Definitions

  • the present invention relates to a sanitary device attached to a stool-type toilet, and more particularly, to an improvement for enabling the sanitary device to be easily separated from the toilet.
  • High-grade sanitary equipment of this type typically includes a heated toilet seat, an automatically opening and closing toilet lid, a shower nozzle for washing the human body, a warm air dryer, a deodorizing device, and a room heater.
  • sanitary device is fixed on the upper surface of the back of the commode, typically by bolts.
  • Japanese Utility Model No. 5—49995 states that the sanitary fittings and toilet bowl are connected via hinges so that when the sanitary equipment is tilted around the hinges, Discloses a structure in which the bottom of the toilet and the upper surface of the toilet open separately.
  • Japanese Patent Application Laid-Open No. 1-1955823 discloses that the bottom of the sanitary device and the top surface of the toilet can be tilted in the same manner as described above by devising the structure of the bolt in which the sanitary device is fixed to the toilet Discloses a structure in which and are separated and opened.
  • sanitary equipment will be placed on the floor and on the toilet. At that time, the sanitary device may be released in a tilted or upside down position. Even in such a posture, tanks and pipes in the equipment must be specially sealed to prevent leakage of washing water in the equipment.
  • a typical sanitary device includes an electronic circuit for controlling the operation of the above-described components, and an operation panel for a user to operate the electronic circuit. While the sanitary device is separated from the toilet bowl, cleaned and re-attached to the toilet bowl, the buttons on the control panel are accidentally pressed, for example, by extending the shower nozzle and spraying flush water into the toilet, There is a high possibility that the opening / closing stool may start moving and the sanitary equipment may fall over. Also, if the shower nozzle extends or the toilet lid moves while the sanitary device is separated from the toilet and moved, or during cleaning, it will collide with the toilet or the equipment in the toilet, and the nozzle ⁇ toilet lid drive mechanism May break down.
  • one object of the present invention is to make it easier to separate the sanitary device from the toilet in the sanitary device attached to the toilet.
  • Another object is to enable the sanitary device separated from the toilet bowl to be stably fixed at a certain position in a certain posture.
  • Yet another object of the present invention is to prevent the sanitary device from performing unnecessary operations while the sanitary device is separated from the toilet bowl.
  • the sanitary device of the present invention comprises: a fixing element fixed to a toilet; a main body mounted on the toilet; The fixing element and the main body are connected by an appropriate mechanism.
  • the main body can reciprocate between a normal position and another position while being connected to the fixed element via a connection mechanism.
  • the regular rice bowl is typically the top of the back of the toilet.
  • Another position is, for example, a position shifted forward from the normal position along the upper surface of the toilet, or a position lifted up from the normal position.
  • the connecting mechanism supports the main body so as to maintain the horizontal posture while the main body moves.
  • connection mechanism for example, a flexible wire, a rigid rod, a telescopic arm, a foldable arm, or a jack for lifting the main body can be adopted.
  • the contact surface between the main body and the toilet can be exposed by moving the main body from the usual position to another position, so that it can be easily cleaned.
  • moving the main body it is easy to maintain a horizontal posture so that the main body does not tilt because of the help of the connecting mechanism.
  • a rigid mechanism such as a rod or arm-jack is used as the connecting mechanism, the stability during movement is particularly good.
  • the coupling mechanism should be capable of fixing the main body in a stationary state at the position after the movement.
  • the main body is stably maintained at a fixed position and horizontal position, so cleaning can be performed with ease.
  • the main unit When cleaning is completed, the main unit can be returned to its normal position. In the usual position, it is preferable from the viewpoint of appearance that the fixing element is covered by the main body and concealed from the outside.
  • a sanitary device generally has various functional elements such as a shower nozzle, a heating toilet seat, a blower dryer, and a washing water heater, and an operation panel for driving these functional elements.
  • the sanitary device according to the second aspect of the present invention detects whether or not the main body is mounted at a normal position on the toilet, and when the result of the detection is negative, the function is performed even if the operation panel is operated. Prohibition control is performed so as not to drive the element. As a result, during the work of separating the sanitary equipment from the toilet bowl and during cleaning after separation, extra functional elements may be activated and cause problems. There is no danger of causing.
  • those that move automatically such as a shower nozzle, should be driven to move to a predetermined safe position before the driving is prohibited. This eliminates the risk of the functional element being damaged due to collision of the object with the functional element while moving or cleaning the sanitary device. Furthermore, it is desirable that prohibition control should not be applied to the operation of the operation panel for moving such an automatically moving functional element to a safe position.
  • the prohibition control may be automatically released.
  • the start and completion of the installation work are judged, and for functional elements that take a long time to produce an effect, such as water for washing water, the prohibition is released at the same time as the start of work, and other functional elements are released.

Abstract

Lorsqu'un dispositif sanitaire (22) comportant un siège, une douchette, un sécheur à air et autres accessoires, est séparé de la cuvette (21) pour permettre de le nettoyer (22) ainsi que la cuvette (21), une plaque de base (71) fixée à la cuvette (21) et au dispositif (22) par une paire de fils élastiques les reliant empêche le dispositif (22) de tomber à terre pendant la séparation et le nettoyage. D'habitude le dispositif (22) est monté sur la plaque de base (71) avec un système de verrouillage: dans ce cas, les fils (112) s'enroulent autour de bobines (110). Lors du déverrouillage pour faire avancer le dispositif, les fils se déroulent des bobines (110) et retiennent le dispositif (22) pour l'empêcher de tomber de la cuvette (21). On peut utiliser au lieu des fils (112) une biellette, un bras rétractable ou un bras repliable; on peut également à titre d'alternative se servir d'un cric pour soulever le dispositif (22).
