Description

Technical Field

[0001] This application relates to the field of ice-making equipment technology, and in particular to a smoothie machine. Background Technology

[0002] A smoothie machine is a device used to make smoothies. Smoothie machines in related technologies often use different liquids to be frozen (such as sugar water, ice cream base, purified water, etc.) to make smoothies. Specifically, in the initial stage of ice making, the controller adjusts the rotation speed of the evaporator drum based on the type of liquid to be frozen collected by the signal collector. During ice making, the evaporator drum maintains constant rotation speed and keeps in contact with the liquid to be frozen, absorbing heat from the liquid and causing the liquid adhering to the outer circumference of the evaporator drum to freeze quickly. A scraper cuts the ice layer on the evaporator drum to obtain a smooth smoothie.

[0003] However, since smoothie makers are small household appliances, adjusting the rotation speed of the evaporator drum requires additional speed control components such as frequency converters, as well as corresponding control algorithms, which increases product costs and affects product competitiveness. Utility Model Content

[0004] The purpose of this application is to provide a smoothie machine to solve the above-mentioned problems.

[0005] According to some aspects of this application, a smoothie machine is provided, comprising: chassis; A tray used to hold liquids that are to be frozen; The evaporator drum is rotatable about its own axis relative to the housing; a portion of the evaporator drum is housed within the tray. A scraper is fixed to the housing, and an ice-scraping gap is formed between the scraper and the outer peripheral surface of the evaporator drum. A liquid storage tank is movably connected to the tray; the liquid storage tank has an opening, and the interior of the liquid storage tank communicates with the interior of the tray through the opening; the liquid storage tank has a first position and a second position, when the liquid storage tank is in the first position, the liquid level of the liquid to be frozen in the tray is at the first liquid level; when the liquid storage tank is in the second position, the liquid level of the liquid to be frozen in the tray is at the second liquid level; the second liquid level is higher than the first liquid level.

[0006] In some embodiments, the liquid storage tank has an indicator end that is exposed on the outer surface of the liquid storage tank; the housing is provided with two different indicator portions that are spaced apart on the outer surface of the housing. When the liquid level of the liquid to be frozen in the tray is at the first liquid level, the indicator terminal indicates one of the indicator parts; when the liquid level of the liquid to be frozen in the tray is at the second liquid level, the indicator terminal indicates the other indicator part.

[0007] In some embodiments, the liquid storage tank can rotate relative to the housing about its own axis so that the plane containing the opening is away from or close to the tray, wherein the rotation axis of the liquid storage tank is perpendicular to the rotation axis of the evaporator drum.

[0008] In some embodiments, the housing has a first cavity; the housing includes a top shell, the top shell having a notch communicating with the first cavity; The liquid storage tank includes a first tank and a second tank; the first tank is rotatable relative to the top shell and exposed outside the housing; the second tank is connected to the first tank, the opening is located in the second tank, and the portion of the second tank containing the opening extends into the first cavity and is rotatably connected to the tray.

[0009] In some embodiments, the outer surface of the top shell has at least two grooves, which are spaced apart and surround the notch; the liquid storage tank has protrusions in the same number and corresponding positions as the grooves. When the liquid storage tank is rotated by an external force until each of the protrusions is embedded in the corresponding groove, the first tank body abuts against the outer surface of the top shell, and the liquid storage tank is in the first position; when the liquid storage tank is rotated by an external force until each of the protrusions abuts against the outer surface of the top shell, the liquid storage tank is in the second position.

[0010] In some embodiments, the housing has a second cavity communicating with the first cavity, and the second cavity and the first cavity are arranged sequentially in a direction opposite to the direction of gravity; The tray is inclined relative to the horizontal plane and is divided into a lower part and a higher part. The lower part is suspended above the second cavity, and the higher part is located in the first cavity. The evaporator roller and the scraper are both suspended above the second chamber; a portion of the evaporator roller is housed in the lower portion; the second housing extends through the notch into the first chamber and is rotatably connected to the higher portion.

[0011] In some embodiments, the smoothie machine includes a spring return valve located at the opening; The bottom wall of the tray has a protruding part, which is located in the higher part. The protruding part extends into the valve core of the spring reset valve and abuts against the push rod of the spring reset valve. At the same time, the liquid storage tank and the spring reset valve can rotate relative to the protruding part, and the liquid storage tank is connected to the inside of the tray.

[0012] In some embodiments, the first housing and the second housing are two independent components; the first housing and the second housing are connected by a threaded seal.

