Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and particularly relates to an air conditioning device. Background Art

[0002] The existing air conditioning device with a water tank includes a water tank, a water pump arranged in the water tank, and a control unit arranged outside the water tank. The control unit is electrically connected to the water pump through a lead wire to supply power to the water pump and control its operation. Specifically, an opening is provided on the water tank for the lead wire to pass through, and the lead wire extends through the opening to the outside of the water tank and is connected to the control unit.

[0003] When the control unit is arranged outside the water tank and on the side of the water pump, most of the lead wire of the water pump will be immersed in water, and the water may flow out of the water tank along the lead wire and even flow into the control unit, causing a short circuit or damage to the control unit. When the control unit is arranged outside the water tank and above the water pump, the lead wire of the water pump is in a vertical state. Even if the water tank is impacted, etc., causing the liquid level in the water tank to fluctuate and some water to splash onto the lead wire, the water droplets on the lead wire will also drip into the water tank under the action of gravity. However, when the water tank is tilted or taken out for cleaning, the water may also flow into the control unit along the lead wire, resulting in the electrical components in the control unit being damp or even damaged.

[0004] To solve the above problems, generally, glue is poured between the opening of the water tank and the lead wire, and after the glue hardens, the gap between the lead wire and the water tank is sealed. However, sealing by pouring glue will increase the processes and costs during production and manufacturing. In addition, when the water tank needs to be inspected and maintained, the lead wire may need to be pulled out from the opening, then the hardened glue at the opening needs to be damaged and re-poured with glue, resulting in inconvenient maintenance and increased costs.

The protruding post 14 communicates with the inside of the electrical box 21 through the lead - wire inlet 141.

[0080] In this embodiment, the sealing portion 13 is an elastic member, and the sealing portion 13 has elasticity and is formed of elastic materials including but not limited to silica gel, rubber, etc.

[0081] The following describes the specific implementation manners of this embodiment.

[0082] In this embodiment, during the production process or when maintaining the water tank 1, it is necessary to cut off the connection between the electrical portion 2 and the control portion 3, that is, it is necessary to install the lead - wire 4 to the control portion 3 or remove the lead - wire 4 from the control portion 3.

[0083] First, the situation when the lead wire 4 needs to be installed on the control unit 3 will be described. One end of the lead wire 4 is electrically connected to the electrical component 22 in the electrical unit 2, and the other end passes through the wire passing hole 1311 of the sealing unit 131, and the sealing unit 131 is fixed on the lead wire 4. Since the diameter of the wire passing hole 1311 is set smaller than the outer diameter of the lead wire 4, the lead wire 4 can be firmly fixed, preventing the sealing unit 131 from moving freely relative to the lead wire 4, and at the same time, water flowing into the control unit 3 from the gap between the lead wire 4 and the wire passing hole 1311 can be suppressed.

[0084] Moreover, in this embodiment, the sealing portion 13 further includes a guiding surface 135. When one end of the lead wire 4 is pushed into the wire passing hole 1311, both ends of the lead wire 4 first contact the guiding surface 135 and move inward of the wire passing hole 1311 under the guidance of the guiding surface 135. Thus, the lead wire 4 can be inserted into the wire passing hole 1311 more smoothly.

[0085] After the lead wire 4 is fixed to the sealing unit 131, the sealing unit 131 is installed on the lead wire hole 121. Specifically, the sealing unit 131 is pushed into the lead wire hole 121 from the inner side facing the electrical unit 2 to the outer side of the lead wire hole 121. Since the minimum diameter of the sealing unit 131 is greater than or equal to the diameter of the lead wire hole 121, when the sealing unit 131 is pushed into the lead wire hole 121, elastic deformation will occur, making the circumferential surface 1314 of the sealing unit 131 closely fit with the hole wall surface of the lead wire hole 121. Thus, the sealing portion 13 can be fixed in the lead wire hole 121, and the lead wire 4 can be better fixed on the control unit 3. When the lead wire 4 is subjected to a pulling force, a part of the force will be dispersed to the sealing portion 13, thereby suppressing the lead wire 4 from falling off or even being damaged from the control unit 3.

[0086] In addition, since the circumferential surface 1314 of the sealing unit 131 closely fits with the hole wall surface of the lead wire hole 121, water entering the control unit 3 from the gap between the circumferential surface 1314 of the sealing unit 131 and the hole wall surface of the lead wire hole 121 can be suppressed.

