Description

Technical Field

[0001] This utility model relates to the technical field of dishwashers, and in particular to a rapidly expandable central spray structure. Background Technology

[0002] Dishwashers are kitchen helpers for homes and businesses, automatically washing dishes, chopsticks, plates, dishes, knives, forks, and other tableware to help people reduce their housework burden.

[0003] Small-capacity countertop dishwashers also have a place in the dishwasher market. Because they wash fewer dishes, one rack can hold three to four place settings. They also only have one or two spray arms at the bottom. In particular, countertop dishwashers with flip-top or hinged doors are often designed with only bottom spray arms due to space constraints.

[0004] Chinese Patent Publication No. CN211381186U, published on September 1, 2020, discloses a countertop dishwasher, comprising: a shell containing an inner tub, with a spray arm at the bottom of the inner tub; the shell having a through hole; and a water tank housed within the shell, with a cap on the water inlet corresponding to the through hole, and the water outlet connected to the spray arm. The drawback of this patent is that the dishwasher only uses one spray arm at the bottom to spray and wash the dishes in the inner tub, resulting in low washing efficiency.

[0005] In conclusion, there is a need for a countertop dishwasher structure that can improve washing efficiency through multi-directional spraying. Utility Model Content

[0006] This invention aims to overcome the shortcomings of existing small-capacity countertop dishwashers, which often only have a bottom spray arm due to space constraints, resulting in low washing efficiency. It provides a rapidly expandable center spray structure that can improve washing efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rapidly expandable center spray structure includes a dishwasher inner tub and a top cover, the inner tub and the top cover being snap-fitted together. A bottom spray arm is installed at the bottom of the inner tub, and a bottom spray head is installed on the bottom spray arm. A center spray pipe is also fixed to the inner tub, with a center spray head installed at one end of the center spray pipe, the center spray head being placed on the inner side wall of the inner tub. The other end of the center spray pipe is connected to an external water channel. A top spray pipe is fixed to the top cover, with a top spray head installed at one end of the top spray pipe, the top spray head being placed on the inner top surface of the top cover. The wall of the center spray pipe is provided with... An adjusting block groove is provided, and a water channel adjusting block is provided inside the adjusting block groove. The water channel adjusting block and the adjusting block groove are slidably connected. The water channel adjusting block is provided with a central spray water passage hole that matches the inner pipe opening of the central spray pipe. One end of the water channel adjusting block is connected to the bottom surface of the adjusting block groove by a spring. The other end of the water channel adjusting block is located outside the adjusting block groove and is opposite to the other end of the top spray pipe. A top spray water passage hole is provided between the end face of the other end of the water channel adjusting block and the side wall of the central spray water passage hole. The port of the other end of the top spray pipe is opposite to the top spray water passage hole.

[0009] This application adds an expandable central spray pipe and a top spray pipe. The central nozzle on the central spray pipe and the top nozzle on the top spray pipe provide auxiliary water spraying, which can clean locally heavily soiled tableware in the inner tank, completing the washing process more efficiently and improving washing efficiency. The flow of water through the central and top spray pipes is controlled by a water flow regulating block at the regulating block's groove: When the top cover is closed, the top spray pipe on the top cover engages with the water flow regulating block at the regulating block's groove, simultaneously pushing the water flow regulating block until the central spray water inlet and the inner opening of the central spray pipe are concentric. At this point, the water flow is open, allowing water from the external path to flow sequentially to the central nozzle on the central spray pipe and the top nozzle on the top spray pipe, causing both nozzles to spray water simultaneously. When the top cover is open, the top spray pipe on the top cover separates from the water flow regulating block at the regulating block's groove. The water flow regulating block is then automatically lifted by the spring force, causing the central spray water inlet on the regulating block to automatically align with the inner opening of the central spray pipe, thus blocking the water in the central spray pipe. At this point, the water flow is closed, preventing water from the external path from flowing out through the central spray pipe. The structure is simple and easy to control.

[0010] Preferably, a suction cup is fixed to the inner top surface of the top cover, and the top spray pipe is L-shaped. One side of the top spray pipe is adsorbed and fixed to the suction cup. A top spray pipe slot is provided on the inner side wall of the top cover, and the other side of the top spray pipe is snapped and fixed to the top spray pipe slot. The connection method is simple and easy to operate, facilitating installation and disassembly, and reducing the difficulty of later maintenance and repair.

[0011] Preferably, the outer edge of the other end of the water channel regulating block is provided with an outer chamfer, and the inner port of the other end of the top spray pipe is provided with an inner chamfer that matches the outer chamfer. The combination of the outer and inner chamfers improves the smoothness of the connection between the other end of the top spray pipe and the other end of the water channel regulating block, making operation simple, convenient, time-saving, and labor-saving.

[0012] Preferably, a sealing ring is provided on the other end of the water channel regulating block, and the water channel regulating block and the top spray pipe are sealed together by the sealing ring. The sealing ring design prevents leakage of washing water, avoiding leakage through the gap between the top spray pipe and the water channel regulating block, thus improving the sealing performance at the connection between the top spray pipe and the water channel regulating block.

[0013] Preferably, the water path regulating block and the regulating block groove are detachably connected. A water sealing plate is provided on the water path regulating block, positioned at the opening of the central spray water passage near the other end of the central spray pipe. This detachable design allows the water path regulating block to be easily removed from the regulating block groove for replacement, enabling convenient replacement of the appropriate water path regulating block according to the number of dishes and washing needs. The structure is simple and easy to control. When only the bottom spray head on the bottom spray arm needs to spray water, a water path regulating block with a water sealing plate can be selected, which can simultaneously seal both the central spray water passage and the top spray water passage.

[0014] Preferably, the water channel regulating block and the regulating block groove are detachably connected. The water channel regulating block is equipped with a second water-sealing plate, which is positioned at the opening of the top spray water passage. This detachable design allows the water channel regulating block to be easily removed from the groove for replacement, enabling convenient replacement of the appropriate water channel regulating block according to the number of dishes and washing needs. The structure is simple and easy to control. When water needs to be sprayed from the bottom spray head on the bottom spray arm and the middle spray head on the middle spray pipe, a water channel regulating block with a second water-sealing plate can be selected. The second water-sealing plate seals the top spray water passage while keeping the middle spray water passage open.

[0015] The beneficial effects of this utility model are: improved washing efficiency; simple structure and convenient water circuit on / off control adjustment; easy installation and disassembly, reducing the difficulty of later maintenance and repair; improved smoothness of connection and connection, making operation simple and convenient, saving time and effort; improved sealing performance; the appropriate water circuit adjustment block can be easily replaced according to the number of tableware and washing needs to adjust the water circuit, with simple structure and convenient control.
