detailed description

Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A dishwasher 100 in accordance with an embodiment of the present invention will now be described with reference to Figs. As shown in FIGS. 1 to 4, a dishwasher 100 according to an embodiment of the present invention includes a body 1, a heat exchanger 2, a first fan 3 for conveying cooling air to the heat exchanger 2, a heater 4, and the like. The hot air in the accommodating chamber 11 is delivered to the second fan 5 of the heat exchanger 2.

The body 1 has a receiving chamber 11 in which an air inlet 111 and an air outlet 112 are provided. The heat exchanger 2 has a hot air inlet 21, a hot air outlet 22, a cooling air inlet 23, and a cooling air outlet 24. The hot air inlet 21 is in communication with the air outlet 112, the cooling air inlet 23 is in communication with the outside environment, and at least one of the hot air outlet 22 and the cooling air outlet 24 is in communication with the outside environment.

The inlet 43 of the heater 4 is in communication with at least one of the hot air outlet 22 and the cooling air outlet 24, and the outlet 44 of the heater 4 is in communication with the air inlet 111. The first fan 3 can be used to deliver cooling air to the heat exchanger 2, and the second fan 5 is used to deliver hot air within the accommodating chamber 11 to the heat exchanger 2. The second fan 5 may be located between the air outlet 112 and the hot air inlet 21 or between the hot air outlet 22 and the air inlet 111.

The existing dishwasher heats the accommodating cavity of the body in the drying stage, and the tableware in the accommodating cavity is dried by the heat in the accommodating cavity. However, heat in the accommodating chamber is lost through the wall of the accommodating chamber, resulting in only a portion of the heat transferred to the dishes in the accommodating chamber. Moreover, when the fan is turned on to lower the humidity in the accommodating chamber, the temperature of the accommodating chamber is lowered, and the heat in the accommodating chamber flows out of the accommodating chamber with the flow of the fan. Therefore, the existing dishwasher has the drawbacks of low heating efficiency and high energy consumption.

Since the air outlet 112 of the accommodating chamber 11 communicates with the hot air inlet 21 of the heat exchanger 2, when the second fan 5 is turned on, the hot air in the accommodating chamber 11 sequentially enters the heat exchange through the air outlet 112 and the hot air inlet 21. Inside the device 2. The first fan 3 delivers cooling air from the outside environment from the cooling air inlet 23 of the heat exchanger 2 to the heat exchanger 2. The cooling air from the external environment exchanges heat with the hot air from the accommodating chamber 11 in the heat exchanger 2 to condense the hot air from the accommodating chamber 11 to lower the humidity of the hot air from the accommodating chamber 11, so that it can be taken away Moisture from the tableware.

At the same time, the cooling air from the external environment is heated by the hot air from the accommodating chamber 11. That is, a part of the heat in the hot air from the accommodating chamber 11 is transferred to the cooling air from the outside environment. In other words, with hot air A portion of the heat leaving the accommodating chamber 11 remains in the cooling air and the remainder remains in the hot air.

Since the inlet 43 of the heater 4 communicates with at least one of the hot air outlet 22 and the cooling air outlet 24, a part of the heat leaving the accommodating chamber 11 enters the heater 4 and returns to the accommodating chamber 11. That is, a part of the heat leaving the accommodating chamber 11 is not lost, but is returned to the accommodating chamber 11. The heater 4 heats the air that has entered the heater 4, and the heated air enters the accommodating chamber 11 to dry the dishes in the accommodating chamber 11.

The dishwasher 100 according to the embodiment of the present invention can greatly reduce the amount of heat that is lost through the wall of the accommodating chamber 11 by drying the dishes in the accommodating chamber 11 by using hot air, whereby more heat can be transferred to the accommodating chamber 11 The tableware inside is used to increase the heating efficiency and drying speed of the dishwasher 100, and to reduce the energy consumption of the dishwasher 100.

Moreover, the dishwasher 100 according to an embodiment of the present invention can make a part of the heat leaving the accommodating chamber 11 come back by bringing the inlet of the heater 4 into communication with at least one of the hot air outlet 22 and the cooling air outlet 24. The inside of the accommodating chamber 11 can thereby prevent the heat in the accommodating chamber 11 from being lost with the airflow of the fan, so as to reduce the energy consumption of the dishwasher 100.
