As shown inFigs. 1 to 4 , thedishwasher 100 according to embodiments of the present disclosure includes a body 1, a heat exchanger 2, afirst fan 3 configured to convey cooling air to the heat exchanger 2, a heater 4, and a second fan 5 configured to convey hot air in anaccommodation cavity 11 to the heat exchanger 2. - The body 1 defines the
accommodating cavity 11 therein, and a wall of theaccommodating cavity 11 defines anair inlet 111 and anair outlet 112. The heat exchanger 2 has ahot air inlet 21, ahot air outlet 22, acooling air inlet 23 and acooling air outlet 24. Thehot air inlet 21 is in communication with theair outlet 112, thecooling air inlet 23 is in communication with external environment, and at least one of thehot air outlet 22 and thecooling air outlet 24 is in communication with the external environment. - An
inlet 43 of the heater 4 is in communication with at least one of thehot air outlet 22 and thecooling air outlet 24, and anoutlet 44 of the heater 4 is in communication with theair inlet 111. Thefirst fan 3 can be configured to convey the cooling air to the heat exchanger 2, and the second fan 5 is configured to convey the hot air in theaccommodation cavity 11 to the heat exchanger 2. The second fan 5 can be located between theair outlet 112 and thehot air inlet 21, or between thehot air outlet 22 and theair inlet 111. - A present dishwasher heats up an accommodating cavity of a body during a drying process, and tableware in the accommodating cavity is dried by the heat in the accommodating cavity. However, the heat in the accommodating cavity may be lost through a wall of the accommodating cavity, such that only part of the heat is transferred to the tableware in the accommodating cavity. Moreover, when a fan is started to reduce humidity in the accommodating cavity, the temperature of the accommodating cavity will be lowered, and the heat in the accommodating cavity will flow out of the accommodating cavity along with an airstream produced by the fan. Thus, the present dishwasher has defects of low heating efficiency and high energy consumption.
- Since the
air outlet 112 of theaccommodating cavity 11 is in communication with thehot air inlet 21 of the heat exchanger 2, the hot air in theaccommodating cavity 11 enters the heat exchanger 2 through theair outlet 112 and thehot air inlet 21 sequentially when the second fan 5 is started. Thefirst fan 3 conveys cooling air from the external environment to the heat exchanger 2 through thecooling air inlet 23 of the heat exchanger 2. The cooling air from the external environment conducts heat exchange, in the heat exchanger 2, with the hot air from theaccommodating cavity 11, such that the hot air from theaccommodating cavity 11 is condensed to lower humidity of the hot air from theaccommodati ng cavity 11, thereby taking away moisture on the tableware. - Meanwhile, the cooling air from the external environment is heated by the hot air form the accommodati ng
cavity 11. T hat is, part of the heat of the hot air from theaccommodati ng cavity 11 is transferred to the cooling air from the external environment. In other words, the part of heat leaving theaccommodating cavity 11 along with the hot air remains in the cooling air, and the rest heat remains in the hot air. - Since the
inlet 43 of the heater 4 is in communi cati on with the at least one of thehot air outlet 22 and thecooling air outlet 24, the part of heat leaving theaccommodating cavity 11 enters the heater 4 and hence returns to theaccommodating cavity 11. That is, the part of heat leaving theaccommodating cavity 11 is not lost but returns to theaccommodating cavity 11. The heater 4 heats up the air entering the heater 4, and the heated air enters theaccommodati ng cavity 11 to dry the tableware in theaccommodating cavity 11. - By utilizing the hot air to dry the tableware in the
accommodating cavity 11, thedishwasher 100 according to embodiments of the present disclosure may reduce the quantity of heat lost through the wall of theaccommodating cavity 11 considerably, such that more heat is conveyed to the tableware in theaccommodating cavity 11, thereby improving heating efficiency and drying speed of thedishwasher 100, and lowering energy consumption of thedishwasher 100. - In addition, for the
dishwasher 100 according to embodiments of the present disclosure, by communicating the inlet of the heater 4 with the at least one of thehot air outlet 22 and thecooling air outlet 24, the part of heat leaving theaccommodating cavity 11 can return to theaccommodating cavity 11 again, and hence it is possible to prevent the heat in theaccommodating cavity 11 from getting lost along with the airstream produced by the fan, so as to reduce the energy consumption of thedishwasher 100. - Therefore, the
dishwasher 100 according to embodiments of the present disclosure has advantages of high heating efficiency, high drying speed and low energy consumption. - As shown in
Figs. 1 to 4 , thedishwasher 100 according to related examples and embodiments of the present disclosure includes the body 1, the heat exchanger 2, thefirst fan 3, the heater 4 and the second fan 5. - As shown in
Fig. 1 , the body 1 defines theaccommodating cavity 11 therein, and the tableware can be stored in theaccommodating cavity 11. Theair inlet 111 and theair outlet 112 are defined in the wall of the accommodati ngcavity 11. - Advantageously, the
air inlet 111 is located below theair outlet 112. Since the hot air flows from the bottom up, theair inlet 111 is provided below theair outlet 112, thereby facilitating flow of the hot air into the accommodati ngcavity 11. - As shown in
Fig. 1 , the wall of theaccommodating cavity 11 is provided with theair inlet 111 and theair outlet 112. For example, theair inlet 111 can be defined in a peri pheral wall of the accommodati ngcavity 11 and adjacent to a bottom wall of theaccommodating cavity 11; theair outlet 112 can be defined in the peripheral wall of theaccommodating cavity 11 and adjacent to a top wall of theaccommodating cavity 11, so as to facilitate flow of the hot air into the accommodati ngcavity 11.

In such a case, theaccommodating cavity 11, the second fan 5, the heat exchanger 2 and the heater 4 constitute a closed loop, such that the hot air is kept within the closed loop to minimize the heat loss. Thefirst fan 3 and the heat exchanger 2 constitute an open loop. - After the cooling air from the external environment conducts heat exchange with the hot air from the
accommodating cavity 11 in the heat exchanger 2, the cooling air from the external environment returns to the external environment through the coolingair outlet 24, while the hot air from theaccommodating cavity 11 enters the heater 4 through thehot air outlet 22. The hot air from theaccommodating cavity 11 is heated by the heater 4 and then returns to theaccommodating cavity 11.
