A high-efficiency stainless steel evaporator for smoothies

Abstract

This utility model discloses a high-efficiency stainless steel evaporator for a smoothie machine, belonging to the technical field of smoothie machine technology. It includes an evaporator cylinder, with an inner cylinder fixedly connected to the inner cavity of the evaporator cylinder. The outer wall of the inner cylinder has circularly arrayed flow cavities. This utility model utilizes the circularly arrayed arc-shaped flow cavities on the outer wall of the inner cylinder, combined with U-shaped cavities at the upper and lower ends, to form a continuous channel. Compared to the annularly coiled copper tubes in existing devices, this significantly increases the contact area with the inner wall of the evaporator cylinder, allowing the refrigerant to evenly cover the interior of the evaporator cylinder, effectively solving the problem of uneven cooling.

Description

Technical Field

[0001] This utility model belongs to the technical field of smoothie machines, specifically relating to a high-efficiency stainless steel evaporator for smoothie machines. Background Technology

[0002] In the operation of a smoothie maker, the evaporator is the key component that enables the core function of "no pre-made ice". It, together with the compressor and condenser, forms a refrigeration system. By directly absorbing the heat of the liquid ingredients in the container, it quickly freezes them into semi-solid ice crystals, providing frozen raw materials for the blades to crush the ingredients. Finally, in conjunction with the stirring system, the ice crystals are mixed with other ingredients to form a smooth smoothie. This is the core support for this type of smoothie maker to achieve the integrated operation of "instant ice making + blending into smoothie", so that the production process does not rely on pre-prepared ice.

[0003] Existing evaporators mainly consist of a stainless steel cylinder and copper tubes coiled inside the cylinder. Their working principle involves refrigerant transported through the copper tubes absorbing heat from the outside of the cylinder, thus achieving an ice-making effect. However, because the copper tubes are coiled in rings inside the cylinder, the contact area between the copper tubes and the inner wall of the cylinder is very limited, resulting in uneven cooling. Furthermore, during heat absorption, the refrigerant must pass through both the copper tubes and the cylinder before contacting the external liquid, which significantly reduces the refrigerant's cooling efficiency.

[0004] Therefore, there is an urgent need for a high-efficiency stainless steel evaporator for smoothies to solve the refrigeration efficiency problem mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency stainless steel evaporator for a smoothie machine to solve the problems mentioned in the background art.

[0007] In a preferred embodiment, the flow cavity is arc-shaped and connected to the inner wall of the evaporator cylinder to form a sealed channel, and the flow cavities are connected sequentially through U-shaped cavities opened at the upper and lower ends.

[0008] In a preferred embodiment, the input tube is connected to the lower part of the first flow cavity, and the output tube is connected to the upper part of the last flow cavity.

[0010] In a preferred embodiment, the mounting hole penetrates the bottom of the evaporator cylinder, the temperature sensing hole is connected to the inner cavity of the evaporator cylinder, and the central axis of the temperature sensing hole is parallel to the central axis of the mounting hole.

[0011] In a preferred embodiment, the mounting plate and the outer wall of the evaporator cylinder are integrally formed, the inner wall of the connecting groove is provided with anti-slip texture, and the diameter of the connecting groove is compatible with the diameter of conventional fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an arc-shaped flow cavity arranged in a circular array on the outer wall of the inner cylinder, combined with U-shaped cavities at the upper and lower ends to form a continuous channel. Compared to the annularly coiled copper tubes in existing devices, this significantly increases the contact area with the inner wall of the evaporator cylinder, allowing the refrigerant to evenly cover the interior of the evaporator cylinder and effectively solving the problem of uneven cooling.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-4 This utility model provides a high-efficiency stainless steel evaporator for a smoothie machine, including an evaporator cylinder 1. An inner cylinder 2 is fixedly connected to the inner cavity of the evaporator cylinder 1. Flow chambers 3 are arranged in a circular array on the outer wall of the inner cylinder 2. U-shaped cavities 4 are respectively formed at the upper and lower ends of the flow chambers 3. An input pipe 5 is fixedly connected to the inner wall of the inner cylinder 2. An input pipe 6 is fixedly connected to the end of the input pipe 5 away from the inner cylinder 2. An output pipe 7 is fixedly connected to the inner wall of the inner cylinder 2. An installation hole 8 is formed at the bottom of the evaporator cylinder 1. A temperature sensing hole 9 is formed on the outer side of the installation hole 8 and located at the bottom of the evaporator cylinder 1. An installation piece 10 is fixedly connected to the outer wall of the evaporator cylinder 1. A connecting groove 11 is formed on the side surface of the installation piece 10. The evaporator cylinder 1 serves as the main structure, and the inner cylinder 2 fixed within its cavity forms a double-layer structure, enhancing the overall strength and stability. The circular array of flow chambers 3 on the outer wall of the inner cylinder 2 provides a flow channel for the refrigerant. Combined with the U-shaped chambers 4 at the upper and lower ends, this allows the refrigerant to flow in an orderly manner. Inlet pipe 1 5 and inlet pipe 2 6 are used for refrigerant input, and outlet pipe 7 is used for refrigerant output; the three work together to ensure refrigerant circulation. The mounting hole 8 at the bottom of the evaporator cylinder 1 facilitates the installation and fixation of the evaporator. By installing a temperature probe inside the temperature sensing hole 9, the temperature of the ice-making liquid can be monitored in real time. The mounting plate 10 on the outer wall of the evaporator cylinder 1 and the connecting groove 11 on its side surface facilitate the connection of the evaporator to other components, making the installation more stable and reliable.

