[0001] The present application belongs to the technical field of household appliances, and in particular relates to an air-conditioning outdoor unit and a kitchen air-conditioning system. Background Art

[0002] Water-cooled kitchen air conditioners use cooling water to remove heat from the pipeline. Small refrigeration equipment usually uses a shell and tube heat exchanger, which has the same function as the condenser of a conventional air conditioner outdoor unit. Conventional air conditioner outdoor units usually use air cooling to dissipate heat, while shell and tube heat exchangers use liquid cooling to dissipate heat. The hot water generated by the shell and tube heat exchanger during cooling can generally only be discharged, resulting in a serious waste of water resources. In related technologies, in order to reduce the waste of hot water after heat exchange, some water-cooled kitchen air conditioners introduce water tanks to store hot water for subsequent use by users.

[0042] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0043] The present application discloses an air-conditioning outdoor unit 100 .

[0044] Reference below Figure 1-Figure 5 An air conditioner outdoor unit 100 according to an embodiment of the present application is described.

[0045] In some embodiments, as Figure 1 and Figure 4 As shown, the air-conditioning outdoor unit 100 includes a compressor 110 , a water-cooled heat exchanger 120 and a regulating valve 130 .

[0046] The water-cooled heat exchanger 120 is the condenser of the entire kitchen air-conditioning system. The refrigerant inlet 123 of the water-cooled heat exchanger 120 is connected to the outlet of the compressor 110, and the water outlet 122 of the water-cooled heat exchanger 120 is used to be connected to the hot water faucet 200 and the sewer 300; the regulating valve 130 is suitable for being connected between the water outlet 122 of the water-cooled heat exchanger 120 and the sewer 300, and the regulating valve 130 is used to selectively connect the water outlet 122 of the water-cooled heat exchanger 120 and the sewer 300, and the regulating valve 130 is configured to be closed when the hot water faucet 200 is open.

[0047] The specific structure of the water-cooled heat exchanger 120 may include but is not limited to a shell-and-tube water-cooled heat exchanger, a shell-and-tube water-cooled heat exchanger, or a plate-type water-cooled heat exchanger, etc., which is not limited here.

[0048] For example, in some embodiments, Figure 5 As shown, the specific structure of the water-cooled heat exchanger 120 is a shell-and-tube type water-cooled heat exchanger.

[0049] The regulating valve 130 may include but is not limited to a solenoid valve, an electric valve or a common mechanical valve, etc., which is not limited here.

[0050] For example, in some embodiments, Figure 1-Figure 3 As shown, the regulating valve 130 is a common mechanical valve.

[0051] In actual implementation, Figure 1 As shown, low-temperature coolant can enter the water-cooled heat exchanger 120 through the water inlet 121. After heat exchange, high-temperature coolant can leave the water-cooled heat exchanger 120 through the water outlet 122. When the user needs to use hot water immediately, the user can directly open the hot water faucet 200. At this time, the water outlet 122 of the water-cooled heat exchanger 120 and the sewer 300 are in a non-conductive state, that is, the regulating valve 130 is closed, and hot water can flow directly from the water outlet 122 of the water-cooled heat exchanger 120 to the hot water faucet 200; when the user needs to store hot water, the user can close the drain of the sink and open the hot water faucet 200 to store the hot water in the sink for subsequent use; when the user does not need to use hot water, the water outlet 122 of the water-cooled heat exchanger 120 and the sewer 300 can be in a conductive state, that is, the regulating valve 130 is opened, and hot water can flow directly from the water outlet 122 of the water-cooled heat exchanger 120 to the sewer 300.

