Description

Technical Field

[0001] The utility model relates to the technical field of water dispenser equipment, in particular to a water dispenser with a modular design. Background Art

[0002] A water dispenser is a device that facilitates people's drinking. It has at least automatic heating and heat preservation functions. Users do not need to wait for a long time for the drinking water to be heated. They can get hot water or cold water that can be drunk directly anytime and anywhere. Compared with a kettle, it is much more convenient. In existing water dispensers, some new functions will be integrated according to user needs. For example, if the hygiene requirements are high, a filtration system, a disinfection and sterilization system will be integrated into the water dispenser. The more functions a water dispenser has, the more complex its internal structure becomes, and the larger its size becomes. This also leads to an increase in the difficulty of early assembly and later maintenance of the water dispenser.

[0003] For example, the patent with announcement number CN218246813U provides a quick-install lower body of a water dispenser and a water dispenser, providing a quick-install lower body, including a bottom plate, a top plate and two side plates, a front cover plate and a rear cover plate connected therebetween by snap-fitting, the two side plates are connected to the front cover plate and the rear cover plate by plugging, a door hole is processed on the front cover plate so that bottled water can enter through the position of the door hole, and at least one first through hole for a hose to pass through is provided on the upper part of the top plate, one end of the hose is used to connect to the inside of the bottled water, and the other end is used to connect to a pump; a water dispenser with a quick-install lower body is also provided; when shipping, the upper body is shipped as a whole, and the lower body is shipped as parts, which are installed by the customer themselves, reducing the packaging volume and reducing the logistics cost; the upper body and the lower body are connected by snap-fitting, which is convenient to assemble, and the configuration of the middle connecting column and the outer connecting column ensures the overall structural strength of the water dispenser. The "quick installation" of this solution is achieved by "separating the upper and lower bodies" and "plugging in the covers of the lower body", but the other parts of the water dispenser structure, especially the more complex internal functional systems, do not have too many separate designs, and the degree of coupling is still relatively large.

[0004] Therefore, there is an urgent need to provide a water dispenser with a modular design to solve the above technical problems. Summary of the invention

[0005] In view of the problems in the related art, the utility model proposes a water dispenser with a modular design, which realizes distributed assembly through modular layout, thereby reducing assembly difficulty and maintenance cost.

[0006] The utility model is achieved in this way:

[0007] A modular water dispenser includes a bracket module, a panel module, a shell module, a base module, a water storage module and a water channel module;

[0008] The panel module is arranged in the front area of ​​the bracket module, the shell module is arranged in the rear area of ​​the bracket module, and the base module is arranged below the shell module and the bracket module; the panel module, the shell module and the base module are respectively detachably connected to the bracket module; an internal cavity is formed between the panel module, the shell module and the base module; the water channel module is arranged in the internal cavity and is detachably connected to the bracket module; the water channel module is fixed on the bracket module, which is convenient for the optimized design and layout of the pipeline, and the pipeline is not easy to bend.

The final water dispenser has a more compact overall structure, is easy to disassemble, and is highly convenient; each module can be manufactured independently, which is convenient for later maintenance.

[0011] As a further optimization of the above solution, the shell module is provided with a first opening on the side facing forward; the panel module is provided with a second opening on the side facing backward, and the second opening extends to the bottom of the panel module;

[0012] The inner side surface of the shell module is provided with a plurality of evenly distributed extensions on the left and right sides of the first opening, respectively. The extensions extend toward the front of the shell module, and the ends of the extensions protrude toward the outside to form hook buckles; the inner side surface of the panel module is provided with a plurality of evenly distributed convex buckles on the left and right sides of the second opening, respectively.

[0013] The plurality of protruding buckle parts and the plurality of hook buckle parts cooperate with each other one by one, so that the shell module and the panel module are tightly connected.

[0014] During assembly, the bottom of the panel module slides downward and covers the extension of the shell module. At this time, the hook portion faces the left and right inner walls of the panel module, and the hook portion abuts against the front side of the convex portion; at this time, the edge of the first opening facing the front side and the edge of the second opening facing the rear side fit and abut against each other, forming a smooth transition between the outer sides of the shell module and the panel module.

[0015] The design of the extension part, the hook part and the convex buckle part can improve the convenience of assembling the shell module and the panel module, and at the same time improve the overall tightness of the water dispenser.

[0016] As a further optimization of the above solution, a limiting flange protruding upward is provided along the top front edge of the bracket module; the bottom of the panel module abuts against the front side of the limiting flange;

[0017] The inner side surface of the housing module is also provided with a plurality of evenly distributed limiting parts on the left and right sides of the first opening; the limiting parts protrude and extend toward the front; wherein the extending part is located at the upper half of the first opening, and the limiting part is located at the lower half of the first opening;

[0018] The left and right sides of the bracket module are respectively provided with two limiting grooves with openings facing backwards and arranged vertically; when the shell module and the bracket module are matched, the limiting part is embedded in the limiting grooves.

