Problems solved by technology

[0007] However, in the structure of the water level detection part in the above-mentioned conventional drum type washing machine, when the washing water in the water tank 3 is drained through the drain path 7, the washing water flows toward the air trap 100, so foreign objects such as lint tend to enter the air trap 100.
If the thread end enters the air trap 100, an error sometimes occurs between the set water level of the water tank 3 and the actual water level.

Embodiment approach

[0023] figure 1 It is a longitudinal cross-sectional view which shows the drum-type washing machine in embodiment of this invention.

[0024] like figure 1 As shown, a swingable water tub 42 is arranged inside the washing machine casing 41 , and a rotatable rotary drum 43 is arranged in the water tub 42 . A rotation shaft (rotation center shaft) 44 arranged in the horizontal direction is provided at the rotation center of the rotary drum 43 . A motor 45 attached to the vicinity of the back side of the water tank 42 is connected to the rotating shaft 44 via a belt 46 . The rotational driving force of the electric motor 45 is transmitted to the rotating shaft 44 via the belt 46, and the rotating drum 43 is driven to rotate in the forward rotation and the reverse rotation direction. A plurality of protruding plates 47 (lifting ribs) for stirring the laundry (clothing) are provided on the inner wall surface of the rotary drum 43 . In addition, a plurality of water passage ho...

Abstract

An air trap (74) is formed integrally with a water tank (42) in the side wall at the bottom rear of the outer circumference of the water tank (42) and has an opening (88) at the bottom. A water level detection tube (87) communicating with the air trap (74) via the opening (88) is formed integrally at one end of a drainage pipe (64) which is connected to a drainage port (85) formed at the bottom of the water tank (42). The drainage pipe (64) is connected to a case connection port (89) of a filter case (83), and by arranging the air trap (74), the water level detection tube (87), the drainage port (85), the drainage pipe (64), and the case connection port (89) essentially horizontally, the drainage flow is rectified, foreign objects such as pieces of thread contained in the wash water are less prone to flow into the air trap (74), and the water level in the water tank (42) is stabilized.

Description

technical field [0001] The present invention relates to a drum-type washing machine for washing laundry accommodated in a rotary drum. Background technique [0002] Conventionally, such a drum-type washing machine has a water level detection structure for detecting the water level in the water tank (for example, refer to Patent Document 1). [0003] image 3 It is a longitudinal cross-sectional view showing the structure of a main part of the conventional drum-type washing machine described in Patent Document 1, Figure 4 It is sectional drawing which shows the water level detection part of this front-loading-type washing machine. [0004] like image 3 As shown, in the conventional drum type washing machine, a water tub 3 is supported in the drum type washing machine 2 by a suspension structure, and a bottomed cylindrical rotary drum 5 is rotatably arranged in the water tub 3 . A drain path 7 for draining the washing water in the water tub 3 is arranged at the bottom of t...
