Description

Technical Field

[0001] This utility model belongs to the field of evaporator technology, and in particular relates to an evaporator structure for an ice cream machine. Background Technology

[0002] Ice cream machines are commonly used to mix and churn cream, milk powder, water, or other edible ingredients such as fruits in a specific ratio to create various flavors of ice cream. The evaporator is an important part of the refrigeration system inside the ice cream machine. It is usually connected to refrigeration equipment such as a compressor and is used to contact the beverage container to cool the beverage inside.

[0003] In existing ice cream production, the evaporator typically uses a copper tube winding structure. Existing patents, such as CN101749894A, disclose a hard ice cream machine evaporator with a condensing copper tube, which also discloses a special winding fixture and winding method for the condensing copper tube. The refrigerant flows inside the copper tube, separated from the beverage in the container by three layers of wall thickness: the container wall thickness, the copper tube wall thickness, and the evaporator barrel wall thickness. This results in low refrigeration and heat absorption efficiency, relatively high production costs, and longer ice cream forming time, affecting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide an evaporator structure for an ice cream machine, aiming to solve the technical problems of low cooling and heat absorption efficiency, relatively high manufacturing cost, and long ice cream forming time in existing ice cream machine evaporator structures.

[0005] To achieve the above objectives, this utility model provides an evaporator structure for an ice cream machine, including an outer tub and an inner tub fitted inside the outer tub. A cooling chamber is formed between the inner tub and the outer tub. Multiple insulating baffles are provided within the cooling chamber, arranged from top to bottom and dividing the cooling chamber into multiple cooling channels. The outer tub has an inlet and an outlet communicating with the cooling chamber. Each cooling channel has at least one flow port located on the insulating baffle. Adjacent cooling channels are interconnected through the flow port. Refrigerant enters from the inlet, flows through the flow port into each cooling channel, and then flows out from the outlet, thus cooling the inner tub.

[0006] Optionally, two adjacent flow ports are positioned at the maximum permissible spatial interval of the cooling channel.

[0007] Optionally, the outlet and the inlet are respectively located at the upper and lower ends of the outer barrel.

[0008] Optionally, the inlet, the outlet, and the adjacent flow port are located at the maximum permissible spatial interval of the cooling channel.

[0009] Optionally, the outer tub has a bottom edge, and the inner tub has a top edge. When the inner tub is fitted inside the outer tub, the bottom edge, the inner wall of the outer tub, the outer wall of the inner tub, and the top edge form a sealed cooling cavity. Each isolation baffle is annular, and multiple isolation baffles divide the cooling cavity into multiple cooling channels.

[0010] Optionally, the spacing between adjacent isolation baffles is the same.

[0011] Compared with the prior art, the above-mentioned technical solutions in the evaporator structure of the ice cream machine provided by the present invention have at least one of the following technical effects:

[0012] By setting multiple isolation baffles arranged from top to bottom and dividing the cooling chamber into multiple cooling channels, adjacent cooling channels are interconnected through flow ports. The refrigerant enters from the inlet, flows into each cooling channel through the flow port, and then flows out from the outlet, completing the cooling of the inner barrel. Compared with the existing refrigerant flowing in copper pipes, which is separated from the beverage in the container by three layers of wall thickness, this utility model solution is separated by only one layer of inner barrel wall thickness, resulting in high cooling and heat absorption efficiency, fast cooling speed, and lower production cost. The ice cream forming time is greatly shortened, meeting customer needs. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, according to Figure 1-4 As shown, it includes an outer barrel 100 and an inner barrel 200 fitted inside the outer barrel 100. A cooling chamber 300 is formed between the inner barrel 200 and the outer barrel 100. By circulating refrigerant in the cooling chamber 300, the inner wall of the inner barrel 200 is cooled, thereby cooling the beverage inside the inner barrel 200.

[0028] The cooling chamber 300 is provided with multiple isolation baffles 400, which are arranged from top to bottom and divide the cooling chamber 300 into multiple cooling channels 310. The outer barrel 100 is provided with an inlet 110 and an outlet 120 that connect to the cooling chamber 300. Each cooling channel 310 is provided with at least one flow port 320, which is located on the isolation baffles 400. Through the flow port 320, two adjacent cooling channels 310 are connected to each other.

