[0040] Figures 1 to 14The figure is a specification drawing of the air conditioner of the present invention. The present invention provides an air conditioner, which can cool or heat the indoor environment to adjust the temperature of the indoor environment. The air conditioner adopts a new drainage valve installation method, which can reduce the rust caused by the use of screws and improve the stability of drainage valve installation.

[0041] See also Figure 1 In one embodiment, the air conditioner may be a mobile air conditioner or a cabinet air conditioner. For the mobile air conditioner, the mobile air conditioner includes a chassis 100, a shell mounted on the chassis 100, an indoor heat exchanger, and an outdoor heat exchanger. The shell has an outdoor heat exchange chamber and an indoor heat exchange chamber located above the outdoor heat exchange chamber; the outdoor heat exchanger is mounted in the outdoor heat exchange chamber; and the indoor heat exchanger is mounted in the indoor heat exchange chamber.

[0042] When the mobile air conditioner is cooling, the air in the indoor environment enters the indoor heat exchange chamber, forms cold air after heat exchange in the indoor heat exchanger, and then the cold air is blown out to the indoor environment to achieve cooling of the indoor environment; at the same time, the air in the indoor environment or the outdoor environment enters the outdoor heat exchange chamber, forms hot air after heat exchange in the outdoor heat exchanger, and the hot air is finally discharged to the outside through the exhaust pipe.

[0043] See also Figure 1 and Figure 2 In one embodiment, the air conditioner includes a chassis 100 and a drain valve 400. The chassis 100 is configured with a water receiving tank 101 and a water outlet 102 connected to the water receiving tank 101. The drain valve 400 is installed on the chassis 100. The drain valve 400 includes a valve seat 410 and a valve stem 420 connected to the valve seat 410. The valve stem 420 can move relative to the valve seat 410 to open and close the water outlet 102. The chassis 100 is also configured with a valve slot 170 (such as Figure 7 and Figure 8 ), the circumferential structure of the valve groove 170 has a limit member 173, and the limit member 173 is suitable for fixing the valve seat 410 in the valve groove 170.

[0044] Specifically, the water receiving tank 101 of the bottom plate 100 can be used to accumulate condensed water generated by the heat exchange component, and the bottom plate 100 can be configured with a water outlet 102 at the bottom of the water receiving tank 101, so that the water in the water receiving tank 101 is directly discharged from the water outlet 102. Alternatively, the bottom plate 100 is configured with a water outlet 102 on one side of the water receiving tank 101, and a drainage channel (such as a drain channel) is provided between the water outlet 102 and the water receiving tank 101. Figure 4 The water in the water receiving tank 101 passes through the water outlet 102 of the drainage channel and is finally discharged from the water outlet 102. The latter embodiment is specifically adopted here.

[0045] The drain valve 400 and the water outlet 102 are arranged opposite to each other, and the drain valve 400 can open and close the water outlet 102. The top surface of the valve seat 410 of the drain valve 400 is configured with a wiring terminal 412, and a driving shaft 411 extends from one end of the valve seat 410 close to the water outlet 102, and the driving shaft 411 is connected to the valve stem 420. When the water outlet 102 is closed, the valve seat 410 of the drain valve 400 drives the valve stem 420 to move toward the water outlet 102 through the driving shaft 411, so that the valve stem 420 blocks the water outlet 102, thereby closing the water outlet 102; when the water outlet 102 needs to be opened, the valve seat 410 of the drain valve 400 drives the valve stem 420 to move in the opposite direction through the driving shaft 411, so that the valve stem 420 withdraws from the water outlet 102, thereby opening the water outlet 102.

[0046] When installing the drain valve 400, first install the valve seat 410 of the drain valve 400 into the valve groove 170, and align the valve stem 420 of the drain valve 400 with the water outlet 102; then, the valve seat 410 of the drain valve 400 is limited in the valve groove 170 by the limiter 173 on the circumference of the valve groove 170, so as to fix the drain valve 400. As for the structural type of the limiter 173, the limiter 173 is a non-screw structure, for example, the limiter 173 can be a limiter buckle, an elastic pressing sheet, a self-locking cable tie, etc. The number of limiters 173 can be designed according to the size of the drain valve 400, and can be one or two or more. As for the specific shape and structure of the limiter 173, it will be described in detail later.

