Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a double-layer material tank structure and frozen food manufacturing equipment. Background Technology

[0002] As a core component of cold beverage equipment, slush machines are widely used in dessert shops, fast food chains, coffee shops, and home consumption scenarios. Slush machines produce soft, smooth ice cream or sorbet products by stirring and outputting pre-cooled ingredients at low temperatures.

[0003] The material tank is a functional component of the slush machine responsible for holding, mixing, and controlling the temperature of raw materials. Its structural design directly affects the thermal efficiency, energy consumption, and hygiene safety of the equipment. Traditional slush machine material tanks are mostly made of single-layer stainless steel. The low-temperature raw materials inside the tank exchange heat with the external hot air through the single-layer wall, resulting in a large loss of cold air. This causes ice cream or sorbet products to melt prematurely, increasing the energy consumption of the slush machine. Moreover, the external air condenses on the outer surface of the tank, forming a large amount of condensate, which poses a risk of bacterial growth. This not only increases the burden of cleaning the equipment but may also drip and contaminate the raw materials. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a double-layer material tank structure to reduce cold loss and reduce or avoid condensation adhering to the outer surface to reduce the cleaning burden; the second objective is to provide a frozen food manufacturing equipment using the above-mentioned double-layer material tank structure.

[0005] A double-layer material barrel structure according to a first aspect of the present invention includes: an inner barrel and an outer barrel sleeved on the outside of the inner barrel. There are installation gaps between the outer peripheral wall of the inner barrel and the inner peripheral wall of the outer barrel, and between the bottom wall of the inner barrel and the bottom wall of the outer barrel. The inner barrel is used to sleeve the outside of the refrigeration component of a cold beverage manufacturing equipment.

[0006] The double-layer material hopper structure according to the embodiments of this utility model has at least the following beneficial effects:

[0007] The above-described double-layer material tank structure utilizes the inner tank to hold the raw materials for cold drinks. The installation gap separates the bottom wall of the inner tank from the bottom wall of the outer tank, and the outer peripheral wall of the inner tank from the inner peripheral wall of the outer tank. This installation gap serves to isolate heat exchange, thereby reducing cold loss and helping to reduce the energy consumption of cold drink manufacturing equipment. It also reduces or avoids condensation adhering to the outer surface, thus reducing the cleaning burden.

[0008] In some embodiments of this utility model, a support member is provided between the outer peripheral wall of the inner tub and the inner peripheral wall of the outer tub to keep them relatively fixed, and the support member is made of heat-insulating material.

[0009] In some embodiments of this utility model, the support member includes at least two first sealing rings spaced apart along the axial direction of the inner tub and the outer tub, wherein the first sealing rings are tightly fitted to the outer peripheral wall of the inner tub and the inner peripheral wall of the outer tub.

[0010] In some embodiments of this utility model, the outer peripheral wall of the inner tub is provided with two annular positioning grooves that correspond one-to-one with the first sealing ring. The annular positioning grooves are recessed radially inward along the outer peripheral wall of the inner tub. The first sealing ring is installed inside the annular positioning groove, and the outer peripheral wall of the first sealing ring elastically abuts against the inner peripheral wall of the outer tub.

[0011] In some embodiments of this utility model, the outer peripheral wall of the first sealing ring is provided with at least two first sealing rings with a triangular cross-section.

[0012] In some embodiments of this utility model, the inner barrel and the outer barrel are both arranged in a vertical direction. The lower end of the inner barrel is provided with a downwardly extending discharge pipe, and the lower end of the outer barrel is provided with a clearance hole for the discharge pipe to pass through. The double-layer barrel structure also includes a switch structure for opening or closing the discharge pipe.

[0013] In some embodiments of this utility model, the switch structure is a plug that can be detachably inserted into the discharge pipe. The plug has a second sealing ring that is tightly fitted to the inner circumferential wall of the discharge pipe in multiple spaced rings. The lower end of the plug has a tension column that extends out from below the outer barrel.

