Description

Technical Field

[0001] The utility model relates to the technical field of beverage cooking equipment, and particularly relates to a housing assembly, a weighing module and a beverage cooking equipment. Background Art

[0002] To extract a cup of high-quality coffee, many elements need to be considered, and one of the more influential factors is the coffee powder. The ratio of coffee powder to water will directly affect the extraction effect of coffee, which is usually referred to as the extraction rate. To make better coffee, baristas have relatively high requirements for the extraction rate.

[0003] Currently, coffee machines on the market, such as the widely used fully automatic coffee machines, generally use a time control method to control the amount of coffee powder, that is, to control the weight of the coffee powder by controlling the working time of the grinding component therein. As is well known, there are single-origin coffee beans and blended coffee beans, but there are obvious differences between them. The size and dimensions of the coffee beans are inconsistent, and the roasting degree of the coffee beans is inconsistent, resulting in different hardness of the coffee beans themselves. This leads to a certain error in the method of controlling the weight of the coffee powder by controlling the working time of the grinding component, resulting in unstable quality of the extracted coffee.

[0004] There is a coffee machine that presets a weighing module. The weighing module can accurately measure the weight of the ground powder, thus ensuring uniform powder amount and stable quality of the extracted coffee. However, the existing weighing module has the disadvantage of complex structure, increasing the forming difficulty and disassembly difficulty. Summary of the Utility Model

[0014] Optionally, the part of the second vertical plate outside the two second slots forms a connecting part, and the connecting part is detachably connected to the corresponding top seat or the side wall of the top seat.

[0015] Optionally, a slot is recessed on one longitudinal side of the base for the insertion and connection of the insertion protrusion of the carrier to be installed, and a relief groove is locally recessed on the other longitudinal side of the base corresponding to the slot, and the relief groove is longitudinally penetrated with a threaded hole communicating with the slot;

[0016] The housing assembly further includes a screwing member, the screwing member is threadedly connected to the threaded hole and extends into the slot to connect and fix the insertion protrusion.

[0017] Optionally, two first slots are spaced apart at the position of the first vertical plate corresponding to the relief groove, and the part of the first vertical plate between the two first slots is folded towards the inside of the receiving cavity to form a first flanging, and the first flanging extends into the relief groove and presses against the screwing member.

[0019] Optionally, a reinforcing rib is protruded in the relief groove of the base, the reinforcing rib is at least arranged on one side of the threaded hole and is connected to at least three side walls of the relief groove.

[0041] See also Figures 1 to 6 The utility model provides a housing assembly 100, which can be used in a weighing module, and the weighing module can be used in a beverage preparation device.

[0042] It should be noted that, for ease of understanding, in the following embodiments, the shell assembly 100 is described by taking the vertical, horizontal and longitudinal directions arranged in pairs as an example. In actual application, the vertical direction may correspond to the direction of gravity, and then the vertical direction has an upward direction and a downward direction facing each other; the horizontal and longitudinal directions correspond to two directions that are substantially perpendicular on a horizontal plane.

[0043] Specifically, the shell assembly 100 includes a base 110, a support seat 120 and a top seat 130; the support seat 120 includes a first vertical plate 121 and two second vertical plates 122 respectively arranged on both sides of the first vertical plate 121, and the two second vertical plates 122 are both bent and extended from the first vertical plate 121 along the longitudinal direction to enclose together with the first vertical plate 121 to define a receiving cavity that is open at both vertical ends and one longitudinal side; the top seat 130 is connected and fixed to the support seat 120, and the cover is arranged at the top opening of the receiving cavity; the base 110 is connected and fixed to the support seat 120, and the cover is arranged at the bottom opening of the receiving cavity; wherein, the first vertical plate 121 and the two second vertical plates 122 are formed by a plate material through secondary bending processing.