[0047] The technical solution of the present invention is to construct a valve groove 170 for installing the water supply and drainage valve 400 on the chassis 100, and to construct a limit member 173 around the valve groove 170, so that the drain valve 400 can be confined in the valve groove 170 by using the limit member 173, thereby eliminating the need to use screws to fix the drain valve 400, reducing the use of screws, and further reducing rust caused by the use of screws, thereby improving the stability of the installation of the drain valve 400.

[0048] See also Figure 3 and Figure 4 In one embodiment, the chassis 100 is further configured with a drainage groove 180 spaced apart from the valve groove 170, and a water outlet 102 (such as Figure 7 and Figure 8 ), the water outlet 102 connects the drainage groove 180 and the water receiving groove 101; the valve stem 420 of the drainage valve 400 is located in the drainage groove 180.

[0049] Specifically, since the valve seat 410 of the drain valve 400 is installed in the valve groove 170, the driving shaft 411 of the valve seat 410 penetrates from the valve groove 170 into the drain groove 180 and is connected to the valve stem 420. The driving shaft 411 of the valve seat 410 drives the valve stem 420 to move forward to block the water outlet 102 and close the water outlet 102, and drives the valve stem 420 to move backward to withdraw from the water outlet 102 and open the water outlet 102. After the water outlet 102 is opened, the water in the water receiving tank 101 enters the drain groove 180 from the water outlet 102, and then is discharged from the drain groove 180.

[0050] See also Figure 8 and Fig.11 In order to facilitate the drainage of the water in the drain groove 180, a drain pipe 130 is constructed on the lower surface of the chassis 100. One end of the drain pipe 130 is connected to the drain groove 180, and the other end of the drain pipe 130 is provided with a water plug 300. The water plug 300 includes a plug head 310 inserted and matched with the drain port of the drain pipe 130, and a fixing bar 320 connected to the plug head 310, and the fixing bar 320 is connected and fixed to the chassis 100. After the plug head 310 of the water plug 300 is pulled out from the drain pipe 130, the water in the drain groove 180 is discharged outward through the drain pipe 130; at this time, since the fixing bar 320 of the water plug 300 is fixed to the chassis 100, the water plug 300 is not easy to be lost. After the drainage is completed, the water plug 300 is inserted into the drain pipe 130 to block the drain pipe 130 to prevent water leakage.

[0051] It is considered that when the valve seat 410 of the drain valve 400 drives the valve stem 420 to move, the valve stem 420 may be laterally offset, making it difficult for the valve stem 420 to correspond to the water outlet 102, thereby increasing the difficulty of fully opening or closing the water outlet 102. To avoid this situation, guide ribs 181 are optionally configured on opposite sides of the drain groove 180, and the two guide ribs 181 extend from the edge of the water outlet 102 toward the valve groove 170, and a guide groove for the movement of the valve stem 420 is defined between the two guide ribs 181.

[0052] After the drain valve 400 is installed, the two guide ribs 181 are located on opposite sides of the valve stem 420, so that the valve stem 420 is confined in the guide groove between the two guide ribs 181, so that the valve stem 420 can only move along the extension direction of the guide ribs 181, and is not prone to lateral deviation, thereby achieving precise alignment of the valve stem 420 and the water outlet 102, effectively reducing the difficulty of fully opening or closing the water outlet 102.

[0053] See also Figure 5 and Figure 6In one embodiment, the chassis 100 is configured with a plurality of stoppers 173 around the valve groove 170 to fix the drain valve 400. The specific arrangement of the stoppers 173 can be designed according to the shape and structure of the valve groove 170. Optionally, the valve groove 170 has a front wall plate 171 opposite to the water outlet 102, and side wall plates 172 extending backward from both sides of the front wall plate 171. The two side wall plates 172 are configured with stoppers 173. The stoppers 173 on the two side wall plates 172 are respectively buckled with the opposite two sides of the valve seat 410 to fix the valve seat 410 to the valve groove 170.

[0054] Specifically, a plurality of stoppers 173 are constructed on the two side wall plates 172 of the valve slot 170, and the stoppers 173 on each side wall plate 172 are arranged at intervals along the length direction of the valve slot 170. The stoppers 173 on the two side wall plates 172 are respectively buckled with the opposite two sides of the valve seat 410, so as to stably fix the valve seat 410 in the valve slot 170 and improve the stability of the installation of the valve seat 410. It is worth mentioning that the stoppers 173 preferably have a certain elasticity, so as to facilitate the application of external force to cause the stoppers 173 to deform elastically and disassemble the valve seat 410.

