Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a sparkling water machine. Background Art

[0002] Nowadays, with the improvement of living quality, people usually inject carbon dioxide gas into water when drinking water. After the carbon dioxide gas is fully mixed with water, the taste can be improved. In order to facilitate inflation, instant sparkling water machines have emerged on the market. The existing instant sparkling water machines usually adopt high-pressure inflation technology to inject carbon dioxide gas into the water in the mixing chamber to form sparkling water. The instant sparkling water machine is widely used because it is safer, has fast water output, and low cost. However, at present, the water outlet of the instant sparkling water machine generally adopts a direct drainage type. During the inflation process, the pressure in the mixing chamber gradually increases. When draining water, the water-vapor mixture is directly discharged from the mixing chamber under high pressure, and it is easily affected by the high pressure in the mixing chamber, resulting in splashing of the water output.

[0003] To solve the above problems, a water-vapor separator is generally arranged on the water outlet pipeline, which can reduce the pressure of the water-vapor mixture and effectively prevent splashing when the sparkling water is discharged.

[0004] For example, the prior art CN219374394U discloses a water and gas separation box with exhaust, and specifically discloses a separation box main body and an exhaust and drainage three-way joint connected to the separation box main body; an inlet is arranged on the side of the separation box main body, and a water outlet is arranged at the bottom of the separation box main body; the exhaust and drainage three-way joint includes an air inlet end, a water inlet end, and an output end. The output end is arranged between the air inlet end and the water inlet end, and the opening positions of the air inlet end and the water inlet end are higher than the opening position of the output end; the output end is inserted and fixed with the inlet. An exhaust end is arranged along the inner part of the separation box main body around the water outlet. And in a specific embodiment, 2 blocking ribs are arranged, which can play a certain buffering role for the water entering the separation box main body, avoiding too much impact force of the water flow after the water enters the separation box main body and damaging the structure of the separation box main body. However, in the above prior art, due to the lack of a structure for stabilizing the internal pressure of the separation box main body, with the gas discharged through the exhaust end, the internal pressure of the separation box main body will change greatly, still possibly resulting in splashing of the water output, and the water output flow rate is unstable, sometimes large and sometimes small, affecting the user experience. Summary of the Utility Model

[0005] The utility model aims to overcome the deficiencies in the prior art, and provides a sparkling water machine, which separates gas from high-pressure sparkling water, avoids splashing during the discharge of sparkling water at the water outlet, and improves the stability of the water output flow rate.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a bubble water machine, including a water supply component, an air supply component, a mixing chamber and a gas-liquid separator, the water supply component is connected with the mixing chamber to supply water thereto, the air supply component is connected with the mixing chamber to supply air thereto, the gas-liquid separator has a gas-liquid separation chamber, a water inlet, a water outlet and an exhaust port, the gas-liquid separation chamber is connected with the outlet of the mixing chamber through the water inlet, the bubble water in the gas-liquid separation chamber is discharged through the water outlet, and the gas is discharged through the exhaust port, the exhaust port is provided with a pressure relief valve, and a baffle is provided in the gas-liquid separation chamber to prevent the high-pressure bubble water flowing in from the water inlet from rushing open the pressure relief valve, and the baffle is blocked between the impact path of the high-pressure bubble water and the pressure relief valve.

[0007] After adopting the above technical scheme, the utility model has the following advantages: the exhaust port is provided with a pressure relief valve, and the pressure relief valve will open the exhaust port to relieve pressure only after the pressure in the gas-liquid separation chamber reaches a certain threshold value, and when the pressure in the gas-liquid separation chamber drops below the corresponding threshold value, the pressure relief valve will close the exhaust port again. Therefore, it can be ensured that the pressure in the gas-liquid separation chamber is in a dynamic equilibrium state, the pressure change is small, and it is in a relatively stable state, so that the bubble water is not easy to splash when discharged from the water outlet, and the water outlet flow rate is relatively stable and will not fluctuate, which can improve the user experience. Because the exhaust port and the water inlet are both connected to the gas-liquid separation chamber and the impact force of the high-pressure bubble water is relatively large, in order to prevent the high-pressure bubble water from directly rushing open the pressure relief valve after entering the gas-liquid separation chamber and causing the pressure relief valve to fail, a baffle is provided between the impact path of the high-pressure bubble water and the pressure relief valve. After the high-pressure bubble water enters the gas-liquid separation chamber through the water inlet, most of the impact force of the high-pressure bubble water can be offset by the baffle, while promoting gas-liquid separation, effectively preventing the high-pressure bubble water from directly or indirectly rushing towards the pressure relief valve, causing the pressure relief valve to open accidentally.

