Description

Technical Field

[0001] This application relates to the field of ice food processor technology, and more particularly to an evaporator and an ice food processor. Background Technology

[0002] Ice food processors, also known as ice cream makers, are characterized by a main operating space consisting of a cooling plate. The working surface of the cooling plate is generally below 0°C. Users pour liquids such as water or milk onto the cooling plate and stir it. After a certain period of cooling, the desired shaved ice, ice cream, or other food products are formed.

[0003] Ice food processors typically require a refrigeration system connected to an evaporator as the cooling plate for cooling. During normal operation, a low-temperature, low-pressure gas-liquid mixture of cooling medium flows through its pipes.

[0004] Existing evaporators are designed with a single inlet and a single outlet, meaning there is an inlet for the cooling medium to enter and an outlet for the cooling medium to exit. These single-inlet, single-outlet evaporators can be configured in a serpentine shape. Typically, the inlet or outlet of a single-inlet, single-outlet serpentine evaporator is located around the periphery of the cooling plate. The temperature is higher in the center of the cooling plate and lower around the periphery. However, consumers are accustomed to pouring liquid food into the center of the cooling plate, resulting in low cooling efficiency and not conforming to consumer habits.

[0005] One-in-one-out evaporators can also be configured in a loop shape. The loop evaporator has a relatively complex tube winding process, and the pipes required to achieve the same cooling area as the serpentine evaporator are longer. It also has the problem that the temperature in the middle of the cooling plate is higher and the temperature on the periphery of the cooling plate is lower. Utility Model Content

The first straight section, the first curved section, and the second straight section are configured to fit against the refrigeration plate. The direction from the first straight section to the second straight section is a first direction, and the direction from the first straight section to the second straight section is a second direction, with the first direction and the second direction being opposite.

[0012] In one alternative, there are multiple first straight sections and multiple first curved sections. The multiple first straight sections are arranged at intervals along a direction away from the first pipe, and any two adjacent first straight sections are connected by the first curved sections.

[0040] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0042] To facilitate the reader's understanding of the design concept of this application, a brief description of the evaporator 10p in the prior art is provided below. The evaporator 10p in the prior art may be as follows: Figure 1 The snake shape shown, or as... Figure 2 As shown, whether serpentine or loop-shaped, both types of evaporators 10p have only one inlet 11p for the cooling medium to enter and one outlet 12p for the cooling medium to exit, forming a one-in-one-out configuration. Generally, in a one-in-one-out serpentine evaporator (or loop-shaped evaporator), the inlet 11p or outlet 12p is located around the periphery of the cooling plate. The temperature is higher in the center of the cooling plate and lower around the periphery. However, consumers are accustomed to pouring liquid food into the center of the cooling plate, resulting in low cooling efficiency and being unsuitable for consumer habits. Furthermore, in actual use, food near the inlet 11p of the evaporator 10p may have solidified, while food near the outlet 12p of the evaporator 10p may still be in a solid-liquid mixture. In other words, the one-in-one-out evaporator 10p suffers from uneven temperature distribution.

[0043] Please see Figure 3 and Figure 4This application provides an evaporator 10, including a first pipe 1 with a first inlet 1a and a first outlet 1b, and a second pipe 2 with a second inlet 2a and a second outlet 2b. Both the first inlet 1a and the second inlet 2a are positioned near the center of the cooling plate 5. The first pipe 1 and the second pipe 2 are arranged with bends in opposite directions and are both positioned on the cooling plate 5. Through this evaporator 10, both the first inlet 1a and the second inlet 2a are used for the entry of cooling medium, and both the first outlet 1b and the second outlet 2b are used for the exit of cooling medium, forming a two-inlet, two-outlet configuration. The working surface of the cooling plate 5 has a lower temperature in the area near the first inlet 1a and the second inlet 2a, resulting in a lower temperature in the center of the cooling plate 5, which is suitable for consumer usage habits and improves cooling efficiency. Specifically, the applicant of this application has found that when consumers actually use the product, they tend to pour liquid food into the cooling plate 5 first, and then spread it to the sides. In this embodiment, the first inlet 1a and the second inlet 2a of the evaporator 10 are located near the center of the cooling plate 5. The cooling medium flows in from the first inlet 1a and the second inlet 2a and flows to both sides along the first pipe 1 and the second pipe 2, and flows out from the evaporator 10. This results in a lower temperature in the center of the cooling plate 5 and a higher temperature on the periphery of the cooling plate 5. Through this flow path design, the flow direction of liquid food is basically consistent with the flow direction of the cooling medium, which adapts to the user's habits, improves the cooling efficiency, and ensures the consistency of the freezing time of food after it is spread on the working surface of the cooling plate 5.