[0044] In the technical solution provided by the present utility model, the base 110 forms a bottom support for installing components such as the support seat 120 and the base 110. The top seat 130 forms a top support for installing some components of the weighing module. The accommodating cavity formed by the support seat 120 is for installing the remaining components of the weighing module. The support seat 120 is directly formed by bending a same sheet material twice to form a first vertical plate 121 and two second vertical plates 122. On the one hand, it helps to simplify the forming process of the first vertical plate 121 and the second vertical plates 122 and saves the disassembly and assembly operations of the three; on the other hand, it helps to increase the connection strength between the first vertical plate 121 and the second vertical plates 122 to a certain extent; in addition, it also helps to make the shape enclosed by the first vertical plate 121 and the second vertical plates 122 more adapted to the shapes of the base 110 and the top seat 130, and increases the matching degree among the top seat 130, the base 110 and the support seat 120. By improving the housing assembly 100, the present application reduces the forming difficulty and disassembly difficulty of the overall weighing module, and improves the structural matching degree and compactness among the components to a certain extent.

[0045] It can be understood that the first vertical plate 121 extends and spreads out roughly along the vertical and horizontal directions, and the second vertical plates 122 extend and spread out roughly along the vertical and longitudinal directions, so that the accommodating cavity penetrates longitudinally and forms a top opening and a bottom opening.

[0046] Among them, the top opening is adapted to be detachably connected to the top seat 130. Specifically, for example, the top seat 130 is integrally supported on the top of the support seat 120, and the bottom end of the top seat 130 just covers the top opening of the accommodating cavity. Or as Figures 3 to 4 shown, at least the lower section of the top seat 130 is inserted and fixed in the accommodating cavity. On the one hand, the mutual insertion setting of the top seat 130 and the support seat 120, that is, the outer wall of the top seat 130 and the inner cavity wall of the accommodating cavity are slidably connected, enables the mutual insertion guidance between the top seat 130 and the support seat 120, and makes it easier for the top seat 130 and the support seat 120 to be installed in place. On the other hand, since the first vertical plate 121 and the two second vertical plates 122 are formed by bending a same sheet material, by inserting at least the lower section of the top seat 130 into the accommodating cavity, the at least lower section of the top seat 130 can be used to form transverse and longitudinal supports for the first vertical plate 121 and the two second vertical plates 122, which helps to maintain the shapes of the first vertical plate 121 and the two second vertical plates 122.

[0047] The bottom opening is adapted to be detachably connected to the base 110. Specifically, for example, the first vertical plate 121 and the two second vertical plates 122 in the support seat 120 are directly supported on the top of the base 110, and the top of the base 110 just covers the bottom opening of the accommodating cavity. Or as Figures 3 to 4As shown, at least the upper section of the base 110 is inserted and fixed in the receiving cavity. Similarly to the above, on the one hand, the mutual insertion arrangement of the base 110 and the support base 120, that is, the outer wall of the base 110 and the inner cavity wall of the receiving cavity are slidably connected, enabling the mutual insertion guidance between the base 110 and the support base 120, and making it easier for the base 110 and the support base 120 to be installed in place. On the other hand, since the first vertical plate 121 and the two second vertical plates 122 are formed by bending the same sheet material, by inserting at least the upper section of the base 110 into the receiving cavity, the at least upper section of the base 110 can be used to form lateral and longitudinal supports for the first vertical plate 121 and the two second vertical plates 122, which helps to maintain the shapes of the first vertical plate 121 and the two second vertical plates 122.

[0048] It should be noted that the structures of the two second vertical plates 122, such as dimensions, shapes, etc., can be set the same, and the two are generally symmetrically arranged about the vertical center line of the first vertical plate 121; or the structures of the two second vertical plates 122 are set differently, that is, at least in terms of dimensions, shapes, etc., they are set to be partially different or completely different. However, for the sake of easy understanding and to make the supporting effect of the housing assembly 100 more balanced and stable during actual application, in the following embodiments, the structures of the two second vertical plates 122 are set the same as an example for description.

