Description

Improved low-power energy water heater

The utility model relates to a kind of improved low-power energy water heater.

The power of the electric heater of general storage-type electric energy shower or EWH's product, at least need 6000W above could satisfy (meeting) user demand---the heating-up time is shorter, needn't wait the hot water temperature that can reach more than at least 40 ℃ for a long time, use for shower.Because the household electricity in the many areas of China all is only limited to the EWH who is suitable for below the 3000W, for 6000W or above high-power electric energy water heater, the part that can only hang back does not have Fuan dress at all and enjoys; And the small-power storage-type electric energy shower or the EWH that all have to install below the 3000W use, yet, when installing and using this kind small-power storage-type electric energy shower or EWH, its heating-up time is very long, at least need the time of marquis of a specified duration more than tens of minutes, just can reach hot water temperature more than at least 40 ℃ for shower, the use of having a bath, will spend the above time of half an hour at least but whenever have a bath, so make the people feel very consuming time, inconvenient.

At the shortcoming of prior art, the purpose of this utility model is to provide a kind of improved low-power energy water heater, to solve low-power energy water heater long problem heat time heating time.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of improved low-power energy water heater mainly is made of a low-power energy heater, a storage tank, a water spot electric switchgear, a cold water inlet, a suction pump and a hot water outlet pipe; The closed casing of its storage tank for making with the nylon plastic material, establish a shedding motion in the bottom suction pump is arranged, at upside one buzzer device is housed, and there is a hot water inlet pipe to be connected with the low-power energy heater at one side of upside device, simultaneously, install an overflow pipe again at the upside another side of its casing again; It is characterized in that: between above-mentioned cold water inlet and suction pump and hot water outlet pipe, refill and be equipped with an isocon joint, a circulating hot water pipe, an entering water electromagnetic valve and a three-way connection; In about water level position more than 1 liter of storage tank, install an electronic type level control switch for water additional and set up the electronic-controlled installation of control suction pump and a water intaking valve breakdown action.

By the improved low-power energy water heater of the utility model, overcome the shortcoming of prior art, make water temperature heat up very fast and save heat time heating time, reached the purpose of above-mentioned creation.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is a front schematic view of the present utility model.

As shown in Figure 1, the improved low-power energy water heater of the utility model mainly is made up of low-power energy heater 5, one storage tanks, 15, one water spot electric switchgear 2, one cold water inlets, 1, one suction pumps 7 and a hot water outlet pipe 14; This storage tank 15 generally is the sealed casing made from the nylon plastic material, establishes an opening in the bottom with device suction pump 7, at upside one buzzer device 8 is housed, and can send the caution sound when full-water level, informs that shower person can use; And be connected with the low-power energy heater one side of upside device one hot water inlet pipe 10, admit the hot water that heated by this low-power energy heater 5 to flow in its casing; Simultaneously, the upside another side at its casing installs an overflow pipe 9 more again, can overflow the water of overfill naturally; Again, at its casing at least about the water level position more than 1 liter, install an electronic type level control switch for water 6 additional and set up an electronic-controlled installation (figure does not show), when hot water being entered reach these level control switch for water 6 positions in its casing, can open suction pump 7 and water intaking valve 3 automatically, make and heated part hot water in the storage tank 15, after being dispensed out cold water mix that a part sends into cold water inlet 1 and becoming warm water, just deliver to heat on the low-power energy heater 5 and again stream return in the casing of this storage tank 15.This low-power energy heater 5 is the general following low-power energy heater of 3000W, water inlet end is connected with cold water inlet 1, and on the pipeline of this cold water inlet 1 device one water spot electric switchgear 2, hydraulic pressure by water inlet makes it energising and does water heating action to open this low-power energy heater 5.On this hot water outlet pipe's 14 pipeline, device one opens and closes the action whether valve 13 control hot water outputs are used for shower.In addition, the utility model is 14 of cold water inlet 1 and suction pump 7 and hot water outlet pipes, install an isocon joint 17 again, one circulating hot water pipe 11, one entering water electromagnetic valve 3 and a three-way connection 16, and install a warm water intake pipe 4 in addition 5 of this three-way connection 16 and low-power energy heaters and be connected it.

The utility model is when taking a shower, traditional storage-type EWH is the same with manipulating, at first must open the keying valve (figure does not show) on the cold water inlet 1, enter low-power energy heater 5 heating that opened by this water spot electric switchgear 2 after making cold water by water spot electric switchgear 2, just enter in the casing of storage tank 15 and store, when reaching about ninety percent full-water level (be buzzer device 8 send caution the sound), can open the action that takes a shower of keying valve 13 on the hot water outlet pipe 14.Not to be " directly " be stored in cold water water inlet heating in the storage tank 15 the utility model, remakes shower when waiting ninety percent full-water level, the action of having a bath, but at the beginning of the unlatching in the water that low-power energy heater 5 directly heated is stored in storage tank 15 casings; When water level reaches electronic type water level switch 6 positions, can open suction pump 7 and water intaking valve 3 automatically, make the part hot water that had heated in the storage tank 15, pumped out by suction pump 7 again, via isocon 171, little isocon 172 on the isocon joint 17 of 172 (sizes approximately position 2.5 to 1 or 2 to the 1) circulating hot water pipe 11 that flows through, entering water electromagnetic valve 3 and three-way connection 16, enter again in the warm water intake pipe 4 and the cold water mix that newly enters by cold water inlet 1, after making cold water become warm water, just flow into 5 heating of low-power energy heater, to store in the casing that enters storage tank 15 once again; So circulation, the water inlet of heating is the cold water at the beginning of opening, and enters the water of accepting heating in the low-power energy heater 5 later on, is warm water; Therefore, it is several and reduce time of water heat temperature raising to improve the temperature of water heat temperature raising, so the hot water that can enjoy enough heat of need not waiting so long is done shower, the action of having a bath.Hot water in the casing of the utility model storage tank 15 has reached about ninety percent full-water level and has just done shower, when having a bath action, though opened the keying valve 13 on its hot water outlet pipe 14, so that by the hot water in the 171 outflow storage tanks 15 of the large shunt pipe on the isocon joint 17, but still have the hot water of fraction to flow out via 172 shuntings of the little isocon on this isocon joint 17 simultaneously, with flowing into again in the warm water intake pipe 4 according to aforementioned manner and the cold water mix that newly enters by cold water inlet 1, can make equally into water cold water become behind the warm water circulation again heating flow into again in the storage tank 15, so simultaneously shower, the one side of having a bath is replenished hot water, shower is done in the back, the people who has a bath need not wait, can then use and more wash more heat, comparing with traditional low-power energy water heater, really is as far apart as heaven and earth.
