[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a natural heat radiating heat held in a hot water tank as a hot water storage tank in a heat exchanger hot water tank having a cleaning mechanism for discharging hot water to a local human body and a heat exchanger for generating hot water to be supplied to the cleaning mechanism. A sanitary washing device suitable for obtaining the durability of the hot water retention time by disposing a highly airtight air cell in the outer periphery of the tank following the internal pressure deformation of the tank. It relates to a warm water tank thermal insulation structure.
[0002]
[Prior art]
The hot water tank of the sanitary washing apparatus is composed of two upper and lower box-shaped parts formed of a resin material, and is configured as one hot water tank by welding or screwing. In addition, the hot water tank is arranged in the tank for detecting the supply water temperature, and a connecting pipe and a water inlet pipe for connecting and supplying water as a secondary pressure after regulating the supply water from the water supply to a constant pressure with a valve. It has a basic configuration in which a thermistor that controls energization heating to the heater and a vacuum breaker for discharging hot water and releasing negative pressure are provided. In addition, a bimetal-type overheat prevention switch is installed to prevent malfunction of the hot water control device, and a float switch and a thermal fuse are assembled to prevent overheating of the heater, thereby forming a stable hot water holding mechanism configuration.
[0003]
On the other hand, the heat exchanger hot water tank of the sanitary washing device is also a pressure vessel that resists the secondary pressure regulated by the valve. For this reason, it is necessary to provide long-term durability performance against repeated internal pressure loads every time a sanitary washing device is used. In general, reinforcing parts such as reinforcing ribs are disposed on the outer periphery of the tank to ensure long-term durability of the tank.
[0004]
[Problems to be solved by the invention]
Based on the above reasons, the outer periphery of the hot water tank has a large number of projections such as equipment attachments and reinforcements, and the location of the insulation material on the outer periphery of the hot water tank is limited, or the protrusion is the main heat dissipation part. There were many cases. Further, even if the heat insulating material is applied, the gap between the outer peripheral portion of the tank and the heat insulating material becomes a natural heat radiation path by air convection, and an effective heat insulating effect cannot be obtained.
[0005]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a heat exchanger hot water tank that maintains an effective heat retaining effect that eliminates as much as possible a decrease in hot water tank temperature due to natural heat dissipation. There is.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a sanitary washing apparatus comprising a washing mechanism that discharges hot water to a human body part, and a hot water tank that retains and stores warm water supplied to the washing mechanism. A heat insulating material was provided on the outer periphery of the hot water tank, and air was sealed between the hot water tank and the heat insulating material. Therefore, the air having a small thermal conductivity directly serves as a heat insulating material for the heat exchanger hot water tank, and an effective heat insulating effect can be obtained.
[0007]
To achieve the above object, the present invention is a sanitary washing apparatus comprising a washing mechanism that discharges hot water to a human body part, and a hot water tank that retains and stores hot water supplied to the washing mechanism, It was set as the structure where the air enclosed between the warm water tank and the heat insulating material forms the cell divided into several. Therefore, even if a gap is generated between the hot water tank and the heat insulating material, the heat radiating part stays in only some cells, and an effective heat insulating effect can be maintained without deteriorating the heat retaining effect.
[0008]
To achieve the above object, a cleaning mechanism for discharging hot water to the human body part, Te sanitary washing apparatus odor and a hot water tank for storing incubating the hot water supplied to the washing mechanism, the insulation flexible Due to the flexibility of the heat insulating material, the heat insulating material can be synchronized with the deformation caused by the pressure change in the hot water tank while the air is sealed. In this way, even when an internal pressure load is applied to the heat exchanger hot water tank, the heat insulating material follows the deformation of the hot water tank, and effective heat insulation effect without escaping the enclosed air even for the dynamic operation of the tank Can be maintained.
[0009]
In order to achieve the above object, the present invention is a sanitary washing apparatus comprising a washing mechanism that discharges hot water to a human body part, and a hot water tank that retains and stores warm water supplied to the washing mechanism. to encapsulate the air between the hot water tank and the heat insulating material, the outer peripheral portion of the hot water tank and projecting the cell walls of the air enclosed, a plurality of compartments disposed, substantially continuous heat-insulating material at its end A sealing surface was formed . For this reason, the heat insulating material can be produced by simply punching a flat sheet by simple die-cutting, and can be attached to a three-dimensional tank by simply applying an adhesive on one side, and an effective heat insulating effect can be achieved without reducing the heat insulating material productivity. Can be maintained.