[0055] See also Figure 5 and Figure 6 Optionally, the limiting member 173 includes a limiting arm 1731 protruding upward from the upper edge of the side wall plate 172, and a hook 1732 extending from the upper end of the limiting arm 1731 toward the upper side of the valve slot 170, and the limiting member 173 is locked with the side of the valve seat 410 through the hook 1732. The limiting arm 1731 of the limiting member 173 can limit the left or right movement of the valve seat 410, so that the valve seat 410 cannot fall out laterally; the hook 1732 of the limiting member 173 limits the upward movement of the valve seat 410, so that the valve seat 410 cannot fall out upward.

[0056] See also Figure 7 and Figure 8 In one embodiment, the rear end of the valve groove 170 away from the front wall plate 171 is formed with an opening, and the opening can prevent the surrounding of the valve groove 170 from forming a closed structure. During the operation of the drain valve 400, the heat generated by the valve seat 410 can be dissipated outward from the opening. Alternatively, water dripping into the valve groove 170 can be discharged from the opening to avoid water accumulation and leakage of the drain valve 400.

[0057] In order to prevent the valve seat 410 of the drain valve 400 from falling out of the opening of the valve slot 170, a limiting column 174 is configured at the opening and is located between two side wall plates 172 of the valve slot 170. The limiting column 174 is adapted to abut against the rear end of the valve seat 410. The valve seat 410 is blocked by the limiting column 174 and is difficult to fall out of the opening of the valve slot 170.

[0058] Furthermore, a break notch 125 can be formed in the side plate 120 of the chassis 100 near the opening of the valve slot 170, and the break notch 125 corresponds to the opening of the valve slot 170; the rear ends of the two side wall plates 172 of the valve slot 170 extend toward the break notch 125 with an extension plate 103, and a channel 104 connecting the opening and the break notch 125 is formed between the two extension plates 103.

[0059] Specifically, the chassis 100 can form a break notch 125 during the process of manufacturing the chassis 100, and the break notch 125 can separate the side plate 120 where the chassis 100 is located, so as to facilitate the chassis 100 to be demolded. The break notch 125 is connected to the opening of the valve slot 170 through the channel 104 between the two extension plates 103, thereby forming a heat dissipation channel or a drainage channel. In other words, the heat generated by the valve seat 410 can be dissipated from the opening of the valve slot 170, through the channel 104, and the break notch 125 to the outside of the mobile air conditioner, thereby preventing the valve slot 170 from being burned due to the accumulation of more heat. Similarly, if there is water in the valve slot 170, the water can also be discharged from the opening of the valve slot 170, through the channel 104, and the break notch 125 to the outside of the mobile air conditioner, thereby preventing the valve slot 170 from leaking electricity due to water accumulation.

[0060] See also Figures 6 to 8 It is considered that if the bottom surface of the valve seat 410 and the bottom surface of the valve groove 170 are close together, the contact area between the two is large, and the heat generated by the valve seat 410 is easy to accumulate at the contact position between the two, making it difficult for the heat to dissipate, and there is a risk of the valve seat 410 heating up and burning.

[0061] In order to solve the above problems, the bottom surface of the valve groove 170 is also provided with a plurality of supporting protrusions 176, which are supported on the bottom surface of the valve seat 410 to separate the bottom surface of the valve seat 410 from the bottom surface of the valve groove 170. In this way, a first gap can be formed between the bottom surface of the valve seat 410 and the bottom surface of the valve groove 170, and the first gap forms a good heat dissipation channel, which helps the drain valve 400 to dissipate heat outward. It is worth mentioning that the height of the supporting protrusion 176 protruding from the bottom surface of the valve groove 170 should be less than the height of the limiting column 174 protruding from the bottom surface of the valve groove 170, so as to ensure that the limiting column 174 can be used for the rear end of the valve seat 410 to abut against.

[0062] Similarly, if the side of the valve seat 410 and the side wall plate 172 of the valve groove 170 are close together, the contact area between the two is large, and the heat generated by the valve seat 410 is easily accumulated at the contact position between the two, making it difficult for the heat to be dissipated, and there is a risk of the valve seat 410 being burned due to the temperature rise. To solve this problem, positioning protrusions 175 are convexly provided on the inner wall surfaces of the two side wall plates 172 of the valve groove 170. The positioning protrusions 175 extend forward from the rear end of the side wall plate 172 to the front wall plate 171. The positioning protrusions 175 on the two side wall plates 172 cooperate to abut against the two side surfaces of the valve seat 410 to separate the side surfaces of the valve seat 410 and the side wall plates 172.

