Abstract

The utility model relates to a displacement type domestic water heater, comprising a water heating unit 1, a hot water pipe 7, a hot water box 8, a shower spraying head 9, a buffer unit 11, a water feeding tap 4, a water discharging tap 5, etc. A hot water displacement type structure is used, so that the utility model has the advantages of simple structure, convenient use, flexibly adjustable water flow and temperature, and full utilization of domestic heat sources. The problem of insufficient hot water supply in directly heated water heaters can be overcome.

Description

Displacement type domestic water heater

The utility model belongs to daily living article, and specifically it is a kind of family expenses displaced type hot water shower that is mainly used in the shower bathing.

Household hot water shower is the product that welcome by family, and development was very fast in recent years.Application number is to have introduced a kind of domestic hot water's shower in China's utility application prospectus of 89201241.2, it by one in the shape of a spiral the duplex coil of type be welded with up and down difform heat collecting sheet, be welded in collector mat, heater is outwards drawn and is taken over mouthful difference water pipe and a tap and a shower nozzle UNICOM, and output is controlled by tap.This shower is when less or water consumption is big at the family expenses thermal source, the inaccessible shower requirement of water temperature.

The purpose of this utility model provides a kind of displaced type household hot water shower, to overcome the deficiencies in the prior art.

The purpose of this utility model can reach by following structures.The utility model is made of water heater, hot water line and shower head, main points of the present utility model are that water heater is a cylindricality closed container, side lower part at water heater has a water inlet pipe mouth that connects with valve, at the top of water heater one effluent pipe mouth is arranged, effluent pipe mouth connects with hot-water line, the upper end of hot-water line connects with a boiler, and shower head connects with hot-water line through a control valve.The utility model in use, connect with water tap with the water inlet pipe mouth of a pipe earlier water heater, the valve of opening water inlet pipe mouth then is with topped up with water in the water heater, valve-off also heats it with thermals source such as domestic briquet stoves, when water temperature rises to predetermined temperature, open valve once more and in water heater, add water, and utilize the pressure of running water and the hot water in the water heater is pressed in the boiler that is installed in the higher position, cold water is with hot water displacement finishing back valve-off, continuation adds device to water and heats, at this moment can open the control valve of shower head and carry out shower, when the water temperature in water heater reaches predetermined temperature, just can open valve and be pressed in the boiler.

Breathe heavily the stirring action that stream causes in order to reduce cold water, the utility model can be equipped with a buffer unit in water heater, this buffer unit and water inlet pipe mouth link, buffer unit is to be made of a buffer container and a buffering outlet pipe, the mouth of pipe of the buffering outlet pipe of buffer unit is horn-like, and its mouth of pipe downwards and be positioned at the centre of water heater inner bottom part.Like this, when cold water is injected by water inlet pipe mouth, after the buffer container buffering, be pressed in the water heater via the bottom of buffering outlet pipe again from water heater, because the stirring action when having reduced to be pressed into, make the hot water that is positioned at the upper strata be pressed boiler gradually, thereby reduced the temperature decline scope of hot water in the replacement process.

The utility model also can be equipped with water intaking tap and draining tap in the upper and lower of water heater, so that take the water in hot water and the discharge water heater.

The utility model has been owing to adopted hot water displaced type structure, the utlity model has the flexible modulation water yield simple in structure, easy to use and temperature, makes full use of family's heat sources but make, thereby reached the purpose of this utility model.

Accompanying drawing has provided an embodiment of the present utility model, further specifies concrete structure of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing 1 is a structural representation of the present utility model.Among the figure, 1 is water heater, there are one and valve 2 joining water inlet pipe mouths 3 in its underpart, also be connected with water intaking tap 4 and draining tap 5 on it, one effluent pipe mouth 6 is arranged at its top, and effluent pipe mouth 6 connects with hot-water line 7, and the upper end of hot-water line 7 connects with boiler 8, shower head 9 connects with hot-water line 7 through control valve 10, and a buffer unit 11 that is made of a buffer container 12 and a buffering outlet pipe 13 is installed in water heater 1.

The utility model can make full use of family's compact heat source, has overcome the problem of directly-heated type hot water for quantity not sufficient, has bigger market prospects.