[0008] Furthermore, the exhaust port and the water inlet are located on the same side of the gas-liquid separation chamber, and the exhaust port is located above the water inlet, the baffle extends downward and avoids the high-pressure bubble water, the inner wall of the gas-liquid separation chamber includes a first side surface, the high-pressure bubble water passes over the baffle and impacts the first side surface, and the baffle is blocked between the first side surface and the pressure relief valve to prevent the high-pressure bubble water from rebounding through the first side surface.

[0009] By adopting the aforementioned technical solution, the exhaust port and the water inlet are located on the same side of the gas-liquid separation chamber, and the exhaust port is located above the water inlet. The baffle extends downward to cover the exhaust port, which can timely block the high-pressure bubble water rebounded by the first side, thereby effectively preventing the rebounded high-pressure bubble water from rushing to the pressure relief valve. The rebounded high-pressure bubble water hits the baffle again, which can further reduce the impact force and promote gas-liquid separation.

[0010] Furthermore, the water inlet is arranged transversely, and the bottom end of the baffle is higher than the midpoint of the height of the water inlet cross section.

[0011] With the foregoing technical solution, high-pressure bubble water will be sprayed horizontally into the gas-liquid separation chamber from the water inlet. Affected by gravity, the spraying path of the high-pressure bubble water is a relatively smooth parabolic shape. The bottom end of the baffle is higher than the midpoint of the height of the water inlet cross-section. This structure neither blocks the normal entry of high-pressure bubble water into the gas-liquid separation chamber nor can effectively block the high-pressure bubble water rebounding towards the pressure relief valve.

[0012] Furthermore, the bottom end of the baffle is lower than the upper edge of the water inlet cross-section.

[0013] With the foregoing technical solution, it is possible to avoid high-pressure bubble water splashing onto the exhaust port to the greatest extent while not blocking the normal entry of high-pressure bubble water into the gas-liquid separation chamber. At the same time, setting the baffle to this length also ensures that there is a certain gap between the baffle and the high-pressure bubble water, ensuring that the high-pressure bubble water enters the gas-liquid separation chamber without affecting the exhaust.

[0014] Furthermore, the exhaust port and the water inlet are respectively located on both sides of the gas-liquid separation chamber. The baffle extends downward and faces the water inlet, and the high-pressure bubble water impacts on the baffle.

[0015] With the foregoing technical solution, when the high-pressure bubble water enters the gas-liquid separation chamber, it directly impacts on the baffle, offsetting most of the impact force, avoiding the high-pressure bubble water directly impacting the exhaust port, and at the same time improving the efficiency of gas-liquid separation.

[0016] Furthermore, the top end of the baffle is connected to the top wall of the gas-liquid separation chamber and the side of the baffle is connected to the side wall of the gas-liquid separation chamber; or, the top of the baffle is provided with a ventilation hole penetrating the baffle.

[0017] With the foregoing technical solution, in the former solution, the baffle has good structural strength and can withstand long-term high-pressure impacts; in the latter solution, by setting the baffle to divide the gas-liquid separation chamber into two parts of space. When the high-pressure bubble water enters the gas-liquid separation chamber, in order to discharge the gas from the exhaust port in time, a ventilation hole penetrating the baffle is provided on the baffle. When the bottom of the gas-liquid separation chamber is filled with liquid, the gas in the space on the side of the baffle facing away from the exhaust port can flow through the ventilation hole to the space on the side of the baffle facing the exhaust port and then be smoothly discharged through the exhaust port.

[0018] Furthermore, the pressure relief valve includes a pressure relief thimble and an elastic member. The pressure relief thimble cooperates with the exhaust port and has a tendency to keep the exhaust port closed under the elastic force of the elastic member.

