Fig. 1 to 14 are drawings illustrating an air conditioner according to the present invention. The present invention provides an air conditioner capable of cooling or heating an indoor environment to adjust the temperature of the indoor environment. The air conditioner adopts a new drain valve mounting mode, can reduce the corrosion condition that appears by using the screw, improves the stability of drain valve installation.

Referring to fig. 1, in an 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 base plate 100, a casing installed on the base plate 100, an indoor side heat exchanger, and an outdoor side heat exchanger. The shell is internally provided with an outdoor heat exchange chamber and an indoor heat exchange chamber positioned above the outdoor heat exchange chamber; the outdoor heat exchanger is arranged in the outdoor heat exchange chamber; the indoor side heat exchanger is installed in the indoor heat exchange chamber.

When the mobile air conditioner is used for refrigerating, air in an indoor environment enters the indoor heat exchange chamber, cold air is formed after heat exchange is carried out through the indoor side heat exchanger, and then the cold air is blown out to the indoor environment, so that the indoor environment is refrigerated; meanwhile, air in the indoor environment or the outdoor environment enters the outdoor heat exchange chamber, heat is formed after heat exchange is carried out by the outdoor heat exchanger, and the hot air is finally exhausted to the outdoor through the exhaust pipe.

Referring to fig. 1 and 2, in an embodiment, the air conditioner includes a base plate 100 and a drain valve 400, the base plate 100 is configured with a water receiving tank 101 and a water outlet 102 communicated with the water receiving tank 101; the drain valve 400 is mounted on the chassis 100, and the drain valve 400 includes a valve seat 410 and a valve rod 420 connected to the valve seat 410, wherein the valve rod 420 is movable relative to the valve seat 410 to open and close the water outlet 102. Wherein, the chassis 100 is further configured with a valve groove 170 (as shown in fig. 7 and 8) for installing the valve seat 410, a limiting member 173 is configured around the valve groove 170, and the limiting member 173 is adapted to fix the valve seat 410 in the valve groove 170.

Specifically, the water receiving tank 101 of the base plate 100 may be used to store condensed water generated by the heat exchanging component, and the base plate 100 may form a water outlet 102 at the bottom of the water receiving tank 101, so that water in the water receiving tank 101 is directly discharged from the water outlet 102. Or, the chassis 100 forms a water outlet 102 at one side of the water receiving tank 101, and a drainage channel (as shown by a dotted arrow in fig. 4) is arranged between the water outlet 102 and the water receiving tank 101, so that water in the water receiving tank 101 flows through the drainage channel and flows through the water outlet 102, and is finally discharged from the water outlet 102. The latter embodiment is specifically adopted here.

The drain valve 400 is disposed opposite to the water outlet 102, and the drain valve 400 can open and close the water outlet 102. The valve seat 410 of the drain valve 400 is formed at its top surface with a connection terminal 412, and a driving shaft 411 is extended from an end of the valve seat 410 adjacent 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 rod 420 to move towards the water outlet 102 through the driving shaft 411, so that the valve rod 420 blocks the water outlet 102, and the water outlet 102 is closed; when it is required to open the water outlet 102, the valve seat 410 of the drain valve 400 moves the valve stem 420 in reverse by the driving shaft 411, so that the valve stem 420 is withdrawn from the water outlet 102, thereby opening the water outlet 102.

When the drain valve 400 is installed, the valve seat 410 of the drain valve 400 is installed in the valve groove 170, and the valve rod 420 of the drain valve 400 is aligned with the water outlet 102; the valve seat 410 of the drain valve 400 is then defined within the valve spool 170 by the retainer 173 around the periphery of the valve spool 170, thereby securing the drain valve 400. For the structure type of the retaining member 173, the retaining member 173 is a non-screw structure, for example, the retaining member 173 may be a retaining clip, an elastic pressing sheet, a self-locking band, or the like. The number of the stoppers 173 may be one or two or more, which may be designed according to the size of the drain valve 400. The specific shape and structure of the stopper 173 will be described in detail later.

