Abstract

The utility model relates to an automatic circulation heating and heat insulation device for bathtubs. Under the condition that the structure of the existing bathtub is not changed, the automatic circulation heating and heat insulation device can conduct automatic circulation heating and heat insulation to water in a bathtub. The utility model comprises a box body. A water pump, a heating bag, a controller, a water guide pipe and an n-shaped pipe are arranged in the box body, wherein, a water inlet of the water pump is communicated with a water suction pipe, and a water outlet of the water pump is communicated with the water guide pipe and a water inlet of the heating bag. A water outlet of the heating bag is communicated with a water outlet pipe through the n-shaped pipe. The water guide pipe is provided with a sealing pipe cap. The pipe opening point of the water suction pipe is provided with a non-return valve with a filtering mesh cover. The utility model not only saves water and energy, but also is convenient for installing. Baths are comfortable by using the utility model.

Description

The automatic circulating heating insulation device of bathtub

The utility model relates to the automatic circulating heating insulation device of a kind of bathtub.

Using bathtub at present is that hot water is injected bathtub, and the people steeps bathing in hot water, when wanting heating, temperature keeping when bathing water temperature decline midway, has only the hotter water of adding and bleeds off the lower warm water of a part of temperature, and this not only strengthens energy resource consumption, also wastes water.In order to address this problem, a kind of bathtub with automatic circular heating heat insulation function is disclosed in Chinese patent 982322348, this bathtub is realized the water in the bathtub is carried out heating, temperature keeping by automatic circulating heater is set, and makes it have the characteristics of energy-saving and water-saving, Energy and comfort.But the circulating heater that this bathtub is installed need be holed on bathtub and some parts is installed, if install circulating heater additional on original common bathtub in the bathroom, installation workload more greatly and very inconvenient.

The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of bathtub automatic circulating heating insulation device, and it can also can not transform original bathtub to the heat tracing that circulates automatically of the water in the bathtub, has the more convenient characteristics of installing.

The purpose of this utility model is achieved in that water pump (2), heat packs (3), controller (5), aqueduct (6) and " n " shape pipe (8) is housed in casing (1), electrical heating elements (4) is housed in the heat packs, the water inlet of water pump (2) is connected with suction hose (10), pump outlet is connected with the water inlet of aqueduct (6), heat packs (3), and the delivery port of heat packs is connected with outlet pipe (9) through " n " shape pipe (8).Aqueduct (6) extends to outside the casing, and threaded sealing pipe cap (7) is equipped with in the upper end, and the check valve (11) of band filtering screen also is equipped with at the mouth of pipe place of suction hose (10).

According to such scheme, need in aqueduct, inject diversion before using for the first time, under the effect of check valve, diversion can not be flowed out from suction hose but water pump, heat packs and the pipeline that is connected are full of, and water is full of the back with the sealed tube cap closure diversion mouth of pipe.Earlier bath water is injected in the bathtub during use, make height of water level surpass the check valve of suction hose below, connect power supply, set the balneation water temperature, open starting switch then by controller.This moment, temperature sensor detected water temperature, water temperature is if be greater than or equal to design temperature, water pump and heating element heater are not worked, if water temperature is lower than design temperature, water pump and heating element heater can start automatically, and water pump is extracted into the water in the bathtub in the heat packs and heats, and flow into bathtub through outlet pipe then and mix with the water of lower temperature, circulation heating by such makes the water in the whole bathtub be heated to preset temperature.After reaching preset temperature, controller cuts off water pump and heating element heater power supply automatically, and the circulation heating stops, and device enters keeping warm mode.When the water in the bathtub was lower than design temperature once more, water pump and heating element heater started again, were incubated the circulation heating, finished the whole process of automatic circulation heat tracing thus.

The utility model is because the heating that can circulate automatically, do not need during insulation to add hotter water and bleed off the lower warm water of a part of temperature, and original bathtub be need not to transform when installing and using, therefore have energy-saving and water-saving, bath comfort, advantage easy for installation.

Accompanying drawing is the structure chart of an embodiment of the utility model.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

This device comprises a casing (1), water pump (2) is housed in the casing, heat packs (3), controller (5), aqueduct (6) and " n " shape pipe (8), heating (4) is housed in the heat packs (3), be close to and heat is housed on the shell melts disconnected device (13), and have at the top, delivery port, heat packs water inlet and aqueduct (6), the delivery port of water pump (2) is connected, aqueduct extends to outside the casing, threaded sealing pipe cap (7) is equipped with in the upper end, the heat packs delivery port is connected with outlet pipe (9) by " n " shape pipe (8), outlet pipe along the bathtub wall lowering to bath base.Suction hose (10) one ends are connected with water pump (2) water inlet, and the check valve (11) of band screen pack, 2/3rds places of suction hose along the bathtub wall lowering to the bathtub degree of depth are equipped with in other end port.Temperature sensor (12) is installed in filtering screen inside to be not intended to can avoid balneation the time its damage, and temperature sensor melts disconnected device with heat and all is connected with controller, and the output of controller is connected with water pump, heating.