[0019] With the foregoing technical solution, when the pressure in the gas-liquid separation chamber is higher than that outside the chamber, the gas in the gas-liquid separation chamber pushes the pressure relief thimble to open the exhaust port. At this time, the exhaust port exhausts. When the pressure in the gas-liquid separation chamber drops and the pressure acting on the pressure relief thimble is less than the elastic force of the elastic member, the elastic member will push the pressure relief thimble back to its original position and the exhaust port closes, thus realizing the dynamic balance of the pressure in the gas-liquid separation chamber.

[0020] Further, a pressure relief joint is provided at the exhaust port. One end of the elastic member abuts against the pressure relief joint. The pressure relief joint is connected to the exhaust port and axially adjusts its position relative to the exhaust port to adjust the elastic force of the elastic member.

[0021] With the foregoing technical solution, one end of the pressure relief joint abuts against the elastic member. By adjusting the axial position of the pressure relief joint relative to the exhaust port, the elastic force of the spring is controlled, thereby controlling the pressure relief range, and making the pressure relief range of the gas-liquid separator adjustable.

[0022] Further, a water outlet regulating valve for adjusting the water output is provided at the water outlet.

[0023] With the foregoing technical solution, the water output can be adjusted according to requirements to meet different usage conditions.

[0024] Further, the water outlet regulating valve includes a regulating valve core connected to the water outlet. An annular water outlet gap is formed between the front end of the regulating valve core and the water outlet. The regulating valve core moves axially relative to the water outlet to change the size of the water outlet gap so as to adjust the water output.

[0025] With the foregoing technical solution, an annular water outlet gap is formed between the front end of the regulating valve core and the water outlet, which can further prevent splashing during the discharge of bubble water at the water outlet, stabilize the water output, and change the size of the water outlet gap by the axial movement of the regulating valve core to adjust the water output, which can not only meet the need to adjust the size of the water flow, but also maintain the annular structure of the water outlet gap.

[0037] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. The same or similar concepts or processes may not be repeated in some embodiments.

[0038] As Figures 1 to 8As shown in the figure, the present utility model provides a sparkling water machine, which includes a water supply component 4, a gas supply component 6, a mixing chamber 2 and a gas-liquid separator 1. The water supply component 4 is connected to the mixing chamber 2 to supply water thereto, and the gas supply component 6 is connected to the mixing chamber 2 to supply gas thereto. The gas-liquid separator 1 has a gas-liquid separation chamber 100, a water inlet 13, a water outlet 12 and an exhaust port 11. The gas-liquid separation chamber 100 is connected to the outlet of the mixing chamber 2 through the water inlet 13. The sparkling water in the gas-liquid separation chamber 100 is discharged through the water outlet 12, and the gas is discharged through the exhaust port 11. A pressure relief valve is provided at the exhaust port 11, and a baffle 14 is provided in the gas-liquid separation chamber 100 to prevent the high-pressure sparkling water flowing in from the water inlet 13 from flushing open the pressure relief valve. The baffle 14 is blocked between the impact path of the high-pressure sparkling water and the pressure relief valve. In the present utility model, a pressure relief valve is provided at the exhaust port. The pressure relief valve will only open the exhaust port 11 to relieve pressure when the pressure in the gas-liquid separation chamber 100 reaches a certain threshold, and when the pressure in the gas-liquid separation chamber 100 drops below the corresponding threshold, the pressure relief valve will close the exhaust port 11 again. Therefore, it can ensure that the pressure in the gas-liquid separation chamber 100 is in a dynamic balance state, the pressure change is small, and it is in a relatively stable state. Thus, when the sparkling water is discharged from the water outlet 12, it is not easy to splash, and the water discharge flow is relatively stable, not large or small suddenly, which can improve the user experience.

[0039] It can be understood that because both the exhaust port 11 and the water inlet 13 are connected to the gas-liquid separation chamber 100, and the impact force of the high-pressure sparkling water is relatively large, in order to prevent the high-pressure sparkling water from directly flushing open the pressure relief valve after entering the gas-liquid separation chamber 100 and causing the pressure relief valve to fail, a baffle 14 is provided between the impact path of the high-pressure sparkling water and the pressure relief valve. After the high-pressure sparkling water enters the gas-liquid separation chamber 100 through the water inlet 13, the baffle 14 can first offset most of the impact force of the high-pressure sparkling water, and at the same time promote gas-liquid separation, effectively avoiding the high-pressure sparkling water directly or indirectly rushing towards the pressure relief valve and causing the pressure relief valve to open accidentally.

