As shown in conjunction with fig. 1 to 5, the embodiment of the present disclosure provides a washing machine, which includes a tub 10 and a cover 40, the tub 10 including an inner tub and an outer tub, wherein the inner tub defines a washing chamber 101 having a delivery port 102, and the washing chamber 101 is used for accommodating laundry to be washed. The washing chamber 101 has a dispensing opening 102, and the cover 40 is disposed at the dispensing opening 102 of the washing chamber 101.

The washing machine of the utility model can be a drum washing machine or a pulsator washing machine. The pulsator washing machine mainly rotates a washing tub to achieve a cleaning effect by twisting friction between clothes. The drum washing machine is capable of achieving a cleaning effect by enabling clothes and a drum wall to flap mutually through rolling up and down and left and right.

Optionally, as shown in fig. 4 and 5, the washing machine further includes a display panel 20 and a reflective panel 30, the display panel 20 being in communication with the washing chamber 101, the display panel 20 being at least partially of transparent structure to enable a user to view the inside of the washing chamber 101; the reflective panel 30 is located in the washing chamber 101 and corresponds to the display panel 20, and the reflective panel 30 is capable of reflecting the information of the articles in the washing chamber 101 to the display panel 20.

In this embodiment, as shown in fig. 5, when the user approaches the washing machine, the user can observe the laundry condition and the water level condition in the washing chamber 101 through the display panel 20 as shown by the dotted arrow in fig. 5. When the user is far away from the washing machine, as shown by solid arrows in fig. 5, the reflective panel 30 can reflect the laundry and water level conditions in the washing chamber 101 to the display panel 20, and the user can still observe the conditions inside the washing machine. Thus, the observation range of the washing machine can be improved, and meanwhile, the observation flexibility and convenience of the washing machine are improved.

Optionally, the display panel 20 is located above the washing chamber 101, which facilitates the user's observation of the inside of the washing chamber 101.

Alternatively, the display panel 20 is located at a front side of the washing machine, and the display panel 20 is inclined downward in a rear-to-front direction.

In this embodiment, since the washing machine is lower than the user's height, the display panel 20 is inclined downward in the rear-to-front direction, so that the sectional area of the display panel 20 can be increased, thereby increasing the viewing area of the user. In addition, the display panel 20 can more wash chambers 101 facing downwards, so that a user can observe more clothes and water level in the wash chambers 101 conveniently.

Alternatively, as shown in fig. 4, the first angle a of the display panel 20 with respect to the vertical direction ranges from 10 ° to 60 °.

In this embodiment, when the first angle a between the display panel 20 and the vertical direction is smaller than 10 °, the light of the display panel 20 facing the washing chamber 101 below is less, so that the user cannot observe or observe less information about the laundry and water level in the washing chamber 101. When the range of the first included angle a is greater than 60 °, the display panel 20 occupies a larger horizontal dimension, which is not conducive to the cooperation of the display panel 20 and the reflective panel 30, and reduces the overall aesthetic property of the washing machine.

For example, the first included angle a may be 15 °, 30 °, 45 °, 55 °, 60 °, and so on.

Alternatively, the reflective panel 30 is positioned at the rear of the display panel 20, and the reflective panel 30 is inclined upward in a rear-to-front direction.

In the present embodiment, the reflective panel 30 is located at the rear of the display panel 20, and the reflective panel 30 is inclined upward in the rear-to-front direction. The reflective panel 30 is thus able to reflect more laundry information within the washing chamber 101 towards the washing chamber 101. Meanwhile, the reflective panel 30 can correspond to the display panel 20, and can reflect laundry in the washing chamber 101 to the display panel 20.

Alternatively, as shown in fig. 4, the second angle b of the reflective panel 30 with respect to the vertical direction ranges from 10 ° to 60 °.

In this embodiment, when the second included angle b is smaller than 10 °, the area of the reflective panel 30 facing the washing chamber 101 is smaller, so that the range of the washing chamber 101 that the reflective panel 30 can reflect is limited, and thus less information is reflected from the reflective panel 30 to the washing chamber 101 of the display panel 20. When the second included angle b is greater than 60 °, the reflective panel 30 can reflect less light to the display panel 20, and the light reflected to the display panel 20 is less, so as to affect the observation range of the washing machine.

For example, the second included angle b may be 15 °, 30 °, 45 °, 55 °, 60 °, and so on.

Alternatively, the upper end of the display panel 20 is connected to the upper end of the reflective panel 30. This facilitates the reflection of the light reflected by the reflective panel 30 to the display panel 20 completely, thereby improving the comprehensiveness and reflection range of the reflection.

Alternatively, as shown in fig. 4, the third included angle c between the display panel 20 and the reflective panel 30 ranges from 60 ° to 120 °.

In this embodiment, when the third included angle c is smaller than 60 °, the third included angle c between the display panel 20 and the reflective panel 30 is not good for the reflective panel 30 to reflect more information in the washing chamber 101 to the display panel 20. When the third included angle c is greater than 120 °, the light reflected by the reflective panel 30 is emitted from the display panel 20, and then the light extends downward, which easily results in a situation that a user on the front side or the upper side of the washing machine cannot observe the inside of the washing machine.

The third angle c may be 60 °, 90 °, 100 °, 120 °.

Optionally, the lower end surface of the reflective panel 30 is located above the washing chamber 101 to avoid the space of the washing chamber 101.

In this embodiment, the lower end surface of the reflective panel 30 does not extend into the washing chamber 101, so that the space of the washing chamber 101 is not occupied, thereby ensuring the volume of the washing chamber 101.

Optionally, the washing machine further includes a connection plate connected between a lower end of the reflective panel 30 and a rear wall surface of the washing machine to support the reflective panel 30.

In this embodiment, the upper end of the reflective panel 30 is connected to the display panel 20, the lower end of the reflective panel 30 is connected to a connection plate, and the connection plate is connected to the rear wall of the washing machine, thus achieving the fixation of the reflective panel 30.