[0014] In some embodiments of this utility model, the inner bottom wall of the outer barrel is provided with a circular wall surrounding the outside of the discharge pipe, and the outer peripheral wall of the middle part of the discharge pipe is formed with a limiting flange that abuts against the inner peripheral wall of the circular wall. A second sealing ring is provided between the limiting flange and the inner bottom wall of the outer barrel.

[0015] In some embodiments of this utility model, a handle is provided protruding from the outer peripheral wall of the outer barrel.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See Figure 1 , Figure 2 and Figure 4 The present invention discloses a double-layer material barrel structure, comprising: an inner barrel 100 and an outer barrel 200 sleeved on the outside of the inner barrel 100. There are installation gaps 300 between the outer peripheral wall of the inner barrel 100 and the inner peripheral wall of the outer barrel 200, and between the bottom wall of the inner barrel 100 and the bottom wall of the outer barrel 200. The inner barrel 100 is used to sleeve the outside of the refrigeration component of the cold beverage manufacturing equipment.

[0030] The above-described double-layer material tank structure uses the inner tank 100 to hold the cold beverage raw materials. The installation gap 300 separates the bottom wall of the inner tank 100 from the bottom wall of the outer tank 200, and the outer peripheral wall of the inner tank 100 from the inner peripheral wall of the outer tank 200. This installation gap 300 serves to insulate against heat exchange, thereby reducing cold loss. There is no contact between the inner tank 100 and the outer tank 200 at multiple locations, which helps to reduce the energy consumption of the cold beverage manufacturing equipment and reduce or avoid condensation adhering to the outer surface to reduce the cleaning burden.

[0031] See Figure 1 and Figure 2In some embodiments of this utility model, a support member 400 is provided between the outer peripheral wall of the inner tub 100 and the inner peripheral wall of the outer tub 200 to keep them relatively fixed. The support member 400 is made of heat-insulating material. It is understood that the support member 400 is at least partially located within the installation gap 300 to stably install the outer tub 200 outside the inner tub 100. The heat-insulating material of the support member 400 prevents the cold air from the inner tub 100 from being transferred to the outside air sequentially through the support member 400 and the outer tub 200. The support member 400 serves both a supporting and heat-insulating function. Of course, in other embodiments, the inner tub 100 and the outer tub 200 can be fixed by welding, but the weld is a good conductor of heat, which can easily cause excessive localized cold loss.

[0032] See Figure 1 and Figure 2 In some embodiments of this utility model, the support member 400 includes at least two first sealing rings 410 spaced apart along the axial direction of the inner tub 100 and the outer tub 200. The first sealing rings 410 are tightly fitted to the outer peripheral wall of the inner tub 100 and the inner peripheral wall of the outer tub 200. By using the interference fit between the first sealing rings 410 and the inner tub 100 and the outer tub 200 respectively, assembly and production are very convenient, while also reducing production and assembly costs. The at least two first sealing rings 410 spaced apart along the axial direction of the inner tub 100 and the outer tub 200 can prevent relative tilting of the inner tub 100 and the outer tub 200.

[0033] Of course, in other embodiments, the support 400 can also be replaced by a fastening screw made of plastic material, which is used to tighten and fix the inner tub 100 and the outer tub 200.

[0034] See Figure 1 and Figure 2 In some embodiments of this utility model, to prevent the first sealing ring 410 from shifting relative to the inner tub 100 and the outer tub 200, thereby limiting relative movement between the inner tub 100 and the outer tub 200, the outer peripheral wall of the inner tub 100 is provided with two annular positioning grooves 110 corresponding one-to-one with the first sealing ring 410. The annular positioning grooves 110 are radially recessed inward along the outer peripheral wall of the inner tub 100. The first sealing ring 410 is installed within the annular positioning grooves 110, and the outer peripheral wall of the first sealing ring 410 elastically abuts against the inner peripheral wall of the outer tub 200. The cross-sectional shape and size of the annular positioning grooves 110 match the cross-sectional shape and size of the first sealing ring 410, preventing the first sealing ring 410 from shifting relative to the annular positioning grooves 110 and ensuring that the first sealing ring 410 is stably supported between the inner tub 100 and the outer tub 200.

