Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a dishwasher. Background Art

[0002] Currently, dishwashers on the market are divided into two types: those without water tanks and those with water tanks. The first type is without water tanks. The water inlet and drainage of the dishwasher adopt the traditional direct connection with the household water pipes, and the structure is relatively simple. The second type is with a water tank. On the one hand, water is supplied by a built-in clean water tank. On the other hand, a waste water tank is set to recycle washing waste water to avoid wasting water resources. At present, the clean water tank and waste water tank of most dishwashers are installed on the left and right sides of the dishwasher respectively. In addition to increasing the cost of the machine, the setting of the two water tanks also fills up the space on the left and right sides of the dishwasher, which will affect the installation of other functions of the dishwasher. Utility Model Content

[0003] Based on this, it is necessary to provide a dishwasher that utilizes the cooperation of a water inlet assembly and a washing assembly to realize an integrated design of a clean water tank and a waste water tank, thereby saving the installation space of the dishwasher and effectively reducing the energy consumption of the dishwasher.

[0004] A dishwasher comprises: an inner tank for accommodating tableware; a water tank disposed on the outer wall of the inner tank and connected to the inner tank for heat conduction; a washing assembly, the washing assembly being communicated with the inner tank and the water tank respectively, the water tank being used to supply washing water to the washing assembly, and the washing assembly being used to spray washing water onto the tableware in the inner tank; a water inlet assembly, the water inlet assembly being communicated with an external water source and the water tank respectively, and the water inlet assembly being used to transport clean washing water to the water tank; a heating device, the heating device being disposed on the washing assembly and being used to heat washing water; wherein the dishwasher has at least a first mode and a second mode, when in the first mode, the washing assembly sprays high-temperature washing water onto the tableware in the inner tank, and the water tank stores clean washing water for absorbing heat for preheating, and when in the second mode, the high-temperature washing waste water in the inner tank is transported to the water tank through the washing assembly to release heat to dry the tableware in the inner tank.

[0005] The present application provides a dishwasher, which forms a water circulation system by arranging a washing component to connect the inner tank and the water tank respectively. With the cooperation of the water inlet component and the washing component, a single water tank can have two functions of clean water storage and waste water storage, and mutual heat transfer is realized by connecting the water tank and the inner tank. When hot water is used for washing in the inner tank, the water tank can store washing water for heat absorption and supply it to the washing component for use after the heat absorption is completed, thereby reducing the amount of electricity required for heating by reducing the heat absorption temperature difference. When washing is completed, the high-temperature waste water generated by washing can be supplied to the water tank for heat dissipation and transfer the heat to the inner tank, so that in different use modes of the dishwasher, the functions of preheating the clean water in the water tank and releasing heat from the high-temperature waste water in the water tank to dry the dishes can be realized. By adopting the above structure, not only the integrated design of the clean water tank and the waste water tank is realized to reduce the number of parts and save the installation space of the dishwasher, but also the energy consumption of the dishwasher is effectively reduced.

[0006] In one embodiment, the washing component includes a water cup, a water delivery component and a spray arm, the spray arm is arranged in the inner tank, the water delivery component is respectively connected to the water cup, the water tank and the spray arm, the water tank supplies washing water to the water cup through the water delivery component, the heating device is arranged on the water cup or the water delivery component, the water cup is provided with a first liquid passing end, when in the first mode, the washing water in the water cup enters the spray arm through the first liquid passing end and the water delivery component and is sprayed onto the tableware in the inner tank through the spray hole of the spray arm; when in the second mode, the high-temperature washing waste water in the inner tank is transported to the water tank through the water delivery component to release heat to dry the tableware in the inner tank. By adopting the above structure, firstly, before the initial washing, the water cup can obtain clean washing water from the water tank for use by the spray arm; when the first mode is executed, the washing water in the water cup will be heated by the heating device and sucked out by the water delivery component to the spray arm for hot water washing. Since the washing water is heated, the temperature of the inner tank of the dishwasher is higher than the temperature of the water tank. At this time, the clean washing water in the water tank is in a heat absorption stage, and will absorb heat from the inner tank to increase the temperature of the clean water in the water tank, thereby preheating. The preheated clean washing water flows to the water cup through the water delivery component for use, thereby reducing the amount of electricity required for heating by reducing the heat absorption temperature difference; when the second mode is executed, the washing work of the dishwasher is completed, and there is high-temperature washing waste water to be discharged in the inner tank. The high-temperature washing waste water is discharged into the water tank through the water delivery component. At this time, the high-temperature washing waste water in the water tank can release heat and transfer it to the inner tank. The released heat can be used to dry the tableware in the dishwasher to improve the drying effect.

With the cooperation of the water inlet component 4 and the washing component 3, the single water tank 2 can have both the functions of clean water storage and waste water storage, and the mutual heat transfer is realized by connecting the water tank 2 and the inner tank 1. When hot water is used for washing in the inner tank 1, the water tank 2 can store washing water for heat absorption and supply it to the washing component 3 for use after the heat absorption is completed, thereby reducing the amount of electricity required for heating by reducing the heat absorption temperature difference. When washing is completed, the high-temperature waste water generated by washing can be supplied to the water tank 2 for heat dissipation and transfer the heat to the inner tank 1, so that in different use modes of the dishwasher, the functions of preheating the clean water in the water tank 2 and releasing heat and drying the dishes by the high-temperature waste water in the water tank 2 can be realized.
