Embodiment Construction
[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] refer to figure 1 , figure 2 and image 3 With the structure shown, the heat pump bottom shell provided by the present invention includes an air duct 2 with an air suction port 1, and the air duct 2 is formed with a first filter screen installation part 3, wherein the air duct 2 is located at the first filter screen installation part 3- A backflow water inlet 4 is formed on the side air duct wall, and a backflow water outlet 5 is formed on the air duct wall of the air duct 2 on the other side of the first filter installation part 3, and a backflow water outlet 5 is formed on the heat pump bottom shell. The backflow channel 6 through which the inlet 4 ...

The invention relates to the technical field of washing machines, and discloses a heat pump bottom shell and a washing machine. The heat pump bottom shell comprises an air duct with an air suction port, a first filter screen installation part is formed in the air duct, a backflow water inlet is formed in the air duct wall, located on one side of the first filter screen installation part, of the air duct, a backflow water outlet is formed in the air duct wall, located on the other side of the first filter screen installation part, of the air duct, and a backflow channel for communicating the backflow water inlet with the backflow water outlet is arranged on the heat pump bottom shell. In this way, a water inlet system of the washing machine can flush a first filter screen installed on the first filter screen installation part, flushing water on one side of the first filter screen installation part can flow back through the backflow water inlet, the backflow channel and the backflow water outlet, for example, the flushing water flows back to the air suction port and then enters a roller through an air suction pipe, and the flushing water on the other side of the first filter screen installation part can directly flow to the air suction port and then enters the roller through the air suction pipe, so that the flushing water is prevented from being gathered on one side of the firstfilter screen installation part.
Description
[0001] This application is a divisional application of a Chinese patent application with an application date of April 28, 2017, an application number of 201710297127.8, and a titled heat pump bottom case and washing machine. technical field [0002] The invention relates to the technical field of washing machines, in particular to a heat pump bottom case and a washing machine. Background technique [0003] With the improvement of people's quality of life, the popularity of various smart home appliances such as washing machines is getting higher and higher. At the same time, various types of washing machines such as drum washing machines have also appeared. At present, the drying methods of conventional drum-type washing and drying integrated washing machines are divided into heat pump type and condensation type. [0004] Among them, the water inlet system of the conventional drum-type heat pump integrated washing and drying machine is relatively independent, and can only re...
