Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a three-dimensional air supply comfort air conditioner capable of defrosting. Background Art

[0002] The air conditioner is a widely used air conditioning equipment. Its main function is to regulate the temperature and humidity of the air. The cooling and heating principle of the air conditioner is to use the refrigerant to transfer heat through the indoor evaporator or outdoor condenser for heat exchange. During the air conditioning heating process, the temperature of the outdoor condenser is relatively low. In an environment with low outdoor temperature, frost will form on the outdoor condenser, affecting the normal use of the air conditioner.

[0003] In the related art, the air conditioner usually adopts the reverse cycle defrost mode, that is, the cooling mode defrost mode, and determines whether the outdoor heat exchanger needs to be defrosted through the fixed or small range changing compressor running time, outdoor coil temperature and outdoor heat exchange temperature difference. When the reverse cycle defrost mode is executed, the outdoor fan is controlled to stop running to increase the heat released by the outdoor heat exchanger, so that the frost on the outdoor heat exchanger melts, and then the frost on the outdoor heat exchanger is determined to be completely eliminated based on the defrost time and the outdoor coil temperature. The air conditioner exits the defrost mode and returns to the heating mode. The outdoor heat exchange temperature difference is the difference between the outdoor ambient temperature and the outdoor coil temperature. In the defrost mode, the heat exchanger of the indoor unit of the air conditioner will also absorb some heat from the room, causing the indoor temperature to drop, affecting the heating effect of the air conditioner, and then reducing the user experience and comfort.

[0004] Therefore we propose a defrostable three-dimensional air supply comfort air conditioner to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the related technology that the air conditioner usually adopts the reverse cycle defrost mode, that is, the cooling mode defrost mode, and determines whether the outdoor heat exchanger needs to be defrosted by the fixed or small range changing compressor running time, the outdoor coil temperature and the outdoor heat exchange temperature difference. When the reverse cycle defrost mode is executed, the outdoor fan is controlled to stop running to increase the heat released by the outdoor heat exchanger, so that the frost on the outdoor heat exchanger melts, and then the frost on the outdoor heat exchanger is determined to be completely eliminated according to the defrost time and the outdoor coil temperature. The air conditioner exits the defrost mode and returns to the heating mode, wherein the outdoor heat exchange temperature difference is the difference between the outdoor ambient temperature and the outdoor coil temperature, and in the defrost mode, the heat exchanger of the indoor unit of the air conditioner will also absorb part of the heat from the room, resulting in a decrease in the indoor temperature, affecting the heating effect of the air conditioner, and then reducing the user experience and comfort problem, and a defrostable three-dimensional air supply comfort air conditioner is proposed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By setting the turntable, the toggle plate, the vertical rod, the movable plate and the heating plate, the air conditioner does not need to be shut down for defrosting. When frost forms on the surface of the condenser, the heating plate moves to contact the fins on the condenser, and then the heating plate heats up and transfers the heat to the condenser to remove the frost on the surface of the condenser, making the heating effect of the air conditioner better and improving the user experience and comfort.

[0019] (2) By setting the upright column, motor, threaded rod, L-shaped lifting plate and cleaning brush, when the heating plate is defrosted and away from the condenser, the motor works to drive the L-shaped lifting plate and the cleaning brush to move vertically, so that the cleaning brush cleans the surface of the condenser, thereby removing the dust that may be attached to the surface of the condenser along with the frosted water droplets, thereby improving the heat absorption and heat dissipation performance of the condenser surface, and then improving the use effect of the air conditioner;

[0020] (3) By setting up a placement box, a temperature-sensitive element and a driving mechanism, the temperature of the condenser surface can be detected by the temperature-sensitive element. When the condenser surface reaches a low temperature at which frost forms, the temperature-sensitive element shrinks and the driving mechanism drives the heating plate to fit the condenser to achieve defrosting. After the condenser surface warms up, the temperature-sensitive element expands and drives the heating plate away from the condenser, so that the heating plate no longer fits the condenser, thereby avoiding affecting the condenser operation when fitting. The cleaning brush can also be used for cleaning, and the defrosting operation can be automatically achieved without setting up an additional driving source. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example

[0033] See also Figure 1 - Figure 8 As shown, a defrostable three-dimensional air supply comfort air conditioner comprises an air conditioner outer casing 1, a condenser 2 is arranged inside the air conditioner outer casing 1, a placement box 3 is arranged inside the left rear end of the air conditioner outer casing 1, wherein the placement box 3 is a heat preservation box, which can maintain the temperature inside the box body to prevent the external temperature from affecting the operation of the components inside the box body, a temperature sensitive element 4 is arranged inside the placement box 3, the upper end of the temperature sensitive element 4 is connected with a heat transfer tube 5 through a heat conduction plate 37, and a contact tube 6 is arranged on the upper end of the heat transfer tube 5, the front end of the contact tube 6 abuts against the side wall of the upper end of the condenser 2, so that the contact tube 6 is in direct contact with the condenser 2, and then when frost forms on the surface of the condenser 2, it means that the temperature at the condenser 2 is relatively low, and the heat at the temperature sensitive element 4 will be transferred to the condenser 2 along the heat transfer tube 5, and the condenser 2 is continuously cooled, and under the continuous heat transfer of the heat transfer tube 5, the temperature at the temperature sensitive element 4 is equal to the temperature at the condenser 2;

