Description

Technical Field

[0001] The invention belongs to the technical field of wine and beverage drinking equipment and relates to a liquid outlet pipe fixing structure of a beverage machine. Background Art

[0002] The beverage machine includes a beer refrigerator, which has a built-in refrigeration system that can cool the beer. It targets existing wine barrels, a tool for holding alcoholic beverages, which are generally divided into metal barrels and plastic barrels. Plastic barrels are low-cost and lightweight. A wine spear is provided at the barrel mouth, and a core is provided inside the wine spear, which can seal the alcoholic beverage inside the barrel. To match this, the beverage machine also has components such as a cooling aluminum base and a faucet. A dispensing head is installed at the bottom of the cooling aluminum base, and a disposable liquid outlet pipe is installed on the cooling aluminum base, one end of which is connected to the dispensing head and the other end is connected to the faucet. When in use, the wine barrel is inverted and inserted into the cooling aluminum base. The dispensing head can cooperate with the wine spear on the wine barrel, and the refrigeration system cools the cooling aluminum base, which in turn cools the wine barrel, thereby obtaining the cooled alcoholic beverage.

[0003] As disclosed in the patent document (application number: 202210194159.6), the beverage dispensing assembly and beverage container include a dispenser and a beverage container, the dispenser includes a shell, wherein the shell is provided with a receiving portion for receiving at least part of the container, wherein the container is positioned in the dispenser, and the neck portion and the shoulder portion face downward, so that the neck portion and at least a portion of the shoulder portion are received in the receiving portion, and the receiving portion can cool the beverage container, but since the barrel mouth of the beverage container is located downward at the bottom of the receiving portion, the wine tube is required to extend from the bottom of the receiving portion to the upper end of the receiving portion, so a long strip-shaped mounting groove is opened on the receiving portion, and the disposable wine tube is stuck in the mounting groove. Since the disposable wine tube is made of soft plastic, it is directly in contact with the groove wall of the mounting groove, and the temperature of the receiving portion is low, which will cause the temperature of the wine in the disposable wine tube to be too low or even frozen, affecting the cooling effect and the quality of the wine. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a liquid outlet pipe fixing structure for a beverage machine to solve the problem that the existing beverage machine has poor refrigeration effect and affects the quality of the beverage.

[0005] The objectives of the present invention can be achieved through the following technical solutions: a liquid outlet pipe fixing structure for a beverage machine, the beverage machine includes a cylindrical refrigeration seat, and an elongated mounting groove is provided on the inner wall of the refrigeration seat, characterized in that the fixing structure includes an elongated thermal insulation strip made of non-metallic material, and a fixing groove is provided on one side surface of the thermal insulation strip along the length direction, and a positioning member capable of fixing the liquid outlet pipe in the fixing groove is also provided on the thermal insulation strip, and the side of the thermal insulation strip opposite to the notch of the fixing groove is embedded in the mounting groove, and the thermal insulation strip is fixed to the refrigeration seat so that the notch of the fixing groove faces the inner cavity of the refrigeration seat, and an air hole is also provided on the inner side surface of the fixing groove that penetrates to the outer side surface of the thermal insulation strip.

[0006] The thermal insulation strip is embedded in the installation groove and fixed to the refrigeration base, the disposable liquid outlet pipe is embedded in the fixed groove and fixed by the positioning piece to ensure the stability of the disposable liquid outlet pipe. The thermal insulation strip is made of non-metallic material with relatively low thermal conductivity. The thermal insulation strip is embedded in the installation groove on the side opposite to the notch of the fixed groove, and the notch of the fixed groove faces the inner cavity of the refrigeration base, that is, the thermal insulation strip is blocked between the disposable liquid outlet pipe and the installation groove wall of the refrigeration base. The disposable liquid outlet pipe does not contact the refrigeration base. The thermal insulation strip plays a role in isolating the cold, avoiding the cold of the refrigeration base directly transferring to the disposable liquid outlet pipe, resulting in the temperature of the wine passing through being too low, thereby improving the refrigeration effect and ensuring the quality of the wine. Furthermore, when no wine is taken, some of the wine will remain in the disposable liquid outlet pipe. Since this part of the wine is far away from the wine barrel and is blocked by the insulation strip, the temperature of the wine in the disposable liquid outlet pipe will rise due to long-term storage, and the cooling effect will be lost. For this reason, the present application, on the basis of taking into account insulation, opens air holes on the insulation strip. The cold energy of the refrigeration seat can enter the fixed groove through the air holes and be transferred to the disposable liquid outlet pipe, thereby keeping the wine in the disposable liquid outlet pipe cold and ensuring the cooling effect of the wine that remains in the disposable liquid outlet pipe for a long time. In summary, the present application avoids direct contact between the disposable liquid outlet pipe and the refrigeration seat, which causes the temperature of the wine in the disposable liquid outlet pipe to be too low, and thus causes the problem of poor cooling effect of the wine remaining in the disposable liquid outlet pipe when no wine is taken. Air holes are opened on the insulation strip to obtain part of the cooling energy. This part of the cooling energy will not affect the wine passing through, but can keep the wine that remains in the disposable liquid outlet pipe for a long time cold, thereby improving the cooling effect and ensuring the quality of the wine.

[0007] In the aforementioned beverage dispenser liquid outlet pipe fixing structure, the insulation strip has a U-shaped cross-section, with the edges of the fixing slot adjacent to the edges of the mounting slot. The edges of the insulation strip extend as far as possible toward the mounting slot to provide greater shielding, preventing contact between the disposable liquid outlet pipe and the refrigeration base.