[0052] The air-conditioning outdoor unit 100 provided in the embodiment of the present application realizes the daily reuse of the high-temperature coolant after heat exchange through the setting of the above-mentioned regulating valve 130, in conjunction with the design of the connection relationship between the water outlet 122, the regulating valve 130, the hot water faucet 200 and the sewer 300, so as to facilitate users to use hot water to wash food or kitchen utensils. When the user enjoys the cold air of the kitchen air conditioner, hot water is available as soon as it is turned on. At the same time, when there is no need for hot water, it can be directly discharged through the sewer 300, significantly reducing the waste of water resources, thereby optimizing the user's sense of use and experience. In addition, hot water can be stored in the sink in advance and used directly when needed without installing a water tank, thereby reducing the volume of the air-conditioning outdoor unit 100, which is beneficial to the overall spatial layout of the kitchen air-conditioning system.

[0053] In some embodiments, the regulating valve 130 may be configured to open the water outlet 122 and the sewer 300 when the pressure difference exceeds a threshold.

[0054] The threshold value may be between 80 Kpa and 120 Kpa. Specifically, the threshold value may be 80 Kpa, 87.775 Kpa, 92.25 Kpa, 100 Kpa, 110.5 Kpa, 120 Kpa or other values ​​between 80 Kpa and 120 Kpa, which is not limited here.

[0055] It can be understood that the pressure difference is the difference in pressure on both sides of the regulating valve 130. The regulating valve 130 can selectively connect the water outlet 122 of the water-cooled heat exchanger 120 and the sewer 300 according to the size of the pressure difference. If the regulating valve 130 uses an electrically controlled valve, the regulating valve 130 may include but is not limited to a relief valve or a pressure regulating valve, etc. If the regulating valve 130 uses an ordinary mechanical valve, the regulating valve 130 may be provided with a pressure-sensitive structure. Specifically, the pressure-sensitive structure can change its own state according to the size of the pressure difference to change the open and closed state of the entire regulating valve 130.

[0056] In this embodiment, if Figure 1 As shown, when the user needs to use hot water immediately, the user can directly open the hot water faucet 200 to drive the hot water to flow upward to the hot water faucet 200, so that the water pressure on the side of the regulating valve 130 close to the hot and cold faucets is relatively small. At this time, the pressure difference does not exceed the threshold value, and the regulating valve 130 is closed; when the user does not use hot water for a long time, the hot water accumulated between the regulating valve 130 and the hot and cold faucets gradually increases, so that the water pressure on the side of the regulating valve 130 close to the hot and cold faucets gradually increases until the pressure difference exceeds the threshold value and the regulating valve 130 opens.

[0057] In other embodiments, the regulating valve 130 can also be configured to connect the water outlet 122 and the sewer 300 when the liquid level exceeds the target position. Specifically, a liquid level sensor can be set at a suitable position between the water outlet 122 of the water-cooled heat exchanger 120 and the outlet of the hot and cold faucets. When the liquid level sensor detects that the liquid level of the hot water accumulated between the regulating valve 130 and the hot and cold faucets exceeds the target position, the liquid level sensor can send a signal to control the regulating valve 130 to open.

[0058] The air-conditioning outdoor unit 100 provided in the embodiment of the present application, through the design of controlling the opening and closing state of the regulating valve 130 based on the pressure difference, improves the accuracy of switching the opening and closing states of the regulating valve 130 compared to manual control, while avoiding the risk of forgetting to turn the regulating valve 130 on and off due to human subjective factors. Compared with the solution of control based on liquid level or other parameters, it reduces the introduction of other devices and achieves cost control.

[0059] In some embodiments, as Figure 1-Figure 3 As shown, the regulating valve 130 may include a diaphragm, and the diaphragm may have a cutout 131 .

[0060] The material of the diaphragm may include but is not limited to silicone, polyurethane, chloroprene rubber or nitrile rubber, etc., which is not limited here.

[0061] For example, in some embodiments, the membrane is made of silicone.

[0062] like Figure 3 As shown, since common household water pipes are all round pipes, the shape of the diaphragm can preferably be a truncated cone.