According to the technical scheme of the invention, the valve groove 170 for installing the water drain valve 400 is formed on the base plate 100, the limiting piece 173 is formed on the periphery of the valve groove 170, and the water drain valve 400 is limited in the valve groove 170 by the limiting piece 173, so that the water drain valve 400 is not required to be fixed by screws, the use of the screws is reduced, the corrosion condition caused by the use of the screws is reduced, and the installation stability of the water drain valve 400 is improved.

Referring to fig. 3 and 4, in an embodiment, the chassis 100 is further configured with a drainage channel 180 spaced apart from the valve channel 170, and an end of the drainage channel 180 away from the valve channel 170 is provided with a water outlet 102 (see fig. 7 and 8), and the water outlet 102 connects the drainage channel 180 with the water receiving channel 101; the valve stem 420 of the drain valve 400 is located in the drain tank 180.

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

Referring to fig. 8 and 11, in order to facilitate the drainage of the drainage groove 180, a drainage connection pipe 130 is formed on the lower surface of the base pan 100, one end of the drainage connection pipe 130 communicates with the drainage groove 180, and the other end of the drainage connection pipe 130 is provided with a water plug 300. The water plug 300 includes a plug head 310 inserted into the drain opening of the drain adapter 130, and a fixing strip 320 connected to the plug head 310, wherein the fixing strip 320 is fixedly connected to the chassis 100. After the plug head 310 of the water plug 300 is pulled out of the drainage connection pipe 130, the water in the drainage groove 180 is drained outwards through the drainage connection pipe 130; at this time, since the fixing strip 320 of the water plug 300 is fixed to the chassis 100, the water plug 300 is not easily lost. After the drainage is finished, the water plug 300 is inserted into the drainage connection pipe 130 to plug the drainage connection pipe 130, so as to avoid water leakage.

It is considered that, when the valve seat 410 of the drain valve 400 drives the valve rod 420 to move, the valve rod 420 may be laterally offset, so that the valve rod 420 is not easily corresponding to the water outlet 102, thereby increasing the difficulty of completely opening or closing the water outlet 102. To avoid this, guide ribs 181 are optionally formed at opposite sides of the drain groove 180, 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.

After installing drain valve 400, two direction muscle 181 are located valve rod 420's relative both sides to being injectd valve rod 420 in the guide way between two direction muscle 181, making valve rod 420 can only be in the same direction as the extending direction activity along direction muscle 181, difficult emergence side direction skew, thereby realizing valve rod 420 and the accurate counterpoint of delivery port 102, effectively reducing the degree of difficulty of opening or closing delivery port 102 completely.

Referring to fig. 5 and 6, in an embodiment, the chassis 100 is configured with a plurality of limiting members 173 around the valve slot 170, so as to fix the drain valve 400 through the plurality of limiting members 173, and the specific arrangement positions of the limiting members 173 may be designed according to the shape and structure of the valve slot 170. Here, the valve housing 170 may have a front wall plate 171 opposite to the water outlet 102 and side wall plates 172 extending rearward from both sides of the front wall plate 171, and stoppers 173 may be formed on both side wall plates 172, and the stoppers 173 on both side wall plates 172 may be respectively engaged with both opposite sides of the valve housing 410 to fix the valve housing 410 to the valve housing 170.

Specifically, a plurality of stoppers 173 are formed on both side wall plates 172 of the valve spool 170, and the stoppers 173 on each side wall plate 172 are arranged at intervals along the length direction of the valve spool 170. The stoppers 173 on the two side wall plates 172 are respectively engaged with opposite sides of the valve seat 410, thereby stably fixing the valve seat 410 in the valve groove 170 and improving the stability of the installation of the valve seat 410. It should be noted that the limiting member 173 preferably has a certain elasticity so as to facilitate the application of an external force to elastically deform the limiting member 173 to disassemble and assemble the valve seat 410.

Referring to fig. 5 and 6, optionally, the retainer 173 includes a retaining arm 1731 protruding upward from the upper edge of the sidewall plate 172, and a hook 1732 extending upward from the upper end of the retaining arm 1731 toward the upper side of the valve slot 170, and the retainer 173 is retained by the hook 1732 and the side portion of the valve seat 410. 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 be laterally removed; the hook 1732 of the retainer 173 limits the upward movement of the valve seat 410, so that the valve seat 410 cannot be removed upward.

