Description

M252893 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is related to an electric water heater, more specifically, it refers to a type of water heater that is installed on the storage bucket of an electric water heater to buffer and absorb the inside of the barrel. Due to the water pulse force structure generated by the water outlet device or the pipeline switch momentarily, it can effectively reduce the shaking of the barrel body, and can also improve the pressure relief structure of the barrel body or pipeline leakage and burst. [Previous technology] Press, please cooperate with the first picture as shown. The conventional electric water heater 10 mainly includes a water storage tank 11 which has a cold water inlet 12 and a hot water outlet 1 3 at the top, and a bottom end. A drain port 14 is installed, and a heating device (not shown) is installed inside the barrel. The hot water outlet 1 3 is generally connected to various water outlet devices such as a faucet through a water delivery pipe 15 Therefore, when the cold water flows in from the cold water inlet 12, it can be heated by the heating device, and when the user turns on the hot water outlet device such as a faucet, the hot water stored in the barrel can be removed from the heat. The water outlet 13 is sent to the water outlet device through the water delivery pipeline 15 to provide users with various purposes such as washing and bathing. [New content] However, the structure design of the water storage bucket 11 of the conventional electric water heater 10 is still incomplete. When ordinary users turn on hot water through the water outlet device, the hot water stored in the water storage bucket 11 will It will flow at a comparable water pressure and speed. Therefore, when the user closes the water outlet device, the hot water with high pressure in the water pipeline 15 will be instantly resisted, forming a great back pressure. Via water

Page 5 M252893 IV. Creation instructions (2) Pipeline 1 5 passes back 1 1 The internal water storage state is empty. Therefore, the internal water storage generates gas air and water pulses that mutually irritate parts of the barrel. The inside will cause the barrel body to produce the barrel wall or the conveying force, which will shorten the life. It also has the research of the creator ’s structure and the slow pressure air chamber of the pressure relief of the bucket. Room person. That is, the pressure relief structure of the barrel is caused by the water outlet device to cause the barrel to shake up. The storage barrel acts on the storage barrel 1 1. Under normal circumstances, most of the back pressure will further cause the instantaneous water pulse. , And formed no excess space (in fact) or other pressure-relief structures inside the barrel at an instant; instantaneous pressure; therefore, in addition to the phenomenon of aquatic shaking, the water pipeline was leaked or bursted by the internal storage phase Concerns about the use of damage. In view of this, it is based on the concept of long-term fusion, and the structure is created by using electric hot water and pouring a predetermined pressure-deformed depleted rubber diaphragm into the reservoir to form a compact that can be compressed to provide general storage. When the flushing and suction part is accommodated, the barrel will be regenerated within a short period of time. For the various electric water heaters, a closed gas is set on the water storage tank of the electric water heater. At the same time, the interior of the slow pressure bucket is separated from each other, and the buffer effect is slow The main purpose of the creation of the pressure structure is to provide an electric water heater for storing water. The design of the pressure relief air chamber of the water storage barrel is used to prevent the water pulse caused by the instantaneous back pressure of the water flow in the barrel switch. Phenomenon, it can be used to improve life and safety of use. At that time, it will maintain the back pressure and the inter-pressure will only be available pulses and long mutual excitement. Due to the holding force, the bucket force will be generated, and the top will be slowed down or produced within the period. Not only the bucket water-like bucket body water storage due to a small collection. Pressure department

This creation uses the electric pressure-relief structure 40 when the user opens the bucket 3 0 The internal hot water will be heated by the user when the water outlet device is described. The original flow in the water pipeline 34 is a reverse pressure, and it will act on the water pulse phenomenon at the moment of storage. At this time, there is a slow pressure. Structure 40. Therefore, when the gas space remaining at the top of the body is slower than the rubber diaphragm 41, the rubber diaphragm 41 is gradually deformed moderately (as shown in the fourth figure) due to the rubber property, so that the inside of the barrel body is used. Produced water The water may be generated inside the barrel thus, can effectively reduce the leakage of the tub production line burst or damage the feeling of life, and increased safety in use. Please cooperate with the fifth picture, this creation is mainly connected to the top wall edge of the barrel, at the predetermined position of the inner wall edge of the neck 3 5 1 the outer ring of the lock ring solid 4 3 will be an oak. The water heater 2 0 such as the faucet water outlet 3 2 is closed in the instantaneous hot water bucket 3 0 due to the original water flushing medium, the rubber diaphragm 4 1 is compressed and slowed down, so that the pulse acts on the pulse and phase. Shake the earthquake, so it can be connected as follows: The water from the water storage tank is filled through the water pipe, and the water stored in the instantaneous part is pulsed in the barrel body and then indirectly pressurized with a flexible air chamber 44. Progressive The force is slowly stimulated by mutual force. It can also be extended to form a ring flange 3 5 2 around the other mouth 35 of the pressure reducing structure 40. The rubber diaphragm 41 supports the tightness.