[0013] In some embodiments, the bottom of the first housing has a first annular peripheral wall, and the outer surface of the first annular peripheral wall is provided with external threads; the top of the second housing has a second annular peripheral wall, and the inner surface of the second annular peripheral wall is provided with internal threads, the internal threads engaging with the external threads, so that the second annular peripheral wall is sleeved on the outside of the first annular peripheral wall.

[0014] The beneficial effects of this application embodiment are: without changing the rotation speed of the evaporator drum, the user can adjust the distance between the liquid storage tank and the tray according to the different adaptability of the liquid to be frozen, so that the evaporator drum is submerged below the appropriate liquid level of the liquid to be frozen. When making ice, different liquids to be frozen have a good contact area with the evaporator drum, which saves product costs and also avoids the situation that the ice layer formed on the evaporator drum by different liquids to be frozen is prone to breakage, peeling or incomplete formation.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] In the description of this application, it should be noted that the use of terms such as "first" and "second" to define the components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0021] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see also Figures 1 to 8 One embodiment of this application provides a smoothie machine, which includes a housing 10, an ice-making component, a tray 30, a scraper 40, and a liquid storage tank 50.

[0023] The housing 10 serves not only as the mounting base for the aforementioned components but also as the support structure for the tray 30.

[0024] Tray 30 is used to hold liquids to be frozen.

[0025] The ice-making assembly includes an evaporator roller 21. The evaporator roller 21 is located outside the housing 10 and rotates relative to the housing 10 about its own axis 21A. A portion of the evaporator roller 21 is housed in a tray 30.

[0026] The ice-making assembly also includes a power source (not shown) and a transmission mechanism (not shown). Both the power source and the transmission mechanism are fixedly connected within the housing 10. The power source drives the evaporator drum 21, which is inserted into the shaft within the housing 10, via the transmission mechanism, causing the evaporator to rotate around its own axis 21A. For example, the power source can be a DC motor, and the transmission mechanism can be a reduction gearbox, thereby adjusting the evaporator drum 21 to a fixed speed to meet the actual usage requirements of the smoothie machine.

[0027] In addition, the ice-making assembly also includes a compressor 24 and a condenser 25. Both the compressor 24 and the condenser 25 are fixedly connected inside the housing 10. Refrigerant circulates between the compressor 24, the condenser 25, and the evaporator drum 21. After the refrigerant is input from the compressor 24 to the condenser 25, the refrigerant output from the condenser 25 enters the evaporator drum 21, and the refrigerant output from the evaporator returns to the compressor 24, and so on.

[0028] The scraper 40 is located outside the housing 10 and fixed to the housing 10. A scraping gap (not shown in the figure) is formed between the scraper 40 and the evaporator drum 21. The size of the scraping gap needs to be set by taking into account various factors such as the material and hardness of the scraper 40, the rotation speed and temperature of the evaporator drum 21, and the working conditions and design requirements of the smoothie machine. No specific limit is given here.

[0029] The liquid storage tank 50 is detachably connected to the tray 30. The liquid storage tank 50 has an opening 502a, through which it communicates with the interior of the tray 30. The liquid storage tank 50 has a first position and a second position. When the liquid storage tank 50 is in the first position, the liquid level of the liquid to be frozen in the tray 30 is at the first liquid level; when the liquid storage tank 50 is in the second position, the liquid level of the liquid to be frozen in the tray 30 is at the second liquid level. The second liquid level is higher than the first liquid level.

[0030] The liquid storage tank 50 is configured to move the plane of the opening 502a away from the tray 30 when driven by an external force, so that the liquid level of the liquid to be frozen in the tray 30 rises from the first liquid level to the second liquid level.

[0031] To help readers understand the technical solution of the smoothie machine provided in this application, the following example illustrates the operation process of the smoothie machine.

[0032] Before ice making, the relative positions of the storage tank 50 and the tray 30 are adjusted according to the freezing point of the liquid to be frozen. Specifically, when the liquid to be frozen is a liquid with a freezing point of 0°C, such as low-concentration sugar water or purified water, the relative positions of the storage tank 50 and the tray 30 do not need to be adjusted. At this time, the storage tank 50 is in the first position, and the liquid level of the liquid to be frozen in the tray 30 is at the initial liquid level (i.e., the first liquid level), and the contact area between the liquid to be frozen and the evaporator roller 21 is small. When the liquid to be frozen is a liquid with a freezing point below 0°C, such as high-concentration sugar water or ice cream liquid, the relative position of the storage tank 50 is adjusted to move away from the tray 30, and the storage tank 50 is raised to the second position, so that the liquid level of the liquid to be frozen in the tray 30 rises from the initial liquid level to the set liquid level (the second liquid level), and the contact area between the liquid to be frozen and the evaporator roller 21 is larger.