Referring to fig. 7 and 8, in an embodiment, the rear end of the valve spool 170, which is far away from the front wall 171, is formed with an opening, which may prevent the periphery of the valve spool 170 from forming a closed structure, and heat generated by the valve seat 410 may be dissipated from the opening during the operation of the drain valve 400. Alternatively, water dripping into the valve spool 170 may be discharged through the opening to prevent water accumulation and thus leakage of electricity from the drain valve 400.

In order to prevent the valve seat 410 of the drain valve 400 from being removed from the opening of the valve spool 170, a stopper 174 is formed at the opening between the two side wall plates 172 of the valve spool 170, and the stopper 174 is adapted to abut against the rear end of the valve seat 410. The valve seat 410 is blocked by the stop post 174 and is difficult to fall out of the opening of the valve spool 170.

Further, a breaking notch 125 may be formed on the side plate 120 of the chassis 100 close to the opening of the valve spool 170, and the breaking notch 125 corresponds to the opening of the valve spool 170; the rear ends of the two side wall plates 172 of the valve spool 170 extend toward the off-position notch 125 to form extension plates 103, and a channel 104 for communicating the opening with the off-position notch 125 is formed between the two extension plates 103.

Specifically, the tray 100 may be formed with a cut-off notch 125 during the molding process, and the cut-off notch 125 cuts off the side plate 120 to facilitate the molding process of the tray 100. The position-breaking notch 125 is correspondingly communicated with the opening of the valve groove 170 through the channel 104 between the two extension plates 103, so that a heat dissipation channel or a drainage channel is formed. That is, the heat generated by the valve seat 410 can be dissipated from the opening of the valve spool 170 to the outside of the mobile air conditioner through the channel 104 and the position-breaking notch 125, so as to prevent the valve spool 170 from being burnt out due to the accumulation of a large amount of heat. Similarly, if water is present in the valve spool 170, the water can be discharged from the opening of the valve spool 170 to the outside of the mobile air conditioner through the passage 104 and the cut-off 125, thereby preventing the valve spool 170 from leaking electricity to the valve seat 410 due to water accumulation.

Referring to fig. 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 abutted together, the contact area between the two is large, heat generated by the valve seat 410 is easily accumulated at the position where the two contact, so that the heat is not easily dissipated, and there is a risk that the valve seat 410 is burned out due to the temperature rise.

In order to solve the above problem, a plurality of supporting protrusions 176 are protruded from the bottom surface of the valve spool 170, and the supporting protrusions 176 are supported on the bottom surface of the valve seat 410 to space the bottom surface of the valve seat 410 apart from the bottom surface of the valve spool 170. This allows a first gap to be formed between the bottom surface of the valve seat 410 and the bottom surface of the valve spool 170 at an interval, which forms a good heat dissipation path to help the drain valve 400 dissipate heat outward. It should be noted that the height of the supporting protrusion 176 protruding from the bottom surface of the valve slot 170 should be smaller than the height of the position-limiting post 174 protruding from the bottom surface of the valve slot 170, so as to ensure that the position-limiting post 174 can be abutted against the rear end of the valve seat 410.

Similarly, if the side surface of the valve seat 410 and the side wall plate 172 of the valve spool 170 are abutted together, the contact area between the two is large, and heat generated by the valve seat 410 is easily accumulated at the position where the two are contacted, so that the heat is not easily dissipated, and there is a risk that the valve seat 410 is burned out due to the temperature rise. To solve this problem, positioning protrusions 175 are protruded from inner wall surfaces of the two side wall plates 172 of the valve spool 170, the positioning protrusions 175 extend forward from rear ends of the side wall plates 172 to the front wall plate 171, and the positioning protrusions 175 on the two side wall plates 172 are fitted against both side surfaces of the valve seat 410 to space apart the side surfaces of the valve seat 410 and the side wall plates 172.