[0034] It should be noted that the temperature sensitive element 4 can be made of materials such as copper, aluminum, iron, nickel and metal alloys. These metals have moderate thermal expansion coefficients and are easy to process and manufacture. Metals and their alloys are common temperature sensitive materials because they have good electrical conductivity, thermal conductivity and mechanical properties. When the temperature changes, the metal will expand and contract, thereby generating pressure or displacement, which in turn enables the temperature sensitive element 4 to absorb or release heat through the heat conducting plate 37, the heat conduction tube 5 and the contact tube 6, thereby causing thermal expansion and contraction.

[0035] The front end of the temperature-sensitive element 4 is provided with a driving mechanism, which includes a piston rod 7, the rear end of the piston rod 7 is connected to the front end of the temperature-sensitive element 4, the front end of the piston rod 7 penetrates the placement box 3 and is connected with a toothed plate 8, the right side of the toothed plate 8 is meshedly connected with a driven gear 10, a rotating rod 11 is provided in the middle of the driven gear 10, a large gear 12 is provided on the circumferential surface of the upper part of the rotating rod 11, the rear end of the large gear 12 is meshedly connected with a transmission gear 13, the rear end of the transmission gear 13 is meshedly connected with a pinion 15, the transmission gear 13 transmits between the large gear 12 and the pinion 15, so that the large gear 12 rotates and can synchronously drive the pinion 15 to rotate, a rotating rod 3 16 is provided in the middle of the pinion 15, wherein the design of the large gear 12 and the pinion 15 enables the toothed plate 8 to move a short distance, and can drive the pinion 15 to rotate greatly through the large gear 12;

[0036] It should be noted that the initial state of the temperature-sensitive element 4 is at normal temperature. At this time, the temperature-sensitive element 4 in the state shown in the figure is in a cold contraction state, so the temperature on the surface of the condenser 2 is at a low temperature that can frost. Therefore, the temperature-sensitive element 4 transfers heat to the condenser 2 through the heat conduction plate 37 and the heat conduction tube 5, so that the temperature at the temperature-sensitive element 4 is the same as the temperature on the surface of the condenser 2, thereby driving the tooth plate 8 to move backward.

[0037] A rotating rod 2 14 is provided at the lower end of the transmission gear 13, and the lower ends of the rotating rod 1 11, the rotating rod 2 14 and the rotating rod 3 16 are all rotatably mounted on the inner bottom of the air conditioner outer housing 1, so that the rotating rod 1 11, the rotating rod 2 14 and the rotating rod 3 16 can respectively support the large gear 12, the transmission gear 13 and the small gear 15 without affecting the rotation of the large gear 12, the transmission gear 13 and the small gear 15. A moving groove 38 is opened inside the placement box 3, and the rear end of the piston rod 7 is arranged inside the moving groove 38. The temperature-sensitive element 4 and the heat-conducting plate 37 are both arranged inside the rear side of the placement box 3. The upper part of the heat-conducting tube 5 is fixed to the rear inner wall of the air-conditioning outer casing 1 by a fixing block 39, which can fix the heat-conducting tube 5 to prevent the heat-conducting tube 5 from falling or shaking and hitting objects such as the turntable 17. The setting of the movable groove 38 provides a space for the temperature-sensitive element 4 to expand and contract with heat, and at the same time provides a space for the piston rod 7 to move forward and backward, so that the temperature-sensitive element 4 can expand and contract with heat smoothly, thereby driving the piston rod 7 to move forward and backward;

[0038] It should be noted that the surfaces of the heat transfer tube 5 and the contact tube 6 are wrapped with thermal insulation cotton, so that the heat transfer tube 5 will not be consumed in the middle when transferring heat, and the temperature at the temperature sensitive element 4 can be the same as the temperature at the condenser 2.

