably, in this embodiment, when the flexible member 32 is in the closed state, the surface of the flexible member 32 is a curved surface. That is to say, when no material is being fed, the surface of the flexible member 32 is not a plane perpendicular to the central axis of the channel. In this way, on the one hand, when the pump body is closed, there is still some seasoning left in the pipeline, causing a certain pressure on the flexible member 32, so that the flexible member 32 closes. Thus, it can not only achieve the effect of preventing dripping, but also effectively prevent liquid backflow, greatly improving the reliability of the seasoning conveying device. On the other hand, when the seasoning is being conveyed, the increased pressure of the seasoning causes the curved surface to deform and switch to the open state. The curved surface can more effectively guide the conveyance of the seasoning compared to a plane, reducing the resistance to conveyance at the valve 30, thereby reducing impact and vibration.

[0040] It should be noted that in this embodiment, the center of the flexible member 32 can protrude away from the channel or be recessed inwardly towards the inside of the channel, enabling it to withstand a certain internal pressure in the closed state, preventing the seasoning from dripping and flowing back. Thus, both the flexible member 32 protruding away from the channel and the flexible member 32 recessed inwardly towards the inside of the channel can achieve the effects of anti-backflow and anti-dripping, and their effects are better than those of traditional duckbill valves. However, considering a better anti-dripping effect, this embodiment preferably adopts the method of recessing inwardly towards the inside of the channel. As Figure 2 shown, after the material feeding is completed, since there is still a certain amount of material remaining in the channel, this part of the material can still exert a certain pressure on the flexible member 32. This pressure is not sufficient to cause the flexible member 32 to switch to the open state. On the contrary, this pressure will cause the flexible member 32 to have a tendency to protrude outward from the channel. This tendency will cause the flexible member 32 to deform from the arc state recessed into the channel to a plane state completely perpendicular to the channel axis. During this deformation, the size of the gap 321 will decrease, which leads to a further increase in the sealing effect of the flexible member 32, and further improves the sealing and anti-dripping effects.

[0041] Of course, when setting the flexible member 32, the method of making the center of the flexible member 32 protrude away from the channel can also be adopted. Although it is better than the duckbill valve, compared with the above-mentioned method of recessing inwardly, its anti-backflow effect is reduced. Or the method of making one side of the flexible member 32 recessed into the channel and the other side protruding out of the channel can be adopted.

[0042] The process of the flexible member 32 in this embodiment switching from the closed state to the open state is as follows: When a certain pressure is applied to the flexible member 32, the gap 321 between the sub-components gradually decreases, and the flexible member 32 remains in the closed state. At this time, the flexible member 32 can prevent the liquid in the pipeline from flowing back and dripping, playing the role of anti-backflow and sealing to prevent dripping. When the pressure of the seasoning continues to increase, causing the flexible member 32 to be subjected to a greater force, due to the certain flexibility of the flexible member 32, the flexible member 32 continues to deform. Since the edge of the flexible member 32 is connected to the valve body 31, and the positions of the straight edges of the sub-components close to the arc side are connected to each other, the degree of deformation that the edge of the flexible member 32 can undergo is relatively small. However, since the center of the flexible member 32 is the intersection of the sub-components, the degree of deformability at this center is relatively large. Therefore, at this time, a large deformation occurs at the center of the flexible member 32, and this part switches from the concave state to the convex state. At this time, the gap at the center of the flexible member 32 increases, and the flexible member 32 switches to the open state. For the edge of the flexible member 32, it cannot bulge outward, so the size of the gap here can generally only be reduced to a certain extent, but this does not affect the seasoning passing through the increased gap at the center of the flexible member 32, thereby achieving material feeding. After the material feeding is completed, the center of the flexible member 32 can return to the initial closed state under the action of its own elasticity.

[0043] It should be noted that due to the flexibility of the flexible member 32, the valve 30 is reversible and can still be used normally after being reversed.

[0044] As Figure 3 and Figure 4 As shown, in this embodiment, there are multiple valves 30. All valves 30 include a first valve and a second valve. The first valve is located at the inlet end and / or the outlet end of the conveying pipeline 10. On the first valve, the sub-components intersect at the center of the flexible member 32, thereby obtaining a stronger anti-backflow effect. The second valve is located at the outlet end and / or the inlet end of the conveying pipeline 10. On the second valve, the sub-components intersect at the center of the flexible member 32. Different from the first valve, the center of the flexible member 32 of the second valve has a through-hole 322, and the through-hole 322 is communicated with the gap 321, so as to be able to adjust the spraying direction of the seasoning and prevent the situation that the spraying direction of the seasoning at the outlet is out of control due to uneven cutting or uneven force. Considering that the outlet end of the conveying pipeline 10 is the position where the seasoning is discharged, and the inlet end is generally only the position where the seasoning enters, in this embodiment, the above-mentioned first valve is set at the inlet end as the inlet valve, and the second valve is set at the outlet end as the outlet valve, so as to ensure that the spraying of the seasoning can be controlled during material feeding. Of course, the same type of valve can also be set at the inlet end and the outlet end; or the second valve can be set at the inlet end and the first valve can be set at the outlet end.

[0045] Optionally, the setting form and setting number of the gap 321 can be adjusted accordingly as needed, and it can be set as one or multiple, and the shape can be straight, cross, or wave-shaped. In this embodiment, the gap 321 includes multiple straight gaps intersecting at the same place, that is, the gap extends in all directions along the center of the flexible member 32, so that the flexible member 32 can withstand greater pressure without deformation when it is in a closed state, thereby achieving better anti-return and anti-drip effects. Preferably, the gap in this embodiment adopts a cross shape, which has better anti-return and anti-drip effects.