[0022] Specifically, such as Figure 1 and Figure 4As shown, the flow chamber 3 is arc-shaped and connects to the inner wall of the evaporator cylinder 1 to form a sealed channel. The flow chambers 3 are connected sequentially through U-shaped cavities 4 at both the upper and lower ends. This arc-shaped flow chamber 3, connected to the inner wall of the evaporator cylinder 1 to form a sealed channel, not only increases the refrigerant flow path length and prolongs the contact time between the refrigerant and the inner cylinder 2, thereby improving heat exchange efficiency, but also ensures that the refrigerant will not leak, guaranteeing the stability of the cooling effect. The sequential connection of the flow chambers 3 through the U-shaped cavities 4 at both the upper and lower ends allows the refrigerant to flow sequentially in each flow chamber 3, forming a continuous circulation path, further optimizing the refrigerant flow distribution and improving the overall cooling efficiency.

[0023] The inlet pipe 5 is connected to the lower part of the first flow chamber 3, and the outlet pipe 7 is connected to the upper part of the last flow chamber 3. The refrigerant enters the first flow chamber 3 from the bottom, flows upward under pressure, passes through each flow chamber 3 in sequence, and finally flows out from the upper outlet pipe 7. This design allows the refrigerant to flow fully within the flow chambers 3 and make full contact with the inner cylinder 2, improving the efficiency of heat exchange and thus enhancing the evaporator's cooling performance.

[0024] Specifically, such as Figure 2 and Figure 3 As shown, input pipe 2 6 is connected to input pipe 1 5, and the radius of input pipe 2 6 is smaller than that of input pipe 1 5. The end of input pipe 2 6 away from input pipe 1 5 is spirally sleeved on the outside of output pipe 7. This structure enables the high-temperature, low-pressure gaseous refrigerant in output pipe 7 to exchange heat with the low-temperature gas-liquid mixture refrigerant in input pipe 2 6. This not only further cools the refrigerant about to enter flow chamber 3, increasing its latent heat of vaporization and improving its cooling capacity, but also lowers the temperature of the refrigerant returning to the compressor, preventing the compression efficiency from decreasing due to excessively high temperature of the gaseous refrigerant before it enters the compressor.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the mounting hole 8 penetrates the bottom of the evaporator cylinder 1, and the temperature sensing hole 9 is connected to the inner cavity of the evaporator cylinder 1. The central axis of the temperature sensing hole 9 is parallel to the central axis of the mounting hole 8. The mounting hole 8 penetrates the bottom of the evaporator cylinder 1, which facilitates the secure installation of the evaporator on the smoothie machine base using bolts or other connecting parts, ensuring the stability of the equipment during operation.

[0026] Specifically, such as Figure 2 and Figure 3As shown, the mounting plate 10 and the outer wall of the evaporator cylinder 1 are integrally formed. The inner wall of the connecting groove 11 has anti-slip texture, and the diameter of the connecting groove 11 is compatible with the diameter of conventional fixing bolts. The integral forming of the mounting plate 10 and the outer wall of the evaporator cylinder 1 enhances the connection strength, enabling it to withstand vibrations and external impacts during equipment operation, ensuring installation stability. The anti-slip texture on the inner wall of the connecting groove 11, compatible with the diameter of conventional fixing bolts, increases the friction between the bolt and the connecting groove 11, preventing bolt loosening, and also facilitates quick positioning and installation, improving assembly efficiency and connection reliability.

[0027] Working principle and usage process of this utility model:

[0028] The staff first used bolts to securely install the evaporator cylinder 1 onto the slush machine base through the mounting hole 8 and the connecting groove 11 on the mounting plate 10, and then installed the temperature sensor probe at the bottom of the evaporator cylinder 1 through the temperature sensor hole 9.

[0029] After the refrigeration system is started, the high-pressure room-temperature liquid refrigerant from the condenser enters through the second inlet pipe 6. Due to the capillary throttling effect of the second inlet pipe 6, it expands into a low-temperature, low-pressure gas-liquid mixture. Then, it flows into the lower part of the first flow chamber 3 through the first inlet pipe 5. Subsequently, it flows upward along the arc-shaped channel in the flow chamber 3 and enters the adjacent flow chambers 3 in sequence through the U-shaped cavity 4, forming a spiral upward path. During the process, it absorbs the heat transferred from the inner cylinder 2 of the cylinder and gradually vaporizes and heats up. The fully vaporized high-temperature, low-pressure gaseous refrigerant enters the output pipe 7 from the upper part of the last flow chamber 3. The spiral connection structure between the output pipe 7 and the second inlet pipe 6 realizes heat exchange, further cooling the input refrigerant and superheating the output refrigerant to improve energy efficiency.

[0030] Afterwards, the gaseous refrigerant flows out from the output pipe 7 and returns to the compressor to complete the cycle. The inner cylinder 2 of the cylinder absorbs heat and is kept at a low temperature for ice making. During use, the operator can monitor the temperature of the ice-making liquid in real time through the temperature sensor installed inside the temperature sensor hole 9, which facilitates better ice making.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