[0049] In view of this, a limiting groove 150 is locally recessed at the bottom end of the top seat 130 and / or the top end of the base 110; two second slots 122a are spaced apart at the position corresponding to the limiting groove 150 on the second vertical plate 122. The second slots 122a are generally long and narrow in the vertical direction, so as to be able to roughly divide the entire second vertical plate 122 into a part located between the two second slots 122a and two parts located outside the two second slots 122a. Among them, the part of the second vertical plate 122 between the two second slots 122a is folded towards the receiving cavity to form a second flanging 122b, and the second flanging 122b is inserted into the limiting groove 150. The folding dimension of the second flanging 122b is adapted to the corresponding limiting groove 150. Through the insertion connection between the second flanging 122b and the limiting groove 150, it helps to position and limit the insertion between the top seat 130 and the support base 120 and / or the insertion between the base 110 and the support base 120 in the longitudinal and transverse directions; and since the second flanging 122b has a certain elastic deformation ability, it then helps to achieve elastic support between the top seat 130 and the support base 120 and / or elastic support between the base 110 and the support base 120.

[0050] During actual application, taking the assembly between the top seat 130 and the support base 120 as an example, at least one limiting groove 150 can be opened on each of the lateral two sides of the top seat 130; the second flanging 122b is adapted to be arranged in one-to-one correspondence with the positions and dimensions of the respective limiting grooves 150.

[0051] In the above description, the second vertical plate 122 forms a connection portion 122c at a position other than the two second slots 122a, and the inner cavity wall at the connection portion 122c makes surface contact with the outer side wall of the corresponding top seat 130, and / or the inner cavity wall at the connection portion 122c makes surface contact with the outer side wall of the corresponding base 110, so that the support seat 120 and the top seat 130, and / or the support seat 120 and the base 110 can be detachably connected and fixed in the surface contact area through a detachable connection structure. The detachable connection method can be, but is not limited to, one or more of the following methods: screw fixation, snap fixation, magnetic fixation, adhesive fixation, and vacuum adsorption fixation.

[0052] It can be understood that when the housing assembly 100 is applied to the weighing module, it can be integrated with other components in the weighing module. When the weighing module is used in the beverage preparation equipment, the weighing module needs to be continuously or periodically fixed in a certain installation area in the beverage preparation equipment, and fixedly connected or movably connected with, for example, a carrier to be loaded. Therefore, in one embodiment, one longitudinal side of the base 110 is concave to form a slot 111, and the slot 111 is used for the insertion and connection of the plug-in protrusion of the body to be loaded. The other longitudinal side of the base 110 is partially concave in the slot 111 to form an avoidance groove 112, and the avoidance groove 112 and the slot 111 are not directly connected. The base 110 forms a barrier structure between the avoidance groove 112 and the slot 111. The barrier structure is provided with a threaded hole 113 along the longitudinal direction, and the threaded hole 113 connects the slot 111 and the avoidance groove 112. The housing assembly 100 further includes a screw connector 140, which is threadedly connected to the threaded hole 113 and extends into the slot 111 to connect and fix the plug-in protrusion, thereby fixing the plug-in protrusion to the base 110. That is, the weighing module is fixedly connected to the carrier to be installed.

[0053] Next, the first vertical plate 121 is provided with two first slots 121a at intervals corresponding to the avoidance groove 112. The first slots 121a also extend vertically in a narrow and long shape. The first vertical plate 121 is folded toward the receiving cavity at the portion between the two first slots 121a to form a first flange 121b. The first flange 121b extends into the avoidance groove 112 and presses the screw connection 140. In this way, when the screw connection 140 is connected to the threaded hole 113, the first flange 121b just presses against the end of the screw connection 140 that is opposite to the threaded hole 113 to prevent the screw connection 140 from falling out.