[0063] In actual implementation, Figure 1-Figure 3 As shown, when the pressure difference on both sides of the diaphragm exceeds the threshold value, the hot water accumulated between the diaphragm and the hot and cold taps can flush open the slit 131 of the diaphragm, and the regulating valve 130 is in the open state. When the pressure difference on both sides of the diaphragm does not exceed the threshold value, the slit 131 of the diaphragm is closed, and the regulating valve 130 is in the closed state.

[0064] The air-conditioning outdoor unit 100 provided in the embodiment of the present application realizes the flow direction of hot water regulation based on pressure difference through the setting of the above-mentioned diaphragm combined with the design of the incision 131. Compared with the common solution of using an electric control valve, it prevents the electric control valve from getting stuck during the switching process, thereby improving the reliability of the regulating valve 130 and reducing manufacturing costs.

[0065] In some embodiments, as Figure 1-Figure 2 As shown, the cutout 131 may be a straight line or a plurality of intersecting straight lines.

[0066] The processing method of the incision 131 may include but is not limited to knife punching or laser cutting, etc., which is not limited here.

[0067] For example, in some embodiments, Figure 1-Figure 2 As shown, the cutout 131 is linear. In other words, the cutout 131 is in a straight line shape.

[0068] For example, in some other embodiments, the cutout 131 is in the shape of two intersecting straight lines. In other words, the shape of the cutout 131 is a cross.

[0069] For example, in some other embodiments, the cutout 131 is in the shape of three intersecting straight lines. In other words, the cutout 131 is in the shape of a cross.

[0070] It should be noted that in actual design, if the pressure difference threshold is large, a straight line shape can be selected when selecting the shape of the incision 131; if the pressure difference threshold is small, multiple intersecting straight lines can be selected when selecting the shape of the incision 131.

[0071] The air-conditioning outdoor unit 100 provided in the embodiment of the present application, through the shape design of the above-mentioned incision 131, is easy to process compared with the curved or serpentine type, thereby improving production efficiency. At the same time, different forms of linear incisions 131 can be matched according to actual needs, thereby increasing the structural diversity and flexibility of the control valve.

[0072] In some embodiments, as Figure 1 As shown, the air-conditioning outdoor unit 100 may further include: a three-way valve 140 , a first drain pipe 150 and a second drain pipe 160 .

[0073] The three-way valve 140 can be used to be connected to the water outlet 122, the hot water faucet 200 and the sewer 300 respectively; the inlet of the first drain pipe 150 can be connected to the three-way valve 140, and the outlet of the first drain pipe 150 can be used to be connected to the hot water faucet 200; the inlet of the second drain pipe 160 can be connected to the three-way valve 140, and the outlet of the second drain pipe 160 can be used to be connected to the sewer 300, and the regulating valve 130 can be installed between the inlet of the second drain pipe 160 and the three-way valve 140.

[0074] Among them, such as Figure 1As shown, based on the first drain pipe 150 being connected between the three-way valve 140 and the hot water faucet 200, considering that the water outflow from the hot water faucet 200 requires a certain speed, the first drain pipe 150 can use a water pipe with a smaller diameter, for example, the diameter of the first drain pipe 150 can use a water pipe with a diameter less than or equal to 6 centimeters; based on the second drain pipe 160 being connected between the three-way valve 140 and the sewer 300, considering the problem that the sewer 300 is easily blocked, the second drain pipe 160 can use a water pipe with a larger diameter, for example, the diameter of the first drain pipe 150 can use a water pipe with a diameter greater than 6 centimeters.

[0075] In this embodiment, if Figure 1 As shown, a connecting pipe 170 may be provided between the inlet of the second drain pipe 160 and the three-way valve 140, and the regulating valve 130 may be installed on the connecting pipe 170. During the assembly process, the regulating valve 130 may be installed on the connecting pipe 170 first, and then the connecting pipe 170, the three-way valve 140 and the second drain pipe 160 may be assembled. When the regulating valve 130 needs to be replaced, the regulating valve 130 can be easily removed by simply disassembling the connecting pipe 170.

