Description

Control panel chiller of washing machine

The present invention relates to a control panel cooling device of a washing machine, and more particularly, by circulating a part of the washing water toward the control panel during washing to allow the heat generated from the control panel to be cooled, thereby preventing malfunction of the control panel. A control panel cooling device of a washing machine.

In general, a washing machine has a cylindrical water tank 11 installed inside a rectangular main body 10 by a hook rod 10a as shown in FIG. 1, and a washing tank 12 and a pulsator inside the water tank 11. 13) is installed. The pulsator 13 is rotated forward and reverse during washing to cause a rotational flow, the washing is rubbed with each other by the rotational flow. In addition, the washing tank 12 is rotated at a high speed during dehydration and the centrifugal force is applied to the laundry during the high speed rotation to be dehydrated. In addition, a power switching member 15 driven by a motor 14 is installed at the bottom of the water tank 11, and the pulsator 13 and the washing tank 12 are selectively rotated by the power switching member 15. In addition, a control panel 17 for controlling functions such as washing, rinsing and dehydration is installed on the upper plate 16 on the upper portion of the main body 10.

The conventional washing machine configured as described above includes laundry and washing water in the washing tank 12, and then, when the power switching member 15 is rotated forward and backward by driving the motor 14, its rotational force is transmitted to the pulsator 13 to generate rotational water flow. do. At this time, the washing flow is rubbed with each other by the rotating water flow generated, washing proceeds, and the rinsing is simultaneously performed in the washing process. When the washing is completed, the washing water is drained and then dewatered. That is, when the power switching member 15 is rotated at a high speed in one direction by the driving of the motor 14, the washing tub 12 is rotated at a high speed while the internal laundry is dehydrated by centrifugal force.

However, in the conventional washing machine, heat is generated in the control panel 17 that controls the washing or dehydration process, and there is a risk of malfunction due to high heat when washing for a long time. That is, there are components that generate heat in the circuit components (transistor, integrated circuit and microcomputer) constituting the control panel 17, these components are provided with a separate heat radiation fins to naturally dissipate heat in the air. However, if the washing is performed for a long time, the heat dissipation ability of the heat radiation fin is exceeded, and the heat is directly acted on the control panel.

The present invention was developed in view of the conventional problems, and an object of the present invention is to force a part of the wash water to be circulated to the control panel by the centrifugal force of the rotating water during the washing process, so that the heat generated from the control panel is forced to cool water. In particular, to provide a control panel cooling device of a washing machine to improve the heat dissipation ability of the control panel, especially when washing for a long time.

In order to achieve the above object, the present invention is provided with a main body having a water tank in which a pulsator is installed, and a control room in which a control panel is placed on the upper plate of the upper part of the main body. It is provided in a zigzag form and has an inlet through which a washing water is forced to circulate toward the cooling water pipe by a centrifugal force of rotational water generated when the pulsator rotates on one side of the water tank.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic perspective view of the present invention cooling device and Figure 3 is a side cross-sectional view of the present invention cooling device, the same components as in Figure 1 will be described the present invention using the same reference numerals. The control chamber 18 in which the control panel 17 is placed in front of the upper plate 16 covering the upper portion of the main body 10 is provided, and the coolant pipe 20 is provided in a zigzag form at the bottom of the control chamber 18. In addition, an inlet 21 is formed at one side of the lower portion of the water tank 11, and the inlet 21 is connected to the coolant pipe 20 through the hose 23. At this time, the inlet 21 is provided with a guide plate 25 protruding toward the inner circumferential surface of the water tank 11 and the rotational flow impinges on the guide plate 25 is guided toward the inlet 21. In addition, the washing water flowing into the inlet 21 is pumped upward by the hose 23 by centrifugal force and forcedly circulated toward the cooling water pipe 20. In addition, an outlet 22 is formed on the outer circumferential surface of the upper portion of the water tank 11, and the cooling water pipe 20 communicates with the outlet 22 via the hose 24. Therefore, the wash water circulated to the cooling water pipe 20 is recovered along the outlet 22 into the water tank 11.

In the present invention configured as described above, the coolant pipe 20 through which the washing water is circulated is arranged in a zigzag form on the bottom of the control room 18 on which the control panel 17 is placed. In addition, the inlet 21 formed at the bottom of the water tank 11 is connected to the front end of the cooling water pipe 20 and the hose 23, and the outlet 22 formed at the top of the water tank 11 is connected to the rear end of the cooling water pipe 20. The washing water is circulated by connecting to the hose 24, respectively. The present invention is such that when the washing is carried out in the washing tank 12 in the state containing the washing water and the washing water is rubbed with each other while rotating water flow in accordance with the forward and reverse rotation of the pulsator 13 is in progress. In addition, in the washing process, a part of the rotational water collides with the guide plate 25 and flows toward the inlet 21.

At this time, the washing water introduced is forced up to the upper portion by the hose 23 by the centrifugal force and circulated to the cooling water pipe 20. Therefore, the control panel 17 placed directly above the cooling water pipe 20 is water cooled. That is, the control panel 17 generates heat from various circuit components while the washing machine is operating. In this case, if the washing is performed for a long time, the heat dissipation of these parts is lowered, and the heat may affect other parts of the control panel 17, causing a malfunction of the device. At this time, since the wash water is circulated inside the coolant pipe 20 installed at the bottom of the control panel 17, heat generated from the control panel 17 is cooled with water, and heat dissipation is not deteriorated.

As described above, according to the present invention, a cooling water pipe is installed inside the control room in which the control panel is installed, and an inlet through which the washing water flows into the lower part of the water tank is formed. In addition, as the inlet and the cooling water pipe are connected to the hose, part of the washing water is circulated toward the cooling water pipe by the centrifugal force of the rotating water generated by the rotation of the pulsator during the washing process. Therefore, the heat generated from the various circuit components installed in the control panel is forcibly water-cooled, so that there is an effect that the malfunction of the device does not occur when washing for a long time.
