Abstract
Description
- The present invention relates to the field of household appliance technologies, to a clothes processing machine, such as a washing machine, a clothes dryer, and a washing and drying machine, and in particular, to a composition and a structure of a control panel component of a clothes processing machine.
- A user sometimes may place a washing machine, a clothes dryer, or a washing and drying machine in a washroom. Large amounts of water vapor is generated during a shower. Electronic members that are exposed to such a high humidity environment for a long time are at risk of a failure. In addition, water vapor is likely to be condensed on an inner side of a display window, resulting in a failure of a touch function. When a machine is running, a specific amount of water vapor and fluff are generated, and the water vapor and fluff are attached to the electronic members and may also result in a failure. Based on development of digitalization, big data and the Internet of Things, intelligent household appliances are certainly a future development trend. Therefore, an electronic member of higher importance, such as a control module of a smart home, may be added to a control panel of a clothes processing machine. An existing control panel is not designed with an effective dustproof and waterproof structure for electronic members. This may affect stability of a product.
- An objective of the present invention is to alleviate the defects existing in the prior art. The present invention provides a control panel component of a clothes processing machine, including a panel body and an electronic member mounted on a back of the panel body, where a protection cover is fixedly mounted on the panel body, and the electronic member is accommodated between the panel body and the protection cover, where a first seal member is disposed between the protection cover and the panel body. Due to a sealing effect of the protection cover, the electronic member is not affected by water vapor and foreign matters in the air and has more stable performance.
- A specific implementation includes that the electronic member includes a circuit board, the circuit board is provided with a circuit port, an opening is provided at a location on the protection cover corresponding to the circuit port, a second seal member is disposed on an edge of the opening, and the second seal member is pressed tightly on a circuit board around the protection cover and the circuit port. In this way, the protection cover does not affect use of the circuit port, and in addition, other parts of the electronic member are still protected by the protection cover from water and dust.
- A specific implementation includes that the protection cover is made of plastic, and a ventilation slot running through the panel body is provided in an area of the panel body covered by the protection cover.
- When the machine runs a drying program or the electronic member overheats, an entire confined space is affected. Because under the same conditions, a water content of the plastic is higher than a water content of the air. During drying or severe overheating of an internal electronic member, a temperature in a space confined by the protection cover rises, and relative humidity of the air inside the space decreases, but a maximum allowable water content thereof increases. In this case, the protection cover and the circuit board both release a specific amount of water vapor to balance the original relative humidity, resulting in that absolute humidity of the air inside the confined space increases, and water vapor pressure increases. The ventilation slot is provided in the panel body, so that the increased water vapor inside the confined space may be discharged through the ventilation slot, to balance pressure inside and outside the confined space.
- A total cross-sectional area of the ventilation slot may be set between 0.8 square millimeters and 1 square millimeter. Since the cross-sectional area for ventilation is extremely small, external water vapor is unlikely to enter into the confined space inside the protection cover.
In some specific implementations, the panel body is provided with a mounting hole that receives a shaft of a knob that extends into the mounting hole, and the ventilation slot is provided in a side wall of the mounting hole and communicates a space between the panel body and the protection cover with an external space. The ventilation slot is disposed in such a way that it is covered by the knob, is unlikely to be clogged with dirt, and also does not affect an appearance of the panel. - The control panel component includes a light guide member disposed on the back of the panel body, where an elastic member may be disposed at a location on the protection cover corresponding to the light guide member, and the elastic member presses the light guide member upward to fix the light guide member to the panel body. The elastic member may be a rubber member. In this way, the light guide member may be fixed by using the protection cover without disposing a fixing means for fixing the light guide member, such as a buckle, on the panel body, thereby simplifying a structure of the panel body.
- Several clamping means that extend away from the panel body may be disposed on the protection cover, to connect the control panel component to a body of the clothes processing machine. Such a design greatly simplifies a design of the panel body. A mold structure of the panel body may be simpler, injection molding cycles of parts thereof may be shorter, molding processes may be more stable, and costs of the parts may also be reduced.
- In a specific embodiment, a first seal member is disposed along an edge of the protection cover as a closed loop.
- The embodiments above may be arbitrarily combined.
- The present invention further provides a clothes processing machine, including the control panel components according to any combination of the foregoing embodiments.
- The clothes processing machine may include a washing machine, a clothes dryer, or a washing and drying machine.
- The following describes the specific implementations of the present invention with reference to the accompanying drawings.