[0076] In other embodiments, the regulating valve 130 may be installed on the three-way valve 140 . Specifically, the regulating valve 130 may be installed at the valve port of the three-way valve 140 that interfaces with the second drain pipe 160 .

[0077] In other embodiments, the regulating valve 130 may be installed on the second drain pipe 160 .

[0078] The air-conditioning outdoor unit 100 provided in the embodiment of the present application, through the arrangement of the above-mentioned three-way valve 140, the first drain pipe 150 and the second drain pipe 160, combined with the position design of the regulating valve 130, is convenient for installing and disassembling the regulating valve 130 compared to the solution of installing it on the three-way valve 140 or the second drain pipe 160, thereby improving the maintainability of the regulating valve 130.

[0079] In some embodiments, as Figure 1 and Figure 3 As shown, a connecting pipe 170 may be provided between the inlet of the second drain pipe 160 and the three-way valve 140, and the regulating valve 130 may be installed on the connecting pipe 170. The inner diameter of the connecting pipe 170 may gradually decrease from one end connected to the three-way valve 140 to the other end connected to the second drain pipe 160.

[0080] The connection method between the connecting pipe 170 and the regulating valve 130 may include, but is not limited to, interference fit, bolt connection, or bonding, which is not limited here.

[0081] It is understandable that the regulating valve is subjected to pressure from the hot water accumulated between the regulating valve and the hot water faucet for a long time. During long-term use, the regulating valve will inevitably move downward. Since the diameter of the second drain pipe is large, when the water pressure is too high, the regulating valve may be directly flushed into the second drain pipe, causing the entire water utilization system to fail.

[0082] When the inner diameter of the connecting pipe 170 gradually decreases from one end connected to the three-way valve 140 to the other end connected to the second drain pipe 160, the regulating valve 130 is prevented from continuously moving downward until it falls into the second drain pipe 160 during long-term use, thereby reducing the frequency of user maintenance of the regulating valve 130 and the second drain pipe 160, thereby extending the single cycle life of the regulating valve 130.

[0083] In some embodiments, as Figure 3 As shown, a limiting structure 171 may be provided in the connecting pipe 170 , and the regulating valve 130 may be arranged on a side of the limiting structure 171 close to the three-way valve 140 .

[0084] In this embodiment, if Figure 3 As shown, since the regulating valve 130 uses an elastic silicone diaphragm, the problem of the regulating valve 130 moving downward after deformation cannot be solved by simply relying on the design of the inner diameter of the connecting pipe 170. Therefore, a limiting structure 171 is further provided in the connecting pipe 170. The limiting structure 171 can be a boss structure protruding circumferentially along the inner wall of the connecting pipe 170. The regulating valve 130 can be overlapped on the limiting structure 171. When the water pressure on the upper side of the regulating valve 130 is large, the limiting structure 171 can block the downward movement of the regulating valve 130, thereby restricting the regulating valve 130 in the connecting pipe 170.

[0085] The air-conditioning outdoor unit 100 provided in the embodiment of the present application, through the setting of the above-mentioned limiting structure 171 and the inner diameter design of the connecting pipe 170, enhances the position limiting ability of the connecting pipe 170 on the regulating valve 130, and minimizes the probability of the regulating valve 130 being flushed into the second drain pipe 160 during long-term use, thereby further reducing the number of times the user maintains the regulating valve 130 and the second drain pipe 160.

[0086] In some embodiments, as Figure 1 As shown, the second drain pipe 160 may include at least one curved section.

[0087] In this embodiment, if Figure 1 As shown, the second drain pipe 160 may include two curved sections, wherein the bending directions of the two curved sections may be opposite.

[0088] In other embodiments, the second drain pipe 160 may include two curved sections, wherein the curved directions of the two curved sections may be the same.

[0089] In yet other embodiments, the second drain pipe 160 may include a curved section.

[0090] In yet other embodiments, the second drain pipe 160 may include three curved sections.