[0033] Subsequently, the liquid to be frozen stored in the storage tank 50 continuously flows into the tray 30 through the opening 502a until the opening 502a is submerged below the surface of the liquid to be frozen. The storage tank 50 cannot directly exchange gas with the outside world, and the liquid level of the liquid to be frozen in the tray 30 remains constant during ice making.

[0034] During ice making, the evaporator drum 21 rotates around its own axis 21A. The liquid to be frozen adheres to the outer circumferential surface of the evaporator drum 21 and exchanges heat with the refrigerant inside the evaporator drum 21, causing the liquid to release heat and its temperature to drop until the temperature of the liquid to be frozen drops below the freezing point, forming an ice layer on the outer circumferential surface of the evaporator drum 21. After the thickness of the ice layer exceeds the ice scraping gap, the scraper 40 cuts the ice layer on the evaporator drum 21 to obtain soft ice shavings.

[0035] After ice making is complete, manually adjust the liquid storage tank 50 to move it closer to the tray 30 to complete the reset; or, keep the liquid storage tank 50 in a position away from the tray 30.

[0036] For casing 10, please refer to Figure 4 See also Figures 1 to 3 In some embodiments, as shown in any of the accompanying drawings, the housing 10 has a first cavity 10a and a second cavity 10b arranged sequentially along the direction of gravity, and the first cavity 10a and the second cavity 10b are interconnected. The aforementioned tray 30 is housed in the first cavity 10a, and the aforementioned evaporator roller 21 and scraper 40 are both located in the first cavity 10a. The second cavity 10b can accommodate a smoothie cup, facilitating the removal of the smoothie cut by the scraper 40. The housing 10 has a cavity in which some components of the aforementioned drive assembly, the power source, the transmission mechanism, the compressor 24, and the condenser 25 are all housed. Exemplarily, continuing as follows... Figure 4 As shown, the housing 10 is generally rectangular and includes a front shell 11, a back shell 12, two side shells 13, a bottom shell 14, and a top shell 15. The top shell 15 and the bottom shell 14 are positioned opposite each other and spaced apart along the direction of gravity. The two side shells 13 are positioned opposite each other and spaced apart. The front shell 11 and the rear shell are positioned opposite each other in the front-rear direction of the side shells 13, and together with the two side shells 13, the top shell 15, and the bottom shell 14, they enclose the aforementioned cavity. The surface of the front shell 11 near the top shell 15 is recessed towards the side where the rear shell is located to form the aforementioned first cavity 10a. The surface of the front shell 11 near the bottom shell 14 is recessed towards the side where the rear shell is located to form the aforementioned second cavity 10b.

[0037] In some embodiments, the housing 10 has a notch 15a communicating with the first cavity 10a, the notch 15a allowing the tray 30 to pass through, thereby keeping the tray 30 contained within the first cavity 10a. Exemplarily, continuing as... Figure 4 As shown, the aforementioned notch 15a is located at the top of the first cavity 10a and is opened in the middle of the side of the top shell 15 facing the front shell 11. The shape of part of the notch 15a is adapted to the liquid storage tank 50 so that the liquid storage tank 50 can pass through the notch 15a and extend into the first cavity 10a to be movably connected with the tray 30.

[0038] For pallet 30, please refer to Figure 8 See also Figure 6 and Figure 5 In some embodiments, the tray 30 is housed within the first cavity 10a and is limited by the housing 10 and the scraper 40. Exemplarily, the tray 30 includes a bottom wall 31, a rear side wall 32, and a surrounding edge 33. The rear side wall 32 is integrally formed on one edge of the bottom wall 31 near the cavity, and the surrounding edge is integrally formed on the periphery of the bottom wall 31 and the rear side wall 32. The bottom wall 31, the rear side wall 32, and the surrounding edge together form a liquid storage tank 30a with an open top. The bottom wall 31 is supported by the front shell 11, and the surrounding edge and the rear side wall 32 are respectively disposed opposite to and limited by the respective side walls of the front shell 11.

[0039] To improve the ice-making efficiency of the ice-making components, continue as follows Figure 6As shown, in some embodiments, the tray 30 is inclined relative to a horizontal plane and has a lower portion 301 and a higher portion 302, with a portion of the evaporator roller 21 housed in the lower portion 301. Exemplarily, continuing as... Figure 5 As shown, the bottom wall 31 extends downwards gradually from the end closest to the rear side wall 32, causing the tray 30 to tilt relative to the horizontal plane and dividing the tray 30 into a lower part 301 and a higher part 302. When the liquid to be frozen is injected into the storage tank 30a, the liquid can gather in the lower part 301 and make full contact with the evaporator drum 21. In the same freezing time, the evaporator drum 21 needs to freeze less liquid, the ice layer formed on the evaporator drum 21 freezes faster, and the ice-making efficiency of the ice-making component is also higher.

