Description

Portable dehumidifier

The application submitted, shows resigned U.S. Patent application, application number NO07/817,940 part continuation application on January 8th, 1992.

The present invention relates generally to air-conditioning equipment, particularly relate to electric dehumidifier.

Conventional dehumidifier is equiped with quite heavy workpiece, as an evaporator coil, a condenser, a compressor and a fan motor.Usually, these parts are installed on the inner support and by one or more outer panels or cover and surround.The functional part, interior support and the shell that design dehumidifier so in the past by this way exist several shortcomings or deficiency, at first, supporting member normally is made of a plurality of metal parts, these parts are assembled and need a large amount of installation times also can be corroded, and conduct electricity, and water can be by the slit between each part.Internal supporting structure lacks globality and causes one or more inner support to be fixed together with an outer cover.When removing outer cover, be attached to the supporting member on the outer cover, and will separate with other internal structure by any parts that supporting member supported, therefore, after outer cover removes, be difficult to make various functional units to do operation or test.Equally, former bearing assembly can not catchment at dehumidifier provides real isolation between parts and the relative high-voltage part, therefore can not reduce the possibility of electricity injury.

In dehumidification process, ice accumulates in evaporimeter and helps on sheet and the coil pipe, and compressor had just stopped work before the air that flows through evaporimeter is blocked by ice basically usually.Be provided with defrost cycle circulation, in allow fan open and compressor cuts out, make warm relatively air flow through evaporimeter with ice-out.In the past, when evaporimeter reach one select low temperature the time, during as 27 °F, defrost cycle begins, and when evaporimeter reaches a selected high temperature, stops during as 37 °F.If at this moment the humidity level of Xi Wanging does not reach yet, compressor must be reworked.As a result, cause, therefore reduced the service life of this critical component at the frequent start-stop of high humidity environment lower compression machine.

The advantage of Portable dehumidifier is its portability, but certain shortcoming or problem are also arranged, and these shortcomings are insignificant to standard-sized dehumidifier.One of sixty-four dollar question is if the Portable dehumidifier water that is placed in the life zone overflows, this zone or other infringement is arranged of will making dirty.The water tank of Portable dehumidifier is than the little of standard size dehumidifier and frequently pour out possibly.Do like this, then the user must remove the full water tank floor of passing by, and carpet and furniture are to sewer, and bathtub or other drainage position go.In the former Portable dehumidifier,, have a very big opening in tank top for admitting the condensed water of evaporator coil; As a result, it is very difficult full water tank being taken off and moves drainage position to and do not sprinkle water out.

To another special problem of being concerned about of Portable dehumidifier is to have expired or the possibility that this device is operated when putting the place not in the position when water tank, and owing to the additional destruction that is caused from this device infiltration to environment, in order to prevent this problem, former dehumidifier is provided with switch and/or observes the water level of scale with sensing or definite water tank.Usually, observe the bottom that scale is placed in dehumidifier, reading is just very difficult if this device is placed on the floor, and conventional switch has grown in the time that later precision is just not high the sort of situation to be occurred and all can't indicate water tank near heap(ed) capacity, up to reaching heap(ed) capacity.Therefore, when going out for a long time, allow the user of dehumidifier work just not propose any warning, go out soon switch at it and just dehumidifier has been shut a hope.

Another important consideration in the design of Portable dehumidifier is that a firm and firm handle will be provided.In the past, handle is only supported by the shell of this device.This designing requirement shell will have the reinforcement of certain form, and being bearing in the heavier workpiece in the shell, and this reinforcement must cause expense to increase.Sometimes, for weight being distributed on the relative position point on the shell, the handle more than can be set.But this design not only requires the user will be with two hands when removing dehumidifier, and does not reduce the needs of the entire portion load that this shell will bear.

Because they will be used in the residential area, the Portable dehumidifying more likely is placed on wall limit or furniture next door than standard dehumidifier.Usually, establishing an individual region on the traditional dehumidifier ventilates as air outlet slit.As a result, often be blocked and be placed on desirable position to this device, therefore, reduced the efficient of this device because the air of dehumidifying fails to be convened for lack of a quorum.

The apparatus of air conditioning of the present invention is devoted to reduce or lower basically the above-mentioned shortcoming and the limitation of Portable dehumidifier in the past.For this reason, parts below the inventor has used in its novel electric air-conditioning equipment of design, promptly, a removable water tank, a condenser, an evaporimeter, a fan, a fan motor, a compressor, a humidity sensor, a humidity sensor, a circuit that between electrical components, extends, a circuit control device, a pair of half-shells and a handle that is located at least one half-shells, the improvement that has of the present invention comprises substantially: the installed part base that dividing plate that substantially vertically extends by a base that essentially horizontally is provided with from the base forms is suitable for admitting half-shells, water tank and compressor; Described dividing plate has a bottom, and it is divided into water tank district and compressor section with base, and determined that water can not the between seepage stop a middle part and a top that is suitable for supporting handle that is suitable for admitting condenser, evaporimeter, fan and fan motor.In addition, the present invention preferably includes following feature: above-mentioned installed part is to be formed by synthetic resin material mold integratedly; One checkout gear is set produces signal corresponding to mid water levels of being made in the water tank and maximum stage; A clock apparatus that is connected with circuit control device, circuit control device response temperature sensor and clock apparatus after selected low temperature reaches, work on time of a pre-selected compressor; For air is discharged at least two basic different directions, a half-shells therein is provided with the air outlet slit of at least two alternate separation; And on water tank, be provided with a shrinkage hole for reception and discharge water.

Free-revving engine of the present invention is as follows: a kind of dehumidifier that has inner support is provided, can moves dehumidifier by this supporting member; A kind of dehumidifier that can both work when producing or/and keeping in repair after shell is taken away is provided; The possibility that reduces or lower basically corrosion and enter the short circuit that electric component causes because of water, particularly the possibility of the short circuit of high-voltage electrical apparatus portion allows dehumidifier is placed near the of close wall, furniture and other article and air is flow through not obstruction of dehumidifier; Reduce or lower basically the phenomenon of water seepage from water tank; When will expiring, water tank provides an index signal to the user; And the efficient and the life-span of compressor have been improved.Aforementioned purpose of the present invention and advantage, and others, accompanying drawing and most preferred embodiment can be more readily understood after describing below reference.