[0091] The air-conditioning outdoor unit 100 provided in the embodiment of the present application increases the flow resistance of hot water after entering the second drain pipe 160 through the provision of the above-mentioned at least one curved section, so that at least part of the liquid in the second drain pipe 160 forms a sealing effect on the sewer 300, preventing the odor in the sewer 300 from escaping, and at the same time reducing the probability of the odorous water in the sewer 300 flowing back.

[0092] In some embodiments, as Figure 1 As shown, the second drain pipe 160 may include a first curved section 161 , and the center of curvature of the first curved section 161 may be located above the first curved section 161 .

[0093] The curvature of the first curved section 161 may be 120°, 140°, or 180°, etc., which is not limited here.

[0094] In this embodiment, if Figure 1 As shown, the second drain pipe 160 may include a first curved section 161, and the bending direction of the first curved section 161 may be downward. Hot water is discharged from the water outlet 122 of the water-cooled heat exchanger 120 into the sewer 300 through the second drain pipe 160. Some liquid may remain in the first curved section 161. It is difficult for this part of liquid to cross the first curved section 161 and flow into the sewer 300 without external force, thereby forming a barrier to separate the gas environment on both sides and prevent the odor from the sewer 300 from rising into the first drain pipe 150.

[0095] The air-conditioning outdoor unit 100 provided in the embodiment of the present application realizes a liquid sealing effect on the sewer 300 through the setting of the above-mentioned first curved section 161, preventing the odor in the sewer 300 from directly rising into the hot water faucet 200, thereby enhancing the odor-blocking ability of the second drain pipe 160 as much as possible, and further optimizing the user's sense of use and experience.

[0096] In some embodiments, as Figure 1 As shown, the second drain pipe 160 may include a second curved section 162 , and the center of curvature of the second curved section 162 may be located below the second curved section 162 .

[0097] The curvature of the second curved section 162 may be 120°, 140°, or 180°, etc., which is not limited here.

[0098] In this embodiment, if Figure 1As shown, the second drain pipe 160 may include a second curved section 162, and the bending direction of the second curved section 162 may be upward. The stinky water in the sewer 300 is difficult to pass through the second curved section 162 and flow into the first drain pipe 150 or the water-cooled heat exchanger 120 without external force. In actual design, it can be used in conjunction with a check valve.

[0099] The air-conditioning outdoor unit 100 provided in the embodiment of the present application realizes the interception effect of the second drain pipe 160 on the backflow of foul water in the sewer 300 through the setting of the above-mentioned second curved section 162, preventing the dirty water in the sewer 300 from flowing back into other pipes, thereby enhancing the sewage discharge capacity of the second drain pipe 160 as much as possible, and thus optimizing the user's usage and experience.

[0100] In some embodiments, as Figure 4 As shown, the water-cooled heat exchanger 120 may surround the outside of the compressor 110 .

[0101] In this embodiment, if Figure 4 As shown, the air-conditioning outdoor unit 100 may include an outer shell, a water-cooled heat exchanger 120 and a compressor 110 may be installed in the outer shell, the water-cooled heat exchanger 120 may be a shell-and-tube type water-cooled heat exchanger, the compressor 110 may be arranged in the middle position of the shell, and the water-cooled heat exchanger 120 may be coiled around the outside of the compressor 110.

[0102] The water-cooled heat exchanger 120 may be wound around the outside of the compressor 110 one or more times, which is not limited here.

[0103] For example, in some embodiments, Figure 4 As shown, the water-cooled heat exchanger 120 may be wound three times around the outside of the compressor 110 .

[0104] The air-conditioning outdoor unit 100 provided in the embodiment of the present application significantly reduces the space occupied by the water-cooled heat exchanger 120 and the compressor 110 through the design of the arrangement of the above-mentioned water-cooled heat exchanger 120 and the compressor 110, and can leave more space in the shell for arranging other components, thereby maximizing space utilization and achieving an overall miniaturized and lightweight design.
