Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to air conditioning equipment and a tea table. Background Technology

[0002] Many shops in cities design outdoor open-plan seating areas for customers. These spaces create a relaxing environment and offer several advantages over indoor seating, such as access to fresh air, open space, and reduced noise from other customers. Therefore, some customers prefer outdoor seating. However, weather conditions, such as hot, cold, or rainy days, can sometimes prevent customers from choosing these seats, resulting in low occupancy rates and impacting the shop's business.

[0003] Therefore, if a product could provide a comfortable environment for open spaces in hot, cold, and rainy weather, increase user seating options, and improve customer experience, it could solve the problem of low occupancy rates in open spaces caused by weather factors, thereby increasing store revenue. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, on the one hand, this utility model provides an air conditioning device that can provide a comfortable environment for open-space seating under different weather conditions such as hot, cold and rainy days.

[0005] On the other hand, this utility model also proposes a tea table with the aforementioned air conditioning equipment.

[0006] The technical solution adopted by this utility model is to design an air conditioning equipment, including a heat exchange module. The heat exchange module is equipped with a heat exchanger, a heat exchange fan, and an upper air outlet and a lower air outlet located on the upper and lower sides of the heat exchanger. A fan umbrella is provided above the heat exchange module. The fan umbrella includes an umbrella cover, an air supply pipe, and an air supply power device installed on the air supply pipe. One end of the air supply pipe corresponds to the center below the umbrella cover, and the other end is connected to the upper air outlet and the lower air outlet respectively through two control valves.

[0007] In some embodiments, the heat exchange module has several upper air inlets arranged circumferentially on its upper part, and several lower air inlets corresponding to each of the upper air inlets are arranged on its lower part.

[0008] In some embodiments, a rainwater detector is provided on the umbrella cover, and the air supply power device controls its operating status based on the detection information of the rainwater detector.

[0009] In some embodiments, both the upper air inlet and the lower air inlet are provided with air sweeping plates, which are controlled to rotate by a rotating device. When the air sweeping plates are opened, the upper air inlet faces upward and the lower air inlet faces downward.

[0010] In some embodiments, the canopy is supported on top of the heat exchange module via the air supply duct.

[0011] In some embodiments, the heat exchange module is provided with a rotating base that allows the heat exchange module to rotate about a vertical axis.

[0012] In some embodiments, the axis of rotation of the rotating base is coaxial with that of the umbrella canopy.

[0013] A tea table, on which the aforementioned air conditioning equipment is installed.

[0014] In some embodiments, the heat dissipation module is located in the center of the tabletop of the tea table. The heat dissipation module is a prism, and each side of the prism is provided with the upper air vent and the lower air vent.

[0015] In some embodiments, the tea table is provided with multiple control switches, and different control switches control the opening and closing state of the air vents on different sides of the prism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention achieves airflow from all four directions (top, bottom, and sides) to a tea table air conditioner by controlling the forward and reverse rotation of the motor and controlling the air inlet and outlet switches, thus providing cooling or heating. Furthermore, it prevents direct airflow by determining the user's desired direction and rotating the unit or controlling the air outlet switch.

[0018] The umbrella's rain protection function is achieved through rain detection and control, while its airflow control also enables cold air to settle and prevent direct drafts. This provides customers in the open outdoor space with a comfortable environment that remains suitable for various weather conditions, thereby improving seating utilization and customer satisfaction. Its core structure includes a heat exchange module located in the center of the tea tabletop and an umbrella structure above it; the two work together to provide corresponding functions in various scenarios, including cooling, heating, and rain protection.

In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0027] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example

[0029] like Figure 1 As shown, this embodiment uses an air conditioning unit (also called a desktop air conditioner) for use on a tea table as an example for explanation. The air conditioning unit includes a heat exchange module, which is located in the center of the tea table. The heat exchange module is equivalent to the indoor unit of the air conditioner. The heat exchange module is equipped with a heat exchanger 3, a heat exchange fan 4, and an upper air outlet 5 and a lower air outlet 6 located on the upper and lower sides of the heat exchanger 3. The outdoor unit of the air conditioning unit can be placed in other positions and connected to the heat exchange module shown as the indoor unit through refrigerant pipes to form an air conditioning system. Of course, this is conventional technology in this field and will not be described in detail here. The heat exchanger 3 shown can be, for example, a finned heat exchanger, and the heat exchange fan 4 is an axial flow fan with switchable airflow direction, also referred to here as the main fan. In heating mode, the heat exchange fan 4 causes the airflow to enter from the upper air inlet 5 and exit from the lower air inlet 6, which facilitates the hot airflow to heat the surrounding space from bottom to top; while in cooling mode, the heat exchange fan 4 causes the airflow to enter from the lower air inlet 6 and exit from the upper air inlet 5, which facilitates the cold airflow to cool the surrounding space from top to bottom.

