Description
[0001] CASING STRUCTURE
[0002] Subject of the Invention
[0003] The invention relates to a casing structure, which enables the components in a circuit board, said circuit board having at least one antenna that transmits signals and / or receives signals in at least one radio frequency, to be protected from the external factors.
[0004] State of the Art
[0005] As a result of today's technological development and accessibility of the technology, the electronic circuit boards used in the industry and in the devices for daily use, notably in the electronic home appliances, are now often used in the Internet of Things (loT) electronic devices, including peripherals and / or sensors, which are able to connect to a web and communicate with each other or with other remote access devices. The products with said connectivity features, which the users may remotely access and use via their mobile phones, computers, and / or home assistants, have similarly become common in the toilet rooms / bathrooms for public use or in the toilet rooms / bathrooms for personal use. In order to provide the devices, especially the devices mentioned above, with the feature of connectivity to said electronic products, the RF hardware modules, which perform the radio-frequency (RF) broadcasts according to the known methods, are used.
[0006] The mentioned electronic devices may be present in wet / moist environments and may even be directly connected to the plumbing. Besides, it is necessary to perform the electric connections of said devices so that they can perform their functions. Although it is possible to install the power lines in the environments like toilet rooms / bathrooms in a manner appropriate for installation in a wet area pursuant to the standards set by the regulatory bodies, it is necessary to ensure that the electronic devices are free of nonconformities that could originate from the user and / or that could directly affect the safe use of said electronic devices. For this reason, it is a must to take the measures for ensuring the liquid- and / or dust-proofing in these products in line with the standards set by the regulatory bodies.In said electronic devices, most of these safety measures are taken in respect of the components that are disposed inside said devices and are in a direct or indirect contact with the water. RF hardware modules are among the components, for which it is essential to ensure the liquid- and / or dust-proofing.
[0007] The liquid- and / or dust-proofing for the RF hardware modules should be considered in a manner different than the known methods. In case the proofing is not applied correctly, the damages likely to occur in the antenna, which is located on the component and which enables the RF broadcast, may result in the connection problems for the user and / or in the undesirable conditions that directly affect the use or the accessibility of the device.
[0008] Likewise, in case the liquid- and / or dust-proofing application is to be performed on the RF hardware in the form of a coating or a filling made with a chemical, it is required to search the correct material and select the specific coating chemicals. These chemicals may be procured under special conditions and involve special application rules, which bring about the requirement for investment in high-cost manufacturing devices, time, and labor.
[0009] Similarly, for the applications of liquid- and / or dust-proofing performed on the RF hardware in the form of coatings or fillings, which are made with chemicals, the requirement to test the thickness of the coating or the filling in the finalization of the process as well as to test the RF broadcast performance of the RF hardware of the finished electronic device subsequent to the process of coating or filling also require investment in high-cost testing devices, time, and labor.
[0010] In case the applications of liquid- and / or dust-proofing performed on the RF hardware in the form of coatings or fillings, which are made with chemicals, are not correct and the correctness of said applications is not tested, the nonconformities that would directly affect the safety of the product and of the user may occur when said RF hardware contacts a liquid in a wet area where it is installed.
[0011] Similarly, in case the applications of liquid- and / or dust-proofing performed on the RF hardware in the form of coatings or fillings, which are made with chemicals, are not correct and the correctness of said applications is not tested, the operation of said RF hardwarewith low performance may result, which in turn may cause the device connection problems on the part of the user and the undesirable conditions directly affecting the use or accessibility of the device.
[0012] The electronic devices according to the state of the art involve a different positioning approach, whereby the antenna is relocated to a point distant from the water, and thus, the integrity of the antenna and the board is disrupted in the RF hardware. However, the relocation of the antenna complicates the design of the electronic device in terms of electromagnetic interference, reflection coefficient, and impedance matching, due to the need to perform extra design work on the product.
[0013] Likewise, in case of the application of liquid- or dust-proofing being performed in a way other than the use of coatings or fillings, which are made with chemicals, it is necessary to perform special designs and to work with special boxing materials in order to ensure that the RF broadcast is not affected. This complicates the design of the device and increases the cost of the product.
[0014] Another solution includes performing the coating or filling processes for the liquid- or dustproofing with the chemicals that would not influence the RF broadcast. This approach makes it necessary to work with chemicals with different properties for each hardware performingthe RF broadcast and to implement different application rules foreach of these. This complicates the manufacturing steps of the device and increases the cost of said device.
[0015] Similarly, it is necessary to test the RF broadcast performance of the RF hardware in order to ensure that said coating or filling processes with chemicals are performed with correct thickness and with correct rules of application, which bring about the requirement for investment in high-cost testing devices, time, and labor.
[0016] Object of the Invention
[0017] An object of the invention is to propose a casing structure, which enables the applications of coating or filling with chemicals to be performed for the purpose of liquid- and / or dust-proofing, without disrupting the RF broadcast performance, integrity, or the antenna structure for the household products present especially in the wet areas, said household products having the feature of connectivity and providing this feature externally by means of a hardware independent of said product.
[0018] Another object of the invention is to provide the liquid- and / or dust-proofing by means of the casing box according to the invention disposed on an electronic device, without disrupting the integrity of the antenna and the board in the RF hardware used in said electronic devices and without relocating said antenna to a point distant from the water.
[0019] Another object of the invention is to ensure that the coating or filling processes with chemicals for the purpose of liquid- or dust-proofing are performed only for the electronic part, in which the electronic components are present, and thus, to develop a casing structure that would provide advantages in terms of time and cost directly in the manufacturing processes.
[0020] Another object of the invention is to enable the applied chemical to be exempt from the rules concerning the thickness of the chemical and the rules concerning the specific application, owing to the fact that said applied chemical has no direct interaction with the antenna and the RF broadcast.
[0021] Still another object of the invention is to develop a casing structure, which enables the coating or filling processes with chemicals for the purpose of liquid- or dust-proofing to be applied without requiring a special-purpose chemical that has no impact on the RF broadcast.
[0022] Still another object of the invention is to develop a casing structure, which enables the formation of a receptacle-shaped guide for the chemical liquids applied during the coating or filling processes with chemicals for the purpose of liquid- or dust-proofing.
