Abstract
The utility model relates to a household water boiling device which belongs to the field of the water heating apparatus. The utility model comprises an inner water tank, wherein, the exterior of the inner water tank is provided with a water sleeve which is communicated with the inner water tank. The water sleeve is provided with a water outlet. The upper part of the inner water tank is provided with an upper water tank which is communicated with the inner water tank. The upper water tank is provided with a water inlet. The bottom of the upper water tank is not smaller than the upper surface of the water sleeve. The space of the inner water tank and the water sleeve is gradually reduced. The bottom of the inner water tank is higher than the bottom of the water sleeve. The inner water tank and the water sleeve are communicated and fixed through three communicating pipes. The utility model has the advantages of simple structure, high heat efficiency and low cost.
Description
The utility model belongs to the hot-water heating system field, particularly a kind of family expenses boiler.
The existing family expenses device that boils water has teapot, electric heater etc., and boiling water is directly hotted plate with pot for cooking rice by some family, and electric heater uses and is subjected to the power supply restriction, with teapot, pot boil water then that the thermal efficiency is lower, during energy charge.
The family expenses boiler that provides a kind of thermal efficiency higher is provided the purpose of this utility model.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of family expenses boiler, comprise inner water tank, and inner water tank has a water jacket that is communicated with it outward, and water jacket is provided with delivery port; One water tank that is communicated with it is arranged at inner water tank top, and the upper water box bottom surface is not less than the water jacket upper surface, and upper water box is provided with water inlet; Inner water tank and water jacket spacing are from bottom to top by subtracting.
The inner water tank bottom surface is higher than the water jacket bottom surface, and is fixing by being communicated with three communicating pipes between inner water tank and water jacket.
The technical scheme that the utility model adopts outside water jacket to cooperate with inner water tank, upper water box, simple in structure, cost is low; The water jacket inwall is frustum, and inner water tank and water jacket spacing reduce gradually, makes that flow velocity slowed down when flue gas flowed from bottom to top, helps flue gas and fully contacts with water tank with water jacket, and the thermal efficiency is higher; The upper water box bottom surface helps heat and makes full use of greater than the water jacket upper surface.
Fig. 1 is the utility model structural representation;
Further specify the utility model below in conjunction with accompanying drawing by embodiment.
Embodiment, a kind of family expenses boiler comprises inner water tank 1 and the water jacket 2 that has delivery port 5, is communicated with fixing by 3 communicating pipes 4 therebetween.The water jacket inwall is frustum, make inner water tank and water jacket spacing from bottom to top by subtracting, that is exhaust gases passes 7 shrinks from top to bottom gradually, help improving the thermal efficiency, there is a upper water box 3 to be communicated with on the inner water tank with it, water inlet 6 is arranged on the upper water box 3, and the upper water box bottom surface is greater than the water jacket upper surface, and the inner water tank bottom surface is higher than the water jacket bottom surface.
During use this boiler is placed on the cooking stove, be filled to and be higher than the upper water box bottom surface, open fire and to use.