[0087] Furthermore, in this embodiment, since the sealing portion 13 further includes an outer sealing rib 133 and an inner sealing rib 132, and the diameter of the outer sealing rib 133 is smaller than that of the inner sealing rib 132, when the sealing unit 131 moves from the inner side of the electrical portion 2 towards the lead hole 121, the outer sealing rib 133 contacts the wall surface of the lead hole 121 and undergoes elastic deformation under the action of force. When the diameter of the outer sealing rib 133 is compressed to be less than or equal to the diameter of the lead hole 121, the outer sealing rib 133 will pass through the lead hole 121 and penetrate through the water tank cover 12. When the outer sealing rib 133 moves through the lead hole 121 to the outside of the lead hole 121, the outer sealing rib 133 no longer contacts the wall surface of the lead hole 121 and thus is no longer squeezed, and the outer sealing rib 133 resumes its original size. Since the distance from the circumferential surface of the outer sealing rib 133 to the center of the lead hole 121 is greater than the radius of the lead hole 121, the sealing portion 13 will be fixed on the lead hole 121, preventing the sealing portion 13 from moving and falling off from the outside to the inside of the lead hole 121.

[0088] In addition, since the distance from the circumferential surface of the inner sealing rib 132 to the center of the lead hole 121 is greater than the radius of the lead hole 121, it can also prevent the sealing portion 13 from continuing to move from the inside to the outside of the lead hole 121. Thus, the sealing portion 13 and the lead 4 are fixed at the lead hole 121.

[0089] Moreover, since the diameter of the inner sealing rib 132 is greater than that of the outer sealing rib 133, when the sealing portion 13 is pushed from the inside to the outside of the lead hole 121, it will be able to pass through the lead hole 121 more smoothly, which is beneficial to the convenience of installation.

[0090] Furthermore, in this embodiment, since the sealing portion 13 is provided with a guiding surface 136, and the guiding surface 136 is provided on the outer sealing rib 133. When the sealing portion 13 is pushed from the inside to the outside of the lead hole 121 into the lead hole 121, the guiding surface 136 on the outer sealing rib 133 first contacts the wall surface of the lead hole 121. Since the guiding surface 136 inclines towards the center of the wire passing hole 1311, the sealing portion 13 will enter the lead hole 121 more smoothly under the guidance of the guiding surface 136. This prevents the sealing portion 13 from tilting due to interference between the edge of the sealing portion 13 and the wall surface of the lead hole 121, so that it cannot be correctly installed in place, resulting in the sealing portion 13 falling off from the lead hole 121, or water flowing into the control portion 3 through the gap between the sealing portion 13 and the lead hole 121.

[0091] Furthermore, in this embodiment, the water tank 1 is further provided with a protruding post 14, and the protruding post 14 clamps a sealing rib on the inner wall surface of the water tank cover 12 corresponding to the position of the lead hole 121. Thus, when the sealing portion 13 is fixed to the lead hole 121, the protruding post 14 pushes the sealing portion 13 toward the lead hole 121 side. Even if the sealing portion 13 is not installed in place or becomes loose due to aging of the sealing portion 13, it will be fixed at the lead hole 121 under the support of the protruding post 14. Thereby, the detachment of the sealing portion 13 is avoided.

[0092] Moreover, in this embodiment, the distance between the protruding post 14 and the plane where the lead hole 121 is located is less than the thickness of the inner sealing rib 132. Therefore, when in the installed state, the protruding post 14 squeezes the inner sealing rib 132 toward the lead hole 121, making the inner sealing rib 132 further closely adhere to the outer periphery of the lead hole 121. Thereby, further preventing water from flowing into the control portion 3 through the gap between the sealing rib and the lead hole 121.

[0093] In addition, in this embodiment, a pressurizing rib 134 is provided on the inner surface 1313 of the sealing unit 131, that is to say, the pressurizing rib 134 is provided on the inner sealing rib 132 of the sealing unit 131. Therefore, when the protruding post 14 squeezes the sealing rib toward the lead hole 121, it will contact the pressurizing rib 134. Thus, the contact area between the protruding post 14 and the sealing unit 131 is reduced, which can increase the deformation amount of the sealing rib, so that the sealing rib fits more closely to the outer periphery of the lead hole 121.

[0094] Furthermore, when the water tank 1 needs to be inspected and maintained, etc., the lead 4 needs to be removed. At this time, one end of the lead 4 is removed from the control portion 3, and the sealing portion 13 is removed from the lead hole 121 toward the inner side of the water tank 1. Since the diameter of the outer sealing rib 133 is smaller than the diameter of the inner sealing rib 132, when the sealing portion 13 is removed from the lead hole 121, the sealing portion 13 is dragged from the outside to the inside of the lead hole 121. The outer sealing rib 133 interferes with the outer peripheral edge of the lead hole 121 and deforms, compresses inward and passes through the lead hole 121, and finally completely passes through the lead hole 121. After falling off from the lead hole 121, it resumes its original shape and size. Thus, it is convenient for inspection and maintenance, and after inspection and maintenance, the sealing portion 13 can be fixed to the lead hole 121 again, thereby fixing the lead 4 and sealing the lead hole 121. The installation and disassembly operations of the sealing portion 13 are convenient, which is beneficial to the convenience of inspection and maintenance.

[0095] Thus, an air conditioning device is provided that can fix the lead 4 while ensuring the sealing of the lead hole 121 and the sealing portion 13 is easy to install and disassemble.

