Description
Technical Field
The invention belongs to the technical field of intelligent home, and relates to a water circulation temperature control mattress based on feedback logic.
Background
The water circulation heating technology is widely applied to mattresses, heated warm water is circulated in a water pipe paved in the mattress in a water circulation mode, so that the purpose of heating is achieved, the existing water circulation mattress is composed of an external water tank, a water pump positioned in the water tank and hoses distributed in the mattress, and the logic of the water circulation mattress is as follows: after the set temperature value, the water in the water tank is heated to the set temperature value, then the water pump is intermittently started, so that the water in the hose and the water in the water tank reaching the set temperature value are mixed, the water temperature in the hose in the mattress is set as the set value, and the existing water circulation heating mattress and the control logic thereof have the following defects: 1. the starting interval of the water pump and the maintaining time after the water pump is fixed, so that the time for the mattress to reach the set temperature in the initial state is longer, and the temperature in the hose can reach the set value only by slowly heating for more than ten minutes; 2. the existing mode is to control the temperature of water in a water tank, but not the temperature of water in a hose, in fact, due to the reasons of human body heating, bedding covering and the like, the temperature of water in the hose wrapped and in the bedding covering is possibly higher than the temperature of water in the water tank, for example, after sleeping in a deep state, the bedding better covers the water pipe, human body heating and gathering are not easy to be dispersed, so that the temperature of a mattress is higher than a set value, at the moment, discomfort of the human body can be caused, and the actions such as quilt kicking and the like can cause cold catching; 3. the action frequency and single duration of the water pump cannot be adjusted according to actual conditions, even if the water temperature in the hose is almost the same as the water temperature in the water tank, the water pump still acts, so that the energy consumption is high, and the high-frequency action (especially at night) of the water pump can cause noise to a certain extent; 4. in the prior art, the water circulation mattress cannot be cooled, and in the actual use process, the conditions of getting up, turning the bedding and the like possibly exist before sleeping at the set temperature, so that a user cannot feel the excessively high temperature in the bedding, but when the mattress enters a sleeping state at the set temperature, the condition of turning the bedding is greatly reduced, the actions of people are less, the heat exchange efficiency between the inside of the bedding and the indoor is lower, and the conditions of heating of a human body and the like possibly cause the discomfort of people due to the higher temperature in the bedding, and the temperature needs to be reduced, so that the prior art cannot achieve the problem.

The operation logic and flow of the control unit of the water circulation temperature control mattress are as follows: the user lies on the mattress, and the water pillow bears the head of people, makes electric three-way valve one and electric three-way valve two all be in initial state, namely: the first and second power-on coils are powered off, the water pump is stopped, the heating strip is powered off, at the moment, the outlet of the first channel on the valve column is communicated with the first water inlet connecting pipe, the inlet of the first channel is communicated with the water inlet joint, the outlet of the second channel on the valve column is communicated with the water outlet joint, the inlet of the second channel is communicated with the second water outlet connecting pipe, the pillow cavity with large volume and sensitive deformation is pressed due to the turning of the head and the extrusion of the water pillow, the water in the pillow cavity is increased, the water in the hose enters the inlet of the cavity, the temperature sensor detects the temperature of the water in the hose, if the temperature is maintained in a set temperature range, the initial state is maintained, if the set temperature is 35 ℃, and the temperature range for maintaining the initial state can be set to be 34-36 degrees; if the temperature of the water in the hose is detected to be higher than the set range, the water pump is started, the heating strip is kept in a power-off state, the first coil is electrified, the second coil is powered off, the water inlet connector is communicated with the second water inlet connecting pipe through the first channel, the water in the hose and the water in the pillow cavity are subjected to heat exchange, the pillow cavity is positioned outside the bedding and is not covered, the indoor temperature can be generally kept, when the temperature of the water in the hose is higher than the set value, the temperature of the water in the pillow cavity is lower than the temperature of the water in the hose, the temperature of the water in the hose can be reduced through heat exchange between the pillow cavity and the hose, the water pump is stopped after a few seconds of operation, and the power-on coil is powered off, so that the mattress enters an initial state; in the process of pressing the pillow cavity, water in the hose in an initial state is continuously subjected to detection of a temperature sensor, if the temperature of the water in the hose is detected to be smaller than a set range, a water pump is started, a heating strip is electrified, a second coil is electrified, a first coil is powered off, a water inlet connector is communicated with a first water inlet connecting pipe through a first channel, the water in the hose and the water heated by the heating strip in a cavity are subjected to heat exchange, so that the water temperature in the hose is increased, in the circulation process, the water in the hose is continuously subjected to the detection of the temperature sensor, and when the temperature value changes, the logic is repeated.
As is well known, when the body feel is uncomfortable, the frequency and the amplitude of the body turning over can be increased, so that the monitoring frequency of the temperature sensor to the water temperature in the hose can be increased, and the monitoring frequency can be reduced in a comfortable and deep sleep state, therefore, the control of the circulating water mattress is more accurate, and the control mode is more fit with the requirements of users.
Because the water tank of traditional circulating water mattress needs to occupy great space, and is located the bedside cupboard etc. generally, the operation is inconvenient, and the user needs to rise to control it, uses inconveniently, and this scheme then sets up the water tank into the pillow, has not only improved the travelling comfort, can utilize moreover to realize being suitable for the control mode of demand, need not to consider the operation.
The water pillow is in a strip shape transversely arranged at the bed head, can be directly used as a pillow, and can be placed on the water pillow, most of the water pillow is in a naked state because the width of the water pillow is almost equal to that of a mattress, and can keep the same with room temperature or exchange heat with the room, so that the temperature of the water pillow is lower than that of a hose needing heating.
The water pillow is made of silica gel materials, the retaining cavity has certain deformation capability, but due to the fact that the space is small, the volume of the pillow cavity is large, a partition plate between the retaining cavity and the pillow cavity can provide certain rigidity for the retaining cavity, when the water pillow is pressed from top to bottom, the volume change in the pillow cavity is large, water in a hose can be ensured to receive detection of a temperature sensor in an initial state, and in order to further improve reliability, one-way valves can be arranged in a first water inlet connecting pipe, a second water inlet connecting pipe, a first water outlet connecting pipe and a second water outlet connecting pipe, so that the circulation direction of water is ensured to be a required direction.