[0040] In one embodiment, the gas-liquid separator 1 includes an upper shell 15, a lower shell 16 and a housing sealing ring 17. A groove is provided on the lower shell 16. The housing sealing ring 17 further has a triangular rib structure. The housing sealing ring 17 is assembled in the groove of the lower shell 16 with the triangular rib structure facing upward. The upper shell 15 and the lower shell 16 are respectively provided with five groups of corresponding mounting holes 18, and are locked through the screws 19, so that the triangular rib structure closely adheres to the end face of the upper shell 15. The housing sealing ring 17 can ensure the airtightness of the gas-liquid separation chamber 100. Preferably, only in this embodiment, it is considered that the effect of using the screws 19 to fix the upper shell 15 and the lower shell 16 is better. Further, the number of the specific mounting holes 18 can also be increased or decreased according to requirements, and there is no mandatory limit. Further, the upper shell 15 and the lower shell 16 can also be connected by means of adhesion, clamping, welding, etc., and there is no specific limit in the specific application, so no more details will be described here, as long as the purpose of tightly and hermetically connecting the upper shell 15 and the lower shell 16 is achieved.

[0041] In one embodiment, the exhaust port 11 and the water inlet 13 are located on the same side of the gas-liquid separation chamber 100, and the exhaust port 11 is located above the water inlet 13. At the same time, the baffle 14 extends downward and avoids the high-pressure bubble water. The inner wall of the gas-liquid separation chamber 100 includes a first side surface 101. The high-pressure bubble water crosses the baffle 14 and impacts the first side surface 101. The baffle 14 blocks between the first side surface 101 and the pressure relief valve to block the high-pressure bubble water rebounding from the first side surface 101, as Figure 2 shown by the arrow in the figure. It can be understood that since the exhaust port 11 and the water inlet 13 are located on the same side of the gas-liquid separation chamber 100 and the exhaust port 11 is located above the water inlet 13, a baffle 14 is provided to extend downward to block the exhaust port 11. When the high-pressure bubble water enters the gas-liquid separation chamber 100 through the water inlet 13, the high-pressure bubble water rebounding from the first side surface can be blocked in time, thereby effectively preventing the high-pressure bubble water rebounding from rushing towards the pressure relief valve. Moreover, the high-pressure bubble water rebounding and impacting the baffle again can further reduce the impact force and also promote gas-liquid separation.

[0042] Further, the top end of the baffle 14 is connected to the top wall of the gas-liquid separation chamber 100, the side of the baffle 14 is connected to the side wall of the gas-liquid separation chamber 100, and a vent hole 141 penetrating the baffle 14 is provided at the top of the baffle 14. It can be understood that the baffle 14 is arranged on the top wall of the gas-liquid separation chamber 100 and divides the gas-liquid separation chamber 100 into left and right parts by the baffle 14. When the high-pressure bubble water enters the gas-liquid separation chamber 100, the bottom is filled with liquid. At this time, the gas floating above the left half cannot be discharged. Therefore, by providing the vent hole 141 penetrating the baffle 14 on the baffle 14, the left half is communicated with the right half. While ensuring that the liquid will not impact the exhaust port 11, the gas floating above the left half can be discharged in time. In addition to providing the vent hole 141, a gap can also be designed between the side of the baffle 14 and the side wall of the gas-liquid separation chamber 100, and the gas flows from above the left half into the right half through this gap.

[0043] In order to improve the structural strength of the baffle and withstand long-term high-pressure impact, the top end of the baffle 14 can be designed to be connected to the top wall of the gas-liquid separation chamber 100 and the side of the baffle 14 is connected to the side wall of the gas-liquid separation chamber 100.