[0030] like Figure 2 As shown, a fan umbrella is provided above the heat exchange module. This fan umbrella structure is used to further adjust the direction and distribution of airflow. The fan umbrella includes a canopy 8, an air supply pipe 9, and an air supply power device 10 mounted on the air supply pipe 9. The air supply power device 10 can be, for example, an air pump or other power device capable of increasing airflow velocity; in this embodiment, it is referred to as a fan umbrella motor. One end of the air supply pipe 9 corresponds to the center below the canopy 8, and the other end is connected to the upper air inlet 5 and the lower air inlet 6 respectively via two control valves. That is, the end of the air supply pipe 9 has two air inlet ports, corresponding to the upper air inlet 5 and the lower air inlet 6 respectively. Each air inlet port is equipped with a control valve to control the opening and closing state of the air inlet port, thereby selectively delivering cooling or heating airflow to the fan umbrella. After exiting from the upper port of the air supply duct 9, the airflow is sprayed onto the surface below the umbrella cover 8, and then guided to the surrounding area by the inner surface of the umbrella cover 8. This creates a larger "umbrella" covering the heat exchange module. The umbrella cover 8 not only reflects the airflow but also provides rain protection. In rainy weather, the airflow sprayed from below the umbrella forms a circumferential air curtain under the reflection of the umbrella cover 8. This air curtain disperses the falling raindrops, preventing rainwater from directly falling on the tea table or customers, thus achieving the effect of "airflow rain protection." This design allows customers to use the tea table outdoors without getting wet in the rain, significantly improving the utilization rate of the open seating area.

[0031] When the air conditioner is in cooling mode, the control unit opens the control valve connected to the upper air vent 5 and closes the control valve connected to the lower air vent 6. Cool air enters the air supply duct 9 through the upper air vent 5 and is accelerated and ejected by the air supply power unit 10, impacting the lower surface of the umbrella 8 and being reflected into the surrounding area, forming a layer of cool air covering the tea table and surrounding seats. This layer of cool air effectively lowers the local ambient temperature, creating a comfortable cooling zone centered on the tea table, especially suitable for use in hot summer weather. When the air conditioner is in heating mode, the control unit opens the control valve connected to the lower air vent 6 and closes the corresponding valve at the upper air vent 5. Hot air enters the air supply duct 9 through the lower air vent 6 and is ejected towards the lower part of the umbrella 8. After reflection, it diffuses along the curved surface of the umbrella 8 to the surrounding area, forming a downward-facing layer of warm air. This causes the temperature of the space around the customers to rise evenly, providing a continuous thermal comfort environment in winter or cold weather. Of course, in heating mode, hot air rises, so the air coming out of the heating umbrella cannot achieve a good heating effect. In order to improve the heating effect, the edge of the umbrella cover 8 can be made to face downwards as much as possible, or the height of the umbrella cover 8 can be adjusted. When heating is needed, the umbrella cover 8 can be lowered. The specific lifting structure can be set as needed, which will not be elaborated here.

[0032] In summary, this embodiment combines a heat exchange module, a reversible fan, and a canopy with an air duct 9 and a canopy 8 to achieve triple functions of cooling, heating, and rain protection. Its working principle lies in utilizing a controllable airflow path and the guiding effect of the canopy 8 to flexibly change the direction and distribution of airflow, thereby achieving air temperature regulation and airflow shielding. Unlike traditional fixed air conditioners or parasols, this solution is compact, functionally integrated, and highly adaptable. It can provide localized cooling in hot weather, localized heating in cold weather, and form an effective airflow protection layer in rainy weather, thus maintaining a comfortable customer experience under various weather conditions and significantly improving the utilization rate of outdoor seating and the overall operating efficiency of the store.

[0033] Furthermore, the heat exchange module has several upper air inlets 5 arranged circumferentially on its upper part, and several lower air inlets 6 corresponding vertically to each of the upper air inlets 5 on its lower part. In this embodiment, there are four upper air inlets 5 and four lower air inlets 6.

[0034] Multiple sets of air vents arranged vertically create a uniform airflow circulation channel within the heat exchange module. In cooling mode, cool air enters through the lower vent 6, undergoes heat exchange, and is then evenly expelled from the upper vent 5, forming a circumferential cool airflow and improving the uniformity of cooling the surrounding air. In heating mode, hot air enters through the upper vent 5 and exits through the lower vent 6, achieving a circumferential rising hot airflow and making heat distribution more uniform. This structure effectively improves heat exchange efficiency and airflow coverage, enhancing user comfort.