[0039] The front end of the driving mechanism is provided with a pushing mechanism, which includes a turntable 17. The upper end of the rotating rod 3 16 is fixedly connected to the middle of the lower surface of the turntable 17, so that the rotating rod 3 16 can drive the turntable 17 to rotate. A toggle plate 18 is fixedly installed on the right side of the upper surface of the turntable 17. A vertical rod 20 is inserted into the right end of the toggle plate 18. A moving plate 21 is provided at the lower end of the vertical rod 20. A heating plate 22 is provided at the front end of the moving plate 21. The front end of the heating plate 22 abuts against the rear side of the lower surface of the condenser 2. When the working surface of the heating plate 22 generates heat, the fins on the condenser 2 can smoothly conduct the heat to the inside of the condenser tube, so that the surface temperature of the condenser 2 rises, and then the frost on the surface of the condenser 2 is removed. A movable groove 19 is provided inside the right side of the toggle plate 18, and the upper end of the vertical rod 20 is inserted into the inside of the movable groove 19. The setting of the movable groove 19 enables the vertical rod 20 to move inside the movable groove 19 when the toggle plate 18 rotates, and then smoothly drives the vertical rod 20 to move horizontally forward and backward;

[0040] It should be noted that the design of the heating plate 22 being located at the bottom is because the heat will be dissipated upward, so that the heat generated by the heating plate 22 can be utilized by the condenser 2 to the maximum extent. At the same time, the liquid inside the condenser 2 is also designed to flow from bottom to top, so that when the condenser 2 absorbs heat, it will continue to flow upward, thereby completely consuming the heat, achieving rapid defrosting, and reducing resource loss.

[0041] A baffle 9 is provided at the front end of the tooth plate 8, and the rear end of the baffle 9 abuts against the front end of the driven gear 10. The setting of the baffle 9 can limit the distance that the tooth plate 8 moves backward, so as to prevent the tooth plate 8 from moving backward too much, causing the heating plate 22 to move forward too much, squeezing the condenser 2, and causing damage to the heating plate 22 and the condenser 2;

[0042] A tooth plate 25 is provided at the upper end of the vertical rod 20, and the tooth plate 25 is located above the toggle plate 18, so that when the toggle plate 18 moves, it will not contact the tooth plate 25, thereby avoiding collision and jamming. The upper end of the tooth plate 25 is meshed with a driven gear 26, and a rotating rod 4 27 is provided in the middle of the driven gear 26. The front and rear ends of the rotating rod 4 27 are respectively rotatably mounted on the left inner wall and the rear inner wall of the air-conditioning outer unit housing 1. The upper end of the driven gear 26 is meshed with a tooth plate 3 28. The setting of the rotating rod 4 27 can limit the driven gear 26 without affecting the rotation of the driven gear 26, so that when the tooth plate 25 moves horizontally, the driven gear 26 can drive the tooth plate 3 28 to move horizontally. The front end of the upper surface of the tooth plate 3 28 is provided with a mounting plate 31, and the middle of the upper surface of the mounting plate 31 is provided. There is a column 32, and a motor 33 is arranged on the upper surface of the column 32. The motor 33 is a small motor and can be stably and conveniently installed on the column 32. The power output end of the motor 33 is connected to a threaded rod 34 through a coupling transmission. The threaded rod 34 is rotatably installed inside the column 32, and an L-shaped lifting plate 35 is arranged on the circumferential surface of the threaded rod 34. A lifting groove is opened at the front end of the column 32, and the rear end of the L-shaped lifting plate 35 is arranged inside the lifting groove and located at the uppermost end of the lifting groove. The setting of the lifting groove provides the L-shaped lifting plate 35 with a movable space, so that the L-shaped lifting plate 35 can move smoothly in the vertical direction. A cleaning brush 36 is arranged at the lower end of the L-shaped lifting plate 35, and the rear side of the cleaning brush 36 does not contact the front side of the mounting plate 31, so that the L-shaped lifting plate 35 can smoothly drive the cleaning brush 36 to move vertically;

[0043] It should be noted that the condenser 2, heating plate 22 and cleaning brush 36 are all L-shaped in design, so that the condenser 2 can have a larger contact surface with the air conditioner, thereby improving the performance of the air conditioner, and also allowing the heating plate 22 and the cleaning brush 36 to fit smoothly with the condenser 2, facilitating heating, defrosting and cleaning.

[0044] A positioning groove 24 is provided inside the movable plate 21, and a positioning rod 23 is inserted inside the positioning groove 24. The setting of the positioning groove 24 provides a plugging space for the positioning rod 23, so that the movable plate 21 can stably move horizontally on the positioning rod 23. The tooth plates 25 and 3 28 are both provided with positioning grooves 29, and a positioning rod 2 30 is inserted inside the positioning grooves 29. The setting of the positioning grooves 29 provides a plugging space for the positioning rod 2 30, so that the tooth plates 25 and 3 28 can stably move horizontally on the positioning rod 2 30. The rear ends of the positioning rod 1 23 and the two positioning rods 2 30 are rotatably mounted on the rear inner wall of the air conditioner outer housing 1, and the positioning rod 1 23 and the two positioning rods 2 30 are all on the same vertical plane;

[0045] It should be noted that the positioning rod 1 23 and the positioning rod 2 30 are on the same horizontal plane as the diagonal line of the air-conditioning outdoor unit casing 1, and then when the toggle plate 18 drives the vertical rod 20 to move, the vertical rod 20 can drive the movable plate 21 and the heating plate 22 to move horizontally on the positioning rod 1 23, and then the front side of the heating plate 22 is integrally fitted with the condenser 2, or as a whole away from the condenser 2, to prevent the heating plate 22 from offsetting and colliding with the condenser 2 and damaging the condenser 2.