[0096] In addition, in this embodiment, the opening of the electrical box 21 is provided at the bottom, the box cover 212 covers the opening, and the protruding post 14 is provided on the box cover 212. After the sealing portion 13 is installed into the lead hole 121, the box cover 212 is installed from the bottom to the top of the water tank 1, so that the protruding post 14 contacts the sealing portion 13 and presses the sealing portion 13 to make it closely fit on the outer peripheral edge of the lead hole 121.

[0097] Moreover, since the lead inlet 141 is provided on the protruding post 14, after the lead 4 and the sealing portion 13 are fixed in the lead hole 121, the other end of the lead 4 passes through the lead inlet 141 and enters the interior of the electrical box 21 to be connected to the electrical component 22.

[0098] Since the liquid through hole 2121 is provided on the electrical portion 2, the liquid will enter the electrical box 21 through the liquid through hole 2121. Thus, the electrical component 22 can process the liquid in the water tank 1.

[0099] Due to the provision of the sealing portion 13, even when the water tank 1 is tilted or the like, it is difficult for the liquid to enter the control portion 3 through the lead hole 121.

[0101] Second Embodiment

[0102] The following describes the second embodiment of the present disclosure. Among them, the same or similar structures as those in the first embodiment will not be described in detail.

[0103] In this embodiment, the air conditioning device further includes a lighting portion 7.

[0104] The lighting portion 7 is used for sterilizing the liquid in the water tank 1, is provided on the top surface of the water tank 1, and is arranged facing the bottom surface of the water tank 1. The lighting portion 7 includes a lighting unit 71. The lighting unit 71 is electrically connected to the control portion 3 and includes a light emitting surface 711. The light emitting surface 711 is the surface of the lighting unit 71 that emits light and is arranged facing the bottom surface of the water tank 1. In this embodiment, the lighting unit 71 is an ultraviolet lamp.

[0105] Furthermore, in this embodiment, the lighting portion 7 further includes a condenser tube 72. The condenser tube 72 is a hollow tube shape extending from the outer periphery of the lighting unit 71 to the lower side of the light emitting surface 711, and can be a tube shape surrounding the entire circumference of the lighting unit 71 or a tube shape surrounding a part of the outer periphery of the lighting unit 71.

[0106] The water tank 1 further includes a liquid level viewing window 8 that enables the liquid level inside the water tank 1 to be seen from outside the water tank 1. The liquid level viewing window 8 is provided on the box body 11 of the water tank 1 and includes a viewing window opening provided on the box body 11 and a light-transmitting viewing window baffle that seals the viewing window opening.

[0107] The water tank 1 further includes a shielding piece 9 provided between the liquid level viewing window 8 and the lighting part 7. In this embodiment, the shielding piece 9 is provided on the lid 212 of the electrical box 21 and extends from above the lighting part 7 towards the bottom of the water tank 1.

[0108] The following describes the specific implementation manners of this embodiment.

[0109] In this embodiment, by providing a lighting part 7 inside the water tank 1, the liquid stored in the water tank 1 is disinfected and sterilized. Since the lighting part 7 is provided on the top surface of the water tank 1 and faces the bottom surface of the water tank 1. When the lighting part 7 is powered on and operates, it can emit light rays with disinfection and sterilization effects, such as ultraviolet light, and irradiate the inside of the water tank 1. Since the lighting part 7 is provided on the top surface of the water tank 1, its irradiation range can be increased as much as possible, and the distance between the lighting part 7 and the bottom surface of the water tank 1 is relatively far, so that the emitted light rays can have sufficient distance and space to be reflected and scattered through the wall surface of the water tank 1, expanding the range of light irradiation for sterilization, thereby improving the efficiency of disinfection or sterilization.

[0110] Furthermore, since a condenser tube 72 is further provided below the light-emitting surface 711, the condenser tube 72 can prevent the light rays emitted from the light-emitting surface 711 from being scattered too quickly, so that the light rays are irradiated towards the bottom surface of the water tank 1 through the condenser tube 72, thereby making the light rays be intensively reflected and increasing the irradiation range and efficiency.

[0111] Moreover, in this embodiment, the lighting part 7 is provided around the electrical part 2. Before the liquid is processed by the electrical part 2, it will first be disinfected and sterilized by the lighting part 7, which can improve the efficiency of disinfection and sterilization.

[0112] Furthermore, the water tank 1 is provided with a liquid level viewing window 8, so that the user can directly see the water level inside the water tank 1 without taking out the water tank 1, which is convenient for maintenance. At the same time, since a shielding piece 9 is provided inside the water tank 1, it can inhibit the light rays emitted by the lighting part 7 from irradiating outside the water tank 1 through the liquid level viewing window 8, thereby reducing the risk of the human eye being stimulated or damaged by the light rays.

[0113] Moreover, in this embodiment, the shielding piece 9 is provided on the lid 212 of the electrical box 21, which can cooperate with the electrical box 21 to further shield the lighting part 7 while saving costs.