[0035] Furthermore, a rainwater detector 11 is provided on the umbrella cover 8, and the air supply power device 10 controls its working state according to the detection information of the rainwater detector 11.

[0036] A rain detector 11 is installed on the umbrella cover 8 to detect whether there is rainfall in the environment in real time. When raindrops are detected, the rain detector 11 transmits a signal to the control unit, which then activates the air supply power unit 10, causing airflow to be ejected through the air supply pipe 9 and forming a circumferential air curtain under the umbrella cover 8, blowing the falling raindrops away from the tea table area, thereby achieving an automatic rain protection function; when the detector detects no rain, the air supply power unit 10 can be automatically turned off by the control system to reduce energy consumption.

[0037] Furthermore, both the upper air inlet 5 and the lower air inlet 6 are equipped with air-sweeping plates 7. The air-sweeping plates 7 are controlled to rotate by a rotating device. When the air-sweeping plates 7 are open, the upper air inlet 5 faces upward and the lower air inlet 6 faces downward. The rotating device can be, for example, a motor. The air-sweeping plates 7 of the upper air inlet 5 are controlled to rotate by the motor of the upper air inlet 5, and the air-sweeping plates 7 of the lower air inlet 6 are controlled to rotate by the motor of the lower air inlet 6.

[0038] The air sweeper 7 is driven by a rotating device to adjust its angle. When the air sweeper 7 is open, the air sweeper 7 at the upper air outlet 5 tilts upwards, and the air sweeper 7 at the lower air outlet 6 tilts downwards, making the airflow direction more in line with the natural flow law of hot and cold air: hot air rises when heating and cold air sinks when cooling, thereby enhancing air circulation efficiency and comfort. At the same time, the adjustable angle design of the air sweeper 7 can also flexibly guide airflow according to environmental needs, avoid direct airflow, and improve the uniformity of local airflow distribution and human experience.

[0039] Furthermore, the umbrella cover 8 is supported on top of the heat exchange module via the air supply pipe 9. The heat exchange module is provided with a rotating base 12, which allows the heat exchange module to rotate about a vertical axis. The axis of rotation of the rotating base 12 is coaxial with the umbrella cover 8. A body rotation motor 13 is provided on the rotating base 12 to control the rotation of the heat exchange module body.

[0040] The heat exchange module is equipped with a rotating base 12, allowing the airflow direction to be adjusted according to usage scenarios or wind direction requirements, thus preventing airflow from blowing directly on customers for extended periods and reducing discomfort caused by strong winds or temperature differences. The umbrella cover 8 is supported and mounted on top of the heat exchange module via an air supply duct 9, and the air supply power unit 10 is also fixed to the inner side of the top of the heat exchange module, forming an integrated structure that serves both as an airflow channel and as support for the umbrella cover 8. The rotating base 12 is located at the bottom of the heat exchange module, with its rotation axis arranged vertically and coaxial with the central axis of the umbrella cover 8, allowing the entire heat exchange module and umbrella cover 8 to rotate synchronously around the vertical axis. This structural design allows for flexible adjustment of the umbrella cover 8 and airflow direction under different wind or sunlight conditions, ensuring that cooling or heating airflow accurately covers the main activity areas of customers. Simultaneously, the rotating base 12 can be automatically or manually adjusted via a motor or angle control mechanism to ensure uniform airflow distribution and improve heat exchange efficiency. This structure not only enhances the flexibility and adaptability of air conditioning equipment, but also optimizes the user experience of outdoor tea tables, enabling the device to maintain an ideal localized comfortable environment under different weather and directional conditions.

[0041] The heat dissipation module is a prism, with an upper air vent 5 and a lower air vent 6 on each side. In this embodiment, the heat dissipation module is a quadrangular prism, i.e., a rectangular cabinet. Preferably, the tea table is rectangular, allowing four users (guests) to use it from each of its four sides.

[0042] In other words, the heat dissipation module has a prism-like structure, with an upper air vent 5 and a lower air vent 6 on each side to achieve multi-directional air supply and intake, thereby expanding the airflow coverage and enhancing the air circulation effect. Preferably, the heat dissipation module has a quadrangular prism structure, i.e., a rectangular cabinet shape, which allows the internal heat exchanger 3 and air module components to be rationally arranged along the axial direction, resulting in a stable structure and easy installation. This four-sided air distribution design can evenly distribute cool air in all directions in cooling mode and release hot air circumferentially in heating mode, ensuring a balanced temperature distribution around the tea table, significantly improving the comfort of the local environment and heat exchange efficiency, while also enhancing the overall aesthetics and spatial adaptability of the device.

