Description

Ptc heater support and be equipped with the ptc heater of this ptc heater support

Technical field

The utility model belongs to electric heater technical field, is specifically related to a kind of ptc heater support, and relates to the ptc heater being equipped with this ptc heater support.

Background technology

Aforesaid ptc heater is PTC heater, and PTC is english abbreviation (English full name is: Positive Temperature Coefficient).Due to ptc heater have that toggle speed is fast, temperature control good, functional reliability is desirable, the feature such as energy-conservation and long service life; thus be widely used as manufacturing the electrical heating elements of all kinds of electric heating appliance as air conditioner, warmer, dryer, dishwasher, water heater, food processor, heated type floor cleaner etc., even also as the vitals of the such as control and scheduling co-design device of flow restricter, filtration protector, overload protective device, degaussing controller, start-up connector and so on.Wherein, ptc heater is comparatively common as the application on the air conditioner of household electrical appliance, and be no lack of in disclosed Chinese patent literature and be seen in, as CN2640002Y(PTC heater assembly), CN2753090Y(composite type PTC device thermal), CN2392334Y(PTC heating element), the heat-conducting aluminium pipe of a CN201499328U(PTC heater and PTC heater), the PTC heater of CN2548060Y(air conditioner and fixed support), CN2512191Y(improved TV radiator and special-purpose fixing support), CN2181789Y(all-enclosed surface not charging PTC heater), CN2917152Y(enclosed positive temperature coefficient thermistor heater), the totally-enclosed adhesive type surface of CN2349737Y(not electrified PTC heating device), CN2917158Y(PTC heater determine assembling structure) and CN202998521U(PTC heater), etc..

To be applied to the ptc heater of air conditioner, generally pass through ptc heater support installing in indoor set, specifically, ptc heater need realize installing under the state matched with the evaporator of indoor set with hang by means of the ptc heater support being fixed on its one end and the tailstock (tailstock also claims supporting seat) being fixed on its other end.As is known in the industry, because the space of the indoor set of air conditioner is very limited, very little for the redundant space surplus of installing beyond ptc heater, even require that ptc heater makes volume reduce as far as possible under the prerequisite ensureing due heating power, thus how electrical insulation properties is not being lost, easy for installation and meet simultaneously and held the fuse of ptc heater, temperature controller, the volume effectively reducing ptc heater support under the prerequisite on the end of the extraction electrode of ptc heater and corresponding electric power connection line road is the technical problem that industry is paid close attention to all the time, because, if the structure of ptc heater support is lost rationally and is stopped long-pending relatively huge, so will certainly produce interference effect to the space of the indoor set of air conditioner, namely, the installing space of indoor set is forced to increase, finally cause the increase of indoor set volume.

The technical information about ptc heater support can be seen in disclosed Chinese patent literature, as CN2402093Y recommendation has " heater hold-down support ", this patent formula is configured with one for the indent rectangle mold cavity for ptc heater cooperation on hold-down support (i.e. ptc heater support), for by fixing hole (a pair) fixing for hold-down support be respectively used to set temperature and control and the thermostat installation position of fuse and the installation position, road that fuses (specifically can see Instructions Page 3 the 13 to 24 row of this patent), although this patent has the technique effect that its Instructions Page 2 the 1 to 2 section is recorded, but owing to being extended with the extension board for offering fixing hole (a pair) in the side of hold-down support, thus cause volume relatively large, and trouble is installed.

Figure 2 shows that the structure chart of the ptc heater support in prior art, apply to some extent in the air conditioner that the ptc heater support of this structure is produced in air conditioner production firm, and there is the effect with the different Qu Tonggong of aforementioned CN2402093Y to a certain extent, comprise rack body 1 and a lid 2, rack body 1 is configured with a cavity 11, this cavity 11 is formed uncovered towards the side of described lid 2, in cavity 11 and the one end being positioned at cavity 11 is configured with a pair parallel partition wall 111, by this, a pair is separated out for holding the electic protection element container cavity 1111 of electic protection element to partition wall 111, and make the ptc heater mating cavity 1112 that the space between a pair partition wall 111 is configured to for probeing into together with the electrode tip of extraction electrode for the aluminum pipe of ptc heater, a ptc heater insert port 12 communicated with ptc heater mating cavity 1112 is offered in the side of rack body 1 and corresponding to the position of ptc heater mating cavity 1112, the aluminum pipe connecting rod of ptc heater is supplied to be insinuated in ptc heater mating cavity 1112 with the electrode tip of extraction electrode by this ptc heater insert port 12, an installation reference column 13 is extended with at the opposite side of rack body 1, lid 2 adopts screw as shown in Figure 2 and is formed in cavity 11 and the screw fixed leg being positioned at the other end of cavity 11 and fixes in the described uncovered position corresponding to described rack body 1.Under state used; temperature controller (being usually called for short thermostat) as electic protection element is housed inside in one of them the electic protection element container cavity in a pair electic protection element container cavity 1111, and is accommodated in another electic protection element container cavity in a pair electic protection element container cavity 1111 as the fuse of electic protection element equally.

The ptc heater support of above-mentioned structure as shown in Figure 2 unavoidably can produce following technical problem in the use procedure of reality: one, owing to needing to form two pieces for building the partition wall 111 of a pair electic protection element container cavity 1111 in cavity 11, thus causing the volume of rack body 1 to become large and making structure be tending towards complicated, they are two years old, because ptc heater mating cavity 1112 is between a pair partition wall 111, thus a pair partition wall 111 is also implied with the effect of seizing on both sides by the arms the aluminum pipe of ptc heater, so at least one wall body of rack body 1 has occurred closing putting phenomenon, simultaneously, because the volume as the temperature controller of electic protection element and fuse is usually less, if by both with establishing in a cavity, the space of electic protection element container cavity 1111 is still more than sufficient and can not produce the sufficient flap and see elbow situation, thus for these two parts are equipped with container cavity respectively, there is blindness in structural design, they are three years old, because the structure of ptc heater mating cavity 1112 and ptc heater patchhole is lost rationally, thus be not enough to play to the aluminum pipe of ptc heater the locating effect making us expecting, after the assembling completing ptc heater, in use namely there will be the anxiety of rolling pendulum, its four, because rack body 1 shows as a plane towards one end end face of ptc heater patchhole 12, thus not there is positioning action to the radiating aluminium sheet being combined in aluminum pipe both sides, affect the stable fiting effect between ptc heater and rack body 1, they are five years old, need to be fixed by screw and the screw fixed leg be formed in cavity 11 owing to covering 2, thus install and comparatively bother, such as need to install by means of instrument (screwdriver), not only affected installation effectiveness but also increased the manipulation strength of workman, and covered 2 with the installation effect of rack body 1 also by the impact of the factor such as accountability, experience, mood of workman, especially, use screw that lid 2 and rack body 1 are fixedly existed the anxiety of electrical safety, because screw belongs to conductive component.

For above-mentioned prior art, be necessary to be improved, technical scheme described below produces under this background.

Summary of the invention