[0008] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, both sides of the insulation strip are folded outward to form abutment ridges. Concave shoulders are formed on both sides of the mounting slot, and the two abutment ridges rest against the two concave shoulders. The sides of the abutment ridges facing the inner cavity of the cooling base smoothly transition to the inner wall of the cooling base. The abutment ridges allow the insulation strip to extend further to both sides, preventing the disposable liquid outlet pipe from contacting the cooling base. The abutment ridges rest against the concave shoulders, ensuring the stability of the insulation strip.

[0009] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, the insulation strips are arranged vertically, with the upper end of the fixing groove extending through the upper end surface of the insulation strip. There are at least two sets of positioning members, one of which is located at the upper end of the fixing groove. After extending from the upper end of the insulation strip, the disposable liquid outlet pipe needs to enter the faucet and cooperate with the opening and closing of the faucet. To this end, a set of positioning members is provided at the upper end of the fixing groove to prevent the disposable liquid outlet pipe from being pulled during faucet operation, causing it to move within the fixing groove, thereby ensuring its stability.

[0010] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, each set of positioning members includes two locking pins located on the bottom surface of the fixing slot and facing the slot opening. The two locking pins are respectively adjacent to the two side walls of the fixing slot and are arranged opposite each other. The two locking pins have relatively protruding locking protrusions on the opposite side surfaces of the outer ends of the two locking pins. The elongated locking pins have a certain degree of elasticity. When installing a disposable liquid outlet pipe, the locking protrusions can be pushed toward both sides until the disposable liquid outlet pipe fits between the two locking pins. After resetting, the two locking protrusions on the locking pins can limit the disposable liquid outlet pipe's position, ensuring its stability. The above structure also facilitates the removal of the disposable liquid outlet pipe.

[0011] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, an air cavity is formed between the outer side of the insulation strip and the wall of the mounting slot, and the outer end of the air hole communicates with the cavity. The mounting slot wall of the refrigeration base can dissipate cold air into the cavity, generating cold air within the cavity. This air then flows toward the air hole, enters the insulation strip's fixing slot through the air hole, and cools any remaining liquid in the disposable liquid outlet pipe, ensuring a cooling effect on the liquid.

[0012] In the aforementioned beverage dispenser liquid outlet pipe fixing structure, there are two air holes, each located on the inner side of the same pair of two locking pins, with the inner openings of the two air holes facing the two locking protrusions. The openings of the air holes face the locking protrusions, meaning that the locking protrusions can block the openings of the air holes, preventing foreign matter from entering the air cavity.

[0013] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, the insulation strip comprises a straight upper section and a curved lower section, with the air holes located at the junction of the two. The straight upper section fits the straight cylindrical wall of the wine barrel, while the curved lower section fits the curved end surface of the wine barrel. The air holes are located at the junction of the two, roughly in the middle of the insulation strip, ensuring more even cooling capacity transfer to both ends, improving the cooling effect.

[0014] In the aforementioned beverage dispenser liquid outlet pipe fixing structure, the upper end of the thermal insulation strip has an outwardly protruding upper fastening plate, which is provided with an upper snap-in opening. The upper end surface of the refrigeration base has a snap-in groove, and the bottom surface of the snap-in groove has an upwardly protruding upper clamping block. The upper fastening plate is snapped into the snap-in groove, and the upper clamping block is snapped into the upper snap-in opening. When the upper fastening plate is pushed outward, it deforms upward and, when in position, snaps downward onto the bottom surface of the snap-in groove, snapping the upper clamping block into the upper snap-in opening, thereby achieving a detachable connection of the thermal insulation strip.

[0015] In the aforementioned beverage dispenser's liquid outlet pipe fixing structure, the lower end of the thermal insulation strip has an outwardly protruding lower fastening plate with a lower snap-in opening. The lower end surface of the refrigeration base has a downwardly protruding lower clamping block. The lower fastening plate rests against the lower end surface of the refrigeration base, and the lower clamping block is snap-fitted into the lower snap-in opening. Similarly, by pushing the lower fastening plate outward, the lower fastening plate can also be deformed downward until the lower clamping block snaps into the lower snap-in opening, achieving a detachable connection of the thermal insulation strip.

[0016] Compared with the prior art, the liquid outlet pipe fixing structure of the beverage machine has the following advantages:

[0017] 1. Since the insulation strip is made of non-metallic material, the thermal conductivity efficiency is relatively low. The insulation strip is blocked between the disposable liquid outlet pipe and the installation groove wall of the refrigeration base. The disposable liquid outlet pipe does not contact the refrigeration base, avoiding the direct transfer of the cold capacity of the refrigeration base to the disposable liquid outlet pipe, resulting in the temperature of the wine passing through being too low, thereby improving the refrigeration effect and ensuring the quality of the wine.

[0018] 2. Since air holes are opened on the insulation strip, the cold energy of the refrigeration base can enter the fixed groove through the air holes and be transferred to the disposable liquid outlet pipe, so as to keep the wine in the disposable liquid outlet pipe cold and ensure the refrigeration effect of the wine remaining in the disposable liquid outlet pipe for a long time.

[0019] 3. Since an air cavity is formed between the outer side of the insulation strip and the wall of the installation groove, the wall of the installation groove of the refrigeration seat can dissipate cold air to the air cavity, generating cold air in the air cavity, which then flows to the air holes and enters the fixed groove of the insulation strip through the air holes, cooling the wine and water that has remained in the disposable liquid outlet pipe for a long time, thereby ensuring the cooling effect of the wine and water.