[0063] Specifically, after the valve seat 410 is installed in the valve groove 170, the positioning protrusions 175 on the two side wall plates 172 of the valve groove 170 respectively abut against the two side surfaces of the valve seat 410, similar to the two positioning protrusions 175 clamping and fixing the valve seat 410. The valve seat 410 is blocked by the positioning protrusions 175, and the two side surfaces of the valve seat 410 cannot contact the side wall plates 172 of the valve groove 170, so that a second gap is formed between the side surface of the valve seat 410 and the side wall plates 172, and the second gap is connected with the first gap to form a good heat dissipation channel, which greatly improves the heat dissipation effect of the drain valve 400.

[0064] See also Figure 7 and Fig.11 Based on any of the above embodiments, the chassis 100 is constructed with a water receiving groove 101 and an installation position 105 for installing a compressor; the chassis 100 is constructed to form an electrical appliance accommodating area 106 between the water receiving groove 101 and the installation position 105, and the electrical appliance accommodating area 106 is suitable for accommodating and installing the electrical components; the drain valve 400 is located in the electrical appliance accommodating area 106.

[0065] Specifically, the water receiving tank 101 on the chassis 100 is located correspondingly below the outdoor heat exchanger to receive the condensed water generated by the outdoor heat exchanger. Usually, a large vacant area is formed between the water receiving tank 101 and the installation position 105 for installing the compressor, so that the vacant area can be constructed to form an electrical appliance accommodating area 106 to accommodate and install electrical appliance components, making full use of the internal space of the mobile air conditioner and effectively regulating the distribution of internal components of the mobile air conditioner.

[0066] See also Figure 7 and Fig.11 In one embodiment, the electrical component also includes a first water level detector 710, which is installed in the electrical appliance accommodating area 106 to detect the first water level of the electrical appliance accommodating area 106 and feed back a first water level signal to the control device of the air conditioner, so that the control device receives the first water level signal to alarm or drain water.

[0067] In order to ensure that the chassis 100 can drain the water on the bottom plate 110 in time, optionally, an overflow port 126 is further provided on the side plate 120 of the chassis 100, the overflow port 126 is close to the first water level detector 710, and the lower edge of the overflow port 126 is flush with the upper surface of the bottom plate 110 of the chassis 100. In other words, the lower edge of the overflow port 126 is equivalent to the lowest overflow water level of the overflow port 126, and the lowest overflow water level is flush with the upper surface of the bottom plate 110, so that once water accumulates on the bottom plate 110, it can be discharged from the overflow port 126 in time, avoiding the accumulation of a lot of water near the chassis 100, and greatly improving the waterproof effect of the air conditioner.

[0068] In one embodiment, the electrical component further includes a second water level detector 720, which is installed in the electrical appliance accommodating area 106. The second water level detector 720 is spaced apart from the first water level detector 710 to detect a second water level in the electrical appliance accommodating area 106, wherein the second water level is higher than the first water level. The first water level detector 710 serves as a first water level defense line, and the second water level detector 720 serves as a second water level defense line. When the second water level detector 720 is working, the second water level detector 720 feeds back a second water level signal to the control device of the air conditioner, and the control device then receives the second water level signal to perform an alarm or drain water.

[0069] See also Figure 12 to Figure 14 The air conditioner further comprises an electrical protection cover 500 covering the upper end of the drain valve 400, the electrical protection cover 500 is configured with an insert 510, and the other end of the electrical protection cover 500 is configured with a fixing member 520; the chassis 100 is configured with an insert portion 118 (such as Fig. 9 ) and the fixing portion 119 (such as Fig.10 ), the insertion portion 118 is correspondingly inserted and connected with the insertion member 510, and the fixing portion 119 is correspondingly connected and fixed with the fixing member 520.

[0070] Specifically, the electrical protection cover 500 is used to cover electrical components such as the drain valve 400 to prevent water inside the air conditioner from dripping onto the electrical components, so as to prevent these electrical components from being damp and causing leakage or damage. The insertion portion 118 of the chassis 100 is provided with a socket for inserting the plug-in of the power supply protection cover 500. When installing the electrical protection cover 500, first insert the insertion part 510 of the electrical protection cover 500 into the socket of the insertion portion 118 of the chassis 100 to pre-position the electrical protection cover 500; then, the fixing part 520 of the electrical protection cover 500 is connected and fixed to the fixing part 119 of the chassis 100 by passing a connecting part (such as a screw), so that the electrical protection cover 500 is fixed to the chassis 100, and the installation operation is simple and fast, and the assembly efficiency is high.