[0044] Furthermore, compared to the single-inlet-single-outlet configuration in the prior art, cooling efficiency can be improved. Additionally, because the first pipe 1 and the second pipe 2 are arranged with bends in opposite directions, the working surface of the refrigeration plate 5 has a lower temperature near the first inlet 1a and the second inlet 2a, thus forming two low-temperature regions, and a higher temperature near the first outlet 1b and the second outlet 2b, thus forming two high-temperature regions. Compared to the single-inlet-single-outlet configuration in the prior art (which only forms one low-temperature region and one high-temperature region), the evaporator 10 of this application balances the temperature through two low-temperature regions and two high-temperature regions, alleviating the problem of uneven temperature distribution.

[0045] It is worth noting that in some embodiments, the first pipe 1 is made of copper, and the second pipe 2 is made of copper.

[0046] The middle position of the cooling plate 5 refers to a certain area near the center of the cooling plate 5 along its length (equivalent to the first direction D1 or the second direction D2 in the following text).

[0047] The first pipe 1 includes a first section 11, a first straight section 12, a first curved section 13, a second straight section 14, and a second section 15 connected in sequence. The first inlet 1a is located at the end of the first section 11 away from the first straight section 12, and the first outlet 1b is located at the end of the second section 15 away from the second straight section 14. The first straight section 12, the first curved section 13, and the second straight section 14 are used to fit the refrigeration plate 5. The cooling medium enters from the first inlet 1a, flows through the first section 11, the first straight section 12, the first curved section 13, the second straight section 14, and the second section 15, and then flows out from the first outlet 1b to cool the food on the refrigeration plate 5 fitted to the first pipe 1.

[0048] In some embodiments, there are multiple first straight sections 12 and multiple first curved sections 13. The multiple first straight sections 12 are arranged sequentially at intervals along a direction away from the second pipe 2, and any two adjacent first straight sections 12 are connected by a first curved section 13. This arrangement increases the contact area between the first pipe 1 and the cooling plate 5, thereby improving the cooling effect.

[0049] It is understandable that, since both the first inlet 1a and the second inlet 2a are set near the middle of the cooling plate 5, the multiple first straight sections 12 are actually arranged along the middle of the cooling plate 5 towards one end of the cooling plate 5.

[0050] In some embodiments, the direction from the first straight segment 12 to the second straight segment 14 is the first direction D1, the second direction D2 is opposite to the first direction D1, the third direction D3 is perpendicular to the first direction D1, and the third direction D3 is used to be perpendicular to the working plane 51 of the refrigeration plate 5. The working plane 51 of the refrigeration plate 5 is the plane on which the refrigeration plate 5 is used to refrigerate food. The fourth direction D4 is perpendicular to both the first direction D1 and the third direction D3. The second segment 15 includes a first curved portion 151 and a first portion 152 connected in sequence. The first curved portion 151 is connected to the first straight segment 14. The second straight section 14 has a first curved portion 151 that bends from the second straight section 14 toward the direction of the first straight section 12. Both the first curved portion 151 and the first portion 152 are designed to fit the cooling plate 5. The first portion 152 bends and extends toward a third direction D3 to form a second portion 153. The second portion 153 bends and extends toward a fourth direction D4 to form a third portion 154. The third portion 154 bends and extends toward a second direction D2 to form a fourth portion 155. The first outlet 1b is located at the end of the fourth portion 155 away from the third portion 154. With this arrangement, the first outlet 1b can be positioned close to the center of the cooling plate 5, and the first outlet 1b and the first inlet 1a are positioned close to the same location.

