Description

Swimming pool heater

Technical field

The utility model relates to a kind of heater, relates in particular to a kind of Swimming pool heater to the swimming pool heating.

Background technology

For people also can be swum in swimming pool when it is cold, a kind of heated swimming pool has appearred, the swimming pool that a kind of solar energy heating is arranged at present, as an application number is that the Chinese invention patent " solar heating device of swimming pool " of CN200510045310.6 (publication number is CN1776320Y) has disclosed the structure so a kind of, a kind of solar heating device of swimming pool, it comprises solar energy module, the temperature control circulating pump that is connected with the solar energy module pipe, described solar energy module, circulating pump and swimming pool are cascaded by pipeline, constitute circulation line, be provided with check valve in the described circulation line.Simple to operate, and energy-conservation, can make full use of the green energy resource of occurring in nature.This swimming pool has the advantage of environmental protection and energy saving, but its structure more complicated, the manufacturing cost height, and lacking in the date of sunlight, it is bad that it adds thermal effect.

At above-mentioned present situation, occurred a kind of simple in structure on the market, the heater that cost is low, as an application number is that the Chinese invention patent " bathtub thermostat " of CN200420046802.8 (publication number is CN2722114Y) has disclosed the structure so a kind of, a kind of bathtub thermostat, this bathtub thermostat comprises and has, the body of water inlet and water stream channel, body is L-shaped, be fixedly mounted on silicon nitride ceramics heating and the housing that covers on this external surface on the body, the silicon nitride ceramics heating is positioned at the water stream channel of body, it has part to stretch out body surface and be electrically connected with radiator valve, described radiator valve is fixedly mounted on this external surface, and it comprises in order to the device for detecting water pressure that triggers microswitch and detects water temperature and come the temp control switch of control circuit break-make; This thermostat is safe in utilization, volume is little, manufacturing is easy for installation, can be widely used in the water circulation heating of bathtub, large-scale aquarium or swimming pool.Though adopt the security of silicon nitride ceramics heating better, but silicon nitride ceramics heating intensity is higher, cost is also higher, so the silicon nitride ceramics heating is difficult for the type of being bent into, it generally is a vertical bar shaped, and heating surface area is less, also have the body of above-mentioned patent suitable L-shaped, L-shaped body is not suitable for the above-mentioned thermostat of multistage coupled together being strip, and promptly heating power is little, so it is not suitable for using on large-scale swimming pool.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of effective and simple and reasonable Swimming pool heater that heats at above-mentioned prior art present situation, and this heater is particularly suitable for using on swimming pool.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Swimming pool heater, include shell with flowing water passage, shell is provided with water inlet and delivery port, be provided with heating tube in the shell, it is characterized in that described heating tube takes the shape of the letter U, be horizontally installed in the flowing water passage of shell, two free ends of heating tube all upwards pass shell after the bending, to form two links that link to each other with thermostatically-controlled equipment.

Above-mentioned shell is the pipe that is the I font, and water inlet and delivery port are arranged on the two ends of pipe, and has the installation portion that stretches out in the form of a ring at the two ends of pipe, and these two installation portions are parallel to each other.The installation portion of a plurality of these heaters can be tightly connected together successively like this, to form a strip water-supply-pipe, the landline that not only can extend also can make the water that flows into swimming pool fully be heated.

Above-mentioned shell is one to be the three-way pipe of T font, and a water inlet and two delivery ports are arranged, and one of them water inlet and a delivery port are horizontally disposed with, and have the installation portion that stretches out in the form of a ring at the two ends of pipe level, and these two installation portions are parallel to each other.Can guarantee that so not only the water that flows into swimming pool is fully heated, and it also can there be a plurality of delivery ports simultaneously to the swimming pool water filling, the raising water-injection efficiency.

In order to increase the heating surface area of heating tube, two free ends of above-mentioned heating tube all inwardly upwards pass shell after the bending downwards again.The water heating surface area that flows through shell upper reaches aquaporin so just increases, and has further improved to add thermal effect.

For the ease of shell being fixed on attemperating unit or other adjunct, be welded with connecting bolt on the above-mentioned upper surface of outer cover.Only need in the time of fixedly to have corresponding hole on attemperating unit or other adjunct, bolt is passed above-mentioned hole again, get final product with nut is fixing at attemperating unit or other appendicular back side, convenient fixing is quick.

For making in limited bulk, increase the heating surface of heating tube as far as possible, the link of above-mentioned heating tube passes from the U-shaped mouth inside of heating tube.

Compared with prior art, advantage of the present utility model is: heating tube takes the shape of the letter U, it is horizontally installed on heating tube in the flowing water passage of shell, circuitous by two free-ended bendings of heating tube, promptly can in limited space, arrange the heating surface area maximization of heating tube, so increased the thermal effect that adds of heating tube greatly, and the pliability of heating tube is good, can arbitrarily bend, it is convenient to manufacture, heating tube also is a routine techniques, thus the relative advantages of simple of the structure of this heater, and can a plurality of above-mentioned heater series connection use.