[0035] In some embodiments of this utility model, in order to further reduce the possibility of relative movement between the inner tub 100 and the outer tub 200, the outer peripheral wall of the first sealing ring 410 is provided with at least two first sealing rings 411 with triangular cross-sections. The first sealing rings 411 are clamped between the inner peripheral wall of the outer tub 200 and the circular positioning groove 110 to produce elastic deformation.

[0036] See Figures 1 to 3 In some embodiments of this utility model, both the inner barrel 100 and the outer barrel 200 are arranged vertically. The lower end of the inner barrel 100 is provided with a downwardly extending discharge pipe 120, and the lower end of the outer barrel 200 is provided with a clearance hole 210 for the discharge pipe 120 to pass through. The double-layer barrel structure also includes a switch structure 500 for opening or closing the discharge pipe 120. When the user uses the switch structure 500 to open the discharge pipe 120, the cold drink or smoothie in the inner barrel 100 can be discharged downwards. The user can operate the switch structure 500 to open or close the discharge pipe 120 according to the required amount. Of course, in some embodiments, the double-layer barrel structure can also be detachably connected to the outside of the refrigeration component of the cold drink manufacturing equipment.

[0037] See Figure 3 In some embodiments of this utility model, the switch structure 500 is a plug that can be detachably inserted into the discharge pipe 120. The plug has multiple interlocking second sealing rings 510 that fit tightly against the inner circumferential wall of the discharge pipe 120. The lower end of the plug has a tension post extending below the outer barrel 200. The user can simply grasp the tension post and pull it downwards to detach the plug, and grasp the tension post and insert it upwards to block the discharge pipe 120. The plug is generally made of rubber and also has a heat insulation effect. Of course, in other embodiments, the switch structure 500 can also be replaced by a valve for opening and closing the lower end of the discharge pipe 120.

[0038] It should be noted that there is a clearance between the discharge pipe 120 and the clearance hole 210, which allows dust or external air to enter the installation gap 300. When the external air liquefies on the outer peripheral wall of the inner tank 100, it can cause water accumulation, leading to bacterial growth. See also Figure 3 In some embodiments of this utility model, the inner bottom wall of the outer barrel 200 is provided with a circular annular wall 220 surrounding the outside of the discharge pipe 120. The outer peripheral wall of the middle part of the discharge pipe 120 is formed with a limiting flange 121 that abuts against the inner peripheral wall of the circular annular wall 220. A second sealing ring 600 is provided between the limiting flange 121 and the inner bottom wall of the outer barrel 200. The second sealing ring 600 is used to prevent external foreign objects from entering the installation gap 300 from between the discharge pipe 120 and the clearance hole 210.

[0039] See Figure 1 and Figure 2 In some embodiments of this utility model, a handle 230 is provided protruding from the outer peripheral wall of the outer barrel 200. It should be noted that even with a double-layer barrel structure, a certain amount of cold air is inevitably transferred to the outer peripheral wall of the outer barrel 200, resulting in a frozen feel and a small amount of water droplets. The handle 230 is provided to prevent the user's palms from freezing and to prevent the user's palms from getting wet.

[0040] See Figure 4 This utility model also discloses a frozen food manufacturing equipment, including a main body 700, on which a refrigeration evaporator 710 is provided, and the main body 700 has a double-layer material tank structure sleeved on the outside of the refrigeration evaporator 710. The frozen food manufacturing equipment with the above structure utilizes the double-layer material tank structure to reduce cold loss, which helps to reduce the energy consumption of the frozen food manufacturing equipment and reduces or avoids condensation adhering to the outer surface, thus reducing the cleaning burden.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
