[0002] The cleaning performance of a spray-type dishwasher is primarily determined by factors such as wash temperature, detergent dosage, spray flow rate, and spray pressure. Existing dishwashers use a wash pump to pump wash water for spray cleaning. The spray pressure and flow rate during the wash process are both generated by the wash pump. When higher spray pressure and flow rate are required, this is typically achieved by increasing the wash pump's outlet pressure. This involves replacing the wash pump with one with higher outlet pressure and flow, which increases energy consumption and costs. Summary of the Invention

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 3 As shown, the present invention provides a dishwasher, comprising: a washing pump 1; a spray structure (not shown in the figure), the spray structure is connected to the washing pump 1; an energy storage structure 2, the energy storage structure 2 has an energy storage state connected to the washing pump 1 and a pressurized state connected to the spray structure. In the energy storage state, the washing pump 1 supplies water to the energy storage structure 2, and in the pressurized state, the washing pump 1 and the energy storage structure 2 both supply water to the spray structure. By setting the energy storage structure 2 to store the water output of the washing pump 1, the energy storage structure 2 and the washing pump 1 can supply water at the same time when spray washing is performed, so that the water inlet flow rate and water inlet volume at the spray structure are increased, thereby doubling the jet flow rate and flow rate of the spray structure, enhancing the cleaning effect, and the energy storage structure 2 can also switch between the energy storage state and the pressurized state to achieve pulse washing, enhance the impact effect, enhance the ability to remove stubborn stains, and optimize the cleaning effect.

[0028] Specifically, the dishwasher also includes a water cup, and the washing water is collected in the water cup. When the dishwasher is working, the energy storage structure 2 switches to the energy storage state, and the washing pump 1 pumps the washing water out of the water cup and sends it to the energy storage structure 2 for storage. As the washing water gradually enters the energy storage structure 2, the water volume and pressure in the energy storage structure 2 gradually increase, and the pressure in the energy storage structure 2 can be the same as the water outlet pressure of the washing pump 1. Then, washing is carried out, and the energy storage structure 2 switches to the pressurized state. The washing water pumped out by the washing pump 1 and the washing water stored in the energy storage structure 2 are simultaneously attacked to the spray structure for spraying, so that the water volume and flow rate at the spray structure are both twice that when the washing pump 1 is supplied alone. According to the momentum theorem and the kinetic energy theorem, it can be seen that the jet flow rate of the spray structure can be increased by two times, the momentum is increased by two times, and the kinetic energy is increased by four times, effectively enhancing the washing effect. The washing water after washing falls back into the water cup under the action of gravity for circulation.

[0029] Specifically, the water cup is also provided with a water inlet pipe and a drain pipe. The water inlet pipe is connected to an external water source to supply water into the water cup, and the drain pipe can drain the water in the water cup.

[0030] In one embodiment, the dishwasher further includes a water diversion mechanism 3, with the energy storage structure 2 communicating with the water diversion mechanism 3. In the energy storage state, the energy storage structure 2 communicates with the washing pump 1 via the water diversion mechanism 3, and in the pressurized state, the energy storage structure 2 communicates with the spray structure via the water diversion mechanism 3. The water diversion mechanism 3 can divert water from the washing pump 1 to the energy storage structure 2 or directly supply it to the spray structure, as needed. It can also select the energy storage structure 2 for water storage or water supply, as needed. This allows the energy storage structure 2 to switch between the energy storage state and the pressurized state.

[0031] In one embodiment, Figure 1 As shown, the water distribution mechanism 3 has a first connecting port 31, a second connecting port 32 and a third connecting port 33. The first connecting port 31 is connected to the washing pump 1, the second connecting port 32 is connected to the spray structure, and the third connecting port 33 is connected to the energy storage structure 2. In the energy storage state, the first connecting port 31 is connected to the third connecting port 33. In the pressurized state, the first connecting port 31 and the second connecting port 32 are both connected to the third connecting port 33.

[0032] In one embodiment, the energy storage structure 2 includes a tank body 21, which is connected to the water diversion mechanism 3. The interior of the tank body 21 can store the washing water sent by the water diversion mechanism 3. As the washing water enters, the water volume in the tank body 21 gradually increases, and the gas inside is gradually compressed, so that the pressure in the tank body 21 eventually becomes the same as the water outlet pressure of the washing pump 1. Therefore, when the energy storage structure 2 is in a pressurized state, it can synchronously supply water with the washing pump 1, and does not cause part of the water outlet of the washing pump 1 to flow back into the energy storage structure 2, thereby reducing the washing effect.

