Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water flush toilet seat device. 2. Description of the Related Art As is well known, in a hot water flush toilet seat, a control mechanism,
An electromagnetic valve mechanism, a hot water tank and a nozzle are provided, and by the control mechanism, water pressure is supplied into the hot water tank via the electromagnetic valve and the nozzle is displaced inside the toilet, and the water pressure causes the nozzle to move out of the hot water tank. The extruded hot water is jetted from the nozzle. The supply of the water pressure in the hot water tank is performed when an electromagnetic valve interposed between the hot water tank and the water pressure source is opened. [0003] However, as disclosed in Japanese Patent Application Laid-Open No. 2001-87169, for example,
If, for design reasons, the distance between the solenoid valve and the hot water tank is long, in cold weather, when water is pumped from the solenoid valve to the hot water tank, if the water temperature is higher than the ambient temperature, heat radiation will occur, The temperature of the water pumped to the tank drops. As a result, the temperature of the hot water stored in the hot water tank decreases, and the duration of the hot water jetted toward the local part of the user is shortened, causing discomfort to the user. [0004] Therefore, it is a technical object of the present invention to provide a warm water flush toilet seat device in which such a problem is not caused. [0005] Technical means taken to solve the above-mentioned problems include a control mechanism, a solenoid valve, and hot water heated by a heater in a case fixed to the upper rear part of the toilet. A hot water tank and a nozzle for storing the hot water are provided, and the amount of electricity supplied to the heater is controlled by the control mechanism so that the temperature of the hot water is maintained at a predetermined value. When supplied, the nozzle is displaced inside the toilet bowl, and in the hot water flush toilet seat device in which hot water pushed out of the hot water tank by the water pressure is jetted from the nozzle, the electromagnetic valve and the hot water tank In the control mechanism receives heat from the substrate and other heating elements of the control mechanism. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a hot water flush toilet seat device according to the present invention will be described with reference to FIGS. [0007] The hot water flush toilet seat device 10 includes a case 14 fixed to the rear upper surface of the toilet bowl 12. In the case 14, the first control mechanism 20, the second control mechanism 30, the solenoid valve 4
0, a hot water tank 50 for storing hot water heated by the heater 52 and a nozzle mechanism 60 are provided. A solenoid valve 40 disposed on one side inside the case 14 is connected to a water supply source 70 via a hose 42 and to a hot water tank 50 via a hose 44, respectively. When the electromagnetic valve 40 is opened by the operation of the valve 20, the hot water in the hot water tank 50 is supplied to the anal cleaning nozzle 62 (bidet cleaning nozzle 64) through the switching valve 66, and the anal cleaning nozzle 62 (bidet cleaning). The nozzle 64) extends into the toilet bowl 12, and the warm water is jetted from the anal cleaning nozzle 62 (bidet cleaning nozzle 64) to clean the user's anus (bidet), as is well known. Which nozzle is supplied with hot water depends on the operating position of the switching valve 66. The hot water tank 50 is arranged on the other side inside the case 12. The water in the hot water tank 50 is supplied to the heater 52.
Is heated. The water temperature is constantly detected by the temperature sensor 54, and the temperature is sent to the CPU 32 of the second control mechanism 30 as a signal. When the water temperature reaches a predetermined value, the CPU 32 controls the energization of the heater 22 from the power supply 90 by interrupting the triac 34, and always maintains the water temperature at the predetermined value. The CPU 32, the triac 34, and the other electronic elements 36 of the second control mechanism 30 are fixed on a substrate 38 housed in a substrate case 80. Triac 3
The radiator plate 82 for bridging the electronic device 4 and the other electronic element 36 has a U-shaped cross section. At the U-shaped portion, the radiator plate 82 extends from one side to the other side inside the case 12 and is A hose 44 connecting the tank 50 is clamped. Thus, the triac 34, the CPU 32, and the other electronic element 36 generate heat of 60 degrees and 40 degrees Celsius, respectively, and this heat is radiated to the water supplied into the hot water tank 50. Thus, since the water pumped into the hot water tank 50 is not cold water but is raised to a predetermined temperature, if the temperature of the hot water discharged from the hot water tank 50 and jetted from the nozzles 62 (64) decreases quickly, No discomfort to the user. In addition, since the cold water passes through the hose 44, the fear of dew condensation caused by the temperature difference between the inside and outside can be wiped out, and the adverse effects on the electronic elements caused by the dew can be prevented. The operation of the solenoid valve 40 and the switching valve 66 and the temperature control of the toilet seat 92 are performed by the first controller 20. If this substrate (not shown) is adjacent to the hose 44, The heat may be radiated to the hose 44. Although the embodiment of the present invention has been described above, the present invention is not intended to be limited to the above-described embodiment, and any warm water flush toilet seat device that conforms to the gist of the present invention can be used. Such a thing may be used. According to the first aspect of the present invention, since the water fed to the hot water tank is absorbed while passing through the hose, the cold water is fed to the hot water tank. The resulting duration of the hot water injected from the nozzle is not reduced and does not cause discomfort to the user. Further, since the water passing through the hose is heated, dew condensation on the hose can be prevented, and adverse effects on the electronic elements due to the dew can be reliably prevented.