[0044] Reference Figure 2 , in one embodiment, the exhaust port 11 and the water inlet 13 are located on the same side of the gas-liquid separation chamber 100, and the exhaust port 11 is located above the water inlet 13. The baffle 14 extends downward, the water inlet 13 is arranged horizontally, and the bottom end of the baffle 14 is higher than the midpoint of the height of the cross section of the water inlet 13. It can be understood that the high-pressure bubble water will be sprayed horizontally into the gas-liquid separation chamber 100 from the water inlet. Affected by gravity, the spraying path of the high-pressure bubble water is a relatively smooth parabola. The bottom end of the baffle 14 is higher than the midpoint of the height of the cross section of the water inlet. This structure neither blocks the normal entry of the high-pressure bubble water into the gas-liquid separation chamber 100, nor can effectively block the high-pressure bubble water rebounded and rushed towards the pressure relief valve. On this basis, the bottom end of the baffle 14 is lower than the upper edge of the cross section of the water inlet 13, which can avoid the high-pressure bubble water splashing onto the exhaust port to the greatest extent while not blocking the normal entry of the high-pressure bubble water into the gas-liquid separation chamber 100. At the same time, setting the length of the baffle 14 also ensures that there is a certain gap between the baffle 14 and the high-pressure bubble water to ensure that the high-pressure bubble water enters the gas-liquid separation chamber 100 without affecting the exhaust.

[0045] As mentioned above, the exhaust port 11 is provided with a pressure relief valve. In one embodiment, the pressure relief valve includes a pressure relief thimble 112 and an elastic member 111. The pressure relief thimble 112 cooperates with the exhaust port 11 and has a tendency to keep the exhaust port 11 closed under the elastic force of the elastic member 111. Preferably, in this embodiment, the elastic member 111 is set as a spring, or it can also be an elastic sheet, etc., which will not be specifically described herein. When the pressure in the gas-liquid separation chamber 100 is higher than that outside the chamber, the gas in the gas-liquid separation chamber 100 pushes the pressure relief thimble 112 to open the exhaust port 11. At this time, the exhaust port 11 discharges gas. When the pressure in the gas-liquid separation chamber 100 drops, the pressure acting on the pressure relief thimble 112 is less than the elastic force of the elastic member 111, and the elastic member 111 will push the pressure relief thimble 112 back to its original position, and the exhaust port 11 closes, thereby realizing the dynamic balance of the pressure in the gas-liquid separation chamber 100.

[0046] Further, the other end of the pressure relief thimble 112 abuts against the inner wall of the exhaust port 11, and a first sealing member 114 is also arranged at the abutting position. Specifically, the first sealing member 114 can be a sealing ring.

[0047] Further, in order to adjust the elastic force of the elastic member 111, a pressure relief joint 113 can be provided at the exhaust port 11. One end of the elastic member 111 abuts against the pressure relief joint 113. The pressure relief joint 113 is connected to the exhaust port 11 and axially adjusts its position relative to the exhaust port 11 to adjust the elastic force of the elastic member 111. It can be understood that one end of the pressure relief joint 113 abuts against the spring. By adjusting the axial position of the pressure relief joint 113 relative to the exhaust port 11, the elastic force of the spring is controlled, so as to control the pressure relief range and make the pressure relief range of the bubble water machine selectable.

[0048] Further, to improve the sealing effect when the exhaust port 11 is closed, the pressure relief joint 113 abuts against the other end of the exhaust port 11, and a second sealing member 115 is also arranged at the abutting position. Specifically, the second sealing member 115 can be a sealing ring.

[0049] For the convenience of adjusting the pressure relief joint 113, preferably, a first internal thread can be provided at the exhaust port 11, and the pressure relief joint 113 is provided with a first external thread that cooperates with the first internal thread. The elastic force of the spring can be adjusted by rotating the pressure relief joint 113 to adjust the pressure range of pressure relief. Further, in this embodiment, the set pressure range of pressure relief is between 0.5 bar and 1 bar. The pressure relief range can not only be limited by the pressure relief joint 113, but also be specifically selected by replacing springs with different elastic coefficients. This selectable method increases the application range of the present utility model.

[0050] In order to achieve adjustable water output, a water outlet regulating valve 121 is provided at the water outlet 12, which can adjust the water output flow according to requirements to meet different usage conditions. Specifically, the water outlet regulating valve 121 includes a regulating valve body 1212 tightly connected to the lower shell 16 and a regulating valve core 1211. There is an annular water outlet gap 120 between the front end of the regulating valve core 1211 and the water outlet 12. By adjusting the axial position of the regulating valve core 1211 relative to the water outlet 12, the width of the water outlet gap can be adjusted, thereby changing the water output. An annular water outlet gap 120 is formed between the front end of the regulating valve core 1211 and the water outlet, which can further prevent splashing during the discharge of bubble water at the water outlet 12, stabilize the water output, and adjust the water output by moving the regulating valve core 1211 along the axis to change the size of the water outlet gap 120. This can not only meet the need to adjust the size of the water flow but also maintain the annular structure of the water outlet gap.

