Abstract

The utility model relates to a vacuum pipe solar water heater, which is mainly composed of a main water tank, a subsidiary water tank, a float ball valve, vacuum pipes, a water supplementing element, etc. The vacuum pipe solar water heater is characterized in that the float ball valve with a delay function is arranged in a water inlet of the subsidiary water tank. The water supplementing element is fixedly arranged on the subsidiary water tank. A cross pipe is arranged in the main water tank. Branch pipes are respectively inserted into the vacuum pipes. Because the float ball valve has the function of delay opening, hot water in the water tank can not be mixed rapidly in the precondition of automatic water supplement. Because the water supplementing element is arranged, the vacuum pipes can be washed by the water supplementing element. Pipe wall scaling can be prevented. Thereby, solar heat collecting efficiency can be enhanced.

Description

A kind of solar vacuum-tube water heater

The utility model relates to a kind of solar vacuum-tube water heater.

Relevant by retrieval patent documentation, not retrieving the employing vacuum tube identical with the utility model structure as yet at present is the solar water heater of heat collector.Existing solar water heater kind is more, differ from one another, the solar water heater that generally has the automatic water supplement function, all be to take major and minor two water tanks to connect, and in secondary water tank, settle a water inlet ball-cock assembly, after water level drops to certain position, open valve automatically, carry out moisturizing, thereby reach the purpose of moisturizing.This type of solar vacuum-tube water heater also because the hot water in its vacuum tube can only carry out heat transmission by the water in the vacuum tube mouth of pipe and the water tank, reaches the water in the heating water tank, so influenced the transmission of heat.And because water temperature is higher in the vacuum tube, the long-term back of using easily produces incrustation scale; So influenced the Heat-collecting effect of vacuum tube.

The purpose of this utility model is to provide a kind of supplementing water with secondary water tank to send into each thermal-collecting tube respectively by water-supply-pipe, has the heat transfer efficiency height, less scaling a kind of solar vacuum-tube water heater.

Technical characterictic of the present utility model is: considering to carry out moisturizing effectively, avoid on the basis of the quick cooling of vacuum tube, be designed to by main water box, secondary water tank, ball-cock assembly, vacuum tube, reflector, support, a kind of solar vacuum-tube water heater that the moisturizing parts are formed, secondary water tank is arranged on the top of main water box, secondary water tank is connected with water inlet pipe, main water box is packed on the support, the delivery port of main water box is connected with outlet pipe, reflector is packed on the support, it is characterized in that: on the water inlet of secondary water tank, be provided with ball-cock assembly, on secondary water tank, be provided with the moisturizing parts that connect with it, described moisturizing parts are by vertical tube, transverse tube, arm, support is formed, the upper end of vertical tube connects with secondary water tank and is connected, the lower end of vertical tube is connected with transverse tube, and transverse tube is arranged in the main water box, and an end of arm is connected with transverse tube, the other end is inserted in the vacuum tube, and is positioned in the vacuum tube by the support support.

Described ball-cock assembly is the valve with delayed start-up function.

During use, when the hot water in the described water heater begins to emit, hot water water level in the main water box is toward descending, wait to arrive certain water level after, and when delaying time to the time that sets, floating asks valve to start working, cold water enters secondary water tank by water inlet pipe, and flow to transverse tube along vertical tube, and adds to the bottom of vacuum tube through each arm, in the process of moisturizing, constantly the hot water in original vacuum tube is entered in the main water box, it is fully used.Because it is body that described vertical tube, transverse tube, arm adopt slim pipe, in the process that cold water flows into, water in original main water box and the vacuum tube is constantly heating it, make the supplementing water that flow into vacuum tube bottom be unlikely to original vacuum tube in hot water the too big temperature difference takes place.

The utility model has the advantages that: owing to be provided with ball-cock assembly in the secondary water tank, and described ball-cock assembly has the function of delayed start-up, thereby can be under the prerequisite of automatic water supplement, is unlikely to make hot water in the water tank to mix very soon and influences result of use; Owing to be provided with the moisturizing parts, thereby each water that replenishes at first entered in the vacuum tube, and vacuum tube is washed away, avoided tube wall incrustation, thereby improved the thermal-arrest and the heat transference efficiency of solar energy; Owing to vertical tube, transverse tube, arm in the moisturizing parts, all adopt the thin-walled material of good heat conduction effect to make, additional cold water can be heated up as early as possible, thereby make the cold water of mend in the vacuum tube be unlikely to original vacuum tube in the hot water excessive temperature differentials, avoided vacuum tube the explosion phenomenon to take place because of its variation of temperature; Because simple in structure, be easy to processing, compare with existing vacuum pipe solar, only need fringe cost seldom, can improve its thermal efficiency greatly, so very big practical and popularizing value is arranged.

Below with reference to description of drawings embodiment of the present utility model:

Accompanying drawing is the structural representation of a kind of solar vacuum-tube water heater of the utility model;

With reference to accompanying drawing, above main water box 1, be provided with secondary water tank 2, main water box 1 is packed on the support 6, and the delivery port of main water box 1 is connected with outlet pipe, and reflector 5 is packed on the support 6.On the water inlet of secondary water tank 2, be provided with a ball-cock assembly 3, the valve of described ball-cock assembly 3 for having the delayed start-up function.Be fixed with moisturizing parts 7 in the bottom of secondary water tank 2, moisturizing parts 7 are made up of vertical tube 8, transverse tube 9, arm 10, support 11, the upper end of vertical tube 8 connects with secondary water tank 2 and is connected, the lower end of vertical tube 8 is connected with transverse tube 9, transverse tube 9 is placed in the main water box 1, and arm 10 is connected with transverse tube 9, and supports to be positioned in the vacuum tube 4 by support 11, it is that material is made that vertical tube 8, transverse tube 9, arm 10 can adopt thin-wall aluminium pipe, plastic tube, stainless steel tube, and present embodiment is selected thin-wall aluminium pipe for use.