[0046] A water collecting trough 40 is provided on the inner bottom wall of the air-conditioning outdoor unit casing 1, and several groups of water collecting troughs 40 are arranged in a horizontal array in front and behind, and are located below the condenser 2. The interior of the water collecting trough 40 is designed to be higher on the left and lower on the right. A drainage trough 41 is provided on the right bottom of the air-conditioning outdoor unit casing 1, and the drainage trough 41 is connected to the right ends of several groups of water collecting troughs 40. The setting of the water collecting trough 40 can enable the water droplets formed to drip into the water collecting trough 40 and accumulate after the heating plate 22 removes the frost on the surface of the condenser 2. Then, the water flows to the right to the drainage trough 41 through the high left and low right part of the water collecting trough 40, and then flows to the outlet pipe through the drainage trough 41 for discharge, thereby preventing the water from remaining in the air-conditioning outdoor unit casing 1 and freezing, affecting the use of the air-conditioning outdoor unit casing 1.

[0047] When the present invention is in use, when the air conditioner interior unit is heating, the surface temperature of the condenser 2 inside the air conditioner exterior unit housing 1 will decrease, and then because the outdoor temperature is relatively low, the surface of the condenser 2 will frost after it drops below a certain temperature. When the surface temperature of the condenser 2 drops to a low temperature at which frost will form, the heat conducting plate 37, the heat conducting tube 5 and the contact tube 6 conduct the temperature of the temperature sensitive element 4 to the condenser 2, so that the temperature of the temperature sensitive element 4 is the same as the temperature of the condenser 2, and then the temperature sensitive element 4 contracts, driving the piston rod 7 and the tooth plate 8 to move backward;

[0048] The toothed plate 18 moves backward to drive the driven gear 10, the rotating rod 11 and the large gear 12 to rotate. The large gear 12 drives the small gear 15 and the rotating rod 3 16 to rotate through the transmission gear 13, so that the rotating rod 3 16 drives the rotating disk 17 to rotate. The rotation of the rotating disk 17 drives the toggle plate 18 to rotate forward. The toggle plate 18 pushes the vertical rod 20, the movable plate 21 and the heating plate 22 to move forward, so that the heating plate 22 fits the condenser 2. Then the heating plate 22 works to heat, and the condenser 2 absorbs the heat to itself through the fins, thereby removing the frost on the surface of the condenser 2. After the surface temperature of the condenser 2 rises, the heat is transferred back to the temperature-sensitive element 4 through the heat transfer tube 5, so that the temperature-sensitive element 4 expands, and then drives the piston rod 7 and the toothed plate 18 to move forward, so that the rotating disk 17 drives the toggle plate 18 to rotate in the opposite direction, and then drives the vertical rod 20, the movable plate 21 and the heating plate 22 away from the condenser 2, and at this time, the heating plate 22 is turned off at the same time;

[0049] When the heating plate 22 moves in the direction away from the condenser 2, the vertical rod 20 drives the tooth plate 25 to move backward, and the tooth plate 25 drives the tooth plate 3 28 to move forward through the driven gear 2 26, and the tooth plate 3 28 drives the mounting plate 31 and the column 32 to move forward, so that the front end of the cleaning brush 36 abuts against the surface of the condenser 2, and then the motor 33 is started, and the motor 33 drives the threaded rod 34 to rotate, so that the L-shaped lifting plate 35 drives the cleaning brush 36 to move vertically downward, and the cleaning brush 36 cleans the surface of the condenser 2, and cleans the water droplets attached to the surface of the condenser 2. At the same time, the dust attached to the surface of the condenser 2 will be cleaned along with the water droplets, thereby improving the working efficiency of the condenser 2. Then, the motor 33 drives the threaded rod 34 to rotate in the opposite direction, so that the L-shaped lifting plate 35 drives the cleaning brush 36 to reset upward, so as to avoid the heating plate 22 moving forward and touching the cleaning brush 36 when the heating plate 22 needs to defrost next time.

[0050] Then the water droplets carrying dust fall into the water collecting trough 40 and accumulate. Then, the collected water flow is guided to the right to the drainage trough 41 through the left-high and right-low guidance inside the water collecting trough 40. Then, it flows backward through the drainage trough 41 to be discharged from the water outlet pipe, so as to prevent the water droplets from remaining in the air-conditioning outdoor unit casing 1 and freezing to affect the use of the air-conditioning outdoor unit casing 1.