[0051] In some embodiments, the first segment 11 is bent toward the third direction D3, the first segment 11 is away from the working plane 51 of the refrigeration plate 5, and the first segment 11 is the location of the first inlet 1a. With this arrangement, it is at least convenient for the first pipe 1 to be assembled with external equipment through the first segment 11.

[0052] It is understood that the design of the first pipe 1 is not limited to the form shown in the accompanying drawings of this application.

[0053] The second pipe 2 described above can have the same structure as the first pipe 1. The second pipe 2 includes a first section 21, a first straight section 22, a first curved section 23, a second straight section 24, and a second section 25 connected in sequence. The second inlet 2a is located at the end of the first section 21 away from the first straight section 22, and the second outlet 2b is located at the end of the second section 25 away from the second straight section 24. The first straight section 22, the first curved section 23, and the second straight section 24 are used to fit the refrigeration plate 5. The cooling medium enters from the second inlet 2a, flows through the first section 21, the first straight section 22, the first curved section 23, the second straight section 24, and the second section 25, and then flows out from the second outlet 2b to cool the food on the refrigeration plate 5 fitted to the second pipe 2. In addition, the direction from the first straight section 12 to the second straight section 14 is the first direction D1, and the direction from the first straight section 22 to the second straight section 24 is the second direction D2. The first direction D1 and the second direction D2 are opposite, forming a shape in which the first pipe 1 and the second pipe 2 bend in opposite directions.

[0054] In some embodiments, there are multiple first straight sections 22 and multiple first curved sections 23. The multiple first straight sections 22 are arranged sequentially at intervals along a direction away from the first pipe 1, and any two adjacent first straight sections 22 are connected by a first curved section 23. This arrangement increases the contact area between the second pipe 2 and the cooling plate 5, thereby improving the cooling effect.

[0055] It is understandable that, since both the first inlet 1a and the second inlet 2a are used to be set in the middle near the refrigeration plate 5, the multiple first straight sections 22 are actually arranged along the middle of the refrigeration plate 5 toward the end of the refrigeration plate 5 away from the first pipe 1.

[0056] In some embodiments, the second section 25 includes a first curved region 251 and a first region 252 connected in sequence. The first curved region 251 is connected to the second straight section 24. The first curved region 251 bends from the second straight section 24 toward the direction of the first straight section 22. Both the first curved region 251 and the first region 252 are configured to conform to the cooling plate 5. The first region 252 bends and extends toward a third direction D3 to form a second region 253. The second region 253 bends and extends toward a fourth direction D4 to form a third region 254. The third region 254 bends and extends toward a first direction D1 to form a fourth region 255. The second outlet 2b is located at the end of the fourth region 255 away from the third region 254. With this configuration, the second outlet 2b can be positioned close to the center of the cooling plate 5, and the second outlet 2b and the second inlet 2a are positioned close to the same location.

[0057] In some embodiments, the first section 21 is bent toward the third direction D3, and the first section 21 is away from the working plane 51 of the refrigeration plate 5. The first section 21 is the location of the second inlet 2a. With this arrangement, it is at least convenient for the second pipe 2 to be assembled with external equipment through the first section 21.

[0058] It is understood that the design of the second pipe 2 is not limited to the form shown in the attached drawings of this application.