[0019] On the basis of the cooperation between the shell module and the panel module through the hook and convex buckle parts, a limiting part and a limiting groove are further provided, which can improve the tight connection between the shell module, the panel module and the bracket module after cooperation, and ensure the stability of the structural connection. The limiting part and the hook and buckle part are located on the inner side of the shell module, and the appearance of the water dispenser body after cooperation presents a smooth transition, taking into account the aesthetics.

[0021] As a further optimization of the above solution, it also includes a water outlet module, the water outlet is arranged on the water outlet module; a fourth opening is arranged at the bottom of the first support part; and the water outlet module is adapted and fixed at the fourth opening.

[0022] As a further optimization of the above solution, the water channel module includes a water pump; the input end of the water pump is connected to the water storage module through a pipeline, and the output end of the water pump is connected to the water outlet through a pipeline.

[0023] As a further optimization of the above solution, a glass tube segment is provided on the pipeline between the water pump and the water outlet; the water channel module also includes a fixed bracket and at least one UV lamp; the fixed bracket is detachably connected to the bracket module; the UV lamp is fixed on the bracket and is located on the peripheral side of the glass tube segment.

[0024] UV lamp refers to ultraviolet lamp tube. Since there is a waterway between the water pump and the water outlet, bacteria and viruses are easy to attach to this waterway. It is difficult to achieve the antibacterial effect by just relying on instantaneous flow of boiling water or hot water. Setting up a UV lamp, a glass tube end and a fixed bracket can sterilize and disinfect the liquid passing through the glass pipe; in conventional technology, the UV lamp is set in the waterway, but it is easy to be damaged by hot water. This solution sets the UV lamp outside the pipeline to avoid the problems existing in the existing technology.

[0025] As a further optimization of the above solution, the water channel module further includes a solenoid valve and a three-way adapter; the three ports included in the three-way adapter are respectively connected to the output end of the water pump, the input end of the solenoid valve and the water outlet; the output end of the solenoid valve is connected to the waste water tank;

[0026] A concave mounting groove is provided on a front side of the bracket module, and the waste water tank is embedded and fixed in the mounting groove.

[0027] When the user takes water, the water dispenser pumps water to the outlet through the water pump; after the user takes water, the water pump stops working, and water accumulates in the water path from the water pump to the outlet. After a long time, the accumulated water will produce bacteria; by setting up a solenoid valve and a waste water tank, the accumulated water can be discharged after the water pump stops working.

[0028] When the user uses water again, he can also put some hot water into the pipe behind the water pump for disinfection, and then discharge the water used for disinfection through the solenoid valve.

[0029] As a further optimization of the above solution, a second support portion extending toward the front is provided at the bottom of the bracket module, and a weighing module is supported between the second support portion and the base module below; a detachable water tray module is also provided on the second support portion. The second support portion is integrally connected to the bracket module, which can provide a stable support for the weighing module, and has sufficient strength to ensure that the sensing end (varistor) of the weighing module will not exceed the weighing data error due to deformation of plastic parts or assembly tolerance.

[0030] The water receiving tray module is used to receive water dripping from the water outlet to avoid water accumulation and turbulence; when a water cup is placed on the water receiving tray module to receive water, quantitative water discharge can be achieved through the coordinated control of the weighing module and the water pump.

[0031] As a further optimization of the above scheme, the water storage module has an independent heating circuit inside; a water valve is provided at the bottom of the water storage module; a detachable coupler is provided at the bottom of the accommodating portion; the coupler has an electrical connection interface and a water circuit connection interface; the electrical connection interface is used to connect the heating circuit; the water circuit connection interface is used to connect the water valve and the water circuit module.

[0032] The coupler is provided so that the water storage module and the body of the water dispenser can be quickly separated and assembled, making it convenient for users to take away and replenish water.

[0033] The beneficial effects are as follows:

[0034] The utility model provides a water dispenser with a modular design, in which each component and structure of the water dispenser is modularly designed, and the bracket module is used as the skeleton structure, and most of the other modules are assembled and fixed on the bracket module. Compared with conventional water dispensers, the modules of the water dispenser improved by this scheme can be independently manufactured and flexibly combined, with high assembly efficiency, convenient later maintenance and upgrading of each module, and the structure of the whole machine after assembly is compact; the water dispenser can be disassembled into multiple modules for transportation and then assembled, and has high portability.