[0029] The refrigerant enters through inlet 110, flows into the first refrigeration channel, and then enters each refrigeration channel step by step through outlet 320 to cool the inner wall of the barrel. Finally, it flows out through outlet 120, completing the refrigeration of the inner barrel 200.

[0030] according to Figure 1-4 As shown, two adjacent flow ports 320 are positioned at the maximum permissible spatial interval within the cooling channel 310. The outlet 120 and inlet 110 are respectively located at the upper and lower ends of the outer tub 100. Positioning them at both ends maximizes refrigerant utilization, allowing the refrigerant to cool the inner tub 200 wall to the maximum extent, thus increasing cooling effect and efficiency. The inlet 110, outlet 120, and adjacent flow ports 320 are positioned at the maximum permissible spatial interval within the cooling channel 310.

[0031] Specifically, the refrigerant enters the first refrigeration channel through inlet 110. Inlet 110 and the adjacent flow port 320 are furthest apart in the first refrigeration channel, allowing the refrigerant to flow throughout the entire channel, resulting in better cooling efficiency. If the refrigeration channel is an annular channel, the projection points of inlet 110 and flow port 320 should be equal to the diameter of the annular channel. Simultaneously, adjacent flow ports 320 are positioned at the maximum permissible spatial interval within the cooling channel 310, ensuring that the refrigerant fills the entire refrigeration channel before entering the next channel through flow port 320, increasing the cooling area and improving cooling effect and efficiency.

[0032] Furthermore, by setting multiple isolation baffles 400 arranged from top to bottom and dividing the cooling chamber 300 into multiple cooling channels 310, adjacent cooling channels 310 are connected to each other through flow ports 320. The refrigerant enters from the inlet 110, enters each cooling channel through the flow ports 320, and then flows out from the outlet 120, completing the cooling of the inner barrel 200. Compared with the existing refrigerant flowing in the copper pipe and separated from the beverage in the container by 3 layers of wall thickness, this utility model solution is separated by only one layer of inner barrel wall thickness, resulting in high cooling and heat absorption efficiency, fast cooling speed, and lower production cost. The ice cream forming time is greatly shortened, meeting the needs of customers.

[0033] The stepped continuous channel formed by the outer barrel 100, the inner barrel 200 and several isolation baffles 400 can effectively guide the refrigerant through, increase the residence time of the refrigerant, make the refrigerant distribution more uniform, and allow it to directly contact the outer wall of the inner barrel 200, thereby better absorbing the heat transferred from the inner barrel 200 and improving the refrigeration efficiency.

[0034] Furthermore, several isolation baffles 400 can be connected to the outer barrel 100 and the inner barrel 200 by welding.

[0035] Furthermore, when the refrigerant density is greater than the air density, the inlet 110 is located above the outlet 120, and when the refrigerant density is less than the air density, the inlet 110 is located below the outlet 120.

[0036] In another embodiment of this utility model, according to Figure 2-4 As shown, the outer barrel 100 has a bottom edge 130 at the bottom. The top of the outer barrel 100 is connected to the outside world, and a bottom edge 130 extends out from the bottom to connect to the outside world through an opening. The inner barrel 200 has a top edge 210 at the top. The top of the inner barrel 200 has an opening to connect to the outside world, and the bottom is sealed to form a receiving cavity. The top edge 210 is used to cooperate with the bottom edge 130, the inner wall of the outer barrel 100, and the outer wall of the inner barrel 200 to form a sealed cooling cavity 300.

[0037] Each isolation baffle 400 is annular, and multiple isolation baffles 400 divide the cooling chamber 300 into multiple cooling channels 310. When the spacing between adjacent isolation baffles 400 is the same, the area of ​​each cooling channel 310 is the same, which allows the coolant to stay in the cooling channel 310 as much as possible and cool the wall of the inner tank 200.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