[0054] Further, the first flanging 121b extends obliquely relative to the first vertical plate 121. In this way, the first flanging 121b has a certain elastic deformation ability relative to the first vertical plate 121, that is, during the process of inserting the screwing member 140 into the avoidance groove 112 and screwing it with the threaded hole 113, the first flanging 121b can be turned over to form an avoidance; and then when the screwing member 140 is connected to the threaded hole 113 in place, the first flanging 121b can be reset and elastically press against the screwing member 140.

[0055] In addition, the base 110 is convexly provided with a reinforcing rib 114 in the avoidance groove 112. The reinforcing rib 114 is at least arranged on one side of the threaded hole 113 and is connected to at least three side walls of the avoidance groove 112. On the one hand, the reinforcing rib 114 is equivalent to a reinforcing structure of the avoidance groove 112 and can structurally support at least three side wall directions of the avoidance groove 112; on the other hand, it can laterally stop and structurally support the screwing member 140.

[0056] In view of the above, the present utility model also provides a weighing module, which includes the above-mentioned housing assembly 100, mounting seat 200, receiving container 300, driving device 400 and weighing device 500. Among them, the mounting seat 200 is suspended above the top seat 130; the receiving container 300 includes a container body 310 fixedly installed on the mounting seat 200 and an opening and closing member 320 movably installed on the mounting seat 200. The container body 310 is provided with a receiving channel 311 through it, and the opening and closing member 320 can open and close the receiving channel 311 during the moving process; the driving device 400 includes a driver 410 housed in the receiving cavity and a transmission component 420 at least partially exposed outside the receiving cavity. The transmission component 420 is connected to the driver 410 and the opening and closing member 320 to drive the opening and closing member 320 to move under the drive of the driver 410; the weighing device 500 includes a weighing part 510 fixedly connected to the mounting seat 200.

[0057] Of course, the present utility model also provides a beverage cooking device, which includes a grinding module and the above-mentioned weighing module. The weighing module is used to weigh the powder obtained by grinding the grinding module.

[0058] The specific type of the beverage cooking device is not limited in this design. The beverage cooking device can be a coffee grinder, mainly achieving the purpose of grinding bean materials into powder through the grinding module. At this time, the weighing module is arranged downstream of the grinding module. Or, the beverage cooking device can be a fully automatic coffee machine, which also includes a brewing module in addition to the grinding module. At this time, the weighing module is arranged between the downstream of the grinding module and the upstream of the brewing module. The beverage cooking device also includes a casing for housing various functional modules.

[0059] The grinding module may be but is not limited to including a grinding cylinder and a grinding mechanism. A grinding chamber is formed inside the grinding cylinder; the grinding mechanism includes, for example, two cutter disks that can be relatively movably arranged and a first driving device 400 that drives at least one cutter disk to move. A grinding gap for performing grinding and crushing operations such as puncturing, grinding, and stirring on granular materials such as coffee beans is formed between the two cutter disks. The grinding gap is set to be adjustable or set to be fixed. The downstream of the grinding module, that is, the outlet end corresponding to the grinding cylinder, can discharge the powder obtained by grinding outward.

[0060] The grinding module can directly access coffee beans from outside the machine housing. Or in an application, the machine body further includes a bean bin provided inside the machine housing. The bean bin is a container assembly that can provide a certain space to accommodate coffee beans. In actual use, the bean bin can be set to one or several according to actual needs. When several bean bins are set, each bean bin can be used to store the same coffee beans or different types of coffee beans.

[0061] The brewing module may be but is not limited to including a brewing cylinder and a brewing mechanism. The upstream of the brewing module, that is, the inlet end of the brewing cylinder. The brewing cylinder can access the required amount of coffee powder discharged outward through the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain coffee beverages.

