Definitions

  • the invention relates to a water closet seat which comprises a material with low heat transmission coefficient and the surface of which gives a warm feeling when contacted by the users, and to the production method for said water closet seat.
  • the water closet seats produced with the materials having high heat transmission coefficient rapidly transmit the body heat of the user onto the surface of the water closet. Therefore, as the body heat is rapidly transmitted onto the surface of the water closet when the users touch these water closet seats, they feel the cold in their body. Especially during the winter months, this feeling of cold disturbs the users much more. For these reasons, the feeling of cold in the water closet seats is one of the most complained issues in the user surveys.
  • Several solutions have been produced for eliminating this problem in the present state of the art. Use of systems with electric resistance is one of these solutions.
  • the publication no. JP2013066595 (A), titled “Warm toilet seat” can be given as an example to the present state of the art.
  • the invention given as an example contains a toilet seat having a seating surface and a transparent seat heater disposed on the seating surface. In said invention, with the use of a heater apparatus on the seating surface, the user gets a warm feeling from the toilet seating surface.
  • JP2004216076 (A), titled “Human body heating apparatus” can be given as an example to the present state of the art.
  • a warm feeling is provided for the user by sending hot air to the buttocks and waist of said user using the toilet seat.
  • a hot air generating device and ports providing hot air transmission are provided.
  • an electrical connection is required for the operation of the invention given as an example.
  • the invention given as an example is totally different from the invention according to the application.
  • the publication no. TR 2007/03325, titled "Bidet water and toilet seat heating system” can be given as an example to present the state of the art.
  • the current central heating system is utilized for heating the toilet seat and the water flowing through the bidet nozzle of the flush toilet and it is aimed to heat the bidet water and the toilet seat by connecting the coils to the system.
  • the invention given as an example in order to provide heating of the toilet seat a method different from the invention according to the application is utilized.
  • the invention given as an example is disadvantageous because central heating system is required to be installed in the area where the toilet is present. For these reasons, the invention according to the application is different from the invention given as an example.
  • the water closet seats are produced by using materials with low heat transmission coefficient and therefore, body heat of the user is slowly transmitted onto the surface of the water closet seat when contacting with the water closet seat, and it is ensured that the user gets a warm feeling from the surface.
  • materials with low heat transmission coefficient transmit the heat slowly
  • body heat of the users are transmitted from the water closet seat to the surface of the water closet very slowly.
  • users get a warm feeling from the surface of the water closet.
  • the object of the invention is to develop a production method of water closet seat with the use of materials having low heat transmission coefficient, which eliminates the feeling of cold on the water closet seats disturbing the users and a water closet seat which is produced with this method, has a low heat transmission property, and gives a warm feeling to the users when the surface thereof is contacted.

  • the invention relates to a water closet seat which comprises a material with low heat transmission coefficient and the surface of which gives a warm feeling when contacted by the users, and to the production method for said water closet seat.
  • aerogels are the materials with low heat transmission coefficient
  • the use of aerogel is preferred as a material having low heat transmission property in the structure of the water closet seats.
  • the use of resorcinol formaldehyde aerogels is preferred but the use of a different aerogel is also possible.
  • Resorcinol formaldehyde aerogels used are synthetized with sol-gel method. For the synthesis, first resorcinol formaldehyde, catalyst and water are mixed in appropriate amounts. In order to increase strength of the wet gel obtained after the ongoing reactions ageing process is performed. During this process, curing is realized with appropriate solvents at certain temperatures.
  • Resorcinol formaldehyde aerogels are synthesized using sol-gel method.
  • the preparation of RFA can be divided into four main steps; Polymerization, Aging, Solvent Exchange and Drying.
  • the aim of the first part of the synthesis is to prepare the resorcinol formaldehyde gel.
  • First resorcinol is dissolved in an appropriate solvent which is commonly water; however organic compounds such as methanol, ethanol or acetone can also be used.
  • Resorcinol is a phenolic tri-functional compound, which is capable of adding formaldehyde in its aromatic ring. In order to activate the aromatic ring of resorcinol, a catalyst usage is required.
  • a basic catalyst sodium carbonate (Na 2 C0 3 ) is used.
  • Na 2 C0 3 sodium carbonate
  • resorcinol and Na 2 C03 are mixed in water medium, resorcinol is deprotonated as shown in Figure 1. With the deprotonation resorcinol becomes reactive towards formaldehyde. Once the formaldehyde is added in to the mixture, a reaction occurs and it leads to the formation of hydroxyl methyl derivatives (-CH 2 OH) in the ring.
  • the base catalyst further cause the deprotonation of the hydroxyl methylated resorcinol and it leads to very reactive intermediate.
  • the concentration of the reactants and the amount of solvent used during the synthesis has an effect on the structure of the RFA.
  • 1:2 molar ratio of resorcinol and formaldehyde is used in the reaction based on the stoichiometry of the reaction which is shown in the figure 1. Using excess formaldehyde would lead to occurrence of a dilution effect which causes the particle size to increase.
  • the gels are obtained, their pores are filled with water since the water is used as the reaction medium.
  • the liquid in the pores of the gel must be removed without causing the collapse of the pores. This could be achieved by a process called supercritical drying.
  • Most commonly carbon dioxide is used for supercritical drying. Since the solubility of water is very low in supercritical carbon dioxide, the water in the pores of RF gel is replaced by a liquid which has a high solubility in supercritical C0 2 . This step is called solvent exchange step and water is usually replaced with acetone.
  • supercritical drying is performed to replace the acetone in the pores with air. At the end of the supercritical drying process, resorcinol formaldehyde aerogel is obtained.
  • Obtained aerogel is added into the surface of the water closet seat in the form of powder or granule with the method developed within the scope of the invention in the production line of water closet seats.
  • urea formaldehyde granules are added to the lowermost section of the press mold used for the production of the water closet seats, namely to the section of the water closet seat which will contact with the user, in the form of ultrathin layers.
  • powder or granular aerogel is added onto this layer as the second layer.
  • urea formaldehyde granule is added onto this layer as the third layer and forming is performed.
  • urea formaldehyde granules are transferred from inside the silo into a plastic container at an amount to form an ultrathin layer by automatic dosing system.
  • HF high frequency preheating machine
  • Urea formaldehyde granules taken from the preheating process are transferred to the press mold. Pressing process is performed by applying 200 bars pressure between 200-240 seconds to this mold according to the product form. During this process, the mold temperature is kept between 140-150°C.
  • Aerogel granule or powder to be added into the press mold comprising urea formaldehyde as the second layer is transferred from inside the silo into a plastic container at required amount by dosing system and it is kept in a high frequency preheating machine (HF) at a temperature about 40-60°C for 40-60 seconds for the preheating process.