[0043] Furthermore, the tea table is equipped with multiple control switches, namely desktop switch buttons (not shown in the figure). Different control switches control the opening and closing state of the air vents on different sides of the prism. In this embodiment, there are four control switches, corresponding to the four sides of the rectangular cabinet of the heat dissipation module. Users can also set the airflow requirements from their seat direction and control the opening and closing of the four air vents.

[0044] The tea table is equipped with multiple independent control switches, each used to independently control the opening and closing of the air vents on each side. Users can selectively open the air vents in the corresponding direction according to the seating arrangement or environmental needs, achieving directional airflow or localized cooling / heating control. For example, opening the air vents only on the side with customers can provide comfortable airflow, while the unused sides can be closed to reduce energy consumption. This design not only improves the flexibility and energy efficiency of the equipment but also avoids the decrease in comfort caused by ineffective airflow, further enhancing the customer experience and system operating efficiency.

[0045] like Figure 3 As shown, for ease of control, it can also be controlled with a touch screen or other control terminal, as well as a wireless control module to meet the remote control needs of mobile devices (such as mobile phones). The heat exchange fan shown is the main fan in the figure. The rainwater detector can be, for example, a rainwater detection sensor of model RK400-02. The various components of the system can be controlled by electronic controllers such as MCUs. How to make these power electronic devices form a control system that can execute this embodiment is a conventional technology in the field of electronic control technology, and will not be described in detail here.

[0046] like Figure 4 As shown, the control mode of the heat exchange module is as follows:

[0047] Step 1: First, perform mode detection to determine whether the user has set a cooling or heating mode. Alternatively, in automatic mode, the module can automatically determine the cooling or heating mode based on the user-set temperature. If it is cooling mode, set the fan to rotate forward, with the lower air outlet as the return air outlet and the upper air outlet as the air outlet. The upper air outlet can also be set to swing. If it is heating mode, set the fan to rotate in reverse, with the upper air outlet as the return air outlet and the lower air outlet as the air outlet. The lower air outlet can also be set to swing.

[0048] Next, the module switch is checked to determine whether any of the four user switches on the desktop are set to the "on" state (the switch status can be indicated by indicator lights). If one of them is set to "on", the module is started and enters the power-on state, then proceeds to step two. If all four switches are set to "off", the module is shut down, the fan is stopped, and all air inlets and outlets are closed.

[0049] Step 2: Check if the user has set the anti-direct-blowing function. If not, proceed to steps 3 and 4; if yes, proceed to steps 3 and 5.

[0050] Step 3: Fan control: In cooling mode, the fan rotates forward, and the air inside the module flows from bottom to top. In heating mode, the fan rotates in reverse, and the air inside the module flows from top to bottom. Return air vent control: When the unit is turned on, all return air vents are opened.

[0051] Step 4: When the machine is powered on, the air outlet control without anti-direct-blow function is not set; the status of the user switch indicates that there is an opening requirement in the corresponding direction. When a user switch is set to on, the air outlet in the corresponding direction will be opened; when the user switch is on, the corresponding air outlet can be put into and taken out of the swing mode by pressing and holding the user switch.

[0052] Step 5: With the unit powered on, set the air outlet control for the anti-direct-blow function: Start the unit's rotation motor and rotate the unit 45° clockwise (or counterclockwise) (the desktop will not rotate); the status of the user switches indicates the direction in which the corresponding position needs to be opened. When one user switch is set to "on", the air outlets on both sides of the corresponding direction will be opened; an air outlet is controlled by two user switches. It will be opened when at least one user switch is "on" and closed when both user switches are "off".

[0053] like Figure 5 As shown, the umbrella is controlled as follows:

[0054] Step 1: Check if a rain detector is installed. If yes, it means the user has installed an umbrella accessory, and proceed to Step 2; if no, it means the user has not installed an umbrella accessory, and repeat Step 1.

[0055] Step 2: Check if the rain detector has detected water. If yes, determine that it is raining, turn on the air supply power unit, and proceed to Step 3. If no, repeat Step 2.

[0056] Step 3: Determine whether the current mode is cooling or heating. If it is cooling, open control valve 2 corresponding to the upper air vent; if it is heating, open control valve 1 corresponding to the lower air vent.