[0062] According to different brewing requirements, the brewing mechanism is mainly set as a powder pressing module, a water supply component, etc. The brewing cylinder is provided with a brewing space for accommodating coffee powder. The powder pressing module includes two piston parts that can move relatively along the inner wall of the brewing cylinder inside the brewing cylinder. The two piston parts can move relatively closer or relatively farther away. A specific implementation manner includes: a lower piston part that can move up and down is provided inside the brewing cylinder, and an upper piston part that can move up and down is provided outside the brewing cylinder. The powder pressing module drives the upper piston part to move up and down. Among them, the upper piston and / or the lower piston can be set to move into the brewing cylinder or move out of the brewing cylinder relative to the brewing cylinder to open one end of the brewing cylinder, and the coffee powder enters the brewing cylinder or is discharged from the brewing cylinder through the opened end.

[0063] In one embodiment, the weighing module is arranged between the outlet end of the grinding module and the inlet end of the brewing module. The inlet end of the weighing module is connected to the outlet end of the grinding module in a switchable manner, and the outlet end of the weighing module is connected to the inlet end of the brewing module in a switchable manner. Among them, the weighing module can be fixedly installed inside the machine housing or detachably installed inside the machine housing. The weighing module, the grinding module, and the brewing module can be relatively fixed or relatively movable. When the weighing module moves close to the grinding module manually by the user or automatically driven by a preset power module:

[0064] If the inlet end of the weighing module is connected to the outlet end of the grinding module, and when the outlet end of the weighing module is closed or disconnected from the inlet end of the brewing module, the weighing module can receive and hold the coffee powder discharged from the outlet end of the grinding module, and perform the weighing function in real time or with a delay after the preset grinding duration ends. At this time, the weighing module is in the weighing mode. Of course, the weighing module can also receive and hold the coffee powder discharged from the outlet end of the grinding module, but does not perform the weighing function. At this time, the weighing module is in the pre-receiving mode without weighing.

[0065] If the inlet end of the weighing module is connected to the outlet end of the grinding module, and the outlet end of the weighing module is connected to the inlet end of the brewing module, the weighing module is set in a normally open form, so that when the powder material is conveyed from the grinding module to the brewing module, the powder material passes through the weighing module freely and unobstructed. The weighing module mainly functions to transition the powder material and does not perform the weighing function. At this time, the weighing module is in the non-weighing transition mode.

[0066] In view of the above, in the weighing module, the receiving channel 311 is connected to the outlet end of the grinding module and the inlet end of the brewing module. The opening and closing member 320 is movably arranged relative to the container body 310 to have an open position for conducting the receiving channel 311 and a closed position for truncating the receiving channel 311; the driving device 400 is drivingly connected to the opening and closing member 320. The weighing device 500 includes weighing parts 510 at both ends and a fixing part. The weighing parts 510 are fixedly connected to the receiving container 300, and the fixing part is fixedly connected to the driving device 400.

[0067] Among them, the container body 310 is generally cylindrical, and the inner space of the cylinder directly defines the receiving channel 311. The extending direction of the receiving channel 311 can be set according to actual needs, such as along the vertical direction or along a direction inclined relative to the vertical direction. Of course, the receiving channel 311 can be set as a straight channel structure, or can be set as a channel structure that is at least partially curved according to actual needs.

[0068] The opening and closing member 320 performs a translational movement relative to the container body 310. Specifically, the opening and closing member 320 is offset to one side of the outlet end of the receiving channel 311, and can be translated to the closed position on the other side of the outlet end of the receiving channel 311 and to the open position on the other side away from the outlet end of the receiving channel 311.

[0069] Since the weighing device 500 is generally in the shape of a cantilever extending horizontally or vertically, with its weighing part 510 and fixed part located at both ends in the horizontal or vertical direction. Therefore, in practical applications, the weighing part 510 is connected to the receiving container 300, and the receiving container 300, at least the part connected to the weighing part 510 (such as the mounting seat 200), can be suspended vertically below the weighing part 510 or supported vertically above the weighing part 510. Similarly, the fixed part is connected to the driving device 400, and the part of the driving device 400 that can be connected to the fixed part can be connected vertically below the fixed part or vertically above the fixed part.
