In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be to be connected directly, the connection inside two elements can also be can be indirectly connected through an intermediary.For this field
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
As Figure 1-Figure 4, the present invention provides a kind of electrical box, which includes ontology 1 and can be fastened on institute
The box cover 2 on ontology 1 is stated, the ontology 1 is for installing electricity piece necessary to operation of air conditioner, including driving plate, control panel, filter
Wave plate, reactor, terminal block etc.；The box cover 2 is formed with after fastening with ontology 1 for being fastened on the ontology 1, box cover 2
The accommodation space of above-mentioned electricity piece can be accommodated.The bottom of the box cover 2 is provided with air inlet 21, the top setting of the ontology 1
There is gas outlet 11.Electrical box is facilitated the electricity piece heat dissipation inside electrical box is more complete using radiating mode from bottom to top.
Continue as shown in Figures 2 and 3, ontology 1 of the present invention is formed with heat dissipation channel 13, institute at the gas outlet 11
The top that heat dissipation channel 13 is the ontology 1 is stated to protrude from the ontology 1 and extend to form to the back of the ontology 1 hollow
Channel, the open bottom that the heat dissipation channel 13 is corresponded on the ontology 1 are provided with wind deflector 3.
The setting of present invention heat dissipation channel among the above, increases outside electrical box or rainwater or insect enter in electrical box
The return trap in portion, to increase the resistance of rainwater and insect entrance；In addition, can by the setting in the exit of heat dissipation channel
The baffle for changing wind direction, prevents air conditioner body interior air-flow from flowing backward inside electrical box, improves radiating efficiency；It keeps away simultaneously
Exempt from reverse irrigation air-flow and take rainwater to enter inside electrical box, plays waterproof action.Pass through matching for above-mentioned heat dissipation channel and wind deflector
Setting is closed, rainwater is further avoided and insect enters to probability inside electrical box, so that extend electricity piece uses the longevity
Life.
It illustrating, the ontology 1 includes the backboard being vertically arranged, and is set to the upper cover at the top of the backboard, on
Stating the heat dissipation channel is the hollow space formed between the upper cover at the top of the backboard, and the backboard and the upper cover are preferred
It is spot welding connection.
In order to further prevent water from entering in heat dissipation channel and spread to electrical box cavity, correspond at the top of the ontology 1
At least one convex ribs 12 are provided at the heat dissipation channel 13.The convex ribs 12 are higher than 1 top of ontology, and it is logical to cross at heat dissipation
In road 13, and barrier tape is formed in heat dissipation channel, enter to realize secondary barrier rainwater.
Because the air flow channel of electrical box of the invention is from bottom to top, it is preferred that the transverse width of the wind deflector 3 is greater than
The opening width of the heat dissipation channel 13, to prevent the air outside electrical box from entering to the heat dissipation channel.
As shown in figure 4, the box cover 2 of the invention corresponds to the bullet for being provided with salable conducting wire 4 at the air inlet 21
Property pad 5.Because the conducting wire of electrical box is connect from air inlet with the external world, therefore, at the air inlet of electrical box needing to reserve can pass through
The hole of conducting wire, but because of the presence of the hole, the entrance of rainwater or insect is easily led to, therefore, one side of elastic cushion of elasticity is set
It will not be damaged in face of conducting wire, on the other hand can play sealing function.
As shown in Figure 3, it is preferred that the front height of the ontology 1 is greater than the rear-side height of the ontology 1.In this way
Keep heat dissipation channel inclined, when rainwater enters to heat dissipation channel, the resistance being subject to is bigger.
Preferably, the air inlet 21 is the multiple holes being set on the box cover 2.The gas outlet 11 is is set to
State multiple holes on ontology 1.The hole of the air inlet 21 and/or the bore dia of the gas outlet 11 are less than 3mm.Small pore-like into
Port and gas outlet can avoid Siphonophora insect and enter in electrical box, cause electricity piece that short circuit occurs.
Such as Fig. 5, the present invention also provides a kind of air conditioner, which includes indoor unit and outdoor unit, the outdoor unit
Inside it is provided with electrical box described in any of the above-described embodiment.Because being described in detail above-mentioned, details are not described herein.
Further, the outdoor unit includes the heat exchanger 7 for being set to the outdoor unit side, and is set to the room
Fan 6 at the top of outer machine, the electrical box are vertically arranged on the outdoor unit inner sidewall.
Air conditioner of the invention, because including the electrical box with wind deflector and heat dissipation channel, when top blower starts, gas
It flows to after reaching electrical box top, is entered heat dissipation channel at electrical box top outlet inlet and flowed backward, along heat dissipation channel
It flows downward out.And the setting of wind deflector, it is therefore prevented that electrical box outlet air liquidates with total airflow generation inside air-conditioner outdoor unit, enhances
Outlet air air flow rate.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