Specifically, when the valve seat 410 is mounted to the valve spool 170, the positioning protrusions 175 of the two side wall plates 172 of the valve spool 170 respectively abut against both side surfaces of the valve seat 410, similarly to the two positioning protrusions 175 holding the fixed valve seat 410. The valve seat 410 is blocked by the positioning protrusion 175, and both side surfaces of the valve seat 410 cannot contact the side wall plate 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 plate 172 at an interval, and the second gap and the first gap are communicated to form a good heat dissipation channel, thereby greatly improving the heat dissipation effect of the drain valve 400.

Referring to fig. 7 and 11, according to any of the above embodiments, the chassis 100 is configured with a water receiving tank 101 and a mounting position 105 for mounting a compressor; the chassis 100 is configured between the water receiving tank 101 and the mounting position 105 to form an electrical appliance accommodating area 106, and the electrical appliance accommodating area 106 is suitable for accommodating and mounting electrical appliance components; the drain valve 400 is located in the appliance receiving region 106.

Specifically, the water receiving tank 101 on the base plate 100 is correspondingly located below the outdoor heat exchanger, so as to be suitable for receiving the condensed water generated by the outdoor heat exchanger. Generally, a large empty space is formed between the water receiving tank 101 and the installation location 105 for installing the compressor, so that the empty space can be configured to form an electrical appliance accommodating area 106 for accommodating and installing electrical appliance components, thereby making full use of the internal space of the mobile air conditioner and effectively standardizing the distribution of internal components of the mobile air conditioner.

Referring to fig. 7 and 11, in an embodiment, the electrical component further includes a first water level detector 710, and the first water level detector 710 is installed in the electrical container 106 and adapted to detect a first water level of the electrical container 106 and feed back a first water level signal to a control device of the air conditioner, so that the control device receives the first water level signal to alarm or discharge water.

In order to ensure that the bottom plate 100 can discharge water on the bottom plate 110 in time, an overflow port 126 is optionally further formed in the side plate 120 of the bottom plate 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 bottom plate 100. That is, 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 is accumulated on the bottom plate 110, the water can be discharged from the overflow port 126 in time, the chassis 100 is prevented from accumulating more water nearby, and the waterproof effect of the air conditioner is greatly improved.

In an embodiment, the electrical component further includes a second water level detector 720, the second water level detector 720 is installed in the electrical container 106, and the second water level detector 720 and the first water level detector 710 are spaced apart from each other to be suitable for detecting a second water level of the electrical container 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 works, 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 receives the second water level signal to alarm or drain water.

Referring to fig. 12 to 14, the air conditioner further includes an electric appliance protective cover 500 covering the upper end of the drain valve 400, the electric appliance protective cover 500 is configured with an insert 510, and the other end of the electric appliance protective cover 500 is configured with a fixing member 520; the chassis 100 is provided with an inserting part 118 (as shown in fig. 9) and a fixing part 119 (as shown in fig. 10), wherein the inserting part 118 is correspondingly inserted and connected with the inserting piece 510, and the fixing part 119 is correspondingly connected and fixed with the fixing piece 520.

Specifically, the appliance protecting cover 500 is used to cover electrical components such as the drain valve 400, etc., to prevent water inside the air conditioner from dropping onto the electrical components, thereby preventing the electrical components from being affected with moisture and causing leakage or damage. The insertion portion 118 of the chassis 100 is opened with a jack for inserting the connector of the connector cover 500. When the electrical apparatus protecting cover 500 is installed, the insert 510 of the electrical apparatus protecting cover 500 is inserted into the insertion hole of the insertion part 118 of the chassis 100 to realize the pre-positioning of the electrical apparatus protecting cover 500; then, the fixing part 520 of the protecting cover 500 of the electrical appliance is fixedly connected with the fixing part 119 of the chassis 100 by a penetrating connecting part (such as a screw), so that the protecting cover 500 of the electrical appliance is fixed on the chassis 100, the installation operation is simple and rapid, and the assembly efficiency is high. It should be noted that the connecting member may be a screw, and the fixing portion 119 of the chassis 100 is a screw column.

Obviously, the electric components covered by the appliance protective cover 500 are not limited to the drain valve 400.