[0040] Please continue reading Figure 5 To further facilitate the handling of the tray 30, the front shell 11 includes an end wall 111, a first transition wall 112, a second transition wall 113, and a support wall 114, integrally formed sequentially along the direction of gravity. The end wall 111 is located at the top of the first cavity 10a. Both the end wall 111 and the first transition wall 112 are positioned opposite to the rear side wall 32 of the tray 30, with the end wall 111 being further away from the rear side wall 32 of the tray 30 than the first transition wall 112. The second transition wall 113 is shaped to correspond to the rear side wall 32 of the tray 30, and the second transition wall 113 and the scraper 40 together can confine the tray 30 within a certain displacement range. The shape of the support wall 114 corresponds to a portion of the bottom wall 31 of the tray 30, and the portion of the bottom wall 31 is supported by the support wall 114. When the tray 30 is housed in the first cavity 10a, an area for the user's palm is formed between the end wall 111 and the rear side wall 32. The user can reach into this area through the notch 15a to grasp or release the grip portion of the tray 30, thereby providing further convenience for taking and putting away the tray 30.

[0041] Further reading is available upon request. Figure 5 The lower portion 301 of the tray 30 is suspended above the second cavity 10b, while the higher portion 302 of the tray 30 is supported by the supporting wall 114. This arrangement provides clearance for the tray 30, allowing it to deflect at a certain angle within this clearance, making it easier for the user to place and remove the tray 30. Furthermore, the evaporator roller 21 and the scraper 40 are also suspended above the second cavity 10b, allowing the ice layer cut by the scraper 40 to fall into the second cavity 10b and be collected by the smoothie cup to obtain a smooth smoothie.

[0042] Furthermore, please continue to see Figure 5The front shell 11 also includes an inner eaves wall 116. The inner eaves wall 116 is located below the support wall 114 and is integrally formed with the support wall 114 through a smooth transition wall 115. The inner eaves wall is recessed from the second cavity 10b toward the inner cavity. When the user cleans the evaporator drum 21, the smooth transition wall 115 can guide the cleaning liquid. Due to the presence of the inner eaves wall 116, the liquid drips from the smooth transition wall 115 and has less contact with the end wall 111 below, making the cleaning of the evaporator drum 21 easier.

[0043] For the 50-liter reservoir, please refer to... Figure 7 and Figure 5 See also Figure 2 and Figure 3 In some embodiments, the liquid storage tank 50 includes a first housing 501 and a second housing 502. The first housing 501 and the second housing 502 are two independent components. The first housing 501 is supported by the top shell 15 and protrudes outside the housing 10. The second housing 502 is detachably connected to the first housing 501. The second housing 502 has the aforementioned opening 502a. The portion of the second housing 502 with the opening 502a extends through the notch 15a into the first cavity 10a and is detachably connected to the tray 30, so that the interior of the liquid storage tank 50 is connected to the liquid storage tank 30a. Compared to a one-piece molded liquid storage tank 50, the first housing 501 and the second housing 502 are connected by a threaded seal, which simplifies the manufacturing difficulty of the liquid storage tank 50 and thus reduces the cost of the smoothie machine.

[0044] For example, such as Figure 1As shown, the first housing 501 is generally disc-shaped, with a first annular peripheral wall 5012 formed at the center of its bottom. The outer surface of the first annular peripheral wall 5012 has external threads. The second housing 502 is generally funnel-shaped, with a second annular peripheral wall 5021 formed at the center of its top. The inner surface of the second annular peripheral wall 5021 has internal threads that mesh with the external threads, allowing the second annular peripheral wall 5021 to fit over the first annular peripheral wall 5012. An opening 502a is located at the end of the second housing 502 away from the first housing 501, and a spring return valve 60 is connected to the opening 502a via, but not limited to, a flexible rubber ring. The bottom wall 31 of the tray has a protruding part 311, which is located in the higher part 302. The protruding part 311 extends into the valve core of the spring return valve 60 and abuts against the push rod of the spring return valve 60, so that the liquid storage tank 50 is connected to the liquid storage tank 30a. With this configuration, changing the position of the liquid storage tank 50 relative to the top shell 15 will also change the position of the plane where the opening 502a is located relative to the tray 30, thereby matching the required contact area with the evaporator for different liquids to be frozen. Moreover, during the movement of the plane where the opening 502a is located, the protruding part 311 can continuously abut against the push rod of the spring return valve 60, so that the liquid storage tank 50 and the liquid storage tank 30a remain in communication, and the liquid to be frozen is stably supplied to the liquid storage tank.