[0051] To facilitate the installation and adjustment of the water outlet regulating valve 121, a second external thread can be provided on the outer periphery of the regulating valve body 1212, and a water outlet joint 122 can be provided at the bottom of the lower shell 16. The water outlet 12 passes through the water outlet joint 122, and a second internal thread is provided on the inner wall of the water outlet 12. The second external thread and the second internal thread are connected in cooperation to achieve the sealed connection between the regulating valve body 1212 and the water outlet joint 122, ensuring the tightness and stability of their connection. At the same time, in order to further improve the sealing performance, a third sealing ring 1213 can be added. Further, the front end of the regulating valve core 1211 has a conical surface structure extending into the gas-liquid separation chamber 100, which can play a guiding role when the water flow passes through, making the water flow more stable when entering the water outlet gap. Since the outer periphery of the regulating valve body 1212 is in sealed cooperation with the inner wall of the water outlet 12, in order to smoothly discharge the bubble water, a water passing gap can be provided between the regulating valve body 1212 and the regulating valve core 1211. At the same time, to fixedly connect the regulating valve body 1212 and the regulating valve core 1211, a partition rib 1215 for separating the water flow can be provided between the regulating valve body 1212 and the regulating valve core 1211. A plurality of partition ribs 1215 are distributed around the regulating valve core 1211, and there are water passing holes 1214 between adjacent two partition ribs 1215. The water passing holes 1214 connect the water outlet gap 120 and the water passing gap 1216. The water passing holes 1214 and the water passing gap 1216 can further guide the water flow to accelerate, ensuring the uniformity and stability when the bubble water is discharged. The bottom end of the regulating valve core 1211 should be higher than the bottom end of the regulating valve body 1212, so that the bubble water can reduce the flow rate after passing through the water passing gap and prevent splashing.

[0052] Further, in order to facilitate the operation of adjusting the water outlet control valve 121, an adjustable cross-slot structure 1217 may be provided at the lower end of the control valve core 1211. When a tool such as a cross screwdriver is inserted into the cross-slot structure 1217 to drive the water outlet control valve 121 to rotate, the width of the water outlet gap 120 can be conveniently changed, thereby adjusting the water outlet flow rate. In addition to the cross-slot structure 1217, a flat-slot or Y-slot, etc. may also be used, or a cross rib structure, a flat rib structure or a Y-rib structure, etc. may be used.

[0053] Preferably, in this embodiment, a water outlet nozzle 116 connected to the water outlet joint 122 is further provided below the water outlet control valve 121. A water dividing rib 1221 is provided at the bottom of the water outlet nozzle 116 to break the tension effect of the discharged bubble water and further prevent splashing. The water outlet nozzle 116 can be hermetically connected to the water outlet joint 122 through a threaded structure.

[0054] Further, in order to further ensure the sealing performance between the water outlet joint 122 and the water outlet 12, a fourth sealing ring 1218 is also provided at the abutting portion between the water outlet nozzle 116 and the water outlet joint 122, ensuring the sealing performance.

[0055] In another embodiment, the exhaust port 11 and the water inlet 13 are respectively located on both sides of the gas-liquid separation chamber 100. The baffle 14 extends downward and faces the water inlet 13, and the high-pressure bubble water impacts on the baffle 14. It can be understood that when the exhaust port 11 and the water inlet 13 are located on both sides of the gas-liquid separation chamber 100, facing the baffle 14 to the water inlet 13 can directly impact on the baffle 14 when the high-pressure bubble water enters the gas-liquid separation chamber 100, offsetting most of the impact force, avoiding the high-pressure bubble water directly flushing open the pressure relief valve, and at the same time improving the gas-liquid separation efficiency.

[0056] In the above embodiments, two installation positions of the baffle 14 are listed to achieve a good gas-liquid separation effect. However, in a specific use environment, the position and structure of the baffle 14 are not limited. It can be an inclined angle or connected to the side wall.
