Description
Technical field
The utility model relates to the air-supply heater of cabinet type heat pump type air conditioner air conditioner indoor machine.
Background technology
Air-conditioner is a kind of utensil that environment temperature is regulated, cabinet air conditioner is divided into indoor and outdoors two parts, in indoor set, have a cover air-supply heating system, this system comprise one by spiral case 5, be arranged on the air-supply arrangement that motor 3 in the spiral case 5 and centrifugal fan 4 constitute; An indoor heat exchanger 6; And auxiliary heating element 11 (as shown in Figure 1).Indoor set drives centrifugal fan 4 rotations by motor 3 in heating the course of work, the air inlet 2 of room air by lower panel 1 sucked, it is up along the air channel to enter spiral case 5 backs, after carrying out heat exchange with indoor heat exchanger 6, send, thereby play the effect of climate comfort from the air outlet 8 of top panel 7.During heat pump type air conditioner heat pump heating operation, when outdoor environment temperature is low excessively, the heat exchange amount reduces, and will cause indoor heating effect to descend.Be to improve heating capacity, design and installation electric heater in indoor set often is when program controller is judged when satisfying certain condition, for example indoor wind pushing temperature cross low or indoor environment temperature low excessively, electric heater promptly comes into operation, because it plays auxiliary heating, so be referred to as auxiliary heater.Auxiliary heater generally has two kinds of electric heating tube and PTCR heating elements.The electrical auxiliary heater 10 of the indoor units of existing cabinet type heat pump type air conditioner generally all is to hang to be attached on the indoor heat exchanger 6, and near near the air outlet 8, the heating effect that it increased is not clearly.
The technology contents of utility model
For this reason, the purpose of this utility model is to propose the air-supply heater of the cabinet type heat pump type air conditioner air conditioner indoor machine of a kind of auxiliary heater heating outstanding effect.
For realizing above-mentioned utility model purpose, the air-supply heater of cabinet type heat pump type air conditioner air conditioner indoor machine of the present utility model, form by air-supply arrangement, indoor heat exchanger and auxiliary heating element, described air-supply arrangement has air outlet, and wherein said auxiliary heating element is arranged between the air outlet and described indoor heat exchanger of described air-supply arrangement.Preferably described auxiliary heating element is arranged on apart from the position of 3 to 10 centimetres of the air outlets of described air-supply arrangement.
Be preferably in and have roughly the blade that is provided with along the streamline of wind near the described auxiliary heating element, can improve the operating efficiency of machine, and can reduce the noise that turbulent flow is produced.A kind of very reasonable design scheme is, the blade with the heat sink design of auxiliary heating element becomes the longshore current line to be provided with so both can dispel the heat, again can rectification and reduced the quantity of parts.Wherein said auxiliary heating element is the PTCR heating element.
For ease of assembling and maintenance, on the air-conditioner shell postnotum, be provided with opening near the position that described auxiliary heating element is set, described opening is provided with cover plate, and a support that is fixed on this cover plate is arranged on described auxiliary heating element on the suitable position.
Technique scheme of the present utility model has the following advantages compared to existing technology: because design feature of the present utility model, when operation, air-flow is earlier through auxiliary heating element heat exchange, the temperature of air is improved, the air of temperature raising carries out heat exchange with indoor heat exchanger more then, can improve the condensing pressure that heats operation of heat pump under the state, also will improve consumption of compressor, can improve the heating capacity of whole heat pump like this.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is existing cabinet type heat pump type air conditioner structure;
Fig. 2 is the utility model configuration diagram;
Fig. 3 is the I enlarged drawing of Fig. 2.
Mark in the accompanying drawing: 1---lower panel, 2---air inlet, 3---motor, 4---centrifugal fan, 5---spiral case, 6---indoor heat exchanger, 7---top panel, 8---air outlet, 9---housing postnotum, the 10---auxiliary heater of prior art, 11---auxiliary heating element of the present utility model, 12---cover plate, 13---support.
The specific embodiment
Referring to Fig. 2, the air-supply heater of cabinet type heat pump type air conditioner air conditioner indoor machine of the present utility model, by comprise one by spiral case 5, be arranged on air-supply arrangement, indoor heat exchanger 6 and the heating element 11 that motor 3 in the spiral case 5 and centrifugal fan 4 constitute and form; The air channel of spiral case 5 has air outlet in air-supply arrangement; In the utility model, described auxiliary heating element 11 is arranged between the air outlet and described indoor heat exchanger 6 of described air-supply arrangement 3,4,5.
The utility model is when operation, indoor air is by in the centrifugal fan 4 inspiration air channels, pass through heating element 11 heat exchange then, the temperature of air is improved, the air of temperature raising carries out heat exchange with indoor heat exchanger 6 again, has improved the condensing pressure that heats operation of heat pump under the state, also will improve consumption of compressor, can improve the heating capacity of whole heat pump like this, and then obviously improvement adds thermal effect.
After tested, described heating element 11 is arranged on and the air outlet of spiral case 5 described in the described air-supply arrangement position at a distance of 3 to 10 centimetres, obtained to add thermal effect the most obvious.Best described PTCR heating element 11 and apart 5 centimetres of described indoor heat exchangers 6.
Referring to Fig. 3, for ease of assembling and maintenance, be provided with opening near the position that described heating element 11 is set on air-conditioner shell postnotum 9, described opening is provided with the support 13 that 12, one of cover plates are fixed on this cover plate 12 described heating element 11 is arranged on the suitable position.In assembling process, operating personnel at first are installed in PTCR heating element 11 on the support 13, will be fixed on the backboard 9 by fixtures such as screws with the cover plate 12 that support 13 is fixed together then, have finished installation procedure thus.When needing repairing, the maintenance personal pulls down cover plate 12 by pulling down hold-down screw from backboard 9.And the heating element 11 that will be installed on the support 13 of cover plate 12 together takes out, and safeguards or repairs.Make no matter be in process of production, still in use keep in repair all simple and easy to do thus.