[0046] Embodiment 2

[0047] What is different from the first embodiment is that in this embodiment, when the flexible member 32 is in a closed state, the surface of the flexible member 32 is a plane perpendicular to the axis of the channel, that is, the flexible member 32 neither protrudes away from the channel nor is recessed into the inner side of the channel, but is perpendicular to the conveying direction of the seasoning, and has the same working principle as the second half of the flexible member 32 of the first embodiment, that is, in the closed state, the flexible member 32 blocks the channel and closes it. When the pressure increases, the flexible member 32 deforms, so that each sub-component deforms in the direction of protruding from the channel, so that the gap 321 between the sub-components opens, and the valve 30 opens, thereby completing the seasoning delivery. In this setting, the valve 30 can also play a non-return and anti-drip effect.

[0048] Embodiment 3

[0049] The difference from the first embodiment is that the valve 30 of this embodiment includes a connector valve.

[0050] like Figure 5 and Figure 6 As shown, specifically, the valve 30 of this embodiment includes a joint valve, that is, Figure 5 and Figure 6 The valve above the intermediate material tank 40. As for the joint valve, it not only has the function of controlling the opening and closing of the valve, but also has the function of being connected to an external pipeline. Specifically, the valve body 31 of the joint valve is connected to the inlet end of the delivery pipeline 10, and the valve body 31 of the joint valve has an external joint 323 for connecting to an external pipeline. In this way, the joint valve can be connected to the external pipeline through the external joint 323. Since the joint valve has the functions of stable liquid delivery and anti-drip as described in Example 1, it can avoid the dripping of seasoning during plugging and unplugging, thereby improving the user experience and ensuring the accuracy of material discharge.

[0051] The valve body 31 of the joint valve in this embodiment includes a first sub-body part 311 and a second sub-body part 312. The first sub-body part 311 is connected to the inlet end of the conveying pipeline 10. The second sub-body part 312 has an external joint 323. The first sub-body part 311 and the second sub-body part 312 are arranged separately. When in use, docking the two can form a channel between them. At the same time, the flexible member 32 is clamped between the first sub-body part 311 and the second sub-body part 312, so that the flexible member 32 can be fixed in the channel, enabling the flexible member 32 to fully play the role of controlling the on-off.

[0052] The diameter of the channel in this embodiment is larger than the diameter of the conveying pipeline 10. That is to say, both the first sub-body part 311 and the second sub-body part 312 include a large-diameter section and a small-diameter section. Among them, the large-diameter sections of the two are docked with each other. The sizes of the two large-diameter sections can be different, and they can be connected by means such as clamping or threading. After the two large-diameter sections are docked, a channel can be formed. Since a step surface is naturally formed between the large-diameter section and the small-diameter section, when the two large-diameter sections are docked, the step surface of one sub-body part and the end of the large-diameter section of the other sub-body part can clamp the flexible member 32, thus realizing the effect of fixing the flexible member 32 in the channel. Due to the relatively large inner diameter of the conveying pipeline 10, the gap 321 of the flexible member 32 in this embodiment can be opened only at the position aligned with the conveying pipeline 10, that is, a cross-shaped gap 321 is provided at the center position of the flexible member 32, so that the gap 321 can cooperate with the conveying pipeline 10. The small-diameter sections of the first sub-body part 311 and the second sub-body part 312 can cooperate with the pipeline. The small-diameter section of the first sub-body part 311 can cooperate with the conveying pipeline 10 to realize the insertion of the conveying pipeline 10, etc., and the small-diameter section of the second sub-body part 312 can form an external joint 323 to connect with an external pipeline.

[0053] The flexible member 32 in this embodiment adopts a planar setting form, that is, when the flexible member 32 is in the closed state, the surface of the flexible member 32 is a plane. Of course, the setting method of the curved surface in Embodiment 1 can also be adopted.

[0054] Of course, the specific structural form of the joint valve can also adopt other structures. For example, on the basis of the valve 30 in Embodiment 1, the flexible member 32 is not arranged at the end of the valve body 31, but is arranged inside the valve body 31. The valve body 31 is divided into two sections, a first section and a second section, on both sides of the position where the flexible member 32 is located. Among them, the first section can be connected to the conveying pipeline 10, and the second section can form an external joint 323, so as to realize the function of controlling the on-off and connecting the pipeline.

[0055] It should be noted that in actual use, there is no conflict between the joint valve in Embodiment 3 and the valve 30 in Embodiment 1, and they can be set at the same time. For example Figure 5 and Figure 6In the setting method, a joint valve in the third embodiment is provided at the inlet end where the conveying pipeline 10 extends out of the material tank 40, and a valve 30 in the first embodiment is provided at the outlet end where the conveying pipeline 10 extends into the material tank 40.

[0056] It should be noted that the multiple in the above embodiments refers to at least two.

[0057] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0058] 1. Solved the problem that the liquid dripping easily occurs in the existing seasoning conveying device;

[0059] 2. Improved the anti-backflow effect by improving the structure of the seasoning conveying device, solved the problem of liquid dripping, and simplified the structure of the seasoning conveying device at the same time;

[0060] 3. The setting of the flexible member plays a better role in sealing and preventing liquid dripping.
