[0040] In addition, it needs to be explained that the use of "first", "second" and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning if there is no further declaration, and therefore cannot be understood as limiting the protection scope of the utility model.

[0041] Referring to Figures 1 to 10 As shown in the figure, according to the embodiment of the utility model, a cabinet air conditioner is provided, which comprises a cabinet shell 1, the cabinet shell 1 has an air outlet 11 at the upper region thereof and an air return port (not marked in the figure) at the lower region thereof, so that Figure 1 As a reference, the air outlet 11 is on the top surface of the cabinet shell 1, and a heat exchanger 2 (evaporator or condenser) and a fan 3 are arranged in the cabinet shell 1, the heat exchanger 2 and the fan 3 are between the air return port and the air outlet 11, it can be understood that the fan 3 can drive the air outside the cabinet shell 1 to enter the internal space of the cabinet shell 1 from the air return port when the fan 3 is running, and then the air is sent out through the air outlet 11 after being heated at the heat exchanger 2, the heat exchanger 2 divides the internal space of the cabinet shell 1 into an air inlet cavity 100 and an air outlet cavity 200, wherein the air inlet cavity 100, that is, the space directly communicating with the air return port, is a normal temperature zone, and the air outlet cavity 200, that is, the space directly communicating with the air outlet 11, is a variable temperature zone (when the heat exchanger 2 is an evaporator, it is a low temperature zone), the cabinet air conditioner further comprises an electrical box 4, which contains control components (for example, an electrical module 41 composed of a circuit board and various electronic components thereon) for controlling the operation of various related components of the cabinet air conditioner, the electrical box 4 is arranged in the air inlet cavity 100 and at the top region of the air inlet cavity 100, the top region and the bottom region are referenced by the top end and the bottom end of the heat exchanger 2, the top region refers to the region above the top end of the heat exchanger 2, and the bottom region refers to the region below the bottom end of the heat exchanger 2, and the top region refers to the relatively high position region of the air inlet cavity 100.

[0042] In this technical solution, on the one hand, the electrical box 4 is arranged in the air inlet cavity 100, since the air inlet cavity 100 is a normal temperature space, it can eliminate the risk of condensation caused by arranging the electrical box 4 in the air outlet cavity 200 in the prior art, and it is not necessary to carry out heat preservation treatment on the electrical box 4 to solve the condensation problem, which saves time and effort and also reduces manufacturing cost; on the other hand, arranging the electrical box 4 in the top region of the air inlet cavity 100 makes the arrangement position of the electrical box 4 higher, which is more convenient for maintenance of the electrical box 4.

[0043] The electric appliance box 4 has a use state and a maintenance state, and the electric appliance box 4 is in different positions in the use state and the maintenance state and can be selectively switched (for example, manually changed in a switching mode, and of course, in some feasible embodiments, a corresponding position switching driving device can be used to realize the switching, for example, a rotating drive of a motor). It can be understood that the aforementioned use state refers to the position state of the electric appliance box 4 corresponding to the normal operation and use state of the cabinet air conditioner, and the maintenance state refers to the position state of the electric appliance box 4 corresponding to the state of the cabinet air conditioner in the maintenance state and not in normal use. In some embodiments, the shielding area (i.e., the wind shielding area) of the electric appliance box 4 to the air flow of the heat exchanger 2 in the use state is smaller than the shielding area of the electric appliance box 4 to the air flow of the heat exchanger 2 in the maintenance state.

[0044] In the technical solution, the electric appliance box 4 has a use state and a maintenance state that can be selectively switched, and the wind shielding area in the use state is smaller than the wind shielding area in the maintenance state. In this way, the adverse effects of the electric appliance box 4 on the air inflow can be minimized while the electric appliance box 4 is arranged in the air inflow cavity 100 during the use of the cabinet air conditioner.

[0045] In some embodiments, the electric appliance box 4 includes a box body 40 with an opening, and the aforementioned electric module 41 is arranged in the box body 40. The heat sink 411 of the electric module 41 protrudes outward from the bottom wall of the box body 40, and when the electric appliance box 4 is in the use state, the opening of the box body 40 faces upward, and the heat sink 411 faces downward.

[0046] In the technical solution, the heat sink 411 of the electric module 41 is arranged to protrude outward from the bottom wall of the box body 40, and when the electric appliance box 4 is in the use state, the heat sink 411 is arranged to face downward. In this way, the air inflow of the air inflow cavity 100 can be used to form forced air cooling for the heat sink 411, improve the heat dissipation effect of the electric appliance box 4, and further ensure the stable and reliable operation of the electric control components.

[0047] In a specific embodiment, the aforementioned box body 40 is a cuboid, and when the electric appliance box 4 is in the use state, the rectangular height of the windward side vertical wall of the cuboid is smaller than the rectangular height of the windward side vertical wall of the cuboid when the electric appliance box 4 is in the maintenance state.

The bottom of the heat exchanger 2 can be fixedly connected to the inner wall surface of the cabinet shell 1. The side of the box body 40 close to the heat exchanger 2 is hingedly connected to the top plate 13, for example, through a hinge 131. When the electric appliance box 4 is in the use state, the opening of the box body 40 is sealed by the top plate 13.

[0051] In the technical scheme, the electric appliance box 4 does not need to be separately provided with a corresponding box cover. The aforementioned top plate 13 can be used as a sealing component of the opening of the box body 40 while being used as a top end positioning and loading carrier of the heat exchanger 2, so that dustproof protection of the electric appliance box 4 is realized and the structural design is simplified.

[0052] In some embodiments, the side of the electric appliance box 4 away from the heat exchanger 2 is detachably connected to the top plate 13. For example, a corresponding lifting lug hole is arranged on the side of the electric appliance box 4 away from the heat exchanger 2. The electric appliance box 4 and the top plate 13 are fixedly connected by screwing a screw 132 into the lifting lug hole. When the electric appliance box 4 needs to be maintained, the screw 132 is disconnected.

[0053] In another feasible embodiment, the internal space is further provided with a cross beam 6. The two ends of the cross beam 6 are fixed to the two side walls of the cabinet shell 1. When the electric appliance box 4 is in the maintenance state, the cross beam 6 abuts against the outer side of the bottom wall of the box body 40 of the electric appliance box 4, that is, the outer wall surface of the side of the electric appliance box 4 facing the heat exchanger 2, so that the electric appliance box 4 is stably kept in a vertical state, which is convenient for the maintenance of the electric appliance box 4 by an operator.

In a specific embodiment, the first panel 14 is the front panel of the cabinet air conditioner, and the second panel 15 is the back panel of the cabinet air conditioner.

[0058] In the technical scheme, the first return air inlet 121 and the second return air inlet 122 are arranged on the front and back sides of the cabinet air conditioner, respectively, so as to facilitate the flexible installation of the cabinet air conditioner, and when both return air inlets are used, the air intake of the air conditioner can be significantly improved.

[0059] In some embodiments, the cabinet shell 1 further comprises a water pan 5 arranged on the bottom side of the heat exchanger 2, so as to collect the condensed water formed by the heat exchanger 2 and discharge it to the outside, and a flow passage (not shown in the figure) is formed between the water pan 5 and the first panel 14.
