Below with reference to the accompanying drawings describe in detail according to the chassis assembly for air-conditioner outdoor unit of the present invention.
As shown in Figure 1, according to the chassis assembly for air-conditioner outdoor unit of the embodiment of the present invention, comprising: chassis body 10, heater 20 and temperature inductor 30.
Specifically, chassis body 10 has installation portion (not shown).
Heater 20 is removably mounted on described installation portion, for heating chassis body 10.
Temperature inductor 30 is arranged in chassis body 10, for detecting the temperature of chassis body.
According to the chassis assembly for air-conditioner outdoor unit of the embodiment of the present invention, be provided with the heater 20 heated chassis body 10, can effectively prevent condensed water from congealing into ice in chassis body 10, structure is simple, cost is low.
According to an example of the present invention, heater 20 can be electric heating wire circle dish or electromagnetic heating coil disc.Thus, the mode of electrical heating or Electromagnetic Heating can be adopted to heat chassis, heating is quick and heating effect is even.
According to an example of the present invention, described installation portion is made up of the multiple buckles 101 with described heater coil disc clamping.Advantageously, multiple buckle 101 interval in chassis body 10 is arranged and line between adjacent between two in multiple buckle 101 two is configured to annular.Such as, multiple buckle 101 can be three buckles and line between two adjacent between two in these three buckles 101 is configured to triangle.As shown in Figure 1, multiple buckle 101 is four buckles and line between two adjacent between two in four buckles is configured to rectangle.Thus, the installation and removal of heater coil disc are convenient to.
According to an example of the present invention, described installation portion is formed in upper (namely as shown in Figure 1 substantially in the face of the direction of reader) of chassis body 10 on the surface.That is, the setting position of heater 20, between chassis body and outdoor unit main body, while heater 20 pairs of chassis body heat, also can be heated by the condenser of heat radiation to air-conditioner outdoor unit, improves defrost effect further.
According to the air-conditioner outdoor unit of the embodiment of the present invention, comprising: outdoor unit main body and chassis assembly.Described chassis assembly is connected with described outdoor unit main body.Wherein, described chassis assembly is the chassis assembly for air-conditioner outdoor unit according to above-mentioned any one.
Fig. 2 shows the defrosting method of the above-mentioned air-conditioner outdoor unit according to the embodiment of the present invention.
Described air-conditioner outdoor unit comprises the controller (not shown) be connected with temperature inductor 30 with heater 20 respectively.Comprise the following steps:
1) described controller judges whether described air-conditioner outdoor unit is in heating mode.
2) whether temperature inductor 30 detects the temperature of chassis body 10 lower than the first preset temperature (temperature such as below freezing, now, the condensed water on chassis meets cold junction ice, until stopping state appears in discharge outlet place, chassis).
3) if described air-conditioner outdoor unit is in heating mode and the temperature of chassis body 10 that temperature inductor 30 detects heats lower than controller control heater described during the first preset temperature 20 pairs of chassis body 10.Thus, can the condensed water that chassis body 10 heats to make to congeal into ice be melted.
According to an example of the present invention, described defrosting method also comprises step: when 4) temperature inductor 30 detects the temperature of chassis body 10 higher than the second preset temperature, and described controller control heater 20 stops heating chassis body 10.Second preset temperature mentioned here refers to the temperature being enough to ice is melted completely.Certainly, the scheduled time can also be kept to ensure that the ice on chassis melts completely further, to guarantee that air-conditioning normally works by making the second preset temperature.
In other words, as shown in Figure 1, the middle position of chassis body 10 is provided with four buckles 101, and buckle 101 is used for fixing heater coil disc.This heater coil disc can be dismantled, and its effect mainly can be heated to chassis body.Discharge outlet place, chassis is provided with temperature inductor 30, and the circuit unification of heater coil disc and temperature inductor is controlled by air-condition circuits system controller.After outdoor air-conditioner heats for a long time, if when outdoor environment temperature is lower, the fin on condenser chassis will form ice sheet with during water Long contact time again simultaneously, until there is stopping state in discharge outlet place, chassis, after now temperature inductor 30 senses the temperature needing defrosting, instruction is sent to heater coil disc by controller of air conditioner, startupization frost function, heater coil disc starts heating chassis after receiving instruction immediately, and the time of heating chassis body determines according to the temperature inductor 30 at discharge outlet place.If after reaching the temperature that frost melted, after heater coil disc receives the instruction of controller of air conditioner stoppingization frost, heater coil disc stops heating chassis body 10.By above measure by melts Cheng Shui, guarantee that air-conditioning normally heats.
Beneficial effect according to the chassis assembly for air-conditioner outdoor unit of the embodiment of the present invention is:
1. electrical heating coil is accelerated faster than ribbon heater, and the efficiency of heating surface is higher.A place that heating-condensing device contacts with chassis, ribbon heater, other ground not having a heating tape still may frost, and electrical heating coil heats to whole chassis, heating evenly, while the heating of chassis, because heat radiation also can exist temperature radiation effect to the defrost of condenser, can reduce condenser defrost time and the number of times of complete machine, that improves air-conditioner heats level. meet the air-conditioning heating of even outdoor subzero 30 degree of lower temperature.
2. this device can be sold as the form of accessory, and user can follow the needs according to self to carry out selection and buy, and allows consumer's transparent consumption.
3. to be more convenient for except two aspects above after-sales service, if coil panel bad after need not take whole off-premises station apart and overhaul, can change separately, greatly reduce the difficulty of maintenance personal.
In the description of this description, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present invention or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
Although illustrate and describe embodiments of the invention above, be understandable that, above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, those of ordinary skill in the art can change above-described embodiment within the scope of the invention when not departing from principle of the present invention and aim, revising, replacing and modification.