[0059] It is worth noting that in some embodiments, not only are the first inlet 1a and the second inlet 2a both positioned near the center of the cooling plate 5, but the first outlet 1b and the second outlet 2b are also positioned near the center of the cooling plate 5. The first inlet 1a and the first outlet 1b are located near the same position, and the second inlet 2a and the second outlet 2b are also located near the same position. This means that after the first pipe 1 is bent, the first outlet 1b returns to the vicinity of the first inlet 1a, and after the second pipe 2 is bent, the second outlet 2b returns to the vicinity of the second inlet 2a. Actual testing has verified that the evaporator 10 with this layout has a temperature difference of less than 3°C on the working surface of the cooling plate 5. Furthermore, the first pipe 1 is symmetrically arranged relative to the second pipe 2. The symmetrical arrangement of the first pipe 1 and the second pipe 2 results in the same cooling effect on the cooling plate 5, improving the uniformity of the temperature distribution in the evaporator 10.

[0060] Please see Figure 5The working principle of the evaporator 10 provided in this application embodiment is as follows: the cooling medium flows in from the first inlet 1a of the first pipe 1, passes through the first curved portion 151, the first portion 152, the second portion 153, the third portion 154 and the fourth portion 155 in the first section 11, the first straight section 12, the first curved section 13, the second straight section 14 and the second section 15, and flows out from the first outlet 1b; in addition, the cooling medium also flows in from the second inlet 2a of the second pipe 2, passes through the first curved region 251, the first region 252, the second region 253, the third region 254 and the fourth region 255 in the first section 21, the first straight section 22, the first curved section 23, the second straight section 24 and the second section 25, and flows out from the second outlet 2b.

[0061] According to one aspect of the embodiments of this application, please refer to Figure 6 A food processor 20 is provided, comprising a housing 3, a refrigeration system 4, an electronic control system (not shown), a refrigeration plate 5, and an evaporator 10 disposed in the housing 3; the electronic control system is connected to the refrigeration system 4, and the evaporator 10 is connected to both the refrigeration plate 5 and the refrigeration system 4; the refrigeration system 4 supplies a cooling medium to the evaporator 10. For the specific structure and function of the evaporator 10, please refer to the foregoing description, which will not be repeated here.

[0062] The evaporator 10 can be connected to the refrigeration plate 5 by welding or gluing.

[0063] The housing 3 includes a first housing 31 and a bottom plate 32 disposed opposite to each other, a second housing 33 and a third housing 34 disposed opposite to each other on both sides of the first housing 31, and a fourth housing 35 and a fifth housing 36 disposed opposite to each other on the other two sides of the first housing 31. The second housing 33, the fourth housing 35, the third housing 34 and the fifth housing 36 are connected in sequence.

[0064] Please refer to Figure 6 and Figure 7 The refrigeration system 4 includes a compressor 41, a condenser 42, a throttling device 43, a solenoid valve 44, and a connecting pipe 45. The output end of the compressor 41 is connected to the input end of the condenser 42. The output end of the condenser 42 is connected to one end of the throttling device 43. The other end of the throttling device 43 is connected to the input end of the evaporator 10 through the connecting pipe 45 and the solenoid valve 44. The output end of the evaporator 10 is connected to the input end of the compressor 41.

[0065] When the refrigeration system 4 is working, the compressor 41 performs work, transferring the high-temperature and high-pressure gaseous cooling medium to the condenser 42. Due to the large heat exchange area of ​​the condenser 42, the high-temperature and high-pressure gaseous cooling medium becomes a medium-temperature and high-pressure liquid cooling medium after heat exchange inside it and flows out. After being depressurized by the throttling device 43, it becomes a low-temperature and low-pressure gas-liquid mixture and enters the evaporator 10. At this time, because the refrigeration plate 5 is in close contact with the evaporator 10, heat exchange occurs between the two, causing the surface temperature of the refrigeration plate 5 to drop rapidly.

[0066] The throttling device 43 can be a capillary tube.

[0067] In some embodiments, the refrigeration system 4 further includes an air supply component 46, which is disposed adjacent to the condenser 42 and is used to dissipate heat from the condenser 42. In this embodiment, the air supply component 46 is a fan.

[0068] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application.
