Abstract

Provided are a detergent compartment and a laundry processing device. The detergent compartment includes a first receiving cavity. The top of the first receiving cavity is provided with a water inlet. A water inlet assembly is disposed at the water inlet and configured to pressurize a water flow passing through the water inlet and direct the water flow onto the sidewall of the first receiving cavity.

Claims (33)

1 . A detergent compartment, comprising:

a first receiving cavity, wherein a top of the first receiving cavity is provided with at least one water inlet, and

a water inlet assembly disposed at a water inlet among the at least one water inlet, the water inlet assembly configured to pressurize a water flow passing through the water inlet and to direct the water flow onto a sidewall of the first receiving cavity;

wherein the water inlet assembly comprises:

an inlet pipe disposed in the first receiving cavity, wherein a first end of the inlet pipe is connected to the water inlet; and

a pressurizing plate configured to receive the water flow from the inlet pipe, wherein a first end of the pressurizing plate is connected to a second end of the inlet pipe, a second end of the pressurizing plate is inclined towards a bottom of the first receiving cavity and extends towards the sidewall of the first receiving cavity, and a first long flow channel is formed between the pressurizing plate and the sidewall of the first receiving cavity.

2 . The detergent compartment of claim 1 , wherein the pressurizing plate is L-shaped, a riser plate of the pressurizing plate is connected to the inlet pipe, an arc notch extending downwards and towards a cross plate of the pressurizing plate is disposed on the riser plate of the pressurizing plate, and a slope inclined downwards is disposed on an upper surface of the cross plate of the pressurizing plate.

3 . The detergent compartment of claim 1 , wherein the water inlet assembly further comprises a water blocking member, the water blocking member is connected to the pressurizing plate, and the water blocking member is configured to block the water flow from flowing away from the sidewall of the first receiving cavity.

4 . The detergent compartment of claim 3 , wherein the water blocking member is an L-shaped plate and is disposed on a side of the pressurizing plate facing away from the sidewall of the first receiving cavity, a riser plate of the water blocking member is connected to the first end of the pressurizing plate, and a cross plate of the water blocking member is connected to the second end of the pressurizing plate.

5 . The detergent compartment of claim 1 , further comprising:

a compartment body; and

a main component connected to the compartment body, wherein the main component and the compartment body form the first receiving cavity, and the at least one water inlet is disposed on the main component.

6 . The detergent compartment of claim 5 , wherein a first flow channel is disposed around the first receiving cavity and on the main component, and the at least one water inlet is disposed in the first flow channel.

7 . A detergent compartment, comprising:

a first receiving cavity, wherein a top of the first receiving cavity is provided with at least one water inlet, and

a water inlet assembly disposed at a water inlet among the at least one water inlet, the water inlet assembly configured to pressurize a water flow passing through the water inlet and to direct the water flow onto a sidewall of the first receiving cavity;

wherein the water inlet assembly comprises a guide plate disposed along a circumferential direction of the water inlet and extending into the first receiving cavity, a guide surface inclined towards a bottom of the first receiving cavity and extending towards the sidewall of the first receiving cavity is provided at a part of the guide plate facing the sidewall of the first receiving cavity, and a second long flow channel is formed between the guide surface and a part of the guide plate facing the guide surface.

8 . The detergent compartment of claim 7 , wherein a water blocking protrusion is disposed on a side of the water inlet facing the guide plate.

9 . A laundry processing device, comprising:

a drum and a detergent compartment, wherein the detergent compartment comprises a first receiving cavity, a top of the first receiving cavity is provided with at least one water inlet, and

a water inlet assembly disposed at a water inlet among the at least one water inlet, the water inlet assembly configured to pressurize a water flow passing through the water inlet and to direct the water flow onto a sidewall of the first receiving cavity;

wherein the water inlet assembly comprises:

an inlet pipe disposed in the first receiving cavity, wherein a first end of the inlet pipe is connected to the water inlet; and

a pressurizing plate configured to receive the water flow from the inlet pipe, wherein a first end of the pressurizing plate is connected to a second end of the inlet pipe, a second end of the pressurizing plate is inclined towards a bottom of the first receiving cavity and extends towards the sidewall of the first receiving cavity, and a first long flow channel is formed between the pressurizing plate and the sidewall of the first receiving cavity.

10 . The laundry processing device of claim 9 , wherein the pressurizing plate is L-shaped, a riser plate of the pressurizing plate is connected to the inlet pipe, an arc notch extending downwards and towards a cross plate of the pressurizing plate is disposed on the riser plate of the pressurizing plate, and a slope inclined downwards is disposed on an upper surface of the cross plate of the pressurizing plate.

11 . The laundry processing device of claim 9 , wherein the water inlet assembly further comprises a water blocking member, the water blocking member is connected to the pressurizing plate, and the water blocking member is configured to block the water flow from flowing away from the sidewall of the first receiving cavity.

12 . The laundry processing device of claim 11 , wherein the water blocking member is an L-shaped plate and is disposed on a side of the pressurizing plate facing away from the sidewall of the first receiving cavity, a riser plate of the water blocking member is connected to the first end of the pressurizing plate, and a cross plate of the water blocking member is connected to the second end of the pressurizing plate.

13 . The laundry processing device of claim 9 , wherein the water inlet assembly comprises a guide plate disposed along a circumferential direction of the water inlet and extending into the first receiving cavity, a guide surface inclined towards a bottom of the first receiving cavity and extending towards the sidewall of the first receiving cavity is provided at a part of the guide plate facing the sidewall of the first receiving cavity, and a second long flow channel is formed between the guide surface and a part of the guide plate facing the guide surface.

14 . The laundry processing device of claim 13 , wherein a water blocking protrusion is disposed on a side of the water inlet facing the guide plate.

15 . The laundry processing device of claim 9 , further comprising:
