Abstract
Description
Technical Field
[0001] The present invention relates to a mobile air conditioner with a chassis having a hollowed-out structure.
Background Art
[0002] Chinese Patent Application Publication Specification CN115468235A discloses a ductless mobile air conditioner. The ductless mobile air conditioner includes a case, and a compressor, a condenser, an evaporator, and a water shower unit are provided in the case. The compressor, the condenser, and the evaporator communicate with each other to form a refrigeration system circulation circuit. The condenser and the water shower unit spray water on the condenser by installing the water shower unit. The water shower unit includes a water tank, a water pump, and a shower member. The water pump is used to send the water in the water tank to the shower member. A plurality of water outlet holes are provided in the shower member, and the water discharged from the water outlet holes drips onto the condenser to cool the condenser. Thereby, without installing an additional exhaust pipe to draw out the air discharged from the condenser to the outside, the temperature of the air discharged from the condenser can be lowered, and furthermore, the temperature of the air discharged from the condenser can be made normal temperature.
[0003] Since it is necessary to secure a space for placing the compressor on the side of the water tank inside the casing, the space of the water tank has to be reduced. However, the capacity of the water tank is an important factor affecting the operating time length of the water shower unit. If the capacity of the water tank is low, water has to be replenished frequently. Therefore, it is necessary to increase the capacity of the water tank.

[0007] The embodiments of this application will be further described below with reference to the attached drawings.
[0008] The chassis shown in Figures 1 to 15 is a lightweight mobile air conditioner, and includes a casing 10. The casing 10 contains a compressor 105, a condenser 101, an evaporator 106, a water shower unit, a water receiving groove 102, and a water pumping unit 103. The compressor 105, condenser 101, and evaporator 106 are interconnected to form a refrigeration system circulation circuit. The water shower unit includes a water tank 20, a water pump 104, and a shower member 105. The shower member 105 is located above the condenser 101, the water receiving groove 102 is located below the condenser 101, and the water tank 20 is located below the water receiving groove 102. The water tank 20 is detachably attached to the bottom of the casing 10. The water pump is used to send water from the water tank 20 to the shower member 105. In this embodiment, water is sent via the water supply pipe 114 into the shower member 105, which can contain water from the water pump 104. The shower member 105 is provided with a plurality of downward-facing water outlets (not shown). The water discharged from the water outlets drips onto the condenser 101. The water receiving groove 102 is used to receive the water flowing through the condenser 101. The water drawing unit 103 is provided in the water receiving groove 102 to draw the water in the water receiving groove 102 into the condenser 101. The bottom surface of the casing 10 is the chassis 106. The chassis 106 is provided with a cutout 107, which is used to house the bottom 201 of the water tank, and the bottom 201 of the water tank extends into the cutout 107.
[0009] This technical solution involves creating a space in the chassis to remove material and leave room for the water tank, thereby increasing the capacity of the water tank and reducing the frequency of hydration.
[0010] The chassis 106 is provided with two horizontally extending support legs 108 that extend into the cutouts to support the bottom 201 of the water tank. Each support leg 108 is fitted with a roller 109.
[0011] This technical solution supports the water tank with two support legs, ensuring the stability of the support for the water tank.
[0012] On both sides of the water tank 20, one convex portion 202 extends respectively. By increasing the convex portions 202, the capacity of the water tank 20 can also be increased. In the casing 10, for each of the convex portions 202, a recessed portion 110 for accommodating the convex portion 202 is provided respectively, and the bottom surface 111 of the recessed portion is used to support the bottom surface 203 of the convex portion. Thereby, the stability of the support for the water tank can be further ensured.
[0013] On the top of the water tank 20, a handle ring 30 is provided to facilitate the user to lift the water tank.
[0014] On the top of the water tank 20, a handle seat 204 is provided, and the handle ring 30 is reversibly attached to the handle seat 204.
[0015] On the top of the water tank 20, a water tank cover 40 is provided. In the water tank cover 40, a groove 401 for accommodating the handle ring 30 is provided. When the handle ring 30 is reversed, it selectively enters and exits the groove 401. Here, FIG. 4 shows that the handle ring 30 is reversed into the groove 401, while FIG. 10 shows that the handle ring 30 is reversed outside the groove 401.
[0016] In the water tank cover 40, a first through hole 402 communicating with the water tank 20 is provided, and the suction pipe 112 of the water pump passes through the first through hole 402 and is placed in the water tank 20.
[0017] The water tank cover 40 is provided with a dehydration structure for introducing the water that has fallen onto the water tank cover 40 into the water tank 20. In this embodiment, at the bottom of the water receiving groove 102, a drain pipe 113 for flowing the water in the water receiving groove 102 to the water tank cover 40 is provided. The water flowing out from the drain pipe 113 falls onto the water tank cover 40. On the other hand, when other moisture in the casing 10 (for example, moisture sputtered from the water pumping unit, condensed water generated from the evaporator, moisture adhering to the inner wall of the casing) also falls onto the water tank cover 40, it is collected by the water tank cover. The dehydration structure can introduce the water on the water tank cover 40 into the water tank 20, and avoid the accumulation of water in the casing 10 and the resulting adverse effects.
[0018] The condensed water generated in the evaporator 106 flows into the water receiving groove below the condenser, and the part that cannot be completely evaporated flows back to the water tank.
[0019] The dehydration structure includes an inclined surface 403 that slopes downward from the upper surface of the water tank cover 40. At the bottom of the inclined surface 403 of the inclined surface, a second through hole 404 communicating with the water tank 20 is provided. The water that has fallen onto the water tank cover 40 flows downward along the guide of the inclined surface 403 to the second through hole 404, and finally falls into the water tank 20 through the second through hole 404.
[0020] The water tank cover 40 is detachably attached to the top of the water tank 20. At the top of the water tank 20, an edge 205 is provided, and on the lower surface of the water tank cover 40, a plug recess 405 into which the edge 205 is inserted is provided.
[0021] The water tank cover 40 is provided with a third through hole 406 through which the handle ring 30 passes. When removing or attaching the water tank cover 40, the handle ring 30 can pass through the water tank cover 40 through the third through hole 406, avoiding the handle ring 30 from interfering with the attachment and detachment of the water tank cover 40.
[0022] In this embodiment, a locking member 407 for engaging the water tank cover 40 to the top of the water tank 20 is provided between the water tank 20 and the water tank cover 40. The water pumping unit 103 includes a motor and a flywheel attached to the rotating shaft of the motor. When the motor operates, the flywheel is rotated, and when the flywheel rotates, the water in the water receiving groove 102 can be pumped to the condenser.