[0033] Optional, such as Figure 1 As shown, the tube body 21 is connected to the third communication port 33 through the communication pipe 4 .

[0034] Since washing water is stored in the tank body 21, when the dishwasher is draining, the pressure inside and outside the tank body 21 changes, which will cause the tank body 21 to drain poorly, causing water to be trapped in the dishwasher. To this end, the energy storage structure 2 also includes a back-pressure structure, which is provided on the tank body 21 and can connect the tank body 21 with the outside of the tank body 21. The back-pressure structure connects the inside and outside of the tank body 21, allowing the gas outside the tank body 21 to enter the inside of the tank body 21, thereby facilitating the outflow of water inside the tank body 21 and avoiding the occurrence of water trapping.

[0035] Specifically, the back pressure structure includes a movable plunger 22 (see Figure 2 and Figure 3), the tank body 21 is provided with an air vent, and the movable plunger 22 is movably provided in the tank body 21, and the movable plunger 22 can block the air vent. When the energy storage structure 2 is in the energy storage state or the pressurized state, due to the pressure inside the tank body 21, the movable plunger 22 can be squeezed toward the air vent, so that the movable plunger 22 blocks the air vent. At this time, the inside of the tank body 21 and the outside of the tank body 21 cannot be connected through the air vent, ensuring that the pressure inside the tank body 21 can be generated to meet the use requirements. When the dishwasher is draining, the amount of water inside the tank body 21 gradually decreases, and the pressure also gradually decreases. The squeezing force on the movable plunger 22 is reduced, thereby opening the air vent. The inside of the tank body 21 and the outside of the tank body 21 are connected through the air vent, and the water in the tank body 21 can be smoothly discharged from the water storage tank.

[0036] As another embodiment, the energy storage structure 2 further includes a limit cover 23, a groove is provided on the tank body 21, the limit cover 23 is provided at the opening of the groove, the groove is provided with a first air vent 24, and the limit cover 23 is provided with a second air vent 25 (see Figure 2 and Figure 3 ), the back pressure structure includes a movable plunger 22, which is disposed in the groove. The movable plunger 22 can control the communication state between the first air vent 24 and the groove and / or the communication state between the second air vent 25. In other words, the movable plunger 22 is disposed outside the tank body 21, and the first air vent 24 and the second air vent 25 are provided to achieve communication between the interior of the tank body 21 and the exterior of the tank body 21. When the energy storage structure 2 is in the energy storage state or the pressurized state, due to the pressure inside the tank body 21, the gas in the tank body 21 can enter the groove and squeeze the movable plunger 22 toward the second air vent 25, so that the movable plunger 22 blocks the second air vent 25. At this time, the interior of the tank body 21 and the outside of the tank body 21 cannot be connected through the first air vent 24 and the second air vent 25, ensuring that pressure can be generated inside the tank body 21 to meet the use requirements. When the dishwasher is draining, the amount of water inside the tank body 21 gradually decreases, and the pressure also gradually decreases. The squeezing force on the movable plunger 22 is reduced, thereby opening the second air vent 25. The interior of the tank body 21 and the outside of the tank body 21 are connected through the first air vent 24 and the second air vent 25, and the water in the tank body 21 can be smoothly discharged from the water storage tank.

[0037] In another embodiment, the back-pressure structure includes an air pump connected to the tank 21. When the dishwasher is draining, the air pump supplies air to the tank 21, squeezing out the water inside, similarly preventing water trapping. The air pump also provides pressure to the energy storage structure 2 in both the energy storage and pressurized states, further increasing the spray pressure at the spray structure and improving the washing effect.

[0038] As another embodiment, the volume of the tank body 21 can be variable. The volume of the tank body 21 can change as the pressure inside the tank body 21 changes, thereby ensuring that the drainage pressure of the tank body 21 is always the same. When the water pump assembly is draining, the volume of the tank body 21 gradually decreases as the internal pressure decreases, squeezing out the water in the tank body 21 and avoiding the occurrence of water trapping.

[0039] In one embodiment, the spray structure includes at least one spray arm, and in a pressurized state, the energy storage structure 2 is connected to the at least one spray arm, and the connection is selected based on actual needs or preset conditions.

[0040] Specifically, the spray structure includes an upper spray arm and a lower spray arm. In a pressurized state, the energy storage structure 2 can be connected to the upper spray arm and / or the lower spray arm.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