[0045] Continue as Figure 2 and Figure 3 As shown, in some embodiments, the liquid storage tank 50 is rotatably connected to the housing 10 about its own axis 50A and rotatably connected to the tray 30, so that the plane containing the opening 502a is away from the tray 30. The rotation axis 50A of the liquid storage tank is perpendicular to the rotation axis 21A of the evaporator drum. It should be noted that any deviation of the included angle or right angle between the two rotation axes within 5° should be considered as the two rotation axes being perpendicular to each other. This deviation angle may be caused by manufacturing errors or other reasons.

[0046] For example, continue as follows Figure 2As shown, the outer surface of the top shell 15 has at least two grooves 15b, which are spaced apart and surround the notch 15a. The first housing 501 has protrusions 5011 in the same number and corresponding positions as the grooves 15b. The ejector part 311 extends into the valve core of the spring return valve 60 and abuts against the push rod of the spring return valve 60, allowing both the liquid storage tank 50 and the spring return valve 60 to rotate relative to the ejector part 311. At the same time, the liquid storage tank 50 is connected to the tray 30. In practice, the user can manually rotate the liquid storage tank 50. When the liquid storage tank 50 is rotated by external force until each protrusion 5011 is embedded in the corresponding groove 15b, the bottom surface of the first housing 501 abuts against the outer surface of the top shell 15, the liquid storage tank 50 is in the first position, and the liquid level of the liquid to be frozen in the tray 30 is at the first liquid level. When the liquid storage tank 50 is rotated by an external force until each protrusion 5011 abuts against the outer surface of the top shell 15, the liquid storage tank 50 is in the second position, the plane where the opening 502a is located is far away from the bottom wall 31 of the tray, and the liquid level of the liquid to be frozen in the liquid storage tank 30a rises from the first liquid level to the second liquid level.

[0047] It is understood that the various embodiments of this application do not specifically limit the adjustment method of the liquid storage tank 50, as long as the liquid storage tank 50 moves relative to the housing 10, allowing the liquid storage tank 50 to move from the first position to the second position, so that the plane where the opening 502a is located moves away from the tray 30 simultaneously, causing the liquid level of the frozen liquid in the tray 30 to rise from the first liquid level to the second liquid level. For example, in some other embodiments, a gasket of different thickness can be added between the bottom surface of the first housing 501 and the top surface of the top shell 15. The thickness of the gasket is equal to the increase in height of the plane where the opening 502a is located relative to the tray 30, which can also allow the liquid to be frozen in the tray 30 to rise from the first liquid level to the second liquid level.

[0048] Continue as Figure 2As shown, to facilitate intuitive observation of the location of the opening 502a on the plane, in some embodiments, the liquid storage tank 50 has an indicator end 5013, which is exposed on the outer surface of the liquid storage tank 50. The housing 10 is provided with two different indicator portions 151, which are spaced apart on the outer surface of the housing 10. For example, the indicator end 5013 is an indicator arrow, located at one end of the top surface of the first housing 501, and the two indicator portions 151 are spaced apart on the outer surface of the top housing 15, with the two indicator portions 151 being different letter identifiers. One indicator 151 corresponds to the location of any groove 15b, and the other indicator 151 is at a certain angle to the first indicator 151, which is smaller than the angle between two adjacent grooves 15b. Thus, when the liquid level of the liquid to be frozen in the tray 30 is at the first liquid level, the indicator end 5013 indicates one of the indicator parts 151; when the liquid level of the liquid to be frozen in the tray 30 is at the second liquid level, the indicator end 5013 indicates the other indicator part 151. Of course, the indicator end 5013 can also be any other indicator other than an indicator arrow, and the indicator part 151 can also be any other indicator other than a letter mark.

[0049] The smoothie machine involved in this application allows users to adjust the distance between the liquid storage tank 50 and the tray 30 according to the different adaptability of the liquid to be frozen, without changing the rotation speed of the evaporator drum 21. This ensures that the evaporator drum 21 is submerged below the appropriate liquid level of the liquid to be frozen. During ice making, different liquids to be frozen have a good contact area with the evaporator drum 21, which saves product costs and also avoids the situation where the ice layer formed on the evaporator drum 21 by different liquids to be frozen is prone to breakage, peeling, or incomplete formation.
